Abstract

            Negara Indonesia memiliki potensi sumberdaya kelautan dan pesisir yang kaya, salah-satu diantaranya  adalah rumput laut. Rumput laut di Indonesia masih sebatas dimanfaatkan sebagai sumber makanan dan obat-obatan. Jepang telah memanfaatkan Ulva dan Laminaria sebagai biogas (Matsui et al., 2006), pemanfaatan rumput laut tersebut menunjukkan bahwa rumput laut memiliki potensi sebagai bahan baku biogas. Tujuan dari penelitian ini adalah untuk mengetahui kandungan gas metan yang terkandung pada rumput laut jenis Caulerpa racemosa dan Halimeda macroloba yang di fermentasi secara anaerob. Metode penelitian ini yaitu dengan mencampur rumput laut Caulerpa racemosa dan Halimeda macroloba yang telah dihaluskan dan dilakukan  pencampuran dengan sedimen pantai yang difermentasi anaerob selama 30 hari. Hasilnya yaitu pada Caulerpa racemosa menghasilkan gas metana sebesar 5.13%, dan Halimeda macroloba menghasilkan gas metana sebesar 4.25%. Pupuk NPK digunakan untuk meningkatkan kadar gas metana yang dihasilkan dalam fermentasi anaerob. Konsentrasi pupuk NPK yaitu 2,5 g, 5 g, dan 7,5 g. Hasil dalam penambahan pupuk NPK yaitu kadar gas metana Caulerpa racemosa meningkat 4,45% (persentase peningkatan 64,16%) dan Halimeda macroloba  meningkat sebesar 4,92% (persentase peningkatan 69,18%).

Abstract

Utilization of mangrove seeds is not as popular the use of wood tree. Utilization of wood from mangrove tree is used as raw material for making charcoal and building materials.The local community rarely uses mangrove seeds for food, drinks, scrubs and coloring. This is not enough of public knowledge about the benefits of mangrove seeds. The public mindset that the only sources of carbohydrates are rice and corn. There is not much knowledge about the potential and benefits of mangrove seeds as a coffee drink. The research method used in this research is experimental research. In this experiment, 3 repetitions of treatment and 3 replications. Water content data in the mangrove seed ground coffee was tested by normality test.        The proximate test results show ash content of 1 to 4% when averaged is 2.6%. While the general requirement for roasted coffee (SNI.01.2983-1992) is 7-14% ash content. The color of coffee is influenced by the value of the extract content of the coffee, water soluble coffee juice will give it a deep black color ( Pastiniasih, 2012). The juice content of magrove coffee is high enough for each treatment so that the steeping gives a visually visible black color.
