Judul: Pemetaan Indeks Kekeringan dan Pola Tanam Menggunakan Metode Palmer (Studi Kasus: Jawa Barat)
Abstrak: Drought is closely related to rainfall decrease could affect the decline in rice production in one of rice production centers: West Java. This research aims to determine the drought level, drought index distribution map, and cropping pattern in West Java. Monthly rainfall, monthly average temperature, soil type, and land use data is processed by Palmer method. The highest value index is 22 and the lowest is -34. Area with the highest drought level is Northern area of West Java, while the central and southern part of West Java area tends to be wet. Peak of the drought occurs in August and September. On the strong El Nino years, the rainfall value becomes lower followed by drought index value. In the non-irrigated land, cropping patterns that can be applied is paddy-paddy-crop with the beginning of the season in November, while for the irrigated land rice can be planted up to three times a year. In the non-irrigated land at the north area that tends to be dryer, cropping patterns that can be applied is paddy-crop-crop with the beginning of planting season in December, if conditions are adequate irrigation of rice can be planted two or three times a year.

Judul: Vulnerability Level Of Agricultural Drought To Rice  Plant Productivity In The Province Of East Java
Abstrak: Kekeringan merupakan kondisi kurangnya ketersediaan air pada suatu wilayah dalam jangka waktu yang panjang dan berpengaruh terhadap intensitas kebutuhan manusia. Kajian kekeringan ini digunakan untuk memantau tingkat kekeringan yang terjadi khususnya di Jawa Timur yang merupakan sentra pertanian serta membandingkan tingkat kekeringan pada fenomena tahun El Nino kuat, tahun El Nino lemah, dan tahun normal. Penelitian ini menggunakan indeks SPI untuk menghitung kekeringan meteorologi, VHI untuk kekeringan pertanian serta NDVI untuk kerentanan kekeringan menggunakan 3 tahun yang berbeda yaitu tahun 2015 sebagai tahun El Nino kuat, tahun 2017 sebagai tahun El Nino lemah, dan tahun 2017 sebagai tahun normal untuk pembanding. Kejadian El Nino menyebabkan kekeringan yang tinggi dan waktu lebih panjang dibandingkan pada tahun normal. Terdapat perbedaan waktu terjadi kekeringan meteorologi dengan kekeringan pertanian, hal ini disebabkan oleh adanya time lag (penundaan) antara curah hujan dengan munculnya gejala kekeringan pertanian. Time lag antara kekeringan pertanian dengan kekeringan meteorologi terjadi selama tiga bulan. Kerentanan kekeringan pada tahun El Nino memiliki kerentanan yang lebih tinggi dan stabil dibanding pada tahun normal, dimana kerentanan yang terlalu tinggi kurang cocok sebagai tempat budidaya tanaman yang rentan terhadap kekeringan, seperti padi. Produktivitas padi pada tahun 2019 merupakan produktivitas terendah dibandingkan pada tahun lainnya yang mencapai 5,72 ton/ha. Penurunan ini disebabkan oleh adanya pengaruh El Nino yang terjadi pada tahun 2019 lebih kuat dibandingkan pada tahun 2015, sedangkan produktivitas padi tertinggi terjadi pada tahun 2015 mencapai rata-rata 6,11 ton/ha., Drought is a condition of lack of water availability in an area over a long period and affects the intensity of human needs. This drought study is used to monitor the level of drought that occurs, especially in East Java as an agricultural center, and compare the level of drought in the phenomenon of strong El Nino years, weak El Nino years, and normal years. This study uses the SPI index to calculate meteorological drought, VHI for agricultural drought and NDVI for drought vulnerability using 3 different years, namely 2015 as a strong El Nino year, 2017 as a weak El Nino year, and 2017 as a normal year for comparison. El Nino events cause high drought and more extended time than normal years. There is a difference in timing between meteorological drought and agricultural drought, and this is due to the time lag between rainfall and the appearance of symptoms of agricultural drought. The time lag between agricultural drought and meteorological drought is three months. Drought vulnerability in El Nino years has a higher and more stable vulnerability than in normal years, where too high vulnerability is less suitable as a place for cultivating drought-prone crops, such as rice. Rice productivity in 2019 was the lowest productivity compared to other years, reaching 5.72 tons/ha. This decrease was due to the influence of El Nino occurred in 2019, which was stronger than in 2015, while the highest rice productivity occurred in 2015, reaching an average of 6.11 tons/ha.

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.
