Abstract

Botanical pesticides are naturally occurring chemicals derived from plant sources such as leaves, flowers, roots or seeds. This material has the potential as a more environmentally friendly and sustainable alternative to chemical pesticides. In general, residents in Mangaran Village, Mangaran District, Situbondo Regency work as farmers. In controlling pests and plant diseases, chemical pesticides are usually used to overcome them. The negative impact of using chemical pesticides is that pests will become increasingly resistant to the pesticides given, so stronger pesticides are needed the stronger the attacking pests. This resulted in an increasing number of chemicals in the crops that farmers planted which had an impact on the health of both farmers and consumers. The purpose of this socialization regarding vegetable pesticides is to increase knowledge regarding the manufacture of natural pesticides to control pests and diseases in plants. The socialization and training that was carried out received enthusiasm from farmers and those who attended the socialization were 26 farmers represented by each hamlet. The socialization results obtained are encouraging farmers to produce vegetable pesticides and reduce dependence on chemical pesticides

Abstract

Most fishing vessels used by local fishermen in Puger are constructed from Fiberglass Reinforced Plastic (FRP). These vessels are still built using traditional methods, where the design is based on pre-existing models that are subsequently modified. As a result, the structural strength of the vessels when operating in the waters of Jember remains uncertain. Therefore, an analysis is required to determine the maximum load-bearing capacity of the vessel structure under marine operating conditions. This study involved field measurements and interviews with local fishermen to collect data on the vessel’s principal dimensions, geometry, cargo weight, and load positioning. The collected data were used to develop a structural model, which was then simulated using Ansys Workbench for Student 2024 Version R1 to analyze the loading conditions experienced by the vessel. The simulation results yielded Von Mises stress and deformation values for five different loading scenarios. The equivalent stress values obtained were 3.617 MPa, 2.8763 MPa, 2.8198 MPa, 3.4382 MPa, and 3.2877 MPa, respectively. Meanwhile, the corresponding deformation values were 0.41003 mm, 0.18602 mm, 0.17995 mm, 0.35096 mm, and 0.30843 mm. The analysis indicates that the highest equivalent stress occurred under the first loading condition, with a value of 3.617 MPa, which remains below the allowable stress limit of the material, defined as 9.46 MPa.
