The increasing population and anthropogenic activities in cities/regencies in Indonesia have caused many waste-related problems, which can trigger environmental and human health. In addition to population growth, rapid economic development has resulted in an increasing amount and type of waste. The coastal area is one area that still needs to get adequate solid waste services. There have been many studies on waste management. However, research has yet to examine the amount and composition of waste generation in coastal areas that have not been served by waste management.. This study shows the waste generation and composition trend in coastal areas that must be served in waste management and determines the appropriate waste management strategy. This research method uses a transect walk survey carried out by following a predetermined route in the area. Paths are made randomly by forming circles or straight lines for 10 km. The composition of illegal waste dumps found included leaves (69.02%), plastic (15.24%), branches and twigs (9.93%), paper and cardboard (3.75%), food waste (1.97%), and rubber (0.1%). At least 1.59 tonnes/day of illegal waste is estimated in Sidorejo Village. While this figure increases at the district level, the amount of unaccommodated waste is estimated at 19.85 tonnes/day. Efforts to handle waste that can be done are changing the mindset and paradigm of the community through an educational approach, improving the waste management system by providing waste facilities and reducing the amount of waste collected through a simple program (Reuses, Reduces, Recycle) that involves the community.

The Landoh landfillwas expired in 2022 due to the increasing amount of waste generated. The solution is to extend the service life of the landfill using the landfill mining method. The waste in the landfill is used as raw material for refuse derived fuel (RDF). The aim of the research is to find out the potential of landfill mining at Landoh landfillwhether it can be used as raw material for RDF. Primary data was taken from Landoh landfill in February 2022 with a depth of 1-2 meters and 3-4 meters from the surface of the waste generation and interviews with landfill officials. The waste samples were analyzed for waste composition, moisture content, volatile content, ash content and heating content. The waste composition is dominated by organic waste which has a large moisture content but a small caloric content. From the results of the research that the waste needs to be pre-treated (chopping and drying) for 21 days in order to fulfil the standard values of moisture content, volatile content, ash content and calorific content according to RDF raw material requirements. This method is a solution to overcoming expired landfills, reducing the volume of waste and landfill area requairements.

Eutrophication is a natural phenomenon in aquatic ecosystems that causes algae and other aquatic plants to overproduce. This process can benefit the ecology in tiny amounts, but too many nutrients can generate hazardous algal blooms and kill fish and other aquatic life. To prevent eutrophication and sustain aquatic ecosystems, agricultural waste water like microalgae production wastewater must be treated. The goal of the project is to get nitrogen and phosphorus out of the wastewater from growing microalgae, which is an agricultural waste water. One way to recover nutrients from wastewater is electrocoagulation. This procedure uses an electric current to create microscopic gas bubbles that collect and remove pollutants from wastewater. According to this study, electrocoagulation reduces phosphate and nitrate in microalgae culture wastewater. Phosphate concentration dropped by 90.20% in the 15th minute, while nitrate concentration dropped by 36.19% in the 30th minute. These reductions may be caused by struvite formation and nitrate conversion to nitrogen gas. This study demonstrates that electrocoagulation is a potential technology for recovering nutrients from agricultural waste water and reducing aquatic ecosystem eutrophication.

The success of the Marine Corps organization depends on the ability of its personnel to respond positively and overcome environmental challenges, acquire the new required skills, take official orders assiduously, and exhibit the adaptive performance from assigned tasks. Therefore, this study aims to analyze the adaptive performance model suitable for Marine Corps personnel by using job demands and crafting strategy as predictor and mediator variables, respectively. A quantitative method was used with cross-sectional and purposive sampling techniques. The model was tested using a sample of 230 Marine Intermediate Officers. The goodness of fit of the adaptive performance model is quite positive, with RMR = .05, CFI = .926, and TLI= .908. The results of the Structural Equation Model (SEM) analysis with AMOS 22 showed that: 1) the adaptive performance model offered for Marine Intermediate Officers is quite fit. 2) Job demands have a strong direct effect on adaptive performance. 3) Job crafting acts as a partial mediator between work demands and adaptive performance.

