Abstract

Medang wood (Chinnamumum sp) and Bintangur wood (Calophyllum sp) was used for timber construction even they have low quality on the durability. The efforts need to improve their durability, especially against subterranean termites, the most destructive wood organism. One methods of preservation which can improve the durability was fumigation. Fumigation can be processed with traditional methods and modern methods.  The aim of the study was to improve the durability of Medang wood (Chinnamumum sp) and Bintangur wood (Calophyllum sp)with modern fumigation methods and evaluation the durability against subterranean termites Coptotermes curvignathus Holmgren. Wood sample was measured 2 cm x 2 cm x 1 cm. The fumigation treatment was conducted with oven. The oven size was 1 m x 1 m x 50 cm. Treatments of fumigation consits of 12 hours and 24 hours. The treatment of evaluation the durability agaisnt termites was conducted for 21 days. The wood sample was put on the bottle and 50 termites consist of 45 workers and 5 soldiers were put in the wood sample. The parameter of indicator was termite’s mortality and wood weight loss. Result of the research showed that average termites mortality was reach 100% at wood sample with fumigation method for 24 hours, and 89.2% for wood sample with fumigation method for 12 hours. Meanwhile in control wood the termite’s mortality only 8.6%. The level of termites mortality with fumigation methods for 24 hours was classified very strong and for fumigation methods for 12 hours was classified as strong. The average wood weight loss was 1.21% - 1.30%. This wood weight loss was classified as very low. From the research it is concluded that fumigation method can increased the durability of wood, both on Medang wood and Bintangur wood against the subterranean termites Coptotermes curvignathus Holmgren. The optimal fumigation methods was on 12 hours, both on Medang wood and Bintangur wood.Keywords: Calophyllum sp, Chinnamumum sp, Coptotermes curvignathus, fumigation, wood preservation

Abstract

There are several species of mulberry that grow and cultivated in Indonesia, and Morus alba var. kanva is one of it. The leaves of mulberry are used as silkworm feeds, while the bark and stem as waste are not utilized. This study aims to analyze the potency of bark and stem of mulberry as an antibacterial Enterococcus faecalis (E. faecalis) which is a cause of the infection of teeth root canal. The bark and stem of mulberry were measured it water contents then macerated with ethanol and the percentage of yield extracts were determined. Furthermore, anti-bacterial activites were conducted with 5 level concentrations of bark and stem extract (25; 50; 75 and 100 mg / mL), ethanol and Tetracycline 250 mg as negative and positive control. The results showed that the bark had a moisture content of 10.7% with a yield value of 25.5%, while the stem had a moisture content of 9.4% and a yield value of 9.8%. the optimum concentration is at the level of 75 mg / mL because at this concentration it has been able to inhibit the inhibitory zone value which is no different from 100 mg / mL.

Abstract

The fruit of Rhizophora mucronata Lamk content of tannin which can be used as natural dye color. Research purposes was to extract the fruit of R. mucronata, used the extract with fixation material as cotton natural dye, and evaluation the resistance of the color. The research was conducted for three months at Wood Technology laboratory and Wood workshop laboratory at Forestry Faculty Tanjungpura University. The fruit of R. mucronata was extraction with aquades with ratio 1:10 (weight/volume) at temperature ±80ºC for 60 minutes. The fixation materials were tawas, kapur tohor and tunjung. The cotton was dipped into the extract then analyzes the change of the color before and after the coloring process. After that the cotton was dipped into the fixation materials. The ratio of fixation materials and aquades was 1:20 (weight/volume). After coloring the change of the color was measured. Evaluation the resistance of the color after fixation was made refer on ASTM D 870-02-2002 for hot water treatment and ASTM D-1308-02-2013 for cold water treatment. The quality of color was measured with Munsell Soil Color Chart and Hunter Lab. The result of research showed that extract of R. mucronata give a pink color to the cotton with average value of ∆E was 22.74. The retention of extract to cotton was 4.47 g/cm3. The additional of fixation materials, i.e. tunjung and kapur tohor resulted the drak color meanwhile tawas made the lightest color. The average ∆E values were 6.16-39.84. Extract of fruit of R. mucronata with additional of tunjung as fixation materials can be used for natural dye for cotton and wood.

Abstract

Critical land is a damaged land, thus losing or decreasing its function to the specified or expected limits. The identification and critical lands mapping is essential for the planning and determination of priority watersheds in order to the utilization and development of natural resources and land rehabilitation and soil conservation. Remote sensing is a technique that enable people to collect data without direct field measurement. The using of Landsat 8 image then analyzed by using Geographic Information System (GIS) is being expected to improve the ability to classify land cover, the map was then overlad with parameter map based on Regulation of Director General of Management of Watershed and Social Forestry Number P. 4 / V-Set / 2013 about technical guidance on the preparation of spatial data of other critical lands to identify critical lands in Kayong Utara Regency.Keywords: Degraded land, Geographic Information System (GIS), Remote sensing, overlay

Abstract

People still use plants as a medicine to overcome a disease, because it is easily to obtain and relatively does not provide significant negative effects. One of the plants utilized by the people is Bellucia pentamera Naudin (B. pentamera). Diarrhea and typhoid fever are diseases that often assault Indonesian people. The bacterias were used in this study were Escherichia coli (E. coli) and Salmonella typhi (S. typhi). This study aimed to analyze the antibacterial effectiveness of B. pentamera bark extracts against E. coli and S. typhi, by Kirby-Bauer diffusion method with PCA as the media. The highest extract concentration against E. coli is 400 mg/ml possess an inhibition of 20±1 mm, and towards S. typhi is 80 mg/ml which possess an inhibition of 24.67±0,58 mm.Keywords: Bellucia pentamera, Disc Diffussion, Efectiveness, Escherichia coli, Salmonella typhi.
