Wayfinding adalah proses mencari dan menentukan arah untuk mencapai tujuan dalam suatu lingkungan. Menurut Passini (1984), proses wayfinding meliputi tiga tahap utama: pengambilan keputusan, pelaksanaan keputusan, dan pemrosesan informasi. Proses ini melibatkan berbagai perilaku dan strategi navigasi yang berbeda tergantung perbedaan individual dan keadaan lingkungan. Studi ini mengkaji strategi navigasi berdasarkan klasifikasi perilaku wayfinding Barker (2019), yang mengelompokkan perilaku ke dalam tiga kategori utama: sosial, semantik, dan spasial. Berdasarkan Barker (2019) dan Dalton dkk. (2019) perilaku sosial melibatkan penggunaan informasi dari interaksi atau tindakan orang lain. Perilaku semantik menggunakan simbol dan petunjuk. Sedangkan perilaku spasial bergantung pada elemen fisik dan model kognitif di lingkungan. Melalui pencarian di berbagai database ilmiah, ditemukan 40 artikel yang diterbitkan antara tahun 1980 hingga 2025, dengan persentase penelitian terbaru dalam 10 tahun terakhir sekitar 60% yang dianalisis dalam kajian ini. Hasil dari tinjauan literatur ini menemukan bahwa individu dari berbagai kondisi dan latar belakang memiliki strategi navigasi yang berbeda, ada yang menggunakan perilaku sosial, perilaku semantik, atau perilaku spasial, bahkan ditemukan pula perilaku kombinasi. Pemahaman yang mendalam terhadap variasi perilaku ini memberikan implikasi penting dalam perancangan elemen arsitektur interior maupun sistem navigasi yang inklusif dan responsif terhadap kebutuhan seluruh pengguna.

Therefore, this community service program is designed to introduce da'wah as an effective two-way communication process in addressing these dynamics. The main objective of this program is to improve digital da'wah literacy and foster motivation and practical skills in creatively conveying Islamic messages through social media platforms. This community service activity is carried out through a series of activities, including outreach, interactive discussions, and practical simulations for creating digital da'wah content. The outreach is intended to provide a basic understanding of da'wah in a digital context. Interactive discussions allow participants to share views and understand how da'wah can be carried out effectively in cyberspace. Meanwhile, the da'wah content creation practice provides participants with the opportunity to directly engage in creating da'wah messages that can be disseminated through social media. Evaluation of the activity is carried out through pre- and post-tests held before and after the program implementation. The analysis results showed an increase in participants' understanding of more than 35% across all tested indicators. The highest increase (56.3%) was recorded in their understanding of the importance of two-way communication in da'wah. Previously, many participants considered da'wah to be an activity limited to religious leaders. However, after participating in this program, they began to understand that da'wah is a task for every individual, and can be carried out through media closely related to their daily lives. Overall, this program succeeded in increasing knowledge, critical awareness, and enthusiasm for contextual da'wah among Gen Z.

This study aims to understand how learning about rainbows can improve elementary school students' understanding of basic science concepts, particularly regarding the refraction of light and the color spectrum. The concept of rainbows is an important part of Natural Science (IPA) lessons because it involves optical phenomena that can be directly observed and related to students' daily experiences. In this study, the method used is a literature study, namely by collecting, reviewing, and analyzing various relevant library sources, such as scientific articles, textbooks, and educational journals that discuss the topic of science learning and the rainbow phenomenon. The results of this study indicate that learning about rainbows can be done through various interactive and fun approaches, such as through practical experiments using prisms, water droplets, or other simple media that can demonstrate the process of refraction of white light into a color spectrum. In addition, the use of visual media such as images, animated videos, and digital simulations has also proven effective in helping students understand the process of rainbow formation more concretely. Creative activities such as drawing rainbows, making color models, or role-playing as light and water droplets can also increase active student participation and make learning more enjoyable. This study also emphasizes the importance of integrating rainbow learning into the elementary school science curriculum systematically and contextually. Rainbow materials not only introduce scientific concepts in a fun way, but also develop critical thinking, observation, and experimental skills in children. With the right approach, this learning can foster students' interest in science from an early age. Therefore, the results of this study are expected to contribute positively to the development of more effective, creative, and developmentally appropriate science learning methods for elementary school students.

Bullying is a recurring issue and has become a widespread concern, particularly among children and adolescents in school environments. Schools, which should ideally be safe spaces for learning, building friendships, and experiencing personal growth, often turn into places of fear and psychological distress for some students. This is largely due to the frequent violation of human rights (HR) that often goes unaddressed or is underestimated. Bullying can take many forms, including verbal, psychological, physical abuse, and increasingly, cyberbullying. Each of these forms can cause serious harm not only to the victims—who may suffer from emotional and mental trauma—but also to the perpetrators, who may experience long-term psychological consequences and develop deviant or aggressive behavior patterns. In Indonesia, bullying remains a significant issue and a major concern in the education sector. Nearly every school has faced incidents of bullying in one form or another. Cyberbullying, in particular, is harder to monitor and control since it often occurs outside the school’s jurisdiction and is carried out through social media platforms. Efforts to tackle bullying must go beyond merely protecting and supporting the victims. A comprehensive approach is necessary, one that also focuses on preventive education. Students, teachers, and parents must be consistently educated on the negative impacts of bullying, the importance of empathy, and a deeper understanding of human rights. Moreover, strict and clear sanctions must be imposed on perpetrators as a form of legal enforcement and deterrence. With a holistic strategy that involves all elements of the school and the wider community, it is hoped that educational institutions can truly become safe, inclusive, and supportive environments. Such conditions are essential for fostering not only academic growth but also the psychological well-being and character development of the nation's children.

