STUDI KELAYAKAN INSTALASI PENGOLAHAN AIR LIMBAH (IPAL) DOMESTIK KAWASAN BENDUNG KOTA PALEMBANG
Abstract View: 2375 PDF Download: 2750Sanitation is a way of treating household waste to prevent humans from being exposed to it, free of harmful impurities and waste materials. The use of wastewater treatment plants is expected to be able to reduce pollution produced by domestic activities. Since the last five years, the city of Palembang has had several WWTPs that process domestic waste, but there have been a few problems that have occurred so that a study of these problems is needed in the field. The research method used in this study uses both quantitative and qualitative research. The results showed that the percentage of IPAL Bendung was 11.7% of newly used WWTP capacity and 83.3% of WWTP idle capacity. This shows that the idle capacity of the two WWTP Bendungs is very high, and it is necessary to increase the house connection. Based on the results of the studies that have been found, the WWTP Bendungs found problems with discharge and detention time.

ANALISIS SALURAN DRAINASE AKIBAT GENANGAN DI KECAMATAN ILIR TIMUR II KOTA PALEMBANG
Abstract View: 864 PDF Download: 1068Changes in land use in an area greatly affect water absorption. Inundation occurred in Ilir Timur II Subdistrict, Palembang City due to lack of maintenance of drainage channels and changes in land conversion which was originally land into a water catchment area, now it is a concrete or residential area. During the rainy season, water will fill residents' spaces in the form of puddles and floods, which will continue to increase surface runoff in the area. The impact of the inundation is very disturbing and detrimental to various parties. The purpose of this study is to determine the peak discharge, analyze existing drainage, and plan a new secondary drainage design. The data used are primary data, namely channel length measurement data, channel slope, and existing channel dimension measurement data. While the secondary data used is in the form of 10-year rainfall data obtained from two rain posts, namely the rain post in Sako District and the rain post in Ilir Barat I District, as well as land use data in the Fruit Watershed of Palembang City covering an area of 1222.89 hectares. Then carry out an analysis of changes in land use currently and calculation of peak discharge to plan the dimensions of the new secondary drainage channel. The current peak discharge (Qp) calculation results in the studied area are 24.4 m3/s. For the calculation of channel dimensions, it is planned to have a rectangular cross-section with channel dimensions at sta 0.00 - 672.80 m, namely the channel dimension height is 4.5 m, the channel width is 4.5 m, and the guard height (f) is 0.30 m. From the results of analysis and calculations it is known that with the dimensions of the new drainage design there will be no runoff along the secondary canal. It is hoped that this can be a reference in planning the drainage rearrangement in Ilir Timur II District to reduce frequent inundation.

ANALISIS PEMODELAN PEMILIHAN MODA TRANSPORTASI ANTARA SEPEDA MOTOR DENGAN ANGKUTAN UMUM
Abstract View: 2566 PDF Download: 2035Movement activities can cause the mode selection process. Tridinanti University, as one of the education centers in Palembang city is one of the centers of movement for students. The basis of this research aims to observe the behavior of student motorcycle users with public transportation and analyze whether mode selection is influenced by changes in cost and travel time. This research was conducted with data from the observation approach, questionnaire results, literature review and data processing with the SPSS program in describing the travel situation for the two modes. An overview of the composition of the characteristics of travelers from survey data, it is known that the general characteristics of users in the selection of modes are 81.14% of motorcycle user respondents while 18.86% of public transportation user respondents. Based on gender, male respondents were 57.43% while female respondents were 42.57%. The reasons for choosing modes for motorcycles are time considerations of 47.18% and cost considerations of 15.85% while the reasons for choosing modes for public transportation are cost considerations of 36.36% and time considerations of 13.64%. The mode selection model between motorcycles and public transportation obtained (Usp-Umk) = -0.767-0.011C-0.024T. When the condition of attribute difference is equal to zero, the probability value of motorcycles is greater than the probability of public transportation for the attributes of travel time and cost. The model obtained from regression analysis of all data has the highest R2 price of 0.88% or 88% of the influence of the two attribute factors considered and the remaining 12% is influenced by attributes that have not been considered. In addition to the 2 travel attributes included in this study, several other attributes could also be considered for testing such as safety, convenience, and other influencing factors.

Abstract View: 1060 PDF Download: 1104A fire is an unwanted disaster, in the framework of a post-fire building structure it becomes the basis for deciding whether the building structure can still be used or not. The rise in high temperatures in concrete structures will result in changes in concrete, the problem faced is how to handle post-fire buildings. From this explanation, this research will discuss the strength of concrete structures, especially the ratio of normal concrete to concrete that has been burnt with variations in duration of burning 1 hour, 2 hours and 3 hours under normal conditions. Concrete compressive strength testing was carried out when the specimens reached the age of 3 days, 7 days, 14 days, 21 days, and 28 days with cylindrical specimens and the flexural strength of concrete was carried out when the specimens reached 28 days. The number of concrete compressive strength test specimens is 36 unit, and the flexural strength is 12 unit. The normal quality of concrete used is 30 MPa. From the results of the analysis regarding the tests carried out on compressive strength, it can be concluded that from the results of the compressive strength tests of 1 hour, 2 hours and 3 hours it decreased by 26.83%, 41.46% and 59.67% compared to concrete normal, for the flexural strength test results of 1 hour, 2 hours, and 3 hours decreased by 33.25%, 66.75%, and 66.75% compared to normal concrete.
