Abstract

Dewasa ini, cakupan daerah layanan teknologi generasi ketiga (3G) secara bertahap terus mengalami peningkatan seiring dengan kecenderungan tingginya pemakaian komunikasi data oleh pelanggan. Untuk memberikan layanan yang baik, pembangunan infrastruktur jaringan menjadi penting. Namun, layanan yang ditawarkan dapat dipengaruhi oleh propagasi sinyal terima dimana jaringan dan pelanggan berada. Untuk itu, dalam penelitian ini kualitas sinyal terima pada pelanggan akan diukur dan dievaluasi berdasarkan parameter RSCP. Daerah yang menjadi sasaran pengukuran adalah daerah sub urban di kota Banda Aceh yaitu pada kecamatan Kuta Raja. Pengukuran RSCP ini dilakukan dengan mengintegrasikan perangkat lunak RF Signal Tracker pada handphone dengan sistem operasi Android. Pengukuran dilakukan pada Node B di kecamatan Kutaraja. Hasil yang diperoleh, menunjukkan RSCP yang diterima UE pada jarak 300 meter sebesar -85 dBm. Berdasarkan standar acuan, hasil ini menunjukkan nilai RSCP berada pada kuat sinyal terima dengan kategori cukup baik. Hasil perhitungan berdasarkan teoritis menunjukkan pada jarak 300 meter nilai kuat sinyal berada dalam kategori sangat baik yaitu -68,57 dBm untuk daerah sub urban.Kata Kunci : Node B, RSCP, Kuat Sinyal, Sub Urban, RF Signal Tracker

Abstract

The capacitive slit is a method of making the impedance value to be resistive. To achieve this goal is a challenge in addition to the slit antenna and gives impact to gain as one of the important parameters in antenna design. The antenna gain in a particular direction is defined as 4π times the ratio of radiation intensity in that direction to the power received by the transmitter antenna. In this research, the proposed capacitive slit method was tested on the hexacula omnidirectional broadband antenna operating on frequency 0.85-3 GHz and gain 4.8 dBi. The testing was conducted to obtain the gain improvement of the hexacula omnidirectional broadband antenna. The placement of the capacitive slit was implemented on double strip antenna with 4 times experiments. The best experiment result was obtained when three capacitive slits were placed on different strips. The capacitive slit was designed by analyzing the average value of input impedance before calculating the dimension of the capacitive slit that applied to the antenna. The experiment result shows that the best value of antenna gain is 7.19 dBi. The gain increment is linear to the number of capacitive slits applied to the antenna.

Abstract

ABSTRAKPada universitas, website dibangun sebagai jendela informasi elektronik yang menyediakan informasi tentang pendidikan tinggi. Namun, adanya celah keamanan pada website berpotensi untuk dieksploitasi bagi kriminal teknologi informasi. Berdasarkan masalah ini, fokus penelitian ini ditekankan pada aspek keamanan. Dalam penelitian ini, perangkat lunak OWASP digunakan sebagai alat uji. Kemudian, evaluasi dan analisis dilakukan terhadap kerentanan website terhadap serangan. Akhirnya, dengan menggunakan teknik Multiple Attribute Decision Making dengan metode Simple Additive Weighting dilakukan proses pemeringkatan kerentanan terhadap lima website universitas negeri di Provinsi Aceh. Hasil pengujian menunjukkan bahwa potensi kerentanan yang paling tinggi terjadi pada Universitas-2 dengan nilai rata-rata kerentanan, 1,72. Kerentanan ini menunjukkan adanya celah keamanan ini yang harus segera diperbaiki segera agar informasi yang tersedia menjadi akurat.Kata kunci: Website, OWASP, MADM, SAW, KerentananABSTRACTAt the university, the website is built as a window of electronic information that provides information about higher education. However, the existence of security holes on the website has the potential to be exploited for criminal information technology. Based on this issue, the focus of this research is emphasized on the security aspect. In this study, OWASP software is used as a test tool. Then, the evaluation and analysis carried out against the vulnerability of the website against the attack. Finally, using the Multiple Attribute Decision Making technique using the Simple Additive Weighting method, vulnerability rating was made to five public university websites in Aceh Province. The test results show that the highest vulnerability potential occurs at University-2 with an average vulnerability score of 1.72. This vulnerability indicates a security hole that needs to be fixed immediatelyso that the information available becomes accurate. Keywords: Website, OWASP, MADM, SAW, Vulnerability

Abstract

a b s t r a c tThe development of flood early warning technology has grown rapidly. The technology has led to an increase in technology in terms of communication and information. Internet of Things technology (IoTs) has provided a major influence on the development of early warning information system. In this article a protipe-based flood monitoring information system of Google Maps have been designed by integrating Ultrasonic sensors as the height of the detector, the Arduino Uno as a processor, U-Blox GPS modules Neo 6 m GSM module and as the sender of data is the height of the water and the coordinates to the station of the system informais flood. The design of the prototype produces information flood elevations along with location based Google Maps interface.Keywords:Flood, Arduino, Internet of Things Technology (IoTs), Ethernet a b s t r a kPengembangan teknologi peringatan dini banjir telah tumbuh dengan cepat.

Abstract

Cyber crime continues every day that is always trying to exploit security holes that can be infiltrated. The techniques used vary greatly and the intended target can befall anyone, whether government institutions, private institutions, organizations and even educational institutions. One of the techniques used by intruders is the SQLI attack on the web server. This disorder can cause the information presented to be unavailable normally. once control of the database successfully taken over by the attacker, the data will be easily controlled and other attacks can be done against the client. In this study, an assessment of SQLI attacks on senior high schools in some ASEAN countries was conducted. The analysis was performed on the web server of senior high school in seven ASEAN countries. In this article, methods the forensic used to analyze web servers against attacks SQLI. There is still a lot of web server that vulnerable to SQLI. From the analysis obtained on average 20.86% for the type of SQLI in each country. Of the 70 samples of the website showed a study of web server with techniques SQLI is the highest risk level of 27% in Web Server Singapore and lowest risk level of 7% on a Web Server the Philippines.
