Abstract

The rapid development of information and communication technology has made it an essential part of modern life. Among its many applications, the transmission of video data has become increasingly common, but ensuring its confidentiality and integrity remains a major challenge. Video messages, particularly those containing personal or sensitive information, are vulnerable to interception and unauthorized access when transmitted over public networks. To address this issue, cryptographic methods are employed to transform the original video file (plaintext) into an encrypted form (cipher text), which can only be decrypted with the correct key. Previous studies highlight that while RSA offers a relatively simple encryption mechanism, it is often considered insufficient as a standalone approach. Therefore, this study investigates the combined implementation of RSA and ElGamal algorithms to enhance video file security by leveraging the strengths of both techniques. The experimental results demonstrate that the integration of RSA and ElGamal algorithms can successfully encrypt and decrypt video files, ensuring data confidentiality. Encrypted videos cannot be accessed without the appropriate private key, which safeguards sensitive content from unauthorized parties. Furthermore, RSA is found to be simpler to apply, while ElGamal provides stronger security based on the discrete logarithm problem. Overall, the proposed system effectively maintains both the confidentiality and integrity of video files, thereby improving the security of multimedia data transmission.

Abstract

West Nusa Tenggara Province faces serious waste management problems. Bilok Petung Village produces around 3 tonnes of waste per day, most of which ends up in the landfill. A zero waste approach using BSF (Black Soldier Fly) could be a solution. The aim of KKN activities in Bilok Petung Village is to explore the process of cultivating BSF (Black Soldier Fly) magots to support the implementation of zero waste. Activity methods include providing BSF cultivation facilities, collecting organic waste, hatching BSF eggs, maintaining BSF, harvesting eggs, processing maggots, and packaging products. The results of the activity show that BSF cultivation is able to process village organic waste into pupae and organic fertilizer with economic value. Pupae can be used as a source of animal protein and organic fertilizer can increase soil fertility. Thus, BSF cultivation has the potential to support the implementation of zero waste in Bilok Petung Village in a sustainable manner.

Abstract

This study assessed climate classification, hydrological conditions, and agricultural vulnerabilities in Pangkalpinang City, Bangka Belitung Province, Indonesia, using a 65-year (1959-2024) daily meteorological dataset. Climate classification revealed a dominant Af (Tropical Rainforest) type by the Köppen-Geiger method (occurring in 56 out of 66 years) with high precision (0.89-1.0) and a C1'As (perhumid mesothermal) classification predominating according to Thornthwaite (64 out of 66 years). Trend analysis showed a likely not significant temperature increase (approximately +0.02°C/year) and shifting precipitation patterns, with mean annual rainfall at 2289.84 mm and an annual precipitation concentration index (PCI) of 8.924, indicating a moderately irregular rainfall distribution. Hydrological analysis showed an average potential evapotranspiration (PET) of 0.284 mm, a soil moisture content of 99.751 mm, an average surface runoff of 4.577 mm, and 51 annual flood risk events, exhibiting a humid regime. Mean crop water requirement (CWR) was 4.857 relative units, and we observed a strong positive correlation (r=0.969) between the water requirement satisfaction index (WRSI) and crop water needs. The model validation exhibited a root mean square error (RMSE) between 0.1-0.5 and showed a stable Thornthwaite classification even with perturbations and the time series data analysis revealed the variability of parameters and a shift in temperature around the year 2000. These results emphasize the urgent need for localized climate adaptation strategies in Pangkalpinang.

Abstract

Nature-based tourism is increasingly popular with the public, especially after the COVID-19 pandemic, because it is considered safer, healthier, and closer to nature. One popular form of nature tourism activity is camping. Gayo Camping Ceria, as a nature tourism business in Takengon, Central Aceh, provides tent and camping equipment rental services at affordable prices. However, in its operations, the reservation process and rental management are still carried out manually via WhatsApp and social media, which causes various obstacles such as late confirmations, recording errors, difficulty monitoring stock, and the absence of a centralized documentation system. To address these challenges, this study aims to design and implement a web-based camping reservation system that can automate the entire booking and rental process. The system development methodology uses the Waterfall model, which includes the stages of needs analysis, system design, implementation, testing, and evaluation. The implementation results show that the system successfully meets all functional and non- functional user requirements. The results of the system testing using the black-box testing method indicate that all features run well according to the designed specifications and scenarios. Every process flow, from booking to payment verification, can be executed smoothly. This system has been proven to improve operational efficiency, minimize recording errors, and provide convenience and transparency for both users and administrators. This system not only improves the operational efficiency of Gayo Camping Ceria but also provides a better digital experience for customers. Furthermore, this system has the potential to be adopted by other MSMEs in the nature tourism sector that face similar challenges in managing reservations and rentals. Thus, this research makes a real contribution to the application of information technology to strengthen the digital-based local tourism sector to support sustainable digital transformation.

Abstract

Permasalahan limbah organik di Sukabumi memerlukan peran berbagai pihak, terutama bidang pendidikan. Guru yang memiliki kesadaran keberlanjutan yang kuat dapat merencanakan proyek pembelajaran tentang limbah yang integratif dan holistik. Membekali guru dengan kesadaran keberlanjutan menjadi salah satu upaya mengurai permasalah tersebut. Tujuan dari kegiatan pengabdian pada masyarakat adalah meningkatkan kesadaran keberlanjutan guru terhadap permasalahan pengelolaan limbah organik. Strategi yang dipilih adalah memberikan pelatihan pengelolaan limbah dengan memperhatikan kondisi lingkungan, sosial, dan ekonomi, serta pelatihan tentang design thinking untuk memastikan bahwa inovasi, ide, dan solusi yang dibuat berorientasi pada nilai keberlanjutan. Kegiatan mencakup dua fase, yaitu: pelatihan pengelolaan limbah organik dan design thinking serta kegiatan pengembangan studi kasus permasalahan limbah di sekolah. Kegiatan ini berpengaruh signifikan terhadap 3 dimensi kesadaran keberlanjutan; pengetahuan, sikap, dan perilaku guru dalam mencapai tujuan pembagunan berkelanjutan. Tidak ada perbedaan kesadaran keberlanjutan berdasarkan jenis kelamin, usia, jenjang pendidikan, dan keikutsertaan PPG. Artinya, kesadaran keberlanjutan guru tidak dipengaruhi oleh faktor formal, melainkan hal lain seperti pengalaman personal, interaksi sosial, atau pelatihan. Program pengabdian masyarakat membawa dampak positif dalam peningkatan kesadaran keberlanjutan guru sehingga diharapkan mereka dapat mengembangkan projek yang relevan untuk siswa sebagai kontribusi bidang pendidikan dalam penyelesaian masalah limbah organik di Sukabumi.
