Judul: Potensi Cadangan Airtanah di DAS Ciliwung
Abstrak: Water is one of the human primary necessity. Development of water resources basically is the way to give an equal access to everyone to get water, so that they can live healthily and cleanly. Naturally Indonesia faces problem to fulfil water demand because of uneven distribution. Water availability is not in accordance with water demand in terms of both quality and quantity. Water are controlled and arranged for a lot of purposes, such as flood control and water supply. The research objectives were : (1) Identify characteristic of aquifer in Ciliwung river basin. (2) To analyze the ground water potential at Ciliwung river basin. In the upstream of Ciliwung river basin an aquifer was formed by sand, sand stones and sands brections In the middle Ciliwung river basin was formed by sandy-clay and sandy-brections and in the downstream was formed by sand and sandy-clay. The thickness of unconfined aquifer in the upstream was 10 – 45 m, in the middle was 10 – 41 m and in the downstream was 5 – 10 m. The confined in the upstream was 30 – 60 m, in the middle was 20 – 40 m and in the downstream was 20 – 40 m. Hydraulic gradient at upstream was between 0.0709 – 0.101, in the middle was 0.007 - 0.0709 and downstream was 0.004. Hydrauic conductivity in the upstream was 12 - 45 m/day, while in the middle and downstream was 0.08 – 12 m/day. The analysis result showed that in the unconfined aquifer groundwater potential in zone 1 (Gunung Mas – Cibinong) was 584,211.29 m3/day or 6.76 m3/sec and in zone 2 (Depok – Jakarta) was 131,208.55 m3/day or 1.52 m3/sec. Groundwater potential of the confined aquifer was in zone 1 (Gunung Mas – Cibinong) was 2,028,514.23 m3/day or 23.48 m3/sec ground water potention and in zone 2 (Depok – Jakarta) was 369,985.73 m3/day or 4.28 m3/sec.

Judul: Analisis Potensi Dan Ketersediaan Air Berdasarkanneraca Air Das Di Das Ciliwung Hulu  (Kasus Tahun 1995, 1996 dan 1997)
Abstrak: Pengelolaan suatu daerah aliran sungai (DAS) dengan baik merupakan sala1l satu earn yang tepat untuk mengatasi masalall kcsenjangan air baik menurut ruang (spasial) dan waktu (temporal). Selanjutnya strategi pengelolaan DAS dapat disusun untuk meningkatkan pemanfaatan keterscdiaan air aktual, salall satunya adalall untuk sektor pertanian. Penyediaan air bagi pengembangan sektor pertanian memerlukan infonnasi potensi keterscdiaan air secara kuantitas, kualitas dan kontinuitas. Informasi tersebut dapat diperoleh melalui analisis neraea DAS. Studi ini dilakukan di DAS Ciliwung Hulu dengan pertimbangan balnva DAS tersebut menghadapi masalall banjir di musim Ilujan dan kekeringan di musim kemarau, sehingga sangat bcsar dampaknya terhadap produksi pertanian di hulu dan keamanan pemukiman di hilir.

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
