Abstract

Hasil observasi peneliti pada perkuliahan Morfologi Tumbuhan menunjukkan pertanyaan yang diajukan saat diskusi kelas jumlahnya < 3 dan hasil belajar kognitif <50%. Solusi alternatif untuk mengatasi masalah di atas, yaitu menggunakan metode pembelajaran Student Teams Achiesvement Divisions (STAD). STAD dipilih karena metode ini dapat memberikan kemudahan kepada siswa dalam memahami konsep materi pelajaran melalui diskusi kelompok. Penelitian ini ialah Penelitian Tindakan Kelas (PTK) berbasis Lesson Study (LS) atau disebut PTKLS. Subjek penelitian adalah 39 mahasiswa matakuliah Morfologi Tumbuhan. Penelitian dilaksanakan selama dua siklus, dimana tiap siklus terdiri dari dua kali pertemuan. Pada tiap siklus PTKLS meliputi tahap planning, implementing dan observing (meliputi tahap plan, do, see miliknya LS), serta reflecting. Materi yang digunakan dalam penelitian ini ialah perkembangan bunga angiospermae, polinasi, fertilisasi, buah dan bagian-bagiannya, biji dan bagian-bagiannya, pemencaran, serta perkecambahan. Hasil penelitian menunjukkan hasil belajar kognitif mahasiswa Morfologi Tumbuhan mengalami peningkatan dari siklus I (64,87) ke siklus II (65,02) sebesar 1,002257% dan keterlaksanaan pembelajaran di kelas berjalan dengan baik karena adanya plan, do, dan see miliknya LS pada fase implementing dan observing miliknya PTK.

Abstract

At present it is using digital air measurements using much better analytical functions in the field using digital measurements that have accuracy weaknesses. Developing a condensation device into the air oxygen meter uses two methods: prioritizing Saltzman and Winkler, this corresponds to the contents in the air directly with air and oxygen. Development of atmospheric atmospheric condensation equipment for example ambient air oxygen concentration measuring generator, carried out with the R2D2 development model with a calibration process based on independent sample test Calibration T-test error test with digital titration and electrochemical methods, In addition to the significance of the measurement result is sig value 0.280 > 0, 05 and the calibration measurement results of the tool developed with a digital meter tool obtained the significance of the results that the sig value of 0.254 > 0.05 there was no difference between several samples using the method used.

Abstract

Teluk Semarang merupakan teluk yang terbentang dari Kabupaten Kendal, hingga Kabupaten Demak . Teluk Semarang merupakan teluk terbesar di pantai utara Jawa Tengah dan tercatat terdapat 29 aliran sungai bermuara ke teluk ini. Banyak aktifitas manusia seperti industri, pemukiman dan pelabuhan bermuara di teluk ini yag berpotensi menjadi tekanan ingkungan bagi organisme yang hidup di teluk ini. Plankton merupakan organisme yang hidup di perairan dan sangat bergantung pada kondisi lingkungan dan merupakan sumber makanan alami bagi ikan dan organisme laut lainnya. Mengkaji kelimpahan dan indeks diversitas plankton menjadi tujuan dari penelitian ini. Penelitian dilakukan pada bulan September-Oktober 2014 pada 15 stasiun. Pengambilan sampel dilakukan sebanyak 4 kali, dengan interval waktu 2 minggu. Hasil menunjukkan bahwa jenis fitoplankton terdiri dari 6 kelas dan 37 generayang didominasi oleh jenis sedangkan zooplankton yang ditemukan terdiri dari 6 kelas dan 32 genera. Kelimpahan fitoplankton lebih banyak daripada zooplankton dan memiliki kecederungan hubungan yang berbanding terbalik. Indeks diversitas fitoplankton menunjukkan tingkat keragaman, kesetabilan komunitas dan tekanan lingkungan berada pada tingkat rendah hingga sedang, tingkat keseragaman jumlah tiap jenis tidak sama dan terdapat kecenderungan dominasi jenis tertentu. Indeks diversitas zooplankton menunjukkan tingkat keragaman, kesetabilan komunitas dan tekanan lingkungan berada pada tingkat sedang, tingkat keseragaman jumlah tiap jenis sama dan tidak terdapat kecenderungan dominasi jenis tertentu

Abstract

Acne is a kind of disease caused by Propionibacterium acne bacteria. Acne (Acne vulgaris) is a skin disease with chronicle inflammation of follicles polisebacea which generally occurs in adolescence. Treatment commonly used Medicinal Chemicals with high levels that can be harmful to the body. Alternatives that can be used as a substitute for Medicinal Chemicals is medicinal herbal of plant. Plants that can be used as herbal medicines are Kepuh and Jatropha. Kepuh contain triterpenoid, Jatropha contains alkaloid, tannin, saponin and flavonoid. The compounds have the potential as an antibacterial. This research is an experimental research laboratory that uses the diffusion method. Concentration used is 1%, 3%, 5%, 7% and 9%. Based on the results of statistical tests ANOVA difference of Kepuh leaf extract and Jatropha forPropionibacterium acne showed significant differences among treatments with significance value of 0.001. Minimum Inhibitory Concentration (MIC) Kepuh leaf extract that can inhibit the Propionibacterium acne is 3% of 0.7 mm, while the MIC of Jatropha leaves extracts for Propionibacterium acne is 4% of 0.38 mm.

Abstract

Critical thinking skills are included in high-level thinking skills that train students to think logically, scientifically, and are relevant in solving problems. These skills need to be applied in the learning of the modern era today, one of which is PBL-based TPS learning that has the thinking syntax of thinking, grouping, and sharing opinions, combined with a problem-based approach. This study aims to determine the effect of Think Pair Share (TPS) learning models based on the Problem Based Learning (PBL) approach to critical thinking skills and students' biology learning outcomes. The population in this study were students of class XI MIPA at Balung Jember High School in the academic year 2017/2018. The research sample was class XI MIPA 2 as the experimental class and class XI MIPA 1 as the control class. The results showed that the Think Pair Share learning model based on the Problem Based Learning approach had a significant effect on critical thinking skills with a significance of (p = 0,000) and was also able to improve students' biology learning outcomes in the cognitive, affective and psychomotor domains.
