PENERAPAN TEKNIK PROBING DAN PROMPTING TERHADAP RASA INGIN TAHU DAN HASIL BELAJAR SISWA PADA MATERI REAKSI REDUKSI OKSIDASI BERBANTU GOOGLE FORM PADA MASA PANDEMI COVID 19 DI SMA NEGERI 4 PADANGSIDIMPUAN

The application of probing and prompting techniques is the application of science and technology by conducting investigations or examinations by relating questions in the form of cause and effect aimed at encouraging or guiding the achievement of satisfactory learning outcomes. The application of probing and prompting techniques as a source of independent learning because it requires the involvement of students in exploring and guiding learning. The application of probing and prompting techniques is expected to make students more interactive in learning. So that student curiosity can increase in accordance with the expected learning objectives. This research was motivated because probing and prompting techniques had never been applied at SMA Negeri 4 Padangsidimpuan. This study aims to determine whether there is an influence of the application of probing and prompting techniques on students' curiosity and learning outcomes on oxidation reduction reaction material in class X MIA SMA Negeri 4 Padangsidimpuan. The data on the curiosity test of students in the experimental class was with an average of 49.37 and in the control class was with an average of 49.17, so students' curiosity was higher in the experimental class. Then classes that used Probing and Promting techniques obtained an average learning outcome test of 36.47 to 79, so there was an increase

UJI KELAYAKAN PENILAIAN PROYEK BERBASIS PENDEKATAN SAINTIFIK UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS ABAD 21 MAHASISWA PADA MATA KULIAH METODOLOGI PENELITIAN

Research methodology is a required subject that must be taken by IPTS students in order to conduct their thesis guidance. It requires students to raise an education problem to carry out the introduction of research proposal and implementation. And so the students need to think critically. Basically, students have been difficulties to formulate problems that can be raised as a research. This requires a scientific or known as a saintifical approach and project assesment in order to students can be trained to work out proposals and research reports systematically using the scientific method. The use of a scientific-based project assessment instrument aimed ata valid . saintifical approach assesment of projects increasing 21st students’ critical thinking skills  in research methodology courses. The use of this asssment instrument can be used for further decision-making in depelovment of future study processes of vresearch methodology. It is continuously carried out, therefore, makes a continual improvement-process. The method of research used development research with an addie model. The result of this study indicate that the assessment of the proscience-based project developed have been declared valid to increase student critical thought capability of 21st –century students on research methodology courses at IPTS

ANALYSIS OF MINERAL CONTENT IN ZAM-ZAM WATER CIRCULATION IN PADANGSIDIMPUAN CITY

This research was motivated by the existence of Zam-zam water trade in Padangsidimpuan City, while the Saudi Arabian government prohibited the export of Zam-zam water. This causes people to suspect that the quality of Zam-zam water circulating in the market is not the same as the Zam-zam water found in Mecca. Therefore, research needs to be carried out to answer these concerns. This research aims to analyze the mineral content of labeled packaged Zam-zam water circulating in Padangsidimpuan City compared with Zam-zam water brought from Mecca City. The mineral concentrations tested were sodium and chloride. This research uses laboratory experimental methods, including quantitative analysis. According to the type of research, the data analysis technique used is to compare the concentration of each mineral in the water labeled Zam-zam with the mineral concentration in the Zam-zam water used as a control. The research results showed that Zam-zam water obtained from Mecca City contained 42.4 mg/L chloride, 2.06 mg/L sodium, while the labeled Zam-zam water circulating in Padangsidimpuan, namely sample 1, contained 160.7 mg/L chloride. sodium 2.06 mg/L in sample 2 contains 50.5 mg/L chloride, sodium 2.17 mg/L. The three Zam-Zam samples circulating in Padangsidimpuan that have been tested show that the quality of Zam-Zam water is suitable for consumption based on determining a good water quality test, namely at the suitability threshold
