Abstract

Turbine is a rotating machine that takes energy from a fluid flow. A water turbine is a machine that converts the potential energy of air into mechanical energy. Indonesia has many water areas such as rivers, streams, seas, and so on. Unfortunately, the development of new and renewable energy in Indonesia has not been maximized. Based on this, the team designed a turbine in a pipe called Tulipa. An innovation to exploit the potential of new and renewable energy. Tulipa utilizes the wastewater flow in the factory that is not used and then converts it back into electrical energy. The energy produced by Tulipa is 5,593 kW. The calculations in this study become the calculation of the strength of the rods and simulations. Tulipa was tested using mechanical analysis of each component. The analysis was performed using Fusion 360 software for mechanical simulation and ANSYS for CFD or Computational Fluid Dynamic simulation. Simulations were carried out to determine the value of static stress, reaction force, turbulence, velocity, pressure, and density. The compressive force used is 30N in each section with the load being evenly distributed and the fluid velocity used in the CFD is 4m/s.Turbin adalah mesin berputar yang mengambil energi dari aliran fluida. Turbin air adalah mesin yang mengubah energi potrensial air menjadi energi mekanik. Indonesia memiliki banyak sekali wilayah perairan seperti sungai, kali, laut, dan lain sebagainya. Sayangnya pengembangan energi baru terbarukan di Indonesia belum maksimal. Berdasarkan hal tersebut, tim merancang sebuah turbin di dalam media berupa pipa yang bernama Tulipa. Sebuah inovasi untuk memanfaatkan potensi dari energi baru terbarukan. Tulipa memanfaatkan aliran pembuangan limbah cair pada pabrik yang tidak terpakai kemudian mengubahnya kembali menjadi energi listrik. Energi yang dihasilkan Tulipa sebesar 5.593 kW. Perhitungan pada penelitian ini dibagi menjadi perhitungan kekuatan rangka batang dan simulasi. Tulipa diuji dengan menggunakan analisa mekanikal dari masing-masing komponen. Analisa dilakukan menggunakan Software Fusion 360 untuk simulasi mekanikal dan ANSYS untuk simulasi CFD atau Computational Fluid Dynamic. Simulasi dilakukan untuk mengetahui nilai static stress, reaction force, turbulency, velocity, pressure, dan density. Gaya tekan yang digunakan adalah 30N pada tiap bagian dengan beban terdistribusi secara merata dan kecepatan fluida yang digunakan pada CFD adalah 4m/s.

Abstract

Indonesia merupakan negara agraris dengan jumlah lahan pertanian sebesar 13 Juta Hektar. Iklim tropis yang dimiliki Indonesia membuat kegiatan pada dunia agriculture berjalan dengan lancar. Agriculture merupakan kegiatan untuk mendapatkan kebutuhan pokok manusia seperti beras, tumbuhan, buah, hewan ternak dan lain sebagainya. Agriculture di Indonesia menjadi salah satu penopang utama perekonomian negara. Semakin luas jumlah lahan, semakin besar pula hasil tani yang dihasilkan. Menurut Rusman Heriawan, rata-rata petani memiliki lahan sebesar 0.3 sampai dengan 0.4 hektar. Lahan pertanian yang dikekola dengan baik menjadi tulang punggung para petani dari dulu hingga sekarang ini. Petani memulai hari dengan membajak sawah dipagi hari dilanjut dengan bercocok tanam. Mulai dari penananaman pagi, pengolahan hingga menjadi beras, panen hasil perkebunan, dan lain sebagainya. Sayangnya, pertanian di Indonesia masih dilakukan secara konvensional. Oleh sebab itu diperlukan robot tani yang akan meningkatkan efisiensi para petani. Robot tani merupakan robot yang digunakan pada industri agriculture. Robot tani akan membantu petani untuk menanam padi, mengumpulkan buah buahan, dan mengelola hasil perkebunan. Robot tani dikembangkan dengan tujuan untuk memodernisasi pertanian konvensional menjadi otomatis sehingga mengurangi beban para petani serta meningkatkan efisiensi pengolahan sawah, kebun dan hewan ternak. Dengan adanya robot tani, diharapkan terjadi peningkatan otomatisasi pada industri agriculture sehingga tidak terjadi ketidakseimbangan perkembangan teknologi dengan industri yang lainnya.

Abstract

Sewer pipe water turbines are made with the aim of helping the development of new renewable energy in Indonesia. Pipe water turbines utilize unused liquid waste and convert it into electricity. In this turbine certainly has a shaft, where the shaft certainly requires bearings / bearings. Bearing is one of the components that play a role in keeping the engine shaft to keep rotating on its axis and other components on its path. An example of bearing use is in turbines. The purpose of this study is to determine the calculation of stress in bearings caused by static loads or forces exerted slowly on bearings on pipe water turbine shaft. The static load used is 30 N with AISI 304 bearing material. From the results of static stress analysis simulation obtained the maximum voltage bearing results in withstanding static loads on pipe flow water turbines.

Abstract

Beverage cans is a sheet coated of steel with tin (Sn). It is a steel sheet container coated with thin white tin that has a content value of 1.00% to 1.25% of the total weight of that can. The method used in this design is to make a truss design using special design software then determine the constituent materials and dimensions of the truss then do a strength analysis of the truss. The purpose of this design is to determine the maximum strength of the press machine truss that can be accepted with a certain force. This design starts from making a truss design with dimensions of length, width, and height are 260 mm, 100 mm, and 500 mm, respectively. The result obtained from this design are that the bending moment obtained is 43.8 MPa, the total moment of inertia is 38,286.9 mm4, the maximum stress in the truss is 23 MPa while the allowable stress according to the frame material made of Hollow iron is 124 MPa.

Abstract

The number of manufacturing industry growth in Indonesia is increasing over time. Based on the data obtained, the manufacturing industry in Indonesia recorded growth of 3.9% from July to August 2020. This study aims to analyze the effect of cutting speed on the surface roughness of S45C steel and to find out the production time for high speed cutting machining processes. This study used an experimental method, using a transverse/cylindrical turning method. Transverse turning is a lathe process when the cutting tool moves parallel or linear to the spindle axis. The test specimen will be machining starting with determining the independent parameters; feed (f) 0.2mm/rev, depth of cut (depth of cut) 0.1mm, length of cut (Lt) 100mm, then determine the dependent parameter by varying the speed of cut (Vc) starting from 125m/min to 625m/min. Based on the results of the test data obtained, it shows that (1) The higher the cutting speed, the lower the surface roughness value. This is caused by the process of plastic deformation and thixotropy phenomena. (2) The higher the cutting speed, the lower the cutting time. This is caused by the annealing phenomenon during the turning process.
