The landing gear of the Airbus 330 uses a green hydraulic system, which is currently still found several leaks which result in a decrease in flight safety because the propulsion force on the landing gear does not function normally so it must use the freefall system when landing. This study analyzes the events that cause leaks of the flexible hose system, swivel valve and pitch trimmer. Flexible hose in AircraftmMaintenance Manual has no limitations when a rapture occurs, while for swivel and pitch trimmers there are still limitations. The hydraulic system leak data was taken in January – December 2020 with a total of 49 cases of leaking hydraulic system cases in the landing gear area, where flexible hose has a very high leakage rate compared to other cases. To identify the causes of hydraulic system leaks, this study used ultrasonic internal leak measurement tools and hydraulic fluid analysis methods.

Biogas is gas produced by bacteria when organic matter undergoes a fermentation process under anaerobic conditions, and will produce methane gas which is temporarily stored in a container called a biogas bag. The biogas bag needs to be controlled to ensure the biogas bag remains safe. The control system is in the form of a two-position control because it has the advantage of being cheap and simple, besides that the solenoid valve as an actuator has a non-linear output property. To detect the capacity of the biogas bag, the HCSR-04 proximity sensor is used as feedback on the set point value that is set, which is 50 cm for the maximum set point and 30 cm for the minimum set point. The results obtained by the proximity sensor is able to read the distance with an accuracy of 5.8% and the On-Off control has a response of 0.25 seconds.

Flame is a phenomenon of rapid oxidation of an element in a physical and chemical reaction process that produces heat, light, and other chemical products. Flame testing aims to quantify the presence of a particular element through the emission spectrum of each element. In addition, the physical characteristics of the fire object were also observed. Image-J software is one of the practical supporting applications that is often used for observing flame objects specifically in the fields of chemistry, physics, and energy. Experimental results have shown the level of accuracy of object dimensions and spectrometry with an accuracy rate of 97%. Differences in measurement ranges are often triggered by the image of the object and the foresight of the researcher.

The contact between ball and tennis racket is a collision phenomenon. The ball exerts a force on the racket which causes deflection. This study aims to obtain the deflection characteristics of a tennis racket due to ball contact. The research was conducted by experiment with Kinetic brand rackets. The racket is clamps on the grip. The ball used is Nassau brand with 0.058 kg of mass. Free fall is arranged 1, 2 and 3 meters heights, with 3 hitting points on racket string. The deflection measurement uses the pen method at 5 points on racket frame. Five points are arranged sequentially from the grip with 6 cm distance. Data collection was carried out with 3 repetitions to get average value. The deflection was measured using a caliper with 0.01 mm accuracy. The results show that the deflection has a linear characteristic and depends on the momentum of the ball

Wood chipper machine is a tool used to crush wood waste into powder (particles). This study aims to determine the effect of the distance between the blades and the hopperangle due to wood chipper machine performance. The distance between the blades was varied by 2 mm and 3 mm. The hopper angle was varied by 45o, 50o, and 55o. Measurement of sengon woodparticlesis done by using wire-mesh with sizes of 1.19 mm, 0.25 mm, and 0.15 mm. The result of the study show that there is an effe ct of the distance between the blades and the hopperangle dueto wood chipper machine performance.

The characteristic of fluid-flow and heat-transfer on a circular cylinder with particular pattern is frequently used in various branches of modern technology today. The amount of heat transfer when fluid cureent passes through circular cylinder is expressed by Nusselt number parameter, eiter local Nusselt number (NuФ) or average Nusselt-number. Forced convection heat transfer on the circular cylinder with a staggered-type of using Reynolds-number (ReD) varied as the-value of 80, 200, 5000 while the tranverse-pitch (2D, 2D). The fluid inlet temperature entering shell is 350oK and the tube temperature is 300oK, which is modeled whith-Gambit 2.4.6 and simulated using Fluent-6.3.26 whith turbulent model k-w SST 2D steady-flow to obtain data related to the velocity profile and temperature distribution. From the simulation results obtained visualization contour of velocity, temperature and Nusselt number distribution. The smallest Nusselt value is at ReD 80 then ReD 200 and the highest is at ReD 5000.

Damage from the forklift will cause problems that will hamper other activities. This is often overlooked where the lifting equipment / forklift must get good and continuous maintenance in order to maintain the performance of the tool. This study aims to plan periodic maintenance of the forklift in order to avoid damage that can stop the operation of the forklift. The method used in this research is to collect data, make direct observations of the damage that occurs to the hydraulic pump, and conduct interviews with experienced mechanics who handle the forklift. The results of the research are in the form of maintenance planning with Preventive Maintenance and Corrective Maintenance methods, namely the implementation of daily, weekly, monthly and yearly maintenance work. In daily maintenance, inspections will be carried out, check all lubrication and perform service.

Periodical Service is engine care to reduce the frequency of damage and duration of the injury. Good and efficient care can keep the tool's operating times, keep it in production, reduce the cost of unexpected damage. The purposes are to: (1) Perform Periodical Service activities during the activity, (2) Find when Periodical Service consists of PS 250, PS 500, PS 1000 and PS 2000, (3) Know the results of Periodical Service. Implementation of the Periodical Service fulfilled at PT. Madhani, especially in Volvo trucks, includes changing engine oil, changing engine oil filters, changing transmission oil and filters, changing final drive oil to the battery and electrical checks. With the Periodical Service data program showing PA (Physical Avelaibelity) results of over 95%, MTBF (Mean Time Between Failures) of over 3000 hours, and MTTR (Mean Time To Repair) of less than 20 hours, this is very effective and efficient to increasing production.

Composites can be arranged using natural fibers, such as jute fibers then combined with woven roving. Jute fiber is an organic waste that is widely obtained as a burlap sack hole. Synthetic fibers have the advantages i fibers that are strong, corrosion resistant, heat resistant and easy mass produce. Making composites can be done several methods, one which is using vacuum bagging method with a technique using pressure direct resin fibers. researcher's goal is to determine characteristics tensile tests and bending tests using vaccum bagging. (hybrid) In form a yield value 62.94 Mpa and tensil 85.9. Non hybrid fibers can be yielded 28.7 Mpa and tensile 32.9 Mpa. While bending test on hybrid fibers obtained bending strength with a value of 1,126.96 MPa. In non-hybrid fibers, bending strength results were obtained with a value of 643.30Mpa.
