Published: October 2021

This work characterizes ancient mortars used in construction of the Bronze Age Minoan port at Kommos in Crete. The port dates from c. 1850 BCE with port facilities at the harbor and residences on the Central hillside and the Hilltop. A Greek, Phoenician, and Roman sanctuary overlies the administrative center. The first step collected representative samples from the different construction phases, previous conservation interventions, exposure to different environmental factors, and different material composition. From these 10 mortar samples were analyzed using stereo- and digital microscopy, X-ray diffraction (XRD), X-ray Fluorescence (XRF), and Fourier Transform Infrared spectroscopy (FTIR) to determine texture, morphology, mineralogical, and physico-chemical properties. The physico-chemical and mineralogical analyses divided the samples into two groups: lime binder mortars and earthen binder mortars. The main minerals identified in the samples are calcite, quartz, dolomite, illite, albite, kaolinite, and vermiculite. Analysis of local clay showed that local materials were used in the production of these mortars. The analysis of mortar samples with stereomicroscopy, XRF, and FTIR showed that the samples are mainly composed of calcite and silicates in major quantities along with aluminum, magnesium, and iron oxide in minor quantities. A wide variety of local aggregates and ceramic fragments were used in the production of these ancient mortars. The mortar condition resulted in a decay state that needs conservation interventions. This characterization of the ancient mortars was important for the design of compatible restoration mortars.
Context-Aware Sensor Uncertainty Estimation for Autonomous Vehicles
Authors: Alharbi Mohammed , Karimi Hassan A.
Published: October 2021

Sensor uncertainty significantly affects the performance of autonomous vehicles (AVs). Sensor uncertainty is predominantly linked to sensor specifications, and because sensor behaviors change dynamically, the machine learning approach is not suitable for learning them. This paper presents a novel learning approach for predicting sensor performance in challenging environments. The design of our approach incorporates both epistemic uncertainties, which are related to the lack of knowledge, and aleatoric uncertainties, which are related to the stochastic nature of the data acquisition process. The proposed approach combines a state-based model with a predictive model, where the former estimates the uncertainty in the current environment and the latter finds the correlations between the source of the uncertainty and its environmental characteristics. The proposed approach has been evaluated on real data to predict the uncertainties associated with global navigation satellite systems (GNSSs), showing that our approach can predict sensor uncertainty with high confidence.

Published: October 2021

Effects of nano-selenium (nano-Se) and stocking density (SD) on growth performance, carcass yield, meat quality, and feathering score of broilers were investigated in this study. One-day-old 480 broiler chickens (45.32.4 g body weight) (Ross 308) were randomly divided into 4 treatments each comprising of 8 replicates. In the experiment, treatments consisted of a 2  2 factorial arrangement of dietary Se form (inorganic or nano) and SD (low = 12 birds/m2; LSD, and high = 18 birds/m2; HSD). No interaction was noted between Se form and SD for any trait. Nano-Se had no effect on growth performance, however, HSD decreased the body weight gain (BWG) (P0.05) and feed intake (FI) (P0.001) while feed conversion ratio (FCR) was unaffected. Neither nano-Se nor HSD had any effect on the relative carcass, breast, and thigh yields. Nano-Se improved the water-holding capacity (WHC) of breast meat 72-hpost-mortem (P0.05). However, pH, colour, and cooking loss of meat remained unaffected by Se form or SD. There were no differences between nano- or inorganic Se and LSD or HSD regarding feathering scores for back and wing. In conclusion, dietary nano-Se improved the WHC and had no significant effect on other parameters. In addition, HSD may negatively affect the growth performance.

Authors: AŞTI Ceren , ÖGE Hatice
Published: October 2021

Visceral Larvae Migrans (VLM) is a syndrome in humans, caused by Toxocara canis larvae. A current and completely successful treatment protocol against such a common infection has yet to be established. In this study, the effect of combination of albendazole and N. sativa oil for the treatment of VLM was investigated. Five experimental groups were constituted and a total of 125 Swiss albino (male, 6-8 weeks old) mice were used. All mice in each group were infected with 750 T. canis eggs with infective larvae, except the negative control group. 100 mg/kg albendazole and 0.15 ml Nigella sativa oil were applied orally to groups ALB and NSO separately and given orally to group COM in combination. The efficacy of the treatment was investigated parasitologically, histo-pathologically, and hematologically on the 7th, 14th, 28th, 45th, and 60th days post-infection with necropsies. The larval recovery analyses revealed that, the highest treatment efficacy was obtained in group of combination. The treatment efficacy was 72.46%, 48.81%, 36.25% in the groups of COM, ALB, and NSO, respectively. The most severe pathological changes were developed in Group ALB, and the inflammatory reactions and pathological changes in Groups of COM and NSO were mild. We conclude that N. sativa oil enhances the larvicidal effect of albendazole by having an anti-inflammatory effect and increasing tissue defense and immunity.

