Abstract

Rural development based on agrotourism is booming in Indonesia to increase community income. The process of cultivating grapes as an agrotourism has stages from land preparation, variety selection, proper watering care, to the process of picking and processing the harvest. The Bangun Sari village community has begun to develop grape cultivation as one of the agrotourism objects. However, due to limited human resources and technology, the productivity of agrotourism plants in Bangun Sari village has not been going well. The results of the grape plants that are currently cultivated are not optimal and many grape plants have not grown well because the irrigation and watering system is not good according to plant needs. International community service activities carried out by lecturers at the Medan State Polytechnic and in collaboration with the Nilai Negeri Sembilan Malaysia Polytechnic aim to implement automatic irrigation methods for grape farmers in Medan City. Community service activities begin with the presentation of material on automatic irrigation and watering systems followed by the fabrication and installation process of equipment in the field. The results of this community service activity are in the form of increased knowledge and delivery of products in the form of automatic irrigation and watering installations that have been installed at the grape cultivation location. The construction of this automatic fertigation equipment can solve farmers' problems. Ultimately, increasing the fertility and yield of grape plants can have an impact on increasing income.

Abstract

High rainfall has two conflicting effects. On the one hand, it is beneficial because it has the potential to be used to replace conventional raw water sources. On the other hand, it creates disadvantages caused by flooding. The purpose of this study was to determine the design of a rainwater harvesting system based on the geometric model of the building and the rain regime in such a way that the collected water can replace the use of groundwater so far while at the same time reducing the urban drainage load. The sequential research steps include literature study, determining analysis parameters, designing a Rainwater Harvesting System (RHS) model, creating a spreadsheet-based application (simulation table) for analysis of the RHS's performance, collecting data, analyzing the RHS model using a simulation table, and making conclusions. The RHS simulation designed for the Polmed campus lecture building produces a tank capacity of 45 m3 with a water-saving efficiency of 25% and an efficiency of reducing peak rain runoff of 67.5%. The RHS analysis table resulting from this study can generally be used to design an RHS.
