Over the last few decades, surplus human activities have severely affected the marine life on the Earth’s oceans. In the past, communities around the world used the ocean for waste disposal, including the disposal of chemical and industrial wastes, radioactive wastes, trash, munitions, sewage sludge, and contaminated dredged material. Wastes were frequently dumped in coastal and ocean waters based on the assumption that marine waters had an unlimited capacity to mix and disperse wastes. Ocean pollution, also known as marine pollution, is the spreading of harmful substances such as oil, plastic, industrial and agricultural waste and chemical particles into the ocean. Increased sedimentation and the flow of nutrients and pesticides into the ecosystem affect inshore areas, causing higher algal growth, build-up of pollutants in sediments and marine species, and reduced light and smothered corals. Declines in coastal water quality have resulted in detrimental impacts on the productivity and function of tropical marine ecosystems, and ultimately on their resilience. Cumulative effect and the timing of exposure to pollutants can magnify the impacts of catchment run-off.  In order to safeguard the future of our tropical marine ecosystems, steps must be taken to prevent it from happening as a marine investment for the future.   

With reference to such situation, real-time water conditions data in Indonesia are really required. Accordingly, a group of students of the Faculty of Fisheries and Marine Sciences of Bogor Agricultural University (FPIK IPB), proposed funding support from Kelompok Program Kreativitas Mahasiswa bidang Karsa Cipta (PKM-KC Student Creativity Program for Karsa Cipta),  to implement their research program to design a real-time observation tool. The tool is called Economic Real Time Conductivity and Temperature Sensor (“ER-Contem”) initiated by Agung Tri Nugroho with his team namely Slamet Riyanto, Imam Syafi'i, and M. Sanubari. “ER-Contem” will retrieve data related to the temperature and salinity of the waters where the monitoring tool is located. The tool is very unique, as the observation data can be accessed and utilized directly through the webite by users.

International trade in food relies on a small number of key ports, straits and roads, which face increasing risks of disruption due to climate change, a report said.

Disruptions caused by weather, conflict or politics at one of those so-called "chokepoints" could limit food supplies and push up prices, the study by British think-tank Chatham House warned.

Indonesia is known to be one of the largest archipelagic nation in the world with over 17,000 islands but coastal areas have been threatened by rising sea levels with a majority of the small islands only one meter above sea level, and deforestation, reclamation and climate change continue to take place. At the coasts of Java island, over 250 households were displaced at Bedono village in Demak due to erosion over the past 20 years, and the ocean engulfs the fishing village. Villagers in Bedono witnessed the disappearance of mangrove forests and fishponds and households are cut off from land as bridges sink below sea level forcing the residents to get around by boat. According to reports, it's predicted that at least 2,000 islands could be lost by the year 2030 due to rising sea levels while 52 percent of Indonesia's 3.49 million hectares of mangrove forests are damaged, with a decline of about 200,000 hectares each year, based on the Ministry of Environment and Forestry.