Published: October 2021

Pulmonary veno-occlusive disease (PVOD) is an uncommon disease in humans and animals caused by pulmonary hypertension (PH). The aim of this study was to investigate pathomorphological findings of PVOD in a cat. A mass was detected in the right atrium with echocardiography in an 11-year-old male cat. Following treatments, necropsy of the cat was performed after death due to respiratory failure. Macroscopically, masses were detected in mesenteric lymph node, mediastinal lymph node and, heart. Congestion and consolidated areas with edema were seen in the examination of the lung. Histopathologically, neoplastic lymphoid cells were observed in intestine, lymph nodes and heart. In lung, vein lumens were almost completely occluded by mostly loose intimal fibrosis. Near affected veins, increasing in number of the capillaries was observed. While intimal fibrosis was detected by Masson’s trichrome staining, the occluded veins were demonstrated by Verhoeff-van Gieson staining. In this case report, pathomorphological evaluation of PVOD was performed and as a result of clinicopathological examinations; PVOD, intestinal lymphoma, and cardiac metastasis were described in a male cat.
migrações na África antiga
Authors: Diouf Benjamin
Published: October 2021

Na África, durante a Antiguidade, populações migravam por razões políticas, econômicas e naturais. O continente havia igualmente acolhido vários estrangeiros que haviam deixado seus países pelas mesmas razões. Essas migrações tiveram impactos sobre as relações entre os povos autóctones e os migrantes. Hoje, torna-se importante revisitar este passado migratório da África para melhor compreender os problemas dos migrantes no continente.
A educação como kairós em Os Trabalhos e os Dias
Authors: Cecilia Colombani María
Published: October 2021

Este artigo propõe-se a analisar o conceito de kairós vinculado à ideia de educação. Pretende-se focar ambas as noções no contexto de Os Trabalhos e os Dias, para ver em que medida os conceitos adquirem um papel central na obra.

Escolhemos o tema porque hoje, mais do que nunca, a educação representa um verdadeiro kairós enquanto oportunidade, momento propício, ocasião favorável e oportunidade da transformação possível.

Escolhemos algumas passagens de Os Trabalhos e os Dias em que Hesíodo interpela seu irmão. Cremos que nessas situações se pode ler uma espécie de microcena didática pela qual se definem papéis específicos. Hesíodo opera como um mestre e seu irmão ocupa o lugar de um discípulo a quem é necessário reconverter em relação a certas condutas que se mostram contrárias a um modelo ético. Neste contexto, a educação representa a oportunidade da transformação possível.

Regulatory and documentary standards of the sustainable development of urban agglomerations in the Russian Federation
Authors: Belozerov Vitaly , Shchitova Natalia , Sopnev Nikolai
Published: October 2021

The article considers the experience of classification documents of the territorial planning and management of urban agglomerations in the Russian Federation. We have analyzed the documents of the federal level the main aim of which is regulating the processes of formation and development of agglomerations in the country. The documents developed in the regions over the past ten years, which regulate the functioning of all Russian urban agglomerations including laws, concepts, strategies, territorial planning schemes, inter-municipal agreements, and regulations on the activities of coordination councils are considered in detail.

A comparative analysis of the documents allowed us to group agglomerations according to the degree of representation of the regulatory and documentary basis. There are five groups of agglomerations that differ in the number of documents and the degree of elaboration of agglomeration issues. The results revealed a significant gap between the selected groups. For agglomerations of the first and second groups we have prepared the complete sets of documentation, which reflect sufficiently the main parameters of agglomerations as integral system formations. For agglomerations included in the fourth group, there are no special documents, there are also some relevant materials in the regional documents of strategic and territorial planning which are characterized by poor elaboration. Agglomerations of the fifth group are not provided with regulatory documents at all, they are not considered as special formations.

The analysis can contribute to improving the methodology of agglomeration development, understanding the need to expand and improve approaches to the management of urban agglomerations as integral objects. It is obvious that the urgent problem of sustainable development and functioning of urban agglomerations is the need to develop an innovative management model, its coordination with the regulatory framework of regional management structures, and a clear definition of conceptual and terminological and spatial-structural parameters.

