Abstract

The use of thiosulfate as a chlorine neutralizer in water sterilization for vannamei shrimp hatchery culture is essential for maintaining water quality and minimizing organism stress. Thiosulfate effectively eliminates residual chlorine that may be harmful to cultured shrimp, thereby supporting improved cultivation success. This quantitative combined-method study was conducted at the Aquaculture Wet Laboratory of Universitas Almuslim from August to September 2024. The results showed that salinity in treatments A, B, C, and D was consistently 30‰. The highest pH value was recorded in treatment D replicate 2 (8.16), while the lowest was in treatment A replicate 3 (8.10), with an overall average of 8.12. Water temperature across all treatments ranged from 31 to 32°C. Dissolved oxygen (DO) levels were highest in treatment B replicate 1 (5.44 mg/L) and lowest in treatment A replicate 1 and treatment D replicate 2 (5.20 mg/L). Ammonia concentrations in all treatments and replicates were 0.0 mg/L. The highest chlorine concentration was observed in treatment A replicate 3 (0.10 mg/L), whereas treatments C and D showed 0.00 mg/L across all replicates. Bromine levels were also highest in treatment A replicate 3 (0.18 mg/L), with treatments B, C, and D consistently at 0.00 mg/L. Vibrio density in treatments A, B, and C was 0, while treatment D recorded 2,500 CFU/mL in replicate 1, 2,600 in replicate 2, and 8,000 in replicate 3.

Abstract

Bireuen Regency has the potential for coastal ecosystem resources. There are two Fish Landing Sites (PPI) with very high activity, namely PPI Peudada and PPI Jangka. The high level of activity leads to concerns about pollution, one of which is the presence of lead (Pb) metal. This research aims to assess the characteristics of mangrove areas, seawater samples for heavy metals Pb, and sediments around the coastal fishing port area of Bireuen Regency. The study was conducted in 2024. Research was carried out at two sampling locations of the Fish Landing Sites (PPI), namely the Peudada Fishing Port and the Jangka Fishing Port using purposive sampling methods. At the BARISTAND (Aceh Research and Industrial Standardization Agency) laboratory, samples were analyzed using an AAS (Atomic Absorption Spectrophotometer). The Pb concentrations in seawater and sediment at first Location (Peudada) were <0.0003 mg/L and 2.60 mg/kg, respectively. At second Location (Jangka), the concentrations were <0.0003 mg/L and 1.78 mg/kg, respectively. Observational results indicate that Pb metal contamination in seawater and sediment at locations 1 and 2 is still below the threshold limit set of Ministry of Environment No. 51 in 2004 and RNO in 1981.

Abstract

This study aimed to characterize pathogenic bacteria and analyze the level of hepatopancreatic tissue damage in whiteleg shrimp (Litopenaeus vannamei) originating from pond and hatchery cultivation systems in Jangka and Simpang Mamplam Districts, Bireuen Regency. Shrimp samples were collected from two types of water locations that receive aquaculture waste runoff, namely estuarine stations (aquaculture pond effluent) and coastal marine stations (hatchery effluent). Bacterial analysis was carried out through isolation on agar media and identification of colony morphology and biochemical tests, while histopathological analysis was carried out on hepatopancreatic tissue using the Hematoxylin–Eosin (H&E) staining method with a semi-quantitative scoring system. The results showed that the identified pathogenic bacteria included Aeromonas hydrophila, Vibrio parahaemolyticus, Photobacterium damselae, Vibrio alginolyticus, and Vibrio vulnificus with densities ranging from 10³–10⁷ CFU. The highest bacterial density was found at the estuarine station, especially from the genus Vibrio. Histopathological analysis revealed various structural changes in hepatopancreas tissue, including cell lysis, vacuolization, hemocyte aggregation, tubular damage, and inflammatory responses. Histopathological scores at the estuarine station (3.67–4.00) indicated a more severe level of tissue damage compared to the marine station (2.67).

Abstract

Stunting remains a chronic nutritional problem and a major challenge in public health development in Indonesia. One of the contributing factors to stunting is the low intake of animal protein, particularly fish, due to limited public knowledge and dietary habits. This community service activity aimed to improve community knowledge and understanding of the importance of fish consumption as an effort to prevent stunting through the socialization of the Community Movement for Fish Consumption (Gerakan Masyarakat Makan Ikan/Gemarikan). The activity was conducted in Banda Masen Village, Lhokseumawe City, in June 2024, targeting community members, especially housewives and families with toddlers. The method applied an educational and participatory approach through lectures, interactive discussions, fish-processing demonstrations, and evaluation using pretest and posttest questionnaires. The results showed an increase in community knowledge across all assessed aspects, including understanding of stunting, nutritional content of fish, benefits of fish consumption, and healthy and attractive fish-processing methods. High community participation during the activity also indicated a positive response to the implemented program. Therefore, the socialization of Gemarikan proved to be effective in enhancing community nutritional knowledge and has the potential to support stunting prevention efforts at the community level.   Keywords: Community Movement for Fish Consumption, Lhokseumawe City, Stunting, Community Service

Abstract

Stunting remains a major public health issue in Aceh Province, including Bireuen Regency, which records a prevalence of 26.5%. One of the main contributing factors is the improper provision of complementary feeding (MP-ASI), particularly regarding nutritional composition and the limited use of local food ingredients. This community service program aimed to enhance the capacity of Posyandu cadres in Pante Karya Village to develop locally sourced complementary foods as a strategy to prevent stunting. The methods included education sessions, hands-on MP-ASI preparation training, and post-training mentoring through field visits. The results showed an increase in cadres’ knowledge and skills in designing nutritionally balanced MP-ASI menus, with an average knowledge improvement of 35%. Participants successfully utilized local food ingredients such as fish, tempeh, and vegetables as sources of protein and micronutrients. This program demonstrates that participatory and practical-based training effectively improves cadre capacity and contributes to sustainable stunting prevention efforts at the community level.

Abstract

Bacterial diseases are among the major factors limiting the productivity of mud grouper (Epinephelus coioides) aquaculture. This study aimed to isolate and identify bacteria from the kidney, gills, and skin mucus of mud grouper cultured in floating net cages in Lhokseumawe, Aceh, Indonesia. The study was conducted from August to September 2024 using an observational method combined with laboratory-based analysis. A total of ten fish (approximately 20 cm in length) showing clinical signs of bacterial infection, including lethargy, erythema, and hemorrhage, were selected using purposive sampling. Bacterial isolation was performed on 3% Tryptic Soy Agar (TSA) and incubated at 26–30°C for 24 h. The isolates were identified using the Analytical Profile Index (API) Kit. The results revealed the presence of Vibrio alginolyticus, Vibrio harveyi, Streptococcus iniae, and Bacillus cereus. Vibrio alginolyticus and Vibrio harveyi were isolated from the kidney and gills, whereas Streptococcus iniae was detected in the gills and skin mucus. Bacillus cereus was identified only from the skin mucus. These findings provide baseline information on bacterial diversity associated with cultured mud grouper and may support disease diagnosis and fish health management in floating net cage aquaculture.
