Abstract

Fermentasi Bacillus subtilis menggunakan nira siwalan (Borassus flabellifer L.) sebagai sumber karbon telah dilakukan untuk mengevaluasi aktivitas antibakterinya terhadap Staphylococcus aureus. Penelitian ini merupakan true experimental dengan rancangan post-test only control group design. Kelompok perlakuan diberi nira siwalan pada konsentrasi 10%, 20%, dan 30%, sedangkan kelompok kontrol negatif menggunakan aquadest steril. Aktivitas antibakteri diuji dengan metode difusi cakram, dan data dianalisis menggunakan uji One Way ANOVA diikuti uji Dunnett T3. Hasil penelitian menunjukkan bahwa produk fermentasi menghasilkan zona hambat dengan diameter berkisar 18,87–22,29 mm pada seluruh konsentrasi perlakuan, yang secara signifikan berbeda dari kontrol negatif (p = 0,000). Disimpulkan bahwa nira siwalan dapat dimanfaatkan sebagai media fermentasi Bacillus subtilis untuk menghasilkan senyawa antibakteri.

Abstract

Tension-Type Headache (TTH) is the most common headache and is often stress-related. Engineering students face high academic burdens that may trigger insomnia and affect pain thresholds. Despite neuroanatomical links between sleep and pain, evidence regarding the insomnia-TTH relationship in this group remains inconsistent. Objective: To determine the relationship between insomnia and TTH among engineering students at the Faculty of Science and Engineering, Universitas Nusa Cendana. This analytic observational study used a cross-sectional design. Stratified random sampling selected 52 active students from the cohorts of 2022, 2023, and 2024. Instruments included the Headache Screening Questionnaire (HSQ) and Insomnia Severity Index (ISI). Data were analyzed using the Spearman correlation test. The prevalence of insomnia among respondents was predominantly categorized as subthreshold insomnia (42.3%) and moderate clinical insomnia (42.3%). The prevalence of TTH was also high, with 65.4% of respondents experiencing TTH and 23.1% experiencing probable TTH. Bivariate analysis results indicated no significant relationship between insomnia and Tension-Type Headache ($p=0.667$; $r= -0.061$). The very weak negative correlation indicates that an increase in insomnia scores was not statistically associated with an increase in TTH incidence. Insomnia and TTH prevalence are high among engineering students, but no significant relationship was found between insomnia and TTH in this population.

Abstract

Language development is a crucial aspect of a child’s growth and development. A child’s language development can be influenced by the duration of screen time, particularly during the “golden age” of 2–5 years. This study aims to determine whether there is a relationship between screen time duration and language development in children aged 2–5 years. This study was conducted in the service areas of the Sikumana Community Health Center and the Tarus Community Health Center with a sample size of 60 participants using a sequential sampling method. The research method employed was quantitative with a cross-sectional design. Based on the results of the chi-square test, a p-value of 0.02 was obtained, indicating that there is a relationship between screen time duration and language development in children aged 2–5 years.

Abstract

ABSTRACT The increasing use of smartphones among adolescents has the potential to lead to addiction, which may affect their ability to cope with social situations and trigger social anxiety. In Kupang City, smartphones serve as the primary medium for adolescents to communicate and access entertainment, resulting in high usage intensity. This condition highlights the need to examine the relationship between smartphone addiction and social anxiety among adolescents in this setting.  This study sought to examine the relationship between smartphone addiction levels and social anxiety levels among students of SMP Negeri 1 Kupang in 2025. This quantitative observational analytic study with a cross-sectional design was conducted at SMP Negeri 1 Kupang. A total of 88 students from grades VIII and IX were selected using cluster sampling. Smartphone addiction was evaluated using the Smartphone Addiction Scale–Short Version (SAS-SV), whereas social anxiety was measured with Liebowitz Social Anxiety Scale–Self Report (LSAS-SR The relationship between variables was examined using Spearman’s rank correlation test at a 5% significance level (p 0.05). Smartphone addiction was predominantly in the moderate category (53.4%), while social anxiety was most frequently classified as mild (22.7%). Spearman’s rank correlation test showed a positive association of moderate strength between smartphone addiction and social anxiety (r = 0.512; p 0.001). There is a significant relationship between smartphone addiction and social anxiety among students of SMP Negeri 1 Kupang in 2025.  Keywords: Smartphone Addiction, Social Anxiety, Adolescents, Kupang City.  ABSTRAK Meningkatnya penggunaan smartphone pada remaja berpotensi menimbulkan adiksi yang dapat memengaruhi kemampuan mereka menghadapi situasi sosial, termasuk memicu kecemasan sosial.
