Students believed physics was one of the most challenging sciences in education, and their interest in learning physics was lacking. Therefore, this study aims to enhance students' understanding and creativity in the STEAM learning system on electricity by creating a project (Paper Circuit) using the students' creativity at the junior high school level - quantitative research with a pre-experimental design used for this study. The population is 8th grade and 9th grade (50 students adapted to the curriculum used in the school) in one of the Junior Secondary Schools located in Bandung and Cimahi, Indonesia. The data is obtained from the pretest-posttest results, which show that the average pre-test score was 57.04 and the post-test score was 76.64. The nonparametric test was tested using the Wilcoxon test to measure student understanding. The results from e Wilcoxon are 0.000, which shows sig. <0.05, which means there is a significant difference between pre-test and post-test. Students' creativity is obtained from the Creativity Product Analysis Matrix (CPAM), and the result for Project 1 is 73.71%, categorized as enough, and Project 2 is 83.13%, categorized as good. Based on the result, Paper Circuit STEAM project-based learning can enhance student understanding and creativity. STEAM project-based learning can be used as an alternative teaching strategy in junior secondary school.

Research paper writing is an essential factor and one of the challenging tasks for students. This study aims to examine the effectiveness of the MIRS (Motivation, Inspiration, Realization, and Solution) approach students' capability to write the research papers. This study employed the quasi-experimental design, specifically using equivalent time series method. The subjects of the study were the students of the Culinary Arts of Vocational Education. The research subjects were 154 students. The data were collected using authentic assessment with oral examination on pre-proposal, a paper and pencil (PP) test on research methodology, and a performance test on research proposal seminar. Statistical description and independent sample t-test are used to analyze the results. The results show that the number of the students of treatment group who were able to write innovative research papers increased. The control group's average score of the research paper writing is lower than that of the treatment group. Hypothesis shows that there is difference result between PP testing and oral testing. The alpha score obtains 0,003 for PP testing and 0,002 for oral testing. It can be concluded that MIRS approach is effective for improving writing skill capability.

Paper umbrellas are one of the crafts included in the intangible cultural heritage of Malang, East Java. Currently, it is known that there is only one group of craftsmen who still produce this paper umbrella craft. Although not many of them, this paper umbrella craft still exists among people who like traditional handicrafts. This is evident from how often paper umbrella crafts appear at craft exhibitions in cities in Indonesia. Consequently, there is a pressing need for in-depth research on paper umbrella craftsmanship in Malang City. A valuable avenue for exploration is the examination of non-verbal communication aspects inherent in paper umbrella craftsmanship. This study aimed to determine the non-verbal communication aspects contained in paper umbrella crafts. The research employs a descriptive qualitative approach, focusing on analyzing non-verbal communication aspects. Data was collected using unstructured interview methods, documentation, and field surveys. The collected data was reduced for analysis using nonverbal communication theory. The study findings are presented descriptively, detailing the observed non-verbal communication aspects. The findings reveal three distinct categories of non-verbal communication aspects in paper umbrella craftsmanship: fixed features, semi-fixed features, and non-fixed features. Fixed features include shapes depicted on the umbrella. Semi fixed feature is a choice of material used to make paper umbrellas, colors, and motifs. The materials used are bamboo and paper. The colors of the umbrellas are red and green. The motif drawn on the umbrella is a floral motif. Flowers are present because they are the favorite shapes of the craftsmen who make umbrellas. Non-fixed features encompass the entire process of crafting paper umbrellas, from material preparation to final finishing touches. [ABSTRACT FROM AUTHOR]

Using standardized tests such as paper-based TOEFL with three subtests for classroom assessment is restricted by the length of the test, which is usually longer than the class duration. Therefore, it is significant to be able to predict other subtests by conducting only one subtest. Therefore, the current study aimed to calculate prediction coefficients, enabling teachers to predict scores in paper-based TOEFL by conducting only one subtest. The data to create the prediction models were obtained from 2,030 scores of Institutional TOEFL, i.e. paper-based TOEFL without writing subtest. The prediction coefficient was calculated by using linear regression analysis. The result shows that the listening comprehension sub-score predicts the TOEFL score more accurately (MSE of 520) than other sub-scores (MSE of 553 and 587). The intercept for listening comprehension sub-score was 373.07, 357.14 for structure & written expression, and 364.19 for reading comprehension. In addition, the slope for each sub-score was 4.07, 5.96, and 4.63, respectively. Therefore, a listening test should be used in predicting the overall TOEFL scores for an accurate prediction.

