Abstract

The development of composite materials has become one of the efforts to improve energy efficiency, driven by increasing environmental concerns and the depletion of fossil and mineral resources. These issues have encouraged researchers across various countries to seek accurate and effective solutions, particularly in reducing the use of metallic materials in a sustainable manner. Research on natural fiber composites presents significant potential as an alternative sustainable material; however, technical challenges, economic value, and real-world application must be overcome in order to compete with conventional materials. Efforts to develop more environmentally friendly fiber processing methods are essential to maintain environmental stability during production and usage. Improving mechanical properties through variations and combinations of fibers and matrices tailored to specific functions or mechanical needs is also critical. Based on the research and analyses conducted, composite materials demonstrate good durability and mechanical strength using various components such as carbon or aramid fibers, combined with different types of matrices like polyester resin, epoxy, binders, and polypropylene. Each type of matrix significantly influences the resulting mechanical strength. With the continuous advancement of research, natural fibers offer great potential due to their abundant availability and eco-friendliness compared to carbon or aramid fibers, even though their mechanical strength is not yet on par

Abstract

This study aims to determine the value of load variations on kinetic energy and mechanical energy. The method used in this study is the experimental method. The surface and length of the inclined plane are kept constant, with an adjustable angle of inclination. Determination of kinetic energy and mechanical energy is done by observing the slide of the object from the top of the inclined plane which is documented in video form. Based on the results of the study, it can be concluded that the mass of an object affects kinetic energy and potential energy. Based on the results of the trial, the greater the mass of the object, the greater the value of kinetic energy and potential energy. Kinetic energy is also related to the law of conservation of mechanical energy, which states that the total amount of kinetic energy and mechanical potential energy in a closed system remains constant, as long as there are only conservative forces acting on it.

Abstract

Motorcycles are the dominant means of transportation in Indonesia. The land transportation population in Indonesia in 2021 was 141,992,573. Motorized vehicles are predominantly motorcycles, with 120,042,298 users. According to the 2021 report by the Indonesian Statistics Agency (BPS), the number of motorcycles continues to increase by an average of 4.62% per year. Aluminum rims are the most widely used type today. In addition to their more attractive design, aluminum rims are also corrosion-free and much lighter than steel rims, making it easier to achieve acceleration and top speed. Larger rims allow for wider tires. This can improve vehicle traction and stability, especially when driving at high speeds or on uneven roads. Wheel traction is one of the vehicle's capabilities to push a load. Traction is a large force that determines the power of the engine, wheels, and wheel load to turn on between the wheels and the road. Traction force analysis needs to be done to get an efficient traction force. This study uses an experimental method with a motorcycle that turns on so that the rear wheel rotates and a traction force occurs between the tire surface and the road surface. This study uses rim sizes of 17x1.60, 17x1.85 and 17x2.15. The results of the study show that differences in rim sizes affect the traction force on the rear wheels, where the highest traction force occurs on the rim size of 17 x 2.15 inches of 2399 Newtons and the lowest traction force occurs on the rim ring of 17 x 1.60 inches of 1438.7 Newtons.

Abstract

This paper discusses the design and implementation of ultraviolet light control in corn fodder. The problem with corn fodder is that temperature and humidity and inappropriate lighting can trigger the growth of mold. The ultraviolet light illumination control system method uses a fuzzy logic method to control ultraviolet light illumination. So it affects temperature and humidity, as well as growth of corn fodder. The results of the comparison of the Mamdani fuzzy control system using Matlab and Arduino applications to control corn fodder illumination obtained defuzification values (0.5, 2.5, 6.5). The implementation of the Mamdani fuzzy logic control system affects the light, temperature and humidity, as well as the height and weight of the corn fodder with a definition error of 0.5%. Lighting 5 hours/day on a full spectrum grow light (380nm-730nm) with a light intensity of 2053lux, for 14 days produces a temperature of 27˚C and humidity of 93%, fodder height reaches 28cm with a total weight of 124 grams. Meanwhile, the grow light spectrum (450nm-460nm) with a light intensity of 1462.5 lux produces a temperature of 28˚C and humidity of 85%, the height of the fodder reaches 26.5cm with a total weight of 120 grams. Optimum lighting results were obtained in 5 hours of light with a full spectrum grow light lamp with a light intensity of 2053lux, for 14 days resulting in a temperature of 27˚C and humidity of 93%, the height of the fodder reached 28cm with a total weight of 124 grams.

