The availability of organic ameliorants is very important to induce seedling growth. This study examines the effect of various organic ameliorant addition into the growth of kemenyan seedlings (Styrax benzoin Dyrand), trembesi (Samanea saman Jack. (Merril.) ) and ki bawang (Melia excelsa Jack). The addition of organic ameliorants were grouped into 11 different treatments: (p) soil (control); (q) charcoal organic fertilizer (POA) 10%; (r) POA 10%+ charcoal sawdust (ASG) 5%; (s) POA 10% +ASG 10%; (t) organic fertilizer tablet of charcoal and mycorrhiza (POAM); (u) organic fertilizer tablet of mycorrhiza (POM); (v) POM + ASG 5%; (w) wood vinegar (CK) 1%; (x) CK 1% + ASG 5%; (y) CK 2%; (z) CK 2% +ASG 5%. The Results showed that treatment r, the use of 10% charcoal organic fertilizers (POA) and5% charcoal sawdust (ASG) affected most significantly to the height increments. The analysis of variance showed that the various treatment of ameliorant addition affected significantly to height increments but did not have significant effect to the diameter increments.

Smoke liquid is a liquid obtained from smoke condensation during charcoal firing process. The main content of the smoke liquid is acetic acid, hence, can be used as an alternative latex coagulant. Acid in vinegar can reduce the pH of latex and cause the latex to coagulate rapidly. This paper determines effectiveness of using smoke liquid as a latex coagulant and characteristics of the treated latex. The smoke liquid in this study was derived from pine wood. The smoke liquid solutions consisted of the crude smoke liquid and the diluted solution in various concentrations of 5, 10, 15 and 20%. The smoke liquid solution was then each poured into a container of latex. Testing was undergone by observing latex coagulating time, coagulate condition, texture, color, odor and homogenity. The most effective smoke liquid which produced the best latex based on its performances was then taken for further testing of physico-chemical properties which included dry rubber content, plasticity retention index (PRI), initial plasticity (Po), final plasticity (Pa), dirt content, ash content, volatile matter content (Vm), and nitrogen content. Results were then compared with the conventional use of formic acid as a control coagulant. The result showed that the crude and distillate smoke liquid solutions with concentration of 10% produced the best coagulantperformances than the other solutions. Rubber latex treated with the crude smoke liquid produced the best physico-chemical properties and could meet requirements of the Indonesian National Standard (SNI) for Rubber Quality.

Anatomical properties is necessary for wood species identification. This paper observes anatomical properties of six wood species originated from Papua. Wood species studied include: ketapang (Terminalia complanata K. Schum.); pala hutan (Gymnacranthera paniculata (A.DC.) Warb.); bipa (Pterygota horsfieldii (R.Br.) Kosterm).; kelumpang (Sterculia shillinglawii F. Muell.); manggis/kandis (Pentaphalangium parviflorum); and lancat/lebani (Mastixiodendron pachyclados (K. Schum) Melch.). Anatomical properties were observed according to IAWA (International Association of Wood Anatomists) checklist. The anatomical main properties observed in ketapang wood were vestured pits, prismatic crystals in non-chambered axial parenchyma cells, and druses. Pala hutan main anatomical properties were the presence of tannin tubes and oil cells which were associated with axial parenchyma. Prismatic crystals in axial parenchyma cells, and rays of two distinct sizes were two main anatomical characteristics of bipa and kelumpang wood. Prismatic crystals in chambered axial parenchyma cells was one of characteristics of manggis wood. Vestured pits and scanty paratracheal parenchyma were two main characteristics of lancat wood. For identification purposes, bipa wood could be distinguished by banded parenchyma; polygonal alternate pits; and prismatic crystals in nonchambered axial parenchyma cells.

Charcoal is a porous solid material which is resulted from combustion of material that containing the carbon element (C). Charcoal can be used as raw materials in the manufacture of batteries, charcoal briquettes, and charcoal compost, can also be further processed in to activated charcoal. This study aims to manufacturing activated carbon from Kemiri Sunan shell waste as raw materials, determining it's optimum conditions and physico-chemical properties. The results showed that Kemiri Sunan shell can be used as raw material for activated charcoal with the following qualities: adsorb capacity of iodine solution 138.46‑768.31 mg/g, adsorb capacity of benzene 2.99‑21.37 %, and adsorb capacity of methylene blue 18.239‑260.237 mg/g. The optimum conditions of manufacturing of activated charcoal is produced at temperature of 850 °C that are soaked in a solution of 10 % H3PO4 with steam activation time for 90 minutes results adsorb capacity of iodine and methylene blue which meets the technical requirements of activated charcoal in the Indonesian standard (SNI) number 06‑3730‑1995.

Cocoa butter has long been used as a base ingredient for lipstick. Illipe nut's fat is known to have similar characteristics to those of cocoa butter, thus expectedly, it could be used as an alternative substitute for cocoa butter in lipstik manufacturing. This paper studies the appropriate Illipe nut's fat formulation for lipstick manufacturing. Water-based (WB1, WB2, WB3, WB4) and oil-based (M1, M2, M3, M4, M5) formulations with illipe nut fat content of 2, 3, 4 and 5% were tested. The illipe nut's fat was produced from Shorea pinanga collected from West Java. Physical properties (i.e hardness and melting point) and organoleptic test (texture, shine, polish ability, odor and color) were analyzed. The results showed that M3 formulation with 2% illipe nut's fat level had similar physical properties to those of commercial lipsticks. Furthermore, the organoleptic test revealed that M5 formulation with 3% fat level was the most preferred by respondents. To obtain lipsticks performance which meets the requirements in commercial lipsticks criteria and also satisfies the respondent's preference, a combination of M3 and M5 formulation is recommended.

Mata kucing dammar has long become remarkable export commodity, most of which unfortunately is still in naturalform (chunk-shapped exudates) obtained from the tapping of its host trees (Shorea javanica). Accordingly, such dammarstill contains large amount of impurities thereby lowering its qualities or trade values. Consequently, this necessitates athorough purification attempt to enhance the dammar's added-value. The dammar purification prevalently uses organicsolvent. However, the market demand for the solvent-free dammar products currently tends to increase commensurate withthe advancement in dammar usage for drugs/ medicine and food industries. In relevant, purification of mata-kucingdammar was experimented using manual heating system, rather than organic solvent. Result revealed physico-chemicalproperties of the heat-purified dammar were not significantly different from those of natural dammar (without purificationtreatment) as well as of the solvent-purified dammar. Even, with respect to ash content (impurities) and toluene insolubility,the heat-purified dammar seemed to be better than the natural dammar. GC-MS analysis revealed there were five majorchemical compounds with relatively large contents in heat-purified dammar. Such phenomena were similar to those in thenatural dammar, with the contents of those compounds in the heat-purified dammar slightly higher.
