Abstract

Pemerintah dalam rangka mewujudkan program ketahanan pangan nasional memberikan penugasan pada PT Petrokimia Gresik yang merupakan industri pupuk terlengkap di Indonesia untuk memenuhi kebutuhan pupuk nasional. Pupuk jenis ZA merupakan salah satu jenis pupuk bersubsidi yang hanya diproduksi oleh PT Petrokimia Gresik. Hal tersebut menyebabkan PT Petrokimia Gresik bertaggungjawab dalam menjaga kelancaran produksi agar dapat memenuhi permintaan terhadap pupuk ZA secara tepat waktu, jumlah dan kualitas. Kelancaran produksi dapat dipengaruhi oleh stabilitas dan kelancaran persediaan bahan baku. Permasalahan yang terjadi pada persediaan bahan baku pupuk ZA di PT Petrokimia Gresik yaitu adanya stockout. Sehingga dibutuhkan suatu perencanaan kebutuhan bahan baku yang tepat, maka pada penelitian ini akan dilakukan analisis perencanaan kebutuhan bahan baku produksi pupuk bersubsidi jenis ZA yang dimulai dengan melakukan peramalan permintaan pupuk ZA periode 2018 menggunakan metode ARIMA Box-Jenkins. Setelah itu dari peramalan tersebut dilakukan penyusunan perencanaan kebutuhan bahan baku dengan menggunakan Material Requirement Planning. Hasil analisis diperoleh bahwa model terbaik untuk meramalkan permintaan pupuk bersubsidi jenis ZA I atau ZAIII dan ZA II adalah ARIMA (0,0,1)(0,0,1)12. Permintaan pupuk paling banyak terjadi pada bulan Maret sedangkan terendah pada bulan Desember 2018. Perencanaan kebutuhan bahan baku periode 2018 untuk jenis pupuk bersubsidi ZA I atau ZA III sebanyak 247.660 ton sedangkan pupuk bersubsidi ZA II sebanyak 446.600 ton. ============================================================ The government in order to realize the national food security program assigned to PT Petrokimia Gresik which is the most complete fertilizer industry in Indonesia to meet the needs of national fertilizers. ZA fertilizer is one type of subsidized fertilizer produced only by PT Petrokimia Gresik. This causes PT Petrokimia Gresik to be responsible in maintaining the smoothness of production in order to fulfill the allocation of fertilizer subsidy from the demand to ZA fertilizer in a timely manner, quantity and quality. Smooth production can be affected by the stability and smooth supply of raw materials. Problems that occur in inventory of raw material of ZA fertilizer in PT Petrokimia Gresik is stockout. So that needed a proper requirement planning of raw materials, hence in this research will be done analysis of requirement planning of raw material of production of ZA fertilizer subsidy which started by forecasting demand of ZA fertilizer period 2018 using ARIMA Box-Jenkins method. After that from the forecasting is done preparation of raw material needs planning by using Material Requirement Planning. The result of analysis shows that the best model to predict the demand of subsidized fertilizer of ZA I or ZA III and ZA II is ARIMA (0,0,1) (0,0,1) 12. The most fertilizer demand occurred in March while the lowest was in December 2018. Planning of raw materials for the period of 2018 for the type of subsidized ZA I or ZA III fertilizer is 247,660 tons while the ZA II subsidized fertilizer is 446,600 tons.
