Abstract

AbstrakLatar belakang analisa ini, berbagai jenis penyakit yang dipicu oleh bakteri dan fungi telah banyak menyebar luas terutama di Negara berkembang seperti Indonesia. Penggunaan antibiotik berbahan sintetik seperti ampisilin, kotrimoksasol dan tetrasiklin secara intens dapat menyebabkan kecenderungan terjadinya resistensi galur bakteri patogen. Tujuan penelitian ini untuk mengetahui kandungan iodium yang terdapat Rumput laut (Eucheuma spinosum) serta efektivitas iodium rumput laut terhadap pertumbuhan bakteri Escherichia coli. Metode yang digunakan Titrasi untuk mengetahui kandungan iodium dalam 50 g sampel dengan pelarut Chloroform (CHCl3) dan Disc Diffusion Test ntuk mengetahui peranannya sebagai antibakteri Escherichia coli. Hasil analisa diketahui semakin tinggi kadar iodin atau iodium maka daya hambat bakteri Escherichia coli semakin besar dalam 10  ekstrak. Hasil kadar iodium pada ekstrak Eucheuma spinosum berada pada kisaran 0,38% hingga 1,22%, sedangkan pada Yodor vex (disinfektan hasil pabrik) yang sebagai kontrol positif sebesar 0,38%, dengan menghasilkan diameter zona hambat yang tinggi.Kata kunci: Eucheuma spinosum, Escherichia coli, Antibakteri, Daya hambat.AbstractThe background of this analysis, various types of diseases triggered by bacteria and fungi have spread widely, especially in developing countries like Indonesia. The intense use of synthetic antibiotics such as ampicillin, co-trimoxazole and tetracyclines can lead to a tendency for resistance to pathogenic bacteria. The purpose of this study was to determine the iodine content in seaweed (Eucheuma spinosum) and the effectiveness of seaweed iodine on the growth of Escherichia coli bacteria. The method used is Titration to determine the iodine content in 50 g of sample with Chloroform (CHCl3) solvent and Disc Diffusion Test to determine its role as an antibacterial Escherichia coli. The results of the analysis show that the higher the level of iodine or iodine, the greater the inhibition of Escherichia coli bacteria in 10µl of extract. The yield of crude extract of Eucheuma spinosum was 21% + 53%, while the iodine content was known by different treatments of 0.38% + 1.22%. The content of iodine levels in Eucheuma spinosum seaweed is an effective indicator as an antibacterial for Escherichia coli.Keywords: Eucheuma spinosum, Escherichia coli, Antibacterial, Inhibition.

Abstract

ABSTRAKMakrozoobenthos merupakan salah satu biota yang hidup di ekosistem mangrove, makrozoobenthos berperan untuk membantu mempercepat proses dekomposisi dan mineralisasi materi organik. Tujuan penelitian adalah mengetahui tentang struktur komunitas dan kelimpahan makrozoobenthos di ekowisata mangrove lembung, kecamatan galis, kabupaten pamekasan sehingga diperoleh informasi dan data base dalam pengelolaan yang bekelanjutan. Lokasi penelitian pada ekosistem mangrove di Desa Lembung Kecamatan Galis Kabupaten Pamekasan . Metode penganbilan data menggunakan metode transek dengan analisis datanya menggunakan indeks Shannon-Winner. Nilai tertinggi kelimpahan individu dan relatif adalah spesies Cerithium coralium. indeks ekologi yang didapat menunjukkan kriteria indeks keanekaragaman (H’) sedang, di setiap stasiun, indek keseragaman (E) sedang hingga tinggi dan nilai indeks dominansi (C) rendah, hal ini disebabkan oleh keberadaan biota yang mendominansi daerah Ekowisata Mangrove Lembung sehingga daerah tersebut termasuk pada kriteria stabil.Kata Kunci: Mangrove, Struktur Komunitas, Makrozoobenthos, Desa LembungABSTRACTMakrozoobenthos is one of the biota that lives in mangrove ecosystems, macrozoobenthos plays a role to help accelerate the process of decomposition and mineralization of organic matter. The purpose of the study was to know about the community structure and abundance of macrozoobenthos in lembung mangrove ecotourism, Galis District, Pamekasan Regency so that information and data base are obtained in sustainable management. The location of research on mangrove ecosystems in Lembung Village, Galis District, Pamekasan Regency. The data collection method uses the transect method with data analysis using the Shannon-Winner index. The highest value of individual and relative abundance is the species Cerithium coralium. The ecological index obtained shows the criteria of a moderate diversity index (H'), at each station, medium to high uniformity index (E) and low dominance index (C) value, this is due to the presence of biota that dominates the Lembung Mangrove Ecotourism area so that the area is included in the stable criteria.Keywords: Mangrove, Community Structure, Makrozoobenthos, Lembung Village

Abstract

Binder carboxy methyl cellulose (CMC) biasa digunakan dalam formulasi pakan udang, tetapi mempunyai harga mahal dan tidak memberi dampak terhadap penambahan nutrisi pakan. Penelitian ini bertujuan untuk menemukan bahan binder pengganti CMC yang lebih murah dan memberi dampak penambahan nutrisi dalam pakan udang. Dosis perlakuan binder tepung rumput laut dalam pakan uji sebesar 5% (P1), 10% (P2), 15% (P3), dan 20% (P4). Penelitian ini menggunakan rancangan acak lengkap dengan lima perlakuan dan tiga ulangan, antara lain (P0) binder CMC sebagai kontrol dan (P1-P4) binder tepung rumput laut. Pakan perlakuan diuji kadar air, protein, dan lemaknya dengan metode analisis proksimat. Hasil nilai kadar air pada P0 (3,3%), P1 (3,8%), P2 (4,2%), P3(6%), dan P4 (6,3%), kadar protein pada P0 (40,40%), P1 (28,43%), P2 (40,40%), P3 (32,90%), dan P4 (28,40%), kadar lemak pada P0 (9,97%), P1 (9,98%) dan P1-P4 (9,97%). Penelitian ini menunjukkan bahwa perlakuan penambahan binder CMC dibandingkan dengan perlakuan penambahan binder tepung rumput laut tidak memberikan pengaruh yang nyata terhadap penambahan nutrisi pakan udang. Hasil tersebut membuktikan bahwa tepung rumput laut dapat menggantikan CMC sebagai binder dalam formulasi pakan udang.The binder, carboxy methyl cellulose (CMC), is commonly used in shrimp feed formulations, but it is expensive and has no impact on adding feed nutrition. This experiment aimed to find a binder substitute for CMC that is cheaper and has the effect of adding nutrients to shrimp feed. The doses of binder from seaweed meal treatment in the test feed were 5% (P1), 10% (P2), 15% (P3), and 20% (P4). This study used a completely randomized design with five treatments and three replications, including (P0) CMC binder as a control and (P1-P4) seaweed meal binder. The test feed were tested for water, protein and fat content using the proximate analysis method. Results of water content in P0 (3.3%), P1 (3.8%), P2 (4.2%), P3 (6%), and P4 (6.3%), protein content in P0 (40 .40%), P1 (28.43%), P2 (40.40%), P3 (32.90%), and P4 (28.40%), lipid content in P0 (9.97%), P1 (9.98%) and P1-P4 (9.97%). This experiment showed that the treatment with the addition of CMC binder compared to the treatment with the addition of seaweed meal binder did not have a significant effect on the addition of nutrients to shrimp feed. These results proved that seaweed meal can replace CMC as a binder in shrimp feed formulations.
