Monitoring Sebaran Vegetasi Mangrove yang Direhabilitasi di Kawasan Ekowisata Mangrove Wonorejo Surabaya

Kawasan pesisir Wonorejo merupakan kawasan mangrove yang direhabilitasi menjadi kawasan ekowisata. Penelitian bertujuan untuk menganalisis pola pembentukan zonasi vegetasi pada ekosistem mangrove yang telah direhabilitasi. Lokasi pengamatan berada pada 3 stasiun, yaitu Stasiun 1 terletak pada batas atas zona supratidal, Stasiun 2 di pertengahan zona intertidal, dan Stasiun 3 pada zona subtidal. Struktur vegetasi mangrove dianalisis berdasarkan Kerapatan Jenis (K), Dominansi (D), dan Indeks Nilai Penting (INP); sedangkan sebaran vegetasi mangrove berdasarkan karakteristik lingkungan dianalisis dengan menggunakan Analisis Komponen Utama (Principal Component Analysis, PCA). Hasil pengamatan menunjukkan bahwa jenis yang dominan pada Stasiun 1 adalah Nypa fruticans (84,2%), sedangkan pada Stasiun 2 jenis yang dominan adalah Excoecaria agallocha (40,9%), dan di Stasiun 3 adalah Avicennia alba (83,4%). Tingkat kerusakan vegetasi mangrove di Wonorejo dikategorikan sedang, dengan kerapatan pohon antara ≥ 1000 – < 1500 per hektar. Indeks keanekaragaman pada semua stasiun juga tergolong rendah karena bernilai kurang dari 1,5. Ekosistem ini mulai menunjukkan adanya suksesi ekosistem, terbukti dengan mulai adanya jenis-jenis mangrove lain yang tidak ditanam dengan sengaja. Hasil analisis PCA menunjukkan adanya korelasi positif antara parameter jenis vegetasi dengan tinggi rendaman pasut, salinitas, dan pH, yang berkontribusi membentuk sumbu F2 positif. Artinya ketiga parameter tersebut merupakan faktor utama yang menentukan apakah ekosistem tersebut sesuai untuk pertumbuhan jenis mangrove tertentu

The Impact of the Level of the Intestinal Short Chain Fatty Acids in Inflammatory Bowel Disease Patients Versus Healthy Subjects

The aim of this study was to determine the changes of short chain fatty acids (SCFAs) in faeces of inflammatory bowel disease (IBD) patients compared to healthy subjects. SCFAs such as pyruvic, lactic, formic, acetic, propionic, isobutyric and butyric acids were analyzed by using high performance liquid chromatography (HPLC). This study showed that the level of acetic, 162.0 µmol/g wet faeces, butyric, 86.9 µmol/g wet faeces, and propionic acids, 65.6 µmol/g wet faeces, decreased remarkably in IBD faecal samples when compared with that of healthy individuals, 209.7, 176.0, and 93.3 µmol/g wet faeces respectively. On the contrary, lactic and pyruvic acids showed higher levels in faecal samples of IBD than in healthy subjects. In the context of butyric acid level, this study also found that the molar ratio of butyric acid was higher than propionic acid in both faecal samples. This might be due to the high intake of starch from rice among Malaysian population. It was concluded that the level of SCFAs differ remarkably between faecal samples in healthy subjects and that in IBD patients providing evidence that SCFAs more likely play an important role in the pathogenesis of IBD
