Abstract

The continuity of the supply of electric power is becoming a greater demand from consumers. Feeder MRA05 GI Mrica Banjarnegara supplies electrical energy for parts of Banjarnegara Regency until 2020 has 4 distributed generations, namely PLTMH Sigebang 500 KW, PLTMH Kincang 320 KW, PLTMH Adipasir 320 KW, PLTMH Rakit 500 KW. Based on recorded data in 2020, the MRA05 feeder experienced 15 blackouts/year, with a total outage duration of 38.68 hours/year, of course it was enough to disrupt the continuity of the distribution of electrical energy to consumers. This research discusses the magnitude of the reliability index (SAIFI, SAIDI, CAIDI) when the DG is not installed and installed. The calculation of the magnitude of the reliability index was carried out using the Reliability Index Assessment (RIA) method, the calculation results were compared with the results of the ETAP 12.6.0 software simulation. The reliability index is based on the RIA method when DG is not installed, the SAIFI value is 2.96228 interruptions/year, the SAIDI value is 9.1185 hours/year, the CAIDI value is 3.078 hours/interruption, When DG is installed, the SAIFI value is 2.96228 disturbances/ year, the SAIDI value is 7.567 hours/year, the CAIDI value is 2.5546 hours/interruption.

Abstract

The rapid adoption of Internet of Things (IoT) technologies by startups has intensified concerns related to data governance, privacy protection, and information security risks. This study investigates the effect of IoT data governance quality and data privacy policy on information security risk mitigation and customer trust in IoT-based startups in Bandung, Indonesia. Using a quantitative research approach, data were collected from 150 users of IoT-based startup services through a structured questionnaire measured on a Likert scale. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS 3). The results indicate that IoT data governance quality has a significant positive effect on information security risk mitigation. In addition, data privacy policy and information security risk mitigation both have significant positive effects on customer trust. Furthermore, information security risk mitigation partially mediates the relationship between IoT data governance quality and customer trust. These findings highlight the importance of strengthening data governance frameworks and implementing transparent privacy policies to reduce security risks and enhance customer trust. This study contributes to the growing body of literature on IoT governance and provides practical insights for startup managers and policymakers in fostering secure and trustworthy IoT-based business environments.

Abstract

The rapid adoption of Industry 4.0 technologies has encouraged manufacturing companies to integrate Internet of Things (IoT) solutions and production tracking systems to improve operational performance and delivery reliability. This study aims to analyze the impact of IoT implementation and production tracking systems on delivery timeliness in the electronics industry in Tangerang City. A quantitative research approach was applied using survey data collected from 150 employees involved in production and logistics activities. Data were measured using a five-point Likert scale and analyzed through Structural Equation Modeling–Partial Least Squares (SEM-PLS 3) to evaluate both measurement and structural models. The results indicate that IoT implementation has a positive and significant effect on delivery timeliness by enabling real-time monitoring and faster operational coordination. Production tracking systems also show a strong positive influence by improving scheduling accuracy, workflow visibility, and decision-making processes. Furthermore, the integration of IoT and production tracking technologies contributes to better supply chain responsiveness and reduced delivery delays. These findings highlight the strategic role of digital monitoring systems in enhancing manufacturing performance and meeting customer delivery expectations. This study provides empirical insights for practitioners and contributes to the growing literature on smart manufacturing and technology-driven operational efficiency in Indonesia’s electronics sector.
