Judul: Kualitas Spermatozoa Kelinci Peranakan New Zealand White yang Diberi Pelet Ransum Komplit Mengandung Daun Indigofera zollingeriana dan Leucaena leucocephala
Abstrak: The experiment was conducted to study the effect of feeding complete ration in pellet form containing Indigofera zollingeriana and lamtoro (Leucaena leucocephala) leaves on sperm quality of New Zealand White crossbred rabbits. The rabbits were grouped according into 5 treatments with 4 replications. The treatments were R0 (commercial fed), R1 (complete ration containing 30% lamtoro leaves), R2 (complete ration containing 20% lamtoro leaves and 10% Indigofera leaves), R3 (complete ration containing 10% lamtoro leaves and 20% Indigofera. leaves), R4 (complete ration containing 30% Indigofera leaves). All of rations were fed to tested rabbits for 60 days, with preliminary trial period for 14 days. Semen was collected and its quality according to treatment were analyzed macroscopically and microscopically. The data were analyzed with statistic of descriptive. The results showed that there were no significant effect among given ration on sperm motility, viability and abnormality percentage of the rabbits. The range of percentage sperm motility, viability and abnormalities were 0%-70%, 46.88%-94.33%, 2.87%-19.33%, respectively. It is concluded that all complete rations containing Indigofera zollingeriana and lamtoro leaves played positive role on spermatogenesis in rabbit.

Judul: Kecernaan Nutrien pada Kelinci Peranakan New Zealand White Jantan yang Diberi Pellet Ransum Komplit Mengandung Indigofera zollingeriana dan Leucaena leucocephala
Abstrak: This research aim were to evaluate and compare dry matter, organic matter, crude fiber, crude fat, and crude protein digestibilities of I. zollingeriana and Leucaena leucocephala as pellet complete ration in New Zealand White male rabbits. Twenty rabbits of 4 months of ages, (1807± 255,87gram/head) were randomly assigned to one of the four treatments, i.e: R0 (Comercial diet), R1 ( Ration containing 30% Leucaena leucocephala), R2 ( Ration containing 20% Leucaena leucocephala + 10% I. zollingeriana), R3 ( Ration containing 10% Leucaena leucocephala+ 20% I. zollingeriana), R4 ( Ration containing 30% I. zollingeriana). The diets and water were offered ad libitum to the rabbits. Data from Completely Randomized Block Design (CRBD) were analyzed for ANOVA and contras orthogonal test . The result showed that treatments did not significantly affect intake of organic matter and crude fiber, but significantly affected intake of crude protein and crude fat. The treatments did not significantly affect digestibility of dry matter, crude fiber, crude protein and organic matter digestibility, but significantly affected crude fat digestibility. Digestibility of crude fat was 90,97%, 81,85 %, 75,38%, 84,97 % and 79,02% respectively for R0, R1, R2, R3 and R4. It is concluded that the substitution of Leucaena leucocephala with I. zollingeriana in rabbit diets did not affect dry matter, organic matter, crude protein and crude fiber digestibility

Judul: Pengamanan Internet of Things (IoT) untuk Tanda Tangan Digital Menggunakan Algoritme Elgamal Signature Scheme
Abstrak: Internet of Things (IoT) memungkinkan suatu objek menghasilkan data dan bertukar data. Pengaplikasian IoT menggunakan mikrokontroler seperti Arduino masih belum terdapat keamanan data di dalamnya. Selain itu, Arduino memiliki kapabilitas komputasi terbatas. Oleh karena itu, perlu diterapkan kriptografi dengan algoritme yang memiliki komputasi rendah pada Arduino untuk menjaga keamanan data. Keamanan data terutama pada keaslian asal data, dengan melakukan tanda tangan digital. Penerapan tanda tangan digital dapat dilakukan salah satu contohnya dengan algoritme Elgamal signature scheme. Penerapan tanda tangan digital menggunakan algoritme Elgamal signature scheme berhasil diterapkan pada perangkat Arduino Uno untuk melakukan tanda tangan digital dan verifikasi. Kinerja algoritme Elgamal signature scheme dilihat dari analisis waktu eksekusi dan analisis keamanan algoritme. Waktu eksekusi proses tanda tangan digital membutuhkan waktu lebih lama dibandingkan dengan waktu eksekusi proses verifikasi. Algoritme Elgamal signature scheme membutuhkan waktu dua kali lebih lama karena banyaknya perhitungan sistematis pada perangkat Arduino Uno. Proses verifikasi terbukti gagal jika ada perubahan data dan pasangan tanda tangan digital.
