Abstract

The Material Test Process of Gear Sprocket includes the process of cutting the material used as the Material Test sample which is mixed or not mixed. In the sample that is mixed, namely the base metal that has been cut with a value ratio of 10:2 Ounce of Material Gear Sprocket 10 and Tin Material 2 Ounces, fusion will be carried out for the process of blending/unifying the two types of material as sample material. Test the material with the mixing, while the Gear Sprocket material sample that was not mixed was also taken a load value of 10 Ounces, for the test sample where the mixing was not carried out. The test results data from the Gear Sprocket material sample with Tin mixing with four tests from several different surface parts obtained the value 51.5, 55, 50, 53 kgf. While the sample of the Gear Sprocket material without mixing the tin, the results obtained are the values ​​of 50, 51, 50, 50 kgf. In combining the Tin Material with the base metal Gear Sprocket with the ratio of 2 Ounce Tin Material and 10 Ounce Gear Sprocket Material, the hardness results are unstable, so the value obtained from the material being treated is obtained a value that is less likely, while the material test value of the Material Gear Sprockets that are not combined have good results from each surface even though the hardness value is slightly smaller than the result of the material being treated.

Abstract

VVT-i (Variable Valve Timing with Intelligent) technology basically works to optimize engine torque at every speed and driving conditions. The mechanism will eventually produce more efficient fuel consumption and lower exhaust emissions. The workings of VVT-i technology are quite simple, namely to calculate the optimal valve opening time, the ECU (Electronic Control Unit) will adjust the engine speed, air intake volume, throttle position and water temperature. In order for the valve timing target to always be realized, the crankshaft position sensor provides a signal that is a correction response. This VVT-i system will correct valve timing or fuel and air inlet lines. Adapted to the gas pedal footing and load borne to produce optimal torque in each rotation and engine load. This technology is also claimed to have excess power that is far more optimal and saves fuel consumption, and is environmentally friendly.

Abstract

Rice is the staple food most consumed by Indonesians which is produced from milling dry unhusked rice grain. In the dry unhusked rice grain milling process, rice has different forms, namely whole and cracked rice. This is due to the poor quality of the paddy rice. The different in forms has led to a different selling value. Whole rice is more expensive than the other. Therefore, sorting was done to obtain the differences. This study was carried out to build rice sorting device with a system in the form of a launch crank mechanism as a vibration system. This device has several components consisting of two mesh and two turnbuckle eye & eye as the sieve tilt adjustment. In the tilt experiment, two variations of the angle were obtained, namely an angle of 10° and an angle of 15°. This device uses a single-phase electric motor as the driving force of the launching crankshaft. The transmission system uses a pulley and a v-belt from a single-phase electric motor that is passed to the pulley. From the test results that have been carried out two-angle variations with a capacity of 10 kg. At an angle of 15°, 69% pure rice is obtained with less optimal results because the slope of the angle is too steep. Whereas at an angle of 10°, the yield of pure rice is 85% which has a less angular slope so that the sorting of rice is maximized.

Abstract

Workload of employees at PT. RSI in the pressing department is still low, because in the pressing section the division of work for each employee is not optimal or evenly distributed. So it is necessary to do research with the title Analysis of the Optimal Workforce at PT. RSI. The method used for testing the optimal amount of load is the Work Load Analysis (WLA) method, which aims to calculate the optimal workload and number of workers at PT. RSI. The sample in this study were 15 employees in the pressing department which were divided into 4 sections, where section 1 had 4 employees, section 2 had 4 employees, section 3 had 4 employees, and section 4 contained 3 employees. The results of this study indicate that the workload before the research in section 1 was 52% to 70%, part 2 from 51% to 68%, part 3 from 56% to 75%, and part 4 still 71% because there was no reduction in labor., because the workload in section 4 is optimal. So the optimal number of workers in the pressing department is 3 employees in section 1, 3 employees in section 2, 3 employees, and 4 still 3 employees.

Abstract

PT. XXX as the yield management company becomes a plastic seed product that is ready to be used as raw material in other plastic companies. Apart from the garbage production of PT. Garuda Prima Sentosa also gets unused plastic waste from domestic and foreign suppliers. In the process of processing plastic waste, still uses the sorting power manually obtained by 40 people, the results obtained are also less than the maximum there are still many other materials mixed in plastic waste from 4200 kg of plastic waste can only be repaired by other unused material as much as 915.92 kg per day. This study discusses the centrifugal machine as a separator between used plastic waste from other unused materials and minimizes the sorting power of 40 people to 8 people, and adds the unused material to 1355,308 kg per day. The design of this Centrifugal machine to be able to overcome the problems that exist in the sorting section so that it can produce cleaner plastic seeds and improve the sorting process.

Abstract

Comfort in a room is a necessity for everyone who is in the room, to support the activity in the room and increase work productivity, Air Conditioner is an equipment used to condition the air in a room so that it can reach temperature and humidity according to the conditions air that provides work comfort for people who do certain activities in the room. Therefore, the air conditioning system or air conditioning system (AC) has become a necessity in buildings, offices and housing, all of which can not be separated from the need for electrical energy, especially for air conditioner installations. To get air with the desired conditions, the selected equipment must match the capacity according to the cooling load in the room, for this final project special installation planning for Air Conditioners is done, namely calculations to determine the cooling load according to the room, as well as conductor selection in accordance with the calculation load, from the calculation results, obtained the number of air-cooled loads or first-floor Champion hotel air conditioner is 108,692 BTU / day with a total power of 7,920 watts, and the appropriate cross section based on the count is 1.5 mm2, and the main safety (MCCB) is 25 A.
