Abstract

This study aimed to determine the increase in student activity and learning outcomes in learning mathematics on the material of a two-variable system of linear equations. The background things are the low learning outcomes of students' mathematics. This is due to the use of an inappropriate teaching method approach. To overcome this, improvements can be made by applying a problem-solving learning model. This type of research is classroom action research (CAR). The subjects of this study were students of class X SMA Negeri 2 Jerebuu, totalling 14 people, consisting of 5 female students and 9 male students. Factors studied in the form of increased activity and student learning outcomes. Data collection methods used in this study were observation and test techniques. Data analysis used descriptive qualitative analysis with percentage technique. The results showed that the application of the problem-solving learning model could improve student activity and learning outcomes. Student learning activities in the first cycle obtained a total score of 29 with a percentage of 58% and were categorized quite well. Then it increased in the second cycle with the total score obtained being 43 and the percentage is 86% and categorized as very good. Student learning outcomes in the first cycle obtained an average of 70 with 50% of students achieving the Minimum Completeness Criteria (KKM). Then it increased in the second cycle with an average of 85.71 with 100% of students achieving KKM.

Abstract

Media pembelajaran interaktif merupakan salah satu aspek yang mendukung terjadinya proses pembelajaran yang menarik dan menyenangkan. Classpoint merupakan salah satu media pembelajaran yang dapat memenuhi aspek tersebut. Penelitian ini bertujuan untuk mengetahui persepsi mahasiswa terhadap penggunaan media pembelajaran interaktif Classpoint pada kegiatan perkuliahan. Pendekatan yang digunakan dalam penelitian adalah pendekatan kuantitatif dekriptif dengan menggunakan angket. Sebanyak 19 orang mahasiswa semester IV pada program studi Pendidikan Biologi Universitas Flores yang mengikuti mata kuliah Zoologi Invertebrata diberikan angket yang berisi 16 butir pernyataan yang mewakili aspek motivasi, kegunaan, dan aspek kognitif serta psikomotorik. Data mahasiswa yang terkumpul dipersentasikan dengan menggunakan persentase kriteria skor angket persepsi. Hasil penelitian menunjukkan bahwa mahasiswa memberikan respons positif terhadap media pembelajaran interaktif Classpoint dengan kriteria sangat setuju atau rentang persentase respons 73,68% sampai 93,68%. Tanggapan positif yang diberikan terhadap media Classpoint ini dikarenakan adanya beberapa fitur menarik yang medukung fungsi Classpoint sebagai media pembelajaran interaktif. Implikasi dari penelitian ini ialah media interaktif Classpoint dapat dijadikan sebagai salah satu referensi media belajar di kelas, khusus dalam meningkatkan motivasi dan keaktifan mahasiswa dalam belajar.

Abstract

Begonia kelimutuensis is an endemic species of Kelimutu National Park, Ende Regency, East Nusa Tenggara. Since it was designated as an endemic plant, this species has become one of the attractions for visitors to the Kelimutu National Park. However, research studies on this species are not widely known, so further research is needed. This study aims to determine the structure of the vegetation, the composition of plant species in the habitat of Begonia kelimutuensis and the Important Value Index (INP). The research method used is the plotted line method, with 20m x 20m plots used to collect tree species data, 10m x 10m plots used to collect pole type data, 5m x 5m sample plots used to collect sapling type data, and sample plots The size of 2m x 2m was used to collect data on the type of seedling with a distance between plots of 20m, which was placed along the observation path. Data analysis was carried out using the vegetation analysis method that calculates frequency, density, dominance, relative frequency, relative density, relative dominance, and Important Value Index (INP). The results showed that the composition of tree species in this area consisted of 44 species with a vegetation structure consisting of trees, poles, saplings and seedlings. The highest INP at the seedling level was Suregada sp. by 72.33%; at the sapling level is Suregada sp. by 83.86%; at the pole level is Chyathea contaminans of 79.15%; and at the tree level is Schfflera lucida by 58, 33%.

Abstract

The world is being hit by a new variant of Covid-19, namely Omicron. The Omicron variant is easily dispersed from the previous variant. To prevent transmission of this variant, people need to increase their body's resistance by consuming foods and drinks rich in antioxidants. Moringa leaf tea can be an alternative drink rich in antioxidants to increase endurance and prevent the speed of transmission of the Omicron variant of Covid-19. This study analyzes the presence or absence of secondary metabolites and antioxidant activity in fresh and dry moringa tea. Secondary metabolite compounds were tested using phytochemical screening, which included testing for alkaloids, flavonoids, phenolics, saponins, tannins, steroids, terpenoids, and glycosides, while for antioxidant activity, the DPPH method was used. Based on the test results, the two types of tea did not have antioxidant activity because the IC50 value was more than 250 ppm, namely 868.72 ppm for fresh moringa tea and 2851.67 ppm for dry moringa tea. However, when compared between fresh and dry moringa tea, both have an IC50 value of 1:3 ratio, where the IC50 value of fresh moringa tea is three times lower than that of dried moringa tea. In addition, the results of the phytochemical screening of the two types of tea were positive for several secondary metabolites, namely flavonoids, alkaloids, and saponins.

Abstract

The people of Timor Island only know garlic as a kitchen spice. This research provides new knowledge of the benefits of garlic in the health sector, especially as an inhibitor of free radical that can trigger various degenerative diseases. The aims of this research were to identify secondary metabolites contained in the ethanolic extract of garlic (Allium sativum L.) from Timor Island and to determine its effectiveness in inhibiting free radicals. The method used to test secondary metabolites was phytochemical screening using color reagents. Testing the effectiveness of free radical inhibitors from garlic ethanol extract from Timor Island was carried out in 2 stages: 1.) Determination of DPPH maximum wavelength (λ) and 2.) Measurement of antioxidant activity using DPPH method. The results showed that the ethanolic extract of garlic from Timor Island contained secondary metabolites of flavonoids, phenols and terpenoids. It was also very effective in inhibiting free radicals, with the acquisition of IC50 values 50 ppm which was equal to 9.729 ppm. This research gives some information that can be used for the pharmacological ingredients, i.e. as a natural medicine that safe for the body to be consumed by the people of Timor Island. Moreover that also can impact on demand of garlic in the market. This has a very positive impact on improving the economy of garlic farmers on Timor Island.

Abstract

This reseach aimed to determine the proper cassava drying technique to produce suitable flour properties for food product applications. The method used was proximate analysis and calculation of Gross Energy (GE) value. Furthermore, the results of the study were analyzed using the Two Way ANOVA statistical test followed by the real difference test using the Tukey analysis. Results of the analysis showed that there was no significant difference between the two drying techniques (α0.05). To get good quality flour in the application of food products made from Nuabosi cassava flour is to use oven drying and sun drying techniques. The novelty of this study is that there has been no previous research on the quality of Nuabosi cassava flour using oven drying and sun drying techniques. The benefit of this research is to support the government in the food diversification program on foods made from Nuabosi cassava flour, where Nuabosi cassava is one of the leading types of food in Ende district.
