Abstract

The increase in traffic flow that occurs in addition to causing traffic jams has an impact on air pollution and sound pollution. Noise caused by traffic can cause health problems in humans who are exposed to it and can be achieved in stages from physiological disorders, communication disorders, balance disorders, and deafness. Noise that occurs in the school environment that will interfere with learning activities and student comfort. The purpose of this study was to determine the levels in the SDN Pasar Lama 1 Banjarmasin and to know the composition of the traffic flow that passes through Jl. S. Parman, Banjarmasin City. The data needed in this study is primary data, namely traffic volume data and the exact data at the observation location. Traffic data and data are taken simultaneously for 1 day at 08.00 WITA – 10.00 WITA, with a time span of 10 minutes. The intensity is taken in the study room at a distance of 50 meters from the road. The tools used in this research are hand counter, stopwatch, and sound level meter. From the results of the analysis that has been carried out, the total traffic volume on JL S. Parman is 17,810 smp/hour with a motorcycle percentage of 66.47%. While the highest value was obtained at 68.88 dB and the lowest was 61.24 dB. From this result, it is located in a location that exceeds the standard stipulated in the Regulation of the Minister of the Environment No. 48 of 1996 is 55 dB. Additional handling of the school environment is needed to help control levels that occur by adding natural or artificial barriers. This is done so that what happens does not affect the comfort of students in learning activities. Handling can be in the form of artificial barriers and natural barriers.

Abstract

Kuat geser permukaan serta gesek antar muka pada tanah lempung berpasir dengan menggunakan perkuatan geotekstil dengan tipe (HRX250) dan nonwoven (TS600). Metode yang dilakukan dengan cara eksprimen skala laboratorium di Laboratorium Mekanika Tanah. Tujuan penelitian ini untuk menguji nilai kuat geser (f) dan nilai sudut gesek antar muka (δ) tanah lempung berpasir pelaihari menggunakan bahan geotekstil sebagai perkuatan dengan 3 model pembebanan dalam kondisi terendam dan tidak terendam air. Terdapat nilai rasio (δ/f) dan nilai sudut gesek antar muka (δ) pada tanah lempung berpasir yang berbeda-beda karena pengaruh dari permukaan geotekstil yang digunakan. Nilai rasio (δ/f) yang paling besar didapatkan dari menggunakan geotekstil woven kondisi terendam sebesar 1.080 dan nonwoven dalam kondisi terendam sebesar 1.090

Abstract

The utilization of waste from wood cuttings is uncommon, and one of the wastes that is rarely employed is the leftovers of galam wood or galam powder cuttings. On this basis, a study entitled "The Effect of Adding Galam Powder as a Substitute for Fine Aggregate in Normal Quality Concrete Mixtures" was carried out. In this study, the experimental approach was used as the research method. The percentage of galam powder waste in fine aggregate, which can range from 0% to 30%, is the independent variable in this study. Other aggregates, such as cement, fine aggregate, coarse aggregate, and water, are the study's dependent variables. The compressive strength of 28-day-old material in the normal combination has a compressive strength of 22.23 MPa, the V10 mixture has a compressive strength of 4.58 MPa, the V20 mixture has a compressive strength of 3.11 MPa, and the V30 mixture has a compressive strength of 1.41 MPa. Based on the findings, it can be concluded that using waste galam powder as a fine aggregate alternative has not been successful since the galam powder does not bind completely to the concrete

Abstract

The pile built on soft soil has a tendency to fail its submission (bearing failure). This is caused by soft soils to have a low carrying capacity to carry the burden of construction. If a pile must be built which must be completed in a relatively fast time and must be stockpiled on soft soil, can be overcome by reinforcing the soil using geogrid material so as to increase the carrying capacity of soft soil (bearing capacity) and stability of the pile. Analysis uses the element method to the help of plaxis software to find the value of safety, deformation, and voltage changes in the pile built on the soft soil strengthened by geogrid. From this study it was found that the Modeling Piles 2 without Geogrid got a SF 1,0668 value and using Geogrid got a SF 1,3349 value. The safety factor of the pile of land 2 is above 1.25 which means that landslides are rare even without geogrid or use geogrid.
