Abstract

Abstract: Research was aimed to improve study result of student on solubility and result times solubility subject has been doing in class XI science SMAN 1 Kampar. This research was a form of experiments research with design pretest-posttest. Sample of the research were student of class XI science 2 as experimental class and class XI science 3 as control class. The experimental class was applied learning model problem base learning while the control class using discussion method. Data were analized using t- test. Result from the data analysis showed t count > t table (1,6923 > 1,68). It means learning model problem based learning can increase study result of student on solubility and result times solubility subject in class XI science SMAN 1 Kampar with category of increase study results on the solubility and result times solubility in class XI science is high category.Key Word: study results, problem based learning, solubility and result time solubility

Abstract

ABSTRACTThe purpose of this study was to determine the self identity in terms of adolescent attachment to parents in SMKN 4 Yogyakarta. The number of samples used in this study amounted to 130 students of class X SMKN 4 Yogyakarta. The sampling technique used in this study was purposive sampling. The analysis of the data used in this study is the Pearson product moment correlation Results of this study indicate that there is a positive relationship between attachment to parents of adolescent self identity in SMKN 4 Yogyakarta. In a correlation test on adolescent attachment variables to adolescent self identity, there is a significant positive correlation. It can be seen from the coefficient of r = 0.599 with p = 0.000 (p <0,05). For variable self identity among young women and men there was no difference between the two. This can be seen with sig t 0.211 which means> 0.005. and independent simple t test.  Keywords: self identity, attachment to parents

Abstract

Guava leaf has various benefits, one of them is accelerating the healing process of a wound. This study aims to formulate the ethyl acetate fraction into a gel form and test the effectiveness of gel formulation toward open wounds in 16 male mices (Mus musculus) which made excision 1 cm circular full thickness wound on the back of mice parallel with Os. vetebra. The ethyl acetate fraction of guava leaf has been made into concentrations of 5% and 7% with base gel used as negative control and Bioplacenton as positive control. The evaluation towards ethyl acetate fraction gels showed the gels have green-yellow color, guava odor, homogenous, relevant pH to the skin 6,31-6,51, and spread over 2,8-3 cm (stiff gel). The gels were applied onto the wounds twice a day for about 21 days. The observation was conducted every day towards the scab formation day, scab chipped day, and wound healing day. The data were analyzed statistically using one way ANOVA then continued with Tukey test. The average day for scab formation, scab chipped, and wound healing process, successively are in the negative control i.e. 6,50 ; 13,50 ; 20,25, then positive control of  3,75 ; 11,00 ; 17,25, for gel with 5% concentration,  3,75 ; 9,75 ; 16,50, and gel with 7% concentration,  4,50 ; 12,00 ; 18,25. The statistical result showed that the ethyl acetats fraction  could accelerate the scab formation (p0,05) and the open-wound healing (p0,05) in mice than the control negative (p0,05), but not in the scab exfoliation (p0,05). Gel concentration 5% accelerated faster in forming the scab, flaking off the scab, and  healing the wound compared with the gel concentration of 7%.

Abstract

Abstract. Dental caries is a disease with a high prevalence of caries in Indonesia is caused by the bacterium Streptococcus mutans. The leaves of the soursop (Annona muricata Linn.) is one of the herbs that can remove dental plaque. This study aims to determine the chemical content and measure the inhibitory antibacterial soursop leaft methanol extractin inhibiting the growth of Streptococcus mutans bacteria. Phytochemical screening stated that the leaf of the soursop contains flavonoids, alkaloids, tannins, steroids, glycosides and saponins. Test of inhibition were measured using paper disc diffusion method with variation concentrations of 5, 10, 15 20, and 25%, positive control is tetrasilkin 30 µg, and a negative control is methanol. Antibacterial test results showed that the methanol extract of soursop leaves have antibacterial activity against Streptococcus mutans at concentrations of 5, 10, 15, 20 and 25% with inhibitory diameter of 9,1; 10,57; 11,53; 12,01 and 13,75 mm respectively. Keywords: Soursop leaves, Dental caries, Streptococcus mutans, Methanol.*Judul ini telah dipresentasikan pada Seminar Nasional: Indonesian Students Conference on Science and Mathematics (ISCSM) 11-12 November 2015, Banda Aceh Indonesia
