Pengaruh Konversi Lahan Gambut Terhadap Ketahanan Lingkungan di DAS Kampar Provinsi Riau Sumatera

Abstract

Conversion of peatlands into production land caused a decline in environmental quality. This would result in the resilience of the peatland environment to be threatened. The objective of this research was to knew the shape of peatland conversion in each peat depth which caused the decrease of environmental quality, and to knew resilience level the extent of peat land cover for vegetation biodiversity in Riau Kampar Watershed.The method used in this research was survey and transect plot. Transect plots was used to calculated the biodiversity of peatland vegetation.The results showed that the form of conversion of peatlands that occurred in Kampar Watershed of Riau Province in the form of oil palm plantation, rubber, industrial plantation forest and settlement on peat soil with shallow depth until deep depth ranged between 47cm - 883cm. Vegetation biodiversity index value of 0 - 2,83 with low to moderate category.ABSTRAKKonversi lahan gambut menjadi lahan produksi menyebabkan penurunan kualitas lingkungan. Hal demikian mengakibatkan ketahanan lingkungan lahan gambut menjadi terancam. Tujuan penelitian adalah untuk mengetahui bentuk konversi lahan gambut pada masing-masing kedalaman gambut yang menyebabkan penurunan kualitas lingkungan, dan mengetahui sejauhmana ketahanan tutupan lahan gambut biodiversitas vegetasi di DAS Kampar Provinsi Riau. Metode yang digunakan dalam penelitian adalah survey dan transek plot. Transek plot digunakan untuk menghitung biodiversitas vegetasi lahan gambut. Hasil penelitian menunjukkan bahwa bentuk konversi lahan gambut yang terjadi di DAS Kampar Provinsi Riau Sumatera berupa perkebunan kelapa sawit, karet, hutan tanaman industri, dan permukiman pada lahan gambut yang mempunyai kedalaman dangkal sampai pada kedalaman sangat dalam, berkisar antara 47cm -883cm. Nilai Indeks biodiversitas vegetasi sebesar 0 – 2,83 dengan kategori rendah sampai sedang

Sosialisasi Pengelolaan Lahan Gambut Dalam Kegiatan Usaha Tani Berkelanjutan Di SMK Negeri 1 Rundeng

“…Kondisi basah gambut mampu membuatnya menyimpan lebih banyak karbon. (Irma et al, 2018) efek dari penebangan hutan serta terbakarnya lahan gambut maka karbon yang tersimpan lepas menjadi CO2 atau yang disebut sebagai gas rumah kaca. Pembuatan drainase pada lahan gambut yang cenderung mengeringkan air dari lahan gambut sangat berdampak buruk terjadinya kebakaran.…”

Identification method of vegetation cover changes derived from mosaic Landsat-8 Data: Case Study Sumatera, Kalimantan, and Java Island

“…The dominant vegetation changes in Riau Province can be seen visually occurring in coastal and peat areas. For example, changes in the mangrove area, besides a reduction, there was also an increase in mangrove areas [8], as well as inland forest areas and peat areas [9], plantation areas [10], and others. Information on devegetation and revegetation is crucial because changes in vegetation cover will be associated with a decrease in environmental quality [11] [12], including the causes of devegetation by burning land resulting in a very disturbing haze.…”

The Corn Development Strategy in Peat Soil With No Burning and Traditional Methods

“…It is feared that exploitation of peat will cause peat to reduce from its base because of the isostation style. Peat soil managed without a clear plan and designation will cause peat to become dry and flammable (Sagiman et al 2015;Irma et al 2018). Peat soil problems can be overcome by following various strategies, namely land preparation, water management, commodity selection, and cropping patterns, which follow the 80 characteristics of peat soil (Dariah et al 2015;Safrida et al 2018).…”