Authors: Abramov Sergey , Sluka Nikolay
Published: October 2021

The article discusses the experience of assessing the location of foreign TNCs in global cities as a significant factor in the field of environmental, economic and social aspects of sustainable development of urban areas. A number of initial theoretical models are proposed from the standpoint of the center-peripheral approach and a conceptual scheme of geoinformation and cartographic support of the study is presented, the main stages of its implementation are revealed. The databases of the European Commission’s Joint Research Center (GHS Urban Center Database, GHS-UCDB) and (GHS Functional Urban Areas, GHS-FUA) were used to get an idea of the real models of the intracity location of large business in the delimitation of the boundaries of agglomerations and their separate zones. To determine the composition of TNC divisions, Forbes 2000 data for 2020 and information from corporate websites on the branch network with geographic reference from the Craft.co reference service were used. In total, 55 global cities of the alpha group and more than 12 thousand foreign branches of TNCs were involved in the analysis. The processing and systematization of the obtained data was carried out using the object-relational database management system (RDBMS) PostgreSQL and the PostGIS extension. The visualization of the research results based on the consolidation of tabular data and spatial relationships using QGIS. Comparative analysis showed the effectiveness of the developed technique. As a result of its application, the overall scale of the presence of big business in the global cities of the alpha group and a significant gap between leaders and outsiders were determined. The absence of a universal model for the zonal distribution of TNCs in the urban space was revealed, the basic invariants of which were visualized using the example of a number of centers. The presented developments can contribute to the development of the direction of microgeographic research in geo-urban studies. In practice, the methodology can be useful for modernizing the assessment of the quality of the urban environment and the conditions for its formation as part of the implementation in the Russian Federation of the national project “Housing and Urban Environment”.

Published: October 2021

The article presents the results of a study of online information resources that form the modern media image of the Arctic.

Using a random sample, 25 online media were selected for analysis, of which five groups of information resources were identified. According to the keywords “Arctic”, “Northern Territories”, “Arctic Zone of Russia”, a database has been formed that includes 500 media texts. Based on their analysis, we tried to answer the questions about what is becoming the dominant media image of the Arctic formed by means of Arctic journalism at the present time, how balanced it is and how it meets the challenges of the time and state interests.

The territorial features of the distribution of media texts in the regions of the Arctic zone of Russia are revealed. In terms of their absolute number, the Murmansk Region and the Yamalo-Nenets Autonomous District are the leaders, and in terms of the number of publications per 10,000 people of the population—the Republic of Komi, or rather, the Vorkuta city district, the only one in this subject of the Russian Federation that is part of the Arctic zone of Russia.

The most and least frequently encountered topics of media texts are identified. Among the first are publications on the topic of the Arctic raw material potential (32 %), among the second—publications on social topics (6 %). Despite the diversity of media content and the availability of publications on such topics as housing and social security, quality of life, tourism, education, culture and traditions of the peoples of the North, the frequency of publications on social topics in the general flow is extremely low. It is concluded that the potential of this topic is currently not sufficiently disclosed in modern Arctic journalism.
Use of high-resolution images in local area management tasks
Authors: Erunova Marina , Gosteva Anna
Published: October 2021

For an enormous amount of time, people are trying to rationally use the territory where they live, work, and relax. There are a large number of methods to do this better and automate the process of effective territory management. One of the critical tasks of managing the territory is the operational monitoring of its current state. The best solution for this task is to use remote sensing data. According to MODIS data, currently, methods for active global monitoring of territories have been developed, and their archive began in 2000. However, this data has the insufficient spatial resolution to solve problems for local areas, such as an agricultural field, an urban neighborhood whose dimensions are comparable to the solution of 1-pixel MODIS. For such territories, it is necessary to use data with a higher spatial resolution.

The article describes the use of high-resolution satellite data from PlanetScope in the tasks of managing a local territory for four territories. 2 types of objects are considered: agricultural land is represented by experimental agricultural enterprise “Minino”, “Kuraginskoe” and “Mikhailovskoe”, urban land is represented by one object, the city of Krasnoyarsk. The statistical values of the NDVI, VARI, and CIGreen indices were obtained for each field in each farm during the entire growing season. The relationship between the annual course of vegetation indices and crops is analyzed. For the territory of the city of Krasnoyarsk, temperature maps were calculated according to Landsat 8 data with classification according to PlanetScope by the type of underlying surface, which allowed us to identify changes in the urban landscape by temperature anomalies.
The use of a software and hardware complex created on the basis of unmanned aerial vehiclesand GIS technologies for monitoring the erosion processes of the water protection zone of the Belgorod reservoir

Published: October 2021

Determining value of erosion network density in the water protection zone is the compulsory index in the automated information system of water bodies state monitoring.

