Judul: Estimation of Rice Productivity (Oryza sativa L.) in Java Island based on Oldeman's Climate Classification Projection
Abstrak: Padi (Oryza sativa L.) merupakan sumber pangan utama masyarakat Indonesia yang membutuhkan genangan air pada awal pertumbuhannya, sehingga tanaman ini akan tumbuh sangat baik di daerah dengan curah hujan yang cukup tinggi. Proyeksi iklim dan pendugaan produktivitas padi di masa yang akan datang dilakukan sebagai salah satu upaya preventif untuk menghadapi kondisi perubahan iklim yang terjadi. Penelitian bertujuan untuk menganalisis sebaran zona agroklimat dan menduga produktivitas padi di Pulau Jawa berdasarkan hasil proyeksi iklim Oldeman. Data curah hujan spasial periode 2010-2018 digunakan sebagai baseline dan data curah hujan spasial hasil downscaling periode 2030-an digunakan sebagai periode masa depan yang akan diproyeksi dan digunakan sebagai periode pendugaan produktivitas padi. Decision Support System for Agrotechnology Transfer (DSSAT) adalah software yang digunakan untuk membuat crop model tanaman dalam melakukan pendugaan produktivitas padi. Hasil penelitian menunjukkan pola tipe iklim periode baseline sama dengan pola tipe iklim pada periode proyeksi. Secara umum, tipe iklim basah berupa tipe A dan B mendominasi bagian barat Pulau Jawa dan tipe iklim yang agak kering seperti tipe C dan D mendominasi bagian timurnya. Perubahan luas sebaran tipe iklim yang terjadi pada periode proyeksi 2030-an disebabkan karena terjadinya fenomena perubahan iklim. Pada hasil pendugaan produktivitas padi, varietas IRRI original memiliki nilai sekitar 4200 kg/ha, sedangkan varietas IR 64 menunjukkan hasil yang lebih rendah, yaitu sekitar 3580 kg/ha., Rice (Oryza sativa L.) is the main food source for Indonesian people who need waterlogging at the beginning of their growth, so this plant will grow very well in areas with high rainfall. Climate projection and estimation of rice productivity in the future are carried out as one of the preventive measures to deal with climate change conditions that occur. This study aims to analyze the distribution of agro-climatic zones and predict rice productivity in Java Island based on the results of Oldeman's climate projections. Spatial rainfall data for the 2010-2018 period is used as a baseline and spatial rainfall data from downscaling for the 2030s period is used as a future period that will be projected and used as a period for estimating rice productivity. Decision Support System for Agrotechnology Transfer (DSSAT) is software used to create crop models for estimating rice productivity. The results showed that the climate type pattern in the baseline period was the same as the climate type pattern in the projection period. In general, wet climate types such as types A and B dominate the western part of Java Island and slightly dry climate types such as types C and D dominate the eastern part. Changes in the distribution of climate types that occur in the projection period of the 2030s are caused by the phenomenon of climate change. In the estimation of rice productivity, the original IRRI variety has a value of about 4200 kg/ha, while the IR 64 variety shows a lower yield, which is around 3580 kg/ha.

Judul: Respon Produktivitas Tanaman Padi Terhadap Kekeringan di Kawasan Jawa dan Bali (Pendekatan Model Simulasi Pertanian Berbasis Spasial)
Abstrak: Drought is one of many factors that influence the productivity of rice crops. There are several ways to study the response of rice productivity to drought, one of them is by using Shierary-Rice model approach that is integrated with Geographic Information System. The result shows that 10% reduction in rainfall at crop area of Java and Bali will be followed by decreasing the rice-crop productivity by 5.8%. The response of rice crop productivity is also affected by rainfall patterns shown in the Oldeman climate classification. Oldeman agroclimatic zone A and B dominating Banten and West Java areas are relatively less susceptible (8% decrease in productivity every 10% decrease in rainfall) compared to the other C, D and E Oldeman agroclimatic zone (14% decrease in productivity for 10% decrease in rainfall

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.
