Abstract

This research investigates the effectiveness of papaya leaf extract (Carica papaya L.) as a bioinsecticide against stable flies (Stomoxys calcitrans) and aims to identify the most effective concentration and solvent for killing these pests. Conducted using a Completely Randomized Design (CRD), the study utilized papaya leaf extracts obtained through maceration at concentrations of 10%, 15%, and 20%, with 96% ethanol and aquades as solvents. Phytochemical analysis confirmed the presence of beneficial compounds such as alkaloids, flavonoids, and saponins. The one-way ANOVA results revealed a significant impact of the ethanol-based extract on fly mortality, with a p-value of 0.00, while aquades showed no significant effect (p = 0.065). Notably, a 20% concentration of the ethanol extract achieved 100% mortality of stable flies within 50 minutes, indicating that papaya leaf extract is a cost-effective and environmentally friendly bioinsecticide, particularly when using ethanol as a solvent.

Abstract

The process of extracting active compounds from Moringa leaves requires efficient techniques so that active compounds can be isolated in high concentrations without damaging the chemical structure. The tool commonly used is a rotary evaporator. This research analyzes the percentage of solvent evaporation using a Rotavap Extractor and a conventional rotary evaporator. Both tools aim to maximize solvent evaporation by retaining active compounds from the extract. This research compares the effectiveness of the two tools based on the percentage of solvent evaporated and the viscosity of Moringa leaf extract with different time variations (40, 60, 80 minutes). The percentage of solvent that evaporates has an important role in determining the concentration and viscosity of Moringa leaf extract. As more solvent evaporates, the extract becomes more concentrated, increasing the viscosity due to the high concentration of active compounds. The percentage of solvent evaporated and viscosity show the same trend between the conventional rotary evaporator and the rotavap extractor, this indicates that both devices work with similar efficiency in evaporating solvent from Moringa leaf extract.

Abstract

This study aims to examine the effect of self-disclosure and social media addiction on social anxiety in emerging adult users of Instagram's close friends feature among students in Semarang, in accordance with the formulation of the problem which aims to determine whether the two independent variables have a significant effect on the dependent variable. This study uses a quantitative method and a sample of 176 students, the study collected data through an online questionnaire (google form) with a Likert scale and analyzed using multiple linear regression. The results show that social media addiction has a significant effect on social anxiety (p <0.05, coefficient 0.5138), while self-disclosure does not have a significant effect, with the majority of respondents in the moderate category to the third variable. This study proves that social media addiction has an important role in increasing social anxiety in emerging adults in the digital era, contributing to understanding the psychological dynamics of social media users.

Abstract

The increasing consumption of plastic, particularly single-use packaging, has led to a significant rise in household plastic waste, which poses a potential threat to environmental sustainability. One type of waste that remains underutilized is metallic plastic packaging. This Community Service activity aimed to enhance community knowledge and skills in processing metallic plastic packaging waste into handicraft products with functional value and economic potential. The activity was conducted in collaboration with the Family Welfare and Empowerment Group (PKK) of Ngringo Village, Karanganyar, involving 15 participants. The methods employed included a preliminary survey, educational outreach, hands-on practical training, and continuous mentoring. The effectiveness of the program was evaluated using pre-test and post-test assessments analyzed through the normalized gain (N-gain) method. The results demonstrated an improvement in participants’ knowledge and skills following the training, with an average N-gain value of 0.68, which falls within the moderate-to-high category. These findings indicate that the metallic plastic packaging waste processing training was effective in enhancing community capacity. Furthermore, the activity not only contributed to reducing plastic waste generation but also promoted the implementation of circular economy principles.
