Abstract

The process of making liquid soap from citronella oil is an interesting thing to know. This study aims to design, create, test and analyze the time and rpm rotation of the most efficient liquid soap mixer machine. Soap is an alkaline local salt (usually a potassium salt) of fatty acids, mainly containing C16 salt (palmitic acid) and C18 (stearic acid) but can also contain several carboxylates with lower atomic weights (Fessenden, 1994 and Ketaren, 1986). Traditionally, lemongrass is used as a flavor generator in food, drinks and traditional medicine (Wijayakusumah, 2002). Fragrant lemongrass is also used as a flavor generator used in spicy sauce, fried chili sauce, chili paste and fish sauce (Oyen, 1999). Data collection observed were device capacity, yield. From the results of the study, the effective capacity of the equipment was 397.1 L / hr. Keywords: liquid soap, citronella oil, effective capacity of the tool, yield.

Abstract

Pembentukan logam masuk dalam sebuah kelompok besar dari proses-proses manufaktur. Pembentukan logam menggunakan deformasi plastis untuk mengubah bentuk benda kerja. Deformasi atau perubahan bentuk dihasilkan dari penggunaan tool yang biasanya disebut die (cetakan). Cetakan tersebut memberikan tegangan yang melebihi kekuatan yield logam (plastis). Logam selanjutnya berubah bentuk menjadi bentuk yang sesuai dengan geometri cetakan. Pembetukan flens pada lubang disebut hole-flanging. Hal ini dimaksudkan untuk memperkuat bagian tepi dari lubang atau untuk tujuan membuat ulir. Untuk pelat logam yang tipis proses ini bisa dibuat bersamaan dengan proses piercing. Proses hole-flanging ini berfungsi untuk menyediakan luasan pengikatan pada sambungan-sambung pipa. Proses hole-flanging ini kemudian dikembangkan dengan metode bertahap yang menggunakan cetakan yang sangat sederhana. Proses pembentukan ini disebut dengan incremental hole-flanging. Pada pembuatan flens untuk percabangan maupun pengikatan pada lingkungan kerja yang tertutup, proses hole-flanging konvensional tidak mampu dilakukan dengan prinsip pembentukan ke dalam. Proses pembuatan flens untuk kasus seperti ini digunakan metode incremental backward hole-flanging. Pada penelitian ini akan dianalisa karakter deformasi dari benda kerja alumunium dengan metode incremental backward hole-flanging terhadap laju pembentukan. Dimana mesinyang digunakan pada penelitian ini adalah mesin CNC 3-axis dengan parameter laju pembentukan sebesar 500, 1000, 1500, dan 2000 mm/min.

Abstract

The stability of the vehicle / motorbike is also determined by the suspension. Usually the suspension on the motor is installed right-left symmetrically. This is so that the vehicle load is evenly distributed if there is a shock / sudden load. But development and need negate each other. Currently, the development of automatic motorbikes is quite rapid. This motorbike is designed to be sleek and nimble and easy to maintain. Therefore, the rear suspension of the automatic motorbike is installed on only one side. And this usually occurs during sharp turns and high speeds and if you go through uneven roads. For this reason, it is necessary to design the right suspension so that the vehicle can maintain stability even when turning or passing uneven roads. This instability is due to the large vibration of the vehicle. The objectives of this study are 1. To determine the effect of the size of the spring wire and the length of the mounting on the vibration frequency. 2. Find the diameter of the spring wire and the length of the mounting that will give a good vibration frequency. This study uses the Desaign Of Experiment method. Desaign factor 2, namely diameter of spring wire and length of muoting. Level 3 factor is 6 mm, 7 mm and 8 mm diameter. Mounting lengths of 30 mm, 35 mm and 40 mm. Data analysis using MINITAB program. From the analysis, it is found that 1. The diameter of the spring coil wire and the mounting has a significant effect on the vibration frequency of the automatic motor. 2. The best size for wire spring diameter for coil spring motor matic is 7 mm, while the thickness of the mounting is 37 mm. Keywords: Suspension, Motorcycle, Spring Wire.

