Abstract

Abstract Agriculture is an important sector for Indonesia. Because around 30% of the population works in the agricultural industry. Currently, agricultural conditions in Indonesia are facing challenges due to climate anomalies. Unpredictable climate changes, shorter growing seasons, an increase in pests and diseases and these conditions have an impact on increasing production costs while yields are not optimal. Climate change is one of the obstacles in increasing plant productivity. The negative impacts of extreme global climate change include the degradation of land and water resources, damage to agricultural and irrigation infrastructure, the emergence of floods and droughts, and increased attacks by pests and plant diseases. Therefore, farmers need knowledge and farming skills that are adaptive to climate change or what is known as Climate Smart Agriculture (CSA). Climate Smart Agriculture is a useful approach to guide the actions needed to transform and reorient agricultural systems to effectively support development and ensure food security in conditions of climate change. CSA technology focuses on climate resilience and food security with the main objectives being: 1.) Increasing agricultural productivity and income in a sustainable manner, 2.) Adapting and building food security to climate change, 3.) Reducing and minimizing greenhouse gas emissions (Mitigation), 4.) Optimizing the use of various resources. So it is hoped that optimal results will be obtained in the agricultural sector. This research is qualitative research with a descriptive approach. The researchers use research data in the form of secondary data obtained from a number of credible sources such as scientific articles, books and a number of other sources that are credible and commonly used in research. These data were analyzed using analytical tools with stages of data collection, data selection, data reduction and drawing conclusions.

Abstract

Abstract Fuel oil (BBM) consumption in Indonesia has increased from year to year, but the availability of fuel oil will gradually become scarce. Bioethanol can be used as a substitute for fuel oil (BBM) depending on its purity level. Bioethanol is a liquid resulting from the fermentation process of sugar from carbohydrates which has good prospects as a liquid fuel with raw materials that are renewable, environmentally friendly and very profitable economically. Bioethanol can be used as a gasoline mixture for vehicle fuel and can be used as cooking fuel in households. The use of bioethanol can reduce CO gas emissions significantly. Bioethanol can be used directly as fuel oil or mixed into premium as an additive in a certain ratio (Gasohol or Gasoline alcohol). If mixed into gasoline, bioethanol can increase the octane number significantly. Bioethanol is known as an environmentally friendly fuel, because it is free from pollutant emissions. Bioethanol can be made from plant raw materials that contain starch such as cassava, sweet potato, corn, sago and molasses. One of the materials that can be used to make fuel from ethanol is the cassava plant. Cassava is a tuber that contains carbohydrates that come from the roots of the cassava plant. Cassava is very easy to plant and maintenance is not difficult. Cassava is usually used as a substitute for rice, but can also be used as an alternative to fuel oil. This research is qualitative research with a descriptive approach. Researchers use research data in the form of secondary data obtained from a number of credible sources such as scientific articles, books and a number of other sources that are credible and commonly used in research. These data were analyzed using analytical tools with stages of data collection, data selection, data reduction and drawing conclusions. Keywords: Fuel Oil, Bioethanol, Cassava

Abstract

Renewable energy planning is a complex process, involving multiple dimensions, including natural resource availability, government policies, and socio-economic factors. This study emphasizes the importance of a decision-making approach that is not only technically based, but also considers the social and political factors that influence policy implementation. Decision-making in renewable energy planning is often hampered by information inequality between stakeholders, social resistance, and policy instability that can slow down a sustainable energy transition. Multi-Criteria Decision Making (MCDM) methods have been used to help stakeholders choose the best option, but overly technical approaches can be a barrier in developing countries. Therefore, simpler and more data-driven approaches, such as heuristic models, become more relevant in contexts of uncertainty. This research uses a descriptive qualitative approach through case studies to explore the dynamics of decision-making in renewable energy planning. Data were collected through in-depth interviews, focus group discussions (FGDs), and document analysis. The results show that transparency, open communication and stakeholder participation are essential to overcome social and political barriers and support effective and sustainable renewable energy policy implementation.

