Abstract

Waterwheel is a means to convert water energy into mechanical energy in the form of torque at the wheel shaft. The waterwheel works with a large flow and utilizes a high waterfall. Currently waterwheels still have a small efficiency when compared to the existing water turbines. Therefore, further research is still needed to increase the rotation (rpm), mechanical power and efficiency of the waterwheel. The purpose of this study was to determine the performance of the nozzle angle variation with the natural flow of the waterwheel. In this study, using a breastshot type waterwheel with 12 blades with a water flow of 12 liters / second. By using the analysis, the results show that the mechanical data and the efficiency of the wheel are affected by the flow of water hitting the blade using a nozzle. The tilt angle of the nozzle is very important, the steeper the nozzle, the faster the water flow will hit the wheel blade. In the rotation test (rpm), the highest mechanical power and efficiency at the use of a nozzle with an angle of (25°) is at 76 rpm, which is 29 Watts and the lowest power is at 19 rpm, which is 13 Watts at a discharge of 12 liter / second. Whereas the natural flow is at the rotation 76 rpm which is equal to 7.11. Watt and the lowest power at the rotation 19 rpm namely 4 Watt at a discharge of 12 liter / second.

Abstract

The rapid development of information technology has had an impact on various fields of life and professions. An organization usually has various kinds of business processes that it wants to achieve. Business models can assist in evaluating current and common business models out of business process automation (BPA). PT. XXX is a manufacturing company that produces paper with the largest output in Indonesia. The company is committed to implementing sustainable business principles in all of its operational activities. So far, Control Monitoring activities at the company are still carried out manually, starting from taking samples, checking the standard of a spare part, to preparing reports. This causes the ineffectiveness of the work cycle, so to overcome these problems a computerized system is created in the form of a Monitoring Control System (MOS) application for the Finance & Accounting department. With this application program, it is hoped that it will be able to reduce the use of paper in the process of monitoring, recording, and speed up the preparation of reports so that they are more quickly received by other departments at PT XXX.

Abstract

A micro-hydropower plant is a small-scale power plant that uses water as its propulsion and the prime mover is a turbine. This generating system is very appropriate to be used in rural areas because this system is easy to manufacture, produces a large amount of electrical power, and is relatively inexpensive to manufacture. Based on the above, it is necessary to design a turbine that supports this generating system, including the Cross-Flow Turbine. To design a water turbine so that there are no errors in the design (such as the cost of making it), then a design is carried out. A cross-flow turbine design is designed with a flow rate (Q) = 1.2 m3/s, head (H) = 17 m with an efficiency of 0.75. The main technical specifications from the results of the turbine design are runner diameter (D) = 510 mm, turbine shaft rotation 471 rpm with a specific speed of 61.33 rpm, water power of 200,124 kW, and producing electric power of 100.86kW.

Abstract

The energy crisis is a severe problem facing the world, including Indonesia. Along with the times, innovation is needed to implement sustainable energy. Non-fossil energy sources have not been widely used, and efforts are still needed to utilize these energy sources. The waterwheel was the first device used in water production. One of the innovations for the sustainability of non-fossil energy is to make a waterwheel. There are still several waterwheels in Indonesia, but an investigation is needed to determine their condition. So in this study, investigating the breastshot water wheel uses a nozzle-based construction with variations in the degree of inclination of the spray against the TSR value. The results showed that the greater the inclination of the nozzle angle, the higher the velocity of the water flow when it enters the wheel. Adding water speed to this wheel will increase the momentum and tangential force. An increase in the tangential force will increase the wheel's torque so that the wheel strength will increase. This increase in power will, of course, result in greater efficiency, thereby increasing the tip speed ratio (TSR).

Abstract

Availability of water is a major problem in several regions in Indonesia. There are several areas, especially in Gondosuli Village, Probolinggo, which can only maximize water use during the rainy season. In addition, water has an important role for the people, most of whom work as farmers. Water is one of the main factors affecting the amount of production of agricultural land and fisheries. This problem requires the availability of sustainable water, so that it can meet daily production needs. Therefore it is necessary to use a hydram pump that can work with the help of solar power without using electricity. The working principle of the hydram pump is to convert the kinetic energy of the water flow into dynamic pressure, and as a result a water hammer is created to create high pressure in the air pipe. With the design and construction of the Hydraulic Ram Pump System, it is hoped that it can address the availability of water in a sustainable manner, so that production in agriculture and fisheries can be stable and even increase.

Abstract

PT. XXX merupakan salah satu perusahaan manufaktur yang memproduksi kertas dan hasil-hasil produksi kertas terbesar di indonesia yang terintegrasi secara vertikal. Dalam penelitian ini, akar permasalahan terhadap rendahnya produktifitas penurunan tekanan pada bagian press cylinder wire machine akan diidentifikas, FMEA akan dipakai untuk menentukan tingkat permasalahan yang menghambat produktifitas press cylinder wire machine. Metode penelitian yang dilaksanakan, menggunakan metode eksperimen. Langkah awal untuk melakukan perancangan RCM adalah mengetahui mesin yang sering mengalami kegagalan yang didapatkan dengan wawancara pihak perusahaan. Mesin tersebut adalah mesin press part, mesin size press, mesin driyer merupakan mesin yang tercatat sebagai mesin yang sering bermasalah. Mesin beserta komponennya tersebut akan dilakukan perencanaan pemeliharan menggunakan reliability centered maintenance (RCM). Identifikasi setiap kesalahan dan akar penyebab setiap kesalahan keluar dari setiap bagian mesin. Setelah analisis yang cermat dari semua bagian rakitan piston, ditentukan bahwa sebagian besar kegagalan yang ditemui disebabkan oleh penyebab yang tidak disengaja dan tegangan berlebih, kecuali semua seal dan ring piston. Berdasarkan pemilihan material, desain ulang pelat dorong dudukan jari diusulkan karena perluasan baut jari dorong yang berlebihan disebabkan oleh kelonggaran dan ketidaksejajaran.

Kecepatan angin rata-rata yang diperoleh sekitar 10 m/s. Bilah sudu yang digunakan yaitu kategori thick-airfoil family for small blades dengan tipe NREL S822 dan NREL S823. Berat turbin yang didapatkan dari hasil perhitungan sebesar 12,759 kgm/s2. Turbin ini terdapat generatorarus bolak-balik, yang dapat mengubah energi potensial angin menjadi energi mekanik untuk menghasilkan energi listrik searah (DC), digerakkan oleh poros dan katrol turbin angin, yang merupakan penerus putaran angin yang mengalir. Kepadatan bahan yang digunakan memiliki dampak yang signifikan pada bagaimana turbin angin berputar. Karena kekuatan dan ketahanan cuacanya, bahan kincir angin resin lebih efisien daripada bahan lainnya.
