Abstract

Kapok wood has high potential availability of wood. Although, the weakness is its low quality. However, kapok wood quality can be improved by compaction technology. This research aims to improve the physical and mechanical properties of wood with wood compaction technology, and to determine the effect of variations in the horizontal position of trees and the length of steaming on the mechanical properties of compacted wood. The method used was compaction method with steaming treatment. The study used three types of wood method variations, namely terrace wood, transition wood and sapwood and four types of treatment with steaming duration of 30 minutes, 60 minutes, 90 minutes and without steaming. Wood testing on the physical properties of wood was guided by JIS Z 2102 (1957) and JIS Z 2103 (1957), while the mechanical properties of wood testing was guided by JIS Z 2113 (1963). Research showed that compaction on stretched wood with a target thickness of upto 2 cm improved the physical and mechanical properties of compacted wood. Steaming treatment prior to pressing for 90 minutes was effective in improving the mechanical properties of wood. The mechanical properties values improved by the increasing time of the steaming time before pressing the wood. The variation of wood position/parts affect the enhancement of the mechanical properties of wood in the parallel compressive strength test.

Abstract

Abstrak. Lahan padi merupakan sumber terbesar dari emisi CH4 dan berkontribusi terhadap 12% total emisi tahunan. Salah satu cara untuk untuk mengurangi emisi gas metan adalah dengan pemberian arang. Tujuan dari penelitian ini adalah menganalisis pengaruh arang perendaman berbahan baku serbuk limbah kayu terhadap penurunan emisi gas metan pada lahan padi. Limbah serbuk kayu yang digunakan dalam penelitian ini berukuran 0,42-1,00 mm dan dipirolisis selama 2 jam pada suhu (350-550)oC. Arang yang dihasilkan (kondisi panas) kemudian direndam menggunakan air selama 30 menit. Arang hasil perendaman kemudian disaring dan dikering-udarakan. Tanah sulfat masam ditambahkan arang hasil perendaman sesuai dosis perlakuan. Perlakuan penelitian adalah (1) kontrol tanah, tanpa arang perendaman (K0); (2) 30 gram arang perendaman + tanah (K1); (3) 60 gram arang perendaman + tanah (K2); (4) 90 gram arang perendaman + tanah (K3); (5) 120 gram arang perendaman + tanah (K4); (6) 150 gram arang perendaman + tanah (K5). Pengamatan terhadap emisi gas metan dilakukan selama 30, 60, dan 90 Hari Setelah Tanam (HST). Untuk mengetahui pengaruh suhu dan perendaman arang terhadap kualitas arang yang dihasilkan serta mengetahui dosis arang terhadap emisi gas metan digunakan Rancangan Acak Lengkap. Hasil penelitian menunjukkan bahwa seiring dengan peningkatan suhu pirolisis, nilai pH, kadar abu, dan fixed-C semakin meningkat, sedangkan hidrogen dan oksigen menurun. Perendaman arang menghasilkan produk arang dengan pori-pori relatif lebih banyak dan terstruktur. Fluks metan menurun seiring bertambahnya dosis arang perendaman, yaitu 22,57 mg/m2/hari menjadi 9,73 mg/m2/hari pada 30 HST, 55,07 mg/m2/hari menjadi 13,40 mg/m2/hari pada 60 HST, dan 92,51 mg/m2/hari menjadi 19,59 mg/m2/hari pada 90 HST.Kata Kunci : arang perendaman; limbah kayu; fluks metan Abstract. Rice fields are the largest source of CH4 emissions and contribute to 12% of total annual emissions. Providing charcoal treatment is one way to reduce methane emissions. The purpose of this study was to analyze the soaked charcoal derived from wood waste to reduce methane gas emissions of rice fields. The sawdust used in this study was 0.42-1.00 mm and pyrolyzed for 2 hours at (350-550)oC. The resulted charcoal in a heat condition was then soaked using water for 30 minutes, filtered, and dried. The soaked charcoal was added according to the dosage given. The research treatments were (1) soil control, without soaked charcoal (K0); 30 grams soaked charcoal + soil (K1); (3) 60 grams soaked charcoal + soil (K2); (4) 90 grams soaked charcoal + soil (K3); (5) 120 grams soaked charcoal + soil (K4); (6) 150 grams soaked charcoal + soil (K5). Observations on methane gas emissions were carried out for 30, 60, and 90 Days After Planting (DAP). The Completely Randomized Design was used to determine the effect of temperature and soaking of charcoal on the charcoal quality and to determine the dose of charcoal on methane gas emissions.

