Techno-Economic and Social Analysis of Geothermal Development in Indonesia: A Case Study Approach

Indirect utilization of Geothermal resources in Indonesia is still very low compared to the existing potential, which is only around 2.36 GW (10.24%). In this research, the author conducted research using the Techno-Economic Analysis Method, which consists of several financial analysis tools, such as Net Present Value (NPV), Internal Rate of Return (IRR), and Discounted Payback Period (DPP), to determine the economic feasibility of geothermal development in the area under study. The author also looks at social aspects expected to provide an overview of the benefits for local communities around geothermal development projects. This research shows that if the developer only develops 55 MW, the project is considered unfeasible because the NPV shows negative results. However, if 110 MW is developed, it is feasible because the project provides positive results of USD 6,610,000 with a payback period of 25 years from the Commercial Operation Date (COD) and an IRR of 10.52%. From a social perspective, the positive benefit that will be directly received by the Government/community of producing regions is a production bonus with an average per year of USD 381,897 or around IDR 5.73 billion, assuming that 110 MW is developed

Co-Management in Mangrove Rehabilitation at Langkat Regency

Collaboration in the management of mangrove areas is a role for every social element in local government, the community, and the private sector. Co-management is an alternative solution in the form of management that integrates the roles and interests of everyone in the mangrove rehabilitation program. This study aims to analyze the role and level of influence of the interests of each actor in mangrove rehabilitation activities in Langkat Regency. The research method uses descriptive-qualitative data collected from the results of questionnaires, interviews; Field observations are processed in the form described in the description in the tabulation. From the results of this study, the form of joint management in mangrove rehabilitation is at a consultative stage where the government starts to consider local views in the decision-making process, the level of participation of each stakeholder is in a low category, so this Study recommends that the form of participation of each stakeholder can be improved through the form of joint regulations, sustainability programs and systematic work distribution that is disseminated to every implementer of mangrove rehabilitation programs in Langkat District

Evaluation of Land Suitability for Organic Horticulture Farming in Support of Sustainable Agrarian Governance

Abstract: Land compatibility can contribute to the optimization of agricultural land use, because this evaluation is used to determine the most appropriate spatial plan for current and future land use. Identifying the suitability of agricultural land is necessary to adapt to increasing food needs caused by expanding population, environmental pollution and climate change. Therefore, this research was conducted to assess the suitability of snake fruit plants. Various factors were considered in this research, such as rainfall, temperature, nutrient availability (wa), rainfall density (rc), organic carbon (nr), slope, flood hazard (fh) and erosion hazard (eh). The results of the classification of land suitability classes in the Sleman Regency area, in this case, are that snake fruit plants in most areas fall into the criteria for land suitability class S2 or quite suitable. The results are with an area of??42,150 Ha or with a percentage of 73.4% of the land suitability class S2 or Sufficiently Suitable. (Medium Suitable) is land that has quite heavy barriers to maintain the level of management that must be carried out. In the land suitability class S1 or very suitable in the research area with an area of?? 10625 Ha or with a percentage of 18.5, the land suitability class Very Suitable (Very Suitable) is land that has no boundaries. The results of the land suitability assessment, both actual and potential, can be carried out by improving efforts such as improving drainage, adding organic material, planting according to contours, fertilizing.

Empowering communities in mangrove ecotourism: A pathway to sustainability and climate resilience in Bengkulu City

This study examines how empowering local communities contributes to the planning, utilization, and management of Bhadrika Mangrove Ecotourism Park in Bengkulu City, advancing sustainability and climate resilience. Using a descriptive quantitative approach, 27 household heads from RT 08 Lingkar Barat were surveyed to assess their participation. The results indicate substantial community involvement in planning (73.03%), utilization (72.27%), and management (74.48%), all categorized as “good.” This active engagement promotes sustainable ecotourism, environmental preservation, and socio-economic development. However, issues such as limited infrastructure and low public awareness persist. Enhancing community roles through education, innovative approaches, and sustainable resource utilization is crucial to fully realize the ecological and social potential of mangrove ecotourism. The findings underscore the importance of community-driven initiatives in achieving ecosystem sustainability and climate change resilience

