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

Hasil pembakaran dari industri batubara menghasilkan limbah berupa bottom ash dan fly ash yang dapat mencemari lingkungan. Pemanfaatan limbah khususnya yang dihasilkan PLTU Kertasari Kabupaten Sumbawa Barat masih belum optimal sehingga perlu adanya alternatif guna mengatasi masalah tersebut. Penelitian ini menggunakan metode eksperimental untuk memperoleh komposisi campuran penambahan fly ash sebagai bahan tambah semen dan bottom ash sebagai pengganti pasir pada beton. Tujuan dilakukannya penelitian ini adalah untuk mengetahui nilai slump, nilai kuat tekan beton pada umur 7 dan 28 hari pada variasi fly ash 0%, 20%, 40%. dan 60% serta mengetahui nilai perbandingan kuat tekan beton umur 7 dan 28 hari. Penelitian ini menggunakan benda uji berbentuk silinder sebanyak 15 benda uji dimana untuk setiap variasinya sebanyak 3 benda uji. Adapun hasil yang didapatkan berupa nilai slump dengan bahan tambah fly ash menghasilkan campuran terbesar pada variasi 0% yaitu sebesar 11,5 cm. Nilai kuat tekan beton terbesar yang dihasilkan pada umur 7 hari terdapat pada variasi 60% yaitu sebesar 6,09 MPa. Sedangkan pada umur 28 hari nilai kuat tekan beton terbesar dihasilkan pada umur 28 hari terdapat pada variasi 60% yaitu sebesar 13,02 MPa.

Abstract

Since 2020 the number of students at the Faculty of Environmental and Mineral Technology (FTLM), Sumbawa University of Technology (UTS) has increased, and along with the increase in the number of students, it will affect the growth of transportation users. This study aims to analyze the factors that influence FTLM students in using transportation, in this case, FTLM students choose to use private motorcycle vehicles. Data collection using questionnaires and field observations on 86 respondents taken based on random sampling techniques. The data were analyzed using the binary logistic regression method. This method has four model tests, namely assessing the overall model (Overall Model Test), testing the feasibility of the model (Goodness Fit Test), the coefficient of determination and the classification matrix. The results showed that there are 2 factors or variables that are the reasons for FTLM students to use private motorcycle vehicles, namely vehicle ownership and distance to campus.
