Abstract

Indonesia sebagai negara yang terletak di wilayah garis Khatulistiwamemiliki potensi penyinaran 12 jam setiap hari sepanjang tahun. Semakin menipisnyacadangan minyak bumi membuat manusia harus mencari energi yang terbaharukan.Solar sel merupakan sebuah alat yang dapat mengkonversi energi cahaya menjadienergi listrik. Penggunaan solar sel telah berkembang dalam berbagai bidang industriantara lain sebagai pendorong kegiatan ekonomi dan bahkan kebutuhan transportasi.Pada penelitian ini, solar sel digunakan sebagai sumber penggerak perahumenggunakan motor dc. Motor dc yang digunakan 0,9 Hp dengan 5 pengaturankecepatan maju dan menggunakan perahu fiber kayu dimensi 8,2m x 0,75m x 0,7m.Hasil penelitian bahwa beban maksimum pada pengaturan kecepatan 5 dengan beban4 orang (265 kg). Kecepatan maksimum 6,37 km/jam dan dapat bertahan hingga 2jam 22 menit menggunakan baterai 100Ah. Dari pengujian, aplikasi ini dapatditerapkan dan bahkan dikembangkan dengan daya motor yang lebih besar.

Abstract

The development of population from time to time is increased and the need for electricity consumption is also increased. Simultaneously increasing the need for electric power requires the provider of electricity supply in this case PT. PLN (Persero) should deliver power effectively to consumers. To maximize the distribution of electricity to the consumer, a load planning is required. This load planning is conducted to find out how much amount of power is required by consumer. The purpose of this research is to investigate the need of power load of interconnection system of South Sulawesi and to investigate the accuracy of load planning using Artificial Neural Network (ANN) backpropagation.

Abstract

The heat rate is a parameter that can indicate the reliability of the Steam Power Plant and is defined as the amount of heat from the fuel needed to produce 1 kWh of electricity. This study aims to analyze the effect of load changes on heat rate and its optimum value. Heat rates can be expressed in GPHR (Gross Plant Heat Rate) and NPHR (Net Plant Heat Rate). The method used is to identify and collect data for the last three years related to the determination of the heat rate, then perform data processing and analysis. In 2018, the optimum condition for unit 1 was obtained at a load of 125 MW is NPHR 2432.68 kcal/kWh, while Unit 2 at a load of 135 MW is NPHR value of 2489.65 kcal/kWh. In 2019 the optimum value for NPHR units 1 and 2 at a load of 137 MW are NPHR 2517.07 kcal/kWh and NPHR 2527.48 kcal/kWh, respectively. In 2020 the optimal value for Unit 1 is at a load of 135 MW, NPHR 2529.5 kcal/kWh, while Unit 2 is at a load of 137 MW, NPHR 2567.53 kcal/kWh. It can be concluded that an increase in load causes a decrease in the heat rate

Abstract

Indonesia, as one of the world’s largest palm oil producers, requires an efficient and environmentally friendly transportation system for fresh fruit bunches (FFB). In many plantations, the transportation process is still carried out manually or using fossil-fuel-based vehicles, which increases operational costs and contributes to carbon emissions. This study aims to design and develop a solar power plant (PLTS)-based electric rail cart prototype for transporting palm oil fresh fruit bunches. The research method consisted of field surveys, system planning and design, prototype fabrication and assembly, and performance testing. The drive system utilizes a 48 V, 500 W DC motor connected through a chain, sprocket, and pulley–V belt transmission with a 1:9 gear ratio. Electrical energy is supplied by a 460 Wp solar photovoltaic system and stored in a 48 V, 120 Ah battery. Performance testing was conducted for five days to evaluate photovoltaic efficiency, DC motor efficiency, and overall system efficiency under different load conditions. The results showed that the maximum photovoltaic efficiency reached 16.23%, while the DC motor efficiency achieved 81.10% at a load of 400 kg. The maximum overall system efficiency was recorded at 68.24% at a load of 150 kg. Under a 400 kg load condition, the system was able to operate for approximately 3 hours until the battery capacity reached the minimum discharge limit of 20%. These results indicate that the implementation of a solar-powered electric rail cart has strong potential as an efficient and environmentally friendly transportation solution for palm oil plantations while supporting the utilization of renewable energy in the agricultural sector.
