Abstract

Wood or lignocellulosic materials with high extractives are not recommended for making cement boards. Extraction of raw materials before the cement board manufacturing is a treatment carried out to address this issue. The aim of this research is to determine the influence of cold and hot water extraction treatment on Bamban particles on the quality of the cement boards. This research was conducted by immersion bamban particles on hot water (boiling at 100°C) for 3 hours. The mixture ratio between cement and bamban particles was 1.5:1 (w/w), and it was compressed for 1 hour at a pressure of 30 bar, followed by manual pressure (clamping) for 24 hours. The physical and mechanical properties of cement boards was conducted according to SNI 03-2104-1991 for wood-wool cement boards. The results of the study show that hot water extraction treatment has a very significant effect on the quality of the resulting cement boards.

Abstract

Limbah kayu yang berlimpah dapat mencemari lingkungan, perlu pengelolaan menjadi briket arang agar dapat dimanfaatkan dengan efisien dan sebagai alternatif energi terbarukan. Penelitian bertujuan untuk mengetahui karakteristik briket arang dari limbah serbuk meranti (Shorea spp) kemudian hasil pengujian akan dibandingkan dengan Standar Nasional Indonesia SNI 01-6235-2000 tentang briket arang. Metode yang dipakai dalam penelitian ini adalah Rancangan Acak Lengkap (RAL), terdiri dari perlakuan dengan perbedaan ukuran serbuk yaitu 20 mesh, 40 mesh, 60 mesh dan 80 mesh dengan ulangan 5 kali, sehingga diperoleh jumlah sampel pengujian sebanyak 20 sampel pengujian. Analisis data menggunakan Analisis Sidik Ragam. Hasil penelitian menunjukkan briket arang dari limbah serbuk meranti masuk dalam Standar Nasional Indonesia, kecuali pegujian kadar zat mudah menguap. Dilihat dari nilai rata-rata pengujian setiap sampel, yaitu nilai kerapatan 0,79 g/cm³, keteguhan tekan 3,07 kg/cm², kadar air 4,72%, kadar zat mudah menguap 27,85%, kadar abu 3,33%, kadar karbon terikat 63,90%, dan nilai kalor 7090,08 Cal/g.

Abstract

The aim of this research is to determine the influence of mixture rasio of cement/bamban particles on the quality of the cement boards. This research was conducted by four mixture rasio cement/bamban particles (w/w) that was 1.25/1, 1.5/1, 1.75/1 and 2/1. Bamban particles was immersion on hot water (boiling at 100°C) for 3 hours to remove the extractives compounds. The mixture ratio between cement and bamban particles was compressed for 1 hour at a pressure of 30 bar, followed by manual pressure (clamping) for 24 hours. The physical and mechanical properties of cement boards was conducted according to SNI 03-2104-1991 for wood-wool cement boards. The results of the study show that mixture rasio cement/bamban particles has a very significant effect on the quality of the resulting cement boards.

Abstract

Central Kalimantan has many types of wood such as Rengas (gluta sp), Bangkirai (shorea laevifolia endert), and Agathis (agathis spp). The third type of woods are found in the company of furniture as a result of waste in powder form so that it can be utilized for the manufacture of charcoal briquettes. The purpose of the research is to find out the characteristics of charcoal briquettes from wood waste Rengas, Bangkirai, and Agathis which refers to the Indonesian National Standard (SNI 01-6235-2000). The treatment of this research done on Bangkirai wood, Rengas, and Agathis which have different density with 5 replications so that the samples obtained 15 pieces. Data analysis was conducted to determine the effect of the treatment on the character of the studied and if it has significant effect then it is analyzed test difference average middle value that is specified by Coefficient Value of Diversity. Charcoal briquettes testing generally meets Indonesian National Standard (01-6235-2000) on charcoal briquettes except for volatile substances. The research data finding from these three types of wood which examined showed that the type of Bangkirai wood powder has the best charcoal briquette quality because of lower water content is at 5.05%, the higher density is 0.72 g/cm3, the ash content is 1.9% , carbon bound is 63.30%, volatile substance content is 29.75%, press firmness is 41.67kg/cm2, and calorific value is 6958.94 kal/g

Abstract

The shrinkage of wood and the dimensions of wood fibers in the radial positions of stem are two important factors in the use of wood. An understanding of the dimension of wood fiber and the shrunkage of the wood in the radial direction can guide the optimum use of timber. The purpose of this study is to determine the shrinkage and changes in the dimensions of the timber (Combretocarpus rotundatus Dans) in the radial direction. The method used refers to the British and IAWA standards. The parameters measured are the radial and tangential shrinkage of wood as well as the dimensions of the fiber. The t test is used to test statistically. The results obtained showed that the position in the radial direction of the stem had a significant influence on the tangential shrinkage of fresh-oven dry and the fiber dimensions of Tumeh wood. The tangential shrinkage of the near pith is lower than that near the bark. The nearest pith part has a shorter fiber length; a thicker fiber wall is thinner than the near bark but still in the same quality class (Grade III) Keywords: tumeh, combretocarpus rotundatus, shrinkage, fiber dimension, radial positions.
