Abstract

PLTU Tanjung Jati B Jepara causes excessive environmental pollution, namely fly ash and bottom ash (FABA) waste. So this waste is very suitable to be used as a stabilizing mixture for ordinary embankment soil. The purpose of this study was to find the optimal value for the foundation layer, using an experimental method to examine the free compressive strength of the soil stabilizing material. By using a mixture of 50% FA + 50% BA and 60% FA + 40% BA with the percentage of cement addition of 3%,5%,7%,9%,11%,15%. The results showed that the highest stress value occurred in the mix design 50% FA+50% BA with a percentage of 9% cement, the highest stress increase was at a percentage value of 4,943 kg/cm2 during a 3 day curing period. With the highest field density value at T3 of 1,553 gr/cm3. With the results of the highest soil density R value at T3 of 123.247%. The UCS and CBR values ​​for the best comparison for the foundation layer increased with the addition of bottom ash composition and PCC content in the mixture.

Abstract

In the area of highway Kelet - Bangsri area, Kelet Village, drainage problems and flooding often occur along the highway during the rainy season. From the problems found that there are no drainage channels as a result of residential construction that does not pay attention to the drainage function and can result in damage to road construction. This final project analyzes drainage channels with the aim of knowing alternative flood management. The results of the hydrological planning calculations will be used as the basis for hydraulic analysis, rainfall calculations using the isohyet method. The hydraulics analysis was carried out using the HEC-RAS and EPA SWMM programs. Based on the results of the analysis of existing conditions, it was found that inundation occurs because the capacity of the channel is not able to drain the flood discharge, such as the dimensions of the channel that are not suitable so that new planning is needed. The results of the analysis of the EPA SWMM software are more effective to be used as an alternative for handling the right flood problem according to the condition of the Kelet - Bangsri Highway, Kelet Village, Keling District, Jepara Regency with the planning of the new drainage channel dimensions of B = 0.6m and H = 0.8m.

Abstract

The sedimentation process that occurs continuously will cause silting due to sedimentation which affects the decrease in capacity flow of river particles. Sedimentary particles carried by the river flow heading to the sea will cause deposition in the estuary area so that it will blocking the flow of rivers to the sea. Based on the data from the sediment sample test results, gradation of sediment particles in the Wiso river consists of fine sand (Fine Sand) to very fine silt (Very Fine Silt) the average soil type is silt and the value of The density of the sediment has an average of 2,613. As well as for the benefits of this type of Sedimentation can be used as a water-resistant material for reservoirs and construction dam building.

Abstract

In this research, the author used FABA (Fly Ash Bottom Ash) waste as an alternative to fine aggregate. This research can determine the physical properties of faba aggregate with the results of sieve analysis testing of faba aggregate which has a fineness modulus value of 2.34 which is included in the medium fine aggregate type. Testing for water content in faba fine aggregate in SSD conditions was 3.09%. Faba fine aggregate sludge content is 0%. Testing the organic substances on the faba fine aggregate showed that the NaOH color was reddish brown, because it needed to be washed first before being used as a concrete mixture. The face dry specific gravity of faba fine aggregate is 2.2 gr/cm2. Therefore, faba aggregate can be used as a substitute for sand because it has physical properties that meet the requirements as fine aggregate. Results The final compressive strength of faba concrete and normal concrete as a control at the age of 7 days and 28 days has reached the planned quality, but the compressive strength at normal concrete (control) is higher than faba concrete. With the results of the standard deviation values ​​at 7 days and 28 days, it is included in perfect workmanship condition because it has a standard deviation value of less than 3 MPa. The results of the concrete flexural strength test were only normal K300 concrete with a flexural strength of 4.60 MPa, which complies with SNI 2847:2013, namely producing a minimum flexural strength of fs = 4.4 MPa. Normal concrete has a much higher flexural strength than faba concrete, and the higher the quality of the planned concrete, the greater the resulting flexural strength of the concrete.

Abstract

Basically, transportation is very necessary to facilitate all activities carried out by humans. The development of land transportation, such as the development of public transportation, is very rapid from year to year, this also requires development and progress in terminals as one of the road transportation infrastructure for loading and unloading people and/or goods, as is the case at Jetak Terminal, Kec. Kaliwungu District. Kudus is a type C passenger terminal, but along with the development of transportation, this terminal has changed its function to a type B terminal, so it is necessary to develop the terminal in terms of capacity and infrastructure. The method used in this research is to record the number plates of public transport entering, parking and leaving the terminal. Before conducting research, first ask for a research permit letter from the campus and the District Government. holy in this case BAPEDA Kab. Holy. The position of the Jetak Terminal in the existing road network system can be said to be quite strategic because it is on the main city route that connects Kaliwungu District with other areas, both in the western part of the city and with areas in the eastern part. Jetak Terminal has an area of ​​6.750 m², which consists of the building area and public transport parking area. Jetak Terminal currently has a parking area used by angkudes, microbuses, AKDP and motorbikes. Based on the results of calculations and survey results in the field, the need for parking space at the Jetak Terminal is currently unable to serve existing needs, where many microbuses are waiting for passengers outside the terminal. As a form of solving problems at the Jetak Terminal, it is possible to develop the terminal by optimizing the existing land around the terminal so that it can be utilized for the development of the Jetak Terminal.
