This study examines the carbon capture potential of mangrove ecosystems, focusing on the Randuboto mangrove conservation area. The total biomass in the area amounts to 172.031 tons/ha, with a carbon storage capacity of 80.855 tons/ha and CO2 capture of 296.738 tons/ha. The sapling stratum, characterized by greater mangrove density, produces higher biomass and accommodates more carbon reserves compared to the mature tree stratum. Avicennia marina is identified as the most significant contributor to biomass, carbon storage, and CO2 absorption. Mangroves, through their dense root systems and photosynthetic processes, trap and store carbon both in their biomass and in waterlogged sediments, where decomposition is slowed. Additionally, tidal exchanges enhance carbon capture by promoting the deposition of organic material, further increasing carbon storage in coastal areas. These ecosystems play a crucial role in mitigating climate change by sequestering large amounts of carbon, protecting coastal habitats, and supporting biodiversity, emphasizing the need for their conservation in climate action strategies.

Global warming comes from many human activities, such as the burning of fossil fuels and the use of energy can produce Greenhouse Gases. The energy sector itself is the largest contributor of greenhouse gases in the world. This study aims to determine the greenhouse gas emissions produced in the energy sector on Gili Iyang Island. To be able to determine the greenhouse gas emissions produced in the energy sector on Gili Iyang Island, the IPCC 2006 calculation method was used. In this method, primary data is needed in the form of data on energy and fuel consumption activities of residents and secondary data in the form of the number of families on Gili Iyang Island. In the stationary source itself, CO2 gas emissions are produced at 1,438,259.9 Kg/Year, CH4 gas at 324.164 Kg/Year, and N2O gas at 12.486 Kg/Year. Meanwhile, moving sources produce CO2 gas emissions of 510,339.1052 Kg/Year, CH4 gas of 191.363 Kg/Year, and N2O gas of 20.969 Kg/Year. As for mitigation actions that can be taken based on its topography and climate, Gili Iyang Island has the potential to use solar panels and biogas as alternative energy and fuel sources to meet daily needs.

Household drinking water needs are often estimated solely based on population size, without adequately considering local characteristics. This study aims to assess household drinking water requirements in a semi-urban island setting, using Gili Iyang Island in Sumenep Regency as a case study. The analysis refers to the Indonesian National Standard (SNI) 6728-1:2015, which defines the daily water requirement for semi-urban areas as 60–90 liters per person. Data were collected through a questionnaire survey involving 100 respondents and analyzed quantitatively using Microsoft Excel and the Kruskal–Wallis statistical test via SPSS. The results indicate that the average household water consumption in Gili Iyang is 132.20 liters per person per day, significantly exceeding the SNI range. Economic status was found to have a statistically significant influence on water consumption levels (p = 0.001), while educational level did not show a significant effect (p = 0.137). These findings suggest that determining household drinking water needs should not rely solely on regional classification and population figures but must also account for local socio-economic factors. Therefore, this study serves as a basis for water supply system development in Gili Iyang Island and offers valuable insights for evaluating and planning future water supply systems, particularly for island regions with similar conditions.

Sandblasting waste from the blasting process of ship construction has a high potential to pollute the air and a negative impact to the environment or human health. Nowadays the sandblasting waste from the blasting process of the ship construction industry has not been well managed, Therefore, it is necessary to characterize sandblasting waste and to select and apply an appropriate sandblasting waste control device. Tests was carried out by taking particulate samples in the site with High Volume Air Sampler (HVAS) equipment followed by the Gravimetric method, Scanning Electron Microscopy (SEM) and Atomic Absorbtion Spectrophotometry (AAS). The gravimetric method was used to test the concentration of sandblasting waste with an average yield of 6,654.545 mg/m3. The particulate size obtained from SEM testing was 1.751 to 63.03 µm, testing with the AAS method to get the value of heavy metal content of Fe and Al on average of 1.6375 mg/m3 and 2.2925 mg/m3. Control technology that can use for sandblasting waste are Gravity Settling Chamber or Cyclone for preremoval and Bag Filter or Scrubber or Electrostatic Precipitator as an advance removal.Keywords: ships construction, Sandblasting and Particulate control technology
