Abstract

In this work, cockle (Clinocardium nuttalli) shell waste is massively produced by many restorant in Banda Aceh Indonesia. The cockle (Clinocardium nuttalli) shell is known high calcium; therefore it is potential to be used as calcium source of catalyst for transesterification reaction. The aim of thisresearch is to study the synthesis and characterization of Clinocardium nuttalli shell. Clinocardium nuttalli shell was prepared by calcinating the shell at 500 and 800°C. Synthesis of solid catalys was employed for transesterification reaction of calophyllum inophyllum L. oil. The reaction was carried out in batch reactor at temperature of 65oC and ratio of mrthanol:oil of 3:1 - 12:1. The synthesized samples were characterized by X-ray diffraction (XRD). Analysis data by XRD confirmed that the obtained crystal calcined at 500 oC areCaCO3 calcite, CaCO3 veterite, and CaO. XRD patterns of the colcined shell at 800 oC shows sharp peaks of crystalline phase of CaO. The best characteristics is obtained at calcined catalyst of 800oC with molar ratios of methanol:oil of 12:1, i.e. density 0.832 g/cm3, viscosity 4.92 cst, and yield 84.1%.

Abstract

 Abstract. Advanced statistical codes we present in MINITAB statistical environment, produces comprehensive computational and graphical outputs for the best stability analysis, additive main and multiplicative interaction effect (AMMI). The experiment comprised of a population of doubled-haploid wheat lines at 2006-2009 ys. As lattice designs. The results of AMMI analysis of grain yield showed the significant (P0.01) effect of years, lines, and their interaction effect, along with 49.1, 7.80 20.63% of the total variation, respectively. Also the written macro partitioned the GEI effect to three IPCA scores, accounted for 40.70, 35.32 23.96% of the GEI, respectively. The results of the cross-validation with FR (Cornelius) indicated the appropriateness of AMMI2 model, whereby the biplots of genotypes years drawn, by which the stable genotypes were chosen. This program provided useful computations such as: principal component analysis, cluster analysis, Finlay-Wilkinson stability regression analysis and so on. In general, this program has a high potential for AMMI yield (etc) stability analyses, following estimating their parameters and could be applied by researchers working with stability analysis in plant breeding programs to obtain the most tolerant/resistant cultivars during multienvironment trials.

Abstract

Urtica dioica (Stinging nettle) leaves have been used as a traditional medicine to treatrheumatoid arthritis, to alleviate rheumatic pain benign prostatic hyperplasia (BPH), diuretic and prevention of kidney stones by local people in Middle East region especially in Iran, Turkey and East Europe. Hence, this investigation evaluates the antidepressant effect of selected crude extracts in the forced swimming test (FST) and tail suspension test (TST), two models predictive of antidepressant activity. The acute treatment of mice with extracts by intra-peritoneal (i.p.) route significantly reduced the immobility time in the FST (50 and 100 mg/kg) and TST (50 and 100 mg/kg), as compared to positive controls (haloperidol and fluoxetine) at 1 and 10 mg/kg, respectively. On the third day of experiment, a significant decrease of mobility was observed for chloroform extract (CE I) and butanol extract (BE II) compared to first day. CE I and BE II led to reduction of immobility time, as the selected extracts with two doses administered were different compared to the control, in the FST method by 65.37% and53.92% for 100 mg/kg, respectively. However, CE I showed the best result compared to our positive controls. Similar results of increased antidepressant effect, that was, of immobility time depending on the concentration administered, were obtained with the TST method. Also our data showed that there was no significant differences between doses (50 and 100 mg/kg). The results suggested that the antidepressant action of the butanol extract and of U. dioica its fraction (BE II2) was mediated by an interaction with 5-hydroxytrptamine (5-HT). U. dioica showed a potential source for the isolation of important natural products with antidepressant-like properties. However, further studies are still required

Abstract

The research was conducted to determine the effect of Tiens Golden Harvest (TGH) fertilizer concentration and the varieties on growth and yield of Roselle, and also to examine the interaction between the two factors. The research was conducted in the Experimental field of Agriculture Faculty, Syiah Kuala University, Darussalam Banda Aceh, from June 2010 to November 2010. The material used was Roselle seed varieties, manure, TGH, using Factorial Randomized Block Design 4 x 2 in three replications. The first factor used was TGH fertilizer concentration (i.e. 0;5;10;15 ml/l) and the second factor was Roselle varieties (Sabdariffa and Altissima). So, we were conducted 8 combinations of treatments which were designed into 24 units of experiments. The concentration of TGH fertilizer significantly effect on plant height on 15 and 30 days after planting (DAP), the diameter of the base plant’s stem on 15 DAP, the number of calyx per plant and the weight of calyx without seeds per plant for 5 times harvest. The best growth and yield of Roselle plant result was found in using TGH 10 ml/l of water. After 5 times harvest, using 10 ml/l TGH we got 54.93 calyx/plant with 43.33 dry weights. Variety significantly effect on the plant length on 15 and 50 DAP, the diameter of the stem on 15 and 50 DAP, and Roselle calyx fresh weight for 5 times harvest. The growth and yield of Altissima variety on this experiment was better than Sabdariffa variety. For 5 times harvest of Altissima variety, the number of calyces per plant was 46.47, the fresh weight was 457.60 g and dry weight was 39.09 g. There was a significant interaction between TGH fertilizer concentration and Roselle varieties on the stem diameter 50 DAP and the fresh weight of calyx. The best growth and yield of Roselle showed on the application of 10 ml/l TGH fertilizer to Altissima variety, with total fresh weight calyx was 457 g.

