Abstract

In Madiredo Village, which is located in Pujon District, Malang Regency, there are many business programs. The problem is that these efforts result in a wide range of waste, including up to 5 tons per day of residential waste and other corporate waste. The debris was gathered from the Bengkaras Hamlet, Madirero Village Reduce, Reuse, Recycle (TPST 3R) Integrated debris Management Site. However, a lot of plastic garbage has still leaked out of the packing. The objective is to create a press machine (press) with an electric motor so that packed plastic trash and levers (used when the power goes out) no longer require manual work. The process involves designing and producing waste press machines, particularly for cardboard, plastic trash, and old bottles. Use of the 2016 version of Solidworks for the simulation design. The lowest stress, 2.038 x 104 N/m2, and the highest Von Misses stress, 2.825 x 108 N/m2, are determined by the modeling findings. The biggest displacement or deflection is 1.737 x 10 mm, while the smallest displacement is 0 mm. The values of the strain range from 1.880 x 10-7 to a minimum of 6.00 x 10-4. Safety factor has a value greater than 1 A 1 horsepower AC motor is used in the press machine's construction. Three different distance stopper pressing variables—33 cm, 35 cm, and 37 cm—as well as various types of waste plastic bags, plastic bottles, and cartons/cardboard are used to test the pressing performance. The results show that pressing plastic trash at a distance from the pressing stopper of 37 cm, a mass of 167 kg, a time of 2.2 minutes, and a compressive force of 6546.4 N/m2 may pack or package well for garbage in plastic bags

Abstract

The role of solar panels is to transform solar energy into electrical energy. The process of monitoring solar panel output is still done in the traditional manner, which takes a lot of time and produces less reliable data. In order to solve this issue, a system that can track data produced by solar panels in real time and remotely via an application has been developed. With the help of the Internet of Things (IoT), this monitoring system, which makes use of a 20 WP solar panel, will show data in the form of readings of light intensity, voltage, current, and applications made with MIT App Inventor that use real-time databases on Firebase and the ESP32, and that are powered by DC power. Several tests were run on sending data to customers in this study while looking for the delay value. The solar panel's output voltage is measured against the greatest value for sunshine intensity, and output is also measured with and without a 12V DC lamp load on the battery. With an average time of 18.01 seconds, the data monitoring results were obtained to inform consumers. The highest value occurred at 12.00 WIB with an intensity of 54,588 lux and a solar panel output voltage of 20.01 volts. When the battery's output is measured without a load, it averages 12.56 volts, 0.02 amps, and 0.2 watts; when the battery's output is measured with a 12 volts direct current light load, it averages 11.98 volts, 0.40 amps, and 4.8 watts. Real-time monitoring of solar panel dc power is substantially facilitated by this monitoring method

Abstract

In Indonesia, flooding is frequently brought on by the issue of garbage in ditches. Plastic bottle garbage is one of the waste forms that is frequently found. Because of this, a machine to collect gutter bottle waste and raise the bottle waste from ditches must be made. The operator can use a gamepad to control this DC motor-driven equipment. A chain transmits the rotation of the DC motor to the engine driving wheel. A chain that has been transformed into a conveyor is used as part of the system for lifting trash from the gutter to the storage tanks. The wheel base can be manually shifted to change the wheel width from 80 cm to 120 cm. The machine has a success rate of 76.6% while lifting waste, and it can move forward or backward across the ditch at a speed of 0.041-0.042 m/s while transferring up to 3 spinning waste bottles. This device can significantly help with efforts to improve the gutter environment and lower the chance of flooding brought on by rubbish clogging.

Abstract

The aim of this research was to investigate the influence of catalyst on the flash point, viscosity, density, and iodine value of biodiesel. The raw material used in biodiesel production was waste cooking oil. The transesterification process was employed by reacting the catalyst and methanol, followed by mixing them with the waste cooking oil simultaneously. The catalyst concentration variations used in this study were 0.25% and 0.5%. The resulting transesterification mixture was left to settle for approximately 10 minutes. The biodiesel and glycerol were separated after settling, and the biodiesel was washed with distilled water at a temperature of 50°C and then evaporated at 100°C. The flash point test results for catalyst concentrations of 0.25% and 0.5% were 58°C and 48.5°C, respectively. The viscosity test results for catalyst concentrations of 0.25% and 0.5% were 4.567 x 10-6 m2/s and 4.625 x 10-6 m2/s, respectively. The density test results for catalyst concentrations of 0.25% and 0.5% were 889 kg/m3 and 888.3 kg/m3, respectively. The iodine value test results for catalyst concentrations of 0.25% and 0.5% were 112.2 g I2/100g and 114 g I2/100g, respectively. Based on the test data, the flash point, viscosity, density, and iodine value were obtained. The test results indicated that the flash point values from both experiments did not meet the biodiesel quality standards. However, the viscosity and density test results from both experiments met the biodiesel quality standards and were suitable for use. Regarding the iodine value test, the characteristics of the biodiesel from both experiments did not fully meet the biodiesel standard, although the results obtained were not significantly different from the quality standards set by the Ministry of Energy and Mineral Resources

