Abstract

Intrusion Detection Systems (IDS) are crucial in maintaining network security and safeguarding sensitive information against external and internal threats. This study proposes a novel approach by utilizing a Pigeon-Inspired Algorithm optimized with the Hyperbolic Tangent Function (Tanh) function to enhance the performance of IDS in threat detection specifically tailored for Internet of Things (IoT) environments. We aim to create a more robust solution for optimizing intrusion detection systems by integrating the efficient and effective Tanh function into the Pigeon-Inspired Algorithm. The proposed method is evaluated on three widely-used datasets in the field of IDS: NSL-KDD, CICIDS2017, and CSE-CIC-IDS2018. Experimental results demonstrate that integrating the Tanh function into the Pigeon-Inspired Algorithm significantly improves the performance of the intrusion detection system. Our method achieves higher accuracy, True Positive Rate (TPR), and F1-score while reducing the False Positive Rate (FPR) compared to traditional Pigeon-Inspired Algorithms and several other optimization algorithms. The Pigeon-Inspired Algorithm optimized with the Tanh function offers an efficient and effective solution for enhancing intrusion detection system performance, specifically in Internet of Things environments. This method holds great potential for application in diverse network environments, bolstering information security and safeguarding systems from evolving cybersecurity threats. By extending the applicability and effectiveness of the Pigeon-Inspired Algorithm optimized with the Tanh function, researchers can contribute to developing more comprehensive and robust security solutions, addressing the ever-evolving landscape of IoT-based cybersecurity threats.

Abstract

The ship is one of sea transport that is widely used by the community particularly wholived in the Islands for example Bengkalis.Bengkalis Regency, which has a layout is verystrategic because it is directly adjacent to the Strait of Malacca until passed by theinternational shipping lanes.Logging current ship passengers still are manual that istyped using a typewriter and delivered straight to the Immigration Office.Thereforecreated an application web-based ship passengers logging by using MySQL as thedatabase that runs on a xampp server so it makes it easy to ship party in merekappassengers and immigration data to view and check out their report data accuratelypassengers. The design method used in this study is UML which consists of use caseand activity diagrams.

Abstract

Literasi merupakan suatu kebutuhan terutama bagi dunia pendidikan termasuk SMKN 2 Bengkalis. Kegiatan literasi di SMKN 2 Bengkalis mengandalkan koleksi referensi di Perpustakaan dan ketersediaan bahan pembelajaran yang dirujuk oleh Guru secara individu. Terdapat dua hal utama yang diselesaikan oleh tim pengabdian yaitu penerapan aplikasi perpustakaan digital dan media pembelajaran daring melalui e-learning. Keadaan perpustakaan di SMKN 2 Bengkalis adalah belum tersedianya aplikasi perpustakaan, akses referensi di perpustakaan terbatas sesuai jam layanan, dan koleksi referensi dalam bentuk hardcopy serta media pembelajaran yang belum tersistem untuk kebutuhan secara daring. Tahapan pelaksanaan kegiatan pengabdian dimulai dengan menyelesaikan media pembalajaran secara daring dan dilanjutkan penerapan aplikasi perpustakaan secara bertahap. Luaran dari kegiatan pengabdian ini adalah terdaftar HKI, publikasi artikel pengabdian pada jurnal, ekspos kegiatan pengabdian di media massa onine, dan video dokumentasi kegiatan

Abstract

Peningkatan system keamanan di lingkungan sekolah dapat dilakukan dengan cara menerapkan smart cctv. Smart CCTV adalah teknologi kamera pengawas yang dilengkapi dengan sistem pengolahan data dan kecerdasan buatan. Dengan teknologi ini, kamera pengawas dapat mendeteksi dan mengidentifikasi objek atau perilaku yang mencurigakan. Penerapan Smart CCTV di lingkungan sekolah dapat dipasang di beberapa titik strategis seperti pintu gerbang, koridor, ruang kelas, dan area parkir. Selain itu, Smart CCTV juga dapat diintegrasikan dengan sistem alarm dan notifikasi otomatis sehingga petugas keamanan dapat segera merespon kejadian yang mencurigakan. Keamanan di lingkungan sekolah merupakan hal yang sangat penting untuk menjaga keselamatan para siswa, guru, dan karyawan. Dalam penerapannya, Smart CCTV dapat memberikan rasa aman dan nyaman bagi siswa, guru, dan karyawan di dalam lingkungan sekolah. Selain itu, Smart CCTV juga dapat membantu pihak sekolah dalam menangani dan mengidentifikasi pelaku kejahatan yang terjadi di lingkungan sekolah

Abstract

Stunting masih menjadi permasalahan kesehatan serius di Indonesia, khususnya di wilayah kerja Poskesdes desa Penampi, kabupaten Bengkalis, provinsi Riau. Hal ini diakibatkan kurangnya pemahaman gizi masyarakat dan keterbatasan tenaga ahli di tingkat desa. Prevalensi stunting di Bengkalis berada pada tingkat 12,%. Hal ini mengalami penurunan dari sebelumnya yang berada pada tingkat 17,9%. Menjawab tantangan tersebut dan membantu pemerintah menurunkan tingkat stunting, maka dilaksanakan kegiatan pengabdian kepada masyarakat berupa penerapan aplikasi konsultasi gizi berbasis digital yang mampu membantu petugas kesehatan dan masyarakat dalam menilai status gizi, diagnosa awal stunting serta memberikan rekomendasi asupan yang tepat, khususnya bagi ibu hamil dan ibu balita. Melalui pelatihan dan pendampingan kader kesehatan serta tenaga medis, program ini tidak hanya meningkatkan kapasitas layanan gizi berbasis teknologi informasi tetapi juga mempercepat upaya pencegahan stunting sejak dini, sekaligus mendorong kesadaran masyarakat akan pentingnya pemenuhan gizi keluarga sebagai wujud nyata sinergi perguruan tinggi dan fasilitas kesehatan dalam penerapan IPTEK untuk solusi permasalahan lokal.

Abstract

This study developed a Certainty Factor (CF)–based expert system to support nutrition consultation and stunting prevention in coastal settings using Bengkalis Regency as a case study. A design science approach was employed to analyze local service constraints, acquire expert knowledge, formalize a rule base, implement an offline-first prototype (mobile client and admin dashboard), and evaluate its performance. Knowledge was elicited from nutritionists, midwives, and community health workers and encoded as IF–THEN rules with expert confidence weights; Evidence (anthropometry, infection history, infant and young child feeding, sanitation, and socioeconomic factors) was mapped to CF values ​​and combined to yield risk scores and categories with explainable rule traces. Functional testing showed all user-story scenarios passed as expected, while initial expert validation and usability checks indicated the prototype provided rapid and standardized assessments suitable for first-line services. The results suggest the CF approach is feasible for coastal contexts with limited connectivity and can accelerate early screening and referrals. Future work will expand the local knowledge base, integrate electronic records, and conduct wider field trials to measure effectiveness at scale
