Judul: Perbandingan Kinerja Eap-Tls, Eap-Ttls Dan Eap-Peap Sebagai Protokol Autentikasi Pada Jaringan Nirkabel
Abstrak: Security is one of the most important issue in wireless networks (IEEE 802.11) and WPA (Wi-Fi) Protected Access) is the current standard security protocol. WPA security process is divided into two sections, authentication and encryption. The authentication process is crucial because it is the first process executed before user can access the networks. Therefore, it must not only safe, the authentication process must also be done quickly. WPA has two modes of authentication namely Personal (Pre-Shared Key) and Enterprise (802.1x). EAP (Extensible Authentication Protocol) is a standard authentication protocol that is used in WPA Enterprise. EAP-TLS (EAP-Transport Layer Security), EAP-TTLS (EAP-Tunneled TLS) and EAP-PEAP (Protected EAP) are the three most widely used EAP methods today and has been certified by the Wi-Fi Alliance. All three EAP methods are equally implement TLS protocol for securing data during the authentication process. This study will compare the performance of the three EAP methods with the three criteria for comparison of speed/ time, the amount of packet size, and number of steps required during the authentication process. The results show that EAP-TTLS has better performance than those of EAP-PEAP and EAP-TLS.

Judul: Analisis keamanan wireless local area network standar 802.11: Kasus PT. Masterdata Jakarta
Abstrak: tan bagi pengguna, salah satu teknologi tersebut adalah Wireless Local Area Network (Wireless LAN). Teknologi wireless LAN ditujukan sebagai protokol pengganti kabel yang efisien, berdaya rendah dan murah. Karena transmisi informasi melalui media udara, maka ada kemungkinan terjadinya ancaman dan gangguan terhadap transmisi tersebut. Sebuah protokol keamanan standar didefinisikan dalam wireless LAN yang disebut Wired Equivalent Privacy (WEP). Terdapatnya berbagai titik kelemahan dalam protokol WEP yang dapat dimanfaatkan penyusup, maka dituntut dikembangkannya teknologi keamanan baru. Sebuah standar keamanan yang menjanjikan di masa depan sedang dalam tahap pengembangan yaitu protokol 802.11i yang membutuhkan perubahan dari perangkat keras yang sudah ada saat ini. Selama menunggu perangkat keras yang mendukung 802.11i muncul dipasaran maka solusi sementara keamanan wireless LAN menggunakan Wireless Protected Access (WPA) yang dirancang untuk dapat digunakan pada perangkat keras yang ada saat ini. Kebutuhan mendesak akan keamanan yang tangguh dengan keterbatasan perangkat keras yang ada menyebabkan timbulnya solusi alternatif dengan menggunakan protokol di luar standar jaringan wireless LAN, yaitu dengan menggunakan Web Proxy dan Virtual Private Network (VPN). Solusi keamanan tersebut diharapkan memenuhi dasar keamanan yaitu Otentifikasi, Akses Kontrol, Kerahasiaan, Integritas Ketersediaan dan Tidak terjadi penyangkalan. Penulis melakukan eksperimen serangan dan analisis keamanan wireless LAN terhadap WEP, WPA, Web Proxy dan VPN. Dari hasil eksperimen dan analisis didapat bahwa usulan solusi Web Proxy dan VPN baik digunakan sebagai solusi keamanan wireless LAN.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
