Flash flood led to high levels of water in the urban areas, causing many problems such as bridge collapse, building damage and the victim died. It is impossible to avoid risks of floods or prevent their occurrence, however, it is plausible to work on the reduction of their effects and to reduce the losses which they may cause. The objective of this paper is to generate a flash flood map in Suoh region, using satellite images, UAVs images and GIS tools. Analytical Hierarchical Process is used to determine the relative impact weight of flood causative factors to get a composite Flood Hazard Index (FHI). The causative factors in this study are flow accumulation (F), rainfall intensity (I), geology (G), land use (U), slope (S), and elevation (E). The presented methodology has been applied to an area in Suoh region, where recurring flood events have appeared. Initially, FIGUSE method resulted in an FHI and a corresponding flood map. A sensitivity analysis on the parameter’s values revealed some interesting information on the relative importance of each criterion, presented and commented in the discussion section.

Authors: Rahman M S D P , Zahara S , Nurjanah M.
Published: January 2020

A seismometer is an instruments used to record ground motion, such as caused by earthquakes. It has a high sensitivity to ground motion, including noise. It’s sensitivity to noise can result in unstable recording, even components damage, therefore calibration is very important to do. Calibration is an activity of comparing instruments with standard instruments ascertained to maintain the quality and quantity of data produced. One of the methods is shaking table that provides ground motion simulation as a seismometer input. This method moves the seismometer with up-down vertical translation. The goal of this study is to design and build a prototype seismometer calibrator using microcontroller-based shaking table method on TDV-23S (Short Period Seismometer with a frequency response of 1-50 Hz). The designed calibrator is divided into the drive (uses stepper motor) and data retrieval system (uses ADXL345 sensor) that used Arduino-Uno as the microcontroller. Instruments testing is done by comparing with BMKG standard calibrators. The comparison results show the difference in structural displacement, 2 mm for the designed instruments and 0.8 mm for the standard calibrator, with signal amplitude difference produced by the designed tool is greater than the standard calibrator.
A field survey for the rupture continuity of Palu-Koro fault after Donggala earthquake on September 28th, 2018
Authors: Abdullah A I , Abdullah
Published: January 2020

The 28 September Mw 7.5 Donggala earthquake has generated the fault trace now able to be seen using satellite image on Google Earth especially in the Palu western zone. However, a field survey must be conducted in order to discover the decisive rupture continuity direction since it inspected not the entire trace for outside Palu areas in contrast. The survey result shows this rupture crosses Sigi, Palu, Palu Bay, and Donggala about 156 km in south-north directed. Yet, some slipping parts experienced dip-slip as oblique fault besides sinistral strike-slip/left-lateral fault type as currently inferred. Moreover, the liquefaction-affected areas were only occurred in the fault border zone such as in South Dolo, Sigi; Balaroa, Palu; and some areas of Donggala. Besides, this event reinforces evidence that Palu-Koro fault trace is the geothermal system components referred to what was happened to the villages of Pulu and Mantikole, Sigi. In sum up, this fault can be categorized as a disaster when significantly active it can cause massive damage to buildings and other infrastructures above the rupture even though the left-right side did not experience the same severe damage, and fatalities struck down by collapsed debris.

Authors: Kurniawan M , Sismanto  , Rugayya S
Published: January 2020

Shallow intrusions of igneous rocks are often found in the Kalisonggo area and form a columnar joint. The presence of shallow intrusions of igneous rocks in the study area is closely related to Mount Mujil as an ancient volcanic system. This study aims to prove the existence of igneous intrusion and subsurface conditions using the geomagnetic method. First Horizontal Derivative (FHD) is used to determine the edge boundaries of the anomalous source of the rock’s magnetic field. Quantitative interpretation is done by using 2.5 D modeling to determine the distribution of igneous intrusion in the study area. The results of data processing show the total anomaly value in the study area has a range of values ranging from -400 nT to 600 nT. Whereas the local anomaly value that has been reduced to the equator has a range of values between 350 nT and the lowest -400 nT with a closed contour closure pattern between the high anomaly and the low anomaly. Based on the cross-section results of 2.5 D incision 1 and 2, there are 3 layers of rock in the presence of boulder lava andesite. The andesite lava has a susceptibility value of 0.00004 SI which penetrates the bedding above it. The top layer is soil with a susceptibility value of 0.00001 SI. The next layer is the andesite breccia rocks with a susceptibility value of 0.00003 SI. The third layer is sandstone with a susceptibility value of 0.000005 SI. The model shows that the andesitic lava lumps did not break through the basement, this is following Van Bemmelen’s opinion that igneous rock in Kalisonggo is an avalanche.

