Kebakaran hutan dan lahan merupakan bencana alam yang terjadi berulang hampir setiap tahun di Indonesia, dan mengakibatkan kerugian ekonomi yang besar maupun bagi lingkungan. Penggunaan data satelit penginderaan jauh dalam menurunkan informasi fire hotspot dapat digunakan untuk melakukan pemantauan kebakaran lahan gambut (peat) dan tanah mineral (non-peat) di Indonesia. Sistem pemantauan harian sangat diperlukan untuk membantu pemangku kepentingan di lapangan dalam mengambil tindakan mitigasi bencana. Tujuan penelitian ini adalah membangun sebuah model filtering dan clustering untuk deteksi dini kebakaran hutan dan lahan di Indonesia dengan data sensor Visible Infrared Imaging Radiometer Suite (VIIRS) dari satelit Suomi NPP dan NOAA-20 menggunakan metode Euclidean distance. Model filtering dan clustering digunakan untuk menyederhanakan jumlah fire hotspot yang sangat bermanfaat bagi kepentingan di lapangan ketika terjadi kebakaran hutan dan lahan. Model filtering dilakukan dengan cara membangun peta hotspot per tahun dengan kejadian pengulangan melebihi suatu ambang batas, dan peta tersebut akan digunakan sebagai filter dari data fire hotspot yang dihasilkan. Model clustering dilakukan dengan menggunakan menghitung jarak Euclidean antar titik fire hotspot yang dihasilkan, jika jaraknya memenuhi 1,5 kali ukuran piksel maka titik fire hotspot tersebut akan dikelompokkan menjadi satu cluster. Nilai akurasi dievaluasi berdasarkan estimasi luas kebakaran, peta burned area, dan peta lahan gambut dari setiap kejadian kebakaran yang dilaporkan petugas lapangan. Hasil pengolahan dan analisis menunjukkan bahwa akurasi efektif pada data VIIRS yaitu pada jarak 1,5 km atau empat kali ukuran pikselnya dari pusat kebakaran. Akurasi deteksi secara umum untuk cluster hotspot (cluster-HS) dan titik hotspot (titik-HS) masing-masing sebesar 52% dan 53%. Untuk wilayah yang luasnya lebih dari 14 ha, akurasinya menjadi sangat baik yaitu sampai dengan sebesar 83%. Analisis dengan pemilahan lahan gambut dan tanah mineral menunjukkan cluster-HS berkinerja lebih baik di lahan gambut dengan akurasi sebesar 62% dibandingkan di lahan tanah mineral sebesar 57%. Tanpa mengurangi ketepatan pengamatan titik api, penelitian ini menunjukkan bahwa model dapat diandalkan untuk membantu pemangku kepentingan di lapangan dalam mengambil tindakan. Oleh karena itu, model ini dapat diimplementasikan ke dalam pemantauan hotspot harian di Indonesia. ......In Indonesia, forest and land fires are frequent natural catastrophes that do significant damage to the environment and economy. The use of remote sensing satellite data to derive fire hotspot information can be used to monitor peat and non-peat land fires in Indonesia. A daily monitoring system is very necessary to assist stakeholders in the field in taking disaster mitigation actions. The aim of this research is to build a filtering and clustering model for early detection of forest and land fires in Indonesia using Visible Infrared Imaging Radiometer Suite (VIIRS) sensor data from the Suomi NPP and NOAA-20 satellites using the Euclidean distance method. The filtering and clustering model is used to simplify the number of fire hotspots which is very useful for interests in the field when forest and land fires occur. The filtering model is carried out by building a persistent hotspot map per year with repeated events exceeding a threshold, and this map will be used as a filter for the resulting fire hotspot data. The clustering model is carried out by calculating the Euclidean distance between the resulting fire hotspot points. If the distance is 1.5 times the pixel size, the fire hotspot points will be grouped into one cluster. Accuracy values ​​are evaluated based on estimates of fire area, burned area maps, and peatland maps for each fire incident reported by field officers. The results of processing and analysis show that the effective accuracy of VIIRS data is at a distance of 1.5 km or four times the pixel size from the center of the fire. The general detection accuracy for hotspot clusters (cluster-HS) and hotspot points (point-HS) is 52% and 53%, respectively. For areas larger than 14 ha, the accuracy is very good, namely up to 83%. Analysis by separating peat and non-peat land shows that the HS-cluster performs better on peat land with an accuracy of 62% compared to 57% on non-peat land. Without reducing the accuracy of hotspot observations, this research shows that the model can be relied on to assist stakeholders in the field in taking action. Therefore, this model can be implemented into daily hotspot monitoring in Indonesia.

