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

The presence of invasive species is often seen as environmental and economic problem. On the other hand, the potential of these species which have fast growing and regeneration ability can be used for various purposes such as alternative bioenergy utilization. This study is aimed to observe the wood anatomical and energy characteristics of invasive species such as Melastoma malabathricum, L., Calliandra callothyrsus, Meissn and Acacia mangium, Willd. It is potentially utilized as source of alternative energy. This study used purposive sampling method, and used wood samples with the thickness of about ≥5 cm. This research was analyzed descriptively for anatomy characteristic whereas the diameter and frequency of vessel, heigh and width of parenchyma then calorific value, ash and moisture content analyzed using Kruskall Wallis and Mann Whitney. Anatomical characteristic of wood from two species were diffuse porous vessel, solitary and multiple vessel, frequency of vessel were rare to many and diameter of vessel were small to rather small and paratracheal axial parenchyma. Rays were uniseriate or biseriate with 1-3 seriate, height of ray category was extremely short and width rays were narrow to extremely narrow. All rays were homorocelular with upright or procumbent cells. The calorific value of these species started from 3,887.59 to 4,132.99 kal/g. Ash content start from 1.27–1.73% meanwhile the moisture content were 11.6–12.6%. Base on energy properties, Calliandra callothyrsus, Meissn. fulfilled the standard of bio pellet production base on SNI 8021 and EN- 14961-2.

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.

Abstract

Candlenut wood is one of low quality wood species in term of strength and durability class of V-IV, so its utilization is limited. Efforts to improve physical and mechanical properties of wood are required. One way is using wood modification technology by oil-heat treatment. This research aim was to analyze the changes in physical and mechanical properties of candlenut wood after heating with oil. The stages of this research were sample pre-treatment, heating treatment and wood testing. Samples were pre-treated by heating gradually at 60°C and 90°C for 24 hours to avoid crack during treatment. The heat treatment was applied at several variation of temperatures, namely (160, 180, and 200)°C for 1 and 2 hours, respectively. Properties of wood were tested according to modified ASTM D143-94 standard. The Completely Randomized Design was used to determine effect of heat temperature and time on the wood properties. The results showed that heating with oil on candlenut wood gave a positive response, as evidenced by an increase in physical and mechanical properties of wood. Oil-heat treatment could be an effective method for improve properties of  wood. The increases of specific gravity, MOE and MOR were ranged from (16.49 to 26.62)%, (1.25 to 13.61)%, and (4.37 to 10.15)%, respectively. The use of 160°C increased properties of wood with relatively higher compared to other temperatures in 1 hour. Longer heating times tend to reduce properties of wood.