Published: January 2020

It has been designed and made a sonometer device that uses a microcontroller and LM567 frequency sensor module. The sound from the sonometer strings is detected by the module sensor. If the module sensor detects that the string sound frequency is the same as the tuning fork frequency, the microcontroller will display the word “Sesuai” on the monitor screen (LCD) which means the string frequency is equal to the tuning fork frequency. Conversely, if the frequency of the strings sound is not the same as the frequency of the tuning fork, the microcontroller will display the word “T Sesuai” which means the frequency of the strings is not the same as the tuning fork frequency. Compared to the conventional sonometer, this sonometer (the modified sonometer) produces more accurate frequency values. In this study, the maximum relative error of the modified sonometer is 0.30% while the maximum relative error of conventional sonometer is 10.86%.

Published: January 2020

This study aimed to investigate the effects of the direction and flow rate of air in the heat sink to the performance of the thermoelectric coolers (TEC). A ribbed heat sink is placed on the cold side of the TEC as a heat exchanger component in the Styrofoam cooler box, while a water block placed on the hot side of TEC, the temperature, and flow rate of coolant is maintained constant. Airflow on the heat sink in the cooling room has been varied by two different types of fan modes; blowing and sucking. Air velocity is also varied for both flow conditions. The investigation showed that the sucking mode of fan at the lowest speed of airflow would generate the lowest temperature of the cooler compared with the other combinations of fan modes and speed of airflows. Based on these results, showed that the fan mode and velocity of an airflow across the heat sink affect the thermoelectric performance.

The purpose of this study is to determine students’ perceptions of the learning process in schools affected by earthquakes and liquefaction that occurred on September 28, 2018, in Central Sulawesi. This descriptive study was carried out on July 25 s.d. August 3, 2019. The selected disaster-affected schools were SMP Negeri 10 Palu, MTs 3 Palu, and MTs Al Khairaat Biromaru. The respondents of this study were 30% of the total students in each of these schools. Where sequentially respondents from MTs Negeri 3 Kota Palu, SMPN 10 Palu, and MTs Al-Khairaat Biromaru were 90, 100 and 40 people. The data in this study were obtained through a questionnaire of perception with eight questions. Each question in the questionnaire has four alternative answers. From the results of the questionnaire analysis at the three schools, it was found that students stated the learning process was in the inadequate category. This is due to psychological factors, service, teacher quality as well as poor facilities and infrastructure after the natural disaster. Thus it can be said that natural disasters in the form of earthquakes and liquefaction that occur cause a decrease in the learning process at school when viewed from students’ perceptions.

Otus jolandae is an endemic owl species of Lombok island. The previous study suggested exploring the ecology-related aspects more deeply since this species had been just identified in 2013 but their recent status is nearly threatened. This study was conducted in Natural Tourism Park (NTP) of Kerandangan forest from July to September 2016. The field observation was carried out during the night to observe the owl occurrence in different plant species and different vegetation structure (seedling, sapling, pole, and tree). The results reveal the most widely used plant species is Dalbergia latifolia and then followed by Tectona grandis, Tamarindus indica, Samanea saman, Mangifera indica, Delonix regia, and Swietenia mahagoni respectively. Moreover, about 71.6% Otus jolandae occurs dominantly in the tree structure, followed by 28.4% of the pole structure, while no occurrence found in seedling and sapling structure. This indicates the adult and subadult vegetation act as a critical part for being a territory for Otus jolandae. Hence, addressing the deforestation problem and at the same time protecting the forest in a good shape with more pole and tree vegetation structure will keep Otus jolandae population from the extinction.

The article considers the implementation of the strategic grain production planning to provide the population with high-quality and safe food in the Russian markets, as well as to improve the standard of living. Various conditions of grain storage have been investigated. The analysis of flat-type granaries has been carried out and their shortcomings have been revealed. At the established higher wheat moisture the problems that contribute to the loss of weight and quality have been identified. Methods of moisture measurement for grain crops have been studied. During the study, the grain moisture index was measured using thermogravimetric, conductometric, dielcometric and microwave moisture measurement. The influence of the wheat «Favorit» and «Donskaya Elegia» moisture mass fraction on self-heating and grain contamination has been studied. These grain varieties were stored in a flat-type granary. A promising direction for the automated control scheming is the use of waveguide grain moisture sensors for technological operations which require a flat floor surface. The sensor design features and the conditions for their placement have been presented. The study have proved the need to create an automated humidity control scheme to ensure basic indicators of wheat quality. The paper proposes a scheme of water-wave sensors installation.

