Abstract

The purpose of this study was to analyze the hematology and histopathology of the gills of carp (C. carpio) treated with active compounds of red betel leaf extract (P. crocatum). This research method used a completely randomized design (CRD). The treatments used in this study were doses of 75 mg/L, 150 mg/L, 225 mg/L, 300 mg/L, 375 mg/L, negative control (healthy fish), and positive control (positive control), (healthy fish), and positive control (chloramphenicol antibiotic). Results of hematology and histopathology studies the results of hematology and histopathology studies on the gills of carp (C. carpio) after being infected with A. hydropilla bacteria experienced stress, this can be seen from. decreased red blood cells, increased leukocytes, and damage to the gill tissue. Carp returned to normal after being treated with red betel leaf extract. The best dose obtained after treatment was a dose of 300 mg/L. The results of clinical symptom observations showed a change from abnormal to normal conditions in goldfish after being treated. The conclusion is that red betel leaf extract contains dominant compounds in the form of flavonoids and alkaloids which can be useful as a medicine for goldfish infected with A. hydropilla bacteria.

Abstract

The purpose of this research is to develop Nearpod-based learning media to help improve students’ low learning outcomes and maximize the use of technology-based media at SDN Wonosari 02 Semarang City. This research is a type of Research and Development (R&D) research with the ADDIE development model. The results showed that Nearpod-based learning media is very feasible to use in learning IPAS human respiratory system material with a percentage of assessment by material experts of 88.75% and media experts of 93.75%. The results of the questionnaire assessment by teachers related to the media obtained a percentage score of 90% and students of 93.33% with a very feasible category. For the Paired Sample T-Test test with a significance value of sig. (2-tailed) obtained a result of 0.000. So, it is known that the value is < 0.05. Therefore, it can be concluded that there is a significant difference from the average pretest score and the average posttest score. As for the N-Gain Test, the score shows an average of 0.71 with high criteria. The conclusion of this study is that Nearpod media is feasible and effective to improve student learning outcomes in IPAS learning.

Abstract

Today’s learning process utilizes technological-based interactive learning media that improve students’ understanding of chemistry. Animaker is one of the AI-powered platforms to create animation and live-action videos. Therefore, this research tried to utilize Animaker to produce interactive learning media on atomic structure material, analyze the quality of the media based on material and media experts, as well as teachers, and determine students’ responses to the media. ADDIE model of research and development was used as the guideline in producing the media. First, needs analysis was carried out through literature reviews and preliminary studies. Second, the initial design was proposed, consisting of opening, main, and closing. Third, the design was then developed using Animaker website. In this stage, the media draft was validated by material and media experts. Two experts said that the media was excellent, although they provided feedback to improve the media. Some revisions were made before the media was delivered to teachers for quality testing. All teachers agreed that the media is of excellent quality (96.36%). The final media was then handed over to the student participants and they provided positive responses to the media. The Animaker is suitable for creating media that is interactive, interesting, and fun.

Abstract

Cerebral palsy (CP) is a non-progressive motor disorder caused by prenatal, perinatal, and postnatal factors, leading to movement and posture abnormalities. In Indonesia, around 0.60% of the total child population has CP (9 cases per 1000 live births). Speech and swallowing difficulties are common, affecting children’s nutritional status and development. Speech and oral motor therapy are effective in improving speaking and oromotor dysfunction. To determine the effectiveness of oromotor and speech therapy in improving swallowing, chewing, and speech abilities in children with CP. A case study was conducted at the "Lombok Care" Children with Disabilities Foundation. Language development was assessed with the Messay Language Test, and oromotor dysfunction was evaluated using Debra C. Gangale’s method. Pre and post-therapy assessments were performed to assess changes in motor and speech functions. The evaluation of 5 respondents showed an increase in speaking skills after speech therapy and swallowing skills after oromotor therapy. Both are shown to be effective in improving communication skills and oropharyngeal muscle coordination, as well as reducing the risk of aspiration. Speech and oral motor therapy are essential and effective in improving eating, swallowing, and speaking abilities in children with CP, and are an important part of holistic medical rehabilitation.

Abstract

This research aims to develop flipbook media based on augmented reality using ecosystem material. Research and Development (R&D) is the research method used, while ADDIE is a development model consisting of analysis, design, development, implementation, and evaluation. Tests and non-tests are used for data collecting, while qualitative and quantitative methods are employed for data processing. The study's participants comprised 22 fifth-grade pupils and an educator from SDN Sidomulyo 3. The outcomes demonstrated how extremely possible it is to use Flipbook media with augmented reality for education. Media, material, and language expert validation scored 90, 94, and 92%. The normality test results indicate that the data is normally distributed, with the Sig. The pretest value was 0.74 > 0.05, and the Sig. Postest value of 0.14 > 0.05. A paired sample t-test showing the impact of employing Augmented Reality-based Flipbook media in learning, with a Sig. (2-tailed) 0.00 < 0.05. The n-gain test shows 0.78 with a high category. In light of these findings, it may be said that augmented reality-based Flipbook media is feasible and effective for learning IPAS Ecosystem content in grade V elementary school.
