Judul: Studi Perbandingan Keadaan Gizi, Konsumsi Pangan Dan Gizi Ibu Rumah tangga Di Desa Cangkuang (UPGK) Dan Karangsari (NON UPGK) Kecamatan Leles, kabupaten Garut, Propinsi Jawa barat
Abstrak: Dari hasil pengujian secara statistik ternyata memperlihat- kan bahwa keadaan gizi bayi dan anak balita di desa Cangkuang dan Karangsari tidak berbeda, demikian pula dalam hal konsumsi energi dan protein tidak berbeda, sedangkan keadaan pengetahuan gizi ibu rumah tangga di desa Cangkuang dan di desa Karangsari berbeda, dimana keadaan pengetahuan gizi ibu rumah tangga di desa Cangkuang lebih baik daripada di desa Karangsari. Baik di desa Cangkuang maupun di desa Karangsari belum dapat ditunjukkan adanya hubungan antara faktor-faktor konsumsi energi, protein dari bayi dan anak balita, dan pengetahuan gizi ibu rumah tangga dengan keadaan gizi bayi dan anak balita. Konsumsi rata-rata energi dan protein dari bayi di kedua desa masih di bawah angka kecukupan, sedangkan konsumsi rata-rata vitamin A sudah di atas angka kecukupan. Baik di desa Cangkuang maupun di desa Karangsari, konsumsi rata-rata energi dan protein anak balita golongan umur 1-3 tahun dan 4-5 tahun sudah di atas angka kecukupan, kecuali konsumsi rata-rata vitamin A pada anak balita golongan umur 1-3 tahun di desa Karangsari masih di bawah angka kecukupan.

Judul: Studi perbandingan suapan pangan dan status gizi anak balita antara dua desa di daerah program sistem kewaspadaan pangan dan gizi (SKPG) kab. Lombok tengah, Prop. Nusa Tenggara Barat : Studi kasus pada desa darmaji, Kec. Kopang dan desa Kawo, Kec. Pujut
Abstrak: Penelitian ini bertujuan untuk membandingkan suapan pangan dan status gizi anak balita di desa yang dahulu pernah mengalami rawan pangan berat dan rawan pangan sedang. Responden dipilih sebanyak 30 keluarga dari masing- masing desa dimana setiap keluarga minimal mempunyai satu anak balita. Dari pemilihan tersebut, didapat 36 anak balita dari Desa Darmaji dan 31 anak balita dari Desa Kawo. Pengambilan responden secara Purposive Sampling. Pengumpulan data dilakukan dengan wawancara menggunakan daftar pertanyaan dan pengukuran antropometri terhadap berat dan tinggi badan anak balita. Data suapan pangan anak balita diperoleh melalui metode penimbangan langsung selama dua hari berturut-turut. Status gizi anak balita ditentukan berdasarkan berat badan menurut tinggi badan yang dibandingkan dengan standart Harvard. Hasil penelitian ini menunjukkan bahwa suapan energi dan protein anak balita di dua desa ini hampir sama walau- pun ke dua desa ini beberapa tahun yang lalu berbeda dalam hal kerawanan pangan. Suapan energi anak balita di dua desa berada di bawah angka kecukupan yang dianjurkan, sedangkan suapan proteinnya sudah melebihi angka kecukupan yang dianjurkan....

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
