Abstract

There are about ± 4.000 wood species in Indonesia. In small amount of that woods were categorized as durable wood (Class I and II) while mostly (80-85%) were categorized non-durable wood (Class III to V). This study was aimed to determine the effects of Lantana camara L. leaves extracts as preservation material of Pterospermum sp wood on the Coptotermes sp. attacks. The experiment was conducted in the laboratory of Forestry science, Forestry Faculty, Tadulako University, from May to June 2013. The study was using completely randomized design with pattern. The treatment of study was applying two factors. First, concentration of L.camara L. extracts with three levels, namely ;9,09 g (K1), 13,04 g (K2), and 16,66 g (K3). Second, Dipping time with three levels, namely: 1 day (L1), 3 days (L3), and 5 days (L5). Data was analyzed by using analysis (Anova).The results showed that water contents and density of Pterospermum sp. woods was 8,37% and 0,321 g/cm³, respectively. Hence, the highest weight loss was achieved by K1L1 combination treatment (9,99%) while the lowest was achieved by K3L5 combination treatment (8,93%). Generally, concentration of L.camara L. and dipping time extracts did not affect significantly the weight loss of Pterospermum sp woods. Keywords: Concentration, Dipping, Lantana camara L., Pterospermum sp., Coptotermes sp.

Abstract

Wood has many contribution for life. It can be useful for bueldings, huose ware, and for other using. The use of wood are followed by huma needs for manufactured wood in creasingly, while long life wood tend to be more scarce and higher in price. This research aims to know the influence of the concentration and the immersion time for sengon wood treated in extracted soursop leaf to defence from subterranean termite. This research was conducted in both forestry Laboratorium, Departement and faculty of forestry, University of Tadulako and in rural of Baiya, Distict of Tawaely. Starting from Desember 2013 till Februari 2014. This research used a complete randomized factorial design. The first factor was the concentration of extracted soursop leaf (A) was 4.76% (A1), 13.04% (A2) and 16.66% (A3). The second factor was the immersion time for sengon wood treated in extracted soursop leaf (B) was 5 days (B1), 10 days (B2), and 15 days (B3). The results show that the highest of losing weight is in the control (A0B1) with 3.3%, and the lowest of losing weight is in the concentration of 150g with 10 days immersion (A1B2) with 1.21%. The concentration of extracted soursop leaf and the immertion time of sengon wood did not significantly influence to the lose of weight in tested sample. Keywords: Concentration, Dipping, Paraserianthes falcataria L. Nielsen, Annona muricata L , Coptotermes sp.

Abstract

The purpose of this study was to determine the resistant-termite activity through phytochemical analysis with color test methods and compounds from the extracts of ebony. The results of this study are expected to provide early information about the biological activity of extracts of ebony as a natural anti-termite and the possibility of its utilization as a natural preservative in wood preservation. Ebony (Diospyros celebica Bakh.) have a 1th durable class and 1th strong class. Ebony is the endemic species in Central Sulawesi. The methods of maceration ebony powder, extract ethanol, extraction and fractionation and phytochemical analysis through tests of alkoloid, flavonoid, terpenoid, tannin,  saponin, steroid, carotenoid and  cumarin were applied in this research.

Abstract

This study focuses on correlation between reading comprehension and writing ability in descriptive text. The researchers collect the data through two instruments, i.e. test of reading comprehension and descriptive text writing. This research is researched quantitatively and SPSS was used to analyse the data.  Then, the result of the study shows that mean score of reading comprehension is 72.47. It means that the students reading comprehension was good. Meanwhile, the mean score of writing ability in descriptive text is 61.14. In addition, the researchers found that r-counted is 0.098, and the r-table with n = 108 (df-2 = 106) with significance level = 95% (α = 0.05) is 0.189. It indicates low correlation between the two variables.

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

Accomplishing an assignment in academic writing course is not as easy as pie because there are many aspects that students need to follow to have an English writing with a good quality. Particularly, this study is aimed to investigate Foreign Language Anxiety (FLA) in academic writing specifically to EFL students at university level. The factors that cause the students feel anxious in English writing represent on close-ended questionnaires that the researcher asks the students to answer. In addition, the researcher does direct observation by acting as a passive observer where she has no role in conducting or helping the lecturer in teaching the writing course. In this case, what the researcher does is finding an appropriate spot in classroom in order to have a clear description regarding with ongoing process of teaching and learning of writing course of English Department students at Widya Gama Mahakam University, Samarinda, Indonesia. As a result, data analyzed by using Likert Scale indicate that High Anxiety (HA) appears to be the highest level in students’ anxiety with nine out of sixteen anxiety statements. In addition, Moderate Anxiety (MA) is also showed on the result with six out of sixteen anxiety statements. Furthermore, although Low Anxiety (LA) appears in only one out of sixteen statements, it is correlated to other facts i.e. the apprehension of working with English writing assignment under time constraint, lack of self-confidence because of inadequate capability in English language proficiency such as structural rules in English as well as an ability to relate and compare theories among experts to support their writing. Further implication for better research and lecture of English writing course in the future is also pointed out in this study.
