Abstract

Welding (Welding) is an activity of connecting metals by going through the metal's liquid phase before finally solidifying and creating a connection. Welding techniques are increasingly widely used in building construction and machine construction. In addition to connecting metals, welding also has a function as a cutting medium. Welding and cutting is a job that requires accuracy. Welding work without tools will result in inaccurate results, so it requires an expert welder to get the desired results. The purpose of this research is to make a plate cutting tool called the Welding Fixture Table. This tool is used to help hold the workpiece in the form of a plate so that the cutting process is easy. This tool has the ability to clamp a maximum plate with a thickness of 6 mm of 750 mm x 610 mm with a weight of 21.6 Kg and can be adjusted to a smaller size, equipped with a sliding shift system on the table top to adjust the size of the workpiece clamping, as well as a system rotation which will make it easier for the operator to select the desired welding or cutting position.

Abstract

Currently, the technology for supplying water is still mostly using pumps with electric motor drives. Most of these pumps are dependent on electrical energy or fuel oil as the pump driving energy. One of the technologies being developed is the hydraulic ram pump. The hydraulic ram works on the water hammer principle. When the fluid flow is stopped suddenly, the change in momentum of the fluid mass will increase the pressure suddenly. This increased pressure is used to lift some of the water to higher ground. So a hydraulic ram pump is designed that uses the potential energy of water as its driving force. In designing the hydraulic ram pump that the author did, using a variation of the height of the air tube with a height of 100 cm, 80 cm and 60 cm with a diameter of 3 inches and an outlet pipe diameter of inch with a water source height of 0.5 m. From the experiment, the maximum pump discharge was obtained on an air tube with a height of 100 cm with a discharge of 0.010309 L/s.

Abstract

The hydroxyapatite (HA) layer on the surface of the implant material tends to crack during the sintering process for layer densification. This causes the process of implant union with bone (osseointegration) does not function perfectly in the human body. This study aims to reduce cracking by increasing the adhesion of the HA layer on the surface of the Ti-6Al-4V Extra Low Intertitial (ELI) implant material. The research used the dip coating method to get a thin and even layer. To strengthen the adhesion of the coating, Zirconium Oxide (ZrO2) was added in commercial HA suspension. The test specimens were heated at sintering temperatures of 800 0C, 900 0C and 950 0C with a heating rate of 5 0C /minute. Layer morphology and cracks were seen using an optical microscope. The percentage of layer cracks will be measured using ImageJ software. The results obtained, the addition of ZrO2 can reduce cracks in the HA layer of the surface of the test specimen. The percentage of cracks decrease with the addition of ZrO2 (17% and 20% weight) to the suspension of the HA layer. These result is certainly good for increasing osseointegration in the human body.

Abstract

The problem faced by partners today is the low technology used in the patchouli oil refining process. The distillation system equipment used is still simple, the tubes are made of used drums and are easy to rust. This service aims to make a patchouli oil distillation device whose tube is made of stainless steel and to test the tool. The implementation begins with a field survey by conducting discussions related to partner problems and the solutions provided. The manufacturing process is carried out in three stages of activity, namely tool design, tool manufacture, and tool testing. The manufacture is carried out in a workshop located in Sungai Sapih, Kuranji Padang. While the test was carried out in a patchouli plantation located in Lubuk Minturun, Padang. The results show that using a tube made of stainless steel produces patchouli oil cleaner than used drum. Therefore the Mitra does not screen after the distillation process. The process of production becomes effective and efficient.

Abstract

One of the effort to lessen worn-out of tool machine is used by spraying coolant (mixture water and oil). Beside that dilution of coolant also function to slow down the rate of corrosion. But practically often arise damage ahead of schedule, so that old age to wear appliance become shorter. This research was conducted to dilution of coolant made with mixture irrigate faucet with oil and pure water mixture (aquades) with oil, were in the reality obtained that dilution of coolant aqueous of quicker faucet of its process of him from at using pure water. This matter was caused by pregnant faucet water of metal minerals able to form salt when mixed with oil, so that will quicken rustiness process. Later; Then for the variation of different composition in the reality more and more oil longer process rustiness happened. The corrosion at tool machine during the time was caused usage of faucet water to make dilution of coolant and also composition making of dilution of coolant imprecise.

Abstract

To maximize the function of the mosque as a place of worship, a community service team has carried out together in the form of counseling and donations. This is done because mosques have a very strategic function in Islamic society, both as places of worship and as media centers for holistic development of the people. This service team is trying to optimize the function of the mosque as a center for community empowerment activities. This community service is motivated by the facilities and infrastructure of the Nurul Hikmah mosque which are still inadequate for the needs and comfort of worship, such as: carpets, loudspeakers, mosque clocks, towers and pulpits. Even the implementation of mosque management has not been so evenly distributed so that it has not been accompanied by social welfare efforts for the community. The purpose of this service is to find out the condition of the social welfare of the community. Community Service is the third dharma of higher education tri dharma. Meanwhile, in analyzing the data, the writer uses data collection, data reduction, data presentation, and verification. The results of this service showed that the condition of community welfare is experiencing stability with the implementation of programs carried out by mosque administrators to help community welfare, then the implementation of mosque management in an effort to improve community social welfare is by having a clear and transparent management function which makes the function of the mosque better.
