Abstract

ErosionĀ is the main problem that causes land degradation. Erosion causes many problems, such as reduced soil fertility and shallowing of reservoirs, loss of soil nutrients, environmental ecological damage, and decreased agricultural productivity. The Krueng Peusangan watershed has experienced land degradation through flooding, causing erosion. The flooding problem that occurs every year in the Krueng Peusangan watershed, especially in the Krueng Meuh sub-watershed, as a result of the conversion of forest land, impacts the community and the environment. The research aims to map the distribution of erosion areas in the Kreung Meuh Sub-watershed. The research method uses RUSLE spatial analysis. RUSLE analysis uses data on rain erosivity, soil erosivity, slope length, slope, and land use and conservation measures. The research results show that the Krueng Meuh sub-watershed has experienced erosion in light, medium, and heavy categories. Erosion is currently dominating the Krueng Meuh sub-watershed area, which has an area of 4,762.34 ha. Heavy erosion occurred on slopes >15% with an area of 1,675.27 ha. Meanwhile, very light erosion occurs on slopes <8% (flat) with forest land use with an area of 4,224.01 ha and 1,585.48 ha.

Abstract

Hutan lindung saat ini menghadapi permasalahan yang serius yaitu deforestasi. Deforestasi merupakan pengurangan hutan yang disebabkan oleh aktivitas Manusia, sehingga berdampak pada kerusakan lingkungan dan menurunnya fungsi hutan. Penelitian ini bertujuan untuk menganalisis laju deforestasi di kawasan hutan lindung Desa Damaran Baru pada periode 2015 dan 2024. Metode analisis deforestasi dilakukan menggunakan Sistem Informasi Geografis (SIG) dengan overlay intersect yaitu menggabungkan layer penggunaan lahan tahun 2015 dan tahun 2024, untuk menghasilkan layer deforestasi pada kawasan hutan lindung. Hasil penelitian menunjukkan bahwa deforestasi yang terjadi seluas 7,34 Ha. Mencakup penggunaan lahan hutan menjadi jalan seluas 0,01 Ha, hutan menjadi kebun seluas 0,83 Ha, hutan menjadi semak belukar seluas 5,03 Ha, hutan mejadi longsor 1,38 Ha, dan hutan menjadi lahan terbuka seluas 0,09 Ha. Dengan persentase laju deforestasi pada periode 2015 dan 2024 sebesar 3,42%.

Abstract

The problem of riverbank degradation due to erosion and landslides is an important problem in river basin management, especially in the Krueng Meuh Sub-watershed. Bamboo plants have a strong root system and a dense clump structure, so they have great potential in soil and air conservation on riverbanks. This study aims to identify the types of bamboo that grow on riverbanks and analyze their role in riverbank conservation in the Krueng Meuh Sub-watershed. This study is a descriptive exploratory study by exploring the riverbank along 50 meters from the left and right banks of the river. The methods used include direct observation of bamboo morphology, collection of plant characteristic data, and assessment of conservation potential based on clump density and root system strength. The results of the study found five types of bamboo in the Krueng Meuh Sub-watershed, namely Duri Bamboo (Bambusa bluemeana), Talang Bamboo (Schizostachyum Brachcladum), Betung Bamboo (Dendrocalamus asper), Ampel Bamboo (Bambusa vulgaris), and Regen Bamboo (Gigantochloa pruriens). Each species has different morphological characteristics and root systems, and contributes to the stability of riverbanks. The bamboo species with the highest potential in protecting riverbanks are Dendrocalamus asper and Schizostachyum Brachcladum based on root strength and clump density. In conclusion, betung bamboo and talang bamboo have the highest effectiveness in protecting riverbanks due to their deep roots and dense clump structure. Riverbank vegetation management by considering local bamboo species can be an effective and sustainable conservation strategy.
