Judul: Identifikasi Tingkat Kerawanan Banjir DAS Ciujung.
Abstrak: Banjir merupakan salah satu bencana yang memiliki dampak besar dan selalu mengancam beberapa wilayah di Indonesia. Faktor-faktor yang menyebabkan kejadian banjir di Indonesia antara lain curah hujan, penutupan lahan dan topografi. Penelitian ini dilakukan untuk mengidentifikasi daerah rawan banjir DAS Ciujung pada berbagai periode ulang curah hujan. Pemetaan kerawanan banjir dilakukan dengan melakukan overlay terhadap parameter Topographic Wetness Index (TWI), penutupan lahan, dan periode ulang curah hujan maksimum. Parameter tersebut diklasifikasikan menjadi lima kelas yang kemudian dibobotkan berdasarkan prosedur pembuatan peta kerawanan banjir yang dikeluarkan oleh Badan Standardisasi Nasional. Hasil penelitian menunjukkan bahwa pada periode ulang curah hujan maksimum 2, 5, 10, 25, 50, dan 100 tahun daerah hilir DAS Ciujung termasuk daerah yang memiliki tingkat kerawanan tinggi. Pada daerah hulu tingkat kerawanan bervariasi. Distribusi tingkat kerawanan tersebut dapat diidentifikasi melalui pola parameter Topographic Wetness Index (TWI), penutupan lahan, dan periode ulang curah hujan maksimum.

Judul: Evaluation of Topographic Wetness Index and Normalized
Difference Water Index for Identifying Flood-Prone Areas in Ciliwung Watershed
Abstrak: Bencana banjir dapat memberikan dampak besar dan merugikan beberapa wilayah di Indonesia. Salah satu penyebab banjir adalah penutupan lahan dan topografi. Penelitian ini dilakukan untuk mengevaluasi penggunaan Topographic Wetness Index (TWI) dan Normalized Difference Water Index (NDWI) dalam memetakan daerah rawan banjir. Pemetaan kerawanan banjir dilakukan berdasarkan nilai TWI dan NDWI, serta hasil gabungan kedua indeks tersebut yang kemudian dilakukan overlay terhadap jenis tutupan lahan untuk melihat tingkat kebasahan berdasarkan jenis tutupan lahan. Proses random sampling dilakukan untuk melihat tingkat kebasahan masing-masing penutupan lahan secara adil. Hasil penelitian menunjukkan mayoritas tutupan lahan di wilayah kajian memiliki tingkat kebasahan sedang hingga tinggi. Hal tersebut disebabkan oleh topografi yang cenderung landai dan tingkat kerapatan vegetasi yang cenderung sedikit., Flood disasters can have significant and detrimental impacts on several regions in Indonesia. One of the main causes of floods are land use and topography. This study aims to evaluate the use of Topographic Wetness Index (TWI) and Normalized Difference Water Index (NDWI) in mapping flood-prone areas. Flood vulnerability mapping is conducted based on TWI and NDWI values, as well as the combined results of these two indices, which are then overlaid with land cover types to assess moisture levels based on land cover types. Random sampling is performed to assess the moisture levels of each land cover type. The research findings indicate that the majority of land cover types in the study area have moderate to high moisture levels. This is attributed to the relatively flat topography and low vegetation density.

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.
