Abstract

This study aims to analyze the level of service quality and prioritize improvements. The method that used in this study is service quality (SERVQUAL) combined with fuzzy concepts to find out the gap between expectations and consumer perceptions through five dimensions namely tangible, reliability, responsiveness, assurance, and empathy. Fuzzy concepts are used to present uncertainties over respondents' assessment of subjective questionnaires. To determine the priority of improvement, used the Customer Value Index Potential Gains (IPGCV) method. Based on processing data results by using fuzzy-servqual method, it is known that the Tangible dimension has a gap of -0.13, the Reliability dimension has a gap of -0.13, the Responsive dimension has a gap of -0.14, the dimension of Assurance has a gap of -0.12, Empathy dimension has a gap of -0.11. The negative value on fuzzy-servqual assessment can be interpreted that the overall service has not met customer expectations. Achievement of the quality level is equal to 0.8606 which is indicates the quality of services still need improvement because the level of service quality is less than 1. Based on calculation using the PGCV Index, it is known that services which have the highest priority are employees who have adequate support from their institutions so that they can carry out their duties properl

Sama halnya dengan proses bisnis pada umumnya, model bisnis e-commerce juga memerlukan keterlibatan berbagi pihak yang sering disebut dengan istilah Supply Chain Management (SCM). Adanya keterlibatan dari berbagi pihak dalam jaringan supply chain (SC) e-commerce, diperlukan pengukuran kinerja SC untuk melakukan efektivitas yang dilakukan. Tantangannya adalah pengukuran kinerja SC pada e-commerce yang pada umumnya dilakukan pada perusahaan non e-commerce. Paper ini akan membahas tentang identifikasi Key Performance Indicator (KPI) pada pengukuran kinerja SC e-commerce berdasarkan dimensi teknologi informasi melalui studi literatur.

Abstract

The purpose of this study is to measure the value of the bullwhip effect, identify its causes, and find solutions to reduce it. The problem of the bullwhip effect, where their order fluctuations exceed demand fluctuations, resulting in raw material shortages and production stops. This study examines two echelons in the supply chain and uses the FMEA method. The results showed that the bullwhip effect value at echelon 1 (supplier and PPIC) was 1.66, while at echelon 2 (PPIC and Customer) was 0.63. This indicates the presence of a bullwhip effect at echelon 1, while echelon 2 is not affected. Some of the main causes of the bullwhip effect include raw material procurement not meeting orders, material price increases, uncertainty in demand information, large raw material orders and sales volumes greater than raw material receipts. solutions that can be done between suppliers need to implement an information system using E-commerce such as shopee in order to further expand the marketing network and facilitate product distribution to consumers so that online ordering
