In this study, we tested the feasibility of using UAV-acquired soil surface temperature to monitor groundwater level in a peatland undergoing groundwater restoration to mitigate fire risk (Tanjung Leban, Indonesia). We used two UAVs (Inspire 1, with an infrared camera, and Phantom 4) to map soil surface temperatures at 459 points on bare land. Using a spline analysis of groundwater-level and elevation data in Arc GIS 10.6, we produced ground elevation and groundwater table maps and measured the groundwater level (depth from the ground surface) at each bare-land point. Spearman’s rank correlation analysis determined a negative correlation between the soil surface temperature and groundwater level. Our study shows that soil surface temperature is a reliable proxy for groundwater level in tropical peatlands. This proxy can be monitored cost-effectively using UAVs equipped with infrared cameras.

The purpose of this study were to reduce organic matter and H2S. The method was used in experimental to know a combined of tank unit and filtration. Results of organic matter during the observation reaches 93.47% effectivity and H2S with 96.8% effectivity. While the other parameters such as pH 7, temperature 28 0C, and DO 5 mg / l. in the control of organic matter and H2S quality standard that is still above organic substances and to H2S with an. Examination on fish survival rate in the processed water continuous peat at the end of the observation system has been able to support fish life test. Where to carp (Cyprinus carpio) survival achieve 100%. While examination to control all test fish death until the end of the observation. Keywords : organic matter, H2S, Water Peat, goldfish habitat

Research paper thumbnail of Dinamika Penggunaan, Kebakaran, dan Upaya Restorasi Lahan Gambut: Studi Kasus di Desa Tanjung Leban, Bengkalis

Tulisan ini bertujuan menguraikan persoalan penggunaan lahan gambut, kejadian kebakaran, dan restorasi lahan gambut dari perspektif sosial ekonomi. Telah dilakukan penelitian dengan pendekatan studi kasus di Desa Tanjung Leban, Kecamatan Bandar Laksamana, Kabupaten Bengkalis, Provinsi Riau. Pengumpulan data dilakukan dengan cara wawancara terstruktur dan mendalam, FGD, dan observasi partisipatif dengan cara tinggal bersama masyarakat. Dari data yang dikumpulkan, dapat dikatakan bahwa persoalan lahan untuk pertanian adalah kompleks, terutama persoalan kepemilikan lahan oleh orang luar Desa. Masyarakat pada umumnya latah melakukan budidaya tanaman sawit, namun sayangnya lahan selalu terbakar secara berulang. Kemudian ada upaya kegiatan restorasi gambut, sebagai usaha pemulihan ...
