Waste remains one of the major environmental issues and a serious challenge in rural communities. The lack of discipline in waste disposal and limited knowledge of the impact of non-biodegradable waste have contributed to declining environmental quality and potential health problems. In Buniwangi Village, Pagelaran Subdistrict, Cianjur Regency, these conditions highlight the need for educational programs that provide practical understanding while fostering community awareness. This community service activity aimed to improve residents’ awareness of waste management through visual education media in the form of information boards displaying the decomposition time of various types of waste, ranging from organic to non-organic materials. The implementation method applied an asset-based community development (ABCD) approach, emphasizing active community participation. The program was carried out in three main stages: preparation, implementation, and evaluation. The preparation stage included location surveys, needs mapping, and obtaining permission from village authorities. The implementation stage involved designing attractive educational boards, installing them at strategic points in the village, and conducting socialization to explain the information provided. The evaluation stage was carried out through direct observation and short interviews to assess the program’s impact on community knowledge and behavior.The results indicated an improvement in residents’ understanding of the differences between biodegradable and non-biodegradable waste. Villagers began to show awareness of reducing single-use plastics and started applying the 3R principles (reduce, reuse, recycle) in daily life. Overall, this program had a positive impact by fostering greater environmental concern and became an initial step toward building a sustainable waste management culture in Buniwangi Village.

Sappan wood (Caesalpinia sappan L.) is known to contain various bioactive compounds such as saponins, tannins, flavonoids, phenols, brazilin, and gallic acid. These compounds play an important role as antioxidants that can ward off free radicals and absorb UVA and UVB radiation that are harmful to the skin. Ultraviolet radiation is known to accelerate premature aging and cause tissue damage, so a topical formulation is needed that can provide protection while maintaining skin health. This study aims to determine the antioxidant activity and sunscreen ability of sappan wood extract in the form of lip balm with varying extract concentrations. Antioxidant activity was evaluated using the DPPH (1,1-Diphenyl-2-Picrylhydrazyl) method, while the Sun Protection Factor (SPF) value was determined by the Mansyur method using UV-Vis spectrophotometry. Sappan wood extract was formulated into four lip balm preparations, namely F0 (control without extract), F1 (5%), F2 (10%), and F3 (15%). Physical tests including homogeneity, pH, spreadability, adhesiveness, and organoleptic were conducted to ensure the quality of the preparation. The results showed that sappanwood extract had an IC50 value of 23.62 ppm which was categorized as very strong antioxidant activity. In the lip balm formulation, the IC50 values ​​obtained were F0 = 246.76 ppm (very weak), F1 = 92.68 ppm (strong), F2 = 78.03 ppm (strong), and F3 = 63.58 ppm (strong). The SPF test showed a protection value of F0 = 2.11 (minimum), F1 = 13.64 (maximum), F2 = 14.25 (maximum), and F3 = 18.28 (ultra). Thus, lip balm made from sappanwood extract has the potential as a cosmetic preparation that not only meets physical criteria, but also provides high antioxidant activity and effective sunscreen protection.

This study investigates the potential of Low-Density Polyethylene (LDPE) plastic waste as a partial substitute for sand in concrete block mixtures, focusing on its effects on compressive strength and water absorption. LDPE is a non-biodegradable plastic waste that poses significant environmental challenges. Its incorporation into construction materials offers a promising solution to reduce pollution while enhancing the performance of building components. The research employed LDPE substitution levels of 10%, 15%, 20%, 25%, and 30% by weight of sand, compared against conventional concrete blocks without LDPE. Experimental results revealed that the highest compressive strength was achieved with a 15% LDPE mixture, reaching 80.762 kg/cm² at 28 days of curing—an increase of approximately 40.8% compared to normal blocks, which recorded 57.359 kg/cm². LDPE additions up to 20% maintained favorable strength characteristics, while higher proportions (25% and 30%) led to a decline in mechanical performance. In terms of water absorption, the inclusion of LDPE demonstrated a decreasing trend, attributed to the hydrophobic nature of plastic, which enhances moisture resistance in the concrete blocks. These findings suggest that a 15% LDPE substitution represents an optimal formulation for producing eco-friendly concrete blocks with improved strength and reduced water absorption. The study highlights the dual benefits of waste management and material innovation, aligning with sustainable development goals. By repurposing plastic waste into construction applications, this approach not only mitigates environmental impact but also contributes to the advancement of green building technologies. Further research is recommended to explore long-term durability, thermal properties, and scalability of LDPE-based concrete products in real-world construction settings.

