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

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 article reports the results of a study into the efficiency of refrigeration systems. The efficiency of the refrigerant-based cooling system is a significant issue due to its connection to global warming. Vapour compression refrigeration (VCR) systems utilise the inverted Rankine cycle to provide cooling process. Existing systems are evaluated and controlled, and their efficacy is either maintained or improved. A VCR device explores evaporator load variations at five different rpm levels as test equipment for measuring the performance coefficient of R32 refrigerant. A 365-watt compressor drives the VCR system. R32 is a more eco-friendly alternative to R22 as a refrigerant. Interpolation and extrapolation were utilized and adapted to convert the system's experimental enthalpy value to total performance. Genetron was chosen to evaluate enthalpy alongside other factors, such as VCR performance. Genetron properties was used to double-check the experiment's findings. The highest CoP was found and evaluated at a speed of 400 rpm (1st level) with the result about 3.17. The lowest value for CoP was found and achieved at the maximum attainable rpm, which was 2.53. The association between CoP and fan speed is inversely proportional during evaporator loading. Genetron properties software validation results produced an average CoP value of less than 10% compared to experimental data. In addition, this work significantly contributes to the study of VCR performance through the development of test devices for the provided VCR system

Abstract

Pengembangan proses manufaktur dilakukan secara masif untuk meningkatkan efisiensi proses produksi dan pemenuhan tuntutan produk yang semakin inovatif. Proses pemotongan memiliki fungsi penting pada bidang manufaktur dan dilakukan sebelum proses stamping. Penggunaan CNC laser cutting dapat meningkatkan kualitas pemotongan, dan waktu proses yang lebih baik. Tantangan utama dari proses pemotongan menggunakan CNC laser cutting adalah kualitas pemotongan yang relatif bervariasi antar satu material dengan material yang lain. Parameter yang terlalu banyak pada operasi laser cutting menyebabkan harus selalu ada penyesuaian untuk tiap proses pemotongan dan sangat bergantung pada keahliaan dari operator. Studi ini secara khusus fokus pada rekayasa parameter laser cutting untuk proses produksi dudukan spring coil. Tiga parameter utama dipilih yakni: peak power, cut speed dan gas pressure. Peak power yang digunakan adalah 80 & 100%, sedangkan cut speed yang digunakan adalah 1 & 2 m/menit dengan tekanan gas bervariasi antara 11, 13 dan 15 bar. Tiga jenis material digunakan yakni stainless steel 304 (SS), Cold Rolled Mild Steel Plates, Sheets and Strip (SPCC) dan Hot Rolled Mild Steel Plates, Sheets and Strip (SPHC). Terdapat 36 sampel yang diuji sesuai dengan kriteria yang ditetapkan. Hasil pengamatan dimensi menunjukkan parameter ideal untuk tiap material yang diproses. Untuk SS, parameter ideal diperoleh dengan cut speed 2 m/menit, peak power 100% dan tekanan gas 13 bar. Pada material SPCC parameter ideal adalah cut speed 1 m/menit, peak power 100% dan tekanan gas 15 bar. Terakhir untuk SPHC adalah cut speed 2 m/menit, peak power 100% dan tekanan gas 11 bar. Dimensi pemotongan untuk tiap jenis material menunjukkan nilai yang ideal untuk produk dudukan spring coil yang dihasilkan. Dengan demikian, rekayasa parameter proses laser cutting dapat dilakukan dengan mengacu kepada parameter tersebut.

Abstract

MPX5500DP is a sensor designed to measure how much air pressure is traveling in a channel or piping system. The MPX5500DP sensor has an analog output value that can be converted into a digital signal to display data on how much air pressure is being generated. By utilizing the MPX5500DP sensor the purpose of this study is to measure air pressure in HVAC systems with Micro SD data storage and IOT (Internet Of Things) based Web Browsers. The method used in implementing the MPX5500DP sensor is, selecting materials, making tools, installing sensors and testing. The test results obtained from Micro SD storage are the average air pressure value of 15.76 kPa. The IOT test produced an average air pressure of 15.67 kPa. At the time of testing, there were problems where data transmission was very slow so that for 30 minutes the test only received 14 air pressure data that were read on the Web Browser, namely ThingSpeak. However, the IOT test on an air pressure gauge using the MPX 5500DP sensor was successful. The success of the IOT system in monitoring HVAC air pressure can assist in monitoring the HVAC system in multi-storey buildings.
