Abstrak: Hydrological drought is a condition of water below normal and also a propagation of meteorological drought. The objectives of this study are to determine the thresholds level, to analyse drought characteristics, and to analyse frequency of hydrological drought in Ciujung, Brantas, and Bengawan Solo River basins. In this study, the hydrological droughts were identified by threshold level method. The 80-percentile (Q80) from flow duration curve was used to determined the threshold (Q0). The study reveals that the threshold of Ciujung, Brantas, and Bengawan Solo River basins 17.6 m3s-1, 73.1 m3s-1, dan 46 m3s-1, respectively. Minimum duration (dmin) amounting to 10 days was the criterion of hydrological drought events. Maximum durations of each river basin amounting to 134 days, 150 days, and 167 days, respectively, and maximum deficit volumes amounting to 153.789 x 106 m3, 501.824 x 106 m3, 495.853 x 106 m3, respectively. Bengawan Solo has the highest frequency of number of droughts which have duration more above 100 days than another.

Judul: Analisis Frekuensi Aliran Tinggi pada Beberapa Daerah Aliran Sungai di Pulau Jawa
Abstrak: Information about highflow frequency and its magnitude is needed for sustainable watershed management. The objectives of this research were to determine highflow threshold and to analyse highflow frequency of Ciujung, Brantas and Bengawan Solo river basin. Long term daily streamflow data were analysed using annual maximum series (AMS) and partial duration series (PDS). Exceedence frequency 5% was chosen as highflow threshold. Based on the threshold, return period of highflow from PDS and AMS was compared. Analysis result showed highflow threshold values of Bengawan Solo, Brantas and Ciujung watershed were 1,304 m3/s, 668 m3/s and 298 m3/s respectively. Log Pearson Type III was used to estimate highflow values at greater return periods. The plotting position of AMS showed smaller discharge than PDS at the same return period. While data analysis showed AMS discharge in various return period tend to be greater than PDS

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.
