Abstract

 Kupang City and Kupang Regency have semiarid climatological conditions where annual rainfall ranges from an average of 1,250 mm/year. Kupang City and Kupang Regency experience long days without rain, which potentially causes meteorological drought. The study aims to determine the value and distribution of the drought index in Kupang City and Kupang Regency. This study uses the Standardized Precipitation Index (SPI) method using rainfall data for 21 years (1998-2018) from 12 rainfall stations, while the mapping uses ArcGIS Software. The results obtained from this study are the extreme level of drought in Kupang Regency and Kupang City occurred in 2015-2016. A 1-month SPI Kupang City experienced the highest drought in January 2004 at -3.48, while Kupang Regency occurred in November 2015 at -3.06.  The 3-month SPI Kupang City experienced the highest drought in January 2016 at -3.85, while Kupang Regency occurred in December 2012 at -4.13. The 6-month SPI of  Kupang City experienced the highest drought in January 2016 at -4.04, while Kupang Regency occurred in November 2015 at -4.82.  The 12-month SPI Kupang City experienced the highest drought in March 2016 at -3.76, while Kupang Regency occurred in April 2016 at -3.36. The 6-month SPI tends to fluctuate more in value than the 1-month SPI, 3-month SPI, and 12-month SPI. The drought years that occurred in 2015 – 2016 triggered forest and land fires in Kupang City. Besides that,  the Meteorological drought must be anticipated by setting appropriate cropping patterns to avoid food insecurity. Keywords: Drought, semiarid, land fires, mapping

Abstract

The semi-arid region of East Nusa Tenggara (NTT) faces increasing environmental pressures, including prolonged droughts, rising surface temperatures, and rapid runoff during short, intense rainfall events. These conditions necessitate nature-based solutions to restore hydrological balance and strengthen climate resilience. This study aims to identify the effectiveness of Green Infrastructure (GI) and Blue Infrastructure (BI) in addressing water scarcity and urban heat challenges, and to formulate an integrated GI–BI model that is adaptive to the socio-ecological conditions of NTT. A Systematic Literature Review (SLR) was conducted following PRISMA guidelines by examining nine recent international publications on GI–BI performance in semi-arid regions. Synthesis of the nine studies indicates that combinations of GI elements (bio-retention, green roofs, vegetated spaces, street trees) and BI components (retention ponds, natural channels, micro-reservoirs) consistently contribute to restoring 82–90% of pre-development water balance, reducing runoff by 35–45%, and lowering air temperatures by 3–5°C, depending on spatial configuration and local climatic variability. Key barriers to implementation include limited financing, weak cross-sectoral coordination, and insufficient long-term performance data. These findings underscore that GI–BI functions not only as technical interventions but also as critical policy instruments for adaptive spatial planning, green financing frameworks, and remote-sensing–based environmental monitoring in NTT. The study highlights the urgency of developing an integrated long-term implementation framework to ensure the sustainability of GI–BI adoption in enhancing regional climate resilience

Abstract

Hot and semi-arid climates present critical challenges to concrete performance due to rapid water evaporation and the interruption of cement hydration. Curing, as the post-casting phase, functions to maintain adequate temperature and moisture to ensure complete hydration. This paper presents a mechanistic synthesis of six major international studies analyzing the effect of curing on microstructural development and durability of concrete under hot and semi-arid environments. Findings show that curing effectiveness strongly depends on maintaining thermal and moisture stability within the first 3–7 days. Methods such as film curing, moist curing, and thermal–moisture insulation curing (TMIC) effectively reduce water loss by up to 40% and increase compressive strength by 20–35% compared to uncured specimens. Mechanistically, effective curing enhances the formation of dense Calcium Silicate Hydrate (C–S–H) gels, reduces porosity, and improves resistance to chloride ion penetration. The synthesis concludes that adaptive climate-based curing strategies are crucial for ensuring long-term durability of concrete infrastructures, especially in semi-arid regions like East Nusa Tenggara, Indonesia.