Waste management remains a serious problem, particularly in rural areas, which generally have relatively low levels of environmental awareness. Inorganic waste such as plastic, glass, and aluminum is a major concern because it takes hundreds of years to decompose naturally. This situation poses potential long-term environmental hazards, including soil and water pollution, and ecosystem disruption. Therefore, effective educational efforts are needed to raise public awareness of waste issues. This community service activity was carried out in Sarah Perlak Village, Sungai Mas District, West Aceh Regency. The focus of the activity was the installation of educational signs containing information about the decomposition time of various types of waste. Implementation methods included direct observation to identify specific problems at the site, informal outreach to local residents, demonstrations related to waste sorting, and the creation and installation of educational signs. The signs were made from wooden planks and decorated with real waste such as plastic bottles, aluminum cans, and used paper, thus providing a tangible visualization to the community. The results of the activity showed that the visual approach through educational signs was able to attract the attention of residents, both children and adults. The information was presented clearly and accompanied by real-life examples, making the message easier to understand and remember. In addition, direct interaction through outreach and demonstrations provided an opportunity for residents to ask questions and share experiences related to waste management. Overall, this educational medium has proven effective in conveying environmental messages, raising awareness, and motivating the community to start sorting and reducing waste at the source. Going forward, this program is planned to be expanded through training in processing waste into useful products, thereby not only reducing pollution but also providing economic benefits to the community.

Museums as cultural preservation institutions have the responsibility to convey information about collections in an informative manner to the public. One of the historical events displayed at the Brawijaya Museum is Operation Trident in 1968. This research aims to design collection labels as an effective communication medium by considering aspects of archive classification, material selection, label design, and information readability. The method used is action research which is carried out through the planning and action stages. The label is designed using Art Paper material with a combination of black-and-white colors and Times New Roman fonts. This research not only emphasizes the aesthetic aspect, but also pays attention to the functional aspect in conveying messages to visitors. The label design process is carried out by paying attention to the suitability between historical content and the form of visual presentation, so that information can be conveyed in a concise, clear, and interesting manner. Effectiveness evaluation was carried out through the EPIC model approach to 105 respondents, including empathy, persuasion, impact, and communication indicators. The results of the study showed that the label was designed to be very effective as a communication medium for museums with high scores on all four indicators. The implication of this research is to improve the visitor experience in understanding the historical value of collections and the efficiency of archive management in the museum environment. In addition, the design of this label can be a reference for other museums in developing information media based on a visual communication approach that is right on target. Thus, the museum serves not only as a repository of artifacts, but also as an interactive and communicative educational center. Furthermore, this research emphasizes the importance of integration between information technology and visual communication strategies in the management of modern museums. The use of professionally designed labels based on the results of empirical evaluation contributes to the improvement of the image of museum institutions in the eyes of the public. It is hoped that this approach can encourage museums to be more innovative in creating participatory learning experiences, especially for the younger generation.

Social campaign posters are one of the visual communication media that has an important role in conveying public messages, shaping perceptions, and encouraging changes in social behavior in society. With visual power, posters can express messages directly, effectively, and emotionally to the audience. This study aims to examine how key visual elements—color, typography, imagery, and layout—affect the emotional response and audience engagement to social campaign messages. A qualitative approach was used by collecting data through visual observation of a number of selected social campaign posters, design analysis, and literature review from relevant literature. The results of the analysis show that each visual element has a significant contribution to the power of the message. Colors, for example, are able to evoke emotional resonance by influencing the mood of the audience, such as the color red that conveys urgency or the color green that represents expectations and the environment. Imagery or illustrations provide the power of imagination and help the audience connect the message with social reality. Proper typography improves readability, emphasizes the main message, and establishes the desired tone of communication. Meanwhile, a well-planned layout creates a visual flow that makes it easier for the audience to understand the message in order. The harmonious interplay between colors, typography, imagery, and layout has been proven to strengthen visual appeal, evoke empathy, and motivate audiences to participate in social campaigns. 

