Abstract

The increasing competition in the manufacturing industry requires companies to continuously enhance productivity in order to maintain efficiency and competitiveness. This study aims to measure the productivity level in the LED lamp production process using the Objective Matrix (OMAX) method combined with Analytic Hierarchy Process (AHP) weighting and Root Cause Analysis (RCA). The data analyzed include labor efficiency, machine utilization, product quality, setup time, and production costs during the period of January to December 2024. The OMAX calculation results indicate that the productivity index fluctuated throughout the research period, with an average value of 281. The highest index was achieved in July at 392, while the lowest occurred in October at 178. These fluctuations reveal instability in resource management and production performance. RCA, supported by the Fishbone Diagram and 5 Whys Analysis, identified the main root causes of decreased productivity: delayed preventive maintenance, inconsistent material quality, and uneven operator skills. Based on these findings, the study recommends implementing preventive maintenance scheduling, conducting regular operator training, and integrating a more comprehensive productivity monitoring system. These improvement efforts are expected to enhance process efficiency, reduce downtime, and ensure sustainable product quality. This research provides practical contributions as a reference for productivity evaluation and strategic decision-making in the manufacturing industry

Ramadan brings significant changes in the shopping and consumption patterns of Indonesians. There is an increase in demand for various types of food and beverages, both for sahur and iftar. The purpose of this study is to map the characteristics of food and beverage purchasing and consumption patterns in a seasonal context (Ramadan): strategic implications for UMKM in the Greater Jakarta area. The research design used is descriptive quantitative with data collection techniques implemented by distributing questionnaires. Then, the questionnaire answers are summarized to obtain the frequency distribution of each item in the questionnaire. The population of this study is people domiciled in the Greater Jakarta area. The sample size was determined using the Lameshow formula, resulting in a sample of 100 respondents spread across the Greater Jakarta area. The majority of respondents, namely 92%, stated that they experienced changes in their shopping patterns during Ramadan. The type of food purchased changed (34%) was the most dominant change. The most dominant consumption purchasing decision during Ramadan was the practicality in preparing food (40%), with favorite shopping places being traditional markets (24%) and street vendors (24%). In a consumption analysis, 83% of respondents experienced changes in their consumption patterns during Ramadan, with the most dominant change being in the amount of food consumed (29%). During sahur (pre-dawn meal), respondents tended to consume vegetables (36%) and chicken (22%). Meanwhile, fried foods (38%) and rice cakes (rice cakes) were the favorite dishes for breaking the fast.
