The problem of flood inundation in the Kebon Agung River at the Medokan Ayu Village, Rungkut District Surabaya, is getting worse due to the conditions of topographic, soil properties, high rainfalls, rising sea tides and very significant changes in land use. The eastern part of Surabaya, which was formerly open space land and now developed into a residential area. Therefore in the area, there is often flood inundation when the rainy season due to lack of recharge areas and poor drainage facilities. The performance evaluation of the drainage system was carried out using the SWMM program that is combining hydrology and hydraulic analysis. Hydrology analysis is used to determine various rainfall return periods. The maximum rainfall data are collected for 18 years. The hydraulic analysis is used to obtain the data in the form of cross-section, roughness, and drainage channel capacity. The results of the evaluation of drainage system modeling with SWMM have obtained the inundation points, namely for channels K3-K4-K5- K6-K7-K8 on the right side and Ki2-Ki3-Ki4-Ki5 on the left side. Pemasalahan genangan banjir di Kali Kebon Agung di Kelurahan Medokan Ayu Kecamatan Rungkut Surabaya menjadi semakin parah karena kondisi topografi, sifat tanah, tingginya intensitas hujan, meningkatnya pasang surut air laut dan perubahan tata guna lahan yang sangat signifikan. Wilayah Surabaya bagian timur yang semula lahan terbuka kini berkembang menjadi daerah perumahan. Oleh sebab itu di wilayah tersebut sering terjadi genangan banjir saat musim hujan dikarenakan kurangnya daerah resapan dan fasilitas drainase yang kurang baik. Evaluasi kinerja sistem drainase pada wilayah tersebut dilakukan dengan menggunakan pemodelan SWMM yang megabungkan pemodelan hidrologi dan hirdolika. Analisis hidrologi digunakan untuk menentukan berbagai kala ulang hujan. Data curah hujan maksimum digunakan selama 18 tahun. Analisis hidrolika digunakan untuk memperoleh data berupa penampang, kekasaran, dan kapasitas saluran drainase. Hasil running SWMM didapatkan titik titik lokasi genangan pada saluran K3-K4-K5-K6- K7-K8 pada sisi kanan dan Ki2-Ki3-Ki4-Ki5 pada sisi kiri.

The existing drainage system of roads proposed to manage the quantity of runoff from the road only, while the quality remains uncontrolled. In fact the pollutants and waste originated from the road surface contains hazardous substances. Sustainable drainage system (SUDS) concept offers various structures to solve both quantity and quality problems of surface runoff from roads. One of the potential drainage structure is filter drain or infiltration trench develope along the right side and left side of road. It could be developed by retrofitting the existing drainage channel of the road. The objective of this paper proposes the design model of road drainage based on the concept of a sustainable urban drainage system. The model consists of U-ditch channel, reservoir, an infiltration well. The bottom of U-ditch channel completed with a number of holes to make it porous. The channel filled with aggregate to filter the runoff from the road before flow down into the reservoir beneath. The water is then discharged to infiltration well. The model was developed based on rainfall data and other physical characteristics in Ambarawa City, Semarang Regency, Central Java.The channel dimensions and the depth of aggregate filter were designed base on runoff volume. The relationship among rainfall, runoff volume, area ratio, and drainage dimension are obtained. The results concept of sustainable road drainage is obtained in addressing the quality and quantity of rainwater.

The University of Lampung area, especially in the Faculty of ISIP, FEB, and FT is a densely packed student area. This area has undergone many land-use changes. The condition of the land as a green open space has changed its function to become an area for lecture buildings and offices. One of the impacts is an increase in direct surface runoff and a decrease in the quantity of water that seeps into the ground, this condition causes flooding during the rainy season. To facilitate the rehabilitation of the drainage system in the University of Lampung area, it is necessary to redesign the drainage system of the University of Lampung area. Rehabilitation of drainage channels is carried out to resolve flood inundation points that occur during the rainy season. Rainwater that is channeled through drainage channels is directed to natural or artificial reservoirs. The collected rainwater is used to recharge groundwater through natural infiltration methods. The analysis carried out in this study includes hydrological analysis and analysis of the existing drainage sections and the solutions are given. The hydrological analysis aims to calculate the planned discharge using the rational method. Modeling with the application used in this study aims to determine the capacity of the water level in the existing channel. Based on the results of the analysis, in the area, the Faculty of Engineering experienced runoff and inundation. This situation requires rehabilitation of the Lampung University area drainage system.

