Cervical cancer is one of the most common cancers worldwide and is largely caused by Human Papillomavirus (HPV) infection, particularly types 16 and 18. The development of this cancer is influenced by the E6 and E7 oncoproteins, which disrupt the function of p53 and Rb proteins, as well as the involvement of cellular signaling pathways such as PI3K/AKT/mTOR and EGFR. Limitations of conventional therapies, such as resistance and side effects, drive the need for more targeted and selective therapeutic agents. This study aims to analyze the main molecular targets of cervical cancer and the medicinal chemistry approaches used in its therapeutic development. The method involved a review of 12 open access articles using molecular docking, molecular dynamics, QSAR, and network pharmacology approaches. The findings identified two main target groups: viral targets comprising the HPV E6 and E7 oncoproteins, and cellular targets including the PI3K/AKT/mTOR pathway, EGFR, PARP1, CDK1, and VEGFR. Various medicinal chemistry strategies, from structure-based and ligand-based drug design to multi-target network pharmacology approaches, proved effective in identifying potential inhibitor candidates. Bioactive compounds such as quercetin, gossypol, bixin, and rutin demonstrated stable interactions with these targets. However, further experimental validation is needed to support the development of clinically effective and safe therapies.

This study aims to examine the implementation of the Village Financial System (SISKEUDES) information technology by applying the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework and the Technology Acceptance Model (TAM) in Daleman Village, Lawu Village, and Baran Village, Sukoharjo Regency. By adopting a qualitative descriptive approach and triangulation methods, the research establishes that internal control mechanisms under the COSO guidelines are being applied productively. Such compliance is demonstrated through the mandatory cross-verification process conducted by the Financial Officer and Village Secretary, supported by the analytical capabilities of the system’s built-in audit trail. From the TAM perspective, village officials show a high level of technology acceptance, since the system is perceived to provide considerable ease of use and significant benefits in improving the efficiency of financial reporting. Nevertheless, several technical challenges remain, particularly server congestion during peak reporting periods. In addition, there is still a limitation in external transparency, as the dissemination of financial information through digital platforms such as village websites has not been optimally socialized to the community. As a result, many residents continue to rely on conventional information channels such as information boards and village meetings. Therefore, although internal accountability has been well established, improvements in digital infrastructure and communication strategies are necessary to strengthen transparency in village financial management

This study aims to analyze the determinants of success of PT Makmur Susanti Group, a processed food MSME in Tulungagung, East Java, in achieving “Born Global” status by bypassing the traditional incremental internationalization process and penetrating global markets within only 2.5 years. The research employed a qualitative approach using a single case study method. Data were collected through semi-structured in-depth interviews with the owner as the key informant, participatory observation, and documentation, and were analyzed using the Miles, Huberman, and Saldaña interactive model, consisting of data reduction, data display, and conclusion drawing. The findings reveal that the company’s rapid internationalization was supported by three main factors, namely visionary managerial capability reflected in entrepreneurial alertness, continuous product innovation through selective raw material use and flavor localization, and the optimal utilization of digital ecosystems such as B2B platforms and Alibaba. In addition, the study identified a “symbiotic” business model involving export aggregators to serve diaspora niche markets, which challenges the conventional assumption that Born Global firms must independently manage international logistics. Furthermore, the owner’s legal background became a strategic advantage in addressing complex halal regulations and international certification requirements. This research contributes a new perspective on the phenomenon of “non-intentional” Born Global firms and highlights the importance of legal-formal competence for MSMEs, while also providing practical insights for regional MSMEs in integrating local comparative advantages with global competitive standards.

Suspicious urban sound recognition is a critical component of intelligent public safety and urban monitoring systems, enabling the automated identification of anomalous acoustic events such as gunshots, sirens, and other security-sensitive sounds. However, existing deep learning approaches often struggle to simultaneously capture long-range temporal dependencies and global contextual relationships, particularly under noisy and acoustically complex urban conditions. This limitation can reduce reliability in safety-critical scenarios where missed detections carry significant risk. To address these challenges, this study proposes a Multi-Branch Bidirectional Long Short-Term Memory (BiLSTM) framework with Multi-Head Self-Attention (MHSA) for enhanced sequential and contextual feature modeling. Mel-frequency cepstral coefficients (MFCCs) are extracted from a curated subset of the UrbanSound8K dataset, comprising five suspicious sound classes, and used as input to the proposed architecture. The multi-branch design enables complementary temporal representations, while the self-attention mechanism provides lightweight contextual weighting of BiLSTM outputs. Experimental results demonstrate that the proposed model achieves a test accuracy of 95.59%, outperforming conventional Dense and LSTM-based baseline models under identical experimental settings. An ablation study further confirms the contribution of multi-branch integration and attention-based enhancement to overall performance. Class-wise evaluation reveals consistently high recall across all sound categories, particularly for safety-critical classes such as gunshots and sirens. These findings indicate that the proposed framework provides robust and reliable performance, making it suitable for real-time smart city surveillance and public safety applications.

