<![CDATA[The vannamei shrimp is a type of shrimp that has a natural habitat in the Pacific Coast, and Mexico. This shrimp entered Indonesia in 1996 when tiger shrimp experienced a decline in production due to disease attacks caused by the White Spot virus. Demand for this shrimp immediately increased rapidly, requiring innovation to keep shrimp yields in line with market demand. The problem in vanamei shrimp farming is water quality, especially water temperature conditions where shrimp live. This shrimp prefer water conditions that have temperatures around 27-29°C. A water quality control system developed to maintain water conditions in accordance with the best conditions for P. vannamei shrimp to increase yields due to reduced mortality rates. Based on this problem, an IoT based water quality control system for the shrimp is developed. Meanwhile, this work is aimed at developing the application supporting this system.]]>

<![CDATA[A smart grid aims to integrate alternative and renewable energy sources. NDN has the advantage of being better than IP networks and can optimize the delivery of information. The concept of Named Data Networking (NDN) is designed for smart grid systems. This study aims to implement the NDN concept on a smart grid system and analyze forwarding and caching strategies. The implementation of the system strategy is supported using the NDN network topology, which is based on IEEE 39. The author evaluates network performance by paying attention to parameters such as delay and cache hit ratio. From the data the author obtained, it can be concluded that the best route-LRU and client control-LRU systems are better choices to be implemented in a smart grid communication system than the best route-FIFO and client control-FIFO systems. In other words, the LRU caching override method is superior to the FIFO caching override method. Meanwhile, the forwarding method does not show significant graphical results. This happens because the forwarding method that the authors use has the same route determination. Something that differentiates between the best route and client control is only the control of selecting the path. The best route is controlled by the producer, and client control is controlled by the consumer.]]>

<![CDATA[This research analyzes public sentiment on “Program Makan Siang Gratis” using the KNN algorithm, enhanced with the SMOTE technique, to provide insights and recommendations for policymakers aiming to achieve “Indonesia Emas 2045”. The study employs Google Colab and Python for testing. KNN is used for sentiment analysis and classification, with SMOTE addressing data imbalance. Results from two scenarios without SMOTE and with SMOTE show that performance is more optimal without SMOTE, as SMOTE decreases performance by 34%. The k4 parameter yields the best results: 76% accuracy, 57% precision, 77% recall, and 65% F1-Score. Analysis of comments from the “tempodotco” YouTube channel reveals that public sentiment towards the program proposed by President Prabowo Subianto and Vice President Gibran Rakabuming Raka is predominantly negative]]>

<![CDATA[Heterogeneous Networks (HetNets) that integrate Wi-Fi, 4G, and 5G technologies present significant challenges in resource management and power allocation. This study evaluates the performance of resource block (RB) allocation in a two-level HetNet model consisting of one macro cell base station (MBS) and four small cell base stations (SBS). Utilizing K-Medoids clustering, allocations are analyzed under various conditions using Greedy, Auction, and round robin algorithms. Simulations reveal that the Greedy algorithm outperforms the Auction and round robin algorithms in optimizing data rate, sum rate, spectral efficiency, power efficiency, and fairness. Specifically, the Greedy algorithm achieves an average data rate of 1.642 bps, an average sum rate rate of 1.218 bps, an average spectral efficiency of 3.046 bps/Hz, an average power efficiency of 1.650 bps/W, and an average fairness of 0.329, indicating its effectiveness in improving HetNet performance.]]>

<![CDATA[Waste is the residual product of human use that is often simply discarded and piled up, including organic household waste. The decomposition of organic waste causes unpleasant odors, environmental pollution, and becomes a breeding ground for disease-carrying animals. Therefore, composting is a necessary method that can be applied in households to manage organic waste with the aim of reducing and transforming it into beneficial products. In this modern era, a more efficient composting tool is needed, utilizing the Internet of Things (IoT) to monitor the composting process in real-time to produce compost that meets the Indonesian National Standard 19-7030-2004. This compost quality monitoring can be conducted both locally and remotely through a website integrated with the NodeMCU ESP32 microcontroller, which is connected to a Wi-Fi network to transmit data in real-time to a MySQL database for storage and management. Website testing at Wi-Fi distances of 5 meters and 10 meters from the device resulted in average response times of 31.943 ms and 31.444 ms, respectively, indicating that the website receives information with very good speed. 99.33% of all respondents agreed that the website met the friendly criteria in terms of both color and layout.]]>

<![CDATA[Enhancing internet accessibility on campus is vital for both academic purposes and general internet usage. This research aims to expand the outdoor WiFi coverage at Telkom University, taking into account wireless signal propagation, infrastructure, and network structure. The planning process includes conducting a walk test to evaluate signal coverage, simulating signal and interference, calculating the link budget (including pathloss, RSSI, and EIRP), and determining the Bill of Quantities (BoQ). The analysis of these simulations and calculations leads to informed planning recommendations. By applying the 4-C scenario approach, the study demonstrates that this method effectively covers the entire target area with a minimum RSSI of -75 dBm. There is no interference in the 2.4 GHz band, although co-channel interference occurs in the 5 GHz band. The RSSI consistently stays above -75 dBm, with the lowest measurement being -74 dBm over 200 meters in the 2.4 GHz band. EIRP values are within Indonesia's standard limit of 36 dBm, with a peak value of 33 dBm in the 5 GHz band. The total length of transmission cables used is 1628.3 meters, and the total BoQ amounts to Rp. 384,964,540.]]>
