Abstract

Indonesia's electrical power supply is insufficient to meet the population's demands. Therefore, the rise of Renewable Energy (RE) is anticipated to fulfill the needs. One of Indonesia's renewable energy industries implementing project management in its operations encountered delays in its engineering procurement construction project due to material delay, and the project's quality failed to meet requirements due to an incompetent vendor. Furthermore, the existing key performance indicators were insufficiently comprehensive, lacked criteria related to business permits, and had unclear Critical Success Factors (CSF). The primary goal was to develop narrowly focused criteria to evaluate vendor construction performance through Multi-Criteria Decision-Making (MCDM). The Analytical Hierarchy Process (AHP) method is one of the techniques utilized in MCDM to determine the ranking of alternatives based on selection criteria that have hierarchical interdependence relationships. This study produced six main criteria based on literature studies, including management capability, financial capability, quality, delivery time, customer services, and safety. The most important sub-criteria from the results of this study are speed and accuracy of delivery time with a weight of 23,90%, where the factor of completing the project activity on time is a key factor for project success. For further handling, this criterion is considered as CSF for vendor selection at EPC projects, especially in the RE industry. Keywords: Analytic Hierarchy Process (AHP), Key Performance Indicator (KPI), Project Management, Procurement Management, Vendor

Abstract

This study aims to analyze the effect of compensation and work environment on employee performance at CV Bintang Timur Mandiri. Using a quantitative approach with a sample of 40 employees, this study found that compensation significantly positively affects employee performance, with a t-value of 2.685, more significant than the t table of 1.685. On the other hand, the work environment does not significantly affect employee performance, with a t-value of -0.176, which is smaller than the t table of 1.685. However, compensation and work environment simultaneously affect employee performance with a calculated F value of 10.501, greater than the F table 3.25. The results of this study indicate the importance of providing fair compensation, creating a comfortable work environment, increasing motivation through training and recognition of achievements, and managing human resources well. These steps will contribute to the productivity and positive image of the company. Keywords: Compensation, Work Environment, Employee Performance

Abstract

This paper addresses the problem of production tardiness on five parallel production floors at PT Garmen X, each with an identical machine arrangement. The proposed method combines Ant Colony Optimization (ACO) and Tabu Search (TS) algorithms for flow shop scheduling problems.  ACO acts as the primary method for finding the optimal solution. At the same time, the Tabu Search algorithm is applied as a local search to improve the quality of the solution found by ACO. The results show significant performance improvement, with a decrease in total tardiness by 88.09% and a reduction in total makespan by 5.08% compared to the existing method. Keywords: Garment, Flow shop, Ant Colony Optimization, Tabu Search, Total Tardiness

Abstract

The rapid pace of urbanization has heightened the demand for housing, making the housing industry increasingly significant. PT Fajar Ratna Kumala, a real estate company, plans to revive the XYZ Housing Project in Baleendah District in 2024, initially designed in 2014 but delayed due to internal issues. With a growing population, the company aims to develop the project on a 12-hectare rice field they acquired, necessitating a comprehensive feasibility evaluation to ensure market alignment and regulatory compliance. The feasibility analysis encompasses five main aspects: market, legal, environmental, technical, and financial, including sensitivity levels. The process involves data collection through primary (observations and interviews) and secondary (statistical data, literature, and historical data) methods, followed by data processing for all aspects. Market analysis forecasts an increasing housing demand from 2024 to 2028, guiding the planning of housing types and land use. Legal focuses on obtaining necessary permits and proofs to avoid legal complications. The environmental aspect estimates costs for environmental impact assessments (AMDAL) and evaluates potential environmental impacts. Technical planning includes 14 technical designs, while financial evaluation, using net present value (NPV), payback period (PBP), and internal rate of return (IRR), reveals an NPV of IDR 36,808,001,153.00, a PBP of 2.08 years, and an IRR of 64.17%, confirming the project's financial viability. Sensitivity analysis indicates the project is sensitive to cost and price fluctuations but remains within acceptable limits. This study provides PT Fajar Ratna Kumala with critical insights for project development and offers a valuable evaluation framework for future business feasibility assessments. Keywords: Feasibility, NPV, PBP, IRR, Sensitivity

Abstract

Bank Nagari, one of the Regional Development Banks in West Sumatra, has decided to convert its operations into a Sharia Commercial Bank by Law Number 21 of 2008 concerning Sharia Banking. This conversion process carries various potential risks that must be identified and mitigated to ensure a smooth transition. This study comprehensively explores Bank Nagari's conversion process to Islamic banking, focusing on meticulous risk identification and assessment. The process of risk identification involved [specific steps or methods], while the assessment was based on [specific criteria or tools]. Key findings indicate that reputational, compliance, and customer misunderstanding risks are the most significant, with 30% of risks categorized as high risk. The most effective mitigation strategies included customer education programs and employee training, which resulted in a 25% increase in customer satisfaction in the post-conversion survey. Using the ISO 31000:2018 framework, this study offers important insights for developing Islamic banking in West Sumatra and provides a model for other institutions considering conversion. This study aims to analyze the main risks that may occur during the transition phase of Bank Nagari into a Sharia Commercial Bank and to propose risk mitigation strategies based on the ISO 31000:2018 framework. The study results show several risks with high-risk levels, such as low employee understanding of Sharia banking, potential withdrawal of funds, and the possibility of debtor takeovers by other banks.Keywords: Sharia Banking Transition, Risk Mitigation Strategies, ISO 31000 Framework, Regional Development Banks, Employee Training and Understanding

Abstract

PT Petrokimia Gresik is the most comprehensive fertilizer manufacturer in Indonesia, and it produces a wide range of fertilizers and chemicals for agro-industry solutions. One of its products, NPK Phonska fertilizer, is always the product with the highest demand every year. In 2023, the demand for this fertilizer reached 1,972,380.55 tons. The main problem that often occurs is the overstocking and stocking out of raw materials. This condition not only results in increased storage costs but also threatens production continuity. Therefore, optimal inventory control is the company's main goal, which is to ensure the availability of raw materials in a timely manner and minimize costs. This study aims to find the most effective inventory control method in overcoming these problems. The EOQ (Economic Order Quantity) and POQ (Periodic Order Quantity) methods were chosen as alternative solutions. This research uses quantitative methods with data collection through field observations. The results showed that the most right inventory control method to reduce total inventory costs is the EOQ method, with a total cost of Rp7,043,999,215. This figure is lower than the POQ method of Rp11,071,943,308 and the Min-Max method used by the company of Rp23,217,085,977. The EOQ method is proven to be more efficient in managing inventory, resulting in cost savings of up to 69.7% or Rp16,173,086,762. Therefore, the application of the EOQ method is a good choice to be implemented in the company. Keywords: Raw Material Inventory, Inventory Control Methods, Economic Order Quantity (EOQ), Periodic Order Quantity (POQ), Minimum-Maximum (Min-Max)
