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.

Abstrak: This study aimed to examine the effect of different feeding systems on post-mining of sand land performance of young Peranakan Etawah goat and lactation productivity of Etawah ewe The study used 12 goats (12,592 ± 1,326 kg) within 3-6 months of age. There were two factor of treatment. Treatment one was differences of eating time (W1 = 08.00 a.m to 04.00 p.m and W2 = 02.00 p.m to 04.00 p.m). Treatment two was type of feed (P1 = 100 g/day concentrate and forage, P2 = forage). Protein content of concentrate was 19,32% and forage affered ad libitum. The data were analyzed descriptevely for dry matter intake, feed eficiency and Income Over Feed Cost (IOFC) but the method for daily Body Weight Gain (BWG) used in this study was 2x2 factorial completely randomized design. The results showed that BWG of goats was significantly different among treatment (P<0,01). There was interaction betwent W & P trial. Daily BWG was significantly higher in trial W1 and P1 as well as IOFC with average daily BWG is 74,41 ± 11,89 and IOFC is Rp. 249.666,67. Subsequent study on the lactation productivity Etawah ewe of different feeding systems. This study used 15 goats within 10 goats in lactation two and 5 goats in lactation three. Treatment was differences type of feed (P1 = forage, P2 = forage and food industry waste). The data feed consumption were analyzed descriptevely. Data production and milk quality were analyzed using t test. Dry matter of milk was very significant higher (P<0,01) in ration added food industry waste than ration without food industry waste adition, while protein content and fat in milk was significant (P<0,05).

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.
