No full textThis study aims to determine the effect of supplementary feeding of bean sprouts on the microscopic quality of Balinese cattle spermatozoa at the Regional Artificial Insemination Center of West Nusa Tenggara Province. Microscopic semen evaluation includes volume, mass movement, individual movement, motility and concentration. The design used was a complete randomized design (CRD) and data analysis using Anova which was further tested using Duncan. The mass movement of Balinese spermatozoa in P1 and P2 has a percentage value of 67% (+++), which indicates that the spermatozoa move to form large and progressive waves. Individual motion in P2 produces a very progressive motion with the highest percentage of 60%. The results of the analysis of volume, motility and concentration of Balinese spermatozoa showed significantly different results in P2, namely the treatment with the addition of 4 kg of bean sprouts. Based on the results of this study, it shows that there is an effect of supplementary feeding of bean sprouts with the treatment of 4 kg per week on the microscopic quality of Balinese spermatozoa at the Regional Artificial Insemination Center of NTB Province
Examining Potential Teachers\u27 Capabilities for Creative Thinking in Geometry Problems Using Analytical Framework NEA
No full textIn classroom practice, the use of problems that require students to engage both in higher-order thinking and creative reasoning has been recognized as among the most effective strategies for meaningful learning. Within this context, the present study was designed to investigate in depth the types of errors committed by mathematics education students, who are also prospective teachers, in demonstrating their creative thinking abilities when dealing with geometry-related tasks. The analytical framework employed was Newman Error Analysis (NEA), which provides a systematic way to examine mistakes in problem-solving processes. A qualitative approach with a descriptive case study design was selected in order to capture a detailed picture of the phenomena under investigation. The participants consisted of 22 mathematics education students from a university located in Surakarta. Several methods were used to gather data, including direct classroom observation, the administration of diagnostic tests specifically developed to measure mathematical creative thinking, and in-depth interviews. The data analysis followed the model proposed by Miles and Huberman, involving three interrelated steps: data reduction, data display, and the formulation of conclusions. The findings revealed that the most frequent and significant errors occurred during the transformation and encoding stages of problem solving. This study concludes that strengthening prospective teachers’ exposure to non-routine geometry problems and explicitly addressing common error patterns are essential for improving creative mathematical thinking
The Effect of Acetic Acid Solution Application on Duck Eggs Shell Strength and Incubation Duration During the Critical Hatching Period
No full textThis study aimed to investigate the effect of different levels of acetic acid solution application on duck eggs on eggshell strength and hatching time. The materials used in this study were 180 hatching duck eggs (1–7 days old, weighing 65–75 g) from 16–18week old parent ducks. An experimental method with a Completely Randomized Design (CRD) was employed as the research design. The study consisted of three acetic acid treatment groups (P0: 0%, P1: 10%, P2: 20% acetic acid) and 6 replicates, with each experimental unit using 10 eggs. The variables measured in this study were eggshell strength (MPa) and egg hatching time (hours). Eggshell strength and hatching time data were analyzed using analysis of variance (ANOVA) and orthogonal contrast as a post-hoc test. The results showed the mean values of eggshell strength (MPa) for each treatment as follows: P0 (0.233 ± 0.022), P1 (0.125 ± 0.013), and P2 (0.144 ± 0.031); and hatching time (hours): P0 (650.438 ± 9.714), P1 (622.438 ± 5.519), and P2 (635.503 ± 2.182). Analysis of variance revealed a highly significant difference (P<0.01) in both variables due to the acetic acid application. Orthogonal contrast tests showed no significant difference in eggshell strength between treatments P1 and P2, while there was a highly significant difference (P<0.01) in hatching time between P1 and P2. It can be concluded that acetic acid application significantly reduces eggshell strength and accelerates the hatching of duck eggs. The treatment with a 10% acetic acid concentration demonstrated the most optimal effectiveness in accelerating hatching

Local Wisdom Literacy: Promising Context Integration in Algebra Learning
No full textIndonesian students’ mathematical literacy skills, particularly in algebra, are still relatively low, as shown by the results of PISA 2022. A significant contributing factor is the limited relevance of teaching materials to students’ real-life contexts. This study introduces an innovative approach by developing algebra teaching materials based on local wisdom—referred to as local wisdom literacy—as a meaningful context for improving mathematical literacy among seventh-grade junior high school students. The novelty of this study lies in the integration of traditional Timorese cultural practices, such as weaving patterns, local measurement systems, and indigenous numerical reasoning, into formal algebra instruction. Using the ADDIE development model, this Research and Development (R&D) study produced culturally embedded materials that were validated by experts, with validity scores of 85.4% for content and 85% for assessment instruments. The materials were also considered highly practical (96.93% by students, 96% by teachers) and effective, as indicated by a moderate average N-Gain of 0.42 in student learning outcomes. In addition to improving conceptual understanding and mathematical literacy, the developed materials serve as a culturally responsive pedagogical model that is in line with the objectives of the Merdeka Curriculum and supports the preservation of local culture. This study provides a contextual and humanistic alternative in algebra learning, which offers pedagogical value and cultural significanc
Correlation Between Chest Girth, Body Length, and Body Height on Wither Weight of Rote Sheep Ewes
No full textThis study aimed to analyze the relationship between linear body measurements including chest girth (CG), body length (BL), and wither height (WH) and body weight (BW) in Rote sheep ewes across different age groups to determine the most reliable predictor of body weight. The research employed a quantitative method through direct field measurements and weighing. Data collected including vital statistics (CG, BL, WH) and BW from Rote sheep ewes categorized into three age groups (I0, I2, and I4). The data were analyzed statistically using correlation coefficient (r), the coefficient of determination (R²), and bias analysis to evaluate the accuracy of weight estimation. The results revealed that chest girth exhibited the highest correlation with body weight, particularly in the I0 group (r = 0.93; R² = 86.05%), indicating a strong positive relationship and high predictive accuracy. Body length showed a moderate relationship (r = 0.87; R² = 76.11%) in the same group, while wither height demonstrated a relatively weaker correlation (r = 0.73; R² = 53.94%). Across all age groups, the predictive strength of body measurements decreased with increasing age, suggesting that skeletal growth contributes less to body weight variation in mature sheep. In conclusion, chest girth was identified as the most accurate and reliable linear measurement for predicting body weight in Rote sheep ewes, particularly in younger age groups, and can therefore be used as a practical and non-invasive tool for estimating livestock weight
