Abstract

Road infrastructure along the Kalaodi–Fabaharu corridor in Tidore Kepulauan has exhibited varying levels of surface deterioration, highlighting the need for an objective and standardized evaluation to determine appropriate treatment priorities. This study aims to assess the condition of flexible pavement using the Pavement Condition Index (PCI) method while also identifying key factors contributing to the observed damage. Field surveys were conducted on twenty selected road segments to record distress types, severity levels, and the extent of deterioration in accordance with ASTM D6433-11 guidelines. These data were then used to calculate PCI values, enabling the classification of pavement conditions across the study area. The findings show that PCI values range from 15 to 56, with an overall average of 27.48, indicating that the general pavement condition falls within the "Poor" category. The most prevalent distress types identified include alligator cracking, potholes, and raveling, which are primarily associated with inadequate drainage systems, environmental influences such as rainfall and surface runoff, and the lack of routine maintenance, rather than significant traffic loading. These contributing factors collectively accelerate pavement degradation and reduce structural performance over time. Based on the assessment results, the study concludes that the analyzed road corridor requires a phased and prioritized repair strategy. Immediate interventions should focus on patching critical failures and improving drainage performance to prevent further deterioration. Subsequent actions should include periodic rehabilitation for moderately damaged segments and full reconstruction for road sections exhibiting severe structural distress. This systematic approach is essential to restoring pavement functionality and ensuring long-term serviceability of the Kalaodi–Fabaharu road network.

Abstract

Access to safe drinking water remains a major challenge in many rural communities, including Kosa Village in Tidore Kepulauan, North Maluku, where borehole wells serve as the primary water source for domestic use. This study aims to assess the physical, chemical, and microbiological quality of borehole water in three hamlets of Kosa Village and to identify the potential factors contributing to water discoloration and odor frequently reported by residents. A descriptive analytical design was employed, and water samples were collected and analyzed at the UPT Puskesmas Soasio Laboratory from March to July 2025, following standardized APHA procedures. The results show that all sampling locations failed to meet national drinking water standards (PERMENKES No. 2/2023) for several physical parameters, including odor, color, turbidity, temperature, and Total Dissolved Solids (TDS). Chemical analysis indicated that residual chlorine levels in Hamlet 1 exceeded permissible limits (0.8 mg/L), while all other chemical and microbiological parameters in Hamlets 2 and 3 remained within the acceptable range. The deterioration in physical quality across all hamlets is likely influenced by geological characteristics, high iron and manganese content, domestic waste infiltration, and inadequate well maintenance. The findings highlight the need for regular monitoring, community-based water treatment strategies, and improved sanitation practices to ensure safe and sustainable access to drinking water in Kosa Village.
