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

This research was conducted to determine the level of a dye, rhodamin B, and a preservative, benzoic acid, on tomato sauce distributed in the area of Palu city. The food additive is used in order to get more interesting color and the benzoic acid is used to keep the food fresh for a long period of time. The research method used was a thin layer chromatography. It was aimed at knowing weather there was a dye called rhodamin B in the research sample or not. From the analysis result, it can be said that the sample did not contain the dye rhodamin B. in addition, another research method used was alkali acid titration which was used to examine the sample quantitatively and qualitatively. From the qualitative examination, it was found that all tomato sauced sampled positively contained the preservative benzoic acid. The tomato sauce produced by Mojokerto-Indonesia contained 34.7mg/kg while the one produced by Urabaya-Indonesia contained 40mg/kg. In conclusion, (1) all sample of tomato sauce examined did not contain Rhodamin B,the red dye substance, which was forbidden to be used for food, cosmetics, and medicine according to the Health Ministerial Regulation of Indonesian Republic No. 722/Menkes/Per/IX/1988 concerning food composition; and (2) the content level of Benzoic Acid in tomato sauce spread out in the traditional market, Inpres, Palu city has fulfilled the standard, i.e. + 1000 mg/kg. However, it is expected that all people must still be careful when buying and using tomato sauce.

Abstract

Stale rice is the production result of inapproprite food to consume due to have bad smell and taste, mucus appearance, grown with yellow or orange fungus and sour taste because microorganism living in it. It is only throw by the household as the waste. Thus, it needs a process that it becomes useful and quality product. One of the product is the making of liquid organic fertilizer (POC). This study aims to create a POC and determine the amount of nitrogen in the POC. The research method is the preparation of stale rice, followed manufacture of POC through fermentation and determination of N-Total with destruction. POC later applied for fertilization in plants of orange paper flower (bougainvillea spectabilis), then performed observations shoot height of plants , leaves number, leaves shape, leaves colour , flowers number and the analysis of one of ingredients N-total POC in stale rice. N-total in POC of stale rice obtained wet destruction method as much as 92 mg/L (92 ppm). The liquid organic fertilizer from stale rice can accelerate the growth of orange paper flowers (Bougainvillea spectabilis) is indicated by the number of shoots, leaves and flower petals.
