Abstract

Mangrove ecosystems play a crucial role in climate change mitigation, particularly through blue carbon sequestration and the protection of coastal areas. This study aims to identify the initial characteristics of the coastal waters on the western side of Lancang Besar Island, Thousand Islands, based on parameters including depth, pH, temperature, and total dissolved solids (TDS). The findings are compared against relevant seawater quality standards, specifically those stipulated in Government Regulation of the Republic of Indonesia Number 22 of 2021 concerning the Implementation of Environmental Protection and Management. Measurements were conducted on October 8, 2026, along a single transect comprising 21 observation points, spaced at 50 cm intervals, extending from 0 to 1,000 cm from the shoreline. Data were analyzed using descriptive statistics and by examining parameter profiles in relation to the distance from the shore. The results indicate that water depth ranged from 4 to 60 cm (mean: 28.19 cm); pH ranged from 8.1 to 9.0 (mean: 8.50); ​​and temperature ranged from 32 to 33 °C (mean: 32.33 °C). Following adjustment based on the instrument's multiplier factor, TDS values ​​ranged from 172 to 8,790 mg/L. A preliminary comparison with Appendix VIII of Government Regulation Number 22 of 2021 reveals that pH values ​​do not consistently fall within the 7.0–8.5 range established for marine biota. Similarly, temperatures within the mangrove ecosystem do not entirely align with the 28–32 °C reference range, although a deviation of up to 2 °C is permitted. TDS values ​​cannot yet be categorized as compliant or non-compliant based on the provided standards, while water depth serves as a physical characteristic of the aquatic environment. The data obtained can serve as a basis for planning the assessment of vegetation structure, mangrove biomass, and sediment organic carbon content to support the estimation of blue carbon stocks.

Abstract

Standard hooks are commonly used to anchor beam reinforcement in exterior reinforced concrete (RC) beam–column joints, where the hooked-bar development length often governs the column depth. SNI 2847:2019 adopts ACI 318-14 and has not incorporated the revisions in ACI 318-19 and ACI 318-25. This study aims to compare the standard and seismic hooked-bar development lengths of SNI 2847:2019, ACI 318-19, and ACI 318-25 and to identify the conditions under which they differ materially. The comparison covers the governing equations, modification factors, and applicability limits. It also includes a controlled parametric analysis (D16–D57 bars,  = 28 MPa,  = 420 and 550 MPa) and design examples of an exterior joint with a 600 × 600 mm column. ACI 318-19 gives considerably longer hooked-bar development length than SNI 2847:2019, particularly for large bars and joints without confinement. ACI 318-25 gives identical the hooked-bar development length for bars up to D29 and only moderately longer values for larger bars. The seismic provision is identical in all editions and is not always shorter than the standard provision. The code revisions therefore mainly affect intermediate and ordinary moment frames and D32 and larger bars.
