Abstract

Smoke liquid is a condensation product of raw material combustion containing cellulose, hemicellulose and lignin. Itproduces many compounds that have antimicrobial, antibacterial, and antioxidant effect such as organic acids and itsderivatives. Bintaro fruit shell is a waste of oil processing bintaro that are not utilized. Generally, latex coagulation usesformic acid or acetic acid that it's expensive and less environmentally friendly. Bintaro shell pieces is unused material andcontaining cellulose, hemicellulose, and lignin made into smoke liquid that is acidic and could reduce pH so the latex willcoagulate faster. The purpose of this study was to use smoke liquid of shell bintaro fruit shell as an alternative coagulant forrubber latex material.Smoke liquid wasmade using a modified drum kiln with a temperature of 400 C for 7 hours. Smoke liquid is purifiedby distillation up to 200 C. Smoke liquid that has been purified, further analyzed of its physical properties such as watercontent, viscosity, specific gravity, pH, acidity and phenol. Application of smoke liquid as rubber coagulant where doneusing smoke liquid concentration of 5%, 10%, 15%, 20%, while smoke liquid from coconut shell was used as acomparison. The results showed that the best results for coagulating was obtained from bintaro shell concentration of 20%and the fastest time for coagulating obtained from coconut shell smoke liquid concentration of 5%. Bintaro shell smokeliquid can be used as a rubber coagulant but for coagulation time isnot as fast as coconut shell smoke liquid.

Abstract

Composite products made of rattan have a decorative value and potentially can be developed for current market demand. Rattan laminated board is expected to perform effective as a substitution material for wooden furniture. The aim of this research is to determine technology of making laminated rattan board from large rattan species which having diameter of more than 30 mm using phenol based adhesive from organic resources, i.e. bark (mangium, mahoni) and merbau sawdust. The laminated rattan board sizing of 1.5 cm x 7.5 cm x 90 cm were made of five layers which spreaded on one side of the surface and hot pressed with 10 kg/cm2 specific pressure for three hours. Testing of rattan laminated board products includes bonding strength and formaldehyde emissions, and also the bonding strength value of samples from the National Rattan Innovation Center (PIRNas) as a comparison. Results show that bonding strength and formaldehyde emissions of the rattan laminated board was influenced by interaction type of tannin-formaldehyde, pressing temperature, and glue spread. The best quality adhesive performance of rattan boards was obtained on the use of tannin-formaldehyde mangium resin with formaldehyde emissions with a glue spread of 200 g/m2 surfaces and 100oC pressing temperature, with formaldehyde emmision within the safe limits. Approximately 28% of the experimental rattan laminated boards possessed bonding strength which exceeds bonding strength value of the PIRNas board, which used synthetic resin based on the imported phenolic adhesive.

Abstract

The formulation of phenolic compounds extracted from biomass not only produces adhesives but can also be used as bioimpregnant. In this study, the synthesis was carried out by copolymerization of resorcinol (R) and formaldehyde (F) into the oilpalm bark extract (S) to produce SRF resin fluid. A complete characterization was carried out using FTIR, Py-GCMS, XRDand DTA. In addition, F emission was also undertaken to ensure its safety for health and the environment. The application ofbio-impregnant was done on samples of the hard (edge) and soft (middle) parts of the oil palm trunk. The results show that the oilpalm bark extract contains polyphenol components that have a strong affinity for resorcinol and formaldehyde in alkaline catalyst(NaOH 40%), so that it can form a copolymer that can be used as an impregnant. The application of the bio-impregnant canimprove the quality of the oil palm trunk in both parts from class V to class III of wood-strength classification with an increase indensity (>100%), hardness (4 times), thickness swelling in both cold and boiling water meets the requirements (<25%), as wellas formaldehyde emission that meets the standard SNI 03-2105-2006.

Abstract

The world's demand for wood is increasing while the amount of solid wood production is decreasing with the depletion of forestsdue to illegal logging and conversion of forest functions as plantation land. To overcome these problems, it is necessary to do theefficiency of wood raw materials so that the use of solid wood can be reduced. One of the efficient ways to use wood raw materials isto utilize optimized wood industrial waste by combining one or more types of wood which are glued together into a single unit,commonly called a laminated board. In this study, we will look at the effect of different types of wood and the weight of the gluespread on the resulting laminated board. Advantages Laminate board can produce a board size that is wide and long as neededbecause the joints are made as long as needed. In the manufacture laminated boards are made with the type of wood, namely jatiputih (Gmelina arborea. Roxb), bajur (Pterospermum javanicum), sengon (Paraserianthes falcataria) and mixtures(jati putih, bajur and sengon) and the glue spread factor is 150 g and 200 g. Then the physical and mechanical properties weretested. The test results showed that the wood type had a significant effect on all physical and mechanical properties except for thethickness shrinkage and MoE tests. The interaction of the lamination glue spread factor and the wood type factor did not significantlyaffect all physical and mechanical properties of mixed wood waste laminated boards. Based on the test results, laminated board isclassified as strong class III which can be used as a lightweight construction material indoors.

Abstract

Rattan has the potential to be developed into composite products with gluing technology into laminated rattan. However, as araw material, rattan has a weakness, namely that it contains chemical components that inhibit the adhesive bond with the chemicalmolecules of rattan. In an effort to overcome this, a technique for making composite rattan was carried out in order to obtain dataon the effect of pretreatment on rattan as a raw material. Rattan as a raw material is first dried by microwave, hydrothermalevaporation and conventional methods in order to reduce the levels of adhesive chemical components contained in rattan. This paperpresents the results of research on the technology of making laminated rattan from the Batang (Calamus zolingerii) large diameter(>20 mm) with mangium tannin adhesive. The results showed that the pre-treatment of rattan as a raw material in the form ofdrying by means of oven, steam, frying, hydrothermal, and microwave, each produced a different effect on the chemical componentscontained and the degree of crystallinity. The best rattan laminate board was obtained from rattan which was pretreated using a 1kW microwave oven (input) with a maximum energy strength of 50%.

Abstract

Sago (Metroxylon spp.) is one of the native Indonesian plants that can be converted into biofuel or bioethanol. All parts of sago: starch, stem and midrib could be converted into bioethanol. The objective of this research is to determine ethanol production techniques made of pith and sago waste fiber using chemical and enzymatic methods. Bioethanol technique used was chemical based using hydrochloric acid solution (HCl) of 3.1; 6.2; 9.3 and 12.4% with substrate concentration of 15% (dw) and then heated by autoclave at 121–127 °C for 5, 10 and 15 minutes; pressure of 1–1.5 bar. The enzymatic method was undertaken using 0.15 ml alpha amylase enzyme and 2%, 3% and 4% cellulase. Fermentation was conducted using 0.21 g of urea addition, 0.12 g of NPK and 0.48 g of yeast for 4 days. Results showed that the pith yielded higher reducing sugar content and ethanol content than sago fiber waste either by chemical method (446.34 g/l, 51.65%) or enzymatic (15.39 g/l, 16.82%). Greater of cellulase concentration from 2% to 4% could not improve the yield of ethanol either made from pith or the wasted sago fiber through hydrolysis process.
