Judul: Karakteristik curah hujan DKI Jakarta dengan metode Empirical Orthogonal Function (EOF)
Abstrak: Curah hujan di Indonesia dipengaruhi oleh monsun yang digerakan oleh adanya sel tekanan tinggi dan sel tekanan rendah di benua Asia dan Australia secara bergantian. Dalam bulan Desember hingga Februari (DJF) dibelahan bumi utara terjadi musim dingin akibatnya terdapat sel tekanan tinggi di Benua Asia, sedangkan dibelahan bumi selatan pada waktu ini terjadi musim panas, akibatnya sel tekanan rendah di benua Australia. Karena ada perbedaan tekanan udara di kedua benua tersebut maka pada periode DJF bertiup angin dari tekanan tinggi di Asia menuju ke tekanan rendah di Australia, angin ini disebut monsun barat (winter monsoon). Dalam bulan Juni hingga Agustus (JJA) terdapat sel tekanan rendah di Asia dan sel tekanan tinggi di Australia yang menggerakan monsun timur (suntnter monsoon).

Judul: Penggunaan Empirical Orthogonal Function (EOF) untuk Identifikasi Karakteristik Curah Hujan (Studi Kasus: DAS Ciujung-Cidurian)
Abstrak: Rainfall in Indonesia is highly varied in space and time. The purpose of this research was identify spatial and temporal rainfall pattern, examine impact of ENSO on rainfall variability, and obtain the location of stations which had great impact on rainfall variability. The method used Empirical Orthogonal Function (EOF) and Rotated Empirical Orthogonal Function (REOF). From EOF obtained annual and seasonal rainfall variance dominated by monsoon system. Type of mountain topography also contributed on rainfall variability. EOF seasonal temporal patterns related with ENSO. It was seen from high value of correlation between EOF coefficient and SOI. Correlation between EOF1 with MAM, JJA, and SON period respectively -0.467, 0.413, and 0.32. EOF2 correlated with DJF and SON period with correlation respectively -0.555 and -0.588. Rotated Empirical Orthogonal Function (REOF) was used to see the contribution of each observation station by rotating the EOF. Type of rotation is varimax rotation.The result of rotation showed factor1 was determined by two station, Ragas Hilir and Jongjing station whereas other factors were determined by one stasion only.

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.