This study aims to formulate an integrated Islamic Religious Education (PAI) learning strategy that synthesizes the acculturation of Islam Nusantara and ecological ethics as a response to the fragmented character of conventional PAI learning which has not yet optimally integrated local cultural values and ecological awareness. This research employs a qualitative library research method with a systematic literature review approach, analyzing 28 primary sources selected from 67 identified literature published between 2019 and 2025. Data were analyzed using Braun and Clarke's thematic analysis through six stages: familiarization, initial coding, theme searching, theme reviewing, theme defining, and report writing. The findings reveal that Islam Nusantara contains three relevant pedagogical principles cultural humility (tawadu' budaya), cosmological inclusivity, and peaceful transformation while Islamic teachings hold rich ecotheological dimensions through the concepts of ecological tauhid, khalifah fi al-ardh, amanah, and rahmatan lil 'alamin. Based on this synthesis, four integrated learning strategies are formulated: Contextual-Cultural Learning, Eco-Thematic Quranic Interpretation, Community-Based Ecological Projects, and Ecological Spiritual Reflection. This study proposes a new conceptual framework termed "PAI Nusantara-Ekologis," which positions students not merely as ritually devout individuals but as responsible stewards (khalifah) of the earth.

This study analyzes visual signs in the Charlie Chaplin animations Safari at The Park and The King in The Ring using Charles Sanders Peirce’s semiotic framework, focusing on icons, indexes, and symbols. Film and animation communicate meaning through visual elements such as gestures, facial expressions, movements, and character interactions, making them rich for semiotic analysis. Using a descriptive qualitative method, the research identified and categorized visual signs in both animations. Results show that icons, which resemble real-world objects, dominate by establishing story settings natural safari environments in one animation and competitive boxing arenas in the other. Indexes reveal cause-and-effect relationships, demonstrating how gestures, expressions, and actions convey danger, fatigue, or emotional shifts. Symbols convey conventional or cultural meanings, such as Charlie Chaplin’s bowler hat and cane representing his comedic identity, a championship belt symbolizing victory, or a rose indicating affection. While both animations use the same types of signs, the intensity and focus vary with the narrative context: Safari at The Park emphasizes situational and natural elements, whereas The King in The Ring highlights competition and emotional reactions. This study confirms that Peirce’s triadic model effectively explains how meaning is constructed in animation through dynamic visual communication.

This study addresses the issue of suboptimal student academic performance, which is frequently linked to the selection of instructional strategies that do not actively engage learners. Learning outcomes represent a multidimensional construct involving knowledge acquisition, attitude development, and skill formation. Therefore, the application of an appropriate learning model is essential to support meaningful learning experiences. This research aims to investigate the impact of implementing a Problem Based Learning (PBL) model supported by audio-visual media on students’ academic achievement. A quantitative approach with a quasi-experimental design was employed. The study involved two groups: an experimental class receiving the PBL intervention and a control class experiencing conventional instruction. Data were collected through pretest and posttest assessments and analyzed using both descriptive and inferential statistical techniques. The findings reveal a statistically significant difference between the two groups, indicated by a significance value below 0.05. This confirms that integrating problem-based strategies with audio-visual support contributes positively to improving students’ learning outcomes. The results highlight the importance of student-centered learning environments in fostering deeper understanding and engagement.