This study examines the development of Islamic civilization during the time of the Prophet Muhammad (peace be upon him) using an approach that rejects the conceptual dichotomy between the Meccan and Medina phases. The title "Meccan Period (622–632 CE)" in this context is not interpreted geographically, but rather as a historical and substantial continuation of Islamic values instilled in Mecca before 622 CE and culminating in the socio-political institutions in Medina after the Hijrah. This study uses a qualitative method with a literature study approach to examine the causal relationship between the spiritual foundations instilled in Mecca and the development of Islamic civilization institutions in Medina. The results of the study indicate that the Meccan period was a phase in the formation of the spiritual and moral character of Muslims through the strengthening of the values of monotheism, patience, justice, and noble character amidst social and political pressures. These values formed a solid ideological basis for the formation of a civilized Islamic society. After the Hijrah to Medina, these values were not only maintained but also systematically institutionalized. This is reflected in several important aspects, such as the drafting of the Medina Charter as the basis of the constitution that guarantees plurality and social justice, the establishment of the Prophet's Mosque as a center of religious and governmental activities, the regulation of the economic system through the prohibition of usury and the obligation of zakat as a form of equitable distribution of wealth, and the development of an educational system that emphasizes the integration of knowledge and manners. Thus, it is concluded that the consolidated Islamic civilization until 632 AD was the result of a development process based on spiritual and moral values that had been intensively instilled since the early phase in Mecca. This study emphasizes the importance of value continuity in the process of social transformation, as well as the relevance of a spiritual approach in the development of an inclusive, just, and sustainable civilization.

The Abbasid dynasty was one of the most influential Islamic caliphates and left a long legacy in the development of world civilization. Established in 750 AD and ending in 1258 AD, the Abbasid period is known as the Golden Age of Islam due to its extraordinary progress in various fields, including politics, economics, and science. This study aims to examine how the Abbasid political and economic policies and the development of science that took place during that period were able to contribute significantly to the progress of global civilization. This study uses a qualitative method with a descriptive-historical approach through the study of relevant literature in the last five years. The results of the study indicate that political stability and a structured bureaucratic system provided a strong foundation for economic growth and intellectual progress. The Abbasid government established a center of knowledge in Baghdad known as Baitul Hikmah (House of Wisdom). Here, scientists from various religious and cultural backgrounds gathered to translate, develop, and disseminate knowledge from Greek, Persian, Indian, and other scientific traditions into the Islamic world. Some of the great figures who emerged during this period included Al-Khwarizmi (mathematics), Ibn Sina (medicine and philosophy), and Jabir Ibn Hayyan (chemistry). Their discoveries and work became the foundation for modern science. However, the glory of the Abbasids slowly declined due to internal conflicts, power struggles, and the weakening of the caliph's authority. The peak of the fall occurred when Baghdad was attacked and destroyed by the Mongols in 1258 AD. However, the intellectual and cultural heritage of the Abbasid dynasty continues to have an important influence on the development of world science and civilization to this day.

Rapid technological developments have penetrated various aspects of human life, including data and information security. Amidst the threat of data leaks and misuse, information protection has become crucial. One solution to maintain data confidentiality is to implement cryptography technology. Cryptography is the study of techniques to secure messages so they cannot be read by unauthorized parties. This process is carried out by encoding the original message (plain text) into an unreadable form (cipher text), which can only be understood by those who possess the key to decrypt it. This study used the Caesar Cipher algorithm, a form of classical cryptography. This algorithm uses a substitution method, where each letter in the message is shifted by a certain amount based on a predetermined key. Caesar Cipher is a symmetric algorithm, meaning the key used for encryption is also used for decryption. The security of this algorithm lies in the secrecy of the key, which is known only to the sender and recipient of the message. This method is relatively simple, but still relevant for securing data with low to medium sensitivity levels. This study used WhatsApp messages as the object to be encrypted using the Caesar Cipher algorithm. The results show that encrypted messages become unintelligible without prior decryption. This demonstrates that the Caesar Cipher can protect messages from unauthorized parties. Therefore, implementing this algorithm can be an initial solution for maintaining data confidentiality in digital communications, especially on platforms vulnerable to eavesdropping or unauthorized access. Its primary benefit is maintaining message integrity and confidentiality to prevent misuse.  

This article discusses the dynamics of Islamic education during the Sultanate of Banten, an Islamic kingdom that developed since the 16th century and became one of the centers of Islamic civilization in the archipelago. Islamic education in Banten not only shapes the Islamic identity of the community, but also strengthens morality, social solidarity, and cultural resilience. Islamic boarding schools are the main pillars of education that integrate the teaching of religious science, character education, and socio-religious practices. The role of pesantren expands, not only as a learning center, but also as a da'wah institution that instills the values of independence, justice, and brotherhood in the midst of a multicultural society. Great scholars such as Sheikh Nawawi al-Bantani and Sheikh Yusuf al-Makassari have an important role in strengthening the scientific network between Banten, the Middle East, and the Islamic world. Their profound works in the fields of jurisprudence, Sufism, and morals had a great influence on the development of Islamic thought in Southeast Asia. The pesantren curriculum that focuses on the yellow book, with the teaching methods of sorogan, bandongan, and wetonan, produces students who are not only knowledgeable, but also disciplined, moral, and sensitive to social problems. The Dutch colonial period brought severe challenges with secular policies and restrictions on Islamic education. However, pesantren still exist as spiritual and intellectual fortresses. This success is supported by the ability of pesantren to develop economic independence and expand scientific networks through the overseas migration of students to various Islamic study centers abroad. Until now, Banten's Islamic education heritage has transformed into a modern Islamic boarding school that is able to combine classical traditions with technology and global insights. This study confirms that traditional Islamic education in Banten has a strategic role in shaping the social, spiritual, and identity structure of the Muslim community, which persists across generations.

