HUBUNGAN FAKTOR LINGKUNGAN TERHADAP PRODUKSI SERASAH MANGROVE TELING TOMBARIRI, TAMAN NASIONAL BUNAKEN
Abstrak
Penelitian ini bertujuan untuk membandingkan produktivitas ekosistem berdasarkan laju produksi serasah yang dikaitkan dengan jenis pohon dan parameter iklim di Mangrove Teling Tombariri, Taman Nasional Bunaken, Sulawesi Utara. Pengumpulan serasah dilakukan selama 12 bulan di tiga zona penyusun utama mangrove. Serasah kemudian dianalisis berdasarkan fraksi dan jenis. Produksi serasah kemudian dikorelasikan dengan curah hujan, suhu, dan kelembaban udara menggunakan koefisien korelasi sederhana. Korelasi linier antara produksi serasah bulanan fraksi daun, ranting, buah-bunga (fraksi reproduktif) dari setiap spesies mangrove dan parameter iklim bulanan (suhu, curah hujan, dan kelembaban) dihitung dengan menggunakan Korelasi Pearson p<0,01. Hasil menunjukkan bahwa laju produksi serasah di Mangrove Teling Tombariri Taman Nasional Bunaken didapatkan tertinggi pada jenis Sonneratia alba, diikuti oleh Rhizophora apiculata, dan terakhir Bruguiera gymnorhiza. Fraksi serasah terbesar adalah komponen daun, diikuti oleh ranting, dan komponen reproduktif (bunga dan buah), kecuali pada Sonneratia alba di mana fraksi komponen reproduktif lebih tinggi daripada komponen ranting. Selanjutnya faktor lingkungan yang menunjukkan korelasi paling kuat terhadap produksi serasah adalah curah hujan dan hal ini berlaku untuk ketiga jenis penyusun utama Mangrove Teling Tombariri.
