Groundwater quality in Ponjong Karst, Gunungkidul Regency, Special Region of Yogyakarta

The hydrogeological condition of a region is determined by the type of lithology, morphology, and subsurface conditions where the condition is very helpful in the study of groundwater exploration. Especially when we encounter interesting geological conditions when the groundwater exploration in the karst area in which volcanic rocks are resulting from the activities of the active volcano in the past. Groundwater exploration at Ponjong area and surrounding does have its special characteristics, because it has 2 different rock characteristics where the northern part of the research area in the form of a karst area (limestone of Wonosari Formation) while the southern part is an area of ancient volcanoes with dominant volcanic rocks from Wuni Formation, As for the research on the above and subsurface research area where the research is conducted based on surface geology mapping, geoelectric data collection, and groundwater sampling. Geological mapping includes geomorphological data, stratigraphy, and geological structure. The aquifer system of the research area can be divided into two systems, inter-grain aquifer systems, and fracture aquifer systems. Overall quality groundwater in the research area is quite good. Ponjong District there are mining activities that have resulted in changes in the land use system in the area. This can cause changes in the water surplus in the area due to the changing catchment area

Analisa Pembeayaan Kerjasama Pemerintah Dan Swasta Pada Proyek Sidoarjo Town Square

Sidoarjo Town Square merupakan sebuah pusat perbelanjaan yang dibangun atas kerjasama swasta dan pemerintah. swasta sebagai investor dan pemerintah sebagai pemilik lahan. Proyek ini direncanakan memiliki masa investasi 15 tahun dengan sistem kompensasi akhir, dimana bangunan akan menjadi milik pemerintah setelah masa investasi berakhir. Tujuan dari penelitian ini adalah untuk mengetahui keuntu-ngan antara swasta dan pemerintah selama masa investasi serta perbandingan tingkat keuntungan antara kedua pihak. Untuk mengetahui tingkat keuntungan tersebut dipergunakan perhitu-ngan analisa aliran kas dengan parameter analisa pembeayaan yaitu NPV dan PI. Kemudian dilanjutkan analisa sensitivitas dengan mengubah masa investasi.

Several Dominants Risk Factors Related to Obesity in Urban Childbearing Age Women in Indonesia

Background: The prevalence of women suffered from obesity is elevating, mostly in urban areas. Thiscould lead problems especially for chronic diseases. This study aimed to analyze several dominant riskfactors related to obesity in childbearing age women living in urban areas in Indonesia.Methods: This analysis used a part of Basic Health Research (Riskesdas) 2007 data. The samples werederived from 258366 households. Riskesdas data on socio-demographic and other factors was collectedby questionnaire. Nutritional status was measured using body mass index (BMI). Cox regression withconstant time analysis was used for the analysis.Results: This analysis noted that there are 14357 (18.8%) of women were obese and 62052 (81.2%)normal. Compared with the respective reference groups, women aged 25-49 had a 3.5-fold greater riskof becoming obese [adjusted relative risk (RRa) = 3.49; P = 0.000), and divorced or married had 2.5-foldhigher risk to be obese (RRa = 2.58; P= 0.000 and RRa = 2.62; P = 0.000, respectively). Furthermore,unemployed women had higher risk to be obese (RRa = 1.06; P = 0.000), and consuming excess proteinas well as often consume fatty foods made women had a higher risk of obesity (RRa = 1.09; P = 0.000 andRRa = 1.17; P = 0.000, respectively).Conclusion: Women aged 25-49, divorced or married, unemployed, consumed excess protein, and often consumefatty foods have a higher risk for becoming obese.

Pengukuran Dan Penghitungan Volume Phantom Dari Citra Computed Tomography (Ct) Scan

The research has been done to the measurement and calculation of phantom volume of computed tomography (CT) Scan image. The aim of the study is to calculate the phantom volume based on CT Scan image analysis and find out the relationship between phantom volume and the variation of phantom position towards central ray. The calculation was done by using trapezoid integration method. The study used 130 kV, 93 mAs tube current, and 8 mm slice thickness. The resulting image is converted from gray scale image into a binary image. Then the surface area of the phantom was calculated. After getting the phantom surface area so that the volume of the phantom can be calculated. The calculation result shows that the phantom volume based on CT Scan image with perpendicular phantom, 30 mm to-the-left movement, 50 mm to-the-right movement towards central ray is 11160708 mm3, 11148172 mm3, and 11149136 mm3. The phantom volume based on CT Scan image with the least error percentage when phantom position is perpendicular towards central ray is 3,63%. 30 mm to-the-left and 50 mm to-the-right movement of phantom shows greater error percentage compared with perpendicular phantom towards central ray. The error percentage is from 3,74 % and 3,73 %. Phantom volume calculation is more accurate if phantom is perpendicular towards central ray
