Abstract

Menangkap ikan adalah mata pencarian yang ditekuni setiap hari oleh masyarakat pesisir pantai Katapiang Padang Pariaman Sumbar. Biasanya, nelayan menangkap ikan di tengah laut dan hasil tangkapan dibawa dengan perahu kedarat. Setelah perahu sampai dibibir pantai kemudian perahu yang berisi hasil tangkapan ikan di tarik ke darat bersama sama oleh kelompok nelayan secara manual menggunakan tenaga manusia. Proses tersebut menurut nelayan tidak efektif dan meminimalkan hasil tangkapan karena harus dibagi ke anggota penarik. Adapun tersedia alat penarik sederhana tetapi tidak layak pakai karena tidak terawat dengan baik. Tujuan pengabdian pada masyarakat ini adalah mengedukasi masyarakat tentang alat bantu penarik perahu melalui pelatihan singkat tentang alat penarik perahu, cara operasi dan perawatannya supaya alat dapat berfungsi dengan baik dan memiliki umur pakai yang lama. Metoda yang digunakan adalah metoda pelatihan langsung ke kelompok Nelayan mitra. Hasil yang didapat setelah pelatihan ini anggota kelompok nelayan mampu mengoperasikan alat penarik kapal dan mampu melakukan perawatan harian pada alat penarik perahu. Kata kunci: penarik perahu nelayan, alat bantu tarik, pelatihan pengoperasian mesin, nelayan, tangkapan ikan ABSTRACT Fishing is the daily livelihood of the coastal community in Katapiang, Padang Pariaman, West Sumatra. Typically, fishermen catch fish in the open sea and bring their catch to shore by boat. Once the boat reaches the beach, the fishermen manually pull the boat, filled with their catch, to shore together as a group. This manual process is considered inefficient by the fishermen, as it reduces their catch since it has to be divided among the pullers. Although there is a simple pulling device available, it is not in usable condition due to poor maintenance. The aim of this community service is to educate the community about the boat pulling device through a brief training session on its operation and maintenance, ensuring the device functions properly and has a longer lifespan. The method used is direct training for the partner fishermen group. The outcome of this training is that members of the fishermen group are able to operate the boat pulling device and perform daily maintenance on it. Keywords: fisherman boat pulling device, assistive pulling equipment, machine operation training, fishermen, fish catch

Abstract

The development of machine learning in predicting the mechanical properties of alloy steel has become an important research subject in recent years. This is due to the ability of machine learning to extract complex patterns from large and intricate data, which can be used to understand the relationship between chemical composition, microstructure, and mechanical properties of alloy steel. This research aims to design a machine learning model to predict the mechanical properties of low alloy steel, such as Yield Strength (YS) and Ultimate Tensile Strength (UTS), based on the percentage composition of chemical elements in low alloy steel and the heat treatment applied. The machine learning model in this study consists of 10 input variables and 2 target variables. The research compares the performance of 3 machine learning algorithms, namely Decision Tree (DT), Random Forest (RF), and Artificial Neural Network (ANN). The research findings indicate that the ANN algorithm model performs best in predicting the mechanical properties of low alloy steel. This model has Mean Absolute Error (MAE) values of 16.5 and 19.593 for predicting YS and UTS, Root Mean Square Error (RMSE) values of 19.111 and 22.005, and coefficient of determination (R) values of 0.964 and 0.947 for YS and UTS respectively. The modeling uses the ANN algorithm with an 80% training data and 20% testing data split, and applies the K-Fold Cross Validation method with a value of K=5. The best parameters obtained are a learning rate of 0.001, momentum of 0.1, and a hidden layer neuron count of 9. These results indicate that ANN has great potential in addressing the complexity and variability in material data. The implications of these findings are that the implementation of ANN in manufacturing and material engineering industries can enhance the accuracy and efficiency in material strength prediction processes, which, in turn, can aid in designing and developing better and more durable products.

Abstract

This study aims to design and develop a quail egg incubator utilizing an Arduino Uno microcontroller to regulate temperature and control the egg-turning motor. The incubation process requires precise environmental conditions, particularly consistent temperature and egg rotation, to ensure optimal hatching success. The Arduino Uno system is integrated with temperature sensors and a motor driver to automate these essential functions. The developed incubator was tested to monitor the system's stability and its ability to maintain the required incubation parameters. The results indicate that the automated control system effectively maintains the optimal temperature and performs egg rotation, contributing to improved hatchability rates. This research provides a cost-effective and accessible solution for small-scale quail egg incubation

Abstract

The aerodynamic design of a vehicle body plays a critical role in reducing air resistance (drag), thereby contributing to improved fuel efficiency. Aerodynamic resistance in vehicles is influenced by several parameters, including body geometry, auxiliary elements, and the orientation of the vehicle relative to the airflow. This study aims to analyze the effects of body shape variations and the addition of a spoiler on drag force reduction in a sedan-type vehicle. The methodology employed in this research is numerical simulation using Ansys Fluent software. Simulation results indicate that the model with a more streamlined geometry (Model C) produces a lower drag force compared to the model equipped with a spoiler. The drag coefficients obtained for each configuration are as follows: Sedan A — 0.780, Sedan B with a spoiler — 0.775, and Sedan C with an improved body geometry — 0.647. These findings suggest that optimizing body shape is more effective in enhancing the aerodynamic performance of a vehicle than the addition of external aerodynamic elements such as a spoiler.

Abstract

Traditional learning media tends to have limitations in providing interactive experiences that can stimulate better understanding. This is supported by changes in learning styles among students, influenced by extensive exposure to computers and the internet, leading students to prefer learning with the aid of visualizations. This research designs, develops, and tests a machine learning-based visualization tool integrated with the Streamlit framework to enhance students' understanding of the mechanical properties of materials. This visualization tool consists of four main features: data analysis, correlation analysis, 3D visualization, and prediction models using machine learning. The data used for training the machine learning model includes tensile test data of low-alloy steel, comprising mechanical properties, chemical elements, and heat treatment temperatures. The research results indicate that the visualization tool can illustrate the cause-and-effect relationships of parameters influencing the changes in the mechanical properties of low-alloy steel. Each feature in this visualization tool can be utilized to support the analysis of mechanical properties and improve students' understanding of material mechanical properties. Additionally, the visualization tool is evaluated by experts, with information accuracy scoring 4 in the good category, visualization quality at 4.25 in the good category, suitability for learning at 4 in the good category, and ease of use at 4.5 in the good category. Nevertheless, further research and development are needed to test and expand the use of this visualization tool in various learning contexts and other material fields.
