Abstract

PT. Perkebunan Nusantara X merupakan salah satu produsen gula di Indonesia yang berkantor pusat di Surabaya. PT. PN X juga memiliki usaha bioetanol yang berada di kawasan salah satu unit usahanya yaitu di pabrik gula Gempolkrep, Mojokerto. Dimana pabrik bioetanol ditargetkan dapat memproduksi 30.000 KL bioetanol per tahunnya. Untuk menunjang produksi tersebut, sistem kelistrikan pabrik bioetanol diintegrasikan dengan sistem kelistrikan pabrik gula Gempolkrep. Hal ini tentunya berpengaruh terhadap sistem proteksi pabrik bioetanol terutama apabila terjadi gangguan yang menyebabkan nilai arus hubung singkat menjadi lebih besar. Hasil analisa dan simulasi koordinasi proteksi pada sistem kelistrikan pabrik bioetanol PT. PN X menunjukkan bahwa kondisi existing setting koordinasi rele arus lebih fasa masih ada beberapa kesalahan koordinasi pada setting pickup dan time delay serta peralatan pengaman (fuse) yang tidak dapat mengisolasi gangguan dengan tepat. Melalui tugas akhir ini, dilakukan resetting rele pengaman dan penggantian fungsi pengaman fuse menjadi rele arus lebih. Dari hasil tersebut, direkomendasikan resetting koordinasi yang tepat untuk sistem kelistrikan pabrik bioetanol PT. PN X. ======================================================================================================================== PT. Perkebunan Nusantara X is one of sugar producer in Indonesia which is headquartered in Surabaya. PT. PN X also has a bioethanol business in the area of one of its business units, namely Gempolkrep sugar factory, Mojokerto. Where the bioethanol factory is targeted to produce 30,000 KL of bioethanol per year. To support the production, bioethanol factory electrical system is integrated with the Gempolkrep sugar factory electrical system. This is certainly affect the bioethanol factory protection system, especially if there is a fault that causes the value of short-circuit current becomes greater. The results of the analysis and simulation of the electrical system protection coordination bioethanol factory’s PT. PN X shows that the existing condition of phase overcurrent relay coordination setting there are still some coordination errors on pickup and time delay settings and safety equipment (fuse) which can not isolate a fault appropriately. Through this final project, carried resetting the safety relay and fuse replacement safety function becomes overcurrent relays. From these results, it is recommended the proper coordination resetting of the electrical system bioethanol factory’s PT. PN X.
