Abstract

This study aims to map the process and to measure the performance of supply chain of table tennis at CV Shiamiq Terang Abadi according to SCOR®11.0 model. Furthermore, this study would give suggestion of improvement in order to improve company's performance. The SCOR®11.0 model is considered more complete, systematic and integrated because of its capability in measuring the company's performance from supplier to customer. Data collection in this study was conducted by questionnaire method to CV Shiamiq Terang Abadi which is related directly to the supply chain process. Based on SCOR®11.0 assessment, there are five KPIs that have not reached the company’s target and can be improved: POF, OFCT, USCA, TC and CCCT which has successive gap by 4%, 33 days, 24.05%, 7,38% and 9 days. There are sub-operations within the supply chain become inefficient metrics and need process improvement. The best practices of recomendations are four of the most prioritized: convergence of SCOR model with lean and six sigma, make-tostock goods receipt, ABC inventory classification, and batch size reduction

Abstract

Ethanol, or ethyl alcohol, has many applications in a variety of industries, including as a solvent, fuel, and in pharmaceuticals. Demand for ethanol in Indonesia is high, but domestic production is not sufficient, which prompted the establishment of PT. Indo Acidatama Tbk in 1986. This company produces ethanol from sugar cane molasses through a fermentation process using the yeast saccharomyces cerevisae strain Kyowa. The fermentation process requires good care to ensure optimal results and prevent machine failure. This research aims to measure the Overall Equipment Effectiveness (OEE) value of the fermentation machine at PT Indo Acidatama, identify the factors that influence the production performance of the fermentation machine, and determine the main causes of losses that affect the effectiveness of the fermentation machine. The research results show that the OEE value of the fermentation machine at PT Indo Acidatama in January 2023 is 85%, which is in accordance with JIP standards. The main causes of loss of machine effectiveness are breakdown losses (8.7%), reduced speed losses (5.9%), and rework losses (0.2%). To increase the effectiveness of fermentation machines, it is recommended to adjust process parameters, provide training to staff, and carry out regular data monitoring.

Abstract

The rapid growth of social commerce platforms in Indonesia, particularly TikTok Shop and Shopee Live, has been accompanied by the increasing use of dark patterns, namely manipulative interface designs intended to influence consumer decisions beyond their conscious awareness. Although dark patterns have been extensively studied in global e-commerce and legal contexts, systematic evidence on how these manipulative designs shape digital consumer behavior within the Indonesian social commerce environment remains limited. This study aims to synthesize and map empirical and conceptual literature on the relationship between dark patterns and digital consumer behavior in social commerce through a Systematic Literature Review guided by the PRISMA 2020 protocol. Literature was identified from Scopus, Google Scholar, and Garuda databases published between 2020 and 2026, using keyword combinations related to dark patterns, social commerce, and consumer behavior. After a four-stage screening process, 27 articles met the inclusion criteria and were analyzed thematically. The findings reveal three dominant dark pattern categories operating in social commerce, namely urgency and scarcity cues, social proof manipulation, and forced continuity mechanisms, which influence consumer behavior primarily through impulsive purchasing, reduced perceived autonomy, and erosion of platform trust, consistent with the Stimulus-Organism-Response framework. The review further identifies a substantial research gap regarding the Indonesian social commerce context, where most existing studies remain descriptive and lack a systematic synthesis grounded in consumer behavior theory. This study contributes a conceptual mapping that can serve as a foundation for future empirical research and for regulatory considerations on consumer protection in Indonesia's digital marketplace.
