Abstract

Single sign-on (SSO) is a session authentication process that allows a user to login by using user registered identity and password in order to access appropriate applications. The authentication process takes the user in to login for all the applications they have been given rights to and eliminates further prompts when they switch applications during a particular session. Its implementation will provide a reduction of password burden to access many applications for every login process. Ease of access through a single account needs to be addressed carefully to ensure the authentication credentials that are not scattered and known by others. Currently, there are several open source SSO authentication methods available. However, the use of existing authentication methods is still vulnerable to attack, such as Man-In-The-Middle. In this study, SSO authentication algorithm using One-Time Password (OTP) is proposed using a combination of time synchronization and salt value. These combinations are used to verify user session while accessing any application with SSO mechanism. The results show that the proposed OTP algorithm can handle SSO authentication process in good fashion and also protect from Man-In-The-Middle Attack.

Abstract

Solar panels are an essential part of a system of electrical source devices that receives light energy to be processed into electrical energy with direct current (DC) output. The main problem in the use of solar panels is that the production of power in solar panels is not constant due to the temperature and solar radiation changes. This non-constant power causes the solar panel output power to fluctuate and become unstable. This output power will be used in processing using the MPPT Perturb and Observe (PNO) method to obtain the maximum solar panel receiving point. This PNO method uses two input parameters and can be applied to all types of solar panels. This study aims to reduce the oscillation of the output power of MPPT using electronic power simulations on a three-level boost converter by combining PNO and Fuzzy MPPT methods. The Fuzzy method in this study uses the Mamdani inference method, which uses two inputs and one output. The boost converter was tested using a simulation on several conditions of sunlight received by solar panels. The simulation results show that the power output from the MPPT PNO and Fuzzy methods can reduce oscillation more optimally, 78.57%.

Abstract

Single Sign On (SSO) merupakan model autentikasi independen yang diimplementasikan Universitas Ubudiyah Indonesia (UUI) menggunakan Message-Digest Algorithm 5 (MD5) dan web service NuSOAP berbasis bahasa pemograman PHP. Sistem ini berjalan pada protokol Hypertext Transfer Protocol (HTTP). Faktanya penggunaan protokol HTTP ini sangat rentan terhadap berbagai jenis serangan karena data dikirim dalam bentuk plaintext tanpa ada proses enkripsi dan penerapan algoritma MD5 pada autentikasi login juga rentan terhadap serangan dictionary attacks dan rainbow tables. Disisi lain, Penggunaan web service NuSOAP juga menciptakan celah keamanan karena pengiriman dan penerimaan payload tidak dienkripsi. Saat ini diketahui sudah ada beberapa metode yang dapat digunakan untuk meningkatkan pengamanan kerentanan tersebut diantaranya yaitu menggunakan Hypertext Transfer Protocol Secure (HTTPS), Secure Hypertext Transfer Protocol (SHTTP) dan Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA). Namun beberapa hasil penelitian terkait memperlihatkan masih terdapat beberapa kelemahan dari penggunaan HTTPS, SHTTP dan CAPTCHA. Penelitian ini mengusulkan penggunaan algoritma Advanced Encryption Standard (AES) dengan pembangkit kunci dinamis dan metode One-Time Password (OTP) berbasis sinkronisasi waktu dengan kombinasi salt untuk meningkatkan keamanan pada autentikasi SSO UUI. Hasil pengujian menunjukkan penerapan algoritma AES dan OTP  dapat mengamankan proses autentikasi SSO  dari serangan dictionary attack dan rainbow table.

Abstract

Information is necessary for life because everything can not be done properly in the absence of information. The security problem is one of the most crucial aspects of a file containing sensitive information, for example, medical record files. Often, the file owner, designer, and manager of the information systems pay less attention to the security issues. One way to anticipate this is by using a cryptographic method, which is the science and art to keep the message security. This study aimed to evaluate the performance analysis and building a security system prototype of medical record files using the 4DES algorithm. The 4DES algorithm is a variant of the 3DES algorithm that is more robust and capable of protecting information properly. The 4DES security system has four keys; each key has a key length of 64 bits so that the total length of four keys is 256 bits and K1≠K2≠K3≠K4. The encrypted / decrypted files (Word, Excel, and Image)  using an external key of minimum eight characters (64 bits). During encryption, there was an addition of padding bytes in each of data block size to minimalized attack from the attacker using a CBC operation mode process. Results showed that the processing speed of the encrypted files using the 4DES was 1 second faster than that of using the 3DES algorithm. Also, the 4DES algorithm has superiority regarding of file safety, which has time enduring 3.45 x1056years longer to brute force attack technique which able to discover text file and the secret key.

Abstract

Most of Indonesia’s territory consists of oceans, presenting a significant potential for developing the fisheries sector. Shrimp is among Indonesia’s flagship commodities with substantial export potential. Internationally, Indonesia holds the fourth position as the largest exporter of frozen shrimp globally. However, shrimp cultivation faces various challenges, including declining water quality due to factors such as water sources and weather, which can adversely affect harvest yields. To preempt potential failures, employing smart devices and technology in shrimp cultivation offers an effective and efficient solution for monitoring and management. This study aims to analyze water quality monitoring in ponds considering the speed of data transmission from end devices to fog using Quality of Service (QoS) parameters like delay/latency, throughput, and packet loss. Data transmission tests were conducted at data rates of 5 Mbps and 10 Mbps, with a bandwidth of 1500 Mbps. The study involves three sensors—water temperature, pH, and salinity—placed in shrimp ponds. Test results showed a decrease in throughput by 1.54% at the sensor node and 2.99% at the sink node when packet data delivery encountered barriers like obstacles. There was a 74.13% increase in latency when the delivery distance extended to 35 meters. The achievable delivery range with low latency was up to 10 meters with barriers and 25 meters without. Thus, latency and throughput values vary depending on the presence of barriers and transmission distance. Barriers tend to increase latency and decrease throughput.

Abstract

Maintaining the temperature and pH of water in fish farming is important to maintain the survival of the commodities being cultivated. Snakehead fish as one of the freshwater fish cultivation commodities, live in a temperature range of 25° to 32°C, and a pH of 4,5 to 6. Changes in temperature and pH due to  differences in day and night and weather conditions can be mortal for the fish. To help the fish farmers maintain water quality, in this research a prototype of IoT based temperature and pH monitor and control was built using Arduino microcontroller, that  can be accessed through a mobile application on Android smartphone. The test results show that the prototype has successfully control the temperature by turning the heater on when it dropped below 25°C, turned the acid solution pump on when the pH felt below 4.5, and alkaline solution pump when pH was above 6. Continuous sensor readings are able to  maintain the stability of water quality.
