Abstract

Switching substations are usually supplied from one express feeder which can cause a low level of reliability due to disruption or outage on the express feeder. Also, the lack of power supply at the ends of the network causes voltage drops. One way to solve this problem is to reconfigure the network. In this study, testing was carried out on a distribution system in the Nagan Raya Regency, namely the distribution system of PT. PLN (Persero) ULP Jeuram originally had a radial system. Furthermore, the distribution system was reconfigured with the Krueng Isep hydroelectric power plant which was included in the PLN ULP Jeuram grid so that the system that was originally radial became a loop configuration. The method used in analyzing the network reconfiguration process is to use the ETAP 12.6 application. As a result, after reconfiguring the network the voltage increased from 19.2 kV to 20.7 kV, the highest increase was at the Beutong Substation which reached 1.5 kV and decreased power losses in the network with a total of 188.2 kW and 263.1 kVAR. Furthermore, before the network reconfiguration, ULP Jeuram SAIFI value was 22.25 times/customers and SAIDI values 1337.74 minutes/ customers. However, after reconfiguring the network, ULP Jeuram SAIFI value fell to 15.39 times/customers and SAIDI to 945.6 minutes/customers, resulting in an increase in system reliability by 70.69%.Keyword: Reconfiguration of network, distribution system, hydroelectric power plant, SAIDI, SAIFI

Abstract

Wind power is dominant energy converted into electricity through wind turbine generators used in wind energy conversion systems. Technological developments produce various types of generators for use in wind power plants of various scales. Permanent magnet generator (PMG) has advantage of being able to produce electrical energy of 500 watts at rotation 600 rotate per minute with an input wind speed of 2.5-12 m/s. The potential for average wind speed throughout the year in Aceh is around 1.5-6.5 m/s cannot be generate electric power because mechanical energy from turbine rotation is not sufficient to meet the minimum demand for RPM generators. The design of a horizontal axis wind turbine (HAWT) with Air Foil Naca 2410 is used to increase the efficiency of the turbine rotation. It’s influenced by variations in the number of blades and material used. Stages of simulation are prioritized to get efficient variations of the number of blades and the most effective material testing is performed. The results showed that variation of the axis of a three-blade wind turbine type has a higher coefficient of power that is 50 percent compared the other, the type of material wind turbines made from pinus more optimal than fiberglass.

Abstract

Naturally drying in the sun takes a very long time and product hygiene is also an obstacle because usually drying is done on open land. Using natural heat transfer, the time required for the coffee bean drying process ranges from 12-20 hours. The study describes a solar collector as an alternative device for drying in resulting coffee bean products with more hygienic without being exposed to dirt or bacteria. Shorter processes in which the quality of coffee beans increased were expected. The method used in this research is to analyze the heat absorption ability of the absorber using aluminium material which has been previously painted and the use of an air blower. The temperature inside was taken at thirty-minute intervals. Measurement of the mass of coffee beans was measured every 1-hour using digital scales. Similarly, mass and moisture content were also measured every 1 hour. From the results, it shows that the use of a blower with an airflow rate of 3.65 m/s with an average temperature of 56 ℃ can reduce the moisture content by 25.5%. For an air velocity of 4.55 m/s with an average temperature of 54.2 ℃, the moisture content reduces as much as 24.52%. Furthermore, for an airflow rate of 4.95 m/s with an average temperature of 52.7 ℃, the moisture decreased by 21.78% within 4 hours

Abstract

Inkubator merupakan salah satu penerapan secara tidak langsung energy panas untuk menetaskan telur puyuh sebagai pengganti induknya, daya tetas induk alami mencapai 90% sedangkan daya tetas dengan incubator mencapai 70% sampai dengan 80%. Dari pengamatan dan analisa hasil pengujian, variasi bola lampu dan daya yang digunakan sangat mmpengaruhi temperature ruangan incubator. Pengujian menggunakan empat lampu dengan daya 160 watt, enam lampu dengan daya 130 watt, dua lampu dengan daya 120 watt, empat lampu dengan daya 100 watt dan menggunakan menggunakan delapan lampu dengan daya 80 watt kurang efisien karena temparatur yang dihasilkan berkisar antara 40 0C sampai dengan 41,5 0C, kemudian pada pengujian menggunakan enam lampu dengan daya 90 watt temperature yang dihasilkan sangat seragam berkisar antara 39 0C sampai dengan 40 0C sehingga sudah sangat efisien unuk dilakukan pengujian penetasan. Berdasarkan hasil perhitungan, inkubator kecil dengan asumsi daya 60 watt yang digunakan selama 20 hari untuk menetaskan 78 butir telur puyuh membutuhkan energi total sekitar 28,8 kWh, atau 0,37 kWh per butir telur.Tingkat daya tetas yang diperoleh sebesar 78%, masih di bawah penetasan alami (±90%), namun sudah sesuai dengan kisaran inkubator skala rumah tangga (70–80%). Hal ini menunjukkan bahwa sistem inkubator sudah cukup baik, tetapi masih perlu peningkatan efisiensi dan pengaturan suhu agar hasil penetasan lebih optimal.
