Indonesia's environmental services and natural resources have great potential both on land and sea, especially for tourism purposes. One of the tourism sectors comes from coastal tourism. The development of coastal tourism areas must lead to a planned development in a comprehensive manner so that optimal benefits can be obtained for the community. The research was conducted in Labuhan village which is one of the coastal villages in Lamongan Regency. The method used was survey and observation methods coupled with closed interviews with questionnaires, while natural parameters were carried out by field observation. The research aims to analyze, choose the right type of tourism activity according to the suitability index of the type of tourism activity on Kutang beach, Labuhan village, Brondong District, Lamongan Regency. Data analysis was done by means of multi criteria analysis. This analysis is developed based on utility theory, with the assumption that a person's total (composite) utility is formed as an aggregate of the many attributes (components) that make up the utility. The type of tourism activity which is categorized as very suitable or feasible to do in the Kutang beach area is in the form of tracking activities with a suitability value of 84% and Safari Photo of 83%. Alternative types of activities (according to condition) are Canoeing with a suitability value of 80%, fishing and culinary 77% and swinging 74%.

Freshwater fish has an important role in fulfilling an affordable source of animal protein, especially for areas that have limited access to fish from sea catches. Tilapia fish (Oreochromis niloticus) is one type of freshwater fish that is popular and generally consumed by many people. This study was conducted to determine the effect of community interest in the Kotabumi area, North Lampung Regency on tilapia fish that are maintained in different habitats, namely naturally grown in Lake Ranau, West Lampung Regency, and artificially in the enlargement pond owned by the community in Kotabumi area. Based on the results of the available data, it is concluded that fish habitat has an effect on people's consumption interest. Tilapia fish originating from Lake Ranau are more attractive to the community when compared to local tilapia fish that are kept in community ponds in the Kotabumi area. The organoleptic test value of fresh tilapia originating from Lake Ranau has a higher value of 7,84 ≤ µ ≤ 8,28, compared to tilapia fish from community ponds with a value of 7,52 ≤ µ ≤ 7,55

The water quality analysis activities carried out by smallholder farmers with the construction of cement walls and cement pond bases on the Konang beach, Panggul District, Trenggalek Regency, have not met the standard standards in the analysis of pond water quality. Pond farmers only analyze the pH, brightness and temperature of the pond water. The research objective was to obtain information and describe the analysis of water quality in the community pond construction of cement walls and the bottom of cement ponds at Konang beach, Panggul District, Trenggalek Regency. The activity of analyzing the water quality of the community plots of construction of cement walls and the bottom of the cement ponds on the Konang beach, Panggul District, Trenggalek Regency, was observed in the form of temperature, brightness and pH, with a pond area of 250 m2. Water quality observation activities for 30 days, in one day water quality observations are made twice, namely in the morning and evening. The pH measurement results were obtained, ranging from 7.4 to 8.5, so that the results of measuring the pH of the water in the people's ponds in Koneng Beach were still normal or normal. According to Boyd (2001) in Andi S and Sahabuddin (2014), it is said that water organisms (fish or shrimp) require a pH range of 6.8 - 8.5. the results of measuring the brightness with a simple tool, the measurement results are between 25-40 cm. Badrudin et al (2014) stated that the optimum brightness level of pond water which is influenced by plankton density is around 20 - 40 cm. So that the level of brightness can be concluded that it is still in rational or optimal. The temperature in the ponds was 24 ᴼC - 28 ᴼC, still within normal or optimal. According to Supito (2017), the pond temperature in the range of 28 ᴼ C to 32 ᴼ C is the optimal temperature forcultivating vaname shrimp.

Tin mining activities in the Bangka Belitung Archipelago Province have led to the formation of pits that have not ideal water quality for aquatic organisms in general. Acidic pH and high metal contamination at certain age under certain causes only a few species are able to live well in these ecosystems. This study aimed to determine the identity of the pioneer fishes in ex-tin mining pit <1 year of Bangka Island through DNA barcoding based on COI gene. The pioneer fish in ex-tin mining pit <1 year were Kepala Timah fish dan Betok fish. Species determination was based on sequences similarity in NCBI and BOLD System showed that Ikan Kepala Timah had similarity with Aplocheilus panchax and its morphology indicated Ikan Kepala Timah was Aplocheilus panchax. The sequences similarity of Betok fish in NCBI and BOLD System showed that Betok fish had similarity with Anabas testudineusi and its morphology showed that Betok fish was Anabas testudineusi. The Kimua 2 Parameters (K-2P) Neighbour-Joining (NJ) clearly confirmed that Kepala Timah fish found in ex-tin mining pit <1 year was Aplocheilus panchax, whereas Betok fish was located outside clade of the group. It indicated that Betok fish was found in ex-tin mining pit <1 year can be expected as a morphotype of Anabas testudineusi that needed further confirmation in other studies, both molecularly and morphologically. The sequence data of COI gene of Betok fish found in ex-tin mining pit <1 year was expected can supported available sequence data of Anabas testudineusi in NCBI and BOLD System.

Pangasius sp. is a mainstay commodity in Indonesia. Economically Pangasius sp., is promising to be developed as an export commodity. Hatcheries of Pangasius sp. are carried out at the Marine and Fisheries Service Branch Subang. Data analysis in this research used quantitative descriptive analysis and qualitative descriptive analysis. The results of the research that Pangasius sp. can issue 323.500 eggs per broodstock with the egg weight released by each broodstock was 300 gr. The productivity of Pangasius sp. eggs can reach 5.176.000 eggs with Hatching Rate 99.6 %. The survival rate was 85 %. Analysis of the Pangasius sp. hatchery business after analyzing the R/C ratio resulted in a value of 2.9 where this business could provide a large income in a monthly cycle.

Water quality parameters play an important role in intensive pond ecosystems. The purpose of this study was to determine the relationship between of water quality parameters in intensive shrimp farming of L. vannamei. This research was carried out for 95 days of intensive shrimp farming in PT. Menjangan Mas Nusantara Company, Banten, with the physical, chemical, and microbiological parameters of water as the main reference object of observation. The results showed that during the shrimp culture period the pond water quality parameter concentration was considered to be quite optimal with a stable fluctuation trend, except for the salinity and TOM parameters whose values were above the water quality standard. Correlation test results state that between the physical chemical parameters have a strong and heterogeneous relationship, with the strongest parameters of pH, phosphate, nitrite, and TOM. As for the microbiological variables, the correlation of physical chemistry parameters of water is considered to be very weak, because from the correlation test results, only DO parameters showed the correlation with microbiological parameters. The conclusion of this study, that during intensive shrimp culture period, the physical and chemical parameters of water have a strong correlation of association between one another and the highest are pH, phosphate, nitrite, and TOM, but only dissolved oxygen parameters that show the relationship correlation with microbiological parameters.
