Abstract

Indonesia electrical energy consumption growth that reached 9.2% per year requires every plant to always pursue consistent and sustainable improvement to be able to cope with the growth. Maninjau Hydropower is one of the assets of strategic energy resources to meet the electrical energy supply, especially for the southern Sumatera region. Risk management in Maninjau hydropower take place without any standard of measurement standards, so management and risk management actors do not have an overview and guide to improve the performance of the risk management activities. In this study, a standard measure used is to measure the level of maturity of the risk management implementation using the framework of the Risk and Insurance Management Society (RIMS) for Enterprise Risk Management (ERM). Measurements carried out for the realization of the value and the expected value of risk management implementation in Maninjau hydropower, as well as designing the evaluation chart implementation of risk management by integrating Key Risk Indicators (KRI) from the expected value. Based on the results of the measurements made, it was found that the actual implementation of risk management in Maninjau hydropower located on the third level (repeatable), while the implementation of the expectation value is found to be at the highest level (leadership), and the percentage achieving overall expectation value has reached 62%. The draft also raises the risk evaluation chart 15 Key Risk Indicators to be achieved by Maninjau hydropower to achieve the expected value at the leadership level.Keywords: Risk Management, RIMS for ERM, KRI

Abstract

PT Abaisiat Raya is one of the manufacturers of rubber crumb (crumb rubber) in the city of Padang. Latex inventory management system at PT Abaisiat Kingdom basically signinfikan still need improvement. It is based on the planning activities in the warehouse inventory of raw materials firms irregular, thus causing excess stock (over stock) at a time and shortage of stock (stock out) at other times. Process optimization is done with latex inventory system involving factors such as demand forecasting production planning or latex needs during the period of next 12 (in 2012), the costs involved, the waiting time (lead time), the implementation of forecasting methods, determination of size lots (lot sizing), the determination of safety stock (safety stock), and re-ordering time (reorder point), so the output will get a number of requests are for 12 periods ahead, the size of each reservation period, the total cost is required, when re-ordering will be done , as well as how much inventory to latex in the warehouse. Based on these results, it was found that the optimal size of the book is the same as the demand for each period (reservation is made each period) due to a cyclical pattern of demand and decreases throughout the planning period. Value of the stock or safety stock is located in Kg 114,282.20, and re-ordering time (reorder point) to cope with fluctuations do when the stock has reached a level of 333,130.95 kg.Keywords: Forecasting, Time Wait, Lot Size, Safety Supplies, Reorder
