Abstract

The IoT applications in the agriculture industry are intertwined in many ways, creating a hybrid construct of traditional businesses with digital connectivity implementations. Strategic issues and principles on the assimilation of IoT solutions are prevail through time: investment costs, data interconnectivity, management and analysis, as well as data security. The agriculture industry is expected to be always alerted for the changes that may apply, with all the contemporary challenges and future directions responding to the situations, so it can reap the optimum use of the IoT connectivity.

Abstract

Elektroplating pada plastik berfungsi menambah sifat konduktif dan dekoratif. Plastik ABS memiliki tingkat keberhasilan untuk dilakukan elektroplating karena dapat dietsa secara kimiawi. Tujuan penelitian ini adalah mengetahui pengaruh temperatur dan arus listrik proses elektroplating krom terhadap ketebalan lapisan dan kekasaran permukaan. Proses elektroplating pada plastik ABS diawali dengan proses etching, proses metalisasi palladium, dan electrolessplating nikel. Variasi arus proses elektroplating krom yang dilakukan adalah 11 A, 16 A, dan 22 A sedangkan variasi temperatur adalah 55oC, 65oC, dan 75oC. Pengamatan hasil pelapisan meliputi pengamatan struktur mikro menggunakan mikroskop optic dan SEM, ketebalan lapisan, kekasaran permukaan dan kekerasan permukaan. Semakin besar arus proses elektroplating dapat meningkatkan kekasaran permukaan dan ketebalan lapisan. Proses elektroplating dengan arus 22 A menghasilkan kekasaran permukaan 0,493 µm dan ketebalan lapisan sebesar 60,61 µm. Peningkatan temperatur proses elektroplating sampai temperatur 75oC akan menurunkan nilai kekasaran permukaan sebesar 0,40 μm dan ketebalan lapisan sebesar 21,53 μm. Variasi arus dan temperatur proses elektroplating tidak banyak berpengaruh terhadap nilai kekerasan yang berkisar antara 111 - 114 shore-D. Electroplating on plastic serves to add conductive and decorative properties. ABS plastic has a high degree of success for electroplating because it can be chemically etched. The purpose of this study was to determine the effect of temperature and electric current on the chrome electroplating process on the thickness of the layer and surface roughness. The electroplating process on ABS plastic begins with the etching process, the palladium metallization process, and the nickel electroless-plating. The variation of the chromium electroplating process current is 11 A, 16 A, and 22 A while the temperature variation is 55oC, 65oC, and 75oC. Observation of coating results includes observation of microstructure using optical microscopy and SEM, layer thickness, surface roughness and surface hardness. Coating research results include observations of microstructure and SEM, layer thickness, surface roughness and surface hardness. The greater the current electroplating process can increase surface roughness, thickness of the layer. Electroplating process with a current of 22 A produces a surface roughness of 0.493 µm and a layer thickness of 60.61 µm. Increasing the temperature of the electroplating process to a temperature of 75oC will reduce the surface roughness value by 0.40 μm and the thickness of the layer by 21.53 μm. The variation of current and temperature of the electroplating process does not significantly affect the hardness values ranging from 111 - 114 shore-D.

Abstract

Energi surya masih menjadi harapan besar dalam menggantikan energi fosil, karena potensinya, kemudahan dalam memperolehnya serta ramah terhadap lingkungan. Konversi energi surya menjadi energi termal atau energi listrik bukan akhir dari pemanfaatan energi surya dalam kehidupan. Dengan media dua konverter energi yakni sel surya dan termoelektrik energi surya dapat dimanfaatkan untuk membuat sistem pendingin ruang. Model ruang pendingin dapat dibuat dari kotak sederhana sampai ruangan dalam bangunan. Adapun yang ingin dicapai penelitian ini untuk mendapatkan sebanyak mungkin penyerapan kalor dari ruang di bawahnya dan mendapatkan temperatur terendah. Metode yang digunakan dalam penelitian ini adalah eksperimental. Pada model ruang pendingin bagian atasnya ditempatkan sel surya dan termoelektrik yang diberi ruang pembuangan panas dari termoelektrik. Susunan sistem pendingin terdiri dari pendingin termoelektrik dan heatsink sebagai penyerap kalor. Penelitian ini menghasilkan capaian kinerja model ruang pendingin dengan nilai CoP sebesar 0,989. Sementara temperatur terendah yang dicapai oleh model ruang pendingin sebesar 25,60 oC.

Abstract

Energy are the most important part of human life, every activity in human life is dependent on energy consumption. Humans are now using fossil fuel energy sources on a large scale so that fuel (fuel oil) is running low and alternative energy is needed. Hydrogen gas is an alternative energy that can replace fossil energy sources by using the electrolysis process in dry cell generators. The research aims to determine the material with the highest production and highest efficiency in the electrolysis process. This study used an experimental method by comparing stainless steel material with graphite sheets. From the results of the study it was concluded that the highest production rate was obtained for the variation of stainless steel 304 plate material at a time variation of 30 seconds with a result of 0.013333 l/s and the lowest variation for graphite sheets. at a time variation of 90 seconds with a result of 0.002222 l/s. The highest efficiency was obtained from variations in Stainless steel material with a time of 30 seconds reaching an efficiency of 45.19% and the lowest was obtained from variations of Graphite sheet with a time variation of only 7.53%.

Abstract

The tank car is a closed storage area or tank designed to contain the liquid as a gas or liquid at a different pressure than the ambient pressure. Chemical reactions with the fluid inside a car's tank or physical phenomena the fluid encounters can cause instantaneous changes in the condition of the tank, resulting in occasional cracking or leaking. This research aims to determine how the design shape of a 5000-liter tank affects surface pressure. The method utilized is the finite element method based on computer-aided engineering (CAE) with the software Ansys Workbench Student Version. The results demonstrated that the maximal stress value and total deformation of the Model 2 tank were significantly different from those of the Model 1 and Model 3 tanks. The tank variation of the model is known to have the lowest stress value of 1.1309 MPa and the lowest deformation value of 0.0042421 mm. Therefore, the Model 2 tank variants are more recommended than the Models 1 and 3 for vehicles with a 5000-liter capacity.

Abstract

This study investigates the safety factor and stress in order to determine the utmost dynamic load the press machine frame can withstand. Dynamic loads occur because of the working mechanism of the press machine, which suppresses the brick components. Test simulation stress analysis using the computer program Inventor Professional Student 2023 with the finite element method in a material structure simulation test of a brick press machine frame with a dynamic load treatment the frame design model uses mild steel material with dimensions of 880 mm by 545 mm by 1200 mm. The variable loads are 700 kg, 1000 kg, and 1500kg. The simulation results show the displacement value at a load of 700 kg = 0,25 mm; 1000 kg = 0,36 mm; and 1500 kg = 0,54 mm. The von Mises stress value is 700 kg = 70,03 MPa; 1000 kg = 100,4 MPa; and 1500 kg = 150,9 MPa. The safety factor value is 700 kg = 2,96; 1000 kg = 2,06; and 1500 kg = 1,37. The simulation results show that the frame design of the brick press machine has a safety factor of 2,06 and can withstand a dynamic load of up to 1000 kg.
