Abstract

Human pembagunan Index (HDI) is a composite index that includes three basic dimensions of human development is considered to reflect the status of the population's basic abilities of health, educational attainment, and purchasing power. Data IPM classified into four, namely low, lower middle, upper middle, and high. Therefore, determining the HDI can be done with the data probit regression approach. In the data found that there were similarities between the HDI value of geographically adjacent regions which resulted in the classification of the adjacent HDI same region. This is presumably due to the inter-regional dependency. This phenomenon is suspected because of the spatial dependencies can be described through spatial methods. From the explanation above, the HDI of data in this study are based on the spatial probit regression method are compared with the probit method. This study aims to assess the predictors for estimating parameters and testing parameters were applied to the data classification IPM in Java. MCMC is used as a method of estimating the parameters in the assessment. While the assessment test parameters used are 25% to 75% of the estimated parameters

Abstract

Surabaya is the center of a growing manufacturing industry that always strives to improve the quality of its products. One company that faces serious problems is PT. BKI, which faces a high rate of innerbox defects with potential negative impact on product quality. The study used Six Sigma methodology to identify and address the root cause of innerbox defects within two months. The results of the analysis show that the main causes of innerbox defects include structuring, material, management, environmental problems, as well as improper assembly methods. The proposed solution involves the use of duplex-type cardboard materials, improved assembly techniques, regular machine maintenance, and environmental control. The use of stripping bands instead of duct tape on innerbox packaging is an effective improvement. The implementation of control for two months showed an increase in sigma value from 2.94 to 2.83. The Six Sigma approach is proven to provide a systematic analytical foundation for significant improvement. The results help PT. BKI in improving quality, efficiency, and customer satisfaction

Abstract

The rapid expansion of the e-commerce sector has imposed considerable demands on Usaha Mikro, Kecil, dan Menengah (UMKM) to enhance the operational efficiency of their logistics warehouses. This study aims to improve organizational performance and employee well-being at Tokonekoncoku, a logistics UMKM, through an ergonomic workplace redesign. The research employs the Define, Measure, Analyze, Design, Verify (DMADV) methodology, emphasizing Critical to Quality (CTQ) parameters to ensure that the proposed interventions are both contextually relevant and quantitatively measurable. The CTQ priorities identified include operational time efficiency, productivity enhancement, and workforce satisfaction. By systematically implementing ergonomic principles—encompassing layout reorganization and workstation modifications—the study demonstrates a significant improvement in the efficiency and comfort of the work environment. The findings underscore that the integration of ergonomic design within the DMADV framework offers a robust approach to simultaneously advancing operational performance and promoting worker well-being in UMKM logistics settings.

Abstract

Irregularities in truck queueing during the loading process at the Finished Goods Warehouse Department of PT. SGB have led to repeated complaints from logistics partners, disrupting operational efficiency and damaging the company’s reputation. This study aims to identify the root causes of the issue and propose corrective actions using the Theory of Constraints (ToC) approach. The methods employed include direct observation, in-depth interviews, and structured brainstorming sessions. The analysis revealed three main root causes: the absence of updated queue information for drivers, lack of a standardized document verification procedure, and unavailability of clear priority loading information. The implemented solutions consisted of queue information boards, a ticketing system managed by security personnel, and strengthening the role of warehouse team leaders in communication and oversight. Evaluations conducted from June to February 2025 showed a significant reduction in complaints, improved queue discipline, and decreased overtime costs. This study recommends standardizing operating procedures (SOPs), conducting regular training sessions, and adopting a digital queuing system as a long-term sustainability strategy.
