In the long term, this phenomenon will threaten efforts to fulfill the adequacy of rice and increase the potential for a food crisis. This study analyzes the decline in domestic rice sufficiency due to destroying rice fields in the Banyumas Regency. This study was conducted using spatial modeling and the Micmac method. Respondents and experts were purposively determined based on the roles of 50 respondents and seven experts. The findings revealed that, on average, 103 hectares of rice fields in the Banyumas Regency were lost annually between 2007 and 2019. In 2045, it is estimated that the area of rice fields in Banyumas Regency will be 29,160 hectares, with a conversion rate from 2019 to 2045 of 1,384 hectares. Several driving factors are distance from the district capital, distance from roads, distance from settlements, distance from the irrigation channel, and population density. The essential factors influencing rice self-sufficiency include enforcing rice field preservation regulations, incentivizing measures for protecting rice fields, comprehensive spatial data on rice fields, sufficient access to irrigation water, proactive engagement of farmer collectives, and level of rice productivity

Traditional Agroforestry Models Based on Local Knowledge in the Mount Mutis-Timau Highlands,Timor Island, Indonesia

The adoption of local knowledge in land management is a fundamental aspect that determines the success of managing agroforestry systems to support food security and improve community welfare. This study aims to examine the application of local community knowledge in managing owned land using an agroforestry model. Data were collected through a series of systematic stages, including indepth interviews with respondents who were heads of households and community leaders, direct observation of the land, and literature studies related to agroforestry patterns. A descriptive analysis using a qualitative approach was conducted to obtain important information regarding the actual conditions observed. The results show that the construction of local knowledge is determined using space by intervening with various plants on a plot of land. The crop planting intervention consisted of three models: intercropping, annual/plantation plants as a fence dividing the land, and forestry plants separated from agricultural/plantation plants. Farmers in Ajaobaki and Fatumnasi Villages choose seasonal crops (corn and beans) to meet food needs, plantation crops (Aleurites moluccana (L.) Willd, Citrus reticulata, Persea americana, Artocarpus heterophyllus, and Mangifera indica) to increase income and ecological functions, and forestry crops (Casuarina junghuhniana,Eucalyptus urophylla, Tectona grandis L.f, and Gmelina arborea), which provide both economic and ecological benefits. Planting a combination of plant types on land can indirectly anticipate climate change and, on the other hand, can improve community welfare and protect the environment in the area

Bioassay the Composition of the Organic Pot as a Container Media for Balsa (Ocrhoma bicolor Rowlee) Growth in Nursery

Forestry plant seedling production uses non-eco-friendly polybags. Organic pots are a solution that can be applied. This research aimed to analyze the composition and size of raw materials in organic pots for balsa growth and to examine the composition of raw materials in organic pots appropriate for balsa growth. This study used a factorial complete randomized design (CRD). There are two factors: the organic pot composition factor (A) and the mesh size factor (M). The observed parameters included the C/N ratio of organic pots, height, diameter, biomass, and plant chlorophyll content. The results showed that the highest percentage decrease in the C/N ratio was found in the A3M2 treatment. The highest average value of balsa plant growth was found in the A3M2 treatment (15% newspaper, 80% goat manure, 5% cocopeat, and ten mesh material size). The highest chlorophyll content was found in A3M1 treatments (15% newspaper, 80% goat manure, 5%cocopeat, five mesh material size). Organic pots with low C/N ratio values had higher average increases in height and diameter of plants compared to organic pots with high C/N ratio values. The optimal composition of the organic pot in this study was the A3M2 treatment.&nbsp

Spatial Distribution of Local Sustainability Index in the Ciletuh-Palabuhanratu UNESCO Global Geopark Using Spatial Autocorrelation

The Ciletuh-Palabuhanratu UNESCO Global Geopark (CPUGG) is a geopark area that is also a tourist destination in Sukabumi, West Java, Indonesia. CPUGG is experiencing rapid regional development, which can be seen from the increase in tourist visitors, changes in land use from agricultural land to built-up areas, the rapid growth of infrastructure and facilities, and the emergence of various economic activities. This study aims to determine local sustainability performance based on the spatial distribution pattern of the local sustainability index (LSI) in CPUGG using a spatial autocorrelation approach. The results show that the CPUGG development is not evenly distributed yet. The spatial distribution pattern of the local sustainability index in economic, social, and environmental are clustered. Each clustering shows that each village influences the surrounding villages. So, increasing the economic, social, and environmental sustainability index in several villages with a low sustainability index is necessary. Good cooperation is needed between the government, society, and several stakeholders to improve economic, social, and environmental development in The Ciletuh-Palabuhanratu UNESCO Global Geopark, West Java, Indonesia.&nbsp

Power Struggles and Conflict Visibility in Contested Political Forests: A Case Study in Sukaslamet Village, Indramayu Regency, Indonesia

