Touchscreen is a technology used in the process of user selection access to control a function. In general, the touchscreen uses a cover that is used to cover the electrical function. The process of making cover control generally uses printing media with black INK material where in nature there are many chemical ingredients. In this study, an analysis of the nature of carbon will be carried out on the sensitivity of the control sensor in receiving a command. The results of the analysis found that the carbon material in INK affects the sensitivity quality of a sensor control function by 80% failure, so it is recommended for the forming agent of the base cover.

Vinyl Bag is part of the manufacturing process where its use is for the packaging process. The packaging process generally uses a variety of materials such as EPS, LDPE, LLDPE,HDPE Foam and others, which aims to protect the finished goods of a product from defects. One of the materials used in the packaging process is Linear Low Density Polyethylne (LLDPE). The problem that often occurs during the printing process on HDPE material is pell off where the printing material cannot adhere to the surface of the Vinyl Bag perfectly. In this study, an analysis will be carried out using UV Static Surface on Vinyl Bags before the printing process is carried out. The results of this experiment showed that the printing results on 100% Vinyl Bags had no defects compared to those without the UV Static process, which was 20%. This is caused by the surface of the material that is not smooth and also the unstable structure of the material without UV processing. So that the pell off on the vinyl bag without UV failed 80% of the 15 samples.

The body caliper is a crucial component of the braking system designed to ensure safety and security while driving, especially on two-wheeled vehicles. For the production of the body caliper on the , Aluminium Alloy AA 319 T6 is used due to its high strength and lightweight properties, consisting of 90.48% Aluminum, 2.7% Chromium, 6.6% Silicon, and 0.22±0.02% Magnesium. The manufacturing process involves melting the metal and pouring it into molds. Electromagnetic penetration is used to detect conductive structures and cracks in the raw material. Hardening tests are conducted using optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and X-ray diffraction (XRD), as well as hardness measurement and tensile testing.

Die casting is part of manufacturing process for making metal product, especially internal combustion engine of vehicle. Molding is component for making product from metallurgy process or polymer process. Basically, all part of molding process will be using 3 conditions of process. First is solid raw material for process production, second is melting process of raw material for making product using molding and third is solid for part of finish product after process molding process. In this research will analyze of molding process and structure of engine for internal combustion engine vehicle. Mold casting will be using specification for SUV capacity 2.7L. basic raw material is silica sand, resin, bentonite, and sea coal. The result show that after process mixing optimal pressure from machine to molding is 109675,8 N. and spot test check result show that, after process die casting no any crack founding by 10 specimens of engine of vehicle.

Steel is part of raw material for manufacturing process making a product. Ferro Casting Ductile is part of manufacturing process from iron ore to be metal part using casting process. Die casting is a part of manufacturing process especially in automotive industries for engine of vehicle production process. this research will be focus on casting process, Ferro Casting Ductile (FCD). In this research using material steel HDF 12 Material, in this process production Magnesium, Pig Iron, Scrap, Silicon, Carburizer, Inoculant and Slagtol. Manufacturing process is melting process of all raw material using temperature (melting point) at 1100 - 1400 ºC. When Specimen finish to process production will be analyze using spicrometer and SM machine for check of characteristic material and structure for crack issue. The result show that after casting process, the HDF12 have composition rate iron (Fe) content, namely 93.37% and also carbon (C) 3.82% and silicon (Si) 2.31% after check using.

The turret machine is one type of lathe that has The main characteristic is that the tool for sequential operations can be set in readiness for use in the appropriate sequence. This turret machine is intended for cutting, drilling and smoothing work pieces. The process of making this collar aims to find out what material is used and the function of the collar. In the process, the iron is clamped with a chuck then the drill which is located on the loose head is brought close to the workpiece then the chuck rotates so that the workpiece has a hole with an inner diameter of 11.2 mm, after that the workpiece is sprayed with bromus liquid to ensure that the workpiece does not rust easily and does not experience excessive heat which can damage the workpiece. Entering the next stage, the workpiece is cut to a length of 9 mm, and the next process is that the workpiece is placed in a jumper. The cumper process functions to smooth the workpiece so that it is not rough before entering quality control. After that, the object enters quality control. In quality control, the work object is measured using a jig measuring tool to determine whether the work object is OK or NG. The aim of this process is to make quality spare parts that are safe to use. The disadvantage of the turret machine is that it is a manual process that requires hand speed and expertise in operating the turret machine..

Hydroelectric Power Plants (HPP) are a type of power plant that utilizes renewable energy from water flow. The hydroelectric system works by converting the kinetic energy of flowing water into mechanical energy, which is then converted into electrical energy. Water flows through a penstock directed towards the turbine, where it strikes the turbine blades, causing rotation. To maintain the stability of the turbine's rotational speed at the Maninjau HPP, a governor system is used. The Maninjau HPP consists of four generating subunits with a nominal rotational speed of 600 rpm. The governor system functions to stabilize the turbine's rotation at the nominal speed of 600 rpm, as the speed affects the generator's output frequency. The stabilization process is carried out by adjusting the Guide Vane openings, which are the blades surrounding the turbine. The Maninjau HPP has a speed drop of 3%, with a frequency reduction of 1.5 Hz. Additionally, a frequency change of 0.1 Hz will result in a load change of 0.13 MW.

Plastic Injection Molding (PIM) is a production process for the formation of plastic material from granular resin material used in making a manufacturing component. Defects that generally occur in plastic injection molding are short molds, which are conditions where the resulting part is not completely filled with plastic material. The research discusses the analysis of heat and E on the cover air flow against short mold defects. The method used is the actual calculation method and the actual analysis of the injection part and then compare the results of temperature variations. The material used in this research is ASA with grade LM5201F which is inserted into injection molding with a pressure of 96 Mpa. The temperature to be analyzed is 130̊C in the barrel. The results of this study show that a temperature of 150̊C with a cooling time of 21 seconds can overcome the problem of short mold on the cover air flow. For the results of E at a temperature of 130̊C, it has a higher value, namely 1.73, this is due to the cooling time which takes longer.
