Judul: Metabolism of Date Extract in Dengue Hemorrhagic Fever Patients: Hematological Studies.
Abstrak: Dengue Hemorrhagic Fever (DHF) is one of health problems in Indonesia. The purpose of this research was to look for an alternative medication for DHF. This research was conducted by giving date extract to 14 DHF patients. Dose of date extract used was 30 mL per day. As a control for comparison, this research used medical records data of 9 patients. All of the patients were men, with age ranging from 15 to 35 years old. The blood overview measured were platelet, hematocrit, hemoglobin, and leukocyte using automatic blood counters Technicon H-1. In this research, hospital treatments were still executed. The treatments included giving medicines and adding ringer lactate infuses. The result of this research showed that the daily platelet increase percentage of DHF patient by giving date extract was higher than that of control data. The mean of platelet increase percentage per day by giving date extract was 23,90%, while the mean of the control data was 8,09%. The overall ANOVA analysis of the patients blood overview showed that giving date extract to DHF patients was not statistically significant (p>0,005).

Judul: Hematologic Study of Metabolic Potention Red Guava (Psidium guajava L.) on Dengue Hemorhagic Fever (DHF) Patient.
Abstrak: Red guava juice had been given to 17 male and 10 female patients who were divided into treatment and control patients. Control patients were the patients who were not given red guava juice and treatment patients were the patients who were given red guava juice 200mL three times a day. Both were given therapy by the hospital. Male patients were divided into 8 control and 9 treatment patients, 10 women patients were divided into 5 control and 5 treatment patients whose age ranged between 15-30 years old and were diagnosed to be infected by DHF according to the World Health Organization (WHO) method. Blood analysis was done once every 12 hours by using flow cytometri. The result showed that the red guava juice giving to the DHF patients was not significantly different (p>0.05) to the blood values, but it affected to the percentage value of trombocyte and hematocryte. The red guava juice giving to the male and female patient was able to improve trombocyte decreasing to 31.28% and 23.6% respectively. It was also able to reduce the percentage of hematocryte until 1.51% for male and 10.94% for female.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
