Judul: Evaluation of Drainage Channels on Mangunsarkoro Road, Cianjur Regency, West Java
Abstrak: Masalah banjir atau genangan sering terjadi di jalan-jalan di Indonesia, termasuk di Jalan Mangunsarkoro, Kabupaten Cianjur. Tujuan dari penelitian ini adalah untuk mengevaluasi kondisi aktual saluran drainase di Jalan Mangunsarkoro dan mengkaji kesesuaian kapasitas saluran drainase dengan besarnya limpasan, dengan menggunakan model EPA SWMM 5.1. Penelitian ini menggunakan curah hujan harian maksimum selama 10 tahun. Hasil analisis dengan metode distribusi Log Pearson III menunjukkan curah hujan rencana untuk periode ulang 2 tahun sebesar 104,36 mm. Hasil pemodelan jaringan drainase menunjukkan bahwa lokasi penelitian memiliki 32 junction, 32 conduit, 2 outfall nodes, dan 52 subcatchment. Dari hasil simulasi terdapat 2 saluran yang meluap karena kapasitasnya tidak memadai. Untuk itu kedua saluran perlu diperbaiki dengan mengubah dimensi lebar menjadi 0.60 m dan kedalaman 0.80 m. Sebagai alternatif dapat dibuat gorong-gorong berdiameter 0.80 m., The problem of flooding or inundation often occurs on roads in Indonesia, including on Jalan Mangunsarkoro, Cianjur Regency. The purpose of the research were to evaluate the condition of the drainage channel on Jalan Mangunsarkoro, and to review the suitability of the drainage channel capacity to the runoff discharge, using the EPA SWMM 5.1 model. This research used the maximum daily rainfall for 10 years. The analyses result using Log Pearson III method showed that the planned rainfall of 2 years return period was 104.36 mm. Modeling result showed that the research location had 32 junctions, 32 conduits, 2 outfall nodes,and 52 subcatchments. The simulation results showed that 2 channels were overflowed because of the channels capacity problem. So to get the optimal capacity, the dimensions of the 2 channels should be changed with 0.60 m width and 0.80 m depth. Another alternative to solve the flood problems was to use drainage culvert with diameter of 0.80 m.

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: Egg is an animal origin food product which has high nutritional value especially protein. Cholesterol content of eggs is only found in egg yolk, on the other hand albumen does not countain cholesterol at all but high content of protein, so it can be used as a free cholesterol-protein sources. The application of albumen as egg instant drink effervescent tablet can be an alternative of protein source for people who need free-cholesterol diet. It can also become an egg product diversification.
