Abstract

Jeneponto Regency in South Sulawesi possesses significant wind potential, making it an ideal location for the development of Wind Power Plants (WPP). However, these WPPs are intermittent due to the inconsistent nature of wind energy, presenting challenges that affect the performance and efficiency of turbines in generating electricity. Therefore, this study aims to evaluate the performance of the SWT-3.6-130 wind turbines at the Tolo 1 WPP in Jeneponto to determine their capability in converting wind energy into electrical energy at specific wind speeds. The evaluation results indicate that the performance of the SWT-3.6-130 wind turbines at the Tolo WPP in February 2022 was not optimal. The maximum output power generated by these turbines approached the maximum capacity of 3.6 MW, with Turbine 06 producing 3.57 MW at a wind speed of 13.07 m/s, Turbine 09 producing 3.57 MW at a wind speed of 12.27 m/s, and Turbine 013 producing 3.58 MW at a wind speed of 12.11 m/s. Although the power generated was close to the maximum capacity, the performance variation among turbines indicates the need for further evaluation to address factors reducing efficiency. Power coefficient analysis shows that Turbine T13 exhibited the best performance, with the fewest instances of power coefficient values not meeting standards. This study provides crucial insights for improving performance and preventing failures at the Tolo WPP in the future.

Abstract

Agriculture is a key sector of the Indonesian economy, with shallots being one of the most important commodities. However, limited access to electricity in rural areas is often a barrier to the implementation of efficient irrigation systems. This research focuses on developing an automatic shallot irrigation system using a solar pump. The system is designed by using solar panels to convert solar energy into electricity to power the water pump. They use an Arduino-based control system integrated with a real-time clock (RTC) to automatically set the watering schedule so that plants can be watered at the right time without human intervention. Tests were conducted on 96 m² of land to evaluate the performance of the automation system, energy efficiency, and system performance under actual operating conditions. The testing results show that the system can operate efficiently, with the solar panel generating enough energy to power the pump and maintain watering continuity. The system can reduce dependence on conventional electricity, providing a sustainable and environmentally friendly irrigation solution. As such, the system provides an effective solution for agricultural systems in areas with limited access to electricity, while supporting the use of renewable energy.

Abstract

This study aimed to examine the effect of social andenvironmental performance’s disclosure on financial performance incompanies listed on the Stock Exchange under energy, mining and infrastructure industry sectors during 2010-2013.Using multiple regression method, the results show that environmental and social performance impact on the financial performance simultaneously while partially none of the independent variables affect the dependent variable. But the positive direction of their relationship is congruent with the theory. That is the better environmental and social performance then the better the financial performance.

Abstract

This study aims to analyze trends, scientific contributions, and collaborations in financial literacy research in Southeast Asia using bibliometric methods. A total of 635 documents from the Scopus database, published between 2009 and 2024, were analyzed through co-citation, keyword co-occurrence, and bibliographic coupling techniques using VOSviewer. The analysis identified key contributors, leading affiliations, countries, and emerging research themes in the field. Results show a significant increase in publications, particularly after 2021, peaking in 2023. Indonesia and Malaysia emerge as the leading contributors, with Universiti Malaya and Universiti Teknologi MARA being prominent institutions. Malaysian authors, particularly Sabri, MF, dominate the region’s research landscape, while Indonesia leads in overall contributions. Themes such as financial behavior, Islamic financial literacy, fintech, and financial education are prominent, reflecting the growing complexity of financial literacy in the digital age. Notably, international collaborations involving Southeast Asian researchers with counterparts in the United States, the United Kingdom, and Germany underscore the global attention this field is attracting.this study emphasizes the need for enhanced cross-country and multidisciplinary collaboration to address financial literacy disparities in southeast asia. The findings are expected to inform targeted policies, foster innovation, and strengthen regional financial education initiatives, ultimately contributing to economic stability and inclusion in Southeast Asia.

Abstract

There are several types of photovoltaic system configurations, one of which is the on-grid PV system. This system is simple compared to other systems. Because there are two different energy sources that can supply the load either together or separately, an analysis of how the irradiation affects the electrical parameters on the load side or the grid itself is required. The goal of this research is to examine the performance of on-grid PV under various irradiation variation, type, and load power to power factor, grid frequency, and load conditions. To measure the performance of on-grid PV, parameter calculations are carried out in the form of PV efficiency, final yield, reference yield, and performance ratio, and the results of measurements of power factor, grid frequency, and load are observed due to variations in irradiation, type, and load power. The results show that the performance of on-grid PV is good; low irradiation can result in a decrease in the grid power factor, while the grid and load frequencies are in normal conditions for various variations of irradiation, type, and load power.

Abstract

The Wae Tuoe Fishermen Group in Pinrang Regency is a coastal community located in Suppa District, Pinrang Regency, South Sulawesi Province, where the majority of the population relies on marine resources for their livelihood. The bagang is a structure made of wood or bamboo located in the middle of the sea, about 500 meters to 2 kilometers from the shore, used by fishermen to catch or store fish. The bagang has great potential but is not optimally utilized by fishermen as a source of livelihood and economic improvement. This is because the fish catch is maximized at night. The limited lighting, which could help optimize the fishing process, is due to the restricted availability of electricity from generators. The development of solar cell technology, which can generate and store electricity, is a new breakthrough in the use of renewable energy. The use of solar cells is expected to provide an energy source for lighting on the bagang, allowing fishermen to maximize their activities at night. The solar cell lighting system is designed to supply six light points with a capacity of 5 x 50 watts operating at night from 7:00 PM to 4:00 AM. The design of the PLTS, which consists of two solar panels with a capacity of 550 Wp, four 12 V batteries with a capacity of 100 Ah, and a 1000-watt inverter, is expected to provide electricity as a lighting source for the bagang during the night. After conducting counseling and training on solar power plant (PLTS) technology, 18 out of 20 members of the Wae Tuoe Fishermen Group gained knowledge about the utilization, design, installation process, usage, and maintenance of PLTS technology.

Abstract

Teachers at SD Negeri Pundungrejo 03 have difficulty implementing differentiated learning and tend to use existing learning devices without modification. This community service activity aims to improve teachers' ability to implement the differentiated Independent Curriculum with the Teaching at the Right Level (TaRL) and Culturally Responsive Teaching (CRT) approaches. This activity was carried out directly at SD Negeri Pundungrejo 03 Sukoharjo. The community service implementation procedure refers to the APTE stages (Needs Analysis, Training and Mentoring, Action, and Evaluation). The pretest results showed that teachers' initial understanding of the development of TaRL and CRT-based learning devices was still low. However, after mentoring, the posttest results showed a significant increase in teacher knowledge and skills. Indicators of success can be seen from the ability of teachers to develop learning devices according to students' thinking levels and their cultural backgrounds. Teachers also showed high enthusiasm in improving the quality of the learning process.
