Abstract

Snort merupakan salah satu sistem deteksi intrusi (IDS) open source yang banyak digunakan untuk mendeteksi intrusi atau aktivitas mencurigakan pada lalu lintas jaringan. Snort akan memberikan alert atau peringatan apabila terdapat serangan yang terdeteksi, kemudian mencatatnya pada log. Data log IDS Snort tersebut dapat digunakan oleh administrator jaringan untuk menganalisis kerentanan sistem keamanan jaringan. Analisis data log dapat dilakukan dengan berbagai cara, salah satunya mengimplementasikan algoritma clustering seperti Fuzzy C-Means (FCM). Implementasi algoritma pada penelitian ini berbasis Python 3 dan bertujuan untuk mengelompokkan serangan pada data log menjadi 4 kategori risiko, yaitu low, medium, high, dan critical risk. Hasil analisis penelitian ini adalah berupa pengelompokkan serangan dengan FCM dan visualisasi jenis serangan yang berhasil dideteksi oleh IDS Snort. Tahap evaluasi dilakukan dengan Modified Partition Coefficient (MPC) untuk menentukan validitas hasil clustering FCM. Kata Kunci— Clustering, Fuzzy C-Means, Log, Snort.

Abstract

Network Management System is a device with piles of capabilities to help the network engineer to utilize independent network component especially in a wide framework. Network Management System have the capabilities to identify, configure, monitor, update, and troubleshoots the wired also wireless network devices as well. Udayana University have been utilized some type of platforms to monitor and manage its network, those platforms are Cacti and OpenNMS. However, both of those platforms didn’t meet as what the experts called it as Integrated Network Management System. Thus, EVOMAC present as a solution to simplify the workflow of the network engineers. EVOMAC is an acronym for Evolved Network Management System Application that fused with OpenNMS, PostgreSQL, Telegram, and NodeJS. EVOMAC is also cooperates with four basic API methods that build its system such as POSTMethod, PUTMethod, GETMethod, and DELETEMethod. All of those API methods are the foundation of the command functions /start, /nodes, /addnode, /deletenode, /alarm, /category, and /requisition. Each of the command function has their own response time duration since it is related to the speed of the connected internet and the amount of people who has access to it.

Abstract

The Telkomsel Renon Building serves as the regional telecommunications service office for the Bali and Nusa Tenggara area, covering an area of 5072 m2 with a PLN power capacity of 555 kVA. PT Telkom is committed to reducing energy consumption by implementing ISO 50001 energy management. Despite this, the use of 14 smart meters is still manually conducted, leading to a lack of real-time energy usage information. PLN data indicates an average energy consumption from 2017 to 2023 of 628.271 kWh, with an average annual cost of Rp. 696.915.017. Factors such as electrical equipment, room size, activities within, and building insulation affect the building's energy consumption. Inappropriate activities relative to room capacity can lead to energy wastage. One solution proposed for accurately monitoring energy usage in real-time involves the development of an Internet of Things (IoT) based application using Blynk. IoT is implemented in large meeting rooms with Central Split Duct AC and small meeting rooms with Split Wall AC. Measurement results indicate significantly higher energy consumption in large meeting rooms, reaching 4207.83 kWh, compared to only 467.06 kWh in small meeting rooms for similar activities. Discussions with users of small meeting rooms revealed their comfort and successful achievement of meeting objectives. By utilizing small meeting rooms, energy consumption can be reduced by up to 88.9%. Based on these findings, recommendations for room usage SOPs have been formulated for the Telkomsel Renon Building to realize energy-efficient practices towards green building standards.

Abstract

Air adalah  kebutuhan yang sangat penting, ketersediaan air tetap harus selalu ada baik di rumah tangga, perkantoran, tempat-tempat umum  ataupun industri. Ini menyebabkan peran penampung air menjadi penting untuk menjamin ketersediaan air secara pasti. Mekanisme pengukur ketinggian permukaan air secara otomatis diperlukan untuk menjaga ketersedian air ini. Salah satunya dengan membuat sensor pengukur ketinggian air yang diumpanbalikkan dengan pompa pengisi bak penampung air tersebut. Resistor variable  tipe trimer potensiometer (trimpot) multiturn  dapat dipakai sebagai elemen sensor dimana perubahan ketinggian air  akan memutar knob atau trimer resistor variable. Ini akan menghasilkan perubahan tegangan yang merupakan masukan analog bagi ADC 8 bit tipe 0804. Keluaran atau output digital dari ADC akan dimasukkan ke port mikrokontroler AT89S52 yang selanjutnya diolah untuk ditampilkan berupa ketinggian air dan kondisi pompa air pada display LCD 16 x 2 tipe M1632. Rangkaian ini juga dilengkapi dengan pompa air yang hidup matinya diatur dari mikrokontroler yaitu pompa akan mati jika wadah penampung hampir penuh dan hidup kembali saat wadah penampung  hampir kosong. Hasil pengujian  peralatan ini menunjukkan bahwa peralatan ini sudah mampu menunjukkan ketinggian air pada suatu wadah penampung  berupa display LCD yang sama dengan keadaan sebenarnya seperti yang ditunjukkan pada mistar. Pompa air yang digunakan juga sudah berfungsi yaitu memompa air ketika ketinggian air pada bak penampung 5 cm dan mati ketika ketinggian air hampir penuh (25 cm).

Abstract

This paper designed a medical image compression scheme using DWT with mother wavelet Coiflet and Symlet. Thresholding and quantization process are the key to lossy compression in this scheme, and the outputs will be coded with Huffman or Arithmetic coding. There are four different codec combinations namely: Coiflet-Huffman, Coiflet-Arithmetic, Symlet-Huffman, Symlet-Arithmetic. Compression performance of each codec will be analyzed based on PSNR and compression ratio. The compression testing used 3 grayscale medical images with dimension of 160x160 pixels. The most optimal PSNR dan rate are produced by Symlet-Aritchmetic codec with recommendation threshold value less than 12. Threshold value above 12 causes PSNR of the reconstruction image will be below the minimum PSNR stardard for digital image, which is of 30dB.
