Abstract

This study aims to describe the variation in haplotype distribution and phylogenetic relationships of the Philippine scrub fowl based on the EEF2 gene. Eggshell samples were obtained from Tolitoli and Luwuk, Central Sulawesi. DNA isolation followed the gSYNCTM Extraction Kit protocol, and the amplification process was carried out in 38 cycles, including the pre-denaturation stage (95°C, 5 minutes), denaturation stage (95°C, 45 seconds), annealing stage (53°C, 40 seconds), elongation stage (72°C, 1 minute), and post-elongation stage (72°C, 10 minutes), followed by sequencing. Sequence editing was performed using GeneStudio, sequence alignment and phylogenetic tree reconstruction using MEGA 11, and haplotype network reconstruction using DnaSP and PopART. The results showed that the haplotype network based on the EEF2 gene formed three haplotypes, with the population from Tolitoli having a widespread haplotype, while the population from Luwuk had a specific haplotype. In addition, based on the results of phylogenetic tree reconstruction, it was found that the Philippine white-eye birds from Tolitoli and Luwuk were in the same clade but there was genetic variation between populations.

Abstract

This study aims to determine the effect of the use of video-based learning media on student learning outcomes in Biology class X at SMA Negeri 5 Palu. The background of this study is based on the low student learning outcomes caused by the use of learning media that are still predominantly conventional, such as lectures and textbooks. The study used a quantitative approach with a quasi-experimental method with a Nonequivalent Control Group Design. The research subjects consisted of 66 students, divided into an experimental class (X M1, 33 students) with video-based learning treatment, and a control class (X M2, 33 students) with conventional methods. The research instruments included a questionnaire to determine student responses and learning outcome  tests in the form of pre-tests and post-tests. Data analysis was carried out through validity tests, reliability tests, swimmer tests, and non-parametric tests (Wilcoxon Signed Rank Test and Mann-Whitney U Test) with the help of SPSS. The results showed that both the experimental and control groups experienced an increase in learning outcomes from pre-test to post-test, but the experimental group obtained a higher average score with a significant difference (p < 0.001). The questionnaire reliability test produced a Cronbach's Alpha value of 0.826 which is included in the very reliable category. The Mann-Whitney test showed a mean rank of the experimental group of 50.00, higher than the control of 17.00. Thus, it can be concluded that the use of video-based learning media has a significant effect and is more effective than conventional methods in improving students' understanding of Virus material in Biology subjects.

Abstract

This study aims to simply identify Bacillus thuringiensis isolates from oil palm plantation soil in Batubara Regency through Coomassie Brilliant Blue (CBB) staining. Soil samples were isolated using a serial dilution method and then grown on selective media. The colonies formed were observed based on the morphological characteristics of Bt. The results of this study indicate that several isolates have morphological characteristics that match the characteristics of Bacillus thuringiensis. CBB staining successfully detected the presence of crystalline proteins in several isolates, characterized by the formation of crystals and the ability to bind blue dye in cells that have undergone sporulation, indicating the presence of delta-endotoxin. This study confirms that oil palm plantation soil in Batubara Regency has the potential as a source of local Bt isolates. The Bt isolates found can be used as initial candidates in the development of biopesticides while supporting environmentally friendly and sustainable pest control strategies.
