The development in Information System of Mail and Archives Management at the Governor Office of West Nusa Tenggara is still supported by manual process off disposition, archiving, search, and mail recapitulation report process. The aim at developing this system is to help the managing and archiving mail so staff in subsection Expedition and Archives can manage mailing and archiving quickly and precisely. This system is developed based on the programming language of HTML and PHP using framework CodeIgniter. It is examined through the Black box technique. The result is that every menu provided functions perfectly. The workflow of the information system has been suitable with the workflow of every work unit in the governor office of West Nusa Tenggara.

Based on the of tourist visits of West Nusa Tenggara from 2013 to 2017 obtained from Tourism Office of NTB Province the number of tourist visits changes every year. a prediction is needed to estimate the number of tourist visits in the upcoming year to help the government in making policy. The Tourism Office currently estimates the tourist visit based on the events that will be carried out. There are no mathematic calculations in estimations. This study uses Backpropagation to predict the number of tourist visits. Backpropagation is a good and accurate in predicting process involving fluctuating data. This study aims to examine the effectiveness of the backpropagation in predicting the number of tourist visits based on the minimum value of the Mean Square Error (MSE). Using a maximum iteration of 1500, learning rate 0.3 and the number of hidden layers 21 produces the minimum MSE value of 0.003901 and the prediction of tourist visits in 2018 has the most tourist arrivals in July 2018 of 465.202 tourists and the lowest visit was in February 2018, which estimated to 236.864 tourists.

Information technology governance is an integrated part of the management of organizations that govern leadership, the organization of process structure arrangements that govern information technology is used as optimally as possible. Work processes and relationships between the office community, researchers and various levels of interests and stakeholders. COBIT 5 is a company that provides services to companies, both companies, organizations, and management in managing and managing assets or IT resources to achieve company goals. It human resource in West Lombok is currently not well managed, Which hes not yet fulfilled the need for IT human resources in the office of West Lombok To solve this problem the authors carry out ITgovernance using the framework COBIT 5 On DISKOMINFO west Lombok. On DISKOMINFO West Lombok. This study will provide recommendation for improvement of IT problems the exist in diskominfo West Lombok and cand be used as a reference, especially in the managed of IT human resources and can improve the performance of DISKOMINFO west Lombok. On DSIKOMINFO West Lombok using to IT processes APO01 (management framework IT) and APO07 (human resouces). The result of this analysis are the capability level of IT governace that reflects the condition of IT governance in DISKOMINFO West Lombok. With refenace to the capability level provided by the cobit 5 framework, namely from level 1 (performed) to 5 (optimising). Key words: information technology, DSIKOMINFO COBIT 5

This research was conducted based on existing problems in the registration system, scheduling, and announcement of the results of the TOEFL test at the Language Center of the University of Mataram. Where registration, scheduling, and the announcement of TOEFL test results are done manually which requires prospective participants to register directly at the language center of the University of Mataram. This system is expected to simplify the registration process, scheduling, displaying available quotas and checking TOEFL test results. This system was built using a CodeIgniter framework, XAMPP as a web server and MySQL PhpMyadmin as its database server and built with the waterfall model as a system development method. This system is tested by the black box method and user interface testing will be used subjectively testing using the mean opinion score (MOS) by involving several respondents. Based on the test results of the Mean Opinion Score method, it can be concluded that 66.1% of the respondents agreed and 33% of the respondents strongly agreed with the TOEFL Information System Design in UNRAM.

Destination-Sequenced Distance Vector Protocol (DSDV) is a proactive protocols available in Ad-Hoc mobile network where this protocol is not suitable for use on networks with high mobility because DSDV needs to update routing tables regularly if there is a link between nodes that is disconnected because there are nodes that move out of the transmission signal range and the AODV protocol is a protocol that matches high mobility because it is reactive. So that in a stable route search can be done by selecting a route that has a small chance of being interrupted. LET algorithm is used in the DSDV protocol to find the most stable route by knowing the estimated time between two nodes to remain connected based on the position, speed and range of the transmission signal then compared with the AODV routing protocol based on parameters such as throughput, packet delivery ratio and delay. The results showed that the S-DSDV routing protocol has better performance than the standard DSDV routing protocol. Key words : DSDV, Link Expiration Time, AODV, MANET, Routing Protocol
