This research aims to increase the motivation and mathematics learning outcomes of class X students at SMA Negeri 2 Medan through the application of the model Problem-Based Learning (PBL) combined with the use of Quizizz technology. This research uses the Classroom Action Research (PTK) method with the Kemmis and McTaggart model, which consists of four stages: planning, implementation, observation and reflection. The research subjects were 36 class X students, with instruments in the form of observation sheets, questionnaires and tests. The research results show that the implementation of PBL assisted by Quizizz is effective in increasing student motivation and learning outcomes. In the first cycle, 77.78% of students showed high learning motivation, and this figure increased to 100% in the second cycle. Improvements in student learning outcomes were also seen in cognitive, affective and psychomotor aspects, which experienced significant increases from the first cycle to the second cycle. The PBL model allows students to be more active in learning by presenting contextual mathematical problems, so that abstract material becomes easier to understand. In addition, the use of Quizizz creates an interactive and fun learning atmosphere through game elements. This research concludes that the application of PBL assisted by Quizizz is not only able to improve student learning outcomes holistically, but also motivates them to actively participate in learning. This approach is relevant for improving the quality of mathematics learning, especially in the digital era

Penelitian ini bertujuan menguji kemampuan spesies dari kelas Bivalvia terhadap tingkat pencemaran air laut yang merupakan masalah klasik dan tidak pernah ada habisnya. Tidak hanya itu, hewan bercangkang (Bivalvia) ini pun mampu menyaring kandungan logam berbahaya dari komponen baja paduan yang memiliki tingkat racun sangat tinggi yang sering terkandung dalam limbah pabrik, yaitu merkuri. Namun, mungkin juga tidak semua spesies dari kelas Bivalvia memiliki kemampuan yang sama dalam menyerap atau menyaring air laut. Bagi nelayan, mereka hanya perlu mencari kerang kemudian hasilnya dikumpulkan ke pengepul lalu dijual, tanpa mereka ketahui betapa pentingnya kemampuan kerang ini bagi ekosistem, terutama dalam kemampuannya menyaring air laut yang tercemar. Berdasarkan latar belakang masalah tersebut, peneliti bertujuan untuk menguji secara langsung dan melihat kemampuan beberapa spesies yang umum atau terkenal yang banyak ditemukan oleh nelayan di pantai timur provinsi Sumatera Utara. Pengujian akan dilakukan secara langsung terhadap 10 jenis kerang yang banyak dijumpai di pantai timur Sumut yaitu Kerang Besar, Kerang Batik/Salome, Kerang Biru, Kerang Kapak, Kerang Kecil, Kerang Belang/Tiger, Kerang Panjang, Merak Kerang, Kemudi Kapal Kerang, Kerang Mutiara. Ke-10 jenis kerang tersebut dipilih secara purposive berdasarkan jumlah terbesar dan ukuran cangkang terbesar. Penelitian ini akan menggunakan teknik analisis Duncan One Way Anova atau Rancangan Acak Lengkap. Pengujian sampel akan dilakukan pada air laut di Pantai Mangrove Percut Sei Tuan. Hasil pengujian akan memberikan kesimpulan mengenai implikasi atau keterlibatan Bivalvia dalam membantu mengatasi pencemaran air laut dan pengaruhnya terhadap ekosistem dan manusia yang mengkonsumsinya. Hasil penelitian ini juga akan bermanfaat sebagai acuan dan sumber acuan penelitian selanjutnya untuk penelitian selanjutnya dalam menggali potensi bioindikator dari filum invertebrata lainnyaKata Kunci : Implikasi, Bivalvia, Biofilter, Pencemaran, Paluh Merbau

This study aims to: 1) recognize fruit flies (Drosophila melanogaster), 2) morphologically distinguish adult fruit fly sex, 3) study the growth of fruit fly populations. The practicum was held on August 20, 2019 in the Biology Education Laboratory FKIP UISU. The working principle of practicum is making food as a medium for fruit fly culture (a mixture of bananas, cassava tape, benzoate), etherization and observation, observing the growth of fruit fly populations. Observations were made by counting the number of live flies and dead flies, the sex ratio of flies. Observations were carried out every day, for 15 days (20 August 2019 - 3 September 2019). The results of the analysis show that: 1) population growth of Drosophila melanogaster includes logistic growth models with S-shaped curves, 2) sex of adult fruit flies can be morphologically distinguished through body size, abdominal shape, genital comb and external genital organs in the abdomen. Based on the results and discussion, the following conclusions are obtained: 1) fruit flies including insects undergoing perfect metamorphosis (egg phase, larvae, pupa, imago), 2) differences in adult fruit fly sex can be seen from body size, abdomen shape, presence of genital comb, external genital organs in the abdomen, 3) population growth of fruit flies including logistic growth models in the form of S curves, influenced by environmental factors