Abstract

The fruits (figs) of fig trees (Ficus spp, known as ‘bak ara’ in Aceh), are the source of food for many species of faunas in the forest, including birds, monkeys, orangutans, etc.  Pollination within the figs totally depends on female fig wasps that belong to family Agaonidae. Fig trees and their pollinating wasps rely on each other to survive.  Female fig wasps are known to transport nematodes into receptive figs when the wasps enter the figs to lay  eggs.  An investigation on the nematodes carried by female pollinating wasps Ceratosolen fusciceps Mayr into figs of Ficus racemosa was conducted in Sumatra, Indonesia. The figs on the trees were regularly sampled to determine the presence of nematodes and infer their ecology. The Baermann funnel method was employed to extract the nematodes from the figs.  Eight species of nematodes were recorded from the figs, two of which are still unidentified.  The species found were (1) Teratodiplogaster fignewmani, (2) Teratodiplogaster sp., (3) Parasitodiplogaster sp., (4) Schistonchus sp1., (5) Schistonchus sp2., (6) Mononchoides sp., (7) and (8) two undescribed Diplogastridae species (‘umbrella-like’ species 1 and species 2).  This is the most diverse fig nematode community recorded. The highest nematode populations were routinely found in D-phase figs, when the new generations of wasps were about to emerge.   Details of the ecology of each nematode species are likely to differ, but as a group they did not seem to significantly affect seed and wasp development in F. racemosa figs

Abstract

Few road traffic studies were conducted in Jordan, but the issue is drawing an increasing attention due to its growing magnitude and various impacts as a result of the high increase in vehicular traffic. This study further investigates the issue with the aim of providing an understanding of its social impact on residents of Amman, the capital of Jordan. Traffic noise levels were measured at selected locations along urban arterials and a social survey was performed to examine the reactions and attitudes of the neighboring residents towards these levels of traffic noise. The survey included social characteristics of individuals, and their attitudes towards traffic noise, and how it impacted their daily activities. A predesigned questionnaire was used for this purpose which included questions to evaluate the awareness of respondents of the problem and its environmental and health impacts. The financial impact that residents perceive of noise and the need for attenuation measures were also addressed. The results of the study also revealed that the impact of traffic noise on people can cause annoyance while performing daily activities were 24% of respondents reported that they get annoyed by traffic while working, 49% while resting, 34% while talking to others, 31% while talking on the phone, 39% while reading, 38% while watching TV and 53% of respondents get annoyed while sleeping. The respondents have also pointed out the following effects of noise: twist in mood (53%), headache (36%), and difficulty in concentration (40%). About 57% of respondents think traffic noise reduces the value of their properties and a total of 31% are willing to sell their house at reduced cost. About 59% of respondents consider attenuation measures necessary, and in order to reduce the noise, about 54% of respondents were willing to pay for attenuation measures which reflects the public awareness of the issue magnitude. Keywords: traffic noise, noise level, survey, social impacts.

Abstract

After affected by the giant tsunami waves following the 9.1 earthquake on December 26, 2004 in Aceh province of Indonesia, many of natural resources were damaged, including the loss of germplasm of rice in low land area. Therefore, we attempt to collect and evaluate the Acehnese germplasm of rice. We identified the Acehnese accession of rice by describing the characteristics of the rice plant using cultivation method of system for rice intensification or SRI with organic approach. Some of the descriptors include days of tillage formation, days from emergence to flowering, kernel weight, plant height, and yield components. We found that the Acehnese rice germplasm collection is very diverse: the days of tillage formation is 6 to 18 days after planting; the days from emergence to flowering is 56 to 90 days, plant height is 77 to 121 cm,  and 1,000 kernel weight is 19.47 to 30.27 g. So, we concluded that the diversity of Acehnese rice is very rich, the rice accessions were identified and now stored in the cool storage system. Evaluation of the accession showed considerable promise as material research with high yield potential, high levels of tolerance to stresses such as weeds, drought, acidity and blast for further evaluation. The progenies might provide the improved sustainability of intensified systems through durable crop resistance to biotic and abiotic stress. In the future, characterization traits will be selected for resistance to pests-diseases, and tolerance to drought and salinity stresses, as well as analysis of grain quality. We will also develop the high multiple resistance to environmental stresses.
