Ketersediaan dan akses yang merata terhadap energi bersih merupakan suatu tantangan yang dihadapi saat ini. Indonesia sebagai negara produsen minyak sawit mentah Crude Palm Oil (CPO) di dunia dengan produksi mencapai 45.12 juta ton pada tahun 2021. Seiring dengan peningkatan volume produksi yang besar tersebut akan menghasilkan sejumlah besar limbah cair pabrik sawit atau Palm Oil Mill Effluent (POME). Penguraian POME secara anaerobik akan menghasilkan biogas yang dapat digunakan sebagai sumber energi terbarukan. POME yang tidak dikelola dengan baik akan berdampak negatif terhadap lingkungan dikarenakan kandungan Chemical Oxygen Demand (COD) yang tinggi, apabila langsung dibuang ke kolam terbuka maka akan melepas gas metana ke atmosfer sebagai emisi gas rumah kaca (GRK). Namun jika dikelola dengan tepat akan memberikan nilai tambah secara ekonomi, sosial dan lingkungan terutama dalam hal pengurangan GRK dan pencemaran sumber daya air. Di provinsi Jambi terdapat sekitar 80 Pabrik Kelapa Sawit (PKS), namun hanya sedikit yang belum memanfaatkan POME sebagai sumber energi terbarukan. Tujuan dari studi ini adalah untuk membahas potensi energi terbarukan dari pemanfaatan energi biogas POME. Penelitian ini menggunakan metode deskriptif dengan melakukan survey. Hasil penelitian menunjukkan karakteristik POME memiliki suhu 70 -90 0 C, bersifat asam dengan pH 4 -5,5 dan kandungan COD tinggi yaitu 80.000 -120.000 mg/L, dengan proses anaerobik sistem tangki reaktor menghasilkan biogas dengan rasio sekitar 30 -40 Nm 3 /ton POME. Biometana sebagai komponen utama biogas yang dihasilkan dari penguraian POME dapat digunakan sebagai sumber energi terbarukan pengganti fosil. Potensi energi terbarukan dari POME di Provinsi Jambi cukup besar dengan total kapasitas pabrik pakai sebesar 3.026 ton TBS/jam, berpotensi menghasilkan energi listrik sebesar 969 GWH/tahun.

Sayangnya, konsumsi plastik yang tinggi tidak diikuti dengan pengelolaan yang tepat sehingga menyebabkan sampah plastik yang berasal dari darat masuk ke badan sungai kemudian berakhir di wilayah pesisir dan mencemari lingkungan. Penelitian ini dilakukan di Desa Pengarengan, Kabupaten Cirebon, Jawa Barat. Sungai Pengarengan merupakan jalur transportasi kapal nelayan menuju Laut Jawa sehingga aktivitas masyarakatnya yang tinggi berpotensi menimbulkan pencemaran sampah ke lingkungan sekitarnya. Tujuan penelitian ini adalah menganalisis karakteristik sampah plastik serta mengevaluasi hubungan antara aspek pengetahuan dan sikap dengan perilaku masyarakat terkait sampah plastik yang mencemari lingkungan. Metode yang digunakan adalah kelimpahan pelepasan sampah dan puing-puing sampah dikumpulkan di dua titik sampling dengan menggunakan jaring yang memiliki ukuran mata jaring 5cm, dipasang pada waktu pagi hari sesuai lebar sungai. Data perilaku masyarakat terhadap sampah plastik diperoleh dari 110 responden dengan menggunakan teknik accidental sampling. Hasil penelitian menunjukkan total kelimpahan puing sampah sungai adalah 13.200 ± 1.678 item dan 14.976 ± 1.772 item. Kelimpahan puing sampah sungai tertinggi adalah bungkus sampah plastik tipis sebanyak 47% dan 46%, diikuti kayu ranting (39% dan 33%), styrofoam (3,6% dan 5,5%), sedotan (1,8% dan 2,2%), gelas plastik (1,5% dan 2,6%), kotak makanan, peralatan plastik, dll (1,4% dan 1,6%), serta plastik lainnya (2,2% dan 2,3%). Analisis statistik Kruskal Wallis menunjukkan tidak terdapat perbedaan rata-rata yang siginifikan pada kelimpahan total puing sampah sungai di kedua titik sampling p= 0,875 (p> 0,05). Hasil evaluasi perilaku masyarakat menunjukkan bahwa aspek pengetahuan memiliki kategori penilaian sangat baik (4,08), aspek sikap dengan kategori kurang baik (2,89), dan aspek perilaku dengan kategori baik (3,88). Analisis korelasi Pearson menunjukan terdapat hubungan positif yang kuat (r= 0,664) dan signifikan (0,000) antara aspek pengetahuan dengan perilaku, kemudian aspek sikap dengan perilaku mempunyai hubungan positif yang sangat lemah (r=0,183) dan signifikan (0,028).

