Abstract

Limbah serbuk gergaji dan sebetan dari industri penggergajian kayu rakyat secara teknis dapat digunakan sebagai bahan baku untuk produksi arang dan cuka kayu secara terpadu karena kualitas produk masing-masing memenuhi SNI dan Jepang.  Limbah sebetan yang diproduksi pada tungku kubah batu-bata yang dilengkapi dengan unit pendingin air  menghasilkan rendemen arang 33,6% dan cuka kayu 40,6%. Analisis financial limbah sebetan menunjukkan jangka waktu pengembalian investasi dapat diperoleh setelah 32,9 bulan, tingkat bunga maksimum 79% dan besarnya nisbah manfaat terhadap biaya 1,08. Oleh karena itu hasil penelitian produksi sebetan ini layak dikembangkan pada usaha skala kecil. Limbah serbuk gergaji tidak layak dikembangkan karena investasi lebih tinggi dari nilai hasil produksi. Berdasarkan analisis financial arang sebetan dapat digunakan untuk bahan baku arang aktif yang diproduksi pada tungku arang aktif model pedesaan dengan menggunakan kayu bakar sebagai sumber energinya layak dikembangkan secara komersial, dengan jangka waktu pengembalian investasi dapat diperoleh setelah 35,8 bulan, tingkat bunga maksimum sebesar 13% dan besarnya nisbah manfaat terhadap biaya adalah 1,003. Pemanfaatan cuka kayu pada budidaya tanaman padi diperlukan sebanyak 40 liter/ha dapat memberikan keuntungan usaha pada petani sebesar Rp 9.980.500.- per ha sedangkan tanpa cuka kayu Rp 6.761.500.- per hari.

Abstract

Arang dengan strukturnya yang porous memiliki kemampuan menyerap polutan dalam fase cair maupun gas, walaupun tidak sebaik arang aktifnya. Saat ini papan serat kerapatan sedang (medium density fiberboard/MDF) merupakan salah satu produk panel kayu yang berkembang pesat. Pada penelitian ini arang yang ditambahkan dalam pembuatan MDF direkat menggunakan resin urea formaldehida dan dibentuk dengan proses kering, dimana bahan baku serat yang digunakan untuk pembuatan MDF merupakan campuran pulp TMP kayu mangium dan karet pada perbandingan 3:1 (b/b). Sementara itu arang yang digunakan diperoleh dari hasil karbonisasi campuran pulp TMP tersebut. Penggunaan arang dalam pembuatan MDF diharapkan dapat meningkatkan kemampuan daya serapnya. Pada pembuatan MDF, digunakan campuran serat dan arang pulp TMP pada beberapa komposisi yaitu 100:0, 90:10, 80:20 dan 70:30 berdasarkan berat kering. Pengamatan dilakukan terhadap kemampuan daya serap MDF terhadap uap atau gas benzena, kloroform dan formaldehida serta menguji sifat fisik, mekanik dan emisi formaldehidanya. Hasil penelitian menunjukkan bahwa semakin banyak jumlah arang yang digunakan ternyata mampu meningkatkan daya serap MDF terhadap gas yang diuji namun menurunkan sifat fisik dan mekaniknya. Sifat fisik dan mekanik papan serat dengan penambahan arang 10% relatif sama dengan MDF kontrol dan telah memenuhi standar JIS tipe 25 kecuali untuk keteguhan lentur (JIS tipe 15) dan keteguhan rekat internalnya. Penggunaan arang juga mampu memperlambat keluarnya emisi formaldehida dari MDF.

Abstract

One of  the drawbacks using plywood bonded with urea formaldehvde ( UF) is formaldehyde emission, especially in a room with limited ventilation such as mobile homes. Some countries have imposed restriction on the  limit of formaldehyde emission for certain uses.This work deals with the effect of  hardener and extender types on formaldehyde emission and on bonding strength of  the UF bonded plywood.The effect of  hardener mixed with catching agent on formaldehyde emission is positive,  i.e.   lower the formaldehyde emission at the same time lower the bonding strength.   The effect of extender types were not significant.  The interaction between hardener types and extender types were highly significant. This effect, however,  was not consistent since its effect on the bonding strength was highly significant in one type of hardener only.

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.

Abstract

One of the problems faced in mangium (Acacia mangium Willd.) wood utilization is its low drying rate. Some pre-treatment methods: steaming, boiling and microwave heating have been examined to improve its drying time. After treated with steaming, boiling and microwave heating, six various dimension of mangium samples were dried in oven. During drying process, the samples were weighed two hoursly in the first 24 hours to determine the pattern of moisture reduction. Microwave heating and boiling enhance its drying time in all sample sizes, while steaming was only effective for samples with thickness below 5 cm. Boiling leads to generate drying defects such as wrapping, twist, bow, and surface checks, while microwave heating and steaming methods caused minor drying defects.
