Abstract

Abstrak: Penelitian bertujuan untuk mengetahui pengaruh metode dan konsentrasi bahan pengawet Crown 100 EC dalam pengawetan kayu Sengon (Paraserianthes falcataria (L) Nielsen) terhadap nilai retensi dan ketahanannya terhadap rayap tanah (Subterranean termites). Seluruh data diolah menggunakan pola faktorial acak lengkap 4x3 dengan 10 kali ulangan. Parameter yang diukur adalah retensi dan uji ketahanan terhadap rayap tanah (Subterranean termites) dengan metode pengawetan pencelupan, penyemprotan, pemulasan dan perendaman dingin dengan konsentrasi 0,5%, 1% dan 2%.Hasil penelitian menunjukkan bahwa rataan kadar air kering udara diperoleh nilai sebesar 11,42%, kerapatan kering udara diperoleh 0,36 g/cm3 dan kerapatan kering tanur diperoleh nilai sebesar 0,33 g/cm3. Konsentrasi bahan pengawet Crown 100 EC, metode pengawetan dan interaksinya berpengaruh sangat signifikan terhadap nilai retensi bahan pengawet. Metode pengawetan dengan konsentrasi bahan pengawet yang tinggi dan waktu kontak yang lama maka nilai retensi yang dihasilkan semakin tinggi. Nilai retensi terbesar pada proses perendaman dingin dengan konsentrasi 2% dapat menghasilkan nilai retensi sebesar 0,9133 kg/m3 sedangkan nilai retensi terkecil pada proses penyemprotan dengan konsentrasi 0,5% menghasilkan nilai retensi sebesar 0,0389 kg/m3. Secara umum metode dan konsentrasi memenuhi standar retensi yang dipersyaratkan Standard New Zealand (NZ S3640)-2004 dan Standard Australia (AS1640)-2004, untuk perlakuan M1K2,M1K3,M2K3,M3K3,M4K1 dan M4K2 memenuhi standar harzard level H1, sedang untuk perlakuan M4K3 memenuhi semua standar harzad level H1,H2 dan H3. Kecuali pada perlakuan M1K1,M2K1,M2K2,M3K1 dan M3K2 tidak memenuhi standar harzard level (NZ S3640-2004 dan AS1640-2004).

Abstract

Woods are easy to ignite by fire. Increasing fire resistance with fire retardants is needed to increase safety and reduce losses due to fire. This research aimed to determine the fire resistance of Sengon wood treated with preservation of borax with a concentration of 5%, 10%, and 15% by cold immersion for five days. The fire resistance test used the ASTM E69-02 standard, while the statistical analysis (ANOVA) of the test data used a Completely Randomized Design at the 95% confidence level and the LSD test (Least Significant Difference test). The results showed of the physical properties of Sengon wood, the average value of air-dry moisture content was 14.08%, air-dry density was 0.33g/cm3, and oven-dry density was 0.30g/cm3.  In contrast, the LSD test showed a significant difference between the controls to the all-borax preservation treatments, but between 5%, 10%, and 15% borax treatments were not significantly different. The best fire resistance parameter values ​​were found in the 15% borax treatment, with the retention of 38.04 kg/m3, burning intensity 12.58%, combustion time 437.5 seconds, and effectiveness of 4.76. The fire resistance effectiveness value of all equipment cannot meet the ASTM E69-02 standard

Kalimantan mempunyai banyak jenis pohon yang belum dikenal secara luas pemanfaatannya. Tujuan penelitian ini adalah untuk mengetahui sifat-sifat fisika dan mekanika kayu ipil (Endertia spectabilis Steenis & de Wit Sidiyasa) berdasarkan letak ketinggian dalam batang agar kayu ipil dapat dimanfaatkan secara optimal. Hasil penelitian menunjukkan bahwa berdasarkan letak ketinggian dalam batang, sifat fisika dan mekanika kayu ipil meningkat mulai dari ujung batang hingga ke bagian pangkal batang. Berdasarkan Klasifikasi Kayu Indonesia, kekuatan mekanika kayu ipil termasuk kategori kelas kuat 1.

