Judul: Studi Kasus Ketonuria Berdasarkan Urinalisis Semikuantitatif Strip-Test Pada Sapi Perah Di Peternakan Kunak Bogor
Abstrak: Kesehatan hewan merupakan aspek penting dalam meningkatkan produksi susu sapi perah. Salah satu tantangannya adalah bagaimana petugas di lapangan dapat menerapkan pendiagnosaan secara praktis. Untuk itu dilakukan penelitian berbasis studi kasus menggunakan urinalisis semikuantitatif strip-test terhadap 30 sapi perah di Peternakan KUNAK Bogor. Hasil pengamatan menunjukkan 2/30 hewan mengalami ketonuria. Mengingat ketonuria erat kaitannya dengan penggunaan energi cadangan, dalam penelitian ini dilakukan pemeriksaan Body Condition Score (BCS) dan pengukuran frekuensi pernapasan dan nadi. Hasil pengamatan menunjukkan bahwa sapi perah ketonuria memiliki nilai BCS 1.5 (kurus) dan peningkatan frekuensi pernapasan dan frekuensi nadi. Peningkatan frekuensi pulsus dan nadi ini merupakan indikasi peningkatan metabolisme. Studi kasus ini memberikan perspektif baru bahwa sapi perah kurus dapat mengalami ketosis selain sapi perah gemuk. Dalam konteks ini urinalisis menggunakan striptest merupakan metode yang efektif untuk mendiagnosa status kesehatan hewan. Adapun hewan yang mengalami gangguan keseimbangan energi beru ketonuria perlu di antisipasi dengan perbaikan nutrisi.

Judul: Productivity, Body Condition Score And Glucose Semi Quantitative Urinalysis Study On Dairy Cow At Kunak Bogor Indonesia.
Abstrak: Penelitian ini bertujuan untuk mengetahui situasi yang berkenaan dengan produksi susu sapi yang belum mencukupi kebutuhan domestik dan cenderung mengalami penurunan produksi. Untuk itu studi tentang produktivitas, skor kondisi tubuh (BCS), dan analisis glukosa urin semi-kuantitatif dilakukan pada sapi-sapi perah di kawasan usaha peternakan KUNAK, Bogor Indonesia. Pengamatan dilakukan terhadap 30 ekor sapi perah yang meliputi sapi bunting (2 ekor), baru melahirkan (6 ekor), dan sapi tidak bunting (22 ekor). Berdasarkan hasil pengukuran BCS, tercatat bahwa sapi bunting berada pada nilai yang rendah (BCS =2,5, n=1) dibandingkan dengan nilai BCS standard (2.75-3.50). Sapi yang baru melahirkan berada pada nilai yang rendah (BCS= 2, n= 1; BCS = 2.2, n= 1, BCS=2.5, n= 4) dibandingkan dengan nilai BCS standar (3.00-3.25). Adapun nilai BCS sapi tidak bunting tergolong dalam kondisi normal. Reagen strip tes urinalisis semi kuantitatif dilakukan untuk memeriksa profil kelainan pada leukosit, nitrogen, urobilinogen, protein, pH, tekanan darah, keton, bilirubin, dan glukosa. Diketahui 1% glukosaria dari sampel urin dan diketahui sebagai kelainan yang sifatnya asimptomatik. Penelitian ini membuktikan bahwa semi kuantitatif urinalisis reagen strip tes dapat digunakan sebagai basis dalam manajemen harian pada peternakan sapi perah.

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