Tempoyak is a traditional Indonesian fermented food made from the flesh of durian (Durio zibethinus Murr.), which undergoes spontaneous fermentation driven by indigenous microorganisms. The fermentation process generally occurs under anaerobic conditions and is primarily dominated by lactic acid bacteria (LAB), including species such as Lactobacillus, Leuconostoc, and Pediococcus. These bacteria play a crucial role in modifying the physicochemical properties of the product, including a significant reduction in pH, an increase in the concentration of organic acids, and the formation of volatile compounds responsible for tempoyak’s distinctive aroma and overall flavor complexity. In addition to enhancing its unique sensory profile, the fermentation process also extends the shelf life and introduces probiotic potential to the final product. This study aims to observe and analyze the microbiological and chemical aspects of tempoyak fermentation and to evaluate its potential as a local functional food with health-promoting properties. Laboratory tests and microbial analyses confirmed that the fermentation process not only retains essential nutrients but also promotes the growth of beneficial bacteria, provided the production conditions are hygienically maintained at all stages. The study emphasizes the importance of controlled fermentation techniques to ensure product safety and consistent quality. Furthermore, the findings reveal that tempoyak could serve as a promising probiotic-rich food that supports digestive health, contributing to the diversification of traditional Indonesian fermented foods. With its appealing flavor, cultural value, growing consumer interest, and potential health benefits, tempoyak holds significant promise for future development and commercialization, particularly in the field of functional food innovation rooted in indigenous culinary practices.

Photogrammetry is a technique for measuring and modeling three-dimensional objects by utilizing digital imagery from various perspectives. In the context of reverse engineering, this technique serves to duplicate, reconstruct, and analyze the dimensions of physical objects with a high degree of accuracy. The main advantage of photogrammetry lies in its ability to capture the details of the shape and texture of objects without the need for physical contact. However, the quality of photogrammetry scan results is greatly influenced by a number of technical factors, especially lighting and camera sensor sensitivity (ISO) settings. Variations in these two parameters can cause deviations or dimensional deviations in the resulting 3D model. This study aims to quantitatively evaluate the influence of lighting intensity and camera ISO setting on dimensional deviation in photogrammetry scan results. The research method used is experimental, where the dimensions of the scanned object are compared to the original dimensions using precision measuring instruments. The results showed that both the lighting level and the ISO setting had a significant influence on the accuracy level of the 3D model. The ideal lighting intensity range was found to be in the range of 125–150 lux, where shadows and light reflections could be minimized. Meanwhile, the use of low ISO (around 200) is able to produce cleaner image textures and minimize noise, resulting in smaller dimensional deviations. Additionally, the interaction between moderate lighting and low ISO is proven to provide the best scanning accuracy. This combination is able to maintain a balance between image quality and surface detail of the object. These findings not only provide practical recommendations regarding the regulation of scanning conditions, but can also serve as a guideline for industry practitioners and academics in improving the quality of reverse engineering results. With a proper understanding of lighting and ISO variables, the photogrammetry process can be optimized to produce more accurate and efficient 3D models.

Photogrammetry is a widely used technique in reverse engineering that utilizes photographs taken from multiple angles to capture the geometric structure and surface textures of physical objects. This method has gained popularity due to its cost-effectiveness and time efficiency compared to more expensive alternatives such as laser scanning. However, one of the primary limitations of photogrammetry is its susceptibility to dimensional deviations that can affect the accuracy of the resulting 3D model. Among the influential parameters, the number of photos taken and the camera’s shutter speed play a crucial role in determining the level of geometric precision. This study aims to analyze the effect of the number of photos and shutter speed on dimensional deviation in 3D reconstruction results. It also seeks to determine the optimal combination of these parameters to enhance model accuracy in reverse engineering applications. The research method used is an experimental approach, in which variations of photo quantity and shutter speed are applied during image capture. The resulting photographs are processed into a 3D model using Computer-Aided Design (CAD) software and compared with the actual dimensions of the object under study. The findings reveal that both the number of photos and shutter speed significantly influence dimensional accuracy, both individually and interactively. The best results were obtained using a combination of 48 photos with a shutter speed of 0.020 seconds, yielding the smallest deviation of 7.6 mm. In contrast, a combination of 36 photos with the same shutter speed produced the highest deviation at 10.6 mm. ANOVA analysis yielded a p-value < 0.05 and an R² value of 94.21%, confirming the importance of selecting appropriate imaging parameters for accurate photogrammetry outcomes.
