Abstract

Disease infection is a problem in catfish farming. The diseases that often arise in catfish farming is Motile Aeromonas Septicemia (MAS). It can infect the catfish group with a high mortality rate. Watercress extract is thought to inhibit the growth of pathogenic bacteria that infect catfish. Bacteria that infect catfish are cultured and biochemically identified. The extracts test was carried out through an inhibition tests with different doses to determine the activity of extracts in inhibiting bacterial growth. Based on the results of biochemical identification, the pathogenic bacteria that infect catfish are Aeromonas hydrophila. The results of the inhibition test showed that a dose of 70 ppm had the highest inhibitory response compared to other doses. This indicates that watercress macroalgae extract can inhibit the growth of pathogenic bacteria so it can be used as an alternative medicine to treat Aeromonas hydrophila infection in fish.

Abstract

For children, playing is one of the fun and exciting activities. Because playing can develop children's creativity. One of them is the papercraft game, which is an art where you combine several origami papers into real 3D. How to make this papercraft by cutting, folding, and also sticking an origami paper. This study aims to determine the effect of papercraft games on creativity in children aged 5-6 years at Asmaul Husna Islamic Kindergarten. The method used by the researcher is Pre-Experimental Design, with the type of One-Group Pretest-Posttest Disgn. Determination of the sample in this study using the purposive sampling technique, because the sample used was in accordance with the needs. The sample used in this study amounted to 13 children. Data collection techniques in this study used observation of treatment to determine the results given. The results of the t-test calculation using a significant level (α) 0.05 and n=13-1=12 obtained t_hitung=10,174 and t_table=1,78. Therefore, it can be concluded that t_hitung>t_tabel or 16.11>1.78 which means H_O is rejected and H_a is accepted. This means that the hypothesis which states that papercraft games have an optimal effect on the creativity of children aged 5-6 years in Asmaul Husna Islamic Kindergarten.

Abstract

Tilapia (Oreochromis niloticus) is a highly valuable aquaculture species, yet handling and transportation processes often induce stress that can reduce survival. Anesthetics are commonly used to minimize stress, but synthetic agents may leave residues and potentially harm both fish and consumers. Therefore, natural plant-based anesthetics are increasingly explored as safer alternatives. This study aimed to evaluate the effectiveness of galangal (Alpinia galanga), bandotan (Ageratum conyzoides), and frangipani flower (Plumeria acuminata) extracts as natural anesthetic agents for tilapia fry during transport. The experiment used a completely randomized design with three treatments and five replications. Tilapia fry (3–5 cm) were exposed for six hours to plant extracts at predetermined doses. Measured parameters included induction time, recovery time, and survival rate. Data were analyzed using ANOVA followed by Tukey’s test. The results indicated significant differences among treatments. Galangal extract produced the fastest induction (3.9 minutes), quickest recovery (5.5 minutes), and highest survival rate (99.6%). Bandotan extract showed moderate performance, while frangipani flower extract produced the slowest induction, longest recovery, and lowest survival (82%). Overall, galangal extract proved to be the most effective and safest natural anesthetic. The study demonstrates that plant-based anesthetics can reduce transport-related stress without leaving harmful residues, offering practical benefits for sustainable aquaculture, especially in wet transport systems.
