Abstract

High-grade durable wood could not be longer to meet the various needs, this caused by limited and the more expensive price, so it must use low grade durable wood. The use of low grade durable wood should be followed by the wood preservation process. This study aims to determine the preservative retention of leaves tembelekan (Lantana camara L) on bayur (Pterospermum sp), benuang (Octomeles sumatrana Miq) and durian (Durio zibethinzs) and its effectiveness against subterranean termites (Coptotermes sp), attack. It was conducted at the Laboratory of Agrotechnology, Faculty of Agriculture, University Tadulako in March to june 2014. Testing Subterranean termites (Coptotermes sp) test was carried out at the Maku Village, District of Dolo, Sigi Regency, Central Sulawesi, using a completely randomized design (CRD), with treatment of different wood species and 3 days soaking duration at a concentration of 1% preservative with 6 replications. The results show the moisture content of bayur, benuang and durian woods are 13,10%, 10,81% and 11,35% respectively. The wood densiy of bayur 0,480g/cm3, benuang 0,277 g/cm3 and durian 0,402g/cm3 and the highest retention values is found at wood of durian 59,09 g/cm3 and the highest retention values is at bayur 41,67 g/cm3. In addition, the highest weeight loss (leas effectiveness) of 15,02% on the wood of bayur (control) and the lowest (highest Effectiveness) on wood of benuang 0,72%.

Abstract

Effectiveness of natural substance as preservative agent is needed to be further observed. One of the substances is extract of Glove (Syzygium aromaticum) leaf. This extract was considered to be effective material on Durian (Durio zibethinus) wood preservative against Subterranean termite (Coptotermes sp). The aims of this study were compare the retention and the affectiveness of preservative materials which  extracted from Glove leaf by using different method of extraction. This studi was done at Agro-technology Laboratory of Agricultural Faculty, Tadulako University, over the period of March and June 2014. Bioassay on Termite destruction was done at Maku Village, Dolo of Sigi Regency. The experiment was arranged based on Completely Randomized Design (CRD) in two different factorial patterns. The first factor was different method on leaf extraction (A) i.e. by using ethanol (A1), and by using distillated water (A2). While the second factor (B) was different time on soaking material, i.e. 1 day soaking time (B1), and 3 days were soaking time (B2). All units was performed as negative control. One percent of preservative extract was applied on each experimental unit. The outcome of this study showed that water content of axtract was 14,726% and the density was 0,463 g/cm3. The highest retention value 0,1244 g/cm3 was recorded on the treatment of 3 days ethanol extraction (A1B2), while the lowest value 0,0868 g/cm3 was detected on the treatment of 1 day water extraction. The highest value on effectiveness (or lowest rate on loss weight) 2,4075% was detected after the treatment by using 3 days ethanol extraction substance, while the lowest value 4,6818% was  measured on control unit. Key words: Syzygium aromaticum, Durio zibethinus, Retention, Effectiveness.

Abstract

Many favorable properties of wood are available in almost all parts of the world, easily obtained in different shapes and sizes, relatively easy to process, as well as very decorative appearance. However, wood also has a weakness that could be damaged by a variety of factors either biological, physical, mechanical or chemical. In reality, the main factors causing damage to the wood are fungi, bacteria, insects and marine animals (marine borer). The organisms might damage the wood because they make as a shelter or as feed. Therefore, there should be conducted wood preservation to overcome the unfavorable properties of the woods. Wood preservation aims to extend the use of low-class durability of timber species such as Bayur (Pterospermum sp), Durian (Durio zibethinus) and Benuang (Octomeles sumatrana Miq). This study aimed at determining the effectiveness of a natural preservative tembelekan (Lantana camara L). The research was conducted at the Forestry Sciences Laboratory, Department of Forestry, Forestry Faculty, Tadulako University and Talise Mantikulore Sub-district, started from May to July 2013. The study was designed with the method of completely randomized design (CRD) with three wood species treatment, namely bayur, durian and benuang. Each was preserved with a natural preservatives of tembelekan extract with a concentraation of 13,04%. There were 10 samples of each type of wood, consisting of 5 test samples preserved and 5 controls (without preserrvatives). There were 30 test samples. The parameters observed were preservative effectiveness of the sample weight after feeding on soil termites. The study shows that highest natural preservative effectiveness on benuang wood was preserved with the sample weight loss of 2,25% and the lowest on bayur wood was preserved with the sample weight loss of 3,47% when they were compared with the control sample (without preservative). Using tembelekan extract might increase wood resistance to soil termite attacks. Keywords: Captotermes sp, Durio zibethinus, Lantana camara L, Octomeles sumatrana Miq, tembelekan.

Abstract

Study of diversity and abundance of social bees (Apidae) in the pesticide-applied seasonal crops were carried out for nine species of crops in a lowland area, Dramaga, Bogor and on 17 species of crops ina highland area, Lembang, Bandung, both in the province of West Java. Two species of honey bees (Apis cerana and A. dorsata) and one species of stingless bee (Trigonalaeviceps) were recorded from the lowland crops,while only A. cerana was found in the highland crops. The most abundant bee species on both low and highland was the honey bee A. cerana. The number of A. cerananests and T. laevicepsnests in the surroundings of the study sites were relatively high. Colony members of both bee species were very active to collect nectar and pollen from flowers in non-pesticide-applied sites; however, the density of bees visiting flowers in pesticide-applied seasonal crops in both lowland and highland were relatively low.

Abstract

The role of the wild plants in relation to the conservation of the Indonesian insectpollinators was studied at several areas of Java. Three of direct observationmethods were applied: study of biodiversity and observation on the wild flowersand the insect pollinators as well, and the behaviour of the insects. The flowersof wild plants were relatively smaller and paler in colour, however they were moreattractive to insect pollinators than cultivated plants. Flowering time of the wildplants was mostly during wet seasons, contrary to that of the cultivated plantswhich was mostly during dry seasons. Our observation indicated that these wildplants are the food resources of insect pollinators during wet seasons. Observationdata support the importance of wild plants to supply food to insect pollinatorsduring wet seasons. Management of wild and cultivated plant environments isnecessary to conserve insect pollinators.

ABSTRACTDistribution Pattern of Butterflies on Various Ecosystem at Mt. Ciremai. To know the effectof ecosystem type on distribution pattern of butterflies in Ciremai mountain, we comparedbutterfly fauna between urban area (perkampungan), secondary and primary forest from 1000m asl to 1700 m asl., located in Apuy and Linggarjati tracks. During our study in Apuy (4 ? 22April 2006) and Linggarjati (15 May? 4 June 2007) we recognized 66 species within 7 groups.Four groups distributed in specific habitats such as (1) perkampungan (Argomukti vilage,Apuy, 1000-1200 m.asl.), (2) secondary forest (Legok Pasang, Apuy, 1500-1600 m.asl.), (3)outsite forest Linggarjati, 800-1100 m.asl. (4) Linggarjati forest edge at 1100-1400 m asl. Theothers groups are butterflies that only distributed in Linggarjati or Apuy. Microclimate duringour study as well as weather condition at the time such as cloud, wind and rain impact theactivity of butterfly species and reflected to the species collected. Although the researchconducted in the same season (wet season) but Apuy and Linggarjati have differentmicrohabitats that caused some species are only found at Apuy or Linggarjati areas.Key words: Ciremai, butterfly, distribution
