Abstract

Current leakage in parallel gap single-sided double spot welding tools occurs if the insulation to the mass-body, either from the work table or the drive system, can reduce the current concentration and result in double-sided welding being relatively difficult to carry out or the weld results being poor. Therefore in this research, an experiment was carried out to test the machine how big the effect of leakage current is on the quality of welded joints by comparing the strength of the joint between a system without insulation and a system using insulation using the independent sample t-test statistical method with a confidence level of 95%. The results of the study show that overall the max load for CT 3 to 10 is a mean difference between without and with insulation, although it is not very significant, this is because the shear test data from the group without insulation has quite a high deviation. High deviations also occur in the upper yield data, the strongest conclusion is that providing insulation (or preventing leakage current) provides a more consistent welding result as seen from the results of the shear test data. Only CT 3 has a significant impact on both max load and upper yield.

Abstract

Penelitian ini bertujuan untuk merancang dan membuat stabilizer perahu dari material komposit berbahan serat jerami padi dan resin polyester. Latar belakang penelitian ini adalah penggunaan stabilizer perahu tradisional yang masih menggunakan bahan bambu dan busa yang kurang efisien serta masalah limbah jerami padi yang belum dimanfaatkan secara optimal. Metode penelitian melibatkan pembuatan spesimen dengan berbagai fraksi volume serat dan resin, kemudian dilakukan uji tarik dan uji bending untuk menentukan kekuatan komposit yang dihasilkan. Hasil pengujian menunjukkan bahwa fraksi volume serat 5% dan resin 95% menghasilkan kekuatan tarik dan bending tertinggi dengan nilai masing-masing 20,75 N/mm² dan 192,94 N/mm². Berdasarkan hasil analisis simulasi menggunakan Solidworks, desain stabilizer dengan komposisi serat 15% dan resin 85% dipilih untuk digunakan dalam aplikasi lapangan. Stabilizer yang dihasilkan menunjukkan kinerja yang baik dalam uji lapangan, dengan nilai faktor keamanan sebesar 1.087,56. Penelitian ini menyimpulkan bahwa komposit serat jerami padi dapat menjadi alternatif bahan yang kuat, ringan, dan ekonomis untuk stabilizer perahu.

Abstract

Indramayu is the largest rice barn area in Java, so it contributes waste from the rice production process, but the waste processing process is less productive or there are very few enthusiasts. So there is a very big opportunity by utilizing waste which is more useful, namely by processing it into fish pellets which have a high price value compared to other processing methods. The design of the rice husk grinding machine uses a type 32 disk mill knife and a type 32 fish pellet printer that will print 3 mm pellets with a machine frame dimension of 849 x 597 x 918. The frame of this machine uses 40 x 40 x 1.35 mm hollow iron. The specifications of this fish machine consist of three main components, namely a husk refiner, a pellet dough mixer, and a fish pellet molder driven by a combustion engine with the motor power and speed used, namely a refiner power of 1.82 HP with a speed of 3600 rpm, a mixer power of 1.86 HP with a speed of 771.42 rpm, a molding power of 0.56 HP with a speed of 771.42 rpm. So the total power used for this machine is 5.5 HP or 4.1 kw. So it can be seen that the motor power is 5.5 HP < 7 HP, so a 7 HP drive motor can be used.

Abstract

Separating rice and bran, moving rice to storage, and other processes related to moving grain or rice. In the modern rice milling industry, the process of transferring grain material already uses a pneumatic conveying system; a vacuum blower system for transferring grain is needed when milling grain to become rice. The research method used to obtain the shape of a vacuum blower with strong inlet suction power and outlet thrust is carried out by Computational Fluid Dynamics simulation and testing several types and variations in the number of blades. Simulation of forward curved blade type impellers, backward curved blade, and straight radial blade with variations in the number of 8, 10, and 12 blades. From the impeller simulation, it was obtained that the straight radial blade with 8 blades was the best. The best impeller types were made using the manual method. Measurement results were on the straight radial blade type impeller with 8 blades, with a motor speed of 1,000 rpm; the results of measuring air speed at the inlet were 34.95 m/s and at the outlet 23.08 m/s. In addition, the difference in the results between in simulation and the experiment is due to the fabrication process and air leaks.

Abstract

Proses pembuatan bumbu Soto Mie Bogor secara manual membutuhkan waktu yang lama, antara 1 hingga 2 jam untuk mengolah 3 kg bumbu, dan mengandalkan tenaga manusia yang besar. Hal ini mengakibatkan pengadukan yang tidak merata serta mempengaruhi kualitas bumbu. Penelitian ini bertujuan untuk merancang dan menguji mesin penggiling dan pengaduk bumbu Soto Mie Bogor dengan kapasitas 10 kg, yang terdiri dari 8 kg bumbu dan 2 kg minyak, guna meningkatkan efisiensi produksi UMKM. Mesin ini menggabungkan fungsi penggilingan dan pengadukan dalam satu unit yang digerakkan oleh motor listrik 0,75 kW dengan sistem transmisi gearbox rasio 1:40. Desain mesin menggunakan perangkat lunak SolidWorks 2021. Hasil pengujian menunjukkan bahwa mesin ini dapat mengurangi waktu pengolahan bumbu menjadi sekitar 1 jam, jauh lebih efisien dibandingkan dengan metode manual yang memakan waktu 3–4 jam. Mesin ini diperkirakan mengonsumsi sekitar 0,75 kWh per hari, dengan biaya listrik bulanan sekitar Rp31.000 jika beroperasi selama satu jam setiap hari. Implementasi mesin ini diharapkan dapat mengurangi kesalahan manusia, meningkatkan kapasitas produksi, dan mengoptimalkan waktu operasional UMKM Soto Mie Bogor.
