Sistem Pengukuran Cepat Unsur Hara Tanah dengan Integrasi Near Infrared Spectroscopy
Soil nutrient management is a crucial aspect of smart and sustainable agriculture. However, challenges in rapid nutrient measurement and accurate data management often hamper the effectiveness of agricultural practices. These limitations lead to the need for technological solutions that can improve the reliability and security of nutrient measurement data, which ultimately affects productivity and environmental sustainability. The main objective of this research is to develop an optimal system for soil nutrient data measurement and management. The research methods include: system design integrating near infrared spectroscopy (NIRS) and blockchain, prototype development of the system design, and testing and validation of the prototype to evaluate system performance both in experimental and field situations. The practical implications of this research are the contribution to the development of smart and sustainable agriculture, as well as increasing agricultural productivity through more

Abstract This study evaluates the efficacy of machine learning models for predicting soil nitrogen (N), phosphorus (P), and potassium (K) concentrations from near-infrared (NIR) spectral data (750–2499 nm). A comparative analysis was conducted on models from three distinct categories: linear-based, non-linear kernel-based, and neural network-based, using data from 145 soil samples collected across four Indonesian provinces. Regularised linear modelling performed best: Ridge Regression achieved R ²/MAE of 0.999/0.00005% for N-Total, 0.868/0.01408% for P-Total, and 0.763/0.01239% for K-Total. The non-linear SVR delivered moderate fit ( R ² = 0.821 for N-Total) but produced the lowest MAE for K (0.00829%) at lower explained variance ( R ² = 0.419). Neural network-based models underperformed the linear baselines. This study demonstrates that, for this dataset, a simpler regularised linear model outperformed more complex architectures, underscoring the critical role of rigorous model selection in developing accurate spectroscopic tools for precision agriculture. Future research could explore hybrid or ensemble methods to combine the strengths of different model types, potentially improving prediction accuracy and robustness.

Barium Strontium Titanate (Ba₀.₂Sr₀.₈TiO₃) thin films doped with carbon dots at varying concentrations (0%, 2%, 4%, and 6%) were successfully synthesized using the Chemical Solution Deposition (CSD) method. The films were deposited on p-type (100) silicon substrates via spin coating at 8000 rpm, followed by annealing at 850 °C for 8 hours. Structural characterization using X-ray Diffraction (XRD) confirmed a cubic lattice structure for all samples, with lattice parameters (a = b = c) measured as 3.306 Å, 3.324 Å, 3.336 Å, and 3.311 Å for the 0%, 2%, 4%, and 6% doping levels. The observed increase in lattice parameters with higher carbon dot concentrations is attributed to the larger ionic radius of carbon dots (10 Å) compared to Ti⁴⁺ (0.61 Å). These results indicate that carbon dot incorporation modulates the structural properties of Ba₀.₂Sr₀.₈TiO₃ films, which could have significant implications for their functional applications.

Abstract Sustainable agriculture is a system that aims to meet food needs while ensuring environmental health and social equity in the long term. One of the main challenges in sustainable agriculture is carbon pollution which can damage the nutritional quality of the soil. Carbon pollution from industrial, agricultural, transportation, and deforestation significantly affects soil quality globally. The concentration of carbon dioxide in the atmosphere and global warming can readily arise, leading to a decline in soil functionality and organic carbon levels within the soil. This issue is addressed through a bibliometric research approach to examine scientific publications on the effects of carbon emissions on soil nutrient quality within the framework of sustainable agriculture. The study aims to generate future insights and supply essential information for designing effective research methodologies and agricultural practices to mitigate the effects of carbon emissions on soil quality while advancing sustainable farming practices. The results of research studies conducted between 2020 and 2024, using geographical analysis, show that most of the contributions of studies in this field come from China, Spain, Italy, and India.

Abstract This study provides a detailed analysis of predicting soil nutrient content using spectral data and machine learning techniques in four Indonesian provinces: West Java, Central Java, Yogyakarta (DIY), and East Java. The research collected 145 soil samples to predict various key soil nutrients, such as N Total, NH4, NO3, P Total, P Available, K Total, K Available, C Organic, and pH. The study used linear regression (LR) and deep neural networks (DNN) with a deep cross-network (DCN) architecture to model the relationships between soil spectral data and nutrient content. LR was used as a baseline model to understand linear relationships between spectral features and soil properties and identify the most influential spectral frequencies in predicting soil nutrient levels. On the other hand, the DNN model captured complex, non-linear patterns within the data. Results showed that while the DNN model displayed advanced capabilities, the LR model generally outperformed it in predictive accuracy, particularly for nutrients like N-Total, P-Total, and K-Total. The findings highlight the potential of combining spectral data with advanced machine-learning techniques for precise soil nutrient estimation, which could significantly enhance agricultural productivity and soil management practices in Indonesia.

Abstract Sweat contains numerous biomarkers, including glucose, which can provide valuable insights into an individual’s metabolic state. Noninvasive glucose monitoring eliminates the need for frequent finger pricks or blood samples, offering greater convenience and reducing discomfort for individuals with diabetes. These biosensors are designed to detect and quantify glucose levels through various sensing mechanisms, such as enzymatic reactions or electrochemical measurements. The integration of biosensors into wearable devices, such as smartwatches, patches, or flexible electronics, allows for mobile glucose monitoring in sweat. Accurate glucose measurements require calibration and validation against reference measurements, such as blood glucose levels. Research focuses on developing calibration algorithms and improving the accuracy and reliability of mobile glucose biosensors in sweat.

Cardiac auscultation is the examination of the heart by listening to the sound produced by the heart through a stethoscope. Heart sounds can provide information about the functioning of the heart valve condition as well as information about the structural abnormalities of the heart. However, it needs intensive training for mastering. The objective of the work was to develop an algorithm for heart sound signal classification applied to computer-assisted digital auscultation in order to identify pathological events. The method can be described as follow: data collection, pre-processing, segmentation, feature extraction, and classification. The data were collected from volunteers using an electronic stethoscope and from a database available in the internet. The heart sound data were then extracted and split into training, validation, and testing datasets. In the training process the dataset was labeled as normal and abnormal (aortic stenosis, mitral stenosis, aortic regurgitation, pulmonic regurgitation, tricuspid stenosis, flow murmur, and patent ductus arteriosus). The convolution neural network is used as a classifier in the learning process to obtain the learning model. The model was validated and tested using the available datasets. The experimental results show that the algorithm has the capability to classify the heart sound into normal and abnormal with a high detection rate.
