Abstract

Carrying out maintenance on the distribution network is a series of actions or processes that aim to maintain the condition of the equipment so that it can function properly and prevent damage or disturbances that can interfere with the performance of the equipment. The focus of this study is on the maintenance of distribution substations by using a mobile substation unit that is synchronized with the substation to be carried out. The purpose of using this mobile substation unit is to avoid power outages or what is known as non-outage maintenance. Maintenance without blackout is the process of maintaining the substation without interrupting the supply of electricity to consumers. Where this maintenance is carried out in a state of tension. One of the distribution substation maintenance methods without blackouts is to transfer the customer load from the distribution transformer to the Mobile Substation Unit transformer. This research was conducted at PT. PLN (Persero) UP3 Kramat Jati by collecting data using the literature method, observation method, interview method. The results of this study found that PT. PLN (Persero) UP3 Kramat Jati performs two maintenance methods, namely preventive maintenance and corrective maintenance.

Pembuatan ekstrak meliputi maserasi kulit bawang putih metode maserasi dengan pelarut etanol 96% sdengan perbandingan 1000 gram:7,5 liter (1:7,5) selama 3x24 jam, setelah itu dilakukan penguapan menggunakan rotary evaporator setelah pelarut tidak menetes dilanjutkan pemekatan dengan waterbath hingga diperoleh ekstrak. Penelitian ini dilakukan secara in vivo selama 28 hari menggunakan 40 ekor bebek betina berumur 20 minggu yang sudah bertelur. Pemeliharaan empat perlakuan dan masing-masing 5 ulangan yaitu P0= sebagai kontrol tanpa tambahan ekstrak kulit bawang; P1= 98% ransum basal + 2% ekstrak bawang putih; P2= 96% ransum basal + 4% ekstrak bawang putih; P3= 94% ransum basal + 6% ekstrak bawang putih. Hasil yang diperoleh penambahan ekstrak kulit bawang putih tidak berpengaruh nyata menurunkan kadar kolestrol pada minggu ke-3 dan ke-4. Warna yolk berpengaruh nyata antar perlakuan dengan perlakuan kontrol didapatkan hasil bahwa perlakuan kontrol memiliki warna tergelap, sedangkan pada bobot yolk tidak berpengaruh nyata.
