The objective of this study was to measure the effect of preparation the shrimp head waste to poultry feed. The experiment was conducted to examine the effect of soaking and steam heat treatment of shrimp heads waste (SHW) on nutrient and nutritional quality. The treatment is soaking and length of steam heat the shrimp heads waste. The experiment was designed in Completely Randomized Design, using factorial (3 x 3) with three replication. The first factors was three level concentration of the dusk rice solution (C1 = 10%; C2 = 20%; and C3 =30%), and the second factors was length steam heat (W1 = 30 min; W2 = 45 min; and W3 = 60 min). Feed was soaked for 48 h prior to steam heat. The results showed that there was no interaction effects (P > 0.05) between concentration of the dusk rice solution and length of steam heat to dry matter (DM), crude protein (CP), lipid and fiber contents of SHW but length of steam factors was significant (P<0.05) to dry matter, crude protein, lipid and fiber contents of SHW and digestibility coefficient (in-vitro) of crude protein. There were interactions (P<0.01) concentration of the dusk rice solution and length of steam factors to chitin contents. There are no significant differences on metabolizable energy but nitrogen retention and protein digestibility was found to be significantly (P<0.05) between the SHW processed than unprocessed. Based on comparative cost analyses and nutritive value indicated, the best treatment was filtered of the dusk rice solution with concentratin 20 % and length of steam heat for 45 min.

The low activity and cognitive learning outcomes of Grade VIIIB MTs Aisyiyah students require innovation in learning by using cooperative learning models. This study aims to determine the increase in activities and learning outcomes in biology through the application of cooperative learning models of students team achievement division class VIIIB MTs Aisyiyah Sungguminasa Kab. Gowa. This type of research is Classroom Action Research which consists of two cycles. The subjects of the study were students of class VIIIB MTs Aisyiyah Sungguminasa Kab. Gowa. The research instrument was an observation sheet and a test. Data analysis techniques with qualitative descriptive statistical analysis for student activities and analyzed with quantitative descriptive statistical analysis for learning outcomes. The results showed that there was an increase in students' cognitive learning activities and outcomes namely from cycle 1 and cycle 2 with an average value of 46.71% and 85.5%. Thus, the conclusion of this research is the use of cooperative learning models of students team achievement division type can increase the activities and learning outcomes of students of class VIIIB MTs Aisyiyah Sungguminasa Kab. Gowa.

The objective of this study was to determine the effect of varying levels of cattle rumen fluid obtained from abattoirs as sources of a crude enzyme on growth performances and carcass characteristics of Kerinci ducks fed rations based on local feed ingredients. The research was carried out using 140 one-week-old male Kerinci ducks. The experiment used a randomized block design consisted of 5 treatments, each with 4 replicate groups and was blocked based on body weight, while each cage unit consisted of 7 ducks. The treatments applied were R1= 0 mL RFS/kg ration (control), R2= R1 + 22 mL RFS/kg ration, R3= R1 + 44 mL RFS/kg ration, R4= R1 + 66 mL RFS/kg ration, and R5= R1 + 88 mL RFS/kg ration. The experimental ducks were fed the experimental ration for 7 weeks and fed ad libitum according to the treatment. At the end of the 7th weeks of treatment, two ducks from each cage were slaughtered and utilized for analysis of carcass and digestive organs parameters. The results showed that the addition of RFS up to a level of 88 mL/kg ration had no significant effect (p>0.05) on feed consumption, feed conversion, carcass weight, and digestive-organ weight. Still, it had significant effects on body weight gain and final body weight. The highest body weight gain and final body weight were achieved with the addition of RFS at the level of 88 mL/kg ration. It can be concluded that the addition of cattle rumen-fluid supernatant as a source of crude enzymes at the level of 88 mL/kg ration improved the growth performance of local Kerinci ducks.

Penelitian ini bertujuan untuk mengetahui level limbah udang terfermentasi dengan Probio – FM dalam ransum ternak sapi. Limbah udang terfermentasi dipergunakan sebagai pengganti konsentrat dengan level 0; 10; 20 and 30 % dari total konsentrat yang digunakan. Perbandingan hijauan dan konsentrat dalam ransum adalah 60:40. Rancangan yang digunakan dalam penelitian adalah Rancangan Acak Kelompok dengan 4 perlakuan dan 3 ulangan. Peubah yang diamati terdiri dari ransum masuk (nutrient feed intake) dan pertambahan bobot badan. Hasil dari penelitian menunjukkan bahwa perlakuan berpengaruh nyata (P<0.05) terhadap nutrient feed intake dan pertambahan bobot badan). Pemasukan tertinggi adalah 3.765 kg ekor-1 hari-1) dan pertambahan bobot badan (829.4 g ekor-1 hari-1) dapat dicapai dengan pemberian 10 % fermentasi limbah udang. Kesimpulan dalam penelitian ini adalah bahwa penggantian 10% konsentrat dengan limbah udang terfermentasi memberikan produksi tertinggi terhadap zat makanan masuk dan pertambahan bobot badan ternak sapi Kata Kunci : limbah udang terfermentasi, sapi, masukan makanan feed intake), pertambahan bobot badan

Mayoritas masyarakat di Mendahara ilir berprofesi sebagai nelayan Sondong merupakan alat tangkap yang banyak dioperasikan oleh nelayan di Mendahara ilir.
