Abstract

Industri telekomunikasi berkembang sangat pesat dan perusahaan telekomunikasi terus melakukan berbagai inovasi untuk mendukung persaingan bisnis yang benar-benar sengit dan semakin sulit mendapatkan pelanggan. Persaingan ini menghasilkan churn pelanggan. Churn pelanggan yang tinggi adalah salah satu tingkat kegagalan perusahaan, oleh karena itu churn harus dikurangi. Algoritma Random Forest dipilih karena memiliki kemampuan untuk mengklasifikasikan data yang tidak lengkap dan dapat menangani data sampel yang besar. Tujuan khusus dari penelitian ini adalah untuk membandingkan kinerja algoritma Random Forest dengan optimasi menggunakan teknik boosting (XGBoost dan AdaBoost). Pada penelitian menggunakan Upsampled untuk mengatasi data yang tidak seimbang dan metode interquartile range dalam mengatasi pencilan. Hasil penelitian ini menujjukkan bahwa optimasi algoritma Random Forest menggunakan boosting AdaBoost menghasilkan kinerja yang paling optimal dengan hasil akurasi (99.13%), presisi (98.31%), recall (100%) dan f1-score (99.15%).

Abstract

Marriage is an important moment in life that is influenced not only by emotional aspects, but also by socioeconomic factors. The socioeconomic status of the prospective groom can affect the harmony of the household that will be built. This study aims to classify the socioeconomic status of prospective grooms using the Modified K-Nearest Neighbor (MKNN) algorithm and evaluate its performance through accuracy, precision, and recall measurements. The dataset used consists of 200 data points on prospective grooms obtained from the BKKBN (National Family Planning Agency) of Bondowoso District, with attributes including occupation, source of income, and income value. The classification process involves data pre-processing, Euclidean distance calculation, validation of training data, weighted voting, and K-fold Cross Validation. The test results showed that MKNN was able to provide good classification performance, with the highest accuracy of 88%, precision of 91.60%, and recall of 88% in a specific K-Fold scenario. This study shows that the MKNN algorithm is effective in classifying the socioeconomic status of prospective grooms and can be used as a reference for further research.

Abstract

Efektivitas manajemen kerumunan menjadi aspek penting dalam pelaksanaan ibadah haji dan umrah, mengingat mobilitas jemaah yang sangat tinggi pada waktu dan lokasi tertentu. Kepadatan yang tidak terkendali berpotensi menimbulkan risiko keselamatan dan mengganggu kelancaran ibadah. Penelitian ini mengusulkan pendekatan klasifikasi tingkat kepadatan kerumunan (crowd density) dengan memanfaatkan data operasional yang merepresentasikan dinamika pergerakan, perilaku individu, dan kondisi lingkungan. Dataset yang digunakan terdiri dari 10.000 entri dengan 29 fitur. Algoritma Extreme Gradient Boosting (XGBoost) dipilih karena kemampuannya mengolah data kompleks dan heterogen. Hasil pengujian menunjukkan akurasi 98.7%, precision 99%, recall 99%, dan f1-score 99% untuk kategori rendah, sedang, dan tinggi, baik pada macro maupun weighted average. Temuan ini menunjukkan bahwa model yang dikembangkan memiliki tingkat akurasi dan keandalan yang tinggi dalam memprediksi kepadatan kerumunan.

Abstract

Corona Virus Disease (Covid-19) began to enter Indonesia in March 2020. The spread of this virus was massive in July with the highest case on July 15, 2021. So far, cases have started to decline because the discipline of health protocols has begun to be applied, and most Indonesians have received the Covid-19 vaccine. The growth of Covid-19 had a major impact and became an obstacle to Indonesia's economic growth, especially the Micro and Small Industry (MSI). According to the Asian Development Bank (ADB) there are 50% of Small and Medium Industries went bankrupt due to Covid-19 because turnover has decreased by 40% - 70%. In the Covid-19 pandemic situation, Product Branding can be offered to MSI as one of the solutions to problems to achieve economic resilience. The Community Partnership Program is expected to be able to contribute to solving the problems faced by IMK in Sorong, namely "competitor constraints" and "marketing constraints". In relation to competitor constraints and marketing constraints, MSI is expected to be able to market products easily and be able to compete. For this reason, product branding insight is needed. In this case, MSI actors need to be equipped with product branding insights, so that they can sell their products easily, precisely in booking, easy to recognize their products, and customer loyalty. For this reason, product branding skills need to be socialized to improve the quality of MSI Actors' Human Resources. Based on evaluation results, in general the initial knowledge related to product branding is good, with the lowest score for the pretest 54 and the highest score being 70. Meanwhile, in the posttest score there was a significant increase in the value, with the lowest score being 73 and the highest score reaching 95.

Abstract

Kegiatan Pengabdian kepada Masyarakat ini dilatarbelakangi oleh urgensi kebutuhan peningkatan keamanan fasilitas di SMA Muhammadiyah 2 Wuluhan yang hingga kini masih menggunakan kunci konvensional. Sistem pengamanan manual memiliki berbagai kelemahan, seperti risiko kehilangan dan duplikasi kunci, ketiadaan pencatatan aktivitas akses, serta minimnya efisiensi dalam pengelolaan kunci antar pengguna. Kondisi ini berpotensi mengganggu kelancaran proses pendidikan dan menimbulkan risiko keamanan pada ruang-ruang penting seperti laboratorium, ruang server, dan ruang arsip. Di sisi lain, sekolah juga belum menerapkan teknologi digital modern seperti Internet of Things (IoT), sehingga terdapat kesenjangan antara pembelajaran kejuruan yang diajarkan dengan praktik teknologi nyata di lapangan. Tujuan utama kegiatan ini adalah mengimplementasikan sistem keamanan pintu otomatis berbasis IoT dan RFID sebagai solusi modern, aman, dan efisien untuk meningkatkan keamanan ruangan, mempermudah akses pengguna, serta memperkuat literasi digital bagi guru dan siswa. Kegiatan ini juga mendukung Renstra Pengabdian Unmuh Jember pada bidang Smart Village, khususnya aspek smart education dan penerapan IPTEKS di masyarakat. Metode pelaksanaan menggunakan pendekatan teknis, edukatif, dan partisipatif, melalui lima tahapan yaitu: analisis kebutuhan dan survei lokasi; perancangan serta pengembangan sistem; implementasi perangkat di sekolah mitra; pelatihan dan pendampingan bagi guru serta siswa; dan evaluasi serta tindak lanjut. Prototipe sistem dikembangkan menggunakan NodeMCU/ESP32, modul RFID RC522, servo motor kunci, dashboard web, serta integrasi Wi-Fi untuk pemantauan real-time. Luaran kegiatan mencakup luaran wajib pengabdian dan luaran kegiatan pengabdian. Luaran wajib yakni jurnal terakreditasi minimal sinta 6 dan publikasi media massa berupa artikel berita online. Adapun luaran kegiatan pengabdian, yakni: (1) terpasangnya sistem pintu otomatis IoT–RFID yang berfungsi penuh; (2) dashboard digital untuk manajemen akses; (3) peningkatan kompetensi digital guru dan siswa; (4) dokumentasi pelaksanaan PkM; serta (5) model sistem keamanan berbasis IoT yang dapat direplikasi sebagai bagian dari implementasi smart school dan smart village.
