Abstract

Optimalisasi daya yang dihasilkan sel surya dapat dilakukan dengan cara selalu menjaga arus dan tegangan pada titik maksimum. Salah satu upaya untuk mencapai titik daya maksimum ini adalah dengan menggunakan metode Maximum Power Point Tracking (MPPT) berbasis logika fuzzy. MPPT logika fuzzy diterapkan sebagai sistem kendali operasi pada konverter peningkat tegangan dc (dc – dc boost converter). MPPT logika fuzzy berfungsi sebagai pengatur tegangan referensi yang mengendalikan besarnya duty cycle yang diterapkan pada sistem switching transistor boost converter. Pada penelitian ini ditampilkan pemodelan sistem transmisi daya sel surya berbasis MPPT logika fuzzy. Sebanyak 16 modul sel surya disusun menjadi susunan 8 seri dan 2 paralel. Pada susunan ini sistem sel surya dapat menghasilkan daya maksimum sebesar 3203 watt. Pada hasil simulasi yang dilakukan didapatkan bahwa MPPT logika fuzzy dapat bekerja optimal pada suhu 35oC dan irradiasi 800W/m2. Pada kondisi ini sistem sel surya dan MPPT logika fuzzy memiliki selisih tegangan 0.37%. Namun, peningkatan daya maksimum terjadi pada suhu 40 oC dan irradiasi 950 W/m2 dengan besar peningkatan daya 33.94%.   Kata kunci : MPPT logika fuzzy, sel surya, boost konverter, tegangan referensi.

Abstract

Sea level is always changing, either influenced by meteorological aspects, gravitational forces, or geological effects. Monitoring the sea level is very beneficial, especially in such a big archipelago as Indonesia. This monitoring system is designed to use accelerometer sensor to sense the sea level changes vertically to obtain the level changes over time. This device is also featured by internet connection so that the data obtained from the sensor could be process on site using Arduino microcontroller and then sent to online website for remote monitoring process. This research is using experimental method, focusing on the electronic system design. The working flow of the research is started with literature studies and problem statement, then followed by system design, continued to software design, server building, and software and hardware integration. The last step is to test the device and analyze the result. After trial using simple pulley system, it is found that this device is able to sense the vertical level changes well, with an error for the sensor itself is at most 6 cm or about 2%. But there are some connection problems occurred between the device and the internet which resulted in a delay on the process, making the online monitoring system not perform as desired.
