This study aims to identify differences in learning outcomes and interests of students who are taught using Macromedia Flash and Powtoon media for electrolyte and non-electrolyte solutions. The population of this study were all students of class X MIPA, totaling 3 classes. Sampling was done by purposive sampling. Data on student learning outcomes were examined for validity, difficulty, discriminating power, and reliability using an objective test instrument consisting of 20 questions. To measure student interest, the data used a questionnaire filled in by the observer. Pretest, posttest, and students' interest in the two experimental classes were determined based on normality test data and homogeneity test. In the Experimental Class I and Experimental Class II, it was found that the pretest, posttest, and students' interest in the two experimental classes were normally distributed and homogeneous. Next, a hypothesis test was carried out using a two-party Independent Sample T-Test. To test the first hypothesis, the results were sig. 0.024 (sig. <0.05) and to test the hypothesis II, the results were sig. 0.000 (sig. <0.05), which means that there is a significant difference in the learning outcomes and interests of students taught with Macromedia Flash Media using the Problem Based Learning model compared to the learning outcomes and interests of students taught with Powtoon Media using the Problem Based Learning model in the material electrolyte and non-electrolyte solutions.

This study aims to determine the learning outcomes of students who are taught using a problem based learning model using powerpoint are higher than the learning outcomes of students who are taught conventionally. This research was carried out at SMA Negeri 1 Lawe Sigala-gala, Aceh Tenggara in December 2021. From the results of the study, the results of the study in the experimental class wereobtained with an average pretest score of 25.29 and for the posttest in the experimental class, the average score was 80, 88. While the control class obtained an average value of 24.41 and for the posttest control class obtained an average value of 74.12. Students' learning interest before being given treatment in the experimental class obtained an average value of 69.59, for the control class the average value was 65.00. After being treated in the experimental class, the average value was 80.00 and in the control class, the average value was 70.76. The normalized N-Gain value for students in the experimental class is higher than the value in the control class, namely 0.6842> 0.6315 or the percentage of N-Gain in the experimental class is 68% and the control class is 63%. And for the N Gain value of student interest in the experimental class is higher than the value in the control class, namely 11.111> 0.0625 or the percentage of N-Gain in the experimental class is 11% and the control class is 6.25%.

This study aims to determine whether there is a difference between the learning outcomes of students taught with Problem Based Learning and Discovery Learning models in terms of higher order thinking skills (HOTS) on chemical equilibrium material. The study population was all students of class XI IPA SMA Negeri 11 Medan. The sample in this study consisted of 2 experimental classes. The instrument used in the study was a test instrument. Before hypothesis testing, normality test and homogeneity test were conducted first. In the normality and homogeneity test in each class sample, the results showed that the data were normally distributed and homogeneous. Furthermore, the N-Gain test was carried out, the results of data processing showed that the increase in learning outcomes in experimental class I was in the medium category, and in experimental class II was in the high category. Based on the results of data processing with the Independent Sample T-Test test for hypothesis testing, the Sig value is obtained. = 0.017 at the 5% significance level (α = 0.05). Because the value of Sig. α (0.05), then in this study the alternative hypothesis (Ha) is accepted.

MAN Binjai merupakan salah satu sekolah yang gencar mendukung gerakan madrasah sehat, bersih dan cinta lingkungan. Salah satu limbah yang banyak terdapat dilingkungan madrasah adalah limbah minyak jelantah dari kegiatan memasak di kantin. Limbah minyak jelantah dapat mencemari tanah dan menyumbat saluran air jika tidak ditangani dengan benar. Kegiatan sosialisasi dan edukasi tentang pemanfaatan minyak jelantah penting dilakukan sebagai Upaya mengurangi limbah serta pemanfaatan ulang limbah minyak jelantah menjadi produk yang bernilai jual. Alternatif pemanfaatan minyak jelantah antara lain menjadi lilin aromaterapi. Kegiatan pengabdian kepada masyarakat (PkM) yang dilakukan bertujuan meningkatkan pemahaman dan keterampilan kelompok mitra dalam pemanfaatan limbah minyak jelantah. Metode yang dilakukan pada kegiatan PkM ini adalah sosialisasi, edukasi dan pelatihan secara langsung pembuatan lilin aromaterapi berbasis kulit jeruk dari minyak jelantah. Hasil kegiatan PkM ini meningkatkan pengetahuan kelompok mitra terkait minyak jelantah dan dampaknya sebesar 11,11%, pengetahuan tentang pemanfaatan minyak jelantah meningkat sebesar 77,78%, pengetahuan tentang pemanfaatan minyak jelantah menjadi lilin aromaterapi meningkat sebesar 74,07% dan pengetahuan pemanfaatan kulit jeruk menjadi pewangi pada lilin aromaterapi meningkat sebesar 33,33%. Kegiatan PkM yang dilaksanakan juga mendapat respon positif dari kelompok mitra yang dianalisis menggunakan angket kuesioner.
