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.

Abstrak: The aim of the study was to compare and analize the effect of complete feed with different combination I. zollingeriana leaves and Leucaena leucochepala leaves on rabbit performance. This research used a randomized block design, with five dietary treatments and four replications. The treatments were R0 (commercial pellet ration with 0% Leucaena leucochepala and 0% I. zollingeriana), R1 (complete pellet ration containing 30% Leucaena leucocephala and 0% I. zollingeriana, R2 (complete pellet ration containing 20% Leucaena leucocephala and 10% I. zollingeriana), R3 (complete pellet ration containing 10% Leucaena leucocephala and 20% I. zollingeriana), R4 (complete pellet ration containing 0% Leucaena leucocephala and 30% I. zollingeriana). Variables observed were feed intake, body weight gain, feed efficiency, fat content, carcass and non carcass weight, liver, heart, kidneys weights and Income Over Feed Cost. The data were analyzed with analysis of variance, and the differences among treatment were examined with Duncan Range Test. The results show that all complete pellet ration having the same effect in improving the performance of rabbits. Complete ration pellet with 30% Leucaena leucocephala and completed ration pellet with 30% I. zollingeriana had a tendency to derease the fat content compared with commercial pellet rations. It can be concluded that complete pellet ration containing I. zollingeriana and Leucaena leucochepala can be recommended as rabbit pellet.

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.
