Abstract Background Pathogenic microbes still become obstacles that can reduce the quality of plant growth, including ramie (Boehmeria nivea) plants. The study identified the microbiome and antagonistic interaction of the endophytic community from the B. nivea is necessary to improve the production of the ramie plant, especially ramie stem organs for fiber materials. Results Twenty isolates of endophytic microorganisms were obtained from the roots, stems, leaves, and flowers. They were identified using the Internal Transcribed Spacer (ITS) region of ribosomal (rDNA), and its morphotypes obtained 20 isolates, with a composition of 9 species of bacteria and 11 species of fungi. Besides that, the disease observations on ramie stems showed that four species of pathogenic fungi were identified as Fusarium solani isolate 3,248,941, Fusarium solani isolates colpat-359, Fusarium oxysporum isolate N-61–2, Clonostachys rosea strain B3042. The endophytic microorganism of ramie ability was tested to determine their potential to inhibit the growth of the pathogenic fungi based on the in-vivo antagonist test. The isolated bacteria were only able to inhibit the growth of F. solani, with the highest percentage of 54–55%. Three species of endophytic fungi, including Cladosporium tennissimum, Fusarium falciforme, and Penicillium citrinum, showed the best inhibition against the fungal pathogen Fusarium solani with the highest inhibitory presentation of 91–95%. Inhibitory interaction between the endophytic microbes and the ramie pathogens indicated the type of antibiosis, competition, and parasitism. Conclusion The results of this study succeeded in showing the potential antifungal by endophytic fungi from ramie against the pathogens of the plant itself. P. citrinum isolate MEBP0017 showed the highest inhibition against all the pathogens of the ramie.

The strength value of unweathered clay shale stacked beneath the soil surface is high. Clay shale will deform and lose its strength if exposed to the surface and changes in weather conditions due to brittleness caused by weathering. Thus, it would be dangerous if used as embankment material due to its sensitiveness. This study analyses the effect of adding propylene glycol and potassium chloride to weathered clay shale. Propylene glycol and potassium chloride are commonly used as a drilling fluid to prevent the degradation of the shale layer. They can increase the stability of clay shale by making it more durable when in contact with the wetting and drying process. The results from this study show that propylene glycol, added to clay shale, can increase the value of soaked CBR to twice the initial value and decrease the swelling percentage. Adding potassium chloride to the clay shale can also increase the value of soaked CBR to twice the initial value and reduce the swelling percentage. However, the combination of Propylene glycol and potassium chloride cannot increase the value of soaked CBR and could even shrink the sample and reduce the optimum water content.

Mathematical communication is crucial in inclusive mathematics teaching and learning to convey mathematical symbols. However, teaching mathematical symbols to deaf students in inclusive classrooms has been a persistent challenge due to the lack of specialized sign language for mathematical expressions. Media, such as SPECOMATSO technology, can serve as a bridge to address this issue. This research focused on developing valid and practical SPECOMATSO technology to strengthen students’ literacy and facilitate the delivery of mathematical symbols, which previously posed difficulties for teachers in inclusive settings. The research combined the Alessi & Trollip and V-waterfall models, encompassing seven development stages: analysis, design, implementation, unit testing, integration testing, system testing, and acceptance testing. The research instruments included observation and interview guidelines, a product validation questionnaire, and a student response questionnaire. This study produces SPECOMATSO technology that is valid and practical for learning plane geometry and angles in mathematics. Although this development still needs improvement in fixative abilities, such as storage and editing functions, it is expected to strengthen digital literacy and stimulate mathematical communication among deaf students who face challenges related to their limited auditory capabilities.

Foreign Language learning is a complex process that requires considerable effort from both teachers and learners, particularly in developing effective listening skills in foreign language classrooms. Among the various approaches, Extensive Listening (EL) has emerged as a promising pedagogical method for enhancing language acquisition. This research investigates the utilization of Extensive Listening (EL) as a pedagogical approach for teaching Arabic listening skills, focusing on its efficacy in facilitating vocabulary and grammar acquisition, as well as exploring students' perceptions regarding the benefits of language learning through EL. Language teachers often face challenges in cultivating listening skills among foreign language learners due to its inherent difficulty. The study employed observation, documentation, and focus group discussions as data collection methods, while data analysis involved several stages: data description, data reduction, and drawing conclusions. The findings reveal that EL was effectively integrated into the Arabic listening course, aligning with the course objectives and learning materials. Students actively engaged in grammar analysis through audiobooks and demonstrated a positive attitude towards EL, acknowledging its role in enhancing their vocabulary, pronunciation, and grammar knowledge.

