Judul: Otomasi Interpolasi Hujan Wilayah dengan Metode Thiessen.
Abstrak: Water in rivers affects human life. If the amount of rainfall exceeds normal limits, disaster can harm the society in the area. In order to prevent that, the calculation of rainfall is needed. Rainfall can be calculated using Thiessen method. However, calculating rainfall manually takes a long time. Thus, the purpose of this research is to implement Thiessen method such that the calculation will be faster. Thiessen method accommodates weighting rainfall using the area of rainfall stations. User will input parameters needed by system built in this research. These parameters are rainfall per rain station and area of rain stations. The system calculates the average of rainfall using Thiessen method. This value will be shown to the user to be used as needed. This system has been able to show the results of average rainfall calculation

Judul: Rainfall estimation based on geostationary (MTSAT-1R) and microwave imager (TRMM) satellite: Case study DAS Citarum
Abstrak: This research used blended satellite which are geostationary satellite (MTSAT-1R) and TRMM Microwave Imager (TMI). The analyze is based on the MTSAT-1R canal 1R1 with spatial resolution (0.05o x 0.05o) for brightness temperature and TMI with hourly temporal resolution. The research focussed which covered 462 pixels for Citarum Water Catchment Area. TMI is good enough to estimate the precipitation because using microwave to estimating volume of cloud but for temporal scale is not good enough. Assumed wind movement, atmosphere stabilization, and topography are ignored. The relationship analysis between the brightness temperature from MTSAT-1R and the rainfall from TMI have been conducted in this research. There is a relation between brightness temperature and rainfall. Decreasing of brightness temperature is comparable by increasing of precipitation. In the modified exponential regression between two variable, the equation is formed Rainfall estimation = a.e(b/cloud brightness temperature) with determination coefficient 0,71. Then, this modification is used to estimate the precipitation. The result showed that there is an overestimate between estimation data and field measurement data. Increasing quality of data followed by the higher time dimension data (daily, 5 days, 10 days). The ratio test produce calibration factor 0.5 that can reduce overestimate data. This methods are having advantages in spatial and temporal scales as geostationary. In order to increase the accuracy, the validation of data needs to be done by completing the TMI with other parameter and sources and also taking the topography of area into consideration.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
