Abstract

Environmentally friendly synthesis of barium titanate (BaTiO3) nanoparticles was conducted using natural leaf extracts of Moringa oleifera, Musa spp., Pometia pinnata, and Terminalia catappa as green dopants via the sol-gel method. This study aims to evaluate the influence of different leaf extracts on the optical properties of BaTiO3 characterized by UV-Vis spectroscopy. Each sample exhibited distinct absorption spectra, reflecting variations in phytochemical composition among the extracts. The results showed that Terminalia catappa and Pometia pinnata extracts produced the highest band gap values, 3.36 eV and 3.35 eV respectively, indicating optical activity in the ultraviolet region. Musa spp. extract resulted in a band gap of 2.81 eV, while Moringa oleifera extract yielded the lowest value of 2.59 eV. These differences suggest that the type of plant extract significantly affects the optical characteristics of the synthesized BaTiO3. This research highlights the potential use of local biomass in the development of functional BaTiO3-based materials through green synthesis approaches.

Abstract

Leptospirosis is a zoonotic disease that is transmitted through contact with the urine of infected animals, especially rats, and often occurs in environments with poor sanitation. This study aims to analyze behavioral risk factors and environmental conditions that contribute to the spread of leptospirosis in Pematang Pasir Village, Teluk Nibung District, Tanjung Balai City in 2024. The study used a cross-sectional design involving 50 respondents aged 17 years and older from Wards I and VI. Data were collected through interviews using questionnaires that assessed respondents' knowledge, attitudes, and actions related to leptospirosis, as well as direct observation of environmental conditions such as waterlogging, the presence of rats, and sanitary conditions. The results showed that the majority of respondents (88%) had low knowledge about leptospirosis, although 80% implemented good personal hygiene behaviors. Only 18% of respondents carried out adequate rat control measures. Environmental observations revealed that 96% of respondents experienced puddles around their homes, and 100% indicated that their neighborhoods were flooded frequently. The presence of garbage around the house was found in 98% of respondents, and 98% of respondents often saw rats in or around the house. Most respondents (90%) had a house ≥ 2 meters away from the sewer, with 92% reporting good road conditions. Only 24% of respondents have pets, and 4% live close to ponds (< 700 meters). Factors such as poor sanitation, the presence of rodents, and the high risk of flooding are the main factors that affect the risk of spreading leptospirosis in the region. This study emphasizes the importance of increasing public education about leptospirosis and its prevention measures, as well as environmental improvement efforts to reduce the risk of infection in the affected areas.

Abstract

The issue of waste is a very pressing matter that requires serious attention because it has a direct impact on the environment, health, and the sustainability of human life. This study aims to increase the knowledge and attitudes of Islamic boarding school students. The objective of the study is to improve knowledge and attitudes to care for and heal Islamic boarding school students through the synergy of Islamic ecotheology and counseling in waste education. The type of research used in this study is quasi-experimental research with a one-group pretest-posttest design. This study involved 30 santri who were selected purposively based on recommendations from the pesantren. The statistical test used was the Paired Sample t-Test with the help of JASP version 16 computer software. The results of this study show that interventions in the form of counseling can significantly improve the knowledge and attitudes of santri regarding Islamic ecotheology and waste management in pesantren. The Wilcoxon test results showed a significant increase in knowledge (p < 0.001), while the Paired Sample t-Test showed an increase in attitude from an average score of 26.60 on the pretest to 36.10 on the posttest with a p-value < 0.001. This confirms that counseling not only improves conceptual understanding but also encourages positive attitude changes that have the potential to continue in real behavior in maintaining the cleanliness and sustainability of the pesantren environment.
