Abstract

Condition monitoring and early detection of machine failures are important aspects in industrial systems to improve operational reliability and reduce the risk of unexpected failures. This study aims to analyze the application of the Case-Based Reasoning (CBR) method in condition monitoring and early identification of machine failures by utilizing historical data and operational parameters. The variables used include temperature, vibration, pressure, rotational speed, and load as the main indicators of machine condition. The CBR method is implemented through four main stages, namely retrieve, reuse, revise, and retain. The retrieve stage is carried out by finding the most similar case using attribute-weighted similarity calculations, then the solution is adapted in the reuse stage, adjusted in the revise stage, and stored again in the retain stage to enrich the knowledge base. The calculation results show that the similarity value between the new case and the previous case reaches 0.948 (94.8%), which is obtained from a combination of local similarities of temperature (0.98), vibration (0.90), pressure (0.96), speed (0.99), and load (0.95) variables.

Abstract

Absensi karyawan merupakan aspek penting dalam manajemen sumber daya manusia di setiap organisasi, termasuk di Kantor Komisi Pemilihan Umum (KPU) Kabupaten Serdang Bedagai. Namun, proses absensi yang masih dilakukan secara manual kerap menimbulkan berbagai permasalahan, seperti human error, keterlambatan pencatatan, serta kesulitan dalam melakukan rekapitulasi data kehadiran. Kondisi ini berdampak pada menurunnya efisiensi kerja dan potensi kesalahan administratif yang cukup tinggi. Oleh karena itu, penelitian ini bertujuan untuk merancang dan mengimplementasikan sebuah aplikasi absensi karyawan berbasis website yang mampu mengatasi kendala tersebut, serta meningkatkan efisiensi dan akurasi dalam pencatatan kehadiran. Metode yang digunakan dalam pengembangan aplikasi dibangun menggunakan metode pengembangan sistem SDLC (System Development Life Cycle), yaitu model waterfall yang meliputi beberapa tahapan analisis kebutuhan sistem, perancangan menggunakan Use Case Diagram dan Activity Diagram, serta implementasi dengan menggunakan bahasa pemrograman berbasis web, yaitu PHP, dengan dukungan sistem manajemen basis data MySQL. Hasil dari perancangan ini adalah sebuah sistem absensi digital yang dapat diakses secara online, memungkinkan pencatatan kehadiran secara real-time, serta dilengkapi dengan fitur rekapitulasi otomatis dan laporan kehadiran yang dapat dicetak atau diekspor ke format Excel. Selain itu, sistem membatasi pengisian absensi hanya dari lingkungan kantor, serta memberikan kontrol penuh kepada admin untuk mengelola akun karyawan dan laporan. Dengan hadirnya aplikasi ini, diharapkan proses administrasi kehadiran di lingkungan KPU Kabupaten Serdang Bedagai menjadi lebih efisien, transparan, dan terintegrasi secara digital sesuai dengan perkembangan teknologi informasi saat ini.

Abstract

Serangan Hama burung pipit dan monyet dilahan sawah mengakibatkan kerugian hasil panen yang signifikan. Selama ini, petani masih menggunakan metode tradisional seperti orang-orangan sawah dan bunyi-bunyian manual untuk mengusir hama, namun cara tersebut kurang efektif dalam jangka panjang. Serangan burung pipit mengakibatkan penurunan hasil panen hingga 50% sehingga tim pengabdian mengimplementasikan alat pengusir hama berbasis Internet of Things (IoT) yang dapat dipantau melalui perangkat Android yang telah dibuat. Alat ini menggunakan sensor ultrasonik untuk mendeteksi pergerakan hama yang dapat menjangkau area sawah yang sulit diawasi secara langsung. Pelaksanaan kegiatan meliputi implementasi alat, pelatihan penggunaan alat bagi kelompok tani, serta pendampingan lapangan selama masa uji coba. Hasil kegiatan menunjukkan bahwa penerapan alat IoT ini mampu mengurangi serangan hama hingga 70% dibandingkan metode manual sebelumnya. Selain itu, pemahaman petani terhadap teknologi tepat guna meningkat, terlihat dari kemampuan mereka dalam mengoperasikan serta merawat alat secara mandiri.

