“…Marine environmental monitoring of anthropogenic radioactivity is important in Batam Water. Apart from being a global water mass transit route, the potential of Batam Water as a habitat area for seagrass (Lubis et al, 2017), benthic (Lubis et al, 2018) and fishery products (Lubis & Anurogo, 2016) needs to be ensured to be safe from the threat of radioactive pollutants. The results of monitoring the concentration of 137 Cs activity in Batam seawater are in the range of < 0.03 -0.35 ± 0.02 Bq/m 3 , while the concentration of 134Cs activity in all stations is below the (MDA) value (0.03 Bq/m 3 ).…”

A Study of the Characteristics of the 137Cs of the South China Sea in Batam Waters has been carried out. The South China Sea through several straits is connected to the Pacific Ocean region and the Indonesian Sea. The mass of Pacific water entering the South China Sea will reach Batam Waters with radioactive contaminants. Batam Waters are part of the Karimata Strait which is the Extention Line of South China Sea so that it has the potential to receive 137Cs of radioactive contaminants from operational nuclear reactors discharged in the coastal regions of China. The purpose of the study is to find out the characteristics of 137Cs and obtain the current status of 137Cs as a baseline to minimize the impact of nuclear activities on the ecosystem of the waters of Batam, Indonesia. The 137Cs characterization method uses the Ammonium Phosphomolibdate (AMP) with modification of base dissolution and measurement validation with Certified Reference Material (CRM). The results of monitoring the concentration of 137Cs in seawater in Batam waters are in the range <0.03 - 0.35 ± 0.02 Bq.m-3, while the concentration of 137Cs activity in Batam waters sediments is known to be a maximum of 0.22 ± 0.08 Bq.kg-1 with 134Cs below MDA. Result in seawater and sediments are comparable to previous research related to the presence of radiocesium in the region

Pekanbaru City, Riau Province, Indonesia located at 0°25'29.20"-0°39'15.22" N and 101°20'43.39"-101°34'25.60" E. This research aims to study the common causes of flooding in Pekanbaru city with a good geological condition. Research in the flood area of the city of Pekanbaru using primary and secondary data; geological, geomorphological, rainfall, and land use data. Information about this earth system combined with geographic information system (GIS) analysis using a small unmanned aerial vehicle (UAV) / drones including Geographic Positioning Systems (GPS) combined with online coordinate systems that can help spatial analysis to determine the level of vulnerability of flood disasters by producing a visual mapping model. The study shows that 4 locations were found vulnerable to being affected by flooding when it rained. The flood impact in those areas happened because those locations are in a geomorphological system with a low topographic area, the natural river system that controls the water to the main river, and a poor water escape-system / drainage. The geomorphological analysis showed two geomorphological units, i.e., lowland denudational and lowland structural with river flow-pattern that is dendritic, sub-dendritic, and parallel. Rainfall is quite high in 2018 with 2621.5 mm and caused flood-prone areas, which are divided into three categories: Non-vulnerable area (64.575%), Medium Vulnerable area (23,386%), and Vulnerable area (12,039%) from the entire of the research area.

Nowadays, Mandeh Region has developed significantly as the center of marine ecotourism in West Sumatra Province. Many local and international tourists were visiting this site. Due to those conditions, many threats emerged, such as mass tourism evoking damages and pollutions. This study aimed to examine the feasibility of the Mandeh Region for tourism activity and identify the impacts of mass tourism. A direct survey has been conducted. We assessed water quality, accessibility, and social conflicts using a scoring method. A modified matrix categorizing some parameters as the underlying data for marine tourism sustainability was used. We also developed Smartline and CVI model to assess the vulnerability level along Mandeh coastal bay. Local zonation was recommended to reduce more environmental damages. We examined the feasibility of the Mandeh region as a place for ecotourism that reached 71.12 %, indicating this area is sufficiently feasible. The absence of local regulations before the Mandeh region was established as the center of marine ecotourism resulted in mass tourism phenomena that elevated marine litter accumulation. Moreover, the development of many resorts near the coast has recently played a role in triggering pollution and damage. Advanced regulation and management are necessary to diminish negative impacts on both the environment and society.
