Abstract

The aims of this study is to determine the correlation between vehicle traffic activity and the effect of sampling time on the SO2 and NO2 concentration in ambient air. The sampling location is on Jl. Senopati Yogyakarta. Sampling was carried out by an air absorbtion tool with 1.5-meter-high auxiliary from the ground. To measure SO2 using Pararosanilin method and Griess Saltzman method for NO2. The stages of this study begin with the preparation of TCM absorption solutions for SO2, Griess Saltzman absorbent solution for NO2, calibration curve manufacture, and vehicle volume calculation. Determination of concentration is done by UV-Vis spectrophotometer Thermo Scientific Genesys 20. Time sampling is divided into weekdays (Tuesday-Wednesday) and weekend (Saturday-Sunday) with sampling time on 03.00-04.00, 07.00-08.00 a.m, and 12.00-01.00, 04.00-05:00 and 07.00-08.00 p.m. The result of the study shows that the concentration of SO2 and NO2 in ambient air is not related (correlated) with vehicle activity at Jl. Senopati Yogyakarta,as well as sampling time that did not affected. The highest SO2 concentration was recorded at 232,05μg/Nm3 while the highest NO2 concentration was 17.9522 μg/Nm3. Both is not exceed of air quality standard 900μg/Nm3 and 400 μg/Nm3.

Abstract

Research proposal selection process involving lecturers at the Institute for Research and Community Service (LPPM) must be carried out proportionally and professionally in accordance with established criteria and standards for management, assessment and funding. However, there are problems faced by LPPM, namely the lack of reviewers, differences in assessment styles, the number of diverse scientific studies, and the element of subjectivity are some of the challenge factors when selecting research proposals. There needs to be a decision support system that can be used as an alternative decision making in conducting research proposal selection. In this study we used a combination of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Simple Additive Weighting (SAW) methods using five assessment criteria, namely: the ability of presentation and mastery of the material, the problem under study, research method, research output, and feasibility resource. Based on the results of the study, the results of the same calculation obtained by combining the TOPSIS method and SAW using 20 data samples with the value of accuracy between manual calculation and the system reaching 100%.
