Learning science in Junior High School in Pidie district has not yet developed the ability to think scientifically. Leanears have not been able to do a problem analisis and argue with the evisidence and experience of the investigation. That are not given the opportunity to have learning activities that could improve their thinking, and then the equipment used in the process of teaching and learning on the concept of plants and animals reproduction are inediquate. It is proved by the laboratory space that has not been used and incompleted equipment. This study aims to determine the differences in the implementation of integrated STEM learning and STEM Silo on the ability to think scientifically on plant and animal reproduction concept in class IX Pidie State Junior High School. The approach used in this study was quantitative, the type of research was applied research; the method used is quasi-experimental, with the Nonrandomized control group pretest-posttest design. The population in this study amounted to 236 students and the sample to 75 students. The research procedure consisted of giving pretest, giving STEM integrated treatment in the experimental class and STEM silo in the control class, and giving posttest. The instrument for measuring scientific thinking ability is to use essay tests accompanied by rubrics. Data analysis consisted of normality test, independent t-test and ANOVA test. The results of the study showed there are diffences in the average value of scientific thinking integrated STEM class that is76.74 and STEM silos 61.64. The research is aimed at differing students ability to scientific thinking. The students are taught by using integeted STEM learning and STEM silo in the reproduction of animal plant material grade IX SMP
The cause of the histological damage of Faunus ater (gastropod mollusk) gonad has been identified in the samples from two rivers, namely Bale River and Reuleng River which flow through residential, agricultural and industrial areas. The heavy metal concentration within the tissue of Faunus ater was analyzed with Atomic Absorption Spectrophotometer (Shimadzu AA 630). Meanwhile, the histological damage on gonads was observed microscopically. Afterwards, the damage levels obtained from the two respective rivers were compared and analyzed with t-test. The results confirm the histological damage that occurred in the gonads of Faunus ater collected from the two rivers. The gonadal damage of female Faunus ater from both rivers was found not to be significantly different, observed by the number of developed and damaged oocytes. It was also found that the gonads of male Faunus ater collected from Bale Riverl, have higher quantity of spermatogenic cells, in which they experience greater necrosis than the ones from Reuleng River.
Indonesia is the one of the countries which has the richness of fermented food traditional such as Pliek-U. The natural coconut flesh was contain the components that physiologically beneficial. Nutritional quality from the meat coconut fruit were increased through the one of the fermentation processes for making the Pliek-U. This study was determine the proportion of content in Pliek-U whereas that was circulate in the community. The method for physico-chemical characteristics of Pliek-U was carried out in a laboratory using standard the basic formula. The results showed the percentage range of Pliek-U, it was obtained for 5.816-11.593% to the water content. Then, the fat content was found 34,628 - 38.998%, whereas the protein content was known as 29,164 - 34,658%. However, the proportion of the ash content was 3.606 - 5.264%. The results from the Pliek-U sample have been reported the highest percentage of the carbohydrate content (22.548%), while the lowest is 13.952%. Furthermore, Pliek-U was contains to free fatty acids in the range of 2,637 - 5,589. Then, Pliek-U samples that ready to be served have a pH content in the range of 4.083-5.589%. The output test the quality parameters from the physical and chemical properties in Pliek-U can be used as a reference or standard for the quality of Pliek-U which has been circulating for years in the aceh community.
This study aims to determine the potential for fraudulent financial statements by using fraud analysis, where fraud is a concept that explains the factors that cause someone to commit fraud, namely opportunity, pressure, rationalization and ability. Opportunity factor is proxied by using financial stability and external pressure. The opportunity factor is proxied by using industrial properties and control effectiveness. The rationalization factor is proxied by rationality and auditor turnover. Finally, the ability factor is proxied by ability. This study uses the F_Score indicator to see the potential for fraudulent financial statements. The population of this study consisted of 193 companies, with 15 samples of companies. The sampling technique used was purposive sampling. Collecting data using secondary data. Data analysis using multiple linear regression analysis method. The results showed that partially (t test) financial stability and external pressure variables had a effect on the potential for fraudulent financial statements. Meanwhile, the nature of industry, change in auditor, and capability variables have no effect on the potential for fraudulent financial statements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
