Abstract


Indonesia merupakan salah satu pusat keanekaragaman hayati laut termasuk untuk karang. Hal tersebut adalah potensi dan tantangan seiring meningkatnya degradasi ekosistem karang dari waktu ke waktu. Saat ini keindahan ekosistem karang beserta biota yang berasosiasi dengannya dapat dinikmati diluar habitat aslinya dengan adanya akuarium air laut sehingga karang menjadi komoditas dengan nilai ekonomi yang cukup tinggi. Permintaan telah menjadikan Indonesia sebagai salah satu negara pengekpor karang hias terbesar di dunia. Seiring dengan hal tersebut teknologi pendukung akuarium air laut terus berkembang sesuai dengan berbagai tujuan penggunaan. Makalah ini mendeskripsikan desain sistem resirkulasi modular untuk karang yang dapat dimanfaatkan sebagai media edukasi, penampungan karang hias, budidaya, pariwisata, riset, konservasi ataupun sekedar hobi. Komponen-komponen pada sistem resirkulasi meliputi bak pemeliharan, bak-bak filtrasi, filter (fisik, mekanis dan biologis), pemipaan, pengaturan suhu air, mekanisme arus dan sirkulasi (pompa) yang saling terhubung serta dapat di bongkar pasang dan dipindahkan dengan mudah. Adapun peralatan pendukung berupa pencahayaan buatan dengan LED dan termometer untuk pemantauan suhu air. Sistem dapat digunakan untuk bak pemeliharaan berkapasitas hingga 900 liter air laut. Filter mekanis menggunakan protein skimmer dan fluidized media reactor sedangkan filter biologis dengan live rock dan bioball ataupun bioring. Desain sistem resirkulasi juga dapat diaplikasikan menggunakan refugium ataupun filter live sand dengan beberapa penyesuaian. Perancangan dengan sistem modular menjadi alternatif, memberikan kemudahan dan fleksibilitas pemasangan serta pemilihan bahan bagi siapa saja yang akan membangun akuarium air laut terutama untuk karang.