The authors of the article developed and tested when studying the Tsimlyansk reservoir water protection zone recommendations for determining erosion network density by materials of distant inspections carried out using pilot-less aircraft (PLA) and tools of geographic information systems (GIS).

In the article assessment of erosion network density for the Belgorodsk reservoir water protection zone carried out using given recommendations is presented. Such inspections are especially actual for the banks where regular observation benchmark network is lacking or they have low transport accessibility.

Based on series of photographs made by pilotless aircrafts using Agisoft Photo Scan programme relief numerical models and orthophotomaps of the water protection zone are constructed. By direct and indirect signs position of tolwegs for the relief linear erosion forms of different orders—from furrows and grooves to brooks and small rivers. According to the recommendations developed by the authors, the water protection zone is divided into elementary segments and for every of them the value of erosion network density determined using GIS tools.

Assessment of erosion network density showed that on the background of general low degree of the relief horizontal dismemberment for the Belgorodsk reservoir water protection zone the reservoir right-bank within Shebekinsky municipal region was distinguished noticeably. The erosion network density of this plot by 5–7 times exceeds the value of this parameter for the whole water protection zone of the reservoir. And only here relief erosion forms fully located within the water protection zone predominate noticeably, that is not characteristic for the rest part e the reservoir cost.

Published: October 2021

The article presents the results of the work devoted to the analysis of the Sentinel-2/MSI optical images applicability for monitoring the snow cover pollution in industrial Arctic cities. Initially, the authors evaluate the accuracy of calculating the albedo values from satellite images based on the albedo ground-based measurements with a pyranometer in Moscow and Kirovsk. Statistical analysis has shown a high correlation between ground-based and satellite albedo measurements, which makes it possible to use quantitative albedo values in the spatiotemporal analysis of snow cover contamination. For three cities (Murmansk, Vorkuta, Norilsk) that differ in physical and geographical conditions and the type of industrial enterprises, the analysis of snow cover contamination for the period 2016–2020 was carried out. For Murmansk, the main pollutant is coal dust from the seaport, where coal is handled in an open way. In early 2020. the city authorities have completed the construction of a dust screen around the port terminals to reduce urban pollution. The analysis carried out in the work showed that the installed screen significantly reduced the area of pollution in the city of Murmansk. For terrain height more than 120 m, the albedo values correspond to the maximum values for the selected date, which indicates that coal dust spreads for territories located at altitudes of less than 100 m. It was not possible to identify long-term dynamics of albedo values for Vorkuta and Norilsk. Polluted snow cover is observed at a distance of up to 10 km from polluting enterprises.
Assessment of the size of very small glaciers in Khibiny mountains
Authors: Vikulina Marina , Zimin Mihail , Romanenko Fedor
Published: October 2021

The presence of very small glaciation in the Khibiny mountains was discovered by V.F. Perov in 1958. Since then and until the beginning of the 21st study of glaciers in this area has not been carried out. In general, warming is recorded on the Kola Peninsula. The average annual increase in temperature is 2.3°C ± 1°C during the last 50 years, which correlates with the data of other researchers. The glaciers in the Khibiny mountains should have significantly reduced their size in this connection. In other Arctic regions degradation of glaciation is noted. Some researchers predicted to disappear of Khibiny glaciation. In order to assess the change in glacier areas, we carried out a comprehensive study of small glaciers in the Khibiny mountains. We studied dynamics of glaciers over the past 15 years using field observations and the use of GIS and remote sensing methods. In our study, we used aerial photographs of 1958, digital models built on the basis of field measurements, and satellite images for years different in meteorological parameters. Our research shows, despite the slight degradation of glaciation, this tendency is modest and glaciers’ area remains relatively stable. Our research shows that glaciers shrank significantly in the early 2000s and showed a tendency towards complete disappearance. Their area has decreased by more than two times compared to the figures obtained in 1958. This fact may be caused by the increase in snow precipitation through in recent years. After 2007, there has been an increase in snow precipitation. In subsequent years, starting in 2008, the glaciers began to regain their size. Over the past 15 years, the average area of two glaciers (No. 3 and No. 4) exceeds the size of 1958. Glaciers No. 1 and No. 2 have shrinkage.
Remote sensing methods in the study of fractional vegetation cover of fallow lands
Authors: Poletaev Arseniy
Published: October 2021

