Compost can occur by itself through natural processes, but the process takes a long time. The process of organic materials such as grass into compost can be accelerated by the process of being chopped into small pieces first, then mixed with microorganisms. The process of cutting or chopping grass will be faster if done with a chopper machine. The size of the grass's chops significantly affects the composting process. The smaller of the chops, the composting process will be faster because decomposing bacteria touch the surface area. The research aims to study the effect of the inclination and the number of chopper blades on the grass chopper machine's performance. One component that affects the results of a chopper is a blade. The initial stage of this study is to build a prototype chopper with blades made from high-speed steel (HSS). The process of data collection is based on the different blade inclinations, i.e., 0o, 5o, and 10o to the horizontal axis, and the different number of blades, i.e., 2, 3, and 4 with 3,339 rpm motor rotation. The chopping capacity of the machine is measured based on the weight and length of the chops. The results of testing with the same blade inclination and the different number of blades show that with four blades, the weight of the chops is greater, and the percentage of chops with lengths > 1.5 cm is lower. This happens because the frequency of cutting is greater. While the same number of blades, but with different inclination, the weight and percentage of chops with lengths > 1.5 cm tend to be similar due to changes in the cutting platform.

One of the ideal geometric characteristics of a component is a smooth or rough surface. In practice, it is not possible to obtain a component with a smooth/rough surface. This is due to several factors, such as the human factor (operator) and the factors of the machines used to make it. However, with technological advancements, the growing apparatus capable of forming surface components with a high degree of fineness/roughness, according to the standard measures applicable in metrology, is advanced by geometric measurement experts through research experience. Fineness level/roughness of a surface is very important role in the planning of a machine component, especially concerning the problem of lubrication friction, wear and tear, resistance to fatigue and so on. Therefore, in the planning and manufacture must be considered first about which machine equipment should be used to make it and how much the cost must be incurred. In order for the process of manufacture, there is no significant deviation, then the characteristics of this surface should be understood by the planner even more by the operator. Communication of surface characteristics is usually done in engineering drawings. But to explain perfectly about the characteristics of a surface seems difficult. The research method is started by preparing instrument that is Milling Machine which is used to make surface roughness and Surface Roughness Tester is done 3 times test with variable speed of food which is different equal to 7,3; 13; 24.5 mm/put. With a speed of 102 rpm Rpm, and a depth of 0.4. Next, determine the material roughness level with Surface Roughness Tester. After all, done will get the data test results, followed by analysis and discussion so that will get final conclusion. From the research results obtained the following results: there is a difference in the level of roughness in each material with different feeding speed. The feed rate of 7.3 mm / put yielded 0.64 μ, 13 mm / put roughness generated 1.32 μ, 24.5 mm / put yielded 3.77 μ. The process of measuring the roughness of the material with the speed of feeding is slower, the smoother the surface roughness, the faster the speed of the feeding the more rough. The range of syrup result is also influenced by the speed of the food. The faster the movement of the range range the wider the surface roughness is the opposite.

One of the environmental issues to be addressed, particularly in the field of refrigeration and air conditioning, is the destruction of the ozone layer and the effects of global warming due to the use of environmentally inefficient refrigerants. In the field of Refrigeration and Air Conditioning, refrigerant as a cooling medium, plays an important role, and until now there is still the use of refrigerant materials that are not environmentally friendly, generally synthetic refrigerant. One alternative refrigerant replacement against the synthetic refrigerant is hydrocarbon refrigerant (HC). On the other hand, several ways can improve the performance of refrigeration system by lowering the temperature of liquid line using liquid to suction heat exchanger. In this study, a numerical simulation was conducted to examine the effect of using liquid to suction heat exchanger on the performance of a unitary air-conditioning system using hydrocarbon refrigerant as a coolant fluid. The results are, liquid to suction heat exchanger increase refrigeration effect by raising heat exchanger effectivity, the highest increase is about 7%. But the use of LSHX also rises up the compression work by increasing heat exchanger effectivity by 19%. So the Coefficient of performance (COP) and relative capacity index decrease by 5%. Decreasing performance is higher in the unit that operates at higher temperatures.

Ultra High Molecular Weight Polyethylene (UHMWPE) is a biomedical polymer applied for orthopedic as hip, knee, ankle and lumbar disc implants. The use of this material is common as a joint component paired with metallic biomaterials such as 316L stainless steel (SS 316L), cobalt chrome alloy (CoCr) dan titanium. This application has a wear problem. UHMWPE implants are commonly made with machining processes, i.e. lathe and milling. The effect of machining is the surface roughness of implant products. Polymer highly elastic in which would induce the deformation of surface asperities during loading and unloading. This phenomenon is determined with a parameter called elastic recovery. The magnitude of elastic recovery relates to the wear of the polymer. This research numerically investigated the effect of metallic biomaterial types on the UHMWPE elastic recoveries. Those metals are CoCr, SS 316L, and titanium. Two-dimensional surface asperity models were loaded with physiological gait loads of hip and knee. Results from computational works showed an insignificant difference of UHMWPE elastic recoveries penetrated by the studied metals. Elastic recovery due to SS 316L with knee gait load is 55.19%, equal to CoCr while other results due to titanium are slightly higher, 55.224%. The difference for all metals is only 0.06 %. Contact pressures are also equal, 38.96 MPa (CoCr), 38.98 MPa (316L and titanium).
