<![CDATA[Fish is considered a key nutrient for a balanced diet for the growing population  around the world..fish is also superior because it is the highest natural source of omega 3 fatty acids. These fishery products are susceptible to quality degradation, therefore many use formalin as a fish preservative. The purpose of this study was to determine the level of formalin in some fresh fish. The method used is a quantitative test of formalin levels with a formalin test kit and descriptively. The sample used 5 types of fresh fish from 10 respondents. And the results of this study were that the five fresh fish samples contained formalin because the five fish were “one the fishing†fish. The most formalin content found in snapper was 3.42 g/ml.]]>

<![CDATA[Kegiatan pengabdian kepada masyarakat ini bertujuan agar guru-guru dapat menggunakan aplikasi Bandicam saat masa pembelajaran online yang dilakukan pada pandemic covid-19. Keterampilan pengelolaan pembelajaran secara daring sangat perlu didukung dengan keterampilan membuat instrumen pembelajaran daring salah satunya dengan pembuatan video pembelajaran. Video pembelajaran diperlukan sekali dalam pembelajaran daring, karena manfaatnya yaitu bersifat komunikatif dan dapat diulang-ulang, diperlambat, diperbesar. Bandicam ini merupakan salah satu media interaktif yang dapat digunakan untuk mendukung pembelajaran secara online, karena pada bandicam terdapat video dimana guru dapat menjelaskan materi dengan tepat dan jelas. Metode pengabdian menggunakan ceramah tutorial dengan bantuan Power Point, aplikasi Bandicam dan diskusi dengan peserta. Peserta kegiatan merupakan 17 orang peserta yang terdiri dari guru-guru SMA. Hasil dari kegiatan ini adalah :1) guru menjadi lebih percaya diri dan termotivasi menggunakan teknologi, 2) guru dapat merancang dan membuat video pembelajaran sederhana yang menarik sesuai tema dan kebutuhan peserta didik dengan menggunakan Bandicam 3) guru dapat merancang video interaktif dan melibatkan anak dalam pembelajaran]]>

<![CDATA[Menurunnya kualitas air pada budidaya ikan dikarenakan pemberian pelet. Oleh karena itu sangat diperlukan pemberian pakan alami untuk meningkatkan kualitas air tersebut. Larva lalat Black Soldier Fly (BSF) mempunyai kadar nutrisi dan protein sangat tinggi sehingga dapat digunakan pakan alami yang dapat diberikan kepada ikan. Metode Pelaksanaanya dengan mengetahui kualitas air saat dilakukannya budidaya ikan, pengaruh pemberian larva BSF terhadap kualitas air saat pembudidayaan, serta keuntungan pemberian pakan ternak alami larva BSF tersebut. Diadakan juga evaluasi untuk mengukur keberhasilan dari kegiatan pengabdian ini. Hasilnya menunjukkan bahwa masyarakat di Kelurahan Pardamean antusias dalam mengikuti kegiatan tersebut. Pelaksanaan sosialisasi ini memberikan pengetahuan dan keterampilan masyarakat tentang kualitas air saat pembudidayaan ikan dengan pemberian larva BSF.]]>

<![CDATA[The purpose of this research is to improve learning outcomes and chemical process skills through the Discovery Learning learning model on the reaction rate material. This research was conducted at SMA Negeri 3 Pematangsiantar in class XI MIA 2 with 29 students as the subject. This type of research is classroom action research which consists of planning, implementing actions, observing and reflecting using the Discovery Learning learning model. The test is used to measure the learning outcomes of students' initial abilities and learning outcomes, and the observation sheet is used to measure chemical process skills. Learning using the Discovery Learning model is proven to be effective in improving student learning outcomes and chemical process skills. The value achieved is still categorized in the Very Good criteria. Based on the analysis of chemical process skills, the success of the application in improving students' science process skills was 82.57% at the second meeting of the first cycle and increased again by 90.5% at the second meeting of the second cycle. The conclusion of this study is that the application of learning using the Discovery Learning model has proven to be effective in improving student learning outcomes and science process skills of SMA Negeri 3 Pematangsiantar students in class XI MIA 2.]]>

<![CDATA[The purpose of this study was to determine: (1) the effectiveness of Android-based learning media on student learning outcomes in thermochemical material; (2) Student responses to the use of Android-based learning media on thermochemical material; (3) The learning outcomes of students who are taught using Android-based chemistry learning media are the same as the KKM value. This research was conducted at Public High School 5 Medan with a total sample of 68 people. The research instrument consisted of standardized tests and questionnaires. The analytical techniques used are: (1) Two-party t test (Independent Samples T test); and (2) One Sample Test. From the results of this study, it was found that: (1) Anroid-based chemistry learning media was effective on student learning outcomes on thermochemical material, with a t-test of 7.063 which was greater than t-table of 2.00. Then based on the Gain Score, the t-test of 6.843 was obtained, which was greater than the t-table of 2.00; (2) Student responses "Very Interesting" with percentages of 92.27%, 93.93% and 92.12%, respectively, on the use of anroid-based learning media in thermochemical material; (3) The learning outcomes of students who are taught using android-based chemistry learning media are not the same as the KKM value, where , tcount (2.126) > ttable (2.032), means that it has a positive effect on KKM]]>
