Distribusi Spasial dan Ketebalan Hutan Mangrove terhadap Intrusi Air Laut di Kecamatan Cilacap Tengah

Introduction

Distribusi spasial dan ketebalan hutan mangrove terhadap intrusi air laut di kecamatan cilacap tengah. Analisis spasial distribusi & ketebalan mangrove Cilacap Tengah terhadap intrusi air laut. Mangrove padat minimalkan intrusi; rekomendasi penanaman penting untuk perlindungan pesisir.

Abstract

Intrusi air laut merupakan salah satu masalah utama yang umum terjadi di wilayah pesisir. Kecamatan Cilacap Tengah merupakan salah satu kecamatan di pesisir selatan Jawa yang diduga mengalami intrusi air laut yang juga memiliki ekosistem hutan mangrove. Hutan mangrove dianggap mampu meminimalisir terjadinya intrusi air laut melalui sistem perakaran, batang, dan daunnya yang mampu beradaptasi dengan air asin. Penelitian ini bertujuan untuk mengetahui pengaruh hutan mangrove terhadpa intrusi air laut yang dilakukan dengan menganalisis distribusi spasial dan ketebalan hutan mangrove terhadap intrusi air laut. Analisis yang digunakan yakni analisis spasial. Hasil penelitian menunjukkan bahwa hutan mangrove tersebar di Kelurahan Kutawaru, Donan, dan Lomanis. Adapun ketebalan hutannya berkisar 0-867,3 m. Hasil pemetaan intrusi air laut menunjukkan bahwa di Kecamatan Cilacap Tengah terdapat daerah yang tidak terintrusi, intrusi sedang, dan intrusi tinggi. Berdasarkan hasil pemetaan di antara keduanya, menunjukkan bahwa di daerah yang bermangrove luas dan tebal tidak mengalami intrusi hingga mengalami intrusi sedang. Sedangkan daerah yang tidak bermangrove dan bermangrove tipis mengalami intrusi sedang hingga tinggi. Sehingga penanaman hutan mangrove harus dilakukan secara lebih merata di lahan-lahan yang tidak bermangrove sama sekali, mengingat keberadaan hutan mangrove berpengaruh terhadap kondisi intrusi air laut di Kecamatan Cilacap Tengah.

Review

This paper addresses a highly relevant environmental issue concerning saltwater intrusion in coastal areas, a challenge exacerbated by climate change and human activities. The study's focus on the role of mangrove forests in mitigating this problem in Kecamatan Cilacap Tengah is commendable, offering a practical ecological solution. The objective to analyze the spatial distribution and thickness of mangroves in relation to saltwater intrusion is clearly stated, and the application of spatial analysis techniques is an appropriate approach for this type of geographical investigation. The abstract effectively introduces the problem, the research setting, and the overarching goal, setting a clear expectation for the full manuscript. The findings presented in the abstract offer valuable insights into the protective capabilities of mangrove ecosystems. The clear distinction between areas with extensive and thick mangrove cover experiencing no to moderate intrusion, versus areas with sparse or absent mangroves facing moderate to high intrusion, strongly supports the hypothesis that mangroves play a critical role in minimizing saltwater intrusion. The identification of specific villages (Kutawaru, Donan, Lomanis) where mangroves are distributed, along with the reported thickness range (0-867.3 m), provides tangible data points. While the abstract states "spatial analysis" was used, a more detailed description of the methods employed for mapping and quantifying intrusion levels would be beneficial for a complete understanding of the rigor and reliability of these findings in the full paper. While the abstract provides a compelling argument for mangrove conservation and restoration, particularly advocating for more even planting in non-mangrove areas, it leaves some questions for the full paper to address. A reviewer would be interested in the specific methodologies used to map and quantify saltwater intrusion, the types of data collected (e.g., salinity levels, hydrological parameters), and the statistical methods employed to establish the correlation between mangrove characteristics and intrusion severity. Exploring other potential confounding factors influencing intrusion, such as groundwater extraction or topography, would also strengthen the analysis. Overall, the study presents a significant contribution to coastal management and mangrove ecology, and a detailed exposition of its methodology and deeper analytical findings will be critical to fully appreciate its scientific merit and practical implications.
