Tue, 31 Dec 2024 00:00:00 +0000

This research aims to improve the service quality at Selakosa Coffee using Service Quality (Servqual) and Importance Performance Analysis (IPA) methods. As competition in the coffee shop industry increases, providing excellent service has become crucial to attract and retain customers. The study surveyed 90 respondents and analyzed five key dimensions of service quality: tangibility, reliability, responsiveness, assurance, and empathy. The results revealed significant gaps between customer expectations and actual service in three key areas: indoor space size, toilet availability, and cleanliness. These factors were categorized as high-priority issues based on the IPA Cartesian diagram, indicating that immediate improvements are needed. The root causes of these service shortcomings were analyzed using the fishbone diagram, and improvement recommendations were formulated using the 5W + 1H method. The study concludes that by addressing these gaps, Selakosa Coffee can enhance customer satisfaction, reduce complaints, and strengthen its market position. Future studies could explore additional service variables and include a larger sample size for more comprehensive results

Ordering raw materials optimally can provide benefits for the company. PT. XYZ places an order for sand 12 (twelve) times in 1 (one) period which causes it to be ineffective and inefficient. Therefore, it is necessary to have a method that is able to control the total cost of raw material inventory in order to ensure a smooth production process. The EOQ (Economic Order Quantity) method is used to identify orders to minimize the total cost of holding inventory, purchase raw materials with each purchase with a minimum cost, and orders that minimize total inventory costs. Thus the EOQ (Economic Order Quantity) method can save the cost of raw material inventory which is able to make a company profitable by applying this method. The results of this study indicate that the EOQ (Economic Order Quantity) method can save raw material inventory costs compared to traditional methods (policy firms). The savings in the cost of raw materials for sand in the EOQ (Economic Order Quantity) method were Rp.8.394.400.

This research purpose to calculate the optimal quantity of raw material orders for chicken animal feed and the number of ordering frequencies, calculate the total cost of raw material inventory for chicken animal feed, analyze the most efficient method that must be applied to minimize the cost of raw material inventory at PT Kerta Mulya Saripakan. The method used in this research is the Economic Order Quantity (EOQ) and Just In Time (JIT) methods. After done analysis, the cost of raw material supplies incurred by the company, calculated according to company policy, reached IDR 459,616,202. By using the Economic Order Quantity (EOQ) method, the total inventory cost is IDR 340,449,297. Meanwhile, using the Just In Time (JIT) method, the total inventory costs incurred were IDR. 218,939,956. So a method that can minimize inventory costs at PT. Kerta Mulya Saripakan uses the Just In Time (JIT) method.

OPTIMALISASI PENGENDALIAN KUALITAS PRODUK PALET KAYU MELALUI PENDEKATAN RCA & SPC

This study aims to optimize the quality control of wood pallet products at PT. Azdhi Kayu Kreasi by using the Root Cause Analysis (RCA) and Statistical Process Control (SPC) approaches. The problem faced by the company is the high level of product defects that can reduce customer satisfaction and increase production costs. The RCA method is used to identify the root cause of product defects, while SPC is used to monitor and control the production process. Data were collected through field observations, interviews, questionnaires, and internal company documentation. The data were analyzed using P charts, Pareto diagrams, and fishbone diagrams. The results showed that the main cause of product defects was wood cracking, which was caused by factors such as poor raw material quality, production process errors, and unsuitable environmental conditions. The implementation of RCA and SPC proved effective in identifying and reducing the causes of product defects. By making improvements to the production process and selecting better raw materials, the product defect rate can be significantly reduced. This research makes a practical contribution to the company in improving product quality and production process efficiency.

ANALISIS PENGENDALIAN PERSEDIAAN BAHAN BAKU MENGGUNAKAN METODE ECONOMIC ORDER QUANTITY (EOQ)

This study analyzes the raw material inventory control of wood at PT Suryamas Lestariprima using the Economic Order Quantity (EOQ) method to achieve inventory cost efficiency. The results show that the EOQ calculation produces an optimal order quantity of 19.8772 m³ for durian wood, 18.8571 m³ for rambung wood, and 14.0553 m³ for miscellaneous wood, designed to minimize the company’s inventory costs. Additionally, the determination of safety stock at 14.954,5081 m³ for durian wood, 17.101,8334 m³ for rambung wood, and 384,7911 m³ for miscellaneous wood helps the company handle potential demand fluctuations during the lead time. This study also establishes the reorder point as the minimum threshold before reordering, namely 15.038,4718 m³ for durian wood, 17.230,6429 m³ for rambung wood, and 404.1126 m³ for miscellaneous wood. The application of the EOQ method results in inventory cost savings of IDR 5,409,005,289 for durian wood, IDR 2,888,543,167 for rambung wood, and IDR 1,506,367,701 for miscellaneous wood. Based on these findings, it is recommended that the company consider implementing EOQ as a standard in managing inventory to maintain operational efficiency.

Mon, 23 Dec 2024 00:00:00 +0000

PT Cahyo Permata Abadi is a company that provides precision measurement solutions and high-quality services for various industries by ensuring accuracy and efficiency in every project, so it is important to pay attention to the K3 aspect in the maintenance activities carried out, one of which is in the field of weighbridge maintenance services. This study aims to analyze the Occupational Safety and Health (K3) risks at PT. Cahyo Permata Abadi in weighbridge maintenance activities. The research method is Job Safety Analysis (JSA). The results of the Risk Analysis study show that several activities have significant potential hazards. In troubleshooting, there is a risk of electric shock and muscle injury with a risk value of 9. Checking the electrical system faces the risk of electric shock and short circuits with a risk value of 8. Other activities such as sensor calibration, platform cleaning, and load testing have moderate risks with potential hazards such as falling from a height, slipping, and being hit by a load. Research suggestions for risk control should be carried out through various safety measures, including the use of Personal Protective Equipment (PPE) such as insulating gloves, safety shoes, and full body harnesses. In addition, safety procedures such as Lock Out Tag Out (LOTO), warning signs, and safe work procedures are also implemented. These controls are designed to minimize potential hazards and ensure worker safety while carrying out these activities.
