Abstract

Electronic devices must have a lifetime limit and may be damaged at any time. A system consisting of several electronic devices will fail if the crucial component is damaged. Therefore, crucial components in a system should be more reliable. To improve system reliability a mechanism such as Hardware Redundancy can be applied. Hardware Redundancy is a mechanism to improve reliability by duplicating important components as backup. There are several types of Hardware Redundancy mechanisms, one of which is Cold Standby Redundancy which uses the unpowered backup concept. The Cold Standby concept is to add a duplicate of an important component that standby without a power supply and will be active when the component is damaged. In this study Cold Standby Redundancy is applied to an automatic door lock system based on Arduino Uno and RFID. An important component of the system is Arduino Uno which acts as a controller in the system. Implementation of cold standby redundancy on this system uses a third party device (Arduino Nano) as the fault detector of main Arduino Uno (master). Through I2C serial communication the master sends keep-alive status periodically to the fault detector as a sign of whether it is still operating or is being damaged. In addition there is a switch device in charge of switching the system control to master or slave. The fault detector sends the trigger to make a switch to the switch device when it detects damage to the master. Based on the results of tests that have been done, system reliability increases after applying the Cold Standby Redundancy mechanism. System reliability value increased by 15.45% for a year operating time.

Abstract

Clove plant have high economic value and one of many export commodity of Indonesian plantation product, in Wonosalam region Jombang Regency there are less well groomed clove farm because the owners are not at all the times in the farm, and thus the plant susceptible to disease and reduced yields from the clove harvest. Needed a way to help farmers to know the types of diseases that attack the clove plants, then made a clove plant diagnosis system using the algorithm Modified K - Nearest Neighbor (MKNN). The diagnostic system will provide clove plant disease information based on inputs of observable symptoms of the plant. MKNN algorithm is the development of KNN algorithm by adding calculation process of data training validation and weight voting. Validation calculation aims to overcome the problem of data that deviates on the KNN algorithm in order to avoid bias and weight voting aims to calculate the weight of the data. Accuracy of clove plant diagnosis system using MKNN algorithm is 96.67%.

Abstract

MQTT Protocol (Message Queuing Telemetry Transport) is widely used in wireless communication medium on IOT (Internet of Things). On the other hand, the use of wireless medium has a disadvantage. As an example, the data are highly vurnerable to eavesdropping (sniffing data). The dangerous impact of eavesdropping or sniffing is that the loss of security. Therefore, it is required to have a mechanism to ensure data security. Trivium algorithm is one of the cryptographic synchronous encryption cryptographic algorithms used to secure data and Trivium is tested well and Trivium is assigned as a stream cipher encyption algorithms by ISO/IEC 29192-3; 2012. Raspberry Pi is used as a publisher, subscriber and virtual machine as a broker. Publisher will encrypt the data before the data and topic are sent to the broker. Broker will forward the data to the subscriber that is subscribed. After the data is received by the subscriber, the data will be decrypted into plaintext. Here are the results of the study; keystream result to the vector test is valid, validation result of encyption and decryption is valid, the result of sniffing data of Wireshark shows that the data cannot be read by an unofficial authority, and the result of six functional systems showed that all of the functional work well, the result of the average time to produce keystream is that 0.034886725 seconds, encryption process is that 0.047045873 seconds and decryption process is that 0.053834003 seconds

Abstract

Information system success has a different understanding from technical view, semantic view, and effectiveness. To measure this success alone using only a few variables is not enough but must be measured in its entirety. DeLone emphasize this so that the measurement results can be more thorough than taking measurements only on certain variables. Variables used in this study are system quality, information quality, service quality, usage, user satisfaction, and net benefits. This study aims to do success analysis on FILKOM's website. FILKOM's website has a very important role as a media promotion for Faculty of Computer Science Brawijaya University and online services that provide information for students, lecturers, and other academic community. The implementation of DeLone and McLean models shows that the success rate on FILKOM website is moderate. The use of Pearson product moment analysis justifies the research hyphothesis that each variable has a positive and significant relationship on other variables connected according to DeLone and McLean models. Variables that have a strong influence on other variables are information quality and service quality on user satisfaction variables. Thus, to improve user satisfaction in using or accessing FILKOM website, SI departments must fix how the information provided to always fit with the needs of users and how users can contact the SI departments easily if there is an error.

Abstract

To maintain quality of service, a café must pay attention to several aspect. One of them is the availability of the menu served by the café. The availability of the menu also depends on the availability of the ingredients needed to make it. Therefore, the café manager need to make sure that the ingredients is enough and resupplied fast enough when needed. Push Notification is a technology which allow information to be delivered to stakeholder via instant alert on their smartphone. This concept can be used by café manager to monitor the availability of ingredients, so that any insufficient ingredients can be resupplied fast. Analyical Hierarch Process (AHP) is used to determine the priority of ingredients that needed to be resupplied first. Ingredient stock, the number of menu using corresponding ingredient, and ingredient price are used to determine supply priority. The result of using both method reach 68% in accuracy, and 80% in delivery rate of push notification.
