Abstract
Due to geographical condition, Cengkareng is one of a well-known flood-prone area in West Jakarta, Indonesia Annual floods may occur due to the limited bank full capacity of the local drainage system. This flood causes a significant loss of both infrastructures and human life. One of the most significant efforts in reducing this flood risk is the improvement of Cengkareng Drain channel as the main drainage system in the area. Cengkareng Drain conveys the flow of Angke River and Mokervaart River into the Java Sea passing through Tangerang and Jakarta. This paper discusses about the contribution of several alternatives of improvement in reducing the related flood risk. The flood hazard is analysed based on the standard criteria of PUPR. The risk analysis is done in accordance to the BNPB guidebook. Based on this study, it is found that the drainage existing condition may cause a high flood risk level in 5 areas and an average risk level in 1 area. This flood risk could be reduced by applying both structural and non-structural mitigation efforts. It this case, it is found that structural mitigation of dike development combined with non-structural mitigation of local community capacity development is the most effective solution.

Published: April 2021

Abstract
The sediment of the mechanical impurities, salts, undecomposed gel, destroyed proppant is systematically accumulated after the hydraulic fracturing in the horizontal well. This process is negative for the well operation and requires additional flushing to remove sediment. If this sediment is not removed, then ultra viscous gelatinous crust is formed. The energy of the jet of the working fluid is insufficient to effectively destroy the resulting gelatinous mass in the wellbore. The paper analyzes the existing technological solutions and proposes a device developed by the authors, which allows the destruction of proppant sediments. Application of the device described in the paper will contribute to more efficient production of hydrocarbons after hydraulic fracturing.