The role of the environment in business success is increasing from day to day. One of the ways to harmonize the goals of making a profit with the environment is by achieving green productivity. Green productivity means that companies can increase their productivity and at the same time improve their environmental performance. To reach that goal one of the ways is that businesses apply value stream mapping and make all the activities to be green which is known as a Green Value Stream Mapping. A combination of secondary data collection and Focus Group Discussions involving all relevant production staffs was conducted to get the initial data and the ideas to improve the performance of electricity, LPG, and water consumption at PT NIC Semarang. Compared to the initial data of the Current State Green Value Stream Mapping, the improvements resulted from the Future State Green Value Stream Mapping were a 51.4% decrease in electricity consumption, a 24.42% decrease in LPG consumption, and a 60% decrease in water consumption. From this empirical study, two important outcomes of future implications were found. For the food industry, implementing GVSM should be adjusted in such a way that the experiments to reach the Future State Green Value Stream Mapping will not affect the quality of the final products and that FGDs are very effective to generate ideas of improvements and getting commitments from production staffs to implement the improvements

Latar belakang: Perbedaan mekanisme remediasi elektrokinetik salah satunya disebabkan oleh distribusi gugus ≡SOH yang berbeda beda pada jenis lempung yang dapat mengontrol muatan permukaan lempung. Bentonit dan kaolin merupakan jenis lempung yang seringkali digunakan dalam penelitian remediasi elektrokinetik tanah terkontaminasi logam berat. Oleh karenanya, tujuan dari review jurnal ini adalah mengkaji perbandingan penggunaan kaolin dan bentonit dalam remediasi elektrokinetik tanah terkontaminasi logam berat, baik dalam publikasi penelitiannya, karakteristiknya dan pengaruhnya terhadap mekanisme remediasi elektrokinetik.Metode: Metode yang digunakan dalam review jurnal ini adalah systematic literature review, yang terdiri dari tahap identifikasi kata kunci, screening dokumen terpublikasi dan pemilihan jurnal berdasarkan kriteria-kriteria tertentu. Data base yang digunakan berasal dari Scopus, Science Direct dan Springer. Dokumen yang telah terpilih selanjutnya dianalisis dan dibandingkan. Hasil: Sebanyak 92% dari dokumen terpilih menggunakan kaolin dalam peneltian EKR, sedangkan 8% lainnya menggunakan bentonit. Berdasarkan karakteristiknya, bentonit memiliki daya adsorbsi yang lebih tinggi dari kaolin, namun, memiliki efisiensi penyisihan yang lebih rendah dari kaolin. Dalam pengaruhnya terhadap mekanisme remediasi elektrokinetik, arah aliran EOF kaolin maupun bentonit pada umumnya menuju katoda, namun bentonit dapat menyerap elektrolit lebih banyak dari kaolin, sehingga memiliki kadar air yang lebih tinggi. Sedangkan untuk konsumsi energi, remediasi elektrokinetik pada kaolin memerlukan energi yang lebih rendah dari bentonit.Simpulan: Bentonit dan kaolin memiliki perbedaan karakteristik pada kapasitas adsorbsi, efisiensi penyisihan logam berat, dan konsumsi energi. Meskipun arah aliran EOF pada bentonit dan kaolin sama, namun kapasitas penyerapan elektrolit pada bentonit lebih besar dari kaolin. ABSTRACTTitle: Research Study on the Use of Kaolin and Bentonite in Electrokinetic Remediation for Heavy Metal RemovalBackground: One of the differences in the electrokinetic remediation mechanism is caused by the distribution of different ≡SOH groups on the type of clay that can control the surface charge of the clay. Bentonite and kaolin are types of clay that are often used in the study of electrokinetic remediation of heavy metal contaminated soils. Therefore, the purpose of this journal review is to compare the use of kaolin and bentonite in the electrokinetic remediation of heavy metal contaminated soils, both in their research publications, their characteristics and their effect on the electrokinetic remediation mechanism. Method: The method used in this journal review is a systematic literature review consisting of keyword identification, screening published documents and selecting journals based on certain criteria. The database used comes from Scopus, Science Direct and Springer. The selected documents are then analyzed and compared.Result: As many as 92% of the selected documents used kaolin in the EKR study, while 8% used bentonite. Based on its characteristics, bentonite has a higher adsorption capacity than kaolin. However, it has a lower removal efficiency than kaolin. In its influence on the electrokinetic remediation mechanism, the flow direction of kaolin and bentonite EOF is generally towards the cathode, but bentonite can absorb more electrolytes than kaolin, so it has higher water content. As for energy consumption, electrokinetic remediation on kaolin requires lower energy than bentonite.Conclusion: Bentonite and kaolin have different characteristics in adsorption capacity, heavy metal removal efficiency, and energy consumption. Although the direction of EOF flow in bentonite and kaolin is the same, the electrolyte absorption capacity of bentonite is greater than that of kaolin.

