Development of the rattan furniture industry today is quite fast although the amount of raw materials are decreasing, especially in commersial rattan commodities such as Manau, Irit, Taman, Sega, etc. Their price is quite expensive too five species of rattan were used as research materials. There are Manau (Calamus mettanensis Becc), Toho (Calamus sp), Galang (Daemonorops verticilaris Griff Mart), Hijau (Calamus sp) and simpurut (Calamus panajuga Becc). For finishing materials, clear glass melamine (ML 131 and NC 141) were used in this research with three different immersion timer for 24 hours, 36 hours and 48 hours long. An immersion method without using any finishing materials was done as control materials. Result show that the average of volume expansion of rattan speseis using NC 141 are 1,56-3,16% in Marau; 1,36-2,91%; in Toho; 2,01-3,05% in Galang; 2,12-3,20% in Hijau and 1,90-2,14 in Simpurut. In the other hand, the average of volume expansion of rattan species using melamin ML 131 are 1,27-2,58% in Marau; 1,46-2,51% in Toho; 2,30-3,23% in galang; 1,10-2,79% in Hijau and 1,45-2,55% in Simpurut. In control materials the average of expantion volume in 5 species rattans is 2,53-3,99%. From those results, the best method was shown in using NC 141 which can prevent the volume expansion and give great influence in volume expansion value.Keywords: rattan, finishing material, melamine ML 131, melamine NC 141, volume expantion.

The purpose of this research is to exploit the waste ripsaw as substitution of gypsum board on the fhysical of board gypsum. Raw material in the form of waste saw from particle of wood kambang (Goniothalamus Sp), wood tarap (Artocarpus Elasticus REINW) and wood lua (Ficus Glomerata ROXB) size of particle 40 mesh and 60 mesh, while preservative use the ammonium of concentration borax 1% and 2% percentage gypsum to ripsaw particle 300, 400 and 500%. Research result show the rate mean irrigate to range from 10,02-14,61%, closeness 0,72-0,98 g/cm3, absorpsion irrigate 19,98-28,15%, thick development 0,95-1,93% and linear development 0,12-0,60%. As a whole examination of nature of fisis of board gypsum fulfill the standard of quality of board of gypsum SNI 03-6434-2000 except to rate examination irrigate and linear development not fulfilled the standard quality of gypsum board. Pursuant to this research result can be considered by industry gypsum to exploit the waste saw as substitution in making of board gypsum to be improve repairing the nature of rate irrigate and linear development.Keyword : waste powder ripsaw, lua, kambang, tarap, gypsum

The purpose of this research is to know the mechanical strength of gypsum board by utilizing waste sawn wood. Raw materials used consist of flour, gypsum,wood particles, boraks and kambang (Goniothalamus sp), wood tarap (Artocarpus elasticus REINW) and lua (Ficus glomerata ROXB). Wood particle 40 mesh and 60 mesh, concentrations boraks of 1 and 2 and the percentage particles of gypsum sawn timber is 300, 400 and 500%. The results showed that the average value Modulus of Rufture (MoR) in lua wood ranges from 12.55 – 14,47 kgcm2, wood kambang 25.10-31,11 kgcm2 and wood tarap 19.20- 24,18 kgcm2. As for Modulus of Elasticity (MoE) on the lua 1129,80- 2092,70 kgcm2, wood kambang 2512,37-3971,32 kgcm2 and tarap 2050,63-2691,09 kgcm2. Gypsum board are mechanical properties do not meet quality standards created SNI 03-6434-2000.Keywords: sawdust, lua, kambang, tarap, gypsum, mechanical

Aplikasi ekstrak sarang semut sebagai senyawa antimikroba dan antioksidan pada permen karet herbal [Application of ant nests (Myrmecodia sp.) extract as antimicrobial and antioxidant compounds in herbal gum] Nadra Khairiah; I Dewa Gede Putra Prabawa; Saibatul Hamdi; Nazarni Rahmi

Ant nests (Myrmecodia sp.) are one of the medicinal plants that have many benefits for health. Ant nests are widely used as antimoicrobial, antidiabetic, anticancer and antiimplantation because ant nests usually contains chemical compounds such as flavonoids, terpenoids, saponins and polyphenol tannins. Flavonoids can be used as antioxidants, antiangiogenic, and antimicrobials. Many products can be developed from the extract, such as tea, powder and ant nest capsules. Another product innovation that needs to be developed is gum. It is important to conduct research to determine the optimum formulation of ant nest extract as an additional ingredient on candy products (gum). This study aims to determine the antimicrobial and antioxidant activities of ant nests extract and maximize the use of ant nest extractas at additional raw material for high quality gum. The ant nests were extracted using 70% ethanol. The concentrated extract was tested for antimicrobial activity in four types of pathogenic bacteriaEscherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538, Streptococcus mutans ATCC 25175, Pseudomonas aeruginosa ATCC 9027, and Salmonella typhimurium ATCC 14028); antimicrobial positive control was tested using chloromphenicol and antioxidant activity positive control was tested with ascorbic acid (vitamin C). Dried ant nest extract was added to the gum mixture as much as 0.15% and 3% and then the quality was tested based on the parameters according to the quality standard of gum. The results of this study showed that ant nest extract had effective antibacterial activity in gram-positive and gram negative bacteria with an inhibitory zone of 10-13.5 mm. The high antioxidant activity of ant nests (85.90%) proven that ant nests had the potential as an natural antioxidants added in food. The addition of 0.15% and 0.3% extracts in chewing gum generally produced gum that met the quality standards of chewing gum, although the moisture content was slightly higher than the maximum limit of the standards.

The activated carbon is very important for has processed product activated carbon. In south Kalimantan has a big prospects due to the big potential of the raw material provided by the nature and industrial waste. There are a lot of raw materials that can be used for the manufacture of activated carbon such as agricultural waste, sugarcane waste, waste of sawn timber, lives stock waste and coal processing waste.Manufacture of activated carbon can be done in ways: chemical and physical processes. Activation is very important in the manufacture of activated carbon in addition to the raw materials used. Activated carbon is charcoal that has undergone changes in chemical properties and physical properties due to be activated with the activator chemical materials or can by heating at high temperatures, so that absorption , surface area, and the ability to absorb become as very good. Activated carbon is used as an absorbent to absorb heavy metals, in medicine and food, on liquor, petroleum chemical, shrimp farming, the sugar industry of gas purification, catalyst and fertilizer processing.Key wood : technology processed, activated carbon
