Abstract

Bivalve os one marine animals that can efficiently accumulate to heavy metal. This is due to they livein the base layer of the sediment in the aquatic and they are moving very slowly. Therefore, it has beendone a research about the analysis of consentration of lead (Pb) in the bivalve polymesoda erosa sp andthe bivalve anadara granosa at the aquatic of Salule Pasangkayu West Sulawesi has been reported byusing direct spectro. The research’s aim was to analyze concentration of Pb as heavy metal in the bivalvepolymesoda erosa and the anadara granosa sp, The results obtained that concentration of Pb at muddyplaces was higher than at sandy area. Level of Pb showed that Pb exceeds quality standard in both clamswhere in the blood clam was 3.75 mg/Kg and 3.857 in dry weight, while the Mangrove calm showedthe result of 5,00 mg/Kg and 5.25 mg/Kg in dry weight.

Abstract

This research was done due to known that most students got difficulty in learning and understanding chemistry material particularly on alkana, alkena and alkuna concept. This problem occured because there was still any teacher who use conventional method in delivering the material. To make the material easy to learn, not boring and easy to understand, the teacher needs to give a learning media. The objective of this research was to increase the students’ learning outcome on the material of alkana, alkena and alkuna in SMA Negeri 2 Dolo by applying Mollymood aid. The population of the research was the tenth grade students of SMA Negeri 2 Dolo in academic year 2012/2013 with sample was 26 students of Class XA as the experimental class (given Mollymood aid for learning)and 26 students of Class XB as the control one (given conventional method). The technique of data collection done through instrument such as achievement test of alkana, alkena and alkuna. The data analysis result obtained average score on experimental class was 23.35 with deviation standard was 2.66 whereas for control class the average obtained was 20.73 with deviation standard was 2.77. Hypothesis testing result obtained tcounted = 4.59 and ttable 1.67 with significant level (α) = 0.05. Based on the research result, it showed that there was a significant difference between students’ learning outcome on chemistry taught using molymood aid and conventional one of the tenth grade students of SMA Negeri 2 Dolo in academic year 2012/2013.

Abstract

Virgin coconut oil (VCO) can be made in several ways, namely through a heating process at low temperature, freeze-drying, fermentation, enzymatic, mechanical pressure or centrifugation. VCO with an enzymatic method is the making of VCO fromcoconut milk by using enzyme. The protein-oil bonds in the emulsions in coconut milk can be broken down into protease enzyme. The purpose of this research is to extract the protease enzyme in palado leaves and utilize the enzymes in the manufacturing process as well as determining the quality of VCO. This research method passed through some processes. Firstly enzyme extracts from palado leaves are prepared and coconut milk from coconut cream is made, then it is tested qualitatively the presence of protease enzyme with ninhydrin color reagent. Furthermore, the making of VCO enzymatically is undertaken by varying the ratio of the volume of coconut cream and enzyme extracts of 24 hours. VCO quality is analysis by using the parameters of smell, flavor, color, moisture content, levels of FFA (free fatty acid) and peroxide. The testing result with ninhydrin reagent gave a positive reaction (blue-purple) showing that there is enzymes alleged a class of protease in the palado leaf. The result of VCO made with the comparison of coconut cream and enzyme extracts from palado (10 : 1) has generate a VCO with a yield of 25.4%. However, from the analysis of VCO quality test results, it is obtained the smell of distinctive flavor oils, fragrance, the clean color, water content of 0.5% , FFA content of 0.25% and the peroxide number of 0 meq/kg.

Abstract

Moringa (moringa oleifera lamk) is a nutritious plant that can cure various diseases. Part of this plant such as leaves, roots, flowers, and fruits serve as a traditional medicine. The aim of this study is to determine the inhibitory of extract of moringa fruit on the growth of the fungus candida albicans. The extract of moringa fruit is made by using several solvents such as distilled water, ethanol and hexane. Suspension of the candida albicans obtained from Clinical Laboratory, Palu, Central Sulawesi. Suspension of the candida albicans is synchronized with Mc. Farland solution. The fungus test uses a pitting method. The results showed that inhibition of extract of moringa fruit on the growth of the fungus candida albicans with solvents of distilled water provides greater results as compared with ethanol and hexane. Based on the results of the observation, the percentage of inhibition of the extract of moringa fruit on the growth of the fungus candida albicans with various solvents are 100% for distilled water, 59.99% for ethanol and 6.97% for hexane. The result of phytochemical screening test showed that the moringa fruit contains alkaloids, flavonoids and steroids.

Abstract

Forest onion is a plant that is widely used as a traditional medicine and natural antioxidants. The aim of this study is to determine the extract of the forest onion that can inhibit the growth of the fungus candida albicans and to compare the inhibitory of extract of the forest onion (eleutherine palmifolia (L.) merr) by using different solvents, namely ethanol and distilled water which is carried out by the method of pitting. Suspension of the fungus candida albicanswas obtained from Clinical Laboratory Palu, Central Sulawesi. The results of research obtained that the inhibition of extract of the forest onion on growth of the fungus candida albicanswith ethanol was greater than with distilled water, the percentace was 65.44% and 54.78% for each solvents. It can be concluded that extract of the forest onion has the inhibitory on the growth of the fungus candida albicans.
