Abstract

Forest and land fires can cause damage to forest ecosystems. Repeated fires cause the natural succession to be disrupted. Therefore, based on these problems, to improve the productivity of land after fires in Central Kalimantan, rehabilitation efforts needs to be done. This study aims to analyze the growth response of forestry plants in post-fire area with different soil types. This study consisted of six combinations of treatments namely controls (B0C1 and B0C2), treatment of dolomite, biochar, and compost (B1C1 and B1C2), and treatment of dolomite and NPK (B2C1 and B2C2) that planted randomized and rows Trees species were used in this research were Paraserianthes falcataria, Anthocephalus cadamba, Acacia mangium, and Campnosperma auriculata. Soil samples were also collected for analysis of soil physical and chemical properties on laboratory. This study showed that fertilization treatment significantly affected the increase of height and diameter of four trees species, while planting techniques (randomized and rows) did not significantly affected the increase of height and diameter of four trees species. Dolomite, biochar, and compost application significantly affected the increase of height and diameter of four trees species that planted randomized and rows (B1C1 and B1C2) in Podsol soil. Besides that, NPK and dolomite application significantly affected the increase of height and diameter of four trees species planted by randomized and rows (B2C1 and B2C2) in Acrisol soil. The fastest growth rate was A. mangium followed by P. falcataria, A. cadamba, and C. auriculata on Podsol and Acrisol soil. Based on the observations, P. falcataria, A. cadamba, A. mangium, and C. auriculata are recommended to be planted on both types of soil. Keywords: forestry plants, growth respon, Gunung Mas Regency, land rehabilitation, soil types

Abstract

Coal mining activities could potentially interfere with the environment. One of the environmental disturbances in coal mining activities is theformation of acid mine drainage (AMD). AMD management can be done passively through the construction of swamp forest. The constructed swampforest system uses organic material in the form of cow manure which serves as a growing plants’ medium. Phytoremediation is an attempt to usevplant species in the accumulation of heavy metals. This study was aimed to know the AMD management system passively and identify the diversity ofplants in artificial swamp forests. Purposive sampling method with a sample size of 2 x 2m in 10 plots/compartments was used to identify the plantdiversity in constructed swamp forest. The observation was made both before and after AMD flowed. Constructed swamp forest consist of 6compartments (2 sediment pond compartments and 4 swamp compartments). The results of the vegetation analysis found that before the AMD flowed,21 species are still capable growing naturally in constructed swamp forest, however, it became 15 after the AMD flowed. Cyperus iria, Fimbristylisgriffithii, Scirpus juncoides, Ludwigia hyssopifolia, Cyperus platystylis and Monochoria vaginalis are six dominant species that can be used asphytoremediation agent in constructed swamp forest.Keywords: Acid Mine Drainage, constructed swamp forest, phytoremediation

Abstract

Pemanasan global maupun deforestasi merupakan salah satu permasalahan paling serius untuk lingkungan. Rehabilitasi hutan dapat dilakukan sebagai salah satu upaya penyerapan emisi karbon. Penelitian bertujuan untuk menentukan besaran biomassa, karbon serta penyerapan CO2 sebelum dan setelah rehabilitasi dengan metode non destruktif. Penelitian dilakukan pada lima tutupan lahan (lahan rehabilitasi 2015, 2016, 2017, lahan terbuka, dan hutan sekunder) di tiga kecamatan (Manuhing, Rungan Barat, dan Manuhing Raya) di Kabupaten Gunung Mas, Kalimantan Tengah. Kandungan biomassa di atas permukaan tanah pada lahan rehabilitasi tertinggi baik pada tahun tanam 2015 maupun 2016 terdapat di Kecamatan Manuhing Raya, sedangkan pada tahun 2017 di Kecamatan Manuhing, hasil tersebut terjadi karena adanya input tambahan berupa pupuk alami di lokasi tersebut sehingga meningkatkan kesuburan tanah dan menjadikan pertumbuhan tanaman lebih baik. Total biomassa pada beberapa tutupan lahan di Kabupaten Gunung Mas semakin menurun dengan urutan: hutan sekunder (465,12-806,48 ton/ha) > lahan rehabilitasi (0,77-84,89 ton/ha) > lahan terbuka (0,001-0,06 ton/ha). Simpanan karbon mengalami penurunan yang sangat drastis dari 310,24-418,62 ton C/ha menjadi 7,25-29,43 ton C/ha karena deforestasi dan alih fungsi hutan. Kegiatan rehabilitasi mampu meningkatkan kembali kemampuan suatu lahan dalam menyerap dan menyimpan cadangan karbon secara berkelanjutan. Kata kunci: cadangan karbon, hutan sekunder, lahan rehabilitasi, lahan terbuka, rehabilitasi
