Abstrak: The aims of this research were to evaluate body growth, body condition score (BCS), and milk production of Holstein-Friesian (HF) dairy cattle maintained under smallholder dairy farms KPSBU Lembang, Bandung. The research was conducted during July to August 2007. The number of dairy cattle used was calves for 49 hd, heifers for 25 hd and cows for 148hd consisting of lactating cows for 133 hd and dry cows for 15 hd

Judul: Status Kecernaan Pakan dan Produksi Susu Induk Sebagai Indikator Pertumbuhan Pedet pada Sapi Perah (Friesian Holstein) di KPBS Pangalengan
Abstrak: Status of feed digestibility, milk production, and growth in cow and calf are indicator of performance improvement milk production and cow population in the dairy farm area. Study about the relation between feed, digestibilility, and performance (milk production and growth of calf) in the dairy farm area have not much done. Pangalengan is a central of dairy farm that coordinate by KPBS. The purpose of this research is to know about status of feed digestibility, milk production, and growth of calf in public farm KPBS Pangalengan. Sixteen weaning cows were used for feed digestibility and milk production observation, also sixteen calfs were used for body weight observation. The observational data of the overall parameters was analyzed descriptively then statistically using analysis of variance (Anova) method. Status of feed digestibility and milk production of dairy cows in KPBS Pangalengan can be used as indicators of the growth calves. Percentage of feed digestibility which were dry matter 81.40%, crude protein 89.29%, crude fat 95.12%, crude fiber 63.54% and ash 77.34% show the feed digestibility was good. Milk production showed good quality in the first 8 weeks lactation which was 18.74 liter/cow/day. Growth of body weight in calf was 0.2 kg/calf/day. Based of these result, Dairy farm KPBS Pangalengan have good management for dairy cows that would keep the cows healthy and productive.

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.
