Objective of this research was to determine the effectiveness of various culture mediums on thecleavage to morula in in vitro embryo culture of ovine. A total of 1.064 zygotes (fertilized oocytes) were grown in three kinds of different embryo culture medium, which were Tissue Culture Medium 199 (TCM-199) (T1), TCM-199 + 17â-estradiol (T2) and TCM-199 + co-culture of Fallopian Tube Epithelial Cell (FTEC) (T3). Data were analyzed using a completely randomized design with ANOVA analysis and HonestlySignificant Difference test. The variable observed were the percentage of embryo cleavage and morula. Results showed that T3 had the highest percentage (72.45%) of the cleavage occurred in zygotes cultured in the TCM-199 + FTEC co-culture medium, as well as embryo growth to the morula stage (75.75%). Incontrast, zygotes cultured in T1 and T2 had lower cleavage and lower morula development than T3, as much as 27.38%; 47.82% and 58.15%; 66.66%, respectively. In conclusion, TCM-199 + FTEC co-culture medium is the best medium for embryo culture.

The purpose of this study was to examine performances and factors that influence the gestation length (GL) and litter size (LS) of New Zealand White Grade (NZW Grade) rabbits. Reproduction records of NZW Grade rabbits were taken from April 2020 to March 2021. Data analysis was carried out using the general linear model (GLM) procedure from Statistical Analysis System (SAS) University Edition V.6p.2. software. Farm showed a significant effect (P<0.001) on LS and significant season (P<0.05) on GL and LS. GL in the rainy season (31.56) was shorter than the GL in the summer (32.26), but the LS in the rainy season (7.06) was greater than the LS in the rainy season (6.37). Maintenance management should be improved to reduce the impact of the season on GL and LS NZW Grade rabbits.

Simpo and Limpo cattle is a crossbred cattle of Indonesian local cattle and exotic cattle that popular among traditional farmers in Indonesia. The objective of this study was to identify genetic diversity of Simpo and Limpo cattle based on blood-protein polymorphism. A total of 70 blood samples were collected from unrelated 35 heads of Simpo cattle and 35 heads of Limpo cattle from Grobogan dan Kendal population. The blood plasm was used to identify the blood proteins. Blood protein analysis was performed using Sodium Dodecyl Sulfate-Polyacrilamide Gel Electrophoresis (SDS-PAGE). Observed bands were used to perform allele interpretation of five locus, namely Pre-albumin (Pe-Alb), Albumin (Alb), Post-albumin (Po-Alb), Ceruloplasmin (Cp) and Amylase-1 (Am-1). Results showed there were polymorphism in all of the five blood protein locus in both cattle; 4 of 5 and 2 of 5 of the blood-protein locus studied showed deviation from Hardy-Weimberg Equilibrium (HWE) for Simpo and Limpo cattle, respectively and the average heterozygosity value (H) was 0.478 and 0.362 for Simpo and Limpo cattle, respectively. In conclusion, the study indicated that population of Simpo and Limpo cattle has high genetic diversity. Keywords: allele frequency; genotype frequency; heterozygosity

Molecular genetic markers are regularly implemented in rabbit management for better breeding by selecting for specific genotypes. This study aimed to examine the diversity of the melanocortin-4 receptor gene in rabbits in Central Java, Indonesia. A total of 35 bucks were used in this study, comprising 10 New Zealand White, 11 Hyla and 14 Hycole. The DNA was extracted by Gene JET Whole Blood Genomic DNA extraction kit. Single Nucleotide Polymorphism (SNP) was detected by Polymerase Chain Reaction (PCR) and DNA sequencing. Hot carcass weight, cold carcass weight, reference weight and cut point 1-5 weight were among the parameters that were measured. This study showed that Melanocortin 4 Receptor (MC4R) genes were polymorphic, containing missense mutations and one SNP at 519G→A SNP 519GA had two alleles, A and G, with three genotypes (AA, GG, and AG). The rabbit population did not achieve HardyWeinberg Equilibrium (HWE) and showed a low level of genetic diversity as indicated by the heterozygosity results. The result of this study concluded that the frecuency AG as a genotype was higher than either GG or AA and A had a higher allele frequency than G. We recommended improving the validity of the data across various rabbit populations

