Abstract

Disease attacks on tiger shrimp (Penaeus monodon) have developed in several pond areas, resulting in mass mortality and crop failure. One of them is vibriosis disease caused by the bacteria Vibrio parahaemolyticus. V. parahaemolyticus bacteria are one of the most virulent and prevalent pathogens against tiger shrimp cultivation and cause substantial economic losses to the aquaculture industry. This study aimed to analyze the antibacterial effectiveness of noni (Morinda citrifolia) leaf extract on shrimp larvae against V. parahaemolyticus in vivo. The research method was carried out experimentally with several stages: noni leaf extraction with maceration using 80% ethanol, phytochemical tests, and antibacterial tests through maintenance with extract immersion (control without extract, extract immersion for 1 hour, 2 hours, 4 hours, 8 hours, 16 hours, and 24 hours), bacterial enumeration, and water quality measurement. The results showed that tiger prawn larvae infected with V. parahaemolyticus bacteria experienced clinical symptoms with reddish color, passive swimming patterns, sideways movements, and very active reflex movements. The antibacterial effectiveness of noni leaf extract on tiger prawn larvae significantly affected V. parahaemolyticus bacteria. The content of compounds in noni leaf extract suppresses the mortality rate of tiger prawn larvae due to V. parahaemolyticus bacterial infection. The best dose was found in the extract soaking for 1, 2, 4, and 8 hours, with tiger prawn larval mortality up to 0% during maintenance.

Abstract

This study aims to examine the role of self-compassion in mental load among high school students. The study employed a quantitative correlational design and involved 262 students from three high schools in Yogyakarta. Data were collected using the Mental Load Scale and the Self-Compassion Scale. Based on the results of this study, both instruments showed adequate validity and reliability as indicated by AVE, Cronbach’s Alpha, and Composite Reliability values. Analysis was conducted using Partial Least Squares (PLS) based Structural Equation Modeling with SmartPLS 4.0. The validity results showed that all aspects had an Average Variance Extracted (AVE) > 0.50, while internal reliability for all aspects was good with Cronbach’s Alpha and Composite Reliability >0.70. The results showed that total self-compassion had a significant role in total mental load (β = 0.133, p < 0.05) and mental load aspects (β = 0.025, p < 0.05). However, total self-compassion also played an indirect role in mental effort aspects through total mental load as a mediator (T-statistic > 1.96, p < 0.05). The R-square values indicate strong predictive ability in most aspects, including the mental load aspect (0.942) and the mental effort aspect (0.936). These findings indicate that students with higher levels of self-compassion tend to cope more adaptively with academic and emotional pressures. Therefore, school-based guidance and counseling services can be utilized to help students manage mental load by strengthening self-compassion through individual or group counseling.
