This study aims to determine the current condition of groundwater quality in the city of Magelang due to the disposal of domestic and industrial waste. The analysis used was to measure physical, chemical, and biological parameters in situ and ex-situ. The research method used purposive sampling and then analyzed descriptively using water quality standards. The results showed that the physical parameters were still in good condition, while the values (TSS) of Total Suspended Solid and Total Dissolved Solid was 3.7 mg / L and 227.95 mg / L. On the other hand, there was a fluctuation in the pH value at several water stations which showed a tendency to be acidic. Furthermore, the nitrate levels at research stations 1,6,7 and 9 showed values that exceeded the established threshold of 10 mg/L. Furthermore, for the BOD value that has a value of more than 2 mg / L as a requirement for entering class 1, groundwater quality is safe for hygienic, Chemical Oxygen Demand has a value that exceeds the maximum requirement of 10 mg/L in all research station and is categorized as heavy pollution. The total coliform value that exceeds the water quality standard for sanitation hygiene according to Permenkes No. 32 of 2017 at 50 MPN / 100ml. The quality of groundwater in the Magelang can be used for drinking water, provided that its use must go through the cooking process first.Keywords: Groundwater quality, waste, Magelang

Parasite infections in aquaculture can trigger primary infections due to decreased fish immunity making it easier for other microorganisms, both bacteria and viruses, to enter the fish's body. This study aims to identify, calculate the prevalence and intensity of parasites that found in catfish ponds of the "Mino Ngremboko" fish farmers group in Grabag Village, Grabag District, Purworejo Regency. This study used the scraping method by reviewing the gills, mucus from the skin, fins and digestive tract onto a glass object which was then observed microscopically using a light microscope with a magnification of 10-40x. The parasites found were ectoparasites consisting of 6 species; Trichodina sp., Tetrahymena sp., Gyrodactylus sp., Epistylis sp., and Dactylogyrus sp. No parasites were found from the endoparasite and hematozoa groups. The highest prevalence was Dactylogyrus sp. with a prevalence rate of 54% and the lowest was Dinoflagella with a prevalence rate of 10%. The highest and lowest parasite intensities were Epistylis sp. (18,0 ind./infected fish) and Dactylogyrus sp. (2,8 ind./infected fish), respectively. It can be concluded that the level of parasitic infections in the fish farmer groups ponds was at the "common-usually” level based on William and Bunkley's prevalence criteria.Key words: Clarias sp., identification of Parasite, prevalence, intensity, Mino Ngremboko

The study of biodiversity is important in looking at the current condition of an aquatic environment. The purpose of this study is to examine the biodiversity of the fauna in the Progo River in determining the level of fish diversity and the status of fish resources in the Progo river by using a Geographical Information System (GIS). The sampling method was carried out by purposive sampling consisting of 17 stations. The data taken includes coordinate points, the diversity index (H '), evenness index (E), dominance index (D), and relative abundance (Kr), as well as making a map of the distribution of progo river fish using Arcgis software version 10.5. The results showed that the diversity index value (H ') was moderate to high with a value range of 2.24 to 3.83, with a catch composition consisting of 23 species and 11 families. The evenness index value (E) of the progo river ranges from 0.71 to 1.21. Based on this value, the Progo River has an evenness value between species that is relatively even or the number of individuals of each species is relatively the same. Progo river dominance index value ranges from 0.002-0.008, that is, no fish species dominates. The highest relative abundance (Kr) was balar fish (Barbonymus balleroides) = 0.12%, melem fish (Osteochilus vittatus) = 0.11%, uceng fish (Nemacheilus fasciatus) 0.09%, tilapia fish (Oreochromis niloticus) 0 , 08%, while the lowest was kekel fish (Glyptothorax platypogon) and sepat fish (Trichopodus trichopterus) with a value of 0.01%. The results of the analysis of the distribution of fish in the Progo river show that the fish are widely distributed in the river area which has deep and calm water characteristics, this is indicated by the number of catches at each research station.Keywords: Biodiversity, Progo River, Geographical Information System (GIS)

The high demand of shark products, particularly fins, have influenced the increase in the exploitation and trade of sharks, included small scale fisheries. The condition can increase the vulnerability of sharks because of their biological cycle and as a top predator and economically important fish. This paper aims to identify the conditions of exploitation and management of sharks in Sumenep Regency. The method used in this research is the field observation, in-depth interview and review of policies. Based on the existing results indicate that over exploitation has occurred in Sumenep, where fishermen catch almost any size of sharks, both great until the baby sharks ('baby hiu’) in large numbers. Several species of sharks that many caught are the species Carcharhinus melanopterus, C. obscurus, Sphyrna lewini and Chiloscyllium punctatum. Shark trade activities occur in Tempat Pelelangan Ikan (TPI) of Pasongsongan, the fishing port of Ambunten, Dasuk, Dungkek, and Tanjung–Saronggi. Currently, the regulations governing the management and protection of sharks in Indonesia is still limited to only a few species of sharks, including whale sharks (Rhincodon typus), shark saws (Pristis Microdon, P. clavata, P. zijsron, and Anoxypritis cuspidata), and manta rays (Manta birostris and M. Alfredi), although other species has status Near Threatened until Endengered based International Union for Conservation of Nature (IUCN) and Appendix II based on the Convention on International Trade in Endangered species (CITES). Not to socialized existing regulations to the fishermen, the absence of regional policy in particular, and the high price is one reason still rampant shark fishing on a large scale. To that end, public awareness activities to fishermen and communities and appropriate regulation is needed in sustainable shark management efforts.

Fillet is one type of ready-to-eat frozen food product. Fillet is made from ground meat, given spices, and a binder mixture, then cured, steamed, cut, and covered with flour adhesive (dough) and bread flour (breading). Field Work Practice is to study and learn workers' personal hygiene in producing Fillets of dumbo catfish (Clarias gariepenus) at P2MKP Karya Lestari, Pamekasan. This Riset Activity uses the descriptive observative method, which is a method of solving a problem by describing and explaining the situation and condition of an object of observation based on direct observations and facts that occur in the field. Collection in this Risetactivity uses primary collection methods from interviews, active participation, observations, and secondary through literature study. The application of personal hygiene in P2MKP has been carried out well by standards, including using closed clothing, using gloves according to standards, maintaining the health and safety of workers, and prohibiting the use of personal equipment made of metal. But the knowledge of personal hygiene workers is not evenly distributed because some workers have yet to receive training facilities on personal hygiene, which is an obstacle in applying personal hygiene to workers
