Abstract

The Community Service (CS) program took place in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, approximately 100 km southwest of Malang City. The target group for this program includes small and medium enterprises (SMEs) engaged in koi fish spawning. Our partners face several challenges, primarily the reliance on aeration pumps powered by the national electricity grid (PLN) to supply oxygen to the ponds. The program aimed to install a 100 Wp solar panel system to generate clean energy for a low-voltage aeration pump, helping to maintain optimal oxygen levels in the pond and supporting healthy fish growth. The program successfully implemented this solar-powered aerator pump system in the pond area, providing an innovative, sustainable solution that empowers the community by integrating science and technology into fisheries. It is hoped that this program will inspire other fish farmers in Tulungagung and surrounding areas to adopt similar sustainable practices.

Abstract

Limited supplies of fossil fuels such as gasoline, diesel and LPG resulting in vehicles that use internal combustion would be abandoned and replaced by electric vehicles. There have been many coverages that have reviewed the advantages of electric vehicles, where the advantages of electric vehicles include simple mechanical components, relatively low pollution, low noise levels, and could become a solution for future vehicles for an environmentally friendly life. This study aims to design and build a motorcycle prototype, a work which includes the design and manufacture of a BMX type motorcycle frame powered by a 2000 watt BLDC motor power, and testing the performance of the prototype using dynotest and compared to conventional motorcycles to compare the performance characteristics of both motorcycle. The frame is designed using Solidworks, then manufactured by cutting, bending, drilling, welding, and painting process. Mechanical components include frames that use mild steel pipes with diameter of 1.5 inches and thickness of 1.2 mm. Other mechanical components use components available on the market, such as headsets, front forks, disc brakes, hydraulic caliper brakes, and wheel assemblies. The electrical components used are 48V 2000-watt QS Motor, 60V 15 Ah Lithium battery, Yuyangking 80A controller and electric gas throttle with voltage indicator. The results of the dynotest show that the maximum torque reaches 204 NM (roller) which is achieved at 976 rpm. The maximum speed reaches 69.7 Km/hour. The range of the single-charged battery could cover a distance of 30 km. The characteristic of 2000 Watt E-BMX is very powerful at low revs and stable at high revs, shown by achieving maximum torque at low RPM. To save battery life, it is necessary to limit the remaining voltage, which is done at 55 Volts, so that the battery do not completely run out. It could be concluded that electric motorcycle developed in this study is suitable for use in urban areas (paved tracks or light off-road) with determined mileage and the path travelled, and battery management is needed so the battery does not run out in the middle of a trip.

Abstract

Fiber-reinforced composites can be classified into two parts, namely short fiber composites and long fiber composites. Long fibers are generally stronger than short fibers. Long fiber (continuous fiber) is more efficient in laying than short fiber but short fiber is easier to lay than long fiber. Fiber length affects the processability of the fiber composite. Judging from the theory, long fibers can transfer the load and stress from the stress point to the other fiber. In this research, we simulated the effects of volume fraction and fiber orientation in glass fiber-reinforced polyester composites on bending strength to examine the effect of each parameter on the mechanical properties of glass fiber composites. The mechanical properties of the composite were tested using the three-point bending and tensile testing methods. The study expects to find variations in mechanical properties with changes in the glass fiber volume fraction and fiber orientation. In this study, it is planned to function in a relevant environment, the components in this study must be able to operate properly and have been well integrated with prototype manufacturing that has been tested as a test tool function. Notably, the pinnacle of the bending test, measuring 170.41 MPa, was achieved at the specific combination of a 0.5 Fiber Volume Fraction and the 0-90o fiber orientation.

Abstract

Timely distribution of Palm Kernel (PK) is critical for maintaining Free Fatty Acid (FFA) levels and supply chain stability, yet logistical inefficiencies persist in the Indonesian palm oil sector. This study empirically investigates the determinants of shipment delays within the trucking logistics framework of a major Palm Oil Mill in Central Kalimantan from 2022 to 2024. Utilizing a mixed-methods approach, the research integrates historical shipment data (N=119), field observations, and linear regression analysis to evaluate six potential delay factors. The findings reveal a 23.5% delay rate over the three-year period, with 'Long Holidays' (religious festivals) and 'Weather/Road Conditions' identified as the most significant predictors of lateness, particularly in 2024 where holidays showed a dominant regression coefficient (β=0.962). Unlike previous studies focusing solely on infrastructure, this research highlights a shift toward seasonal operational constraints and transporter performance. The study implies that technical fleet upgrades are insufficient without adaptive scheduling strategies. Consequently, implementing predictive logistics planning around seasonal events and real-time infrastructure monitoring is recommended to mitigate delays, offering a practical framework for enhancing supply chain resilience in the tropical agricultural industry.

