Abstract

Peatlands is one of the ecosystem types in tropical rainforests. Peatland has very high conservation value and other functions such as the hydrological function carbon stocks, and biodiversity which is important for environmental comfort and animal life. The purpose of this study was to obtain information about the impact of fires on the physical and chemical properties of burning and non burning peat soils. This study carried out a field survey method with deliberate sampling (purposive sampling). The results showed that the physical and chemical properties of peat soil after a fire did not change, namely at soil temperature, air humidity was almost the same while the air temperature, soil moisture, pH, C-organic, depth, C/N (0-20 cm) has increased but not significantly. For the chemical properties of peat soil after fire there is an increase in the value of C-organic, CEC, phosphorus, sulfur,ash content, N-total depth (21-40 cm). this means that after fires the nutrients mostly affect peat soil. From the information on the nature of peat soil obtained in land restoration studies to use qualitative soil after burning.Keywords: Burn, chemical pea soil, Peatlands, Physicalpeat soil.

Abstract

The coast of Mempawah Regency is dominated by mangrove forest ecosystems. The mangrove forest has decreased a lot every year. The shrinkage that occurs in mangrove forest is not only caused by natural factors (abrasion and wind) but also due to logging activities by the local community. The degradation the occurs in mangrove forests is much influenced by the wives and tides of the sea. The existence of mangrove forest is thought to be very important to reduce the threat of degradation and can play a role in mitigating the damage to existing ecosystems. The function of mangrove forest in mitigating the threat of degradation encourages a further study of mangrove forest which is thought to has a physical function as a barrier to ecosystem damage. The method used is a survey method with sampling using the line transect technique. The technique of collecting data in the field uses a line transect technique that has been designed for placement. The results showed that there were three types, namely A. marina, R. apiculate, Crips decanal  tree level, the value of cover and density (tree / ha) is calculated to determine the standard criteria for determining mangrove forest damage. The closing rate is very high with a final value of 99.61%. The results of the calculation of the density value (trees / ha) above > 1500 amounting to 14,866.67, this shows that the tree density in the mangrove forest in Mendalok Village is very high. Based on the data from the analysis, Polaria Tanjung Pagar mangrove forest generally has the ability to minimize the degradation.Keywords: coverage, degradation, density, mangrove, mitigationAbstrakPesisir Kabupaten Mempawah didominasi oleh ekosistem hutan mangrove. Hutan mangrove tersebut banyak mengalami penyusutan setiap tahunnya. Penyusutan yang terjadi pada hutan mangrove selain disebabkan oleh faktor alam (abrasi dan angin) juga disebabkan adanya aktivitas penebangan oleh masyarakat sekitar. Degradasi yang terjadi di hutan mangrove banyak dipengaruhi adanya gelombang dan pasang surut air laut. Keberadaan hutan mangrove diduga sangat penting untuk mengurangi ancaman degradasi dan dapat berperan untuk memitgasi kerusakan ekosistem yang ada. Fungsi hutan mangrove dalam memitigasi dari ancaman degradasi ini mendorong untuk dilakukannya pengkajian lebih dalam terhadap hutan mangrove yang diduga memiliki fungsi fisik sebagai penahan kerusakan ekosistem. Metode yang digunakan adalah metode survey dengan pengambilan contoh mengunakan tehnik garis transek. Tehnik pengambilan data di lapangan mengunakan tehnik garis transek yang sudah didesain penempatannya. Hasil penelitian menunjukkan bahwa ditemukan tiga jenis yakni Avicennia marina, Rhizopora apiculata, Ceriops decandra. Tingkat pohon dihitung nilai penutupan dan kerapatan (pohon/ha) untuk mengetahui kriteria baku pedoman penentuan kerusakan hutan mangrove. Tingkat penutupan sangat tinggi dengan nilai akhir sebesar 99,61%. Hasil perhitungan nilai kerapatan (pohon/ha) diatas >1500 sebesar 14.866,67, hal tersebut menunjukkan kerapatan pohon di hutan mangrove Desa Mendalok sangat tinggi. Berdasarkan data hasil analisis pada hutan mangrove Polaria Tanjung Pagar secara umum memiliki kemampuan dalam meminimalisir terjadinya degradasi.Kata Kunci: Degradasi, mitigasi, mangrove, kerapatan, penutupan.