This study aimed to evaluate the growth performance of Red-Combed Kedu (RCK), Black-Combed Kedu (BCK), and White Kedu (WK) chickens based on sex during the early growth phase (0 to 10 weeks of age). A total of 136 Kedu chickens were raised under uniform management conditions, consisting of 99 RCK (65 roosters and 34 hens), 29 BCK (5 roosters and 24 hens), and 8 WK (6 roosters and two hens). Body weight was recorded weekly and analysed using a two-way General Linear Model (GLM) in SAS to assess the effects of chicken variety, sex, and their interaction. The Shapiro–Wilk test confirmed that the data were normally distributed (p > 0.05). The results showed that sex had a significant effect on body weight from weeks 3 to 10 (p < 0.05), with roosters consistently exhibiting higher weights than hens. Significant differences among chicken varieties were observed only in the hen group at weeks 9 and 10, where BCK hens had higher body weights (p < 0.05) than WK hens, while RCK hens showed intermediate values. In contrast, no significant differences were found among rooster groups at any age. These findings suggest that genetic factors play an essential role in influencing growth performance in Kedu chickens, particularly in hens. This information provides a valuable foundation for breeding selection and the conservation of local chicken genetic resources.

This research aims to analyze the development and implementation of PjBL in higher education through bibliometric analysis. Using data from Publish or Perish and Watase UAKE for the 2019-2023 period, this analysis identifies publication trends, dominant research themes, and the most influential authors and institutions in PjBL research. Using the Systematic Literature Review (SLR) method, 114 relevant article publications were found in the Publish or Perish and Watase UAKE databases, with 25 documents from the period 2019 to 2023 selected and analyzed based on the inclusion criteria. The literature review process was carried out in accordance with PRISMA guidelines to ensure the quality of results and data analysis using VOSviewer software version 1.6.20. The research results show a significant decline in the publication of PjBL articles in the tertiary context, and there was the highest peak of publications in 2020. Most of the publications came from Spain, Indonesia and the United States, and the approaches most frequently used were quantitative and qualitative methods. Themes explored include the impact, role and implementation of PjBL. Density mapping analysis shows that knowledge about project-based learning has not been explored in depth, so further research is needed to expand understanding regarding the implementation of PjBL in the higher education context. ABSTRAKPenelitian ini bertujuan untuk menganalisis perkembangan dan implementasi PjBL di perguruan tinggi melalui analisis bibliometrik. Dengan menggunakan data dari Publish or Perish dan Watase UAKE selama periode 2019-2023, analisis ini mengidentifikasi tren publikasi, tema penelitian yang dominan, serta penulis dan institusi paling berpengaruh dalam penelitian PjBL. Dengan menggunakan metode Systematic Literature Review (SLR), 114 publikasi artikel yang relevan ditemukan di database Publish or Perish dan Watase UAKE, dengan 25 dokumen dari periode 2019 hingga 2023 yang dipilih dan dianalisis berdasarkan kriteria inklusi. Proses peninjauan literatur dilakukan sesuai dengan pedoman PRISMA untuk menjamin kualitas hasil dan analisis data menggunakan bantuan perangkat lunak VOSviewer versi 1.6.20. Hasil penelitian menunjukkan penurunan yang signifkan dalam publikasi artikel PjBL di konteks perguruan tinggi, dan terjadi puncak publikasi tertinggi pada tahun 2020. Sebagian besar publikasi berasal dari Spanyol, Indonesia, dan Amerika Serikat, dan pendekatan yang paling sering digunakan adalah metode kuantitatif dan kualitatif. Tema yang dieksplorasi termasuk dampak, peran, dan penerapan PjBL. Analisis pemetaan densitas menunjukkan bahwa pengetahuan tentang pembelajaran berbasis proyek belum banyak dieksplorasi secara mendalam, sehingga diperlukan penelitian lebih lanjut untuk memperluas pemahaman terkait penerapan PjBL di konteks perguruan tinggi.