Usually, the main source of water is a river, which makes it essential to ensure that the water from that source is not polluted and in accordance with the water quality standards. Water quality can deteriorate as a result of domestic and industrial waste. This quality is measured based on several parameters, such as the concentration of pH, nitrate, phosphate, and fecal coliform in the water. QUAL2KW can be used to analyze river water quality in order to solve several water quality-related problems. The main river water source in Semarang Regency is the Klampok River, whose water is used to support agriculture, livestock, and other activities. This study aims to determine the concentration of the above-mentioned parameters in the samples from the Klampok River using QUAL2KW. The water samples are obtained from different six points on the Klampok River, and the chi-square test is used for validation. From the laboratory test results for the river-quality parameters, after being simulated using QUAL2KW and validated using the chi-square method, it can be concluded that the quality of the Klampok River belongs to class II. These results can be used as a reference by the Semarang Regency government in managing river water quality.

Universitas Diponegoro has a role in contributing to considerable numbers of hazardous solid waste from academic activities as it is the largest university in Central Java Province, Indonesia. Therefore, improper hazardous solid waste will cause potential disease for humans and pollute the environment. For this reason, proper hazardous solid waste management is urgently needed. This research aims to design hazardous solid waste management for Universitas Diponegoro as a pilot testing study. The research used questionnaires, surveys, in-depth interviews, and observations to construct an appropriate hazardous waste management system. The result showed that hazardous solid waste in Universitas Diponegoro came from 5 sources: education, office, laboratory, supporting facilities, and Pleburan Campus. The estimation of hazardous solid waste produced by the Universitas Diponegoro in 2021 is as much as 100.4 kg/day. The hazardous waste characteristics are toxic, corrosive, flammable, and infectious. In the hazardous management planning that was developed, the design of the waste transportation and storage system at the waste station in the Tembalang and Pleburan campuses has a total investment and operation cost of Rp 6,259,841,999 for 10 years of operation. This design is hoped to enhance the campus's achievement in sustainability efforts.

In 2017-2019, the Tanah Laut Regency, Banjar Regency, Banjarbaru City population was relatively high and continued to increase every year. The increase in the population reaches 1.39% to 2.92%. Along with population growth, the human need for clean water also increases, especially from groundwater. The study aims to assess the vulnerability of groundwater to contamination. The method used for the analysis of groundwater vulnerability to contamination is the DRASTIC method. It refers to seven parameters, namely groundwater depth (D), net recharge (R), aquifer media (A), soil layer (S), topography (T), impact to vadose zone (I) and hydraulic conductivity (C) by using geospatial analysis to calculate the DRASTIC Index/DI. From the results of geospatial analysis, there are three zones of groundwater vulnerability to contamination based on DI values, namely low vulnerability (95-106), medium vulnerability (106-146), and high vulnerability (146-186). The distribution of high zones dominates in the research area around of 75, 8%. The DRASTIC method requires a lot of data to provide an accurate analysis of groundwater vulnerability zone maps. This method has excellent accuracy and more effective in producing a map of the groundwater vulnerability zones to contamination.

The addition of bentonite to fly ash can lower the permeability coefficient of the composite landfill liner. Also, the montmorillonite bentonite can bind quite a lot of water molecules during the hydration process. In this study, the effect of mixture, water content, and salinity on the desiccation cracking phenomenon in the bentonite - fly ash mixture as a landfill liner system was investigated by conducting tests such as desiccation test, water content test, and standard proctor and permeability test. The variation in bentonite levels: 0%, 15%, 20%,25% and 25% + 1 N NH4Cl solution. The result shows that the appropriate mixture is fly ash + 15% bentonite with permeability of 4,065 x 10-7. The mixture complies with local regulations where the permeability coefficient of the bottom layer of the landfill should be less than 10–6 cm/s and have a low cracking value (CIF). Furthermore, the addition of saline solution to the composite can rise the value of the optimum moisture content. However, saline conditions can decrease the value of CIF drastically

