Abstract

This research aims to design a dynamic system model for the downstream copper processing industry. The secondary data obtained is data provided by the BKPM Strategic Investment Downstreaming Expert Team. Vensim software is used to simulate downstream development in the form of CLD and SFD from 2024 to 2045. The results of the value-added simulation resulted in an increase in the added value of copper cathode by 2.15 times, the added value of cathode slab by 1.62 times, the added value of copper billet by 1.65 times, the added value of copper bar &rods by 1.08 times, the added value of copper tube by 1.02 times, the added value of copper strip by 1.39 times, and the added value of copper wire by 1.58 times. After a sensitivity analysis of the selling price at CAGR and an increase in energy costs by 20%, there was a change in the average value-added margin, so that the increase in added value changed which resulted in an added value of copper cathode of 1.9 times, added value of cathode slab of 1.47 times, added value of copper billet of 1.49 times, added value of copper bar &rods of 1.26 times, added value of copper tube of 0.93 times, added value of copper strip of 0.98 times, and added value of copper wire of 1.44 times.

Abstract

The business process of the J20 production department is currently experiencing obstacles in terms of information delivery, production report, maintenance report, and problem information that causes decision making is often irrelevant. This is due to the use of paper media with a long bureaucratic flow so that the cycle time becomes inefficient. This study used business process reengineering, modeling business process in business process modeling notation (BPMN), and supporting research problem analysis used fishbone diagram. The result showed changes in a process flow, job desk, unit elimination, and proposed design of information systems in the form of application software as a solution to the problems studied, so that it is expected to obtain process time efficiency of 65.1% and cycle time of 99.2% of the previous total time. Proses bisnis departemen produksi J20 saat ini mengalami hambatan dalam hal penyampaian informasi, laporan hasil produksi, laporan maintenance, serta informasi problem, yang menyebabkan pengambilan keputusan sering kali terjadi bias. Hal ini di sebabkan oleh penggunaan media kertas dengan alur birokrasi yang panjang sehingga waktu siklus menjadi tidak efisien. Pada penelitian ini digunakan metode Business Process Reengineering, dengan memodelkan bisnis proses dalam Business Process Modelling Notation (BPMN), serta pendukung analisa masalah penelitian digunakan diagram tulang ikan. Hasil penelitian menunjukan adanya perubahan alur proses, jobdesk, eliminasi unit, serta usulan perancangan sistem informasi berupa software aplikasi sebagai solusi dari permasalahan yang diteliti, sehingga diharapkan dapat diperoleh efisiensi waktu proses sebesar 65,1% dan waktu siklus sebesar 99,2% dari total waktu sebelumnya.

Abstract

This study aims to assess the implementation of smart city innovations in West Bandung Regency in 2024, focusing on evaluating user satisfaction with the priority applications that have been launched. The research method uses the Unified Theory of Acceptance and Use of Technology (UTAUT) model to measure Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions variables, as well as their impact on customer satisfaction. Data were collected through questionnaires from public servants associated with 37 smart city innovations. The results showed that Smart Branding: Visit KBB had the highest Performance Expectancy and Facilitating Conditions scores, while BA QRIS and Smart Branding: Visit KBB applications had the highest Effort Expectancy scores. The implications of this research are to provide recommendations for improving the effectiveness and acceptance of smart city applications in West Bandung Regency, as well as providing insights for the development of future smart city programs.
