Abstract

Hydraulic system is one of the systems on the heavy equipment unit which is very important for students to understand. The problem that exists in the heavy equipment engineering laboratory at this time is that there is no hydraulic pump test equipment to determine whether the pump that has been repaired is in standard condition or not. To overcome the problems and to support the lecture process, the hydraulic pump test equipment was made. as a tool for testing the feasibility and specifications of the gear type pump. After all the design processes and assembling the required tools, a series of tests will be carried out. The form of tool testing is carried out in the form of pump flow liters per minute, pump pressure in various RPM variations. From the test results, it was found that at RPM 900 the pressure was 100 Psi Flow reading 11 and Flow rate 209, at RPM 1100 pressure 12 Psi Flow reading 15 and Flow Rate 285, At 1372 Pressure 14 Psi Flow reading 19 and flow rate 361, RPM 1500 Pressure 16 Psi Flow reading 19 and Flow rate 437

Abstract

Design and manufacture of this simulator aims to explain how the movement of the differential components. The components of this differential simulation consist of a differential case, pinion gear or spider gear, side gear, spider shaft, electric motor, pulley, v-belt and dimmer (motor speed controller). The method used in making this simulator is to start by first making a simulator design and then continuing with the collection of tools and materials needed. From testing the components of the simulator tool which was carried out for 50 minutes, it was found that every 10 minutes the temperature increased due to the lubrication system that was not maximized. Tests to determine the correlation between the dimmer and the RPM of the electric motor, it was found that any decrease in the resistance value will result in an increase in the RPM value of the electric motor. These results also show that the maximum value of the motor RPM after being assembled is 1435 RPM. Then the test when given a load found that the shaft axle rotation speed of the differential will change if there is a load on one side. From this test, it can be seen that there is an increase in the RPM value on the side of the shaft axle which rotates freely when the other shaft is given a load. With this simulator, it can also provide an overview of how the movement of the differential gears contained in the axle of a unit vehicle so that you can understand how it works

Abstract

The hydraulic oil filter is one of the components contained in the hydraulic system which functions to filter the impurities contained in the oil so that it does not circulate into the system. The purpose of this study was to determine the performance of the original and non-original filters in relation to the damage that occurred to the control valve. The results indicated that the damage to the spool valve was caused by hydraulic oil contaminated with water, resulting in corrosion on its surface. Visual inspection of the hydraulic oil filter reveals particles found in the filer element.

Abstract

The alternator plays an important role in supplying the battery, lighting accessories and turning on the unit at the time of starting, therefore it needs more attention to it. Damage can occur at any time, and finding the problem with it presents its own challenges. Equipment such as a multimeter/avometer is needed to analyze the damage. Visual inspection, testing, and measurement are steps that must be taken to be able to find damage that occurs in the alternator. The charging system can be disrupted if there is an operational problem with the alternator component. This can be identified through an examination of the damage that occurred. Maintenance/maintenance on the components of the charging system must be carried out periodically so that the electricity supply remains optimal.

Abstract

Tofu industrial wastewater has a Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) value exceeding the environmental quality standards. The high value of COD and TSS of tofu industrial wastewater is caused by the high content of organic matter and if there is no treatment, the liquid waste of the tofu industry can cause pollution in the aquatic environment. One of the  biological processing of tofu industrial wastewater is the bioremediation process using microorganisms. This study aims to determine the ability of the effective microorganisme-4  (EM-4) on  reduction  of COD and TSS in tofu industrial wastewater. This research was conducted by mixing tofu industrial wastewater and effective microorganism-4 solution into the reactor with various concentrations of EM-4 3%, 5%, 7% and 10% and residence time for 2 days, 4 days and 6 days. The parameters were measured of COD, TSS and pH. The results showed that the tofu industrial wastewater treatment using EM-4 solution with a concentration of 10% for 6 days gave the best results, namely a decrease in COD by 70%, an increase in pH to 8.36 and TSS by 180 mg/L
