Abstract

Arosbaya is one of Madura's coastal areas on the north side of Madura Island. The Arosbaya River is a shipping channel for fishermen in the area to access the sea. To increase coastal potential, data on the depth of shipping lanes on the Arosbaya River is needed to ensure the safety of fishermen. Data on the depth of the shipping channel on the Arosbaya River was obtained from the results of a bathymetric survey. The aim of this research is to analyze the bathymetric conditions of the Arosbaya River waters and provide alternative solutions to the silting that occurs in fishing boat shipping lanes. A bathymetric survey was carried out on the Arosbaya River to the mouth of the Arosbaya River using a Garmin GPSMAP 585 sounding tool. Tidal data was obtained from secondary data and processed using the admiralty method to obtain the harmonic constant. It is known from the formzahl value obtained that f > 3 which means high and low tides. single daily type (diurnal tide). The water level height values ​​obtained were the highest high water level (HHWL) = 1.14 M, mean sea level (MSL) = 0 M, lowest low water level (LLWL) = -1.14 M which was used as a correction in the bathymetric sounding results for making shipping lanes. Soundings were carried out in the survey area with the deepest depth found, namely 2.6 meters which has been corrected for the lowest astronomical tide (LAT). Measurements on 2 types of fishing boat draft, namely curved and boat types, showed that the average draft height was 90-100 cm and 50 cm when the boat was empty without cargo in the water. Both types of fishing boats are included in boats measuring < 5 GT. The depth that the boat can traverse when empty is 50 cm, which makes the channel area smaller because it conforms to an appropriate and safe contour depth (≥ 50 cm). Based on the corrected bathymetry map, the area east of the river has a suitable depth and is safe to pass. The depth of the water at the lowest ebb has the potential to disrupt ship traffic because the area that is safe to pass through is reduced so that it is possible that traffic at the mouth of the river cannot move simultaneously to get in and out of fishing boats.es

Abstract

PLTGU (Gas and Steam Power Plant) is a combination of gas power plant and steam power plant. PLTGU requires a cooling water systems during its operational life. The required amount of cooling water will increased along to increased power capacity of power plant. This project contains jetty extension study due to the addition of power capacity on thermal water dispersion at PLTGU Grati, Pasuruan. The results show using Delft3D hydrodynamic model, The alternative model showing quite good performance decreased temperature of cooling water on average 0.7975 oC at inlet canal. But it only need 2.5 oC increase of seawater temperature to decrease 0.33% efficiency, so it might change nothing to thermal power plant efficiency compared to the model result. Considering to the increasing risk of sedimentation rate, this alternative might be poor layout but further research needed. Still the best choice is on existing jetty design.

Abstract

Indonesia’s marine environment is highly sensitive to global climate variability, particularly El Niño–Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). This study analyzes the spatial and temporal variability of sea surface temperature (SST) and chlorophyll-a concentration and their relationship with ENSO and IOD in Sumenep waters, Madura Island. SST and chlorophyll-a data were derived from Aqua MODIS satellite observations for the period 2014–2024, while ENSO and IOD were represented by the Oceanic Niño Index (ONI) and Dipole Mode Index (DMI). Data were analyzed using temporal trend analysis, spatial mapping, and Pearson correlation. The results show that SST fluctuated between 28.01 and 30.75 °C, with higher temperatures during El Niño phases and lower temperatures during La Niña phases. Chlorophyll-a exhibited relatively stable minimum values (0.178–0.217 mg/m³), while maximum values varied between 0.499 and 0.782 mg/m³, peaking in 2020. Pearson correlation analysis indicates a strong relationship between ENSO and SST (r = 0.791) and a very strong relationship with chlorophyll-a (r = 0.898). In contrast, IOD shows very weak correlations with SST (r = 0.074) and chlorophyll-a (r = 0.211). These findings confirm that ENSO is the dominant driver of SST and chlorophyll-a variability in Sumenep waters, with important implications for regional marine productivity.

Abstract

Prancak Village is a coastal village located in Sepulu Subdistrict, Bangkalan Regency, which has an important ecosystem in the form of coral reefs and seagrass beds. This study aims to map the distribution of bottom sediments and determine the influence of hydrodynamic conditions on sediment distribution. Data collection was conducted at 20 stations using a core sampler, and sediment samples were analyzed for granulometry in the laboratory. Supporting parameters such as currents, waves, tides, and bathymetry were also recorded. The results of this study show that bottom sediments in the coastal area of Prancak Village are dominated by sand with a sand content of 94.914-99.598% and silt and clay content ranging from 0.323-5.086%. The results of sediment classification showed that fine sand dominated at some points, while coarse mud dominated at other locations. The dominance of sandy sediments in the coastal area of Prancak Village creates substrate conditions that support seagrass growth and the sustainability of the coral reef ecosystem. This study provides information on the distribution of bottom sediments as a basis for coastal management and development planning, as well as erosion and sedimentation mitigation in the coastal area of Prancak Village, Bangkalan Regency.

Abstract

Coastal areas are highly dynamic environments facing increasing threats from both natural processes and human activities, such as coastal erosion, sea level rise, and land use changes. Prancak Village is one such coastal area vulnerable to geomorphological changes. This study aims to assess coastal vulnerability through geomorphological analysis using the Coastal Vulnerability Index (CVI) method. Data were collected from primary and secondary sources, including satellite imagery, field surveys, digital elevation models (DEMs), and data from relevant agencies. The analyzed parameters comprised coastal morphology, beach slope, shoreline change, wave height, and tidal range. The CVI calculation yielded a value of 6.93, which falls within the 5.8–10.06 range classified as “low vulnerability” (20–40% vulnerability level), indicating that the study site has relatively low susceptibility to the physical factors assessed Although the overall index is low, local physical dynamics still pose risks in certain areas, confirming that geomorphology and coastal ecosystem conditions are more decisive in determining vulnerability than oceanographic parameters such as wave height.

Abstract

This study aims to analyze the tidal characteristics in the southern coastal area of ​​Madura using the least squares-based harmonic analysis method with Python programming. This method is used to obtain tidal harmonic constants and determine the tidal type in the study area. The analysis results show that the M₂ component is the dominant component with an amplitude of 0.498 m, followed by the K₁, O₁, and S₂. The Formzahl value of 1.056 indicates that the tidal type in the southern coastal area of ​​Madura is a mixed tide tending to be semidiurnal. Model validation using the Root Mean Square Error (RMSE) produced a value of 0.201 m, indicating that the modeling results have a fairly good level of accuracy. The results of this study are expected to be a reference in the planning and management of coastal areas in Madura waters.