[ABSTRAK
Kebakaran lahan dan hutan merupakan ancaman terhadap lingkungan hidup. Kebakaran lahan dan hutan dipengaruhi oleh pola penggunaan lahan untuk budidaya. Karakteristik wilayah rawan kebakaran di Kabupaten Pelalawan adalah wilayah yang memiliki kawasan hutan dengan fungsi hutan produksi konversi dan hutan produksi terbatas; memiliki tutupan lahan dengan jenis hutan lahan kering sekunder, semak belukar, semak belukar rawa dan tanah terbuka; serta memiliki jenis tanah dan sistem lahan berupa endapan aluvial dan tanah mineral perbukitan rendah, serta jenis tanah gambut dengan kedalaman rendah sampai sedang. Kemunculan hotspot sebagai indikator kebakaran lahan dan hutan memiliki hubungan dengan pola curah hujan rendah yang terjadi dua kali selama setahun di Pelalawan, yaitu antara Januari─Februari dan yang paling ekstrim pada Juli─Agustus. Langkah mitigasi kebakaran yang dilakukan pemerintah belum diikuti dengan alternatif solusi budidaya tanam tanpa api. Perubahan budidaya jenis tanaman semusim ke tanaman keras adalah bentuk adaptasi yang dilakukan masyarakat. Laju pertumbuhan penduduk berpengaruh nyata terhadap peluang terjadinya kebakaran lahan dan hutan. Tekanan terhadap penguasaan ruang sebagai dampak dari pembangunan mempengaruhi kearifan lokal penggunaan api dalam pengelolaan lahan. Terbatasnya akses terhadap modal perekonomian menjadi salah satu faktor penghambat trasformasi sosial ekonomi dan budaya dari pertanian subsisten menjadi agraris, sehingga penggunaan api masih menjadi bagian dari budaya pengelolaan lahan.

Abstrak :
Kebakaran lahan gambut di Indonesia masih memiliki tingkat kerawanan yang cukup tinggi untuk terjadi. Hal ini membuat Badan Restorasi Gambut membuat teknik pencegahan dan pengendalian bahaya kebakaran. Salah satunya adalah dengan memperhatikan penataan air dalam metode rewetting yang bertujuan untuk menjaga dan mengembalikan kelembapan lahan gambut. Metode rewetting ini menjadi dasar dari penerapan teknik canal blocking yang digunakan di beberapa lahan gambut, contohnya pada Kesatuan Hidrologi Gambut Sungai Buluh Besar. Studi kasus ini dilakukan guna menganalisis dampak dari lahan gambut yang mengalami kekeringan dan pengaruh gambut yang menggunakan metode rewetting dalam penyebaran titik api. Lahan gambut yang mengalami defisit air ternyata meningkatkan laju perambatan dari pembakaran membara dan berpotensi meningkatkan sifat hidrofobik yang dimiliki gambut. Hal ini harus dicegah dengan penjagaan tinggi muka air lahan gambut yang tidak boleh berada di bawah 0.4 m dari permukaan gambut sesuai dengan keputusan Kementerian Lingkungan Hidup KLHK No.16 Tahun 2017. Berdasarkan keputusan tersebut, maka Badan Restorasi Gambut bekerjasama dengan masyarakat setempat melakukan pengambilan data terkait penyekatan di KHG Sungai Buluh Besar. Setelah peneliti melakukan pengolahan data yang diambil dari dokumen Rencana Tindakan Tahunan Restorasi Gambut 2018 dan halaman situs sipalaga.brg.co.id, maka didapatkan nilai keandalan penjagaan tinggi muka air di lahan gambut dengan penyekatan adalah sebesar 95.83%. Ini membuat nilai neraca air per tahunnya mengalami surplus dengan asumsi kelebihan volume air di musim hujan ditampung pada kolam penampung. Fluktuasi nilai neraca air yang dihasilkan per tahunnya dikaitkan dengan penemuan hotspot di sekitar lahan gambut tersebut. Dari data data yang didapatkan menunjukkan bahwa semakin banyak neraca air yang dihasilkan maka semakin sedikit jumlah hotspot yang ditemukan.

Peatland fires in Indonesia still have a high level of vulnerability to occur. This incident made the Peat Restoration Institution make a fire prevention method. One of that is to pay attention to water arrangement in the rewetting method that aims to maintain and restore peatland moisture. This rewetting method forms the basis of the application of canal blocking technique used in several peatlands, such as in the Buluh Besar Peat Hydrology Unit. This case study was conducted to analyze the impact of peatlands experiencing drought and the effect of peat using rewetting methods in spreading hotspots. Peatlands that experience a water deficit increase the propagation rate of smoldering combustion and have the potential to improve the hydrophobic nature of peat. This fact must be prevented by maintaining the peatland water level that must not be below 0.4 m from peat surface based on the decision of the Ministry of Environment (KLHK) No.16 of 2017. Based on this decision, the Peat Restoration Agency, in collaboration with the local community, collected data related to the canal blocking in KHG Sungai Buluh Besar. After the researchers conducted data processing taken from the 2018 Peatland Restoration Annual Action Plan document and sipalaga.brg.co.id, the reliability value of water level guarding in peatlands with canal blocking is 95.83%. It makes the annual water balance value surplus with the assumption that the excess volume of water in the rainy season is accommodated in the reservoir. Fluctuations in the value of the water balance produced annually are associated with the discovery of hotspots around the peatlands. From the data obtained shows that the more water balance produced, the less number of hotspots found.
