Abstract

The strength of the welded joint is greatly influenced by one of the welding parameters, namely the amount of welding current. Determination of the amount of current in metal joining using arc welding. To get a good connection quality, it is necessary to determine the right current. The purpose of this study was to determine the tensile strength and hardness values ??of ASTM A36 low carbon steel after being welded using E 7018 electrodes with several current variations. This research is an experimental study that analyzes the tensile strength and hardness values ??of welding ASTM A36 low carbon steel using variations of three welding currents, namely 120A, 125A and 130A. The specimens used came from a material in the form of low carbon steel ASTM A36 with a thickness of 10 mm which had been welded using an E 7018 electrode. The results of the research that had been carried out showed that the average value of the tensile strength using a current of 120A was 510.49 (N/ mm²). The 125A current is 437.15 (N/mm²), and the 130A current is 258.72 (N/mm²). While the average hardness value of the specimen using a current of 120A is 78.83 HRB, at a current of 125A it is 89.81 HRB, and a current of 130A is 78.90 HRB. The results of welding with the E 7018 electrode have an ideal tensile strength with a welding current of 120A, while the highest hardness value is found at a current of 125A.

Abstract

Food security is a problem that the world will face in the future. One solution to address the issue of food security globally is in the fisheries sector. Indonesia is considered a solution as it is the second largest fish producer in the world, as stated by the FAO in The State of World Fisheries and Aquaculture 2022 report. However, in order to increase fish production, aquaculture needs to be conducted to maintain the stability of fisheries in Indonesia. To facilitate this process, an automatic fish feeder device is required. This device needs to undergo research, specifically in the field of buckling analysis. Buckling is a failure phenomenon that occurs due to compressive pressure on a structure, causing a change in its shape in the form of lateral deflection to another equilibrium form. In this analysis, calculations are performed for critical loads, deformation, and equivalent stress. The applied load on the frame is 100 kg or 981 N. The obtained critical load for frame type 1 with a cross-sectional area of 40 mm x 40 mm x 0.5 mm is 13.879,923 N, while for frame type 2 with a cross-sectional area of 40 mm x 25 mm x 0.5 mm, the critical load is 12.621,791 N. The maximum deformation for frame 1 is 0.25013 mm, and the minimum deformation is 0 mm. For frame 2, the maximum deformation is 0.53323 mm, and the minimum deformation is 0 mm. The maximum equivalent stress for frame 1 is 180.38 MPa, and the minimum equivalent stress is 0.0046383 MPa. The maximum equivalent stress for frame 2 is 99,735 MPa, and the minimum equivalent stress is 0.0016464 MPa.

Abstract

Diabetic Retinopathy (DR) is a disease whose main cause is complications of diabetes mellitus. High levels of sugar in the blood (glucose) are caused by the pancreas' inability to produce insulin. Prevention of diabetic retinopathy and blindness by carrying out examinations at an early stage and doing them regularly. Currently, doctors still carry out examinations manually so they are prone to errors in examinations. This research aims to build an application to diagnose Diabetic Retinopathy in order to facilitate the work of the medical team and doctors at the eye clinic. In the application creation process, MATLAB is used, while feature extraction uses GLCM and for classification, SVM is used. The results of the research are that doctors and medical teams are helped in carrying out manual patient diagnoses and reduce the occurrence of human error.

Abstract

Waste-oil management is a critical environmental issue, as used oil is classified as hazardous and toxic (B3) waste whose volume keeps rising with the growth of motor vehicles in Indonesia. Meanwhile, coffee farmers in Dusun Punik, Batu Lanteh District, Sumbawa Regency still face difficulties in post-harvest coffee bean drying due to their dependence on sunlight and the increasingly limited supply of firewood. This study aims to design, fabricate, and test a used-oil-fueled burner stove as a heat source for a coffee bean dryer, offering a productive use for used-oil waste. The method includes a literature review, a field study, design using Autodesk Inventor, fabrication at the Mechanical Engineering Workshop of Universitas Teknologi Sumbawa, and performance testing with three test repetitions to measure drying-chamber temperature, time to reach the target temperature, and fuel consumption. The device consists of a combustion chamber made from 4-inch A283 Grade C steel pipe, a fuel tank made from 2-inch steel pipe, a support frame made from 40×40×3 mm SS400 angle iron, a 52 cm hot-air pipe, a ¼-inch valve, and a blower. Test results show the burner stove reached the target drying temperature of 50–55°C, with an average maximum temperature of 55°C, an average time to target of 17.93 minutes, and an average fuel consumption of 253.33 ml. These results indicate that using waste oil as a heat source for coffee-bean drying is a feasible, efficient, economical, and sustainable solution.

Abstract

Penelitian ini mengkaji performa aerodinamika dan kekuatan struktur bilah turbin angin yang terbuat dari kayu lokal pada kondisi angin wilayah Sumbawa, Indonesia. Pendekatan numerik digunakan dengan menerapkan Teori Blade Element Momentum (BEMT) untuk analisis aerodinamika dan Metode Elemen Hingga (FEM) untuk simulasi struktur. Airfoil S826 dipilih karena memiliki rasio gaya angkat terhadap gaya hambat (Cl/Cd) yang unggul. Bilah yang dirancang dievaluasi melalui simulasi menggunakan perangkat lunak QBlade dan SolidWorks. Hasil menunjukkan bahwa bilah mampu mencapai koefisien daya (Cp) maksimum sebesar 48% pada Tip Speed Ratio (TSR) 6–7, dengan daya keluaran maksimum 1287,5 W pada kecepatan putar 324,7 rpm. Analisis struktur menunjukkan bahwa kayu jati memiliki tegangan dan deformasi yang lebih rendah (12,41 MPa dan 29,34 mm) dibandingkan kayu mahoni (54,06 MPa dan 61,27 mm), sehingga kayu jati lebih cocok digunakan sebagai bahan bilah. Penelitian ini merekomendasikan penggunaan kayu jati sebagai alternatif bahan bilah turbin angin skala kecil yang efektif dari segi biaya dan layak secara struktural di wilayah tropis terpencil.
