Judul: Penangkaran Cendrawasih Kuning Kecil (Paradisaea minor Shaw,1809) di Taman Burung, Taman Mini Indonesia Indah dan Mega Bird and Orchid Farm.
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: Faktor-Faktor Penentu Keberhasilan Konservasi Eksitu Cendrawasih Kecil (Paradisaea Minor Shaw, 1809).
Abstrak: Cendrawasih kecil (Paradisaea minor Shaw, 1809) merupakan spesies endemik papua. Populasi cendrawasih kecil saat ini telah mengalami penurunan yang disebabkan tingginya perburuan, perusakan habitat, penyempitan habitat dan konversi habitat yang menurunkan kuantitas dan kualitas habitat alaminya terutama komponen pakan, shelter, dan cover. Upaya meningkatkan populasinya antara lain dengan melakukan konservasi eksitu di lembaga-lembaga konservasi maupun, melalui kegiatan pemanfaatan dalam bentuk penangkaran. Upaya konservasi eksitu cendrawasih kecil saat ini masih sangat terbatas dengan tingkat keberhasilan yang rendah. Tujuan dari penelitian ini adalah untuk mengidentifikasi dan menganalisis komponen yang berpengaruh penting dan relevan sebagai penentu keberhasilan konservasi eksitu cendrawasih kecil, menentukan model keberhasilan konservasi eksitu cendrawasih kecil dan merumuskan tipologi yang tepat bagi keberhasilan konservasi eksitu cendrawasih kecil. Penelitian dilakukan pada bulan Maret-Mei 2016 di Taman Burung TMII, Mega Bird and Orchid Farm, Taman Margasatwa Ragunan, Kebun Binatang Bandung, dan Al Wabra Wildlife Preservation di Qatar. Data yang diambil meliputi aspek internal biologis satwa, teknik penangkaran, serta aspek sosial yang dikuantitatifkan, dan dianalisis menggunakan metode Analisis Komponen Utama (AKU). Hasil penelitian menunjukan bahwa jenis kandang yang terdapat di Taman Burung TMII, Mega Bird and Orchid Farm, Taman Margasatwa Ragunan, dan Kebun Binatang Bandung yaitu kandang display. Hasil pengukuran rata-rata suhu di dalam kandang display di Taman Burung TMII dan Taman Margasatwa Ragunan yaitu 29⁰C dengan kelembaban yaitu 86% sedangkan suhu di dalam kandang display MBOF yaitu 25⁰C dengan kelembaban 87,5% dan suhu di Kebun Binatang Bandung yaitu 23.5⁰C dengan kelembaban 90.5%. Pakan yang diberikan berupa pakan utama dan pakan tambahan, yang diberikan setiap hari dengan kandungan gizi dalam pakan yang diberikan pada cendrawasih kecil di eksitu yaitu untuk kandungan protein sekitar 6,9% dengan kandungan energi didalamnya sebesar 2578,3 kkal. Hasil uji statistik menggunakan analisis komponen utama menunjukkan bahwa terdapat lima komponen penentu keberhasilan konservasi eksitu cendrawasih kecil. Komponen utama yang pertama adalah umur, pakan dan kemampuan keeper. Komponen kedua adalah sarang, komponen ketiga ukuran kandang serta ketersediaan tenaga ahli, komponen keempat fasilitas kandang dan kemampuan adaptasi, serta komponen kelima gangguan dan konstruksi kandang. Komponen penentu keberhasilan digunakan untuk merumuskan model dan tipologi keberhasilan. Terdapat tiga tipologi keberhasilan konservasi eksitu yang disusun berdasarkan aspek biologis satwa, teknik penangkaran dan aspek sosial.

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
