Abstract

The English Proficiency Test (EPrT) is a prediction test for English as a Foreign Language (TOEFL), which is a prerequisite for graduation at XYZ University. The Language Center provides a course for EPrT preparation. The course posttest data shows that only 74% of students met the graduation prerequisites. This study aims to develop an English course design based on the students’ English skill cluster. This study uses the K-Means clustering approach to classify the students based on English skills. The respondents are 397 students who joined the EPrT preparation course in October and November 2018. The 397 students are distributed into 3 clusters, which are 174 students in cluster 1, 116 students in cluster 2, and 107 students in cluster 3. Cluster 1 consists of students with the score below average. Cluster 2 consists of students with the total score above average, but the components score is below average. Cluster 3 consists of students with pre-test total score below average, but the post-test score are above average. Therefore, the EPrT preparation course is suggested to have different levels, instead of one level as now. The course materials are designed to be suitable for students’ initial English skills at each level.

Abstract

The Palm Oil Supply Chain (POSC) is a series of companies dealing with materials or products derived from oil palm fresh fruit bunches. The chain is interdependent sequentially and cooperate in the control, management and improvement of the flow of products, money and information from the upstream side to the downstream side. The POSC consists of palm oil seed growers, farmers, traders, CPO factory, refinery factory, distributor/retailers, and consumers. The first party in the chain is the palm oil seed or seedling growers. These growers have a very important role for palm oil farmers because the quality of the seeds determines the quality of further fruits. The aims of this study are to evaluate the feasibility study of growing the seedlings, and measure the sensitivity of the factors to the profitability. By using modified Hayami method for the supply chain, the added value obtained is Rp5.950.227.861 which is 34,73% of the sales. The feasibility analysis calculation with an interest rate of 13.5%, shows the NPV of Rp 38.439.321.865, with the BEP of Rp 828.430.058, while ROI result 78,62%, Payback Periode value 1,27, Modified B/C Ratio 1,69, and IRR 78,33%.

Abstract

Freight forwarding is a logistics company which provide land delivery services rely heavily on trucking vendors. The available trucking vendors may not fulfill the company's expectations. Therefore the research was conducted to analyze the performance, selection process, management and development of 26 trucking vendors. The research began with the formation of a Critical Success Factor (CSF) and its development, namely a Key Performance Indicator (KPI) in accordance with company objectives. Then the CSF and KPI was weighted through the Analytic Hierarchy Process (AHP) method, determined the optimal performance value of each KPI, measured the performance of each vendor through the scoring method, analyzed the performance of the trucking vendor that was not optimal through Root Cause Analysis (RCA) by looking for the cause based on fishbone diagrams and FMEA tables, as well as providing suggestions regarding the management and development of trucking vendors. The results of the study were 11 CSFs and 28 KPIs that were formed. Based on the selection process conducted on 26 trucking vendors, there are 3 excellent vendors, 4 very good vendors, 11 good vendors, 3 matching vendors, and 5 unsatisfactory vendors. Furthermore, researcher conducted root cause analysis (RCA) of vendor representatives “matching” and “unsatisfactory” categories with fishbone diagrams and FMEA tables. Where the 5 highest RPN values from the FMEA table were given suggestions for improvement. Meanwhile, the excellent, very good, and good vendor categories are developed through strategic plans for the future.