Abstract

The fused deposition modeling (FDM) process is an additive manufacturing technique that fabricates 3D objects through layer-by-layer deposition of molten material. This study aims to determine the optimum process parameters for fabricating onyx-glass fiber composites with maximum impact strength. Onyx, a nylon-based filament filled with micro-carbon fibers, was selected because it is stronger and stiffer than conventional ABS and can be reinforced with continuous fibers. This optimization is important for lightweight structural components, such as electric-vehicle gears, where durability and resistance to dynamic loads are required. The Taguchi method with an L9 orthogonal array was applied, with three parameters investigated: filling density, number of wall layers, and number of glass fiber layers. Impact testing was conducted in accordance with ASTM D6110-10 using a Charpy impact tester. ANOVA results indicated that the number of glass fiber layers was the only factor with a statistically significant effect on impact strength at the 95% confidence level (P = 0.043), while the number of wall layers was statistically insignificant (P = 0.468). Filling density showed a marginal contribution to impact strength (P = 0.073). The optimum combination within the investigated parameter range was identified as 30% filling density, two wall layers, and 18 glass fiber layers, producing a maximum observed impact strength of 0.375 J/mm2.

Abstract

Using Aluminum 7075 at a high temperature of 50 degrees Celsius, this study examines the effect of various blank geometry angles on the mechanical properties of strain and stress during the deep drawing process. This study systematically examines the impact of different blank geometry angles on the deformation behavior, strain distribution, and stress concentration during the deep drawing process of Aluminum 7075 sheet using a numerical simulation approach. To describe the behavior of the material against the effect of the angle on the pressure in the simulation taking into account realistic parameters, the main point is the result of the pressure treatment of the predetermined angle on the results of the strains and stresses created. The obtained results, which include strain distribution, stress concentration, and overall mechanical reaction, provide important information for the choice of the best blank geometry angle in deep drawing of Aluminum 7075 at high temperatures. This research contributes to the advancement of process optimization in the metal forming industry, providing a solid foundation for improving efficiency and quality in deep drawing operations involving high-strength aluminum alloys.

Abstract

In this study, fatigue testing of fiber metal composites was carried out to determine the rate of crack propagation so that the age of the fiber metal composite specimen was known. The independent variable in this research is the angular orientation of the carbon fiber and the surface roughness of the aluminium with the dependent variable response is the bridge crack rate. The manufacture of fiber metal laminates specimens uses the Vacuum Assist Resin Infusion (VARI) method, which uses a vacuum pump as a means to flow the resin from the reservoir to the mold. Fatigue testing is performed using the stress amplitude method. That is, the value of the load when the tensile test is one third of the tensile strength. After the fatigue test was carried out, the results were obtained on specimens with an angular orientation of 0/90° fibers, the crack propagation rate slowed down with a cycle value of 90,000 in specimens with a surface roughness value of 2.128 µm then decreased cycles on specimens with a value of 2.887 µm, namely 11,000 cycles.

Abstract

The inconsistency of the wind flow considered as one of the factors which tend to decrease the performance of the wind turbine. This paper proposes a further analysis of the initial rotation characteristic of a hybrid Savonius-Darrieus wind turbine. The addition of the Darrieus blade intends to increase the aerodynamic stability of the overlapping Savonius turbine. This study implements 2D Computational Fluid Dynamics (CFD) transient analysis using the six Degrees of Freedom (DOF) methods in 0°, 30°, 60°, and 90° Darrieus blade position along with 2, 4, and 6 m/s wind speed variations. The results of the aerodynamic analysis show that the location of the Darrieus 30° turbine provides the greatest initial repulsion, especially when the turbine rotation is above 90°, the position of the Darrieus blade can provide additional impulse force when the Savonius turbine tends to be passive. This effect occurs more significant at higher wind speeds. Savonius with 3-blade modification has a more stable level of force distribution than the 2-blade modification, although the value is smaller. This shows that the 3-blade Savonius provide a higher stability of angular velocity development.
