Abstract

ABSTRAKPenelitian ini membahas kemampuan Tetraselmis chuii dalam menyerap karbon dioksida di berbagai intensitas cahaya (4000, 5000, dan 6000 lux) dengan konsentrasi CO2 tetap sebesar 3% volume. Dengan memanfaatkan jenis mikroalga tersebut, penyerapan CO2 dapat berlangsung karena kemampuan mikroalga berfotosintesis sama besarnya dengan tumbuhan darat. Proses fotosintensis berlangsung di dalam bubble fotobioreaktor dengan kapasitas 1 liter (200 ml T. chuii, 800 ml air laut, dan pupuk Conwy 1 ml) dan laju alir gas total sebesar 1 liter/menit. Analisis penyerapan CO2 dilakukan dengan cara menggelembungkan CO2 ke larutan Ca(OH)2 1 M. Hasil penelitian menunjukkan bahwa penyerapan CO2 rata-rata paling tinggi adalah kondisi intensitas cahaya 6000 lux. Naik turunnya data penelitian menunjukkan adanya peristiwa photo-inhibition.

Abstract

Introduction: Obstructive sleep apnea (OSA) is a significant pediatric health concern in Indonesia, but diagnostic and treatment pathways are often resource-constrained. Drug-induced sleep endoscopy (DISE) offers a dynamic assessment of upper airway obstruction, but its predictive value for treatment outcomes in Indonesian children remains unclear. This study aimed to evaluate the predictive value of DISE findings for polysomnography (PSG)-determined OSA severity and surgical outcomes in a multicenter cohort of Indonesian children. Methods: A prospective, multicenter cohort study was conducted at three tertiary hospitals in Indonesia. Children aged 2-18 years with suspected OSA underwent DISE and overnight PSG. DISE findings were classified using the VOTE (Velum, Oropharynx, Tongue base, Epiglottis) classification system. The primary outcome was the correlation between DISE findings and the apnea-hypopnea index (AHI) on PSG. Secondary outcomes included the prediction of surgical success (defined as a postoperative AHI < 5 and >50% reduction from baseline) after adenotonsillectomy (T&A). Statistical analyses included Spearman's rank correlation, receiver operating characteristic (ROC) curve analysis, and logistic regression. Results: 250 children (mean age 8.2 ± 3.5 years, 60% male) were included. A significant positive correlation was found between the total VOTE score and AHI (ρ = 0.62, p < 0.001). Tongue base obstruction (VOTE-T) showed the strongest correlation with AHI (ρ = 0.58, p < 0.001). The area under the ROC curve (AUC) for the total VOTE score predicting severe OSA (AHI ≥ 10) was 0.85 (95% CI, 0.79-0.91). In the subgroup of 180 children who underwent T&A, a higher total VOTE score (particularly VOTE-T and VOTE-E scores) was significantly associated with a lower likelihood of surgical success (OR 0.45, 95% CI 0.28-0.72, p = 0.001). Conclusion: DISE, using the VOTE classification, demonstrates good predictive value for OSA severity and surgical outcomes in Indonesian children. Tongue base and epiglottic obstruction are particularly important predictors. DISE can be a valuable tool for guiding treatment decisions in resource-limited settings.

Abstract

This research evaluates the sustainability of the culinary cafe business through business suitability analysis. This research aims to assess whether culinary cafes have adequate business suitability to achieve long-term sustainability. The business suitability analysis method is used to identify factors that influence the success and sustainability of a culinary cafe business. Primary and secondary data were analyzed to support this evaluation. The research findings highlight the importance of factors such as location, target market, competition, and environmental policies in determining the sustainability of a culinary cafe business. The practical implications of this research can help business owners and entrepreneurs to make better decisions in managing and developing a culinary cafe business in a sustainable manner.
