Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Environmental factors play a significant role in determining the PV system's performance, and the temperature is one factor. In the highland area, the temperature is lower than lowland but with relatively the same amount of irradiance. This paper compares the PV system's performance in the highlands (Semendo Darat Ulu) and the lowlands (Tanjung Enim). Semendo Darat Ulu has an elevation of 1100 meters above sea level and a temperature of ± 28.1 °C, sufficient for implementing solar power plants. Experimental data shows that Semendo Darat Ulu's PV system delivers better performance than Tanjung Enim's PV system. The average power generated by the PV system installed in Semendo Darat Ulu is 32.98 W, 4.21 W, or 115% higher than Tanjung Enim's PV system. It produced average power of 343.88 W per day, which is 77.99 W or 129 % more than the power produced by the PV system in Tanjung Enim. In Semendo Darat Ulu, the PV system pumped a total of 140,669 liters of water during the experiment, which means 33,915 liters or 132 % more water pumped by the PV system Tanjung Enim. Therefore, Semendo Darat Ulu highland has more potential for applying solar power plants than the lowland area.
Gambiran II springs that come from within the forest area are natural resources that are utilized not only to meet the needs of the surrounding people but also to ensure the needs of creatures in the forest. The flow of springs that continue to decline from year to year is inversely proportional to the population that utilizes increasing water so that it is necessary to identify the factors that cause the decline in discharge and sustainable water utilization solutions with increased consumption. Local community today utilize the entire flow of discharge springs for their needs so as to potentially cause problems of unsustainable utilization because they do not pay attention to the social, economic and ecological dimensions. Identification of factors that cause decreased discharge from rainfall parameters and land closures become the starting point for efforts to improve management and solutions of dynamic system approaches designed to look at future projections of water usage quantity that pay attention to social, economic and ecological dimensions. Dynamic system scenarios are predicted to support sustainable water management if the quantity of water used is 50% of the flow discharge and the community lowers a capita consumption of water according to the standard of various water needs.
