Abstract

Market activity affects the surrounding traffic conditions. The characteristic of traffic on the road and environment in this research case is the interaction of motorists from godong market activity participants. With the location of the market located in the city center, Godong Market becomes a center of activity for activity actors that give rise to vehicle circulation between market visitors and road users. The purpose of this study is to find out the volume, LHR, traffic flow density and performance of Godong road segments for the next 5 years with a data retrieval period for how to survey traffic volume, LHR, and traffic flow density, data analysis methods using MKJI 1997.  Based on the results of calculations and analysis of the road segment, the peak hour occurred on Monday, December 27, 2021 with a period of 16.30 – 16.45 obtained a peak hour volume of 318.6 smp / 15 minutes and converted to 1274.4 smp / h, LHR 1522 smp / hour.  The capacity result (C) of 2755 smp / h and the degree of saturation (DS) = 0.46 which is still below the required value in MKJI 1997 which is 0.75 for urban roads, travel speed (V) = 35.18 km / h, average travel time (TT) = 13.30 seconds, Service level  (Level of Service/LOS)  Categorized as level C based on the results of the analysis of the performance prediction of the road segment for the next 5 years obtained results (F) = 1540 smp / hour and degree of saturation (DS) 0.59 with a growth rate of motor vehicles reaching 3.86% per year.  Based on the results of calculations that occurred in 2021, it is necessary to maintain the value of traffic flow and always monitor the volume of vehicles passing through the road

Abstract

This study aims to re – design the breakwater in the Kartini port of Jepara, which was originally a cube into a tetrapod shape so that the port pool becomes stable again. This data collection is done in a secondary way by requesting data from related agencies in order to launch this research. Secondary data used include wind data, currents, waves, tides and bathimetric maps. From the calculation of the data, it is obtained that the breakwater peak elevation is 7 m, the breakwater peak width is 3 m at the head and 2.54 m at the arm. For the unit weight of the breakwater protection layer of the head of W = 2.03 tonnes for the tetrapod, W/ 10 = 0.382 tonnes, W/ 200 = 0.019 tonnes for crushed rock. While for the arm the amount of W = 3.059 tonnes for the tetrapod, W/10 = 0.3059 tonnes, W/200 = 0.0153 tonnes for crushed stone. for the number of layers of protection per 10 m2 as many as 12 points on the head and 15 points on the arms.
