Abstract

With the rapid development of science and technology, people need to be innovative and contemporary. New structures have been widely developed using composite materials made from natural fibers. This research aims to determine the effect of the volume fraction of epoxy matrix pandan tectorius leaf fibers with an epoxy matrix on tensile and bending strength to determine the best results of speciments. Pandan tectorius leaf fiber composites with epoxy resin matrix adopts hand-laying technology, and pandan leaf fiber composites are used for two tires. In this research, the volume ratio of pandan leaf fiber and epoxy resin matrix was found to be 40:60, 45:55, 50:50, 55:45 and 60:40. In the tensile test, the highest value in the average tensile strength of the epoxy-based pandan fiber material was 15.8 N/mm2, and the lowest value was observed when the fiber and matrix volume ratio (40:60) was changed. It occurs when the fiber and matrix volume ratio changes (50 : 50) is 12.2 N/mm2. Meanwhile, in the bending test, the highest average value of bending strength was for the variation of fiber and matrix volume fraction (60: 40), and for the lowest value for the variation of fiber and matrix volume fraction (40: 60), it was equal to 17.36 N/mm2.

Abstract

Rice straw fiber is considered as agricultural residue that has not been widely used other than as animal feed. In addition, the development of composite material technology that uses natural fibers provides interesting mechanical properties to be developed. This paper aims to investigate the effect of different concentrations of fiber usage on bending and tensile strength. The comparison of concentrations of fiber usage are 35% , 40% , 70% dan 80%. The straw fiber was decreased the moisture content using a microwave and  the treatment with NaOH for removed the hemicellulose and lignin in the fibers. The manufacture of this biocomposite uses a matrix of Urea Formaldehyde with a hand lay up technique. The results of the mechanics test(bending and tensile strengths) show that the strength value obtained on the straw fiber variation, namely the highest average value of the Tensile test is 4.82 MPa at a ratio of 40 : 60, while the lowest is 2.88 MPa at a comparison 35 : 65 and and the highest average value of the bending test is at a ratio of 80:20 (6.64 N/mm2), while the lowest is 40:60 (2.45 N/mm2).

Abstract

In the motorcycle ignition system, spark plugs play an important role in sparking the sparks needed to burn fuel with compressed air. The purpose of this research is to determine the ratio of torque, power, fuel consumption in 4-stroke gasoline engines produced from standard, two legged, platinum, and iridium spark plugs using pertalite, pertamax and pertamax turbo fuel. This test uses a 4 stroke 150 CC gasoline motorcycle. Motorcycle engine performance testing is done using a dynotest. The results obtained were the peak power in the Pertamax fuel test using iridium spark plugs of 14.3 Hp at 8000 RPM engine speed, 0.71% higher than Pertamax fuel using standard manufacturer spark plugs. Then the highest torque from all test data is on the Pertamax fuel test using iridium spark plugs of 13.43 Nm running the 7000 RPM engine which is 0.22% higher than Pertamax fuel using standard manufacturer spark plugs. Meanwhile, the lowest or most efficient fuel consumption was in testing the Pertamax turbo fuel using an iridium spark plug of 0.059 kg/kWh running a 6000 RPM engine, 1.69% more efficient compared to Pertamax turbo fuel using a standard manufacturer's spark plug.

Abstract

This research explores the application of computer vision using YOLOv5 Medium for automatic object detection in unmanned rail inspection systems. The proposed technique utilizes image processing to analysing pixel values and detect optical motion vehicles. This detection triggers control system responses, such as activating the inspection train's motor upon vehicle identification. The study demonstrates the effectiveness of YOLOv5 Medium in achieving high accuracy rates. Evaluations at various distances yielded promising results: 97.98% at 3 meters, 100% at 5 meters, 99.49% at 7 meters, and a perfect 100% at 9 meters. These findings suggest optimal system performance at a distance of 9 meters. Overall detection performance across all test distances remained consistently high, with sequential rates of 0.96, 0.97, 0.95, and 0.96. This research emphasizes the crucial role of several factors in maintaining system accuracy and performance. These include the efficacy of the colour segmentation algorithm, ambient lighting conditions, and camera resolution. Furthermore, the importance of extensive testing with a diverse dataset is highlighted to ensure the system's robustness and adaptability to various real-world scenarios.

Abstract

A nation's transport system is one of the many aspects that affect its economic growth. One mode of transportation that is frequently used by society at large is the train. With advancement. Because technology is developing so quickly, humans are needed to carry out new inventions. More contemporary, the innovation being created frequently is the application of composite materials made of raw natural fibres. One of the uses of coconut fiber is as a composite material used as a coating for the train carbody. This study will test composite materials on coconut fiber using a polyester resin matrix with a random fiber arrangement using the hand lay-up method and mesh variations of coconut fiber 50, 100, 150, and 200 at volume fraction 40%.

Abstract

This study aims to analyze the effect of firing point variations on the performance of the S195 type diesel engine using a mixture of Dexlite fuel and cooking oil. The firing point variations used were 17°, 18°, and 19° before TDC, with the fuel mixture containing 30% cooking oil. Tests were conducted to measure thermal efficiency, specific fuel consumption (SFC), and engine output power. The results showed that proper firing point settings can increase thermal efficiency and decrease SFC, especially at an angle of 18°, where the highest thermal efficiency was 24.80% and the lowest SFC was 0.342 kg/kWh. In addition, the use of this mixed fuel was able to provide more perfect combustion than pure Dexlite fuel. The conclusion of this study suggests the need for good engine maintenance and proper injection timing to improve the performance of diesel engines based on mixed fuel, as well as an effort to utilize cooking oil as a renewable energy source.
