Abstract

Salah satu pakan alami yang paling baik dalam budidaya perikanan adalah D. magna yang sudah banyak dibudidayakan dan dapat diambil langsung dari alam, namun belum cukup dalam memenuhi kebutuhan. Untuk itu penelitian ini bertujuan untuk mengetahui pengaruh pertumbuhan populasi dan kualitas warna dari D. magna berdasarkan lama aerasi sehingga dapat mengetahui lama aerasi yang paling optimal untuk kultur D. magna. Penelitian ini dilaksanakan dengan membuat tiga faktor perlakuan dan satu faktor kontrol. Faktor kontrol adalah tanpa aerasi, faktor A dengan aerasi 3 jam/hari, faktor B dengan aerasi 6 jam/hari, dan faktor C dengan 24 jam aerasi. Masing – masing faktor memiliki 3 kali pengulangan. Hasil penelitian menunjukkan bahwa lama waktu aerasi 3 jam/hari adalah faktor paling optimal dalam menunjang pertumbuhan populasi D. magna dan faktor kontrol yaitu tanpa pemberian aerasi paling optimal dalam menunjang warna D. magna. Hasil analisis data dalam uji Friedman menunjukkan adanya perbedaan pengaruh pada pertumbuhan D. magna. Hasil pengukuran kualitas air menunjukan kadar DO cenderung turun bahkan melewati batas minimum, namun pada faktor C kadar DO masih dalam kadar optimal. Suhu berkisar 24.1 – 30.6 ℃ dan pH berkisar 6.3 – 7.0. Kondisi ini masih dalam kisaran optimum untuk kultur D. magna.  One of the best natural feeds in aquaculture is D. magna which has been widely cultivated and can be taken directly from nature, but is not sufficient to meet the needs. For this reason, this study aims to determine the effect of population growth and color quality of D. magna based on aeration time so that can determine the most optimal aeration time for D. magna culture. This research was conducted by making three treatment factors and one control factor. The control factor was without aeration, factor A with aeration 3 hours/day, factor B with aeration 6 hours/day, and factor C with 24 hours aeration respectively. Each factor has 3 repetitions. The results showed that aeration time of 3 hours/day was the most optimal factor in supporting the growth of D. magna population and the control factor without aeration was the most optimal in supporting the color of D. magna. The results of data analysis in the Friedman test showed there were different effect on the growth of D. magna. The results of water quality measurements show that DO levels tend to fall even past the minimum limit, but in factor C, DO levels are still in optimal levels. The measurement of temperature ranges from 24.1 – 30.6 and the pH ranges from 6.3 – 7.0. This condition was still in the optimum range for D. magna culture

Abstract

This study aims to analyze students' science process skills through online assessments using the Rasch model analysis. The method used is quantitative through the analysis of the Rasch model. The data was collected using an online assessment with a test technique based on basic science process skills. The results showed that as many as 21 students (43.75%) had a KPS above or equal to the class average KPS and 12 students (25%) had high abilities in all aspects of basic KPS. In addition, as many as 27 students (56.25%) still have abilities below the class average and 15 (31.25%) still have abilities below the average test difficulty level. However, it can also be seen that 33 other students (68.75%) have a KPS ability above the average level of test difficulty. In conclusion, some basic process skills that need to be improved in students are observing, measuring, communicating and predicting skills.

Abstract

Medicinal plants are natural sources of effective antimicrobials from natural products. Tithonia diversifolia (Asteraceae) is a conventional herb that can be used for the treatment of malaria, wounds, and other diseases with biological properties such as antioxidant, antimalarial, antidiabetic, antibacterial, and anti-hyperglycemic. Research on Tithonia diversifolia leaf extract as an antibacterial has been widely carried out. However, its use as a natural antibacterial is rarely studied, especially on flowers and roots. This study aimed to test the antibacterial activity of leaf, flower, and root extracts of the Tithonia diversifolia plant in various solvent fractions. The methods used in this research were Antibacterial Testing with Agar Diffusion and Direct Bioautography Methods, while the solvent fractions used were petroleum ether, chloroform, and ethyl acetate. The results showed that the crude extract of Tithonia diversifolia leaves, flowers, and roots for petroleum ether, chloroform, and ethyl acetate fractions contained antibacterial compounds. They could inhibit the growth of E. coli, P. aeruginosa, S. aureus, and B. subtilis bacteria, with inhibitory activity in chloroform fraction, which was better than in petroleum ether and ethyl acetate fractions. The results of the bioautography test showed that the inhibition was good on gram-positive bacteria with the highest number of spots in the chloroform fraction for the crude leaf and flower extract samples.

Abstract

COVID-19 has a low fatality rate but has developed into a pandemic due to its highly infectious nature. Nonetheless, COVID-19 fatality is increasing in patients with a history of comorbidities. Based on survey, it was concluded that the understanding of the residents of RT 02 RW 08 Dusun Rogomulyo, Semarang Regency regarding the comorbid COVID-19 was still lacking. In addition, there was the limited funds as problem among residents to carry out medical check-up regularly. Therefore, it was necessary to increase the understanding and detection of the comorbid COVID-19 presence in these community groups. This Community Service consists of four stages of activities, including survey, health education, free medical check -up, and data analysis. The free medical check-up produced the existing comorbid COVID-19 information in this community group as its activity output, namely cardiovascular disease, especially hypertension (51.1%) and cholesterol (20%). This information supports socialization activities and was able to foster understanding and awareness of citizens to better maintain their health conditions, especially related to the comorbidity of COVID-19.

Abstract

Interview results showed that teachers still experience difficulties in carrying out educational action research, especially in developing instruments for collecting data and analize the results. Community Service in collaboration with 35 teachers who are members of the Biology Teacher Association (MGMP) of Semarang District as partners was carried out as an effort to resolve these problems. Community Service was carried out through three stages, namely preparation, training, and evaluation. The main stage of this program was carried out in the form of training using the lecture and discussion methods which are presented in three parts. The results of the questionnaire analysis at the end of the program showed that on average the majority of answers were agreed (as much as 60.7%) to various statements indicating an increase in partners' understanding and skills regarding educational action research. Therefore, it was concluded that the PkM program implemented succeeded in increasing partners' knowledge of the basic concepts of educational action research  preparation. The training provided has also improved the skills of teachers in carrying out and writing scientific papers resulting from educational action research.

Abstract

Lake Rawa Pening is one of the natural resources with abundant local potential that can be utilized in the world of education and the surrounding community. The objectives of this study are: a) to determine the local potential of Lake Rawa Pening, and b) to determine the level of knowledge of junior high school students about Lake Rawa Pening related to local potential of the Lake in relation to science learning materials. The subjects of the study were grade IX junior high school students in eight schools around Lake Rawa Pening. Interviews and tests were used fordata collection technique. Data analysis were carried out by calculating students' scores and interpreting them into the minimum completion criteria (KKM) category by the Ministry of Education and Culture.  Based on the results of the study, it is known that there are twenty-four types of fish, one type of lobster, one type of shellfish, five types of birds, twenty types of plants, and two types of inanimate objects that are included in the local potential of Lake Rawa Pening. Based on the results of the study, the average value of junior high school students' knowledge about the local potential of Lake Rawa Pening in relation to science learning materials only reaches 63, which it is categorized as insufficient. It was found that students' knowledge in insufficient category is 77%, the sufficient category is 19%, the good category is 4%, and no students were found to have knowledge in the very good category.
