Abstract

Communication between devices can be done in various ways, one of them is the Publish / Subscribe model that uses the MQTT protocol From the shortcomings that exist in JSON, such as long processing time, Google recently introduced a new data format called Flatbuffers. Flatbuffers has a better data format serialization process than other data formats. This paper will discuss the implementation and testing of the Flatbuffers data format performance compared to other data formats through the MQTT Publish / Subscribe communication model. Testing is done by measuring the value of payload, latency, and throughput obtained from each data format. The test results show that the Flatbuffers data format is very well used as a data extraction format based on data processing latency of 0.5002 ms and throughput 518.4649 bytes/ms with payload 0.996108949 character/byte.

Abstract

This research builds the detection of php scripts using the Forward Taint data analysis method. Research has been carried out to test this attack. However, the accuracy that has been inferred is still very low. This is getting higher because of the false positive generated. So in solving this problem, the forward taint data analysis method performs double checks that will reduce the positive false value generated. Accuracy resulting from this research reached 90%. These results outperform other existing methods.

Abstract

This research aimed to build a solar tracker for a floating solar panel and used long–range (LoRa) communication to harvest energy and monitor its process. With the rising demand for renewable energy in these recent years especially for solar energy, it needs to meet this demand to remain relevant for the upcoming years where it will have an even larger impact as we shift into clean energy. Monitoring single–axis solar trackers on rural areas difficult and cost–intensive. The purpose of a floating solar farm is to reduce the cost from buying/renting land. Floating solar panels cannot be monitored using wired because they are moving nodes in the water, it makes wired installation complicated. Hence, using wireless sensornetwork is a solution that allowsremote monitoring of floating solar panels in rural areas and makes moving nodes mentioned above possible. Testing wasperformed by sending 100 packets from the node to its gateway using LoRa modulation, and the gateway successfully received about 90% of the packets sent by the node. The vertical single-axis solar tracker used in floating solar managed to get 17% more energy than the fixed solar with a more stable income for the whole duration of sending 100 packets.

Abstract

One of the protection mechanisms for organizations to protect their data is through information security risk assessment. The main obstacle in this area is asset dependency. Previous research developments tended to produce models that were difficult to implement because they were only applied to small assets, in contrast to the complexity of implementation in the field. This form of problem solving is a workflow-oriented security assessment solution that provides security rationale from a holistic perspective. The weakness of complexity in workflow oriented then became the basis of this research. The proposed solution is a simplification by using combined nodes that enable a modular concept. The modular concept is then applied to a reliable model, a data flow diagram. The study output shows the contribution of offerings with assessment solutions that consider dependencies by simplifying asset complexity in workflows in a modular manner with data flow diagrams.
