Secure image transmission is increasingly vital in the digital era, especially against emerging quantum threats. This study proposes a hybrid image encryption scheme that integrates Quantum Key Distribution (QKD) using the BB84 protocol with a combination of 7-dimensional (7D) and 2-dimensional (2D) hyperchaotic systems to achieve robust security. The BB84 protocol facilitates quantum-assisted key exchange, ensuring resistance to eavesdropping, while the hyperchaotic systems provide high entropy and complex randomness, utilized in a layered permutation-substitution encryption framework. The initial seeds for chaotic sequences are derived using a SHA-512 hash of both the input image and quantum-generated key, ensuring uniqueness and sensitivity. Experimental validation was conducted using several benchmark images. The information entropy values of the ciphered images reached up to 7.9993, indicating excellent randomness. Differential analysis showed high resistance to small perturbations, with NPCR exceeding 99.61% and UACI averaging around 33.47%, which meet standard security thresholds. Histogram and chi-square tests confirmed the uniform pixel distribution, with chi-square values below 280, satisfying the randomness criterion for 8-bit images. Furthermore, correlation coefficients of adjacent pixels dropped to near zero, evidencing effective decorrelation. The encryption scheme also demonstrated robustness to data loss, as shown by the successful decryption of partially corrupted cipher images. Robustness testing under partial data loss (200×200-pixel blocks) also demonstrated visual recoverability and algorithm resilience. Overall, the proposed BB84-assisted dual-hyperchaotic encryption scheme offers a secure and computationally effective solution for protecting sensitive image data, making it suitable for post-quantum secure communications.

The enzymes laccase (Lac), manganese peroxidase (MnP), and lignin peroxidase (LiP) are ligninolytic enzyme groups that have a crucial role in degrading lignin compounds. These complex components are abundant in plant biomass. This research aims to isolate and characterize microorganisms producing the enzymes Lac, MnP, and LiP from leaf litter, rhizosphere soil, and sediment in the Gunung Lumut Protected Forest (GLPF) and Sungai Wain Protected Forest (SWPF), East Kalimantan. The bacterial and fungal isolates obtained were cultured on NA and PDA media enriched with 0.05% guaiacol as a substrate. Initial selection was carried out based on the colony growth rate and the formation of a brownish discoloration zone, which indicates ligninolytic enzyme activity. The superior isolates were then tested for extracellular enzyme activity quantitatively using a UV-Vis spectrophotometer. Among the bacterial isolates, the highest Lac activity is isolated GLS 5.1.2 (173.44 U L-1); the highest MnP activity is isolated GLS 5.3 (177.41 U L-1); and the highest LiP activity is isolated GLS 5.1.2 (1034.05 U L-1). In the group of fungi, isolate SS2 was detected with the highest Lac activity (20.66 U L-1), MnP activity (333.75 U L-1), and LiP activity (2516.13 U L-1). Biodiversity sources in the Gunung Lumut Protected Forest (GLPF) and Sungai Wain Protected Forest (SWPF), East Kalimantan have the potential to produce microbial isolates with unique enzymatic characteristics that have never been reported before. The resulting microbial isolate can be used as a bioactivator in composting organic waste to produce high-quality organic fertilizer.

This community service activity aims to increase the awareness of the community around the IAIN Ambon campus regarding the importance of plastic waste management and maintaining environmental cleanliness. Through the Participatory Action Research (PAR) method, students of the Islamic Criminal Law Study Program at the Faculty of Sharia IAIN Ambon acted as facilitators in the socialization and implementation of plastic waste recycling activities. This activity included education on the negative impacts of plastic waste, waste sorting practices, recycled product creation, and waste cleanup actions. The results showed positive changes in community behavior towards the environment and improved students' skills in applying the amar ma'ruf nahi munkar principle. This activity not only had a tangible social impact but also strengthened the application of Islamic values in the context of environmental preservation.

MSMEs play a key role in the national economy, especially in increasing economic growth and creating new jobs. However, in the digital era, MSMEs face major problems, such as low levels of digital literacy, limited access to the internet, and fierce competition with large companies that have used technology before. This study examines the variables that influence the sustainability of MSMEs amidst digital challenges and finds methods that can be used so that MSMEs can survive and grow. The research method was carried out through surveys and direct interviews with MSME actors at Pasar Pagi Setia Budi, Medan, North Sumatra. The results of the study showed that most MSME actors did not utilize digital platforms for marketing and transactions, which resulted in decreased income. To increase competitiveness, MSMEs need to improve their digital knowledge, adopt online marketing strategies, and optimize the use of e-commerce and social media. Support from the government, financial institutions, and technology companies is also very important. In the increasingly competitive digital era, by implementing the right digitalization strategy, MSMEs can improve operational efficiency, expand market reach, and maintain the sustainability of their business.

Digital transformation in the Industry 4.0 era significantly impacts the effectiveness of human resource management (HRM). This article discusses the impact of digital transformation on HRM, focusing on changing roles, developing digital skills, and utilizing technology for more effective and efficient decision-making. In the past, HRM focused on administrative aspects, but now, there is a demand to develop digital skills for employees in response to modern workplace dynamics. Digital competencies are becoming essential and contributing to increased productivity and organizational competitiveness. This transformation requires a more adaptive competency-based approach to ensure employees have skills relevant to technological developments. HR management facilitates this adaptation through appropriate training and technology implementation in data-driven decision-making processes. By doing so, organizations can respond to challenges and take advantage of new opportunities in the digital era. The World Economic Forum (2020) emphasizes that digital skills, such as technological understanding, data analysis, and digital device proficiency, are now an essential foundation for competitiveness in the modern job market. With the paradigm shift from an administrative function to a strategic role, innovative leadership is required for HRM to support organizational success in the face of Industry 4.0.