This study aimed at designing a model of instructional materials for Academic Writing Course focusing on research paper writing. The model was designed based on the Curriculum at the English Education Study Program, Faculty of Language and Art Education of IKIP PGRI Bojonegoro, East Java, Indonesia. This model was developed in order to improve students' skill in writing research paper which is one of the prerequisite tasks before graduating from university. The steps of this research and development consist of needs analysis, document analysis, model design, model development, and model experimentation. The researchers conducted needs analysis to the fifth semester students and three academic writing teachers, in order to generate information dealing with the students' needs in academic writing course materials. The needs analysis and documents analysis were dug up through questionnaire, interview, and discussion among students and academic writing teachers. The documents analyzed in this study were syllabus, lesson plan, and the existing textbook. The model design used is derived from Borg and Gall (1983) and Sukmadinata (2008), in which there are four steps, i.e. (1) exploration phase; (2) model development phase; (3) model experimentation phase; and (4) dissemination and model implementation phase. The results of needs analysis questionnaire reveal that students need to be taught how to write academic writing in terms of journal article since it will be the final project of the students at the end of their study in university. Instructional materials with different strategies focused on research paper writing are needed by the students.

Using the newspaper as a medium of learning English is a unique way to stimulate students' interest in reading, since students at this age is a student who has dropped their interest in reading. Therefore, the researchers decided to use the newspaper as a medium to build students' vocabulary. Researcher chose participant in the study of class XB and XE in SMK 45 Lembang. The school gave these two classes as the sample, because believed that each class has the cognitive abilities and knowledge that are relatively equal. In this study, researchers randomly selected from among the two classes used as a sample for the Control and Experimental Class. As the result, researchers found class X E as Control class, and X B as an Experimental class. The study lasted for a full month, in which each class received different treatment. As a result, the Gain value of Experimental class is higher than the Control class. Moreover, based on the result of the data analysis with the Mann-Whitney U test method, it showed that that there were significant differences in Students' Vocabulary growth, between Control class and Experimental class. Based on the calculation of Non-parametric Mann- Whitney U test, the gain data between Experimental Class and Control Class show the value of Asymp Sig. (0.000), Z[alpha] (0.05) and the value of Z (4.847). Z [alpha] (1.96). Therefore, it can be concluded that the method of using newspaper as a teaching material has a positive impact in the absorption and growth in students' vocabulary.

Current trend in education has acknowledged the urgency to move students from the role of traditional receiver and echoer of information to the role of critical listener, speaker, reader, and writer. In so doing, the students need to embrace the role of text analysts who continuously question texts that they encounter. This study looked for indices of students' engagement in text analyst role. The data for the analysis were collected from 25 EFL university students' reviews which were randomly selected. Using the guidepost developed from Luke and Freebody's (1999) Four Resources Framework, the study highlighted points of information and/or questions or issues addressed in the students' writing which indicated students' role as text analysts. The study revealed that 40 percent of the students failed to practice the text analyst role. Meanwhile, those who addressed the role showcased five major patterns of indices: (1) questioned the trustworthiness of text, (2) recognized bias, (3) uncovered hidden intention/agenda, (4) identified harmed/benefitted party, and (5) provided alternate point of view/way of saying and/or personal standing. This study concludes that the students will be able to engage in text analyst role under two conditions (1) they are not struggling with the basic comprehension and (2) they have reached a state of habituation of mind in terms of questioning text. It is therefore recommended that the students be given sufficient time for familiarization and have continuous practices to make a critical approach to texts.

Indonesian lecturers are now encouraged to publish papers in international journals so that they can better disseminate research findings and innovations globally. However, many of them have the problems with English language mastery. This study was aimed at identifying and analyzing language problems of the Indonesian university lecturers in writing English academic papers for international publications. The subjects of the study were 66 randomly selected lecturers of various disciplines other than English Education and English Literature. The data were collected by questionnaire and English writing tasks on phrases, sentences, and paragraphs which were then analyzed descriptively. The results show that language errors and mistakes in grammar, syntax, vocabulary, spelling and word forms were all found in the subjects' writings. In writing academic papers for international publications, university lecturers faced language problems as constructing phrases and sentences, choosing and using appropriate vocabulary and terms relevant to their topic of study as well as translating their Indonesian sentences into English.