The Covid-19 outbreak has had a negative impact on the decline in the number of visits in the tourism sector, one of which is the tourist village. The recovery of tourist villages during Covid-19 relies heavily on the role of the Tourism Awareness Community (Pokdarwis). However, the role of the Tourism Awareness Community in the development of tourist villages during Covid-19 is still not clearly discussed. Therefore, this study aims to analyze the tourism village development strategy during COVID-19 by the Tourism Awareness Community in the Teritip Village, Balikpapan-Indonesia. This study uses the QSPM (Quantitative Strategic Planning Matrix) method, which is a method for determining the priority of alternative strategies obtained from a SWOT analysis (Strengths, Weaknesses, Opportunities and Threats). The results showed that the position of the Tourism Awareness Community was in quadrant V (Hold and Maintain), namely market penetration and product development strategies. That is, the professional management of tourist villages is crucial to increasing the number of tourist visits. The management of the tourist village must be able to optimize the resources they have to develop a tourist village in the Teritip Village. In addition, the development of attractive tour packages is also the key to attracting tourists. Therefore, strengthening human resources related to the professionalism of tourism village management is very necessary in order to advance tourism villages.

Background: Some studies have shown that Return on Total Assets is a strategy to increase market share. Other studies have also shown that social media like WeChat can increase market share. However, no studies have considered Instagram engagement in increasing market share. Objective: This study aims to identify variable linkage that increases market share through a dynamic system approach in small and medium-sized enterprises (SMEs). Methods: Using a System Dynamics approach, this study presents a model simulation with a proposed increase in market share by considering Instagram features. This approach creates a Causal Loop Diagram converted into a simulated Stock Flow Diagram. The value generated from the simulation is validated with the mean comparison and % error variance formulas. Results: Instagram engagement increases market share from 0.009 to 0.018. Such engagement can be increased by posting regularly and doing more activities, such as increasing post frequency, holding contests, and maximizing all features. Conclusion: This study has successfully modeled information technology, i.e., a promotion module on social media. However, this work has not yet demonstrated how the features can gain more market share, so future research is needed.

A tambourine is one of the musical instruments commonly used in Islam. It is also used in an extracurricular activity in various schools so that many students are familiar with the instrument, making it relevant for learning mathematics. Furthermore, there is an approach to learning mathematics called Indonesian Realistic Mathematics Education (IRME), where students start the learning with contexts close to their lives. This study aims to design a learning trajectory using the IRME approach with a tambourine context to support students' understanding of circles. This learning progresses from the informal stage to the formal through the IRME approach. The study applied design research with three stages: preliminary design, design experiments, and retrospective analysis. The research subjects were 19 six-grade students in one of the elementary schools in Balangan, South Kalimantan, Indonesia. The instruments used were videos to observe the learning process and how students work on the questions given, photos to reference students’ work, and a test in a student worksheet to obtain data on students’ work. The results reveal the learning trajectory practised using the tambourine as the context seen in the student's daily activities. The learning trajectory consists of four events: assembling the tambourine, drawing an illustration of the tambourine, listing the parts of a circle, and solving a problem related to the parts of the circle. In addition, this study also shows that learning trajectory activities have essential roles in supporting students' understanding of the concept of a circle.

Triclustering is a data mining method for grouping data based on similar characteristics. The main purpose of a triclustering analysis is to obtain an optimal tricluster, which has a minimum mean square residue (MSR) and a maximum tricluster volume. The triclustering method has been developed using many approaches, such as an optimization method. In this study, hybrid δ-Trimax particle swarm optimization was proposed for use in a triclustering analysis. In general, hybrid δ-Trimax PSO consist of two phases: initialization of the population using a node deletion algorithm in the δ-Trimax method and optimization of the tricluster using the binary PSO method. This method, when implemented on three-dimensional gene expression data, proved useful as a Motexafin gadolinium (MGd) treatment for plateau phase lung cancer cells. For its implementation, a tricluster that potentially consisted of a group of genes with high specific response to MGd was obtained. This type of tricluster can then serve as a guideline for further research related to the development of MGd drugs as anti-cancer therapy.

