ABSTRACTThe fish catches of fishermen was strongly influenced by wind, temperature and rainfall. This research was conducted in December 2018 – February 2019 in the Barelang Fishing Port Batam City. The purpose of this research are to know the patterns of changes in wind, temperature and rainfall that occur in Batam City and the influenced on fishermen fish catches in Batam City and to determine the good time/season for fishing operations. The research used survey method, primary data obtained using questionnaires and secondary data obtained from Barelang Fishing Port, BMKG Hang Nadim amd Batam City Fisheries Service. The hypothesis was tested using a simple regression test. Wind, temperature and rainfall data were analyzed using Microsoft Excel 2010. The results showed that the relationship between wind speed with fishermen fish catches is opposite each other, temperature with fishermen fish catches is directly proportional and intensity of rainfall with fishermen fish catches is opposite each other. The good season to catch fishing is in the transisition season 2 (October to November) and transition 1 (March to May). Analysis of climate change trends in Batam City shows that the average of wind speed tends to decrease every year, the average of temperature tends to increase every year and intensity of rainfall tends to decrease every year.

Abstract Teluk Pambang Village in Bengkalis Regency which is located in the Riau Province is one of the villages that is very vulnerable to abrasion, because it is an area that faces the Malacca Strait and has a peat texture. This study examined how much the abrasion rate and the extent of the shoreline changes that occurred in Teluk Pambang Village by using Landsat satellite imagery data in the last 20 years. Landsat satellite image data processing consists of geometric calibration, image cutting, image sharpening and digitization so that the coastline position for each data year is obtained. Changes in the coastline from year to year are analyzed by the process of overlapping data for a certain period of time. The results of this study indicate that Teluk Pambang Village experiences abrasion with varying levels of abrasion. changes in coastline Teluk Pambang Village The last 20 years from 1997 - 2017 there was an abrasion of 4.18 m / year and sedimentation of 5.33 m / year. The change of coastline in Teluk Pambang Village is abrasion of 418.88 m and sedimentation area of 218.28 m. There is a positive relationship of current velocity with abrasion velocity and abrasion velocity relationship with wave energy obtained from linear regression results on the graph.Critical beaches that experience maximum abrasion rates are recommended to be immediately addressed so that abrasion does not continue in subsequent years.Keywords: Abrasion, Accretion, Landsat Image, Coastline, TelukPambang Village

Abstract This research was conducted in July on Pasir Jambak beach and processing wave and flow data in August at the Office of the Meteorology and Geophysics Agency (BMKG) Center in DKI Jakarta This study aims to wave and flow using Windwaves 0.5 software and the effect on abrasion and accretion caused by ocean waves and currents. From the results of the study it can be seen that the wave height at tide is 2 m and at low tide is 1 m in July 2018. The waters of Pasir Jambak beach have tidal patterns 2 times and 2 times recede. First tide at 05.00-13.00 WIB, first recedes at 13.00-19.00 WIB, second tide is at 19.00-23.00 WIB, and second tide is at 23.00-05.00 WIB. Meanwhile, the current speed reaches 16cm / s at station I. At station II the current speed is 12 cm / s, and at station III 10 cm / s. As a result of high waves can cause the waters to experience abrasion and accretion Keyword: Mapping, Wave, Current, Jambak Sand Beaches, Abrasion, Acceretion

ABSTRACT Beach is a geographical which is be composed of sand and is located in the coastal area. The coastal area is the restrictions between coastal and sea. Beaches can change due to natural and human influences. The research was conducted in July 2018 at Tapian Nauli I, Central Tapanuli Regency, North Sumatera Province.The aim this research is to map and analyze the rate of shoreline change using Landsat Imagery. Imagery data downloaded from USGS site and then to analyze using ER Mapper and Arc Gis application.The results show that there has been a change in the coastline (abrasion and accretion). The current velocity range 0.09 - 0.12 m/s. The lowest of wave energy is 1.568 Nm / m² and the highest is 5.096 Nm/m². The lowest of abrasion is 0.538 m/year and the highest is 3.36 m/year.

ABSTRACT The level of electricity usage needs continues to increase each year in line with increased economic growth. One of the technologies used in producing electricity is the PLTU (Thermal Power Station) where PLTU Teluk Sirih is the first PLTU in West Sumatra that has been operating since 2013 and has a capacity of 2x112 MW. The existence of a power plant in the waters of Sirih Bay is thought to affect the characteristics of these waters. This is because besides producing electricity, it also produces hot water waste from the process of absorbing hot steam that enters the coastal waters through the outlet channel. The purpose of this study was to determine the distribution process of hot water waste from PLTU Teluk Sirih at high tide and ebb with field data and hydrodynamic modeling of waters, as well as sea surface temperature observation data at 16 sampling points. Verification of field data and hydrodynamic models has a Root Mean Square Error (RMSE) value of 5.74% (e = 0.015). The pattern of ocean circulation in the waters of the Sirih Bay Coast is mainly controlled by the tidal force, where the flow pattern at the time of the tides goes northeast with some moving towards the southwest. Observations show the temperature of the waste of hot water in the outlets until the sea in front of them is recorded between 32 °c to 35 °c. Horizontally, the delusional zone of the waste heat reaches a radius of 500 m from the mouth of the outlet where the waste heat occurs more broadly during low tide conditions.

The research was conducted on February – March 2020 and located in Pandan Island with using survey method. The research aimed to analyze characteristic habitat of the physical and biological turtle nesting beaches, the distribution of turtle’s nests, and the microbial conditions of the turtle’s nests. The result showed that the length of beach was 1,379.4 m with average width of beach was 16.13 m. The average beach slope was 5.52 %. Substrate type dominated by sand substrate. The most abundant vegetation was ketapang tree (Terminalia catappa) and the predators discovered were monitor lizard and dog. There where 4 turtle nests were found, which was 3 nests of hawksbill turtles and 1 nest of green turtle. The average distance of nests from high tide line was 5.7 m with average distance between nest was 177.87 m. Respectively, the average of temperature, humidity, and depth of the nests were 29.58℃, 12.78%, and 53.3 cm. The average size of curve carapace length was 84.25 cm and average curve carapace width was 76.25 cm. The average number of eggs was 144 of each nest with average diameter of eggs was 3.35 cm.

ABSTRACT This research was conducted in January 2019, the sample was collected from the coastal waters of Sungai Pakning, Bengkalis Regency, Riau Province. This study aims to analysis content of organic sediments and abundance of macrozoobenthos, then the relationship between the content of organic matter and the abundance of macrozoobenthos in the waters of the Sungai Pakning. The method used in the research is the survey method. The range of organic matter in the waters of the Sungai Pakning is 6,73%-12,76% and the abundance of the average macrozoobenthos is 11,85 ind/m2-17,78 ind/m2 with the dominant species being Anadara granosa. The influence of organic matter content on macrozoobenthos abundance has a coefficient determination (R2) of 0,406 which means that the influence of organic matter in the waters of the Sungai Pakning is 40,60% while 59,40% is influenced by other factors. This is because the mangrove vegetation contributes greatly to organic matter.Keywords: Sungai Pakning, Sediment Organic Matter, Macrozoobenthos, Anadara granosa, Mangrove vegetation.
