Abstract

This research aims at measuring carbon (C) stock of gmelina (Gmelina arborea Roxb.) agroforestry system and its carbon diynamics due to several harvesting rotations. Observation was conducted during March – October 2014, on 17 plots in private forest, located in Tasikmalaya and Banjar District, West Java Province. The C-stock measurement followed Rapid Carbon Stock Appraisal Method (RaCSA) with some additional analysis. The dynamic of C-stock was measured based on biological rotation, technical rotation-1 (harvesting at tree diameter of 15 cm) and technical rotation-2 (harvesting at tree diameter of 20 cm). The result of the study shows that average of C-stock in gmelina agroforest stand is 170 ton/ha, consisted of 64 ton/ha above ground C and 106 ton/ha below ground C. Biological rotation (8 years) results in maximum C-stock of 15 ton/ha  at harvesting time, while the time averaged-C stock is 7 ton/ha/year.Technical rotation-1(14 years) and technical rotation-2 (24 years) result in maximum C-stock of 23 ton/ha and 28 ton/ha respectively, while the time averaged-C-stock are 12 ton/ha/year and 18 ton/ha/year respectively.Keywords: agroforestry system, biological rotation, gmelina, technical rotation

Abstract

Pemanfaatan jenis tanaman penghasil minyak kayu putih di Taman Nasional(TN) Wasur perludidukung data dan informasi yang akurat. Hal ini menjadi penting mengingat eksploitasi yang tidak terkendali dapat menyebabkan terganggunya fungsi kawasantamannasional. Penelitian ini bertujuan untuk mengetahui sebaran spasial tigajenis tanaman penghasil kayu putih, yaitu jenis Asteromyrtus symphyocarpa, Melaleuca cajuputidan Melaleuca viridiflorayang ada di kawasan TN Wasur. Secara umum sebaran tigajenis tanaman penghasil kayu putih sebagian besar berada pada wilayah Yanggandur.Pusat sebaran ketiga jenis kayu putih ini berada di sekitar Kampung/Desa Yanggandur, Mbembi, Wasur dan Sota.Sebaran ketiga jenis penghasil minyak kayu putih ini sebagian besar terdapat di sekitar rawa, khususnya di Rawa Sermayam, Rawa Buaya dan Rawa Biru. Luas habitat ketiga jenis penghasil kayu putih adalah 103.011,75 ha. A. symphyocarpa merupakan jenis yang mendominasi Taman Nasional Wasur yaitu 8,30% dari luas taman nasional, diikuti oleh jenis M. cajuputi seluas 8,27% dan M. viridiflora seluas 7,03%. Jenis A. symphyocarpaumumnya dominan tumbuh pada jenis tanah Kambisol, sedangkan M. cajuputi dan M. viridiflora tumbuh dominan pada jenis tanah Kambisol dan Gleysol.
