Brass electroplating process has been analyzed on the steel surface for the thickness and hardness of the coating. The electroplating process was carried out on low carbon steel ST 37 by varying the time (10 minutes, 15 minutes, 20 minutes and 25 minutes), and the temperature of the solution (40 °C, 45 °C, 50 °C, and 55 °C). To determine the quality of the coating results were observed using a stereo microscope and Vicker hard test equipment to measure the thickness and hardness. The test results show that the increase in time and temperature is proportional to the thickness and hardness value obtained. The lowest average thickness and hardness value was 11,323 ?m 182.4 VHN at 40 °C with 10 minutes coloring time. While the highest average thickness and hardness values were 29.333 ?m and 218.8 VHN were obtained at a temperature of 55 °C for 25 minutes. The observations showed a significant increase in thickness and hardness values after 20 minutes. This shows that the higher the solution temperature, it will reduce the absorption of hydrogen into the sludge resulting in an increase in the surface hardness of the resulting layers due to more sediment attached to the cathode. The increase in time and temperature of the solution given is directly proportional to the thickness and hardness value produced on the metal surface.

Modifikasi Kapasitas Belt Conveyor dari Kapasitas 400 Ton/Jam Menjadi 600 Ton/jam di Indarung IV PT. Semen Padang Fanani; Rahmadhani; Mulyadi; Aidil Zamri; Yuli Yetri

Belt conveyor is a means of transportation used at Indarung IV PT. Semen Padang. Belt conveyor functions to move material from one place to another both in short distances and long distances with a certain slope. The capacity of limestone conveyor belt owned by Indarung IV is 400 tons/hour. However, this capacity is no longer able to meet the needs of limestone as a raw material for making cement in Indarung IV which currently reaches a capacity of 600 tons/hour. For this reason, an analysis of the 400 ton/hour capacity conveyor belt is still capable of transporting the limestone material with a capacity of 600 tons/hour, using the CEMA (Conveyor Equipment Manufacturer Association) standard. From the calculation results obtained belt conveyor parameters for a capacity of 600 tons/hour such as maximum belt capacity, belt speed, as well as the motor power and gearbox power needed for a capacity of 600 tons/hour. Where, some of these parameters exceed the value of the parameters of the conveyor belt capacity of 400 tons/hour, so the 400 tons/hour conveyor belt is unable to carry a load of 600 tons/hour. Replacement of some components is needed so that a load of 600 tons/hour can be transported.

A research has been conducted about Troubleshooting that occurs in the Caterpillar Engine G3408 generator Set which aims to analyze the causes of the hydraulic lock and determine how to solve the problems that occur in the Caterpillar G3408 Engine Generator Set. The research method is to perform detection, diagnostic, and repair on the engine by doing a visual check, looking for the root of the problem and doing the test. The results are engine has a hydraulic lock caused by a damaged one of the components of the Air Intake and Exhaust System. The after cooler is also damaged due to its long service life, causing the coolant to enter the combustion chamber. From the overall analysis it is concluded that the cause of engine failure is one of the components is damaged due to a long service life and to overcome this is doing repair and replacement of components on the After cooler with new components and do the periodic maintenance on the Caterpillar G3408 Engine Generator Set.

Press Tool is designed to be able to make mass and uniform products in a relatively short time. One of the products that can be produced using a press tool is the supporting component of the pantograph jack. Pantograph jacks are used in the automotive industry. The need for this product increases along with the increasing demand for motorized vehicles, especially cars. The production stages of supporting components using a press tool include: trim stop, piercing, notching, bending, cropping and deep drawing. Press tool design methods include: determining the design and supporting dimensions, calculation, simulation, and analysis using solidworks simulation analysis. The thickness of the plate that is safe to use for the manufacture of supports is 3 mm with ST 37 material. The planning dimensions of the press tool are (320 x 250 x 217) mm. Press tool components include: shank, punch, dies, top plate, bottom plate, pressure plate, punch holder, stripper plate, guide pillar, guide bush, bolt, and guide pen. The materials used to make press tool components include: ST 37, ST 42, brass, HASCO standard, AISI standard, and Polman Bandung standard. The total force that occurs in the manufacture of supports is 442798.2 N.

Welding (Welding) is an activity of connecting metals by going through the metal's liquid phase before finally solidifying and creating a connection. Welding techniques are increasingly widely used in building construction and machine construction. In addition to connecting metals, welding also has a function as a cutting medium. Welding and cutting is a job that requires accuracy. Welding work without tools will result in inaccurate results, so it requires an expert welder to get the desired results. The purpose of this research is to make a plate cutting tool called the Welding Fixture Table. This tool is used to help hold the workpiece in the form of a plate so that the cutting process is easy. This tool has the ability to clamp a maximum plate with a thickness of 6 mm of 750 mm x 610 mm with a weight of 21.6 Kg and can be adjusted to a smaller size, equipped with a sliding shift system on the table top to adjust the size of the workpiece clamping, as well as a system rotation which will make it easier for the operator to select the desired welding or cutting position.

Currently, the technology for supplying water is still mostly using pumps with electric motor drives. Most of these pumps are dependent on electrical energy or fuel oil as the pump driving energy. One of the technologies being developed is the hydraulic ram pump. The hydraulic ram works on the water hammer principle. When the fluid flow is stopped suddenly, the change in momentum of the fluid mass will increase the pressure suddenly. This increased pressure is used to lift some of the water to higher ground. So a hydraulic ram pump is designed that uses the potential energy of water as its driving force. In designing the hydraulic ram pump that the author did, using a variation of the height of the air tube with a height of 100 cm, 80 cm and 60 cm with a diameter of 3 inches and an outlet pipe diameter of inch with a water source height of 0.5 m. From the experiment, the maximum pump discharge was obtained on an air tube with a height of 100 cm with a discharge of 0.010309 L/s.
