Abstract

ABSTRAK Pakan yang sesuai dengan tingkat kebutuhan nutrisi dan memiliki nilai kecernaan yang tinggi dapat mendukung pertumbuhan optimum dari ikan.  Papain merupakan enzim protease dari getah papaya yang mampu meningkatkan daya cerna dan penyerapan protein oleh ikan atas pakan yang dikonsumsi, sehingga meningkatkan pemanfaatan pakan oleh tubuh.  Penelitian ini bertujuan untuk mengkaji pengaruh papain dalam pakan buatan terhadap tingkat pemanfaatan protein pakan dan pertumbuhan lele dumbo (Clarias gariepinus).  Variabel yang dikaji meliputi nilai efisiensi pemanfaatan pakan (EPP), protein efisiensi rasio (PER), laju pertumbuhan relatif (RGR), dan kelulushidupan (SR). Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu perlakuan A (papain dosis 0%), B (papain dosis 0,75%), C (papain dosis 1,5%), dan D (papain dosis 2,25%).  Hasil penelitian menunjukkan bahwa perlakuan D memberikan nilai EPP dan PER tertinggi (P<0,05), yaitu masing-masing sebesar 62,83±3,48 dan 1,97±0,11%.  Nilai RGR pada perlakuan D, B, dan C adalah sama (P>0,05), namun lebih tinggi bila dibandingkan dengan perlakuan A.  Berdasarkan pada hasil penelitian dapat disimpulkan bahwa papain dalam pakan mampu meningkatkan nilai EPP, PER, dan RGR pada benih lele dumbo (C. gariepinus).ABSTRACT The fish feed that matched with nutritional requirement and has high value of digestion values will be able to promote optimum growth of fish.  Papain is protease enzim from papaya sap.  It is able to increase the digestion rate and protein absorption of the feed consumed, so it increase the feed utility by the fish. The purpose of the research was to observe the effects of dietary papain on dietary protein utility rate and growth of the African catfish (C. gariepinus).  The variables measured were feeding efficiency (FE) value, protein efficiency ratio (PER), relative growth rate (RGR), and survival rate (SR).  This research use completely randomized design (CRD) with 4 treatments and 3 replicates, i.e. treatment A (0% papain), B (0.75% papain), C (1.5% papain), and D (2.25% papain). Data showed that the treatment D resulted on the highest values on FE and PER (P<0.05), that were 62.83±3.48 and 1.97±0.11%.  The value of RGR in treatments D, B, and C were similar (P>0.05), but was higher than treatment A.  It was suggested that the used of papain in practical diet was able to increase the FE, PER, and RGR values for the African catfish fingerlings (C. gariepinus).

Abstract

Apple consist of some chemical compound like ellagic acid and quinon. Apple tissue also has peroxidase that can be change into hydrogen peroxide with to help catalase. Hydrogen peroxide is on chemical compound that usually used for tooth whitening (bleaching). Ellagic acid also can be used for tooth whitening with the similiar chemical reaction of hydrogen peroxide. This research is to know do apple extract (Malus Sylvestris) have eflect to the degree of tooth colour changing of bleaching process.The design of this research is laboratory experimental an in vitro with 15 non vital tooth as sample. This research use apple extract 100% (test group), hydrogen peroxide 10% (positive control group), and aquades (negative control group). Those 3 materials were put into 3 different glasses with 30 ml volume and each 5 tooth were inserted into each glass. The tooth lighted with spectrophotometer before the soaked. Then tooth were soaked for 96 hours (4 days). After the soaked, the tooth lighted again for counting the degree of tooth colour change based on the result from the spectrophotometer.The result of the statistic test use paired t-test shows that there was significant differences in tooth colour change in three of the test. Value from apple extract 100%p=0, 02, hydrogen peroxide I 0%p=0, 00 and aquades p=0, 03 (p 0, 05). Based on the statistic result, can concluded that apel apple extract can the degree of tooth colour change or changing oftooth colour to be whiter (brighter), after soaked for 96 hours (4 days). Acid component in the apple use in high concentration and long time can damage tooth email and tooth porosity.

Abstract

Ikan Patin (Pangasius sp.) merupakan komoditas air tawar yang memiliki nilai ekonomis penting dalam ruang lingkup akuakultur. Kualitas air menjadi salah satu perhatian utama para pembudidaya karena ikan patin merupakan salah satu jenis ikan yang banyak menghasilkan limbah budidaya. Hal tersebut tentu berpengaruh  terhadap pertumbuhan dan kelulushidupan patin yang dibudidayakan. Probiotik merupakan mikroorganisme yang memiliki kemampuan untuk meningkatkan kualitas perairan, memicu pertumbuhan dengan meningkatkan kemampuan sistem pencernaan dan meningkatkan nilai kelulushidupan pada patin. Penelitian ini bertujuan mengkaji pengaruh penggunaan probiotik dengan dosis yang berbeda dalam media pemeliharaan terhadap kualitas air, pertumbuhan dan kelulushidupan benih patin. Volume wadah yang digunakan dalam penelitian ini adalah 50 Liter. Ikan uji yang digunakan adalah benih patin berukuran 5-7 cm dengan bobot rata-rata 1,99±0,01 g/ekor. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 kali pengulangan. Perlakuan A tanpa pemberian probiotik/kontrol, perlakuan B dengan dosis 1 ml/L, perlakuan C 2ml/L, dan perlakuan D 3ml/L. Hasil penilitian menunjukkan bahwa penambahan probiotik dalam media pemeliharaan benih patin memberikan pengaruh yang nyata (P<0,05) terhadap kualitas air, pertumbuhan dan kelulushidupan benih patin. Perlakuan terbaik pada perlakuan D dosis 3ml/L dengan nilai amonia dan nitrit terendah yaitu 0,093±0,028 mg/L dan 0,040±0,018 mg/L. Nilai pertumbuhan terbaik yaitu bobot mutlak 8,44±0,09 g, nilai SGR 3,94±0,03 %/hari, FCR 1,77±0,06 dan SR 83,3±0,58%. Hasil studi ini diharapkan dapat memberikan informasi dasar mengenai efektifitas penggunaan probiotik dalam memperbaiki kualitas air pada budidaya skala komersil.
