Abstract

This research aims to determine the effect of blended learning on students’ learning interests and outcomes in musculoskeletal system subjects. The research benefit proved that blended learning could be a practical alternative learning approach during the pandemic. This research was carried out in October 2021. The research design was experimental and used a quantitative approach through pre-tests and post-tests. Sampling data collection employed cluster random sampling technique. The research sample consisted of 21 students from the experimental group and 21 students from the control class. The control class was given a full online learning treatment, and the experimental class was given a blended learning treatment. A hypothesis testing data analysis was performed using the ANCOVA test. Then, online learning was conducted over four meetings and offline learning was conducted in one meeting. The average learning interest in the experimental class was 124.3, and the control class was 117.62, which was categorized as sufficient. The average percentage increase in learning outcome scores in the experimental class was 70.57%, while it was only 60.48% in the control class. Data processing outcomes on learning interest obtained a value of 0.009 with α = 0.05. Meanwhile, values processed on learning outcomes obtained a value of 0.02 with α = 0.05. The increase in students’ interest and learning outcomes was caused by varied learning styles using the blended learning approach. Hence, based on these data, blended learning significantly affected students’ learning interests and outcomes.

Abstract

Teachers still employ irrelevant teaching material related to Islamic values during teaching and learning. They used the lecturing and question-and-answers methods. Thus, researchers developed teaching materials to make students happy and interested. This research entitled Development of Students’ Worksheet (LKPD) Oriented to Islamic Values through Oncoming Material about Human Excretory System in Class VIII of Junior High School/ Islamic Junior High School (SMP/MTs) to know the students’ responses to the work. The research problems were how to develop students’ worksheets (LKPD) oriented to Islamic values through the oncoming material about the human excretory system and how the students’ responses to LKPD that researchers made. This research was a development research that used the 4D research method. Products produced were categorized as valid not revised because of the validation of design to the tune of 78.12%, validation of subject matter experts to the tune of 70%, and subject matter from Islam experts to the tune of 80%. Meanwhile, the responses of 10 students indicated that four students were categorized as “worthy” to the tune of 94.44%, 83.33%, 100%, and 85.18%, while six students were classified as “quite worthy” with each percentage of 61.11%, 70.37%, 79.62%, 75.92%, 68.51%, and 75.92%.

Abstract

The research has been carried out on the effect of variations in the concentration of earring leaves (Acalypha Indica L.) ethanol extract on the acquisition of inhibition zone values for the growth of S. typhi bacteria. In this study, ethanol solvent was used in the maceration and evaporation stages, then the well diffusion method was used to test its antibacterial activity. Each stage was carried out in triplo and 3 repetitions. Phytochemical test on the evaporated extract showed positive test results for flavonoid and tannin metabolite compounds. Concentration variations that used in this study were 5%, 15%, 30%, 50% and 60%, the antibiotic chloramphenicol was also used as a positive control and aquadest as a negative control. Meanwhile, the antibacterial activity test gave the result that the higher the concentration of the earring leaf extract (Acalypha Indica L.), the inhibition zone value also increased with the following successive values: 0mm, 11mm, 14mm, 15mm and 16mm, on the other hand chloramphenicol showed an inhibition zone of 32 mm. The research data were analyzed statistically using the One Way Anova test. Earring leaf extract (Acalypha Indica L.) has a significant effect of 0.000 on S. Typhi bacteria. However, at the smallest concentration, namely 5%, it does not have an inhibition zone diameter of 0 mm with a significant value of 1000. It can be concluded that the antibacterial activity using chloramphenicol is still higher when compared to the antibacterial activity using the ethanol extract of earring leaves (Acalypha Indica L.) in inhibiting growth of S. Typhi bacteria.

Abstract

The Maman Lanang plant ( Cleome rutospermae dc ) is a weed plant that is often found in rice fields or grows on community cultivated plants which are usually used as food for people on the outskirts. This research aims to determine the effect of the extract concentration of the Maman Lanang Plant ( Cleome rutospermae dc ) on the inhibition zone for the growth of Staphylococcus aureus and Escherichia coli bacteria, as well as to find out how much the concentration of the extract from the Maman Lanang Plant ( Cleome rutospermae dc ) is close to the inhibitory zone value of the positive control of tetracycline in inhibiting the growth of Staphylococcus aureus and Escherichia coli bacteria . This research is a laboratory experimental study using a Completely Randomized Design (CRD) using the hole/cup diffusion method with four varying concentrations, namely 10%, 30%, 60% and 90%, and the positive controls used are tetracycline and distilled water as a negative control. The main ingredient used in this research was the Maman Lanang plant ( Cleome rutospermae dc ) which was extracted using the maceration method for three days with 96% ethanol solvent, after that the extract obtained was then subjected to an evaporator to obtain the crude extract then carried out a phytochemical test and after that The antibacterial activity of the crude extract from the Maman Lanang Plant ( Cleome rutospermae dc ) was tested against the bacteria Staphylococcus aureus and Escherichia coli .
