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 Debit Andalan dan Aliran Dasar DAS Ciliwung Hulu
Abstrak: Sumberdaya air sangat berarti untuk kehidupan manusia, bersamaan dengan peningkatan jumlah penduduk kebutuhan akan air bersih pun akan bertambah. Bertambahnya jumlah penduduk memiliki kecenderungan penurunan kinerja Daerah Aliran Sungai (DAS) yang disebabkan oleh adanya aktivitas manusia dalam pemanfaatan sumberdaya alam yang tidak bijaksana. Oleh karena itu, memerlukan kajian mengenai potensi debit sungai agar dapat mengetahui kinerja DAS dan ketersediaan air sungai dari waktu ke waktu. Tujuan dari penelitian ini adalah mengetahui kualitas DAS dan potensi debit Sungai Ciliwung hulu periode 2001- 2020 melalui perhitungan Koefisien Regim Aliran (KRA) dan Koefisien Aliran Tahunan (KAT), debit andalan probabilitas Q80% untuk irigasi, probabilitas Q90% untuk air baku dan PLTA dan probabilitas Q95% untuk pemeliharaan sungai, dan aliran dasar dengan metode pemisah aliran local minimum method. Hasil dari penelitian ini menunjukkan bahwa Sungai Ciliwung Hulu dalam periode 20 tahun (2001-2020) memiliki KRA dan KAT yang masih baik, debit andalan probabilitas Q80% sebesar 159.361.920 m3 /tahun, Q90% sebesar 118.365.120 m3 /tahun, dan Q95% sebesar 72.743.040 m3 /tahun. Debit aliran dasar (baseflow) pada sungai Ciliwung tahun 2001-2020 berkisar antara 1,97 m3 /detik - 16.20 m3 /detik dengan nilai Baseflow Index (BFI) berkisar 0,56-0,85.

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.
