Judul: Faktor-Faktor Yang Mempengaruhi Kurang Energi Protein (KEP) Anak Umur 6 -18 Bulan Pada Keluarga Tidak Miskin Di Kabupaten Lima Puluh Kota, Propinsi Sumatera Barat
Abstrak: Tujuan penelitian adalah mengidentifikasi faktor-faktor yang menyebabkan kekurangan energi protein anak 6 - 18 bulan pada keluarga tidak miskin. Disain penelitian adalah Cross Sectional dengan pemilihan iokasi dilakukan secara sengaja (purposive) di Kabupaten Lima Puluh Kota. Lama penelitian 2 bulan yaitu bulan Mei sampai Juni 2001. Populasi adalah keluarga tidak miskin yang tinggal di lingkungan tidak kumuh dan mempunyai anak berumur 6 - 18 bulan yang menderita KEP. Contoh dipilih secara sengaja sebanyak 60 orang dengan perbandingan laki-Iaki dan perempuan seimbang dan mempunyai kriteria : BB/U dengan nilai z-skor di bawah -2,0 sd, lahir cukup bulan, tidak lahir dengan berat badan rendah, tidak menderita penyakit bawaan (jantung, paru-paru) dan merupakan anak kandung dan orang tua yang menjadi responden.

Judul: Beberapa Faktor yang Berhubungan Dengan Kurang Kalori Protein Pada Anak Balita : Studi Kasus Di Klinik Pusat Penelitian Dan Pengembangan Gizi, Kotamadya Bogor
Abstrak: Tujuan penelitian ini adalah mempelajari beberapa faktor yang berhubungan dengan tingkat Kurang Kalori Protein pada anak Balita. Penelitian dilaksanakan di tempat tinggal responden yang tersebar di Kotamadya Bogor dan Kabupaten Bogor. Pengambilan contoh dilakukan dengan cara Acak Distra tifikasi. Data yang dikumpulkan adalah data primer den data sekunder. Data primer meliputi data sosial, ekonomi, kesehatan, pengetahuan gizi ibu dan konsumsi makanan anak Balita penderita KKP, Data sekunder meliputi alamat dan penilaian tingkat KKP. Analisis statistik yang digunakan untuk menguji hubungan adalah uji X², dan untuk mengetahui keeratan hubungan digunakan ukuran C menurut Cramer. Hasil penelitian menunjukkan hubungan yang sangat nyata antara jarak kelahiran, umur penyapihan dan pengetahuan gizi ibu terhadap masing-masing kelompok KKP pada anak Balita. Sedangkan jumlah anak dan pengeluaran pangan keluarga tidak menunjukkan hubungan yang nyata secara statistik. Konsumsi energi den zat gizi anak Balita kelompok I lebih tinggi daripada kelompok II, meskipun masih di bawah 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