Forest tenure conflicts have been a problem in Perhutani's management areas for decades. As an entity authorized to manage, exploit, and protect most of the forest areas in Java, Perhutani's forest management is not free from land occupation issues. The duality in viewing land rights between Perhutani from the legal side and the community from the historical side of control is a narrative that continues to be debated and is challenging to resolve. This study aims to describe the local dynamics of forest tenure conflicts through empirical evidence of the historical trajectory of forest tenure in the Perhutani management area in Indramayu. Using a qualitative research method, this study presents case studies of land tenure conflict events within the framework of conflict visibility assessment and the Actor-Centered Power (ACP) approach in its analysis. The results of the conflict visibility assessment show the gradation and historiography of forest tenure conflicts in Perhutanimanaged areas and produce several important findings to complement the forest tenure conflict literature. The research findings show how shifts in actor power led to changes in forest tenure conflicts in Indramayu. Finally, the establishment of the Forest Areas with Special Management policy as an effort to resolve conflicts can cause new contestations by inviting other powerful actors. Konflik tenurial hutan telah menjadi masalah di wilayah kelola Perhutani selama puluhan tahun. Dualitas dalam memandang hak atas tanah antara Perhutani dari sisi hukum dan masyarakat dari sisi historis penguasaan menjadi narasi yang terus diperdebatkan dan sulit untuk diselesaikan. Penelitian ini bertujuan untuk menggambarkan dinamika lokal konflik penguasaan hutan melalui bukti-bukti empiris lintasan sejarah penguasaan hutan di wilayah kelola Perhutani di Indramayu. Studi ini menyajikan studi kasus peristiwa konflik tenurial dalam kerangka penilaian visibilitas konflik dan pendekatan Actor-Centerd Power (ACP) dalam analisisnya. Hasil penilaian visibilitas konflik menunjukkan gradasi dan historiografi konflik tenurial hutan di wilayah kelola Perhutani dan menghasilkan beberapa temuan penting untuk melengkapi literatur konflik tenurial hutan. Temuan penelitian menunjukkan bagaimana pergeseran kekuatan aktor menyebabkan perubahan konflik tenurial hutan di Indramayu. Terakhir, penetapan kebijakan KHDPK sebagai upaya penyelesaian konflik dapat menimbulkan kontestasi baru dengan mengundang aktor-aktor kuat lainnya

The Effect of Information, Fear, and Risk Perceptions to Pro-Environmental Behavior among University Students in Indonesia

Climate change is a serious threat to human safety and health. Pro-environmental behavior can avoid more serious risks and harm. Pro-environmental behavior is influenced by information, fear, and risk perceptions. As future educators, planners, and policymakers, it is critical to understand the factors influencing students' pro-environmental behavior. This study, therefore, aims to examine the factors influencing students' pro-environmental behavior based on the Protection Motivation Theory. A 77-item questionnaire was completed by 415 students from the Faculty of Arts and Languages, Science, and Education, randomly selected using the cluster sampling method in their last lecture class. Confirmatory factor analysis and structural equation modeling showed that information, fear, and risk perception (reward, perceived severity, and perceived vulnerability) are both directly and indirectly mediated by motivation. In addition, the research identified the indirect and negligible effects of various protection motivation theory factors, including cost, responseefficacy, and self-efficiency. Further, an unexpected finding determines that pro-environmental behavior was unrelated to demographic and socioeconomic background. Overall, the study's outcomes offer recommendations to socialize the risks climate change better causes to human health and safety, increasing fear and risk perceptions that may improve pro-environmental behavior. Additionally, stricter environmental behavior regulations are needed to penalize polluters and stop rewarding maladaptive behaviors

Potential for Developing Access to Safe Drinking Water in the Highlands Area (Case Study: Bogor City, Indonesia)

The need for water in Indonesia is not directly proportional to its availability. This challenge is not limited to rural areas but also affects urban areas like Bogor City. Since 2004, Regional drinking water company of Bogor City has been classified as healthy and is a pilot city for the prime drinking water zone program alongside two other Indonesian cities. This research aims to assess Bogor City's potential for safe drinking water development, considering the physical environment, readiness of the drinking water system, social conditions, and economic conditions of the community. The methodology used is mixed with a quantitative approach via spatial analysis. The physical environment variable yielded 4 classifications: high potential, potential, moderate potential, and low potential. The very potential classification was dominant in 45 sub-districts. The drinking water system readiness had 4 classifications: potential, moderate potential, low potential, and no potential, with the moderate potential dominating in 51 sub-districts. The community social condition had 4 classifications: potential, moderate potential, low potential, and no potential, with the low potential dominating in 36 sub-districts. The community economic condition variable resulted in 4 classifications. Moderate potential dominates in 29 sub-districts. Bogor City has moderate potential for developing access to safe drinking water. The key factors for this classification are the community's social and economic conditions, as well as the drinking water system's readiness

A Model of Sustainable Waste Management Based on Climate Village Program in Pasaran Island, Lampung Province, Indonesia

Research focuses on waste management challenges on Pasaran Island, Bandar Lampung, examining waste generation, composition, and stakeholder involvement. Data was collected through solid waste sampling, interviews, questionnaires, and documentation, following the SNI-19-3694-1994 standard. A sample size of 20 households was determined using the Slovin formula, and 10 stakeholders from various sectors were selected for analysis. The study used the Analytic Hierarchy Process (AHP) to identify an effective waste management model aligned with the Climate Village Program. The analysis highlighted key factors such as maintenance ease, community participation, and pollution control. Among the alternatives, a household-scale model involving sorting, composting, waste banks, and the House of Recycling Innovation (RINDU) emerged as the most suitable. The findings suggest that enhancing waste management facilities like waste banks and RINDU would support the Ministry of Environment and Forestry’s programs and align with local regulations. This study offers insights that could benefit other small islands or communities facing similar waste management challenges.Penelitian yang dilakukan di Pulau Pasaran, Bandar Lampung, membahas tantangan yang terkait dengan pengelolaan sampah di wilayah tersebut.