Improper disposal of palm biomass wastes resulting from industrial palm oil production may contribute to the environmental issues in Indonesia. However, given their abundance and availability, empty fruit bunches (EFB) can be potentially considered as a raw material for unbleached pulp. In this study, unbleached pulp was produced from oil palm EFB by a pulping process with alkaline pretreatment. FT-IR analysis confirmed the presence of cellulose in the pulp, with absorption peaks at 3332 cm-1 corresponding to the O-H stretching and at 1029 cm-1 assigned to the stretching of the C-O-C bond, respectively. SEM images revealed the aspect of individual fibers, with a rigid appearance, in the pulp obtained from EFB biomass. The major crystalline peak was observed at 2θ of 22.41°, indicating the presence of cellulose. Brown paper was made from the unbleached pulp (A4 size, with a grammage of 134 g/m² and a thickness of 219.3 μm) and proved to have excellent mechanical strength. Therefore, unbleached pulp from oil palm EFB can be recommended to be used in the manufacture of brown paper. [ABSTRACT FROM AUTHOR]

Purpose: This paper aimed to review globally the empowerment programs for the prevention and control of smoking behavior among youths, to examine the role of empowerment in health promotion, to explore the stages of health promotion through community empowerment strategies including planning, implementation and evaluation. Finally, this paper will develop a model of youth empowerment to prevent and control smoking behavior that reflects theory and experience drawn from the literature. Design/methodology/approach: This review synthesized articles on community empowerment and health promotion, youth empowerment programs for tobacco prevention and control globally from books and electronic databases from the Universitas Gadjah Mada (UGM) library in the publication period 2000-2020. Relevant literature was selected and critically reviewed which reflected the role empowerment in health promotion, stage of community empowerment strategy as described by Laverack and youth empowerment concept in tobacco control as described by Holden. Findings: Documents that specifically discuss empowerment programs for smoking prevention and control are still limited. The findings document that youth empowerment in tobacco control do not fully integrate the theory empowerment as described by Laverack and Holden. This paper provides information about the stages of youth empowerment, and a conceptual framework of youth empowerment for the prevention and control of smoking behavior. Youth empowerment is done through the direct involvement of youth in programs starting from program design, planning, implementation and evaluation. Indicators of the success of the empowerment process are reflected in the increase in the empowerment domain. Meanwhile, the output of empowerment can be seen from the individual- or group-level changes. Originality/value: This paper proposes a model of youth empowerment for the prevention and control of smoking behavior among youths based on theory and experience in the field.

This study is meant to examine the thesis quality of students of English Department at IAIN Samarinda. Through the descriptive-quantitative research, the thesis quality of students of English Department at IAIN Samarinda is reviewed from the aspects of language, structure, concepts understanding, theoretical framework, methodology, content, writing mechanism, and references used. This study also tries to figure out any factors that affect the thesis quality of English Department students. Fourteen English Department Students' thesis tested in 2013 are used as the main data. In addition, other data are obtained from respondents i.e. 19 students, and informants i.e. lecturers of English Department who are also their thesis advisors. The result shows that the average score of thesis written by 14 English Department students at IAIN Samarinda academic year of 2013 is 3.16 which is in the range of 2.61-3.40 scale, which is quite good quality. This quality is relevant with the informants' perceptions about the quality of thesis written by their students. Judging from some aspects, they assume that their students are able to write a good quality of thesis with an average score of 2.81 which is at a scale of 2.61-3.40. The quality is affected by internal factors and external factors. The most decisive internal factor is the respondents' low score of writing with appropriate and acceptable structure in English. This is the effect of respondents' lack of ability of composing adequate paragraphs in English. Meanwhile, the most concerning external factor is the quality of learning structure course and the professionalism of the informants in guiding the students to improve their writing ability in thesis writing. A bibliography is included.

This study aimed to compare the accuracy of the test scores as results of Test of English Proficiency (TOEP) based on paper and pencil test (PPT) versus computer-based test (CBT). Using the participants' responses to the PPT documented from 2008-2010 and data of CBT TOEP documented in 2013-2014 on the sets of 1A, 2A, and 3A for the Listening and Reading section, the researcher estimated the reliability estimation results using classical test theory and the value of information function and on the item response theory on PPT are then compared with CBT, which has the greater reliability and the value of information functions is said to be more accurate. The study shows that with the classical test theory approach, the reliability coefficients between the scores of the results of PPT and those of CBT are almost the same, and using the item response theory, it was found that although the value of the information function on PPT and CBT are relatively similar in several subtests, there is a tendency for participants with the moderate ability that CBT is more accurate than PPT, and for the low and high ability of participants, PPT tends to be more accurate than CBT.