The Qiroati method is an instructional approach to reading the Qur’an that emphasizes direct practice of tartil recitation in accordance with the rules of tajwid. This method is practical, systematic, and implemented gradually, meaning that learners are not allowed to proceed to the next level before achieving fluency at the current stage. One of the main challenges in learning to read and memorize the Qur’an is the limited use of structured teaching methods, as some teachers still rely primarily on personal experience and conventional reading approaches. This condition contributes to students’ lack of fluency in reading and memorizing the Qur’an, as well as decreased learning motivation due to monotonous and less effective instructional practices. This study aims to examine the implementation of the Qiroati method in improving students’ Qur’anic reading ability within the Tahfidzul Qur’an program at SMP Daruttaqwa Full Day School. The findings are expected to provide useful insights for educators and contribute to academic knowledge. This research employs a field research design with a descriptive qualitative approach, focusing on describing the application of the Qiroati method in enhancing students’ reading ability in relation to Qur’an memorization. Data were collected through interviews, tests, and documentation, while data analysis involved data collection, data display, and conclusion drawing. The results indicate that the implementation of the Qiroati method effectively improves students’ ability to read the Qur’an in the Tahfidzul Qur’an program. This is evidenced by the improvement in students’ reading scores compared to their previous performance. In practice, the method involves teachers modeling correct recitation, followed by students reading collectively. Therefore, the Qiroati method not only enhances students’ accuracy in reading the Qur’an but also fosters a more engaging and effective learning environment.

Discretion exercised by election management bodies constitutes an administrative instrument that is functionally necessary to prevent stagnation in electoral processes under conditions of legal vacuum, normative ambiguity, or extraordinary circumstances. However, in practice, discretionary decisions often generate public concern and expose election officials to the risk of criminalization, particularly when such discretion is assessed through a formalistic and result oriented criminal law paradigm. This study aims to analyze the construction of criminal liability of election administrators for the use of discretion in conditions of electoral stagnation, by examining the paradigm shift from the old Indonesian Criminal Code to the new Criminal Code and its implications for criminal law enforcement under the Criminal Procedure Code. This research employs a normative legal method using statutory, conceptual, and case approaches. The findings reveal that the old Criminal Code tended to facilitate policy criminalization by emphasizing formal violations and objective consequences, whereas the new Criminal Code introduces a substantive approach centered on subjective fault, official purpose, and rationality of action. Nevertheless, the lack of synchronization with the Criminal Procedure Code which remains focused on conventional evidentiary standards causes discretionary actions of election administrators to remain legally ambiguous. Therefore, harmonization between substantive criminal law and criminal procedure law, along with a transformation in law enforcement reasoning, is essential to ensure that discretion exercised by election officials is assessed proportionally, contextually, and in line with democratic principles.

Indonesia's increasing economic growth has intensified competition in the business world, particularly in the Indonesian banking sector, from conventional to sharia-compliant. Furthermore, the entry of foreign banks has made business activities in Indonesia increasingly complex. The stock market is a crucial source of funding for companies. Publicly listed companies can increase their funding sources by selling ownership in the capital market. Dividends are the distribution of company earnings to shareholders in the form of cash, assets, or other forms. Dividend policy is a policy for sharing company profits with shareholders, which is announced in the form of dividends and retained earnings for the benefit of company growth. The proportion of dividends distributed to shareholders depends on the company's profitability and dividend policy. The percentage of profits distributed to shareholders in the form of dividends is called the Dividend Payout Ratio.Differences in calculations in determining financial ratios in banking companies are an interesting focus in this study. The study results show quite significant results between financial ratios and managers' decisions in making dividend policy decisions. In the future, the results of this study are expected to be a consideration and reference for investors who want to enter the world of investment, especially in the banking sector.

The rapid development of digital technology has significantly transformed financial transaction systems, including the use of securities. Conventional securities, which traditionally function as instruments of payment, evidence, and transfer of rights, face various challenges such as document forgery, loss, and administrative inefficiency. These conditions have encouraged the digitalization of securities, requiring adjustments within the Indonesian legal framework. This study aims to analyze the transformation of securities from conventional forms to digital formats within the perspective of Indonesian law and to assess the adequacy of existing regulations in addressing such developments. The research employs a normative juridical approach by examining primary legal materials in the form of statutory regulations and secondary legal materials consisting of legal literature and previous studies. The findings indicate that although electronic documents have been legally recognized as valid evidence, there is no specific and comprehensive regulation governing digital securities. Consequently, legal uncertainty remains regarding the transfer of rights, evidentiary strength, and legal protection for holders of digital securities. This study is expected to contribute conceptually to the development of adaptive legal regulations that ensure legal certainty and protection in the context of modern digital transactions.

