Abstract

AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh model problem based learning (PBL) terhadap hasil belajar siswa kelas X SMA Negeri 7 Halmahera Timur pada materi reaksi redoks. Jenis penelitian ini adalah quasi experimental design yaitu  One-Group Pretest Prossttest Design. Pengambilan sampel menggunakan sampling jenuh. Sampel penelitian adalah siswa kelas X SMA Negeri 7 Halmahera Timur yang berjumlah 15 orang. Data hasil penelitian diperoleh dengan menggunakan lembar observasi  aktifitas siswa (ranah afektif dan ranah psikomotorik) dan tes hasil belajar siswa berupa soal  uraian. Berdasarkan hasil analisis data dengan analisis Uji Wilcoxon Signed Ranks Test diperoleh kesimpulan bahwa terdapat pengaruh model problem based learning (PBL) terhadap hasil belajar siswa kelas X SMA Negeri 7 Halmahera Timur pada materi reaksi redoks dengan nilai signifikasi 0,001 0,05 dengan presentase nilai gain sebesar 50 % dengan kategori sedang.Kata Kunci :        Model Problem Based Learning (PBL), Hasil Belajar, Reaksi Redoks Abstract This study aims to determine the effect of the problem based learning (PBL) model on the learning outcomes of class X students of SMA Negeri 7 Halmahera Timur on redox reaction material. This type of research is a quasi-experimental design, namely One-Group Pretest Prossttest Design. Sampling using saturated sampling. The research sample was 15 students of class X SMA Negeri 7  Halmahera Timur. The research data were obtained by using student activity observation sheets (affective and psychomotor domains) and student learning outcomes tests in the form of description questions. Based on the results of data analysis with the Wilcoxon Signed Ranks Test analysis, it was concluded that there was an effect of the problem based learning (PBL) model on the learning outcomes of class X students of SMA Negeri 7 Halmahera Timur on redox reaction material with a significance value of 0.001 0.05 with a percentage gain value. by 50% in the medium category.Keywords:Model Problem Based Learning (PBL), Learning Outcomes, Redox Reaction.

Abstract

Abstrak Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan media pembelajaran yaitu flashcard sistem periodik unsur terhadap daya retensi peserta didik kelas X SMA. Metode penelitian yang digunakan adalah metode kuasi eksperimen, yang dilakukan di SMA N 1 Kasihan, Kab. Bantul, Daerah Istimewa Yogyakarta. Hasil penelitian pangkat eksponensial kelas kontrol (-0,0169x) lebih besar dari pangkat eksponenensial kelas eksperimen (-0,0067x). Ini berarti penurunan daya retensi pada kelas kontrol lebih besar jika dibandingkan dengan kelas eksperimen. Artinya, dapat disimpulkan bahwa penggunaan flashcard sistem periodik unsur dapat memperkecil penurunan daya retensi peserta didik.Kata kunci: daya retensi, flashcard, sistem periodik unsurAbstract This study aims to analyze the effect of the use of learning media, namely the periodic system of elements flashcard on the retention power of class X SMA students. The research method used is a quasiexperimental method conducted at SMA N 1 Kasihan, Kab. Bantul, Special Region of Yogyakarta. The results of the study showed that the exponential power of the control class (-0.0169x) was greater than that of the experimental class (-0.0067x). This means that the decrease in power retention in the control class is greater when compared to the experimental class. That menas that the use of the periodic system of elements flashcard cannot reduce the students' retention power.Keywords: flashcard, periodic system of elements, retention

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.