The implementation of the food estate program in Indonesia needs to comprehensively consider environmental, economic and social aspects, so that it will not only provide benefits to the wider community, but also pay attention to the ecological functions of the peatland ecosystem. In this paper, a study is carried out on several aspects such as the availability and potential of peatlands for agriculture, the right commodities for agricultural activities on peatlands, examples of the economic benefits of peatland agriculture, and the involvement of local communities as indicators of sustainability of the food estate program. The discussion is carried out using the perspective of environmental science and FEW Nexus. The results of this study explain that the food estate program on peatlands needs to pay attention to several challenges in the environmental, social, and economic sectors. Furthermore, food estate on peatlands is also considered necessary to be implemented within the framework of the FEW Nexus in order to become a sustainable program.

Agroforestry seeks to achieve multifunctional, efficient, and environmentally sustainable production by replicating forest-like circumstances and employing management strategies that align with the cultural values of local people. The successful execution of this strategy is facilitated by the improvement of soil and microclimate conditions, which positively impact agricultural results. The Lore Lindu National Park (TNLL) is an officially declared national park in the Central Sulawesi province of Indonesia. The location plays a crucial role in conserving Sulawesi Island's rich array of biological diversity. The research findings indicate that the flora variety within the TNLL region encompasses a wide range of botanical species, including diverse trees, resin-producing plants, rattan, orchids, and medicinal plants. The agroforestry patterns seen in the buffer region of the TNLL can be categorized as the agrisilviculture model. This model represents an agroforestry system that integrates plant and agricultural components, specifically nonwood species. The pattern under consideration encompasses several components, including tree plants such as cocoa, durian, cloves, and candlenuts, alongside agricultural components like corn, vegetables, and tubers. The historical trajectory of land utilization commenced with the indigenous communities who exercised stewardship over the vicinity surrounding TNLL, employing their indigenous knowledge and practices as a consequence of their successful adaptation to the prevailing natural circumstances. The utilization of natural resources by indigenous groups within national park regions for their daily necessities is frequently perceived as exerting strain on the protected landscape's ecological integrity and long-term viability.

Plastic may be considered profitable for the company for their products because it is easy to use and has a low price which economically benefical for the company. However, problems may arise due to its nature of being hard to break, the material making it difficult to decompose, causing piles of plastic waste. Therefore, this research aims to determine the level of environmental awareness in individuals. We aim from the humanperspective since human are the subject of plastic users in daily life, as we access the level of knowledge, attitude, and behavior towards plastic use. We used a quantitative research method and distributed questionnaires to 268 respondents. Distributed frequency analysis was done using SPSS, and we categorized the total scores of each variable into two groups. Then, we composite the three variables to determine the level of environmental awareness. Results show that based on respondent's knowledge, attitude, and behavior towards plastic use, the majority of respondents, about 55.6% have good environmental awareness, whereas the other 44.4% have poor environmental awareness. This result indicates that the respondents already have formed their awareness, which may be beneficial in forming their pro-environmental behavior in future daily life, therefor aiming for future sustainable behavior of plastic use, especially plastic for packaging.

In past time, the space authorization was related with advancing technology by many space mission and various satellite launchings, or it could be said that who ruled technology will rule the space. Therefore, the numerous satellites in the space could be a threat for the countries which are mainly located in the path of the satellite, especially in the equatorial region including Indonesia. This study aims to create a policy scenario in mitigating the threat of space debris. The results showed that although space debris was not threatened national security for now, but the potential and its impact on the future potentially harmful. The threats of orbit circulation for some experts considered as a threat for national security, because its danger potential which caused by space debris could significantly damage the affected areas. However, until now Indonesia has no comprehensive mitigation strategy for space matters although it has been ratified by the United Nations Convention.

This problem is illustrated by high plastic consumption and poor plastic waste management. The purpose of this paper is to discuss community environmental awareness regarding the use of plastic packaging. This paper uses a qualitative approach with an analysis of the literature study. From the results of the study, it was found that community environmental awareness is still low. It is necessary to increase awareness to encourage environmentally friendly plastic usage behavior. Behavior toward the use of plastic starts from minimizing its consumption and the willingness to sort and recycle. Many factors influence the willingness to participate in plastic management. By manipulating these factors, a sustainable plastics management strategy can be achieved. Raising awareness through increasing knowledge, increasing guilt, optimizing facilities, and supporting regulations. Strategy cannot work without the cooperation of various stakeholders. The common goal of creating a healthy and clean environment and an empowered community is the impetus for improving plastic management.

