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: Kajian Potensi Transmisi Penyakit Demam Berdarah Dengue Berdasarkan Curah Hujan dan Suhu di Jawa Tengah
Abstrak: Dengue hemorrhagic fever (DHF) is a viral disease which has spread throughout Indonesia over the past 25 years. Ae. aegypti is the main vector of the disease. In Indonesia, especially in Central Java, there has been an upward trend in the incidence of dengue hemorrhagic fever. Therefore some efforts to suppress an outbreak of this disease had been done by the government with focus against the vector. This research aims to determine and mapping the transmission potential (TP) of DHF in Central Java under 4 principal seasons: rainy (December- February), transition 1 (March – May), dry (June-August) and transition 2 (September – November) at 3 rainfall conditions ( below normal, normal and above normal years) using vectorial capacity (VC) method. The results show that the maximum average VC for under normal years occur on December-February, whereas for normal and above normal years its occurs on March-May. In every rainfall condition, the minimum VC occur on June-August when rainfall is minimum. Based on resulted map from this research, in coastal area of northern and southern site of Central Java which is lowland area, TP were higher than in central area which is highland. TP on city with high population such as Tegal, Semarang, and Surakarta were higher. Nevertheless, between VC and incidence rate (IR) were significant with coefficient correlation 0.057, caused by there weren’t interventions between 35 districts in Central Java to supress the number of DHF disease in case of sanitation, vector controls (fogging, aerial spraying, making abate), immunity of society, etc.

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