The problem of urban flooding is a growing issue due to high population density, increasing volumes of plastic waste, and the reduction of water absorption areas. The use of conventional paving blocks, which are impermeable, further exacerbates flooding conditions because they do not allow water to infiltrate into the soil. This study aims to develop an innovative plastic waste-based paving block incorporating rice straw and sugarcane bagasse, along with the integration of phytoremediation concepts as a solution for urban flood mitigation. The method employed was an experimental approach involving the following stages: material preparation, plastic incineration, material mixing, molding, and testing of water absorption capacity and compressive strength. The results showed that paving blocks with a combination of plastic waste, rice straw, and sugarcane bagasse had the highest water absorption rate of 34% and compressive strength of 21 kg/cm², meeting SNI standards. The addition of natural materials containing silica was proven to enhance the material’s porosity and strength. Additionally, the application of phytoremediation using water hyacinth has the potential to improve the quality of water seeping into the soil. Thus, this phytoremediation-based paving block innovation can serve as an effective alternative solution to reduce flood risks while supporting sustainable waste management and environmental stewardship.

The coal mining industry requires accurate stockpile volume measurements for inventory and production reporting. Conventional methods have limitations in accuracy, efficiency, and safety. This study compares the accuracy and efficiency of coal stockpile volume measurements using a Terrestrial Laser Scanner (TLS) Leica MS60 and an Unmanned Aerial Vehicle (UAV) DJI Matrice 4E, validated by the ASTM D6172-98 standard. Conducted on five Run of Mine (ROM) coal stockpiles covering 13,500 m² at PT XYZ, Lahat, South Sumatra, the TLS method used 43 scan positions, while the UAV employed 430 aerial images with specific flight parameters. Data were processed using Leica Infinity, Surpac, and Agisoft Metashape. The results showed volumes of 94,076 m³ (TLS) and 94,965 m³ (UAV), with a difference of 889 m³ (0.95%). Volume deviations ranged from 0.48% to 1.89%, with an average of 1.42%, all within the ASTM tolerance (<2%). Time efficiency analysis revealed that the UAV method required 200 minutes (3.33 hours), saving 63.3% (approximately 6.17 hours) compared to the TLS method (570 minutes). The largest efficiency gain occurred during field data acquisition, with an 85% reduction in time. This study confirms UAV photogrammetry as a valid, accurate, and efficient alternative for coal stockpile volume measurement in mining.

The amalgamation and flotation methods are widely used by miners because the methods are simple, fast and easy. The purpose of this study was aims to test the effectiveness of gold recovery using the amalgamation and flotation methods in conventional gold processing. The research methods used were observation and testing using the amalgamation and flotation methods in conventional gold processing. The effectiveness analysis was carried out by calculating the percentage of gold produced in the amalgamation and flotation processing methods. The test was carried out on 10 samples, each weighing 10 kg. The amalgamation process used a Hg solution, while flotation used a detergent reagent. The total primary gold processing using the amalgamation method was 11.46 grams, while the total primary gold recovery using the flotation method was 12.15 grams. The results of gold processing using the flotation method were higher than those using amalgamation because flotation can separate gold more efficiently from ore containing various impurity minerals. Meanwhile, the amalgamation method, which uses mercury, tends to be less effective and loses some of the gold because it only binds very fine and dispersed gold particles, while flotation can handle ore with lower gold content and larger gold particles.

Heating, Ventilating, and Air Conditioning (HVAC) systems often suffer from significant energy wastage due to their inability to adapt to real-time environmental changes, leading to high operational costs. Although Proportional-Integral-Derivative (PID) controllers are widely used for their simplicity and reliability, they struggle to handle the complex dynamics of modern environments, requiring advanced optimization to enhance efficiency. This study aims to optimize PID controllers by integrating the Queen Honey Bee Migration (QHBM) algorithm to improve HVAC performance, energy efficiency, and adaptability. The research method employs an experimental approach that compares the performance of conventional PID controllers with PID controllers optimized using the QHBM algorithm under dynamic environmental conditions. The results show that the PID-QHBM system significantly outperforms the conventional PID system, achieving a rise time of 0.2649 seconds and a settling time of 1.6874 seconds with an almost negligible steady-state error of 9.4991e-08. Although it experiences a slight overshoot of 16.3810%, the system stabilizes quickly and maintains the target temperature efficiently. In contrast, the conventional PID controller exhibits slower response characteristics, with a rise time of 1.3730 seconds, a settling time of 2.5144 seconds, and a larger steady-state error of 0.0361. This study demonstrates that integrating the QHBM algorithm into PID controllers provides a more effective solution for real-time temperature control, offering substantial improvements in energy efficiency and system performance. The findings contribute to advancing intelligent HVAC control systems that can better adapt to environmental variations while minimizing operational costs.
