Judul: Nilai Hematologi, Frekuensi Jantung, Respirasi, Dan Suhu Tubuh Domba Jantan Yang Mnegonsumsi Pelet Daun dan Campuran Batang Lunak Katuk Depolarisasi
Abstrak: Pemberian pelet katuk depolarisasi sebagai feed additive pada hewan ruminansia sudah popular dikalangan peternak. Penelitian ini bertujuan untuk mengevaluasi respon fisiologis dan hematologi domba jantan masa tumbuh yang diberikan pelet daun dan campuran batang lunak katuk Depolarisasi (15%). Dua puluh satu (21) ekor domba lokal jantan masa tumbuh, dikelompokkan menjadi 7 kelompok masing-masing 3 ekor. Pengelompokan berdasarkan perlakuan bahan baku daun katuk (D) dan campuran batang lunak 15% dengan daun katuk 85% (DBL), serta dosis pemberian pelet secara oral setiap hari yaitu D-1 5gram, D-2 10gram dan D-3 15gram, DBL-1 5gram, DBL-2 10gram, DBL-3 15gram. Parameter yang diamati adalah frekuensi jantung, respirasi, suhu tubuh, kadar hemoglobin, hematokrit, jumlah eritrosit dan leukosit serta persentase diferensiasi leukosit yang terdiri dari limfosit, monosit, neutrofil, basofil, eosinofil dan rasio N/L. Penelitian ini menunjukkan Pemberian pelet D dan DBL tidak mempengaruhi nilai hematologi domba jantan. Nilai hematologi, frekuensi jantung, respirasi dan suhu tubuh masih dalam kisaran normal dan rasio N/L menunjukkan nilai yang masih wajar. Penelitian ini menyimpulkan bahwa penggunaan kedua bentuk pelet tersebut pada domba jantan masa tumbuh tidak menunjukkan adanya pengaruh fisiologis dan tidak menunjukkan tanda-tanda domba dalam kondisi stress. Substitusi batang lunak 15% sebagai bahan baku pelet sangat dimungkinkan dan tidak menggangu fisiologis domba. Kata kunci: Domba, pelet, daun katuk, fisiologis, hematologi, Giving depolarizing katuk pellets as a feed additive to ruminants has been popular among breeders. The aim of this study was to evaluate the physiological and hematological responses of growing rams that is given katuk leaf pellets and a mixture of depolarized katuk soft stems (15%). Twenty-one (21) young local rams were grouped into 7 groups of 3 each. The grouping was based on the treatment of pellet where (D) contains katuk leaf as the main ingredients and (DBL) contains a mixture of 15% soft stems with 85% katuk leaf, based on the dose that is given via oral, namely D-1 5gram, D-2 10gram and D-3 15gram, DBL -1 5grams, DBL-2 10grams, DBL-3 15grams. Observed Parameters were heart frequency, respiration, body temperature, hemoglobin and hematocrits levels, erythrocyte and leukocyte counts and the percentage of leukocyte differentiation consisting of lymphocytes, monocytes, neutrophils, basophils, eosinophils and the N/L ratio. This study showed that D and DBL pellets did not affect the hematological value of rams. Hematologic values, heart rate, respiration and body temperature were still in the normal range and the N/L ratio showed reasonable values. This study concluded that the use of these two forms of pellets in growing rams did not show any physiological effect and did not show signs of sheep under stress conditions. Substitution of 15% soft stem as raw material for pellets is very possible and does not disturb the sheep's physiology. Keywords: Sheep, pellets, katuk, physiological, hematology

Judul: Growth and Digestibility in Rams Consuming Katuk Leaves Pellet and Mixed Soft Stem with Depolarized Katuk Leaves Pellet
Abstrak: Bahan baku produksi imbuhan pakan pelet katuk depolarisasi masih mengandalkan daun katuk, belum ada upaya memanfaatkan batang lunak sebagai substitusi bahan baku. Penelitian ini bertujuan mengetahui respon pemberian pelet daun katuk (D) dan pelet campuran batang lunak dengan daun katuk (DBL) dalam berbagai dosis terhadap pertumbuhan bobot badan dan kecernaan pakan. Sebanyak 21 ekor domba jantan lokal masa tumbuh diberi pakan rumput lapang dan konsentrat, dibagi menjadi 7 kelompok perlakuan masing-masing terdiri atas tiga ekor domba, yaitu kelompok kontrol, pelet daun katuk 5 g (D1), 10 g (D2), 15 g (D3), dan pelet campuran batang lunak dengan daun katuk 5 g (DBL1), 10 g (DBL2), 15 g (DBL3). Pemberian pakan perlakuan sesuai dosisnya, dilakukan setiap hari selama 10 minggu. Pengukuran parameter dilakukan terhadap pertambahan bobot badan (PBB) dan pertambahan bobot badan harian (PBBH), serta kecernaan pakan. Penelitian ini menunjukkan bahwa pemberian pelet daun katuk (D) 10 dan 15 g serta pelet campuran batang lunak dengan daun katuk (DBL) 15 g mampu meningkatkan PBB dan PBBH domba jantan. Pemberian pelet campuran batang lunak dengan daun katuk (DBL) 15 g mampu meningkatkan kecernaan lemak kasar hingga 94,09 ± 0,61%. Substitusi batang lunak dalam pelet daun katuk dapat digunakan sebagai bahan baku pelet katuk depolarisasi., The raw material for depolarized katuk pellets (Katulac®) production still relies on katuk leaves, katuk soft stems never been used as a substitution. This research designed to determine administration response of katuk leaves pellet (D) and a mixture of soft stems with katuk leaves pellet (DBL) in various doses to body weight gain (PBB) and digestibility. Experimental animals were 21 local rams which fed with grass and concentrate, divided into 7 groups that consisted of three rams, namely: control group (control), katuk leaves pellet 5 g (D1), 10 g (D2), 15 g (D3), and mixture of soft stems with katuk leaves pellet 5 g (DBL1), 10 g (DBL2), 15 g (DBL3). The treatment given every day in 10 weeks according to the doses. Parameter measurements were on body weight gain (PBB), daily body weight gain (PBBH), and feed digestibility. The study showed that giving pellet (D) 10 and 15 g and (DBL) 15 g could increase PBB and PBBH of rams. Pellet (DBL) 15 g administration showed a crude fat digestibility in the value of 94.09 ± 0.61%. It’s still possible to substitute soft stems as raw material in depolarized katuk pellets.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
