Abstract

PT. PLN (Persero) is the sole manager of the electricity industry in Indonesia which is owned by the Indonesian government in the form of a State-Owned Enterprise. Steam power plant is one of the leading power plants in Indonesia. Aceh Province has one steam power plant located in Nagan Raya Regency and has two generating units with an installed capacity of 2x110 Megawatts. However, a power outage is unavoidable and still often occurs if one of the plants is damaged or damaged. Corrective maintenance activities and overall maintenance is one of the causes of the high frequency of interference or damage, especially in the boiler section. This study aims to determine the proposed maintenance and repair time to achieve a reliability level of up to 80% in every important boiler component. The proposed maintenance and repair time can be obtained based on historical time to failure and time to repair data. Good maintenance and repair time can be assessed based on high reliability values. The results obtained that the proposed maintenance time is 67 hours to 585 hours to achieve 80% reliability value on eight important components in the boiler section. While the proposed repair time is from 1,036 hours to 1,497 hours to reach 80% reliability value on eight important components in the boiler section.

Abstract

The community's conventional salt production business is one of the economic drivers of the community. In addition to being able to provide a lot of jobs for people in Indonesia's coastal areas, the people's salt production business is also seen as a way to reduce poverty. Pidie Regency, which is included in the Province of Aceh, is one area that has a wide coastline and can be utilized as a salt farmer business. Pidie is an area that has a salt production business with a total production of 449.05 tons/month. The problem faced in the traditional salt processing business in Pidie District is the unknown level of risk that exists in each salt production process. The purpose of this study is to determine the level of risk in the traditional salt production process using failure mode and effect analysis (FMEA) and probability impact matrix (PIM) in the Saho Adab people's salt business group in Keude Ie Leubeu Village, Kembang Tanjong District, Pidie District. FMEA is a form of qualitative analysis that assesses the severity , occurrence and detection on each activity and then given a value on a predetermined scale. Whereas risk assessment using PIM only assesses the severity and occurrence. Based on the analysis of failure and effect modes, the salt production process has a high level of risk, namely the packaging process with an RPN value (risk priority number) 75, the salt water storage process with an RPN value of 48, the drying process with an RPN value of 45 and the level of the soil process with an RPN 45. While the results of the matrix impact probability obtained by the salt production process that has a high level of risk, namely the process of storing salt with a value of 5, the packaging process with a value of 4, the process of leveling sand with a value of 3,5 and the process of salt water filtration with sand filtration media containing NaCl with a value of 3,5.
