Abstract

Manufacturing companya PT.Sinar Jatimulia Gemilang produces many types of plastic packaging, one of which is mini oreo cups.The production system in this company is based on job shop, changing product demand and limited product capacity make it difficult for the company to make a productin plan. The purpose of this research is to make a mini cup production plan to meet future demand with the aim of minimize production costs. At the initial stage a field study was conducted to obtain to required data. The data obtained through interviews with production employees from the company. Then do the literature study through books and articles from related journal as the theoretical basis used in this research. Production planning research using exponential smoothing forecasting method with α=0.6 and standard error of 617814.3 was selected with the criteria of the smallest mean square error and aggregate planning.The result of analysis I strategy of inventory level inventory cost is IDR. 441,654,900. In analysis II the strategy for variation in the number workers costs is IDR. 747,373,500. The cost for analysis III subcontracting strategy is IDR. 79,065,843,000. From the research that production cost before the calculation is IDR. 52,002,000,000 and the number of workers is 4. After the result of the research on optimization the number of workers that will be used by 2.

Abstract

This study aims to examine and mitigate operational risks in the procurement of goods and services at the Ministry of Industry. The research was carried out at the Procurement Unit of the Ministry of Industry in Jakarta, with data collected through interviews, observations. The applied method is the House of Risk (HOR), which consists of two stages: HOR 1 to identify risks and determine priority risk agents based on the Aggregate Risk Priority (ARP) value, and HOR 2 to formulate mitigation strategies by considering the effectiveness-to-difficulty ratio (ETD). The findings reveal 20 categories of goods and 17 categories of services with a total procurement value of IDR 2.37 billion, while estimated losses due to operational risks amounted to IDR 48 million, or approximately 2% of the total value. The implementation of the HOR method successfully reduced the number of risk incidents from 23 to 10 cases and decreased the loss value by IDR 216.4 million, equivalent to 56.5%. Thus, it can be concluded that the House of Risk method is effective in supporting the development of more reliable, efficient, and low-risk procurement strategies, while also enhancing operational risk management within the Ministry of Industry.
