Judul: The Relationship between Fluid Intelligence and Sleep Quality among Undergraduate Students in Indonesia
Abstrak: Fluid intelligence is the ability to solve problems through concept creation, inductive and deductive reasoning, and classification without prior knowledge. Previous research found that fluid intelligence correlates with sleep quality in humans. However, these studies were generally only conducted in one region, and social and demographic factors were minimally discussed. This study aims to examine the relationship between fluid intelligence and sleep quality in undergraduate students in Indonesia. Data were collected through a questionnaire completed by 411 undergraduate students across Indonesia. The Baddeley Reasoning Test (BRT) was used to measure the fluid intelligence level of the respondents, and the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality. Data were analyzed with R Studio software. The correlation between fluid intelligence and sleep quality was analyzed with the Spearman correlation test. This study shows that university students in Indonesia have high levels of fluid intelligence and poor sleep quality (8,59±2,85). Fluid intelligence and sleep quality do not have a significant relationship (R = -0.037, p-value = 0.45).

Judul: Teknostres dan Kualitas Tidur pada Mahasiswa di Indonesia
Abstrak: This study aimed to examine the prevalence of technostress and sleep quality by considering sociodemographic variables and a high number of participants. This study also examined the relationship between technostress and sleep quality among university students in Indonesia. A total of 1,356 Indonesian universities participated in this cross-sectional survey. The Technostress Creator Questionnaire (TSC-Q) and the Pittsburgh Sleep Quality Index (PSQI) were used, and the results were analyzed using Spearman’s correlation test. The generalized linear model (GLM) determined which sociodemographic factors predicted technostress levels and sleep quality. The respondents reported moderate levels of technostress (3.12 ± 0.53 out of 5.00) and poor sleep quality (7.9 ± 2.83). Lower academic level, a lower monthly allowance, a longer duration of device ownership, a more significant number of devices, and long screen times were associated with higher technostress levels. The Science and Technology students experienced lower technostress than the Social and Humanities students. A lower monthly allowance and longer screen time were associated with poor sleep quality. Higher levels of technostress were significantly associated with poorer sleep quality (p < 0.05).

Tumbuhan dari famili Bombacaceae merupakan jenis sumber pakan kelelawar lalai yang paling banyak ditemukan, yakni mencapai 10,7%. Kesamaan jenis tumbuhan sumber pakan tertinggi adalah pada Macroglossus sobrinus dengan Eonycteris spelaea, yakni dengan indeks kesamaan Morisita sebesar 0,70. Kelelawar lalai memanfaatkan sumber pakan yang berbeda, baik antar spesies maupun antar jenis kelamin. Kesamaan pemanfaatan jenis sumber pakan antar jantan dengan betina tertinggi terjadi pada Macroglossus sobrinus jantan dan Eonycteris spelaea betina, yakni sebesar 0,713. Jenis-jenis kelelawar lalai pemakan polen dan nektar adalah Macroglossus sobrinus, Eonycteris spelaea, dan Rousettus amplexicaudatus; sedangkan pemakan buah adalah Cynopterus minutus, Cynopterus brachyotis, Cynopterus sphinx, dan Cynopterus titthaheileus. Jenis-jenis tumbuhan yang dimakan oleh kalong Pteropus vampyrus di Kebun Raya Bogor adalah Inga sp. dan Euphorbiaceae sp. (Euphorbiaceae), Sonneratia sp. (Lythraceae), Durio oblongus (Bombacaceae), Anacardiaceae sp. (Anacardiaceae), serta jenis palem Palmae sp.
