Abstract

Wireless Sensor Network is a wireless networking technology that connects multiple sensor nodes into a single network that work together to perform specific functions and objectives. In a network there is a set of rules that underlie the performance of the network itself, the rule is called protocol. OLSR is one of the proactive routing protocols. Unlike the LSR, the OLSR protocol applies the Multi Point Relay (MPR) mechanism to prevent duplicate message reception. In this research the implementation of OLSR protocol on Arduino Pro Mini and NRF24L01 is done to see how OLSR protocol performance in Arduino device and NRF24L01. The implementation will be divided based on the package message according to OLSR protocol. The results of this study indicate that the OLSR protocol can be implemented in Arduino Pro Mini and NRF24L01 devices. The results of this study indicate that the OLSR protocol can be implemented well on base station nodes and node sensing, which consists of Arduino Pro Mini and NRF24L01 devices. The packages used on the system are HELLO, MPR packets, mpr_info packets and sensor data packets. In addition, in the system there are several processes that update the routing table, forwarding and MPR node selection. Tests for HELLO packets, MPR packets and data sensor packets overall have a 100% success percentage. In addition, the authors also tested the convergence time of the protocol with an average value of 46002,9ms.

Abstract

Kutai Timber Indonesia Kota Probolinggo is a manufacturing company focusing on a timber production and marketing in Indonesia. In such a large company, Standard Operational Procedure (SOP) is definetly used to support the business process. In fact, there is a certain deviation from what is expected to happen and what is actually happened. This deviation might lead to fraud. Because of this, evaluation should be done so that this deviation will not harm the company. In this case, the evaluation is done by extracting event log from the ERP using Disco Tools and ProM Tools and implementing Process Mining as a method. It was found that there are 46 cases do not match the SOP from total 68 cases received in a month. The evaluation results show that the SOP model has fitness 0.88 and structural appropriateness 1.0 because the generated model is derived from YAWL simulation, so the process flow fits to the expected business process. Meanwhile, the model which is generated from event log ERP system has fitness 0.81 and structural appropriateness 0.421 because the activity contained in ERP has many variations and inconsistencies such as repetitive activities, deleted activities, and inserted activities, so that the model can not fully described all traces in the event log.
