Abstract

Conventional power plants that exist today can cause environmental damage, such as air pollution and the erosion of fossil reserves. Therefore, humans continue to innovate to develop environmentally friendly power plants. One of them is the combined wind turbine and solar cell technology to create a more effective solution called a Hybrid power plant. This research proposes a VAWT Helix Turbine Design for Microhybrid Power Plant. The design is according to the wind speed and solar radiation for the Madiun city area. BMKG data shows that the average wind speed is 3 m/s to 7 m/s. Meanwhile, the sun's heat is on average 25°C to 36°C. The wind turbine uses 3 blades of helix type and the solar cell used is Monocrystalline. The design was designed using the AutoCAD program and simulated using Qblade software. The blades are made using 3D Printing Polylactic Acid (PLA) and then printed using a 3D Printer. Simulation results using Qblade show the average value when the wind speed is 3 m/s produces an average power within 11.4 Watt. When the wind speed is 4 m/s, the average power is 33.7 Watt. When the wind speed of 5 m/s produces an average power of 80.2 watts.

Abstract

Natural gas is an essential industrial fluid, and its distribution requires a pipeline system that is safe and leak-free. Leakage in natural gas pipelines remains a major concern, as it reduces public confidence in using gas for household purposes. Therefore, testing is conducted before the pipeline network is operated. One commonly used method to detect leaks is the Pneumatic Test, which evaluates the strength and integrity of pipes and their joints according to standards for polyethylene natural gas pipelines. This test uses compressed air supplied by a compressor, with pressure and temperature measured at the inlet pipe using a pressure gauge. The study found no pressure changes or leakage throughout the test. The calculated holding time required for the pneumatic procedure was 1 hour, 26 minutes, and 8 seconds. Non-Destructive Testing (NDT) results showed that: (a) at 50% of test pressure (approximately 10 bar), the pipe held for 15 minutes with no pressure drop; (b) at 75% (around 15 bar), pressure remained stable for 15 minutes; and (c) at 100% (20 bar), pressure was maintained for 75 minutes without loss. Welding was performed using Nikko Steel electrodes (2 mm × 300 mm, 50–80 A), supported by proper safety gear and tools, and a Riland welding machine with a 400-A capacity.

Abstract

This study aims to analyze the development and trends in rice production in North Sumatra Province during the period 2020–2024 using a descriptive statistical approach. The data used is secondary data from the Central Statistics Agency (BPS) in the form of rice production, harvest area, and productivity. The results of the analysis show that rice production fluctuated but tended to increase, with the highest production in 2024 at 2,204,875.51 tons and the lowest in 2021 at 2,004,142.51 tons. Trend analysis produced a positive slope value of 32,861 tons per year, indicating a long-term upward trend in production. The correlation between harvest area and production shows a strong positive relationship, where an increase in harvest area is consistently followed by an increase in production. Factors affecting production fluctuations include climate change, land area, cropping patterns, and agricultural infrastructure and policy support. Overall, the results of the study confirm that increases in rice production are highly dependent on land management, productivity, and the stability of climatic conditions in the North Sumatra region.

Abstract

The development of science and technology generally brings positive impacts in terms of convenience in various human activities, but on the other hand, it also leads to negative consequences such as an increase in waste. One of the significant wastes produced from construction activities, including building and house construction, is feldspar, which typically comes from leftover ceramic materials. Feldspar is a type of waste that is difficult to decompose naturally and has no economic value, often accumulating and polluting the environment. Therefore, innovation is needed to utilize this waste to create value. This study aims to use feldspar powder as a replacement for fine aggregates in K-200 grade concrete mixtures. The research method involved mixing feldspar powder in specific proportions as a substitute for sand, followed by a series of tests, including compressive strength and flexural tests, to determine the feasibility and performance of the resulting concrete. The results indicate that the use of feldspar powder as a fine aggregate produces a concrete mixture with satisfactory mechanical characteristics, meeting the K-200 concrete standards. These findings not only provide an alternative environmentally friendly material but also offer a solution to reduce ceramic waste, contributing positively to sustainable construction.

Abstract

Mining sequence design is one of the important stages in open pit mining activities that aims to organize the excavation stages so that production activities run effectively, efficiently, and in accordance with the established targets. This research was conducted at PT Putra Perkasa Abadi Site SKS with the aim of designing a mining sequence in January and February 2025. The methods used include analysis of topographic data, geology, pit design, and monthly production targets. The data was processed using mining software to determine the excavation sequence based on elevation, overburden volume, and coal reserves. The design results show that the total planned overburden and coal volume is able to meet the company's production targets by considering slope stability and the efficiency of digging and loading equipment. In addition, the resulting sequence design also takes into account aspects of work safety and field operational conditions, such as mine road access and drainage systems. With a structured design, it is expected that mining activities during this period can run according to schedule, minimize operational obstacles, and support the achievement of production targets and cost efficiency at PT Putra Perkasa Abadi Site SKS.

