Abstrak: Premenstrual syndrome (PMS) is a disorder characterized by symptoms that are manifested during the late luteal phase of the menstrual cycle and end shortly after the onset of menstruation. This research aimed to know assotiation between food intakes and premenstrual syndrome of adolescent school girls at Bina Insani Senior High School Bogor . This study design was cross-sectional study. Sampling method was purposive sampling. The number of samples that used was 59 adolescent school girls at 1st and 2nd grade. The result was there was no related between food habits with premenstrual syndrome and there was a relation between intake of calcium and vitamin B on premenstrual syndrome (p<0.05). High intake of calcium and vitamin B, it might reduce premenstrual syndrome.

Judul: Hubungan Aktivitas Fisik dan Stres dengan Sindrom Pramenstruasi pada Remaja Putri di SMA Bina Insani Bogor
Abstrak: Premenstrual syndrome occurs in 75-80% of reproductive woman age in the world. The purpose of this study was to determine the relationship of physical activity and stress with the occurrence of premenstrual syndrome of adolescent girls in Bina Insani high school Bogor. The research used crosssectional study design. Subjects in this research were adolescent girls between 15-18 years old who are still in grade 10 and 11 as much as 59 people. The sampling method used was proportionale stratified random sampling. There was no relationship between physical activity and premenstrual syndrome complaints levels (r= 0.289, p>0.05) and many types of menstrual complaints (r= 0.252, p>0.05). There is relationship between stress and types of complaints levels (r= 0.437, p<0.05) and complaints of premenstrual syndrome (r= 0.426, p<0.05). This showed that as stress level increased, the level and type of menstrual complaints also increased.

Judul: Penerapan teknik watermarking untuk penandaan hak cipta pada peta vektor dengan format DXF
Abstrak: Drawing Interchange Format (DXF) is one of the general file in the field of the vector image commonly used for making maps. The DXF format is a tagged data representation of all the information contained in an AutoCAD drawing (DWG) file. Tagged data means that each data element in the watermark is preceded by an integer number called the group code. The study was carried out because there is still no tools of labeling the copyright on digital mapping using DXF file. This study aims to generate an application for copyright labeling on vector map with DXF format that can be applied to any types of spatial objects in the map. The technique used is changing the code inside the vector image. The insertion of the watermark is done by utilizing ENTITIES section by multiplying objects for sets of binary values. The results showed that the image after the watermarking insertion process is the same as the original vector image. Embedded watermark is resistant to rotation and scaling, however it has the possibility of one-third to be broken in the attack on specific object. This study has successfully implemented watermarking technique for copyright labeling on the vector map with DXF format.
