“…Although a small number of studies have investigated the effects of monochromatic ALAN on cyanobacteria and microalgae, these focused on benthos and periphyton [2,[26][27][28][29][30], while no study so far has investigated the effects of polychromatic LEDs on marine phytoplankton. Due to the continuous expansion of coastal urbanization [31,32], ALAN is a source of pollution that is increasingly relevant for coastal ecosystems [4,21]. Coastal ecosystems globally are also increasingly affected by eutrophication and harmful algal blooms (HABs) due to nutrient-rich inflows from either agricultural or urban sources [33,34].…”

Wavelength-dependent effects of artificial light at night on phytoplankton growth and community structure

Artificial light at night (ALAN) is a disruptive form of pollution, impacting physiological and behavioural processes that may scale up to population and community levels. Evidence from terrestrial habitats show that the severity and type of impact depend on the wavelength and intensity of ALAN; however, research on marine organisms is still limited. Here, we experimentally investigated the effect of different ALAN colours on marine primary producers. We tested the effect of green (525 nm), red (624 nm) and broad-spectrum white LED ALAN, compared to a dark control, on the green microalgae Tetraselmis suesica and a diatom assemblage. We show that green ALAN boosted chlorophyll production and abundance in T. suesica . All ALAN wavelengths affected assemblage biomass and diversity, with red and green ALAN having the strongest effects, leading to higher overall abundance and selective dominance of specific diatom species, some known to cause harmful algal blooms. Our findings show that green and red ALAN should be used with caution as alternative LED colours in coastal areas, where there might be a need to strike a balance between the effects of green and red light on marine primary producers with the benefit they appear to bring to other organisms.

“…Changes in land use in coastal areas will affect the intensity of sedimentary transport, inducing stabilization of the landform, vegetation characteristics (Marrero-Rodríguez et al, 2020). The distribution of human activity in coastal areas is influenced by geomorphological factors (Yi et al, 2020). Preliminary observations of the coast must be carried out with the aim of maintaining environmental quality (Scherelis et al, 2020).…”

This study aims to place the tidal energy installation effectively in Indonesia based on geomorphological factors. The survey method was used to analyze the characteristics of beaches in Indonesia. Mathematical physics model was implemented to find the new formulas based on geomorphological factors. Tides are the result of gravitational attraction and the centrifugal effect, which is the drive In the earth-moon system, tidal generating forces are the resultant forces that cause tides, namely: the earth-moon system (FS) centrifugal force and the moon's gravitational force (FB). FS works in the center of the mass of the earth-moon system whose mass point is located on the 3/4 radius of the earth. The style of tidal generator caused by the moon can be calculated by combining Newton's universal gravitational law .The results of this study consist of F = m ac, where the style of the tidal generator caused by the moon can be calculated by combining newton's universal gravitational law in equation and newton's second law of motion in Equation. The another results is tan = , where the formula takes into account constants (K) based on slopes. The last result is the constants (K) for each land form starting on 0,00 untill 1,00. The north coast of Java is more suitable for tidal energy installations because the land form is dominated by alluvium plains of the quaternary age with a lower risk than the southern region of Java. The effectiveness of tidal energy installation depends on the characteristics of the land form. In alluvial plains, the quaternary age of the alluvial plains is more suitable than the hill form volcanic quaternary, tertiary volcanic, and tertiary holokarst.

“…As a place of transition between land and sea, the coast holds a wide variety of resources [1]- [4]. In its development, the coast began to experience a decline in quality due to excessive utilization [5]- [8]. At the same time, the coast is also prone to various natural disasters such as high winds, tsunamis, erosion, tidal flooding, and climate change [9], [10].…”

Small islands possess the main character, namely limited land resources; thus, their development must pay attention to the land's capability to support life. Sulabesi is one of the small islands located in the North Maluku Islands with a very low to very high level of land capability. As a small island and center of activity, it faces several problems, including population growth, land availability, and vulnerability to natural disasters. The study aimed to assess the suitability of land capability with land cover and disaster risk and provide direction for the development. Additionally, it employed an overlap analysis method using the ArcGIS 10.5 tool with spatial data, namely land capability and disaster risk, and land cover changes from Landsat 7 & 8 satellite imagery throughout 2000, 2010, and 2020. The research finding denoted that Sulabesi Island continues to experience changes in land cover, particularly the increase in built-up land for 20 years. These changes were then spread over the land capability of class A and class B development capability characteristics of 280.46 ha. Furthermore, the suitability between land capability and disaster risk areas was also observable in classes A, B, and C, with the risk of tsunamis, earthquakes, and landslides. Thus, efforts to manage sustainable land use, mainly built-up lands, must be directed at the capability of land with a very high -medium development classification and free from disaster risk. It can be a reference for future research in developing small islands that are more resilient.
