“…However, there is some evidence showing signs of abrasion in the field, as indicated by the ridge slope and abandoned buildings. Mutaqin (2017) states that from 1995 to 2015, the shoreline at Kuwaru experienced a landward retreat of more than 50 m. In addition to massive abrasion that has damaged human settlements around the coast of Samas Beach, there is also a trend of accretion caused by sand blocking the estuary of Opak River and, thus, forming lagoons that prevent river water from flowing into the sea (Choirunnisa and Giyarsih, 2018). Figure 23 22 shows illegal beach sand mining at the estuary of Opak River.…”

Shoreline dynamics naturally occur in coastal areas, and over time, are also influenced by anthropogenic processes taking place both on-site and upstream. Bordering the Indian Ocean, the coastal area of Bantul Regency in the Special Region of Yogyakarta is faced with typical strong and high waves that induce changes in its shoreline dynamics and activities. Consequently, tourism, a leading economic sector in the area, often needs to adjust to such changes. Here, shorelines were extracted from the spatial data of time-series Sentinel 2A imagery (2015, 2016, 2017, 2018, 2019, and 2020) using water index transformation, MNDWI, while the land cover changes were analyzed using the Decision Tree classification. Based on the results, accretion appeared most significant from 2016 to 2017, creating an additional 22.32 ha. In contrast, shoreline change from 2019 until 2020 indicated the most severe abrasion that led to a loss of 34.89 ha. The highest rate of landward shoreline change was 41.58 m/year.

Indonesia now against catastrophic events due to the COVID-19 pandemic. Stringent preventive measures are one of the critical successes to control COVID-19 transmission. The level of public awareness influences adherence to preventive measures. This study investigated the level of awareness among junior high school toward COVID-19. A descriptive survey study using data collected via an online questionnaire was conducted between 30 th September and 2 nd October 2020. The survey instrument consisted 24 items, 10 items assessed knowledge, 8 items assessed attitude, and 6 items assessed practices. A total of 157 students took part in this study, of which 109 females and 48 males. The finding of this study shows that level of awareness among junior high schools toward COVID-19 is high. However, a significant number of students lack knowledge aspect, especially at the clinical symptom points of COVID-19, comorbidities that can aggravate COVID-19, the proper procedure for using masks, and determining the effectiveness of masks recommended by WHO. A comprehensive education program is essential to increase awareness and to reach sufficient knowledge related COVID-19.

Bandar Lampung City’s coastal area is highly susceptible to coastal hazards due to its location within the subduction zone of the Indo-Australian and Eurasian tectonic plates. Additionally, the presence of the Anak Krakatau volcano in the Sunda Strait further increases the vulnerability of the city’s coast to natural disasters. This study analyses the current social vulnerability in the coastal area of Bandar Lampung City. The aim is to provide a starting point for disaster management and policy planning in the city. To determine the level of social vulnerability in the coastal area of Bandar Lampung City, social vulnerability mapping is conducted by overlaying four indices: population, population density, sex ratio, and dependency ratio. The data indicates that there is significant variation in the level of social vulnerability among the coastal areas of Bandar Lampung City. Specifically, 8 out of 25 villages in the coastal area of Bandar Lampung City exhibit high levels of social vulnerability. The villages of Bumi Waras, Pesawahan, and Keteguhan have the highest levels of social vulnerability in the coastal area of Bandar Lampung City. As revealed by this study, the indicators of population size and dependency ratio have the most significant impact on the level of social vulnerability. These findings are expected to provide valuable input to stakeholders in their efforts to reduce social vulnerability in coastal areas.
