“…e. Comparing the pros and cons of each option f. Sorting the alternatives and criteria for each element in order of greatest weight to least weight. Hierarchy is used in determining the location where a rubber weir will be built, because the proposed site of the weir takes into account the activities of local residents and good topographical conditions [12]. So opinions from village officials and experts are needed so that the weir that will be built is in accordance with the needs of the residents and its function [13].…”

Rembang is one of the regency that was significantly affected by the drought since 2019. The areas affected by drought have gradually expanded so that the demand for raw water in Rembang is increasing. The flow of the Karanggeneng River which empties to the north of Rembang can be used to make rubber dams as a solution to overcome the shortage of raw water availability. The aim of this study is to determine alternative locations for rubber weirs to be built on the Karanggeneng River. The standards or criterias by which the place was chosen of the rubber weir, namely distance from the estuary, topographical considerations, distance from the Water Treatment Plant (WTP), operational ease of access and the interests of fishing boats. There are 3 alternative locations, namely Karang Village, Waru Tengah Village and Waru Kawisto Village. Data were obtained by conducting interviews with respondents consisting of experts and local residents. After that, the Analytical Hierarchy Process (AHP) is used to process the data. The research results show that the order of priority criteria for planning rubber weirs is the importance of fishing boats and Waru Tengah Village is the most prioritized location of a rubber weir’s construction.

Semarang has experienced floods every year, with a peak in the rainy season. At the end of 2022, there was heavy rain which caused the East Flood Canal River to overflow. As a result, the floods inundated several areas in Semarang City, including Kota Lama of Semarang. This study aims to determine the value of the designed discharge, the area of the flood inundation that occurred and the flood inundation map for return periods of 2, 5, 10, 25, 50 and 100 years. The methodology of this research consist of hydrological analysis, hydrological modelling with HEC-HMS and hydraulics modelling with HEC-RAS and integration with ArcGIS. In this study, it was found that for a return period of 2 years the planned flood discharge value was 153.7 m3/second with an inundation area of 406 Ha and a flood height of 17 cm to 68 cm, up to a return period of 100 years with a planned flood discharge value of 455.7 m3/second with an inundation area of 796 Ha and a flood height of 83 cm to 180 cm.

Central Java is one of the provinces in Indonesia that relies on the agricultural sector. The agricultural centre in the province is located in Cilacap regency. In order to improve agricultural products, adequate facilities and infrastructure are required, one of which is the Jepara Secondary Channel. Channels on the Secondary Channel Jepara majority is no longer worth using. So much agricultural land is less maximal in water utilization. On the Jepara secondary channel, there is no similar cross-section of channels; some use a cross-section of soil, stone, and concrete, and there is cross-sectional damage. In connection with the problem, a cross-sectional planning analysis of secondary channels needs to be conducted. Consider effective rainfall analysis, irrigation needs analysis, and open hydraulic analysis. The results obtained from the analysis should indicate that the discharge flowed by the existing channel (Qs) must be greater than or equal to the planned discharge (Q0). Based on the results, two channels cannot accommodate the discharge of water needs (Q0), namely in section 1 and section 6, so it needs to be redesigned. However, by analyzing cross sections along channels with a varied cross-section shapes. Then planned design for all fields by using alternative four. This is because using a cross-sectional combination of trapezoid and u-ditch 70x80 cm can shorten working time and make construction costs more affordable.
