Marine pollution results in a decrease in the quality and quantity of coastal and marine resources. Most of the people in tambak sub-district have a livelihood as fishermen and work in the field of fish processing industry and seafood trade and the location of the waters are often passed by industrial vessels. This resulted in increased ship activity in the waters of Labuhan Beach, Tambak District, Tanjungori Village. As the activity increases it causes marine pollution. One of the sources of pollution produced is oil spills from former fuel boats or ships that cross the area of the water. This method can provide information about the condition of the waters according to their designation. The purpose of this study is to know the water quality based on the parameters of temperature, pH, salinity and brightness and know how much oil content in the waters of Labuhan Beach, Bawean Island. Sea water sampling was conducted at 4 stations, then the results were compared with sea water quality standards for biota based on KEPMEN LH No.51 Year 2004. The results showed that the oil content ranged from 0.0016%–0.0377%. As for the pH parameter, salinity and brightness in accordance with the quality standard, for the temperature parameter exceeds the standard value of quality. Based on this study, pollution index calculations show that the waters of Labuhan Beach, Bawean Island are in the category of lightly polluted.

Pasir Putih Waters Situbondo has beautiful coral reefs and is often used for diving activities. Due to the large amount of coral damage caused by the activities of tourists or divers, coral transplants were carried out in these waters. The Diving UKM of Hang Tuah University has carried out coral transplantation using the bioreeftek method and the shelf and substrate method while the community has carried out coral transplantation using the rack, net and substrate method. This study aimed to determine the effect of the coral transplantation method on the survival rate of corals. The data collection locations were divided into three stations with different transplantation methods, namely station 1 (bioreeftek method) and station 2 (shelf and substrate method). This research method used descriptive analysis to determine the relationship between coral transplantation method with coral survival rates and to determine the relationship between oceanographic parameters and coral survival rates. The results showed that the survival rate of corals at station 1 were 56%, station 2 was 89%, station 3 was 20%. They showed that the coral survival rate at station 2 with the shelf and substrate method had better results. The method had high shelf legs to avoid stirring the bottom of the waters by currents or waves so that the sediment did not reach the bottom of the shelf and made of iron, which is stronger and stronger.

The variability of temperature, salinity and rainfall in the Indonesian region is strongly influenced by the El Niño-Southern Oscillation (ENSO) phenomenon so that this study aims to describe the characteristics of the ENSO phenomenon, compare and analyze the characteristics of temperature, salinity and rainfall under normal conditions and changes due to the ENSO phenomenon in the Madura Strait. This study used a descriptive method by collecting data using secondary data and making a description of the observed phenomenon. Data required for 12 years from 2010-2021. The results showed that the variability of temperature measured during the 2010-2021 period showed the highest temperature values were in the closed waters of the Madura Strait with an average of 28.64°C and the lowest were in the central waters with an average value of 28.59°C. The highest rainfall value is in closed waters with an average of 6.06 mm and the lowest is in central waters with an average value of 5.562 mm. The highest salinity is in open water with an average value of 32.06 ppt while the lowest salinity is in closed water with an average of 31.42 ppt. The highest temperature and rainfall are generally found when the La Niña phenomenon is taking place, while the lowestntemperature and rainfall are found during the El Niño phenomenon. The highest salinity is generally found during the El Niño phenomenon, while the lowest salinity occurs during the La Niña phenomenon.

Hydro-Oceanographic Parameters are the main factor in supporting the development and periodic maintenance of a port. The research was conducted in November 2021. The data in the study were obtained from observations in the field. The data used in this research is in the form of tidal data and tidal currents. Based on the results of data processing for 1 month in November 2021, the Muncar waters have a mixed tide prevailing semi-diurnal type. The highest tide value during November occurred on November 17 2021 at 22:00 WIB with a water level of 2.6 m and the lowest tide occurred on November 18 2021 at 05:00 WIB with a water level of 0.4 m. Currents move from the Bali Strait towards the Indian Ocean. Just before high tide, the tidal currents move from east to west (entering the anchor pond) with a speed of 0.40 – 0.64 m/s. At low tide, the current moves from West to East (leaving the anchor pond) with a speed of 0.42 – 0.58 m/s.

The variability of rainfall in the Indonesian region is strongly influenced by the ENSO and IOD phenomenon. The purpose of this study is to describe the characteristics of the ENSO and IOD phenomena over a period of 31 years, compare the characteristics of rainfall under normal conditions and characteristics due to ENSO and IOD phenomenon, and analyze the monsoon rain area (Lampung, Surabaya, Jayapura) which are more influenced by ENSO and IOD phenomenon. The results showed that in the first decade to the second decade the incidence of La Niña decreased by 3.4% and then increased in the last decade by 4.3%, as the dominant La Niña incidence in weak intensity has increased every decade. At the time of the IOD phenomenon in the first decade to the second decade there was an increase in Positive IOD of 15.2% and then an increase which tends to be drastic in the last decade by 27.2%. In the Lampung and Surabaya areas, when El Niño and Positive IOD occur, the beginning of the rainy season tended to come later, meaning the dry season was longer, which occurred from May to November. When La Niña and Negative IOD occurred, the rainy season began earlier in June to November and experiences the rainy season throughout the year. In the Jayapura area, rainfall tended to occur throughout the year during the ENSO and IOD phenomena. The influence caused

Popoh Waters has a bay that contains a fishing boat port, a Fish Auction Place (TPI), and a Fishing Port (PPI). Indonesia has many cases of fishing boat accidents caused by bad weather. It is important to know maritime weather information to minimize fishing boat accidents. This study aims to identify the characteristics of wind, rainfall, sea waves in each season, identify the seasons that are dangerous for fishing boats and their effects on fishermen's catches. The results of the processing showed that Popoh waters had wind characteristics with a category that can endanger fishing boats in the East season with a top speed of 8.41 m/s. The characteristic of rainfall which had the highest rainfall was the West monsoon with the highest intensity of 87 mm. The characteristics of the waves in Popoh waters had waves that could endanger the sailing of fishing boats in the East season with the highest wave condition of 1.93 m.
