Abstract

The application of Internet of Things (IoT) technology in the agricultural sector is a key strategy to improve efficiency, productivity, and sustainability, particularly in sugarcane farming. This community service program aimed to design and assist the implementation of a soil monitoring system based on IoT in sugarcane plantations in the Blitar region. The developed system functions to monitor soil moisture, temperature, and conditions in real-time, and presents the data through a simple dashboard accessible to farmers. The program involved mentoring activities, including requirement elicitation, training, and evaluation of training in the field. The results show improved digital literacy and analytical capacity among farmers in managing their land more efficiently. Other than that, the program also fostered the formation of a farmer-led management group that plays a crucial role in sustaining the system. Positive responses from farmers and interest in replication from neighboring farming groups indicate that appropriate, accessible technologies can empower rural agricultural communities. This program is expected to serve as a model for people-centered and sustainable technology-based agricultural transformation.

Abstract

This paper investigates shear behaviour of reinforced concrete using multi-surface plasticity model. This analysis uses nonlinear finite element simulation using 3D-NLFEA finite element package. The experimental data adopted from the results of experimental test on eighteen beams where nine beams carried out by Bresler and Scordelis in 1963 and similar nine beams carried out by Vecchio and Shim in 2004. The constitutive model for the concrete material which used in this simulation is based on the plasticity-fracture model and considered the tension stiffening effect for the concrete. The result of the numerical simulation latter compared with the experimental test including load-deflection response, cracking pattern, and failure mode. Based on the analysis result, it was found that the load-deflection response shows slightly higher. For Bresler and Scordelis beams test, the mean ratio of prediction peak load to actual peak load from the experimental result and a coefficient of variation of 1.00 and 7.42%, respectively and for Vecchio and Shim beams test, the mean ratio of prediction peak load to actual peak load from the experimental result and a coefficient of variation of 0.92 and 4.04%, respectively. However, the cracking pattern and failure mode of the beam shows good result which is in compliance with the experimental test.
