| Judul Artikel | Analisis Struktur Vegetasi Riparian Dan Hubungannya Terhadap Kualitas Air Di Sungai Logawa |
| Abstrak (Bhs. Indonesia) | Vegetasi riparian berperan penting dalam menjaga kualitas air sungai. Penelitian ini bertujuan untuk mengkategorikan komposisi dan struktur vegetasi riparian, mengidentifikasi kualitas air Sungai Logawa, serta menjelaskan hubungan antara vegetasi riparian dan kualitas air. Metode yang digunakan adalah purposive sampling dan nested sampling pada 12 stasiun (4 hulu, 4 tengah, 4 hilir) dengan plot berukuran 10×10 m (pohon), 5×5 m (tiang), dan 1×1 m (semai). Sebanyak 32 spesies dari 21 famili ditemukan dengan total 1.005 individu. Spesies dominan pada masing-masing strata adalah Tectona grandis, Falcataria moluccana, dan Aspilia mossambicensis. Nilai indeks Menhinick tinggi dan indeks Jaccard rendah, menunjukkan kekayaan spesies yang tinggi dan kesamaan antar stasiun yang rendah. Distribusi vegetasi cenderung mengelompok. Analisis Canonical Correspondence Analysis (CCA) menunjukkan hubungan erat antara keberadaan vegetasi dengan parameter kualitas air (suhu, pH, DO). |
| Abtrak (Bhs. Inggris) | Riparian vegetation plays an important role in maintaining river water quality. This study aims to categorize the composition and structure of riparian vegetation, identify the water quality of the Logawa River, and explain the correlation between riparian vegetation and water quality. The methods used were purposive sampling and nested sampling at 12 stations (4 upstream, 4 midstream, and 4 downstream) with plots measuring 10×10 m (trees), 5×5 m (poles), and 1×1 m (seedlings). A total of 32 species from 21 families were found, with a total of 1,005 individuals. The dominant species in each stratum were Tectona grandis, Falcataria moluccana, and Aspilia mossambicensis. The Menhinick index value was high and the Jaccard index was low, indicating high species richness and low similarity between stations. Vegetation distribution tended to be clustered. Canonical Correspondence Analysis (CCA) showed a close correlation between vegetation presence and water quality parameters (temperature, pH, DO). |
