Abstract

This study aims to determine the immunity response of  Carassius auratus infected with Aeromonas hydrophila bacteria and post-treatment with propolis solution by measuring total leukocytes and phagocytosis index. The method used is experimental by applying a completely randomized design (CRD) with five treatments and three replications. The treatments were Kn (not infected with A. hydrophila and not treated with propolis), Kp (infected with A. hydrophila but not treated with propolis), while fish infected with A. hydrophila were treated with propolis doses P1 (700 ppm), P2 (800 ppm), and P3 (900 ppm). Treatment was done by injecting 0.1 ml of propolis into fish infected with A. hydrophila intramuscularly. The test material was 150 fish of 8-10 cm in size. The results showed that propolis significantly gave an immune response to the C. auratus infected with A. hydrophila (p<0.05). The 800 ppm propolis dose was the most effective, as indicated by a total leukocyte count of 3.70×104 cells/mm3, a phagocytosis index value of 28.33%, and a survival rate of 83.33%. This study highlights that propolis has potential as a natural immunostimulatory agent in enhancing non-specific defense mechanisms in C. auratus infected with pathogenic bacteria

Abstract

Children's problems in maintaining cleanliness and health still face significant challenges. Therefore, handling is needed, one of which is socialization, to build awareness of clean and healthy living among children (PHBS). PHBS is a crucial step in shaping Indonesia's future golden generation. This service was carried out in November 2024 at Madrasah Ibtidaiyah Negeri 11 Rukoh, Banda Aceh City. The participants in this clean and healthy environment socialization activity are 38 students. The purpose of this socialization is to raise awareness about the importance of maintaining environmental cleanliness in schools by involving students. The materials covered in the socialization are washing hands with soap and clean water, consuming healthy and nutritious food, disposing of waste in designated areas, maintaining toilet cleanliness, and exercising regularly. The results of the service show that the majority of elementary school students already understand and have practiced these positive activities. Two-way communication is well-established. This is demonstrated by the enthusiasm of the students in listening, answering, and providing positive feedback on this activity. Therefore, this service activity was successfully carried out and yielded good results for the students' ability to maintain a healthy and clean lifestyle, both at school and when at their respective homes.

Abstract

Coastal ecosystems are highly sensitive to nutrient enrichment, particularly from land-based activities and aquaculture effluents, which contribute to water quality degradation. This study evaluated the concentrations of nitrate, ammonia, and phosphate in the coastal waters of Buruk Bakul Village, Bengkalis, Riau Province, Indonesia. Water samples were collected from four representative stations in August 2025: a river estuary, a shrimp pond, a mangrove rehabilitation site, and a natural mangrove forest. The analysis was conducted using spectrophotometric methods in accordance with the Indonesian National Standards (SNI). Results indicated that nitrate concentrations ranged from 0.0822 to 0.1932 mg/L, ammonia from 0.5705 to 1.7338 mg/L, and phosphate from 0.0845 to 0.299 mg/L. All parameters exceeded the seawater quality standards for marine biota established by the Decree of the Minister of Environment No. 51/2004, indicating a significant anthropogenic influence. The river estuary recorded the highest nitrate and phosphate levels, reflecting inputs from land runoff and domestic waste, while ammonia peaked in the shrimp pond due to aquaculture discharge. Nutrient levels in mangrove-associated stations were lower but still above the threshold, indicating that mangrove ecosystems provide some capacity to retain and transform nutrients, although insufficient for full remediation. Elevated nutrient concentrations pose ecological risks, such as eutrophication and algal blooms, which may disrupt biodiversity and fisheries productivity. This study emphasizes the urgency of improving aquaculture waste management, reducing land-derived nutrient loading, and strengthening mangrove conservation and rehabilitation as integrated strategies to sustain coastal ecosystem health in Buruk Bakul and similar regions. These findings provide a baseline for nutrient management and coastal rehabilitation strategies in western Indonesian waters
