Abstract

Kondisi saat ini, untuk mendapatkan informasi apa saja, dimana saja dan kapan saja,  asalkan tersedia jaringan internet maka akan sangat mudah mengakses informasi yang kita butuhkan, informasi atau data sekarang ini sumbernya  bukan cuma lewat buku, surat kabar atau yang lainnya yang berupa fisik, melainkan lewat ponsel pintar maupun laptop, namun adanya berbagai kemudahan yang tersedia dibarengi juga dengan dampaknya tidak hanya dari segi positif saja, tapi dari segi negatif pun ada. Contohnya mudah bocornya informasiinformasi penting ke orang yang tidak berkepentingan  yaitu oknum yang secara sengaja mengincar informasi tersebut untuk di selewengkan untuk kepentingan dan tujuan tertentu yang tentu saja merugikan kita sebagai pemilik data, misalkan kata sandi (password) dan nomor PIN.  Hal ini tentu saja menjadi sesuatu yang patut diwaspadai apabila informasi yang dikirimkan merupakan informasi yang bersifat rahasia. Cara mengantisipasinya yaitu dengan cara tidak mudah memberikan informasi apapun kepada siapaun terlebih bila sumbernya tidak jelas, dan meningkatkan kepahaman akan pengetahuan tentang  keamanan data.  Untuk mengamankan data salah satunya dapat dilakukan dengan teknik steganografi, yaitu teknik untuk menyembunyikan keberadaan pesan kedalam sebuah media dengan suatu cara sehingga tidak ada seorang pun yang mengetahui atau menyadari sebenarnya ada suatu pesan rahasia yang hanya diketahui si pengirim dan si penerima. pada steganografi, data yang telah disandikan dapat disembunyikan sehingga pihak ketiga tidak mengetahui keberadaannya. Dengan cara ini maka kita tidak perlu khawatir lagi apabila mengirimkan pesan apapun terlebih bila pesan itu bersifat rahasia ke siapapun dan dalam keadaan aman.

Abstract

Voting is the most important part of choosing leaders in an organization or institution, especially for those of us who use a democratic system. The election of organizational leaders in Darunnajah is still carried out conventionally, elections still use paper to select organizational leaders which is carried out by recording and counting the name or picture of one of the candidates. Creating the Darunnajah Vote System in the form of a web application for the election of organizational leaders in the Darunnajah environment can speed up the voting process. The web application is built using PHP and MySQL with features of user management, class management, candidate management, and E-Voting. This study aims to build an e-voting system that is expected to provide voting results quickly, and accurately and can be monitored in real-time during the implementation of the leader election. This system development method uses a web application-based SDLC Waterfall model. Testing using the black box method, every feature contained in the Darunnajah Vote System application, namely the Admin Login feature, User Login, User Voting, and User Data Processing features runs normally and functions properly.

Abstract

Pesantren as a traditional Islamic educational institution faces challenges in navigating the digital era. Artificial Intelligence (AI) offers significant opportunities to enhance learning effectiveness, administrative systems, and educational management in pesantren. This article examines how AI can be adapted in pesantren education, covering implementation, benefits, and challenges. Using a qualitative approach and literature review, this study finds that AI can support curriculum management, personalize learning, and improve access to broader educational resources. However, AI adaptation also faces obstacles such as infrastructure limitations, human resources, and ethical considerations in applying technology within the pesantren environment. Therefore, an appropriate AI implementation strategy must be designed to align with pesantren values without eliminating its traditional characteristics.

Abstract

Hearing loss is a condition in which a person's ability to hear is disrupted. Symptoms of hearing loss include unclear or even inaudible sounds, difficulty communicating, and the risk of disrupting a person's activities. The purpose of the activity is to provide knowledge about hearing loss and early prevention related to hearing problems in children/toddlers. The activity was carried out on May 2, 2025 in Bobo Village, Jailolo District, West Halmahera Regency, targeting 14 mothers who have toddlers. The results of the activity showed that children responded to sounds from both their parents and their surroundings. A child's ability to respond to sounds in the surrounding environment is an important indicator in sensory and language development. A good response to sound indicates that the child's hearing and attention are developing normally.

Abstract

Eye health is an important aspect of life that often gets less attention, especially among children and adolescents. In today's digital era, the use of electronic devices such as mobile phones, tablets, and computers has become an inseparable part of daily activities. The purpose of this activity is to increase awareness and knowledge about the importance of maintaining eye health from an early age. The counseling activity was carried out at the Faculty of Health Sciences which was attended by 15 students. A pre-test was given before the counseling took place, then continued with providing counseling about eye health using PPT media and continued with the provision of a post-test questionnaire. There was an increase in participant knowledge where the average pre-test score was 8.67 and after that it increased to 8.80. It is hoped that with this activity, participants can apply healthy habits in their daily lives.

Abstract

Providing water to meet community needs is a crucial agenda for ensuring basic needs. Despite relatively abundant water availability, communities often struggle to access clean water. The Tosa Village community faces serious water quality issues. The purpose of this activity is to increase public knowledge and awareness, and provide practical solutions for community self-reliance regarding the importance of clean water access. The activity took the form of training and field practice in making simple water filters. Participants included 25 community representatives and PBL II students. Through education, training, and active involvement in making simple water filters from local materials, the community not only gained affordable technical solutions but also raised awareness of the importance of maintaining water quality. This approach strengthens self-reliance, accelerates healthy behavior changes, and directly contributes to the achievement of Sustainable Development Goals (SDG 6). This community-based initiative can serve as an effective model for addressing the clean water crisis in an inclusive and sustainable manner.

Abstract

Diabetes mellitus is a non-communicable disease whose prevalence continues to increase globally, primarily due to unhealthy lifestyles. A healthy lifestyle, which includes a balanced diet, regular physical activity, stress management, and adequate sleep, plays a crucial role in preventing diabetes mellitus. This community service programme aims to increase public understanding of the importance of a healthy lifestyle as a preventative measure for diabetes mellitus. The activity, conducted in Tosa Village, targeted women from the Family Welfare Movement (PKK) through lectures, discussions, and Q&A sessions. The results showed an increase in the average pre- and post-test scores, from 5.39 to 12.79. It is hoped that this health education programme will help the community change unhealthy behaviors to adopt healthy ones in their daily lives to avoid diabetes mellitus and other diseases.
