The integration Internet of Things (IoT) generally identical with Cloud computing. IoT aims to connect the heterogeneous objects/devices with each other, in order to communicate or exchange data/information. Development of the Cloud IoT system, have challenges to achieve these objectives, such as middleware, interoperability and scalability of system. In this paper, we will discuss the solution of the challenges, by applying the publish and subscriber method, using MQTT protocol. This paper, proposed of architecture model design, which is implemented in the form of system topology. This topology apply to monitor and control the provision of nutrition hydroponics, accessible as a Cloud SaaS. From the test results, average node response time needed to connect and communicate with IoT Cloud system (online) is 7.21 seconds. The time required to declare offline state of a node is 21.55 seconds. The test results of Cloud IoT (broker), obtained that number of nodes for each level QoS, affecting resource usage of CPU and throughput. The highest resource usage of CPU is 19% of 2.0GHz and throughput TX/RX is 34.68KBps/49.4KBps. This result obtained from 1000 nodes scheme testing with 1 messages/node, by using simulation application, on QoS level 2. The average of minimum bandwidth used is ± 0.90Kbps by 1 publisher, to send 1 message with 115 Bytes of payload size, on each 3 levels of QoS MQTT, and approximately ± 0.04Kbps on subscriber to receive that message
