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

Full text linkPenelitian yang dilakukan di Pulau Pasaran, Bandar Lampung, membahas tantangan yang terkait dengan pengelolaan sampah di wilayah tersebut. Kompleksitas pengelolaan sampah ini timbul karena adanya ketergantungan pada berbagai sektor yang berbeda. Studi ini bertujuan untuk melakukan analisis yang terintegrasi, dengan fokus pada aspek timbulan sampah, komposisi sampah, dan pemangku kepentingan yang terlibat. Metode AHP digunakan untuk menilai 21 sub-kriteria yang telah diidentifikasi dalam lima kriteria pengelolaan sampah. Pengumpulan data dilakukan melalui pengambilan sampel yang mengikuti standar SNI-19-3694-1994, wawancara, penggunaan kuesioner, serta metode dokumentasi. Analisis pemangku kepentingan dilakukan terhadap sepuluh responden, dan hasilnya mengungkapkan bahwa aspek lingkungan memiliki tingkat kepentingan yang lebih tinggi dalam pengambilan keputusan terkait aspek pengelolaan, dengan bobot sebesar 0,326. Sub-kriteria yang diidentifikasi sebagai prioritas yang perlu dipertimbangkan dalam proses pengambilan keputusan ini meliputi kemudahan pemeliharaan, partisipasi masyarakat, polusi tanah dan air, kerjasama antar pemangku kepentingan, serta peningkatan manfaat bagi masyarakat. Dari berbagai alternatif yang dipertimbangkan, model pengelolaan skala rumah tangga yang melibatkan pemilahan dan pengomposan, serta didukung oleh konsep bank sampah dan pemanfaatan oleh RINDU, muncul sebagai pilihan yang paling sesuai.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
Land Capability Analysis for Sustainable Land Use Planning: A Case Study of Bogor Regency, Indonesia
Full text linkUncontrolled land use changes can lead to mismatches with designated spatial patterns, resulting in critical land issues such as erosion and flooding. Bogor Regency has undergone rapid land use transformations, particularly in agriculture, with significant shifts occurring between 1995 and 2001. This study evaluates land capability using a matching and scoring approach to determine its suitability concerning existing spatial patterns. Key factors such as slope, erosion hazards, and soil depth were analyzed to classify land into capability categories. The findings reveal six classes of land capability, ranging from Class II to VII, with Classes IV and VI being the most dominant. Spatial analysis indicates that a large portion of Bogor Regency\u27s land cover aligns well with its land capability. Compatibility with designated spatial patterns is predominantly conditional, suggesting that some areas may require mitigation measures or adjustments for sustainable development. The conditional suitability of land capability with spatial patterns highlights the need for careful planning interventions. Decision-makers must consider land constraints and adopt adaptive land-use policies to mitigate risks such as erosion and flooding. Integrating land capability assessments into planning frameworks can enhance sustainable land management and minimize environmental degradation

This marine protected area (MPA) covers a total area of 1,385.61 km2. In 2014, due to the implementation of a new government law, the management authority of this MPA changed, resulting in its institutional redesign. The process was completed in April 2022. As a new MPA, the management activities have not been carried out optimally because the management resources were still limited. Thus, this research aims to evaluate the management effectiveness of Bintan MPA. The research was conducted in the Bintan MPA and took place from October 2021 to October 2022. Informants involved in this research were selected using purposeful sampling and snowball sampling method. The data collection methods were interviews (structured and in-depth) and document verification. EVIKA assessment was used for data analysis. There were four criteria assessed: input, process, output, and outcome, each with several indicators. The percentage results of each criterion were 79.53%, 34.88%, 21.54%, and 27.20%, respectively. The final percentage of the EVIKA assessment was 41.56%, with an effectiveness status of "minimally managed" and a "bronze" label. This means that the conservation area design and management process had been carried out, but efforts were still needed to achieve the management goals. 
Spatial Distribution of Local Sustainability Index in the Ciletuh-Palabuhanratu UNESCO Global Geopark Using Spatial Autocorrelation
Full text linkThe 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.

Seasonal Assessment of Water Quality and Pollution Index of Cileungsi River in Bogor Regency, Indonesia
Full text linkThe Cileungsi River is the upstream part of the Bekasi Watershed, and its existence is crucial for the sustainability of the local economy and the survival of the community, industry, agriculture, and commerce surrounding the riverbanks. It is also the raw water source for Regional Water Company. This study aims to assess the water quality of the Cileungsi River and its pollution status using the Pollution Index (PI) method. This research was conducted at six sampling points, covering the upstream, middle, and downstream sections in both the dry and rainy seasons of 2022. The method used to analyze the water quality of the Cileungsi River refers to the Indonesian National Standard. In contrast, the calculation of the PI refers to the Decree of the State Minister of Environment. During the dry season, the PI at the Regional Water Company bridge in Kota Wisata and beside PT Rahayu Indah Kulit fell into the moderately polluted category, with PI values of 5.49 and 7.30, respectively. The highest PI value during the rainy season was recorded at 10.30 on the border of Bogor Regency and Bekasi City, which falls within the heavily polluted category. The Gunung Putri area has a lightly polluted index value in both seasons. The parameters that require attention are BOD, NO2-, free chlorine, and fecal coliform, which serve as indicators of pollution from household and agricultural activities. These results will help the Bogor Regency government develop strategies to protect and sustainably manage the Cileungsi River.
