Vegetation that may covers the soil surface affects the detection results of soil water content using radar system in plantation areas. Vegetation will influence the propagation mechanism of radar waves, therefore, a method to overcome this effect is needed. The method to compensate the effect of vegetation based on a transmission line model is then proposed in this paper. The transmission line model is used as the concept for transforming the measured reflection coefficient under the vegetation effect to the ground reflection coefficient value. Experiments were carried out by taking a case studies on tea plantations. The tea plant becomes a vegetation layer which its effect needs to be considered on the detection of soil water content. An ultra-wideband radar system with a frequency range of 500 MHz - 3 GHz is proposed in this study. The radar is integrated to hexacopter drone for scanning the tea plantation areas. The radar-drone system flight with a constant elevation from ground level. The experimental results show that the proposed method is able to improve the detection results of soil water content using radar with an accuracy of 96%.

| DUDI DARMAWAN, ABRAR, JESSICA PRAMESTI, SUPRIJANTO | Intelligence Business & Green Economy for Economic Sustainability | Feasibility Study of Magnetic Field Induction Tomography for Metal Powder Identification in the Soil | The magnetic field induction method is one of the non-destructive nondestructive test methods. In this study, a magnetic field induction method was tested for tomography to identify the distribution of metal powders in the soil. Measurements are made using two types of coils which act as transmitters and receivers respectively. Copper (Cu), manganese (Mn) and iron (Fe) metal powders, which are evenly distributed in the soil, are used as objects of identification with varying masses of mass. The response value of the measured potential in the receiver coil is analyzed by looking at the difference between each addition of powder mass variation. Based on measurements that have been made, copper sensitive powder at a mass addition of 30 grams with a changing range of 80-100 mV, manganese powder sensitive at 50 grams of mass addition of 200 mV and iron powder that has been sensitive at the beginning of the addition of 10 grams of mass. From the overall tests carried out, the type of iron powder (Fe) has a measurement sensitivity range and the biggest voltage value changes to the addition of powder mass variations. From these results, the obtained coil parameters can be used and arranged in a multi coil to identify the distribution of metal powders in the soil using the tomography method. | Paper Link |
| DUDI DARMAWAN, DOAN PERDANA, ABRAR, INDRA WAHYUDHIN FATHONA | Intelligence Business & Green Economy for Economic Sustainability | Investigating the Electrical Properties of Soil as an Indicator of the Content of the NPK Element in the Soil | This study aims to analyze the correlation between electrical properties of soil and NPK concentration in the soil. The conductivity and capacitance of soil with various NPK concentrations were measured. The main contribution in this study is to provide recommendations on the use of the corresponding electrical parameters for determining NPK levels in the soil. So far, the measurement of the electrical method generally uses the conductivity value for all conditions, even in wet and dry soil conditions. In fact, wet and dry soil conditions affect the conductivity. Therefore, other electrical parameters are needed that can correct the results of NPK measurements in the soil. Conductivity in relation to capacitance can show better measurement validity. In this study, the linearity of the relation between conductivity or capacitance to the addition of NPK levels in the soil was investigated. Soil samples were prepared by varying the mass concentrations of the elements N, P, and K separately. The conductivity and capacitance values for each NPK variation were measured and mapped. The results showed that the conductivity in dry soil conditions was more linear, with average coefficient of determination of the three elements being 0.81, compared to capacitance with a coefficient of determination of 0.72. Whereas the addition of water to the soil sample resulted in better sensitivity and linearity in the capacitance compared to the conductivity, with each average coefficient of determination being 0.55 and 0.34. These results provide alternative solutions using capacitance as an indicator for determination of NPK content in wet soil. The use of capacitance parameters combined with conductivity in determining NPK content in soil is a novelty contribution to this research and can be applied to the measurement technology in agriculture. | Paper Link |
| FILDHA RIDHIA | Intelligence Business & Green Economy for Economic Sustainability | A Method for Estimating Soil Water Content in The Presence of Vegetation Using FMCW Radar | In agriculture and plantations, soil water content significantly affects growth, productivity, and sustainability. Soil water content is important information for agriculture and plantation. Direct measurement of soil water content, such as the gravimetric method on large areas, requires time and cost. The remote sensing technology can potentially be applied for measuring a large area. Ground Penetrating Radar (GPR) has been studied to measure soil water content. However, the presence of vegetation can act as an obstacle and significantly influence the detection results. This influence can cause a decrease in the accuracy of the detection results. Therefore, the presence of vegetation needs to be considered in estimating the soil water content. This paper proposes an extraction method for estimating soil water content considering the presence of vegetation. The proposed method is applied for the Frequency Modulated Continuous Wave (FMCW) system employed as a radar system used in soil water content estimation. The theoretical and simulation analysis was conducted to investigate the proposed method. The results show that the proposed method overcomes the problem of vegetation in soil water content estimation. The accuracy improvement that obtains is about 4.248%. The proposed method also performs well in the low SNR condition. | Paper Link |

