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

Soft soil is characterized by low bearing capacity and high degree of compressibility, which could potentially cause ground subsidence and slope instability in road construction. This study aims to analyze the stability of a road embankment and predict the magnitude of soil consolidation settlement in the Junction Bypass–Pekanbaru Toll Road Construction Project at STA 203+850. The methods employed were Terzaghi's one-dimensional consolidation method and numerical modeling using the finite element method (FEM). To determine which method more accurately represents actual field conditions, the calculated settlement values were compared with settlement plate monitoring data. The results showed that the consolidation settlement calculated using Terzaghi's method was 0.328 m, whereas the finite element analysis yielded a settlement of 0.171 m. These results were compared with the settlement plate measurement of 0.222 m, indicating that the finite element method produced a settlement prediction closer to the actual field conditions. The slope stability analysis resulted in a factor of safety of 1.94 using Culmann's method and 1.04 using the finite element method. Therefore, the finite element method provides a settlement prediction that more closely represents field conditions, while the embankment slope remains in a critical stability condition.
