Abstract

Accurate rainfall data are essential for reliable hydrological analysis, yet different measurement methods can yield varying estimates, and the true areal precipitation cannot be directly observed. This study evaluates three rainfall datasets—BMKG observations, Global Precipitation Measurement (GPM), and Automatic Rainfall Recorder (ARR)—using the Extended Triple Collocation (ETC) method in the Cimanceuri Watershed, Indonesia. Daily rainfall data from two representative locations were temporally and spatially collocated for comparative analysis. The results demonstrate location-dependent differences in dataset performance. At Budiarto–Curug, GPM produced the lowest estimated error (RMSE = 7.62 mm), whereas ARR achieved the highest correlation with the unknown rainfall signal (r² = 0.83). At Tangerang–Kresek, ARR showed the best overall performance, with the lowest RMSE (7.26 mm) and highest r² (0.65), while BMKG exhibited the highest error (RMSE = 15.94 mm). Ground-based datasets captured greater rainfall variability, whereas GPM provided smoother estimates. These findings indicate that rainfall dataset performance is influenced by location, spatial variability, and measurement characteristics. ETC offers an objective framework for evaluating rainfall datasets in the absence of a known reference and supports data selection for hydrological modeling and water resources management.

Abstract

The development of urban green open spaces requires reliable drainage infrastructure to ensure environmental sustainability and functional performance. The construction of a fountain pond park in the Digulis Monument area, Pontianak City, Indonesia, required an underground drainage system to convey excess water to the municipal drainage network without compromising the stability of Ahmad Yani Street, a national roadway with heavy traffic. Precast box culverts are widely used in urban drainage systems due to their structural efficiency and rapid installation. However, few studies have examined the long-term field performance of geotextile-protected culvert joints, particularly under soft-soil conditions. This study evaluates the technical performance of a precast reinforced concrete box culvert (1.5 m × 1.5 m) with 25 MPa concrete strength and D16–150 mm reinforcement used as the drainage conduit for the fountain pond system. The analysis includes a hydrological assessment, reinforced concrete structural evaluation, and a review of construction methods. Field observations conducted more than a decade after installation indicate that the system remains hydraulically functional and structurally stable. The results provide long-term empirical field evidence that geotextile protection at culvert joints can improve the stability of precast drainage systems constructed on soft soil.

Abstract

Bekasi Regency, West Java, is located in a seismically active region of Indonesia, making seismic performance evaluation important for assessing the safety and reliability of reinforced concrete buildings. This study evaluates the seismic performance of a special dual reinforced concrete structural system using the Nonlinear Static Pushover (NSP) procedure in accordance with ASCE/SEI 41-17. A three-dimensional structural model was developed in ETABS v22, with nonlinear behavior represented using plastic hinges for beams and columns and fiber-based hinges for structural walls. The building response was evaluated under the Design Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE) hazard levels using performance-point response, interstory drift ratios, and plastic hinge development. Under the DBE level, the maximum interstory drift ratios were 0.976% and 0.785% in the X- and Y-directions, respectively, satisfying the 1.0% acceptance limit for the Immediate Occupancy (IO) performance level. Under the MCE level, the maximum drift ratios were 1.776% and 1.265% in the X- and Y-directions, respectively, remaining below the 2.0% acceptance limit for the Life Safety (LS) performance level. Plastic hinge evaluation showed that no structural elements progressed to the LS or Collapse Prevention (CP) levels. The results indicate that the investigated dual structural system provides adequate seismic performance and satisfies the specified acceptance criteria under both hazard levels. Keywords: Seismic performance; Dual reinforced concrete system; Nonlinear static pushover; ASCE/SEI 41-17; Bekasi Regency.
