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

In today's rapidly evolving industrial landscape, businesses are increasingly challenged to strike a balance between enhancing productivity and maintaining product quality. Company X, a renowned cement manufacturer in Indonesia, relies heavily on four key raw materials, among which clay is particularly crucial for the raw mix. Recent trends have shown a decrease in the Al2O3 composition of clay, necessitating adjustments in clay capacity to uphold quality standards. A thorough technical evaluation of the plant highlighted that a significant number of critical machines, totaling 17, were operating with mechanical availability below the desired threshold. Additionally, a utility analysis pinpointed a shortfall in meeting the required clay tonnage, leading to the identification of machines that would benefit from retrofitting. The financial implications of this initiative were substantial, with the initial investment for the upgrades and subsequent operational costs in the first year being considerable. Yet, this expenditure was offset by a notable profit in the first year post-retrofitting. Key financial metrics further underscored the project's viability: a highly favorable Net Present Value (NPV), an impressive Internal Rate of Return (IRR), a rapid Payback Period (PP), and a significant Profitability Index (PI). These parameters, derived from an exhaustive analysis, clearly support the strategic decision to invest in retrofitting the production machinery at Company X's cement plant, illustrating the project's feasibility and the prospective benefits of this investment.

Abstract

This paper presents a case study of determining vehicles’ routes. The case is taken from a pharmaceutical products distribution problem faced by a distribution company located in the city of Padang, Indonesia. The objective of this paper is to reduce the total distribution time required by the salesmen of the company. Since the company uses more than one salesman, then the problem is modeled as a multi travelling salesman problem (m-TSP). The problem is solved by employing genetic algorithm (GA) and a Matlab® based computer program is developed to run the algorithm. It is found that, by employing two salesmen only, the routes produced by GA results in a 30% savings in total distribution time compared to the current routes used by the company (currently the company employs three salesmen). This paper determines distances based on the latitude and longitude of the locations visited by the salesmen. Therefore, the distances calculated in this paper are approximations. It is suggested that actual distances are used for future research.

Abstract

Electrical energy requirements in Indonesia annually increase in line with economic growth and an increase in population. So, PT PLN (Persero) have to be able to fulfill the public demands for electrical energy. One of the power generation existed is Steam PowerGeneration. The condition of power generation depended on the maintenance, so, well maintenance made power plant operated at ease condition. Production process in SteamPower Generation of Ombilin used a closed cycle or continuous process. If a machine or an equipment damaged, it will stop the whole function. In the production process, the company involved several main engines are boiler, turbine, condenser, and generator. But the damage often occurs in turbine engine which caused the generation power in Steam PowerGeneration of Ombilin can not operate. Therefore, it needs a maintenance action of machinery/equipment to be able to prevent the damage. The right strategy to keep the engine operating is determining the optimal maintenance interval of equipment for minimizing downtime.The stages of this research begin by determining the critical engine with Criticality Analysis method. Then, the determination of the critical components using Pareto diagram. Then, the determination of the probability density function (pdf) and the reliability of critical components. After that, the determination of maintenance intervals of the critical components by using the criterion of minimizing the downtime that will be used to make maintenance scheduling.Based on the processing data has been done, it was found that the critical engine is a turbine engine with a total value is 44 and the critical components of a turbine engine are membrane turbine, bearing and turning gear with the examination time interval for each critical component are 960.48 hours (40 days), 908.57 hours (37 days) and 1150.28 hours (48days). While the preventive replacement intervals for components of turbine membrane is after operating for 3410 hours, the replacement for bearing components can be carried out during overhaul after operating for 8000 hours and the replacement intervals for components of turning gear is after operating for 4500 hours. The reliability values for each critical component before and after preventive maintenance remains the same, but the value of downtime on each component decreases. The total values of availability for each critical component exceeds 95%.

Abstract

Nowadays, automation system become an important aspect of the manufacturing process because could make integration manufacturing process on it more effective and more efficient. PLC or Programmable Logic Controller is one kind of automation system. Many industries use PLC as automation control device in the manufacturing process to control all kind of process. For example at transportation process of coals in generator industry. Coals could be burned because main elements of coals are carbon, hydrogen, and oxygen. Base on this prototype early warning system design, we get the result if sensor thermocouple detects temperature larger than setpoint temperature (it is 2000C), then PLC will give an order to shut down the output, that is a belt conveyor. The result of this prototype design could use at coals transportation as an early warning system. The design of prototype early warning system could detect and prevent fire because of the consequence of burned coals until spreading of fire could be avoided.

Abstract

Hydropower is one of the power plants that supplies electrical energy. It has several machines and equipment that have a time limit of use. To anticipate the limitation of the use, maintenance of machinery and equipment are needed in order to return its original state and can perform its function as usual. Therefore some indicators required to determine maintenance work performance level to provide the optimal results. The Traditional measurement methods have some limitations that make it difficult to implement in industrial environments. This requires a performance measurement method that can provide a balanced perspective on the overall system performance. One of them is implementing the Maintenance Scorecard and Objective Matrix (OMAX) method to assess the performance of hydropower maintenance. Objective research in this assessment is to integrate Maintenance Scorecard and Objective Matrix (OMAX) approach in Maninjau Hydropower. Key Performance Indicators (KPI) are defined by 6 perspectives: productivity perspective, cost effectiveness perspective, a safety perspective, an environmental perspective, quality perspective and learning perspective. The priorities are determined by using Analytical Hierarchy Process (AHP). We then measure the performance of maintenance by using Objective Matrix (OMAX) until we get the level of achievement of the performance in the current situation.The results obtained in the process of designing the scorecard maintenance on the Maninjau hydropower that produces overall 20 KPI consists of 9 KPI for productivity perspective, 4 KPI for quality perspective, 2 KPI for safety perspective, 2 KPI for environmental perspective and 3 KPIs for learning perspective. There are 5 KPIs for corporate level, 8 KPIs for strategic level and 7 KPIs functional level. The operation results show the number of KWH that produced, Capacity Factor and Equivalent Outage Force Factor are in the yellow zone. It means the attentions and improvements are needed to improve performance in the next period.
