Abstract

Jalan Tongkol area, Seketeng District, Sumbawa Regency, NTB. This is a road frequently used by residents. The drainage channel on Jalan Tongkol, Seketeng District, is unable to withstand the flow of air during heavy rain. This writing aims to analyze the feasibility of existing channel dimensions and identify the causes of the current accumulation of air conditions. This study was carried out by carrying out hydrological and hydraulic analysis. Hydrological analysis includes rainfall data, rain intensity using the Mononobe formula and flood discharge using the Rational formula. Next, calculate the flood discharge by expanding the Catchment Area area, the flow coefficient value and the rain intensity during the concentration time using the equation Tc=Td+To. The rainfall value used to calculate rainfall intensity is the average maximum daily rainfall value from 2011 to 2020 at the BBMKG Station in the Sultan Kaharuddin area, Sumbawa Besar.

Abstract

Abrasion that occurs in Sumbawa Regency, Utan District, Stowe Brang Village is caused by wave factors, land characteristics which are generally in the form of peat, silt and sand are very vulnerable to erosion due to waves. In addition to natural factors, abrasion can also be blamed on human factors. The variables used in this study consist of 2 of them, namely: (1) Natural Factors, (2) Human Factors. The purpose of this study is to describe the coastal condition of Stowe Brang Village, Utan District, Sumbawa Regency. The analysis method used is Descriptive Analysis with a combination of Quantitative and Qualitative. To assess the condition of damage to coastal areas, it is necessary to survey the location of mangrove vegetation conditions, how far the coastline is to the pond, and the condition of the river estuary at the site. Furthermore, based on the value of the coastal damage index, the prioritization of handling refers to SE PU No. 11 of 2021. Based on the results of the analysis, there are several factors that affect the occurrence of abrasion at the study site, including factors still lack of vegetation on the beach, flat land slope factors, sandy beach type factors and the absence of coral reefs, sea wave factors that are large enough. To get wave plan data requires wind data for 10 years, tidal data, topographic data and bathymetry. Based on the results of data analysis, the wave height of the 10-year plan with the Gumbel method is 0.4 m. The form of handling efforts that can be done is the addition of mangrove vegetation and can also be done by building coastal protection constructions such as breakwater construction with plain concrete blocks

Abstract

The incineration from the coal industry produces waste such as bottom ash and fly ash that can pollute the environment. The use of waste in particular produced by PLTU Kertasari district of West Sumbawa is still not optimal so there needs to be an alternative to address the problem. The study used experimental methods to obtain the composition of a mixture of additive fly ash as cement additive and bottom ash as a substitute for sand on concrete. The objective of the study was to find out the slump values, the Compressive Strength of concrete pressure at age 7 and 28 days on the variations of fly ash 0%, 20%, 40%. and 60% as well as to find the strength comparisons of the pressure concrete life 7 and 28. The study used a cylinder-shaped test object of 15 test objects where for each variation there were 3 testing objects. As for the result obtained is a slump value with additive fly ash producing the largest mixture at 0% variation that is of 11.5 cm. The Compressive Strength value of concrete produced at the age of 7 days is at a variation of 60% which is of 6,09 MPa. Whereas at the age of 28 days the highets compressive strength valeu of concrete was produced at the age of 28 days with a variation of 60% namely 13,02 MPa.
