Abstract

The study on macrobenthic community structures was carried out in the offshore area of Mimika district, Papua in 2005. Steep mountain slopes and some of the highest rainfall rates in the world, have generated tremendous sediment loads that have settled in the alluvial plain and been carried out into the estuaries and the Arafura Sea, creating a massive area of deposited natural sediments. The objective of this study was to determine how the benthic community structures of the offshore area (Arafura Sea) changes as a result of environmental conditions. To accomplish the objective, samples were collected from 40 stations which were divided into 4 contours (layers) of water depth, i.e. 5, 10, 20 and 40 m. Stations of each contour depth were established perpendicular to the river mouths of Mimika district. The results showed the bottom sediments were mostly silt-clay fractions except the deeper area (40 m depth) which was dominated by very fine sand fraction. Diversity indices, Shannon index (H) and Pielous evenness (e) index ranged from 1.00-3.50 and 0.20-0.92 respectively. These indices tended to increase in the deeper areas. In total 266 species of macro-benthos were collected from the study area. Contrary to this, the densities tended to decrease in deeper areas with the range of 195.00 — 4110.00 individualsm-2. Polychaetes was the the dominant group, 50.80 — 71.80 % of the total family of macrobenthos. Among the macrobenthos, there were some families and group of taxa which had high densities such as Sipuncula, Nemertea and crustaceans including Ampeliscidae, Gammaridae and Israeidae. Among the polychaete group were the families Spionidae, Owenidae, Sternaspidae, Cossuridae, Capitellidae, Nephtyidae, Magelonidae and Pilargidae. Based on density, macrobenthos of the study area shows relatively high production. High rates of sedimentation of Ajkwa estuary does not influence the structure of macrobenthic communities in the offshore area.

Stations of each contour depth were established perpendicular to the river mouths of Mimika district. The results showed the bottom sediments were mostly silt-clay fractions except the deeper area (40 m depth) which was dominated by very fine sand fraction. Diversity indices, Shannon index (H') and Pielou's evenness (e) index ranged from 1.00-3.50 and 0.20-0.92 respectively. These indices tended to increase in the deeper areas. In total 266 species of macro-benthos were collected from the study area. Contrary to this, the densities tended to decrease in deeper areas with the range of 195.00 ? 4110.00 individualsm-2. Polychaetes was the the dominant group, 50.80 ? 71.80 % of the total family of macrobenthos.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan multienzim dalam ransum yang mengandung bungkil inti sawitterhadap performa pertumbuhan dan morfometrik usus halus pada broiler.Penelitian menggunakan 112 ekor DOC broiler, multienzim komersil Solagri-3 yang merupakan kombinasi beberapa enzim unggulan, yaitu enzim amylase, cellulase, glukanase, pectinase, phytase, protease dan xilanase.Ransum disusun dengan kandungan bungkil inti sawit sebanyak 30% dan disuplementasi dengan 3 (tiga) level multienzim Solagri-3 yaitu 0.03%, 0.06% dan 0.09%. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan, tiap ulangan terdiri dari 7 ekor ayam. Perlakuan yang diujikan terdiri dari; P0= Ransum basal (kontrol), P1= P0 + 0.03% Solagri-3, P2= P0+ 0.06% Solagri-3 dan P3= P0+ 0.09% Solagri-3. Peubah yang diamati adalah konsumsi ransum, pertambahan bobot badan, konversi ransum, karkasrelatif, persentase hati,pancreas, gizard, bobot dan panjangusus halus sertabagian-bagiannya. Data dianalisis sesuai rancangan dan jika terdapat pengaruh yang nyata akan dilanjutkan dengan Uji Duncan (Steel dan Torrie, 1993). Hasil analisis ragam menunjukkan bahwa penambahan multienzim berpengaruh tidak nyata (P>0.05) terhadap konsumsi, pertambahan bobot badan, konversi ransum, persentase hati, pancreas dan gizzard. Penambahan multienzim berpengaruh nyata (P<0.05) terhadap bobot karkas, persentase bobot dan panjang usus halus. Uji Duncan menunjukkan bahwa penambahan multienzim Berpengaruh nyata (P<0.05) dapat meningkatkan bobot relatif karkas, persentase bobot dan panjang usus halus. Kesimpulan dari penelitian ini adalah penambahan multienzim solagri-3 dalam ransum yang mengandung BIS 30% sebanyak 0.06% dalam ransum dapat meningkatkan bobot karkas dan usus halus pada broiler.