Abstract

A screw compressor is one of the industrial machines needed for productivity and use in today's production. Industrial machines generally use pneumatic systems with the help of compressed air supplied by a compressor machine. The compressor working system must receive very special attention. Maintenance and prevention of damage to air screw compressor machines is very necessary, especially maintenance and prevention of damage to rotary screw air compressors. Problems that often occur with the shaft will result in reduced air supply flow or unstable air pressure resulting in disruption of the production line. The aim of this research was to discuss the vibration values produced against the rotor clearance from the ideal output on male and female screw compressor rotors using the frequency analysis method, taking the vibration values at the screw compressor housing point using an Accelerometer sensor and a Fast Fourier Transform (FFT) tool. The analyzer rotates at 1500 rpm in the X, Y and Z axes at each predetermined point. Research shows that the clearance is set at 0.03, 0.05 and 0.08. In this research, the high frequency sample values of 1x 25 Hz, 2x 50 Hz, and 3x 75 Hz often appear in each vibration data of 0.03 and 0.05, at the vibration frequency range value of 0.08 none appear. This shows the results that the ideal rotor clearance value is at a distance of 0.08 because there is no frequency graph of 1x, 2x, and 3x rpm at each point and axis on the end housing of the screw rotor compressor

Abstract

Corrosion has eroded the shell and head of the roll-off tank used to carry B3 waste. This influence will effect on the functioning of the waste containment tanks, as well as the general safety of the public. The goal of this study was to examine the viability of employing a roll off tank by completing a visual inspection and engineering calculations using ASME VIII and API 510 standards to determine the corrosion rate and remaining life in the roll-off tank. This study employs a quantitative approach. Tank design data was acquired using SA-240/G316L material with an initial shell and head thickness of 6 mm and an actual thickness of 5.45 mm shell and 5.50 mm head. The corrosion rate and remaining life analysis yielded a Thickness Required shell value of 4.33 mm and a head value of 4.33 mm, with a shell and head Corrosion Rate value of 0.04 mpy, a Maximum Allowable Working Pressure (MAWP) value of shell and head of 0.63 Bar, and a shell and head remaining life value of 28 years and 30 years, respectively. It may be established that the roll-off tank is still operationally viable. Maintenance and testing regularly to improve roll-off tank performance

Abstract

Flexibility comes from the cutting force generated when the workpiece and tool react and are moved to different areas of the scrap machine. The chisel will get damaged as a result. The material and cutting speed that are used can cause damage. Given this, further studies employing the vibration method are required to determine the ways in which material affects the speed at which scrap is chopped. PVC, iron, and aluminum 5052 were the materials used in this investigation. The cutting rotational speeds varied from 32 to 80 m/min. To measure vibration, the accelerometer is positioned along the x, y, and z axes. The measurement outputs of the accelerometer are connected to the FFT Analyzer, which performs analysis using Matlab. When comparing cutting speeds above or below 50 m/min, the research results indicate that the x-axis has the largest amplitude and the most form variants. The most widely used material is PVC, which is followed by iron and aluminum. This is because, unlike aluminum and iron, which have microstructures in the form of crystal grains, PVC is a thermoplastic polymer with a microstructure made of chain molecules. Because all of the cutting energy is used in the frictional action between the chip and the workpiece when the tool is being used, the high frequency is the result. As a result, the friction on the sliding plane is breaking up atomic or molecular bonds. Additionally, the cutting force exerts a significant amount of pressure on the tool's wearing active surface

Abstract

The Savonius vertical axis wind turbine is widely used because of its simple design and efficiency at low wind speeds. The next development is the mini multi-blade Savonius helical wind turbine. At this miniature size, the performance of a mini multi-blade helical Savonius turbine due to variations in the number of blades and its impact on the energy produced has not been investigated in depth. Therefore, adjustments to the size and number of blades need to be made to optimize the performance of this turbine. The research aims to obtain the performance of the Savonius type S wind turbine with 3 blades and 4 blades using the CFD (Computational Fluid Dynamics) method. The main dimensions of the simulation model are the shaft diameter of 0.008 m, the outer diameter of 0.24 m, the height of 0.4 m, and the number of blades 3 and 4. The inner diameter of the 3-blade turbine is 0.21 m while the inner diameter of the 4-blade turbine is also 0.21 m. Both turbine models are subjected to wind speeds of 4 m/s, 5 m/s, and 6 m/s. Based on the simulation results, a turbine with 4 blades has more optimal performance compared to the 3-blade type. At a wind speed of 6 m/s, the 4-blade Savonius helical turbine produces a rotation of 498,215 rpm and a maximum power of 6,129 watts. Meanwhile, the Savonius turbine with 3 blades at a wind speed of 6 m/s produces a rotation of 545,655 rpm and a maximum power of 4,390 watts. This difference in performance shows the importance of adjusting the number of blades in wind turbine design to achieve optimal efficiency. This research provides useful insights for the further development of mini helical Savonius wind turbines in various wind conditions

Abstract

R-22 refrigerant has been recognized as a major cause of climate change and ozone layer depletion, leading to increased interest in finding more environmentally friendly alternatives. Two alternatives being considered are R-134a and R-290. The main objective of this research is to compare the Coefficient of Performance (CoP) performance of split ACs using three types of refrigerants, namely R-22, R-134a, and R-290, taking into account the environmental impact and operational efficiency. The research method involved retrofitting a 1 PK split AC which initially used R-22 with three different types of refrigerant as an experiment. The research process includes test equipment design, equipment installation, and feasibility testing before carrying out experimental testing. Tests were carried out with variations in refrigerant charging pressure of 70 psi, 75 psi, 80 psi, 85 psi, and 90 psi. The research results showed that the largest COP was found in the R-290 refrigerant, reaching a value of 0.86 at a filling pressure of 90 Psi. The largest COP value for R-22 was also found at a filling pressure of 90 psi, namely 0.66. Meanwhile, R-134a achieved the highest COP value at a filling pressure of 90 psi, with a value of 0.57 at a variation of refrigerant filling pressure of 90 Psi. In conclusion, this study provides better insight into the efficiency and environmental impact of the three types of refrigerants discussed. It also provides a useful information basis for the selection of suitable refrigerants in split air conditioning systems, with the aim of environmental conservation and achieving optimal performance
