Pengaruh Tinggi Muka Air Tanah dalam Upaya Pengendalian Kebakaran Hutan dan Lahan Gambut

Abstract

Pengendalian tinggi muka air gambut berperan sebagai indikator terjadinya kebakaran hutan dan lahan. Penelitian ini bertujuan menganalisis hubungan tutupan lahan dengan jumlah hotspot, perubahan tinggi muka air pada tutupan lahan, hubungan curah hujan dengan jumlah hotspot, hubungan tinggi muka air gambut dengan curah hujan dan hotspot. Penelitian ini menggunakan data curah hujan, hotspot, tinggi muka air, dan tutupan lahan periode 2019-2023. Hubungan antara curah hujan, hotspot, dan tinggi muka air di analisis menggunakan uji korelasi spearman. Hasil penelitian menunjukkan bahwa kebakaran terjadi akibat konversi lahan gambut menjadi perkebunan. Hasil uji korelasi antara curah hujan dan hotspot menunjukkan korelasi lemah sebesar -0,340 dengan P-Value 0,008. Hasil uji korelasi antara tinggi muka air dan curah hujan menunjukkan korelasi sangat lemah sebesar 0,028 dangan P-Value 0,833. Hasil uji korelasi antara tinggi muka air dan hotspot menunjukkan korelasi sangat lemah sebesar -0,017 dengan P-Value 0,901.

Groundwater level control serves as an indicator of potential forest and land fire. This study aims to analyze the relationship between land cover and the number of hotspots, changes in groundwater level across in land cover, the relationship between rainfall and hotspots occurrences, and the relationship between peat groundwater level with rainfall and hotspots. The research utilized rainfall, hotspot, groundwater level, and land cover from the 2019–2023 period. The relationships among rainfall, hotspots, and peat groundwater level were analyzed using the Spearman correlation test. The results showed that fires occurred mainly due to the conversion of peatlands into plantations. The correlation test between rainfall and hotspots showed a weak negative correlation of -0,340 with a P-Value of 0,008. The correlation between groundwater level and rainfall showed a very weak negative correlation of 0.028 with a P-Value of 0,833. The correlation between groundwater level and hotspots showed a very weak positive correlation of -0,017 with a P-Value of 0,901.
