Abstract

Lowita Beach was a tourist area in Suppa District, Pinrang Regency, with 11 tourist attractions. The annual increase in visitors to Lowita Beach can compromise tourist comfort and damage the area's natural habitat. This is the basis for researchers to analyse the Physical Carrying Capacity (PCC) of Lowita Beach. This study aimed to determine the characteristics of tourist activities, assess the physical carrying capacity of the area, and formulate the role of tourist villages in managing the Lowita Beach area. The research approach used was research and development, as initiated by Borg and Gall: the calculation of Physical Carrying Capacity (PCC), area parameters, and the number of tourists. The study population comprised 93 tourists who visited the Lowita Beach area. Data was collected through the completion of questionnaires, interviews, measurements, and field observations. A quantitative-descriptive approach was used for data analysis. The Physical Carrying Capacity (PCC) analysis reveals that Lowita Beach's ideal capacity is 1 visitor per day, yet it currently hosts an average of 35 visitors daily, significantly surpassing this threshold. This overcapacity indicates that the beach is experiencing environmental strain and underscores the need for management strategies to align visitor numbers with sustainable limits. In conclusion, despite the physical carrying capacity (PCC) of Lowita Beach being 17 visitors per day, the present daily visitor count suggests that the beach is currently facing overcrowding, albeit not to a significant extent. Hence, it is necessary to implement policy interventions from the tourist villages of Tasiwalie and Wiringtasi, which should include the establishment of standardized operating procedures and fostering collaboration among stakeholders, in order to ensure sustainable tourism management at Lowita Beach.

Abstract

This study examines seawater intrusion in the southern part of Kebumen District, focusing on the impact of various geological formations on groundwater salinity. Groundwater samples were systematically collected from 11 locations representing alluvial, volcanic, coastal sediment, and karst geological conditions. The samples were analyzed for major ions, including calcium (Ca²⁺), magnesium (Mg²⁺), chloride (Cl-), and bicarbonate (HCO₃-), as well as Total Dissolved Solids (TDS). Ion ratios such as Mg²⁺/Ca²⁺, Cl⁻/HCO₃⁻, and Mg²⁺/(Mg²⁺+Ca²⁺), along with the Fraction of Seawater (fsea), were calculated to assess the extent of seawater intrusion. The study employed the Gibbs diagram method to identify the primary processes controlling groundwater chemistry, revealing that water-rock interactions are dominant in most samples, particularly in those affected by seawater intrusion. The results indicate significant seawater intrusion in alluvial and karst regions, especially at sampling points TP 2, TP 4, and TP 10, while volcanic and coastal sediment areas show minimal intrusion. These findings underscore the critical influence of geological conditions on seawater intrusion and highlight the need for targeted groundwater management strategies. Further research focusing on long-term monitoring is recommended to better understand and mitigate the impacts of seawater intrusion in this region.