Abstract

The results of this study indicate that the average value of air dry moisture content of sengon wood is 14.081%, the air dry density is 0.326 g/m3 and oven dry density is 0.295 g/m3. The highest average retention value was at 3 days immersion with a concentration of 7% i.e. 16.161 kg/m3 and the lowest was at 1 day immersion with a concentration of 3% i.e. 5.161 kg/m3. The highest value of burn intensity at 2 days immersion with a 3% concentration i.e. 16.249% and the lowest at 1 day immersion with a concentration of 7% i.e. 6.025%. Preservation of sengon wood using natrium silicate at a concentration of 3%, 5% and 7% and immersion for 1 day, 2 days and 3 days is less effective in holding the fire rate, because the value is still below the ASTM E69 standard (2002) i.e. 7.5. The effective test of preservative (W) obtained the highest value of burn intensity at 1 day immersion with a concentration of 7% i.e. 7,490 and the lowest value at 2 days of immersion with a concentration of 3%, i.e. 3,231. The maximum temperature ranges from 206.0-291.2°C and the cooking time ranges from 206.1-607.8 seconds.

Abstract

Potensi kayu-kayu non komersil yang tumbuh di lahan terlantar maupun hutan sekunder selama ini belum dimanfaatkan dengan optimal. Termasuk diantaranya informasi dari jenis cepat tumbuh seperti kayu pangsor (Ficus callosa Willd) dan bayur (Peterospermum javanicum) sifat fisika dan mekanika yang tersedia dari kayu tersebut belum lengkap. Karena itu tujuan dari penelitian ini adalah untuk mengetahui hubungan antara nilai kerapatan kering tanur dengan besarnya nilai penyusutan kayu dan sifat mekanika kayu. Sehingga dalam penelitian ini diambil kayu pangsor yang mempunyai berat jenis kelas kuat V dan Bayur dengan kelas kuat III yang diambil pada bagian pangkal, tengah dan ujung batang. Pembuatan sampel dan pengujian sifat fisika mekanika kayu menggunakan standar Jerman (DIN). Analisis data korelasi dibantu dengan program Microsoft Exel. Hasil penelitian menunjukkan bahwa pada kayu pangsor dan bayur terdapat hubungan korelasi positif antara kerapatan kering tanur dengan penyusutan volume maksimal, keteguhan tekan sejajar serat dan MoE dengan sifat hubungan yang lemah.

Abstract

This research aims to determine the quality of cement-bonded particleboard based on variations in pressure from a mixture of jabon (Anthocephalus cadamba Miq.) and rice husks with a ratio of 50:50 at board density target of 1 g/cm3. The pressure variation was 20, 25, and 30 bar for 4 hours, while the catalyst used was Ca(OH)2. Physical and mechanical properties testing including density, moisture content, water absorption, thickness swelling, MoE, MoR and IBS tests referring to International Standards ISO 8335: 1987 and British Standards BS 5669: 1989. The test results show better quality trends at higher pressures and have met both standards on the physical properties, whereas mechanical properties does not meet both standards.

Abstract

This study aims to analyze the comparison of the adhesive shear strength value of the treatment used in the test sample, namely the difference in the type of adhesive with the difference in surface treatment of the adhesive plane. Analysis of variance (ANOVA) and LSD (Least Significant Difference) further test. The results of the analysis of variance showed that the effect of adhesive type (A) and surface treatment (B) on the adhesive shear strength of the laminate was very significant, while the interaction (AB) was not significant. Tests of physical and mechanical properties of laminated wood were carried out based on the JAS 234 - 2007 standard. The average moisture content of laminated timber was 11.59% and the average normal density was 0.329 g/cm³. The value of adhesive shear strength with A1 (epoxy) treatment of 69.79 kg/cm2 is greater than A2 (PVAc) of 63.98 kg/cm2 , while B3 (sanding) with the highest average of 72.86 kg/cm2 followed by B2 (planing) of 65.42 kg/cm2 and the lowest B1 (sawing) of 62.38 kg/cm2 . For the percentage of wood damage in the A1 (epoxy) treatment of 76.30% is higher than A2 (PVAc), while the treatment while B3 (sanding) with the highest average of 76.55% followed by B2 (planing) of 72.80% and the lowest B1 (sawing) of 71.00%, and has met the standard of JAS 234: 2007 (>54 kg/cm²).
