Abstract

From land value data sourced from the Central Bureau of Statistics of Jepara Regency that in Panggang Village, Jepara District, the transfer of land use for buildings is very high, which shows a percentage of 70.98%, therefore resulting in an open area in Jepara Regency for rainwater infiltration, especially in the main route segment is reduced, resulting in flooding and puddles in the city center location. Floods that occur are 40 cm to 80 cm high when it rains in the urban center area, there are several inundation points in the Jepara square, Kartini street, and Jepara's Chinatown area, and several other roads. The channel in Panggang Village is one of the infrastructures that supports the functioning of an urban system in Jepara City. In the existing channel along the Wiso River area, inundation often occurs every rainy season, so it is necessary to conduct a study to analyze the capacity of the drainage channel. The data used in planning is secondary data. Secondary data was obtained from the schematic drawing of the drainage channel and data regarding the dimensions of the channel and hydrological data. The hydrological and hydraulic data obtained were then analyzed to obtain the design discharge and drainage channel capacity. The design discharge is calculated using the rational method and the channel capacity is calculated using the HEC RAS ​​4.1.0 and EPA SWMM 5.1 software modeling. This study examines Drainage Channel Capacity Analysis to evaluate flooding based on the existing condition of drainage channels that affect the occurrence of flooding using HEC RAS ​​4.1.0 and EPA SWMM 5.1 software models. HEC RAS ​​4.1.0 software. Based on the results of hydrological analysis, the distributions chosen are Gumbel Type I Distribution and Log Pearson Distribution Type III. In the fit test, it was concluded that the Log Pearson Type III distribution method met the requirements because the Dmax value of -0.0202 was less than Do 0.41. and hydraulic analysis obtained by software HEC RAS ​​4.1.0 and EPA SWMM 5.1. at the 1 year return period there are 2 points that experience flooding and 4 points that are able to accommodate flood discharge. The flood points are scattered in several areas in Panggang Village, namely Jl. RA. Kartini and Jl. Youth. In dealing with flooding, it is necessary to re-plan the drainage for the 10-year return period in order to create security and comfort for local residents.

Abstract

Irrigation System Performance Index (ISPI) is often used as a parameter in making decisions about the use of irrigation canals. The increase in rice production is dependent on a good condition of physical infrastructures, including the main building, the carrier canal and the buildings on the carrier canal. Performance assessment of Physical Infrastructure and Plant Productivity in Sungapan irrigation area of Pemalang Regency indicated that the physical infrastructure performance in 2012 - 2022 was 38.42%, increasing 3.22%. While the performance assessment of Plant Productivity was 14.96%, increasing 2.99%. Based on the multiple regression analysis using simultaneous test (F), the Physical Infrastructure component was indicated to influence the plant productivity. Meanwhile, based on the partial test (t), the physical infrastructure component partially did not have a significant influence on the plant productivity

Abstract

Cement, as a concrete-forming material, is a contributor to CO2 emissions in the world. Reducing cement and substituting fly ash and silica fume as concrete substitution materials in the manufacture of concrete makes green concrete without lowering the quality of the concrete. Concrete in the marine environment is frequently destroyed by severe environmental elements, such as seawater penetration; hence, high-performance concrete materials are required. This research aims to analyze the effect of adding fly ash and silica fume on concrete compressive strength and permeability. The specimens made were then immersed in freshwater and seawater. Analysis of the compressive strength test result shows that the compressive strength values ​​for the samples treated with freshwater or seawater have exceeded the expected compressive strength of 30 MPa. The permeability test on the test object resulted in the supplementary fly ash to the concrete immersed in freshwater having a good value, i.e., the water penetration was below that required by DIN-1045, namely 5 cm. The penetration of concrete with fly ash impressed in seawater is good only in concrete with a 10% fly ash variation. The water penetration value still meets the requirements in concrete with silica fume for all variations with freshwater and seawater treatment.
