Abstract

Kaffir lime leaves (Citrus hystrix DC) has the potential to be used as a natural preservative especially an anti-termites. The study aims to evaluation the toxicity of extract of leaves C. hystrix against subterranean termites Coptotermes curvignathus Holmgren and to determine the optimal concentration of extract lime leaves on subterranean termite activity. Lime leaves were extracted using maceration method with methanol. Level of concentration were 0%, 2%, 4%, 6%, 8% and 10%. Filter paper soaked at each concentration thengive as a food source to subterranean termites. Bioassay tests were carried out for 21 days. Then mortality and filter paper weight loss was measured. The results showed the concentration level of 10% has the highest termite mortality with average value of 100% and has the lowest value of filter paper weight loss with a average value 13.48%. However, the optimal concentration was achieved at 8% due to the mortality rate reached 94% and the level of termite activity was classified as very strong.

Abstract

The study aimsto evaluated the activity of salam leaf (Syzygium polyanthum Walp) against subterranean termite (Coptotermes curvignathus Holmgren) and found the best level to inhibit the termite attack. Salam leaf was cut into small pieces, macerated with methanol for 24 hours, and evaporated with rotary evaporator. The essential oils were put into whatman paper with dosage level 0 ml; 0.1 ml;0.2 ml; 0.3 ml; 0.4 ml respectively. Then the paper put into medium of bioassay to termites for 3 days. The result of showet that dosage level 0.4 ml made 100% termites mortality with paper weight loss 0.42%. The higher dosage level resulted the higher mortality of termites. The optimal level of essential oils to inhibited the subterranean termites Coptotermes curvignathus Holmgren attack was achieved on level 0.3 ml. Keywords: Antitermites activity,Coptotermes curvignathus Holmgren, Essential oils, Syzygium polyanthum Walp.

Abstract

The research aims to determine the physical properties (moisture content, density and dimensional stability) and mechanical properties (modulus of elasticity, modulus of rupture, and modulus of crush stiffness) of Elaeis guineensis Jacq based on the position the trunk). The design used in the study was a completely randomized design (CRD) with 3 replications and the factor is the position of the stem height (low, middle, and top) of oil palm (Elaeis guineesis Jacq). The results showed that height position have significant value to moisture content, MOR and MCS, but did not significantly affect the value of density, dimensional stability and MOE. The moisture content value was range from 38,49 % - 101,07 %, and the density value was range from 0,46 gr/cm3 – 0,62 gr/cm3, meanwhile the dimensional stability value was range from 11,54 % - 19,84 %. The modulus of elasticity value was range from 4456,77 gr/cm2 – 10062,40 gr/cm2, and modulus of rupture value was range from 108,20 gr/cm2 – 354,47 gr/cm2, meanwhile the modulus of crush stiffness value was range from 16,56 gr/cm2 – 69,96 gr/cm2. The research concluded that oil palm trunk in the low position have physical and mechanical properties better than in the middle and top, and enroll in class V of strongness and suitable for use as raw material for particle board or other composite products.

Abstract

The study was conducted in serambai village, Sub-District of kembayan, Sanggau. The purpose of this study is to determine the types of plants, particularly certain parts of plants that can be used for treatment of various diseases and to know the way of processing by Malay and Dayak communities in Serambai village. The results of this study are expected to provide information to society about the benefits of some medicinal plant species that exist in the village of Serambai and invite surrounding people to preserve and cultivate such medicinal plants for the benefit of general public in future. Based on the results of research on some medicinal plants used by the Malays and Dayaks in surrounding village of Serambai, there are 51 species of medicinal plants that belong to 35 families. Surrounding communities usually cultivate such medicinal plants traditionally based on habits and experiences. Based on the growth rate, the percentage of trees that were used by people in Serambai village amounted to 33,33% while based on the type of single herba, 78,43% was benefited. Leaves were part of plant that often usedby villagers. Its amount was 39,62%. For processing, boiling is a favorite pattern that was often applied by people with percentage amount of 58,50%. Having processed traditionally, 59,26% of people taking it by mouth and 72,22% of local people exploited the properties of the leaves to treat internal illnesses.