Abstract

The increasing electricity demand in Indonesia’s small and medium enterprise (SME) sector has encouraged the adoption of renewable energy technologies to improve energy efficiency and reduce operational costs. This study aims to evaluate the technical and economic feasibility of integrating a grid-connected rooftop photovoltaic (PV) system at Diva Bakery, a food-processing SME located in Banyuwangi, East Java, Indonesia. The system was designed using a rooftop maximum capacity scenario and simulated using PVsyst software, while economic feasibility was assessed through discounted cash flow analysis. The proposed system has an installed capacity of 4.95 kWp, consisting of 9 monocrystalline PV modules rated at 550 Wp and a 4 kW grid-tied inverter. Simulation results indicate that the system can generate 8,288.4 kWh/year, with a specific yield of 1,674 kWh/kWp/year and a performance ratio of 80.51%, demonstrating good technical performance under tropical climatic conditions. The largest system loss was attributed to temperature effects, highlighting the importance of proper ventilation and installation design. Economic analysis shows an annual electricity cost saving of IDR 14.09 million, with a Net Present Value (NPV) of IDR 58.4 million, an Internal Rate of Return (IRR) of 18.7%, a discounted payback period of 5.4 years, and a Levelized Cost of Energy (LCOE) of IDR 986/kWh, which is lower than the applicable PLN electricity tariff. In addition, the system is estimated to reduce carbon emissions by approximately 6.08 tons CO₂/year. The results confirm that rooftop PV implementation in food-processing SMEs is technically feasible, economically attractive, and environmentally beneficial, making it a promising strategy to enhance SME competitiveness and support Indonesia’s clean energy transition.

Abstract

This study presents a field-based performance analysis of turbofan gas turbine engines operating in Indonesia’s commercial aviation sector under tropical environmental conditions. The research focuses on how ambient temperature, humidity, operational frequency, and short-haul flight patterns influence actual engine performance relative to ideal thermodynamic expectations. A mixed-method design was applied by combining literature-based Brayton-cycle modeling with empirical operational data from CFM56 and V2500 engine families. Data sources included engine logbooks, maintenance records, operational observations, and ambient condition monitoring at selected Indonesian airports. The analysis shows that actual specific fuel consumption (SFC) was consistently 5-10% higher than theoretical estimates under high-temperature operating conditions, particularly above 30 °C. Field observations also indicated reduced thrust margins, increased exhaust gas temperature (EGT), and decreasing propulsive efficiency during high-load flight phases, especially takeoff and climb. These deviations confirm that tropical operating conditions and repetitive short-sector utilization accelerate performance deterioration beyond ideal-cycle assumptions. The main scientific contribution of this study is the demonstration that Brayton-cycle-based turbofan performance prediction for Indonesian commercial aviation requires correction for local environmental and operational factors. The findings support the use of climate-adaptive performance assessment and condition-based maintenance strategies to improve engine efficiency, reliability, and operational safety.

Abstract

Gas turbine engine maintenance is a critical factor in ensuring reliability, safety, and cost effective operation in aviation and power generation systems. This review examines the development of maintenance strategies from conventional time based maintenance (TBM) to condition based maintenance (CBM), predictive maintenance, and risk based decision frameworks. The review was conducted through a structured analysis of published journal articles, technical reports, and case based studies concerning gas turbine engine performance, maintenance scheduling, and health monitoring applications. The selected literature was evaluated based on maintenance objectives, data requirements, implementation complexity, and reported operational outcomes such as cost efficiency, downtime reduction, and failure prediction capability. The findings indicate that TBM remains useful for standardized maintenance planning but is limited in responding to actual engine condition. In contrast, CBM and predictive maintenance provide improved responsiveness through sensor based monitoring, prognostic health management, and machine learning assisted anomaly detection. Risk based approaches, including Partially Observable Markov Decision Process (POMDP) models, offer stronger support for maintenance optimization under uncertainty by balancing reliability, cost, and operational risk. However, the review also identifies important limitations, including inconsistency in reported performance metrics across studies, high infrastructure requirements, and challenges in integrating digital tools with existing maintenance and regulatory frameworks. Overall, the review highlights that advanced maintenance strategies have strong potential to improve the efficiency and reliability of gas turbine engine operations, particularly when supported by digital monitoring, data analytics, and structured decision making models. Future implementation in aeronautical applications should therefore emphasize scalable data integration, engineering interpretability, and alignment with airworthiness requirements.
