Abstract

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic forming using V-bending dies process and Electrolytic zinc-coated steel sheet (SECC/JIS G 3313) material. The zinc layer on the galvanized steel surface should not be damaged during the material forming process. The zinc layer on the galvanized steel sheet will affect the metal forming process. This study uses an experimental design with four input parameters, namely v-die opening L (mm), punch angle (degree), punch speed (mm/minutes), and bending force (kN). The smallest spring-back was obtained in the 4th test sample: the v-die opening of 35 mm, the punch angle of 40o, the punch speed of 30 mm/minute, and the bending force of 7.50 kN. The minor spring-back degree was 1.67o. Meanwhile, the smallest spring-go obtained in the second sample, namely the v-die opening of 30 mm, the punch angle of 50o, the punch speed of 40 mm/minute, and the bending force of 7.00 kN, the minor spring-go degree of 0.92o was obtained. These results show that the best spring-back degree for SECC/JIS G 3313 material is obtained when the bending process is performed with the v-die bending parameter of 30 mm, punch angle of 50o, punch speed of 40 mm/minute, and bending force of 7.00 kN.

Abstract

Cahaya begitu penting bagi kehidupan manusia, cahaya juga memberikan penerangan untuk segala aktifitas bagi manusia. Umumnya lampu dikendalikan secara manual melalui saklar, akan tetapi masyarakat Indonesia ketika berpergian keluar kota yang cukup lama lampu dibiarkan menyala sampai pemilik rumah kembali dengan itu tidak efisien dalam penggunaan listrik. Sehingga dibuatkan sistem kendali lampu otomatis untuk mengontrol kecerahan dari lampu tersebut, sistem kendali lampu otomatis ini diatur otomatis oleh sensor cahaya berdasarkan dari sinar matahari. Pada prototipe dan sistem kendali lampu otomatis yang dibuat menggunakan metode logika fuzzy, cahaya dikontrol dengan menggunakan modul ac light dimmer. Penelitian yang dilakukan dengan pengujian selama 10 hari, tanpa menggunakan sistem konsumsi, daya yang dipakai sebesar 1,116 KWh. Sedangkan dengan menggunakan sistem kendali lampu otomatis yang didalamnya menggunakan metode logika fuzzy dengan konsumsi daya sebesar 1,444 KWh. Sistem kendali otomatis sangat cocok untuk dinyalakan selama 24 jam.

Abstract

Transportation is an important element in everyday life and serves as a means of connecting between places. Online motorcycle taxi services such as Gojek have penetrated all regions, enabling users to order transportation services such as motorcycle taxis, taxis and cars online through applications. With the large number of content tweeted by Twitter users related to the use of the Gojek application, therefore sentiment analysis is needed to determine user perceptions of a topic or event. This study aims to analyze people's responses to online transportation through data collected from tweets. The data is then classified into two sentiment classes, namely positive and negative. The classification results using the Naive Bayes algorithm show an accuracy of 91%, while the use of the SVM (Support Vector Machine) algorithm produces a higher accuracy, which is equal to 99%. This indicates that the SVM algorithm is more effective in producing higher classification accuracy than the Naive Bayes algorithm.Keywords: Sentiment analysis; Online transportation; Naive bayes; Support Vector Machine AbstrakTransportasi merupakan elemen penting dalam kehidupan sehari-hari dan berfungsi sebagai sarana untuk menghubungkan antar tempat.

