This research was carried out from September to October 2022 at UPR Mina Mandiri Gampong Lhok Seumot, Beutong District, Nagan Raya Regency. This study used bile fish seeds measuring 2 - 2.25 cm in length as test fish. The experimental design used was a non-factorial, Completely Randomized Design (CRD) with four treatments and three replications. The level of treatment applied in the feed formulation was control feed without fermented water hyacinth flour substitution (P0), 5% fermented hyacinth flour substitution in feed (P1), 10% fermented water hyacinth flour substitution in feed (P2), water hyacinth flour substitution fermented 15% in feed (P3). Feed is given at satiation three times a day. The test parameters observed were the quality of the feed produced and the feed conversion ratio of the seeds of bileh fish (Rasbora sp.). The results showed that applying water hyacinth flour (Eichhornia crassipes) on artificial feed gave the same response to the quality of the feed produced but had a significant effect on the feed conversion ratio for bileh fish. The lowest (best) feed conversion ratio was obtained in the P3 treatment.Keywords: feed quality; feed conversion ratio; hyacinth flour; Rasbora sp.","PeriodicalId":431784,"journal":{"name":"Acta Aquatica: Aquatic Sciences Journal","volume":" 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138615747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This river exhibits a mixed tidal regime with a tendency towards a double daily tide, which can cause sedimentation. Monitoring of this sedimentation can be conducted using remote sensing methods. The aim of this research is to analyze the concentration of suspended sediments based on direct measurements and appropriate algorithm processing. The data processing results from satellite images in 2022 using the Budhiman, Nurandani, and Lestari algorithms have a similar range of values to the direct measurements, ranging from 72 mg/L to 84 mg/L, although there are some data points that fall outside this range. However, the Budhiman algorithm demonstrates the best correlation with the direct measurements. The processed satellite data shows fluctuating values, indicating fluctuations in suspended sediment concentrations. Based on the conducted research, it is evident that the distribution pattern of suspended sediments in a river system can be analyzed using remote sensing techniques.Keywords: Remote Sensing; Suspended Sediment; Watershed","PeriodicalId":431784,"journal":{"name":"Acta Aquatica: Aquatic Sciences Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122580458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
