Abstract

AbstrakPenelitian ini dilakukan untuk mengetahui Pengaruh Model Pembelajaran Inquiry Training Terhadap Hasil Belajar Siswa Kelas X Pada Materi Larutan Elektrolit Dan Nonelektrolit Di SMA Negeri 3 Kepulauan Sula. Jenis penelitian yang digunakan adalah penelitian eksperimen dengan desain penelitian yaitu One Group Pretest Posttest Desain. Populasi dalam penelitian adalah seluruh siswa siswi kelas X SMA Negeri 3 Kepulauan Sula yang berjumlah 25 orang dengan teknik pengambilan sampel yaitu sampling jenuh. Instrumen yang digunakan dalam penelitian ini yaitu instrumen tes berupa soal essay sebanyak 10 nomor. Data yang diperoleh selanjutnya dianalisis menggunakan SPSS 29.0. Hasil uji hipotesis dalam penelitian ini diperoleh dari uji Paired Sample T Test, thitung  ttabel (12,972  1,710) maka Ha diterima dan HO ditolak. Sehingga model pembelajaran Inquiry Training berpengaruh terhadap hasil belajar siswa, dengan besar pengaruh yang diperoleh dari uji nilai gain sebesar 0,44 dengan kategori sedang. Kata Kunci: Inquiry Training, Hasil belajar, Larutan Elektrolit dan NonelektrolitAbstractThis research was conducted to determine the effect of the Inquiry Training Learning Model on the Learning Outcomes of Class X Students in the Material of Electrolyte and Non-electrolyte Solutions at SMA Negeri 3 Kepulauan Sula. The type of research used is experimental research with a research design that is One Group Pretest Posttest Design. The population in the study were all 25 students of class X SMA Negeri 3 Sula Archipelago, using a sampling technique, namely saturated sampling. The instrument used in this study was a test instrument in the from of 10 numbers of essay questions. The data obtained were then analyzed using SPSS 29.0. The results of  hypothesis testing in this study were obtained from the Paired Sample T Test, tcount  ttable (12.972  1.710) then Ha was accepted and Ho was rejected. So that the Inquiry Training learning model has an effect on student learning outcomes, with a large influence obtained from the gain value test of 0.44 in the medium category. Keywords:Inquiry training, learning outcomes, electrolyte and nonelectrolyte

Abstract

Cooking oil is a basic need for everyday people, approximately 80% of the people of Ternate City use cooking oil repeatedly for cooking in order to save costs. The repeated use of used cooking oil or waste cooking oil with high heating produces free fatty acids, carbonyl compounds, peroxides, decreases the value and nutrition of fried foods, so that over time it has an impact on health. Efforts to process used cooking oil in the City of Ternate by saving costs but not endangering health really need to be carried out by using the typical North Maluku banana peel (Musa sp) as a natural adsorbent to purify used cooking oil. Starting from the preparation of tools and materials, the processing of banana peels, mixing the ingredients in the adsorbent, testing the levels of free fatty acids, determining the levels of free fatty acids and the characteristics of the clusters of banana peels using the Fourier Transform-Infra Red. In this study, the percentage reduction in free fatty acid levels was 0.833%, which was originally 1.882%. These results indicate that the refining of used cooking oil using banana peels is close to the Free Fatty Acid (FFA) value regulated in the Indonesian National Standard (SNI) of 0.3%. Keywords: Used cooking oil, peel of banana's mouth duck (Musa sp), refining.
