Abstract

This research focuses on the classification of leaf types used in ecoprint production through the steaming technique by applying transfer learning on two widely recognized convolutional neural network (CNN) architectures, MobileNetV2 and ResNet50. Leaves have diverse applications in various sectors such as medicine, nutrition, and handicrafts. The study utilized a total of 600 leaf images from 15 species were collected from the surrounding environment and divided into 80% training and 20% testing sets. The aim of this study is to classify leaf types suitable for ecoprint quickly and efficiently, based on transfer learning with two CNN architectures, while incorporating fine-tuning. MobileNetV2 was selected for its computational efficiency, while ResNet50 was chosen for its ability to address the vanishing gradient problem and deliver high accuracy. Fine-tuning was employed to optimize model performance. Experimental results demonstrate that both architectures achieved strong performance, with MobileNetV2 reaching 94.12% accuracy and ResNet50 slightly outperforming it at 94.96%. Confusion matrix evaluation further confirmed these results, yielding accuracy, precision, recall, and F1-score values of 0.94, 0.95, 0.95, and 0.94, respectively. These findings highlight ResNet50’s superior performance over MobileNetV2 while affirming the effectiveness of both models in ecoprint leaf classification.

Abstract

This research was conducted to investigate evidence of an attack and to restore data after an attacker compromised an Open Journal System (OJS) service on a computer server. The method used in this research is a new approach developed from the Network Forensic Digital Life Cycle (NFDLC) method. This new method, known as KUAD, has several stages for collecting cyber-attack evidence and restoring it after the Gacor attack has occurred. The stages in the KUAD method include initiation, acquisition, execution, mitigation, and disposition. The novelty of this method, compared to the previous one, lies in the inclusion of the mitigation stage, which aims to restore data or documents after an attack. The tool used to detect the attack and find evidence of the attack is Tripwire, whereas the tools used to restore lost data include crontab, which runs backup commands with rsync in four steps. Tripwire can optimally detect attacks by displaying the number of data entries that were added, deleted, or modified. A total of 15,135 files in .docx, .pdf, and .jpg formats, deleted by the attacker, were successfully restored using this backup technique. The success rate of using this technique for post-cyber attack mitigation reached 100%.

Abstract

The acoustics of mosques present significant challenges due to their substantial spatial dimensions, highly reflective surfaces, and intricate architectural designs. These characteristics frequently compromise the clarity of sound, which is imperative for religious activities such as sermons and prayers. Despite global advancements in audio technology, centralized sound systems remain the most common choice in many mosques worldwide. However, this approach frequently results in issues such as uneven sound distribution, acoustic dead zones, and excessive reverberation. These factors significantly impact speech intelligibility and overall listener comfort. To address this critical issue, this study presents a systematic literature review spanning from 2003 to 2025. This research also incorporates an initial empirical survey conducted on 77 mosques in Indonesia to provide real-world validation. The survey results empirically corroborated the theoretical problems, revealing that 65% of respondents considered the sound unclear, and less than 50% expressed satisfaction with the current audio system. In light of these findings, the present paper puts forth an integrated optimization framework centered on speaker zoning. The framework synthesizes insights from acoustic engineering, psychoacoustics, and predictive modeling to create a holistic, data-driven solution. The model outlined herein provides a procedural framework for future research endeavors, emphasizing the utilization of professional acoustic simulation tools to achieve uniform sound distribution and high speech intelligibility. This methodological approach guarantees that the acoustic solutions are not only scientifically valid but also user-centric and relevant to the congregation's needs.

Abstract

During this pandemic, most of people’s activities are carried out through digital media. Both learning and working processes are using the video-conference platform, a platform deemed effective to facilitate the needs of distance communication. One of the limitations of using video-conference lies in difficulty in understanding emotional conditions based on solely camera video. Hence, speakers generally do not know their interlocutors’ feelings related to the materials being presented. Grounded on this issue, we examined a facial expressions-based emotion recognition tool. Micro expression is one of the micro-languages of communication. Machine learning model developed in this study was Deep Learning with Convolutional Neural Network (CNN). The library that was used was Keras, this was used to recognize micro expression pattern. Additionally, OpenCV was also used for the general face recognition process. Both libraries were operated using Python programming language. The result of the micro expression test involving thirty participants detected three types of facial expression, namely joy, sadness, and anger expression. However, face recognition applied in the present study still needed some improvements, especially for anger and sadness expression. With regard to joy expression, 89% of the expression were recognized. Based on the recorded data, it is necessary to improve the recordings criteria to obtain a clearer expression.

Abstract

Phytochemical screening is a preliminary stage in phytochemical research which aims to provide an overview of class compounds contained in the plants. The solvents used in this study consisted of distillated water, methanol, and n-hexane solvent. The purpose of this study was to determine the secondary metabolites in Red Lemongrass (Cymbopogon nardus (L.) Rendl.) extract using different three solvents. Red Lemongrass extract was prepared by maceration method using distillated water, methanol, and n-hexane (10 gram: 100 mL) as solvents. Results of the extract were subjected to a phytochemical screening test consisting of flavonoids, alkaloids, saponins, tannins, and triterpenoids. The results of phytochemical screening showed that alkaloids, flavonoids, triterpenoids, and saponins were drawn attracted to the distillated water solvent. Meanwhile flavonoids and triterpenoids were drawn to methanol solvents. In addition, triterpenoids were drawn to n-hexane solvents. The best solvent on maceration results will be used as a reference for testing the ability of the extract as an antidiabetic agent.