This study aims to compare the energy balance of the production of biodiesel from multiple feedstocks to the production of biodiesel from palm oil in Indonesia. The energy balance study indicates that the biodiesel multi-feedstock plant is feasible to operate. The renewability of biodiesel from multiple feedstocks is 3.31 and that of palm oil biodiesel is 6.23. It is due to the fact that the energy content and demand of multi-feedstock biodiesel are much lower than palm oil biodiesel. The energy content of biodiesel from multiple feedstocks (and its co-products) is less than that of biodiesel from palm oil (and its co-products), 109,041 MJ vs 130,370 MJ, respectively. The energy demands for the production of biodiesel from multiple feedstocks and biodiesel from palm oil are 35 × 103 MJ and 23 × 103 MJ, respectively. Energy demands, including fossil and biomass, are attributable to plantation operations, including the usage of fertilisers. Plantations of multiple crops use more energy than plantations of oil palm alone because they require more fertilisers. It is not suggested to produce multi-feedstock biodiesel from sunflower, canola, and soybean since its energy balance is not better than biodiesel from palm oil.

Religious nationalism is interpreted differently in its application in various countries. The purpose of this study is to explore the development of the meaning of religious nationalism values according to religious figures in Indonesia. The research method used to analyze social phenomena is a qualitative approach, using direct interviews and observations as the main data collection instruments. The essential results of this study are the values of religious nationalism must be preserved as a binder of social harmony since the formation of the Indonesian state. Religious figures view that the values of religious nationalism in Indonesia reject the secular state and the idea of an Islamic state (caliphate). The critical implication of this research is that religious figures promote the implementation of universal religious values in the public sphere and urge freedom of expression of religious activities democratically without discrimination for adherents of all religions.

Dewatered sludge is the main by-product from wastewater treatment and it contains various types of hazardous substances which can cause environmental pollution. The alternative utilization of sludge waste is for covering the landfill or as liner for the landfill. Landfill cover is a critical component to protect the surrounding environment from leachate contamination produced by landfills and it has specific characteristics. This study analyzes the optimum water content, permeability coefficient, and stability of the material consisting of a mixture of dewatered sludge, bentonite, and quicklime. The test results show that the optimum water content in the three composite variables meet the requirements; the highest optimum value was 28%, a mixture with a ratio of 84% sludge, 15% bentonite, and 1% quicklime. The results also show that mixing sewage sludge with bentonite significantly reduces the permeability value with a ratio of 80% sludge, and 20% bentonite produces the lowest permeability coefficient of 1.979 x 10-7 and this has reached the hydraulic conductivity limit of 1 x 10-7. The shear strength and safety factor results test show that V3 had the best results, with a cohesion value of 22.40 kPa, a shear angle of 31.97°, and a safety factor of 5.297. The addition of bentonite tends to reduce the value of the safety factor. This safety factor can reach a high value because of the ratio of the total shear resistance to the working soil shear stress.

The rainwater that reaches the ground will enters the soil (infiltration) and some water are not absorbed by the soil will become surface runoff. The regional development tends to change water catchment areas by changing land functions and affecting surface runoff. The regional development in Kalibenda Village has cause problems related to the local community water supply. In 2019 some of the local community in Kalibenda Village have experienced difficulties in accessing clean water supply which has never happened in the past . This study provides an analyze of the impact of land use changes that occur in Kalibenda Village on surface runoff. This study uses a Rational method to calculating runoff discharge by using elevation profile analysis tool from Google Earth program to calculated sloop, Approb_4.1 program to process rain data and ArcSwat Tools in the ArcMap 10.2 program to water catchment analysis. The study results shows that Kalibenda Village divided into 6 (six) catchment water. There has been increased runoff from 2000 to 2021 by 6.44%. The most influential factors are changes in land cover change from rice fields to settlements, plantations and meadow grass.

In Indonesia, transportation sector, specifically road transport consumed most energy compared to other sectors. Eventually, the energy consumption will increase due to the growth of vehicle number that also escalate emission. Vehicle emissions had been recognized as a significant contributor to atmospheric greenhouse gas (GHG) pollution. Heavy-duty vehicles are considered as main sources of vehicular emissions in most cities. Therefore, it is crucial to take into account heavy-duty vehicle emission projections in order to support policymakers to identify vehicle emissions and develop pollution control strategies. The aim of this study is to forecast heavy-duty vehicle population, vehicle kilometers travelled (VKT), fuel consumption, and heavy-duty vehicle emissions using data of Semarang City to illustrate greenhouse gas emission of big cities in Indonesia. Business as Usual (BAU) and The Intergovernmental Panel on Climate Change (IPCC) method were incorporated to determine vehicle emission projection. Heavy-duty vehicle emissions increase from 2021 to 2030 by 12.317 to 22.865 Gg CO2/year with amount trucks and buses emissions of 21.981,5 Gg CO2/year and 884,2 Gg CO2/year, respectively.