Traffic density in the terminal control area will increase flight safety risks. One effort to reduce the risk is to minimize the controller’s workload when affected by air traffic complexity. This research uses a simulation model to measure air traffic complexity in terminal control areas. The aircraft performance model has been constructed from ADS-B data and represents the aircraft movement in the terminal control area of Soekarno-Hatta International Airport. The simulation model can detect and resolve conflicts to keep separations between aircraft at a specified minimum separation limit. Air traffic complexity measurement uses several indicators, i.e., aircraft density, number of climbing and descending aircraft, aircraft type mixing, conflict control, aircraft speed difference, and controller communication. The weighting factor for each indicator has been obtained from Jakarta Air Traffic Service Center (JATSC) controller perception using an analytic hierarchy process. The simulation results show that the variation of resolution type affects the complexity level significantly. The results of this study can be used as consideration for improving air traffic control procedures and air space structures. ABSTRAK: Kepadatan trafik di kawasan terminal kawalan bakal menyebabkan peningkatan risiko keselamatan penerbangan. Salah satu cara bagi mengurangkan risiko adalah dengan meminimumkan beban kerja pengawal yang terlibat dengan kesesakan trafik udara. Kajian ini menggunakan model simulasi bagi mengukur kesesakan trafik udara di kawasan terminal kawalan. Model pretasi pesawat telah dibina menggunakan data ADS-B dan ini mewakili pergerakan pesawat di terminal kawalan lapangan terbang antarabangsa Soekarno-Hatta. Model simulasi ini dapat mengesan konflik dan membuat resolusi bagi mengekalkan penjarakan antara pesawat mengikut had penjarakan minimum yang ditetapkan. Beberapa indikator telah digunakan bagi mengukur kerumitan trafik udara, iaitu: ketumpatan pesawat, bilangan pesawat mendaki dan menurun, jenis pesawat, kawalan konflik, perbezaan kelajuan pesawat dan pengawal komunikasi. Faktor pemberat bagi setiap indikator telah diperoleh daripada pengawal persepsi Pusat Servis Trafik Udara Jakarta (JATSC) menggunakan proses analisis hierarki. Keputusan simulasi menunjukkan pelbagai jenis resolusi mempengaruhi tahap kerumitan dengan ketara. Hasil kajian ini boleh digunakan bagi menambah baik prosedur kawalan trafik udara dan struktur ruang udara.

In implementing Ethnomathematics-Realistic Mathematics Education (Ethno-RME), teaching mathematics correctly is needed through learning practices in teaching and learning activities. This pedagogical activity requires guidance in the form of a curriculum. So, the teacher can determine the ethnomathematics context as a starting point in teaching mathematics using Ethno-RME. Therefore, this paper focuses on constructing an Ethno-RME curriculum to guide teachers to apply Ethno-RME in their learning process. This research was collected data from a few relevant kinds of literature to build the Ethno-RME curriculum, such as literature about the D’Ambrosio trivium curriculum, the principles, and character of RME, and literature about the implementation of RME and Ethnomathematics in school. Then, the data were reviewed, criticized, and synthesized, which was done by integrating the ideas in the literature with the new ideas to form the new concept and formula for Ethno-RME curriculum. This study comprehensively explains the goal of Ethno-RME learning, Ethno-RME competencies, and the procedure of Ethno-RME learning. Its process consists of several steps: determining, exploring, processing, and finding mathematics in the ethnomathematics context. Furthermore, this procedure continues with conducting self-development models and critical reflection as an assessment.

