Abstract

Penelitian ini bertujuan untuk membuat alat bantu pengambilan keputusan dalam mengoptimalkan pemanfaatan alternative fuel and raw material (AFR) di salah satu industri semen di Indonesia. Alat bantu pengambilan keputusan menggunakan model matematis mix integer linear programming. Model yang dikembangkan memiliki fungsi tujuan meminimalkan biaya produksi clinker, tetapi pada saat yang sama tetap menjamin empat aspek constraint meliputi: kualitas produk, kelancaran operasional pabrik dan kapasitas mengelola limbah, peraturan pemerintah dan emisi.
Model hasil pengembangan constraint aspek kualitas produk meliputi: lime saturation factor, silica ratio, alumina ratio, C3S, C2S, C3A, C4AF, predicted free CaO, MgO limit, Alkali equivalent. Model hasil pengembangan aspek plant operasional dan kapasitas mengelola limbah meliputi : chlorine – SO3, Alkali to SO3 ratio, coating index, kapasitas TPS limbah B3, kapasitas feeding AFR, material availability. Aspek peraturan pemerintah meliputi : batasan logam berat dan umur limbah. Aspek lingkungan meliputi emisi TOC (Total Organic Carbon) dalam CH4.
Model hasil pengembangan kemudian dijadikan dasar pembuatan formulasi pada Decision Support System (DSS). DSS memiliki fitur tampilan dalam bentuk dashboard dan parameter dialogue modelling untuk memudahkan interpretasi dan simulasi beberapa skenario. Model selanjutnya diuji untuk mengevaluasi 8 jenis bahan baku alternatif dan 10 jenis bahan bakar bakar alternatif. Berdasarkan hasil simulasi diperoleh rekomendasi optimal jenis LB3 yang dimanfaatkan sebanyak 6 jenis bahan baku alternatif dan 3 jenis bahan bakar alternatif dengan tetap memenuhi aspek spesifikasi kualitas produk, kelancaran operasional, compliance dan environmental, dengan potensi penghematan biaya bahan baku dan bahan bakar untuk memproduksi clinker sebesar 39% per hari.
====================================================================This study aims to make a decision-making tool in optimizing the use of alternative fuel and raw material (AFR) in one of the cement industries in Indonesia. The decision tool uses a mixed integer linear programming mathematical model. The model developed has the objective of minimizing clinker production costs, while at the same time ensuring four constraint aspects including: product quality, smooth factory operations and capacity to handle waste, government regulations and emissions limit.
The resulting model of product quality constraint development consist of: lime saturation factor, silica ratio, alumina ratio, C3S, C2S, C3A, C4AF, predicted free CaO, MgO limit, Alkali equivalent. The model results of the development of operational plant aspects and waste management capacity consist of: chlorine — SO3, Alkali to SO3 ratio, coating index, hazardous waste storage capacity, AFR feeding capacity, material availability. Aspects of government regulations consist of: limits on heavy metals and the expired date of the waste. The environmental aspects consist of TOC (Total Organic Carbon) emissions in CH4.
The development result model is then used as the basis for the formulation of the Decision Support System (DSS). The DSS has features a dashboard and a dialogue modeling parameter for easy interpretation and simulation of several scenarios. The model is then tested to evaluate 8 types of alternative raw materials and 10 types of alternative fuels. Based on the simulation results, the optimal recommendation for the type of hazardous waste to be utilized is 6 types of alternative raw materials and 3 types of alternative fuels while still meeting the aspects of product quality specifications, operational smoothness, compliance and the environment, with the potential for saving on raw material and fuel costs to produce clinker is 39% per day.