Abstract

Heat absorb ability split AC is the most important factor in the cooling speed on room temperature. The rate of temperature drop is determined by many factors, including compressor power. Nowadays, there are many Split AC are produced that have low power (low Watt), so that research is needed to determine the cooling speed in a room. This study uses a low watt split AC with a power of 0.5 HP. The distance from the evaporator and the outside temperature are used as independent variables, while the rate of temperature reduction or cooling speed in the room is used as the dependent variable. The results showed that the distribution of room temperature and the rate of temperature reduction in the room varied based on the position of the distance to the location of the AC Split Low Watt. The lowest temperature and reduction rate in the room occurs at a distance of 2 m and 3 m in front of the AC location. The outside temperature or the temperature around the location of the AC condenser affects the temperature distribution at each distance in front of the AC. When the outside temperature is low, the temperature conditions at a distance of 1 m, 4 m, and 5 m have a significant difference. While the high outside temperature conditions, the temperature at a distance of 1 m, 4 m, and 5 m, namely the positions close to the wall, is almost the same.

Abstract

The renewable energy has a very important role in meeting energy needs. This is because the use of fuel for conventional power plants in the long term will deplete the dwindling resources of oil, gas and coal and can also cause environmental pollution. Solar panels based on 2N3055 transistors and Thermoelectric Cooler (TEC) are the basic materials for designing alternative power plants. In the manufacturing process, this solar panel utilizes electronic components that are capable of generating electrical energy (emf), so that it can be used as an appropriate technology to produce a solar panel that utilizes solar energy in the form of heat and solar radiation. The use of transistors 2N3055 and TEC proved to be more efficient in generating electrical energy, there was no significant decrease in voltage and current even though the weather was suddenly cloudy. The average voltage and current generated in this solar panel are 24.58 VDC and 2.72 Ampere DC.

Abstract

Composite is a material consisting of a mixture or combination of two or more materials, either micro or macro, where the properties of the material are different in shape and chemical composition from the original substance. In this study, the composite was tested to determine the tensile strength using simulation. Composite material modeling consists of carbon fiber as reinforcement and epoxy resin as the matrix. Then the composite material was given a uniaxial loading with a loading value of 50 N. By using variations in the orientation of the fiber angle 45ᵒ/90ᵒ/-45ᵒ, 45ᵒ/90ᵒ/-45ᵒ and 60ᵒ/45ᵒ/-60ᵒ. This study aimed to determine the effect of fiber angle orientation on tensile strength, maximum deformation and location of maximum stress on carbon fiber composites. The best composite design is the composite with fiber angle orientation of 45ᵒ/90ᵒ/-45ᵒ with a tensile stress value of 3.6 MPa and the smallest deformation of 0.0644 mm.

Abstract

The two most important parameters in vehicle vibration are the level of comfort and stability. To get the best value from that parameter, the vehicle suspension system is very important to reduce vibration due to road waves and keep the wheels attached to the road. This paper studied the effect of the type of suspension on the vibration of a one-wheeled vehicle in terms of comfort and stability. The type of suspension is related to the value of the spring stiffness and the damping. While the vehicle is modeled with one wheel in two degrees of freedom. The test is carried out by loading the vehicle including the mass of the vehicle and passengers for each type of suspension, namely soft, medium and hard. Vibration analysis was performed using Matlab Simulink to obtain the acceleration response and deflection response. The vibration response graph shows the comparison of the level of comfort and stability of the vehicle on the road profile modeled in step, impulse and sinusoidal functions. From the simulation results, it is found that the Soft and Medium Suspension can handle vibration very well, especially from the level of response speed for relatively flat roads. Meanwhile, the Hard type of suspension is very good at dampening vibrations for high bumpy roads.
