This study aims to determine the effect of water hyacinth (Eichhornia crassipes) powder application on artificial feed on feed quality and feed conversion ratio for bileh fish (Rasbora sp.) fry. 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.

In Aceh Province, tiger prawns (Penaeus monodon) are one of the main commodities of farmers for cultivation. Feed is one of the factors that can support the development of tiger prawn culture. The quality feed is feed that contains essential nutrients in sufficient quantities, one of which is protein. This study aims to determine the effect of commercial feed with different protein content on the growth and survival of tiger prawn fry. This study used a completely randomized design (CRD) method consisting of 3 treatments and 4 repetitions, namely P1 (using 40% protein feed), P2 (using 35% protein feed), and P3 (using 26% protein feed). The results showed that commercial feed with different protein content had an effect on active weight growth and feed conversion ratio, but had no effect on tiger prawn survival. Furthermore, the best protein content for the growth and survival of tiger prawn was obtained, namely 40%.Keywords: commercial feed; growth; protein; survival rate; tiger prawn.

The Sambas River is part of the watershed of Sambas River which covers 71.03% of the total area of Sambas Regency. 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

Research on calcium minerals that are effective and safe for health and the environment is being developed. These studies aim to find natural ingredients that contain high mineral levels, study effective methods, and study the characteristics of calcium obtained. Natural calcium is interesting to develop because it comes from renewable natural resources such as those fishery wastes. This article contains a study of the potential of fish bones, shellfish shells, and crustacean shells as natural sources of calcium and methods of manufacture. Oyster shells that are crushed at 900°C for 2 hours will produce Ca2+ levels of 56.77% while calcination for 4 hours produces Ca2+ = 86.22%. direct shells calcined at 900°C; 4 hours yields Ca2+= 77.15%. The yield produced with a calcination time of ≥ 4 hours is relatively stable, which is 55 -57 %.Keywords: Calcium; Clam shells; crustacean shells; fish bones

Tilapia (Oreochromis niloticus) is a fish that is widely consumed by people in Indonesia. Market demand for tilapia increases every year, so tilapia production needs to be increased, especially in the process of rearing tilapia. This activity aims to determine the technique of rearing tilapia in swift water ponds on growth and survival. This activity is carried out from December 2021 to January 2022 at the Bedegung Fish Seed Center, Muara Enim. The method used in this activity is field observation and collection of primary and secondary data. The stages of implementing the activities include pond preparation, seed selection, seed stocking, fish rearing, and harvesting. The parameters observed were growth, feed efficiency, survival, and water quality. The results obtained were a growth in absolute weight of tilapia by 4.79 g; an absolute length of 6.5 cm; a feed efficiency of 74.24%; and survival of 94.93%. While the water quality values are temperature 23.1-25.8oC and pH 7.55-9.12.Keywords: Tilapia; Rearing; Swift water pons
