Abstract

Abstrak. Kota Makassar merupakan salah satu wilayah yang cukup rentan akan kejadian atau bencana hidrometeorologis, khususnya banjir yang umumnya disebabkan oleh intensitas curah hujan dan penggunaan lahan yang setiap tahun mengalami perubahan. Tujuan dari penelitian ini adalah untuk mengetahui intensitas curah hujan agar dapat melakukan antisipasi mengurangi resiko terjadinya banjir di Kota Makassar. Adapun metode yang digunakan yaitu studi literatur mengenai konsep curah hujan wilayah, analisis data dan pemetaan untuk mengetahui upaya yang sesuai untuk mengurangi resiko banjir. Hasil dari penelitian ini menyatakan bahwa curah hujan tertinggi berada pada kawasan kecamatan dengan persentase yang berbeda dan diperoleh hasil bahwa hampir seluruh wilayah Kota Makassar Memiliki curah hujan yang cukup tinggi, terlebih wilayah tersebut seluruhnya merupakan daerah dataran rendah yang berpotensi tergenang saat curah hujan yang turun besar. Tahun 2018 Kota Makassar telah mengalami perubahan penggunaan lahan menjadi kawasan terbangun sekitar 75% dari luas wilayah Kota Makassar. Untuk itu upaya yang tepat untuk daerah dengan intensitas curah hujan yang tinggi dan telah mengalami perubahan lahan yaitu dengan melakukan penyediaan fasilitas pengendalian banjir yang memadai dan memberikan edukasi kepada masyarakat dalam hal pemanfaatan lahan serta pentingnya kesadaran diri sejak kini.  Kata Kunci: Hidrometeorologis, banjir, curah hujan, kawasan terbangun

Abstract

Green Open Spaces (RTH) are urban areas filled with vegetation that support ecological benefits, such as reducing greenhouse gases by absorbing CO₂ through photosynthesis. Although RTH accounts for 66 percent of the area along Jalan Hertasning, its effectiveness in absorbing CO₂ emissions from motor vehicles is not fully understood. Given the high volume of vehicles, especially during peak traffic hours, a deeper understanding of the RTH's capability to reduce CO₂ emissions is necessary. This study aims to measure CO₂ emissions from transportation, assess the RTH's ability to absorb CO₂, and develop effective RTH enhancement strategies. The research location is Jalan Hertasning in Makassar City. The method used in this study is descriptive with a quantitative approach. Results show that CO₂ emissions during peak hours cannot be fully absorbed by the existing 508 Trembles trees, which have a total absorption capacity of 1,652.07 kg/hour and cover an area of 4.4 hectares, or 75.9 percent of Jalan Hertasning. There remains 3,168.59 kg/hour of CO₂ emissions from the total 4,820.66 kg/hour during peak traffic. In addition to Trembles trees, there are other trees like Palm and Terminalia mantaly, which are still growing and not included in this study but could increase the RTH's absorption capacity in the future. The high CO₂ emissions from motor vehicles significantly impact air quality and public health. It is recommended that the government actively conduct environmental awareness campaigns focused on reducing CO₂ emissions and the importance of RTH. These campaigns can be carried out through social media, posters along Jalan Hertasning, and community outreach to reduce CO₂ levels by increasing public participation in maintaining RTH.
