This research was conducted to test the jig design that can be used in the Friction Stir Welding process on the fillet connection of two aluminum plates. The research method used is the experimental method in the engineering laboratory of the Muhammadiyah University of Sidoarjo. The jig design is a V shape for the aluminum plate base facing up so that the Friction Stir Welding welding is done vertically. The type of aluminum used is AA 6061-T6. The experimental results show that the jig can function well to support Friction Stir Welding at fillet joints using a chisel that has convex shoulders and a small degree of inclination. Jig design with three V plate supports can withstand tool pressure and provide stability during the welding process.Keywords – Jig, Friction Stir Welding, Aluminum

Diesel engined vehicles are one of the biggest causes of air pollution. Exhaust emissions will continue to increase along with the growth in the number of motorized vehicles, especially for commercial vehicles. The main purpose of this study is to determine the quality of fuel can affect the level of smoke density in diesel engines. This research was conducted by testing sampling on a motor vehicle that is commonly used by the public, namely the Mitsubishi L300 in 2007 production using a Smoke Tester. The test mechanism utilizes different fuel variables, namely: Bio Solar with Additive Substances, Solar Dexlite and Pertamina Dex. From the test results, the highest smoke density value was achieved on Bio Solar fuel with additives at 4200 rpm engine speed with a value of 34.1%.

In the internet of things, one of the current developments is smartphone-based water automation which makes it easier for users to control water. The working principle of this research is the water contained in the water storage tank if the water level is below 25 cm then the water pump (water input) will be active until the water is above 25 cm. Then the solenoid valve (water output) can be opened and closed via the Blynk application. When the solenoid is opened, the water in the holding tank will pass through filters 1 and 2 into the filter reservoir. The water in the filtered reservoir will measure the level of acidity and turbidity and then display it on the Blynk application. The results of this study, the water filter can reduce the level of turbidity of water by 0.568 NTU and increase the level of acidity by 0.132. The PH sensor used has an accuracy rate of 93.53%. The Turbidity sensor or turbidity has an average of 1.00 NTU in measuring clean water (Aqua).

This research is based on late payment data from UD Delta customers which affect all production processes that occur in UD Delta. The purpose of this study is to predict the character of the customer as a basis for analyzing the delay in the payment process that hinders the company's production. The datasets tested were 30% of the 600 data, which were divided into 1 id, 7 attributes and for the prediction classes 'No Problem', 'Slightly Problematic', and 'Very Problematic'. This study collects data by means of non-participant observation, namely data on UD Delta's bookkeeping. The process stage is processed using the python programming language with classification methods and naive bayes algorithms. The results obtained from this study are in the form of calculations that state the number of customers grouped into 3 categories, namely with correct predictions as much as 51%, incorrect predictions as much as 49%. From the results obtained, it will be taken into consideration by the company in processing the existing processes within the company as a step to develop the business carried out so that it is more optimal.

Analysis of Bending Strength of Inert Gas Tungsten Welded Connections with Variations in Argon Gas Discharge and Strong Current on Aluminum 5083: Analisa Kekuatan Bending Sambungan Las Tungsten Inert Gas dengan Variasi Debit Gas Argon dan Kuat Arus pada Aluminium 5083 Purgiantono, Purgiantono; Fahruddin, A'rasy

In the technology industry, metal raw materials such as steel and aluminum have an important role in the production process, as so far there is no metal that cannot be joined by welding. Metal Inert Gas (MIG) welding method is a gas arc welding that uses a welding wire as well as an electrode. In the Metal Inert Gas (MIG) welding process, the heat from this welding process is generated by a welding arc formed between the wire electrode and the workpiece. The purpose of this study was to determine the tensile strength of the welding results in the connection process with Metal Inert Gas (MIG) against aluminum (Al) 5083 series 6 mm thick, the welding was carried out with various current strength treatments, namely 120 A, 130 A, 140 A. and Argon gas discharge 5 lt/minute, 10 lt/minute, 15 lt/minute in each welding process. This research is useful to know and understand about the analysis of the welding process on aluminum 5083 with a thickness of 6 mm with Metal Inert Gas (MIG) welding process using vertical (3 grove) welding techniques. The method used in this study is the analytical method, which is a method for testing by adding different treatments of current and discharge variations of Argon gas during the welding process of the specimen, so that different welding strengths will be obtained in each specimen.
