Abstract

XYZ Store is a company engaged in the textile industry, whose main activity is the production of printed fabrics. The raw materials used in the textile production process are fabrics and in the implementation of the production process these raw materials are always available for the smooth running of the production process. Therefore it is necessary to carry out planning and control of raw materials that are more efficient, then an analysis is carried out using the EOQ method as an option as a comparison between policies that have been implemented so that companies can choose which policy is more efficient in terms of spending on inventory costs or total inventory costs. After doing the calculations, it can be seen that the costs incurred by the company amounted to IDR 7,876,464.1. Meanwhile, the total inventory cost incurred by the company when using the EOQ method is IDR 3,564,927.2. it can be seen that the savings are Rp. 4,311,536.9 when using the EOQ method. While the obstacle in this research is that the EOQ method that has been disclosed by the author in this study cannot be implemented at the XYZ Store due to the agreement factor from the supplier who sends materials once a month. Even though the storage facilities owned by Store XYZ are very adequate, so that the minimum inventory limit that must be stored according to the EOQ calculation can be carried out in field conditions

Abstract

Natural content that supports the need for raw materials and materials needed is provided by the nature around us, such as various plants, soil, water, natural stones, and others. Most of them can be further processed into raw materials for construction products, such as roof tiles and other infrastructure facilities. The financial feasibility aspect is important considering that the business can be categorized as a project, which requires a long payback period based on the accounting period. During this time period there are various things that are full of uncertainty which are influenced by the rate of inflation and bank interest rates, so that the value of investments issued and the income or money obtained now will be different from the value of money in the future, which is called with the value of time rather than money. It is hoped that the analytical tool will be able to provide consideration, input and anticipation for the future of the roof tile manufacturing unit project by paying attention to capital budgeting, which can then be analyzed from a financial aspect through payback period (PP), net present value (NPV), profitability index ( PI) and internal rate of return (IRR). In the roof tile manufacturing business, the PBP is 1 year, 8 months, 6 days faster than the maximum period of 8 years of the project value, positive NPV of IDR 536,821,468, PI of 2,841 greater than number 1 and IRR of 14,835 greater than the cost value of capital 12%. As a basis for decision making through a capital budgeting approach through financial analysis.

Abstract

Yogyakarta is a city that is often called a miniature of Indonesia, has a multitude of features. Starting from governance to many other features. Trans Jogja is one of the BRT products for the city of Jogja which is said to have been initially built to provide clean, neat and comfortable city transportation for everyone. However, Trans Jogja, which is heralded as an improvement in public transportation service modes, is in reality still less than optimal. In order to meet the expectations of prospective passengers at bus stops, service improvements and innovations are needed. In this research, Trans Jogja bus stops will be identified using the SERVQUAL and House of Quality methods. The cause of customer dissatisfaction in the Servqual analysis is that from the results of data processing it was found that there was a gap in all service dimensions at the Trans Jogja bus stop. Determining the highest to smallest improvement priorities to increase customer satisfaction in the House of Quality analysis is conducting training to improve performance, evaluating staff performance, updating schedules and daily departure routes clearly and in detail, controlling the availability of service facilities, implementing SOPs for staff , Providing a box for suggestions and criticism, and Providing supporting facilities for the safety and smooth running of Trans Jogja bus stop users.

Abstract

BPR or business process reengineering is a process to achieve radical improvements in terms of time, quality, rewards, and of course costs by simultaneously redesigning processes, organizations, and information systems. In this study, IT/technology and HR factors (human resources) are used in re-engineering public facilities assisted by expert systems to create efficiency and effectiveness and increase value. The main factor used in this study is the management system, especially for making changes to the organizational structure, improving the administration system, and Relationship Management. The model suitability test in this report uses several criteria, including Chi-Square, GFI, AGFI, and RMSEA. Although the final model obtained a high Chi-square value (13.157) with a probability of zero, because several other criteria were met with an AGFI value above 0.9 and an RMSEA value below 0.08, the model is considered suitable. Based on the model output, it is known that not all antecedent variables have a significant influence on the consequent variables. Likewise, not all hypotheses are accepted. All antecedent variables cannot explain the consequent variables because the R2 value is less than 0.5.

Abstract

CCTV monitoring activities are static tasks that require continuous visual focus and prolonged sitting, making operators prone to physical fatigue, visual impairment, and decreased performance. Common problems include non-ergonomic work postures, thermal discomfort, and lighting glare on monitors. This study aims to evaluate CCTV operator performance through a comprehensive ergonomic approach that includes posture analysis, work activity patterns, and environmental conditions. The methods used include work sampling to measure the proportion of productive and idle time, posture analysis using REBA to determine musculoskeletal risk, and measurement of environmental parameters such as temperature, air velocity, viewing distance, and lighting quality. The results showed a REBA score of 3 (low risk but improvement needed), operator focus time of only 8–10 minutes, normal idle time of 15 minutes, and an allowance of 17 minutes. Nighttime thermal conditions were below comfort standards, and glare was found to interfere with visibility. These findings confirm the need to redesign workstations and improve working conditions to improve CCTV operator performance.
