The internet has created a digital society, where people from various circles can connect to each other and can be accessed easily. But despite being widely adopted, traditional networks are still widely implemented where these networks are complex and difficult to manage. Software Defined Network (SDN) offers a solution where managing a network becomes easier with the centralized controller. However, because of the ease of SDN in managing the network, SDN has a very worrying security gap where Attackers attack Controllers that are taken over by the network. By using a new attack method called Persona Hijacking that disrupts the identifier binding process, SDN will go through a testing process by comparing how long the Persona Hijacking attack will take time and how the impact of this attack using two scenarios. The first testing scenario combines DHCP with Controller and the second test scenario by separating DHCP and Controller. This study indicates that the second scenario produces a larger black-hole presentation, which is 66% and takes 10 seconds slower than the first scenario. © 2021 IEEE.

Farmers and agricultural newcomers often rely on intuition for plant nutrient management, leading to inaccuracies. This study presents a real-time soil nutrient monitoring and plant recommendation system using IoT and machine learning. The prototype integrates an ESP32 microcontroller, NPK sensor, soil pH sensor, and DHT11 with an application and a machine learning model. The model employs a hard voting method combining random forest, LightGBM, and support vector machine algorithms, deployed via Flask API and hosted on Vercel. Testing showed the system effectively monitors soil nutrients in real-time, with a pH sensor error margin of ±0.51 and NPK sensor readings displaying a non-linear increase in levels. The hard voting method achieved 98.5% accuracy, with recommendation processing taking less than one second (371.17ms) and CPU usage at 7%. System performance depends on internet speed, while recommendation accuracy is influenced by temperature and humidity. This system offers a practical solution for precision agriculture by optimizing nutrient application and plant recommendations. © 2024 IEEE.

This study presents an analysis concerning the use of standard operating procedures (SOPs) and identifying sources of resilience and brittleness in an emergency response exercise conducted as training for Rio de Janeiro State Fire Department's captains, Brazil. From the audiovisual record of the exercise performed by 35 young officers, it was noticed the partial activation of 13 SOPs relevant to the exercise. Not all steps under each SOP were activated or even used. Some possible reasons are the novelty related to the use of simulation as well as the exercise design. This bias in the SOPs use was somehow compensated by sources of resilience that contributed to the actions outcome. Positive and negative aspects of this relationship between standardization and resilience were observed and described, contributing to a better understanding of the activity analysis of these professionals. © 2016

Education is one of the basic and initial formations for the growth and development of a child in the process of obtaining a better future. Once the importance of education, the state really supports every citizen in achieving a decent education. The assessment system in each school has a different system, but the assessment system refers to the national education regulations that have been set by the government. Grade promotion aims to measure the achievement of learning outcomes in accordance with the standard of graduate ability and measure the value of quality. An important decision-making, especially in the field of education, is the decision-making to increase grades in school for students. In making the decision to increase this class, it should refer to the results of the competence or academic ability of the student, not because of the intervention of several parties who do not have the capacity to determine whether or not a student is promoted. Therefore, it is necessary to make a decision support system that will assist in obtaining a decision on the feasibility of a grade increase in students using the Fuzzy Inference System of the Tsukamoto Method. The results of this study are a decision support system that can determine the decision to increase grades in students. © 2022 IEEE.

The policy of the Ministry of Trade of the Republic of Indonesia which sets the highest retail price for cooking oil and then cancels it in early 2022 due to people's complaints about the difficulty of getting cooking oil in the market has received many responses from the public via social media. This study conducts sentiment analysis using Word2Vec and Bidirectional Long Short Term Memory (BLSTM) with the aim of studying the public's response to the removal of the highest retail price policy and effect of both skip-gram (SG) and continuous bag-of-words (CBOW), window size and dimension to the word similarity and accuracy. Data taken via Twitter in March 2022. The data then goes through preprocessing stages, manual labeling by experts, and word embedding using Word2Vec to be further classified using BLSTM. Data labeling produces imbalanced data where the largest is neutral sentiment (53%) followed by negative (27%) and positive (20%). ome of the words such as 'mafia', 'mahal', 'langka', 'tangkap', 'bongkar', and 'mendag' could become the government's attention. The similarity value of the SG model tends to have a higher value than CBOW at a lower word vector dimension. The model that gives the best performance results is the Word2Vec model with 50 dimensions, SG architecture and window size 5. This is shown in the accuracy of 0.71 which is the highest value and only shows slight signs of overfitting. Symptoms of over fitting will be more visible with increasing dimensions. © 2023 IEEE.
