Abstract

Some problems that often occur with electric motorbike batteries include overcharge, overdischarge and overheat. To avoid these problems, it is necessary to regulate or monitor the battery, which is called a Battery Management System (BMS). The BMS in this research is focused on the use of PSDKU Kediri electric motors. With this BMS design, it is hoped that it can be used as a reference in battery system management so that the battery lasts longer. In this study, 112 batteries were used, consisting of 14 series and 8 parallel. The voltage sensor circuit is made to determine the battery cell voltage so that overvoltage and undervoltage protection can be carried out. Measurements can be made using a multimeter by adjusting the reading position on the voltage. The maximum voltage produced is around 57.7 volts with a charging time of 7 hours

Abstract

Exhaust emissions are the residual combustion of fuel in the engine that is released through the engine exhaust system. Gasoline water pumps have emissions that have a negative impact on the environment. To overcome this problem, this research modified the fuel system from Pertalite fuel to LPG fuel. The purpose of fuel conversion is to reduce air pollution and prove that LPG fuel exhaust gas is better than Pertalite, so it is necessary to test exhaust gas emissions. Exhaust Gas Analizer test method, measure exhaust gas emission levels rpm 1,500, 2,000, 2,500, 3,000 and ground spark plug variations 1, 3, 4 include gas CO, HC, Duration of 60 seconds, record the emission levels of Pertalite and LPG fuels. The results of the analysis of exhaust emissions testing that have been carried out show that exhaust emissions from LPG fuel are not better than exhaust emissions from Pertalite fuel.

Abstract

This study examines the effect of fuel pump pressure and the number of injector holes on the performance of the Honda Vario 150cc motorbike. The current fuel system has evolved from a carburetor to an injection system to improve fuel efficiency. The injector plays a role in spraying fuel into the combustion chamber with the volume and discharge set by the ECU. This study aims to improve and compare engine performance with variations in the number of holes in the injectors and fuel pump pressure.The research method used is experimentation by measuring the power and torque of the engine. The results showed that the number of injector holes and fuel pump pressure had an influence on the power and torque of the motorcycle. The increased number of holes increases the power and torque potential. Increasing the fuel pump pressure also improves engine performance.At the top speed, the best combination is found in the fuel pump pressure of 2.5 bar with 6-hole injectors. The optimal combination of the number of holes and fuel pump pressure can increase the power and torque of the motor

Abstract

Hybrid Motor is one of the newest technologies being developed to reduce dependence on the use of fossil fuels by utilizing electrical energy as a source of propulsion. The working principle of this motor is to convert electrical energy into mechanical energy so that the vehicle can run. In the preparation of a Hybrid Motor there is one component called a BLDC (Brushless Direct Current) Motor, a BLDC motor is one of the main components in a Hyrid Motor which functions as a propulsion device. In moving the speed of the motor, of course, a device called a controller is needed. This controller utilizes a source of electrical energy from the battery to be able to operate and control the performance of the BLDC motor. The BLDC motor controller plays an important role in controlling the supply of electrical energy flowing to the motor to produce the desired rotation and torque. This supply of electrical energy is needed to operate the components in the BLDC motor controller so that it can control the performance of the BLDC motor. This research aims to analyze the effect of varying vehicle loads and speeds on the value of the supply voltage and electric current required by the controller. The research results show that an increase in vehicle load and speed causes a decrease in the value of the controller input voltage. As the load and speed increase, the voltage value at the controller input decreases as more energy is applied to the motor coils to produce the required torque. Then the value of the controller input current has increased because to produce torque that is in accordance with the amount of load and increased vehicle speed, the current flowing to the motor needs to be increased. This shows that there is a relationship between the increase in load and vehicle speed on the value of the input voltage and current of the controller

Abstract

Natural cooling analysis with heat pipes is very important in cooling systems in rectifier components because their effectiveness can be influenced by a number of factors that need to be considered in their design and implementation. Here are some reasons why analysis is necessary. The design of thermal systems that use natural cooling with heat pipes must be analyzed to ensure that the heat pipes can handle the heat load generated by electronic components or other devices. This involves consideration of the size, shape, and heat distribution of heat pipes. The effectiveness of natural cooling can be affected by the operational environment in which heat pipes are used. Variables such as ambient temperature, humidity, and atmospheric pressure can affect the performance of heat pipes. This analysis helps adjust the design to match anticipated operational conditions.

