Soil Origin

The objective of the present study was to examine the growth responses of Acacia mangium (mangium) and Paraserianthes falcataria (sengon) seedlings growing on different soil origin under nursery condition. This study was started in September 2012 and terminated in March 2013.  The seedlings were grown from seeds sown in a plastic box filled with sterilized sands. One week after sowing, the seedlings were transplanted into polybags contained sterilized soils originated from secondary forest, Imperata cylindrica grassland and ex-coal mining. The number of all seedlings were 180 seedlings consisted of 3 different soils, 2 species of seedlings with 10 seedlings replicated 3 times. Assessment was conducted one week after transplanting, then subsequently monitored every 2 weeks, except dry weighing and counting nodules were performed at the end of the study. A completely randomized design was used in this study. The data was analyzed using Costat software. The study resulted that the different of soil origin influenced on all growth variables of mangium and sengon of 4.5 months old. The survival rate of seedlings, height and diameter increments, dry weight and root nodules were better in both species of seedlings growing on soil originated from secondary forest and Imperata grassland compared with the soil from ex-coal mining. But the survival rates of sengon seedlings were higher than that of mangium on these three soils. The highest dry weight of sengon seedlings was achieved on soil originated from secondary forest. In the present study, soil originated from secondary forest increased more in weight of shoot than root, so that the shoot-root ratio was unbalanced more than one. Based on the results of this study, it is recommended that soil from secondary forest and Imperata grassland can be used as growing media for mangium and sengon seedlings in the nursery.

Revegetation is an important part of reclamation activities of mined land, partly due to potential CO2 absorption from theatmosphere, particularly through photosynthetic reactions. This research was aimed to calculate the amount of C absorbedby two major fast growing legume species in most reclaimed mined lands in Indonesia, mangium (Acacia mangium) andalbizia (Paraserianthes falcataria) at four years of age. Three tree samples of each species were destructively taken fromthe reclaimed mined land belong to PT Bukit Asam (PERSERO) Tbk, Tanjung Enim, South Sumatra to obtain plant biomassproduction of both above and below ground. The above ground plant biomass was separated into leaf, branches & twigs,and stem. All these components and the below ground biomass (roots) were then weighed for fresh weight determination.About 200 g of these tree components were dried in an oven at 70oC to obtain their dry weights, and then ground into 60mesh diameter for C analysis using wet destruction method of Walkley and Black. The results showed that up to the fourthyear, mangium sequestered C almost double of that sequestered by sengon stands, 21.66 and 10.35 kg C/tree respectively.

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

Salah satu dampak negatif dari aktifitas penambangan adalah terjadinya degradasi lahan. Degradasi lahan ditandai dengan menurunnya kondisi fisik, kimia dan biologi. Mitigasi atau upaya pencegahan harus dilakukan agar tidak berlanjut ke kondisi yang lebih parah. Revegetasi adalah langkah yang dapat dilakukan untuk mitigasi lahan terdegradasi tersebut. Keberhasilan revegetasi tergantung pada pemilihan vegetasi yang adaptif dan cepat tumbuh sesuai dengan karakteristik tanah, iklim dan kegiatan pasca  penambangan. Selain itu perbaikan kondisi fisik, kimia dan biologi lahan juga ikut menentukan keberhasilan revegetasi. Beberapa jenis tanaman cepat tumbuh (Fast Growing Plant) yang umum digunakan untuk revegetasi adalah sengon laut (Paraserianthes falcataria), akasia (Acasia mangium, Acasia crassicarpa), Lamtoro (Leucaena glauca), turi (Sesbania grandiflora), gamal (Gliricidia sepium). Selain tanaman cepat tumbuh, tanaman lokal juga menjadi pilihan untuk revegetasi. Keberhasilan revegetasi akan meningkatkan kadar bahan organik dan memperbaiki siklus hara serta meningkatkan jumlah dan aktifitas mikroba. Hal ini akan memperbaiki kondisi fisik, kimia dan biologi sehingga degradasi lahan pasca penambangan tidak terjadi lebih buruk.