| HASANAH PUTRI, ATIK NOVIANTI, DADAN NUR RAMADAN | Intelligence Business & Green Economy for Economic Sustainability | Water Turbidity Alert System For IoT-Based Water Tank | Water has enormous benefits in daily life; quality and quantity maintained are required to be always ensured. In Indonesia, Bandung, many people keep clean water supplies in water tanks. The habit appeared as the result of their dependency on groundwater. However, some people also have already been connected to the government's water pipeline network, but they still need to have clean water tanks for prevention. The tanks need regular maintenances to ensure the stored water remains clean. When the tanks are rarely cleaned, moss appears, clogging the water pipe. The manual process of monitoring water conditions has several weaknesses, such as needing expert staff, taking more extended time, having a greater possibility of errors, and not presenting and neatly storing documentation. This paper aims to implement a water turbidity warning system in tanks and an IoT-based scheduling system for cleaning water tanks. The system will be implemented at several points of the house or water tank and can transmit data in real-time either alternately or simultaneously. The sensor detects water turbidity, and the microprocessor control unit node is in charge of processing the sensor reading data to calibrate and classify the turbidity level. Water turbidity values and levels are sent to Firebase, which resides in the cloud. The information from Firebase is passed and displayed on the application. The turbidity level of water was categorized into three: clean, turbid, and dirty. Managers, as the service providers, and consumers can monitor the tank's condition with a warning in the form of an indicator when the tank must be cleaned. | Paper Link |
| ISMAN KURNIAWAN | Intelligence Business & Green Economy for Economic Sustainability | Implementation of Machine Learning Methods for Monitoring and Predicting Water Quality Parameters | The importance of good water quality for human use and consumption can never be underestimated, and its quality is determined through effective monitoring of the water quality index. Different approaches have been employed in the treatment and monitoring of water quality parameters (WQP). Presently, water quality is carried out through laboratory experiments, which requires costly reagents, skilled labor, and consumes time. Thereby making it necessary to search for an alternative method. Recently, machine learning tools have been successfully implemented in the monitoring, estimation, and predictions of river water quality index to provide an alternative solution to the limitations of laboratory analytical methods. In this study, the potentials of one of the machine learning tools (artificial neural network) were explored in the predictions and estimation of the Kelantan River basin. Water quality data collected from the 14 stations of the River basin was used for modeling and predicting (WQP). As for WQP analysis, the results obtained from this study show that the best prediction was obtained from the prediction of pH. The low kurtosis values of pH indicate that the appearance of outliers give a negative impact on the performance. As for WQP analysis for each station, we found that the WQP prediction in station 1, 2, and 3 give the good results. This is related to the available data of those stations that are more than the available data in other stations, except station 8. | Paper Link |

| RIZKI ARDIANTO PRIRAMADHI, CANDRA ADI SISHANANTO, MUHAMMAD ARY MURTI | Intelligence Business & Green Economy for Economic Sustainability | ARDUINO-BASED SOIL STRUCTURE DETECTOR USING GEOPHONE | Because of technology development, the needs for energy are increasing. Earth provide energy source by means of oil, gas and coal, buried beneath ground soil. A tool that can detect soil structure and material before drilling is needed. Each material has a different density; the difference in density produces a back effect. Geophones can be used to detect differences in material that is below the surface of the ground. This is done by carrying out artificial vibrations and receiving these vibrations with the geophone. To measure the vibrations that will be captured by the geophone, it begins by arranging the geophone configuration to be placed in a straight line with the wave source. The data obtained from the survey is the wave travel time from the source to each geophone indicated in the wave traces. This research concludes that a geophone sensor that can read the speed of waves in passing through stone, split stone and sand. Each medium produces a different speed - the denser the density of the medium, the faster the velocity of the wave propagation through it. In this final project the fastest is split stone with 1.62ms, brick is slightly slower with 4.02ms, and sand is the slowest with 15.86ms. | Paper Link |
| SARAH MAHARANI, BANDIYAH SRI APRILLIA, PORMAN PANGARIBUAN, ANANDA AYU AULIA | Intelligence Business & Green Economy for Economic Sustainability | DESIGN AND IMPLEMENTATION OF AUTOMATIC SOLAR WATER PUMPS FOR IRRIGATION | Irrigation of rice fields can be done easily during the rainy season by utilizing irrigation water routes. During the dry season, farmers oftentimes use groundwater for irrigation. Water pumps that are commonly used when taking groundwater are typically powered by diesel or electrical grid from PLN. However, the long distance between energy sources and water pumps for irrigating rice fields is one of the obstacles in Mauk Village. Therefore, this study aims to design and implement a solar powered water pump for irrigation. Based on the research results, the 50 WP solar powered water pump can operate in sunny, overcast, and cloudy weather. The low intensity of solar radiation on cloudy days causes the irrigation time to be longer than sunny days. This is because the power output of the off grid solar power system is strongly influenced by the test weather conditions. In sunny conditions, the highest power resulted was 33.01 Watt, while in cloudy and overcast conditions the maximum power obtained was only 27.60 Watt and 24.34 Watt respectively. The output power of the solar panel also affects the amount of battery SOC that can be charged, the greater the power generated, the higher the percentage of the battery SOC. In addition, the cost savings for solar powered pumps equal to more than 90% compared to diesel water pumps. | Paper Link |
