“…The utilization of the coastal regions is often not based on an understanding of coastal behavior can cause various coastal problems to appear, such as accretion or abrasion. Abrasion and accretion processes that previously occurred naturally can occur more quickly if the behavior of development interests is not based on knowledge of the dynamics of coastal waters and can result in faster shoreline changes (Syukhriani et al, 2017). Monitoring shoreline changes is essential to determine changes along the coast and their mitigation efforts.…”

Masakambing Island is one of the small islands in Sumenep Regency which has its own uniqueness and beauty. Small islands easily experience changes, one of which is changes in coastlines. The aim of this research is to determine the changes that occur along the coast and mitigation efforts by utilizing hydro-oceanographic parameters. Measurements of coastline changes were obtained from digitization results using the Normalized Different Water Index (NDWI) method with structural and non-structural mitigation efforts based on the parameter data taken. Wind parameters are dominated from the southeast and east with speeds ranging from 0.09 m/s - 22.75 m/s. The wave parameter values obtained were between 0.25 m – 0.83, while the current parameters ranged between 0.006 m/s – 0.642 m/s with the Formhazal number values showing 1.5 – 1.8. The wind was blowing cool and strong, as was the wave height in the slight category. The current flows southwest from the north of the island to the east. Single daily mixed Tide Type. The reduction in the area of Masakambing Island ranges from 0.063 km2 – 1.933 km2. Mitigation efforts that can be considered structurally include creating breakwaters and revetments, strengthening coastal buildings and planting vegetation. Non-structural mitigation that can be carried out includes creating standardization policies for disaster-resistant buildings, exploration and economic activity policies, public awareness as well as counseling and outreach regarding disaster mitigation.

“…Indonesia has the second longest coastline in the world (Arief et al, 2011). Bengkulu City Beach is a beach that is directly opposite the Indian Ocean when viewed from the geographical condition which is a sandy beach and includes a sloping beach (Syukhriani et al, 2017). Coastal land is a marginal land that has low productivity (Achmad, 2016).…”

This study aims to determine the effect of humic acid on nutrient availability and upland rice production in coastal land. The research was carried out in June - November 2020 in the Beringin Raya Village, Muara Bangkahulu District, Bengkulu City. This study used a completely randomized block design with 2 factors. The first factor was the local Bengkulu upland rice variety, namely the Red upland rice variety and the White upland rice variety, while the second factor was the type of fertilizer, namely control (basic fertilizer only), humic acid, and fertilizer recommended for upland rice from BPTP (200 kg Urea ha-1, 100 kg SP36 ha-1, 100 kg KCl ha-1). The results showed that the administration of humic acid in both the White and Red varieties resulted in the best KCl pH. And if you look at the yield per plot, the upland rice of the Red variety is better when given humic acid, which has an increase of 7.4% g/plot, while the White variety has better results when given the recommended inorganic fertilizer, which is an increase of 12% g/plot. The Red variety had a higher soil pH, but had a number of pithy grains per panicle, and a lower grain content percentage than the White variety. The application of humic acid resulted in better KCl, CEC, and N-total pH, but had plant height, number of pithy grains per panicle, and yields per plot that were almost the same as recommended inorganic fertilizers.

Visual interpretation of remote sensing data is very popular and widely used to detect, extract and monitor changes in shoreline. Commonly used satellite images include: IRS, Landsat TM and ETM +, IKONOS, Quickbird, Worldview2 and Geoeye-1. To find out the changes in coastline and coastal erosion rates in Klungkung regency was carried out by comparing two satellite images, namely SPOT 5 satellite image data in 2009 having a spatial resolution of 10 m and SPOT 6/7 in 2015 which resolution up to 1.5 m with digital on screen extraction method. This research contributes to local government and central government as basic data in making decisions for handling coastal areas. The average shoreline change that occurs in Klungkung regency is 22.15 m, while the average coastal erosion rate in Klungkung regency is 3.16 m/year.