Among three sections that follow the Paper-Based TOEFL (PBT), many test takers find listening comprehension section is the most difficult. Thus, in this research the researcher aims to explore how students learn PBT's listening comprehension section effectively through song technique. This sounds like a more interesting and engaging way to learn language because music is a very powerful motivational tool for learning language. To reach the goal of this study, the researcher applied the grammar approach. It is an appropriate approach since the main idea of grammar-based listening exercises is to analyze the language by its components and reconstruct an incomplete text. Besides, the researcher employed an English song as the media the researcher uses the top-down model for the Listening Process. In this research, the writer tries to share his experience in teaching listening in English department of Teknokrat College by implementing song technique

This research employs critical discourse analysis (CDA) to examine a news article titled "KPU Chief Rebuffs Allegations of Bias during VP Debate" from the Jakarta Post, focusing on the transition from print to online media or E-Paper. In this research, the two main methods used to collect data are documentation via the Jakarta Post e-paper news page and content review. This approach provides the advantage of exploring information in depth and comprehensively related to the phenomenon or event that is the focus of the research. Utilizing Teun A. van Dijk's CDA framework, the analysis encompasses macro, superstructure, and micro structures. The macro-structural analysis reveals the social and political context, identifying social groups and emphasizing narrative importance. The critical discourse superstructure analysis delves into linguistic patterns, representations of power, and strategic language use. Finally, the micro-structural analysis explores word choice, grammar, writing style, and sentence structure to understand how language constructs arguments and responds to accusations. Through these lenses, the study provides a comprehensive understanding of how the news shapes and reflects social and political dynamics, contributing valuable insights into media discourse surrounding political events in Indonesia.

Anthraquinone has been widely utilized in the pulp and paper industry as a catalyst for alkaline cooking; however, its application has been recently restricted due to its potential carcinogenic effects. Hence, safer alternatives to anthraquinone have been explored. Agro-industrial by-products have been utilized as sustainable sources of value-added materials. In this study, teak (Tectona grandis) wood waste from Gunung Kidul, Indonesia, which naturally contains lapachol, was utilized as a biocatalyst to enhance delignification and improve pulp yield in alkaline cooking for pulp and paper production. The use of lapachol as a cooking catalyst was investigated for kraft, soda, and prehydrolysis soda cooking. Lapachol accelerated delignification and retained carbohydrate in all three alkaline cooking methods, with its effect being more pronounced in kraft cooking than in soda cooking. This study demonstrates that teak wood extractives with lapachol are promising sustainable catalysts for alkaline cooking. [ABSTRACT FROM AUTHOR]

Indonesian municipal solid waste (MSW) is dominated by biodegradable MSW (organic and paper). Due to the degradation process, the physical and hydraulic characteristics of these components can change. It is important to study the physical and hydraulic characteristics of MSW, because landslides occurred in several landfills in Indonesia after heavy rains. Field observations showed that landslides occur due to reduced paper components in the landfill (due to high recycling activities), and cause high percolation of water into the landfill. In the research, 38 samples consisting of two variants of MSW samples (organic and 80% organic + 20% paper), were prepared under the conditions of optimum moisture content. The organic sample of MSW is leaf, while the paper sample of MSW is newspaper, which were shredded to a diameter of about 1 cm. The tests of moisture content, bulk density (in the mould of permeameter), particle size distribution, and permeability were carried out on both sample variants for 90 days, with a test frequency of once in 5 days. The results showed that there was an increase in the moisture content and density, and a decrease in particle size and permeability in both variants of MSW sample. Organic MSW + paper has lower permeability and higher density than organic MSW. This requires further study, because a high paper recycling ratio can lead to a change in the landfill characteristics.

Indonesia is an emerging economy with a fast-growing digital sector. However, the development is not uniform across the country, with wide gaps related to regional differences and personal characteristics. This paper analyses the digital gap in Indonesia in the intersectional framework. I consider several metrics, such as the ratio of the population accessing the Internet, villages receiving mobile internet signal, and telecommunication expenditures. The study spans five years, from 2018 to 2022 (with some years missing for some of the variables). The data comes from BPS-Statistics Indonesia 2022 report "Telecommunication Statistics in Indonesia". I compute the Equality Ratios for one-dimensional and intersectional inequality as the value of the digitalisation metric for the most underprivileged group divided by the value for the most privileged group. Then, I assess the intersectional surplus as the difference between the inequality experienced by the intersectional group and the combination of one-dimensional inequalities. There is a substantial gap in internet usage and mobile internet availability in Indonesia, mostly related to urban/rural division and disparities between provinces. On the contrary, the gender gap is minimal. I also find no inequality in telecommunication expenditures. The gaps in internet usage were converging in recent years, but this was not true for the gaps in internet availability. People in intersectional groups face the combination of one-dimensional inequalities, but in most cases, there are none or minimal surplus effects. [ABSTRACT FROM AUTHOR]

