Abstract

This study aims to determine the best supplier for in-Lite lighting products. The company chose criteria and sub-criteria in supplier selection to optimize product sales continuity. This study used the Analytical Hierarchy Process (AHP) method, which provided information about the criteria, sub-criteria, and alternatives in the selection of three suppliers: A, B, and C. The existence of priority weights provided a decision in choosing the supplier of the lighting product. The new criteria and sub-criteria were the results of the literature study formulation and then adjusted again with the results of the interview. Seven criteria were determined in this study: production, price, quality, site selection, product suitability, delivery, and service. The results of the calculation of the priority weights of the criteria, sub-criteria, and alternative selection using a questionnaire. The parties involved in the selection of suppliers filled out the questionnaire to obtain a weight for each supplier. Based on the results of AHP calculations, supplier A got the highest weight of 0,442 or 44%, so this supplier is used as a company priority in choosing suppliers for in-Lite type lighting products.

Abstract

The oil palm is the most productive plantation product in Indonesia. Government strategies and policies related to oil palm plantations continue to be carried out considering that the plantation area is increasing every year. Segmentation of oil palm plantations based on area, production, and productivity aims to identify groups of potential oil palm plantations in the territory of Indonesia. This segmentation can provide consideration in formulating strategies and policies that will be made by the government. The segmentation method for grouping oil palm plantations uses the K-Means Clustering Data Mining technique with 3 clusters specified. Data mining stages start from data collection until representation is carried out, where 34 data sets are collected, only 25 data sets can be processed further. The results of this grouping obtained three plantation segments, namely 72% of the plantation group with low potential, 20% of the plantation group with medium potential, and 8% of the plantation group with high potential.

Abstract

Rapid technological developments greatly affect the demand for products and services. So the industry needs to improve to maximize production achievements in order to meet market needs. The development of industry 4.0 provides an opportunity to revitalize the Indonesian manufacturing sector. Moreover, the Ministry of Industry has compiled "Making Indonesia 4.0" as a strategy and roadmap to develop industry 4.0 in Indonesia. Indonesia focuses on five main sectors for the development of industry 4.0, including the food and beverage, chemical, electronics, textile and clothing, and automotive industries. This research was conducted to determine the level of readiness of the manufacturing industry, especially the food and beverage industry at PT. Perkebunan Nusantara VIII to face industry 4.0 based on organizational and technological aspects. The measurement method used is the Indonesia Industry 4.0 Readiness Index (INDI 4.0). With these results, it can help the industry know the current level of achievement and know what needs to be done to get to the level of industry 4.0. Based on online and offline assessments carried out at the level of readiness, the people and culture aspects as well as the technology aspect have the highest level of use but are at Level 2. The technological aspect has the lowest readiness at Level 1. Overall, the company's readiness is at Level 1 (readiness stage). early) almost reached moderate readiness (Level 2).

Abstract

Quality control is intended to maintain and improve quality and maintain the safety of the products produced. This study uses Statistical Process Control by using several tools such as check sheets, control charts and fishbone diagrams to determine the cause of the decline in quality in tea with the aim that the next process can minimize the level of product quality decline. This study aims to determine the dominant cause of the decline in tea quality when viewed from the water content in tea. Based on the results of the study, it can be seen that the dominant cause of the decline in tea quality is the highwater content of dry tea. This type of deterioration can be caused by human error and other factors such as machine condition, raw materials and process monitoring.

Abstract

Bulk olein is one of the products produced by Palm Oil Processing Company. Bulk cooking oil controls 75 percent of the production market share in Indonesia and about 77.5 percent of households in Indonesia use bulk cooking oil because the price is cheaper than packaged cooking oil. Demand for olein in the future is predicted to be continued to increase, so it is necessary to estimate future sales so that production activities become more effective and efficient. The method used in this study is the double moving average (DMA), which is one of the forecasting methods with data that has a trend. The calculation will be done by comparing the result of 3 moving, 4 moving and 5 moving. Forecasting error is calculated using mean absolute percentage error (MAPE). The calculation results show that the average MAPE from DMA with 5 moving has the smallest value. To verify these results, an analysis of the processed data was carried out, namely looking for data with the furthest distance from the linear line, namely t3 data and t7 data. The data is omitted in data processing and then the MAPE error value is recalculated. The results obtained are that DMA with 3 moving results have the smallest error, which is 11.863 percent. For this reason, the chosen forecasting calculation is a double moving average with 3 moving.
