<![CDATA[The development of smartphones as tools used in research provides many benefits in several fields, including education, health, and agriculture. Digital image research developed in mobile apps can help us choose the best decision so that the results are by what has been planned. One of the developments in entomology is entomology research that uses digital imagery. In the dataset activity, researchers used the anopheles’s wings type as much as 22 image data. Fifteen types of Anopheles were used by the researcher with 100 experiments as test data. Image training and identification have the same process, taking pictures from a gallery or directly using the camera from an Android device. Preprocessing step in applications includes 1) converting image pixels to 100x100 pixels, then this pixel size becomes the standard of use in applications. 2) Convert an image to a binary using a threshold algorithm; this event is commonly called the Image Binaryization Process. Images derived from the threshold process are converted into one-dimensional vectors. Training Image and image identification using the Eigenface algorithm. The basic principle of the Eigenface algorithm is to quote the unique information of each image and then compare it to the image in the dataset. Identification with anopheles applications results in a good accuracy value with a success rate of 94.29%, with FMR value = 4.62% and FNMR = 2.78%.]]>

<![CDATA[As the number of vehicles is increasing, the air quality in the environment becomes more polluted. This problem happens due to concentration of carbon dioxide (CO2) is high in the air and it can lead to various health issues. The air quality meter is an important device to measure the concentration of CO2 in the air. In this study, an air quality monitoring system is built using Arduino Nano along with IoT technology to measure parameters such as CO2, temperature, humidity, and heat index. FreeRTOS is used to run multiple tasks consisting of display and transmit concurrently. MQ135 and DHT22 are used to sense CO2, temperature, humidity, and heat index respectively. Data will be sent periodically to a web server using ESP8266 Wi-Fi module through secure HTTPS POST protocol. On the back-end side, a web server is employed to receive sensor parameters as well as to build a website application securely by which users can monitor it remotely. The system was tested to monitor CO2 in 4 different locations of Pangkal Pinang city, Indonesia. The results showed that the averages of CO2 concentration in Housing Indo Graha, Morning Market, Dea Lova Park, and Pasir Padi Beach are 411.37 ppm, 485.97 ppm, 416.45 ppm, and 444.43 ppm respectively. Based upon the results, public place i.e. Pasir Padi Beach has higher CO2 concentration meanwhile public place with organic waste i.e. Morning Market has the highest CO2 concentration.]]>

<![CDATA[Prediction of pepper data is done by looking at several variables to get optimal results. From the production data of the pepper harvest, the information is not yet available to farmers. By using the fuzzy method, the author tries to create a system to estimate the results of predictions by considering the parameters of the number of seeds, fertilizers, pesticides and labor. The combination of these variables can produce an intelligent system that is able to learn and adapt to environments with incomplete and precise data variations and fuzzy logic that has the ability to translate expert knowledge by using linguistically constructed rules. From the results of the experiments conducted, the results obtained were 900 kg of production data.]]>

<![CDATA[Computer network security is an issue that needs attention, along with the valuable and confidential information that passes through the network. The increasing use of networked computer systems has also led to an increase in cybercrimes worldwide, including Indonesia. The types of attacks carried out vary and go through several phases. Among the initial phases of the attack is the port scanning process. The process uses specific programs, such as Nmap (Network Mapper), to check on the target/victim side which ports are open and can be exploited for further attacks. IDS (Intrusion Detection System) is here to anticipate external attacks; IDS is used to detect suspicious activity in the system or network. This study aims to create a computer network security system that is lightweight, based on open-source, easy to set up, and can be analyzed by administrators by using Maltrail. Maltrail itself is a monitoring service used to detect dangerous traffic/traffic in a computer network, by utilizing a blacklist containing a list of dangerous or suspicious elements/sources. This study describes the stages of Maltrail installation and how Maltrail can detect the suspicious network, in this case, the port scanning business using Nmap. As a result, Maltrail can be relied on to log and notify network administrators of illegal system entry attempts/intrusions when there is a port scanning process from outside. Thus, it is hoped that with the existence of IDS, handling of an attack can be carried out earlier and prevent fatal consequences.]]>

<![CDATA[Online learning assessment and evaluation has been widely used using the Learning Management system (LMS). However, the form of the questions is still based on multiple choice. Evaluation and form of questions in LMS need to be developed by exploring metacognitive thinking. The LMS plugin supports Essay-based questions and assessments, it's just that this plugin needs to be supported with file submissions and metacognitive assessment rubrics. Therefore, this research aims to customize and test the usability of Auto Essay File Grading (AEG) metacognitive assessment based on LMS. This study uses a quantitative descriptive approach conducted at the Faculty of Engineering, Universitas Negeri Makassar, with lecturers and students as respondents. Data were collected through the USE questionnaire and analyzed using descriptive statistics. The results of the analysis of AEG usability testing from the point of view of lecturers and students who have the highest average are a usefulness. For the lowest average of the lecturers is the ease of use and from the student, the side is the ease of learning. These results also prove that the AEG application/plugin needs improvement in terms of ease and practicality of use so that users learn how to use it faster. Recommendations for ease of use and learning are discussed and explained further, along with the improved display, answer keywords, and minimizing irrelevant menus.]]>
