Abstract

Character education can be interpreted as ethics education, moral education, value education, character education, which aims to develop students' abilities in determining good and bad, maintaining what is good, and applying these good in everyday life. The purpose of implementing this Community Service is to increase Partners' knowledge about Character Education so that it can become a stronghold in the person of each participant to dare to refuse invitations to use Narcotics. The implementation method in this counseling activity uses face-to-face and still pays attention to health protocols with the capacity of counseling participants around 15 participants of the Management and Members of Karang Taruna Kelurahan Karet, Setia Budi District, South Jakarta. From the results of the Community Service Program activities, results were obtained based on the Post-test , there was an increase in knowledge of the dangers of narcotics and sanctions for users and dealers and an increase in knowledge of character education.

Abstract

This study assessed climate classification, hydrological conditions, and agricultural vulnerabilities in Pangkalpinang City, Bangka Belitung Province, Indonesia, using a 65-year (1959-2024) daily meteorological dataset. Climate classification revealed a dominant Af (Tropical Rainforest) type by the Köppen-Geiger method (occurring in 56 out of 66 years) with high precision (0.89-1.0) and a C1'As (perhumid mesothermal) classification predominating according to Thornthwaite (64 out of 66 years). Trend analysis showed a likely not significant temperature increase (approximately +0.02°C/year) and shifting precipitation patterns, with mean annual rainfall at 2289.84 mm and an annual precipitation concentration index (PCI) of 8.924, indicating a moderately irregular rainfall distribution. Hydrological analysis showed an average potential evapotranspiration (PET) of 0.284 mm, a soil moisture content of 99.751 mm, an average surface runoff of 4.577 mm, and 51 annual flood risk events, exhibiting a humid regime. Mean crop water requirement (CWR) was 4.857 relative units, and we observed a strong positive correlation (r=0.969) between the water requirement satisfaction index (WRSI) and crop water needs. The model validation exhibited a root mean square error (RMSE) between 0.1-0.5 and showed a stable Thornthwaite classification even with perturbations and the time series data analysis revealed the variability of parameters and a shift in temperature around the year 2000. These results emphasize the urgent need for localized climate adaptation strategies in Pangkalpinang.

Abstract

The vast quantities of rice straw residue generated every year present both a challenge and an opportunity. To address the challenge, this work took the opportunity by transforming rice straw waste into eco-friendly silica gel. Synthesis of rice straw-based silica gel was via sol-gel method with the calcination temperature of 700 oC for 2 h and the addition of sodium hydroxide 2 molar. Characteristics of silica gel and its raw material have been investigated using several techniques such as FTIR, XRD, SEM, and BET surface area. The synthesized silica gel showed obvious peaks of Si-O-Si and O-H, aggregated smaller particles, crystal nature, and high surface area. This innovative work contributes to agricultural waste management and the circular economy for a sustainable future.

Abstract

Marine macroalgae, or seaweeds, have emerged as promising sources for the green synthesis and stabilization of nanoparticles, offering remarkable potential in photodegradation processes. These abundant and renewable resources harbor a diverse array of bioactive compounds, including polysaccharides, proteins, flavonoid, and pigments, which can act as reducing, capping, and stabilizing agents. The integration of macroalgae-derived stabilizing agents into nanoparticle synthesis confers unique properties, enhancing photocatalytic performance and stability. This review comprehensively examines the role of marine macroalgae as stabilizing agents for bio-fabricated nanoparticles in photodegradation applications in particular for toxic azo dye degradation and organic compounds. It explores into the mechanisms of nanoparticle synthesis and stabilization, explores the diverse macroalgal species employed, and evaluates their photocatalytic efficiency against various organic and inorganic pollutants in wastewater. Furthermore, the review critically analyzes the challenges and future perspectives in this field, offering insights into the development of green, sustainable, and efficient remediation strategies for environmental contaminants.