Geometry is one of the essential mathematics materials, such as square and rectangle. However, most elementary school students experience difficulty in understanding it due to the abstractness of the geometric material. Furthermore, teachers teaching in the remote areas of Indonesia still encounter problems exploring this abstract material to make students understand caused by the limited learning resources. On the other hand, students in remote areas are familiar with traditional games, such as Macanan. Hence, the objective of this study is to design learning activities utilizing Macanan game in assisting students understand the concept of the perimeter and area of squares and rectangles for fourth-grade students. A design research approach was implemented and performed at one of the elementary schools in Jambi, Indonesia. The research results presented that Macanan could be a context for a starting point in this learning design of both square and rectangular learning. Employing this context, it would be fun, enjoyable, and easy to understand the perimeter and area of squares and rectangles for students. This game could be a context for teachers in remote areas in teaching geometry and be a reference for identifying other contexts which can make mathematics learning easy in remote areas.

Beach tourism and seaside settlements are perennially popular. Nature's potential as well as the coast's characteristic hybrid art may always entice visitors. The settlements at the foot of the mountain, on the other hand, have their own unique environmental, gastronomic, and cultural identities. Bedugul village (Indonesia), Albarracin village (Spain), Reine village (Norway), Wengen village (Switzerland), Panglipuran village (Indonesia), Hallstatt village (Austria), Patiangan village (Indonesia), and Ora village (Indonesia) are some of the names given to the villages in Indonesia (Greece). They're all mountain communities that have successfully marketed themselves as tourist destinations at the foot of the mountain. The goal of this research is to come up with a viable approach for village branding at the foot of the mountain. This study is a hybrid of action research and development research, with a focus on tourism village acceleration. The Benjor village residents, Benjor village administrators, and a sample of potential visitors were polled for information. The community around Benjor village, the Malang Regency community, and persons outside the Malang Regency were all surveyed for potential visitors. Individual interviews or focus groups, environmental observations, and archives of village office records and Malang Regency government documents were used to gather data. The purpose of this study is to understand the tourism village process before and after therapy. Mining potential excavation yields eleven environmental assets in the form of waterfalls, five culinary assets in the form of chilli sauce, grilled rice, and other similar dishes, and three cultural assets in the form of hadrah, jaranan, and dancing. The development research yielded seven goods that Benjor villagers found to be the most effective in terms of branding. For mountain slope communities, the greatest method is to combine branded items that showcase their artistic, natural, and gastronomic potential.

The introduction of coronavirus disease (COVID-19) into the human population represents a tremendous medical and economical crisis. The immune system plays a central role in protecting against this novel virus. This activity aimed to empower young generation using participatory learning and action approach to improve their knowledge about medicinal plants that grow in Indonesia and whose anti-inflammatory, antioxidant, immunomodulatory, and antiviral properties. Organoleptic test results showed that Kunyit Asam (consisted of turmeric and ginger) and Tealang (consisted of butterfly pea and lemongrass) were highly favored by panelists. Our results provide valuable information on the medicinal plants used as an immunity booster within the studied community.

Background: Commuting time is highly influenced by traffic congestion. System dynamics simulation can help identify the cause of traffic problems to improve travel time efficiency. Objective: This study aims to reduce traffic congestion and minimise commuting time efficiency using system dynamics simulation and scenarios. The developed scenarios implement the Bus Rapid Transit (BRT) and trams projects in the model. Methods: System dynamics simulation is used to analyse the transport system in Surabaya and the impact of BRT and trams project implementation in the model in order to improve commuting time and to reduce congestion. Results: From the simulation results, with the implementation of BRT and tram projects along with highway expansion, traffic congestion is predicted to decline by 24-44%. With the reduction of traffic congestion, travel time efficiency is predicted to improve by 11-28%. On the contrary, implementation of BRT and tram project without highway expansion is predicted to increase the traffic congestion by 5% in the initial year of implementation, then traffic congestion is predicted to decline by 2% in 2035. Conclusion: Based on the scenarios, transport project implementation such as BRT and trams should be accompanied with improvement of infrastructure. Further research is needed to develop a more comprehensive transportation system to capture a broader view of the problem. Keywords: Model, Simulation, System Dynamics, Traffic Congestion, Travel Time

The use of split-type air conditioner in Surabaya results in the almost universal typical apartment layouts which feature a recessed balcony upon the building’s exterior façade which then utilized as air-conditioner condenser unit storage. Façade geometry with recessed balcony itself carries its own characteristic of surface air movement which affects the general Indoor Air Quality (IAQ) and heat dissipation of a building. Nevertheless, façade as architectural elements greatly influence building’s energy performance. Inefficiencies in heat dissipation from a condenser unit is detrimental on its performance and precipitate energy wastage. Based on computational fluid dynamics (CFD) analysis incorporated with energy performance evaluation, the effectiveness of façade geometry with recessed balcony is explored in this paper. It was found that recessed balconies are not an ideal place for condenser unit placement on a façade where many factors contributed to promoting heat re-entry from condenser units into the building’s interior.

