Abstract

The Kaliyasa River was one of the many rivers in Cilacap Country. The River Kaliyasa is physically close to populations and industries that produce a wide range of products, making it a great potential for receiving both domestic and industrial wastes. The study was carried out in Oktober-November 2020 with four sample viewing points before the wastewater output, the wastewater outlet, at exactly the time of the wastewater output, and after the wastewater output. The sampling was done three times every two weeks. Based on this study, calculations indicate that the average value of the pollution load from the wastewater outlet was staggering at 32.661,60 kg/day. The average price of the pollution burden from the station after the wastewater output was produced a value of 15.945,92 kg/day. Average TSS, DO, BOD, and COD variables have already surpassed the second of class river quality. The Kaliyasa River pollution index is obtained that according to TSS, DO, BOD, and COD variables measured indicate IP Numbers in level 6, which include 6,16 of moderate pollutants. Keywords: Comparisons with Water Quality, Load Of River Pollution, Pollution Index

Abstract

Spacing is one of the technical factors that affect the growth of Sargassum sp. because of its relationship with the absorption of interrelated nutrients. Differences in spacing in the cultivation of Sargassum sp. has a function to find out what distance between plants is the most appropriate so that the growth of Sargassum sp. more optimum. This is closely related to the competition of each seaweed for nutrients as food. Spacing is one of the technical factors that affect the growth of Sargassum sp. because of its relationship with the absorption of interrelated nutrients. The purpose of this study was to determine the effect of different spacing on the growth of Sargassum sp. with the basic peg method. This research was conducted in November-December 2020 in the waters of Labuhan Ijuk village, Moyo Hilir sub-district, Sumbawa Regency using an experimental method with a completely randomized design (RAL) with a maintenance period of 30 days. The results of this study showed the growth of Sargassum sp. the highest was in treatment P0 (spacing 30 cm) with an average absolute growth of 159 grams, specific growth of 3.16%, followed by P1 treatment (25 cm spacing control) with an average absolute growth of 124 grams, specific growth was 2.16% then followed by P2 treatment (20 cm spacing) with an absolute growth rate of 103 grams, specific growth averaging 2.35% and then the lowest was obtained in treatment P3 with a spacing of 15 cm with an average absolute growth value of 65 grams, specific growth 1.64% with an initial planting weight of 100 grams. Keywords: Seaweed, macro algae, aquaculture, brown algae, alginat.

Abstract

ABSTRACTThe reef fish community is a very important part of the coral reef ecosystem, both in terms of economy and ecology. The purpose of this study was to determine the structure of the reef fish community, including species composition, abundance and ecological index of reef fish based on their role (major, target and indicator) in the coral reef transplant area of Kapoposang Island. The research method used is the coral reef fish visual census method to determine the structure of the reef fish community. Observations were made only once with two transect withdrawals and two repetitions on each transect. The results of the observation of reef fish, overall found 48 species, 28 genera, and 15 families consisting of major, target and indicator fish categories. The highest species composition came from the major fish category, chromis viridis, 16.7% and 12.7%, while the lowest species composition came from fistularia commersonii, parepercis hexophtalma, cheilinus fasciatus, chaetodon kleinii, chaetodon collare with the same species composition value of 0.21% - 0.42% other species have a species composition ranging from 0.63% - 8.46 %. The largest abundance of fish came from the pomacentridae family with a value of 560 ind/400m² while the lowest fish abundance was 2 ind/400m² from the fistularidae and pingupidae families. The diversity index value is 3.2621 including the high diversity category, the uniformity index value is 0.8427 including the stable uniformity category, and the dominance index value is 0.0574 including the low dominance category.Keywords : Kapoposang Island, Community structure of reef fish, Transplantation of coral reef

Abstract

AbstractThe existence of alpheid shrimp species in Indonesia is not too much found in the latest scientific publications. Alpheid shrimp species can be used as an indicator to assess the quality of the environment in mangrove areas. The discovery of shrimp species from the Alpheid group adds to the list of biodiversity in the mangrove area of Kuala Langsa. Biodiversity of a high number of species in this group of shrimp is usually found in mangrove areas with muddy sand beaches. This is because, this type of shrimp has a habit of living in muddy areas. The living zone of this type of shrimp is almost the same location as the type of crab that is wrapped like the Scylla serrata group. Mangrove area kuala langsa although it has mangrove biodiversity that is relatively high. Kuala Langsa mangrove forests are dominated by the Rhizoporaceae group, which is a type of vegetation that is effective as a sediment trap from the direction of the river estuary while holding abrasion from the direction of the sea. In the current year there is also a condition of decrease in the number of large trees. This is caused by the harvest of mangrove wood to produce charcoal for fuel purposes. This condition will slowly make the function of the ecosystem decrease. Where the role of ecosystems provide living niches for aquatic organisms is decreasing. Land clearing of certain areas of the mangrove area for physical infrastructure purposes such as the construction of restaurants, settlements, roads, small aircraft runways, reduces the ability of the region to maintain the function of its ecosystem. The next thing is the ecological pressure for aquatic biota that has living niches in mangrove areas.Keyword: alpheid shrimp, alpheus, mangrove, ecosystem, kuala langsa, aceh
