Abstract

Tulisan ini mengemukakan analisis komponen kimia kayu dari lrian Jaya sebanyak 9 jenis. Penelitian ini merupakan bagian dari penelitian sifat dasar yang dilaksanakan setiap tahun di Pusat Penelitiaan dan Pengembangan Hasil Hutan dan Sosial Ekonomi Kehutanan. Maksudnya adalah untuk mengetahui sifat kayu yang penting seperti sifat .fisis, mekanis dan kimia yang berguna bagi penggunaan kayu. Analisa yang dilakukan meliputi penetapan kadar holoselulosa, selulosa, lignin, pentosan, BJ, air, abu, silika, kelarutan dalam air dingin, air panas, alkohol benzena 1 : 2 dan kelarutan dalam NaOH 1 %. Analisa ini berguna untuk menentukan perkiraan kegunaan kayu seperti untuk pulp dan turunan selulosa.Hasil analisa memperlihatkan bahwa kadar holoselolusa berkisar antara 69,61 - 75,21 %, selulosa 47,33 - 54,80 %, lignin 24,79 - 30,39 %, pentosan 1,18 - 18,48 %, berat jenis 0,36- 0,85 g/cm3 , kadar air 9,20 - 15,44 %, abu 0,79 - 1,90 %, silika 0,33 - 1,07 %, kelarutan dalam air dingin 4,33 - 7,41 %, air panas 4,67- 9,47 %, alkohol benzena (1: 2) antara 1,99 - 9,21 % dan kelarutaan dalam NaOH 1 % antara 18,16 - 30,07 %.Berdasarkan standar FAO untuk pulp, maka 9 jenis kayu dari irian Jaya cukup baik untuk dibuat pulp.

Abstract

Dry-distillation trials of five wood species from East Kalimantan were conducted at the forest products laboratories. Bogor. and the characteristics of the products (i.e. charcoal, tar and distillate fractions) were assessed to explore their possible uses as a fuel (the source of energy), activated charcoal. carbon-based fibers, metallurgy (smelter), disinfectant, and fertilizer. The distillation was performed in an electrically heated retort. The wood species were consecutively Kayu Arang (Diospyros macrophylla), Nyaling (Mastixia trichotama). Penjalin (Drypetes). Lansat Hutan (Lansium) dan Kayu Gading (Koilodepes sp.). Before conducting the experiment, these wood species were each examined for their specific gravity and calorific values. These species showed variation in their specific gravity (0.51 - 0.93) and calorific values (4465 - 4606 cal/g). Further, the products of distillation revealed some variation in their yielas, i.e. 27.55 - 33. 75 % (for charcoal), 6.53 - 12.89 % (tar). and 47.44 - 71.92 % (pyrolignous liquor). As the charcoal, its moisture content ranged from 0.89 - 1.73 %, ash content from 3.04 - 3.40 %. volatile matter from 19.15 - 20.65 %, fixed carbon from 76.05 - 77.81 %. and charcoal calorific value from 6802 - 7086 cal/g Based on the calorific value. volatile matter, and ash content of their resulting charcoal, the five species tested were all suitable as raw materials for the manufacture of metallurgy charcoal and activated charcoal.

Abstract

One of the alternatives that can be used to develop and have significant prospect to improve the critical or degraded land is through the use or application of charcoal. Charcoal can be used as one ingredient in the media to enhance the growth of plants. particularly still at seedling stage and at the field preparation as well. The application of charcoal sould when they are increase soil pH and improve water and air circulation in the soil, there by stimulating the growth of root and the plants.This report deals with research results of applying two kinds of wood-bark charcoal, i.e. bark charcoal from tusam (Pinus merkusii) and mangium (Acacia mangium), on the media for the growth of Eucalyptus urophylla and Acacia mangium seedlings up to 4,5-month period, respectively. The main objective of this research trial was to assess the effect of applying wood-bark charcoal on the growth of the seedlings. The two kinds of wood-bark charcoal were added at varying concentrations, i.e. 10%, 20%, 30%, 40%, and 50 percent, and 0% as control.The research revealed that the use of both kinds of wood-bark charcoal at 10-30 percent turned out to he the most optimal or suitable for the growth of the two seedlings. For height growth of Acacia mangium seedlings, the best effect was at the application of 10 percent tusam's wood-bark charcoal, where the height increase in the Acacia mangium seedling reached 13.01 percent. i.e.1.9 times greater than the height growth of the control. About the increase in the diameter of the seedling, the best effect was at 10 percent and 20 percent of either tusam's or mangium's wood-bark charcoal. Such diameter increase were almost similar i.e. 0.45 cm and 0.42 cm for tusam's and mangium's wood-bark charcoals, consecutively.For the height growth of Eucalyptus urophylla seedlings, the best effect was at the application 20 percent of tusam's wood-bark charcoal and 30 percent of mangium's wood bark charcoal. The height increases were at 20 percent tusam's wood-bark charcoal and 30 percent mangium's wood-bark charcoal, i.e. consecutively 1.38 and 1.35 times greater than that of the control. Similar phenomena as occurred to in the height increase in Eucalyptus urophylla seedlings also found in the diameter increases of the corresponding seedlings. In this situation, the height increclse was 0.56 cm. The use of tusam's wood-bark charcoal at JO percent offered the best effect on the growth development ofE. urophylla and A. mangium seedlings, i.e. 0.913 grams and 0.496 grams, respectively.
