Abstract

The development of essential oil extraction techniques has seen significant advancements with the introduction of Ultrasound-Assisted Extraction (UAE) technology. UAE is known for its ability to accelerate chemical processes and improve the efficiency of essential oil extraction. However, to achieve optimal extraction quality and yield, precise control over various process parameters is required. This study focuses on enhancing the UAE extraction process by integrating modified features, including a temperature sensor, speed sensor, frequency regulator, temperature controller, stirrer, and cooler, into the extraction apparatus. Objective of this research is to develop a UAE-based extraction apparatus with advanced features that optimize the pre-treatment extraction process of essential oils. The research employs a Research and Development (R&D) approach to design and develop the UAE-based extraction apparatus. The apparatus is then tested to evaluate its performance in optimizing the extraction process. Experimental trials are conducted to assess the impact of each feature on the efficiency and quality of the extracted essential oils. The integration of the temperature sensor, speed sensor, frequency regulator, temperature controller, stirrer, and cooler allowed for better control over the extraction conditions, leading to higher yield and improved quality of the essential oils. The apparatus demonstrated its ability to consistently produce essential oils with higher purity and active ingredient concentrations compared to conventional methods. In conclusion, the development of the modified UAE-based extraction apparatus proves to be an effective solution for optimizing the essential oil extraction process

Abstract

Background: Overweight and obesity are increasing globally and in Indonesia, particularly among pre-seniors and seniors. Age-related changes and behavioral factors heighten obesity risk. Data from the 2023 Indonesian Health Survey (SKI) show a high burden of obesity among older adults in Central Java. Objective: To identify determinants of overweight and obesity risk factors among pre-seniors and seniors in Central Java based on the 2023 SKI data. Methods: A cross-sectional study using secondary data from 23,602 respondents aged ≥45 years in Central Java. Nutritional status was assessed using Body Mass Index (BMI). Sociodemographic characteristics, consumption patterns, and physical activity were analyzed using chi-square tests and multivariate logistic regression to estimate Adjusted Odds Ratios (aOR). Results: 42.2% of respondents were overweight or obese. Risk factors included age ≥60 years (aOR=1.695), urban residence (aOR=1.349), and daily sweet beverage consumption (aOR=1.374). Protective factors included male sex (aOR=0.414), low education (aOR=0.628), marital status (married/widowed), and heavy physical activity (aOR=0.808). Moderate physical activity was not significant after adjustment. Conclusion: Obesity among pre-seniors and seniors in Central Java is influenced by demographic, social, and behavioral factors, indicating the need for tailored prevention strategies for older adults.
