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

Bintaro seed is widely used as an alternative raw material for biodiesel and waste the fruit-shell. This paper studies the utilization of fruit-shell waste for activated carbon. Activated charcoal was relied on two factors, namely chemical activator (H₃PO₄ concentration) and activation time of hot steam. Activated charcoal quality was tested against Indonesian National Standard (SNI 06-3730-1995). Results show the best activated charcoal is the treatment using H₃PO₄ 15% and 90 minutes hot steam. The process produce activated charcoal quality of 9.98% moisture content, volatile matter 9.16%; ash content 12.45%; fixed carbon 78.4%; adsorption on iodine 784.498 mg/g adsorption on benzene 17.73%; and adsorption on methilene blue 127.705 mg/g. The adsorption mechanism is similar with those adsorption of Langmuir isotherm with linearity of 0.9691. In term of improving water quality the best activated charcoal should be able to reduce the concentration of Fe in the water by 100 % and Mn by 86.94 % respectively.
