To improve the reliability of electric power systems, PT. PLN Area Semarang use Recloser on the electricity network. Nowadays, the determination of recloser position is very important in reliability of electrical power system. Reliability index used in distribution systems are SAIFI and SAIDI. The value of SAIFI and SAIDI can be calculated from the outage time and the failure rate occurred in one year. Reliability can be concluded better if SAIFI and SAIDI smaller. This research aims to determine the optimal placement of recloser location on the electrical network in feeder PDP 03 Pudak Payung substation. The method used for the recloser location placement is Ant Colony Optimization (ACO) using Matlab Software R2014a. From simulation result, it can be concluded that the reliability value before and after placement recloser changed. SAIFI and SAIDI before recloser placement is 1.0172 times/year and 2.5435 hours/year. Optimal placement location for 1 recloser is at a location 4 with a value of SAIFI and SAIDI is 0.3361 times/year and 1.0456 hours/year. While for 2 reclosers is at a location 2 and 7 with a value of SAIFI and SAIDI is 0.26755 times/year and 0.86069 hours/year.","PeriodicalId":23662,"journal":{"name":"World Academy of Science, Engineering and Technology, International Journal of Nutrition and Food Engineering","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86110944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metode penelitian yang digunakan dalam penelitian ini adalah penelitian normatif dengan pendekatan penelitian pendekatan perundang-undangan dan pendekatan kasus. Jenis bahan hukum terdiri dari bahan hukum primer, bahan hukum sekunder dan bahan hukum tersier. Teknik dan alat pengumpulan data yang digunakan adalah studi kepustakaan dan studi dokumen. Berdasarkan hasil penelitian yang diperoleh, dapat disimpulkan bahwa kepastian hukum atas kriteria merek terkenal dan persamaan pada pokoknya secara substantif sudah diatur jelas pada penjelasan Pasal 21 Undang-Undang No. 20 Tahun 2016 Tentang Merek dan Indikasi Geografis. Upaya hukum yang dilakukan oleh pemilik merek terkenal untuk memperoleh perlindungan hukum adalah dengan mengajukan gugatan apabila ada yang melanggar hak eksklusif yang dimiliki. Dalam sengketa merek Gudang Garam dan Gudang Baru terdapat perbedaan pertimbangan hukum hakim, Putusan Kasasi No.162 K/Pdt.Sus-HKI/2014 dalam penegakannya tidak memberikan kepastian hukum karena Gudang Garam secara normatif telah memenuhi kriteria sebagai merek terkenal dan Gudang Baru terbukti memiliki itikad tidak baik dan persamaan pada pokonya dengan Gudang Garam.

Bahan baku utama yang diolah dalam peleburan yang berbahan dasar besi-besi tua (scrap) dan beberapa bahan campuran tambahan lainnya. Proses peleburan dilakukan pada stell melting shop (SMS) menggunakan alat EAF (Electrical Arc Furnace) yang menghasilkan bahan setengah jadi yaitu billet. Billet yang sudah jadi kemudian dipanaskan ulang pada billet reheating furnace (BRF) yang akan di roll pada rolling mill plant (RML) yang akan menghasilakan wire rod. BRF memiliki tiga zone yaitu pre heating, heating, dan soaking dengan suhu yang berbeda – beda. Dalam satu jam BRF dapat memproduksi 36 billet. Penelitian ini menggunakan failure modes and effect analisys (FMEA) dalam mengidentifikasi bentuk kegagalan dan effek kegagalan dari komponen utama BRF. Kemudian dalam pemilihan jadwal perawatan yang optimal menggunakan reliability centered maintenance (RCM II). Analisa kuantitatif akan dimasukkan dalam penentuan interval waktu perawatan optimal dengan memperhatikan biaya perawatan (CM) serta biaya kerusakan (CR).