It is estimated that the amount of water needed by Universitas Diponegoro will increase in the years to come. Several efforts are required to ensure the fulfillment of water needed while also considering its sustainability. There have been studies on water conservation at the industrial level. Still, limited studies have discussed this problem in Indonesia specifically at university level. Therefore, this study discusses the water conservation program at Universitas Diponegoro that might be used as a reference for other universities to address water supply problems. This study aims to discuss in depth water conservation efforts at Universitas Diponegoro. This study incorporates a descriptive-qualitative approach along with direct observation. Some programs on water supply have been implemented in Universitas Diponegoro such as conservation, treated water consumed, water recycling and water-efficiency. The existence of rainwater harvesting tanks (RWH), reservoirs, biopores, wastewater treatment plans (WWTPs) and ponds are among the efforts that have been applied at Universitas Diponegoro in order to conserve the water. To date, Universitas Diponegoro has successfully conserved more than 75% of the water, recycling about >50% of wastewater, installing about >50% of water-saving equipment, and has treated clean water into drinking water using reverse osmosis.Keyword: water, conservation, sustainability, campus

Adaptive performance of Marine Corps’ Middle-Ranked Officers (Perwira Menengah Marinir) is an important indicator of the success of the Indonesian Marine Corps’s mission. High job demands and job resources indicate that the Marine Corps is a challenging organization. This study aims to provide a broader perspective on contextual antecedents of Marine Corps organization with job crafting as a mediator of job demands and job resources on the adaptive performance of Marine Corps’ Middle- Ranked Officers. This study used a quantitative approach with a questionnaire survey towards 230 Indonesian Marine Corps’ Middle-Ranked Officers. Data analysis were done using Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) with SPSS 22 and AMOS 5.0. Results shown that the hypothesis developed on this research study got significant support. Job demands had positive effects on adaptive performance (β = .16; p< .001); job demands had negative effects on job crafting (β = −.13, p< .01). In return, job resources had positive effects on adaptive performance (β = .59; p< .001) and job resources had positive effects on job crafting (β = .77, p< .001); job crafting had positive effects on adaptive performance (β = .39, p< .001). Effects mediated by job crafting showed a good fit, variance of the adaptive performance 80.9% and variance of job crafting 65.3%. In this case, job demands have a positive effect on the performance of Marine Corps’ Middle-Ranked Officers. Further details are explained and discussed.

Indigenous Trichoderma has widely used in late-blight epidemic areas in Magelang, Indonesia as biocontrol and biomodulator. But it application still lacks of scientific proof, even though it is potently to be developed. Therefore, this study aims to identify and evaluate indigenous Trichoderma application in eradicating late blight and increase productivity. This research was an experimental posttest-only using six experimental plots, with P0 plot with no treatment. The solution was made by dissolve indigenous Trichoderma solid-starter into water (m/v), then used for treatment. The treatment plots including: two groups of sprayed-only plots with doses of 100 g/ 10 L of solution for P1 and 150 g/ 10 L of solution for P2; and two group treated with sprayed-poured method using doses of 100 g/ 10 L of solution for P3 and 150 g/ 10 L of solution for P4. The positive control group was P5 group, treated using chemical pesticides and tuber booster. The microscopic identification revealed that the local bioagent was Trichoderma harzianum species. Application of T. harzianum in P4 was significantly increased the productivity. However, it was not effective in increasing growth, but able to reduce the intensity of late blight disease. The research revealed that native Trichoderma is able to be used as anti-infectious agent and potentially improve the quality of potato plants. In the future, this research may worthwhile for farmers to develop and produce trustworthy and proven Trichoderma -based biocontrol and help them increase the potato production economically.

