Abstract

The use of palm oil waste as boiler fuel is one of the innovative solutions in supporting the use of renewable energy while reducing the environmental impact of palm oil industry waste. Waste such as palm shells, mesocarp fibers, and empty oil palm bunches have high energy potential through direct combustion and other thermal technologies. This study aims to evaluate the potential use of palm oil waste as boiler fuel based on its calorific value, combustion efficiency, and environmental impact. The methods used include analysis of the physical and chemical characteristics of waste, boiler performance tests, and exhaust gas emission evaluation. The results show that palm oil waste has a high calorific value (15–20 MJ/kg), which makes it an efficient alternative fuel. In addition, the use of this waste is able to reduce dependence on fossil fuels while minimizing carbon emissions, thereby supporting the greenhouse gas emission reduction target. From an operational perspective, the use of palm oil waste in industrial boilers can increase combustion efficiency by up to 75–85%, depending on fuel conditions and boiler design. This makes palm oil waste not only economically valuable, but also strategic in supporting the transition to clean energy. Another advantage is that waste management becomes more targeted, because solid waste that is usually only an environmental burden can be reused as an energy source. However, some of the challenges that need to be considered include relatively high ash levels, the potential for corrosion in boiler equipment, and the need for emission control technology to comply with environmental standards. With the right mitigation strategy, palm oil waste can be processed into sustainable and environmentally friendly energy.

Abstract

The hospital operating room is one of the most crucial facilities in health services, so it requires a stable, reliable, and uninterrupted electricity supply to ensure patient safety and smooth medical procedures. The slightest electrical outage can pose a major risk, given that almost all vital medical equipment in the operating room relies on an electrical power supply. Therefore, the Uninterruptible Power Supply (UPS) system has an important role as a backup solution to ensure the continuity of electrical energy. This study aims to analyze the performance, capacity, and burden of UPS at Siti Fatimah Palembang Hospital using quantitative methods. Data was obtained through direct observation, interviews with technicians, technical documentation, and measurement of current and load power with standard-compliant measuring equipment. The focus of the analysis was directed at the Online Double Conversion type UPS with a capacity of 20 kVA which functions as the main supplier of backup electricity in the three operating rooms. The measurement results show that the total load reaches 8,855.5 VA or equivalent to 44.2% of the total capacity of the UPS. This load comes from 24 units of vital medical equipment, including operating lights, patient monitors, ventilators, anesthesia machines, and electrosurgical devices spread evenly across three operating rooms. With a power factor of 0.92 and a measurement current of 39.8 A, the performance of the UPS is quite efficient and safe to use. This shows that UPS capacity still has spare space to bear additional loads in the event of an increase in the number of medical equipment in the future. The conclusion of this study is that UPS at Siti Fatimah Palembang Hospital is able to work optimally in maintaining the stability of power supply, so that it can ensure the continuity of critical medical services in the operating room.

Abstract

The increasing number of motorcycle thefts in various regions indicates that conventional security systems are not yet fully effective in protecting vehicles, necessitating new technology-based innovations. This study discusses the planning and implementation of a motorcycle security system utilizing Radio-Frequency Identification (RFID) technology as a more responsive and modern solution. The system is designed using a passive RFID tag placed on the motorcycle key, an RFID reader integrated with the motorcycle unit, and an Arduino microcontroller that functions to control the ignition system. With this combination, the motorcycle can only be activated if the appropriate tag is detected, while access attempts using an invalid tag or the loss of the tag will automatically disconnect the ignition system. Test results announced that tag recognition can be done very quickly, in less than a second, so as not to disrupt the user's comfort when starting the vehicle. In addition, this system is able to maintain consistent performance by providing an automatic response that supports advanced security. The implementation of this plan is expected to reduce motorcycle theft by providing an additional layer of security that is more difficult to penetrate than a manual key system. From the user's perspective, this technology remains practical because it does not require complicated procedures in its operation, simply by ensuring the appropriate RFID tag is attached to the motorcycle key. Overall, this research confirms that the application of Arduino microcontroller-based RFID technology can be an alternative, inexpensive, and applicable security system in everyday life. It is hoped that this system will not only improve protection for vehicle owners but also serve as a benchmark for the development of more sophisticated transportation security technologies in the future. Implementation of this system is expected to reduce motorcycle theft and provide a greater sense of security for vehicle owners.

