A multitude of individuals and organizations depend on the perspectives or sentiments of the general populace while making decisions. Consumers generally rely on the viewpoints of other consumers when it comes to evaluating a product or service that they come across on social media sites. Through the surveillance of social media activity, companies that sell products and services can gain insight into the emotion expressed by consumers towards their offerings. Nevertheless, due to the limitations of writing, which lacks the ability to transmit nonverbal cues like gestures, facial expressions, and intonation, it is often challenging to identify implicit signs such as sarcasm. Sarcasm in a tweet can lead to an erroneous evaluation of the message's sentiment. Hence, it is crucial to conduct sarcasm detection, as it can greatly enhance the outcomes of sentiment analysis. This study assesses the efficacy of four transformer models, namely IndoBERT, RoBERTa, BERT, and BERT Multilingual, in detecting sarcasm in Indonesian on X platform. The experimental results demonstrate that the IndoBERT model, which has been specifically tailored for the task, gets an impressive F1-score of 95%.</em></p> Rizal Akbar Fitrianto, Arda Surya Editya ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1344 Mon, 01 Jul 2024 04:57:27 +0000 Prototype Design of Automatic Clothes Dryer Based on Atmega 328 Microcontroller https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1333 <p><em>Rain or bad weather has been a major problem for people who have clotheslines. Usually, clothes that are dried are often left out, so there is no time to pick up the clothesline when it rains or at night. To overcome this problem, an automatic clothesline control system is needed. By designing all the tools starting from the Light Dependent Resistor (LDR) Sensor as a light detector, water sensor as a rainwater detector, Stepper Motor as a driver, and Arduino Uno as a command maker. From the results of testing the tools that have been designed, the tool works every time the sensor reads the surrounding weather, such as when the sensor does not detect light, the Arduino will translate the surrounding conditions as dark, so that the Stepper motor will pull the clothesline inside. When the LDR sensor detects sunlight, the Arduino will translate the weather around the heat, automatically the clothesline will come out. Meanwhile, when the water sensor detects water droplets, it is translated by Arduino as rainy weather, then the Stepper motor will pull the clothespins in</em></p> Taufik Hidayat, Muhammad Akbar, Mursalim Mursalim ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1333 Mon, 01 Jul 2024 00:00:00 +0000 An Android Augmented Reality Application to Improve Cognitive Skills in Color Recognition for Down Syndrome children https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1359 <p><em>The objective of this research is (1) to develop and construct an educational Augmented Reality game that focuses on colour recognition for individuals with down syndrome, using markerless based method.

In this study, a PLTS practicum module design was created which contained two systems, namely On Grid and Off Grid. Where the purpose of this research is to make it easy for students to understand the differences between the two systems and the operation of the PLTS. In the On Grid system, the output of the inverter can be connected directly to the public electricity grid, in this case PLN by using a Grid Tie inverter which has synchronization in it. And also in this on grid system does not use a battery to store its power reserves. Meanwhile, it is different from an off-grid system, which uses a battery and cannot be connected directly to the public electricity network. In the Off Grid system the resulting voltage is 223.60 Volts and in the On Grid System is 236.83 Volts. Testing is carried out with 2 different loads on each system. It can be concluded that the PLTS system designed Off Grid and On Grid can run well.</em></p> <p><strong><em>Keywords:</em></strong> <em>PLTS, On Grid.

Pada saat ini sekolah SDIT Darul Hikmah dalam admininstrasi pembayaran SPP dilakukan secara konvensional yaitu mencatat dan mencari data pembayaran pada buku besar, sehingga kegiatan ini memerlukan waktu yang lama. Salah satu contoh bendahara mengalami kesulitan dalam mencari dan mencatat data baru, dikarenakan data pembayaran SPP menumpuk, selain itu data rawan mengalami kerusakan dan juga hilang. Selain itu proses pembuatan laporan yang belum terkomputerisasi mengakibatkan laporan disajikan dengan waktu yang lama dikarenakan harus kembali membongkar tumpukan. Tujuan penelitian agar siswa/orang tua/bendahara yang memiliki hak akses dipermudah dalam melakukan pembayaran dan pengolahan data pembayaran SPP secara cepat, tepat dan akurat. Metode yang digunakan adalah RAD <em>(Rapid application development)</em> karena cocok digunakan untuk penelitian dengan permasalahan administrasi pembayaran SPP. Karena dimulai dengan perencanaan kebutuhan, desain sistem, proses pengembangan dan pengumpulan feedback, hingga implementasi atau penyelesaian produk.Hasil dari penelitian ini merupakan sistem informasi administrasi pembayaran SPP untuk memudahkan siswa/orang tua dan bendahara melakukan pembayaran serta mengelola data dengan mudah dan laporan pembayaran SPP secara online.</p> Sinta Maria, Muhammad Muhammad, Vicky Setia Gunawan, Mukhtar Mukhtar ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1352 Thu, 11 Jul 2024 03:06:34 +0000 Interorganizational Project Urgency, Problems, and Solutions: A Systematic Literature Review https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1422 <p><em>Interorganizational projects involve two or more organizations to work jointly on a shared activity for a finite time. By doing interorganizational projects, organizations can be more competitive in increasingly varied and volatile markets. The benefits of interorganizational projects are followed by a difficult challenge that is to align difference between members of the project, so the benefits remain poor. A systematic literature review is performed to know what problems and solutions of an interorganizational projects are.

The dataset used consists of 2152 potato leaf images, categorized into three classes: early blight, late blight, and healthy. The selected model is ResNet-50, known for its ability to address the vanishing gradient problem, allowing for the training of very deep networks. The model training process involves data augmentation to enhance dataset diversity and prevent overfitting. Additionally, hyperparameter optimization was performed to maximize the model's performance. Evaluation of the model shows that ResNet-50 can achieve an accuracy of approximately 97% on the test data, indicating the model's high capability in accurately recognizing and classifying the condition of potato leaves. These results demonstrate the significant potential of using ResNet in plant disease image classification applications, which is crucial for decision-making in agricultural management. This research underscores the importance of deep network architectures and data augmentation techniques in improving the performance of deep learning models.</em></p> Made Doddy Pranatha, M Azman Maricar, Gede Herdian Setiawan ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://jurnal.unidha.ac.id/index.php/jteksis/article/view/1431 Thu, 11 Jul 2024 03:10:56 +0000
