Abstract

The Calotes genus presents a challenge due to the complexity of its species. However, research on the cryptic species complex within the Indonesian Calotes genus is still lacking. This study aims to determine the extent of genetic relationships and assess the potential existence of a species complex within the Indonesian genus Calotes (Daudin, 1802) (Squamata, Agamidae) using the partial Cytochrome c Oxidase Subunit 1 (COI) gene sequence as a molecular marker. Samples of the Indonesian Calotes genus in this study were collected from South Lampung (Lampung), Bogor (West Java), and Langkat (North Sumatra). By aligning 582 bp sequence similarities with reference sequences in GenBank, we confirmed that seven out of eight samples analyzed belonged to Calotes vultuosus, while one sample was identified as Calotes versicolor. The identity values ranged from 96 to 100%. The C. vultuosus samples in this study displayed lower genetic distances, ranging from 0 to 3%, with the reference C. vultuosus sequence from Indonesia compared to the reference sequence from India, which ranged from 6 to 9%. Phylogenetic tree reconstruction, utilizing both maximum likelihood with IQ-Tree and Bayesian Inference with BEAST methods, further supports these findings. It reveals distinct groupings between C. vultuosus samples from Indonesia and India. These results suggest the potential occurrence of a species complex within the Indonesian genus Calotes. Furthermore, the inclusion of eight COI gene sequences from two Calotes species in the GenBank database has the potential to confirm the existence of previously undocumented species in Indonesia.

Abstract

Pollinator insects are insects that help the pollination process in plants by transferring pollen to other plants. The pollen attaches to the hairs and legs of the insect at the time when the pollinator's insect is foraging. This study aimed to analyze the diversity index and dominance index of pollinator insects in the Kebun Raya Institut Teknologi Sumatera. This research was conducted at the Kebun Raya Institut Teknologi Sumatera, specifically the orchard (guava and dragon fruit) and aesthetic garden. This study used purposive sampling by taking data directly at the observation site. Data analysis was used to calculate the diversity of pollinator insects within the ecosystem. The analysis involved calculating the diversity index (H') and dominance index (D). The study shows that pollinator insects come from 5 orders: Coleoptera, Diptera, Hemiptera, Hymenoptera, and Lepidoptera. Each observation location in the Kebun Raya Institut Teknologi Sumatera has a moderate category diversity index: guava orchards 1.93, dragon fruit orchards 1.53, and aesthetic gardens 1.60. The dominance index of each observation site showed values with low categories, namely guava orchards at 0.18, dragon fruit orchards at 0.32, and aesthetic gardens at 0.28. Visiting activities in the morning are dominated by the family Apidae, while daytime and afternoon are dominated by the family Nymphalidae. High temperatures lead to decreased activity of pollinator insects.

Abstract

This study aims to identify the types of plants consumed by Sumatran elephants, the parts they eat, and the most frequently consumed plant species as a basis for managing Sumatran elephant feed in the Camp Elephant Response Unit (ERU) area of Bukit Barisan Selatan National Park. Data was collected through direct observation from 09:00 to 15:00 WIB, with observation locations determined using the purposive sampling method. The collected data included the types of food plants, the parts consumed, and the most frequently eaten plant species. Data analysis was conducted by calculating the Sorensen species similarity index and the foraging frequency. A total of 30 plant species were identified as elephant food, with 19 species found in open land habitats. The highest plant species similarity index based on habitat type was found on mixed habitats with swamp openings and cover, reaching 63.15%. The highest plant species similarity index based on individual elephants was recorded for Haryono and Renold at 80%. Eight plant species were identified as the most frequently consumed, including Brachiaria mutica, Cyperus kyllingia, Fimbristylis sp., Imperata cylindrica, Paspalum conjugatum, Panicum repens, Rynchospora corymbosa, and Scleria sp. Additionally, elephants only foraged eight plant species for other functions. Based on this study, Sumatran elephant only consume plant species that are abundant within their grazing habitat. The findings of this study can support the ex-situ conservation of Sumatran elephant by ensuring the continued availability of their food plants in the Camp ERU area of Bukit Barisan Selatan National Park.

Abstract

Tidur adalah salah satu kebutuhan dasar manusia yang termasuk dalam kebutuhan fisiologis. Kualitas tidur merujuk pada kondisi yang dialami seseorang untuk mencapai kesegaran dan kebugaran setelah bangun tidur. Terdapat dua fase dalam tidur, yaitu fase Rapid Eye Movement (REM) dan fase Non Rapid Eye Movement (Non REM). Pada fase tidur Non REM, terjadi penurunan norepinefrin yang diduga berperan dalam meningkatkan kreativitas tertentu. Penelitian ini bertujuan untuk menginvestigasi variasi kualitas tidur dan kreativitas pada mahasiswa Institut Teknologi Sumatera (ITERA). Penelitian dilakukan dengan wawancara menggunakan kuesioner yang meliputi pendataan demografi, Pittsburgh Sleep Quality Index (PSQI) untuk menentukan kualitas tidur, dan Adjective Check List (ACL) untuk menentukan sifat kreativitas responden. Hasil penelitian menunjukkan bahwa kualitas tidur mayoritas mahasiswa ITERA cenderung buruk. Selain itu, juga terdapat temuan bahwa mahasiswa ITERA umumnya memiliki sifat yang mengarah tidak kreatif. Namun, menariknya, ditemukan bahwa mahasiswa ITERA dengan kualitas tidur yang buruk justru lebih banyak memiliki sifat kreatif.

