Abstract

The use of disposable baby diapers continues to increase in line with population growth and lifestyle changes that prioritize convenience. However, baby diaper waste has become a significant environmental issue due to its synthetic and chemical components that are difficult to decompose naturally. This study aims to apply hydrothermal machine technology as an environmentally friendly and efficient solution for processing baby diaper waste. Hydrothermal technology utilizes high temperatures and pressure to decompose organic and synthetic materials in diapers, resulting in reusable products such as construction materials, alternative energy, or fertilizers. The study results show that the hydrothermal process can reduce diaper waste volume by up to 90% and produce valuable materials. The implementation of this technology supports waste reduction at landfills (TPA) and advances the vision of zero waste, making it a sustainable solution for waste management challenges.

Abstract

This study aims to analyze the impact of architectural design on user behavior in the Civil Engineering Laboratory Building and Buildings C2 and C3 at the Faculty of Engineering, Gorontalo State University. Data were collected through direct observation, site surveys, and interviews with space users. The results showed that space design, considering thermal comfort, circulation layout, and social spaces, significantly influenced students' academic and social behaviors. However, challenges such as limited social spaces and inadequate ventilation systems affected comfort and interaction. The study also provides recommendations to improve design, such as adding green elements, expanding social spaces, and optimizing ventilation systems. These changes are expected to create a more sustainable environment, support better social interactions, and increase user productivity.
