Abstract

Increasing levels of carbon dioxide (CO) in the atmosphere in highly populated countries is driving renewed interest in developing research and techniques to reduce global warming. The abundance of corn silk is a very important factor and needs to be considered when it comes to its utilization. Several studies have been conducted regarding the use of corn silk, namely as an ingredient for making low-fat, anti-obesity, anti-diabetic meatballs which are obtained from corn silk polysaccharides. However, the potential of corn silk as a raw material for fuel has not been studied. Therefore, it is important to conduct research to understand the potential of corn silk as a new and renewable energy source which is expected to become a long-term energy reserve. Thermogravimetric analysis of the characteristics and kinetics in the normal room temperature range of 900 oC under a nitrogen atmosphere at a heating rate of 40 oC/minute. The results show that the pyrolysis process of corn silk is divided into 3 stages related to the process of reducing the water content at a temperature of 65-130 °C, followed by the devolatilization stage at a temperature range of 216-506 oC and the last is a relatively slow decomposition up to 900 oC. The activation energy (Ea) in the active pyrolysis stage was calculated using the isoconventional fitting model using the Vyazovkin model. The resulting activation energy from the calculation of the Vyazovkin model is in the range of 215,522 kJ/mol each.

Based on the results and discussion, the frame material uses ASTM A36 steel with a square hollow stock profile measuring (30 × 30 × 1.2) mm. Welding is done by welding the butt joint, T joint and corner joint. The permissible stress value of the material is 176.72 N/mm2. The load on the heating chamber is 3,920 N/mm2, on the upper frame cover 1,263 N/mm2 and on the stepper motor 4,947 N/mm2. The stress value for the frame is 47N/mm2 (Mpa), the displacement value is 0.41mm, the safety factor value is 8.

Abstract

Continuously Variable Transmission (CVT) is an automatic transmission system with gear ratio shifts following engine speed controlled by the primary and secondary pulleys, as well as the V-belt that connects the two pulleys. The disadvantage of the CVT transmission system is that it often loses grip on the CVT clutch lining and the V-belt at low and high rotation so that research needs to be done so that the power from the engine to the wheels can be maximized. This study used an experimental method by changing the variation in the size of the V-belt and the groove angle on the clutch pads to find the best size for a 125 CC motorbike. The results showed that to get maximum results it is recommended to use a V-belt 803 x 19.0 mm with a CVT lining of 30° producing the highest power and a V-belt 840 x 21.8 mm with a CVT lining of 90° producing the highest torque

Abstract

Hacksaw is a saw that is used to cut metal objects such as iron. Hacksaws are still widely used for metal cutting processes because they have the advantage of not generating excessive heat during the cutting process which can affect the metal structure. Behind these advantages, cutting metal using a hacksaw manually is less efficient in time and the cutting results are less neat. The solution to this problem is to make a hacksaw with an electric motor drive. The design of this automatic hacksaw machine uses a drive in the form of an electric motor with a capacity of 0.5 HP. The output from the rotation of the electric motor is forwarded using pulleys and gears with a ratio of 12:1, and is continued using a slider to move the hacksaw blade back and forth. Reduction of rotation is intended to increase the cutting torque. The design of this hacksaw machine also adds a feature in the form of an automatic switch to stop the movement when the cut is complete. Based on the test results of the automatic hacksaw machine used for cutting carbon steel, the cutting capacity is 2.4 cm2/minute and the electric motor power calculation has a power capacity of 2.5 W/cm2. The results of cutting the material are also straight and neat without causing heat during the material cutting process.

Abstract

Corrosion is one of the things that occurs due to damage or degradation of metals due to a redox reaction between metals and various substances in their environment so that they can produce unwanted compounds. This corrosion is also often referred to as rusting. The process of this research was carried out by calculating the loss (weight loss) and analyzing the ratio of corrosion velocity, specimen changes, the ratio of fresh water and sea water and the ratio of specimens with coating and without coating. with a research time of 14 days. From the results of immersion analysis, comparison and calculation of specimens in the corrosion process yielded a value (mm/y), specimen 1 without coating corrosion value per year 0.37 (mm/y), specimen 2 without coating corrosion value per year 0.52 (mm/y ), specimen 1 with coating corrosion value per year 0.26 (mm/y), and specimen 2 with coating corrosion value per year 0.3 (mm/y). Overall, the research conducted on the corrosion of one of the four specimens, namely the specimen without coating, experienced a decrease in mass due to corrosion, from 54.09 g to 54.04 g. Uncoated specimens in the absence of protection have a higher corrosion rate

Abstract

This study aims to determine the catalytic effect of ZnO on the kinetics of the decomposition reaction of burning solid waste. ZnO catalyst was chosen because it has high mobility and reactivity. samples were prepared and randomly selected consisting of 12 types of inorganic waste and 10 types of organic waste. The research instrument uses (DTA) Differential Thermal Analysis proximate testing. From this test the data in the form of a mass decrease graph will be analyzed descriptively. The description of the data is displayed through the TG-DTG curve and the calculation of the activation energy (Ea) using the fitting model. the DTG curve identifies three peaks indicating the decomposition stages of the three components have different characteristics. The decomposed components are 1. lignocellulosic organic and low stability organic components, 2. Volatile substances from plastic components, 3. hydrocarbon residues and ash reformation. The combustion temperature increases in samples with high catalyst concentrations, but the burnout temperature decreases in samples with high catalyst concentrations. The DTA curve shows the increased reactivity of samples with high catalyst concentrations. Oxidative reactions which are exothermic/external heating increase in samples with high catalyst concentrations. The catalytic effect on the addition of zinc-oxide (ZnO) catalyst concentration to the components showed a decrease in the hydrocarbon component and an increase in the short chain hydrocarbon component. Increasing the concentration of zinc-oxide (ZnO) catalyst in the sample increases the activation energy. However, overall the addition of catalyst concentration in the combustion of organic-inorganic solid waste samples was able to reduce the activation energy at the end of the combustion reaction

Abstract

ECU is an electronic device for controlling electronic systems on motorcycles. Centrifugal clutch uses centrifugal force to connect the engine to the wheels. Selection of the right ECU and centrifugal clutch can improve engine performance. This study compares engine performance using different ECUs and centrifugal clutches on Honda Vario 150cc motorcycles. The research method uses experiments and data analysis. The results show that the use of a racing ECU produces the best power at 3500 rpm, which is 14.43 hp with standard clutch lining. Power increase of 1.53 hp from standard conditions. The best acceleration of 9.4 hp is achieved with a racing ECU and a modified clutch pad (7 cm long). At high speed, the highest power reaches 11.93 Hp at 7500 rpm with a modified clutch lining (length 7 cm). The best torque is 42.22 Nm at 1500 rpm with a racing ECU and modified clutch lining (7 cm long), an increase of 2.4 Nm from the standard 39.82 Nm..
