Abstract

Soil color is the important due to its relation with other soil properties. It is usually analysis with the standard Munsell Soil Color Charts (MSCC). While other properties including organic matter need to be analyzed in the laboratory. The objective of this study is to develop IoT sensor for soil that is able to detect rapidly soil color and other properties including C-organic, pH, and cation exchange capacity (CEC). Soil color data from five soil type was analyzed using the MSCC and used as input data to the IoT (internet of things) sensor. In addition, soil properties obtained from lab tests was also included. The designed IoT sensor was used to detect soil color and soil properties of 7 soil types used as the testing samples. The sensor performance was evaluated by comparing soil properties predicted using IoT and lab analysis. Results showed the use of IoT soil sensor succeeded in determining soil characteristics including pH, CEC, and C-organic based on soil color. In addition, the soil color sensor had high accuracy to predict soil properties with a very small difference compared to the lab analysis, namely 0.01% difference for C-organic, and other properties of <5% difference. The development of IoT soil sensor will be important in the fields of agriculture and land management. Keywords: Acidity (pH), CEC, C-Organic, IoT, Soil Color.

Abstract

The biodiversity or diversity of macrofauna depends on abiotic environmental factors and biotic environmental factors. Macrofauna plays a role in decomposing organic matter so that it can restore and maintain soil productivity. The study aims to determine the diversity of soil macrofauna in the Complex Agroforestry system and its effect on the decomposition of coffee litter. The research was carried out by observation of soil macrofauna and observation of litter decomposition rate using RAK which was composed of 2 factors, namely the type of agroforestry and the difference in the age of coffee plants. The results showed that the macrofauna diversity of soil in Complex Agroforestry and Simple Agroforestry was not different because the amount of shade and diversity were almost the same. The Soil Macrofauna Diversity Index showed a low category (H' < 2) with an average INP value of 40 – 48%. Biotic factors (litter production) and abiotic factors (temperature and humidity) affect the diversity of good macrofauna. A high macrofaunaa population will affect the rate of decomposition of debris where macrofauna plays a role in remodeling organic matter.

Abstract

Land is an important part of the watershed because it is where the hydrological process occurs. There are several problems that can lead to land damage, especially in the downstream area of the watershed, precisely in the Manten Sub-watershed because it has the potential to become critical land. Therefore, this research was conducted with the aim to overcome the existing problems, it is necessary to identify the standard of land degradation in the Manten Sub-Watershed area in accordance with PP No. 150 of 2002. Manten sub-watershed covers 4 sub-districts namely Wajak, Poncokusumo, Tajinan, and Bululawang. Land use in Manten sub-watershed is divided into 3, namely rice fields, kailyards and fields. Based on the results of the analysis of all land use in Manten Sub Watershed, all parameters that have been observed do not exceed the critical threshold criteria except for the redox parameter has a very low value of <200mV. However, this condition can still be improved with proper management such as improving soil aeration using the addition of organic materials so as to increase oxygen levels in the soil and increase redox values.

Abstract

Soil erodibility is an important factor in determining soil loss. The objective of this study was to evaluate the soil erodibility value based on the Wischmeier-Smith Method. The study was carried out in Jatiarjo Village, Prigen District, Pasuruan Regency, at four land use units (LUU), including Mounts (MO), Mixed Garden (MI), Monoculture Garden (MG), and Shrubs (SR). Wischmeier-Smith algorithm was used to determine the erodibility values and classification. Results showed that shrub was identified as the land use with the highest potential for erosion and erodibility value. The correlation between clay fraction and erodibility has a negative value wit r = -0.76, while other fractions had r value < 0.5. This implied that the clay fraction and soil erodibility have an inverse relationship, where each increase in the clay fraction value will be followed by a decrease in the erodibility value. One way to reduce soil erodibility is to increase plant diversity on the land. Apart from adding organic matter, a variety of plants also have roots that are able to bind soil aggregates and help absorb water into the soil, thereby reducing water flow on the surface. If conservation is not taken seriously, it can undoubtedly result in.

Abstract

The early detection of Fusarium sp. infection in rice seeds is crucial for improving agricultural productivity and food security. Traditional methods like the Blotter Test, while effective, are time-consuming and require specialized personnel. This study explores the potential of thermal imaging technology to detect Fusarium sp. infections on rice seeds quickly and non-destructively. Rice seeds were inoculated with Fusarium sp. and incubated for seven days, during which surface temperatures were measured daily using the Fluke iSee TC01A thermal camera. The results showed that infected seeds exhibited significantly higher surface temperatures compared to control seeds, particularly from days 3 to 6 of incubation. Scatterplot analyses revealed clear temperature differences between infected and uninfected seeds, supporting the hypothesis that thermal imaging can serve as an early indicator of Fusarium infection. The study also demonstrated the high sensitivity and specificity of thermal imaging, particularly on days 2 to 4 of the incubation period. Logistic regression analysis confirmed the significant relationship between seed temperature and infection status, with prediction accuracy up to 91%. This research suggests that thermal imaging technology could replace traditional methods, offering a faster, more efficient approach for seed health monitoring in the agricultural industry.

Abstract

Land use changes significantly impact groundwater storage, which is crucial for maintaining ecosystem balance and supporting agriculture. This study aims to evaluate groundwater storage capacity across various land uses in the Gunting Sub-watershed, Wonosalam District, Jombang Regency, East Java. Field surveys and soil sampling were conducted across three land use types: pine-coffee agroforestry, pine monoculture, and annual crops at effective soil depths (0-60 cm). The study was conducted using a water balance method and lasted for one year, from August 2022 to July 2023. Water balance components consisting of effective rainfall, surface runoff, percolation, and evapotranspiration, as well as soil properties such as organic carbon content, porosity, and texture, were analyzed. The results showed that agroforestry had the highest water storage (370,863.44±176.67 mm/year), followed by pine monoculture (307,153.36±229.98 mm/year), and annual crops (239,497.30±222.26 mm/year). Statistical tests showed that differences between land uses were not significant (p > 0.05). Organic matter content was the dominant factor influencing soil water storage (R² = 0.9189), followed by porosity (R² = 0.3019) and clay fraction (R² = 0.0172). All land use types showed a positive water balance throughout the year, with peak water storage occurring in February–May.

Abstract

The Manten Sub-watershed faces land degradation problems due to improper land management. This study aims to identify the soil physical quality index across various land use types in the Manten Sub-watershed and to evaluate potential improvement alternatives. A descriptive quantitative method was applied by analyzing the Soil Physical Quality Index (SPQI) through the measurement of soil physical parameters such as bulk density, particle density, texture, structure, porosity, permeability, and soil organic carbon. Three land use types were evaluated in this research, including dryland or upland, rice field, and garden. Five sampling points were determined to score SPQI for each land use type. The results show that dryland farming and paddy fields can be classified as moderate to slightly good, with SPQI score values ranging from 0.57–0.73 and 0.63–0.70, respectively. Meanwhile, garden land use is classified as fairly good with SPQI score values of 0.70–0.73. Suggested improvement alternatives include the addition of organic matter and the implementation of soil conservation practices, such as proper tillage, cover cropping, and crop rotation.
