Abstract

This study aims to evaluate the implementation success of the Pusaka application, which was developed by the Ministry of Religious Affairs of Indonesia. This application is part of a digital transformation initiative that provides public access to religious services such as hajj registration, marriage, and religious education. The DeLone and McLean Information System Success Model is used as the foundational framework to measure system quality, information quality, use, and user satisfaction. This research tests and validates a pre-formulated model and its hypotheses. The testing is based on primary data collected through an online survey administered to State Civil Apparatus (ASN) within the Muaro Jambi Regency's Ministry of Religious Affairs Office. From the distributed questionnaires, a total of 349 responses were declared valid and suitable for further analysis. The quantitative data in this study were analyzed using the Partial Least Square (PLS) method with the aid of SmartPLS V3 software. The analysis stages included testing the measurement model and the structural model. Based on the data analysis, the results indicate the role of the Pusaka application's utilization in supporting the digital transformation of public services at the Ministry of Religious Affairs.

Abstract

Solar panels can be developed to meet the needs of electrical energy. This study was made as a comparison between the costs incurred by Batanghari University when using electricity sources from PLN compared to using electricity sources from solar power plants that are planned, in order to find out the amount of investment costs that are more efficient in a period of months or even years. The design of the calculation of electrical power using SAM, in building A UNBARI. This object was chosen because it uses various electrical loads that are used throughout the day. Load data and total power and electrical energy costs in this building will be used as a comparison for the costs incurred by the planned Hybrid Power Plant (PLTH). The simulation of solar power plants with software with SAM shows that it can almost meet the needs in Building A of Batanghari University and the payback time does not exceed the economic life of a plant, which is 25 years. Based on the results of the study, the PLN PLTS hybrid system project in building A of Batanghari University can be reliably because it meets the eligibility criteria. With data from the results of the calculation of software with SAM, namely a pay back period of 16 years and 4 months, compared to the estimated average lifespan of solar panels which reaches 25 years, the study of PLN PLTS hybrid solar power plants will generate good income for the future.

Abstract

PT PLN (Persero) ULP Telanaipura showed significant improvement in overcoming customer complaints. Customers can now report their complaints practically through the PLN Mobile application or direct visits to the nearest ULP office. This efficiency is driven by the Integrated Complaints and Complaints Application (APKT), a web-based internal system at PLN. APKT is designed to process all types of complaints and grievances received from call centers 123, ensuring prompt response and resolution as per the set time standards. Prior to the implementation of APKT, complaint management was still conventional, not integrated, and without real-time monitoring. The presence of APKT has eased the workload of PLN employees throughout Jambi City rayon, allowing for faster and easier resolution of customer complaints. This study focuses on the effectiveness of the APKT system in customer complaint management at PT PLN (Persero) ULP Telanaipura. If customers have complaints, they can contact the PLN 123 call center. The customer service operator will provide guidance and gather the necessary technical information. The most dominant interference that customers often complain about is interference with the code 99110 (approximately 3.93%), which is often associated with "clear tamper" and "voltage drop" issues. In contrast, the 99115 code disruption, i.e. complaints of misinformation with unidentified causes, is very rare, accounting for only about 0.16%.

Abstract

Accurate temperature monitoring in the furnace is an important element in the processing of steel metals at PT Krakatau Baja Construction. Type S thermocouple sensors are used to measure temperature by converting temperature changes into voltage signals. However, to ensure the accuracy of the readings, thermocouple performance verification is carried out periodically. This research aims to verify thermocouples in several furnace zones to increase the accuracy of temperature data in the Human Machine Interface (HMI) system. The verification process uses the Fluke 17 B+ tool and Universal Transmitter PR4116. The measurement results are compared with the reference table and HMI readings before and after verification. The results show that all thermocouples function well with the largest deviation of 23°C in Zone 2A before adjustment and the smallest deviation of 1°C in Zone 1. Verification succeeded in reducing the deviation, ensuring the reliability of the measurement system. This research confirms the importance of thermocouple verification to improve production efficiency and product quality, with recommendations for regular evaluation of the HMI system and temperature measurements.

Abstract

In the modern era like today, the world is experiencing developments in the field of science and technology. Metaverse technology has become a hot topic of discussion around the world, with its ability to create 3D virtual worlds using AR and VR technology where users can appear to interact in a real virtual world. PT. Semesta Realitas Indonesia (Festivo) is now developing a metaverse that can present a new experience in participating in virtual events/festivals. In making the world of metaverse, PT. Semesta Realitas Indonesia (Festivo) requires a website as a promotional media, information center, managing metaverse events and of course for online ticketing transactions. E-ticket transactions use the Midtrans payment gateway to simplify the payment process. In this study using UML for system design and ERD as part of database design. Then use the Agile Scrum method as a method in system development. This website-based application is built using the HTML, CSS, Javascript, and PHP programming languages, and is assisted by the Laravel and Bootstrap frameworks. The results of this study produce a website-based application that has been tested using Black-box testing with a success rate of 90%, which means the system is classified as good. The application can be used by companies as a media to promote metaverse events, and purchase e-tickets with midtrans to enter the world of metaverse events.
