Abstract

The foundation layers of road construction in general have many problems of land subsidence. Land subsidence does not occur only on the ground or the original soil. Decrease of soil may also occur on pile or soil. Less than optimal density of the soil or the choice of unsuitable heap material may be the cause of the land subsidence in the embankment. Land subsidence also occurred in the National Road Development Project Segment Giriwoyo-Duwet, Wonogiri, Central Java, Indonesia, causing a decrease in road elevation from planned elevations. Decreasing this elevation can cause the standards of the cleverness and comfort of the road not being met. This study explains the results of the analysis of the large decrease in soil that occurred. The analysis is done by two methods. The method is done by theoretical calculation and by analysis using plaxis software. The results of the analysis show that the characteristics of soil used as soil pile material is silt soil with high and soft plasticity characteristics. The analysis also illustrates the factors of land degradation due to poor soil characteristics, carrying capacity and soil density less than standard and weather factors. The magnitude of the decline that occurred showed a decrease of 3-7 cm from the observation on the location, 1,1 cm from the results of plaxis software analysis and 1,7 cm from theoretical calculations.

Abstract

Replacing the floor covering from carpet with vinyl is an effort to increase the comfort of room users and the effectiveness of carrying out maintenance. However, the use of vinyl and carpet as floor coverings for hotel rooms has an influence on thermal comfort. So it is necessary to analyze the effect of using vinyl and carpet as floor coverings on thermal comfort in hotel rooms. The research method used is descriptive quantitative. This research is in the form of measuring temperature, humidity, and lighting in rooms 204, 206, 222, and 224 Hotel Grasia Semarang. Rooms with vinyl floor coverings tend to be comfortable in the morning (-0,5 ≤ PMV value ≤ +0,5), during the day the thermal comfort can worsen (if PMV value ≤ -0,5 or PMV value ≥ +0,5), and in the afternoon tend to be comfortable. While rooms with carpet floor coverings in the morning tend to be comfortable, during the day