This study aims to assess waste handling in palm oil plantation manage by smallholders and the correlation palm oil plantation waste handling with the fireland in Sumatera, especially on Jambi province. METHODS: Primary data collection was conducted in September 2019, and a purposive random sampling method was used to select respondents. Primary data collection was applied for four hundred smallholders in five districts in Jambi using a mixed method. FINDINGS: Out of 400 correspondents that handle their waste, 50% of respondents handle the residues by stacking the waste on their field, 25% of correspondents stack the waste between trees, 17.25% of correspondents stack the waste on piles, 5% of them bury the posts, and 2.75% incinerate the waste. The average distance from home to the field for 200 correspondents is 8.825 kilometres, and they have the highest harvest quantity with a mean of 1.0940 tons. Most of them are common smallholders and self-subsistent smallholders. The 298 correspondents join a farming association. About 50% of smallholders in Jambi handle the residues by stacking the wastes on their field instead of incinerating the waste. CONCLUSION: Out of the overall samples collected in this study, only 2.75% smallholders in Jambi incinerate their residues. Hence, the fire breakouts happened on several provinces in Sumatera and Kalimantan in late 2019 did not happen due to crude palm oil waste-handling activities.

This study aims to assess the status and utilization of R. apiculata, primarily by the fishermen community living near Muara Angke Wildlife Reserve in Jakarta Bay, Indonesia. The density of R. apiculata was determined by placing 100-meter-long transects from west to East in Muara Angke. While the normalized difference vegetation index (NDVI) of R. apiculata was studied using Landsat 8 satellite images with specific near-infrared and red wavelengths. The utilization of R. apiculata was assessed through interviews with 108 fishermen. The results showed that the west parts of Muara Angke had higher density, NDVI values, and canopy covers, with the R. apiculata density, NDVI, and canopy cover ranges being 3339.5-2856.3 Ha-1 trees, 0.79-0.99 percent, and 90-100 percent. There was a positive relationship between R. apiculata density, NDVI, and cover and the distance to the fishermen's village, decreasing NDVI trends toward villages. NDVI values in R. apiculata populations located far (> 1 km) from villages were higher, while NDVI values in R. apiculata populations located close (1 km) to villages were lower. Low density and NDVI values near the village were linked to fishermen's understanding and use of R. apiculata. This research can help to conserve and sustainably use the remaining mangrove community, primarily in Jakarta Bay.

T... more Forest fire in Indonesia is a cataclysmic event that routinely happens consistently every year. The Indonesian government's intervention in suppressing forest fires is often carried out when massive fires have already occurred massively. When it happens in peat soil, forest fires become hard to extinguish because of the characteristics of burning below the ground surface, better known as the phenomenon of peat smoldering. Thus, that condition challenges the mitigation of forest fires in Indonesia to prioritize preventive principles in its implementation, one of which is through observing the physical condition of peatlands. This study examines and identifies existing regulations and policies concerning forest fires disaster mitigation by taking Riau Province as study area, one of Indonesia's areas that are, in many cases, hit by forest fires annually. Through the analysis of literature studies of relevant sources, this paper seeks to provide input on how monitoring the physi...

This problem is illustrated by high plastic consumption and poor plastic waste management. The purpose of this paper is to discuss community environmental awareness regarding the use of plastic packaging. This paper uses a qualitative approach with an analysis of the literature study. From the results of the study, it was found that community environmental awareness is still low. It is necessary to increase awareness to encourage environmentally friendly plastic usage behavior. Behavior toward the use of plastic starts from minimizing its consumption and the willingness to sort and recycle. Many factors influence the willingness to participate in plastic management. By manipulating these factors, a sustainable plastics management strategy can be achieved. Raising awareness through increasing knowledge, increasing guilt, optimizing facilities, and supporting regulations. Strategy cannot work without the cooperation of various stakeholders. The common goal of creating a healthy and clean environment and an empowered community is the impetus for improving plastic management.

