Abstract

Utilization of Information Technology in local Irrigation system in Bali called ‘Subak’ is expected to be able to distribute water evenly to all agricultural needs. Later, there will be no excess or even lack of water, no arable or infertile in the agricultural land due to water and its also expected to be able to produce maximum agricultural production. This study uses sensors of Soil Moisture, Soil Temperature and Soil pH which are expected to control water requirements for agricultural land which are flowed automatically by the system from the reports received by the sensor and the server using the Wireless Sensor Network. Water distribution will be carried out by the system after receiving water demand from sensors embedded in agricultural land using fuzzy logic so that the shared water will be the same as the Subak irrigation system but more controlled, effective and efficient. This may lead to better level of soil fertility required by plants as well as increase the agricultural output . The use of the Internet of Thinks (IoT) in this study will produce information that is fast and can be accessed on the Internet by using SmartPhone media, PCs or other communication devices.

Abstract

The OPD LAN network infrastructure is used by users to access various services and applications that exist within the Bali Provincial Government, but in its operations there is no possibility of technical problems. Among 152 network disorders that occur during a year, it is known that the disorder that occurs in LAN OPD is more common in physical disorders (as many as 61 disorders) than logical disorders (as many as 24 disorders). In order to maintain the availability of OPD LAN network infrastructure, it is necessary to evaluate the OPD LAN network infrastructure using COBIT 5.0 which focuses on the EDM, DSS and MEA domains. The evaluation results of the OPD LAN network infrastructure resulted in a percentage index above 50%. Based on the ISO / IEC 15504 rating scale, the processes that are part of the EDM, DSS and MEA domains obtain L (Largely Achieved) status, which is still not fully achieved so that development and optimization of the current network infrastructure conditions are still needed. The results of the evaluation of network infrastructure that has been linked to the disturbance data record for a year, the process obtained in the EDM, DSS and MEA domains is recommended for development and optimization of DSS05, DSS01, DSS02, EDM03, DSS06, DSS03 and MEA02. The development and optimization is recommended towards the preparation of procedures in the form of integrated Standard Operational Procedure (SOP).
