The Terminal Loading Area (TLA) API at PT Pertamina Hulu Mahakam functions as a facility for processing oily water before being discharged into the environment. One of the main issues faced is the accumulation of thick floc (oil clumps) due to high emulsions in crude oil, along with the malfunctioning water spray valve on line 1, causing operators to resort to manual spraying using hydrant water. This increases the risk of exposure to hazardous chemicals such as Benzene, Toluene, and Xylene (BTX), which poses a health threat to workers. Therefore, improvements to the water spray system are needed to reduce BTX exposure and enhance the effectiveness of oil-water separation. This study aims to analyze the effectiveness of proposed improvements to the water spray system to reduce BTX exposure and improve the efficiency of oil-water separation. The methodology used includes literature review, field study, and technical testing. Proposed solutions include replacing or repairing the damaged water spray valve, adding piping networks to compartment 2 to distribute water more evenly, and using treated water (produced water) to optimize the system and reduce reliance on hydrant water. The results of the study indicate that replacing or repairing the water spray valve, adding piping networks, and using produced water effectively reduce BTX exposure while maintaining oil recovery effectiveness. The trials also showed that using the Oil Pump (P-3230 & P-3235) provides optimal pressure (8–9 barg) for water spray, compared to the less effective Water Pump (P-3200 & P-3205). Implementing these solutions is expected to reduce BTX exposure for workers, improve oil-water separation efficiency, and contribute to a safer and more efficient working environment.

This study aims to analyze the effect of variations in the Continuously Variable Transmission (CVT) spring constant and the type of fuel on the performance of a 110 CC gasoline motorcycle engine. The CVT system is one of the important components in an automatic motorcycle that functions to transmit power from the engine to the rear wheels efficiently. CVT performance is greatly influenced by the spring constant used, because this component is directly related to the automatic gear ratio shifting process. On the other hand, the type of fuel also has an important role because it is related to the quality of combustion and the efficiency of energy produced by the engine. The test results show that the use of a CVT spring with a constant of 18.05 N/cm combined with Pertamax fuel is able to provide the best engine performance. In this configuration, the engine reaches a maximum power of 7.84 HP at 8200 rpm and a maximum torque of 9.30 Nm at 6200 rpm. This combination is proven to be the most optimal in increasing power and torque, thus providing more responsive acceleration. Furthermore, the use of a CVT spring with a constant of 25.20 N/cm combined with Pertamax also shows quite good performance, namely with a maximum power of 7.38 HP and a maximum torque of 8.56 Nm. Although the results are not as high as the first configuration, this combination is still quite effective in improving engine performance. Meanwhile, when using a spring with a higher constant of 33.69 N/cm, the resulting power tends to decrease to 7.02 HP with a torque of 8.02 Nm. In addition, the initial acceleration in this configuration is less responsive so it is not recommended for optimal performance.

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.

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.

In the context of post-pandemic economic recovery in the 2022–2024 period, bank sustainability and resilience, particularly in terms of profit-generating ability, are crucial aspects to consider. This study was conducted to analyze the extent to which capital structure and intermediation efficiency influence the profitability of banks listed on the Indonesia Stock Exchange. Capital structure in this study is proxied by the Capital Adequacy Ratio (CAR), while intermediation efficiency is measured by the Loan to Deposit Ratio (LDR). The profitability indicator used is Return on Assets (ROA), which reflects a bank's effectiveness in utilizing its assets to generate profits. This research methodology uses a quantitative approach through multiple linear regression analysis with secondary data in the form of annual financial reports from 111 banks for the 2022–2024 period. The analysis results show that simultaneously, CAR and LDR variables have a significant effect on ROA. Furthermore, both variables have been shown to contribute positively to increasing bank profitability. In other words, maintaining adequate capital and efficient credit management can strengthen overall financial performance. This finding offers strategic implications for bank management in formulating capital and liquidity management policies. Optimizing these two aspects not only impacts short-term profit achievement but also contributes to the stability and sustainability of banking profitability in the long term. Therefore, banks need to ensure a strong capital strategy coupled with efficient intermediation to be more resilient in facing future economic dynamics.

Abstract. The advancement of broadcasting technology has driven the demand for reliable and efficient automation systems, particularly in managing the transition from broadcast content to advertisement segments. In this context, the present study proposes the application of the Single Tone Trigger (STT) method as an automatic triggering mechanism to systematically regulate content switching. This method utilizes a single-frequency audio signal embedded within the primary broadcast, which can be detected by the receiving system. The detection of this signal initiates an automatic content transition without requiring intervention from playout operators. A key advantage of this approach lies in its ease of integration with conventional broadcasting systems and its ability to reduce manual involvement that has traditionally been essential in broadcast content management. Through a series of tests, the system demonstrated high signal detection accuracy, low latency, and optimal operational reliability. These findings indicate that the Single Tone Trigger method can significantly enhance workflow efficiency within the broadcasting industry. Overall, this approach presents substantial potential for broad implementation as an automation solution that is not only stable and cost-effective, but also adaptive to the operational demands of modern broadcasting.   Keywords: Automatic Transition, Broadcast Automation, Single Tone Trigger (STT).