Our dependency on wood has reduced the number of forests, especially in Indonesia. Hence, many people tried to use another material as a replacement for wood. One of them is composite. Department of Industrial Engineering Universitas Sebelas Maret has developed paperbased composite using newspaper waste in Praktikum Perancangan Teknik Industri (PPTI) II. Unfortunately, the quality of the composite is not so good. Some of the composites are broken when dried up below the sunlight, so we have to do some reworks. Besides, based on historical data, the average tensile, bending, and impact strength of composites in the last practicum are 0, 42 N/mm2, 2,68 N/mm2, and 0,0203 J/mm2. It is still below the Indonesian National Standard (SNI) of particleboard. This paper tried to understand the effect of factors on responses and discover the best combination of factors to obtain the best responses. The responses of this experiment are tensile strength, bending strength and impact value. The factors of this experiment are paper pulp, PVAc glue and water. Taguchi method is used to find the appropriate orthogonal array and Particle Swarm Optimization method to find the optimum combination of the factors. The orthogonal array used in this experiment is L9 (34). Through analysis, all of the factors are significant to tensile and bending strength, but they are not significant to impact value. The best combination of factors is 175 grams paper pulp, 130 grams PVAc glue and 175 ml water. Optimum results obtained for tensile strength of 0.7595 N/mm2 and bending strength of 4.8411 N/mm2.

The existence of Gardu Toll Otomatis (GTO), automatic toll payment, becomes a general model for every toll payment in Indonesia. Almost toll payment models in Indonesia have a paper printout as received which is often wasted. This condition happens since not all the driver needs a paper proof of the transaction. Therefore, the wasted paper will occur everywhere for 24 h. Furthermore, in this work the design of printout system using a more efficient printout model with rotation feeding method has developed printout system. In this work, the rotation mechanism system is applied through product design engineering through Industry 4.0. This system is made by removing the printout paper that remains present to the driver who needs it, but not wasted because of the driver who does not need it. There are three important steps as follows; in the first step, the printout paper appears in a special tray which is easy to reach and takes for those who need it. In the second step, the paper will remain in the tray for the driver who did not pick it up and final step, the tray with paper printout will rotate mechanically back into the GTO machine to be destroyed by a paper shredder. The experiment of the paper printout system has been carried out. The results show that the proposed approach produces a better accuracy and efficiency. Experimental results show the testing accuracy of 90%. The system confirms the effectiveness of the proposed paper printout system for the GTO. [ABSTRACT FROM AUTHOR]

The increasing use of recycled paper by the paper industry to support the Green Industry in the Indonesian Pulp and Paper Industry. But technically, there are some disadvantages of recycled fiber usage such as low drainage rate in which boosted the high energy consumption on drying process. As already known, the drying process consumes the highest energy in papermaking. To overcome this problem, the research using the concentrate of endoglucanase Egl-II has done. The steps of research included production of endoglucanase Egl-II; concentration by ultrafiltration method, modification of recycled paper fibers using endoglucanase Egl-II; characterization of paper sheet; and evaluation of energy consumption in drying the sheet of paper. The results showed that endoglucanase Egl-II had increase drainage rate of recycled fiber stock, which indicate by the freeness number. The number had increased by 80 ml CSF (Canadian Standard Freeness) from 190 ml CSF to 270 ml CSF, and fiber retention increased by 0,63% from 99,31% to 99,94%. The dissolved cellobiose test results of recycled fiber stock by the enzyme treatment at low dosage showed that no degradation of cellulose, no change into soluble sugars. Characterization of sheet of paper that has been modified with endoglucanase Egl-II based FTIR spectra showed no change in functional group, SEM results showed on the fiber surface fibrils grow more, and the results of the XRD analysis showed area reduction of amorphous regions is about 6%. The potential for energy efficiency is calculated through thermodynamic approach is about 15%. [ABSTRACT FROM AUTHOR]

Cheating behaviour in exams in the form of plagiarism occurs in school and college education. Academic fraud is common at the higher education level at the undergraduate, master's level, and even at the doctoral level. Academic fraud is getting out of control and is difficult to eradicate on examinations carried out online without strict supervision. The purpose of this research was to reveal the level of academic cheating in the form of plagiarism and its correlation with the results of the mid and final test of the Doctoral program, which was conducted in the form of an on-line take-home examination. This research use a correlation analysis technique with a simple regression test. The sample was determined by purposive sampling technique, amounting to 101 students of 2018, 2019, and 2020 classes who took the 2nd-semester learning technical analysis and development courses. The plagiarism level of the mid and final-semester results was tested using Turnitin. This research found that the level of plagiarism in the form of an average similarity index in the mid-semester are at the intermediate level; medium level internet resources; publication at a low level; and middle-level student papers. Meanwhile, at the end of the semester, it is known that the similarity index is at the intermediate level; medium level internet resources; low level publications, and student papers at the intermediate level. Furthermore, the results of this study also reveal that there is a positive and significant correlation between index, internet source, and student papers with the results of mid-semester exams, except for the source of publication plagiarism. Meanwhile, there is only a positive and significant correlation between the source of student paper plagiarism and the examination of the results for the final semester exams. In contrast, the similarity index, internet sources, and publication did not find a significant relationship.

