Oestrous Behavior of Cows Induced by Different Hormones
No full textProstaglandin and estrogen hormones are two types of hormones commonly used in heat synchronization aimed at inducing earlier estrus in livestock. This study aims to determine the success rate of artificial insemination (AI) in beef cattle synchronized in heat with different hormones. The research method used is a Completely Randomized Design (CRD) consisting of 3 treatments and 4 replications: P0 (natural estrus), P1 (prostaglandin injection), and P2 (estrogen injection). The parameters tested in this study include the percentage of estrus, intensity of estrus and time of estrus symptoms. The analysis used is Analysis of Variance (ANOVA). The results indicate that the percentage of cattle showing signs of estrus in all three treatments reached 100%. The intensity of estrus in each treatment was assessed in three categories: clear estrus (score 3+++), moderate estrus (score 2++), and low estrus (score 1+). The results showed that in P0 and P2, 50% of the cattle exhibited clear estrus and 50% moderate estrus, while in P1, 66.7% showed clear estrus and 33.3% moderate estrus. The onset of estrus symptoms in P0 occurred on average at hour <480 or days 18-20 from the first to the second estrus cycle, whereas in P1 and P2, it appeared at hour 48 or day 2 after injection

ABSTRACT
This research aims to know whether or not using quantum writing is effective to improve the mastery of XI grade students of SMA FQI Kefamenanu in writing English, identify the part of writing which is still difficult for the students to master writing English, and categorize their level of mastery in writing English. To get the data, they taught twice and give the students test and questionnaire. The results of data analysis show that the students’ average score is 65 in pretest while 95 in posttest. In indicates that they had problems in writing competence. Their dominant problem is that they did not have enough vocabulary to write in English. However, quantum writing method has helped them to write. Therefore, although their level of mastery was just enough in pretest, their level of mastery was excellent in posttest. The method has effectively improved their writing competence. These findings require all teachers of English promote quantum writing as the appropriate method that can help the students to write well in English.

Model Pendidikan Matematika Realistik sebagai Upaya Peningkatan Literasi Numerasi Siswa
No full textThe purpose of this study is to analyze the effectiveness of the Realistic Mathematics Education (RME) approach in improving students’ numeracy skills through a systematic literature review. Fifteen articles published from 2018 to 2024 were reviewed, with inclusion criteria centered on studies investigating the implementation of RME in mathematics instruction aimed at enhancing numeracy competence. The results of the analysis showed that the application of RME was most often carried out at the elementary school level with 7 articles, followed by junior high school level with 6 articles, and senior high school/vocational school with 2 articles. The materials used in the implementation of RME varied, including whole numbers, number operations, geometry, geometric shapes, trigonometry and systems of linear equations in two variables (SPLDV). In terms of methods, 8 articles used a quantitative approach, 6 articles used classroom action research (CAR), and 1 article was descriptive. In general, all studies showed that RME contributed positively to improving students\u27 numeracy, both in aspects of conceptual understanding, problem-solving skills, and mathematical representation. However, research limitations are evident in the limited number of studies at the high school/vocational school level and the limited longitudinal research. Therefore, further research is needed to expand the scope to higher education levels and use standardized numeracy evaluation instruments to more comprehensively understand the effectiveness of PMR
Efektivitas Pengembangan Media Pembelajaran Berbasis Website dengan Model Kooperatif tipe Numbered Head Together (NHT) terhadap Pemahaman Konsep Himpunan Siswa
No full textThe problem addressed in this study is that many students have not yet mastered basic mathematical concepts, particularly sets. This research aims to analyze the effectiveness of developing website-based learning media with the Numbered Head Together (NHT) cooperative learning model in enhancing seventh-grade students\u27 understanding of set concepts at MTs Puspa Bangsa. The research methodology employed a quantitative approach using quasi-experimental research with a pretest-posttest control group design involving 60 students divided into experimental and control groups. The research instruments consisted of validated tests for understanding set concepts, student response questionnaires, and learning activity observation sheets. The research findings indicate a significant difference in set concept understanding between students who used NHT learning media compared to those who received conventional instruction (discussion and lecture methods). The experimental group\u27s mean posttest score was 83.44, while the control group scored 66.56. The T-test analysis revealed an F value of 2.186 with a significance level of 0.143, and a calculated t-value of 8.254, which exceeded the table t-value of 1.999, resulting in a significance value of 0.000 < 0.05. Therefore, this study demonstrates that the effectiveness of developing website-based learning media with the NHT cooperative learning model makes a positive contribution to seventh-grade students\u27 understanding of set concepts at MTs Puspa Bangsa and can be recommended as an effective alternative strategy for mathematics instruction
