Abstract

The objective of this study is to determine the effect of the Problem Based Learning model assisted by animated videos on science learning outcomes in the topic of the Human Respiratory System among eighth-grade students at SMP Imelda Medan. The population of this research comprised all eighth-grade students at SMP Imelda Medan. The sample classes were selected using random sampling, with two classes chosen as the sample. This study employed a quantitative research method, specifically a quasi-experimental approach with a Pretest-Posttest Nonequivalent Control Group Design. Data collection techniques included pre-research observation, interviews with science teachers of grade VIII, written multiple-choice tests for students, and documentation during the research. Data analysis was conducted using hypothesis testing (one-tailed t-test). These data indicate that the implementation of the Problem Based Learning model assisted by animated videos significantly improves students' learning outcomes of eighth-grade students at SMP Imelda Medan on the topic of the human respiratory system.

Abstract

This research aims to know the difficulty of student learning on the matter of invertebrates in class X SMAfrom cognitive, learning-based indicator, and the factors causing difficulty learning the students of class X SMAfrom the Sub-district Pancur Batu learning Year 2016/2017. The design of the research that is used is thedescriptive quantitative. The population in the research is that all the students of class X SMA. Samples taken in acluster random sampling Pancur Batu namely SMA Negeri 1 Pancur Batu, SMA Anastasia Pancur Batu, and SMARakyat Pancur Batu with the number of students 171 people's Senior in High School students from the sub-districtPancur Batu. Data collection technique that is used is the test the results of student learning on the matter ofinvertebrates and questionnaires with students who have learning difficulties. The results of the study showedthat the percentage of students learning difficulties On cognitive knowledge level (C1) 25.91% percent with thecategory of difficulty is the level of understanding (C2) 29.86% with the category of medium difficulty,implementation levels (C3) 34.91% with the category of difficulty medium, analysis levels (C4) 49.79% percentwith the category of difficulty is very high, evaluation levels (C5) 60.39% with category of difficulty is very highlevel of creation (C6) 49.19% with a very high level of difficulty category. The factors that influence the difficultyof learning the most dominant is the internal factors namely pscyhiatric of 80.83% and the health of 78.61% withthe cause of the difficulties learning, while external factors namely schools of 78.46% and subjects of 65.47% withthe cause of the difficulties learning.Keywords: difficulties learning, cognitive, and invertebrates

Abstract

This study aimed to evaluate the effectiveness of basil leaf extract (Ocimum americanum L.) on body weight and cecal histopathology in native chickens infected with Eimeria tenella. Eimeria tenella is recognized as one of the most pathogenic Eimeria species in poultry and is responsible for coccidiosis characterized by severe cecal lesions, including hemorrhage, necrosis, and inflammatory cell infiltration (Chapman, 2014; Koutny et al., 2021). Basil leaves were selected because they contain phytochemical compounds such as flavonoids, tannins, and essential oils with potential antibacterial, antioxidant, and immunomodulatory activities (Dwivedi et al., 2021; Kadhim & Abbas, 2023). The experiment employed a completely randomized design consisting of five treatment groups: a negative control, a positive control, and three basil extract treatments at concentrations of 0.05%, 0.10%, and 0.20%. Parameters observed included body weight and cecal histopathological changes. The results demonstrated that basil extract administration influenced the cecal condition of infected chickens, with the 0.10% dose producing the most favorable outcomes compared with the other doses. Histopathological examination revealed the presence of oocysts, necrosis, macrophage infiltration, inflammation, and hemorrhage in infected chickens; however, the severity of lesions varied among treatments. These findings indicate that basil leaf extract has potential as a natural supplement to support the health of native chickens
