Abstract

The generation of ozone can be done by using high voltage so as to produce electronic discharge which will ionize the oxygen gas particles then recombination of these ions will produce ozone. The mosquito racket exploits a very high potential difference between its nets in order to burn the mosquitoes that trapped between the nets. The use of mosquito rackets in the air greatly enables the occurrence of electronic discharges that will produce ozone. In this study the mosquito racket is inserted in the sheath then activated for 60 minutes and ozone concentration is measured using ozonmeter every 5 minutes, the mosquito racket has an output voltage of 2500 volts and 5000 volts. On a 2500 volts mosquito racket the maximum ozone concentration of 1.70 ppm occurs at 35 minutes with an average rate of ozone production of 0.0133 ppm / min. On a 5000 volt mosquito rack a maximum ozone concentration of 11.40 ppm occurs at 35 minutes with an average rate of ozone production of 0.277 ppm / min. Keywords: Ozon, Electronic discharge, Mosquito racket.

The tools used in this study are questionnaires, interview guides, and documentation. After the data is collected then, the authors analyzed by using descriptive analysis. The results of this study indicate that parents are instrumental in generating learning motivation learners. This was conveyed by one of the children who stated "they are very interested if there are parents beside them while studying at home". Giving motivation is important for parents so that the child can learn well at home and at school, because parents are the motivator for the child in generating motivation to learn the child before the child is guided by the teacher at school. Keywords: Role of Parent, Learning Motivation

Abstract

The growth of bean plants can be enhached through the provision of fertilizer and organic material. The purpose of this research is to get the best concentration of Bayfolan leaf fertilizer and mung bean sprout (Vigna radiata L.)extract in improving the growth of green bean plants(Phaseolus vulgaris [L.] cv. Balitsa 2). This study was conducted using an experimental method in the greenhouse with a single factor Block Randomized design (BRD) consisting of 20 combinations of Bayfolan fertilizer and the extract of mung bean sprouts (V. radiata). Bayfolan fertilizer concentration used was 0, 2, 2.5, and 3 mL / L, while the concentration of bean sprout extract used was 0%, 20%, 40%, 60%, and 80%. The results of the Analysis of Variance (ANOVA) showed that the combination of 3 mL/L Bayfolan foliar fertilizer and 60% extract of mung bean sprouts was the best concentrations for the growth of green bean plants on plant height parameters, the number of leaves, the number of flowers, wide of leaf, and the weight of dried bush bean plants.

Abstract

The high number of tin mining in the Bangka Belitung Islands leaves a number of problems such as unused land after tin mining. Whereas on the other side, the post tin mining areas can be used as a source of water reserves although additional treatment is needed because it is feared contain heavy metals. Calcium oxide is a compound that can be used to coagulate dispersed pollutants in water so that it can be used to improve the quality of water stored in the post tin mining area. One of the most abundant sources of calcium in the Bangka Belitung Islands comes from wasted cockle shell. Through a heating process at temperatures of about 700°C calcium carbonate in the wasted cockle shell will begin to decompose into calcium oxide. Based on the results obtained have known that the longer the heating process then the decomposition process of calcium carbonate more and more occur. Keywords: Rietveld, calcium crystal, heat treatment.
