Abstract

Rice is a staple food in Indonesia, with a high consumption rate of 81.044 kg per capita annually and a production volume of 31.54 million tons in 2022. Ensuring traceability in the rice supply chain is crucial for food quality and safety. However, the industry faces logistical challenges, such as inadequate infrastructure, poor interagency coordination, and unintegrated information systems. At Menata Citra Selaras (MCS), the largest rice milling unit in Bekasi Regency, manual systems hinder decision-making and product traceability. This study aims to optimize traceability by leveraging blockchain technology. We developed Ricetrack, a prototype application based on Sawtooth blockchain technology, to enhance supply chain traceability. The methodology includes identifying actors and user stories, system modeling, design, and prototype testing in an operational environment. Data analysis, both quantitative and qualitative, showed significant improvements in traceability and data transparency, validated through surveys and stakeholder feedback. The study concludes that blockchain technology offers substantial benefits for the rice supply chain, providing added value to all stakeholders and enhancing operational efficiency for MCS and other companies in the Indonesian rice industry.

Abstract

In Indonesian cuisine, the red Tabasco pepper holds a significant place as a commonly used ingredient. However, the cultivation of this chili variety is not without its challenges, primarily due to the volatile nature of the chili prices. Farmers often struggle with the critical decision of when to plant Tabasco peppers to optimize their yields and income. Understanding the complexities of this decision-making process in the context of varying environmental conditions is crucial. Thanks to recent advances in Internet of Things (IoT) technology, innovative systems have emerged to address these challenges.This study focuses on the development of an IoT-based solution aimed at helping farmers in precisely determining the optimal planting time for Tabasco pepper. It uses five key criteria—average temperature (°C), average humidity (%), rainfall (mm), length of sunlight (hours) and groundwater usage data (m3) to make data-driven planting decisions. The urgent need for such a system becomes evident when considering the unpredictability of climate patterns and their direct impact on crop outcomes. Using historical data from 2019, obtained from the Jakarta Provincial Government Open Data DKI, and climate data from the Meteorological Agency, Climatology, and Geophysics (BMKG), the authors have successfully developed an IoT-based prototype. This prototype employs a neural network algorithm to analyze the aforementioned criteria. The result is a reliable prediction system that boasts an impressive accuracy rate of 91.26%. By offering this level of precision in determining the ideal planting time for Tabasco pepper, the system extends invaluable support to farmers, helping them optimize their cultivation practices and navigate the uncertainties of the chili market.

Abstract

Evapotranspiration is defined as the loss of water from soil and vegetation to the atmosphere, driven by weather conditions. It reduces the availability of water for agricultural purposes, which affects the amount of irrigation water, particularly during the dry season. The objective of this paper is to present a comparative analysis of the estimated reference evapotranspiration value based on artificial neural networks (ANN) with backpropagation bias 1 (BP-1) and backpropagation bias 0 (BP-0) architectures. The model was fed with data of air temperature, relative humidity, and solar radiation. The model is utilized to calculate the evapotranspiration using the Hargreaves method as the training data. The performance of ANN model was evaluated using the mean square error (MSE), root mean square error (RMSE), and coefficient determination (R2). Our results showed that both ANN models performed well as indicated by low error (MSE < 0.01) and high R2 (>0.99). Also, we found that air temperature and relative humidity determine the optimal prediction. Further, this proposed model can serve as a reference for other models seeking to determine the most appropriate computational model for evapotranspiration value estimation.

Abstract

Cassava, an essential staple food with diverse applications, has been relatively underexplored in terms of health analysis using vegetation indices. Conventional field surveys face challenges in covering large areas due to resource constraints. Recent advancements in remote monitoring techniques, such as satellite imagery and Unmanned Aerial Vehicles (UAVs), offer a promising alternative. While satellite imagery enables broad-scale surveys, its limited spatial resolution restricts detailed analyses of individual plants or smaller ecosystems. UAV-based vegetation surveys commonly utilize Vegetation Indices (VI) to assess unique spectral information. This study investigated UAV-based methods for mapping cassava distribution in the Telaga Kahuripan smallholder plantation in Bogor, Indonesia, focusing on UAV imagery, segmentation, and vegetation indices to evaluate cassava plant health at 2, 5, and 8 months of age. The results revealed significant variations in vegetation indices across different cassava plant ages. Particularly, the highest values observed at 5 months of age indicated substantial growth, with NDVI and GNDVI values exhibiting R2 ranging from 0.95 to 0.98, indicating a strong correlation. The robust correlation between NDVI and GNDVI implies that both indices can effectively predict plant health using UAV-based monitoring. Comparisons with existing studies suggest potential variations attributable to factors such as geographical location, environmental conditions, and cultivation practices. Understanding these variations is crucial for refining monitoring techniques and informing agricultural practices. Consequently, the findings have implications for enhancing cassava health monitoring and optimizing agricultural practices to ensure sustainable crop production.

Abstract

Vehicular Ad-Hoc Network (VANET) merupakan pengembangan jaringan wiresless yang melakukan komunikasi secara Inter Vehicle Communication (IVC). VANET memiliki mobilitas yang tinggi untuk setiap node nya sehingga jaringan komunikasi jenis ini adalah jaringan yang bersifat sementara dikarenakan node bergerak di lintasan dengan arah dan kecepatan yang dinamis. Dengan demikian, pengiriman paket data dari node sumber ke node tujuan menggunakan VANET memerlukan beberapa teknik komunikasi. Teknik terbaru komunikasi VANET saat ini adalah menggunakan SDN (Software Defined Network) yang berbasis geographic (SDGR) sebagai control plane dalam mengontrol komunikasi ad-hoc antar node. Dalam membentuk topologi jaringan komunikasi, SDGR mencari nilai jalur terpendek antar node dan kepadatan node yang tinggi. Tujuan utama penelitian ini melakukan analisis konsep protokol perutean (routing protocol) SDGR dan dilakukan pengembangannya dengan mempertimbangkan arah rute (SDGR+R). Pada SDGR+R, penambahan basis arah rute menggunakan multicast. Selanjutnya, dilakukan perbandingan kinerja antara SDGR dan SDGR+R. Hasil simulasi menunjukkan SDGR+R memiliki kinerja lebih baik daripada SDGR dalam hal latency sebesar 1.88% dan packet delivery ratio (PDR) sebesar 8.12%. Perancangan protokol perutean SDGR+R menambah ide pengembangan teknologi pada VANET untuk masa mendatang. AbstractVehicular Ad-Hoc Network (VANET) is a wireless network developed for communication on Inter-Vehicle Communication (IVC). Each node in a VANET has high mobility so that this type of communication network is a temporary network because the node moves on the track with dynamic direction and speed. Thus, sending data packets from source node to destination node using VANET requires some communication techniques. The latest technology for VANET communication is to use SDN-based geographic-based SDN (SDGR) as a control plane in controlling Ad-hoc communication between nodes. In forming the communication network topology, SDGR looks for the shortest path value between nodes and high node density. The main objective of this research is to analyze the concept of SDGR routing protocol and to develop it, considering the direction of the route (SDGR+R). In SDGR + R, the addition of route base directions uses multicast. Next, we compare the performance between SDGR and SDGR+R. Simulation results show SDGR+R has better performance than SDGR in terms of latency of 1.88% and packet delivery ratio of 8.12%. The design of the SDGR+R routing protocol gives to the idea of technology development on VANET in the future.