Abstract

Face detection in digital photos aims to get the face area in the digital photo. Usually, a lot of noise occurred when detecting faces in digital photos. This study applies the mean filtering method to improve digital photos by reducing noise. The accuracy of the mean filtering method is calculated using a confusion matrix, while the ability of this method is measured using the parameters of Mean Square Error (MSE) and Peak Noise to Signal Ratio (PNSR). Viola-Jones method was used to detect faces in this research. This method was chosen because it is one of the face detection procedures with high accuracy and good computational ability. Testing the mean filtering method obtained the lowest MSE of 9.33, while the highest PNSR of 14.37. The accuracy obtained by the mean filtering method using confusion is 90%. Based on these results, it can be concluded that the mean filtering method is feasible to be used in the case of face detection in digital photos.

Abstract

Digital Forensics (DF) is an essential tool for solving cases of crimes committed. Based on the type of action performed, DF is classified into static forensics and live forensics. The limitations of static forensics in this method are that data collection is carried out on permanent storage media, while processes in the running system are not obtained. On the other hand, live forensics provides an opportunity to perform data retrieval on the ongoing process. Generally, live forensics is used to acquire Volatile Memory (RAM) data but can be extended on mobile devices, internet/LAN networks, and cloud systems. Browsing in private mode leaves no traces and information about what the user has done during the browsing session. This feature is often used by criminals to hide the crimes committed or at least to slow down the forensic process. To overcome this problem, it is important to do forensics on RAM and Network Forensics to obtain evidence of these crimes. This study aims to conduct DF to obtain potential evidence in criminal cases of misuse of private browsing. The evidence is expected to be used as evidence in court. The parties involved in the crime can be prosecuted in court through such evidence. This research offers Digital Forensics Process Via Parallel Data Acquisition Technic. Parallel data acquisition is a method for retrieving data on a computer or other smart device when the computer or other smart device is on through two different data sources. The first source is RAM and the second is Network Traffic. A case study on a criminal case of misuse of private browsing with Digital Forensics Process Via Parallel Data Acquisition Technic was able to obtain evidence in the form of the website visited, URL, traffic timestamp performed, source address, destination address, transmission protocol, length (size of the packet transmitted), source last node mac address, destination last node mac address, source port, destination port, and detail information. The evidence is expected to be used to reconstruct a crime of misuse of private browsing.

Abstract

Kebutuhan ketersedian pengelola jurnal nasional yang bereputasi semakin banyak. Terlebih lagi sejak diberlakukannya regulasi kewajiban publikasi bagi mahasiswa sebagai syarat kelulusan. Namun demikian, tidak semua penerbit jurnal dapat mengelola penerbitannya sesuai dengan standar yang telah ditentukan, salah satunya adalah jurnal-junal yang dikelola oleh lembaga penelitian non pemerintahan (NGO). Penelitian ini mengangkat tentang pengembangan jurnal elektronik berbasis Open Journal System (OJS) dengan metode Agile dan Scrum sebagai kerangka kerjanya. Scrum menawarkan pengembangan sistem yang lebih fleksibel dan mampu beradaptasi yang berbasis kolaborasi.  Hasil dari pengembangan ini diuji menggunakan usability systemdengan kuesioner USE (Usefulness, Satisfaction, and Ease of use). Adapun hasilnya, 69,64% respoden menyatakan bahwa sistem pengelolaan jurnal elektronik MAARIF cukup mudah digunakan, cukup mudah dipahami dan cukup mudah dipelajari. 21,42% responden menyatakan sangat mudah digunakan, sangat mudah dipahami dan sangat mudah dipelajari. Hanya 8,9% responden saja yang menyatakan bahwa system pengelolaan jurnal elektronik MAARIF kurang mudah digunakan, kurang mudah dipahami dan kurang mudah dipelajari. Dengan demikian pengembangan jurnal elektronik berbasis OJS versi 3 menggunakan kerangka kerja Scrum dapat diimplementasikan dengan baik menggunakan 3 sprint dengan durasi 34 hari. AbstractThe need for the availability of reputable national journal managers. Especially since the enactment of regulation on publication obligations for students as graduation requirements. However, not all journal publishers can manage their issuance in accordance with predetermined standards, one of which is a journal that is managed by a non-governmental research institute (NGO). This study raised the development of an Open Journal System (OJS) based electronic journal with the Agile and Scrum method as its framework. Scrum offers the development of systems that are more flexible and adaptable based on collaboration. The results of this development were tested using the usability system with a USE questionnaire (Usefulness, Satisfaction, and Ease of use). As for the results, 69.64% of respondents stated that the electronic journal MAARIF management system was quite easy to use, quite easy to understand and quite easy to learn. 21.42% of respondents said it was very easy to use, very easy to understand and very easy to learn. Only 8.9% of respondents stated that the electronic journal MAARIF management system was less easy to use, less easily understood and less easy to learn. Thus the development of OJS version 3 electronic journals using the Scrum framework can be implemented properly using 3 sprints with a duration of 34 days.
