Judul: Model of dengue haemorrhagic fever controlling policy in Indramayu Regency
Abstrak: Dengue haemorrhagic fever (DHF) still becomes a problem in Indramayu regency. The occurance of DHF is linked to a number of factors, including the environment, population, health service, and vector of DHF (Aedes aegypti). The objective of this research is to establish a model of DHF controlling policy in Indramayu regency used quantitative and qualitative analysis, observational, cross sectional, Analytical Hierarchy Process, Interpretative Structural Modelling, and system approach. The location of this research is in six districts: Sindang, Indramayu, Jatibarang, Terisi, Sukagumiwang, and Tukdana. Respondents were 721 persons, consisted of 671 head of families (with random sampling), and 35 officials from government institution and 15 as experts (with purposive sampling). The results of study show that the occurance of DHF is statistically have significant relationship with (1) the health condition of household, (2) the household’s water income, (3) the household’s garbage handling, (4) the respondent’s knowledge of DHF, (5) the healthy behavior of the member of the family, (6) the household’s money income/expenditure per capita, (7) the respondent’s formal education, (8) the schedule to cleaning out the water container, and (9) the rainfall index. The main strategy to control the occurance of DHF, based on Analytical Hierarchy Process, such as the increase of healthy living environment. The key factors to control the occurance of DHF, based on prospective analysis of the Interpretative Structural Modelling outputs, id est: interprogrammer and interinstitutional cooperation at all of government administration level and supporting of environment health education. The model simulation result can give a description of the real system behavior. Of the three formulated scenarios (optimistic, moderate, and pesimistic), application of optimistic scenario is assumed as the most effective. The DHF controlling policy that need to be implementated is focused to the four factors, id est: (1) the health environment: household garbage handling, waste water, water supplies, space and building sanitation, and mosquito repellent house plant, (2) the demography: population growth; and the community knowledge, attitude, and practice; (3) the health service: cure and health education program; and (4) the vector of DHF: management of the water storage containers, Aedes aegypti eggs, larvaes, pupa, and preventive measure of the Aedes aegypti mosquitos bite. In order to implement the DHF controlling policy effectively, Indramayu government need to increase (1) the good management of the interprogrammer and interinstitutional cooperation and good management of the controlling DHF team sistematically from the regency to the district administration, (2) the supporting of technologies, funds, facilities, and standard operating procedure of health education, and (3) the service quality of the Public Health Centre.

Judul: Identify Potential of Dengue Hermologic Fever (DHF) Vulnerabilities as Climate Change Impacts with The Logit Model (Study in Jakarta Province)
Abstrak: Global warming as the trigger of climate change is a very important issue in many countries, the data showed global average temperature increase by 0.74oC during the 20th century. Rising sea levels from the 19th century until the 20th The results of ordinal logistic regression analysis, the models with socio-demographic and climatic variables as predictor is a good model with about 80% accuracy rate, and pass the test individually and overall. So by using the model to calculate the degree of vulnerability of each district then the resulting degree of vulnerability to be spatial in the map. century amounted to 0,17 m, this is consistent with extensive snow cover decreased by 7% since 1900. The fact of climate change and Indonesia's geographical position is on the growth of endemic mosquito Aedes aegypti as a dengue vector, Climate change will accelerate the spread of dengue virus due to changing rainfall patterns, high frequency and irregular rainfall and warmer temperatures will increase the number of mosquito Aedes aegypti. The Purpose of this research is determining the association between risk factors of DHF with Climate (Temperature and Rainfall), determining the factors that influence susceptibility DHF region of Jakarta, and social demography in Jakarta area and the finally purpose is determining the potential vulnerability of dengue in the Jakarta province as well as display them spatially in a map of dengue due to climate change vulnerability.

Judul: Karakteristik Piezoelektrik Film LaxSr₁-xTiO3 di atas Substrat TCO
Abstrak: Studi material perovskite SrTiO3 sudah banyak dilakukan dan menunjukkan sifat feroelektrik, piezoelektrik, kuantum paraelektrik dan superkonduktor yang baik. Dengan penambahan dopant La2O3 diduga menambah performa sifat piezo dan karakteristik lainnya. Karakteristik film LaxSr₁-xTiO3 (LST) dengan variasi x= 0, 0.02, 0.04, 0.06 terbentuk pada suhu annealing 550 oC di atas substrat TCO melalui metode (Chemical Solution Deposition) CSD dan spin coating dengan 700 rpm pada kondisi suhu ruang dan tekanan atmosfer standar. Hasil menunjukkan, semakin banyak pendadah La maka nilai ketebalan film, ukuran rerata kristalit, parameter kisi, transmitansi, nilai konduktivitas (maksimum 589.7 S/cm pada sampel x=0.04 di frekuensi 10 Hz), nilai konstanta tegangan (c) dan muatan (d) piezo semakin meningkat. Dinamika bentuk grafik nilai tegangan (V) dan konstanta regangan mekanik (s) nampak mirip. Nilai V mencapai 0.127 V untuk x=0.06 (beban 50 g). Nilai maksimum c, d, s masing-masing mencapai 20.07 Vm/N, 1.14x10-8 C/N, 13642.71. Nilai band gap untuk x=0, 0.02, 0.04, 0.06 masing-masing 3.21 eV, 3.1 eV, 2.6 eV, 2.4 eV. La2O3 menambah performa sifat piezo, sehingga LST berpotensi sebagai sensor tekanan.
