Perbandingan K-Means dan K-Medoids Untuk Clustering Lagu Setipe di Spotify Berdasarkan Karakteristik Audio
Pertumbuhan layanan streaming musik seperti Spotify menghadirkan kebutuhan akan sistem pengelompokan lagu yang mampu meningkatkan pengalaman pengguna melalui rekomendasi yang lebih akurat. Untuk meningkatkan pengalaman pengguna, diperlukan sistem pengelompokan lagu berdasarkan kemiripan fitur audio seperti danceability, energy, acousticness, instrumentalness, liveness, speechiness, dan valence. Penelitian ini membandingkan dua algoritma clustering, yaitu K-Means dan K-Medoids, dalam mengelompokkan lagu-lagu Spotify berdasarkan fitur audio tersebut. Algoritma K-Means dikenal efisien dalam komputasi, sementara K-Medoids lebih robust terhadap outlier. Evaluasi dilakukan menggunakan Davies-Bouldin Index (DBI) untuk mengukur kualitas pemisahan antar-kluster. Hasil penelitian menunjukkan bahwa K-Means memberikan hasil terbaik pada k = 3 dengan DBI 0,857, sedangkan K-Medoids memberikan hasil terbaik pada k = 9 dengan DBI 0,844. Meskipun K-Medoids sedikit lebih baik dalam hal kualitas klaster, K-Means lebih unggul dalam efisiensi waktu komputasi. Penelitian ini memberikan wawasan penting mengenai efektivitas kedua algoritma dalam sistem rekomendasi musik berbasis clustering dan dapat memperkaya literatur tentang pengelompokan lagu di platform streaming<!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves/> <w:TrackFormatting/> <w:PunctuationKerning/> <w:ValidateAgainstSchemas/>

Rancang Bangun Sistem Informasi Pengelolaan Dan Pemesanan Vendor Irsada Event Grup Berbasis Website Menggunakan Model Prototype
The development of information technology has increased the need for digitalization in services for event organizers and vendors. Irsada Event Group, a provider of event equipment in Lamongan, previously relied on a manual system, which often caused problems such as unstructured data recording, risk of data loss, and delays in service. This study aims to develop a web-based information system for vendor management and ordering to improve operational efficiency. The system was developed using the prototype model, allowing direct collaboration with users during the design and testing stages. Laravel 11 was used as the framework, supported by a PostgreSQL database. The system offers core features such as login, registration, product ordering, payment confirmation, product management, and customer reviews. Evaluation was conducted using Black Box Testing and the System Usability Scale (SUS), resulting in 77%, indicating that the system is in the “good” category. The system supports Irsada Event Group deliver faster services and simplify digital data management.

Desain Sistem Pemantauan Dan Peringatan Dini Motor Pompa Jockey 15 kW
Reliable fire protection depends on a jockey pump that keeps system pressure stable at all times. At a facility in East Kalimantan, a 15 kW induction motor drives the jockey pump, and the team currently monitors it only through scheduled preventive maintenance. In practice, this approach struggles to detect sudden faults such as current surges, overheating, or excessive vibration. This study develops a motor condition monitoring system based on sensors and SCADA to continuously track temperature, current, and vibration. The system combines a current transformer (CT), an RTD PT100 temperature sensor, and an IFM VKV022 vibration sensor, all connected to a PLC for data processing and automatic alarm activation. The SCADA interface displays real-time data and alerts, allowing operators to respond quickly and make informed decisions. The proposed system supports early fault detection, improves the reliability of the fire protection system, reduces the risk of unexpected shutdowns, and helps prevent costly motor damage. The study also compares the accuracy of the automated monitoring system with the existing manual method. Keywords: jockey pump, condition monitoring system, temperature sensor, current sensor, vibration sensor, PLC, SCADA, early warning system

