Drum shell (selongsong drum) secara garis besar terdiri dari 2 jenis, yaitu ply by ply shell dan solid shell. Penelitian ini ditujukan untuk proses pembuatan drum shell jenis ply by ply shell. Yang dimaksud dengan ply by ply adalah shell-nya terbuat dari kayu yang berlapis-lapis, seperti teak block atau triplek. Semakin banyak lapisannya maka suara yang dihasilkan semakin tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh temperatur cetakan dan lama pengempaan terhadap keteguhan rekat kayu lapis dan prosentase kerusakan kayu. Variabel bebas yang digunakan dalam penelitian ini adalah 3 variasi temperatur (85oC, 90oC, 95oC) dan 3 variasi lama pengempaan (2 jam, 3 jam dan 4 jam). Pengambilan data dilakukan dalam dua tahap yaitu data keteguhan rekat (KR) yang diperoleh dengan menggunakan metode pengujian kekuatan geser rekat yang dilakukan menurut standar ASTM D-905-49 tahun 1981 serta data prosentase kerusakan kayu (KK) yang dihitung menggunakan software Autocad 2007. Selanjutnya data dianalisa dan dibuat grafik yang akan digunakan untuk mengetahui pengaruh temperatur cetakan dan lama pengempaan terhadap keteguhan rekat dan prosentase kerusakan kayu. Hasil penelitian menunjukkan bahwa peningkatan temperatur cetakan dan lama pengempaan berbanding lurus dengan keteguhan rekat dan prosentase kerusakan kayu dan temperatur cetakan tidak berpengaruh terhadap kapasitas produksi sedangkan lama pengempaan berbanding terbalik dengan kapasitas produksi drum shell per hari. Dalam penelitian ini, nilai keteguhan rekat terbesar terjadi pada temperatur cetakan 90oC dan lama pengempaan 4 jam dengan nilai keteguhan rekat sebesar 23,25 kg/cm2. Dan nilai keteguhan rekat terkecil terjadi pada temperatur cetakan 85oC dan lama pengempaan 2 jam dengan nilai keteguhan rekat sebesar 19,25 kg/cm2.Kata kunci : Temperatur, Lama Pengempaan, Keteguhan Rekat, Kayu Lapis, Drum Shell.

Quenching is a cooling method of heat treatment for metal hardening. Quenching refers to the process of rapidly cooling metal parts from the austenitizing or solution treating temperature, typically from within the range of 815 to 970 Â°C for steel. The selection of a quenchant medium depends on the hardenability of the particular alloy, the section thickness and shape involved, and the cooling rates to achieve the desired microstructure. The liquid quenchants of oil is commonly used in industrial manufacture. But, oil is not environmental. The aim of this research research is to find new quenchant for change oil as quenchant to more environmental. Gel aloe vera is purposed for it. The material used in this study is AISI 1045 steel. Cooling curve and cooling rate is measured by finite element model, ANSYS APDL 14.5. True experimental is done to view microstructure and measure hardness of steel.

Fossil energy is a limited and non-renewable source of energy, therefore it is necessary to look for alternative energy solutions that are not available and can be updated. Another reason is to reduce the impact of pollution caused by the use of fossil energy. As we all know, the biggest source of pollution in the world comes from exhaust gas/fossil fuel emissions. These plants can convert wind energy into electrical energy using wind turbines or windmill. The electricity generation system using wind as an energy source is an alternative system that is very rapidly developing, considering that wind is an energy that is not limited in nature. The purpose of this study was tested using three blades, varying the diameter with a slope of 150, namely to determine the effect of blade diameter on the power produced by the turbine and the efficiency of the horizontal shaft wind turbine. The turbine power testing method is done manually by using 2 spring balance which is associated with the belt, v-belt, then the v-belt is associated with an 8 cm diameter pulley that is on the turbine shaft, the friction between the belt and the pulley is ignored. From the test results, the torque produced by the turbine is carried out in a certain rotation. Wind turbines made with blade blades 2 m, 2.40 m, 2.80 m with wind speeds of 4 m / s From the three turbine blade variables based on testing different turbine blade diameter the resulting power is different, from the test results it can be known the power generated by the power turbine can be seen that the highest power on the blade diameter is 2.40 m at 140 turns (rpm) with turbine power of 19.9606 watts, with an efficiency of 10,6263 % and the lowest in blade diameter 2m in rotation 120 ( rpm) with turbine power of 12.9374 watts, with an efficiency of 9,9579 %.

Used brake shoes are a component of a two-wheeled vehicle that has a type of aluminum material. Therefore, we can do remelting aluminum from brake shoes that can no longer be used for advanced application use and utilization of brake shoe waste which still has a sale value. This study aims to determine the best value or the one that approximates the fatigue limit endurance value of each loading variation given to the specimen and to determine the characteristics of the fracture surface from the differences in given loading. The research method used for fatigue testing is by using a literature study and direct observation or observation. Before doing the fatigue testing, first, do the tensile test to get the yield strength value where this value is used for the loading that will be given to the fatigue test, the loading variations are given for the fatigue test are 40%, 50%, and 60 % of the yield strength value. From the results of fatigue testing at a load of 60% with the stress of 100.2 MPa and a given load of 3.81 kg, it can be seen that the value of material fracture at 27,421 cycles and in the timeframe 00:18:16. Then at 50% loading with the stress of 83.5 MPa and a given load of 3.18 g, it can be seen that the fracture value of the material in the 51,659 cycles in the fracture period is 00:34:35. Then in the next test with a load of 40% and given the stress of 66.8 MPa and a load of 2.5 kg, it is known that the fracture value of the material in the 106,930 cycles in the fracture period reaches 01:11:17. From the test data, it can be concluded that the ratio between cycle and time with voltage is inversely proportional, that is, the smaller the voltage the greater the cycle and time obtained, and vice versa, the greater the voltage, the smaller the cycle and time will be obtained. Keywords: Used brake shoes, Aluminum, Remelting, load variation, fatigue test.

In the process of harvesting sugarcane at a sugar factory, the Sugarcane Harvester is a tractor used to harvest sugarcane equipped with a slicer knife. Nowadays slicers are still imported from abroad, and the availability is scarce and the price is still expensive. One of the efforts to find an alternative to the slicer is to use leaf springs by hardening the metal through a heat-treatment process. Namely the process of heating steel to temperatures above the critical area followed by rapid cooling called quenching. The purpose of this study was to determine the effect of holding time and the effect of cooling media on the hardness and impact strength of leaf springs and to determine the ideal holding time and the most optimal cooling media to increase the hardness and impact strength of leaf springs. As for the research method, the spring leaves were heat-treated with a temperature of 8500 C for 30 minutes and 60 minutes and then cooled using oil, saltwater, and water as media. The method used is observation, literature study, testing, and documentation. The results obtained from this study were at a temperature of 8500 C with a holding time of 30 minutes the best hardness value was 477 VHN and 0.42% increase, the best impact strength value was 0.03433 J / mm2 and 87.71% decrease, and the two cooling media, namely oil. At a temperature of 8500C with a holding time of 60 minutes the best hardness value was 534 VHN and 12.42% increase, the best value of impact strength was 0.03203 J / mm2 and 88.53% decrease, and the two cooling media were oil as well. So that oil is the most optimal medium for changing the mechanical properties of the Sugarcane Harvester slicer because the oil can carry a carbon layer from the cooling process that takes place and the cooling rate of the oil is not too fast from the cooling media of brine and water because of its viscosity. Keywords: Holding Time, Cooling Media, Hardness, Impact Strength, Quenching, Leaf Spring, Slicer.