Abstract Several studies related to implementing mathematics learning in Children with Special Needs have been widely carried out in Indonesia and published in accredited national journals. However, there has been no article survey on research on mathematics learning for children with special needs in Indonesia. Thus, the purpose of this study is to classify all of these studies into several categories related to research on the implementation of mathematics learning in children with special needs in Indonesia. This study uses the Systematic Literature Review (SLR) method, which is used to identify, review, evaluate, and interpret research on implementing mathematics learning for children with special needs in Indonesia. The data used comes from seventeen articles contained in thirteen mathematics education journals that have been accredited by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia in the Sinta 1 and 2 categories. The results of this study grouped all analyzed articles into five categories, such as subject, level of education, topic, student abilities, and research methods used in these studies. It also contributes comprehensive information about research trends in implementing mathematics learning for children with special needs in Indonesia. Later, they can become recommendations and initial ideas in research on implementing mathematics teaching and learning for children with special needs.

The educational revolution has posed an immense challenge to the world of education. It demands the development of a generation that can take on the challenges and changes bred by the ever-rapid revolution. It is thus inevitable that education must enable improvements of individual hard skills and soft skills that are required to keep up with such changes, including mathematical hard skills and soft skills. The problem is that not all mathematics learning approaches, particularly in the case of Indonesia, are capable of such improvements and of answering to such demands, challenges, and changes that are posed by the revolution. This research seeks to build a theoretical framework out of a systematic analysis based on various pieces of literature that are relevant and fitting to the theoretical framework under development. In this study, a theoretical framework on humanist ethno-metaphorical mathematics learning is developed as a theoretical foundation. This theory is designed for creating a humanist mathematics learning approach based on ethnomathematics and metaphorical thinking to develop students’ mathematical hard skills and soft skills and thus enable them to deal with the current and future problems and changes.

One of indicators to determine the quality of a journal can be observed from how many indexing institutions recognized it nationally and globally, such as Sinta, Scopus, and ScimagoJR. Furthermore, the rank of a journal in the indexing institution will add more value to the reputation of a journal. However, few journal editors are willing to share their experiences in managing a journal, from the beginning to getting recognition at the international level. Thus, this article describes the journey of the first journal in the mathematics education field from Indonesia called the Journal on Mathematics Education (JME), which is globally recognized and indexed on Scopus. JME's journey to gain global recognition is narrated in a structured way, starting from the history of journal formation, recognition at the local level, strategies to get authors from various countries, promotional activities to get credit, until finally getting a global position. In addition, this article also describes many contributions from world-class Mathematics Education researchers who have published their research results in JME. Finally, this article also describes the position of JME at national and international levels based on the data of several indexing institutes and JME's future targets.

Dilakukannya penelitian ini sekaligus dapat dijadikan acuan bagi PT Petrokimia Gresik untuk menurunkan biaya distribusi pupuk agar dapat berjalan dengan lebih optimal.

The assignment problem is one of the fundamental problems in the field of combinatorial optimization. The Hungarian algorithm can be developed to solve various assignment problems according to each criterion. The assignment problem that is solved in this paper is a dynamic assignment to find the maximum weight on the resource allocation problems. The dynamic characteristic lies in the weight change that can occur after the optimal solution is obtained. The Hungarian algorithm can be used directly, but the initialization process must be done from the beginning every time a change occurs. The solution becomes ineffective because it takes up a lot of time and memory. This paper proposed a fast dynamic assignment algorithm based on the Hungarian algorithm. The proposed algorithm is able to obtain an optimal solution without performing the initialization process from the beginning. Based on the test results, the proposed algorithm has an average time of 0.146 s and an average memory of 4.62 M. While the Hungarian algorithm has an average time of 2.806 s and an average memory of 4.65 M. The fast dynamic assignment algorithm is influenced linearly by the number of change operations and quadratically by the number of vertices.

