Abstract

The purpose of this study is to investigate the failure and instability of slopes, control and evaluate treatments and create slope data in a geographic information system as a planning data base to determine the level of risk, hazard consequences and the distribution of slopes along the National road in Konawe Selatan district. In this study using the Bina Marga slope survey method, which is to provide a score or value for each parameter measured in the field and a database is made using a geographic information system (GIS) to state the level of slope risk using the Bina Marga standard value. The results showed that the slopes spread on the Awunio – Lapuko and Lainea – Awunio National roads were dominated by artificial slopes, namely 4 embankment points and 5 excavation points and 1 natural slope point. From the results of the investigation and data collection on the slopes, the data is processed using the formula R = 0.9.H + C. where R is the risk level value, H is the hazard value and C is the consequence value. The conclusion from the above research results is that the slopes at the study site are dominated by artificial slopes with slope characteristics of soil, sand and weathered rock so that the slopes are unstable and have a high level of risk.

Abstract

In supporting the success of infrastructure development, it is necessary to have good cooperation between owners, contractors and workers which must be supported by the implementation of a project management system. A construction project is a series of activities which are generally short-term, dynamic, with varying intensity of activities and limited funds. If the project construction implementation is not managed properly, it will become a conflict or dispute between the elements involved in project implementation. In the current reform era, improving the quality of public services is a demand for workers where workers have begun to understand their rights as workers/employees. The purpose of the study was to determine the contractor's performance and to determine the perception of construction workers on the services of the company PT. Konawe Multi Usaha. The results showed that the perception of construction workers on the company's services at the company PT. Konawe Multi Usaha is rated by workers in the category of Fairly Good. There are factors that influence the perception of construction workers' satisfaction on company service satisfaction by using the Customer Satisfaction Index (CSI) analysis, the value of worker satisfaction is 73.43%, which means that the level of worker satisfaction is in the Satisfied category