Objective : To characterize patients with chronic subdural hematoma undergoing surgery and to identify prognostic indicators. Methods : We conducted a retrospective analysis of patients diagnosed with chronic subdural hematoma (CSDH) undergoing surgical treatment. We analyzed: age, period from trauma to diagnostic imaging, pre and postoperative Glasgow coma scale, type of surgery, associated comorbidities, use of postoperative drainage and outpatient treatment. Results : The sample consisted of 176 patients, 126 male and 50 female patients (ratio 2.5 : 1), ages ranged from six months to 97 years, with an average of 59.3 years. CSDH was caused by trauma in 52% of patients, with the time from trauma to imaging averaging 25.05 days; 37.7% were hypertensive patients and 20% had a neurological disease. Eighty-five (48.3%) patients were elderly and altered consciousness was present in 63% of cases. Of the 91 (51.7%) non-elderly patients, 44% presented with headache, altered consciousness occurred in 40% and motor abnormalities in 27.5%. The CSDH was located on the right in 41%, left in 43% and bilaterally in 16% of patients. Conclusion : the change of consciousness was the most common clinical alteration in the elderly and headache in non-elderly. The most associated comorbidity was the arterial hypertension and the most frequent cause, head trauma. The trepanation with two oriffices associated with a closed drainage system was the most used operating, with high efficacy and low complication rate.

Sidoarjo or Lusi mud has an area of ​​640 ha and an average embankment height of 10 meters and submerges three sub-districts, namely Porong District, Jabon District and Tanggulangin District. In 2018, the Sidoarjo mud embankment has decreased or subsided by up to 8.5 meters at several points, which was caused by the condition of the embankment which was almost full and caused the soil condition of the embankment to become unstable. For this problem, it is necessary to build a drainage channel at the edge of the embankment to overcome the overflow of the embankment and flow it to the Porong river which is on the south side of the Sidoarjo mud embankment. From the calculation of the planned rain discharge, it is found that R2 = 72.95 mm after the planned rainfall is obtained, then the next is to look for the flood discharge plan which then plans the dimensions of the channel on the west and east sides of the embankment after obtaining the dimensions of the channel, then the next is planning the resistance pond and draining it to the porong river. with Siphon Network Pipe

Slum Areas

The existence of injustice and inequality in access to the development results of the city. Slum areas have become one of the problems that exist in urban life. This automatically occurs as a result of a normal process called urbanization and development. Where many residents end up occupying non-residential areas due to their limited access. Seeing from the perspective of the access theory, how people live in the area is a form of their right to be able to utilize natural resources. One of these uses is used as a place to live. This study used a qualitative descriptive method, by taking several samples as a source of interviews. The arrangement of the slum area is now moving to another dimension, which is no longer forced evictions, but how to organize and change the residential area to be habitable. There are several indicators used in seeing a residential area that is said to be unfit for habitation. Upgrading slum areas have been able to change areas that were previously unfit to be better and able to meet indicators of the feasibility of residential areas in general. This step is also how the community continues to strive to gain access to the area. Kampung Jodipan and Kampung Tridi have changed their appearance, and have improved the quality of their living environment, with tidier, cleaner, and more affordable access to public services. Apart from the results of this research, there are still some problems, one of which is the uncertainty of land rights, so that they will not know the future of the area they live in now. The guarantee of land ownership is important to fight for equal rights to state services, state recognition, and the right to live in the area.

This study was conducted to assess the building coverage and environmental quality of residential area in Nkpor Uno Idemili North L.G, Nigeria. The study employed a descriptive survey design to find out level of compliance of buildings to planning regulations. One hundred and eighty (180) were interviewed using a modified instrument (questionnaire). The data collected were coded into SPSS and analyzed with descriptive statistics. The results showed that 72(40%) reported inadequate setback as a major effect of over built buildings, 55(30.6%) reported inadequate free air space, 37(20.6%) said inadequate ventilation and lighting. Also, the nature of drainage system provided in residential areas; 76(42.2%) has no drainage system, 70(38.9%) has close drainage system. The building coverage of residential houses in the study area; 60(33.3%) has their building falls under 51-75% for over built, 48(26.7%) has their building falls under 76-100% for overbuilt. For the factors influencing the percentage of area built upon, 57(31.7%) has greed and no money to acquire a large plot of land, 47(26.0%) has no land space to built their desirable house. Then, non adherence to provision of adequate ventilation and lighting in the residential houses in the study area affects the dwellers’ health and such factors can promote communicable diseases. In conclusion, it was observed that the compliance rate was not encouraging because the planning regulations recorded very low compliance as include set–back from property boundaries; inadequate free air space; lost of aesthetic values, and inadequate ventilation and lighting. Therefore, government should embark on enforcement of land use plan, and strategic plans for various towns and villages to accommodate its utilities and facilities.
