Judul: Studi Preferensi Tempat Bertelur dan Perkembangbiakan Jentik Nyamuk Aedes aegypti Pada Air terpolusi.
Abstrak: Strategi pengendalian nyamuk Aedes aegypti yang efektif adalah dengan mengetahui tempat perindukannya. Selama ini diketahui bahwa nyamuk A. aegypti hanya mau berkembangbiak pada air yang bersih, namun demikian ingin diketahui pula apakah air terpolusi dapat menjadi tempat berkembangbiak bagi nyamuk A. aegypti. Tujuan penelitian ini adalah untuk mengetahui tempat perindukan dan sebaran nyamuk A. aegypti di lapangan, preferensi A. aegypti dalam memilih media bertelur, serta perkembangan jentik dan pupa A. aegypti pada berbagai kondisi air terpolusi di Iaboratorium. Hasil penelitian menunjukkan bahwa indeks wadah di desa Cikarawang rata-rata adalah 7.6%, indeks rumah rata-rata 13.4% dan indeks Breteau rata-rata 14.8. Peletakan telur paling tinggi pada media yang berisi polutan tanah dan campuran polutan feses ayam, tanah dan detergen, sedangkan peletakan telur terendah pada polutan kaporit dan media berisi air sumur. Faktor-faktor yang mempengaruhi peletakan telur antara lain adalah indera olfaktori dan kehadiran mikroorganisme. Perkembangan pradewasa A. aegypti yang cukup baik terdapat pada media berisi polutan feses ayam dan campuran polutan tanah, detergen, kaporit dan feses ayam. Perkembangan pradewasa tergantung pada ketersediaan makanan, bahan organik dan anorganik. Hasil penelitian ini menunjukkan bahwa air yang terpolusi dapat menjadi tempat perindukan dan berkembangbiaknya nyamuk A. aegypti.

Judul: Status Kerentaan Nyamuk Aedes Aegypti Dari Daerah Endemis Penyakit Demam Berdarah Kotamadya Bogor Terhadap Temefos Dan Malation
Abstrak: Penelitian ini bertujuan mengetahui status kerentanan isolat nyamuk Aedes aegypti dari 20 lokasi pada kondisi lingkungan permukiman padat yang teratur (LPPT), kondisi lingkungan permukiman elit (LPE) dan kondisi lingkungan permukiman perdagangan atau pertokoan (LPPP). Larva dari semua isolat tersebut diuji kerentanannya dengan 5 konsen- trasi temefos dan nyamuk dewasanya diuji waktu kerentanannya dengan malation 5% ( 5, 10, 15 dan 30 menit ). Hasil pengujian status kerentanan larva Aedes aegypti 4 kondisi lingkungan permukiman menunjukkan yang diuji pada LPPP dari 5 3 isolat (60%) yang menunjukkan isolat bahwa yang kecenderungan pada isolat-isolat diuji ada kearah terjadinya resistensi, pada LPTT ada 2 isolat (40%) dan pada LPE ada 1 isolat (20%). Akan tetapi dari nilai rata-rata KL 95 seluruh populasi Aedes aegypti kotamadya Bogor masih dapat dianggap rentan. Hasil pengujian malation menunjukkan bahwa isolat Ae. aegypti asal Bogor masih rentan terhadap residu malation 5% dengan waktu letal/WL 95 rata-rata selama 29 menit.

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
