Judul: The Effect of Different Flushing Management on Local Ewes Production Perfromance During Pregnancy
Abstrak: Penelitian ini bertujuan menganalisis pengaruh manajemen flushing yang berbeda terhadap performa produksi induk domba lokal selama bunting. Penelitian ini menggunakan 16 domba betina laktasi kedua dengan rata-rata bobotnya 30,06 ± 6,20 kg dan ditempatkan di kandang individu. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 4 kelompok. Perlakuan terdiri atas P1 = tanpa flushing, P2 = flushing sebelum dan setelah dikawinkan, P3= flushing sebelum dan setelah dikawinkan, serta di tengah kebuntingan, P4 = flushing sebelum dan setelah dikawinkan, ditengah dan diakhir kebuntingan. Rasio hijauan : konsentrat dalam ransum adalah 30 : 70 % berdasarkan bahan kering. Peubah yang diamati meliputi konsumsi nutrien, body condition score (BCS), pertambahan bobot badan harian (PBBH), efisiensi pemanfaatan pakan, dan income over feed cost (IOFC). Data dianalisis dengan ANOVA dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0,05) terhadap konsumsi bahan kering, konsumsi protein kasar, konsumsi serat kasar, konsumsi Beta-N, BCS, PBBH, efisiensi pemanfaatan pakan, dan nilai IOFC. Manajemen flushing berpengaruh nyata (P<0,05) terhadap konsumsi lemak kasar, konsumsi total digestible nutrient (TDN), dan perubahan nilai BCS sebelum dan setelah flushing. Disimpulkan bahwa manajemen flushing yang berbeda dengan penambahan minyak ikan lemuru sebelum dan setelah kawin, ditengah, dan diakhir kebuntingan mampu meningkatkan dan memperbaiki performa produksi induk domba lokal serta menghasilkan keuntungan yang paling tinggi., The aim of this research was to analyze the effect of different flushing management on local ewes production perfromance during pregnancy. This research used 16 second lactating local ewes, average weight was 30,06 ± 6,20 kg and placed in individual cages. This research used a Randomized Block Design (RBD) with 4 treatments and 4 replications. P1 = without flushing, P2 = flushing during before and after matting, P3 = flushing during before and after matting, and in the middle of pregnancy, P4 = flushing during before and after matting, in the middle and end of pregnancy. Ratio forages and concentrate in the ration were, 30:70 % dry matter basis. The parameter observed were nutient consumption, body condition score (BCS), body weight gain (BWG), feed utilization efficiency, and income over feed cost (IOFC). The data were analyzed using ANOVA and Duncan test. The results showed that the treatment did not significant effect (P>0,05) on consumption of dry matter, consumption of crude protein, consumption of crude fiber, consumption of Beta-N, BCS, BWG, feed utilization efficiency, and IOFC. Flushing management had significant effect (P<0,05) on consumption of crude fat, consumtion of total digestible nutrient (TDN), and difference of BCS before and after flushing. It was concluded that different flushing management with the addition of lemuru fish oil before and after matting, in the middle and end of pregnancy increased and improved production perfromance of local ewes, and produced the highest profit.

Judul: The Effect of Different Flushing Feed Management on Local Ewes Hematology at the End of Pregnancy
Abstrak: Penelitian ini bertujuan menganalisis efek dari manajemen pakan flushing yang berbeda pada hematologi domba lokal di akhir kebuntingan. Ternak yang digunakan sebanyak 12 ekor domba lokal betina laktasi kedua dengan berat rata- rata 29,75 ± 6,02 kg dan ditempatkan di kandang individu. Penelitian menggunakan Rancangan Acak Kelompok 4 x 3 yang dikelompokkan berdasarkan bobot badan ternak. Perlakuan terdiri atas P1 = Tanpa flushing, P2 = Flushing sebelum dan setelah kawin, P3 = Flushing sebelum dan setelah kawin serta tengah kebuntingan, P4 = Flushing sebelum dan setelah kawin, tengah serta akhir kebuntingan. Perbandingan hijauan dan konsentrat dalam ransum adalah 30:70 berdasarkan bahan kering. Parameter yang diamati adalah hematokrit, kadar hemoglobin, Butir Darah Merah (BDM), Butir Darah Putih (BDP), dan persentase diferensiasi leukosit yang terdiri dari limfosit, monosit, neutrofil, basofil, dan eosinofil. Analisis data menggunakan uji ANOVA dan Duncan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0,05) terhadap hematokrit, kadar hemoglobin, Butir Darah Merah (BDM), dan diferensiasi leukosit. Manajemen flushing berpengaruh signifikan (P<0,05) terhadap Butir Darah Putih (BDP). Dapat disimpulkan flushing sebelum dan setelah kawin, tengah dan akhir kebuntingan meningkatkan nilai hematologi ternak dibandingkan dengan perlakuan tanpa flushing, flushing sebelum dan sesudah kawin, flushing sebelum dan sesudah kawin serta tengah kebuntingan., This study was aimed to analyze the effects of different flushing feed management on the hematology of local sheep at the end of pregnancy. This research used 12 second lactating local ewes, average weight was 29,75 ± 6,20 kg and placed in individual cages. This research used a randomized block design (RBD) with 4x3 that are grouped based on body weight of ewes. The treatments consisted of P1 = without flushing, P2 = flushing during before and after matting, P3 = flushing during before and after matting, and in the middle of pregnancy, P4 = flushing during before and after matting, in the middle and end of pregnancy. Ratio forages and concentrate in the ration were, 30:70 % dry matter basis. The parameter observed were hematocrit, hemoglobin level, Red Blood Cell (RBC), White Blood Cell (WBC), and leukocyte diferentation consisting of lymphocytes, monocytes, neutrophils, basophils, and eosinophils. The data were analyzed using ANOVA and Duncan test. The results showed that the treatment did not significant effect (P>0,05) on hematocrit, level hemoglobin, Red Blood Cell, and leukocyte diferentation. Flushing management had significant effect (P<0,05) on White Blood Cell (WBC). This study concluded that treatment with flushing before and after mating, midle of pregnancy and end of pregnancy increases hematological value of cattle compared to treatments without flushing, flushing before and after mating, and flushing before and after mating, midle of pregnancy.

Judul: Analisis dan Implementasi Certificate Authorities (CA) pada Public Switched Telephone Network (PSTN)
Abstrak: Secure Telephone Protocol has ability to authenticate involved party and keep the secrecy of the message sent over the protocol. The secrecy of the message archieved by using symmetric key cryptographic scheme, and authentication archieved using public key cryptographic scheme. One of several party involved in the protocol and hold an important function called Certificate Authorities or CA. CA responsible for generating public key pair for other party involved in the protocol. When CA generates public key pair, several primitive cryptographic scheme used for guarantee the security of the key. Two of them are hash function SHA-1 and El-Gamal public key scheme embedded in Digital Signature Algorithm scheme. The prototype implementing the scheme above developed using Java programming language with JCE addition from Bauncy Castle. The analysis towards implemented prototype indicates that the prototype still has some flaws to be implemented in real world.
