Background: Habitat is a place for living things to grow and develop. Differences in habitat in an area can affect the size of an organism. This study aims to determine the morphometric variations of Tetragonula laeviceps found in urban and forest habitats in Central Sulawesi Province. Methods: This research was conducted with roaming technique. Morphometric characters observed were 35 characters of stingless bee and analyzed using Microsoft Excel software. Results: The results of this study indicated that the morphometric size variation of T. laeviceps found in forest habitats (3.58 mm) is greater than that of wild bee in urban habitats (3.05 mm). Conclusions: Different habitat characteristics can affect the morphometry variations of the bee, especially in T. laeviceps species. The bee's morphometry body size is greater than in the forest habitat, because in that habitat there are environmental temperatures and types of plant sources of nectar which are more supportive for bee life compared to urban habitats.

NT3 protein is expressed by Neurotrophin 3 (NTF-3) which plays a role in the process of differentiation, survival of peripheral and neuropathological of neurons. The information of structure and function of NT-3 proteins is still very limited, especially in Gallus gallus. This study aims to predict the three-dimensional structure of the Trk A and Trk B proteins in Gallus gallus. The target protein obtained from the UniProt server with access codes Q91009 (Trk A) and Q91987 (Trk B) using the 6kzc 1.A (PDB ID) template was analyzed in silico through a homology approach and describing the structural assessment using Chimera UCSF software. The analysis showed that the Trk A protein had a QMEAN value of -0.08, composed of 778 amino acids, mass 87334.30 Daltons, and Seq Identity 79.93%. Trk B had a QMEAN value of 0.16, consisting of 818 amino acids, mass 91732.05 Daltons, and Seq Identity 84.30%. Key words: NT3; homology; UCSF chimera; G. gallus

Background: Protein struktural VP1 berperan sebagai pemain kunci dalam patogenesis, memiliki keunikan yang cukup menarik untuk dikaji dengan mempelajari sifat dan fungsi protein struktural VP1. Penelitian ini bertujuan untuk memprediksi struktur tiga dimensi protein VP1 pada EV-A71. Metode: Protein target diperoleh dari server UniProt dengan kode akses A0A097EV89 menggunakan template 4cey.1.A (PDB ID) dianalisis secara in silico melalui metode homologi menggunakan server SWISS-MODEL. Hasil: analisis penelitian menunjukkan protein target dan template memiliki identity 95,29 % dan tersusun dari 297 asam amino dengan nilai QMEAN -2,15. Protein struktural VP1 pada Ramachandran Plots memiliki struktur stabil, residu non-glisin pada daerah outlier hanya berkisar 0,34 % (A53 ALA) dengan Nilai rotamer outliers 1,61 %. Kesimpulan: Model struktur tiga dimensi protein yang diteliti memiliki struktur stabil dan informasi yang didapatkan berguna untuk penelitian lebih lanjut dalam pengembangan vaksin penyakit yang disebabkan oleh EV-A71.

Information on foraging activity is important for efforts to increase the productivity of Apis cerana honeybees. Honey bees flying activities are carried out in the context of nest guarding activities from enemy attacks, removing feces from the nest, and foraging which takes place during the day to collect pollen and nectar from plants. This study aims to analyze the daily activity patterns of bees A. cerana which is influenced by environmental factors. This study used two colonies of A. cerana, namely colony one and colony two with the same colony size. The observed behaviors were bees leaving the nest, entering with pollen, and entering without pollen. The number of A. cerana colony one flying for pollen was high in the morning and low in the afternoon due to the very high light intensity during the day. Unlike colony one, A. cerana colony two did not actively perform flight activities and showed a different activity of flying in front of the nest forming a crowd in the afternoon. An inflorescence calendar needs to be developed to determine the flowering period of plants around the hive so that bee forage is continuously available to avoid absconding. absconding. Identification of plant pollen as a source of bee food needs to be done to determine the types of plants utilized by bees.

Xylocopa latipes Drury are one species of bee found in the Hymenoptera order, in the family Anthophoridae. Carpenter bees, which are essential for plant pollination, build their nests in decaying wood and bark. Carpenter bees visit the bean crop to collect pollen and nectar for their hives. This study aims to determine the visit of the wood bee X. latipes on long bean plants in Central Sulawesi. The study employed a descriptive survey methodology that involved field sampling at bean planting and direct observation of X. latipes in the field. measured the temperature and the light intensity. The findings revealed that X. latipes visits to the bean crop at Desa Nambaru, Kecamatan Parigi Selatan, Kabupaten Parigi Moutong average 58,3 people each visit. The morning at 08.30 am averages 21 X. latipes visits; the afternoon at 15.30 pm averages 9 Xylocopa latipe visits; and the afternoon at 11.30 am averages 2 Xylocopa latipe visits. The amount of light present during X. latipes visit to the bean crop has a significant impact. Weather variables like temperature, humidity, and wind speed had an impact on the multivariate regression's very real relationship to X. latipes visit to bean planting.

Low metacognitive abilities and high-level thinking cause students to have difficulty understanding genetics course material. This research aims to analyze the effectiveness of PBLRQA, PBL, and RQA strategies on students' metacognitive and higher-order thinking skills. This research uses a non-equivalent control group pretest-posttest design. Sampling was carried out on 118 students consisting of four classes using saturated sampling techniques. The research instruments used were observation sheets on lecturer and student activities, essay-based metacognitive skills tests, and multiple-choice tests on high-level thinking skills. Lecturer and student activity data were analyzed based on the percentage of indicators categorized as high and very high syntactically. Data on metacognitive skills and higher-order thinking were analyzed using the Normalized Gain and Independent Kruskal Wallis tests. Research findings show that implementing PBLRQA, PBL, and RQA strategies is ineffective in improving students' metacognitive and higher-order thinking skills. To follow up on these findings, further research is needed to explore the involvement of learning styles and social support on students' metacognitive skills and higher-order thinking skills, focusing on implementing PBLRQA and RQA strategies.
