Electrical Energy is a very important need, but the electrical energy we use today still comes from conventional power plants that have negative threats such as pollution and fossil fuel reserves that are decreasing. To overcome this, by utilizing alternative energy that is environmentally friendly, one of them is wind energy and solar energy. Hybrid power plants use savonius helix wind turbines and solar cells are made to minimize the use of conventional energy. This tool utilizes wind and solar energy as the main media of electricity generation. The wind turbine which is made is a type of helix savonius vertical turbine that has a large torque, can rotate with low wind speed with a turbine size 80 cm high, diameter 25 cm which is connected to the generator and mounted on mechanical construction with a height of 200 cm and mounted control panel and solar cell with a capacity of 20 WP. This study aims to develop the potential of alternative energy as a power generation medium and be used as a source of flashing lights in the Indorama Engineering Polytechnic lightning tower tower. Savonius helix wind turbines that are designed require a minimum wind speed of 2.45 m / s for the start of the turbine rotation. Generating from the generator produces a maximum voltage of 18.64 V with a generator rotation of 304 rpm when not loaded and when loaded produces a maximum spin voltage of 281.3 rpm, 11.73 V voltage and 0.038 W power with a wind speed of 5 m/s. From the results of testing this hybrid power plant can be used for flashing lights on the lightning rod tower of the Indorama Polytechnic Engineering campus with a duration of 12 hours per day.
Speed bump atau dalam bahasa Indonesia disebut “Polisi Tidur”, dianggap kurang bermanfaat dan mengganggu bagi para pengendara motor untuk mengurangi kecepatan motornya. Muncul sebuah gagasan untuk merancang sebuah alat yang pada penerapannya dapat memanfaatkan sebagai pembangkit listrik dengan sumber penggerak generator dari polisi tidur. Dengan menggunakan rangkaian elektronika daya sebagai regulator dari keluaran yang dihasilkan. Metode penelitian dari alat ini adalah ketika kendaraan melewati speed bump maka akan menginjak bump yang dapat bergerak naik dan turun, kemudian gerakan dari naik dan turunnya bump tersebut diubah menjadi gerakan memutar generator. Tegangan yang dihasilkan dari generator tersebut disimpan pada accumulator yang nantinya energi listrik dapat difungsikan sesuai kebutuhan. Adapun yang menjadi tujuan dari penelitian ini adalah dapat menjadi sumber energi alternatif terbarukan sebagai penghasil listrik, dapat memanfaatkan energi yang terbuang menjadi energi yang potensial.
Indonesia is actively developing the potential for renewable energy as a substitute for depleting fossil energy reserves. Wind energy is clean energy without polluting the environment. Wind energy in Indonesia has great potential, but it is still not optimal enough for its utilization. One form of alternative energy that can be utilized as mechanical energy by wind turbines to convert into electrical energy by dc generators. Ventilators that operate for 24 hours function to suck air and, located on the roof of a warehouse, sports hall .. Utilization of wind to become electrical energy, is designed from the use of a ventilator turbine as a medium to convert wind into motion energy, where the movement of the turbine is continued by pulley and v-belt comparisons to the generator, this generator produces electricity. This research examines how much electrical energy is produced at different wind speeds ranging from 3 to 5.4 m/s. From the tests conducted, the generator rotation, and the lowest voltage is at wind speed of 3 m/s which is 3.6 V. while the generator speed and the highest voltage is obtained if the wind speed is 5.4 m/s which is 10.3 V.

Perkembangan industri hiburan seperti film saat ini sangat begitu pesat dan bervariasi, hal tersebut seringkali membingungkan para penikmat film dalam menentukan film yang sangat direkomendasikan, solusi atas permasalahan tersebut adalah suatu sistem rekomendasi film yang dapat memberikan rekomendasi film-film yang berkualitas untuk ditonton oleh penikmat film berdasarkan rating film tersebut. Twitter jejaring sosial favorit yang masih sering digunakan oleh masyarakat saat ini untuk menuliskan pikiran, perasaan maupun aspirasi dari setiap user, pada sistem ini cuitan twitter berfungsi sebagai data input yang dapat diolah menjadi suatu data yang lebih bernilai seperti rating. Penelitian ini dibahas sistem rekomendasi film berdasarkan rating dari komentar - komentar twitter menggunakan ibm bluemix dengan algoritma Support Vector Machine. Hasil Pengujian memberikan keluaran berupa rating, dimana nilai yang dihasilkan cenderung mendekati nilai rating dari situs rating film yang sudah popular dan terpercaya.
