Abstract

Fish cultivation has a high potential to improve the welfare of the community. One of the important factors influencing the success of fish cultivation is the aspect of water quality in the pond which is illustrated by several physical parameters such as temperature, degree of acidity (pH) and turbidity of the water. The use of water for cultivation must always be maintained at turbidity level, the impact of turbid water causes disruption to the physical growth of the fish and even death. Due to the limitations of humans who cannot monitor ponds 24 hours, a system is created that can monitor and control water quality in real time. To get good water quality for cultivation, the authors make this system using a turbidity sensor to detect water turbidity, a pH sensor to detect the acidity of the water and a temperature sensor to detect the temperature of the water on the pond. While processing and control using a microcontroller, namely NodeMCU. Periodically the sensor will send the measurement results to the Cayenne application in real time which can be viewed via a smartphone / PC. The control system is also made with two modes, namely automatic and manual modes to fill and drain water on the pond. Based on the results of system testing, turbidity, pH and temperature sensors are very good in detecting any changes in pond water conditions. Cayenne application with IoT technology is able to provide action on the water pump in the process of draining and filling water in ponds with manual mode. NodeMCU is able to send data with a good internet connection.

Abstract

In recent times, the supply chain has developed into a large ecosystem. Various products moving from party to party require cooperation between stakeholders in managing the data generated. The problem is that every company has its own transaction records that can be inconsistent and their storage is centralized and not integrated between companies. This makes transaction records easy to falsify. Efficient data management is needed from the producer to the store so that consumers can trust the product. Therefore, the authors designed a product tracking system using blockchain by implementing proof of work (PoW) as the consensus algorithm, SHA-3 256 as data security, Mongo database as cloud-based data storage and QR Code as the output. As a result, transaction data from producers, distributors to retail stores are stored completely in MongoDB which is a cloud-based database, then the resulting QR Code can be used to view details of producers, distributors to retail stores that sell them. The simulation and trial results show the product tracing system design is successful as expected.

Abstract

Plants are essential to human beings because plants are considered most as foods. Plants can be used for food ingredients, medical purposes, and industrial applications. People inspect plants using traditional methods, such as using the naked eye, which can be time-consuming and expensive. Therefore, the effectiveness and high quality of automated crop identification classification systems are needed for adequate crop protection. This study aims to identify and classify nine plant species using different datasets, focusing on transfer learning from models trained on plant leaf datasets. Most research has shown that increasing the dataset size would significantly improve classification accuracy. The accuracy of the first test using the modified N1 classification model was 99.45%. In the second experiment, the accuracy of the N2 model was 99.65%. The accuracy of the N3 model, despite being slightly less accurate than AlexNet, was 99.55%, and it performed better, while the accuracy of AlexNet was 99.73%. Compared to the AlexNet model, the proposed model performed better and required less training time. The N1 model reduced the training time by 34.58%, the N2 model by 18.25%, and the N3 model by 20.23%. The N1 and N3 resulted in the same size, namely 14.8MB, and the compactness was 92.67%. The size of the N2 model was 29.7MB, and the compactness was 85.29% compactness. The proposed models provide more accuracy and efficiency in classifying plant leaves and can be used as a standalone mobile application that benefits farmers.
