Abstract

Maintenance is taken to maintain the reliability of the components that support overall nurse performance. One of them is the landing gear which functions for all aircraft movements on the ground including taking off, landing, taxing and parking, and holding the aircraft's load while on land. Nose wheel assy is provided to hold the nose of the aircraft and maneuver while on the ground. Based on information obtained from the engineering department as well as looking at the maintenance logbook on the ATR 72-500 aircraft there was a problem with the nose wheel assy. Where these problems can result in the movement of the aircraft will be problematic. The method used is the Weibull distribution analysis method, the main objective is to determine the failure rate and the reliability of these components as well as to determine the characteristics of the failure modes caused. The parameters used in this distribution are the shape parameter (β) and the scale parameter (h). From the calculation analysis results, it can be seen that the nose wheel assy component based on time failure will function until it fails at the age of 585 hours 38 minutes and β is 3.513864. Following the provisions that apply to values β 1,the type of failure that occurs is a type of failure to wear out. While based on the cycle will function until experiencing failure at the age of 398 hours 13 minutes and β is 1.258549 Under the provisions that apply to values β 1, type failure that occurs is a type of wear out. This type of failure has the property of increasing the failure rate with increasing use, therefore for nose wheel, assy components more effective preventive maintenance is applied.This type of failure has the property of increasing the failure rate with increasing use, therefore for landing gear, assy components more effective preventive maintenance is applied.

Abstract

Orifice is a device that is placed in a pipe flow to inhibit the flow of fluid and cause a pressure drop. The measurement of the flow rate (flow rate) is obtained from the difference in pressure due to the pressure drop. In this study, it analyzed the influence of differences in plate orifice thickness variations used ranging from 2 mm to 4 mm thick with variations in increments every 0.5 mm with an orifice center hole diameter of 1.5 cm. Orifice placement is placed in an area whose speed profile is still changing or called the entrance region with a pipe diameter used 2.54 cm (1 Inch) diameter in the pipe. Then along the entrance area are paired 12 piezometer points along 75 cm with a position of laying 6 piezometer points before the orifice valve and 6 piezometer points after the orifice valve and in this experiment set the Re value to 3 Variations of Re, namely Re 1: 9784.5; Re2: 14647.5; Re 3: 19510.45 and this experiment was carried out at a temperature of 27 °C. In this study, the results were obtained for the highest irrecoverable pressure drop value located in the flow discharge with Re 19510.45 and at the thickness of the plate orifice 4 mm with an irrecoverable pressure drop value of 3033.01 Pa and while for the lowest irrecoverable pressure drop value, it was located in the flow discharge with a value of Re 9784.5 at an orifice plate thickness of 2 mm with an irrecoverable pressure drop value of 548.26 Pa. The highest discharge of coefficient (Cd) value lies in the flow discharge with a value of Re 14647.5 at the plate orifice thickness of 3.5 with a Cd value of 0.718 and while for the lowest discharge of coefficient (Cd) value lies in the flow discharge with Re 14647.5 with an orifice plate thickness of 2 mm with a Cd value of 0.609.

Abstract

The process of drying palm sticks carried out by umkm in Kampar Regency, precisely in the Terentang mine, still needs to be solved in the drying process, which only has sunlight and changes in hot weather in the quality drying palm sticks. Therefore, an oven is designed to improve the quality of drying palm sticks using a double blower system and a branched pipe. This oven is manufactured for an open iron drying room measuring 3x3 cm with volume dimensions of 100 cm3, then for the heating room using a hollow iron measuring 3x3 cm with dimensions of length 50 cm, width 50 cm, and height 50 cm. Heat flow pipe using a pipe of 2 inches along the 800 mm and connected using a branched pipe 50 mm long with a pipe size of 1 inch as much as 4 sections that lead to each rack in the oven chamber. Based on the calculation of the design capacity of this palm stick drying oven, the total capacity of this oven is 28.8 kg on each shelf. However, from experiments that have been carried out with the drying process of palm sticks at full capacity, it is measuring the water content of each shelf is uneven. The bars on each frame and the rods in the middle pile do not experience differences in air content because the hot air obtained is less when compared to the top bundle of posts and the bars at the bottom.

Abstract

Sand is the main ingredient in the construction process, so based on its function, size separation is needed. This size separation is done by sifting sand. Based on the survey, many construction or industrial workers use traditional methods of sifting sand, and the results obtained are less effective in terms of capacity and working time.The rotary system sand sieving machine is planned as a tool to make it easier to sift sand. The sifter tube is designed with 2 sieves. The first filter uses a mesh size 6 and the second filter uses a mesh size 8. This is done to produce 3 grades of sand.This rotary system sand sifter machine aims to sift sand with 3 different sieve results, namely fine sand, medium sand, and gravel. Fine sand is used as a mixture of plaster for concrete walls, medium sand is used as a mixture in bricklaying, and gravel is used as a mixture of foundation casts. In the mechanical movement system using a 1 Hp AC motor as a source of rotation, then the rotation of the motor is transmitted through a reducer with a ratio of 1:40 and then forwarded to the shaft. On the shaft there is a filter for sifting the rotary system sand.This research was conducted with 3 variations of the angle of the sieve which is 10°, 15°, 20°. In testing the maximum capacity in one test is 30 kilograms. The best sieve results were obtained from testing with a 10° sieve angle using dry river sand and dry land sand.

Abstract

The potential of rooftop solar power plants at Semarang State Polytechnic Mechanical Engineering Workshop has been researched. This study discusses one of the factors that affect the radiation received and energy sent to the grid, namely the angle of inclination in the solar panels The average radiation data received by solar panels with variations in tilt angle between 0 to 30° and azimuth angles at 0° facing north and 180° facing south are simulated using Helioscope software. Based on the results of mathematical calculations, it is estimated that the relationship between the tilt angle of the solar panel and the radiation received and the energy sent to the grid will form a quadratic curve. From the results of data processing with the Regression Quadratic Method, it was obtained that the data match was 99.6%. The results of calculations using the quadratic equation show that the angle of inclination of the solar panels for installation of a rooftop PLTS in Machine Workshop Polines is 11° with a radiation of 1775.6 kWh/m2 and a energy production of 13575.9kWh.

Abstract

Pin-On-Disc is a tool used to test a material's friction and wear levels. This tool is also one of the tribometer components. Pin-on-Disc uses a ball-shaped pin and a disk of ST 60 wrought iron as a disc in this test. This test aims to see or determine the volume of wear produced by pins with SAE40 and SAE140 lubricants and the importance of pin wear without lubrication. Lubrication influences the material or test specimen in this tribometer test. In this test, they are using a simple Pin-on-Disc Tribometer. The results obtained from this test are that the test without using lubricant shows at coordinates 0.0704 N, while the test with SAE40 lubricant shows at coordinates 0.07027 N, and testing with SAE140 lubricant is at coordinates 0.0703N.
