Abstract

The use of solenoid magnets in welding processes has attracted attention due to their potential to influence the properties of welded joints. This research investigates the effect of the size of the magnetic induction solenoid on the tensile strength and impact toughness of welds between mild steel and medium carbon steel. Welding experiments were carried out using various sizes of solenoid magnets (0; 1.71mT; 2.11mT; 2.31mT; 2.60mT), and the welding results were tested for tensile strength and impact toughness. The findings show that the size of the magnetic induction solenoid has a significant effect on the mechanical properties of the weld. The larger induction size in this study increased the tensile strength of the welded joint, namely 431.576 N/mm2 without induction and 533.33 N/mm2 with induction. Meanwhile, the impact toughness of welded joints also increases, namely 95.92N.m without treatment and 217.35N.m with induction.

Abstract

This study aims to develop exit protocols that promote the autonomy of conservation farmers by applying a Flood Management model in specific river basins within Pandeglang Regency. The present work utilizes the C.I.P.P. (Context, Input, Process, Product) and U.S.G. (Urgency, Seriousness, Growth) methodologies to assess the long-term viability of land conservation initiatives executed by farmers. Contextual input, process, and outcome analysis of implementing the flood management model is conducted using C.I.P.P. At the same time, the Urgency, Severity of the challenges, and prospective growth resulting from this program are assessed using U.S.G. A study revealed that when applied in specific river basin regions, the flooding management program can improve farmers' capacity to adapt and mitigate against flood hazards. Successful application of community-based conservation measures has demonstrated favourable outcomes in land administration and the improvement of food security. However, the long-term viability of the initiative relies on an exit strategy that ensures farmers' autonomy without necessitating external support. This approach entails enhancing the capabilities of farmers, broadening their sources of income, and enhancing their ability to reach markets and employ technology. The findings of this study will likely function as valuable policy suggestions to improve the sustainability of land protection and flood management within the Pandeglang Regency.