Abstract

Fluid intelligence is the ability to think quickl and flexibly in solving new problems without relying on past experiences. Meanwhile, self-control is the ability to carry out necessary tasks and resist unwanted and unnecessary temptations. Students, as individuals transitioning into adulthood, may have unique self-control and fluid intelligence due to ongoing brain development. This study aims to analyze the relationship between fluid intelligence and self-control among students at Sumatra Institute of Technology. The research method used in this study involved interviews using the Baddeley Reasoning Test and self-control Scale with 161 respondents, consisting of 73 males and 88 females. The results of the study indicate that there was no significant relationship between fluid intelligence and self-control. One factor that may explain higher fluid intelligence in males is that they are often required to make decisions. Additionally, higher self-control in females may be attributed to societal expectations of more normative behavior for women.

Abstract

Sexual selection occurs when living organisms, including humans, exhibit specific preferences for morphological traits related to health and fertility when choosing a mate. Various physical characteristics such as body size and shape, leg length, skin color, hair length and color, facial features, and breast size contribute to the physical attractiveness of females in mate selection. Breasts can serve as a particular attraction for males, as they are believed to be associated with health and fertility for reproductive purposes. Sexual selection leads to a range of breast sizes, from small to large, within a population. The aim of this research is to investigate the variation in breast size preferences among females in the Indonesian society, specifically in Lampung. The study was conducted by distributing both online and offline questionnaires randomly with breast size stimuli in the form of images. Descriptive data analysis was employed to examine the variation in breast size preferences. Very large breast sizes were considered healthy and feminine by respondents, while medium sizes were deemed attractive. Married male respondents preferred larger breast sizes on average compared to unmarried respondents. Higher-income respondents tended to select larger breast sizes. Respondents with lower educational backgrounds tended to prefer smaller breast sizes. Respondents residing in rural areas preferred larger breast sizes compared to those living in urban areas. In conclusion, sexual selection applied among the population of Lampung in the context of breast size preferences.

Abstract

Macaca fascicularis is a diurnal primate that lives in social groups. In Taman Nasional Way Kambas, particularly in the Elephant Training Center area, long-tailed macaques are frequently observed interacting with tourists, and such interactions through ecotourism activities are suspected to influence their natural behavior. Therefore, research on their daily behavioral patterns is essential as part of conservation efforts. Observations were conducted using the scan sampling method over a 30-day period during morning (06:00–10:00 WIB) and afternoon (16:00–18:00 WIB) hours at 5-minute intervals. The results indicate that feeding was the predominant daily behavior (42%), whereas mating was the least frequently observed (2%). Overall, Macaca fascicularis in the Elephant Training Center area of Taman Nasional Way Kambas still maintain their natural behaviors but have begun to show adaptations to human presence that may potentially alter their long-term activity patterns. Perilaku Harian Monyet Ekor Panjang (Macaca fascicularis) Di Kawasan Pusat Latihan Gajah Taman Nasional Way Kambas ABSTRAK: Macaca fascicularis merupakan primata diurnal yang hidup dalam kelompok sosial. Di Taman Nasional Way Kambas, khususnya di kawasan Elephant Training Center, monyet ekor panjang sering diamati berinteraksi dengan wisatawan, dan interaksi tersebut melalui aktivitas ekowisata diduga dapat memengaruhi perilaku alaminya. Oleh karena itu, penelitian mengenai pola perilaku harian monyet ekor panjang menjadi penting sebagai bagian dari upaya konservasi. Pengamatan dilakukan menggunakan metode scan sampling selama 30 hari pada waktu pagi (06.00–10.00 WIB) dan sore hari (16.00–18.00 WIB) dengan interval pengamatan setiap 5 menit. Hasil penelitian menunjukkan bahwa perilaku makan merupakan aktivitas harian yang paling dominan (42%), sedangkan perilaku kawin merupakan yang paling jarang diamati (2%). Secara keseluruhan, Macaca fascicularis di kawasan Elephant Training Center Taman Nasional Way Kambas masih mempertahankan perilaku alaminya, namun mulai menunjukkan adaptasi terhadap keberadaan manusia yang berpotensi memengaruhi pola aktivitas jangka panjangnya.
