Abstract

Frames are often used as essential elements in the construction of machines and various other engineering products. The strength of the frame is significant in ensuring that the structure can withstand operational loads when used. Frame failure can cause severe damage, accidents, and substantial financial losses, so evaluating the strength of the frame before production is a critical step in the design process. This study aims to analyze the mechanical behavior of the components or frames of the patchouli chopping machine based on the maximum stress, displacement, and safety factor of the designed frame. The research method using finite element simulation technology is an efficient approach to analyzing the performance of frame structures. By utilizing simulations, a comprehensive evaluation of various parameters such as stress, displacement, and frame safety can be carried out. This process helps predict the structure's response to multiple loads received by the system. The simulation results using the finite element method show that the L-profile frame 40x40x3 mm with a cross-sectional area of ​​307.863 mm2 can withstand a maximum load of 1000 N with a maximum deformation of 0.2479 mm, which occurs at the load center. The von Mises stress distribution shows that the stress that occurs in the L-profile steel is 28.8 MPa. This value is far below the material yield strength threshold of 207 MPa. The maximum Safety Factor value that occurs in the frame is 15 ul, and there is no safety factor value below 1. The simulation results show that the analyzed frame is safe and meets the specified design requirements

Abstract

One technology that can be used to move water from a low place to a high place is a water pump without the use of electricity and fuel (Hydraulyc Ram/Hydraulic Pump). A water pump without the use of electricity and fuel (Hydraulyc Ram/Hydram Pump) is an automatic pumping device that uses water to lift some of the water flow to a higher place. The energy source for water pumps without the use of electricity and fuel (Hydraulyc Ram / Hydram Pumps) comes from high pressure which is caused by the phenomenon of water blowing due to a sudden change in speed of the water flow by closing the valve, so this pump does not require an external energy supply such as fuel oil or electricity. This article presents a report on the design, manufacture and performance field testing of hydraulic pumps. The test results show that the pump design can drain 0.3 liters/second of water with a maximum head of 8.1 meters and a distance of 10.5 meters. By looking at the potential for its use which is quite broad, research to optimize this pump needs to be continuously carried out in order to obtain a design that is quite accurate in accordance with field conditions in Indonesia.

Abstract

Tujuan penelitian ini adalah menganalisis pengaruh gaya kepemimpinan transformasional dan budaya organisasi terhadap motivasi kerja serta dampaknya pada kinerja aparatur desa di Kecamatan Cot Girek. Sampel terdiri dari 120 aparatur desa. Data dikumpulkan melalui kuesioner online dan dianalisis menggunakan Structural Equation Modeling (SEM) dengan perangkat Analysis of Moment Structure (AMOS). Hasil menunjukkan bahwa kepemimpinan transformasional dan budaya organisasi berpengaruh signifikan terhadap motivasi kerja dan kinerja aparatur desa. Motivasi kerja berperan sebagai variabel pemediasi parsial antara kepemimpinan transformasional, budaya organisasi, dan kinerja aparatur desa. Temuan ini dapat menjadi informasi penting bagi pemerintah daerah dan desa dalam menyusun kebijakan untuk meningkatkan kinerja aparatur desa.
