Pemodelan Sistem Pengelolaan Limbah Untuk Mengoptimalkan Siklus Limbah Plat Besi di PT. Maxima Daya Indonesia

Abstract

Waste is still a problem that still has to be studied and understood in its management so that it does not accumulate and lead to fatal conditions in the environmental ecosystem. Therefore, this study was made with the aim of finding the factors causing the accumulation of iron plate waste at PT. Maxima Daya Indonesia to create a waste management strategy by maximizing the sale of waste inventory in the waste collection warehouse. This research is a descriptive study using dynamic systems research methods and looking for scheduling by calculating the ROP, then found 3 strategies to be compared to choose the one that is more optimal and efficient. The results of this research are 1. The problem of this research lies in the time of the initial waste sale, 36 working days which exceeds the volume limit of the waste container (1000 kg). 2. Scheduling strategy by finding the resulting ROP there are three, namely ROP 774,667 kg, ROP 1394 kg, ROP 968,317 kg. Of the three, the right waste sales proposal is ROP 774,667 with a sales period of 20 days / 12 times a year, and the ROP is still below the capacity limit of the waste bin.
