Abstract

One possible way to improve the value added of low quality agarwood (medang, sapuan, sabak) is by refining it to produce oil.Gaharu oil is used as raw material for several products such as raw material for perfumes, cosmetics and traditional medicines.This agarwood refining research aims to determine the oil yield, by products, to analyze the maximum cost, income and profit duringone refining period in the household-scale refining industry. This research was conducted in the household scale agarwood oil refiningindustry located in Rempanga Village, Loa Kulu Tenggarong Subdistrict, Kutai Kartanegara Regency. The results of this studyare expected to provide motivation to various parties to be able to utilize the quality of low-quality cultivated agarwood efficientlyand optimally through product diversification by refining it to produce high-value agarwood oil. The observation procedure is carriedout directly during the distillation process. Economic value is obtained by analyzing break even point (BEP) and maximum income.The results showed that the yield of agarwood oil was 0.07%. At the level of agarwood oil production of 30 mililiter (ml) per oneproduction period with a selling price of Rp 250,000/ml will break even if the agarwood oil produced is 1.93 ml with a value ofRp 482,159.88 or Rp 16,071.99/unit (ml). The business profit at the production level of 30 ml of agarwood oil is Rp 3,616,830(without sales of powdered waste and agarwood hydrosol) and Rp 8,316,830 (with sales of powdered waste and agarwood hydrosol).

Abstract

High consumption of fossil fuel causes energy crisis since its reserve is decreasing. This fact stimulates many studies to find out alternative energy as fossil fuels substitute. Bioethanol is considered as one of the most important source of alternative energy extracted fromplants.This research is aimed to provide tool engineeringrequired in producing bioetanol from Nypa fruticanssap. The engineering is consisted of two reactors. The first reactor can be used for pasteurization, sacarification and fermentation. The important second reactor is used as a distillation unit. The tool engineering has important advantage by using SSF (Simultaneous Sacarification and Fermentation) technique. By using this technique, processof pasteurization and fermentation can be carried out in onereactor. However the low levelof bioethanol flow rate becomes the weaknessof this tool . Theyield of Nypa fruticanssap was about 13.5% and the bioethanol contentof 70-94.5% with an averageof 84.8%. The yield of bioethanol distillation can be improved through the dehidration process. Bioethanol content can be increased from 94.5%to 98.5% by the dehidration process.

Abstract

Nipah (Nypa fruticans Wurmb.) produces sap that can be obtained by tapping process from fruit stem. In fresh condition of nipah sap taste sweet cause of including relatively high of sugar. This liquid is a fertile medium for the growth of microorganisms, so that nipah sap is potentially used as a raw material to produce nata. Nata is a food that classified in food dissert. Experimental of nata fruticans production bold by fermenting process used fresh nipab sap that with sugar in level of 0, 50, 75 and 100 g/l of nipah sup. By using fresh nipah sap that add with sugar in vary level yielded nata fruticans with producing recovery an average of 86.05% (76,52-90,97%). The addition of sugar in the fresh nipah sap is not affect significantly on the producing recovery of nata fruticans. Using fresh nipah sap without sugar addition yielded nata fruticans with producing recovery an average of 83,74%.

Abstract

The domestic need for phenolic-based wood adhesives is high, but the material is currently imported, then altenative adhesivesare needed. This paper studies the characteristics of mahogany tannins and effective formulation of alternative adhesives made frommahogany bark extracts of mixture tapioca flour and industrial flour as extender applied to composite or glued products. The barkof mahogany was cut to the size of 2 cm x 1 cm x 0.1 cm, extracted with hot water (70–80°C) with a ratio of 1:3 (w/w,material/water) for 3 hours with two repetitions. After extraction product was filtered, and the filtrate was copolymerized usingresorcinol and formaldehyde under alkaline and room temperature conditions to produce resin tannin resorcinol formaldehyde(TRF). The blend of tapioca flour and industrial flour (1:1, w/w) as an extender was used in the TRF application to manufacturecomposite products. The results showed that this mahogany bark liquid extract could be copolymerized to form a resin which thenapplied as a wood adhesive in a cold pressing process. The optimum adhesive formula was a mixture of 0.25 mol of resorcinol and1-mol formaldehyde, with a 15% extender, and a catalyst (NaOH 40%) of 4% of the total weight of the adhesive formulation.The characteristics of mahogany tannin adhesives resemble those of the exterior type phenolic group.

Abstract

Nowadays, the potency of conventional fibrous materials (ie, woods) for the manufacture of medium-density fiberboard (MDF) becomes depleted and scarce. Use of alternative fibers which are abundantly available and still largely unutilized, i.e. nypha midribs and coconut coirs, bas been attemped for MDF (medium-density fiberboard), using urea-formaldebryde (UF) adhesive However, such study showed that MDV from each of the two fiber sources could not satisfy the JIS and ISO standards. In relevant, improvement trial on MDF properties was accomplished using both kinds of fibers. Intially, those fiber stuffs had their basic properties examined, i.e. specific gravity, chemical composition, and fiber dimensions and their derived values. The MDF's fibrous pulping employed a bat semi-chemical soda process under atmospheric pressure at two alkali concentrations (8% and 12%). The resulting pulps were then added with additives, i.. 5% alum, 5% tannin formaldebryde (TF) adbesive either incorporated with activated charcoal (5%) or not; and then shaped into MDF mat using wet process, Physical-strength properties and formaldebryde emission of the resulted MDF wery examined. Assessing those properties, nypa-midrib fibers were more prospective for MDF than coconut-coir fibers, Activated- charcoal addition lowered MDF's formaldehyde emistion and improved dimensional stability, but decreased its strengths. In properties, MDF, from nypa fibers 100% were significantly the closest in satisfying the standard (JIS and LSO). Yet, coconut-enir fibers could still be prospective for MDF by missing them (pulp form) with wypa-fiber pulp at the propertion (w/w): 25%+75% and 50%+50%. The MDF with TF adhesive afforded better properties than the previous experiment (UF), n. greater strengths, lowered emotion and satisfying more of the 115 and ISO standard.

Abstract

Overtapping of pine resin in terms of quare size which is too wide and deep and the use of anorganic stimulant may cause tree damage and increase the risk of tree to fall. Modification of tapping technique may reduce the damage of trees and increase the production of pine resin. The modification should consider several aspects of economical, ecological, social, and technical. The objectives of the research were to determine the width and number of quare on each tree, the appropriate type of organic stimulant, and also cost analysis of the modified tapping technique. The results showed that different type of tapping such as width and number of quare per tree significantly gave different resin production. However, different types of organic stimulant and its interaction with number and width of quare was not correlated significantly with resin production. Modification of tapping techniques and the use of organic stimulant had direct influences on the cost and profit.
