Abstract

This study aims to determine and analyze the influence of the Work Environment and Work Motivation on the Performance of SD Alam Baiturrahman Bontang Teachers. The type of research used in this study is quantitative. The data analysis method used is multiple linear regression. The population in this study were SD Alam Baiturrahman Bontang Teachers, the number of samples in this study was 30 teachers. Based on the results of hypothesis testing in this study, the Work Environment variable does not affect the Performance of SD Alam Baiturrahman Bontang Teachers, while the Work Motivation variable affects the Performance of SD Alam Baiturrahman Bontang Teachers. Simultaneously or together, the Work Environment and Work Motivation variables affect the Performance of SD Alam Baiturrahman Bontang Teachers. The determination coefficient (R2) value is 0.406 or 40.6%. This shows that the work environment and work motivation are able to explain 40.6% of teacher performance. While the remaining 59.4% is influenced by other variables not examined in this study.

Abstract

This study was conducted to assess the service quality of UMKM Amplang Bontang Store by applying the Customer Satisfaction Index (CSI) and the Retail Service Quality Scale (RSQS). The results indicate that the overall service quality is relatively good, as reflected in a CSI score of 74%, signifying that customers are fairly satisfied with the store’s services. Among the dimensions, social interaction achieved the highest CSI score (83%), while the policy dimension recorded the lowest (63%). Further analysis using the RSQS method identified that the policy dimension has the most significant negative gap (-1.0). Specifically, attribute KB4 (-1.91) emerged as the lowest-performing attribute, making the policy dimension particularly KB4 the primary focus for service improvement.

Abstract

Distribution is a key activity in the supply chain as it is directly related to product delivery to customers. PT Sariguna Primatirta Tbk, the producer of Cleo bottled drinking water, distributes 19-liter gallons from its Samarinda depot using a single vehicle with a maximum capacity of 100 gallons. However, fluctuating demand often leads drivers to choose routes based on perceived shortest distance, which may cause inefficient fuel usage. This study applies the Vehicle Routing Problem approach using the Clarke & Wright Saving Heuristic and Sequential Insertion algorithms. The results show that the Sequential Insertion algorithm reduced the total distance to 294.70 km, achieving fuel savings of Rp57.400.00 (16.30%). In comparison, the Clarke & Wright Saving Heuristic reduced the distance to 320.10 km with fuel savings of Rp32.000.00 (9.09%).
