Abstract

Groundwater quality degradation in small volcanic islands presents complex challenges for freshwater availability, particularly where communities heavily rely on groundwater resources. A study of groundwater dynamics in dug wells on Ternate Island, Indonesia, examined the relationship between water volume changes and water quality parameters while evaluating seawater intrusion potential through hydrostatic balance analysis. Researchers measured physical parameters (temperature, surface pressure) and chemical parameters (salinity, dissolved oxygen, electrical conductivity, total dissolved solids) in three sample wells and one coastal point. The analysis incorporated calculations of water volume changes, flushing rates, and regression analysis between water volume changes and water quality parameters to assess the dynamics of groundwater quality fluctuations. Water level changes showed a 27-minute lag after tidal shifts, with well 1 showing dominant volume changes during ebb tide (65%), while wells 2 and 3 were dominant during flood tide. Well 2 showed higher susceptibility to quality changes due to its lower flushing rate (13.7%) compared to well 1 (56.6%). Statistical analysis revealed that water volume increases did not significantly influence water quality changes (p > 0.05). These findings enhance our understanding of groundwater dynamics in volcanic islands and suggest that factors beyond water volume changes should be considered when managing groundwater resources in these settings. The research provides valuable insights for developing effective water resource management strategies in similar geological contexts worldwide.

Abstract

The Halmahera walking shark (Hemiscyllium halmahera) is a newly discovered endemic species found only in Halmahera's marine waters. Ternate Island's waters are known to provide habitat for the Halmahera walking shark species; the coastal water ecology is primarily made up of seagrass beds and reefs, which help to sustain the species' population. However, knowledge on ecological characteristics and distribution of walking sharks remains scarce. The study aimed to determine the habitat characteristics and distribution of this rare species on Ternate Island's coastal waters. This study was carried out from March to July 2024, with four stations located in the waters of Ternate Island. The data obtained included the number of walking shark sightings, water quality, seagrass bed characteristics, and coral reef conditions. The number of shark appearances varied significantly. The number of appearances was highest at Muhajirin Station and lowest at Kayu Merah Station. Seagrass beds at all four observation stations were categorized as damaged or poor, and coral reefs had begun to erode. Keywords: coral reef, habitat condition, Hemiscyllium halmahera, seagrass bed

Abstract

Graphical Abstract   Highlight Research DSAS based on geographic information systems has the ability to extract important information on the dynamics of shoreline changes, both accretion and abrasion. The dynamics of shoreline change in the short period of time 2018-2023 in the IWIP industrial area shows a very dynamic change process dominated by accretion. The conversion of beach into land was more prevalent than the process of shoreline retreat in the study area. The abrasion rate in this study area was categorized as moderate, while the accretion rate was categorized as very high due to construction activities.     Abstract The development of industrial estate infrastructure in coastal areas causes significant changes in coastal morphology. Despite extensive infrastructure development in coastal zones, limited empirical data exists on the shoreline dynamics of newly established industrial estates, particularly in Eastern Indonesia, thus highlighting the urgency of this study. This study investigates coastal morphology changes in the PT Indonesia Weda Bay Industrial Park (IWIP) industrial area over five years using Landsat 8 OLI level 2A satellite imagery and geospatial analysis. Shoreline extraction was performed using the Normalized Difference Water Index (NDWI) algorithm and analyzed with the Digital Shoreline Analysis System (DSAS) applying the Net Shoreline Movement (NSM), End Point Rate (EPR), and Linear Regression Rate (LRR) methods. The findings show that from 2018 to 2023, the shoreline in the PT IWIP area predominantly experienced accretion. The highest rate of shoreline accretion occurred in industrial zone, with a maximum of 147.58 m/year and an average of 36.56 m/year, while residential zones in the eastern and western regions experienced moderate abrasion, with a maximum of 12.32 m/year and an average of 4.11 m/year. Categorization followed standard DSAS criteria, where shoreline changes between 10–30 m/year were considered moderate, and changes above 30 m/year were classified as very high. Measurement accuracy was validated using high-resolution Google Earth imagery and Landsat metadata, ensuring positional accuracy within ±30 meters. These results highlight the rapid and spatially varied shoreline changes driven by industrial activities, emphasizing the importance of remote sensing in monitoring and managing coastal development impacts

Abstract

Pangkalan data paleo-tsunami Indonesia mencatat tanggal 28 Juni 1859 terjadi gempabumi kuat di Laut Maluku dengan skala intesitas (MMI) IX dan menyebabkan tsunami di Teluk Sidangoli dengan ketinggian 10 meter. Laut Maluku memiliki pengaruh yang signifikan terhadap potensi terjadinya bencana tsunami di sekitar wilayah Halmahera termasuk Jailolo Selatan. Melihat adanya potensi bencana tsunami yang besar di wilayah Jailolo Selatan, maka perlu dilakukan strategi perencanaan mitigasi bencana tsunami yakni dengan pemodelan bahaya tsunami. Pemodelan bahaya tsunami dilakukan untuk mengetahui nilai amplitudo maksimum (Run-up) gelombang tsunami dengan menggunakan perhitungan numerik dari sofware Cornell Multi-Grid Coupled Tsunami Model (COMCOT) versi 1.7, nilai jarak maksimum yang dapat ditembus oleh air pasang ke daratan pada pantai yang datar (inundasi), dan nilai sudut kemiringan lereng (slope) dari pengukuran fotogrametri udara Unmanned Aerial Vehicle (UAV). Hasil Pemetaaan bahaya tsunami menghasilkan nilai amplitudo maksimum (Run-up) setinggi 4 meter dan wilayah yang terdampak akibat gelombang tsunami berjarak (inundasi) sekitar 310 meter dari garis pantai. Nilai rata-rata sudut kemiringan lereng (slope) di pesisir Jailolo Selatan adalah 22,90 dan termasuk lereng curam. Dan slope tipe curam cenderung menyebabkan peningkatan tinggi gelombang saat tsunami mendekati pantai, sehingga gelombang dapat menjadi lebih tinggi.