Abstract

Image pattern recognition poses numerous challenges, particularly in feature recognition, making it a complex problem for machine learning algorithms. This study focuses on the problem of cow pose detection, involving the classification of cow images into categories like front, right, left, and others. With the increasing popularity of image-based applications, such as object recognition in smartphone technologies, there is a growing need for accurate and efficient classification algorithms based on shape and color. In this paper, we propose a machine learning approach utilizing Support Vector Machine (SVM) and Random Forest (RF) algorithms for cow pose detection. To achieve an optimal model, we employ data augmentation techniques, including Gaussian blur, brightness adjustments, and segmentation. The proposed segmentation methods used are Canny and Kmeans. We compare several machine learning algorithms to identify the optimal approach in terms of accuracy. The success of our method is measured by accuracy and Receiver Operating Characteristic (ROC) analysis. The results indicate that using the Canny segmentation, SVM achieved 74.31% accuracy with a testing ratio of 90:10, while RF achieved 99.60% accuracy with the same testing ratio. Furthermore, testing with SVM and K-means segmentation reached an accuracy of 98.61% with a test ratio of 80:20. The study demonstrates the effectiveness of SVM and Random Forest algorithms in cow pose detection, with Kmeans segmentation yielding highly accurate results. These findings hold promising implications for real-world applications in image-based recognition systems. Based on the results of the model obtained, it is very important in pattern recognition to use segmentation based on color even though shape recognition.

Abstract

Produktivitas  tanaman  cabai  bergantung  kepada  iklim,  lingkungan,  serta hama  dan  penyakit. Petani yang baru dalam budidaya cabai merah menghadapi beberapa kesulitan karena memiliki sedikit pengalaman dalam budidaya, sehingga sulit untuk mengidentifikasi jenis penyakit dan hama yang menyerang. Hal ini menyebabkan penurunan produktivitas. Selain itu, petani juga belum memiliki pengalaman dalam menangani masalah yang timbul pada tanaman yang mereka budidayakan. Dalam rangka membantu petani mengatasi masalah ini, SPK berbasis web telah dikembangkan. Sistem ini menggunakan metode Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Kriteria yang digunakan dalam metode ini adalah daun mudah mengkerut dengan warna mosaic kekuningan, daun mengkerut hingga menjadi ukuran kecil dan lebih tebal, bercak bulat berwarna coklat pada daun yang mengering, terdapat lubang pada bercak tua, dan pucuk daun yang berubah menjadi kuning jelas. Alternatif yang dipertimbangkan dalam penelitian ini  Daun Cabai " Penyakit Layu Bakteri ", Daun Cabai " Layu Pusertium ", Daun Cabai " Penyakit Virus Kuning ", dan Daun Cabai “Penyakit Bercak Daun”. Perhitungan dengan metode TOPSIS, Daun Cabai " Penyakit Virus Kuning" mendapatkan peringkat dengan nilai preferensi sebesar 2.0118. Penelitian ini disimpulkan bahwa metode TOPSIS dapat digunakan untuk mengetahui daun cabai dengan kriteria apa yang terbaik berdasarkan kriteria

Abstract

Technology has penetrated all fields, the technology in question is learning media and learning support applications. Especially in the world of Islamic boarding schools, which is religion-based education, so it balances religious education and technological education. With the pandemic, everything in education has changed, namely, what was previously only conventional and face-to-face-based, education that can be done in any condition that breaks the barriers of time and space. So training is needed to optimize the use of online-based learning support media. The training results from 30 out of 35 people successfully completed the training stages and the remaining 5 passed with improvements.

Abstract

This article demonstrates that the sinker electrical discharge machining (S-EDM) method can be enhanced using SPHC (JIS G 3131) materials with a hardened surface. During S-EDM, neither contact nor a cutting force exists between the electrode and the workpiece. S-EDM is advantageous because it eliminates mechanical stress, chatter, and vibration issues with traditional milling. S-EDM is widely employed, for example, in the manufacturing of molds for automotive and aviation components. Taguchi design and signal-to-noise ratio (S/N ratio) were selected to examine the impact of the input parameter model on the material removal rate (MRR). The Taguchi approach assessed three input parameters and three experimental levels. The parameters pulse current (I), spark time (Ton), and gap voltage (Vg) were chosen to evaluate the MRR performance of the S-EDM process with the SPHC-hardened workpiece material. Copper with a diameter of 10 mm is chosen as the electrode material. This study aims to determine the optimal MRR for the chosen input variables. Results indicate that a more effective pulse current value promotes debris removal from the machining zone and stabilizes following spark release, speeding the material removal rate (MRR). In the S-EDM machining process, the pulse current value significantly affects the MRR and is one of the most significant response variables
