    This study aims to determine the increase in students' cognitive abilities through jigsaw learning. This research is a classroom action research using two cycles. The subjects in this study were students of SMA Negeri 4 Kota Serang class XI MIPA in the odd semester of the 2018/2019 academic year. The object of research is students' cognitive abilities. Data on students' cognitive abilities were collected using a cognitive ability test instrument on the concept of plant tissue structure. Data were analyzed descriptively qualitatively. The results showed an increase in students' cognitive abilities before and after the action research. This action research is declared successful if it has achieved a cognitive average score at the minimum that is equivalent to the KKM value = 70. The results showed that the average value of students' cognitive abilities before the research action was 36.32, then increased to 48.23 after the first cycle, and increased again to 72.86 at the final session (cycle II). The conclusion of this study is that the application of the jigsaw learning model in learning is able to improve students' cognitive abilities on the concept of plant tissue structure. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan kognitif siswa melalui pembelajaran jigsaw. Penelitian ini merupakan penelitian tindakan kelas dengan menggunakan yang dilakukan dalam dua siklus. Subjek dalam penelitian ini adalah siswa SMA Negeri 4 Kota Serang kelas XI MIPA semester ganjil tahun pelajaran 2018/2019. Objek penelitian adalah kemampuan kognitif siswa. Data kemampuan kognitif siswa dikumpulkan menggunakan instrumen tes kemampuan kognitif pada konsep struktur jaringan tumbuhan. Data dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan adanya peningkatan kemampuan kognitif siswa sebelum dan sesudah penelitian tindakan.  Penelitian tindakan ini dinyatakan berhasil bila telah mencapai nilai rata-rata kognitif secara klasikal minimal setara dengan nilai KKM=70. Hasil penelitian menunjukkan bahwa nilai rata-rata kemampuan kognitif siswa sebelum tindakan penelitian sebesar 36,32, kemudian meningkat menjadi 48,23 setelah siklus I, dan meningkat lagi menjadi 72,86 pada sesi akhir (siklus II). Kesimpulan dari penelitian ini adalah penerapan model pembelajaran jigsaw dalam pembelajaran mampu meningkatkan kemampuan kognitif siswa pada konsep struktur jaringan tumbuhan

    Pharmacists have one of the tasks, namely dispensing non-sterile preparations by making pulveres preparations. Making pulveres preparation cannot be separated from the risk of medication errors caused by incompatibility. This study aims to determine the incompatibility of antibiotic pulveres preparations with corticosteroids. This study is experimental, the sample used is a mixture of antibiotics and corticosteroids in the form of pulveres. The antibiotics used were amoxicillin, cefixim, and cefadroxil, while the corticosteroids used were dexamethasone and methylprednisolone. The research was conducted in the Setia Budi University laboratory, by looking at organoleptic, moisture test, and active substance content test using UV spectrophotometer instrument. The data obtained were analysed descriptively and displayed in the form of tables and percentages. This study was based on the prescription of children's pulveres preparations at clinic X in Sukoharjo, which mostly prescribed antibiotics with corticosteroids. Experiments were carried out in accordance with the literature test and it was found that there was no organoleptic change when the tablet preparation was crushed. Moisture test results showed that amoxicillin has hygroscopic properties that cause the powder to become moist. Amoxicillin pulveres with corticosteroids have high moisture content. The cefixime pulveres with or without cortocisteroid combination also had high moisture content. The allowable moisture content is < 5%. The test results showed that there was a difference in absorbance values between antibiotics in single form and a combination of antibiotics and corticosteroids Keywords: antibiotic, incompatibility, corticosteroid, pulveres Abstrak Farmasis memiliki salah tugas yaitu dispensing sediaan non steril dengan membuat sediaan pulveres. Pembuatan sediaan pulveres tidak lepas dari risiko medication error yang disebabkan adanya inkompatibilitas. Penelitian bertujuan mengetahui inkompatibilitas sediaan pulveres antibiotika dengan kortikosteroid. Penelitian ini merupakan eksperimental, sampel yang digunakan adalah campuran antibiotika dan kortikosteroid dalam bentuk pulveres. Antibiotika yang digunakan yaitu amoksisilin, sefixim, dan sefadroksil, sedangkan kortikosteroid yang digunakan yaitu dexametason dan metilprednisolon. Penelitian dilakukan dilaboratorium Universitas Setia Budi, dengan melihat organoleptis, uji kelembaban, dan uji kadar zat aktif dengan menggunakan instrument spektofotometer UV. Data yang didapatkan dianalisis secara deskriptif dan ditampilkan dalam bentuk tabel dan persentase. Penelitian ini berdasarkan peresepan sediaan pulveres anak di klinik X di Sukoharjo yang sebagian besar resep antibiotika dengan kortikosteroid. Eksperimen dilakukan sesuai dengan uji literature dan didapatkan tidak ada perubahan secara organoleptik ketika sediaan tablet digerus. Hasil uji kelembaban menunjukkan bahwa amoksisilin memiliki sifat higroskopis yang menyebabkan serbuk menjadi lembab. Pulveres amoksisilin dengan kortikosteroid memiliki kadar kelembapan yang tinggi. Pulveres sefiksim dengan atau tanpa kombinasi kortokisteroid juga memiliki kadar kelembapan tinggi. Kadar kelembapan yang diperbolehkan yaitu &lt; 5%. Hasil uji menunjukkan adanya perbedaan nilai absorbansi antara antibiotik dalam bentuk tunggal dengan kombinasi antibiotika dan kortikosteroid. Kata Kunci: antibiotika, inkompatibilitas, kortikosteroid, pulvere

    This study aims to determine the differences in students' mathematical representations through the Problem Based Learning (PBL) model assisted by GeoGebra and Realistic Mathematics Education (RME) models, differences in the mathematical representation of students through GeoGebra-assisted PBL models with the RME model in terms of learning styles Field Independent (FI) and Field Field (FI) Dependent (FD). The research used was Quasi-experimental research. The population is grade XII students, and the sample used is the science class 1, and science 2. The data were collected by tests. Data analyzed using variance and independent t-test. This research results in a difference between students' mathematical representation through the GeoGebra-assisted PBL model and the RME model. The difference in students' mathematical representation through the GeoGebra-assisted PBL model and the model of the RME in terms of the FI learning style. At the same time, for FD, there is no significant difference.</span
