Abstract

This study aims to determine the influence of the Novick constructivism learning model on 1) critical thinking skills and motivation, 2) the extent of influence of the Novick constructivism model on the aspects of critical thinking skills, 3) the extent of influence of the Novick constructivism model on learning motivation, and 4) the effectiveness of the model on critical thinking skills. The method used was quasi-experimental with a non-equivalent pretest-posttest control group design. The population was the tenth-grade science students. The critical thinking skills were assessed using a cognitive test, and the motivation was assessed using questionnaires. The MANOVA analysis was used to determine the model's influence. The regression analysis was used to determine the extent of the model's influence. The N-gain was used to determine the model's effectiveness. The MANOVA analysis obtained a significant value of 0.02, which was lower than 0. 05. Thus, H0 was rejected. The regression analysis showed the values of critical thinking skills ranged from high to low. The values consisted of strategies and tactics (46.49%), advance clarification (14.02%), basic support (13.96%), elementary clarification (13.62), and inference (11.88%). The motivation aspects ranging from high to low: relevance (26.35%), attention (25.98%), confidence (25.40%), and satisfaction (22.25%). The N-Gain score obtained by the experimental class was 0.437 in the moderate category. Based on the results, it can be concluded that 1) there was an influence of Novick constructivism model on critical thinking skills and motivation on online learning, 2) there was an unequal influence of the model on critical thinking aspects, and 3 ) motivation aspects, and 4) Novick constructivism model was relatively effective to be used in online learning.

Abstract

This study aimed to determine the effect of Catharanthus roseus leaves extract on kidney histology of mice aspartame-induced. Mice were divided into 4 groups, namely the negative control group (K-) without treatment, the positive control (K+) given aspartame 0.02 mg/day, the dose group 1 (D1) was given aspartame 0.02 mg/day and continued with the C. roseus leaves extract at a dose of 0.42 mg/kg. Group 2 (D2) was given aspartame 0.02 mg/day followed by C. roseus leaf extract at a dose of 0.84 mg/kg BW. IP administered aspartame for 14 days, and C. roseus leaves extract was administered by gavage for 12 days. The data obtained were analyzed by One Way ANOVA and DMRT test with a significance level of 0.05. The results showed that the induction of aspartame at a dose of 0.02 mg/day in mice increased the average number of proximal tubular necrosis cells. Catharanthus roseus leaves extract administration at 0.42 mg/kg BW and 0.84 mg/kg BW for 12 days can reduce the number of proximal tubular necrosis cells in aspartame-induced mice. Thus it can be concluded that the administration of C. roseus leaves extract can reduce the proximal kidney tubules necrosis but has not been able to reach normal conditions yet.

Abstract

This research employed the experimental method with descriptive data analysis. It aimed to isolate and identify sponge symbiont bacteria with antibacterial potential against Multi-Drug Resistance Organisms (MDRO) with the 16S rRNA gene marker. Based on the study results, two sponges were obtained, namely Clathrina sp and Agelas sp, each having 11 and 7 isolates of symbiont bacteria, respectively. Based on the antibacterial activity test results, out of 18 isolates of symbiont bacteria, only 4 had antibacterial potential against MDRO (Klebsiella pneumoniae ESBL, Pseudomonas aeruginosa ESBL, or Staphylococcus lugdunensis MRSA) with inhibition zones of 9.3 mm, 8.3 mm, and 8.1 mm, respectively. The results of bacterial identification using the 16S rRNA gene sequence isolate S1I3, S1I9, and A1I3 belong to the Bacillus cereus and Bacillus paramycoides types. This research is expected to provide important information about sponge symbiont bacteria with antibacterial potential against MDRO.
