Abstract

Indonesia is an agricultural country which has many agricultural commodities such as spices demanded by foreign countries and has a high trade value. Currently, the production and export of Indonesian spices no longer dominate the global market, Indonesia has lost its glory in the world spices trade. It is caused by many farmers who only use limited experience and knowledge to fertilize the spices which can lead to crop failure and a big loss. Based on these problems, I will design an intelligent system that can optimize the fertilization in agricultural spices so the farmers could get optimal fertilizer for agricultural spices by using Genetic Algorithms. Genetic Algorithms was chosen because this algorithm can be used in problem optimization in a wide search space quickly. Test result using 2 type of plant, 3 types of fertilizers, 100 population size, 700 total generation, 0.3 cr and 0.7 mr combination can meet the nutrient needs of plants. The best result of this system testing can save cost of 0.23%.

Abstract

Soil is a crusial component for plant growth. There are many parameters that used for soil examination, and one of its parameter is soil's dampness. Soil Laboratory Balai Pengkajian Teknologi Pertanian Jawa Timur is one of the work units that has a duty to examine the soil for plant nursery purpose. However, due to the conventional tools that they used sometimes the examination result is not as accurate as they expected. Because of that problem the author did some research to make a smart computing system that can be implemented on a tool that can maintain the soil's dampness automatically. Fuzzy Inference System Mamdani is used to calculate how long does it take to water the plants by using two variable inputs; initial dampness and water volume. Genetic algorithm is used to get an optimal membership function by optimizing the boundaries of each membership function. The output of this research will display the optimal time to water the plants. From the examination result we got an error value for about 2,516651, but after optimization the number is reduced to 0,000121. With that result we can conclude that using Fuzzy Inference System Mamdani and optimized with genetic algorithm is able to calculate how much time that it takes to water the plants and still able to get a good outcome. Keywords: Plants, fuzzy inference system, Mamdani, genetic algorithm, optimization

Abstract

The growing use of current information technology users, monitoring system is needed to facilitate network administrators to monitor the devices connected in a computer network. Currently network monitoring systems generally display information by polling device data every few minutes. This causes the administrator don't know as early as possible if something happens to the device being monitored. This study developed an SNMP based network monitoring system by implementing MQTT. MQTT uses the principle of publish-subscribe to communicating. MQTT is used because power-saving and lightweight messaging protocol. This research produces a network monitoring system which can monitored device information like CPU, load, and memory periodically and display it in graphical form and table in web interface. System development with implementing SNMP agent on monitored device and SNMP manager on NMS Server as publisher. Manager requested information to agent every 2 seconds. On the client side is implemented a subscriber to subscribe published data by manager and then processed on the web-based interface. From the test results show the processing time data by the server and client takes an average time of 2.029 seconds. For data processing time from server to client takes an average time of 1.210 seconds.
