LPA-AWLR Submersible Only

Tentang LPA-AWLR Submersible Only

LPA Automatic Water Level Recorder (AWLR) merupakan alat modern yang inovatif untuk mengukur kondisi tinggi muka air tanah (TMAT) gambut secara otomatis (real-time), efisien dan akurat. Alat ini dapat diperuntukan sebagai pemberi informasi peringatan dini untuk pencegahan terjadinya kebakaran pada lahan ketika tanah gambut tidak berada pada kondisi yang optimal (kekeringan).

Dasar Hukum:

PP Nomor 71 Tahun 2014 jo PP Nomor 57 Tahun 2016 tentang Perlindungan dan Pengelolaan Ekosistem Gambut
Permen LHK Nomor P15 Tahun 2017 tentang Tata Cara Pengukuran Muka Air Tanah di Titik Penaatan Ekosistem Gambut, tertera pada Pasal 6 (3) Pengukuran muka air tanah dengan cara otomatis dilakukan paling sedikit 1 (satu) data logger untuk mewakili setiap zona pengelolaan air
