Abstract

Antibiotics cause resistance to pathogenic bacteria, and the emergence of resistance and bacterial pathogenic infections makes scientists try to find new drugs. One of the efforts is to use marine organisms as a natural antibacterial agent, one of them is Sargassum sp. Sargassum sp contains alginate and iodine which are used in the food, pharmaceutical, cosmetic and textile industries. Apart from that, Sargassum sp. contains active compounds of steroids, alkaloids, phenols and triterpenoids which function as antibacterials, can be used to inhibit the growth of Vibrio sp bacteria which is the cause of firefly disease which is most dangerous for tiger prawns. The purpose of this study was to determine the ability of the extract Sargassum sp. In inhibiting the growth of Vibrio parahaemolyticus bacteria with different levels of solvent start with methanol, ethyl asetat, and n-hexane. The rejuvenation of Vibrio parahaemolyticus and Vibrio harveyimelalai bacteria is carried out in two stages, the first is planting on Triptyc Soy Broth (TSB) medium and the second stage is planting on Triptyc Soy Agar (TSA) medium.  Antibacterial sensitivity test using disc diffusion method. The results of the test showed that 1). sargassum sp which is extracted by metanol solvent inhibits the growth of Vibrio parahemolyticus bacteria. 2). sargassum sp which extract by etil sestat and n - heksan solvent can't inhibit the Vibrio parahemolyticus bacteria.

Abstract

East Sinjai District is one of the main aquaculture centers in Sinjai Regency, South Sulawesi, with milkfish (Chanos chanos) and whiteleg shrimp (Litopenaeus vannamei) as its primary commodities. However, pond productivity remains fluctuating due to unstable water quality and the limited ability of farmers to independently monitor environmental parameters. This community service program aimed to enhance the capacity of local fish farmers through education and training on the use of water quality measuring instruments (thermometer, pH meter, and refractometer) as well as pond water quality monitoring techniques. The activity was conducted on September 12, 2025, in East Sinjai District, involving ten (10) fish farmers and lasting for four weeks. The method used was a participatory approach, covering stages of socialization, training, field practice, and mentoring. Farmers were trained to use simple measuring tools such as thermometers, pH meters, and refractometers, and were taught calibration procedures, data recording, and interpretation of measurement results. The results showed improved farmers’ skills in monitoring key water quality parameters (temperature, pH, and salinity), as evidenced by water quality monitoring conducted by five (5) participants. This program successfully enhanced farmers’ awareness, technical skills, and independence in maintaining pond environmental quality. Furthermore, it holds potential for sustainability through the formation of independent farmer groups and continued training on waste management and eco-friendly aquaculture technologies.
