<![CDATA[This study aims to determine the effect of PBL (Problem based Learning) model on motivation and learning outcomes of students grade VII SMP Negeri 5 Pallangga Gowa District. This type of research is quasi experiment with Pretest-posttest nonequivalent control group design. The population of the research is the students of SMP Negeri 5 Pallangga consisting of seven classes with the number of students as much as 203 peoples. The sample was chosen by double random sampling technique,Ramlawati (2017)2one experiment class and one control class. Data collection using questionnaire instrument to measure learning motivation and learning outcomes instrument to measure students learning outcomes. The data were analyzed by descriptive and inferential statistics. The average score of motivation after learning was 105.6 (high category) and average score of learning result was 87.17 (very high category). The result of inferential analysis by using t-test of learning motivation was obtained tcount 1.89 and result of t-testresult of study tcount 4,57. Both results indicate that t-calc> t-table(t-table1.67). This means that H0is rejected and H1is accepted. It can be concluded that there is an influence of PBL model on learning motivation and learning outcomes of science students grade VII SMP Negeri 5 Pallangga Gowa District on the subject matter of Environmental Pollution.]]>

<![CDATA[Java wood (Lannea coromendelica) is a plant that is spread in various regions and has the potential to be explored in its use. This study aims to explore Java Wood (Lanneacoromendelica) by determining the type of solvent and the best method of extraction in extracting the content of secondary metabolites of Java Wood clica (Lanneacoromendelica). Extraction was carried out by maceration method using ethylacetate and ethanol 70% solvent and using dry and wet samples, so that four kinds of extracts were obtained, namely 70% ethanol extract of wet Java wood clica (KJBE70%), 70% ethanol extract of dry Java wood clica (KJKE70%), dry Java woodclicaethyl acetate extract (KJKEA), and wet Java wood clica extract (KJBEA) The secondary metabolite compounds found in Javanese wood (Lannea coromendelica) are flavonoids, saponins, tannins, and terpenoids. Wet Java wood clica extract (KJBEA) has the highest secondary metabolite compound content of three compounds namely flavonoids, saponins, and tannins.]]>

<![CDATA[The ability to think creatively is one kind of higher order thinking. Wasis et al. (2014) stated that the ability to think critically is not only necessary inthe learning process but also necessary for applications in everyday life. Therefore, the ability to think creatively as part of higher order thinking necessary to serve as one of the important objectives to be achieved for education today. In an effort to develop creative thinking abilities of students, the necessary aspects that can serve as the basis development creative thinking abilities of students, one of the aspects that can be assessed is the ability of self-regulation. This study aims to determine whether there is a relationship between self-regulation with creative thinking ability of students of grade XI in Takalar. The study sample consisted of 134 studentswho were selected using purposive random sampling technique strativied. Data were collected by using self-regulation questionnaire consists of 40 items (α = 0.756) and creative thinking abilities questionnaire consisting of 32 items (α = 0.825). By using simple correlation and regression analysis, found that the correlation coefficient between these two variables is 0.595, p = 0.000 (p <0.05). This value indicates that there is a relationship between self-regulation with creative thinking ability in chemistry and the relationship between the two variables is a positive relationship.]]>

<![CDATA[The purpose of this study was to determine the effect of the Discovery Learning learning model by utilizing the environment as a learning resource on the motivation and learning outcomes of seventh grade students at MTs Pesantren Al Qamar Kab. Takalar. This type of research is a quasi-experimental research (quasi-experimental). The research sample was selected using a purposive sampling technique as many as 2 classes with 20 students in each class. Data analysis used covariance analysis test. The data obtained were analyzed descriptively and inferential analysis using the computer application SPSS version 20.0 for windows. The results of the analysis of the anacova test on the intercept value showed a constant value with a significance of 0.000 <0.05, meaning that the pretest and the learning model using the environment simultaneously had different impacts on motivation and learning outcomes. The significance value of the initial ability (pretest) shows 0.235 > 0.05, meaning that the initial ability is not significant on learning motivation with the impact of treatment at 3.8 percent and 0.029 <0.05, meaning that the initial ability has a significant impact on learning outcomes 12.3 percent. The learning model shows a significance value of 0.006 <0.05 on learning motivation and 0.029 <0.05 on learning outcomes, meaning that learning models using different learning resources in each research sample have significant differences on student motivation and learning outcomes with the impact of each treatment. -each variable is 19.0 percent and 12.3 percent.]]>

<![CDATA[Subdistrict Galesong is lying areas and coastal areas with an altitude of 0-100 meters above sea level. This spurred the use of land for the functional area awakened. Based on this case, it is necessary to conduct research on seismic vulnerability distribution in Kecamatan Galesong of Takalar Regency. Primary data are taken directly around the north coast Galesong using 303S TDL. The data taken as much as 5 points of measurement with the distance of each point about 500 meters. Further data measurement is then processed with Geopsy software. The frequency value is 0,416-0,509 Hz hence the dominant alluvial rock study location, where at point MG02 is the most vulnerable area with value 105,9918. While based on the value of PGA is 8.4-9.4 Gal, then the location of research including very small level of risk of earthquake.]]>

<![CDATA[This research was a classroom action research that aims to find the steps of applying the learning cycle 5E model which was integrated with the problem solving method so that improve learning activities and problem solving abilities of the students ontitration material and the solution equilibrium. This research took place in two cycles, each consists four stages, namely planning, implementing actions, observing, and evaluating. Data collection was performed by using observation sheets and problem solving ability tests at the end of each cycle. The data obtained were analyzed descriptively by describing a general description of the data during the study. The results showed the activity and problem solving ability of students increased after applying the learning cycle 5E model with steps of the engagement phase, exploration phase, explanation phase, elaboration phase which was integrated with the problem solving method, and evaluation phase. The results showed the average of students’ learning activities increased from 72.0% in the first cycle to 76.3% in the second cycle, while the average of students' problem solving abilities increased from 78.3% in the first cycle to 84.8% in the next cycle.]]>
