Judul: Pengaruh Kepribadian Ibu dan Dukungan Sosial terhadap Sosialisasi Emosi Ibu Bekerja pada Keluarga Perdesaan
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh kepribadian ibu dan dukungan sosial terhadap sosialisasi emosi pada ibu bekerja di keluarga perdesaan. Penelitian ini dilaksanakan di Kecamatan Ciampea, Kabupaten Bogor. Penelitian ini menggunakan desain cross sectional study. Populasi dari penelitian ini adalah ibu bekerja dari keluarga perdesaan yang memiliki anak usia remaja dari empat sekolah menegah pertama terpilih. Contoh dari penelitian ini terdiri dari 80 ibu bekerja yang dipilih menggunakan metode purposive sampling. Hasil menunjukkan bahwa semakin tinggi nilai kepribadian extraversion dan openness ibu maka semakin tinggi pula sosialisasi emosi yang diberikan ibu kepada anak. Selain itu, kepribadian openness ibu secara konsisten juga berpengaruh terhadap sosialisasi emosi. Hasil penelitian menegaskan adanya peran kepribadian ibu terhadap sosialisasi emosi yang dilakukan ibu kepada anak remajanya. Penelitian ini tidak menemukan hubungan antara dukungan sosial dan sosialisasi emosi.

Judul: Analisis Kepribadian Ibu, Gaya Pengasuhan Ibu, dan Kemandirian Remaja pada Keluarga Perdesaan
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan karakteristik remaja dan keluarga, kepribadian, dan gaya pengasuhan ibu, serta kemandirian remaja di perdesaan. Desain penelitian ini ialah cross-sectional study. Contoh dalam penelitian ini adalah remaja dan ibu dari tiga SMP terpilih di Kecamatan Ciampea. Jumlah contoh dalam penelitian ini adalah 100 remaja dan ibu yang terpilih melalui cluster random sampling. Hasil penelitian menunjukkan kecenderungan tipe kepribadian yang paling banyak dimiliki ibu adalah conscientiousness yang merupakan tipe kepribadian yang teliti, tertib, rajin, tekun, efisien, perencana, dan berfikir sebelum bertindak. Gaya pengasuhan dimensi positif (kehangatan, keteraturan, dan dukungan kemandirian) memiliki capaian yang lebih tinggi dari dimensi negatif (penolakan, ketidakteraturan, dan paksaan). Hasil penelitian tidak menemukan adanya hubungan dan pengaruh kepribadian ibu terhadap kemandirian remaja. Namun, uji regresi menemukan pengaruh kepribadian ibu terhadap gaya pengasuhan ibu dan hanya besar keluarga terhadap kemandirian remaja perdesaan.

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
