Judul: Profil Darah Kambing Peranakan Etawah Laktasi yang Mendapat Ransum dengan Berbagai Level Indigofera sp. Berbentuk Pellet
Abstrak: This research was conducted to evaluate the effect of level Indigofera sp. in the pellet ration on blood profile and physiological status of lactating etawa crossbred goat. Nine lactating goats with average body weight of 32.4 kg, were randomly divided into 3 treatments. The Rl contained pellet ration without Indigofera sp., R2 was pellet contained 20% Indigofera sp. and R3 was pellet contained 40% Indigofera sp. Each group consisted of 3 lactating goats. Drinking water provided ad libitum, while forage was given in the morning and afternoon. Variables measured were feed intake, physiological status and blood profile. This research was designed as block randomized design and data was analysis using ANOVA. The result showed that there were no significant effect of 40% Indigofera in the ration to blood profile, physiological status and feed consumption. The highest blood glucose concentration was in goat received pellet containing 20% Indigofera sp. in the ration and the highest blood urea concentration was in goat received containing 40% Indigofera sp. in the ration.

Judul: Respon fisiologis kambing Peranakan Etawah betina dengan pemberian pakan silase dan hay dari sumber hijauan berbeda
Abstrak: Kondisi lingkungan seperti pakan dapat mempengaruhi respon fisiologis kambing. Tujuan penelitian mengkaji pengaruh pemberian pakan silase dan hay dari sumber hijauan berbeda terhadap respon fisiologis dan profil darah kambing Peranakan Etawah betina yang dipelihara secara intensif. Penelitian ini menggunakan 12 ekor kambing betina berumur 4 bulan. Perlakuan dibagi menjadi tiga kelompok jenis pakan yaitu R0 (70% konsentrat + 30% silase dan hay hasil samping tanaman jagung), R1 (70% konsentrat + 30% silase dan hay limbah sayuran pasar pilihan), dan R2 (70% konsentrat + 30% silase dan hay hasil samping tanaman sorgum). Parameter respon fisiologis yang diamati adalah respirasi, denyut jantung, suhu rektal, dan parameter profil darah (hemoglobin, hematokrit, eritrosit, leukosit dan diferensial leukosit). Rancangan percobaan respon fisiologi menggunakan Rancangan Acak Lengkap (RAL) pola faktorial (3x3) dengan faktor utama yaitu jenis pakan dan faktor kedua yaitu observasi waktu, sedangkan profil darah menggunakan RAL pola faktorial (3x2) dengan faktor utama yaitu jenis pakan dan faktor kedua yaitu masa pemeliharaan. Data dianalisis menggunakan ANOVA dan uji lanjut Tukey. Hasil penelitian menunjukkan perlakuan pakan serta interaksi antara jenis pakan dan waktu pengamatan tidak menunjukkan perbedaan nyata terhadap respon fisiologis, tetapi waktu pengamatan sangat berbeda nyata (P<0.01) terhadap respirasi dan suhu rektal. Hasil profil darah menunjukkan waktu pemeliharaan berbeda nyata (P<0.05) terhadap leukosit, berbeda sangat nyata (P<0.01) terhadap jumlah hemoglobin dan hematokrit, namun kedua perlakuan serta interaksinya tidak berbeda nyata terhadap diferensial leukosit. Disimpulkan bahwa pakan silase dan hay berbasis hijauan berbeda tidak menyebabkan cekaman fisiologis kambing.

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.