Abstract

This manuscript presents the research on the machining properties of kumpang (Albizia sp.) wood, in particular wood surface smoothnes, which were tested at two moisture contents, 14% and 10 %, respectively. Machining properties was tested according to the modified ASTM D-1666-64 standard method. The machining properties observed were planing, shaping, boring, turning and sanding. The number of replications for each observation variable was five, so the total sampel test was fifty pieces. Visual observation was performed using loupe at 10x magnification. The results showed that kumpang wood with 10% moisture content had a higher values of defect-free machining properties than of wood with 14% moisture content. However, the moisture content significantly influenced only on boring and turning properties, whereas the properties of planing, shaping and sanding were not significantly different. Quality of planing, shaping and turning was good, while boring and sanding was very good. Kumpang wood could be recommended for processed wood products due to its good to very good machining properties.

Abstract

The total area of oil palm plantations in 2019 is 14.2 million hectares. Every 25 years, there is always oil palm plantations replanting that produced oil palm trunks. The potential of oil palm trunks used as raw material for laminated lumber is about 52.5% of the total of oil palm biomass. Oil palm trunks have a very low density, so that it needs special processing before it could be applied as building material or other uses. The purpose of this study is to analyze the physical and mechanical properties of laminated lumber from oil palm trunks at the end position based on the number of layers. The method used in this research was the utilization of oil palm trunks lamination using PVAc (polyvinyl acetate) adhesive with variations of 1, 2, 3, and 4 layers. The results showed that oil palm trunks could be used as raw material for laminated lumber. The characteristics of laminated lumber made from 1, 2, 3, and 4 layers range between: moisture content (12.16–13.6) %, density (1.281–0.331) g/cm3, MoR (65.46–116.54) kg/cm2, and compressive strength parallel to its fibers (43.31–114,66) kg/cm2. The physical properties of the oil palm trunks laminated lumber with the increasing number of layers tends to increase the density and reduce the moisture content, rather than oil palm trunks laminated lumber with a smaller number of layers. The increasing number of oil palm trunks layers lamination increase the value of laminated lumber mechanical properties.

Abstract

Methanolic extract of Java Plum (Syzygium cumini) seed (MEJS) have strong antioxidant activity by radical scavenging antioxidant-2,2 diphenyl-1-picrylhydrazyl (RSA-DPPH) assay, ferric ion reducing antioxidant power (FRAP), also strong in the inhibition of lipid oxidation in the linoleic acid emulsion system assay, but moderate on striped catfish (Pangasius hypothalamus) oil-in-water emulsions. Antioxidant activity of MEJS is relatively stable on thermal heating by oven until 130 oC/10 minutes, gamma ray’s irradiation up to 12.5 KGy and suitable application on pH 6-9 acidity. MEJS is potential as a natural antioxidant in food system. However, must be carried out further assay the effectiveness of its use in commercial edible oil. The purpose of this research was to analyzed the effect of the addition of MEJS 200-1000 ppm against inhibition of lipid oxidation in an emulsion system. Research methods consisted of sesame seed oil extraction and analyzes of its a fatty acid profile, MEJS applied on sesame seed oil emulsion system to inhibit of lipid oxidation during 3 weeks storage. Assay variables were RSA-DPPH, the peroxide value  (PoV), TBARs value and the free fatty acids (FFA) values changes. The result showed that 35.85% Sesame seed oil yield consisted of 11.62% saturated fatty acids, 6.23 % mono unsaturated fatty acids and 85.95% poly unsaturated fatty acids. Applied of MEJS (200-1000 ppm) could increase of DPPH• radical scavenging stronger than both BHT 200 ppm and the control (sesame seed oil bulky), but didn’t correlative impact with inhibition autoxidation on it. Applied MEJS > 800 ppm comparable with BHT 200 ppm. MEJS as a natural antioxidant is not appropriate to apply for the oil in water of emulsion system.
