Mixing process use to mix liquid, viscous and granular materials. One of the common mixing devices is a vertical stirred mixer which uses a tank and a vertical shaft that rotate mixing blades. This research is done to get the effect of the blade’s number and angle inclination due to mixing performance. Mixing performance is defined as stretching and folding. The research is done by experiment. The blade’s number varies as 2, 3 and 4 blades. Blade’s inclination is varied as 90o, 80o, 70o and 60o. The blades are rotated 10 rpm. A cylinder with 18 cm diameter and 12 cm height use as mixing tank. White wall paint is used as mixing material. Black wall paint uses a tracker. Mixing processes are observed by a camera on top of the mixer. The mixing processes are arranged for 2 mixer shaft rotations. Video data are captured frame by frame and analyzed using image software. The result shows that blade’s number and angle inclination have an effect due to mixing performance. Blade’s number tends to decrease stretching and folding. Blade’s angle inclination also tends to decrease stretching and folding. Keywords: vertical stirred mixer, blade's inclination, stretching, folding

Annealing is a heat treatment process for the softening metallic materials, especially plain carbon steels. Based on the case study was found that thrust washer differential on the dump truck unit-machine model CWB6BLLDN2 fell up failure. Failure of the component was caused by the impact of gear differential on the differential case. The cracking of thrust washer was affected by the characteristic of materials which low resistance to impact load. Variation temperatures of annealing process are used by 825 °C, 875 °C, 925 °C, and 975 °C. Furthermore, a cooling method that been used is cooling on the furnace. Hardness test is used by Vickers hardness test with an indentation load of 200 kgf, and indentation time of 5 s. Cross section of the microstructure is examined by optical microscope. Based on the hardness test, the hardness is decreased by increasing of annealing temperature. Observation of microstructure shown changes on microstructure that been caused by increasing of annealing temperature. Keywords: Annealing, Hardness, Microstructure, Thrust washer differential

Automatic Audio Frequency Foliar Fertilization is a technology that improves between the nutrients performed on plant leaves by giving the sensation of sound waves in plants. Automatic Audio Frequency Foliar Fertilization is technology device leaf fertilizer integrated with Sound waves which will run automatically, more practical and compatible. This technology device consists of two main devices of active speakers that will issue a sound with a certain frequency and sprayer fertilizer. The results of the tests that have been done to produce the sound frequency between 1200 Hz up to 1600 Hz with average noise of 5%, with the debit of nutrient spraying for the plant of 96 ml per 30 seconds. Giving exposure treatment Wave The sound of classical music with the provision of nutrients in mustard plants by Automatic Audio Frequency Foliar Fertilization gives a real effect on the growth of the average height of the plant is 2.14 cm per 2 days.

Cracks during the quench process are a common problem. There are several observational parameters in the heat treatment process to succeed, namely the chemical composition of steel and its hardness, the geometry of the components, mechanical handling, the type of cooling fluid, the temperature of the cooling fluid, the conditions of the coolant, the circulation of the cooling media. In mass production, for example, bolt production in the quench process is more dominant in smaller diameters than As Bar compared to larger diameters. In this study, mechanical properties such as hardness, physical properties such as microstructure and cracking were considered as a function of the quenching conditions of AISI 1040 steel with a diameter of 25mm after hardening process at 850oC with the influence of quenchant concentration variations investigated. The microstructure of as-quench martensite and its development during the Hardening process is observed. The results showed changes in hardness and microstructure as well as cracks that occurred from specimens due to the hardening process on Quenchant Variation Key Words: Hardness, Heat Treatment, Quench, Quench Crack, Quenchant

Wind energy can be used as an electric energy generator, known as a Bayu Power Plant (PLTB). The PLTB component consists of wind turbines, generators, and batteries. The efficiency of the generator is influenced by the loading system on the power plant, which includes the use of data logger and controller components. The study aimed to find out the efficiency of the 12 Slot 8 Pole generator. The research method uses a MagNet Software simulation, with variables: in the form of R = 15 resistance and rotor rotation n = 1000 - 10,000 rpm. The results of the study show that the efficiency of the generator and the circuit starts to stabilize at rotor rotation n = 3000 rpm; highest efficiency when rotor rotation n = 9000 rpm with efficiency ηmax = 90,04614%; average efficiency ηav = 88.867%.
