Abstract

The development of automotive technology is very fast, we can find this in today's vehicles that use a lot of very sophisticated technology, namely in terms of engines, electricity, and its newest features, especially on two-wheeled vehicles. Therefore, the user community is required to be more selective in choosing a vehicle both in terms of quality and quantity. Including in the selection of spare parts on vehicle engines must use good quality, this is useful as a motorbike power booster, especially in the ignition system, namely spark plugs as a vital tool that sprinkles sparks in the combustion chamber. Recently, many spark plugs have been found that are not good enough so that the power generated by the vehicle is reduced. The purpose of this test is as a Comparative Test of the Endurance of Various Motorcycle Spark Plugs by Using a Spark Plug Tester so that it can be seen that the spark plug is suitable or not used in the vehicle which aims to get maximum performance.

Abstract

Noise on a motorcycle is unwanted sound because it does not fit the context of space and time thus affecting ride comfort . Noise caused by the vibrating object or objects collide . Which became the main object causes of noise in the Cylinder Head Honda cb 150 R is due to the large gap camshaft causing collision between the camshaft with holder. This research was conducted entirely in the workshop by examining the influence of several variations of the gap camshaft to noise generated in the cylinder head . Variations slit used was 0,75 mm , 0,85 mm , 0,95 mm , 1,05 mm, and 1,15 mm . The results showed that the variation of the gap camshaft significant effect on the noise generated , namely : a gap of 0,75 mm camshaft generate noise by 78,12 dB , 0,85 mm gap camshaft generate noise with a value of 78,37 dB , 0,95 mm gap camshaft generate noise 78,93 dB , 1,05 mm gap camshaft generate noise levels at 79,95 dB, and 1,15 mm gap camshafts produce 80,23 dB. Based on the results of the research with camshaft gap variation can be concluded that the lowest noise level generated by the camshaft gap of 0,75 mm .

Abstract

Bahan Bakar Gas (BBG) merupakan gas alam dengan komponen utamanya methana, jenis bahan bakar ini banyak ditemukan di Indonesia. Keuntungan dari penggunaan bahan bakar gas adalah lebih murah dari BBM, lebih ringan dari udara, usia mesin lebih lama, perawatan lebih murah dan tidak mencemari lingkungan. Salah satu penggunaan dari BBG adalah pada kenderaan roda dua. Metode yang digunakan dalam penelitian ini adalah dengan merancang sebuah alat yang digunakan untuk melakukan perubahan sehingga bisa memanfaatkan bahan bakar yang berbeda yang disebut dengan alat konversi (Converter). Pengujian dilakukan pada mesin sepeda motor injeksi berbahan bakar gas LPG 3 kg menggunakan alat uji dynotest dengan variasi putaran mesin. Hasil pengujian torsi maksimumnya adalah 8,55 Nm pada putaran mesin 5500 rpm dan daya maksimumnya 7 Hp diputaran mesin 6000 rpm. Untuk pengujian suhu pada putaran stasioner adalah 770c dan hasil uji sistim pembakaran pada busi dengan jarak tempuh 244 km warna busi abu-abu kemerahan hal menunjukan hasil pembakaran yang sempurna. Pada pengujiaan pengukuran emisi gas buang menggunakan alat Gas Analyzer Stargas mod 898 kadar CO 0,06 %, kadar CO2 2,1%, kadar O2 20,53% dan kadar HC 3234 ppm. Berdasarkan hasil pengujian ini maka bahan bakar bakar gas LPG dapat digunakan untuk motor injeksi sebagai bahan bahan bakar alternative dan ramah lingkungan.

Abstract

This article presents an asymmetric parallel manipulator with 2(RRPaRR)-PRRR kinematic chains. This manipulator aims to operate as a lower-mobility parallel manipulator with the pure translational motion of its platform. Therefore, a series of analyses are performed to fulfill this intention. First, the mobility analysis is performed by applying the Grübler-Kutzbach equation and the screw theory. Then, the kinematic, singularity, and workspace analysis are applied to analyze this PM. As  a result, the application of the screw theory for the configuration of its kinematic chains shows its mobility in a pure translational motion in space. Then, this manipulator has a closed-form solution for its direct kinematic problem expressed in a quadratic equation. By applying singularity and workspace analysis via visualization, the singularity-free workspace along the z-axis of its workspace can be identified. This can later be used as a useful workspace. Overall, the presented manipulator can be applied to a translational parallel manipulator

Abstract

In the conventional machining process, production costs are essential to know to determine the cost of making a product in any industrial manufacturing such as the SMK N 2 PEKANBARU machining workshop. Machining production costs are calculated based on machining time per product and machining operation costs. In calculating conventional machining costs, the VBA Excel macro is an application that can be used to calculate production costs. The Ø65mm × z24 umbrella gear product which is the research case study is a product that is machined by two conventional machining processes, namely lathe machining and milling machining. From the results of the research, the cost of conventional lathe machining, namely making gear wheels, is IDR 47,841/product, and the conventional milling process, namely making Z24 gears, is IDR 40,002/product, while the machining cost for lathe mastercam simulation is IDR 33,187/product and the machining cost for milling mastercam simulation is IDR 20,340/product. Machining costs are the product of operating costs per minute (cm) and machining time (tm). So, from the results of calculating machining and production costs, it is known that the product manufacturing costs or production costs for Ø65mm × Z24 umbrella gears are in the range of IDR 111,827 - IDR 146,143/product.

Abstract

Urban areas are increasingly facing the problem of noise pollution, which can significantly affect their residents' quality of life, health, and productivity. Noise caused by road traffic is one of the main contributors to this issue, particularly in cities with high traffic volumes. Despite its impact, the relationship between traffic patterns and noise levels at different times of the day remains underexplored. This study aims to investigate the variation in vehicle noise levels at different times of the day on Jalan Jenderal Sudirman in Pekanbaru City, Indonesia. The primary objective is to assess how vehicles' volume and speed contribute to noise pollution changes during peak and off-peak hours. The study was conducted by measuring the noise levels at three distinct time intervals: 07:00-09:00 GMT (morning), 11:00-13:00 GMT (daytime), and 15:00-18:00 GMT (afternoon/evening). These periods were selected to reflect the variation in traffic density and activity during the day. The data were analyzed using the ANOVA test to determine whether there were any significant differences in the noise levels across the different time intervals. The results showed that the average noise levels were similar during all three periods, with no statistically significant differences detected. The findings suggest that traffic volume and vehicle speed consistently impact noise pollution throughout the day. This study highlights the importance of managing traffic flow and vehicle speed to mitigate noise pollution in urban environments. The results also provide valuable insights for local authorities to develop policies to reduce noise pollution and improve the overall quality of life for residents in Pekanbaru.