Southeast Asia has long held a strategic position in global maritime trade since the pre-Islamic era. Through interactions with Arab, Persian, and Indian merchants, Islam was introduced to the region not through military conquest, but via peaceful and cultural means, particularly through trade and Sufi missionary activities. The Islamization process unfolded gradually, beginning in major port cities such as Samudera Pasai, Malacca, and Gresik, with significant support from local elites. This study employs a qualitative descriptive-analytical approach using library research methods, drawing from historical records, Malay Islamic manuscripts, and recent academic studies. The findings reveal that Islamic civilization in Southeast Asia manifested in the form of Islamic sultanates, traditional Islamic educational institutions (pesantren and pondok), and rich cultural expressions such as arts, literature, and architecture shaped by local aesthetics. This acculturation process gave rise to a moderate, inclusive, and adaptive form of Islam. In the modern era, Islam in this region continues to evolve in response to global challenges through institutional innovation and the contextualization of Islamic values. Therefore, Islam in Southeast Asia is not merely a religious system, but a civilizational force that shapes a distinctive and sustainable regional identity.

Object-Oriented Programming (OOP) is a programming paradigm that emphasizes the use of objects and classes to build modular and maintainable software. One of the fundamental concepts in OOP is polymorphism, which is the ability of objects from different classes to respond to the same method in different ways. This study aims to analyze the effectiveness of the polymorphism concept in directing software design in terms of code structure, development utility, and maintenance efficiency. The research method used is a literature study and program code simulation using a procedural approach compared to an object-oriented approach that applies runtime polymorphism. The results of the analysis show that the use of polymorphism can significantly reduce the number of lines of code, logical structure traffic, and facilitate feature expansion without the need to change existing code. Thus, polymorphism has proven effective in improving readability, reusability, and scalability of software design.

Prayer constitutes the essence of worship in Islam and serves as a profound expression of faith, resilience, and spiritual submission. This study aims to unveil the multifaceted dimensions of the prophets’ prayers in the Qur’an by integrating the adābi ijtimāʾī approach of Tafsir Al-Azhar (Buya Hamka) and the lughāwī approach of Tafsir al-Kashshāf (Mahmud al-Zamakhsharī). Employing a qualitative descriptive design with library research and content analysis (tahlīlī-munaṣābah-semantik), primary data comprised Qur’anic verses featuring prophetic supplications. Analysis focused on etymological, morphological, rhetorical, and socio-cultural aspects, as well as the ethical etiquette (adab) and pedagogical functions embedded in each prayer. Findings reveal that prophets’ prayers encapsulate layers of linguistic eloquence, spiritual resilience, and communal guidance, while divine corrections within certain supplications underscore the pedagogical nature of revelation. This integrative tafsir framework offers a holistic model for incorporating Qur’anic supplications into contemporary character and academic education, fostering both linguistic insight and social relevance

This article aims to examine the development of Islamic education during the Umayyad Dynasty with a focus on two main aspects: how the Islamic education system was formed and the extent of the government's role in supporting it. By using a qualitative-descriptive approach based on historical studies, and including library research. Data collection techniques use various literature both from history books and from articles in national and international journals and conduct data analysis using content analysis. The results show that Islamic education during that period already had a functional structure through halaqah, mosques, and houses of scholars, although it had not been formally institutionalized. On the other hand, the Umayyad Dynasty government played an important role through Arabization policies, the construction of mosque infrastructure, and the creation of political stability that allowed science to develop. These findings underline that education during the Umayyad period grew from the synergy between community initiatives and structural support from the State.

The development of digital technology has brought major changes in the behavior of the millennial and Z generations, including in the religious aspect. This article examines the strategy of internalizing prayer etiquette in the digital era as part of moral education. This study uses a qualitative approach through a literature study of literature on prayer etiquette, the character of the digital generation, and appropriate learning methods. The results of the study indicate that internalization of prayer etiquette among the digital generation must be carried out wisely through the use of digital media, strengthening the role of families and educational institutions, and integrating spiritual values ​​into everyday life. Education on prayer etiquette not only teaches the procedures for worship, but also forms character, such as awareness, solemnity, and discipline. Therefore, a contextual and creative approach is needed so that prayer values ​​can be embedded in the lives of the millennial and Z generations.

