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).

Judul: Correlation Between Stress Level, Sleep Quality, and Food Habits with Nutritional Status in IPB University Dormitory Students
Abstrak: Penelitian ini bertujuan mengetahui dan menganalisis hubungan tingkat stres, kualitas tidur, dan kebiasaan makan dengan status gizi pada mahasiswa asrama IPB. Desain penelitian ini merupakan studi cross sectional dengan jumlah subjek sebanyak 78 mahasiswa asrama IPB University. Penelitian dilakukan secara langsung pada bulan Mei 2024 melalui pengisian kuesioner dan wawancara. Instrumen pengukuran tingkat stres menggunakan kuesioner PSS-10, kualitas tidur menggunakan kuesioner Pittsburgh Sleep Quality Index (PSQI), kebiasaan makan menggunakan kuesioner Adolescent Food Habits Checklist (AFHC), status gizi diukur secara langsung pada berat badan dan tinggi badan. Sebagian besar subjek mengalami stres sedang (72%), kualitas tidur yang buruk (85%), dan kebiasaan makan yang tidak sehat (65%). Sebagian besar status gizi subjek tergolong normal (61%). Hasil analisis menunjukkan tidak terdapat hubungan signifikan antara tingkat stres, kualitas tidur, dan kebiasaan makan dengan status gizi (p>0,05)., This research aims to determine and analyze the correlation between stress level, sleep quality, and food habits with nutritional status in IPB University dormitory students. The design of this research was a cross-sectional study with 78 IPB University dormitory students as subjects. The research was conducted online in May 2024 by filling out questionnaires and interviews. Instruments for measuring stress levels using the PSS-10, sleep quality using the Pittsburgh Sleep Quality Index (PSQI) questionnaire, food habits using the Adolescent Food Habits Checklist (AFHC) questionnaire, nutritional status was measured directly on body weight and height. Most subjects experienced moderate stress (72%), poor sleep quality (85%), and unhealthy food habits (65%). Most of the subjects nutritional status was classified as normal (61%). The results of the analysis showed that there was no significant correlation between stress level, sleep quality, and food habits with nutritional status (p>0.05).

Judul: Sintesis Nano Hidroksiapatit Berbasis Cangkang Telur Bebek Berbantukan Iradiasi Gelombang Mikro
Abstrak: Iradiasi gelombang mikro telah digunakan untuk membantu sintesis nano hidroksiapatit. Kalsium sebagai prekursor untuk sintesis nano hidroksiapatit diperoleh melalui kalsinasi cangkang telur bebek, sedangkan H3PO4 digunakan sebagai sumber fosfor. Hidroksiapatit disintesis dengan variasi daya dan waktu iradiasi gelombang mikro. Sampel yang diperoleh dikarakterisasi dengan XRD, FTIR, SEM, dan EDS. Kalsinasi pada 1000 oC menunjukkan bahwa data tersebut sesuai dengan pola XRD CaO dan komposisi kalsium tertinggi adalah 65.46%. Gugus fungsi yang muncul pada spektra FTIR diantaranya, OH-, PO4 3-, dan CO3 2-. Sampel yang diiradiasi pada daya tinggi 400 W dan waktu 45 menit menunjukkan ukuran kristalit dan partikel kecil. Citra SEM menunjukkan bahwa nano hidroksiapatit memiliki morfologi berbentuk oval. Karakterisasi EDS menunjukkan bahwa hanya oksigen, fosfor, dan kalsium yang terdeteksi. Rasio molaritas Ca/P sampel adalah 1.68 hampir mendekati rasio hidroksiapatit sebesar 1.67.
