Abstract

Kelahiran prematur adalah kelahiran yang terjadi sebelum minggu ke 37 atau lebih awal dari hari perkiraan lahir. Berbagai masalah yang dapat ditimbulkan oleh kelahiran prematur. Bayi berat badan lahir rendah (BBLR) adalah bayi baru lahir yang berat badan lahirnya pada saat kelahiran kurang dari 2500 gram. Dahulu neonatus dengan berat badan lahir kurang dari 2500 gram atau sama dengan 2500 gram disebut prematur. Bayi prematur mempunyai resiko kematian yang lebih tinggi dibandingkan dengan bayi yang lahir cukup bulan. Banyak faktor yang mempengaruhi meningkatnya angka kematian bayi prematur. Salah satunya yaitu minimnya pengawasan kondisi tubuh bayi prematur setelah lahir. Pada penelitian ini, dibuat sebuah sistem yang dimplementasikan pada inkubator yaitu sistem monitoring. Sistem monitoring menggunakan bluetooth sebagai media komunikasi untuk monitoring. Untuk monitoring bayi, digunakan load cell untuk mengukur berat bayi, DS18B20 untuk mengukur suhu tubuh bayi, dan pulse sensor untuk mengukur detak jantung bayi.Kata Kunci— Monitoring, suhu, load cell, pulse sensor, bluetooth.

Abstract

This study evaluates the efficacy and security robustness of a Remote Terminal Unit (RTU) data connection protected by a Virtual Private Network (VPN) deployed on the Zyxel USG 2200 router. The aim is to evaluate the effects of IPsec and SSL VPN implementations on network performance, particularly in terms of latency and packet loss, and to assess system resilience against cyberattacks through penetration testing. An experimental methodology was employed, involving the configuration of IPsec/SSL on the Zyxel router and VA modem, conducting packet transmission tests, and performing a security evaluation using Kali Linux tools (Hydra, NMAP, and Metasploit). The results indicate superior network performance, with latency values of 1.8 ms and 5.1 ms, and packet loss rates of 0.14% and 0.81%, signifying that the communication channel is exceptionally reliable and appropriate for real-time RTU applications. Port scanning revealed five open ports (21, 22, 53, 80, 443), but all penetration attempts were futile. Hydra faced failure due to a key-exchange mismatch; NMAP was unable to identify appropriate authentication keys despite numerous attempts, and Metasploit experienced connection issues during exploitation efforts. These findings validate that the established encryption and authentication systems offer sufficient defense against brute-force and fundamental exploitation threats. The research reveals that deploying IPsec and SSL VPN on the Zyxel USG 2200 enhances communication security while maintaining network performance. Future studies should incorporate long-term load testing and more sophisticated, multi-layered attack scenarios to achieve comprehensive security certification.

Abstract

Instalasi listrik tiga fasa merupakan sistem penyaluran tenaga listrik yang menggunakan tiga penghantar fasa (R-S-T) dan satu penghantar netral (opsional), dengan beda sudut fasa 120° antar fasanya. Sistem ini umumnya digunakan untuk beban daya besar, terutama motor listrik 3 fasa yang banyak diaplikasikan di industri, bengkel, dan fasilitas produksi. Kegiatan pelatihan tersebut melibatkan 15 siswa kelas XI Jurusan TITL di SMK Negeri 6 Balikpapan. Bertempat di Laboratorium instalasi 3 fasa Jurusan Rekayasa Elektro Politeknik Negeri Balikpapan, dihadiri 15 siswa SMK Negeri 6 Balikpapan, dan 1 dosen pendamping, kegiatan berlangsung dengan lancar. Dengan didampingi oleh 3 mahasiswa terbaik dari Prodi Teknologi Listrik, pelatihan tersebut berhasil meningkatkan minat siswa siswi kelas XI Prodi TITL untuk melanjutkan studi di Politeknik Negeri Balikpapan. Peningkatan capaian hasil, terukur melalui praktikum langsung dan dievaluasi oleh tim dosen PkM, hasilnya sangat memuaskan. Peserta dibagi menjadi 3 kelompok dan ditugaskan untuk merangkai ulang wiring instalasi 3 fasa dengan beban output motor 3 fasa dengan tambahan pushbutton NO dan NC. Selanjutnya menambahkan IoT berupa aplikasi blynk yang dirancang di hp android, lalu digunakan untuk menjalankan motor 1 fasa secara otomatis.

Abstract

The rapid development of telecommunication technology has driven the demand for fast and stable data access, especially in fourth-generation (4G) networks with Long Term Evolution (LTE) technology. One of the key components in supporting wireless network performance is the antenna. This study discusses the design and testing of a pentagon-shaped microstrip patch antenna with MIMO 8x8 and 8x1 array configurations at a frequency of 1.8 GHz. Simulation results show that the MIMO 8x8 antenna has a VSWR value of 1.18803729 dB and a return loss of -46.4300308 dB, with a gain of 2.995 dBi, while the array antenna has a VSWR of 1.5243619, a return loss of -13.65041 dB, and a gain of 10.4 dBi. The radiation patterns of both are directional. Network performance testing shows that the 8x1 array antenna provides an average download speed of 12.65 Mbps with a jitter of 32.1 ms, while the MIMO 8x8 antenna results in a download speed of 10.187 Mbps with a lower jitter of 32.5 ms. Without any antenna, the download speed only reaches 1.571 Mbps with a jitter of 78.8 ms. Therefore, the use of microstrip antennas is proven to significantly improve the quality of wireless network service.
