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.

A capacitance sensor has been designed to investigate the correlation between wood capacitance value, Janka hardness rating and density. The sensor was developed based on parallel plates using copper as the electrodes. Capacitance values were measured using CV-circuit, 20 Vp-p, 2.5 MHz. Five wood specimens from forest plantation that is Karet (Hevea brasiliensis), Pulai (Alstonia sp.), Pinus (Pinus mercusii), Sengon (Paraserianthes falcataria), and fast growing teak (Tectona grandis) were tested. Each specimen was measured in tangential and radial directions under 0% moisture content conditions. The designed sensor was capable to distinguish the capacitance values in tangential and radial directions. The measurement results showed that wood capacitance value has a good relation with wood’s hardness and density.

The aim of this research was to study the in vitro ruminal fermentability of supplementation of <em>Gliricidia sepium, Moringa oleifera</em>, Lamk (<em>MOL</em>), <em>Ceiba pentandra</em> and <em>Paraserianthes falcataria </em>leaf meal in concentrate feed to be tested on sheep.<strong> </strong>This research with the experimental methods was arranged in Randomized Block Design (RBD) with 6 treatments and 3 groups. The treatment feed tested consisted of concentrate without leaves and concentrate with leaf meal supplementation. Crude protein content (CP) concentrates were prepared 16%, 18% and 20%. Supplementation uses a mixture of <em>Gliricidia sepium, MOL</em>, <em>Ceiba pentandra</em> and <em>Paraserianthes falcataria </em>leaf meal in concentrate feed (1: 1: 1: 1) as much as 10%, 20% and 30%. The measured variables were  degradation of dry matter (DDM) and degradation of organic matter (DOM), gas production rate, microbial biomass and NH<sub>3</sub> concentration. The use of mixed leaf meal in concentrate feed resulted in in vitro DDM as well as concentrate feed without leaf meal supplementation. Supplementation of leaf meal in concentrate feed as much as 30% with CP 20% resulted in a decrease in the value of fermentability. The supplementation of leaf meal in concentrate feed as much as 20% in concentrate feed with CP 18% produced the best fermentability value. Suggested for in-vivo trials on sheep using 18% protein concentrate feed by utilizing <em>Gliricidia sepium, MOL</em>, <em>Ceiba pentandra</em> and <em>Paraserianthes falcataria </em>leaf meal in concentrate feed as cheap protein sources.

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.

Penelitian ini dilaksanakan untuk mengevaluasi karakteristik fermentasi beberapa jenis leguminosa di dalam cairan rumen kambing secara in vitro. Desain penelitian menggunakan rancangan acak kelompok pada 7 jenis tanaman dalam 4 kelompok cairan rumen yang berbeda. Tanaman leguminosa yang digunakan antara lain, Alfalfa (Medicago sativa), Angsana (Pterocarpus indicus), Gamal (Gliricidia sepium), Indigofera (Indigofera zollingeriana), Kaliandra (Calliandra callothyrsus), Lamtoro (Leucaena leucochephala), dan turi (Sesbania grandiflora). Peubah yang diamati antara lain produksi gas total, kecernaan bahan kering, bahan organik, dan protein. Data dianalisis menggunakan analisis ragam (ANOVA). Hasil penelitian menunjukkan bahwa produksi gas tanaman indigofera dan alfalfa lebih memperlihatkan tren yang lebih tinggi dibandingkan empat tanaman lainnya. Kecernaan bahan kering (KCBK) dan bahan organik (KCBO) memperlihatkan perbedaan yang nyata (P<0,01) dimulai dari yang tertinggi adalah Indigofera, alfalfa, gamal, turi, lamtoro, kaliandra dan angsana. Terdapat interaksi yang nyata (P<0,05) antara perlakuan dan kelompok. Tanaman I zollingeriana memiliki karakteristik fermentasi rumen yang lebih baik dibandingkan tanaman leguminosa lainnya.Kata kunci: fermentasi rumen, in vitro, leguminosa
