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.

Judul: Evaluation of Drainage Channels on Gardu Raya Road, Bogor City, West Java
Abstrak: Dalam pembangunan jalan raya, diperlukan prasarana berupa sistem drainase yang baik. Salah satu wilayah Kota Bogor yang mengalami masalah sistem saluran drainase adalah Jalan Gardu Raya. Permasalahan yang seringkali terjadi di wilayah ini adalah genangan air ketika curah hujan tinggi. Berdasarkan permasalahan yang telah disebutkan, penelitian ini bertujuan melakukan evaluasi kondisi saluran drainase di Jalan Gardu Raya, menentukan kapasitas saluran yang sesuai dengan limpasan yang terjadi serta menghasilkan desain saluran yang sesuai dengan kondisi lokasi penelitian. Evaluasi saluran drainase dilakukan menggunakan Software EPA SWMM 5.2. Perhitungan dilakukan dengan metode Log Pearson III dengan nilai curah hujan rencana sebesar 135,11 mm dengan periode ulang 2 tahun. Melalui pemodelan menggunakan EPA SWMM 5.2 didapatkan bahwa lokasi peneltian memiliki 34 subcatchment, 45 conduit, 45 junction dan 2 outfall. Berdasarkan hasil simulasi didapatkan bahwa terdapat saluran yang perlu diperbaiki dengan mengubah dimensi lebar saluran menjadi 0,60 m dan kedalaman 0,80 m. Serta perlu dilakukan galian tanah untuk mengatasi perbedaan elevasi pada saluran dari 188,4 mdpl menjadi 187,4 mdpl., In the construction of highway, infrastructure is needed in the form of a good drainage system. One of the areas in Bogor City that is experiencing problems with the drainage system is Gardu Raya Road. A problem that often occurs in this area is waterlogging when rainfall is high. Based on the problems mentioned, this research aims to evaluate the condition of the drainage channels on Gardu Raya Road, determine the channel capacity according to the runoff that occurs and produce a channel design that suits the conditions of the research location. Drainage channel evaluation was carried out using EPA SWMM 5.2 Software. Calculations were carried out using the Log Pearson III method with a planned rainfall value of 135,11 mm with a return period of 2 years. The simulation results show that the research location has 34 subcatchments, 45 conduits, 45 junctions and 2 outfalls. Based on the simulation results, it was found that there were channels that needed to be repaired by changing the dimensions of the channel width to 0,60 m and depth to 0,80 m. And it is necessary to excavate the land to overcome the elevation difference in the channel from 188,4 masl to 187,4 masl.

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.
