Abstract

Sinar matahari merupakan sumber energi terbarukan yang sangat potensial. Sebagai negara yang terletak di katulistiwa, Indonesia berpotensi menghasilkan energi matahari yang memadai, karena pancaran sinar matahari yang diterima perhari mencapai 4,5 KWH per meter persegi. Jumlah energi matahari yang dihasilkan perangkat sel surya ditentukan oleh posisi dan kemiringan panel terhadap arah datangnya matahari. Agar dapat menyerap energi matahari secara maksimal, maka diperlukan suatu alat penggerak aktif yang dapat bergerak mengikuti arah pergerakan matahari. Hal tersebut yang menjadi latar belakang penelitian ini, dimana dirancang sistem mekanik penggerak 2 axis berbasis sensor matahari berupa mini sel surya yang dapat menggerakkan panel sel surya naik turun, kenanan dan kekiri mengikuti arah intensitas tertinggi. Sistem mekanik ini nantinya akan diimplementasikan pada panel sel surya yang akan menjadi penelitian lanjutan. Dari pengukuran awal diketahui bahwa tegangan referensi pada mini sel surya sebagai penentu arah posisi panel adalah 39,17 V. Dimana sistem penggerak akan berhenti pada posisi tertentu ketika tegangan yang ditangkap mini sel surya sama dengan tegangan referensi. Konsumsi daya setiap pergerakan rotator pada masing masing axis, untuk berat beban 80 Kg adalah 84 W.

Abstract

Sunlight is a potential renewable energy source. Located at the equator, Indonesia is very potential to generate solar energy in large amounts, where the sun's rays are received per day to reach 4.5 KWH per square meter. But amount of solar energy produced by the solar cell device, is depend on panels position and its tilt follow the sunlight position. In order to absorb solar energy maximally, it would require an active driving tool, which can move the panels follow the direction of sun's movement. Its condition is the background of this research. In this research, we will design an 2 axis rotator based on a solar sensor (mini solar cells) as solar tracker, which can move the solar cell panels, up and down, right and left follow the direction of the highest intensity of sunlight. Then, this mechanical system will be implemented on an adaptive solar cell panel systems, which will be discussed on further research. From the initial measurement, it is known that the reference voltage on the mini solar cells which is used as panels direction is 39.17 V. Where the driving system will be stopped at a certain position when the voltage on mini solar cells has same value with the reference voltage. The rotator power consumption of each movement on each axis, for a 80 Kg weight load is 84 W.Keywords: 2 Axis Rotator, Solar Cell, Solar Tracker

Abstract

The stick for blindman navigational aid can only provide information about the presence of objects that being touched. This navigational aid stick can not provide more information such as object distance and the name of the place. To overcome this problem, we realized a navigational tool that can provide information about the distance of objects around the user and the name of the places where being passed. The existing objects are detected using three sets of ultra sonic sensors. These sensors emit ultrasonic signals, when the signal collide the obstacle, then will be reflected back and being received by these sensors too. The time lag between the transmitting and receiving signals then will be converted into the distance. RFID reader is used to read the presence or absence of tags around the RFID reader. Identity tag emits a signal that will be used to mark the place name. The results of measuring distance and sequence voice database recorder gives a good yield. Voice database recorder circuit works as well as the detection of RFID tags.