Abstract

Energy efficiency in water heaters is a crucial factor in ship operational environments due to limited electricity resources that rely on generators. This study aims to design and build an IoT-based water heater monitoring system with an innovative heat storage medium in the form of a mixture of silica sand and paraffin wax to improve thermal efficiency. Although previous studies have developed temperature monitoring and control systems in IoT-based water heaters, this study specifically fills this gap by analyzing the performance of adding silica sand to overcome the low thermal conductivity of paraffin wax. Using the Research and Development (R&D) method, this system was built with an ESP32 microcontroller as the control center, a DS18B20 temperature sensor for accurate measurements, and the Blynk and Google Sheets platforms for real-time monitoring and data recording. Performance testing was conducted by comparing the water heating rate between pure paraffin wax media and the mixed media. The results showed that the monitoring system functioned reliably, and the main finding proved that the addition of silica sand to paraffin wax significantly increased heating efficiency. This was clearly seen from the reduction in time required to raise the water temperature to 40°C, from 2.5 hours to only 1 hour in the second heating cycle. The results of this study indicate that the integration of silica sand and paraffin wax media with IoT technology can increase the efficiency of water heaters and provide an innovative solution for energy-efficient and environmentally friendly temperature control.

Abstract

This research analyzes the implementation of Occupational Safety and Health (K3/OSH) in the automation project of the Vacuum Pan machine at a sugar factory in Indonesia. The Vacuum Pan machine automation project poses high potential hazards due to its involvement with electrical systems, high-pressure pipes, and the installation of electrical and automatic control systems. The research methods used were daily direct observation in the field and interviews with the factory's safety (EHS) personnel, project workers, and interns for one month, from July 7 to August 8, 2025. The results show that K3 planning, such as the availability of HIRADC documents, SOPs, Safety Plans, and K3 facilities (APAR, evacuation routes, safety signs), has been well-implemented and adheres to applicable standards. K3 supervision activities include Safety Inspection (routine twice a week), Safety Patrol (daily and spontaneous), and Safety Talk or Toolbox Meeting (routine every Wednesday). However, the aspect requiring improvement is worker discipline, particularly in the use of Personal Protective Equipment (PPE) and adherence to Standard Operating Procedures (SOPs), which were recorded at compliance frequencies of 65% and 60%, respectively. Workers' response to hazardous situations was also found to be less responsive (50%). In conclusion, while K3 planning and facilities are adequate, the overall K3 implementation needs to be optimized through increased supervision and the establishment of a disciplined culture regarding PPE and SOPs.

Abstract

Rapid and precise handling in determining fault locations is essential to accelerate post-fault recovery and minimize economic losses caused by power outages. Several methods employed to identify fault locations include Single Ended and Double Ended analysis. This paper discusses the Selective Mode Double Ended Fault Locator Method, an enhancement of the IEEE C37.114 Double Ended method. This approach involves selecting maximum fault data values for Near Side (NS) and Far Side (FS) calculations, taking into account the differential or angle difference of the sequence between the two sides. The Double Ended calculation results from the total sample values are used to determine the mode, which serves as the final output of this Fault Locator method. This method is designed to identify faults and their locations with high accuracy and speed. Based on the research findings, the Selective Mode Double Ended (SMDE) method provides more accurate fault locator analysis compared to the Single Ended and Double Ended methods. The accuracy achieved with the Single Ended method is 90.9%, with the Double Ended method reaching 94.9%, and with the Selective Mode Double Ended (SMDE) method achieving 99.9%.

Abstract

This paper was made to explain the results of research on how to obtain the most appropriate citric acid adhesive composition in the manufacture of randu wood fiber composites in order to obtain a strong and suitable composite material. The research was carried out by experimental methods in the laboratory through a series of mechanical tests, namely the bending strength test and the screw grip strength test. The sample specimen is 5 cm × 20 cm × 1 cm for flexural strength testing and 5 cm × 10 cm × 1 cm for screw grip strength test. Composite specimens were made with variations in the composition of citric acid adhesives of 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5%, and 20% by weight of randu wood. The results showed that the composite of randu wood particles with a citric acid matrix had optimal strength at a certain ratio, which was 7.5%. At the same ratio, the test results of the screw grip strength test also provide the highest value. These findings confirm that the exact composition of the adhesive has a significant impact on the final performance of the resulting composite.
