“…Benoa Waters tidal data obtained from UHSLC produces harmonic constant values using the least square method, which is the value of amplitude and phase latency, including S0, M2, S2, N2, K2, K1, O1, P1, M4, and MS4, the results of which will then be used as parameters to find the Formzahl score [8]. So that the type and characteristics of tides in Benoa Waters can be known in the following Table From the results of these observations, it can also be found that the Formzahl score is 0.414, this score means that Benoa waters has a mixed-semidiurnal type [9].…”

As one of the oceanographic parameters, the tidal range can be used as a source of blue energy in producing renewable energy such as electricity in Indonesian territory, especially in small islands. Utilization of tidal ranges in producing electrical energy will be more environmentally friendly when compared to Steam-Electric Power Station, which require coal resources as a power source. This research aims to determine the potential for renewable energy from tides in Benoa waters, Bali. The data used in this study is sea level data from tide gauges sourced from the University of Hawaii Sea Level Center (UHSLC). Analysis of tidal types and components in this study was carried out using the least squares method using the R program language. The results showed that the tidal type of Benoa waters is a mixed-semidiurnal tide. In 2020 and 2022, the highest tidal ranges are 2.46m (in December) and 2.3m (in March, November, and December), respectively. The simulation results for a 1000 m2 pond show that the energy potential in 2020 is 24.0 kWh and in 2022 it is 27.7 kWh. The tidal value’s magnitude influences the tidal energy potential; the more significant the tidal value, the greater the energy produced.

“…This can be caused by many factors, either natural or human-induced. Various natural variables, such as tides, waves, coastal currents, water level, changes in wind direction, storms, and hurricanes-cyclones events, can impact coastal dynamics in the form of erosion and sedimentation (Clifton, 2003;Marfai et al, 2022;Morner, 2017;Mutaqin, 2017;Mutaqin & Ningsih, 2023). The presence of sea walls and other buildings can also affect it (Bird, 2019;Marfai et al, 2022).…”

Indonesia is considered one of the biggest archipelagic countries in the world. According to some literature, Indonesia has more than 17,000 islands, most of which are classified as small islands. Some of these islands have become important areas for tourism, for instance, small islands in Karimunjawa. However, some of these islands experienced shoreline changes caused by erosion and accretion. Hence, this research aims to map the spatial distribution of shoreline change using the Digital Shoreline Analysis System (DSAS) add-in on ArcGIS. The primary dataset utilized as input consists of Sentinel 2A imagery captured over 2017 and 2022. The results showed that around 89 segments, or 51.47% of the total shoreline segments, tend to experience accretion, while the remaining 79 segments, or 45.93%, experience erosion. This finding suggests that most shoreline segments tend to accrete or seaward movement in the research area. The results of this study exhibit notable disparities when compared to the occurrences observed in Pandeglang (Banten), Kuwaru (Yogyakarta), Buleleng (Bali), and East Java Province, where coastal erosion prevails over accretion. The managers of the islands try to reduce the threat of erosion by constructing dykes and breakwaters. However, these buildings are ineffective due to the relatively simple structures and building materials. Therefore, further studies are needed to determine the type and specification of mitigation buildings that are suitable for implementation in that location.
