The Media

Nutrient Block is a growing medium product in the form of a square (25 x 25 cm) or cylindrical (diameter = 20 cm, height = 25 cm) made of peat which has been composted, plus adhesive gypsum or tapioca waste. Nutrient Block is designed to support the post mining land rehabilitation program that is now threatening the environmental degradation in mining areas. Nutrient Block products has been proved good for growth because of the media in addition to having physical properties that are capable of storing large amounts of water, contain enough nutrients in the form available to plants,so it can support plant growth. Results of the Nutrient Block application test to Jabon (Anthocephalus cadaba) and Sengon (Paraserianthes falcataria) plants showed that good performance, both plant height and diameter of trees and leaf growth in plants Jabon appear healthy and getting wider.keywords: nutrient block, post-mining land rehabilitation.

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.

Abstract A research project has been conducted to develop structural laminated veneer lumber products from tropical wood, and to evaluate their feasibility for the structural components of wooden houses. As part of this project, we investigated the flexural, in-plane shear, and nail shear properties of laminated veneer board (LVB) manufactured from a combination of falcataria (Paraserianthes falcataria) and rubberwood (Hevea brasiliensis) for flooring applications. In addition, 11-ply larch (Larix leptolepis) and 7-ply radiata pine (Pinus radiata) plywood were investigated as controls. Larch plywood, bonded with phenol-based adhesive, showed the best strength properties in bending and shear tests, whereas the 12-ply (28 mm thick) resorcinol-based resin-bonded LVB had the highest ductility in nail shear. The LVB also had better bending and shear properties than radiata pine plywood. In conclusion, falcataria-rubberwood LVB demonstrated good potential to substitute larch plywood and radiata pine plywood in flooring applications.

Limestone mining activities are damaging soil and enviroment. Revegetation becomes an obligation on every mining sites. Paraserianthes falcataria is one of many species that suitable to be planted in revegetation site. Adding compost and NPK fertilizer can improve soil’s condition. This research objective is to analyze the effect of compost and NPK fertilizer on Paraserianthes falcataria seedlings growth and the exact appropriate dosage for limestone mining’s soil condition improvement. The design used in this research is completely randomized design with two factors. The result shows that addtion of compost on tailing media doesn’t give major effect or statistically not significant on seedling growth of height, diameter, the amount of root nodules, and shoot-root ratio, but statistically significant on wet and dry weight of the seedlings. NPK fertilizer addition on tailing media is statistically significant on the seedling growth of diameter, wet weight, and shoot-root ratio, but not significant different on height, dry weight, and the amount of root nodules. Interaction between compost and NPK fertilizer on media gives effect only at 95% of confidence level. K1N5 sample (with 100 gram composts and 5 gram of NPK fertilizer) gives the best respond on seedling’s growth. Very high levels of Ca in the soil medium will be toxic to the Paraserianthes Falcataria plant.Keywords: Compost, limestone mining, NPK fertilizer, Paraserianthes falcataria

ABSTRACT   This research was carried out in Silviculture Laboratory, Agriculture Faculty, Sam Ratulangi University, from April to June 2012. The aim of this was to examine the influence of growth media combination on height, diameter and number of leaf sengon seedling, using a Randomized Complete Design with one factor. The factor is  top soil, top soil and sekam bakar, and top soil and coco peat. Based on the research, the results of Anaslysis of Variance showed that top soil and combination of top soil and sekam bakar give most number of seedling leaf.  However, growth of height and diameter at all of combination was no significant, but there was trend that top soil give best growth of height and best growth of diameter given by the top soil and combination of top soil and sekam bakar. Keywords : growth media, sengon ABSTRAK Penelitian ini dilaksanakan di Laboratorium Silvikultur, Fakultas Pertanian, Universitas Sam Ratulangi, pada bulan April - Juni 2012. Tujuan dari penelitian ini untuk mengetahui pengaruh kombinasi media tumbuh terhadap pertumbahan tinggi, diameter dan jumlah daun bibit sengon, dengan menggunakan Rancangan Acak Lengkap (RAL) satu faktor. Faktor tersebut adalah tanah lapisan atas, campuran tanah lapisan atas dengan pasir, campuran tanah lapisan atas dengan sekam bakar  dan campuran tanah lapisan atas dengan coco peat. Berdasarkan hasil penelitian, bahwa hasil sidik ragam menunjukkan media tumbuh tanah lapisan atas dan media tumbuh campuran tanah lapisan atas dengan sekam bakar menunjukkan pertumbuhan jumlah daun bibit sengon ang terbanyak. Sedangkan pertumbuhan tinggi dan diameter pada berbagai media yang diuji tidak berbeda nyata, tapi kecendrungan pertumbuhan tinggi tanaman terbaik ditunjukan pada media tumbuh tanah lapisan atas dan pertumbuhan diameter terbaik di tunjukkan pada media tumbuh tanah lapisan atas  dan campuran tanah lapisan atas dengan sekam bakar.

Rancangan yang digunakan dalam penelitian ini adalah rancangan acak kelompok dengan empat ulangan. Perlakuan model polatanam kelapa yang diuji sebagai berikut (1) kelapa + sengon 140 pohon/ha ♦ kacang tanah, (2) kelapa + sengon 280 pohon/ha + kacang tanah, (3) kelapa + sengon 420 pohon/ha ♦ kacang tanah, (4) kelapa + sengon 560 pohon/ha + kacang tanah, (5) kelapa + sengon 700 pohon/ha + kacang tanah dan (6) kelapa monokultur. 'Tujuan dai penelitian ini untuk mcngciahui pertumbuhan dan produksi dari beberapa model polatanam kelapa dengan tanaman sela kacang tanah dan sengon. Pengamatan dilakukan terhadap parameter agronomi meliputi data petumbuhan kacang tanah, sengon dan kelapa seta data produksi kacang tanah. Data yang diperoleh dianalisis dengan menggunakan sidik ragam dan dilanjutkan dengan uji BNJ. Hasil penelitian menunjukkan produktivitas kacang tanah pada polatanam kelapa * sengon 700 pohon/ha + kacang tanah prospektif dengan hasil mencapai 2 183 kg/ha dengan tinggi tanaman 30.25 cm dan polong isi sebanyak 9.65 buah. Sedang untuk tanaman sengon tingginya telah mencapai 312.3 cm dengan diameter 10.57 cm. Adanya tanaman sela diantara kelapa tidak menurunkan pembentukan jumlah daun, jumlah bunga betina dan jumlah tandan tanaman kelapa.</p><p>Kata kunci: Cocos nucifera, Paraserianthes falcataria, Arachis hipogea, polatanam</p><p> </p><p><strong>ABSTRACT</strong></p><p><strong>Growth and producion of peanut and albizia between coconut palms in Sukabumi, West Java</strong></p><p>The study was conducted from January to December 2001 at Caringinnunggal, Sukabumi 250 m above sea level with type of climate Bj according to Oldeman and soil type Red Yellow Podsolic.
