Judul: Evaluasi Kesesuaian Lahan untuk Pendugaan Debit Mata Air Menggunakan Metode Inferensia Fuzzy Sugeno
Abstrak: Water is one of the human needs in addition to clothing, food, and housing. However, many springs are not properly maintained causing various diseases in humans. Another problem is the loss of spring water sources due to improper handling of human or natural disasters. Therefore a research is needed to help people identify the source of good quality water springs, in this case good quality of water springs discharge rate. The research aims to calculate the spring discharge based on the number of plants, groundwater level, and topography angle by using the Sugeno fuzzy inference method. To verify the analysis and its results, an application using the application software APMA-Fuzzy has been developed. The data used for this research were obtained from field survey data from Balumbangjaya and Situgede villages. Further, Sugeno fuzzy membership function analysis is done by using gathered field survey data, while the rules that apply uses the expertise of a water spring expert. The concept of the rule is that the greater the input value, the greater the value of its output. Advanced analysis is carried out to determine the accuracy and reliability of Sugeno fuzzy method used in the application. The results were that each data from the thirteen field survey data has an accuracy of more than 50%, while the average accuracy was 77.53%. Thus, applications developed in this research is feasible and the rules that are used are also proved to be correct

Judul: Aplikasi hidrograf satuan sesaat Geomorfologi/GIUH untuk memprediksi debit sungai: studi kasus DAS Cibojong
Abstrak: One application of the concept of geomorphological instantaneous unit hydrograph/GIUH is to predict the flow of river that have no discharge gauge stations in the field (Ungauged Basin). The study was conducted through analysis of watershed geomorphology characteristics of digital elevation model (DEM) data using the program from Environmental Systems Research Institute/ESRI (ArcView GIS Software Version 3.3). After getting the parameters characteristic watershed geomorphology and net rainfall based on watershed area and then simulated using the model of H2U (Hydrogramme Unitaire Universel) to obtain the discharge simulation. Field discharge measurement data obtained from the automatic water level recorder (AWLR) data and rainfall data obtained from the data Automatic Weather System/AWS, both types of data were analyzed by using the aid program CIMEL Elektronique’s Automatic Weather Stations Management (CimSta’s Software) and Microsoft Office 2007 software programs. To compare the quality of the simulation results from the discharge and discharge in the field measurement results are validated by the F test (Nash and Sutcliffe 1970). Discharge simulation obtained from the four episodes in watersheds selected Cibojong resemblance to discharge measurements in the field. Episode December 23th, 2006, February 3th, 2007 episode, July 16th, 2007 episode, and October 25th,2007 episode of each F test value respectively 0.67, 0.89, 0.77, and 0.66. The tests are conducted to predictable streamflow in Cibojong Watershed.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
