<p><em>A power transformer is electrical power equipment that works to transmit power or electrical power from high voltage to low voltage or on the contrary. In the operation of distributing electricity, the transformer can be said to be the heart of transmission and distribution. In this condition, a transformer is expected to operate optimally according to its function.. If the isolation state of the transformer deteriorates, it can have an impact on operating failure and the most fatal of which is that the transformer is damaged which can cause disturbances in the electrical system. To overcome this, it is necessary to analyze the isolation resistance.</em></p><p><em>This study analyzes the isolation resistance on a transformer using the polarization index, tangent delta and oil breakdown voltage methods to determine the quality of the isolation on the transformer. This study took data at the 150 Kv substation Tegal. The data used include polarization index test data, tangent delta data, bottom oil breakdown voltage test data, and OLTC oil.

Tujuan dari penelitian ini adalah untk   menganalisis pelaksanaan e katalog dalam pengadaan barang/jasa pemerintah dan untk mengkaji pengaruh pelaksanaan e katalog dalam pengadaan barang/jasa pemerintah terhadap Usaha Mikro, Kecil dan |Menengah (UMKM). Seiring pertumbuhan ekonomi Indonesia yang pesat disertai dengan pengembangan otonomi daerah, kebutuhan pemerintah akan penyelenggaraan pemerintahan turut meningkat. Kebutuhan pemerintah akan pembangunan sarana dan prasarana dapat sebagai penyediaan pelayanan publik harus dilaksanakan melalui proses pengadaan barang/jasa, Metode penelitian yang digunakan adalah yuridis normatif. Pelaksanaan pengadaan barang/jasa pemerintah dengan e katalog   akan lebih terbuka, transparan dan efisien   dengan memangkas proses dan waktu dalam pengadan barang/jasa pemerintah. Pelaksanaan e katalog dalam pengadaan barang/jasa pemerintah berpengaruh pada sektor UMKM,   masih adanya pelaku industri kecil yang selama ini menjadi rantai distribusi barang/jasa. Melalui e katalog yang memutus rantai distribusi tersebut menyebabkan terhapusnya peran penyedia jasa kecil yang selama ini menjadi bagian dari rantai distribusi. Pemerintah telah mendorong pemanfaatan sistem e katalog   bagi UMKM, salah satunya adalah partisipasi UMKM dalam produk lokal e katalog. Pada pelaksanaanya pemanfaatan sistem e katalog bagi UMKM masih kurang, terbukti dengan masih minimnya pemanfaatan sistem e katalog oleh UMKM karena masih terbatasnya modal dan informasi terkait penggunaan sistem e katalog.
