One way is by using ultrasonic imaging technique. In this research, a set up and test method for detecting and imaging blockages in pipes, and identifying the shape and position of the blockage using ultrasonic s…
ABSTRACT Wind turbines are windmills that are used to generate electricity. The basic principle works, namely converting the mechanical energy from the wind into rotational energy, then the rotation of the mill is used to rotate the generator, which in turn will generate electricity. Over time, many turbine innovations have been used. Innovation can be done by fixing existing deficiencies or ad…
ABSTRACT In the manufacture of latex finished goods, the water content that is too high in the latex greatly disrupts the vulcanization process. Therefore, some of the water first needs to be removed to obtain concentrated latex with a dry rubber content (KKK) of 55% -60%. Meanwhile, in the centrifugation method, the equipment investment costs are very expensive. Besides the high price, the ca…
ABSTRACT Tribology is the science that deals with friction, wear and lubrication on surfaces in the relative motion of objects. In machining mechanical contact is unavoidable regarding friction and wear. Mechanical contact that occurs will result in wear and tear between the two surfaces of the elements that touch and move. Friction is the loss of energy due to the occurrence of two objects th…
ABSTRACT This study aims to measure the value of Overall Equipment Effectiveness (OEE) and Failure Mode Effect Analysis (FMEA) of sterilizer machines to analyze the productivity of sterilizer machines at PTPN V Sei Galuh. Overall Equipment Effectiveness (OEE) is a method of measuring the effectiveness of using an equipment. By using the OEE method, companies can make improvements to parts that…
ABSTRACT In this research, a clothes dryer machine was studied using an Air Conditioner (AC) with a closed air cycle vapor compression system and using a room fan. This study aims to improve electrical energy efficiency, determine the performance of a clothes dryer, the speed of drying clothes and to compare the performance and the comparison of the rate of drying clothes with a room fan and n…
ABSTRACT The pin on disc type tribometer is a tribometer that works with a mechanism using pins and flat plate components that are partly in contact with each other. The disc will rotate and the pins will press against the surface of the disc due to the applied load. The disc-on-disc type tribometer is the contact that occurs between the roller element (solid cylinder) and the inner ring on the…
ABSTRACT One of the uses of biomass as fuel for households or industries is biomass pellets (Biopelets). Biopellets are a type of waste-based solid fuel that is smaller than briquettes. Biopellets or pellets derived from biomass are converted and can be used as fuel energy. In this research, the design of a vertical type biopellet printing machine was carried out and the structural analysis of…
ABSTRACT This final project aims to design a plastic type waste crushing machine which is expected to provide a solution to overcome the ever-increasing amount of waste. Plastic itself is a type of waste non-organic which is difficult to decompose. The method used in designing is Hatamura. The Hatamura method consists of several processes, namely requirements selection, specification selection…
ABSTRACT Pyrolysis is a process of thermochemical decomposition of solid materials into solid, liquid and gaseous forms through endothermic reactions. Therefore, the design of a pyrolysis reactor is very important so that the pyrolysis temperature can be reached so that products that can be used are formed, including charcoal, bio oil, and flammable gas.Modern human life depends on the energy …

Based on identifying problems when conducting interviews and direct observation to find out the network security system at SMK Labor. From the interview with the network controll…
ABSTRACT Coins are used in everyday life in various places such as in banks, supermarkets and automatic weighing machines. So, there was a basic need to automate coin counting and sorting. For these machines it is necessary to recognize coins very quickly and accurately, because further transaction processing depends on this recognition. Banks use money counting machines to count money. It can…
The need for hot water in everyday life is indispensable for industrial, hospital and household needs, due to the large demand for hot water, one idea emerged, namely a heat pump water heater assisted by solar energy which was designed which mainly consists of an evaporator panel with a surface area of 0.23 m2, a rotary compressor with an input power of 1/6 PK, an insulated water tank which has…
With the fulfillment of electricity needs, the standard of living of the community will increase, uneven population distribution and difficult access are one of the causes of an area not being electrified by PLN. One solution that can be used so that electricity needs are met is to utilize water energy in irrigation canals as an energy source. The obstacles faced in this process are the low…
ABSTRACT Advances in heavy equipment technology demand that maintenance on the unit is increasingly needed in order to improve the quality of work, so that the work carried out can be completed at the planned time. Periodic maintenance is very important for heavy equipment to prevent breakdowns. Breakdown is damage that occurs due to lack of maintenance on heavy equipment. one of the necessary…
ABSTRACT Atha Mapper 2150 take-off uses the hand launch method. The hand launch method is a method that utilizes the throwing force exerted by the launcher operator during takeoff. Take-off using the hand launch method has disadvantages, namely having a low level of safety, ejection strength, and ejection angles that vary each take-off so that it is at risk of causing a crash. This research ai…
