Abstract

Abstract Construction management work must take into account the composition of workers. recruitment of workers, direction of workers, supervision of workers and others. The composition of workers will affect work productivity. The better the qualifications of workers, the higher productivity of workers. The purpose of the study was to analyze the factors that affect worker productivity in reinforced concrete structures in the Ivory Medical Hospital construction project in the City of Bengkulu. Data collection methods use observation and data analysis using the Time Study method. Based on the calculation results obtained the value of worker productivity, namely for column formwork work; 8.92 m² / Oh, beam; 7.25 m² / Oh and plates; 24.32 m² / Oh. In column reinforcement installation work; 473.57 Kg/Oh, beam; 126.31 Kg/Oh and plates; 378.22 Kg / Oh and for column casting work; 50.44 M³/Oh, beam; 15.57 M³/Oh and plates; 5.14 M³/ Oh. The factors that cause the lack of productivity of workers in the work of installation formwork is the distance of the material sites and the number of workers, while the factors affecting reinforcement work are the weather and the position / location of the material which is very far from the installation site.

Abstract

Abstract Seluma Utara Sub district is one of the Sub districts in the Seluma District, where most of the population is working as farmers. This causes the availability of irrigation to be very important to help the community in creating and managing agricultural or plantation land. Along with the rapid development of the area resulting in changes in most of the regional data, especially the form of maps, where the old map has expired (out of date) if compared with statistical data that are currently available. This happens because for the visualization of data in the form of maps requires substantial funds and a relatively long time, so that there are still many areas that still use the old map for planning, implementation and evaluation of development, therefore a mapping of Irrigation Regional (DI) channels is made based. Geographic Information System (GIS) to support the data needs in the District of North Seluma, namely Di Pandan, Talang Empat, and DI Puguk. North Seluma District, Seluma Regency. Data collection for mapping using the Global Positioning System (GPS) is done by tracking or crossing the existing irrigation channels in the field. The results of tracking using GPS are inputted into GPS software and a display of channel information is found in the irrigation area. This map makes it easy for related parties to carry out maintenance and rehabilitation in order to increase agricultural productivity.
