Judul: The Performances of the Meal Worms (Tenebrio molitor) Kept with a Different Density
Abstrak: Ulat hongkong (Tenebrio molitor) merupakan komoditas ternak yang termasuk ke dalam ternak prospektif. Pemeliharaan ulat hongkong harus dilakukan dengan tepat sehingga menghasilkan produksi yang optimal. Kepadatan kotak kandang pemeliharaan merupakan faktor yang berpengaruh pada saat pemeliharaan dalam meningkatkan produksi ulat hongkong. Penelitian ini bertujuan menganalisis performa ulat hongkong yang dipelihara dengan tingkat kepadatan berbeda. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga ulangan untuk setiap perlakuan. Peubah yang diamati adalah panjang badan, lebar badan, bobot kitin, bobot individu, bobot hidup total, dan mortalitas. Hasil penelitian menunjukkan tingkat kepadatan berbeda nyata (P<0,05) terhadap performa ulat hongkong. Tingkat kepadatan sebanyak 500 gram pada kotak kandang pemeliharaan memberikan hasil yang paling baik, yaitu pada rataan panjang badan, rataan bobot hidup total, rataan mortalitas, dan rataan bobot kitin., Meal worms (Tenebrio molitor) are chategorized as prospective animals. The farming of the meal worms must be done correctly to achieve their optimal production. The density of the during farming box is a factor that influences the maintenance process in increasing meal worm production. This study aims to analyze the performance of meal worms raised at different density levels. The study used a completely randomized design (RAL) with four treatments and three replications for each treatment. The observed variables were body length, body width, chitin weight, individual weight, total live weight, and mortality. The results of the study showed significantly different density levels (P<0.05) on the performance of meal worms. A density level of 500 grams in the farming box yielded the best results, particularly in average body length, average total live weight, average mortality, and average chitin weight.

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.
