Abstract

The lack of energy commodities such as coal and petroleum makes the cost of these commodities soar. This event shows how much countries in the world are still very dependent on fossil fuels, and it is fitting that the transition to new renewable energy can be realized soon, low emission and environmentally friendly energy is the hope in the future. Indonesia has a supply of renewable energy sources that are abundant is a great force for this clean energy revolution. The momentum of the presence of the first wind farm in Indonesia operating in Mattirotasi Village, Sidrap Regency, Central Sulawesi in Indonesia with a wind power plant capacity (PLTB) of 75 MW is positive evidence that the government is starting to pay more attention to the development of renewable energy technology in Indonesia. Turbine technology that is able to optimize wind speed in Indonesia must be the answer so that this energy is more useful.  In this study, the idea for an experimental analysis of "Study of the Effect of Blade Shape Change and Lift Angle on Horizontal Wind Tubin using Nvis 6009 Experimentation with Solar and Wind Energy props. The Nvis 6009 is a prop used by vocational schools to understand the concept of a DC power plant based on solar and wind energy. To optimize low wind speed, on Nvis 6009 horizontal axis wind turbine (HAWT) with different type 3 Blade and changes in lift angle, so that we can know the effect of the resulting voltage change, so that we can know the effect of the resulting voltage change. Simple illustrations using the Solidworks application are done as validation of the results of previous research and to obtain preliminary data of research experiments. The final results of the test on Type Blade II obtained maximum data at a Blade angle of 13 ° with a wind speed of 3.9 m / s, Blade Rotation 2587 Rpm produces a voltage of 2.8 V.

Abstract

Wind Technology has developed rapidly because it is environmentally friendly alternative energy. The speed of the wind to run the wind turbine is able to exhaust a fan and ordinary wind sources. Tanjung Enim is one of Indonesia's areas, that have comparatively little wind energy. It has a wind velocity of 1.5 - 3 m/s. Tanjung Enim has coal mining, and the blower is used for air in the conveyor line of the mining. It is the potential to generate wind turbines. because the wind velocity in this area is 8 m /s. This study examines the enactment of blades on vertical wind turbines, namely Savonius with 3 blades combine with Darrius 3 blades. The result of the voltage output currently created by of vertical wind turbine maximum is 8.42 Volt and 345 Ampere.

Abstract

This study aims to provide a clear picture of the efficiency of using solar panels as an alternative energy source compared to conventional energy, as well as to keep the temperature of the solar panels stable. Where the solar panel itself has a maximum body and temperature that affects the results of the solar panel. Solar panels experience a decrease in their ability to generate electricity when they overheat or exceed their effectiveness limits. Therefore, seeing the effectiveness of solar panels working at a temperature of 25 degrees Celsius, there is a desire to take advantage of the excess heat generated from solar panels by cooling the solar panels by flowing water through a capillary tube. Where the experimental results can be seen in the graph of solar panels that have not used cooling. showed a decrease in the absorption of solar panels, precisely at 11.30 am and had a voltage of 20.2V with a temperature of 3.1℃. shows a decrease in the power produced on the day of the study where at 11.30 am there was a decrease in power to the voltage from 20.4V to 19.00 V and it can be said that this was caused by an increase in temperature in three days which was also influenced by the heat earlier.

Abstract

In organizing the Asian game event in Palembang in 2018, PT PLN Persero supported this activity by supplying electricity at several points in the Jakabaring Spot City (JSC) area with a total of 27 connecting substations with a loop system, but when the event was over the loop system was turned off and several locations of connecting substations. not deactivated due to operational constraints and the absence of activities at the location resulting in the supply to the substation shutting down but still operating distributing a voltage of 20 to several substations that are still operating in the JSC area, Indonesia has a very large renewable energy potential, especially solar energy which can supply a heater to maintain humidity prevent partial discharge and make cubicle equipment have a long lifetime. The results show that the radiation received by the PV system is sufficient to produce Stable electric power to turn on the heater continuously for 24 hours Future research will be extended to monitoring via IoT.

