Abstract

This is a quantitative research with experimental-type research with pre-experimental form of one graup pretest-posttest design. The research samples were 27 grade IIIB. Data Collection was carried out by observation, questionnaires, and documentation. Data were analyzed by using descriptive and inferential statistical analysis with SPSS version 20 computer program. The resuts indicated that the ability of teachers’ activities by applying poster-based ice breaking abtained an average of 3,4 meaning that it was carried out perfectly. The assessment of student activity in learning obtained average 3.3 with good category. The results of grade IIIB students learning interest were described by the inferential analysis results where the normality test was 0.205, the homogeneity test was 0.219 and the T test was 0.000, so the results indicated that therebis an effect of poster-based ice breaking on grade III students learning interest at Antang I Elementary School, Makassar. Therefore, through the analysis results, it can be concluded that poster-based ice breaking has proven to have an effect on grade III students learning interest of Antang I Elementary School, Makassar. Keywords: poster-based ice breaking, students learning interests

Abstract

Jarak pagar (Jatropha curcas L.) one as an antioxidant. This research aims to obtain a formulation in the form of a stable face mist dosage form and determine the IC50 value of the extra ethanol face mist preparation from jatropha leaves (Jatropha curcas L.) which has potential as an antioxidant. Experimental research method using 96% ethanol solvent, maceration method. The resulting thick extract is rotated, then preparations are made with concentrations of 0.1%, 0.3% and 0.5%, using additional ingredients glycerin as a humectant, propylene glycol as a humectant, sodium benzoate as a preservative, lavender as a fragrance and distilled water. as a solvent. Evaluation of the preparation, namely the cycling test in 6 cycles for 12 days, organoleptic observations obtained in liquid form, pH measurement results were <0.05p, homogeneity tests obtained homogeneous preparations, Viscosity test results were <0.05p, skin moisture and irritation tests were <0.05p. As well as antioxidant testing using the DPPH method using a UV-Vis spectrophotometer. The results of the research can be concluded that Jatropha curcas L. extract can be formulated as a face mist preparation that is physically and chemically stable. The IC50 values ​​using the facial mist preparation formula of Jatropha curcas (Jatropha curcas L.) leaf extract were respectively 17.0276 ppm, 16.5071 ppm, and 13.4743 ppm. The most effective face mist formulation has the highest antioxidant value in formula III.
