~ PJU Tenaga Surya Di Balaikota

Yogya Jajaki Tenaga Surya

 

Yogyakarta, Kompas - Pemerintah Kota Yogyakarta menguji pemasangan titik penerangan jalan umum tenaga surya untuk menghemat biaya listrik dan perawatan miliaran rupiah per tahun. Uji coba dilakukan dengan pemasangan satu unit PJU tenaga surya di Balaikota, Selasa (12/1).

Kepala Seksi PJU Dinas Permukiman dan Prasarana Wilayah Kota Yogyakarta Suko Darmanto mengatakan, saat ini terdapat 19.500 PJU. Biaya yang ditanggung Rp 600 juta-Rp 650 juta per bulan dan perawatan Rp 2 miliar per tahun.

"Itu pengeluaran besar dan mestinya bisa ditekan. PJU tenaga surya kami lihat sebagai pilihan menarik karena hemat energi dan perawatannya mudah," ujarnya.

Pelopor

Wali Kota Yogyakarta Herry Zudianto akan menjajaki pemasangan PJU tenaga surya meskipun tidak di semua ruas jalan. Ia berharap, Yogyakarta menjadi pelopor penerapan energi terbarukan lewat ini.

"Hanya saja investasi awal untuk teknologi seperti ini memang mahal. Tapi, lama-lama saya rasa tetap bisa terjangkau jika digunakan secara massal. Seperti telepon seluler, dulu barang mahal, tapi sekarang tak lagi dianggap begitu," ujar Herry.

Satu unit PJU tenaga surya di Balaikota seharga Rp 30 juta-Rp 35 juta. PJU memakai baterei dan aki sebagai sumber pembangkit tenaga untuk menyalakan lampu LED (light emiting dioda) berkekuatan 50 watt. Kekuatan LED tak kalah dengan lampu 200 watt.

Direktur Sky Energy Jekson Tandiono mengatakan, PJU ini agak berbeda dengan PJU tenaga surya lain karena menyerap gelombang dalam radiasi sinar matahari. Walaupun mendung, radiasi matahari tetap ada dan bisa diserap alat tersebut. (PRA)
