Integrasi Metode Objective Tree Diagram dan Quality Function Deployment dalam Perancangan Hydraulic Ram Pump (Hydram Pump) untuk Sistem Distribusi Air Irigasi Ramah Lingkungan di Sumatera Barat

Abstract

This study proposes an integration between the Objective Tree Diagram (OTD) and Quality Function Deployment (QFD) methods in the design of a Hydraulic Ram Pump (Hydram Pump) for an environmentally friendly irrigation water distribution system in West Sumatra. The hydram method uses the potential energy of river water to drive the pump without the need for electricity or fossil fuels, thereby reducing negative environmental impacts. This study involved a design phase of Identifying user requirements, Developing an Objective Tree Diagram to decompose the ultimate goals, and Integrating Quality Function Deployment to link user requirements with technical specifications. The design results indicate that the hydram pump can be designed to meet the needs of irrigation systems in West Sumatra. With a minimum waterfall height of 0.5 meters, the hydram pump can produce a head of 10 meters. The inlet flow rate is designed to be a maximum of 0.0354 m³/second, while the outlet flow rate is 0.028 m³/second or approximately 2448 liters daily. Integrating OTD and QFD methods allows designers to comprehensively understand user requirements, connect them with precise technical specifications, and reduce the gap between design and actual needs. This research is expected to contribute to developing an environmentally friendly irrigation water distribution system in West Sumatra. By using an integrative approach of the OTD and QFD methods, the design of the hydram pump can be more targeted and meet user needs. The implications of this research can be utilized as a guide in designing efficient and sustainable irrigation water distribution systems while reducing negative environmental impacts in the region.
