<![CDATA[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.]]>

Populasi pada penelitian ini, yaitu mahasiswa Program Studi Pendidikan Kimia FMIPA jenjang S1 Universitas Negeri Yogyakarta. Sampel penelitian ini berjumlah 320 calon guru kimia. Sampel penelitian ditentukan menggunakan teknik convenience sampling. Data efikasi diri dikumpulkan menggunakan angket. Validitas teoritis dilakukan untuk melihat kelayakan instrumen yang digunakan. Validitas teoritis dilakukan oleh tiga ahli pendidikan kimia UNY Yogyakarta untuk memberikan saran yang mendukung peningkatan kualitas instrumen penelitian. Hasil penelitian menunjukkan bahwa mahasiswa yang menempuh kuliah di semester enam dan empat memliki efikasi diri yang lebih dominan pada kategori baik dan kategori sangat baik. Dibandingkan dengan mahasiswa calon guru kimia yang menempuh kuliah di semester dua menunjukkan efikasi diri yang lebih rendah. Kata Kunci :Efikasi Diri, Laju Reaksi Abstract This study aimed to analyze the self-efficacy profile of pre-service chemistry teacher on rate of reaction topic who attend lectures in semesters two, four, and six at the Chemistry Education Study Program, State Islamic University (UIN) Sunan Kalijaga in the Special Region of Yogyakarta. This type of research is a cross-sectional survey design. The population in this study, namely students of the Chemistry Education Study Program, Faculty of Mathematics and Natural Sciences, Yogyakarta State University undergraduate level. The sample of this research was 320 chemistry teacher candidates. The research sample was determined using a convenience sampling technique. Self-efficacy data was collected using a questionnaire. Theoretical validity was done to see the feasibility of the instrument used. Theoretical validity was carried out by three chemistry education experts at UNY Yogyakarta to provide suggestions that support improving the quality of research instruments. The results of the study show that students who study in semesters six and four have more dominant self-efficacy in the good and very good categories. Compared to prospective chemistry teacher students who take courses in the second semester, they show lower self-efficacy. Keywords:self-efficacy, rate of reaction topic]]>

<![CDATA[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.  ]]>
