Judul: Evaluasi Efek Kombinasi Medetomidin- Acepromazin Sebagai Agen Anestesi General Pada Kucing Lokal Indonesia
Abstrak: Kucing lokal merupakan salah satu hewan kesayangan yang banyak dipelihara masyarakat Indonesia. Berbagai penyakit sering muncul pada pemeliharaan kucing lokal dan tidak jarang membutuhkan tindakan bedah. Pada kasus yang memerlukan tindakan pembedahan, anestesi mutlak diperlukan sebagai sediaan penghilang rasa sakit. Penelitian ini dilakukan untuk mengevaluasi efek kombinasi sediaan anestesi acepromazin dan medetomidin terhadap onset, durasi, dan kondisi fisologis pada kucing lokal. Dua puluh empat kucing lokal jantan, berumur sekitar 1,5 sampai dengan 2,5 tahun, dengan bobot badan berkisar antara 3 kg sampai dengan 5 kg dibagi menjadi empat perlakuan dan enam ulangan. Perlakuan tersebut ialah kucing percobaan yang tidak diberikan anestesi (kontrol), kucing percobaan yang disuntik acepromazin 0.75 mg/kg BB (perlakuan I), kucing percobaan yang disuntik medetomidin 0.05 mg/kg BB (perlakuan II), dan kucing percobaan yang disuntik acepromazin 0.75 mg/kg BB dan sesaat setelahnya disuntik dengan medetomidin 0.05 mg/kg BB (perlakuan III). Sediaan tersebut diberikan secara intramuskuler pada perlakuan I, II, dan III. Parameter yang diamati terdiri atas onset (rasa nyeri, tonus otot, sedasi, kesadaran, emetik, refleks pedal dan pupil), durasi (rasa nyeri, tonus otot, sedasi, kesadaran, refleks pedal, dan pupil), dan kondisi fisiologis (frekuensi napas, frekuensi jantung, dan suhu rektal). Hasil penelitian ini menunjukkan bahwa kucing percobaan yang disuntik kombinasi acepromazin-medetomidin memiliki onset yang lebih cepat dibandingkan medetomidin dan mempunyai durasi yang sama dengan sediaan tunggal (acepromazin dan medetomidin). Kombinasi medetomidin acepromazin dapat mengurangi penurunan frekuensi jantung yang disebabkan oleh medetomidin. Pemberian acepromazin dan medetomidin secara tunggal maupun dikombinasi secara signifikan menurunkan frekuensi pernapasan dan suhu retal. Kesimpulan yang diperoleh dalam penelitian ini ialah kombinasi acepromazin dan medetomidin efektif digunakan sebagai alternatif sediaan sedatif pada kucing lokal Indonesia.

Judul: Potensi Kombinasi Anastetikum Xylazin- Medetomidin Pada Kucing Lokal (Felis domestica).
Abstrak: Xylazine and medetomidine preparations most used as anesthetic. Both single dose xylazine and medetomidine has advantages and disadvantages in application, so some research was done to find out the effect combination xylazinemedetomidine. Twenty four adult cats with body weight between 3.5-5 kg in age of 2-3 years old are divided into four groups treatment and six repeatation. The groups are the ones not receive anesthesia treatment (controls), a group of xylazine at a dose 0.1 mg/kg weight (group I), a group of medetomidine at a dose 0.05 mg/kg weight (group II), and a group of xylazine 0.1 mg/kg weight combination with medetomidine 0.05 mg/kg weight (group III). The results shows cats injected with xylazine-medetomidine has a rapid onset compared to single dose of xylazine and medetomidine. The duration of preparations in a cats injected with combination of xylazine-medetomidine is longer than xylazine and medetomidine preparations. The respiration frequency of heart shows same decrease pattern and not significant. The group xylazine-medetomidine can keep cats body temperature stable during the process of anesthesia, Conclusion in this study is the combination of xylazine and medetomidine effectively used as an alternative anesthesia in local cats.

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
