Abstract

Raw material inventory is a crucial aspect of a business, as it can significantly affect the costs incurred. One type of raw material is perishable raw material, which, due to its nature, relates to shelf life and can impact not only the quantity of inventory but also inventory costs. One business that utilizes perishable raw materials is the small and medium-sized enterprise (SME) producing serundeng, using sweet potatoes and ghost peppers as perishable raw materials. The use of easily spoilable raw materials can be detrimental to SMEs if not managed properly. To avoid losses and improve efficiency, an analysis will be conducted by calculating inventory control. This research employs the multi-item Economic Order Quantity (EOQ) method, considering expiration dates and quantity discounts. The final outcome of the research includes a comparison of inventory levels between conventional methods and the proposed method, along with an analysis of the management implications of the findings. The results indicate that the total inventory costs without utilizing inventory control methods are higher than those using inventory management techniques. Therefore, this study provides insights to SMEs that effective inventory control can help the company not only reduce expenses but also increase revenue.

Abstract

West Sumatra Province has been designated by the Minister of Maritime Affairs and Fisheries as a Minapolitan area with seven regions in West Sumatra. Since the establishment of West Sumatra as a Minapolitan area, there has been no research examining the evaluation of suitability between planning and implementation of the Minapolitan fishing area development program in West Sumatra. The aim of this research is to determine a strategy for developing the Minapolitan area in West Sumatra which can improve the welfare of fishermen in the area. The data collection technique in this research is the primary data collection method in the form of field observations, interviews, FGDs and filling out questionnaires by respondents selected based on their knowledge of the Minapolitan area development program, such as representatives of the DKP, Port Service, business actors, and fishermen figures. The method used to determine strategic priorities for developing the Minapolitan area is using the Analytical Hierarchy Process approach. Based on the AHP calculation, the CR value <= 0.1 shows that respondents are consistent in making assessments and the resulting solutions are optimal. Likewise, for the CR value in the calculation for the assessment of each indicator, the CR value obtained is 0.0263 for the assessment of the supporting facility factor indicator, 0.0231 for the assessment of the supporting infrastructure factor indicator and 0.0061 for the assessment of the regional program factor indicator.The strategy obtained for developing the Minapolitan area is seen from the priority value between the highest factors, namely the supporting facilities and supporting infrastructure factors. The priority indicators that need to be immediately improved are the indicators for the availability of fishing ports, followed by the availability of fishing gear and the availability of clean water networks, the results obtained from the priority order of all the indicators assessed.

Abstract

KRM ice cream shop is a popular destination in Sanur, Bali. The intensity of customer visits on regular days is already quite crowded, even more so during the holiday season. Due to the location of Gerai KRM which is adjacent to the road sidewalk, it often causes congestion in the area. The long and less conducive queuing system is the main reason customers discourage coming. This research was conducted during peak hour, namely 11:00 to 13:00 which is lunch time. These data are then tested using the Stat::Fit feature to determine the type of data distribution. This type of data distribution will later be used to determine the length of the system process when tested in ProModel software, more precisely it will be included in the processing sequences section. The research results show that there is an entity of customers in waiting of 6.13% and blocked by 10.10% which is caused by a lack of capacity and service units in the system. Based on the problem, the proposed improvements given by the author are the addition of cashier units and also the queue capacity at the Ice Cream storefront service. The output of the proposed system simulation is a decrease in the percentage of blocked 1.32%. Then the percentage of full in the queue row which became 0% and the percentage of full in the ice cream storefront was reduced to 1.71%.

Abstract

PT. UMSurya Bina Bangsa is a company engaged in the production of Bottled Drinking Water (AMDK). The products produced by PT. UMSurya Bina Bangsa include Suli 5 in 120 ml and 240 ml sizes, as well as S-Five in 330 ml and 600 ml sizes. The issues faced by PT. UMSurya Bina Bangsa include Defects such as dented bottles and broken caps. The aim of this study is to improve the quality of bottled water products. The author of this study uses the integration of Six Sigma and Failure Mode and Effect Analysis (FMEA) methods to improve product quality. Based on the research results, the Root Cause Analysis (RCA) indicates that the majority of product Defects are caused by operator inaccuracy and the use of low-quality materials. Failure Mode and Effect Analysis (FMEA) results show that the highest RPN is caused by the bottle cap pressing process. From the Measure phase, sigma level calculations show a sigma value of 2.10 with a DPMO of 36,041. Improvement recommendations include creating racks for bottle caps to reduce Defects in broken caps, and adding dividers for bottles to prevent crushing while on the conveyor. From the estimated calculations, after implementing the improvement recommendations, the sigma level is expected to increase from 2.10 to 2.54.

Abstract

Rebon shrimp is the catch of fishermen around Sukolilo Baru area, Bulak District of Surabaya. Rebon shrimp processing is only sorted and then dried and sold to collectors. However, the drying process has no definite parameters of factors that can affect the quality of dried rebon shrimp. In overcoming this, research was conducted on improving the quality of dried rebon shrimp. The increase certainly raised several quality responses, namely the color and moisture content of rebon shrimp. The resulting multiresponse needed to be converted into a single response. To optimize multiresponse into a single response, the Taguchi method was used in combination with the Gray Relational Analysis (GRA) and Principal Component Analysis (PCA) methods. Factors and levels were the volume of rebon shrimp (A) with levels of 4 Kg, 4.5 Kg, and 5 Kg, drying time (B) with levels of 90 minutes, 120 minutes, and 150 minutes, and drying temperatures (C) with levels of 41- 44ºC, 45-49 ºC, and 36-40 ºC. The quality characteristics were nominal that was the best (if the resulting value is close to the target value, the quality is better). The result produced PCA weighting values on PC1 as evidenced by eigen>1 values. The optimal combination is the volume factor of rebon shrimp at the level of 4.5 Kg, the drying time factor of 120 minutes, and the drying temperature factor of 45 – 49 ºC.

Abstract

Service quality is crucial for companies in the service sector, directly impacting customer satisfaction. PT BLI, a company offering TPS warehouse rental services, is facing issues with a low influx of containers and customer complaints. This research aims to analyze the service quality at PT BLI's warehouse storage section using the Servqual method, which encompasses five quality dimensions and 24 attributes, followed by Importance Performance Analysis (IPA) to identify attributes that require immediate improvement. The Servqual analysis revealed that 10 attributes of PT BLI's service quality do not meet customer expectations. Through IPA, five attributes were identified as high-priority for improvement: the safety of goods in the warehouse (gap of -0.07), the informativeness of employee service regarding activity updates (gap of -0.14), the speed of employees in processing goods in and out of the LCL warehouse (gap of -0.34), the ability of employees to understand consumer needs (gap of -0.01), and the communication skills of employees in providing excellent service (gap of 0.32). Addressing these critical service quality gaps will help PT BLI enhance customer satisfaction, reduce complaints, and potentially increase the number of incoming containers, positively impacting the company's standing in the warehouse rental industry.