This condition causes low awareness of farmers to manage livestock waste because it is considered not to be of economic value. Managing livestock for production and handling waste is more efficient when using a communal enclosure system. Hence the purpose of this study is to analyze community understanding of sustainable communal cattle shed management. This study generally uses a quantitative approach. The research method used is a mixture (mix method) of quantitative and qualitative methods. The research data were analyzed by descriptive statistical analysis procedures and using SPSS 19.0 software. The relationship of community behavior with an understanding of sustainable communal cattle-shed was tested using Kendall's Tau correlation. Based on the results of the analysis of the relationship and the influence and conditions in the field, all variables observed had a significant relationship, had a significant and direct effect on community understanding of communal cattleshed management.

This study aims to assess waste handling in palm oil plantation manage by smallholders and the correlation palm oil plantation waste handling with the fireland in Sumatera, especially on Jambi province. METHODS: Primary data collection was conducted in September 2019, and a purposive random sampling method was used to select respondents. Primary data collection was applied for four hundred smallholders in five districts in Jambi using a mixed method. FINDINGS: Out of 400 correspondents that handle their waste, 50% of respondents handle the residues by stacking the waste on their field, 25% of correspondents stack the waste between trees, 17.25% of correspondents stack the waste on piles, 5% of them bury the posts, and 2.75% incinerate the waste. The average distance from home to the field for 200 correspondents is 8.825 kilometres, and they have the highest harvest quantity with a mean of 1.0940 tons. Most of them are common smallholders and self-subsistent smallholders. The 298 correspondents join a farming association. About 50% of smallholders in Jambi handle the residues by stacking the wastes on their field instead of incinerating the waste. CONCLUSION: Out of the overall samples collected in this study, only 2.75% smallholders in Jambi incinerate their residues. Hence, the fire breakouts happened on several provinces in Sumatera and Kalimantan in late 2019 did not happen due to crude palm oil waste-handling activities.

The analysis used modification of Rapfish method by using multidimensional scaling (MDS) technic [1]. The analysis of sustainability of rice farming in multidimensional revealed that rice farming carried out by farmers is less sustainable, with the sustainability index is 41.96. Indexs to the dimensions of ecological, economic, socio-cultural and technological sustainability are 48.25: 40.83: 40.97, and 16.46 respectively. This indexs indicate that ecological, economic, and socio-cultural dimensional were less sustainable, and index to the dimensions of technological was not sustainable. According to attribute leveraging analysis shows that there are some aributes as a leverage factor, ie: rice productivity, the usage of organic fertilizers, organic pesticides, and land capability class (for the ecological dimension); the percentage of income to total revenue, the percentage of farmers who live below the poverty line, farmer exchange, government subsidies, availability production facilities, comparative advantage, and the development of rice prices (economic dimension); farmers motivation, the average age of farmers, the adoption rate of technology, the time required for rice farming, rice consumption growth and government policy (socio-cultural dimensions); post-harvest technology, the availability of improved seed, the amount of rice milling, and how to eradicate the pest management (technological dimension).

This study aims to assess the status and utilization of R. apiculata, primarily by the fishermen community living near Muara Angke Wildlife Reserve in Jakarta Bay, Indonesia. The density of R. apiculata was determined by placing 100-meter-long transects from west to East in Muara Angke. While the normalized difference vegetation index (NDVI) of R. apiculata was studied using Landsat 8 satellite images with specific near-infrared and red wavelengths. The utilization of R. apiculata was assessed through interviews with 108 fishermen. The results showed that the west parts of Muara Angke had higher density, NDVI values, and canopy covers, with the R. apiculata density, NDVI, and canopy cover ranges being 3339.5-2856.3 Ha-1 trees, 0.79-0.99 percent, and 90-100 percent. There was a positive relationship between R. apiculata density, NDVI, and cover and the distance to the fishermen's village, decreasing NDVI trends toward villages. NDVI values in R. apiculata populations located far (> 1 km) from villages were higher, while NDVI values in R. apiculata populations located close (1 km) to villages were lower. Low density and NDVI values near the village were linked to fishermen's understanding and use of R. apiculata. This research can help to conserve and sustainably use the remaining mangrove community, primarily in Jakarta Bay.

The Indonesian government's intervention in suppressing forest fires is often carried out when massive fires have already occurred massively. When it happens in peat soil, forest fires become hard to extinguish because of the characteristics of burning below the ground surface, better known as the phenomenon of peat smoldering. Thus, that condition challenges the mitigation of forest fires in Indonesia to prioritize preventive principles in its implementation, one of which is through observing the physical condition of peatlands. This study examines and identifies existing regulations and policies concerning forest fires disaster mitigation by taking Riau Province as study area, one of Indonesia's areas that are, in many cases, hit by forest fires annually. Through the analysis of literature studies of relevant sources, this paper seeks to provide input on how monitoring the physi...
