Abstract

Micro-expressions are facial expressions that occur inadvertently to hide true feelings (emotional leaks). Although previous studies used the entire face area and all frames in the video dataset, this resulted in relatively long computation time and data redundancy. The main contribution of this research is to apply recognition micro-expression analysis using a comparison of apex frames with manual (handcrafted) and random sampling of frames and applying feature point tracking to the brow area and corners of the lips. The method for forming feature points in the facial area uses Discriminative Response Map Fitting (DRMF), then facial feature points are tracked using Kanade-Lucas-Tomasi (KLT). This feature point tracking produces motion feature data as feature extraction data. Finally, a comparative analysis of the classification method using the Support Vector Machine (SVM) and MLP-Backpropagation was conducted using the CASME II dataset. The experimental results of this study show significant results with an accuracy of 81.3% on MLP-Backpropagation and an average computing time of 1.45 seconds for each video. From the results of this study, information on the apex phase can contribute information that is very important for facial micro-expression recognition.

Abstract

One of the challenges faced by micro-businesses like Kopi Combre in the village of Sumberdem, Wonosari District, when they want to use packaging for their products is selecting packaging that is unique and appealing to consumers. The primary goal of this community engagement project is to provide guidance in designing packaging structures and labels suitable for the micro-scale industry, particularly for Kopi Combre. The method involves community engagement and incorporates literature studies and information analysis. This study covers aspects such as coffee product attributes, packaging structure design, and labels. The findings indicate that the most suitable packaging type for the micro-scale industry is the Pouch packaging, while the packaging and label design will feature dark colors and include information about the coffee product and a unique brand.

Abstract

Ekspresi mikro merupakan ekspresi wajah yang terjadi secara tidak disengaja untuk menyembunyikan perasaan sebenarnya (emotional leakage). Penelitian sebelumnya menggunakan seluruh area wajah dan seluruh frame pada dataset video, hal ini menghasilkan waktu komputasi tergolong lama dan terjadinya redundancy data. Kontribusi utama penelitian ini menerapkan analisa pengenalan ekspresi mikro menggunakan perbandingan frame apex dengan pilihan manual (handcrafted) dan secara acak (random sampling) dan menerapkan pelacakan titik fitur pada area alis mata dan sudut bibir. Discriminative Response Map Fitting (DRMF) sebagai metode yang membentuk titik fitur dan selanjutnya dilakukan pelacakan titik-titik fitur wajah dengan Kanade-Lucas-Tomasi (KLT). Hasil pelacakan titik-titik fitur tersebut menghasilkan data motion features sebagai data ekstraksi fitur dan dilakukan analisa perbandingan metode klasifikasi menggunakan Support Vector Machine (SVM) dan MLP-Backpropagation menggunakan dataset CASME II. Hasil eksperimen penelitian ini menunjukkan hasil yang signifikan dengan akurasi sebesar 81,3% pada MLP-Backpropagation dan waktu komputasi rata-rata 1,45 detik pada setiap video. Hal ini menunjukkan bahwa informasi pada fase apex memberikan informasi yang penting untuk pengenalan ekspresi mikro pada wajah.

Abstract

Workshop desain grafis menggunakan Canva di SMA Integratif PPAI Al- Karomah Kabupaten Malang dilaksanakan sebagai respon terhadap rendahnya literasi digital dan keterampilan desain di kalangan santri, meskipun mereka memiliki minat tinggi terhadap media sosial. Kegiatan ini bertujuan membekali santri dengan kemampuan dasar desain promosi digital melalui metode studi kasus dan Workshop praktis. Materi yang diberikan mencakup pengenalan Canva, strategi konten Instagram, serta prinsip desain seperti layout, warna, dan tipografi. Hasil observasi menunjukkan peningkatan pemahaman dan antusiasme peserta. Evaluasi dilakukan berdasarkan kualitas desain, namun penilaian berbasis unggahan Instagram tidak optimal karena keterbatasan akses perangkat. Temuan ini menegaskan pentingnya pelatihan berbasis praktik yang adaptif terhadap kondisi pesantren. Secara keseluruhan, Workshop ini berkontribusi pada peningkatan literasi digital dan menjadi langkah awal menuju pemberdayaan ekosistem digital pesantren yang mandiri dan berkelanjutan di era transformasi digital.

Abstract

This research develops a real-time facial micro-expression recognition system, focusing on analyzing the onset and apex phases of micro-expression on the Spontaneous Activity and Micro-Movements (SAMM) dataset. Micro- expressions are very brief (0.04 - 0.2 seconds) facial muscle movements that often occur when a person is trying to hide emotions. The developed system aims to improve computation time efficiency and micro-expression recognition accuracy by optimizing feature extraction techniques and selecting more specific facial areas, including facial components such as eyebrows, eyes, and mouth. This research successfully improved the computation time efficiency by 51.96%, almost half the time required by the previous method. In addition, this study shows an increase in efficiency compared to previous studies, with an increase of 34.3% for SVM with Manual Sampling technique and 32.6% for MLP-Backpropagation. In the Random Sampling technique, SVM efficiency increased by 6.1%, but MLP-Backpropagation accuracy decreased by 4.8%. This method achieved 77.9% accuracy for MLP- Backpropagation, which is higher than the previous method. This research contributes to accelerating micro- expression recognition systems and improving accuracy, which opens opportunities for real-time emotion analysis applications such as lie detection or human behavior monitoring in a broader context.

Abstract

Abstract - Various threats that occur in the field are a problem for individuals who are faced with human rights law where personnel must make decisions quickly and accurately, the innovation of the Bola wrap weapon can paralyze the enemy without injuring the enemy by firing Kevlar ropes to bind the enemy unable to move optimally. The researcher used the experimental method to get the results that confirm the causal relationship between the variables designed, research and develop a basic circuit by determining the effective firing range of the Bola wrap, we use the Sharp Gp2y0a710k0f sensor as an effective sensor measuring distance with a maximum range of 550 cm, the distance detected by the Sharp Gp2y0a710k0f sensor. will be processed by Arduino nano as a programming controller whose output will be displayed on the Oled LCD according to the Sharp Gp2y0a710k0f sensor in the form of a light emitting diode (LED) as an indicator, the solenoid will open the trigger with an effective firing range, and laser as a point shot. From the target, the Bola wrap weapon uses 9mm caliber munitions as a Kevlar rope projectile amplifier to bind enemies or rebels, from the results of the research it can open a predetermined lock between a range of 200 cm - 500 cm which is displayed on the Oled LCD, and the green indicator light and the Solenoid are open.
