Feed utilization efficiency is one of the problems that often faced by tiger shrimp (Penaeus monodon Fabricus) farmers, which is 40-60% of production costs used for feed. The efficiency of feed can be improved by the addition of the bromelains in the feed, which can hydrolyze proteins into simpler compounds to increase the digestibility of the feed protein. This study aims to examine the effect of bromelains in feed on protein digestibility (ADCp), feed utilization efficiency (EPP), and growth (RGR) of tiger shrimp. Tiger shrimp with an average weight of 2.8 ± 0.26 g / individual was obtained from the Brackish Water Aquaculture Development Centre (BBPBAP), Jepara. There were 6 treatments adding bromelains in the feed, A (0%), B (0.2%), C (0.4%), D (0.6%) and E (0.8%). Observation parameters, including ADCp, EPP, PER, RGR, SR, and water quality parameters. The results showed that the addition of the bromelains in feed increased ADCp, EPP, PER, RGR, but had no effect on the SR of tiger shrimp. Bromelains (0.4% / kg) of feed is the optimal dose of ADCp, EPP, and RGR, resulting in a maximum value of 82.59%, 88.17%, and 5.24% / day. Permasalahan yang sering dihadapi pembudidaya udang windu (Penaeus monodon Fabricius) adalah efisiensi pemanfaatan pakan yang belum maksimal sehingga hampir 40-60% dari total biaya produksi untuk biaya pakan. Efisiensi pemanfaatan pakan dapat ditingkatkan dengan penambahan enzim bromelin dalam pakan yang mampu menghidrolisis protein menjadi senyawa yang lebih sederhana sehingga dapat meningkatkan daya cerna protein pakan. Penelitian ini bertujuan mengkaji pengaruh enzim bromelin dalam pakan terhadap kecernaan protein (ADCp), efisiensi pemanfaatan pakan (EPP) dan pertumbuhan (RGR) udang windu. Hewan uji berupa udang windu dengan bobot rata-rata 2,8±0,26 g/ekor diperoleh dari Balai Besar Perikanan Budidaya Air Payau (BBPBAP), Jepara sebagai tempat penelitian. Terdapat 6 perlakuan penambahan enzim bromelin dalam pakan yaitu A (0 %), B (0,2 %), C (0,4 %), D (0,6 %) dan E (0,8 %). Pengamatan parameter meliputi ADCp, EPP, PER, RGR, SR dan parameter kualitas air. Hasil penelitian menunjukkan bahwa penambahan enzim bromelin dalam pakan meningkatkan ADCp, EPP, PER, RGR, namun tidak berpengaruh pada SR udang windu. Enzim bromelin 0,4%/kg pakan merupakan dosis optimal pada ADCp, EPP dan RGR menghasilkan nilai maksimal sebesar 82,59%, 88,17% dan 5,24%/hari.

White Kakap (Lates calcalifer) is a superior commodity and has a high nutritional value. Growth factors are hampered by the ineffectiveness of the digestive process. Protease is an enzyme capable of hydrolyzing peptide bonds in proteins. Feed is a factor that predominantly affects the growth of fish because feed serves as a supplier of energy to support growth. Protein digestion in aquatic animals requires proteases as a catalyst. Enzymes that play an important role in the process of protein digestion are proteases. The purpose of this study is to examine the effect of adding different protease enzymes to artificial feed on the efficiency of protein utilization in the growth of white snapper (Lates calcalifer). The results of this study are expected to provide information about the importance of protease enzyme application in artificial feed in increasing protein hydrolysis, so that protein can be easily utilized by the body of white snapper (Lates calcalifer). The cultivars tested were white snapper (Lates calcalifer). The cultivation comes from intensively cultivated Lampung with an average weight of 6.5 ± 0.44 g / tail with a length ranging from 4-5 cm, as many as 75 heads.

Availability of diet in Sangkuriang catfish (Clarias gariepinus) cultivation is becoming a main concern. One of the problems in the artificial diet is that the protein content could not fully be utilized by the catfish. To solve the problem is by adding papain protease in the artificial diet. This study was conducted to evaluate the effect of papain protease enzyme in artificial diet on diet utilization efficiency and growth performance of sangkuriang catfish (Clarias gariepinus) fingerlings in the Village of Tambaksari, Sub-district of Rowosari, District of Kendal, and Central Java. The fingerlings with initial body weight averaging 4.23±0,30 g were cultivated with the density of 1 fingerling per liter. The fingerlings were obtained from Center for Hacthery, Muntilan. The fingerlings were fed with artificial diet in four different doses of papain enzyme: A (0%), B (0.75%), C (1.5%), and D (2.25%). The experiment used Complete Random Design with 4 (four) treatments and each treatment replicated 3 (three) times. The results show that the addition of papain protease enzyme significantly (P<0.01) affected on the spesific growth rate (SGR) and net protein utilization (NPU). It could be concluded that the addition of papain protease enzyme could increase the specific growth rate (SGR) and net protein utilization (NPU) of Sangkuriang catfish (Clarias gariepinus) fingerlings. Optimum papain protease enzyme dose on the specific growth rate was 2.25% per kg diet. The water quality during study was still in the viable ranges for Sangkuriang catfish (Clarias gariepinus) fingerlings cultivation.Key word: papain protease enzyme, artificial diet, growth, sangkuriang catfish fingerlings
