Rehabilitasi Jaringan Irigasi Simo

Rehabilitation of the Simo Irrigation Network

Abstract

The Simo Irrigation Area (DI) in Tuban Regency, East Java, is a vital infrastructure supporting local agricultural productivity, particularly rice, corn, and secondary crops. However, the condition of this irrigation network has suffered significant damage due to the aging of the infrastructure, sedimentation, erosion, and climate change. This study aims to evaluate the effectiveness of supervision in the rehabilitation of the Simo DI, including aspects of time control, costs, work quality, and administrative procedures. The research method was carried out through field surveys, coordination with relevant agencies, technical planning, and construction supervision, which included channel normalization, mini pile installation, pile cap casting, embankment construction, and quality testing such as concrete slump tests and reinforcement inspections. The results of the study indicate that supervision plays a crucial role in ensuring that the rehabilitation process is carried out according to technical specifications and the established schedule. The rehabilitation of the Simo DI successfully restored the function of the irrigation channel, increased the efficiency of water distribution, and supported the agricultural productivity of the surrounding community. Thus, this project not only extended the life of the infrastructure but also contributed to food security and the welfare of farmers in Tuban Regency.
