Abstract

Nitrogen ion implantation at 50 keV of energy on the surface of SS 316 stainless steel, by calculation will only be able to reach a depth of 561 Å and the ions will be distributed Gaussian effectively at a depth of 561 Å ± 339 Å, so that from the surface to a depth of 222 Å is not filled by ions (empty) which of course will affect the properties of the implanted surface. The solution to the problem is to implant the target several times at <50 keV of energy. To minimize the un-filled volume, the study of simulation and calculation has been conducted. In this study a simulation using TRIM program to know how many times the target should be implanted at different energies and also the calculation of the amount of nitrogen ions that should be implanted, so that the distribution of nitrogen ions can be evenly distributed from the surface to 561 Å. From the results of simulations and calculations the results show that the target must be implanted at least 6 times implantation at energy 50 keV,40 keV, 30 keV, 20 keV and 10 keV. Under these conditions the dose that must be implanted are 7,4×1017ion/cm2, 6,44×1017ion/cm2, 4,6×1017 ion/cm2, 3×1017 ion/cm2 and 1,6×1017 ion/cm2. The total doses and amount of nitrogen filling the implanted volume are 7,32%..

Abstract

Smart technology has provided many benefits for all human activities, including hydroponic farming systems. The consistent challenge in the process of cultivating plants using hydroponic systems is the monitoring of partner farmers in managing plant nutrition. Smart technology, utilizing microcontrollers and multisensors, can enhance hydroponic management, particularly concerning the control of nutrient availability, including saturation, water pH, and water availability in the hydroponic system. The purpose of this activity is to address partner-related issues regarding their lack of knowledge and skills in managing businesses aided by smart technology such as microcontrollers and multisensors and to improve the economic viability of partner businesses by producing nutritious and high-quality vegetables. The method used in this community engagement activity involves initial observation at the partner's business location, theoretical instruction to enhance partner knowledge, and finally, training in the creation and operation of smart technology involving microcontrollers and multisensors in the partner's hydroponic area. Questionnaires were distributed to assess the initial conditions before the training and to measure the success of the training after its completion. The initial observation showed a lack of knowledge about smart technology using microcontrollers and multisensors. Based on this, theoretical training was conducted to improve partner knowledge about smart technology using microcontrollers and multisensors. The theoretical content included 1) technology and innovation in hydroponic plant nutrition, 2) an introduction to microcontrollers and sensors in agriculture/horticulture technology, and 3) a demonstration of monitoring physical parameters and nutrient content of hydroponic plants using the Wokwi simulator. Subsequently, a simulation of microcontroller and multisensory device use was carried out, resulting in an enhancement of partner skills in using microcontrollers and multisensors. The improvement in partner knowledge and skills after participating in this training is evident from the questionnaire results, and partner satisfaction with the conducted training is also evident. The conclusion of this community engagement activity is that partners have gained knowledge and skills after participating in the training on the application of smart technology for microcontroller-based irrigation of hydroponic plants with multisensor systems in hydroponic plant cultivation.

Abstract

The moisture content of seaweed during the drying process is one of the factors determining the quality of seaweed. Therefore, measuring the percentage of water content in seaweed during the drying process is very important to note. A multilayer capacitive sensor for water content detection application in seaweed drying process using the Fast Fourier Transform (FFT) algorithm has been successfully built and characterized. The sensor is made from a Cu PCB substrate in the form of a potential ladder pattern with dimensions of 5 x 5 cm. The PCB substrate is then coated with several layers of NiFe and Cu forming layers using electro deposition technique. The research method consists of making the sensor, calibrating the sensor using the gravimetric method, and performing two measurement schemes, namely measuring changes in the ADC value of the sensor as a representation of the seaweed moisture content value and measuring changes in the frequency value of the sensor as a representation of the moisture content value using FFT algorithm. The results showed that the sensor characteristics in the form of sensor slope of 18.866 ADC value / (%) water content with an intercept of 68.248 ADC value. So that the sensor will experience a decrease in ADC value changes by 18.866 every 1% increase or decrease in water content. For the coefficient of determination R2 of 0.91618 which indicates that the sensor has approached the reading of the water content value with good precision. Based on the measurement results of the seaweed water content value also shows that by using FFT algorithm, the reading of the seaweed water content value can be represented by the frequency value of the sensor well. This research contributes to the development of innovative sensor technology in measuring moisture content during the seaweed drying process.