Abstract

Administrative services for civil servants (ASN) play a crucial role in ensuring the rights and obligations of government employees. One of these services is the submission process for the Wife Card (KARIS) and Husband Card (KARSU), which serve as official proof of marital status for civil servants. At the BKPSDM of Sumba Barat Daya, the current submission process for KARIS and KARSU is still carried out manually by filling out paper forms and attaching physical documents. This manual method is time-consuming, prone to data errors, and complicates the monitoring process. Therefore, this study aims to develop a digital information system to simplify the submission, verification, and issuance process of KARIS and KARSU online. This research applies a Research and Development (R&D) approach using the Waterfall model, consisting of requirement analysis, system design, implementation, testing, and evaluation stages. The system is developed using the Python (Streamlit) programming framework and a SQLite3 database, designed to be easily accessible to both ASN users and BKPSDM officers through local networks or the internet. The results show that the developed system successfully reduces processing time by up to 60%, improves data accuracy by 90%, and significantly decreases the use of physical documents. The implementation of this digital information system makes the KARIS and KARSU administrative service more efficient, transparent, and accountable, supporting the ongoing digital transformation within the local government of Sumba Barat Daya Regency.

Abstract

Public transportation, with Transjakarta as its main pillar, requires a deep understanding of customer behavior to improve service quality and maintain loyalty. This study aims to segment Transjakarta customers using data mining techniques, specifically the K-Means Clustering algorithm, based on the RFM (Recency, Frequency, Monetary/Value) behavioral model. 37,900 rows of raw transaction data were processed into a clean database, resulting in 1,917 unique customers for analysis. The RFM metrics were then normalized using Min-Max Scaler. The optimal number of clusters was evaluated using the Elbow Curve and Silhouette Score Methods, which led to the determination of k = 4 clusters. The segmentation results identified four customer groups requiring specific strategies: Cluster 3 (Champions) with high R, F, and V (requiring rewards and retention); Cluster 0 (Active, Low Value) with high R and F but low V (requiring upsells and cross-sells); Cluster 1 (Potential/At-Risk); and Cluster 2 (Dormant/Lost). Preliminary analysis (EDA) showed that nearly half of customers (49.3%) used Bank DKI cards, dominated by the productive age group (25–45 years old), with the Rusun Kapuk Muara–Penjaringan route being the busiest. The main managerial recommendation is to strengthen the partnership with Bank DKI and optimize services in this busy corridor.

Abstract

The development of information and communication technology (ICT) is an important demand in the world of education, especially at the Vocational High School (SMK) level which prepares students to enter the digital-based world of work. However, students in class X of SMKS Efata still show delays in mastering ICT which has an impact on the learning process and their competency readiness. This study aims to analyze the factors that cause students to delay in mastering ICT as well as identify strategic steps to improve their skills. The research method used is a qualitative descriptive approach with data collection techniques through observation, interviews, and documentation. The results of the study show that the limitations of technology facilities, the lack of experience of students using computer devices before entering vocational schools, and the low intensity of ICT learning practices are the dominant factors that affect the delay in mastering technology. In addition, the difference in students' backgrounds in digital literacy and the lack of assistance during the learning process also slow down the development of their abilities. Nevertheless, students have good motivation to learn and adapt to technology if they are given the support of the right learning facilities and strategies. The conclusion of this study emphasizes that improving facilities, strengthening practice-based learning methods, and intensive mentoring are needed to accelerate students' ICT mastery. This research is expected to be the basis for schools in formulating ICT learning policies that are more effective and in accordance with the needs of technological developments.