Analisis Faktor Internal dan Eksternal Proses Pengelolaan KHDTK Wanadipa Berbasis Peran serta Masyarakat dalam Fungsi Simpanan Karbon

Indonesia, salah satu negara yang memiliki hutan tropis terbesar di dunia dengan keanekaragaman jenis vegetasi yang sangat tinggi. Kawasan Hutan Dengan Tujuan Khusus (KHDTK) Wanadipa yaitu hutan pendidikan yang dikelola oleh Universitas Diponegoro dengan luas sebesar 99,65 Ha. Konflik penguasaan lahan antara pengelola kawasan tersebut dengan masyarakat yang tinggal di sekitar hutan, perubahan kebijakan pengelola hutan, serta minimnya partisipasi aktif masyarakat dalam proses pengelolaan KHDTK menjadi masalah yang sering kali terjadi di kawasan tersebut. Tujuan dari penelitian ini yaitu untuk menganalisis faktor internal dan eksternal dalam konservasi dan pengelolaan KHDTK Wanadipa berbasis peran serta masyarakat untuk meningkatkan simpanan karbon. Penelitian ini dilakukan di KHDTK Wanadipa, Kecamatan Ungaran Timur, Kabupaten Semarang. Metode yang digunakan pada penelitian ini dengan wawancara dan studi dengan Dokumen Rencana Pengelolaan Jangka Panjang KHDTK Universitas Diponegoro Tahun 2023-2043. Secara umum, proses pengelolaan KHTDK Wanadipa dipengaruhi faktor internal berupa program kegiatan KHDTK Wanadipa, serta manajemen kelembagaan. Selain itu, faktor eksternal berupa komunikasi dan koordinasi KHDTK Wanadipa dengan berbagai pihak, serta faktor alam. Berdasarkan hasil analisis SWOT, menunjukkan bahwa salah satu strategi pengelolaan KHDTK Wanadipa berbasis partisipasi masyarakat guna meningkatkan potensi simpanan karbon yaitu berupa melakukan kegiatan penanaman, khususnya mahoni yang bekerja sama dengan mitra serta melibatkan petani pesanggem di dalam pelaksanaannya

Mitigasi Bencana Masyarakat Pesisir Melalui Konservasi Mangrove di Kabupaten Langkat Sumatera Utara

Mangrove memiliki beragam peran dalam wilayah pesisir, selain memiliki fungsi ekosistem mangrove juga memiliki peran dalam proses mempertahakan wilayah pesisir dari beragam bencana alam serta memiliki nilai ekonomi dan sosial dari keberadannya. Selain berfungsi sebagai wilayah perawatan ikan dan penyedia layanan ekosistem mangrove juga memiliki peran sebagai pengatur yakni menjaga ketahanan pantai dari ombak. Fungsi mangrove sebagai bagian dari upaya mitigasi bencana yang terjadi di wilayah pesisir selama dua dekade terakhir. Kabupaten Langkat sebagai daerah pesisir merupakan wilayah rawan akan bencana diwilayah pesisir bergantung dari keberadaan tumbuhan penahan, mangrove memiliki peran sebagai penjaga wilayah pesisir dari masuknya air laut dan gelombang besar. Hal ini disebabkan karena sistem perakaran mangrove yang kuat dan memiliki struktur pengikat tanah yang baik. Akan tetapi saat ini kondisi kawasan mangrove di Kabupaten Langkat mengalami penurunan luasan lahan akibat berbagai peruntukan, Langkat berkontribusi sebesar 52% terhadap mangrove di Sumatera Utara. Dengan berkuruangnya jumlah luasan mangrove bepengaruh terhadap kondisi mitigasi bencana di pesisir langkat, penelitian ini bertujuan untuk menganalisis model struktur tanaman mangrove sebagai pemecah gelombang. Adapun metode yang digunakan adalah studi literatur dan observasi lapangan, adapun penelitian ini memperoleh hasil bahwa bentuk dan model formasi mangrove memberi gambaran tentang fungsi mangrove sebagai penahan ombak dan pemecah gelombang pada wilayah pesisir. Kata Kunci: Mitigasi Bencana; Konservasi Mangrove; Pengelolaan Lingkungan; Pesisir, Langka