This is qualitative research with a sociological approach used to determine the public acceptance of religious tourism to sacred places such as the Tomb of the Islamic Saints in Tasikmalaya, West Java, Indonesia. The results show that the community has made economic use of tourists that perform pilgrimages to fulfil their psychological needs, such as peace, tranquillity, and a sense of security. Furthermore, local governments’ development of religious tourism makes it easier for visitors to access community facilities and services.

Several Programme for International Student Assessment (PISA) research articles published in Indonesia have contributed to PISA research development in Indonesia, with mathematics as one of the PISA domains. However, there is no research to categorize the PISA research article to give future PISA researchers essential information. Therefore, this study aims to organize PISA research in Indonesia in the period 2016-2020. This study uses the Systematic Literature Review (SLR). The SLR method identifies, analyzes, evaluates, and categorizes specific topics related to PISA research in Indonesia. The research data comes from 27 articles published in thirteen accredited journals in the Sinta 1 and Sinta 2 category by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia as an achievement for review journals, which have excellent management and publication quality. The findings indicated that nine categories were identified in this study, including the PISA articles dominance, the development of PISA model math problems, PISA research and subjects, the research methods, the content and context, students' abilities, and the level of the questions. Lastly, this research contribution also is intended to guide future PISA researchers in determining PISA research trends and the following PISA research opportunities in Indonesia.

The study investigates the effect of interactive media, make a match, and lecture method on learning achievement of virus. The research method used was quasi-experimental (quasi-experimental) with the pretest-posttest non-equivalent control group design. This research was conducted from September 2019 to November 2019 in High School A and High School T with a duration of learning ± 3 hours of study.ANOVA test results on the average value of N-Gain showed the same results as the post-test. N-Gain in ICT learning media class, make a match learning model class and lecture learning method classes respectively amounted to 58.6 ± 13.6, 40.8 ± 17.6 and 40.5 ± 14.3. However, based on linear regression analysis, student learning outcomes are influenced by student perception factors and students' visual learning styles (P

Indonesia has many cultures that can be used as a starting point in learning mathematics. Yet, many teachers still use conventional methods to provide explicit mathematical content without connecting with students' culture and daily activities. One of the learning approaches that can solve these problems is Realistic Mathematics Education (RME). This approach uses context as one of its characteristics containing students' culture and their daily activities. On the other hand, Wayang (Indonesian shadow puppets) and Mahabharata stories have the characteristics that can be a context in the learning of set. This research aims to design the Hypothetical Learning Trajectory (HLT) of the set using the RME approach through Wayang and Mahabharata stories, which are familiar with students' culture in Yogyakarta. This HLT will then be tested on students in further research until it becomes the Local Instructional Theory (LIT) on set. Students can study about set by grouping Wayang in Mahabharata stories based on their characters. The research result is the HLT of set through the context of wayang and Mahabharata stories containing learning goals, learning activities, and the conjecture of every activity. This HLT can be a promising solution to overcome students' difficulties in understanding the concept of sets and values in the cultural context to improve the students' character.

Slow Learner students often have difficulty understanding mathematics content, one of which is direct and inverse proportion. This study aims to improve the student's understanding of the direct and inverse proportion material using the Contextual Teaching and Learning (CTL) approach. The research subject in this study was a single subject, namely Slow Learner student who studied in seventh grade in one of the Junior High School in Bantul district, Yogyakarta Special Region. This study used the Single Subject Research method with an A-B design. Researchers collected the data in this study through audio documentation, photos, videos, and written documentation. The data were then analyzed using analysis in conditions and between conditions. The results showed that students had an average score of learning outcomes that was 32 before being given intervention and had an average score of 78 after being given an intervention to implement learning with the CTL approach. This result shows that using the CTL approach can improve the understanding of Slow Learner student in understanding the direct and inverse proportion and minimizing the learning difficulties of Slow Learning student during teaching and learning activities.

