Abstract

Panel surya merupakan komponen penting dari suatu sistem pembangkit listrik tenaga surya yang berfungsi mengkonversi cahaya matahari menjadi energi listrik DC. Arus listrik yang dihasilkan oleh panel surya dapat dialirkan ke baterai sebagai tempat penyimpanan listrik. Intensitas cahaya matahari dan temperatur lingkungan yang berbeda di setiap wilayah serta kenaikan temperatur kerja panel surya dapat mempengaruhi efisiensi panel surya. Pengujian performansi panel surya diperlukan untuk mengetahui efisiensi konversi energi cahaya matahari menjadi listrik DC. Pengujian performansi panel surya telah dilakukan di kampus IV Universitas Pasundan Bandung dengan menggunakan panel surya tipe polycristalline yang berkapasitas 100Wp. Pengukuran dilakukan selama 30 hari menggunakan sistem data akuisisi. Besaran yang diukur adalah intensitas cahaya matahari, temperatur, tegangan dan arus yang keluar dari panel surya secara realtime. Beban yang digunakan untuk menerima suplai tegangan dan arus dari panel surya adalah baterai (Accu). Hasil pada pengujian menunjukkan bahwa panel surya yang diuji memilki efisiensi sebesar 11.4%. Kinerja ini lebih rendah 5.5% dari kinerja panel surya yang diukur pada STC. Besar daya keluaran tertinggi mencapai 63.1 W.

Abstract

This study focuses on plastic welding, a technique that employs polypropylene plastic material in 3600-litre reservoir applications. The liquid pressure within it causes hydrostatic pressure in the reservoir. The pressure in the reservoir is approximately 0.01 N/mm2. This study aimed to determine how frequently polypropylene joints leak or sustain damage as a result of welding. Hot gas welding (HGW) with a v-groove connection type is employed (v-grove). Specimens of polypropylene were prepared in accordance with ASTM D638-I. In this study, the input parameters were chosen by varying the welding position and the machine's setting temperature. The results indicated that the required welding temperature for 5 mm-thick polypropylene plastic ranged between 220 and 280 degrees Celsius. In the tensile test on samples S1, S2, and S3, the average decrease in tensile strength of the three test objects was 13.84 N/mm2, 15.98 N/mm2, and 15.21 N/mm2, respectively

Abstract

A 3D printer is the result of the development of automated machining technology, which progresses from the creation of a design to the printing of a product with a complex shape and high precision for optimal printing results. The 3D printer design process begins with the creation of a design to determine the machine's dimensions, followed by the determination of specifications for the required motors, the design of electrical wiring to select the specifications for a controller, and finally, the testing of the tools when 3D printing. The accuracy of 3D corexy printers and 3D Cartesian printers are compared experimentally in this study. The printing process using a 3D printer produced two values that exceeded the tolerance limit, one in each dimension's length and width, according to the results of ten tests. The printing process results in a 3D Printer Cartesian exceeding the tolerance limit by four values: one for the length dimension, two for the width dimension, and one for the height or depth dimension. The 3D Printer Corexy is consequently more precise than the 3D Printer Cartesian because it fails less frequently.

Abstract

Solar cells are becoming so common that every industry except PLN is already using them to produce alternative energy. The more solar cells used, the more light intensity meters are needed to calculate the amount of Illumination in a given area. This research entails constructing or implementing software, calculating the float's balance against the impact of waves, and determining how the float distributes load using the Archimedes principle. Electrical construction and chassis buoyancy are included in the design. When the density of water is greater than the density of the object, namely > objects (997 kg/m3 > 46.73 kg/m3), the variables obtained are the total weight of the buoy of 5,044 kg with the distribution of the object force of 49.43 N and the buoyant force of 1046.08 N. then this design produces the required buoyancy force when manufactured and used.

Abstract

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic shaping process using V-bending dies and SGCC galvanized steel sheet (JIS G 3302) material. During the bending process, the zinc layer on the surface of the galvanized steel must not be damaged. The zinc coating on galvanized sheet steel will affect the material forming process (metal forming process). This study employed an experimental design with four input variables: die opening L (mm), punch angle (punch engel), punch speed (punch speed), and bending force (force bending). The input factors for the experiment are 35 mm opening, 40o punch angle, 30 mm/minute punch speed, and 7500 N bending force. In the die opening setting conditions, the maximum spring-back angle is 35 mm, the punch angle is 40 °, the punch speed is 30 mm/minute, and the bending force is 6500 N. The average minimum and maximum spring-back angles in this condition are 0.71o and 4.08o, respectively. The bending force is 7000 N, the punch angle is 50 °, the punch speed is 40 mm/minute, and the minimum spring-go angle is 30o. In die opening parameters, the maximum spring-go angle achieved is 35o, the punch angle is 60o, the punch speed is 50 mm/minute, and the bending force is 700 N. The average minimum and maximum spring-go angles are 1.90o and 6.23o, respectively.

