Abstract

Power system distribution, reliability and stability of the system is very important in order to provide convenience in service to consumers. This can be fulfilled by paying attention to the condition of the existing power equipment. One of the most important equipment in power system operation is transformer. Distribution transformers will work optimally if the electrical load carried in the transformer network area does not exceed the capacity of the distribution transformer. When there is an overload on a transformer, the insulation inside the transformer becomes overheated due to the current loaded on the transformer is very large or exceeds the nominal current of the transformer. The solution to overcome the overload on the transformer is if the location between transformers is far apart, it can be done by inserting the transformer by referring to the transformer rating that will supply the load. If the load supplied by the transformer on the network is getting bigger, then a transformer with a large capacity is used to supply the large load, otherwise the transformer will experience an over load which can cause the transformer to trip. At the KTAEXK007 and KTAEXK009 substations, both load shifting is carried out to one of the nearest transformers, namely the KTAEXK008 Amans Hotel substation. Then in the existing calculations, there are two transformers that will be used for transformer insertion, namely a transformer with a rating of 315 kVA and a 100 kVA transformer.

Abstract

Proses pengeringan ikan alami mempunyai kendala di antaranya pengeringan lama, memerlukan tempat luas, gangguan lalat apalagi pada musim hujan yang membuat terkendala dalam proses pengeringan. diantaranya pengeringan dengan sinar matahari atau biasa disebut pengeringan secara tradisional dilakukan dengan menjemur ikan sampai ± 3 hari jika cuaca cerah dan membalik ikan 4-5 kali agar pengeringan merata. Menggunakan pengering dengan elemen pemanas  pada bagian belakang alat pengering ikan sistem oven, sehingga pengeringan ikan dapat berjalan dengan baik. Metode yang digunakan untuk menyelesaikan penelitian ini adalah Riset and Development (riset dan pengembangan) yaitu suatu metode yang dipakai untuk mengembangkan model alat.  Pengujian hari pertama dengan interval waktu 5 menit di mulai waktu 0 menit sampai 65 Menit, Temperatur suhu naik mulai dari 29,7 sampai 65,1 ᵒC (derajat celcius). Tegangan fluktuatis dari 210 V sampai 214 V, Arus Konstan berada pada 1,55 A, Daya naik mulai dari 322 watt sampai 332 watt, Konsumsi Energi Naik mulai dari 1028 sampai 1578, Kondisi ikan basah berangsur angsur mulai mongering. Pengujian hari kedua dengan interval waktu 5 menit di mulai waktu 0 menit sampai 60 Menit, Temperatur suhu naik mulai dari 29,8 sampai 46,5 ᵒC (derajat celcius). Tegangan fluktuatis dari 214 V sampai 212 V, Arus Konstan berada pada 1,56 A, Daya naik fluktuatif dari 335 watt sampai 330 watt, Konsumsi Energi Naik mulai dari 1610 sampai 2468, Kondisi ikan mulai kering berangsur-angsur mengering.
