Abstract

The coral reef ecosystem has role as feeding and nursery ground for indicator reef fishes. Coral reef ecosystems in recent years has decline in function, globally the area of coral reefs has decline about 11%. This study aims to analyze the correlation between the condition of life coral reef with the abundance of indicators reef fish. This research was conducted in the waters of Mandrajaya (Ciletuh Geopark) with 5 stations. The method used in this research is Line Intercept Transect (LIT) and Underwater Visual Census (UVC). Data observed were the percentage of live coral and dead coral, as well as the number of indicator reef fish found. Results show that the percentage value of life coral is 51.17% dominated by the CF (Coral Foliose) category, this value shows that the condition of living coral cover is included in the good category. The obtained Mortality Index is worth 0.43 (low), this value is obtained from the ratio of life coral and dead coral. A total number of indicators reef fish is 31 individuals / 1750m² from four species, dominated by Chaetodon octofasciatus (12 individuals). Correlation between life coral cover and abundance of indicators reef fish was positive and had a sufficient relationship on both variables (r = 0.58) with a determinant coefficient of 48%.

Abstract

Red flesh fish contain in some varieties of fatty acids. One of the fish that has potential as a source of fish oil is mackerel tuna. The Fatty acid content in mackerel tuna can be used as the source of fatty acid for the human body if that component has been separated from other substances such as water or extracted from fish flesh. The method used to produce oil or fat from the materials suspected to have them is called extraction. While the way of extraction used is wet rendering. This research aims to know the characteristics of omega-3 during storage in the freezer. The Materials used in this research was Mackerel Tuna (Euthynnus affinis). This research was an experimental laboratory with three repetitions. The storage duration consisted of the zero and the thirtieth day. The parameters observed were the amount of yield, a profile of fatty acids, peroxide value, and the test of organoleptic during storage. Analysis data used variety analysis (ANOVA) and advanced test of Tukey HSD. The result data of the organoleptic test was analyzed by Kruskal Wallis test. The result showed that the yield of mackerel fish oil with wet rendering was 0,90% (w/w). There was nine profile of fatty acids consisting of SFA, MUFA, and PUFA. The omega-3 of mackerel tuna fish oil decreases during storage by 5,035% to 3,332%. The peroxide value has been increased from 13,59 meq/kg to 15,45 meq/kg. Organoleptic tests during storage decreased from 5,43 to 5,37. Storage of mackerel tuna fish oil significantly affected the content of fatty acids, peroxide value, and organoleptic value (P<0,05)

Abstract

The value of pH concentration on water quality influences the resistance or survival of kurumoi rainbow fish (Melanotaenia parva). Rainbow fish in habitat (natural) live in a pH range of 6.8-8.5 and in cultivation activities the pH range is unknown. At a concentration of pH <7 including acid pH and > 7 including a moderate pH 7 neutral pH. The direct effect of pH will affect water balance as a fish medium and will die when the pH changes extreme or changes rapidly. The aim of the study was to determine the Lethal Concentration (LC5048 hours) and Tolerance both at acidic and basic pH. The test fish used were Kurumoi rainbow fish with a total length of 2.1 ± 0.25 cm and a weight of 0.10 ± 0.05 g of ± 450 tails. There are two experiments, namely the toxicity test of LC50-48 acid pH and toxicity test of LC50-48 alkaline pH. For toxicity tests LC50-48 acid pH consisted of 7 treatments and three replications at different pH levels, namely A) pH 6.0 (control); B) pH 3.50; C) pH 3.96; D) pH 4.48; E) pH 5.07; F) pH 5.74; and G) pH 6.50. Whereas the toxicity test of LC50-48 alkaline pH consisted of 7 treatments and three replications, namely A) pH 7.0 (control); B) pH 8.5; C) pH 9.2; D) pH 9.9; E) pH 10.7; F) pH 11.6 and G) pH 12.5. The parameters observed during the study were ecording dead fish at hours to (0; 24; 48; 72 and 96) and toxicity of LC50-48. The results showed that the toxicity of LC50-48 pH to Kurumoi rainbow fish was at acidic pH of 4.70 and tolerance ranged from 5.07 to 6.50 for 96 hours while alkaline pH was 10.7 and tolerance ranged from 8.5 to 9.9 for 96 hours.

Abstract

The shrimp paste products is one of the traditionally processed products by fermentation. Shrimp paste products are familiar in every layer of society in Indonesia, which is commonly used as a flavoring dishes. A study to identify the diversity of shrimp paste products have been carried to know the home industry diversity of shrimp paste products, in Banten province as well asits physical quality. The shrimp paste products diversity was observed in the market directly and also by interview with the producer in Banten Province. The identification of shrimp paste product was conducted with physical test of filth, that was the foreign materials that mixed-up with raw shrimp paste products. The results showed that there were different raw materials used as well as the product forms, processing, physical quality of the product, pricing and marketing distribution of the shrimp paste products. Almost-uniform product of shrimp paste were found between Pandeglang (TP) and Serang (TS) shrimp paste product, while that of Domas (TD) and Binuangeun (TB) were relatively same in its diversity. Domas (TD) and Binuangeun (TB) shrimp paste product were of good quality, made of terasi shrimp, without dyes additive, and fillers. While that of Pandeglang (TP) and Serang (TS) were of low quality due to the use of waste of salted fish, dyes, and filler material.

Abstract

For a country, the existence of a coastline has an important value because it acts as a protection for marine resources and determines maritime boundaries between countries. There are various methods used for coastline analysis, both manual by digitizing and automatic by edge detection. This study compares the Normalized Difference Water Index (NDWI) method with the Sobel filter for coastline extraction in the South Coast of Sampang, Madura using Landsat 8 imagery. The best approach is then applied to the image to determine changes in coastlines from 2015 to 2020. This research shows that visually, the NDWI method produces better edges than the Sobel filter because the resulting lines are close to the original conditions in Landsat 8 or Basemap World Imagery. Sobel filter, the resulting accuracy is not very good. It does not approach field conditions, but this filter has the advantage of a relatively fast processing time because it can use a single band. Then the NDWI value generated in this study has a range of -0.497121 to 0.377046. The first class, which is a non-water body object, has a value of -0.497121 to 0. Then the second class, which is a body of water object, has a value of 0 to 0.377046. The coastline change for five years shows a shift in the coastline with a range of 0.62 to 2.75 meters. The Landsat 8 pixel size is 30 meters, while the shift is only <3 meters. So that this experiment does not show any significant coastline changes. Suggestions for further research: It is necessary to conduct a study using high-resolution imagery to confirm changes in the coastline accurately.
