“…Coral reefs do not live in waters that receive regular freshwater runoff from large rivers, which leads to low salinity (Anonymous, 2019). These factors play an important role in the continuity of the photosynthetic process by zooxanthellae found in Pollution from the mainland will instantly change the quality of water so that it can damage the reef coral (Wibawa and Luthfi, 2017).…”

Coral reefs currently are suffered from natural factors along with increasing anthropogenic activity. Panjang Island, a small reef island located in Jepara Regency, may also be experiencing such conditions. Therefore, this work was aimed to observe the condition of the coral cover of Panjang Island. Line intercept transect was applied to survey the coral cover and mortality index from fourteen stations. Insitu data consisted of the bottom substrate composition of the reefs and the physical parameters of the sea. The secondary data, i.e. coral reef area maps from 2001 to 2019 were taken from Landsat Image 7 and 8, data of wind were obtained from www.ogimet.com, while tidal data were collected from BMKG. The bathymetry was determined from the Geospatial Information Agency data, salinity global analysis forecast Phy 001.024 (CMEMS). Sea surface temperature (SST), and chlorophyll-a distribution were analyzed using ENVI software. The result showed that Panjang Island has a poor to the moderate condition of hard coral. Two out of six categories of abiotic and dead coral were found to be high. The mortality index of coral was in the high category (average 0.52). During research periods the sea waters were characterized by high sea surface temperature (29.34-30.94°C), chlorophyll-a was also tended to be high (0-2.65 mg.m-3), and an average of salinity was high 32 ‰. The weak currents came to all sides of the island, therefore the coral reef was not exposed to extreme currents. The waves came from the east, then the energy decreases after being blocked by coral reefs on the eastern side of the island, so that coral reefs in the northeast and south sides were safer to be exposed. The results suggest that hydrodynamic ecology directly or indirectly affected the percentage of coral cover and mortality index at the reefs of Panjang Island.

“…[6] • The cause of coral reef damage is land use [7] • Nature (sedimentation), anthropogenic activity (building of Nusantara Fisheries Port), adjacent human activities, and unconnected tourism activities. [8] • Pests, weeds, pollution, and habitat conversion. [9] • Society, economy, demography, technology, politics and culture, logging, land clearing, agricultural expansion, urbanization, infrastructure, mining, hydrological changes, salinization, soil type, climate and topography, geographical variables such as proximity to population centers and infrastructure, including roads, irrigation systems, extractive activities, transformation with urbanization, expansion of infrastructure, spread of invasive plants and animals, and extractive land such as agriculture, grazing, logging, mining, and land use.…”

Coral reef ecosystems provide many ecological, economic, and social benefits. Despite their numerous functions, coral reefs are in a vulnerable state due to the effects of human activities. The condition of coral reefs has decreased in many parts of the world. Therefore, coral reef examinations need to be carried out continuously in order to formulate management strategies that can reduce their vulnerability over time. This study aims to analyze the vulnerability index of coral reefs, the sensitivity of coral reefs to the causes of vulnerability, and the adaptive capacity to anticipate vulnerability. The primary data are the perceptions of respondents’ who filled out a prepared questionnaire which included eight dimensions: information on the environmental conditions, fishing ports, fishing areas, coastline settlements, tourism management, tourism attractions, socio-economic conditions and population, and aquaculture. The data were analyzed using multidimensional scaling (MDS). The results of the analysis revealed that fishing ports, fishing areas, and environmental condition are high vulnerability indexes which cause damage to coral reefs. The highest coral reef vulnerability sensitivity was found to be triggered by the distance from fishing areas and the distance from fishing vessel channels. An inverse relationship between vulnerability and adaptive capacity was shown. Hence distance from fishing areas and distance from fishing vessel channels are the attributes that have low adaptive capacity.

Maharatu Village, Marpoyan Damai District in Pekanbaru City has the potential for agricultural land, namely secondary crops. These agricultural activities can have an impact on groundwater pollution, this is due to the use of fertilizers on agricultural land which can seep into the underground water system. This study aims to determine water quality based on parameters of PH, COD, BOD, TDS, coli bacteria, turbidity, Fe, Mn, and Pb and to determine soil characteristics based on porosity and permeability. Water and soil samples were collected from Jalan Kartama, Maharatu Village, Marpoyan Damai District, Pekanbaru City. Water samples were taken from one source and soil samples were taken from 5 observation points representing agricultural land at a depth of 10 cm. Analysis of water quality and soil characteristics is descriptive analytic, while the relationship between porosity and permeability characteristics is analyzed by means of correlation analysis. The results showed that the water quality for all parameters was good except for the pH parameter which was 3.86 and acidic. Soil characteristics show that the largest porosity value is 38.26% and the smallest porosity value is 22.0%, while the maximum soil permeability value is 9.93 cm / hour and the minimum soil permeability is 1.22 cm/hour. Both data show that the relationship between permeability and porosity is directly proportional, the greater the permeability, the greater the porosity value.