This study aims to explore the correlation between students' digital competence and indecision with the challenges they encounter during the online scientific writing assistance process amid the Covid-19 pandemic. Students faced multiple forms of hesitation, communication breakdowns, and missed opportunities for discussion during this process. The research findings target guidelines for writing scientific papers. Qualitative data was collected through an online survey of 100 students from public universities in Indonesia. The research instrument employed an online questionnaire distributed to students via the Google Forms application. Data analysis was conducted using qualitative and interpretive approaches based on the principles of content analysis. The results revealed that students experienced profound doubts and confusion when it came to organizing their thoughts while conducting research and writing scientific papers as final projects. This research suggests that students' digital intelligence alone is insufficient for accessing the information required by their intellectual intelligence in writing scientific papers.

Microplastics in domestic wastewater are detrimental to living organisms and appear in a variety of sizes, colors, and shapes. The purpose of this study is to examine the distribution of microplastics in domestic wastewater, as well as the possibility for microplastic removal in wastewater treatment plants (WWTP). The sampling method used is SNI 6989.59:2008 concerning Wastewater Sampling Methods that Apply in Indonesia. To remove organic compounds in the sample, 0.05 M Fe (II) and 30% H2O2 solution were added by the digestion process at 75 ℃ for 30 minutes and cooled. Samples were filtered using Whattman GF/C filter paper with the help of a vacuum pump and dried. To identify the concentration, shape, size, color of microplastics, visual analysis was used with the help of a microscope using the zig-zag technique. The concentration of microplastics in domestic wastewater in Gampong Garot is 30.17 ± 0.75 particles/100 mL sample. The most commonly found microplastic size is 1,001-5,000 μm, while the dominant color is transparent. The forms of microplastic found in the samples were fiber, fragments and microbeads with a percentage of 65.20%, 23.16% and 11.64%, respectively. These microplastics come from local community activities such as washing clothes, bathing, washing dishes, and other activities. So, it is necessary to treat domestic wastewater using WWTP. Not only does it remove organic matter and nutrients, WWTP also has the potential of microplastics removal around 7-99% depending on the processing unit. [ABSTRACT FROM AUTHOR]

Research in legislative drafting in Indonesia is compulsory. Output of the research is academic paper (Naskah Akademik) which supports rationale needed for legislative drafting. This academic paper also provides logical and objective argumentation on significance of legislation. Even though research in legislative drafting has become a compulsory since 2011, academics and practitioners found several weaknesses in research methodology. This article discusses two major issues related to research methodology in legislative drafting (developing the academic analysis). The first is dynamics of legislative policy developments related to research methodology for developing academic paper for legislative drafting in Indonesia. The second is weaknesses of legislative policy developments related to research methodology for legislative drafting in Indonesia. This article shows that the national policy on legislation did not provide comprehensive guidance on research methods for developing academic paper for legislative drafting. The existing guideline discussed general issues, which affect quality of academic paper for legislative drafting. As an addition, academic paper for legislative drafting is treated as not more than complementary document for the drafting because it provided neither scientific justification nor arguments.

Refuse derived fuel (RDF) is an environmentally friendly renewable fuel developed to reduce waste generation. RDF can consist of various kinds of waste such as paper and gardens. One of the critical parameters is the chemical element and calorific value. The purpose of this study was to determine the potential for waste reduction and the relationship of ultimate longevity in RDF to the calorific value. This study's paper and garden waste mixture were P0 (100% paper), P25 (75% paper and 25% garden), P50 (50% paper and 50% garden), P75 (25% paper and 75% garden), and P100 (100% garden). The calorific value of the mixture can reach 3.6-5.2 kWh/kg. Simultaneously the relationship of ultimate elements nitrogen (N), hydrogen (H), oxygen (O), and ash affects the heating value of RDF. Sampling the application in Depok City can reduce waste by 6.67%, with the potential for electrical energy from paper and garden wastes of 358,903.8 kWh and 48,681 kWh, respectively. This shows that this energy waste can supply 0.1% of the total daily electricity demand in Depok City. [ABSTRACT FROM AUTHOR]

The aim of this study was to clarify the anatomical characteristics and predicted paper quality of Eucalyptus urophylla, E. grandis, and E. pellita planted in North Sumatra, Indonesia. In addition, potential hybridization among the three species was explored. The anatomical characteristics of the fiber (length, diameter, and wall thickness), vessels (element length, diameter, and frequency), the proportions of cell types, and the derived wood properties related to pulp and paper quality were examined for these three 9-year-old Eucalyptus species. The obtained results showed that vessel element length as well as fiber and ray parenchyma proportions significantly differed among the three species. Higher fiber and lower ray parenchyma proportions were observed in E. grandis, indicating that this species would be the best mother tree in a hybridization program for pulp and paper utilization, with the other two species complementary for refining the paper quality through this program. In terms of derived wood properties, the three species were considered to be promising raw material for the pulp and paper industry compared to other species that are broadly used as raw material for high-grade pulp and paper-based products.

