Diwana Ulfi, Nurkhairo Hidayati — Thu, 01 May 2025 00:00:00 +0000

This study aims to conduct a needs analysis on the importance of Pop-up Book learning media for class IX Science-Biology subjects at SMPN 25 Pekanbaru. This type of research is quantitative descriptive research. The instrument used is a questionnaire consisting of 3 indicators: the learning process, the use of learning media and the use of Pop-up Books. The sample used in this study was students in grades IX 4 and IX 5, totalling 70 students. The results showed that overall the average percentage of the needs analysis for developing Pop Up Book learning media was 79.12% in the excellent category. The highest response was found in the indicator of the use of learning media, with a percentage of 93.92% in the very good category, and the lowest response was found in the Pop-up Book usage indicator, with a percentage of 52.49% in the sufficient category. Based on the results of this study shows that no Pop-up Book learning media is available at SMPN 25 Pekanbaru. Therefore it is necessary to develop Pop Up Book learning media for class IX Science-Biology subjects at SMPN 25 Pekanbaru to make it easier for students to understand the material and foster students' learning motivation.

This study aims to (1) describe the effect of implementing based learning devices Green Education on the understanding of junior high school students' concepts in Sumbawa Regency and (2) describe differences in understanding the concepts of junior high school students in Sumbawa Regency through implementation based learning tools Green Education. This type of research is a pre-experimental design with a plan One Group Pretest-Posttest Design. The study population was all junior high school students in Sumbawa Regency, with the sample being class VII students at SMPN 1 Lenangguar and SMPN 4 SATAP Lenangguar. The research instrument uses tests to measure students' understanding of concepts and data analysis techniques using inferential statistics, namely analysis N-gain and free sample t-test. The research results show that; (1) there is the influence of learning-based devices green education to understanding the concept of SMPN 1 Lenangguar students and students of SMPN 4 SATAP Lenangguar with N-gain respectively 0.4 and 0.5 in the medium category, and (2) there is no difference in students' understanding of concepts in the two experimental schools (p = 0.354 > 0.05).

Ali Wafa, Linda Tri Antika — Thu, 01 May 2025 00:00:00 +0000

The 21st-century education is known as the age of knowledge (knowledge age), characterized by an accelerated increase in knowledge. The demand for mastery of various skills is also one of the characteristics of education today. One of the skills in the spotlight is life skills. The research objective was to determine the effect of guided inquiry on students' life skills. This research is quantitative, like an experimental design, nonequivalent pretest-posttest control group. The subjects of this study were students of class X IPA B and X IPA C MA Miftahul Ulum Bettet Pamekasan Madura in the even semester of 2021/2022. The academic life skills (thinking skills) rubric is used to obtain life skills data through a written test in the form of an essay. This study's results indicate no effect of guided inquiry on students' life skills. Life skills still need to be empowered students in learning to support student learning outcomes and the future. The guided inquiry remains a recommended learning model to empower life skills. Researchers need to consider students' readiness for research, especially study habits, and teachers or researchers should master the learning model used before conducting research.

This study aims to examine the effect of cigarette smoke on the weight of the mice's ovaries (Mouse muscle). The study used an experimental approach, with experimental female mice strains Balb/c species Mouse muscle aged 2-3 months totalling 24 pregnant tails. Mice were treated with cigarette smoke using an injection where the tip was cut so that there was a hole where the cigarette was burned once a day every morning or evening for 13 days. The treatment used three doses, namely P0 (0 cigarettes), P1 (1 cigarette), and P2 (2 cigarettes). Ovarian organ harvesting was carried out on the 13th day, followed by weighing the ovaries. The data obtained were then analyzed using One Way ANOVA. The results showed that (a) exposure to cigarette smoke did not have a significant effect on the weight of the mice's ovaries (Mouse muscle) during pregnancy, and (b) exposure to cigarette smoke significantly affects the number of follicles in the ovaries.

The Effect of Cigarette Smoke Exposure to The Number of Implantation Points in Pregnancy Mice (Mouse muscle)

Implantation is the process by which the blastocyst sinks into the endometrium after the release of the Zona Pellucida. This study aims to examine the effect of cigarette smoke on the number of implantation points in pregnant mice (Mouse muscle). This study used a completely randomized design (CRD), with strained female mice as experimental animals Bal b/c species Mouse muscle two months old, totalling 24 tails. Treatment was given on day 1 of pregnancy with control treatment (P0), one cigarette (P1), and two cigarettes (P2). Surgery was performed on the 13th day to calculate the number of implantation points. Data were analyzed using One-Way ANOVA. The results showed the treatment's effect on the number of mice pregnancy implantation points (p < .05). Treatment P0 had the highest point of implantation, followed by treatments P1 and P2. These results indicate that cigarette smoke can inhibit the process of cell division, inhibit the formation and development of blastocysts, and further process pre-implantation and implantation in mice.