Abstract

Program pengabdian masyarakat ini bertujuan mengidentifikasi pemahaman awal, mengimplementasikan pelatihan terstruktur, serta mengukur dampak pengenalan teknik animasi dua dimensi terhadap kompetensi multimedia siswa SMK Darul Ihsan Aceh Besar. Metode deskriptif kualitatif diterapkan dengan melibatkan empat puluh partisipan yang mengikuti pelatihan intensif selama lima puluh jam pada Oktober 2022. Materi difokuskan pada penguasaan teknik shape tweening dan motion tweening menggunakan Macromedia Flash 8 melalui pembelajaran berbasis proyek pembuatan animasi transformasi geometris. Hasil menunjukkan peningkatan signifikan dalam penguasaan teknis dan kreativitas peserta, dibuktikan melalui keberhasilan menyelesaikan karya animasi sederhana dengan pemahaman memadai terhadap prinsip timing, spacing, dan transformasi objek. Antusiasme tinggi dan respons positif dari peserta mengindikasikan efektivitas pendekatan pembelajaran praktis dalam membangun kompetensi animasi. Program ini memberikan kontribusi empiris terhadap pengembangan pendidikan vokasi multimedia di Aceh Besar sekaligus membuka peluang kolaborasi berkelanjutan antara perguruan tinggi dan institusi kejuruan untuk menjawab tuntutan industri kreatif kontemporer.

Abstract

Digital transformation in governance is driving the urgent need for a more modern and structured archive management system. The Aceh National Road Implementation Center (BPJN), especially the PPK 2.5 Subfield, still relies on conventional methods based on physical documents in managing project report archives, causing various problems such as difficulty tracing documents, risk of damage, and operational inefficiencies. Different from previous e-archive research which is generally applied to academic environments or general public services, this study presents the integration of the RAD method with the design of interfaces based on the needs of multi-role users in the context of managing technical reports of infrastructure projects in government agencies, a context that has not been widely studied in previous studies. This research aims to design an effective web-based e-archive information system equipped with an interactive user interface to increase the productivity of internal employees. The system development uses the Rapid Application Development (RAD) approach with the PHP programming language and MySQL database, and is built using the CodeIgniter framework with the Model-View-Controller (MVC) architecture. Data collection was carried out through field observation and structured interviews, while system validation used the black-box testing method. All 15 functional test scenarios were declared successful. A Likert scale user satisfaction evaluation involving three internal respondents showed a satisfaction rate of 86.7%, which falls into the excellent category.  The evaluation includes five aspects, namely ease of navigation, clarity of view, system response, design consistency, and general satisfaction, which are the basis for calculating the percentage. Given the limited number of respondents, further research is recommended to expand the number of samples and apply standard usability instruments such as the System Usability Scale (SUS) to strengthen the validity of the evaluation results. In addition, this study has not included comparative quantitative data before and after the implementation of the system, such as the measurement of document search time or the rate of archive loss in the manual mechanism compared to the new system, so the amount of efficiency improvement cannot be measured verified. System functionality validation also includes black-box testing, without additional testing such as stress testing, performance testing, or security testing, so the strength of the evidence for efficiency improvement claims is still limited and indicative. The developed system contains the features of uploading documents, searching archives, downloading reports, and managing user access rights. Although initial results show positive indications of system functionality and user satisfaction, the strength of the evidence for claims of improved archive management efficiency is still limited given the lack of comparative quantitative data before and after implementation and the new testing scope including black-box testing. The developed system still shows initial feasibility to be implemented gradually within BPJN Aceh, with a more comprehensive follow-up evaluation.
