Computational technology for improving the quality of difference schemes based on moving nodes
Authors: Rasulov Abdujabar , Dalabaev Umurdin 
Published: April 2021

Abstract
In our papers by us [11],[12] a new method of moving nodes (MMN) was introduced to obtain an approximate analytical solution and construct compact schemes for a one-dimensional convective-diffusion problem. It is proposed to improve the scheme in a three-point pattern. As an initial scheme, a counter flow with one-sided differences is taken. In the QUICK scheme [5], quadratic up flow interpolation is used to determine convective flow. Here we use the solution obtained by the upwind scheme based on MMN. In our above works, the improvement in the accuracy of difference schemes was obtained on the basis of using the method of multi point MMN. In this work, it is proposed to improve the accuracy of the constructed difference schemes using the three point MMN. This is achieved using a more accurate solution to the unknown function on the edge of the considered control volume, the algorithm of which is described in detail in this work.

Authors: Hasan A Alhaj , Zhechev Y S , Gazizov T R 
Published: April 2021

Abstract
The paper presents the electrodynamic simulation results for radiated emisions. The authors consider structures with and without a single modal reservation in the frequency range from 0.1 to 10 GHz. Frequency dependences of the electric field strength and radiated power were obtained. Radiation patterns at frequencies of 0.5, 5, and 10 GHz are presented. The authors showed that due to the strong electromagnetic coupling between the reserved and reserving circuits in inhomogeneous dielectric filling, the radiated interference is lower for the structure with a single modal reservation than without it in almost the entire frequency range under study.

Published: April 2021

Abstract
Cassava is a staple food source of carbohydrates, which is consumed in various forms such as growol, gatot and tiwul. Growol is produced through a fermentation process and therefore, has a sour taste typical. As an intermediate moisture food, it has a shelf life of just 3-4 days and is susceptible to mold growth. Previous studies have shown that a drying process may extend its shelf life to more than 6 months. The problem in carrying out this process was that growol producers in rural industries always make use of a mixture of several cassava varieties and fermentation was carried out for 2-3 days. Due to this reason, its physical and chemical properties varied. This study aims to evaluate the effect of the cassava variety and fermentation time on the texture and acceptability of cooked-dried growol. This research used three cassava varieties i.e. Meni, Ketan, Lanting and the fermentation time was 2 and 4 days. The fresh cassavas and dried-growols were analyzed for their starch, amylose and moisture content. Furthermore, the acceptability was determined by cooking each dried-growol using a rice cooker and its ratio to water was 1:2. Afterwards, they were tested for texture and preference level through a hedonic test. The results showed that the starch content of cassavas and their acceptability were significantly different, whereas the texture of cooked-dried growol was not significantly different The acceptable was produced with Meni cassava variety and fermentation time of 2 days.

Abstract
Indonesia is one of the largest coffee producer and exporter countries in the world. The current significant environmental problem challenge being faced by Indonesian farmer is the absence of utilization of coffee by-products. Coffee processing from fruit to brewing coffee that is ready to drink produces a large amount of by-product. Depending on the processing method chosen, the waste produced also differs consisting of pulp, husk, musilage, silver skin and residual coffee grounds. This review aims to provide an overview on coffee by-products characteristic and their potential utilization as profitable products. For this purpose, we have collected and reviewed some literature on chemical properties of coffee by-products and the history of these by-products consumption in some countries. The coffee pulp is the largest by-product acquired during wet coffee processing, so the primary attention has given to the by-product. The by-products have been studied from the coffee pulp including juice, cascara and kombucha. Cascara is a tea made from dried coffee pulp. Cascara has a long history of consumption in Yemen, Ethiopia and South America with different name. Other products are still being studied as products with great potential for further development. With the high crop production projected in the future, the utilization of coffee by-products as useful products should be realized. It is hoped that the results of this review can provide insight to all stakeholders.

Abstract
National mushroom production in 2018, 2017, 2016 and 2015 amounted to: 31052, 3702, 40915 and 33485 tons. In 2018 the per capita availability is 0.15, this figure needs to be increased as an alternative food solution, this is based on the texture of mushrooms that resembles meat and is delicious, making this plant often become a variety of processed foods such as chips, rendang, satay, shredded, meatballs and supplement. Mushrooms cultivated in Indonesia have high nutritional value and even mushrooms contain 19-35 percent higher protein than rice (7.38 percent) and wheat (13.2 percent). Cultivation of mushrooms, especially oyster mushrooms, has the potential to be developed more widely in Indonesia because it has economic value and is environmentally friendly. However, oyster mushroom cultivation has challenges, especially to produce maximum production in each kumbung. The challenge that arises in oyster mushroom cultivation is that it grows well at temperatures of 16-30 ° C and relative humidity of 80 - 95%. Environmental conditioning is carried out by the average farmer by manually spraying water in the mushroom kumbung. The use of manual methods requires high human resources, apart from that it is not effective and efficient. This study aims to develop a Temperature and Humidity Control System in Kumbung using a Fuzzy Logic Controller. This research uses Fuzzy Proportional-Integral-Derivative (PID) Controller, the sensor data (Temperature and Humidity) will be processed as a sensor array, where to determine the temperature and humidity the system will evaluate the readings of several sensors at once. The system developed is an adaptive system using the Fuzzy method which will suit the environment, the test results show an accuracy rate of 86%, so it is expected that the configuration generated by the tool can be used to increase the precision of mushroom cultivation, so that production efficiency and increased mushroom production can be achieved.
