KAJIAN PENGEMBANGAN INDUSTRI PENGOLAHAN PASIR BESI DI KABUPATEN TRENGGALEK DENGAN PEMANFAATAN BENDUNGAN BAGONG DAN TUGU SEBAGAI PEMBANGKIT LISTRIK TENAGA MIKROHIDRO (PLTMH) GUNA MENDUKUNG PEMBANGUNAN YANG BERKELANJUTAN

Abstract

This research is aimed to provide a study about the development of iron sand industry in Trenggalek by employing Bagong and Tugu dams as Micro Hydro Power (MHP) plant in term of achieving the Sustainable Development Goals (SDGs). This research is conducting through literature studies to resume the information and data about iron sand resources in Trenggalek, including the suitable technology of iron sand processing. It also points out the potential of Bagong and Tugu dams as MHP plant to provide renewable and cleaner energy. This study proposes a concept of iron sand processing through a pyrometallurgical route by using Sintering - Blast Furnace technology. This Sintering – Blast Furnace technology processes iron sand through a carbothermic reaction to produce ferrous metal. This research uses a simulating method by utilizing the Factsage software to predict the conditions of carbothermic reactions during the process. This simulation provides an analysis to determine the appliances requirements and the consumption of electrical energy required in iron sand processing through Sintering - Blast Furnace technology. Based on the research, the result shows that iron sand in Trenggalek can be processed through Sintering - Blast Furnace technology to produce ferrous metal by recovering 86,98% of the iron with the supply of electrical energy from Bagong and Tugu dams to run the processing appliances in iron sand industry.