The paper conceptualises digital technology as a source of innovation in value co-creation (VCC) at the bottom of pyramid (BOP) markets through fieldwork focused on vegetable supply chains in Indonesia. An inductive analysis based uponin-depth, semi-structured interviews with multiple business actors identified VCC in an emerging e-commerce channel where digital technologies enabled engagement and interaction amongst channel members. The results suggest that market scripting based upon an inclusive, collaborative and empowerment ideology, which can lead to sustainable development and income redistribution from consumers to producers, was explicitly embedded in their VCC agenda. Fair-trade practices supported customer-driven innovations. For consumers, digital technologies created online 'consumption communities' where information and educational interactions supported online food purchases and innovation in the supply chain 'pull' strategies. The paper concludes that the logic underpinning this new transformative business approach of digitally enabled VCC in local BOP markets is akin to a 'social justice logic'. [ABSTRACT FROM AUTHOR]

Traditional herbal medicine in Indonesia is still in great demand and popular in society. The Indonesian government regulations state that herbal medicine should not contain chemical drug due to the toxic effect of uncontrolled consumption. Allopurinol is one of the drugs commonly added to herbal medicine for the treatment of chronic gout. Paper-based analytical device is one of the latest forms of analysis that has been widely used for the identification of chemical elements, environmental contamination, bacteria, and many more. In this study, experiments were conducted using Whatman filter paper No. 1, No. 2, and No. 4 and Whatman chromatography as a paper, and 9 colorimetric reagents were tested for allopurinol detection in herbal medicine. There were 5 specific reagents that reacted positively with allopurinol and only 3 reagents that can be applied to the paper, that is, Folin-Ciocalteu, Tollens, and p-DAB reagent. The results of the optimization show that the most optimal immersion time was 60 minutes with a drying time of 30 minutes at 50°C. Each filter paper has different characteristic; however, there was no significant difference when all of the papers were used as PAD for allopurinol detection. [ABSTRACT FROM AUTHOR]

In this paper the dynamics of technological change and technical efficiency in the Indonesian pulp and paper industry are analysed. The industry is characterised by rapid growth of output and capacity, with some mills investing heavily in state-of-the-art machinery after 1984. Using stochastic frontier analysis, we distinguish between technological advances of best practice mills and the rate of technological inefficiency. We use a newly constructed micro-level dataset describing the complete population of Indonesian paper mills and paper machines from 1975 to 1997. We find an increasing divergence in technical efficiency over time, indicating that most plants have been not able to keep up with the technological leaders in the industry. Several of the plants operating the latest technologies have lower levels of efficiency than mills operating more outdated equipment. These outcomes qualify the common understanding of dualistic economic structures in developing countries, composed of less efficient traditional and more efficient modern capital intensive establishments.

Purpose: The purpose of this paper is to indicate the current state of studies on Islamic finance and management through a bibliometric analysis of the only social science citation index (SSCI)-indexed journal in this field. Design/methodology/approach: The paper uses a bibliometric analysis, collecting data from the 319 papers published in the International Journal of Islamic and Middle Eastern Finance and Management (IMEFM) from 2008 to 2019. Moreover, VOSviewer software has been used to illustrate the citation analysis (including most cited papers, most cited authors and authors' affiliated institutions and countries) and the keyword map. Findings: The number of papers published in each issue of the IMEFM is found to have significantly increased owing to its unique situation being the only SSCI-indexed journal in this domain. The share of the empirical researches in total papers published annually has steadily risen, reaching 95% in 2019. In terms of case countries, although Malaysia is the most examined country in the papers, other countries such as Indonesia and Turkey are found to have been used as a case country by researchers recently. Islamic banking-related papers are the most prevalent studies, as expected, with mainly their performance being examined. Meanwhile, the number of papers about Islamic social financial institutions has notably grown in recent years. Finally, technology-based initiatives such as crowdfunding and cryptocurrencies are noted to have not yet been the subject of any paper. Originality/value: The main contribution of this study is its analysis of the only SSCI-indexed journal on Islamic finance and management using bibliometrics. Also, all the papers published in the journal have been reviewed in terms of methodology, case country/country groups and topics/subtopics to lead the way for future research. [ABSTRACT FROM AUTHOR]

This paper examines community, environmental, and human rights activists’ influence on adoption of environmentally-friendly technologies in Indonesia’s pulp and paper industry. The story begins with conflict over the development of an export pulp mill in North Sumatra in the 1980s and continues with the adoption of environmental technologies in Indonesia’s pulp and paper industry in the 1990s. Organising around a number of specific events associated with pulp industry development, activists drew attention to the industry which led to a strengthening of government environmental regulation and enforcement, and hastened the adoption of cleaner production technologies.

