| Abstract (English): | This study aims to find possible active faults by analysing the morphotectonic features of the Cikandang Watershed in West Java, Indonesia. Morphometric indices including drainage density (Dd), lineament density (Ld), and bifurcation ratio (Rb) were computed using digital elevation models, topographic maps, and geological maps using Geographic Information System (GIS) software. As demonstrated by the different drainage patterns and lineament alignments that show tectonic activity, the analysis shows that tectonic forces substantially impact the watershed's shape. Higher Rb levels in sub-drainages suggest tectonic activity, while elevated Dd and Ld values indicate areas that are more susceptible to tectonic movements. These indices show possible active fault zones and strongly correlate with those shown on regional geological maps, especially in the watershed's centre and northern regions. In line with earlier studies that connected geomorphic indices to tectonic activity, the findings support the importance of these indicators in identifying active faults. This study highlights the importance of comprehensive morphotectonic assessments in determining earthquake hazards, providing vital information for disaster risk management and spatial planning in tectonically active areas. Through the alignment of geomorphic indices with geological features, the study pinpoint's fault zones that need continuous observation, promoting safer community development and more resilient infrastructure in West Java's earthquake-prone areas.

| Abstract (Croatian): | Cilj je istraživanja pronaći moguće aktivne rasjede analizom morfotektonskih značajki slijeva Cikandang u Zapadnoj Javi, Indonezija. Morfometrijski indeksi, uključujući gustoću drenažne mreže (Dd), gustoću lineamenata (Ld) i omjer bifurkacije (Rb), izračunani su pomoću digitalnih modela reljefa, topografskih i geoloških karata korištenjem Geografskoga informacijskog sustava (GIS). Kao što je prikazano različitim oblicima drenažne mreže i orijentacijom lineamenata koji upućuju na tektonsku aktivnost, analiza pokazuje da tektonske sile znatno utječu na oblik slijeva. Više Rb vrijednosti u pojedinim dijelovima drenažne mreže upućuju na tektonsku aktivnost, dok povišene vrijednosti Dd i Ld upućuju na područja koja su podložnija tektonskim pokretima. Ti indeksi upućuju na moguće aktivne rasjedne zone i jako koreliraju s onima prikazanima na regionalnim geološkim kartama, posebno u središnjemu dijelu slijeva i sjevernim regijama. U skladu s ranijim studijama koje su povezivale geomorfološke indekse s tektonskom aktivnošću rezultati podupiru važnost tih pokazatelja u identificiranju aktivnih rasjeda. Ovo istraživanje naglašava važnost provedbe sveobuhvatnih morfotektonskih analiza u određivanju opasnosti od potresa pružajući ključne informacije za upravljanje rizikom od katastrofa i prostorno planiranje u tektonski aktivnim područjima. Usklađujući geomorfološke indekse s geološkim značajkama, ovo istraživanje uputilo je na rasjedne zone koje je potrebno kontinuirano promatrati promičući sigurniji razvoj zajednice i nužnost otpornije infrastrukture u potresnim područjima Zapadne Jave.