Corporate failure suggests that weak corporate governance leads to frail institutions and exposes them to severe crises. Asian countries have faced financial crises in three different periods, most recently due to the COVID-19 pandemic. A crisis will trigger structural changes in corporate governance to enable firms to either respond to, or prevent, the reoccurrence of potentially similar events. The characteristic of corporate governance practice in Asian countries are also unique due to some institutional and informal factors. These will alter direction and future trend of research in corporate governance in Asian region. The objective of this study is to utilize a bibliometric analysis which focuses on research trends and themes, and citations (with additional inclusive visualization) and perform in-depth content analysis to trace the evolution and identify knowledge of corporate governance in Asian countries from 2001 to 2021. Following bibliometric analysis, a sample of 656 articles on corporate governance in Asian countries has been extracted and analyzed from the Scopus database. The results indicate that there is a growing of interest in corporate governance in Asian countries from 2001 to 2021. Eight major themes have been recognized: corporate governance, corporate social responsibility and financial performance, corporate strategy and performance, agency theory, corporate sustainability, audit and agency problems, firm size, and business ethics. Major findings, shortcomings, and directions for future research are also discussed in this study. In general, most cited articles related to corporate governance theme explain the importance of corporate governance in companies with the focus on preventing financial fraud, impact on earnings management, and cost of equity capital in the market and reporting methods.

In a developing country like Indonesia, waste management remains one of the main problems faced due to a lack of coordination between various stakeholders and budget limitations to implement advanced waste management methods. The Batang regency is no exception, where overall waste reduction and waste recycling percentage (out of total generated waste) are only 0.61% and 0.08% respectively. One of its villages, Kalisalak village, is a religious agritourism village that has a lot of economic potential in various sectors, with by-products that can be utilized and processed as various materials and resources to improve the local community and support sustainable development. Organic waste from Kalisalak village can be processed into organic fertilizers, eco-enzymes, takakura basket, and biopore infiltration hole, while plastic waste can be used as paving block materials. Non-domestic sawdust waste from non-domestic sectors can be processed into growing media for ornamental plants, horticulture, and edible mushrooms. Thorough field surveys are still needed for this study. urveys are still needed for this study.

Most traditional food industries in Indonesia are not complying with the expected environmental standard due to a lack of knowledge and environmental behaviour. Environmental damage in Sugihmanik, Purwodadi Regency, is one of the examples of the side effect of tofu industrial activities. At least 98,120 l of wastewater is disposed directly into the river daily. This manuscript presents the current situation of traditional tofu industries in Sugihmanik Village and analyses the most appropriate treatment design for tofu industrial wastewater. The descriptive method was used to identify the current practice to protect the environment. A hierarchical analytical process (AHP) was used to choose which wastewater treatment is suitable to be implemented there. This research also presents a practical method to identify the current flow of wastewater. The result shows that the wastewater produced by each tofu industry is 29.7 m3/ton of soybean used in the process, which less than the recent literature. AHP result also shows that up-flow anaerobic sludge bioreactor (UASB) has become the most appropriate wastewater treatment for the tofu industries.

This study has purposes calculating GHG emissions using the IPCC calculation methods (default) to estimate the potential for GHG emissions in the reduce, reuse, and recycle (3R) activities in integrated temporary waste storages (ITWSs), waste transportation, and the Jatibarang landfill. The results of this study indicate that the landfill activity has the greatest value of GHG emission potential compared with other activities. Optimization of 3R activities at the landfill site is also considered capable of reducing the GHG emissions of the existing waste by up to 75% without composting.

OBJECTIVE People with severe mental illness often have difficulty sustaining employment. Work Behaviour Inventory and Work Environment Impact Scale are vocational assessments used by occupational therapists to evaluate the facilitators and barriers of work performance and work environment respectively. These factors may have an impact on job tenure and can inform occupational therapy practice. METHODS This study analysed retrospective data of 85 clients who attended a 3-month Employment Internship Program from August 2016 to August 2017. Scores from Work Behaviour Inventory and Work Environment Impact Scale were analysed for associations with job tenure. Repeated measures were used to determine significant changes in Work Behaviour Inventory composite scores across the 3 months. RESULTS One-month Work Behaviour Inventory composite scores, three Work Behaviour Inventory domains (cooperativeness, work habits, work quality), and three Work Environment Impact Scale domains (time demands, supervisor interaction, architecture) were significantly associated with job tenure. Significant differences in mean job tenure were also found between participants of different internship status. However, these factors did not predict job tenure in regression analysis. There were significant improvements in Work behaviour Inventory composite scores from the first to third month. CONCLUSIONS Work behaviours such as cooperativeness, work habits, and work quality as well as work characteristics such as time demands, supervisor interaction, and workplace architecture may play a role in influencing job tenure. Occupational therapists may consider such factors and provide more targeted interventions to effectively sustain employment.

