Abstract

The clean water distribution system in Pamekasan faces obstacles in the form of distribution imbalance, suboptimal infrastructure, and pipe leaks, especially in the Sumber Nyamplong area, which is one of the main sources. These problems have an impact on customer dissatisfaction and a decrease in the quality of life of the community. This case study aims to provide strategic solutions to improve the effectiveness of clean water distribution in the area. The activity partner is PDAM Tirta Jaya, a BUMD responsible for providing clean water in the Pamekasan area. A quantitative approach was used with a survey of 95 customers. Data analysis used regression analysis to understand the influence of quantity, quality, and continuity factors on customer satisfaction. The results of the study showed that water quality provided the highest level of satisfaction (65.26%), while continuity and quantity were at 42.11% and 40%, respectively. The proposed solutions include remapping the distribution network, improving the infrastructure system to reduce leaks, and providing reserve tanks for areas with high demand, to support the sustainability of PDAM services in the future.

Abstract

Effective storage system management is a crucial aspect in supporting smooth operational activities and maintaining accurate inventory data in the warehouse environment. At the warehouse of PT DSV Solutions Indonesia Site Margomulyo Surabaya, the goods picking process still faces several obstacles, including the use of conventional cardboard that does not support storage order, difficulties in differentiating products with similar characteristics in high-moving SKUs (Stock Keeping Units), and daily demand fluctuations that increase the potential for picking errors, stock discrepancies, and inventory loss. These problems have an impact on decreasing the Overall Warehouse Efficiency (OWE) value. This study aims to analyze the effect of implementing a Jolly Box system integrated with stock classification on increasing OWE and reducing the risk of inventory loss. The study results showed improvements in all OWE indicators, including availability through reduced operational downtime due to sudden reorganizations, performance through zoning of product lines based on movement levels, and quality through reduced risk of picking errors. Furthermore, the system implementation was able to reduce lean waste in the form of defects and unnecessary motion by up to 68% of the total factors causing inventory loss. To ensure the sustainability of the achieved results, regular monitoring of transaction data, routine cycle count implementation, and adjustment of container capacity are required according to the development of managed SKUs.
