Paper Title
The Selection of Alternative Relocation of The Upstream Glonggong River Due to Changes in Land Use

Abstract
The construction plan of a gas production and processing unit in Jambaran-Tiung Biru Gas Plant (JTB) project is within the catchment area of the Upstream Glonggong River. The plan of JTB Gas Plant right above the Upstream Glonggong River will have an impact on the disruption of the river's flow and function. Therefore, some of the Upstream Glonggong River segments need to be relocated so that the existence and function of the river is not disturbed.This research aims to find the best alternative in relocating the Upstream Glonggong River.The research methods is carried out through hydrological and hydraulic calculations. The selection of alternative relocation of the Upstream Glonggong River was carried out using the 9 criteria weighting method. The selection criteria for river relocation alternatives used are: 1) upstream channel bottom elevation, 2) channel bottom width, 3) water level, 4) freeboard, 5) channel height, 6) gas plan facility elevation (GPF), 7) supporting buildings, and 8) mitigation and risk. The analysis result shows that the alternative selection analysis based on the 9 criterias assessment indicate that alternative 2 (GPF Plant elevation +60.00 m, upstream channel bottom elevation +58.40 m, channel bottom width 6 m, drop structure, retention pond, and overflow) are the best alternatives relocation of the Upstream Glonggong River for the construction plan of the GPF Plant in Jambaran Tiung Biru.