Abstract

The use of fossil energy is currently starting to be slightly reduced by the government, and at this time the government is also starting to look at renewable energy as alternative energy, just as energy, solar, wind, biomass, and water. One of the utilization of water energy for the use of electrical energy is with a waterwheel. In this study, a pontoon-type water wheel was designed, where the ratio of rotation of the wheel to the rotation of the generator rotor was 1: 4. The dimensions of the water wheel designed and made were with a pontoon width of 1080 mm x 2000 mm x 15 mm, and the diameter of the water wheel is 1200 mm, which can be generated by a generator of 1 watt.

Abstract

Jakabaring PLTS on-grid with a capacity of 2 MW operates from 6:00 am to 5:00 pm. At 5:00 pm the PLTS connection to the load will be disconnected and replaced with PLN. If the PLN is off due to damage or during maintenance, a generator that is operated manually will be used. Problems in the process of combining energy sources from Solar Panels to PLN require a power target of up to 10 Kva where if the power is fulfilled then the energy source from Photovoltaic (PV) will be connected to PLN and vice versa. Errors and speed in operation can be minimized by means of automation of the system operating the power supply to the load by using a PLC (Programmable Logic Controller). Optimization as a step to optimize the electricity supply in the PLTS area makes it the first source of power generation that is connected to the load, the second order is PLN if the PLTS has no power output or there is a problem and the third order is generators if PLN and PLTS have no power output. For this reason, a tool is needed that functions to move the power source alternately using a PLC (Programmable Logic Controller) as an ATS (Automatic Transfer Switch) process controller, where the tool will work automatically changing the power source if there is a disturbance that causes it to be unable to supply electricity to the user's load and also as a priority regulator of solar power sources as the main source of electricity to the load. When transferring loads from one source to another with 3 different power sources, it is faster and more effective to use an ATS (Automatic Transfer Switch) with a PLC controller compared to Manual or COS (Change Over Switch).

Abstract

Salah satu treatment untuk spasticity efek pasca stroke, fracture karena kecelakaan, injury karena cedera olahraga, dan musculoskeletal disorders karena pekerjaan kantoran pada pergelangan tangan selain dengan operasi yaitu dengan penggunaan wrist hand orthosis. Umumnya pembuatan medical device tersebut menggunakan metode konvensional yang mempunyai kekurangan. Hadirnya teknologi reverse engineering (RE) dapat diaplikasikan dalam bidang medis seperti pembuatan alat prosthetic atau orthosis. Pada penelitian ini bertujuan untuk mengembangkan desain wrist hand orthosis berbasis reverse engineering dan menganalisisnya menggunakan metode elemen hingga. Metode penelitian meliputi 3D scanning, CAD modelling, model analysis, dan post processing. Material model yang digunakan adalah ABS dengan variasi ketebalan 5 mm, 6 mm, dan 7 mm, serta besar nilai pembebanan mulai dari 5 N sampai 25 N. Hasil analisis equivalent stress menunjukkan model ketebalan 5 mm mampu menahan load 25 N dengan maximum equivalent stress sebesar 13.52 MPa yang masih tergolong aman dengan nilai safety factor 2.11 dengan area kritis di ujung punggung telapak tangan model antara ibu jari dan jari telunjuk. Hasil equivalent elastic strain dan deformation juga mempunyai tren grafik yang sama dengan nilai maximum pada model ketebalan 5 mm yaitu masing-masing sebesar 0.0057 mm dan 0.616 mm. Dari hasil analisis tersebut dapat disimpulkan bahwa model wrist hand orthosis berlubang voronoi yang memiliki bentuk seperti surface tangan manusia dengan ketebalan minimalis 5 mm mampu bekerja dengan baik memfiksasi tangan pasien untuk proses rehabilitasi.
