Judul: Penilaian Prestasi Kerja Dalam Upaya Meningkatkan Produktivitas Karyawan : Studi Kasus Di Pt. Dsn Surabaya
Abstrak: Kenyataan di lapangan menunjukkan bahwa pekerjaan memiliki perbedaan pada kebutuhan kategori tingkat kesulitan, tingkat keterampilan, dan pengalaman pekerjanya. Perbedaan inilah yang menuntut penilaian prestasi kerja yang mencerminkan azas keadilan. Karyawan dalam melakukan pekerjaan dituntut untuk mencapai prestasi yang tinggi. Namun demikian pihak manajemen PT. DSN dalam melakukan penilaian prestasi kerja dituntut untuk menyadari berbagai faktor yang mempengaruhi karyawan (berdasarkan hasil uji Z) dalam mencapai prestasi kerja tersebut. Adapun faktor-faktor yang secara nyata mempengaruhi prestasi kerja karyawan berdasarkan hasil analisis uji Z adalah: kondisi tempat kerja, kompensasi, motivasi, umur karyawan, pengalaman, disiplin faktor keluarga...dst

Judul: Hubungan antara penilaian prestasi kerja dan motivasi kerja karyawan bagian produksi PT Saung Mirwan
Abstrak: Pengembangan sumberdaya manusia Indonesia perlu dilakukan, karena ketertinggalan Indonesia dalam hal mutu sumberdaya manusia. Sumberdaya manusia juga merupakan faktor penentu seberapa jauh sumberdaya lain dapat dimanfaatkan secara efisien, sehingga produktivitas sumberdaya manusia perlu ditingkatkan. Untuk mencapai produktivitas kerja yang tinggi, dibutuhkan motivasi kerja. yang tinggi, sehingga kebijakan yang tepat untuk memotivasi kerja karyawan sangat diperlukan. Sistem penilaian prestasi kerja yang baik juga diperlukan, karena selain berfungsi untuk memotivasi kerja karyawan, juga sebagai dasar bagi perusahaan untuk perbaikan produktivitas dan prestasi kerja karyawan. PT Saung Mirwan yang berlokasi di Desa Sukamanah, Kampung Pasir Muncang, Kecamatan Megamendung Bogor merupakan salah satu perusahaan agribisnis yang sedang berkembang. Untuk mencapai keunggulan bersaing, manajemen PT Saung Mirwan berusaha meningkatkan profesionalisme dalam pengelolaan sumberdaya manusia perusahaan. Hal-hal yang perlu diperbaiki dalam pengelolaan karyawan adalah (1) sistem penilaian prestasi kerja yang belum optimal, dan (2) kebijakan perusahaan dalam memotivasi karyawan, karena adanya gejala ketidakpuasan karyawan terhadap kebijakan kompensasi. Oleh karena itu penelitian..dst

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
