This study aimed to analyze the bioactive compounds of Caulerpa recemosa, Sargassum sp., and Gracillaria verrucosa from Makssar Strait using three different solvents i.e. acetone, ethanol , and methanol. Samples of the seaweed C. recemosa collected from marine waters of Takalar regency, while Sargassum sp. and G. verrucosa were collected from marine waters of Pangkep regency which is part of the Makassar Strait. Seaweed crude extract qualitatively analyzed using Thin Layer Chromatography (TLC). The treatment applied in this studi is Sargassum sp. with acetone solvent, Sargassum sp. with ethanol solvent, Sargassum sp. with methanol solvent, C. recemosa with acetone solvent, C. recemosa with ethanol solvent, C. recemosa with methanol solvent, G. verrucosa with acetone solvent, G. verrucosa with ethanol solvent, and G. verrucosa with methanol solvent. Parameters measure were the total extract yield, total phenolic content and phytochemical compound of seaweed crude extrac. The result showed that the content of bioactive compounds crude extract of seaweed is affected by the species of seaweed and solvents used in extraction process. The crude extract of C. recemosa produces better bioactive compounds than the crude extract of G. verrucosa and Sargassum sp. as shown by the yield and total phenolic content of crude extract. The best solvent used in extracting bioactive compounds of C. recemosa is methanol. Identified phytochemical compounds from the crude extract of C. recemosa, are flavonoids, terpenoids, alkaloids, and phenols.
Paper bertujuan memaparkan pendidikan dan tantangan pembelajaran berbasis teknologi informasi di Era Revoulusi Industri 4.0 dan kesiapan indoensia menjawab tantangan pendidikan era revolusi industri 4.0 dalam membangun system pembelajaran berbasis teknologi informasi.

Kebijakan manajemen pendidikan di Indonesia saat ini mendorong seluruh level pendidikan, terutama pendidikan tinggi untuk memanfaatkan kemajuan teknologi digital dan komputasi pendidikan era revolusi industry keempat. Beberapa solusi yang bisa dilakukan antara lain, kesesuaian kurikulum dan kebijakan dalam pendidikan, kesiapan SDM dalam memanfaatkan ICT, mengoptimalkan kemampuan peserta didik, dan mengembangkan nilai - nilai (karakter) peserta didik, serta dan kesiapan sarana dan prasarana pembelajaran berbasis digital. Key words: Pendidikan, Pembelajaran Bervasis Teknologi Informasi, Revolusi Industri 4.0
This study aims to describe the effect of Teaching Game for Understanding (TGfU) in increasing the students’ motivation and physical fitness. TGfU is a training concept of sport based on game. It is not only have meaning as strengthening educational praxis in fields of sport-game separately, but rather to develop an educational approach to the problems solving in tactical strategy in a competition of the sport-game, and also about attitude, motivation, responsibility for the task, collaboration, etc. Method of this study uses a qualitative approach with classroom action research. The results of the study reported that method of TGfU can increase students’ motivation and physical fitness especially in the second cycle of teaching and learning in the field. For sport teacher is advised to use this model in order to improve students’ participation, motivation, tactical cognitive and strategy and sport achievement of their physical fitness, especially for the subject matter of sport required the game approach.
The incidence of leptospirosis is caused by Leptospira bacteria. No data on the results of examination and research on risk factors of leptospirosis occurrences in the area. The study aims to determine the magnitude and risk factors of leptospirosis existed in flood-prone areas at Wajo District. The research type was analytical with cross-sectional and analysed by chi-square and Principal Component Analysis (PCA). The sample was 273 people selected through proportional random sampling and examination of serum sample by the enzyme-linked immunosorbent assay (ELISA). The research found Leptospirosis incidence was 130 people (47.6%). Socio-demographic societal conditions referred to occupation and rat urine patches associated significantly with leptospirosis (p=<0.05). PCA test that showed the distribution of risk factors based on clusters on F1, F2 and F3 discovered that the observational axes F1 and F2 was 63.36% and F1 and F3 was 55.93%. This research suggested Wajo Health Department to increase socialization of prevention and diagnosis to societies with Leptospirosis symptom/suspect and those in a flood-prone area which specific to hygiene and sanitation events.
In recent years, interest in exploring the effectiveness of different cooperative learning models in promoting science learning outcomes for high school students has been increasing. The three most studied models are STAD (Student Teams Achievement Divisions), TGT (Teams-Games-Tournaments), and TTW (Think-Talk-Write). The purpose of this study was to compare the effectiveness of the STAD, TGT, and TTW models on science learning outcomes of class VII students in junior high school. The research method was an experimental study with a comparative design. The results showed a significant difference in science learning outcomes among students taught using the three cooperative learning models. The TGT and TTW models did not show a significant difference in learning outcomes, although the TGT model showed better learning outcomes than the STAD and TTW models. This study also highlights the importance of considering specific learning objectives and student characteristics when selecting and adapting cooperative learning models. While the TTW and TGT models can be effective alternatives to the STAD model in improving science learning outcomes for junior high school students, further research is needed to explore the long-term effectiveness and generalizability of these models in different contexts
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
