Abstrak: Ex situ conservation is a means to save wildlife animal include lesser bird of paradise. Taman Mini Indonesia Indah (TMII) Bird Park and Mega Bird And Orchid Farm (MBOF) were two institutions that support ex-situ conservation program with different purposes. TMII Bird Park has non-commercial purpose breeding, while MBOF has commercial purpose in captivity breeding. The objectives of this research was to describe the management of captive breeding of lesser bird of paradise with the influencing factor for captive breedig success and the daily behavior of lesser bird of paradise in the cage. This research was conducted from March until April 2015. Focal animal sampling and one zero sampling method were employed to observe daily behaviour. The results showed that there were not differences in management between the two locations, and did not success for breeding. The behaviors had been identified were: resting, ingestive, locomotion, and maintenance behavior. The disturbances caused by visitors and other animals.

Judul: Determinant Factors of Successful Ex Situ Conservation of Lesser Bird of Paradise (Paradisaea minor Shaw, 1809).
Abstrak: Lesser bird of paradise (Paradisaea minor Shaw, 1809) is an endemic bird species in Papua island. Recently its population has been decreasing year to year, due to illegal hunting, illegal trading and habitat destruction. These cause a decrease in the quality and quantity of their habitat especially for feed, shelter, and cover. In order to increase its population in natural habitat needs an ex situ conservation effort such as conservation institution and captive breeding. Currently, ex situ conservation efforts of this bird are lacked and very low in the successful of breeding. The aims of this research were to identify and analyze the component that determine successful of lesser bird of paradise ex situ conservation, to determine a model of successful lesser bird of paradise ex situ conservation and to formulate the typology of succesful lesser bird of paradise ex situ conservation. The study was conducted from March until May 2016 in the TMII Bird Park , Mega Bird and Orchid Farm (MBOF), Ragunan Zoo, Bandung Zoo, and Al Wabra Wildlife Preservation (AWWP) in Qatar. The Data in this research include internal and external biological aspect of species, captive breeding technique, and social aspect. The qualitative data was changed into quantitative data with scoring of assessment. The variables was analyzed by Principle Component Analysis (PCA). The result of the research showed that the type of cage in TMII Bird Park, MBOF, Ragunan Zoo, Bandung Zoo was display cage. The temperature average cage in TMII Bird Park and Ragunan Zoo was 29⁰C and humdity was 86%. The temperature average in MBOF was 25⁰C and humidity 87.5 % and the temperature average in Bandung Zoo was 23.5⁰C and humidity 90.5 %. Type of feeds were divided into main feed and extra feed which were given everyday. The analysis of nutrient indicated that the protein of the feed consumption is about 6.9% with the energy is about 2578.3 ccal. The statistical analysis showed that there are five determinant factors of successful ex situ conservation of lesser bird of paradise. First components were age, feed and the keeper ability, second component was nest, third components were cage size and the availability of specialist, and fourth components were cage facilities and adaptability of the bird, and fifth components were disturbance and construction of the cage. These variables in determinant factors are used as basic data to formulate the model and typology. There are three typologies of succesful ex situ conservation which are based on internal aspects of the lesser bird of the paradise, captive breeding technique and the social aspect.

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