The number of companies in Indonesia that have participated in environmental-related activities continues to grow. Some of these companies have also engaged and implemented an assessment program called Program for Pollution Control, Evaluation, and Rating (PROPER). This assessment program was initially launched by the Indonesian Ministry of Environment in 1995 to measure and rate the environmental performance of companies in Indonesia. They have also administered an environmental management system as part of their environmental protection initiatives. However, the level of environmental disclosure by these companies is still low. This may occur due to the current situation in which the companies are not obliged to incorporate environmental disclosures on their annual reports. For those companies that disclose their environmental performance, there is also no apparent reason on why they have done that. This research aims to examine the effect of environmental performance, company financial performance, and company characteristics on environmental disclosure. The population used in this research comprised of all registered non-financial companies in the Indonesia Stock Exchange in 2014–2016. The sample was selected using a purposive sampling method to obtain 36 sample companies and analyzed through multiple regression analysis. Results show that the environmental performance variable, which is described by PROPER ratings and environmental management systems, and company size variable, both affect the extent of environmental disclosures. However, the financial performance variable, which is described by companies’ profitability and leverage, and the number of board commissioners variable, both do not significantly affect the extent of environmental disclosures.

Background: Diarrhea is still the second-largest cause of children under-five's mortality worldwide. Six million children die every year due to diarrhea and it mostly occurs in developing countries. The main cause of diarrhea deaths is due to malnutrition. In malnutrition there is an increase in the severity of diarrheal diseases, this makes malnutrition and diarrhea a vicious circle.Objective: To investigate the relation between nutritional status and length of stay under-five children with diarrheaMethod: A cross-sectional study was conducted from August 2018 to January 2019 using the consecutive sampling methods. The subjects were children aged 1-5 years old hospitalized for diarrhea at Wangaya Hospital Denpasar that fulfills the inclusion and exclusion criteria. The characteristics of the subject such as gender, children's age, birth weight, exclusive breastfeeding status, immunization status, degree of dehydration, mother’s employment, and economic factor.Result: A total of 42 patients were the subjects of the study. Of 10 subjects with wasted nutritional status, 7 (70%) subjects had long stays (> 4 days), and 3 (30%) others with a short length of stay (≤4 days). Most subjects aged 12-24 months were 52.4%. Most of the subjects were male (57.1%). The results of the analysis showed that nutritional status significantly affected the length of stay of diarrhea in children under five (p-value 0.001; PR 5.6; 95% CI 2.05-9.26).Conclusion: There is a significant relationship between nutritional status with the length of stay in children under five.

The rapid synthesis of zeolite thin film coating on metal surface was demonstrated for LTA, FAU, EMT, SOD, CAN and JBW on stainless steel. The direct heating of LTA-seeded stainless steel was achieved in a specially made synthesis reactor enabling rapid heat transfer that promote zeolite deposition and growth. Microns thick zeolite film can be grown on the stainless steel with an acceptable degree of intercrystalline defects in a relatively short crystallization time (i.e., 45 min). The type of zeolite deposited can be controlled from the starting composition of the synthesis mixture, the ageing time and substrate temperature enabling the preparation of both pure and mixed phase zeolites.

