Abstract

Perlakuan panas merupakan salah satu alternatif untuk meningkatkan kualitas suatu produk baja, pada saat mengoperasikan excavator di pertambangan tidak menutup kemungkinan komponen yang rusak atau aus harus segera diganti karena akan menghambat kinerja alat berat tersebut, tidak jarang akibatnya. untuk ketersediaan spare part original sedikit atau harus dipesan terlebih dahulu, untuk mengatasi lamanya waktu penggantian tentunya pihak perusahaan akan mencari komponen non original yang banyak beredar dipasaran tentunya dari segi kualitas atau waktu pemakaian. menjadi lebih pendek dari komponen aslinya. Untuk meningkatkan kualitas komponen tersebut maka dilakukan proses heat treatment (quenching) untuk meningkatkan kualitas komponen tersebut. Perlakuan panas dilakukan mulai dari memanaskan spesimen hingga suhu yang sesuai divariasikan (800 °C, 850 °C dan 900 °C) kemudian ditahan di dalam oven selama 2 jam dan kemudian didinginkan secara cepat menggunakan air dan minyak, jenis pendinginan ini akan berpengaruh kekerasan dan mikro. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh temperatur quenching dan jenis pendinginan terhadap kekerasan dan mikrostruktur. Heat treatment is an alternative to improve the quality of a steel product, when operating an excavator in mining does not rule out the possibility of damaged or worn components which must be replaced immediately because it will hamper the performance of the heavy equipment, not infrequently due to the availability of spare the original part is a little or must be ordered in advance, to overcome the lengthy replacement time of course the company will look for non-original components that are circulating in the market of course in terms of quality or usage time to be shorter than the original components. To improve the quality of these components, a heat treatment (quenching) process is carried out to improve the quality of the components. Heat treatment carried out starting from heating the specimens to the appropriate temperature varied (800 °C, 850 °C and 900 °C) then held in the oven for 2 hours and then cooled quickly using water and oil, this type of cooling will affect the hardness and microstructure. The purpose of this study was to determine the effect of quenching temperature and type of cooling on hardness and microstructure.

Abstract

Gears are one of the engine components in the transmission system which functions to forward power from the drive shaft to the shaft to be moved. The speed ratio of the driving gear with the gear that is driven depends on the number of gears of each gear. Fault (Fracture) is the separation of a component or material into two or more parts, Ductile and brittle are the relative terms of certain faults, one type or another depending on the situation, the ductile fracture surface has its own characteristic in the macroscopic. The ductile fracture in the specimen leads to a point. The brittle fracture does not have plastic deformation. Decohesive rupture is a fault that occurs due to environmental reactions Autodesk Inventor is software development from its predecessor software in the CAD field, such as AutoCad and Mechanical Desktop. This software is made with various advantages with its predecessor software. The fracture on the planetary pinion gear Transmission in the pc300lc-7 excavator unit occurs because of the severe load that occurs at the operation, based on von misses analysis can be known (15,57 Mpa), principal stress (9,046 Mpa), and von misses stress with moment twisting (3,088 Mpa) is much smaller than the material elasticity limit of 689 MPa so that there is no stress concentration. The mechanism of failure occurs starting from the shock load in the material without any elastic deformation.

Abstract

Only a Part of the energy of sunlight is absorbed by solar panels during the day will be converted into electrical energy, the rest will be converted into thermal energy that conducted to the solar panel surface with high surface temperatures. High temperatures on the surface of solar panels can be combined as a trombe wall to produce a temperature gradient in the channel outlets or vents. The produced gradient temperature will create air flow velocity in the chamber and will increase due to the difference in density gradient. So heat in the room will be pushed out. This study will vary, the air gap width 3 cm, 4.5 cm and 6 cm by comparing the indoor temperature, humidity and electric power by using solar panels and without 450 tilted solar panel facing north. Room dimensions are 0.5x0.5x0.5 m, with solar panels 150x180x18 mm dimensions. Collecting data every 10 minutes from 07:00 until 19:00. The sensor used is LM35, DHT11, Voltage Sensor, and ACS712. Air condition obtained will be compared with the standard of comfort of air in the tropical building. Results obtained from the research is a widening gap Outlet Channel or ventilation in the room conditions will increase the temperature, the humidity, increase power and decrease the comfort in the room. Otherwise the narrow width of the gap or ventilation Outlet Channel it will lower the temperature, increase humidity, lower power and increased comfort in the room.

Abstract

The use of sand in the cfb boiler function as a coal burner which enters the combustion chamber. Sand in the combustion chamber is lined up and coal enters the combustion chamber. With the entry of coal into the furnace fluidization occurs, where the heat in the sand burns coal that hovers, so that the heat that arises is used to heat the water in the boiler tubes. The remaining coal combustion (ash) wil float/fly inhaled by IDF air. Sand movement is expeted to only always bubbling up ang down in the furnace area only so that complete combustion occurs and the boiler is reliable. Because the bubbling is influenced by air pressure, coal quality, which can cause friction between material (sand and coal) and refractory giving rise to abrasives on refractory. If refractory is abrasive it can cause abrasive on the tube water wall boilers, tube cyclones so that boiler performance will decrease.The use of sand that is not clear is one of the causes of refractory damage in cfb type boilers. So that the cfb boiler remains reliable, the use of sand must be in accordance with the type and size according to the particular boiler.

Abstract

One of the problems contained in biogas is carbon dioxide that can reduce the burning calorific value of biogas. It is necessary to purify. This research aims to reduce the levels of carbon dioxide in the biogas. This research was conduct with passing biogas from sanitary landfills to biogas purification insulators containing charcoal adsorption media. After the adsorption process, the biogas is continued and collected in the tube until the pressure reaches 2 bar and then tested the carbon dioxide level bypassing biogas to the chamber for carbon dioxide reading using CO2 analyzer. The result of reduction of carbon dioxide from biogas testing without purification was 13955,03 ppm and after purified by coconut shell charcoal decreased to 8713,78 ppm with effectivity purification equal to 37,56% and density of 0,688 gr/cm3, with American Charcoal decreased to 7399,41 ppm with the effectiveness of purification by 46.98% and density of 0,817 gr/cm3, with laban wood charcoal decreased to 11310.07 ppm with the effectiveness of purification of 18.95% and density of 0,448 gr/cm3 and with Glam wood charcoal decreased to 12867.84 ppm with the effectiveness of purification of 7.79% and density of 0,446 gr/cm3. So that the effectiveness of purification of the highest biogas is by using American Charcoal with the absorption of 46,98% and has the highest density value of 0,817 gr/cm3, for the magnitude value of charcoal density is directly proportional to the magnitude absorption of carbon dioxide and also related with the magnitude surface area, where the higher the surface area then, the greater the adsorption capacity to carbon dioxide.
