Abstract

Power facilities that use solar radiation to generate electricity are known as solar power plants. As an alternative energy source, using the sun for energy demands has a lot of promise in today's world. The energy generated or released by a light source is the sun. As is well known, the sun provides a significant portion of the world's illumination energy. In this situation, solar energy may be used in conjunction with other machinery that contributes and has the ability to convert solar radiation into electrical energy through the use of solar panels, which are apparatuses that transform solar radiation into electrical energy. Apart from that, solar panels are the most promising and have the most potential when compared to other energy sources. It can be argued that solar panels are the primary factor in optimising the potential of solar energy reaching the earth. The weather affects solar panel performance. Solar panels must constantly be pointed in the direction of the sun's rays in order to work well, as the sun's location on the surface of the planet varies with time. From the explanation above, a plan was made for a solar power plant in Pinggir Laut Village, Rokan Hilir Regency complex using 60 units of 200 WP panels, 56 units of 12V 100 Ah batteries, 2 units of 8000W inverter, and 2 units of a charger controller with a voltage rating of 120 Ampere.

Abstract

Dewasa ini mesin listrik yang sering digunakan pada dunia industri adalah motorinduksi, hal ini karena motor induksi memiliki beberapa keunggulan dibandingkan jenis motor lain, diantaranya memiliki efisiensi yang relatif tinggi, konstrusi yang sederhana dan kuat, serta mudah dan murah dalam perawatannya. Salah satu kelemahan dari motor induksi adalah mengatur kecepatan putaran motor. Kecepatan putaran motor induksi dapat diubah dengan cara mengubah frekuensi dengan menggunakan inverter. Penelitianini bertujuan mengetahui pengaruh perubahan frekuensi terhadap kecepatan putaran motor induksi 3 phasa menggunakan inverter. Hasil penelitian ini adalah perubahan frekuensi pada inverter dapat menyebabkan perubahan kecepatan putaran motor induksi 3 phasa. Perubahan frekuensi inverter dengan cara mengatur tegangan input inverter dengan mengubah-ubah tahanan (potensio meter ) pada inverter dapat merubah kecepatan motor induksi 3 phasa.Kunci : Motor Induksi 3 Phasa, Inverter (VFD), Frekuensi, Tegangan, Putaran.

Abstract

Hydrokinetic water turbines do not require high water pressure (head) to work.Another advantage of the Darrieus turbine is that it is less sensitive to turbulencebut sensitive to flow direction. Among some forms of turbine turbine turbinegeometry, straight-angled geometry (or H-Darrieus) is more popular due to easierfabrication and simpler construction. The number of blades using the NACA type0012 H-rotor has the best self-starting effect but not for all azimuth blade positions.If the blade is fixed and unregulated then the angle of charge will change at anytime depending on the position of the blade which consequently alters thedynamic force of the water to the blade and therefore tends to occur in the lowtorque of the tubin and decrease the turbine effiency. One disadvantage of theDarrieus turbine is its low self-starting torque. So the problem in this research ishow the turbine produced performance with variation of the number of blades.The study was conducted to analyze the perforamance of low-speed darrieusturbines shown by self-starting characteristics, dynamic torque, power, andefficiency produced by turbines. The test rig comprises two main components: amodel of stream flow made of acrylic and a model of the Darrieus turbine. Rivermodels from upstream shelters, canals and downstream water reservoirs. Waterfrom upstream flows into the runner through the incoming side. Then waterflowed into the downstream storage basin. In the construction of this model is notmunggunakan draft tube. The runner house has a fully enclosed top casing with nodraft tube and wall, the water flow rate and Head of water level are set by the feedwater pump. The difference between the water level in the upstream reservoir andthe water level in the canal is kept constant. Once the above is achieved then it canbe tested. The shaft rotation is measured by the rotation sensor and the shafttorque force is measured using a load cell. Experiments carried out with variationsof torque loads with constant flow rate of water The manufacture of the Darrieousturbine model testing apparatus has been completed. This model comes with aData acquisition Tool using arduino UNO with DAQ PLX that works according toplan. In taking the research dataKey word: Darrieus turbine, hydrofoil,manufacture

Abstract

Salah satu usaha pengolahan hasil perikanan berupa pembuatan terasi. Terasi(shrimp paste) merupakan salah satu produk awetan ikan-ikan kecil atau rebonyang telah diolah melalui proses pemeraman atau fermentasi, penggilingan ataupenumbukan dan penjemuran. Persoalan terasi lainnya adalah tempat untukpenjemuran dan tingkat kekeringan terasi. Dalam penelitian dirancanglah alatpengering terasi otomatis yang diharapkan dapat meningkatkan hasil produksiterasi oleh masyarakat. Hasil dari penelitianini diperoleh hasil prototype alatpengering terasi otomatis yang tepat guna sehingga dapat mengurangipenggunaan tenaga manusia dan dapat terlaksana walau cuaca tidakmemungkinkan.Kata kunci : Terasi, Pengeringan), Ardiuno Uno.