The trade business license certificate (SIUP) is a paper-based license to conduct trade businesses in Indonesia issued by the government. Until today, there is no mechanism for verifying the validity of document unless to verify it manually. The current paper presents a design that allows paperbased verification of the printed trade business license. It aims to provide the verification mechanism and ensure the document validity. Our design implemented digital signature with QR Code image that placed into the document and the digital certificate issued by a certification authority (CA). The proposed scheme generated 442 Bytes of data and version 14 of QR Code to scan easily by a reader device. The experimental result indicates that our scheme is easy and feasible to implement in Indonesia with guaranteed the document integrity, authentication, and nonrepudiation. [ABSTRACT FROM AUTHOR]

Teachers as professionals play an essential role in the 21st Century in achieving the vision of national education. Teachers in the 21st Century must continue to improve their academic responsibilities, including writing scientific papers. However, the fact is that teacher activities are still focused on teaching and neglect scientific writing. Therefore, there must be an effort to explore their difficulties in writing. For this reason, this descriptive qualitative research aims to explore the difficulties of teachers in writing scientific papers identified through training activities. The research subjects were teachers of Madrasah Aliyah Negeri 2 Manggarai Ruteng, Indonesia (n=20). We followed a method of using a data collection process that includes document analysis, participatory observation, and focus group discussions. As a result of our research, we mapped the difficulties of teachers. Ongoing training, adding to the library collection, controlling and monitoring the implementation of Madrasah teacher working groups' activities, and mentoring experts need to be considered to support Madrasah teachers' professionalism. This finding has implications for applying a managerial reward and punishment pattern to increase teachers' motivation and interest in writing scientific papers. [ABSTRACT FROM AUTHOR]

This paper contributes to the debate on the role of technical change and industrial policy in Indonesian economic growth using the pulp and paper industry as a case study. The analysis indicates that industry and trade policies had a positive influence on growth and capital accumulation, but gave Indonesian pulp and paper companies few incentives to create or deepen their technological capabilities, resulting in fragmented and limited technology assimilation. The findings also raise questions about common interpretations of total factor productivity growth in Indonesia in terms of inspiration versus perspiration. [ABSTRACT FROM AUTHOR]

In the face of escalating global energy demands, the construction and management of pier infrastructure emerge as pivotal challenges, particularly for energy companies like Pertamina Patra Niaga in Indonesia. This paper aims to optimize pier construction management through the implementation of an OmniClass Work Breakdown Structure (WBS), addressing the critical need for standardized project management methodologies in complex, large-scale construction projects. By integrating a multidimensional WBS approach, akin to the hypercube or tesseract model, this study explores the enhancement of project planning, execution, and management. Employing a comprehensive literature review and case study analysis, the research investigates the efficacy of OmniClass WBS in facilitating better project coordination, cost estimation, and risk management. The findings underscore the significant advantages of adopting a standardized, multidimensional WBS, including improved data management and project outcome predictability. This paper concludes that the OmniClass WBS framework not only optimizes pier construction projects but also serves as a model for future infrastructure development endeavors within the energy sector [ABSTRACT FROM AUTHOR]

Abstract: Using the Kobe earthquake of 1995 and the Mid-Java earthquake of 2006 as case studies, this paper discusses the process of providing cultural recovery assistance; it also analyses the term ‘civil society’, a term that reflects efforts to make assistance activities sustainable. The Kobe earthquake should be seen as a point of departure for citizen activism by volunteers; because of it, cultural recovery support was vigorously provided. Since people influenced by those support efforts later became involved in providing Mid-Java earthquake recovery assistance, both earthquake recovery support initiatives can be seen as part of an ongoing chain of events. In analysing the Kobe earthquake, it becomes clear that while there are many semantic meanings for and usages of the term ‘civil society’, it was incorporated into policy guidelines for recovery during a period of low economic growth, and a new civil society was envisioned in this period of social transformation. Organisations participating in assistance efforts following the Mid-Java earthquake sought to make ‘civil society’ a reality; this continued after the earthquake recovery was complete, and it comprised an attempt to build the connections within a civil society by looking to overcome many persistent social problems. The power of communication that ‘culture’ holds plays a large role in this. [ABSTRACT FROM AUTHOR]
