Ukuran citra adalah salah satu kriteria citra tekstur terbaik di samping nilai pikselnya. Pada penelitian ini, diusulkan metode untuk mendapatkan ukuran citra tekstur terbaik terhadap GNBC dengan optimalisasi interpolasi nearest neighbor (NN). Ukuran citra tekstur terbaik dengan nilai piksel hasil interpolasi tersebut membuat GNBC mampu membedakan citra tekstur pada setiap kelasnya dengan kinerja paling tinggi. Langkah pertama metode usulan tersebut adalah menentukan ukuran citra tekstur untuk pelatihan melalui kombinasi ukuran baris dan kolom pada proses optimalisasi. Pengubahan ukuran (resizing) semua citra tekstur asal dengan interpolasi NN adalah langkah penting berikutnya untuk mendapatkan citra tekstur baru. Langkah selanjutnya adalah membangun GNBC berdasarkan citra baru hasil interpolasi dan menentukan akurasi klasifikasinya. Langkah terakhir yaitu memilih ukuran citra tekstur terbaik berdasarkan nilai akurasi klasifikasi terbesar sebagai kriteria pertama dan ukuran citra sebagai kriteria kedua. Evaluasi terhadap metode yang diusulkan tersebut dilakukan menggunakan data citra tekstur dari dataset publik CVonline dengan melibatkan beberapa skenario uji coba dan metode interpolasi. Hasil uji coba menunjukkan bahwa pada skenario yang melibatkan lima kelas citra tekstur, GNBC dengan interpolasi NN memberikan nilai akurasi klasifikasi terkecil 89% dan terbesar 100% pada ukuran citra terbaik, masing-masing 14 × 32 dan 47 × 42. Pada skenario yang melibatkan jumlah kelas kecil hingga besar, GNBC dengan interpolasi NN memberikan akurasi klasifikasi 81,6% - 95%. Dari hasil tersebut, GNBC dengan optimalisasi NN memberikan hasil lebih baik daripada metode interpolasi nonadaptif lainnya (bilinear, bicubic, dan lanczos) dan principal component analysis (PCA).

A recent report by the Ministry of Communication and Informatics in Indonesia revealed that around 800,000 websites were involved in spreading false information, underscoring the seriousness of the problem. To combat this issue, researchers have focused on developing techniques to detect and combat fake news. This research centers on using IndoBERT-base-p1 for fake news detection and aims to enhance its performance through three methods to tune the hyperparameter value of the model namely: Bayesian optimization, grid search, and random search. After comparing the outcomes of the three hyperparameter tuning methods, Bayesian Optimization emerged as the most effective approach. Achieving a precision of 88.79%, recall of 94.5%, and F1-score of 91.56% for the “fake” label, Bayesian Optimization outperformed the other hyperparameter tuning methods as well as the model using the fine-tuning hyperparameter value. These findings emphasize the importance of hyperparameter tuning in improving the accuracy of fake news detection models. Utilizing Bayesian Optimization and optimizing the specified hyperparameters, the model demonstrated superior performance in accurately identifying instances of fake news, providing a valuable tool in the ongoing battle against disinformation in the digital realm.","PeriodicalId":31477,"journal":{"name":"Jurnal Nasional Teknik Elektro dan Teknologi Informasi","volume":"22 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140420059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in its implementation process, the QR-code-based attendance at a Bandung school demonstrates weaknesses. Absent students can fake their attendance for themselves or friends. This type of attack is known as fake QR code generation. This research proposes a security authentication system using the Rivest–Shamir–Adleman (RSA) encryption algorithm and the secure hash algorithm 1 (SHA-1) to secure QR code-based attendance applications from fake QR code generation attacks. The RSA algorithm encrypts QR code data to maintain privacy, while the SHA-1 algorithm ensures data integrity. Based on this method, the mutual authentication process between the QR code data generated by the student and the attendance reading application by the teacher can be established. The results obtained from a series of tests showed that the security system in the student attendance recording application that had been implemented at Madrasah Aliyah (MA) Al-Mukhlishin could detect and prevent fake QR code generation attacks. The test was conducted by changing the impact of the key length on RSA-1024 bits and RSA-2048 bits. The results showed that in RSA-1024 bits, energy consumption of 0.14 J and time of 1.66 s is more efficient than that in RSA-2048 bits, with energy consumption of 0.19 J and time of 2.09 s. Interestingly, if a higher level of security is required, the key length should be increased at the expense of some energy and time efficiency.","PeriodicalId":31477,"journal":{"name":"Jurnal Nasional Teknik Elektro dan Teknologi Informasi","volume":"15 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140435361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, many shopping centers do not have sufficient parking spot, causing customers to have difficulty in finding available parking spots. Research has been conducted to tackle the issue of finding available parking spots. Much of this research proposed the narrowband-Internet of things (NB-IoT) as a fog node. For communication purposes, this NB-IoT-based fog node has some shortcomings, such as security and privacy, lower data rate, higher cost in development, dependency with wireless system, and only covers one area. In this research, the fog computing was proposed to decentralize smart parking system by using Firebase to cover several areas or malls in one system and interface. Instead of using NB-IoT, this research employed decentralized local server as a fog node to deliver a fast data exchange. Firestore database (Firebase) was also used to secure, manage, and analyze the data in the cloud. Conjunctively, the Android application was created as a user interface to book and find the availability of parking spots. The