Abstract

In the Cibitung - Cilincing Ramp 3-1 Toll Road development project, where the road alignment is an embankment construction with subgrade conditions that have dominant soil layers with sand and limited land. Then the implementation of subgrade improvement is carried out by comparing 2 methods, namely the first Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Sheet Pile with a length of 15 meters + Retaining Wall and the second Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Retaining Wall with Bore Pile D60 Int. 2 meters + Retaining Wall.The analysis of the two treatments used Plaxis with the results for the 1 year and 10 year consolidation of the two treatments meeting the requirements. The safety factor for the embankment slopes also meets the requirements. The results of the Horizontal Displacement in the first treatment are still very large, namely 6.73 cm, not in accordance with the AASTHO criteria of 3.8 cm and it can be seen from the profile bending moment on the Sheet Pile that the Sheet Pile is not pinched so that for this case the handling suitable is to use the second treatment, namely Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Retaining Wall with Bore Pile D60 Int. 2 meters + Retaining Walls

Abstract

Access to clean water is the right of every citizen that the government must fulfill, both the central government and local governments, through drinking water business entities, namely PDAM. The performance of a PDAM represents the quality level of drinking water administration in an area. Only now, the high loss of drinking water has become problematic for PDAMs in improving their performance. One of the PDAMs with a high loss of drinking water is PDAM Tirta Yapono, Ambon City, with a water loss rate of 69.85%. In this paper, an effort is made to reduce water loss in PDAM Tirta Yapono by establishing a DMA in the Wainitu Village based on the existing condition of the pipeline, along with the number of sensors and instrumentation needed. SCADA and asset management implementation are also designed to support DMA's performance in reducing water loss. SCADA's role in reducing water loss facilitates the implementation of step tests and automation of monitoring activities for the distribution process and water quality by placing several instruments in the distribution network. Monitoring with SCADA will provide accurate data. Then, asset management also plays a role in reducing water losses because the information contained in asset management is used as material for preparing a strategy to reduce water losses following the priorities and capabilities of PDAM Tirta Yapono.

Abstract

Construction activities in road infrastructure development are never separated from earthworks which often become obstacles due to differences in land contours due to excavation and embankment work which is closely related to geotechnical engineering. Embankment and excavation are very interesting things to study because they are closely related to slope safety factors and require special handling. In this research, we examine the use of geotextiles by comparing the handling using safes on embankment stability using PLAXIS Version 8.2 software. The results of embankment stability analysis with safes, settlement at 1 year consolidation was 5.6 cm and settlement at 10 years consolidation was 5.7 cm. in accordance with applicable criteria. The results of the analysis using 2 layers of geotextile showed that the settlement at 1 year consolidation was 4 cm and at 10 years consolidation was 4.1 cm, which is in accordance with the applicable criteria.. Meanwhile, the results of the slope safety factor using bract treatment at 1 year consolidation were 1.475 and the safety factor for 10 year consolidation was 1.478, not in accordance with the design criteria of 1.5. The results of the safety factor using 2-layer geotextile treatment at 1 year consolidation was 1.853 and the safety factor for 10 year consolidation was 1.855, which is in accordance with the design criteria of 1.5.
