Judul: Keragaman curah hujan indonesia saat fenomena indian ocean dipole (iod) dan el nino southern-oscillation (enso)
Abstrak: Fenomena iod (indian ocean dipole) dan enso (el nino-southern oscillation) ditandai dengan adanya perbedaan suhu permukaan laut (spl) dan pergerakan angin zonal maupun meridional yang dapat mempengaruhi anomali curah hujan. Penelitian ini bertujuan untuk menganalisis keragaman curah hujan indonesia saat terjadi fenomena iod, enso, dan kombinasi keduanya serta menjelaskan proses interaksi lautan-atmosfer yang mempengaruhi fenomena tersebut. Data yang digunakan yaitu data bulanan dari noaa dan cru dengan periode waktu 52 tahun (januari 1960-desember 2011). Dengan menggunakan analisis komposit, diperoleh bahwa saat terjadi fenomena iod positif (negatif) dan el nino (la nina) secara bersamaan kondisi curah hujan mengalami penurunan (peningkatan) yang signifikan dibandingkan pada fenomena tunggal. Pada fenomena tersebut perairan indonesia mengalami pendinginan (penghangatan) secara menyeluruh sedangkan wilayah samudera hindia-pasifik mengalami penghangatan (pedinginan). Kondisi ini konsisten dengan tekanan permukaan laut (tpl) yang lebih tinggi di indonesia dibandingkan samudera hindia-pasifik dan angin bergerak dari wilayah indonesia menuju samudera hindia-pasifik, demikian pula sebaliknya. Anomali sirkulasi walker menunjukkan bahwa wilayah indonesia mengalami divergensi sedangkan wilayah samudera hindia-pasifik mengalami konvergensi. Kondisi sebaliknya terjadi pada saat fenomena iod negatif dan la nina.

Judul: The Influence of the ﻿Super Indian Ocean Dipole ﻿(IOD) on Indonesia's Rainfall Anomaly in 2019
Abstrak: Indian Ocean Dipole (IOD) merupakan fenomena interaksi lautan dan atmosfer yang terjadi di kawasan Samudera Hindia. IOD memiliki keterkaitan dengan variasi iklim Indonesia, terutama variabilitas curah hujan. IOD cenderung terjadi bersamaan dengan El-Nino Southern Oscilation (ENSO), Namun hasil penelitian lainnya menemukan bahwa IOD dapat terjadi tanpa diiringi oleh ENSO. Salah satu IOD yang tidak diiringi ENSO adalah IOD (+) 2019. IOD juga memiliki keterkaitan dengan zona konvergensi (ITCZ). Penelitian bertujuan untuk mempelajari kondisi curah hujan Indonesia saat terjadinya IOD (+) 2019 serta keterkaitannya dengan sirkulasi atmosfer dengan menganalisis data-data curah hujan dan atmosfer. Penelitian ini meliputi tahapan analisis klimatologis curah hujan Indonesia, penentuan indeks IOD, analisis korelasi indeks IOD dengan curah hujan Indonesia, analisis anomali curah hujan dan suhu permukaan laut Indonesia tahun 2019, serta analisis klimatologis dan anomali zona konvergensi wilayah Indonesia tahun 2019. Hasil penelitian menunjukan bahwa IOD (+) 2019 menyebabkan penurunan curah hujan Indonesia, terutama saat memasuki periode bulan kering (Juli-September). IOD (+) 2019 juga menyebabkan terjadinya kontraksi/penyusutan ITCZ, sehingga menyebabkan terjadi penurunan curah hujan, terutama di Indonesia bagian Barat., Indian Ocean Dipole (IOD) is a phenomenon of ocean and atmosphere interaction that occurs in the Indian Ocean region. IOD has a relationship with Indonesia's climate variations, especially rainfall variability. IOD tends to occur simultaneously with the El-Nino Southern Oscilation (ENSO), but other studies have found that IOD can occur without ENSO. One of the IODs that is not accompanied by ENSO is IOD (+) 2019. IOD also has a relationship with the convergence zone (ITCZ). This study aims to study the conditions of rainfall in Indonesia during the IOD (+) 2019 and its relationship to atmospheric circulation by analyzing rainfall and atmospheric data. This research includes the stages of climatological analysis of Indonesian rainfall, determination of the IOD index, correlation analysis of the IOD index with Indonesian rainfall, anomaly analysis of rainfall and sea surface temperature in Indonesia in 2019, as well as climatological analysis and anomaly of the convergence zone of the Indonesian region in 2019. The results show that IOD (+) 2019 causes a decrease in Indonesia's rainfall, especially when entering the dry month period (July-September). IOD (+) 2019 also caused a contraction/shrinkage of the ITCZ, causing a decrease in rainfall, especially in western Indonesia.

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.