Authors: Melnik A F , Shumetov V G , Kondrashin B S , Mikhaylov M R
Published: January 2020

The publication is devoted to the development of a method for assessing the quality of wheat grain based on Harrington’s desirability function, which reflects the nonlinearity of the relationship between the quantitative values of quality indicators and the psychological perception of a person. As an empirical base, we used the results of studies on the protein content, gluten content and sedimentation index – Zeleny test of more than 40 varieties of winter wheat, zoned in the Oryol region, the main analysis tool was the factor analysis by the method of principal components. It is substantiated that the set of these wheat grain quality indicators can be described with one slight distortion by one main factor, along with particular desirability functions used to construct a generalized quality indicator with linguistic levels “very good”, “good”, “satisfactory”, “bad” and “very bad”. The calculation of the values of the main factor of wheat varieties, which are absent in the initial data array, is proposed using an approximate formula that takes into account the indicator that is most closely correlated with it - the protein content. The proposed methodology was tested on the example of assessing the influence of sowing dates on the productivity of winter wheat variety Moscow 39. Based on the results of the studies, it is recommended to use the Harrington’s transformation to evaluate particular indicators of the quality of wheat grain. It is also promising to use the method of principal components for the formation of a generalized function of desirability, when the weights of particular indicators are taken into account “automatically” by using the main component as a normalized variable, which comprehensively reflects the quality of wheat grain.

Trials were carried out in 2015-2019 on the field of the field crop department of the FSBI Crimean Agricultural Research Institute located in the central steppe zone of Crimea. The climate is moderately cold, semi-dry, continental, with large annual and daily temperature fluctuations. The average annual temperature is 15.1°C at 350-450 mm of precipitation per year. Meteorological conditions during the years of research differed from long-term average data on the amount of precipitation and temperature conditions: The Selyaninov hydrothermal coefficient (HTC) in 2016 was 0.82, in 2017 - 0.61, in 2018 - 0.23, in 2019 - 0.59. The agroclimatic potential of Crimea is suitable for cultivation of winter camelina on the peninsula, which increases the biodiversity of agrophytocenoses and get high-quality oil for various purposes. The optimal seeding dates for winter camelina in the Crimea is the period from September 30 to October 15, which produces the highest yield of 1.32-1.35 t/ha. However, a fairly wide calendar range gives a satisfactory crop yield. Favourable terms of soil moisture give the most optimal conditions for the winter camelina yield at a seeding rate of 8 million/ha. The fatty acid composition of the oil obtained from camelina grown in the Crimea indicates its suitability for various areas of the national economy.

According to the results of numerous researches carried out in the Russian Federation and abroad, it was found that microelements, at their skillful use, are an important factor in increasing crop yields and improving the quality of products. The aim of our research was to study the pepper plants pre-sowing seed treatment and foliar feeding with microelements influence on the growth, development and productivity of this crop. The experimental part of the work was carried out in the period of 2014 … 2016 in the conditions of the Volgograd region. Experiments on the study of microelements were carried out according to a scheme consisting of 3 options: application into soil; presowing seed treatment; foliar top dressing of plants. Chemically pure compounds of manganese sulphate, zinc sulphate, copper sulphate, ammonium molybdate, and boric acid were used as microelements. The use of microelements in the conditions of the dry steppe zone of the Nizhneje Pvolzhje region is an important agrotechnical method, contributing to the acceleration of growth, development, increase in yield and improve the quality of the pepper fruits. It is recommended to carry out pre-sowing seed treatment by 0.05% solutions of copper sulphate, boric acid and manganese sulphate, as a way to increase seed viability, accelerate yield and improve seedling quality. In order to increase the yield and improve the quality during the period of pepper budding, foliar top dressing should be carried out by 0.05% solutions of boric acid, ammonium molybdate. Due to its high efficiency, simplicity and availability, presowing seed treatment and foliar top dressing of plants by micro-elements will find wide application in vegetable production.

