Abstract:Floods that occurred in the city of Banjarbaru especially those that occurred in residential areas caused problems for the community as well as challenges for the government to evaluate the drainage channel in the settlement. The existing rainwater drainage channels need to be reviewed and developed so that they can accommodate the water flowing in the area. One of the settlements that had occurred in the city of Banjarbaru was a residential area in Cempaka Subdistrict, Cempaka Village, precisely on Jalan Getah Tunggal. The data needed in this study are rainfall data, land use data, topographic data and existing data on channel conditions at the study site. Rainfall data were analyzed by Log Pearson III, Gumbel and Iwai Kadoya methods, then tested by Chi Square to choose the distribution of statistics received. The rainfall data was analyzed into the intensity of hourly rain using the mononobe method. Rain intensity is analyzed using a rational method to get a plan debit (Qchannel). Furthermore (the plan) is compared with (Qchannel), and (Qexisting). Based on the calculation results obtained (Qplanning) of 0.76 m3/sec, (Qchannel) of 0.78 m3/sec, (Qexisting) of 0.0645 m3/sec, the comparison results are obtained (Qchannel)>(Qplanning), (Qexisting) <(Qplanning). So that it can be concluded that the causes of flooding and inundation are sediments as high as 70 cm which reduce the storage capacity of the initial dimensions of the channel

Abstract:The problem of providing clean water is currently a special concern for developed countries and developing countries. Indonesia as a developing country cannot be separated from the problem of providing clean water for its people. One of the main problems faced is the lack of available sources of clean water, the uneven distribution of clean water services, especially in rural areas and existing clean water sources that have not been utilized optimally. This study aims to analyze the clean water needs of PDAM Samboja which uses 2 pumps in the next 10 years (2028). By using primary and secondary data obtained from PDAM Samboja and a number of related references, it was found that the IPA clean water needs of PDAM Tirta Mahakam Samboja with 2 pumps, in 2018 amounted to 2,599.5 m3/day. With the estimated results of the number of customers in the next 10 years (2028), the number of water requirements is 3,048 m3/day. Therefore it is necessary to add 1 pump to the PDAM Samboja IPA so that it can still serve the needs of customers in the next 10 years

Abstract:Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A

Abstract:Stabilization is an attempt to improve the physical and mechanical properties of the soil so that it meets specific technical requirements. One method of stabilization is the addition of portland cement additives. This study aimed to compare the CBR values of soft soil of peat before and after stabilization with portland cement and to determine the effect of variations in ripening time on carrying capacity of soft soil peat. Soft peat soil used was taken from Handil Bakti Village, Alalak District, Barito Kuala District, South Kalimantan Province. Variations in the addition of cement levels used 5%, 10%, and 15%, while the variety of curing time starts from 7 days, 14 days and 21 days. In the results of the modified Proctor compaction test, the addition of cement levels in the soft soil of peat was shown to increase the maximum dry weight volume (?d) value continuously. While the value of optimum water content (?opt) has decreased which is not too significant at each addition of cement content. For the value of the soft soil type of peat mixed with cement, the increase in weight compared with the original soil type weight. In CBR Laboratory testing using modified Proctor compaction at 15% cement content addition and 21 days curing time, the maximum CBR value of the Laboratory was 18.039%. The addition of Portland cement has been shown to increase the CBR value and the carrying capacity of the soil
