Judul: Evaluasi Penerapan Good Farming Practice pada Peternakan Rakyat Domba di Desa Batur Kabupaten Banjarnegara
Abstrak: Tujuan dari penelitian ini adalah untuk mengevaluasi peternakan domba melalui analisis penerapan Good Farming Practice pada pemeliharaan domba batur oleh peternak rakyat di Desa Batur Kabupaten Banjarnegara. Peubah yang diamati dalam penelitian ini meliputi karakteristik peternak dan aspek-aspek GFP. Aspek GFP yang diamati terdiri dari aspek kandang dan peralatan, aspek bibit dan reproduksi, aspek pakan dan air minum, aspek pengelolaan, serta aspek kesehatan ternak. Penelitian ini dilaksanakan pada bulan Juli-Oktober 2016 menggunakan teknik snowball sampling sehingga mendapatkan sampel sebanyak 25 responden. Analisis deskriptif digunakan untuk menggambarkan kondisi umum wilayah, karakteristik peternak, dan perolehan data evaluasi GFP. Berdasarkan penilaian data GFP, nilai rata-rata GFP di Batur adalah 1.61, tergolong dalam kategori kurang baik. Implementasi aspek GFP yang dilakukan oleh peternak domba di desa Batur dari yang tertinggi ke yang terendah adalah aspek kandang dan peralatan (2.13), aspek kesehatan (1.96), aspek bibit dan reproduksi (1.77), aspek pengelolaan (1.46), serta aspek pakan dan air minum (0.61). Peternak batur perlu melakukan perbaikan pada seluruh aspek GFP dalam pemeliharaan domba batur, terutama pada aspek pakan dan air minum.

Judul: Evaluasi Penerapan Good Farming Practice pada Peternakan Domba PT Tawakkal Ternak Indonesia
Abstrak: Penelitian ini bertujuan untuk mengevaluasi Good Farming Practice (GFP) Penggemukan Domba di PT Tawakkal Ternak Indonesia, Caringin, Bogor, Jawa Barat. Jenis domba yang digemukkan di peternakan ini yaitu domba ekor tipis dan domba ekor gemuk. Aspek yang diamati dalam GFP penggemukan ini yaitu aspek sarana, proses produksi, pelestarian lingkungan, dan pengawasan. Pengambilan data dilakukan dengan metode observasi dan wawancara kepada manager dan direktur perusahaan. Analisis data menggunakan metode analisis deskriptif dengan pembobotan yang didasarkan pada kepentingan aspek terhadap GFP. Nilai total performa GFP sebesar 81.90% yang menunjukkan bahwa penerapan GFP PT Tawakkal Ternak Indonesia sudah baik. Ditinjau dari aspek sarana dan proses produksi, PT Tawakkal Ternak Indonesia sudah menerapkan GFP dengan baik dengan nilai tertimbang masing-masing 82.13% dan 85.25%. Nilai aspek pelestarian lingkungan dan pengawasan tergolong cukup baik dengan nilai tertimbang masing-masing 75% dan 71.25%.

Judul: Algorithm construction of HLI hash function
Abstrak: Cryptography is a study of mathematical techniques related to aspects of information security regarding on confidentiality, data integrity, entity authentication, and data origin authentication. Data integrity is a service, which is associated with the conversion of data carried out by unauthorized parties. To maintain data integrity, one can use hash functions. An hash function is a computationally efficient function to map an arbitrary length bitstring to a fixed length bitstring called as hash value. The use of hash function in maintaining the information integrity and authentication is in digital signatures, virus protection, and software distribution. Illustration of the hash function in the integrity and authentication of information that is emailed as follow. The sender sends the information and hash value to the recipient. If the hash value of the information is equal to the hash value that is sent by the sender, then information has not been changed. Otherwise the information has been changed. An hash function has two properties, one way and collision resistance. An hash function is called one way if it is computationally infeasible to find any input such that when given any hash value . Meanwhile an hash function is called collision resistant if it is computationally infeasible to find any two inputs where such that . The purpose of this study is to construct a HLI hash function algorithm, to analyze the speed and security of the hash functions as a results of construction. Furthermore, it is to compare it with SWIFFT. Hash function is constructed based on the result of algebraic operations on modular polynomial ringwith . Modular polynomial ring noted as is a set of all polynomials of degree at most with coefficients in . can be represented as a set of integer vector of modulo in dimension . So, it is simple to implement in a computer. In vector operations, is lattice . Furthermore, alattice that is defined from certain polynomial ring is called ideal lattice. HLI hash function is consists of addition and multiplication algorithm in the ring. Addition algorithm consists of sumation operations of modulo and multiplication consists of multiplication operations of modulo . Generally, algorithm of HLI hash function consists of multiplication operations of modulo and addition operations of modulo . However, if the input is binary number then multiplication algorithm only consists of multiplication operation of modulo , so algorithm of HLI hash function consists of multiplication operations of modulo and addtion operations of modulo . An hash function is secured if it has two properties, i.e., one way and collision resistance. HLI hash function hash is one way, it is following the proof of Micciancio. It is has collision resistant because of polynomial is irreducible over and monic. Moreover, it is proved that for every unit vector , the vector is small vector. If the input of hash function is a binary number then HLI hash function only involves addition operations of modulo . So the time that used almost same with SWIFFT. The excellence of HLI hash function is the key size smaller than SWIFFT. This effect on
