Abstract

Di Indonesia, hutan-hutan mangrove terbaik terdapat di pantai barat daya Papua sekitar Teluk Bintuni yang mencapai luas 1,3 juta ha, yang merupakan sepertiga dari luas hutan mangrove Indonesia, sedangkan sisanya terdapat di pantai utara Jawa, pantai timur Sumatra, dan pantai barat serta selatan Kalimantan. Keberadaan hutan mangrove amatlah penting dikarenakan mempunyai peran ganda disamping memiliki potensi ekologis dan juga memberikan manfaat ekonomi bagi kesejahteraan masyarakat disekitarnya. Salah satu Hutan Mangrove yang masih tersisa terdapat di kawasan konservasi Cagar Alam Teluk Apar Kabupaten Paser Kalimantan Timur. Ekosistem Hutan Mangrove digambarkan sebagai biodiversitas dengan berbagai vegetasi dan satwa liar yang hidup dikawasan cagar alam. Berdasarkan data dan informasi Balai Konservasi Sumberdaya Alam bahwa terdapat 25 jenis mangrove sejati dan 13 famili dan 14 jenis mangrove ikutan dari 13 famili sebagai penyusun hutan mangrove. Terdapat 2 jenis langka secara global namun tidak secara lokal yaitu Tagal (Ceriops decandra) dan Perpat Merah (Schippyphora hidrophylaceae). Sedangkan Satwa Liar jenis mamalia yang terdapat di Area Konservasi Cagar Alam Teluk Apar yaitu Bekantan (Nasalis larvatus), Elang Bondol (Haliastur indus), Bangau Tongtong (Leptoptilus javanicus), Pecut Ular (Anhinga melanogaster) dan Buaya Muara (Crocodylus porosus).

Abstract

Penelitian ini bertujuan untuk melihat pengaruh ekstrak inulin dari bawang merah (Allium cepa Linn.) terhadap pertumbuhan bakteri probiotik Lactobacillus acidophilus. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas satu kontrol dan tiga perlakuan, yaitu medium Lactobacilli MRSB + bakteri Lactobacillus acidophilus sebagai kontrol (A0), serta  pemberian ekstrak inulin dengan konsentrasi 2500 ppm (A1), 5000 ppm (A2), dan 10.000 ppm (A3). Teknik pengumpulan data dilakukan melalui pengamatan dan perhitungan jumlah sel dengan menggunakan metode Standart Plate Count (SPC). Parameter yang diamati adalah pertambahan jumlah sel Lactobacillus acidophilus pada medium Lactobacilli MRSA setelah memperoleh nutrisi dari medium Lactobacilli MRSB dengan berbagai konsentrasi. Data yang diperoleh dari hasil pengamatan dianalisis dengan menggunakan sidik ragam Rancangan Acak Lengkap (RAL) pada taraf kepercayaan α = 0,05. Hasil penelitian menunjukkan bahwa pemberian inulin ke dalam medium Lactobacilli MRSB dalam penelitian ini ternyata dapat berpengaruh positif terhadap pertumbuhan bakteri Lactobacillus acidophilus. Pertumbuhan terbaik bakteri Lactobacillus acidophilus terdapat pada penambahan konsentrasi inulin 10.000 ppm dibandingkan dengan penambahan inulin dengan konsentrasi 5000 ppm, 2500 ppm dan 0 ppm (kontrol). Semakin tinggi konsentrasi inulin maka semakin tinggi tingkat pertumbuhan bakteri Lactobacillus acidophilus.
