Abstract
Proteksi pada sistem kelistrikan industri bertujuan untuk mengurangi kerusakan peralatan akibat adanya gangguan yang dapat menginterupsi sistem kelistrikan. Proteksi pada industri harus terkoordinasi dengan baik sehingga lama waktu terjadinya gangguan dapat dibatasi. Proteksi pada sistem kelistrikan dapat diatur dengan menggunakan rele proteksi. PT Solusi Bangun Indonesia Tbk sebagai perusahaan yang bergerak dibidang produksi semen juga membutuhkan koordinasi proteksi yang baik. PT Solusi Bangun Indonesia Tbk memiliki permasalahan yang sebelumnya dalam proses produksi ketika terjadi gangguan pada salah satu titik beban akan mengakibatkan CB open pada titik beban diatasnya, sehingga menyebabkan terjadi dampak pemadaman yang cukup luas saat proses produksi. Sehubungan hal tersebut diperlukan evaluasi koordinasi proteksi yang tepat sehingga pabrik beroperasi secara maksimal dan handal dalam mengatasi gangguan.
Dari hasil plot koordinasi kurva arus waktu kondisi existing setting koordinasi rele arus lebih fasa masih ada kesalahan koordinasi sehingga perlu dilakukan evaluasi ulang untuk mendapatkan hasil resetting yang bisa direkomendasikan sebagai setting rele pengamannya. Melalui hasil analisis dan perhitungan manual direkomendasikan penyetelan pick up rele arus lebih dan penyetelan grading time. Rele yang disetel ulang adalah rele arus lebih gangguan fasa (overcurrent relay).

Protection in industrial electrical systems aims to reduce equipment damage due to disturbances that can interrupt the electrical system. Protection in industry must be well coordinated so that the duration of disturbances can be limited. Protection in the electrical system can be adjusted using a protection relay. PT Solusi Bangun Indonesia Tbk as a company engaged in cement production also requires good protection coordination. PT Solusi Bangun Indonesia Tbk had problems pREFiously in the production process when a disturbance at one of the load points would result in CB open at the load point above it, causing a fairly wide blackout impact during the production process. In connection with this, it is necessary to evaluate the proper protection coordination so that the factory operates optimally and reliably in overcoming disturbances.
The results of time current curve in exisiting conditions can be seen that there are misscoordination more phase relay current so that need to re-evaluate to get resetting result which can be reommmended as relay security setting. Through the analysis and manual calculation result, give the recommendation to reset pick up setting and grading time of overcurrent relays. Relays that need to be reset are phase fault overcurrent relays.
