<![CDATA[The process of fish farming will never be separated from dissolved oxygen level control devices such as aerators so that the cultured fish can grow and develop optimally. This is quite troublesome for fish farmers, especially for people who often leave their cultivation sites, so they cannot monitor directly. Therefore, a platform for remote monitoring is needed. This journal focuses on designing and developing a back-end system, one of which functions as a data communication medium from the IOT antares platform to the website built so that the website can be used to monitor and control IOT devices using the waterfall development method and HTTP communication protocol. this method and communication protocol were chosen because they are currently quite popular and very flexible to use. The results of this research show that data communication carried out by the server with Antares using the GO programming language can run well and quite efficiently. The system built is also able to accommodate several requests from users simultaneously with an average response time of 60ms, while the exchange of IOT device data with the website has an average response time of 3 seconds.]]>

<![CDATA[In Indonesia, significant variations in rainfall are a severe challenge, especially in the Special Capital Region (DKI) Jakarta, which is very vulnerable to flooding and the effects of climate change compared to other coastal areas in Southeast Asia. This flood caused considerable losses to society, industry, and government. Inaccurate predictions of rainfall lead to difficulties in anticipating floods and landslides, causing an expansion of the impact of these disasters. Therefore, a solution such as "Extreme Rain Index Prediction Information System and Rain Radar-Based Flood Potential Warning System for Jakarta” is needed. This system uses SANTANU rain radar and GSMaP satellite data to visualize real-time rainfall with Server-Sent Event (SSE) techniques. It also employs a Random Forest model to predict extreme rainfall and potential flooding by combining the output from PyStep-based radar nowcasting and Numerical Weather Prediction (NWP). Even though the predicted flood potential is accurate (93.75% accuracy, AUC 0.93), the prediction of flood movement using PyStep is not precise (RMSE 2.8, IoA 0.57), affecting the accuracy of the flood potential prediction. This system visualizes rain from SANTANU and GSMaP radars in real time and estimates the potential for flooding. Further efforts are needed to improve predictions of flood movements for better accuracy of flood potential information.]]>

<![CDATA[Pengendalian aliran listrik merupakan elemen penting dalam pengembangan outlet otomatis, terutama dalam konteks Portable Water Ionizer. Kemampuan mengatur dan mengelola aliran listrik merupakan aspek kunci dalam memastikan kinerja yang optimal dan efisien. Pengujian dilakukan ketika suhu air melebihi ambang batas yang ditetapkan yaitu 29°C (Nilai 29°C ditetapkan sebagai ambang batas berdasarkan hasil pengujian, dengan suhu air awal sebelum proses elektrolisis adalah suhu ruangan). Hasil pengujian menunjukkan bahwa ketika suhu mencapai atau melampaui ambang batas, relai secara efektif memutus aliran listrik dengan mengaktifkan terminal NO yang semula terhubung dengan aliran listrik. Pengujian juga dilakukan dengan pengukuran tegangan menggunakan AVOmeter pada batang elektroda yang menunjukkan adanya aliran listrik (24. 7V) pada batang elektroda pada kondisi normal dan tidak ada aliran listrik (0V) pada saat relay berfungsi. Hasil menunjukkan bahwa relai beroperasi secara efektif dalam mengendalikan aliran listrik sesuai perintah yang diberikan. Pengujian memastikan bahwa relai dapat memutus aliran listrik ketika kondisi terpenuhi, dan elektroda tidak memiliki aliran listrik ketika relai berfungsi dengan benar. Sistem ini memberikan solusi yang andal untuk menjaga kondisi air yang optimal di dalam PWI. dan elektroda tidak ada aliran listrik ketika relai berfungsi dengan benar.

<![CDATA[In previous research, a tool has been made to detect soil NPK nutrient content with a screen display on the device. However, the reading results of the system cannot be monitored remotely. This research aims to develop a self-built IoT ecosystem to monitor the readings remotely. On the device side, a microcontroller can connect to the internet via a Wi-Fi network. The communication protocol selected is the MQTT protocol based on the pub-sub model. The software chosen to present the data is Node-RED. The service is self-hosted using a personal computer (PC). To be accessed from the internet, a tunneling service is used. The data presentation service obtained can be accessed remotely. Based on the test results, the MQTT protocol allows sending data only in the size of tens of bytes with an average delivery time of under one second. The data is presented in a dashboard that can be accessed via the internet with a browser.]]>

<![CDATA[Scheduling is a very important factor for the learning process at school, it is also very important at SMK Telkom Bandung. At this school, the schedule is still done manually. Because of this, many problems occurred, there were schedule clashes and the teaching and learning process was hampered. Therefore, a scheduling system was created using a genetic algorithm which is one of the optimization algorithms and can be used in various case studies such as scheduling subjects at school. With the application of the genetic algorithm, it can produce an automatic and optimal subject schedule. From several trials on the genetic algorithm, the best fitness value is 1 with an average execution time of 14.42990657 seconds. The results of alpha testing and beta testing show that the website created is running well and is feasible to use. With this system, it is hoped that it will make it easier for admins, teachers and students to access schedules.]]>

<![CDATA[Robotic Process Automation (RPA) is an automation solution for creating content on social media. This RPA technology can imitate human behavior. This process is assisted by Artificial Intelligence (AI) to help produce video content using AI tools. Activities such as determining content topics, creating videos, saving videos and uploading them are done automatically. So that the resulting content can be maximized in its publication, it is necessary to determine a topic that can help it. Social media has trending topics which, if turned into content, can have an effect on increasing views, because the content can be more easily found by people who are interested in the content and motivate them to interact. Automatic content creation according to trending topics can be assisted through web scaping. Web scraping is a technique for getting information from websites automatically without having to copy it manually using Python. The implementation of web scraping is in the form of searching for topics that are trending on the Facebook platform.]]>

<![CDATA[Visible Light Communication (VLC) is a communication system that uses visible light as its transmission medium to transmit information signals with Light Emitting Diode (LED) and LASER light sources using visible light between 400 THz (375 nm) to 800 THz (780 nm). VLC has several advantages over the use of radio frequencies in a system. Performance analysis is needed to prove these advantages. Performance analysis was carried out using a mathematical computational simulation using google colab with the python programming language. By taking into account the power allocation (?) strategy in the form of gain ratio power allocation (GRPA) and static power allocation (SPA). The interesting thing from this research is that the power allocation in the VLC system greatly influences the resulting performance. So, it can be locked that the SPA power allocation strategy can be adjusted by producing ?? = 1 and finding the optimal BER value in the range of 10-6 to 10^-3.]]>

<![CDATA[Heirlooms are very valuable items because they have a strong historical value. But in reality, many heirlooms are damaged as a result of the negligence of visitors who want to see the heirlooms or because of a disaster. Photogrammetry is a technology that is developing and is often used for today's industrial needs so that it offers an alternative solution for documenting heirlooms in the form of 3D models. This study aims to implement photogrammetry to document heirlooms. With the application of this technology, it is hoped that it can be used as a prevention or solution if heirlooms are damaged because we can make new duplicates of heirlooms based on 3D models that have been made. This research was conducted at Kanoman Palace, Cirebon City. The results of photogrammetry after it is implemented show that all needs are met and can be used as needed. The results of the questionnaire to the Kanoman Palace and people in Cirebon City, showed a figure of 73.7% strongly agree that the photogrammetry results are similar to the original heirlooms and strongly agree that by making 3D models of heirlooms can be used as prevention and solutions if the heirlooms are damaged.]]>