Abstract

Efforts are made to improve the efficiency of waste transportation at TPS by making a belt conveyor machine. Problems on the part of the machine made of steel that is contaminated with garbage water (leachate) so that it can cause corrosion. To slow down the occurrence of corrosion, painting is done on all parts of the belt conveyor machine, especially on parts of the machine made of steel.  This research was conducted by immersing ST-37 steel (as the material of the conveyor belt machine parts made of steel) into the leachate solution with variations in waste residue leachate temperature with 35 ℃, 45 ℃, and 55 ℃ and iron paint thickness with variations of 15μm, 25μm, and 40μm. The corrosion rate was tested using the weightloss method. The corrosion rate study lasted for 5 weeks at the Malang State Polytechnic Materials Test Lab. The results showed that changes in waste residue leachate temperature affect the corrosion rate of steel, namely the higher the temperature, the higher the corrosion rate value. The variation of paint thickness on the steel as a coating also has a significant effect on the corrosion rate, the thicker the paint, the slower the corrosion rate. The interaction that occurs between temperature and paint thickness is directly proportional because the higher the temperature the higher the corrosion rate value but the value tends to decrease due to differences in paint thickness.

Abstract

Indonesia is one of the largest pineapple producing countries in the world. So far, pineapple leaves only become agricultural waste. One way to use pineapple leaves is by processing the fibers in pineapple leaves into a reinforcing material for composites. Composite is a combination of two or more materials that have a number of properties that cannot be possessed by each component, which are then arranged in a symmetrical combination to obtain certain properties. In this research, pineapple leaf fiber was used as a filler, while epoxy as a matrix is a resin that has good strength and durability. Pineapple leaf fiber – epoxy composite is an alternative material for making SNI helmets and car bumpers. This research aims to determine the effect of volume fraction and alkali treatment on the impact strength of composites made from pineapple leaf fiber - epoxy. The volume fraction used is 10%, 15%, 20%. Alkaline treatment is carried out by soaking pineapple leaf fibers for 1 hour in NaOH solution with NaOH levels of 5%, 10%, 15%. The impact strength test results show that a volume fraction of 10% with alkali treatment with a NaOH content of 15% produces the lowest average value of impact strength is 0.024 J/mm², while a volume fraction of 20% with alkali treatment with a NaOH content of 10% produces the highes average value of impact strength is 0.046 J/mm². Where these results meet the SNI helmet standard with an impact strength of 0.00972 J/mm², meeting the Japan Industrial Standard (JIS) A5905-2003 standard car bumper strength value of 0.02433 J/mm². This research concludes that a higher volume fraction produces a higher impact strength value, but this value decreases as the NaOH content of alkali treatment increases.

Abstract

Industrial development in Indonesia is currently taking place very rapidly, one of the industrial sectors that has an important role in increasing Indonesia's development is the manufacturing industry. Pahala Workshop is a service workshop engaged in the manufacturing industry that offers plate cutting services using a fiber laser cutting machine. The fiber laser cutting machine in Pahala Workshop is quite new and is starting to be in demand by many customers. For different types of materials, there are different cutting standards and parameters. The purpose of the study was to determine the effect of variations in cutting speed and oxygen pressure of fiber laser cutting machines on the surface roughness of 304 stainless steel material so as to determine the optimal parameters for the cutting process. The research method used a real experiment method with the independent variables of cutting speed (1400, 1700 and 2000 mm/min) and oxygen pressure (3, 4, 5, 6 and 7 Bar) and the dependent variable of surface roughness. The results showed that the lowest average value of surface roughness (Ra) of 5.087 µm was obtained at a cutting speed of 1400 mm/min and oxygen pressure of 7 Bar. While the highest average value of surface roughness (Ra) is 8.604 µm obtained at a cutting speed of 2000 mm/min and oxygen pressure of 3 Bar. Cutting speed and oxygen pressure affect surface roughness. The effect of cutting speed on the surface roughness value is that the faster the cutting speed, the shorter the cutting time so that the laser heat energy that hits the work plane area is not maximized. While the effect of auxiliary gas pressure (oxygen) on fiber laser cutting machine that hits the work plane area is getting uneven as the cutting speed increases.