The rapid development of digital technology has significantly influenced educational approaches, particularly in Islamic education for digital native generations. This study analyzes the concept of Islamic education in the digital era based on the book Tarbiyah fi Zaman al-Fitan by Sheikh Dr. Ali bin Yahya al-Haddadi and explores its influence on digital native generations. Using a qualitative approach with library research methodology, this study conducts an in-depth analysis of the primary source supplemented by relevant secondary literature including books, scientific journals, and previous research findings. The research integrates Digital Native theory, Social Cognitive theory, and Connectivism to understand the educational challenges faced by digital natives. The findings reveal four main pillars of Islamic education according to al-Haddadi: parental education, gradual education from early age (tarbiyah tadrijiyyah), creed education (aqidah), and social etiquette education (adab). These pillars effectively serve as protective measures against two main fitnah (trials) in the digital era: syahwat (lust) and syubhat (doctrinal confusion). The study demonstrates that classical Islamic educational concepts remain highly relevant for addressing contemporary digital challenges, providing internal firewall mechanisms, strengthening parental role modeling, and promoting adaptive collaborative learning. This research contributes to the development of Islamic educational frameworks that integrate classical spiritual values with modern digital literacy requirements.

In recent years, education has placed greater emphasis on academic achievement, often overlooking the importance of character and ethical development in students. However, instilling the value of adab (proper manners) before knowledge is essential as a foundational aspect of the learning process. Adab encompasses attitudes such as respect for teachers, honesty, responsibility, and politeness, which contribute to forming ethical individuals. This study aims to explore the significance of adab values in education as an effort to cultivate students' character and ethics from an early age. The research uses a literature review method by analyzing various sources from Islamic education and character education theories. The findings reveal that the integration of adab values can be achieved through teacher role modeling, fostering positive habits within the school environment, and embedding these values into learning materials. When consistently applied, these approaches create a conducive learning atmosphere and develop students who are not only intellectually capable but also morally upright. The study implies that a balanced approach to education, which emphasizes both knowledge and adab, should be instilled early in both school and family settings

This study aims to examine the values of etiquette (adab) of students towards teachers as viewed by three prominent Islamic scholars: Imam Ghazali, Imam Az-Zarnuji, and Imam An-Nawawi. Etiquette towards teachers is considered a fundamental aspect of the teacher-student relationship in Islamic education, which emphasizes not only academic achievement but also moral values and ethics. Imam Ghazali, in his works, stresses the importance of respect, humility, and sincere intention in learning. Imam Az-Zarnuji, in his book Ta'lim al-Muta'allim, offers practical guidelines on student etiquette, including how to speak and behave appropriately towards teachers. Meanwhile, Hadrotus Syaikh Hasyim Asy’ari, in Adabul Alim Wal Muta'allim, advises students to always maintain proper manners with their teachers as a form of respect for both the knowledge and its possessor. This research employs a qualitative approach with content analysis to explore and compare the views of these three scholars regarding student-teacher etiquette. The findings reveal that, despite differences in expression and detail, all three scholars agree on the significance of etiquette as a foundational element in the learning process. These values of etiquette include politeness, exemplarity, respect, and loyalty in the pursuit of knowledge. This study is expected to contribute to the development of Islamic education, particularly in strengthening the harmonious relationship between students and teachers based on the etiquette values espoused by these scholars.

An open pit exploitation activity will become less effective and cause production to not run well, resulting in the failure to meet production targets at PT. Indominco Mandiri. Therefore, to achieve production targets and obtain more optimal results, we need to plan the Design Pit Limit. The purpose of this research is to optimize the pit, find the BESR value, and compare the differences between two methods. The Lerch Grossman 2D algorithm method is believed to be able to determine the optimal pit boundary quite quickly, while the Minescape with its triangle method can calculate some unreadable sides quite accurately. The Lerch Grossman method with its economic blocks indicates that an elevation of 72 mdpl is the outer boundary of the pit that has the potential to generate a profit of $20,194,836.59, with the best consideration being a Stripping Ratio of 1:21.08. With that lower limit, an optimal pit design was created using minescape software, resulting in a coal reserve value of 1,581,870.42 tons with a profit of $14,590,646.75, which is larger and with a smaller SR of 1:19.06.