This study aimed to evaluate the effect of relaxation music therapy (RMT) to reduce academic anxiety before carrying out the final academic exam. The type of this research is Pre-Experiment with one group pretest-posttest design. The subjects in this study were 51 final year students preparing for their final academic examinations at Universitas Jambi, using purposive sampling. The instrument used was an anxiety scale. Data analysis used nonparametric statistical techniques using the Wilcoxon Signed-Ranks Test and the Rasch Model. The results show that there is an effect of RMT to reduce academic anxiety of final year students at Universitas Jambi. Furthermore, the ability of students to respond to the pretest was still in anxious condition which resulted in the results of the pretest being still moderate (mean measure = 0.04 logit). In contrast, when RMT has been given treatment, the student's ability to respond to the posttest has become low (mean measure = -0.49 logit). These findings could be used by counselors to reduce academic anxiety of final year students at the University and the implications of guidance and counseling are discussed further.

Measuring teachers' skills and competencies is necessary to ensure teacher quality and contribute to education quality. Research has shown teachers competencies and skills influence students’ performances. Previous studies explored teachers’ knowledge through testing. Teachers' knowledge of the topic of area-perimeter and teaching strategies has been assessed through testing. In general, items or tasks to assess mathematics teacher knowledge in the previous studies were dominated by subject matter knowledge problems. Thus, it seems that the assessment has not fully covered the full range of teacher knowledge and competencies. In this study, the researchers investigated mathematics teachers’ Knowledge of Content and Students (KCS) through lesson plans developed by the teachers. To accommodate the gap in the previous studies, this study focuses on KCS on the topic of area-perimeter through their designed lesson plans. Twenty-nine mathematics teachers attended a professional development activity voluntarily participated in this study. Two teachers were selected to be the focus of this case study. Content analysis of the lesson plan and semi-structured interviews were conducted, and then data were analyzed. It revealed that the participating teachers were challenged when making predictions of students' possible responses. They seemed unaware of the ordinary students' strategies used to solve maximizing area from a given perimeter. With limited knowledge of students' possible strategies and mistakes, these teachers were poorly prepared to support student learning.

This study initially carried out mapping geodiversity along the Citarum River area and identified the potential for Citarum geotourism, mapping stakeholders in Citarum geotourism. Of the nine sectors (Upper Citarum Zone) of the Citarum River Area mapped, one village can represent the geotourism area, namely Cibeureum Village, Kertasari District, Bandung Regency. This research's research type is PAR (Participatory Action Research) with primary and secondary data collection. Meanwhile, data analysis uses qualitative and quantitative analysis methods (mixed method), content analysis, map analysis, geodiversity analysis, and is equipped with qualitative and quantitative descriptive analysis methods. The results of this study indicate that community participation has yielded benefits for local communities. However, many things need to be provided to the community from various skills to benefit all parties, including maintaining geodiversity sustainability in the geotourism area.

Learning mathematics has a significant contribution to the students’ daily activities, one of which is on social arithmetic topic. The implementation of social arithmetic, in general, is mostly found in buying-selling and banking activities. However, students still find difficulties in understanding this topic. It is because the teaching and learning activities still use a conventional approach, which restricts the students to imagine how it is implemented in daily life. Therefore, this paper aims to describe the innovative learning activities of social arithmetic among junior high school students using the Realistic Mathematics Education (RME) approach. This research was conducted in three meetings, and the researcher acted as the teacher in the class. The results showed that the innovative learning of social arithmetic using the RME approach and word problems could improve the students’ learning outcomes with an average score of 81.92% and 92.59% of the total of students scored above passing grade.

Mathematics exists as rooted in human ideas, ways, and techniques to respond to their environments. Along with its development, mathematics has been taught through formal education or schooling in the flat- not flexible ways and far from students' social and cultural lives. Indonesia is rich with culture, including the Special Region of Yogyakarta (DIY). It is called a city of culture. Educators are not yet aware of this richness in the learning process to integrate it as the starting point. It is hard to find in mathematics textbooks in Indonesia, which put cultural context as starting points. Therefore, this study aims to explore Yogyakarta's culture in terms of contexts used in mathematics learning. It is an ethnography study. Furthermore, the data was collected through literature artifacts, field observation, and interviews with resource persons who understand the seasons, system, and calculation of birth and death days. It is to clarify the researcher's understanding of the literature. This study showed that Yogyakarta's people use mathematical modeling to determine the seasons' system and funerary dates. These models have the potential to be used as a starting point in learning mathematics.
