Abstract

The fermentation process of cocoa beans is a critical stage in chocolate production that affects the final quality of the product. To ensure that fermentation takes place optimally, monitoring parameters such as temperature, humidity, and pH is necessary. This research aims to develop and validate an Internet of Things (IoT)-based data acquisition system that uses ESP32 and MQTT protocols to monitor the fermentation process of cocoa beans. The system consists of an ESP32 module connected to DHT22 sensors to measure temperature and humidity, and a pH meter to measure acidity. The data collected by the sensors is sent in real-time via a wireless connection to an MQTT broker, where it can be monitored continuously. System testing was conducted in a small-scale fermentation environment. Validation results show that the system is capable of providing accurate and consistent data when compared to manual measurements using standardized tools. The difference between the data collected by the system and manual measurements was within acceptable tolerance limits, indicating that the system is reliable enough to be used in small-scale applications. The system also demonstrated fast response to changes in fermentation conditions, and stable data connection with minimal latency via the MQTT protocol. The developed data acquisition system has successfully acquired data and validated it using standard measuring instruments. The average data error for the pH sensor is 2.78%, temperature sensor 1.41%, and humidity sensor 1.94%. These error values indicate that the performance of the sensors used is good.

Abstract

In today’s digital era, reliable and fast connectivity has become an important need for many people Long Term Evolution is a standard for high-speed wireless data communication for mobile phones and other data devices. This study aims to analyze the Key Performance Indicator of the LTE Indoor Network at Mall Mtos Makassar. The mall Mtos Makassar building is a shopping center, a place to watch, a place to play, etc. The Mall Mtos building has 3 large and complex floors. This measurement was carried out with 3 telecommunications operators, namely Telkomsel, Indosat Oredoo, and Xl Axiata. The parameters analyzed include Reference Signal Received Power, Reference Signal Received Quality, Signal to Interface Noise Ratio, Received Signal Strength Indicator, and Throughput Uplink Downlink. The research method used includes the walk test method with 3 floors of Mall Mtos Makassar with Idle and Dedicated mode measurements. The result of the analysis on measurement from the 1st to 3rd floors shows the signal performance between operators, thus the Telkomsel Operator shows a relatively better performance compared to the Indosat Oredoo and Xl Axiata Operators.

Abstract

Indonesia's economic growth in the logistics sector is becoming increasingly significant, alongside the rising demand for goods. However, the complexity of logistics supply chain management in Indonesia still faces challenges, including security, human error, and lack of transparency. This research proposes the use of blockchain technology for a logistics supply chain management system, which is capable of storing transaction data in a decentralized and distributed manner. Ganache is used as a local blockchain server, Metamask for transactions, and smart contracts to manage user flows on a web3 dapps-based website. The research procedure includes literature study, design, development, and system testing. The test results indicate that all features and functions of the system operate as expected. The system not only successfully handles high demand and transaction spikes but also demonstrates enhanced data security, improved transparency through real-time tracking, and robust performance under high workloads. Overall, this blockchain-based logistics supply chain management system effectively secures and manages transaction data while enabling data tracking and tracing, thereby increasing transparency and handling high concurrent transactions efficiently.

Abstract

Jeneponto Regency in South Sulawesi possesses significant wind potential, making it an ideal location for the development of Wind Power Plants (WPP). However, these WPPs are intermittent due to the inconsistent nature of wind energy, presenting challenges that affect the performance and efficiency of turbines in generating electricity. Therefore, this study aims to evaluate the performance of the SWT-3.6-130 wind turbines at the Tolo 1 WPP in Jeneponto to determine their capability in converting wind energy into electrical energy at specific wind speeds. The evaluation results indicate that the performance of the SWT-3.6-130 wind turbines at the Tolo WPP in February 2022 was not optimal. The maximum output power generated by these turbines approached the maximum capacity of 3.6 MW, with Turbine 06 producing 3.57 MW at a wind speed of 13.07 m/s, Turbine 09 producing 3.57 MW at a wind speed of 12.27 m/s, and Turbine 013 producing 3.58 MW at a wind speed of 12.11 m/s. Although the power generated was close to the maximum capacity, the performance variation among turbines indicates the need for further evaluation to address factors reducing efficiency. Power coefficient analysis shows that Turbine T13 exhibited the best performance, with the fewest instances of power coefficient values not meeting standards. This study provides crucial insights for improving performance and preventing failures at the Tolo WPP in the future.

Abstract

Agriculture is a key sector of the Indonesian economy, with shallots being one of the most important commodities. However, limited access to electricity in rural areas is often a barrier to the implementation of efficient irrigation systems. This research focuses on developing an automatic shallot irrigation system using a solar pump. The system is designed by using solar panels to convert solar energy into electricity to power the water pump. They use an Arduino-based control system integrated with a real-time clock (RTC) to automatically set the watering schedule so that plants can be watered at the right time without human intervention. Tests were conducted on 96 m² of land to evaluate the performance of the automation system, energy efficiency, and system performance under actual operating conditions. The testing results show that the system can operate efficiently, with the solar panel generating enough energy to power the pump and maintain watering continuity. The system can reduce dependence on conventional electricity, providing a sustainable and environmentally friendly irrigation solution. As such, the system provides an effective solution for agricultural systems in areas with limited access to electricity, while supporting the use of renewable energy.
