Analisis Potensi Dan Karakteristik Gambut Sebagai Bahan Pertimbangan Untuk Arahan Perencanaan Pengembangan Kawasan Di Kabupaten Siak

Abstract

Peat land resources have the potential to be managed sustainably. Peatlands as a fragile ecosystem utilization should consider its characteristics, such as depth, maturity, fertility, land cover conditions, and calorie content. Peatland resources located in Siak Regency is a land system called Mendawai (MDW) and Gambut (GBT), whereas according to the USDA classification (2003) is land unit called Tropofibrist, Tropohemist and Troposaprist. For further management, peatland area in Siak District grouped into 7 regions peat dome : Buatan, Bukit Batu, Kandis, Merempan, Siak Kecil, Sungai Mandau and Zamrud. Based on the level of soil fertility, maturity and depth of peat, the peat areas suitable for agricultural development is the Siak Kecil, Sungai Mandau and Zamrud. Considering the condition of land cover and ecosystem components, Zamrud peat dome should be allocated to the conservation area. While based on calorie content and level of maturity, Mandau and Buatan peat dome are suitable for industrial development of peat-based materials

Pengaruh Pemberian Pupuk Zincobor dan Kombinasi Zincobor + Dolomit terhadap Kelurusan Batang dan Tinggi Tanaman Akasia di Lahan Gambut

“…Riau terdiri dari 12 Kabupaten, salah satunya adalah Kabupaten Siak. Kabupaten Siak memiliki potensi lahan gambut yang cukup luas sekitar 461.527 Ha yang digunakan sebagai lahan budidaya tanaman perkebunan dan HTI (Soewandita dan Nana 2011). Menurut penelitian yang dilakukan oleh Siahaan dan Sumadi (2016) tanaman Acacia crassicarpa (A. crassicarpa) merupakan tanaman yang cocok untuk ditanam pada lahan gambut.…”

The Impact of canal blocking to reduce fire risks and carbon emissions on tropical peatland, Siak District, Riau Province

“…In general, the types of land cover and land use of each peat area in Siak District have different types of land cover and land use. The land cover and land use conditions of peatlands in Siak District include oil palm plantations, secondary swamp forests, open land, industrial plantations, conservation areas/primary swamp forests [19]. The climate of Siak District is classified as an isothermal climate with tropical rain according to the Koppen system.…”

“…In addition, the degraded peatlands are one of the triggers for the peatland subsidence and the lowering of the water table. This has caused Indonesia's peatlands to shift from carbon sinks to carbon emitters from forest and peatland fires [11][12][13][14][15][16][17][18][19][20][21][22]. Peatland fires occur almost every year in Indonesia, causing haze disasters that affect the economy and public health.…”

Neraca Air Ekosistem Hutan Alam Gambut di Kawasan Taman Nasional (TN) Zamrud, Semenanjung Kampar Riau

“…Lahan gambut yang terbentuk secara alamiah dicirikan dengan kondisi ekosistem yang selalu basah, memiliki fungsi sebagai pengatur air dan media penyimpan air. Secara hidrologis, wilayah gambut berfungsi sebagai daerah tangkapan air, daerah simpanan air bagi daerah hilir, sistem kontrol, pengatur fluktuasi air, pencegah banjir dan pencegah terjadinya penggaraman air (saline water intrution) (Soewandita, 2011;Acreman & Holden, 2013). Material gambut yang masih alami (tidak tergannggu), 90% terdiri dari air, dan 10% sisanya merupakan sisa bahan organik yang mengalami dekomposisi (Jaenicke, Wösten, Budiman, & Siegert, 2010).…”
