Abstract

Handling road damage by overlaying the old road surface layer and planning a drainage system to improve the area value of the Waemital-Kawatu road section, West Seram Regency. The aim of the research was to determine the thickness of the overlay layer and the channel dimensions needed by the Waemital-Kawatu road section, West Seram Regency. The data used are primary data and secondary data then analyzed using the 2017 Road Pavement Design Manual Method for Additional Pavement Layers and the Rational Method for Drainage, then data processing is carried out referring to these regulations. Based on the results of this research, it was obtained that the CBR of class A aggregate foundation layer was 54%. So that with a design life of 20 years and a traffic value on the design lane of 801,068.59, the pavement layer thickness (overlay) with AC-WC = 40 mm, AC-BC layer thickness = 60 mm, class A aggregate layer thickness = 400 mm is obtained. . The results of the calculation of the drainage channel for a 5-year return period obtained a planned rainfall of 134,259 mm, with a population growth percentage of 1.1% per year so that the population of Waemital Village in 2026 is 7,443 people. From the results of the analysis of the drainage system, it was found that the planned discharge of the drainage channel on the Waemital-Kawatu Road Section was 0.0635 m3/sec, and the discharge of the drainage channel on the Waemital-Kawatu Road Section was 0.078197 m3/sec, then it was found that the discharge capacity of the channel was greater from the design discharge, so that the plan dimensions are declared safe.

Abstract

In the world of construction services, labor productivity is one of the determining factors for the success of a development project. It measures the success or failure of a construction project in achieving its objectives. One way to increase worker productivity comes from worker attitudes by increasing worker commitment, satisfaction, and responsibility for work. Therefore, in efforts to analyze labor productivity, variables that might influence the level of productivity must be considered. This research was conducted to find out what factors influence labor productivity and to determine the influence of labor characteristic factors on worker productivity. The research was carried out by observing the productivity level of 15 workers and accompanied by filling out a questionnaire. From the data collection results, both productivity data and questionnaires were processed using the SPSS (Statistical Package for Social Science) version 26 computer program. Based on the results of the analysis of factors that influence productivity, including skill diversity (x1). task identity (x2) variable task significance (x3). Based on the results of hypothesis testing, skill diversity has a positive effect on productivity with a positive T count value of 2.630 > 2.160. Task identification has a positive effect on productivity with a calculated T value of 2.435 > 2.160. Task significance hurts work productivity with a calculated T value of -2.384 < -2.160. Based on the R square test, it can be seen that the characteristics of the workforce consisting of the variables skill diversity, task identity, and task significance simultaneously influence productivity with a multiple determination coefficient values of 84%, and the remaining 8.4% is influenced by other variables not included in this research.

Abstract

The number of residents in Ambon City every year has increased, therefore the number of increases in vehicle volume is directly proportional to the number of population growth, and in line with the increasing problem of traffic congestion. One of the traffic jams that occur in Ambon City is on the Kakialy road, which is caused by side obstacles due to unattended vehicle parking on the road, especially during rush hour or peak hours (during school and after school or commuting and returning from work). The existence of community facilities such as shops, fast food areas, hotels, and residential areas is also one of the triggers for road body parking which causes congestion on the Kakialy road section. Therefore, this study was conducted to find out how the performance of the Kakialy road section during peak and normal hours. The method used is a descriptive survey that uses data collection techniques in the form of observation and documentation studies for the calculation of capacity and speed on urban roads using the Indonesian Road Capacity Manual (MKJI) method. The results of data analysis show that the capacity of peak hours at 12.00-13.00 WIT) is 18,721 junior high school/hour and normal hours at 16.00-17.00 WIT is 15,037.8 junior high school/hour, with a vehicle density value (DS) at peak hours of 0.59. The average side resistance data in peak hours has a weighted frequency of 366.6 SMP/hour so it belongs to the medium side resistance class (M), and the average side resistance in normal hours has a weighted frequency of 148.7 SMP/hour, including the low side resistance class (L). So that after going through the calculation analysis process, it is concluded that the vehicle density value (DS) at peak hours (12.00 – 13.00 WIT) is 0.59 and is categorized in Level Of Service (LOS) C which means medium performance. While the vehicle density value (DS) during normal hours (16.00 – 17.00 WIT) is 0.45 and is categorized in Level Of Service (LOS) B which means good performance.
