Judul: Analisis Kapasitas Penampang  Sungai Bekasi (Ruas Pertemuan Sungai Cikeas dan Sungai Cileungsi sampai  Bendung Bekasi)
Abstrak: Kota Bekasi merupakan salah satu kota yang sering mengalami peristiwa banjir. Untuk itu, Balai Besar Wilayah Sungai Ciliwung Cisadane melakukan pengendalian banjir di wilayah Bekasi melalui kegiatan normalisasi. Penelitian ini bertujuan untuk menganalisis kapasitas penampang sungai sebelum dan setelah dilakukan normalisasi. Analisis dilakukan pada ruas pertemuan Sungai Cikeas dan Sungai Cileungsi sampai Bendung Bekasi, dengan menggunakan model HEC-RAS. Pada penelitian ini, digunakan data curah hujan selama 15 tahun dari Stasiun Klimatologi Cibinong. Berdasarkan hasil analisis, metode distribusi curah hujan yang digunakan adalah log Pearson tipe III. Analisis dengan metode HSS Nakayasu menunjukkan debit banjir Sungai Bekasi pada periode ulang 25 tahun sebesar 665,81 m3/det. Hasil analisis menunjukkan bahwa terjadi luapan pada 102 stasiun dari total 116 stasiun. Pada 102 stasiun yang mengalami luapan, penampang sungainya mempunyai kapasitas antara 453,49 m3/detik – 665,71 m3/detik. Setelah dilakukan normalisasi, berupa pembuatan tanggul dan pengerukan dasar sungai, didapatkan bahwa kapasitas penampang semua stasiun di Sungai Bekasi dapat menampung debit banjir., Bekasi city is one of the cities that frequently experiences flood events. For this reason, the Ciliwung Cisadane River Basin Authority conducted flood mitigation in the Bekasi area by normalization activities. This study aimed to analyze the river cross-section capacity of the river before and after river normalization. The analysis was carried out at the confluence of Cikeas River and Cileungsi River to Bekasi Weir, using the HEC-RAS model. This study used rainfall data during 15 years from the Cibinong Climatological Station. Based on the analysis results, the rainfall distribution method used is log Pearson type III. The analysis result using the HSS Nakayasu method showed that the flood discharge of the Bekasi River with a 25-year return period was 665.81 m3/s. The analysis results showed that flooding occurred at 102 stations of the total 116 stations. At these 102 stations that overflowed, the river cross-sections had capacities of 453.49 m3/s – 665.71 m3/s. After the river normalization, namely construction of embankments and dredging of the riverbed, the cross-section capacity of all the stations along the Bekasi River could accommodate the flood discharge.

Judul: Drainage Evaluation of RW 02 Kotabaru Village West Bekasi Using EPA SWMM
Abstrak: Banjir sering kali terjadi di Indonesia, termasuk di Kota Bekasi di Perumahan Harapan Baru 2, Kelurahan Kotabaru, Kecamatan Bekasi Barat, dengan tinggi air mencapai 100 cm. Kejadian ini mengganggu aktivitas warga serta memaksa mereka untuk mengungsi. Evaluasi saluran drainase perlu dilakukan untuk mengidentifikasi penyebab banjir. Metode analisis hidrologi dan pemodelan menggunakan EPA SWMM 5.2 digunakan untuk menemukan titik-titik banjir dan menghitung kapasitas drainase secara akurat. Penelitian ini bertujuan untuk menganalisis penyebab banjir dan memberikan rekomendasi perbaikan. Hasil analisis hidrologi menunjukkan bahwa model distribusi hujan Log Pearson III dengan data satelit GPM, periode ulang 5 tahun, dan curah hujan 267,87 mm. Pemodelan SWMM 5.2 melibatkan 30 subcatchment, 126 junction, 168 conduit, dan 1 outfall. Simulasi 24 jam menunjukkan bahwa 5 saluran berwarna merah, dan profil saluran menunjukkan luapan akibat antrian aliran ke Sungai Cakung. Analisis kapasitas menunjukkan debit simulasi sebelum perbaikan mencapai 44,01 m³/detik. Setelah perbaikan, Sungai Cakung dan saluran perumahan berfungsi dengan baik tanpa adanya luapan. Rancangan Anggaran Biaya untuk perbaikan ini mencapai Rp70.634.573., Flooding is a recurring issue in many parts of Indonesia, including Bekasi. In Harapan Baru 2 Housing Complex, Kotabaru Sub-district, West Bekasi District, floodwaters can reach 100 cm, disrupting daily activities and forcing evacuations. Evaluating the drainage system is crucial to identify the causes of flooding and provide improvement recommendations. Hydrological analysis and modeling with EPA SWMM 5.2 can pinpoint flood points and calculate drainage capacity. This study aims to analyze flooding causes and suggest improvements. Using the Log Pearson III rainfall distribution model with GPM satellite data, a 5-year return period was chosen with 267,87 mm of rainfall. EPA SWMM 5.2 modeling identified 30 subcatchments, 126 junctions, 168 conduits, and 1 outfall. A 24-hour rainfall simulation showed 5 channels in red, signaling overflow. Analysis revealed overflow due to flow queues to the Cakung River. Capacity analysis confirmed this, with pre-improvement simulated discharge and Cakung River capacity reaching 44,01 m³/second. Post-improvement, no overflow or inundation occurred in the Cakung River and residential channels. The estimated budget for these improvements is Rp70.634.573.

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.
