Therefore, research is needed on the analysis of seawater's heavy metal contents and the spatial distribution of contamination values based on the Decree of the Minister of Environment (KEPMEN LH) No. 51/2004. This study aims at elaborating the correlation between the distribution of heavy metals (Cd, Cr+6, Pb, and Cu) in the seawater region of Bungus Bay. The data processed is data on heavy metal content from the results of sample measurements using the AAS, where the points and values of the sample analysis that have been collected using GPS at 3 location points are then imported into GIS using GIS Kriging. The value of heavy metal index for seawater based on the quality standard of KEPMEN LH No/5/2004 shows that a category does not fit, where Cd (0.0013-0.0031 mg/l), Cr+6 (0.008-0.013 mg/l), Pb (0,009-0,017 mg/l), and Cu (0.010-0.014 mg/l). The value of concentrations of these heavy metals generally shows a spatial distribution pattern different in each direction of movement. On one hand, the highest concentrations of this heavy metal are generally located in the Northwest of the bay (Cd, Cr+6, Pb) except Cu which is in the Northern part of the bay, as it is close to the discharge locations and outlet of rainwater from the catchment area. Generally, heavy metal contamination in the seawater region of Bungus Bay comes from the household, industrial, and ship loading and unloading waste. The pollution occurs as the result of the oil from transferring tankers, oil spills from fishing boats that rinse at Bungus PPS, and debris resulted from the plywood industry activity.

The area on land cover amounted to 406.61 ha in 2019, while the year 2009 amounted to 406.69 ha with a change of-0.08 ha. Mangrove conditions with an area of 79.13 ha in 2009, a decline in 2019 of 60.01 ha, a change of-19.12 ha (-24.16%). The mangrove ecosystem is getting worse because of the road construction that causes ...

Oleh karena itu, diperlukan konsep terintegrasi yang memperhatikan aspek sosial, ekonomi, dan ekologi untuk mengatasi masalah tersebut. Penelitian ini meliputi wilayah pesisir Kabupaten Pangandaran. Penelitian ini bertujuan untuk mengetahui laju Perubahan luasan greenbelt untuk mitigasi bencana tsunami yang terjadi di pesisir Kabupaten Pangandaran menggunakan data citra landsat tahun 1999, 2003, 2010 dan 2013. Metode yang digunakan dengan analisa supervised classification dengan interpretasi Citra Landsat. Hasilnya menunjukkan bahwa sejak tahun 1999 hingga 2013, kondisi greenbelt di pesisir Kabupaten Pangandaran mengalami Perubahan. Greenbelt tahun 1999 memiliki luasan sekitar 133,56 Ha dan turun sekitar 40% pada tahun 2003 menjadi hanya 81,27 Ha. Pengrusakan hutan dia...

To understand the adaptation patterns of fishermen to the impact of ecosystem changes, literature reviews, in-depth interviews, observations, and focus group discussions were conducted with local fisherman communities in the coastal region of Padang City. The results show that the fisherman community of Padang City has felt the impact of ecosystem changes such as damage to mangroves and coral reefs due to exploitation of coastal resources and natural disasters. Therefore, the adaptation of fisherman communities to cope with the impacts of changing ecosystems follows a reactive adaptation pattern. They tend to use abilities from within the community. The adaptation pattern is carried out by developing job diversification, modifying the boat fleet, adjusting fisherman times with natural signs, and tak...

The coastal region of the city stretches from Pasia Jambak beach, Muara Anai in the Northto Sungai Pisang in the South. The coast of South section is different from the coast of Northsection, because the Southern coastline is heterogeneous because there are many small bay, small islands and narrow beaches directly adjacent to the volcanic hills. This research aims to determine the dynamics condition of a coastal environment based on the characteristic (length, velocity, energy, and height), sediment transport value, accretion/abrasion factor value, and coastal equilibrium in Padang City.The method used in this study is the calculation of wavelength (L0 ), wave velocity (C), wave energy (E), run-up height (Hb ), and sediment transport (Q) to determine accretion/abrasion factor and equilibrium (G0 ). Furthermore, it is done by Geographic Information System (GIS) approach to spatial ...

The research method used is the Geographic Information System (GIS) approach using Lyzenga algorithm method with data of Landsat +ETM 7 in 1998, 2008 and Landsat OLI 8 in 2018. The results of this study indicate a decrease in the extent of coral reef conditions in 1998-2008 occurs in live coral cover covering 106.60 ha and the addition of area occurred in dead coral cover covering 147.97 ha. While the decrease of coral reefs condition in 2008-2018 occurs in dead coral cover covering 29.66 ha and the addition of area occurred in live coral cover covering 112.29 ha. Coral mortality index in Nirwana beach with an average 62.28 %, meaning very large coral deaths in this region. Coral mortality index in Cindakir estuary with an average 46.60 %, meaning quite large coral deaths in this region so that coral reefs need to be rehabilitated in these waters, which can be done in form of artificial coral transplants. The coral mortality index in Muara Dua bay average 39 %, meaning that coral mortality is quite large in this region, while the coral mortality index in Ujung Siboko bay average 44.65 %, this means quite a large number of coral deaths in this region, but this location has a very good soft coral and it is necessary to rehabilitate corals in these waters with the form of artificial coral transplants.
