Judul: Application of EPA SWMM 5.2 on Drainage  Channel Evaluation in Harapan Indah Complex Medan Satria District Bekasi City
Abstrak: Kasus banjir berulang setiap musim hujan di Indonesia. Kota Bekasi, khususnya Komplek Harapan Indah RW 20 hampir setiap tahun mengalami banjir dengan genangan setinggi 60 cm menjadi wilayah prioritas penanganan banjir. Penting untuk menilai kapasitas saluran drainase dan kesesuaiannya dengan volume limpasan air menggunakan model EPA SWMM 5.2 yang efektif menganalisis masalah limpasan di perkotaan. Penelitian ini bertujuan mengevaluasi kesesuaian saluran drainase dan memperbaiki saluran yang meluap. Penelitian ini terdapat luas wilayah ± 6,81 ha, menggunakan data dimensi saluran, curah hujan harian maksimum, dan peta kontur. Metode distribusi yang sesuai yaitu Log Pearson III dengan periode ulang 5 tahun, menghasilkan intensitas curah hujan rencana 267,88 mm. Pemodelan mencakup 20 subcatchment (SUB), 70 conduit (con), 48 junction (j), dan 2 outfall (Out). Puncak hujan terjadi pada jam ke-6 dengan intensitas sebesar 25,93 mm. Debit limpasan tertinggi pada Sub5 dengan nilai 0,07 m3/det. Terdapat luapan pada saluran drainase yaitu Con23, Con34, Con37, Con40, Con43, dan Con46 dikarenakan terdapat sedimentasi. Setelah dilakukan perbaikan menunjukan saluran yang meluap kini mampu menampung debit air yang masuk., The problem of flooding recurs every rainy season in Indonesia. Bekasi City, especially the Harapan Indah RW 20 Complex, experiences flooding almost every year with inundation as high as 60 cm, making it a priority area for flood management. It is important to assess the capacity of drainage channels and their suitability to the volume of water runoff using the EPA SWMM 5.2 model which effectively analyzes runoff problems in urban areas. This study aims to evaluate the suitability of drainage channels and repair overflowing channels. This study has an area of ± 6.81 ha, using data on channel dimensions, maximum daily rainfall, and contour maps. The appropriate distribution method is Log Pearson III with a return period of 5 years, resulting in a planned rainfall intensity of 267,88 mm. Network modeling includes 20 subcatchments (SUB), 70 conduits (con), 48 junctions (j), and 2 outfalls (Out). The peak rainfall occurred at the 6th hour with an intensity of 25,93 mm. The highest runoff discharge is in Sub5 with a value of 0.07 m3/det. There are overflows in the drainage channels, namely Con23, Con34, Con37, Con40, Con43, and Con46 due to sedimentation. After the improvement, it shows that the overflowing channel is now able to accommodate the incoming water 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.

Abstrak: Sheep meat is the god source of essential amino acids and other important nutrients for human growth. However, there is a controversial myth that mutton contains cholesterol which can generate a cardiovascular disease. Sheep m& is divided into milk lamb: lamb and muttoe milk lamb is derived h m pre-weaned lamb. Lamb is derived from post-weaned lamb with age is no more than one year. Mutton is derived from adult sheep. It has been known that the younger the sheep, the lesser the lipid content of the meat And so the cholesterol content of the meat.
