Pre-harvest fish mortality was often found in polyculture vannamei shrimp and milkfish in Duduksampeyan. This is thought to be caused by declining water quality. This study aims to evaluate water quality based on physico-chemical parameters and biotic index in vannamei shrimp (Litopenaeus vannamei) and milkfish (Chanos chanos) ponds. The study was carried out in February-March 2021 in Duduksampeyan using a purposive sampling method from 3 stations, vannamei shrimp ponds (station 1), milkfish ponds (station 2) and polyculture ponds (station 3) at 3 sampling points located at the inlet/outlet, middle and edge. Data analysis using ANOVA followed Tukey's test to compare data from the three stations. Correlation analysis, PCA and cluster to determine the relationship between environmental parameters and plankton. The physico-chemical parameter values were in accordance with SNI8037.1:2014 except for salinity, suspended solids at the three stations, brightness at station 3, dissolved solids at station 2. Station 1 found 8 classes with 17 genera, station 2 contained 8 classes with 11 genera and stations 3 there are 7 classes with 14 genera. The most common genera found at station 1 were Synechocystis, Spirulina, station 2 Synechocystis, Pandornia, Chaetoceros, station 3 Synechocystis, Pandornia, Spirulina. The diversity index value is between 1.7-3.1ind/L. Human activities such as settlements, livestock and agriculture are thought to be the cause of the decline in water quality from being eutrophic to hypereutrophic (TDI). The relationship between plankton and environmental parameters shows that at station 3 the optimum results are obtained to support the life of aquatic biota.Keywords: Physics-Chemistry, Diversity Index, Water Quality, PlanktonABSTRAKKematian ikan pra panen banyak dijumpai pada tambak budidaya polikultur udang vannamei dan ikan bandeng di Kecamatan Duduksampeyan.

Mangrove forest is one of the ecosystems in the coastal area that plays an important role as a habitat for iktiofauna, one of which is the gelodok fish community. The purpose of this study was to compare the community structure of mudskippers at Bahak Indah Coast, Tongas, Probolinggo with or without mangrove vegetation. The study was conducted in Januaryâ€“February 2022. The determination of the observation station was carried out purposively, which was determined based on the presence or absence of mangrove vegetation. Observation of the mudskipper community used a systematic sampling method with the help of transects and plots. The analyzed mudskipper community structure data included diversity index, uniformity index and dominance index. The results found 4 species from 2 genera of mudskipper namely Boleophthalmus pectinirostris, Boleophthalmus boddarti, Periophthalmus chrysospilos and Periophthalmodon schlosseri. Mudskipper diversity index at both stations was in the medium category, and was higher at the stations with mangrove vegetation. The uniformity index was included in the high category, and was higher at the stations with mangrove vegetation, and the dominance index was in the low category, and lower at the stations with mangrove vegetation. The results of this study indicate that the coastal waters area with mangrove vegetation contributes to the high diversity and uniformity of the mudskipper community compared to areas without mangrove vegetation.

Nile Tilapia (Oreochromis niloticus) is one of the economically important fish to be cultivated. Although tilapia is able to adapt to changes in environmental conditions, tilapia is a fish that is sensitive to pollutant exposure. Exposure to various types of pollutants has been reported to have caused death and physiological disturbances in tilapia. This study aims to analyze the effect of several water quality parameters (temperature, pH, DO, and turbidity) fed facultative pond waste water with different processing stages on the hatchability of tilapia (Oreochromis niloticus) eggs. The method used was the experimental method using RAL (completely randomized design) with 4 treatments. Each treatment consisted of 3 replications with treatment A (facultative pond water 1 with high turbidity level), treatment B (1 liter facultative pond water 4). with medium turbidity level), C treatment (1L of facultative 6 pool water with low turbidity level) and D treatment (1L of water from Ngsong Village). Data were analyzed using simple linear regression to determine the effect of water quality on hatchability of tilapia eggs and their correlation. The results of water quality obtained during observations on temperature parameters ranged from 21-27ÂºC with a pH ranging from 4.91-7.91, DO ranging from 3.52-5.65 and turbidity ranging from 1.9-0.5. Water quality parameters including temperature, pH, dissolved oxygen have different effects on the hatchability of tilapia (Orecohromis niloticus) eggs. Temperature has a significant influence on egg hatchability of 53% with a strong positive relationship. pH and DO have a small weak effect on the hatchability of tilapia (Oreochromis niloticus) eggs of 0.15 and 0.25 respectively with a weak positive relationship. Meanwhile, turbidity has a large effect, namely 73% on egg hatching, with a strong negative relationship. This means that increasing temperature, pH and dissolved oxygen tend to increase egg hatchability, while increasing turbidity will reduce the hatchability of tilapia (Oreochromis niloticus) eggs.

The use of vegetable biopesticides in plantations has long been known, but its application in forestry plant nurseries is generally still not widely practiced by the community. One of the environmental problems has become a global issue, namely the excessive use of pesticides and fertilizers. The use of pesticides that are not in the right dose, inappropriate use, inappropriate benefits and not according to the rules of use can be a source of compounds and pollution containing heavy metals which are very difficult to degrade. Cinnamon biopesticide research was carried out in several locations based on research activities. The collection of cinnamon samples was carried out in the Research Field of the Faculty of Agriculture and the manufacture of biopesticide solutions was carried out at the Forestry Laboratory, Faculty of Agriculture, Khairun University. To test the effectiveness of the biopesticide solution, it was carried out in the Ake Malamo Watershed Management Center and Protected Forest on mangrove/mangrove seedlings. The application of biopesticides is carried out by spraying all parts of the seeds with the appropriate concentration of treatment. Applications were carried out five times with an interval of once every 1 week. Observations were made every week, one day after the application of spraying. The use of fragrant cinnamon biopesticide which was sprayed on mangrove seedlings 5 times 7 days after planting with a concentration of 75% each time was proven to suppress pest attacks so as to increase their growth. This result is better than the control/other treatments.
