Abstract

The effectiveness of equipment on the bottling packaging line greatly determines throughput and quality in the high-capacity beverage company. Overall Equipment Effectiveness (OEE) is commonly used to assess performance and map sources of loss. This study evaluates beverage company bottling line using OEE and six big losses based on weekly data from weeks 14–26, including production output (good, reject, total), available time, planned downtime, and unplanned downtime. OEE components were calculated (Availability–Performance–Quality) and decomposed into breakdown, setup & adjustment, idling & minor stoppages, reduced speed, and defect. The results showed an average OEE of 69.35% (68.03–70.79%) with availability at 97.9%, performance at 70.9%, and quality at 99.9%. The dominant loss was reduced speed (≈28.48% of loading time), while setup & adjustment was 0.95%, breakdown 0.89%, idling & minor 0.24%, and defect 0.0895%, which were relatively small. The findings confirm performance as the main constraint; improvements are directed at stabilizing the Filler speed (pacemaker), line balancing & buffering, controlling micro-stops, and predictive maintenance of critical points. Improving performance is projected to be the most effective way to bring OEE closer to the 85% benchmark without compromising quality.

Abstract

This Industrial Internship (Prakerin) was conducted at PT. Perkebunan Nusantara IV Regional II, Plantation Unit, and Adolina Palm Oil Mill (PKS). It focused on analyzing the effect of crude palm oil (CPO) thickness in the Continuous Settling Tank (CST) on CPO impurity levels. The issue raised was the persistent variation in impurity levels in CPO, which is suspected to be influenced by the thickness of the oil layer during the collection process. This study aimed to determine the relationship between CPO thickness in the CST and the resulting impurity levels. The method used was CPO sampling at several oil thicknesses (33–46 cm), followed by laboratory impurity analysis using Gooch Crucible Filter filtration and gravimetric calculations. Data were obtained during the period July 4–11, 2025. The results showed that at a thickness of 45–46 cm, the lowest impurity content was 0.01%, while at a thickness of 33 cm, the highest impurity content was 0.04%. At a thickness of 35 cm, the impurity content was 0.03%, and at a thickness of 40 cm, it was 0.02%. This indicates an inverse relationship between CPO layer thickness and impurity content, where the thicker the oil layer, the lower the impurity content. Therefore, it can be concluded that maintaining a minimum oil thickness in the CST tank of ±40 cm is a crucial step in maintaining CPO quality and ensuring it meets industry standards.

Abstract

This study aims to determine the impact of controversial figures in marketing strategies in the skincare industry. The research focuses on three public figures: Nikita Mirzani, Dr. Richard Lee, and “Dokter Detektif." This study uses a qualitative study approach to explore the polarization of public image and the role of celebrities in influencing consumer perceptions, brand trust, and purchase intent. Data was collected through social media content analysis, online media documentation, and a literature review of previous studies. The findings reveal three core themes: (1) controversial personal branding attracts engagement and emotional resonance, (2) buzz marketing tactics trigger virality through peripheral cues rather than rational persuasion, and (3) consumer ambivalence emerges between entertainment value and brand credibility. However, the use of controversy also poses long-term reputational risks for the associated brands. Although this study is limited to qualitative methods, it offers theoretical insights and practical recommendations for ethically managing influencer campaigns in culturally sensitive digital markets.
