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

The activities of gas well exploitation have some problems. One of the problems is the amount of liquid (water) in the tubing column which obstructing the gas production. One of the ways to overcome the problem is to offload activity. One of the important equipment during offload activities is the offloading pump. An offloading pump is used to transfer liquid (water) from the well that has been collected in a vessel to the trunkline. This study aims to see the changes in the performance of the offloading pump between the initial conditions according to the manufacturer's specifications and the current condition after being used for ± 9 years. The type of pump being tested is a multi-stage centrifugal pump model 20 WUC-2R-19. The performance testing of offload pump is done by varying the discharge valve opening by 25%, 50%, 75%, and 100%. After that, compare the actual pump performance with the corrected data using the affinity law. The test performed during the offload process occur, and the fluid characteristics assume to be constant. The results showed that there was a decrease in performance between the initial operating conditions in 2011 with the actual conditions in 2020. The actual capacity of the pump decreased from 24 m3/h to be 23.45 m3/h. The efficiency of the offload pump decreased from the initial condition of 80% to 7.71%. The decrease in efficiency for 9 years is 2.29% or 0.25% per year.

Abstract

A micro-hydropower plant is a small-scale power plant that uses water as its propulsion and the prime mover is a turbine. This generating system is very appropriate to be used in rural areas because this system is easy to manufacture, produces a large amount of electrical power, and is relatively inexpensive to manufacture. Based on the above, it is necessary to design a turbine that supports this generating system, including the Cross-Flow Turbine. To design a water turbine so that there are no errors in the design (such as the cost of making it), then a design is carried out. A cross-flow turbine design is designed with a flow rate (Q) = 1.2 m3/s, head (H) = 17 m with an efficiency of 0.75. The main technical specifications from the results of the turbine design are runner diameter (D) = 510 mm, turbine shaft rotation 471 rpm with a specific speed of 61.33 rpm, water power of 200,124 kW, and producing electric power of 100.86kW.

Abstract

BENGPUSPENERBAD is a central workshop specifically owned by the Indonesian Army in Semarang, where aircraft and helicopters are subject to preventive and corrective maintenance. During the period 2018-2020 the BELL 412 EP helicopters often experienced unscheduled maintenance which resulted in losses resulting in flight failure, this was due to a malfunction in the Main Rotor Blade system. The malfunction of the Main Rotor Blade system is dominated by the hub component, namely on the shaft associated with Crack, Noise and Burn damage, and blade components, namely Corrosions, Nicks, Scratches, Dents, Deformation Holes and Crack. Therefore, the aim of this study is to eliminate failure system and unscheduled maintenance. To eliminate failure and unscheduled maintenance, the authors perform an analysis with the FMEA method and calculate using the distribution method, then design the appropriate activities on the system. The data used for analysis are qualitative and quantitative data, where the authors use data from Time To Failure (TTF) and Time To Repair (TTR). According to calculations using the current distribution we found that the Main Rotor Blade system was on time during the 200 operational flight hours, for which the reliability figure was 0.70. Maintenance activities in accordance with the operational conditions of the main rotor blade operating system are preventive maintenance with activities for tool preparation, inspection or chek, dismantling and servicing, and finally installation and finishing activities.