The manual credit application process often takes a long time and is prone to various problems, such as recording errors, data redundancy, and the risk of losing important documents. These conditions not only hamper service effectiveness but can also reduce customer satisfaction and the performance of the officers involved. Therefore, this study aims to design and develop a Progressive Web App (PWA)-based credit application system using the Rapid Application Development (RAD) method. This system is expected to be a more efficient, faster, and more accurate solution than the current manual mechanism. PWA was selected based on its ability to provide universal access through a browser without the need for additional application installation, making it more practical for both customers and officers. Meanwhile, the RAD approach allows for an iterative and flexible system development process, with direct user involvement from the design stage through implementation. This aims to ensure the system is truly aligned with real-world needs. The development results indicate that the designed PWA system is capable of supporting the tasks of Account Officers (AO) and Division Heads in managing credit application data. The process includes the pipeline stage, submission, field survey, and credit realization, which is well-documented and accessible in real time. Functional testing using the Black Box Testing method proved that all features functioned according to established specifications. Furthermore, usability testing using the System Usability Scale (SUS) method yielded satisfactory scores, indicating the system's high usability and positive user experience. Therefore, this PWA-based credit application system not only improves process effectiveness and efficiency but also supports transparency, data accuracy, and user satisfaction.

Black Soldier Fly (BSF) larvae, or maggots, are a type of insect currently widely cultivated, primarily for animal feed. This is because BSF larvae contain essential nutrients such as fat and protein in high amounts, thus improving the nutritional quality of livestock that consume them. Therefore, the processing and preservation of maggots is crucial to maintain their nutritional content and extend their shelf life. One method used in maggot processing is drying. Drying aims to reduce the water content in the larvae, thereby preventing the growth of microorganisms that cause spoilage. One widely applied technique is drying using a microwave oven. However, before the actual process is carried out, simulations are often required to determine the distribution of heat and humidity. Simulation is one of the most effective ways to predict the drying performance of biological materials. This study used a simulation using the Computational Fluid Dynamics (CFD) method operated by Comsol Multiphysics 6.2 software. The parameters used in the simulation were an initial maggot temperature of 80°C, a drying time of 15 minutes, and a heat source of 1300 W/m³. Based on the simulation results, the final water content of the maggots was below 10%. Furthermore, the final relative humidity of the maggots ranged from 10–35%, while the final temperature of the larvae increased to 93–97°C. These results indicate that microwave drying can effectively reduce moisture content while maintaining the nutritional quality of BSF larvae. These simulation results can be used as a basis for practical maggot drying processes, thus supporting the production of efficient and nutritious animal feed.

Furthermore, the motivation and commitment of the officials in delivering services should be strengthened. The existing service systems and procedures are not fully efficient, so continuous evaluation and improvement are necessary to enhance the quality of services in the future.

The production process of graphite glass at ABC faces challenges in the form of waste that has an impact on low operational efficiency. Waste in production activities can affect the quality, cost, and timeliness of product completion. This study aims to identify the most dominant types of waste and provide relevant improvement recommendations to improve production efficiency. The method used is Value Stream Mapping (VSM), a visual approach that maps the flow of the production process from raw materials to final products. The research stage is carried out through direct observation on the production floor, time study, interviews with employees, and documentation of production activities. The results of the analysis show that the most dominant form of waste is overprocessing, which is a repetitive activity that does not add value to the product. This causes longer production cycle times and reduces the effectiveness of resource use. To overcome this, this study provides several recommendations, including: combining production processes that have similar functions, redesigning workflows to make them more concise, and eliminating activities that do not provide added value. The implementation of this improvement has proven to be effective by increasing the Process Cycle Efficiency (PCE) value from 45% to 67%. The increase in PCE reflects that the production process has become more efficient, the workflow is smoother, and the rate of waste has decreased significantly. In addition, the results of this study also confirm that the application of the VSM method can be a strategic solution in identifying sources of inefficiency, designing continuous improvements, and increasing the competitiveness of companies. Thus, the company is expected to continue to evaluate, control, innovate, and improve technology so that efficiency achievements can be maintained, expanded, and improved consistently and sustainably in the future.
