Abstract

Pembelajaran yang dilakukan khususnya pada materi ajar sistem imun masih didominasi oleh pendidik yang di dalamnya siswa hanya menerima saja materi yang diberikan tanpa mencari tahu sendiri terlebih dahulu, sehingga dalam aplikasi kehidupannya siswa masih sulit untuk memahami materi yang diberikan karena siswa terbiasa hanya menerima saja dan tidak memberdayakan kemampuan mereka dalam mencari suatu masalah yang ada. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran group investigation terhadap hasil belajar siswa. Model pembelajaran GI merupakan model pembelajaran yang melibatkan siswa dalam kelompok untuk mencari suatu permasalahan yang diperbincangkan dengan mengangkat topik-topik yang luas dalam proses belajar mereka serta masisng-masing kelompok dapat berbagi pengetahuan satu sama lain. Metode penelitian ini menggunakan metode penelitian eksperimen semu yang menganalisis pengaruh antara variable X dan variable Y berdasarkan perbedaan hasih pencapaian hasih belajar siswa pada kelas eksperimen dan kelas kontrol. Jumlah sampel pada kelas XI IPA1 dengan jumlah 26 siswa sebagai kelas eksperimen dan jumlah sampel pada kelas XI IPA2 dengan jumlah siswa 26 siswa sebagai kelas kontrol. Data hasil penelitian di analisis dengan uji-t yang menggunakan taraf nyata α = 0,05 dengan data yang diperoleh yaitu thitung= 7,53 sedangkan nilai tTabel = 2,00 sehingga H0 ditolak dan H1 diterima. Kesimpulan yaitu model pembelajaran GI berpengaruh terhadap hasil belajar siswa pada materi sistem imun.Kata Kunci: Pembelajaran Group Investigation, Hasil Belajar, Sistem Imun.

Abstract

The study aimed to identify the content of the triterpenoid saponin compound from Barringtonia asiatica seeds collected from coastal of Malalayang beach, Manado, North Sulawesi. The method of extraction was the maceration with methanol solvent. The identification of the isolate was by thin layer chromatography, column chromatography, and GCMS. The phytochemistry test result of B. asiatica seed extract contained the compounds of alkaloid, saponin, and tannin. Then, the compound was separated by a thin layer chromatography method with a solvent system of methanol:chloroform:water. It produced three nodes that were spread around polar (Rf 0.24), semipolar (Rf 0.6) and non-polar (Rf 0.78) areas. Meanwhile, the process of column chromatography could only separate two chemical components namely semipolar (Rf 0.6) and polar (Rf 0.76). The identification with GCMS resulted in three compounds of Triterpenoid saponins, namely 2.4-bis-(1.1-dimethyl ethyl); 4-Dodecylphenol; and 2.6 bis-(1.1-dimethyl ethyl-4-methyl).

Abstract

Mujair fish (Oreochromis mossambicus) is a freshwater fish that is commonly consumed. This is due that they are easily found and obtrained and with a price in fresh markets that are relatively cheap. Unfortunately, this fish happens to be a very perishable commodity, due to it’s sensitiveness to spoilage because of its high protein content and moisture content. Pangi seeds (Pangium edule) is known to contain tanines, natural polyphenols that inhibits microorganisms through their cell wall permeability. The purpose of this research was to test the potential of pangi seeds crude extract as natural pangi seed toxiti preservatives on mujair fish, shelf life potential on mujair fish. This was achieved by marinating the fish in crude pangi seed extracts at concentrations of 0% (control), 5% and 10% and then store for 4 days at room temperature. Parameters tested on this research includes cyanide identification BSLT toxicity testing and fish spoilage (degradation) through protein changes and pH. Results of this research indicated that pangi seeds crude extract does not contain any cyanide of whatsoever, pangi seed crude extract toxicity testing indicated thatit was not toxic to a concentration of 128233mg/L, meanwhile protein analysis indicated that the optimum concentration of pangi seed crude extract to inhibit fish spoilage is 10% while in terms of pH degradation, the optimum concentration was 5%.

Abstract

Diabetes mellitus is a chronic metabolic syndrome disorder of carbohydrates, lipids, and fats caused by insulin deficiency in the body causing blood glucose above the normal threshold (hyperglycemia). Tome-tome (Flacourtia inermis, Roxb) contains anthocyanins which have the ability to lower blood sugar levels. This study aimed to determine the effectiveness of the ethanolic extract of tome-tome fruit (Flacourtia inermis, Roxb) and to see what dose and day treatment was most effective against diabetes in white rats (Rattus norvegicus) induced by alloxan. The place of research was carried out at the Pharmacy Laboratory of Trinita University, Manado with a research time of 3 months. The test animals used were 25 white rats (Rattus norvegicus) divided into 5 treatment groups, namely normal control, negative control, positive control (glibenclamide) and ethanol extract of tome-tome fruit with doses of 150 mg/kgBW and 300 mg/kgBW. Blood glucose measurements were carried out on day 1, day 7, and day 14. The results showed that the effectiveness of tome-tome fruit ethanol extract against alloxan-induced diabetic rats decreased blood glucose levels. A dose of 150 mg/kgBW ethanol extract of tome-tome fruit was more effective in reducing blood glucose levels compared to a dose of 300 mg/kgBW rats.

Abstract

This study tries to apply an inquiry approach, which is a constructivist learning method. In this approach, students are given a problem in a particular situation or phenomenon that stimulates them to think critically, analyze and even draw conclusions based on prior knowledge. Through this approach, students are invited to study a problem that must be observed and scrutinized, so that it is hoped that understanding of course concepts in learning activities can increase. In the context of plant tissue culture courses, the learning methods that have been applied so far are less varied, and this seems to have a negative impact on student learning outcomes. Therefore, this study aims to examine the effect of the application of the guided inquiry method on the learning outcomes of semester VI students in that course. It is hoped that with the application of the inquiry method, students will experience an increase in understanding of concepts and skills in plant tissue culture courses. And of course, this increase is expected to have a positive impact on overall learning outcomes. This study used a quasi-quasi experimental design with subjects in the sixth semester of biology students. Data obtained through pretest and post-test, and the hypothesis was tested using the t test. The results of the data analysis show that there is a significant effect of the application of the inquiry method on improving student learning outcomes in tissue culture engineering courses. This can be concluded from the calculated t value which is greater than t table at a significance level of 0.05. Thus, it can be confirmed that the inquiry approach contributes positively to improving student learning outcomes in these courses.
