Abstract

This study presents the development and application of an innovative 3-in-1 nanotechnology pyrolysis reactor designed to simultaneously produce liquid smoke, activated carbon, and limestone from locally sourced raw materials in Jambi Province, Indonesia. The multifunctional reactor combines three production processes, which are traditionally performed separately, into a single, efficient unit, addressing both economic and environmental challenges. Coal serves as the primary heat source and material for activated carbon, whereas shell waste is calcined to produce limestone. The reactor operates at temperatures exceeding 550°C to ensure optimal conversion, with a glass wool insulator replacing clay to enhance thermal efficiency. The liquid smoke undergoes further distillation to achieve purification, while residual activated carbon is chemically activated with H₃PO₄ to enhance its adsorption capacity. The experimental results demonstrate that this reactor can produce high-quality products with minimal resource wastage. This 3-in-1 pyrolysis reactor represents a sustainable, cost-effective solution for resource-limited settings, with broad potential for application in waste-to-product conversion, environmental remediation, and rural development.

Abstract

The COVID-19 pandemic has increased online shopping and food delivery, causing a surge in single-use plastic waste and has become a habit to this day along with the rapid development of digital technology. Dream Central Waste Bank (BSI Dream) in Wijaya Pura Village collects 3 tons of waste monthly but lacked advanced plastic processing technology. This community service initiative aimed to implement a pyrolysis reactor to convert plastic waste into fuel oil and paving blocks, thereby enhancing economic value while promoting environmental sustainability. The activity stages included partner coordination and surveys, reactor performance upgrades, operational training, and evaluation. This activity involved five partners representing the Wijaya Pura Village community.  The reactor successfully produced fuel oil (density: 0.848–0.912 g/mL) and residues suitable for paving block production. The outcome of this initiative demonstrated improved skills among partners, the creation of marketable products and increased community income opportunities. Furthermore, the activity fostered greater awareness of the importance of sustainable waste management and supported the application of circular economy principles.

Abstract

Stunting is a growth disorder in children caused by inadequate nutrition, affecting their physical and cognitive abilities. One contributing factor to stunting is early marriage, which is closely related to a low understanding of adolescent reproductive health. This study aims to analyze the effect of animated educational video media on adolescents' knowledge of reproductive health in efforts to prevent stunting. This quantitative study uses a pre-experimental design with a one-group pre-test and post-test arrangement. Data collection uses total sampling with 66 respondents. The research is conducted at SMPN 5 Satap Kunto Darussalam. The measurement tool is a validated and reliable questionnaire on reproductive health, sexuality, and teenage pregnancy prevention. The data is analyzed using the Wilcoxon test. The results show an increase in adolescents' knowledge before and after the intervention with animated educational video media. Statistical tests confirm that the intervention is effective in improving adolescents' average knowledge regarding reproductive health, with a p-value of 0.000 ( α 0.05). Animated educational video media effectively improves adolescents' knowledge about reproductive health in efforts to prevent stunting. This media can serve as a useful tool for adolescents to enhance knowledge and actions related to reproductive health and stunting prevention.

Abstract

Remazol Yellow is a dye that contains an basic amino group and a benzene core, so it is difficult to be naturally degraded by microorganisms and causes environmental pollution. One solution to reduce the dye waste polluted in waters can be done by adsorption method using pineapple peel cellulose as adsorbent. Before turning into pineapple peel cellulose, the NaOH delignification process and H2SO4 hydrolysis were carried out first. The adsorption process for rhodamine B dye was carried out on 2 parameters, namely pH, contact time and determination of the adsorption system using the Langmuir and Freundlich equations at various concentrations of 5, 10, 15, 20, 25, 50, 75 and 100 ppm. Testing the effect of pH on the adsorption of Remazol Yellow was carried out with variations in pH namely 2, 3, 4, 5, 6, 7 and 8. . The results showed the optimum conditions at pH 2, contact time of 30 minutes and the Langmuir isotherm adsorption system with an adsorption capacity of 19.888 mg/g