Android application was built using Android Studio and implemented authentication to keep the data access secure and private. The testing scenario was done following the design unified modeling language (UML). The research results confirmed that the fog computing system successfully supported the decentralized smart parking system and was able to be implemented for covering several areas or malls in one system.","PeriodicalId":31477,"journal":{"name":"Jurnal Nasional Teknik Elektro dan Teknologi Informasi","volume":"9 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140439208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A notable number of individuals disregard mask usage or do so incorrectly. It is particularly concerning given that COVID-19 has high transmissibility, especially in crowded areas like shopping centers. Enforcement officers often face challenges in identifying those wearing masks improperly. Herein lies the significance of automated mask detection to aid enforcement officers in containing the spread of the virus. Hence, this paper aims to highlight the importance of automated mask detection in combatting COVID-19 transmission. Previous mask detection algorithms were intricate because they relied heavily on resource-intensive machine learning algorithms and libraries. These algorithms, however, failed to address the problem of incorrect mask usage adequately. Therefore, despite the apparent usage of masks, the virus managed to find transmission pathways. In contrast, this research focuses on creating algorithms that pinpoint improper mask usage and optimize resource utilization without compromising detection quality. The Haar cascade algorithm was utilized to detect faces and the support vector machine (SVM) was used to train the dataset. The model attained an average accuracy of 95.8%, precision of 99.7%, recall of 92.3%, and F1-score of 93.7%. The metrics aligned with prior studies, affirming their reliability. Nevertheless, limitations exist as the model faces challenges in detecting obscured facial features, requiring further research to enhance its detection capabilities. This research contributes to ongoing efforts to improve mask detection technology for more effective virus containment.","PeriodicalId":31477,"journal":{"name":"Jurnal Nasional Teknik Elektro dan Teknologi Informasi","volume":"14 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pembangkit fotovoltaik (photovoltaic, PV) sebagai pembangkit terdistribusi (distributed generator, DG) merupakan salah satu pembangkit dari energi terbarukan yang menjadi tren saat ini. DG merupakan pembangkit yang letaknya dekat dengan beban pada jaringan distribusi. Dalam penerapannya, PV DG akan memengaruhi besar rugi daya pada jaringan listrik yang sudah ada (existing), sehingga juga memengaruhi besar biaya rugi energi. Selain itu, ketersediaan lahan yang memadai juga diperlukan dalam pemasangan PV DG. Hal ini menyebabkan kerja sama antara pelaku usaha penyedia tenaga listrik PV DG dengan partner beban dilakukan secara berjauhan, sehingga menimbulkan masalah penyaluran. Pembangunan saluran distribusi oleh pelaku usaha untuk evakuasi produksi listriknya hampir tidak mungkin dilakukan. Sewa jaringan distribusi menjadi solusi yang menarik, yaitu melalui skema pemanfaatan bersama jaringan distribusi atau power wheeling. Penelitian ini bertujuan untuk melakukan studi penerapan power wheeling pembangkit PV pada sistem jaringan distribusi IEEE 33 bus, dengan mencari lokasi bus penempatan pembangkit wheeling PV yang menghasilkan total biaya rugi energi dan biaya sewa jaringan distribusi terkecil. Metode MW-km digunakan untuk perhitungan biaya sewa jaringan. Ketersediaan lahan tiap bus juga dipertimbangkan dalam penelitian ini. Hasil penelitian menunjukkan bahwa penempatan pembangkit wheeling PV di bus 8 menghasilkan biaya total rugi energi dan biaya sewa jaringan distribusi terkecil selama setahun. Hal tersebut menunjukkan bahwa penempatan pembangkit wheeling PV di sembarang tempat belum tentu menghasilkan total biaya rugi energi dan biaya sewa jaringan distribusi terkecil.","PeriodicalId":31477,"journal":{"name":"Jurnal Nasional Teknik Elektro dan Teknologi Informasi","volume":"92 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140461185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SST consists of a single-phase dual-active bridge (DAB) converter, which is scale-down the dc voltage level. The control objective of the DAB converter used in the SST is to control its output voltage. This control strategy consists of a proportional-integral (PI) controller and a single-phase shift (SPS) modulation. Numerous literatures have mentioned about the SPS modulation for the DAB converter. However, they do not provide procedures in implementing the SPS modulation in the real controller. This paper aims to develop the SPS modulation in the real controller of the STM32F446RE microcontroller. The proposed SPS modulation is based on a master-slave timer feature, which is available in the STM32 microcontroller. The development process and testing of the complete control strategy of the DAB converter were carried out in the hardware-in-the-loop (HIL) simulation using Typhoon HIL. This scheme speeds up the development of process and reduces the costs. The experiment in the HIL environment shows that proposed control strategy of the DAB converter consisting of the PI controller and the SPS modulation is successfully implemented in the real microcontroller of the STM32F446RE. The proposed control strategy of the DAB converter is capable of bidirectional power flow, which is useful for integrating distributed generators in the load side. Moreover, this control strategy can reject the disturbance caused by loads.","PeriodicalId":31477,"journal":{"name":"Jurnal Nasional Teknik Elektro dan Teknologi Informasi","volume":"368 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140480321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
