Abstract

In today's digital era, server security is a top priority for many organizations. Intrusion Detection Systems (IDS) such as Fail2ban, have proven effective in protecting servers from threats by monitoring logs and blocking suspicious IP addresses. This paper discusses the implementation of Fail2ban integrated with Telegram notifications, how it works, testing, and results showing improvements in detecting and responding to attacks. Server ssh brute force attacks pose considerable risks to web servers and have potentially severe consequences. Implementing strong preventive measures, continuous monitoring, and leveraging Telegram notifications for real-time alerts significantly improved the organization’s security posture. These combined efforts ensure robust and responsive detection of brute force attacks. Fail2ban was able to quickly discover the IP address from which the attacker performed the brute force attack and took preventive action by blocking the attacker's Ip for 3 failed login attempts within a specified time limit of 3600 s.

Abstract

Perencanaan intensitas pencahayaan alami dan buatan yang efektif di ruang-ruang gedung, terutama ruang kelas dan ruang administrasi, sangat penting untuk memastikan kenyamanan visual serta efisiensi energi. Pencahayaan yang optimal mendukung kualitas pembelajaran dan mengurangi ketergantungan pada pencahayaan buatan yang boros energi. Penelitian ini bertujuan menganalisis perencanaan intensitas pencahayaan di lantai 1 Gedung Fakultas Teknik Universitas Darul 'Ulum Jombang menggunakan perangkat lunak Dialux serta mengidentifikasi faktor yang mempengaruhi distribusi pencahayaan di berbagai ruang. Data yang digunakan meliputi floor plan, hasil simulasi pencahayaan dari Dialux, dan pengukuran menggunakan lux meter. Hasil penelitian menunjukkan sebagian besar ruang di lantai 1 Gedung Fakultas Teknik memiliki pencahayaan alami yang kurang memadai. Penelitian ini menunjukan bahwa Ruang Wadek 1 memiliki intensitas pencahayaan alami hanya 1,8 lux, jauh di bawah standar SNI 300 lux. Sebaliknya, Ruang Kelas memiliki 9,2 lux, meskipun standar untuk ruang kelas adalah 350 lux. Simulasi menunjukkan pencahayaan alami di Mini Hall dan Ruang Arsip cukup baik, namun masih perlu perbaikan. Penambahan lampu LED Philips CoreLine Downlight gen5 DN142B 20S PSU-E/4000K WR 19-watt meningkatkan pencahayaan menjadi 429 lux di Ruang Wadek 1 dan 376 lux di Ruang Kelas, memenuhi standar SNI. Penelitian ini menyarankan perbaikan desain arsitektur dan integrasi pencahayaan alami dan buatan yang lebih efisien untuk meningkatkan kenyamanan visual serta mengurangi konsumsi energi.

Abstract

Penelitian ini berfokus pada desain robot line follower untuk memindahkan barang dengan dukungan teknologi Internet of Things (IoT). Tujuan utama penelitian adalah menghasilkan rancangan konseptual yang dapat meningkatkan efisiensi serta efektivitas proses pemindahan barang, terutama pada lingkungan industri, pergudangan, maupun skala pendidikan. Robot dirancang untuk mengikuti jalur tertentu secara otomatis menggunakan sensor cahaya, dengan rancangan sistem kendali berbasis mikrokontroler Arduino Uno. Integrasi IoT dalam desain ini menawarkan kemungkinan pemantauan dan pengendalian secara real-time melalui perangkat berbasis internet, sehingga memungkinkan fleksibilitas operasional dan penghematan sumber daya manusia. Metodologi yang digunakan mencakup studi literatur, analisis kebutuhan sistem, perancangan perangkat keras, penyusunan blok diagram kontrol, serta rancangan perangkat lunak dasar. Hasil kajian konseptual menunjukkan bahwa sistem ini berpotensi bekerja secara stabil, menjaga akurasi lintasan, serta menyelesaikan pemindahan barang dengan lebih efisien dibandingkan cara manual. Penelitian ini masih berada pada tahap desain dan belum mencakup implementasi fisik. Namun demikian, rancangan yang dihasilkan dapat menjadi dasar yang kuat untuk penelitian lebih lanjut, termasuk uji coba eksperimental, integrasi sensor tambahan, serta penerapan pada sistem logistik cerdas di masa depan.

Abstract

Obat-obatan adalah salah satu produk yang sangat penting dalam kehidupan manusia. Oleh karena itu, penyimpanan obat harus dilakukan dengan baik agar kualitasnya tetap terjaga. Salah satu faktor yang penting untuk diperhatikan dalam penyimpanan obat adalah suhu. Suhu yang terlalu tinggi atau rendah dapat menyebabkan obat rusak. Untuk menjaga suhu ruang penyimpanan obat agar tetap stabil, diperlukan sistem pemantauan suhu yang dapat bekerja secara otomatis. Sistem pemantauan suhu ini dapat menggunakan mikrokontroler sebagai pengendalinya. Dalam penelitian ini, telah dirancang sistem pemantauan suhu otomatis untuk ruang penyimpanan obat dengan menggunakan mikrokontroler ESP8266. Sistem ini menggunakan sensor DHT22 untuk mendeteksi suhu ruang penyimpanan obat. Jika suhu ruang penyimpanan obat mencapai 25 derajat celcius, maka kipas DC akan menyala secara otomatis. Sebaliknya, jika suhu ruang penyimpanan obat dibawah 25 derajat celcius, maka kipas DC akan mati secara otomatis. Hasil pengujian sistem pemantauan suhu menunjukkan bahwa sistem ini dapat bekerja dengan baik serta suhu ruang penyimpanan obat dapat dijaga agar tetap stabil.

Abstract

This study introduces the design and evaluation of an automatic roof drive prototype aimed at optimizing tomato cultivation. Developed to address the challenges of erratic weather, the system seeks to enhance the efficiency of tomato farming. The prototype integrates a weather sensor, microcontroller, and roof drive mechanism, allowing it to operate automatically based on real-time environmental conditions. Effectiveness was assessed through field trials measuring key growth parameters such as plant height, fruit number, and fruit quality. Results indicate that the automatic roof drive system significantly improves both the productivity and quality of tomato crops. Additionally, the system effectively mitigates losses due to extreme weather conditions, including heavy rain and excessive heat. These findings highlight the potential of automated roof drive technology to support more efficient and sustainable agriculture. Future work will focus on refining the system for broader applications and integrating advanced technologies such as IoT and machine learning for further optimization.

Abstract

Oyster mushrooms grow optimally at 24-27°C and 80-95% relative humidity. Environmental conditioning through manual spraying water in the mushroom barn in the morning and evening is considered less effective and requires high effort. The application of technology in mushroom cultivation can help control temperature and humidity automatically. This study aims to design an automatic control system to regulate temperature and humidity in oyster mushroom farms. The research was conducted at an altitude of 125 meters above sea level with an automatic control system that has a setpoint temperature of 24-27 ° C and humidity of 80-95%. The test was conducted in a 4 × 2 × 2 m mushroom barn with a capacity of 600 mushroom bag logs. The performance test results showed that the daily temperature and humidity without control ranged from 24.10-35.19 °C and 64.28-99.90%. In contrast, with automatic control, daily temperature and humidity were recorded between 25.10-30.09 °C and 80.84-99.90%. This study shows that the automatic control system Effectively maintains optimal environmental conditions for oyster mushroom growth.