Abstract

The increasing demand for electricity in urban areas of Indonesia demands diversification of sustainable energy sources. On-grid Solar Power Plants (PLTS) are a strategic alternative to reduce dependence on fossil fuels and increase household energy resilience. However, optimizing PLTS design still faces technical and structural challenges, such as the mismatch between panel production capacity and electricity consumption patterns, limited space, and weak regulatory support and fiscal incentives. This study uses a qualitative approach with a case study in an urban housing complex to examine the design process, implementation, and obstacles of on-grid PLTS. Data were obtained through in-depth interviews, field observations, and studies of policy and technical documents. The results of the study indicate that the success of PLTS implementation is highly dependent on a design that is contextual to the technical and social characteristics of housing, the support of fiscal policies such as initial subsidies, and institutional integration between communities, local governments, and the private sector. In addition, community-based approaches such as energy cooperatives can increase inclusive system adoption. This study concludes that on-grid PLTS is not only a technical solution for the clean energy transition, but also an instrument of socio-economic transformation that requires multidimensional synergy in its implementation in the urban environment of Indonesia

Abstract

Limited access to electricity in remote areas of Indonesia reflects complex structural issues, including geographic constraints, policy inequalities, and the low effectiveness of centralized approaches. Thousands of villages in the 3T (Disadvantaged, Frontier, and Outermost) regions still do not enjoy reliable electricity, hampering socio-economic development and reinforcing the cycle of poverty. Although Indonesia has great potential for renewable energy—such as solar and wind—its use is still minimal due to infrastructure constraints, investment, and non-contextual development approaches. In this context, a hybrid solar-wind energy system integrated with Internet of Things (IoT) technology offers an efficient and sustainable decentralized solution. IoT enables real-time monitoring, predictive maintenance, and data-driven energy management, which are critical in remote areas with limited technicians and physical access. This study uses a qualitative approach through a literature review to examine the challenges, potential, and policy relevance in developing IoT-based renewable energy systems. The results of the analysis show that transforming energy systems in marginalized areas requires not only technological innovation, but also a paradigm shift towards inclusive energy justice. Therefore, strengthening local capacity and integrating context-based policies are key to realizing a fair, reliable and sustainable energy system in Indonesia.

Abstract

ABSTRAK Program food estate Kabupaten Keerom, Papua, dikembangkan untuk mendukung ketahanan pangan, kebutuhan pakan ternak, dan peningkatan ekonomi petani lokal. Penelitian ini bertujuan menganalisis status keberlanjutan program food estate Keerom secara multidimensi serta mengidentifikasi faktor-faktor kunci yang memengaruhi prospek keberlanjutannya. Penilaian dilakukan menggunakan pendekatan Multidimensional Scaling dengan Rap-Industrial dan analisis prospektif terhadap lima dimensi, yaitu ekologi/lingkungan, ekonomi, sosial-budaya, teknologi dan infrastruktur, serta manajemen kelembagaan. Hasil penelitian menunjukkan bahwa program secara umum berada pada kategori kurang berkelanjutan. Dimensi teknologi dan infrastruktur merupakan aspek paling lemah, terutama terkait keterbatasan mekanisasi, irigasi, drainase, teknologi panen, dan sistem pendukung produksi. Meskipun hasil panen awal menunjukkan potensi produktivitas, keberlanjutan jangka panjang memerlukan penguatan kelembagaan, partisipasi masyarakat, pengelolaan lingkungan, dan kemitraan pasar. Temuan ini memberikan dasar strategis bagi perbaikan kebijakan food estate berkelanjutan di Papua. Kata kunci: food estate, keberlanjutan, MDS  ABSTRACT  The food estate program in Keerom Regency, Papua, was developed to support food security, livestock feed supply, and the economic improvement of local farmers. This study aimed to analyze the multidimensional sustainability status of the Keerom food estate program and identify key factors influencing its future sustainability. The assessment employed a Multidimensional Scaling approach using Rap-Industrial and prospective analysis across five dimensions: ecological/environmental, economic, socio-cultural, technological and infrastructural, and institutional management. The results indicate that the program is generally categorized as less sustainable. The technological and infrastructural dimension was identified as the weakest aspect, particularly due to limited mechanization, irrigation, drainage, harvesting technology, and production support systems. Although the initial harvest showed promising productivity, long-term sustainability requires stronger institutional arrangements, community participation, environmental management, and market partnerships. These findings provide a strategic basis for improving sustainable food estate policy and management in Papua. Keywords:  food estate, sustainability, MDS