The aim of our research was to study the influence of Triticum aestivum L. cultivation technology by direct sowing in comparison with traditional technology using a complex microbiological preparation on growth and development, as well as the yield and quality of the products obtained by the most common field crop in Russia. Scientific research was conducted from 2015 to 2018. in stationary experience. Weed control was carried out by a combination of mechanical and chemical methods according to the traditional system and direct-sowing chemicals. With direct sowing technology, the Gherardi G117 seeder was used. According to the traditional system, the SZ-3.6 seeder was used. The studied crop rotations are typical for the region. The laying of experiments and conducting research is carried out in accordance with generally accepted methods of field experiments in agriculture and crop production. The spike length was 0.5 cm longer according to the traditional system. The number of grains from ten plants was 82 in the classical agricultural system and 27.0 more in the variant without processing the biological product. The grain weight of 10 plants according to the traditional farming system was 1.5 g more. The number of grains in one ear by the classical farming system was 3.4 units significantly higher than by the technology without tillage. Productivity for three years does not have a significant increase in the study of agricultural systems. The mass of 1000 grains on average for 2016–2018. was 3 grams more in direct sowing.

The aim of the study is histochemical identification of the components of protein-carbohydrate complex of wheat grains with selenium sources during germination. We formulated a hypothesis about the stimulating effect of 4.4-di [3 (5-methyldipirazolyl] selenid (DMDPS) on the biosynthesis of substances with a bactericidal effect, which include mucoid substances and glycoproteids in the composition of the components of the protein-carbohydrate complex. We confirm the hypothesis on histochemical identification of the components of the protein-carbohydrate complex of wheat grain during germination with sources of selenium. To identify acid mucopolysaccharides, transverse and longitudinal sections of the grain were stained with Alcian blue according to Steedman. Schiff-iodic acid revealed neutral glycoproteins and was clarified in xyllol. The sections were then placed into the balm and viewed in a Zeiss Axioscop 40 FX light microscope using a Levenhuk C 510 NG digital camera. To detect methionine, sections were stained with Schiff’s reagent; to identify cysteine (SH-groups), sections were treated with a 0.05% solution of 2.2-dioxy-6.6-dinaphthyl disulfide. The obtained images were analyzed using Photoshop CS 5 tools. Positive effect of wheat germination with DMDPA on the content of both neutral glycoproteids and mucopolysaccharides, with a direct correlation relationship, and on the content of methionine and cysteine was proved.

The methods of mathematical planning of the experiment determined that the optimal dosages in the formulation of bread powder from microalgae Dunaliella Salina are 5.0-10.0 % by weight of flour in the dough. As a result of applying the recipe of promising new plant additives the organoleptic quality (taste, odor, status crumb) and physical-chemical parameters of the finished products (specific volume and porosity of bread crumb) improves. Due to the increased content of protein substances, including essential amino acids, dietary fibers, vitamins, minerals the bread has increased nutritional and biological value and can be considered as a product of therapeutic and preventive purposes. The range of functional bakery products is also expanding.

Festulolium is the first artificially created Poaceae forage culture. The advantages of this crop are good regrow capacity, high content of sugars and good winter hardiness. The authors investigated biological features and seed productivity of new varieties of Festulolium of different morphotypes in the conditions of the forest-steppe of the Central Chernozem Region of Russia. The material for research included 6 Festulolium varieties (the Aelita, VIK-90, Viknel, Debut, Izumrudnyi, and Sinta) bred in the Russian plant breeding centers, included in the State Register of the Russian Federation and admitted for cultivation in the territory of the Central Chernozem Region by the State Commission for Cultivation. Field experiments were carried out according to conventional procedures adopted in seed production of perennial grasses. Due to phenological observations the authors define that the duration of the vegetation period of Festulolium depends on the variety and weather conditions during the vegetation season. According to the results of observations it can be noted that in order to form the yield of seeds, the grass stands of different years of vegetation require an average sum of temperatures of 1283-1816°C and 128-181 mm of total precipitation. The most early-ripening variety was the Sinta followed closely by the Izumrudnyi variety. In the second and subsequent years of vegetation the plants of these varieties began to grow earlier than the plants of other varieties in the spring and were the first to reach the stage of full seed maturation in 83-88 days. Such varieties as the Debut, Viknel, VIK-90 were defined as late-maturing; their seeds ripened in 96-102 days. The most intensive linear growth, the greatest plant leafiness, leaf area, net photosynthetic productivity, photosynthetic potential and subsequent seed yield of 735.5 kg was demonstrated by the Izumrudnyi variety. Seed yield of the Sinta variety was slightly less (695.9 kg) followed by the VIK-90, Viknel and Aelita varieties.
