INTISASISistem rekomendasi merupakan bidang yang dimanfaatkan untuk mengatasi persoalan dalam pencarian informasi yang relevan dari banyaknya kumpulan informasi yang tersedia. Hingga saat ini telah banyak situs web penyedia informasi lowongan kerja, namun pada situs-situs web tersebut masih belum terdapat sistem yang dapat merekomendasikan jenis keterampilan yang sesuai. Sehingga banyak para pencari kerja yang tidak update terhadap jenis keterampilan dibutuhkan di dunia kerja yang terus bertambah seiring perkembangan teknologi. Oleh karena itu, dibuatlah sistem rekomendasi untuk merekomendasikan jenis keterampilan yang sedang tren didunia kerja dan memberikan rekomendasi tempat belajar(pelatihan) untuk memenuhi keterampilan yang disarankan. Sistem rekomendasi yang dikembangkan menggunakan teknik User Based Collaborative Filtering dan Tanimoto Coefficient Similarity. Keluaran yang dihasilkan oleh sistem berupa keterampilan baru dan tempat belajar(pelatihan). Pengujian dilakukan dengan metode Black-Box Testing dan Technology Acceptance Model (TAM). Hasil pengujian menggunakan Black-Box Testing bahwa secara fungsional berjalan dengan baik karena tidak ditemukan adanya error atau bug pada setiap proses pengujian dilakukan. Hasil Pengujian menggunakan Technology Acceptance Model (TAM) sebesar 88.36%. Pengujian hasil rekomendasi sebesar 82% dan secara keseluruhan hasil rekomendasi dapat diterima dengan baik oleh pengguna.Â Kata kunciâ€”Sistem rekomendasi keterampilan, user based, collaborative filtering, tanimoto coefficient similarity, black-box testing, technology acceptance model (TAM)..Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ABSTRACTThe recommendation system is a field that is used to overcome problems in finding relevant information from the large collection of available information. Until now, there have been many websites that provide job vacancy information, but on these websites there is still no system that can recommend the appropriate type of skill. So that many job seekers are not updated on the types of skills needed in the world of work which continues to grow along with technological developments. Therefore, a recommendation system was created to recommend the types of skills that are trending in the world of work and provide recommendations for places to study (training) to meet the recommended skills. The recommendation system developed using User Based Collaborative Filtering and Tanimoto Coefficient Similarity techniques. The output produced by the system is in the form of new skills and a place to learn (training). Testing is carried out using the Black-Box Testing and Technology Acceptance Model (TAM) method. The test results using Black-Box Testing that functionally run well because no errors or bugs were found in each testing process carried out. Test results using the Technology Acceptance Model (TAM) of 88.36%. Testing the results of recommendations by 82% and overall the results of the recommendations can be well received by users.Â Keywordsâ€” Skills recommendation system, user based, collaborative filtering, tanimoto coefficient similarity, black-box testing, technology acceptance model (TAM).

English Muslim merupakan Lembaga Pendidikan Bahasa Inggris. Pihak English Muslim ingin membuka cabang baru atau berpindah lokasi, namun mengalami kesulitan dalam hal menentukan lokasi usaha yang strategis. Menentukan lokasi usaha untuk English Muslim bukan hal yang mudah, dikarenakan apabila lokasi usaha ini tidak terlihat atau tidak terjangkau maka akan sangat sulit untuk berkembang. Berdasarkan pemaparan tersebut dibutuhkannya salah satu metode yang dapat menentukan lokasi usaha yang strategis. Salah satu metode tersebut adalah Data Mining dengan menggunakan algoritma Naïve Bayes Classifier. Data awal yang di gunakan pada data mining yaitu data survei dari lembaga kursus yang bekerja sama dengan English Muslim. Penelitian menyajikan perhitungan Naïve Bayes dalam menentukan lokasi usaha yang strategis, atribut yang digunakan price year, business completeness, target, competitors, position location, wide street, dan public transportation. Metode Naïve Bayes tersebut diimplementasikan dalam sebuah sistem penentu lokasi usaha yang strategis, berbasis web dengan bahasa pemprograman Java dan Framework Zkoss. Hasil penelitian aplikasi ini menunjukan bahwa pihak English Muslim dapat menentukan lokasi usaha stategis atau tidaknya dengan kecepatan waktu yang berjalan cepat, dilihat dari pengujian aplikasi.

This research aims to implement QR code technology in an Android-based futsal field rental system. The development method used is an Android-based software development method (Mobile Apps Development). QR codes are used as a medium for user identification and verification when ordering a futsal field. This system is designed to make it easier for users to make field reservations quickly and efficiently. Users can make orders via the Android application by scanning the QR code available at the futsal field location. The implementation results show that using QR codes can speed up the reservation process and reduce the possibility of data input errors. Apart from that, using this system can also improve the user experience in ordering futsal fields. It is hoped that the implementation of QR codes in this system can increase efficiency and convenience in the overall futsal field ordering process.

Serangan siber berbasis pemindaian jaringan dan eksploitasi sistem menjadi ancaman signifikan bagi keamanan aplikasi web. Alat seperti Nmap dan Metasploit banyak digunakan oleh peretas untuk mengidentifikasi celah keamanan serta mengeksploitasi sistem target. Penelitian ini bertujuan untuk mengevaluasi efektivitas layanan Cloudflare dalam memitigasi serangan reconnaissance dan eksploitasi tersebut. Metode yang digunakan adalah pendekatan eksperimental dengan melakukan simulasi serangan terhadap dua lingkungan server: satu tanpa proteksi Cloudflare dan satu dengan konfigurasi penuh layanan Cloudflare. Serangan dilakukan menggunakan teknik pemindaian port dan service enumeration dari Nmap, serta injeksi payload eksploitasi menggunakan Metasploit Framework. Hasil pengujian menunjukkan bahwa Cloudflare mampu secara signifikan mengurangi keberhasilan pemindaian dan eksploitasi, dengan tingkat deteksi dan pemblokiran mencapai lebih dari 90% terhadap permintaan mencurigakan. Fitur seperti Web Application Firewall (WAF), rate limiting, dan penyembunyian IP server terbukti efektif dalam menghambat proses pengintaian serta serangan berbasis payload otomatis. Penelitian ini menyimpulkan bahwa Cloudflare merupakan solusi mitigasi yang efisien dalam meningkatkan ketahanan sistem web terhadap serangan berbasis Nmap dan Metasploit.

The increasing number of patient visits to hospitals each year poses challenges in providing fast and efficient services, especially during the registration process. Conventional registration systems often cause long queues and patient discomfort. This study aims to design the HealthyQue mobile application as a digital solution for hospital registration based on the Android platform. The application development follows the Design Thinking approach through five stages: empathize, define, ideate, prototype, and test, to deeply explore user needs and behaviors. The results of this process are realized in the form of system modeling using Unified Modeling Language (UML), including use case diagrams, activity diagrams, sequence diagrams, and class diagrams to structurally depict the system's workflow and architecture. This application offers features such as online patient registration, doctor schedule checking, and real-time queue notifications. The implementation of HealthyQue is expected to improve hospital administrative efficiency, reduce patient waiting times, and enhance service quality. The design results demonstrate that the Design Thinking approach effectively produces solutions aligned with user needs, while UML modeling supports the system documentation in a technical and systematic manner.
