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

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.
