Judul: Kajian tepung bungkil biji karet (TBBK) Hevea brasiliensis sebagai bahan baku pakan benih ikan mas
Abstrak: This research was conducted to study rubber seed meal (Hevea brasiliensis) as a candidate of plant protein source in diet for common carp fry (Cyprinus carpio Linn). This study were divided into 2 experiments: digestibility and growth. Processed rubber seed meal (pRSM) and unprocessed (upRSM) were subjected to digestibility experiment and Cr2O3 at level of 0.05% was used as a tracer. The faeces were daily collected 30-60 minutes after feeding for 14 days. Dry matter, protein, phosphorus and calcium were used as digestibility parameters. Four treatment diets with isoprotein (30%) were used to evaluate growth performance index. Diet P1 have not contained protein come from pRSM. Diet P2 and P3 contained 50 and 75% of protein come from pRSM. Diet P4 contained 50% of protein come from upRSM. Completely randomized design with 4 treatments and 3 replicates were used to this experiment. Common carp fry 2.19 ± 0.005 g was entered to 18 aquariums at 20/aquarium and feed tested diet at satiation for 40 days of culture period. The evaluated parameter were survival rate, feed consumption, feed efficiency, relative growth, protein and lipid retention, water/lipid/glycogen liver content and hepatosomatic index, histological and haematological blood. The result showed that common carp fry relatively better digested pRSM than upRSM. Moreover, the increasing of protein percentage from pRSM until 50% resulted best growth perfomance indicator and haemotological blood parameter. It is concluded that pRSM can be used as protein source up to 50% in diet common carp fry.

Judul: Evaluasi tepung bungkil biji karet Hevea brasiliensis yang difermentasi cairan rumen domba sebagai pengganti bungkil kedelai dalam pakan ikan lele Clarias sp.
Abstrak: The study evaluates the utilization of fermented defatted rubber seed meal (FDRSM) as soybean meal replacement on growth performance of catfish Clarias sp. The effect of FDRSM on feed digestibility was observed as well. A thirty day feeding experiment was performed to observe the effect of partial replacement of defatted soybean meal as protein source by FDRSM. Five isonitrogenous and iso energy of diet were used in this experiment. Diet A all plan protein come from SBM. Diet B, C, D and E soybean meal was replaced by FDRSM at the level of 12, 23, 34, and 44% respectively. Cr2O3 were used as a tracer for measuring digestibility. Fish were fed experimental diet three times dialy at satiation level. Growth and feeding performance of fish fed with diets containing 12-23% FDRSM protein replacement was comparable to that of control. Increasing level of FDRSM to more than 23% resulted in a decreased in growth performance and feed digestibility.
