Energy access is crucial for rural development in developing countries, as electrification drives economic growth, creates employment opportunities, and enhances the quality of life for rural communities. This study aims to determine the feasibility of powering a remote community with a hybrid energy system (HRS) combining solar photovoltaic, wind, and biogas to generate electricity and meet the energy needs of the rural area. West Waru Village was selected as the case study area due to its abundance of renewable energy sources. The HOMER tool was employed to model and optimize the HRS, providing a detailed analysis of its technical, economic, and environmental aspects. Furthermore, the study's findings were analyzed through a sensitivity analysis, considering uncertainty factors such as village load consumption, solar radiation, wind speed, and biomass availability. The best configuration for an on-grid scheme included a 2,284 kW photovoltaic (PV) system, 388 unit vertical axis wind turbine (VAWT), and a 500 kW biogas generator, resulting in a net present cost (NPC) of 8,506,090,acostofenergy(COE)of8,506,090, a cost of energy (COE) of 8,506,090,acostofenergy(COE)of0.054/kWh, and a payback period of 5.79 years. This configuration also reduced carbon dioxide (CO2) emissions by 67.2% compared to grid electricity. The optimal configuration for an off-grid scheme consisted of a 5,491 kW PV system, 954 VAWT, a 500 kW biogas generator, and 4,850 batteries, with an NPC of 20,162,390andaCOEof20,162,390 and a COE of 20,162,390andaCOEof0.1601/kWh, reducing CO2 emissions by 99.993%. These findings can serve as a baseline for the government to develop renewable energy systems in West Waru.

Several villages in Bone Bolango Regency are isolated because of geographical conditions and conservation reasons. There are no access road from paved road which can be used by PLN to installed grid. Several programs have been launched, including supply of electricity using renewable energy such as Micro hydro electric and solar cell, to help the villagers from blackout. Unfortunately most of installed power plants did not operate continuously since the human resources in the village is too weak to handle and maintain the sophisticated electrical instrument. Story of in Bone Bolango is not unique there are many similar stories in the entire Indonesia. To address why the ideal program of government is failing, we proposed this research which has ultimate aim to solve the existing problem in the society through research using transdisciplinary approach. Our starting location is Bone Bolango regency where we have been in contact for years. The first year of research is focused on framing the problems in the society through eyes of researchers (academics), government and people. The second year of research will be focused on transferring knowledge from each side to the others with aim to create goal oriented solution. Ones we have it in the third year, we will delivered that together (co delivered) and see what happen. The output research in every year is article published in peer reviewed and Scopus indexed journals and reputable international conference in Indonesia and Southeast Asia.
Socio-Economic Analysis of Renewable Energy Based on Community at Small Isolated Island in Indonesia
Conference: European Conference on Renewable Energy Systems, 2022
Indonesia as an archipelago country has thousands of islands. Some small-isolated islands do not have electricity access supplied by PLN (Indonesia Electricity Company). One of them is Selayar in South Sulawesi which cannot be reached by PLN due to terrain conditions where it is impossible to build the electricity distribution lines. This study aims to determine the potential of renewable energy sources that allow them to be used as electrical energy and reduce the shortage of electrical energy in the Selayar islands. The case studies were performed using HOMER software with various scenarios were investigated between solar, wind, and biomass. The lowest Levelized Cost of Electricity value is obtained for biomass and hybrid Solar-biomass, which are IDR1.496/kWh and IDR1.468/kWh. Between the two technologies, biomass is a technology that can be calculated both in terms of potential and price. In addition, Selayar islands can produce coconut around 21.170 tons/year. To support the government program called REBED (Renewable Energy Based Economic Development), briquettes can not only be used as a source of electrical energy but also can have an impact on the economy of the local community. By forming a briquette business unit, residents have job options and other abilities.

According to the International Energy Agency 2016 statistics, Ethiopia is among the lowest countries in annual electricity consumption, 70 KWh/capita. Rural areas hold more than 80% of the country‟s population and less than 30% of them have been electrified. Most of the population (the rural areas) still predominantly depend on traditional biomass energy sources for cooking and heating, and household lights are provided mainly by kerosene and biomass including this study area, Tadacha Rarasa, which consist of 4100 households with 6 members, totally 24,600 people[1, 2]. The feasibility study of hybrid system consisting of small Hydro, PV, Wind and Battery is carried out using HOMER as a tool for optimization and sensitivity analysis. TURBNPRO software also assists for the optimization of the small hydropower which is suggested to utilize the 2.2 m3/s ecological flow of the Genale 3 multipurpose hydropower plant‟s reservoir. The wind speed and solar radiation data of the site is colle...

Providing accessible, affordable and renewable electricity to rural areas in developing countries like Indonesia, is arguably challenging. The higher initial cost of renewable, as compared to conventional energy technologies, is often viewed as an obstacle in the rural electrification decision-making process. This study is conducted to examine the techno-economic feasibility of renewable energy generation options to bring electricity to the rural villages in Indonesia with Belu Regency, East Nusa Tenggara (ENT) as a case study. In this study, three village electrification scenarios were generated: basic (with the demand load of 150,5 kWh/day), moderate (359,9 kWh/day) and advanced electrification (579 kWh/day). To supply the load, three energy technologies were compared: conventional technology (diesel-powered); renewables technology (solar PV, and wind turbines); and hybrid technology (combination of diesel, solar PV and wind).

Proceedings of the Proceedings of the 13th International Interdisciplinary Studies Seminar, IISS 2019, 30-31 October 2019, Malang, Indonesia, 2020
This research presents the concept of developing Micro-hydro Resource with limited water discharge to become sustainable of Hybrid Renewable Energy System (HRES). Hybrid of Micro Hydro-Solar Photovoltaic (PV) energy sources and limiting the energy use of each household carried out simultaneously in both the rainy and dry seasons are the solutions so that not only electricity supply can be sustainable but also low cost. The operation of the Hybrid Renewable energy system is not as simple as using Micro-hydro resources so a Hybrid Optimization Model of Electric Renewable (HOMER) application program is needed. This application program is used to calculate the Total Initial Capital, Cost of Energy (COE) and Excess Energy from HRES. This simulation uses an application program that refers to the lowest Net Present Cost (NPC) value with a life time of 25 years. The simulation result shows that the lowest NPC value is Rp. 863,974,768, the Total Initial Capital needed to develop Micro-hydro Resources to become HRES in Ambapa village is Rp. 392,470,986,-. The contribution of energy produced from Micro-hydro energy sources is 103,780 kWh/yr (84.20%) and PV energy sources is 18,810 kWh/yr (15.8%). The 100% total contribution is 122,590 kWh/yr with COE of Rp1,107/kWh. The cost of electricity is Rp. 48,238/month with the energy consumption limits per household of 1,450 wh/day.
