Abstract

This study investigates the potential of natural stimulants, specifically ecdysteroids, in accelerating the molting process in mangrove crabs. The research was conducted by analyzing various plants containing ecdysterone and their effects on the crabs. The results indicate that forest fern leaves and mulberry leaves are effective sources of ecdysterone in stimulating molting and growth in crabs. The use of such natural stimulants has the potential to enhance productivity and reduce reliance on synthetic hormones in crab cultivation. However, further research is needed to determine the optimal dosage and to understand the mechanisms of ecdysterone action in crabs in more detail. The main challenge in implementation is adjusting the dosage and frequency of natural stimulant administration to achieve optimal results without disrupting the balance of the cultivation ecosystem. This approach offers an environmentally friendly alternative for the sustainable development of crab farming.

Abstract

The many herbal plants in Indonesia that contain antimicrobial substances such as Calotropis gigantea, Moringa oleifera and Cassia alata L. leaves are attractive and have the potential to be used to prevent and treat bacterial diseases in fish. This study aims to determine the effectiveness of administering a combination of multi-herbal ingredients, namely M. oleivera, C. gigantea and C. alata L. leaves in the treatment of O. niloticus tilapia infected with the pathogenic bacteria S. agalactiae. The experimental design used a completely randomized design with 6 treatment levels and 3 replications, namely treatment A (Fish that were not infected with S. agalactiae), B (Fish infected with S. agalactiae), C (Fish infected with S. agalactiae + soaked in thistle leaf extract 800 ppm+ Moringa leaf extract 1000 ppm)), D (Fish infected with S. agalactiae + soaked in C. gigantea leaf extract 800 ppm + C. allata leaf extract 10 ppm), E (Fish infected with S. agalactiae +soaked in Moringa leaf extract 1000 ppm + C. allata leaf extract 10 ppm) and F (Moringa leaf extract 1000 ppm+C. gigantea leaf extract 800 ppm + C. allata leaf extract 10 ppm). The results showed that the combination of M. oleivera, C. gigantea and C. alata L. extracts had a significant effect (P0.05) on the survival rate ofO. niloticus. Treatment (E), combination of M. oleivera leaf extract 1000 ppm + C. alata L leaf extract 10 ppm, showed the fastest healing of the body and the highest survival rate of tilapia, namely 80%.Keywords:Multi herbal leavesPatoghenImunnity

Abstract

Microplastics, or plastic particles smaller than 5 mm, are a growing ecotoxicological problem for both human health and aquatic habitats. Even though microplastic pollution affects the air, water, and land widely, these habitats are often viewed as distinct from one another while in fact they are tightly related. The purpose of this work is to review the body of scientific literature on microplastic studies in Indonesian watershed sediment. Google Scholar has identified around 57 papers about microplastic pollution that were published between 2017 and 2023. Papers about sediment for rivers, lakes, marine, and estuaries are categorized further based on (i) their occurrence and characterization, (ii) their intake by and effects on species, and (iii) their fate and transport issues. Even at low concentrations of 10 g/mL, microplastics cause harmful effects for people and animals, including cytotoxicity, immunological response, oxidative stress, barrier characteristics, and genotoxicity. When marine animals eat microplastics, their gastrointestinal tract physiology changes, and they also experience immune system depression, oxidative stress, cytotoxicity, differential gene expression, and growth inhibition. In addition, the bioaccumulation of microplastics in aquatic creatures' tissues may harm the aquatic ecosystem and may spread to people and birds. Through behavioural changes and policy changes, such imposing taxes, bans, or price increases on plastic carrier bags, plastic usage has been dramatically decreased to 885% in many different nations across the globe. The strategy for minimizing microplastics is structured like an upside-down pyramid: prevention is at the top, then reduction, reuse, recycling, recovery, and, as the least desirable alternative, disposal.Keywords:MicroplasticsSedimentIndonesia WatersEnvironmental RiskPollutant Aquatic