Background: Pneumonia is the leading cause of under five children’s mortality worldwide. In Indonesia, pneumonia still the second largest cause of mortality in infants (12.3%) and under five children (13.2%) after diarrhea. However, the incidence of pneumonia didn’t receive some attention so it’s often referred as “the forgotten killer of children”. Therefore, the aim of our study is to control pneumonia in children under five by investigating the risk factors of pneumonia.Methods: A case control study was conducted from January 2019 to May 2019 by using the consecutive sampling methods. The subjects were children aged 12-59 months old with pneumonia at Wangaya Hospital for the case and children aged 12-59 months old without pneumonia at Wangaya Hospital for the control. Subject’s characteristics such as gender, age, weight birth, immunization status, exclusive breastfeeding status, history of asthma, smoke exposure, and nutritional status. Matching was performed on exclusive breastfeeding variable. Will be done the bivariate analysis with McNemar and multivariate analysis with logistic regression.Result: Among 96 subjects divided into 48 subjects in each group. Bivariate analysis showed that immunization status (p-value 0.009, OR 5.209) and smoke exposure (p-value 0.008, OR 2.238) were the significant risk factors of pneumonia. While gender, nutritional status, and history of asthma weren’t significant risk factors of pneumonia in children under five at Wangaya Hospital.Conclusion: Incomplete immunization status and exposed to cigarette smoke are the risk factors of pneumonia in children aged 12-59 months old at Wangaya Hospital. Latar Belakang: Pneumonia merupakan pembunuh nomor satu balita di dunia. Di Indonesia, Pneumonia menduduki peringkat kedua penyebab kematian bayi (12,3%) dan balita (13,2%) setelah diare. Sayangnya, kejadian pneumonia tidak begitu banyak mendapat perhatian khusus. Tujuan penulisan laporan kasus ini adalah mempelajari faktor-faktor resiko yang menyebabkan pneumonia.Metode: Dengan menggunakan studi kasus-kontrol yang dilakukan pada bulan Januari 2019-Mei 2019 menggunakan metode sampel konsekutif. Subjek penelitian adalah anak berusia 12-59 bulan dengan pneumonia di RSUD Wangaya untuk kasus, dan anak berusia 12-59 bulan tidak dengan pneumonia di RSUD Wangaya untuk kontrol. Karakteristik subjek berupa jenis kelamin, usia, berat badan lahir, status ASI eksklusif, status imunisasi, riwayat asma, paparan asap, dan status gizi. Dilakukan matching pada variabel ASI eksklusif. Dan akan dilakukan analisis bivariat dengan uji McNemar dan multivariat dengan regresi logistik.Hasil: Sebanyak total 96 subjek, dengan 48 subjek untuk masing-masing kelompok penelitian. Didapatkan hasil yang signifikan pada faktor resiko status imunisasi (nilai p 0.009 dan OR 5.209) dan faktor resiko paparan asap (nilai p 0.008 dan OR 2.238). Sedangkan jenis kelamin, status gizi, dan riwayat asma tidak didapatkan hasil yang signifikan sebagai fakto resiko pneumonia di RSUD Wangaya.Simpulan: Status imunisasi yang tidak lengkap dan terpapar asap rokok merupakan faktor resiko terjadinya pneumonia pada anak usia 12-59 bulan di RSUD Wangaya.

The electrokinetic remediation method can function as a primary or secondary technology and can be applied in conjunction with other physical and biological methods, such as soil washing, phytoremediation, and bioremediation. Environmental impacts arising from the electrokinetic remediation process can be determined using life cycle assessment analysis (LCA) or other tools. This study compared the conventional electrokinetic remediation strategy with two hybrid strategies: electrokinetic-phytoremediation (EKR-Phyto) and electrokinetic-bioremediation (EKR-Bio). The environmental performance of the three strategies is then tested through LCA analysis. The database used was The Ecoinvent, and the freeware software used during the inventory stage was OpenLCA. The impact assessment stage was used in the Recipe I (2016) midpoints, Available Water Remaining (AWARE) midpoint, Intergovernmental Panel Climate Change (IPCC) midpoint (2003), UNEP Society of Environmental Toxicology (USEtox) midpoint, and cumulative energy demand midpoint. The significance of the analysis results was not obtained for the GWP parameter but for the freshwater eutrophication parameter. Among the three strategies, the EKR-Phyto strategy showed the highest significance in eutrophication but the lowest significance in land change. Substitution of chemical fertilizers into natural fertilizers in the EKR-Phyto strategy can be an opportunity for environmental sustainability. The highest impact for ecological analysis of the three strategies was EKR-Phyto in terms of GWP, the sum of primary energy, Acidification Potential (AP), and Photochemical Ozone Creation Potential (POCP).

Substitution of fossil fuel into alternative energy sources, such as biogas, needs to be applied to prevent various problems in the environment. Biogas purification can be an alternative technology to improve the quality of biogas, which increases the heat value by reducing CO2. Purification can be carried out by the adsorption method using solid adsorbents, for example natural zeolite and activated carbon. This study used 12 reactors from PVC, with 2 different diameters, 3 different mesh size (20,50,80) and was given both zeolite (A1-A3; B1-B3) and activated carbon (A4-A6; B4-B6). Biogas purification with the addition of zeolite has an optimal compound content in reactor A3 which has an increase in CH4 (63.63%) and decrease in CO2 composition (25.07%), which is better than other reactors. Meanwhile, the results of measurements of gas content on the addition of activated carbon showed optimal performance in reactor A6, which was increased to 76.86% for CH4 levels and CO2 levels dropped to 19.79%.
