Abstract

Study for local knowledge about ethnopharmacology especially medicinal plants used by the community is still limited. West Kalimantan possess a tropical rain forest with megabiodiversity. One of the areas where Malay and Dayak people use medicinal plants from the forest is Sekabuk village, Sadaniang Subdistrict, Mempawah District of West Kalimantan,  Indonesia. This research has two objectives: first, to summarize the local knowledge of medicinal plants in the Sekabuk village, and second to identify the the mechanisms of shared on knowledge on used the medicinal plants on each ethnic. The research was conducted by in-depth interview and survey for 45 days in the village. The research programme consisted of interviews, plant observations, and a collection of medicinal plants from five different subdistricts sites i.e. Gelombang, Malangga, Pak Nungkat, Sekabuk, and Titi Dahan. The whole plants, part(s) used, and remedy formulations were elicited from healers and voucher specimens were collected for identification and stored at Forestry Faculty, Tanjungpura University. The results showed that there are 66 plants used for medicine. The family of plants consisted of Zingiberaceae, Lamiaceae abd Mrytaceae. The leaves  were most frequently used (108), followed by roots (47), whole plant (21), top (6), stems and fruits (5), and sap (1). The methods for preparation and administration and the awareness of medicinal plants are different by ethnic groups and the living environments. The difference between the genders did not significant in terms of knowledge about medicinal plants. Meanwhile, A retention of traditional knowledge of medicinal plants was significant in rural of West Kalimantan. The plants used as medicine were clearly different by ethnic groups, Malay and Dayak. The living environments also affect the difference of used plants on basis of plants accesibility.

Abstract

Wood anatomy of 417 genera and 86 families belong to the major, minor, and the lesser  known timbers of South- East Asia have been studied and described in 3 volumes of PROSEA books. This paper deals with timber species  of the least known timbers, which have  not been  treated in the above  mentioned  PROSEA books, i.e.:  Saurauia bracteosa, S. capitulata., and S. nudiflora from family Actinidiaceae.  The  objective  of this study was  to acquire  descriptions of their anatomical  features and evaluate  the quality of their fibres for pulp and paper manufacture. Samples were provided by Xylarium Bogoriense,   which were collected  from various  forest  areas   in  Indonesia.   Microscopic features  observed comprise all features those listed by IAWA Committee in 1989. Fibre quality was determined based  on their dimension and evaluated  according to quality classification developed  by FPRDC  Bogor. The results indicate  that identification of timber up to genera level is possible. Fibres of Saurauia spp.  fall into quality class  I, which  means   good  for pulp and paper. The descriptions of anatomical features were presented. Sauraria have  bright color, light yellow to light brown, fine texture, light, smooth to rather rough surface,  and make it suitable to substitute ramin (Gonystylus  spp.)

Abstract

West Kalimantan wooden craft is internationally well known and its export is increasing. Currently, high durability and attractive color of wood material such as belian (Eusideroxylon zwageri Teysm & Binnend) is rarely available, then alternatively mangium (Acacia mangium Willd.) and laban wood (Vitex pubescens Vahl.) are used for handicraft. Fumigation is one possible way to improve wood service life and color shades. This paper determines the impact of traditional fumigation on wood raw material on physical, mechanical and anatomical properties. The timber fumigation technique was conducted for one week, with curing time from early morning until late afternoon. After treatment, the physical, mechanical and anatomical properties of wood were evaluated. The different of color before and after treatment was measured by image processing scanner Canon P 145. Physical and mechanical properties refer to the British standard method. Result shows that fumigation improves the quality of wood, especially on color of wood. The wood became dark and more shining. It’s good for the handicraft materials. The quality of wood on moisture content value, both on mangium and laban wood was increased with average 30-50%. The average value of wood density of mangium wood after treatment with fumigation was 0.52, meanwhile laban wood was 0.55. The average value of radial shrinkage of mangium wood after fumigation treatment was 3.96% and tangential shrinkage was 6.34%. The average value of radial shrinkage of laban wood after fumigation was 6.43% and tangential shrinkage was 6.08%. The average value of hardness of mangium wood after fumigation treatment was 470.13 kg/cm2  and laban wood was 625.46 kg/cm2. The Fumigated  wood color was darker and more attractive for decorative and  craft products than non-fumigated wood. In general, this method could be used to preserve wood and to increase the physical performance of wood as raw material for handicraft.

Abstract

The aim of this study was to investigate the effect of gum rosin impregnation upon a low quality young teak wood in order to enhance its quality. The main objective of the treatment was to enhance the dimensional stability, as well as strength and to reduce the hygroscopicity. A 15-years old thinned teak wood (Tectona grandis L.f.) and gum rosin from Pinus merkusii Jungh. et de Vries were used for wood modification treatment by impregnation. Three kinds of non-polar solvents, i.e. turpentine oil, petroleum oil and n-hexane-, were used to make gum rosin solution. The results indicated that gum rosin impregnation did not markedly enhance the quality of young teak wood in terms of either dimensional stability or hygroscopicity; however, a little enhancement was delivered by using 15% gum rosin solution with n-hexane as the solvent. The treatment with petroleum oil solvent (at concentration of 7.5%) and at 15% concentration with n-hexane solvent resulted in highest bending properties. The highest bonding strength in dry condition was resulted by treatment with turpentine oil solvent.

Abstract

Paper industries commonly produce pulp sourced from a mixture of pulps, rather than from a single pulp, to obtain desired properties. In addition, the beating process is an essential step with respect to physical properties of pulp. Kraft pine (Pinus merkusii/PM) pulps were beaten to different degrees, i.e 200~300 CSF (heavy-beating) and 300~400 CSF (moderatebeating), paper sheets then were formed from each beaten sample. It was found that the strength properties of prepared paper sheets decreased the longer they were beaten, particularly as seen by the tear index and fold number. By microscopic investigation, it was found that cut or shortened fibers occurred very frequently in the pine pulps. Furthermore, the effects of heavily beaten pine pulp additions on handsheet properties of kraft pulps of Acacia nilotica (AN) were investigated. Four different mixing ratios by weight of AN/PM from 100:0, 90:10, 80:20, and 70:30 during beating, as well as four different kappa numbers of AN pulps (32.5, 34.0, 34.2, and 35.9) were applied. In general, the decrease in strength properties (3~25%) that occurred with increasing pine pulp ratio was more evident between pulp without pine and a 30% ratio of pine pulps. Fold number was reduced considerably (2.8~24.7%) by the blend composition but less pronounced in tear index (3.0~8.9%) from the initial values. However, the 10% or 20% ratio of PM pulps could increase opacity, brightness, and strength properties in some cases. No clear trend was found with increasing kappa number.
