RANCANG BANGUN PEMBANGKIT LISTRIK TENAGA PIKOHIDRO (PLTPH) DENGAN TURBIN ULIR (ARCHIMEDES SCREW)

ABSTRACT Screw turbine (Archemedes Screw) is a turbine that utilizes the head and water flow per second flowing in the irrigation channel. This water flow will move the turbine screw. The turbine screw movement will rotate the connecting shaft between the turbine and the generator (producing mechanical energy). The shaft will drive the generator so that the mechanical energy from the shaft will be converted into electricity in the generator. This turbine operates at low speed and is newly developed in Indonesia. But as a new turbine technology, until now there are still very few theories or references available regarding the design of screw turbines. The main components of this power generator are the turbine, speed booster (gear and pulley), Boost DC Converter and battery. In measuring water discharge, the floating method is used to calculate the available water discharge. The electric power generated will be stored in a 12v 7.5 Ah battery. The generator power of the device is designed to reach a maximum point, when the water discharge is 134 liters per second, with a voltage of 5 volts which will be increased the voltage to 12.5 volts and a current of 0.53 Ampere as the battery power supply.

ancang Bangun Pembangkit Listrik Tenaga Pikohidro (PLTPH) Dengan Turbin Screw

Pemanfaatan air sebagai irigasi tentunya juga bisa kita manfaatkan sebagai pembangkit listrik tenaga air dalam skala kecil, dengan memanfaatkan aliran air yang ada kita bisa membuat alat pembangkit listrik skala kecil yang menyesuaikan besarnya aliran air irigasi persawahan. Maka dari itu hasil dari penelitian pembuatan alat turbin ulir sebagai pembangkit listrik skala kecil guna penerapan energi di area persawahan bisa bermanfaat di masyarakat. Sebelum melakukan pembuatan turbin dilakukan survey irigasi sawah dan menganalisis debit dan kecepatan aliran air. Setelah itu dilakukan analisis berdasarkan parameter turbin yang terdiri dari sudut turbin, sudut ulir, diameter turbin, jarak antar sudu (pitch), Panjang turbin, jumlah ulir turbin dan efisiensi turbin. Alat ini memiliki prinsip yang sama dengan Pembangkit Listrik Tenaga Air (PLTA) yaitu dengan memanfaatkan air sebagai penggerak utama turbin yang kemudian turbin akan memutar generator. Daya listrik yang dihasilkan akan disimpan ke dalam baterai 12v 7,5 Ah. ketika debit air 134 liter per detik, dengan tegangan 5 volt yang akan dinaikkan tegangannya menjadi 12,5 volt dan arus sebesar 0.58 Ampere sebagai catu daya baterai. pengisian tercepat yaitu sebesar 13.89 jam didebit 134liter per detik dengan tegangan 12.53 volt