Abstract

Springback is a phenomenon that frequently occurs in bending processes and is detrimental to the manufacturing industry. Typical disadvantages include the incompatibility of the product's final dimensions and the need for additional processing. Indeed, these must also incur additional expenses and result in the inefficient production process flow. Consequently, the analysis of springback is attracted to studies to obtain a bending product that meets expectations. This study examined the springback phenomena on 60 mm x 19 mm x 2 mm aluminium alloy 6063-T5 materials using V-bending processes and approximately 40°, 50°, and 60° punch angles. This study also utilized the die opening and bending force variables, 35 mm and 2500 N, respectively. It was anticipated that these procedures would produce a 6063-T5 aluminium alloy with a bending angle of approximately 90 degrees. The results indicate that the bending angles produced by these processes with the various punch angles are 91.50°, 91.42°, and 91.67°, respectively. It indicates that the excess bending angle was referred to as springback. Consequently, a bending angle of approximately 90° can be obtained on aluminium alloy 6063-T5 using V-bending processes with the set parameters of die opening in 35 mm and bending force in 2500 N, in addition to the punch angle that was reduced based on the known springback value. In addition, it is anticipated that this result will contribute to the development of the manufacturing industry, particularly the aluminium alloy 6063-T5 materials industry, or serve as a reference for other relevant studies

Abstract

Computerized numerical control (CNC) is one example of advances in automated machine technology. CNC can fulfil high precision and complex product specifications. Industrial CNC milling is still expensive regarding the hardware and software required to operate it. As a result, CNC milling machines are only used by large companies, with only a few mid-sized industries using them. It makes it impossible for medium enterprises to compete with large industries in terms of quality and output. This research aims to develop a CNC that uses an offline Wi-Fi controller based on ESP32 as an application that supports CNC machine work processes for use in small and medium enterprises. In an experiment, the precision of a CNC milling machine equipped with a sliding mode controller (SMC) controller was compared with that of a CNC machine equipped with an ESP-32 Wi-Fi controller. The CNC milling process with SMC control exceeds the tolerance limits in three dimensions based on the results of ten tests, namely length, width, and height or depth. Six values, two in each dimension of length, width, and height or depth, exceeded tolerance limits due to the CNC milling machine's ESP32 Wi-Fi control. Therefore, the CNC with SMC control is more accurate than the ESP32 Wi-Fi control because there are fewer failures with the former. This research has been carried out and provides input for the implementation of SMC, which can be considered in the CNC milling process.

Abstract

Indonesia produced about 31.2 million metric tons of garbage in 2021. Roughly 87.1% of the total waste is comprised-evaluated of plastic waste. Plastic waste takes a very long time to break down in the environment. It took decades for trash made of plastic to decompose. Disorganized waste management at the landfill is a significant source of plastics-related problems. In order to reuse plastic garbage, it must be crushed up first before the recycling process. The primary objective of the design process for the crushing plastic machine used to shred plastic waste was to maximize productivity. The design of the machine that crushes plastic waste was created and prepared with the help of computer-aided design (CAD) and computer-aided manufacturing (CAM) software. One thousand and zero millimeters in length, three hundred and twenty millimeters in width, and twelve hundred and sixty millimeters in height describe this machine for chopping up plastic trash. In terms of crushing time and capacity, variations in the rotational speed of 1000, 1100, and 1200 blades in revolution per minute were optimal. The optimal crushing time for 2 kg-HDPE plastic waste was 37 seconds at 1200 revolutions per minute, followed by 1100 revolutions per minute; 2 kg-HDPE plastic waste was crushed and evaluated. HDPE plastic wastes have typically crushed faster in less time than PET plastic wastes. It has been evaluated and validated for any setting variation operation involving the crushing speed. Three kilograms of HDPE plastic waste yielded an optimum crushing capacity of 194.4 kg/hour at 1200 revolutions per minute. Next, at 1200 revolutions per minute, 2 kg-HDPE plastic waste is crushed. HDPE plastic wastes are typically more effective to crush than PET plastic wastes, regardless of the crushing speed setting variation operations. As a result of this study, plastic waste is being put to better use, helping to cut down on overall plastic use in the plastic waste management
