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: Profile of Raw Materials of Katuk Depolarization and Palatability of Katuk Feed Additive on Sheep and Cattle
Abstrak: Daun tanaman katuk (Sauropus androgynus (L.) Merr) sebagai obat atau imbuhan pakan (feed additive) dapat meningkatkan produksi ternak dan sekresi air susu baik pada manusia maupun hewan. Diketahui bahwa tanaman katuk memiliki bagian lain yang bisa dimanfaatkan dan diolah untuk dijadikan tepung pelet katuk, yaitu batang lunak. Bagian batang lunak secara proporsional dapat sebagai bahan baku pengganti daun dalam proses produksi pelet feed additive untuk ternak. Penelitian ini bertujuan untuk mengetahui pemanfaatan batang lunak sebagai bahan baku pellet katuk depolarisasi dan palatabilitas katuk terhadap domba dan sapi potong. Penelitian menggunakan 8 ekor domba dan 12 ekor sapi potong untuk uji palatabilitas dan menggunakan 18 kg tanaman katuk. Hasil penelitian menunjukkan bahwa panjang batang lunak yang dipanen pada periode pertama tidak berbeda nyata (p>0,05) dengan panen periode kedua, namun untuk bobot daun dan bobot panjang batang lunak berbeda nyata dengan panen periode kedua (p<0,05). Panen periode pertama menghasilkan bobot daun dan batang lunak lebih tinggi dari panen periode kedua. Hasil uji palatabilitas terhadap domba menunjukan baik pelet D maupun pelet DBL sama-sama disukai oleh domba. Uji palatabilitas pelet dan bubuk katuk terhadap sapi melihatkan perbedaan yang nyata (p<0,05), sapi lebih menyukai katuk dalam bentuk pelet dibanding bubuk., Katuk plant leaves (Sauropus androgynus (L.) Merr) as a drug or feed additive (feed additive) can increase livestock production and milk secretion in both humans and animals. It is known that the katuk plant has other parts that can be utilized and processed to make katuk pellet flour, namely the soft stem. The soft stem portion can be proportionately as raw material for leaf replacement in the process of producing feed additive pellets for livestock.This research aims toknowing the utilization of soft stems as raw material for depolarizing katuk pellets and the palatability of katuk for sheep and beef cattle.The study used 8 sheep, 12 cows for palatability testing and used 18 kg of katuk plants.The results showed that the length of soft stems harvested in the first period was not significantly different (p>0,05) from the second period, but leaf weight and soft stem length were significantly different from those of the second period (p<0,05). The first harvest period resulted in higher leaf and soft stem weights than the second period harvest. The results of the palatability test on sheep showed that both D pellets and DBL pellets were equally favored by sheep. The palatability test of pellets and katuk powder on cattle showed a significant difference (p<0,05), cattle preferred katuk in the form of pellets compared to powder.

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.