Perbandingan LLM pada OpenAI untuk Mengevaluasi Kinerja Pegawai di PT Javan Cipta Solusi
. Evaluating the performance of the best employees in a company is a common problem faced by the human resources division. Assessing subjectively and comprehensively is a challenge that must be overcome in building sustainable business growth. For organizations that are already able to manage employee assignment data in a structured and systematic form, this can be done by processing quantitative data obtained from the task management system. In this study, a large language model-based approach is proposed to identify the best employees based on assignment data for one year. A comparison was made of six versions of LLM on OpenAI to measure employee performance based on a predetermined prompting design. As a result, 50% of respondents considered that the criteria proposed by GPT4o-mini were more appropriate to their needs, and 60% of respondents considered that the employee ranking results produced by GPT-4 were more relevant to the reality.
Pendeteksi Cerdas Salinitas Air Tambak Budidaya Gracilaria di Desa Devisa Sidoarjo Berbasis IoT
Masyarakat dusun Tanjungsari, Desa Kupang, Kecamatan, Jabon Kabupaten Sidoarjo awalnya berprofesi sebagai petambak ikan, petambak udang, pencari ikan, buruh tambak dan buruh pabrik. Sejak tahun 1998 sebanyak 105 KK beralih menjadi budidaya rumput laut. Perubahan profesi berdampak besar sebab penghasilan tidak saja pemilik tambak, buruh tambakpun meningkat sehingga mendapat julukan kampung budidaya gracilaria. Bahkan Dusun Tanjungsari tanggal 31 Mei 2023 ditetapkan sebagai Desa Devisa provinsi Jawa Timur dengan komoditas eksport rumput laut Gracilaria. Namun disetiap tahunnya pada saat musim kemarau panen menurun, hasil panen tertinggi pada bulan Agustus sebesar 2.590 Kg dan terendah bulan Oktober 375 Kg. dan bulan Nopember hanya 250 Kg. Kesenjangan panen gracilaria dipengaruhi oleh faktor suhu dan akibat tingginya salinitas air tambak. Sebagai petambak tradisional untuk mengetahui salinitas cukup merasakan air (mencicip) dengan memasukan tangan kedalam air tambak kemudian dirasakan kedalam mulut. Karena sudah menjadi kebiasaan terkadang terlambat mendeteksi, sehingga air menjadi “letih” yang berdampak pertumbuhan gracilaria terhambat bahkan bisa mati. Peneliti mengusulkan pembuatan Sistem deteksi cerdas tingkat salinitas air secara real time dengan memanfaatkan Internet of Things (IoT) yaitu sebuah pengindera yang ditempatkan di tambak. Setiap saat informasi salinitas air tambak, bahkan apabila pada ambang batas akan muncul peringatan yang dikirim ke smarphone disertai visual grafik batas aman. IoT yang digunakan pada penelitian ini adalah IoT LoRa dan nodeMCU esp8266. Pemantauan tingkat salinitas air tambak menggunakan Sensor Total Dissolved Solid (TDS). Data pembacaan sensor TDS diolah Artificial Intelligence oleh sebuah Microcontroller Arduino Uno. LoRa Transmitter akan mengirimkan datanya ke LoRa Receiver. Setelah data diterima di receiver data dikirimkan melalui Node MCUesp8266 ke aplikasi Blynk yang ada di perangkat smartphone. Luaran penelitian adalah artikel ilmiah terindeks Sinta 5, aplikasi Android cerdas, tugas akhir mahasiswa dan HKI.

ANALISIS SENTIMEN KEPUASAN PENGGUNA APLIKASI MOBILE BANKING BANK ABC MENGGUNAKAN ALGORITMA K-NEAREST NEIGHBOR
Aplikasi mobile banking kini menjadi layanan penting dalam mendukung aktivitas transaksi digital. Untuk mengetahui tingkat kepuasan pengguna, analisis sentimen terhadap ulasan pengguna dapat memberikan informasi yang berharga bagi pengembangan aplikasi. Penelitian ini bertujuan untuk mengklasifikasikan sentimen ulasan pengguna aplikasi mobile banking Bank ABC dengan menggunakan metode K-Nearest Neighbor (KNN). Data sebanyak 1000 ulasan dikumpulkan dari Google Play Store dan selanjutnya melalui tahap pre-processing, yang meliputi cleaning, case folding, tokenizing, stopword removal, normalisasi, dan stemming. Setelah itu, pembobotan kata menggunakan metode TF-IDF digunakan untuk mengubah teks menjadi fitur numerik yang dapat diproses oleh model. Proses klasifikasi dilakukan menggunakan algoritma KNN, sedangkan evaluasi performa dilakukan melalui confusion matrix pada tiga skenario jumlah data, yaitu 250, 500, dan 1000 data. Hasil evaluasi menunjukkan bahwa model memperoleh akurasi sebesar 91% pada 250 data, 88% pada 500 data, dan 89% pada 1000 data, dengan rata-rata akurasi sebesar 87,5%. Temuan ini menunjukkan bahwa metode KNN cukup efektif dalam mengolah dan mengklasifikasikan ulasan pengguna aplikasi mobile banking. Sistem yang dibangun juga dilengkapi antarmuka berbasis web yang memungkinkan pengguna melakukan analisis sentimen dan melihat hasil evaluasi secara interaktif.