The article discusses methods for studying fractional vegetation cover (FVC). The possibility of using satellite images from the Sentinel-2 satellite to study the fractional vegetation cover has been studied and the method for obtaining a raster of the fractional vegetation cover has been described. Fragments of classified rasters created by interpolation of points obtained from rasters of fractional vegetation cover to the study area for 2018–2020 are presented. The dynamics of the FVC indicator for 2018–2020 is shown, the variation of the maximum, average and minimum values for the specified period is determined. The comparison of the maximum, minimum and average values of the projective vegetation cover with the values of precipitation amounts according to the weather archive data for the periods between the used satellite images is carried out. A correlation analysis was carried out between the values of the FVC indicator (maximum, average, minimum) and the amount of precipitation, which showed a weak relationship between these values. The sums of the values of the average daily evaporation for the periods between the used satellite images were calculated, the values of the balance between the sums of precipitation and the sums of the values of the average daily evaporation were determined. The graphs of changes in the balance between the amounts of precipitation and the sums of the values of the average daily evaporation were compared with the graphs of changes in the FVC of the maximum, minimum and average. It was revealed that the maximum balance values precede in time the maximum FVC values, and the minimum balance values coincide in time with the minimum FVC values, or precede them. An example of the spatial relationship between the increased, in comparison with the surrounding background, the FVC values of the raster of the projective vegetation cover and mounds, highlighted by the elevation map obtained using the UAV, is shown.

Authors: Shvets Alexandra , Yakovenko Irina , Yakovlev Andrey
Published: October 2021

The article considers the methodology of cartographic study of geopolitical risks in the border region of the Black Sea region—Crimea. Geopolitical risks are presented as one of the options for potential constraints on the sustainable development of Crimea. Geopolitical risk refers to the situation of uncertainty that arises in the region in the process of changing its political subjectivity.

The program of a cartographic study of geopolitical risks in the region was proposed. It includes stages of exploration and mapping long-term dynamics of their manifestation in the region; identification of cause-and-effect relationships and mutual conditionality of factors of occurrence of geopolitical risks; forecast of socio-economic development and geopolitical risks in Crimea for the near and distant future; justification of the strategy of socio-cultural development of the Crimean region and preventive actions in the system of management of geopolitical situations. The results of the first stage of the study of geopolitical risks in Crimea are presented. A map of the dynamics of ethnic and confessional contradictions in Crimea in the period 1990–2015 is developed. An understanding of the contradiction as a stage of pre-conflict with the potential for peaceful resolution, but not overcome in content, is proposed. The localization of ethnic and confessional contradictions in the Crimea is analyzed. The regions and spatial foci of their concentration are determined. The emergence of ethnic and confessional contradictions in regions with increased ethnic mosaic is proved. A map of the geopolitical risks in Crimea that emerged after 2014 has been developed. The transformation of the types of geopolitical risks in Crimea is analyzed. It is noted that the possibility of the emergence of ethnopolitical contradictions and their addition to the risks of information manipulation of information about the region in the media, as well as the emergence of risks of terrorist activities on the territory of Crimea.

The conclusion is made about the spatial asymmetry of the localization of geopolitical risks in Crimea. A significant part of the geopolitical risks is localized in those regions of the peninsula that concentrate the economic and informational attractiveness.

The article discusses the creation of a new methodology for the development of geoinformation models of floods based on the use of operational reports of regional management bodies in emergency situations. The place of floods in the classification of emergencies is shown and the types of floods are given. The article describes the tasks of protecting the population and territories during the occurrence of floods, which are solved by regional emergency management bodies using various geoinformation models. Criteria for evaluating these models are formulated. Various methods of determining, predicting and constructing flood zone boundaries using a digital terrain model and remote sensing data are considered. The possibilities of using the data of operational groups of regional management bodies in emergencies, as well as additional sources of information, are investigated. The order of actions of operational groups in the emergency zone is investigated and the algorithm of response by regional management bodies in emergency situations to the occurrence of floods is compiled, the need for cartographic support is determined. On the basis of the information received from the reports of the operational groups, the objects in the emergency zone are analyzed, the data on which is necessary for the further development of the cartographic support of the regional management bodies in the emergency. A new classification of the characteristics of objects subject to rescue and evacuation from the flood zone is proposed. Based on the obtained classification, a database scheme for the new geoinformation model is developed. To standardize the data received by operational groups in the emergency zone, formalized report forms have been developed. The main layers of the digital cartographic basis of the new geoinformation model and the order of their creation are described. A scale for visual assessment of the level of flooding of buildings and land plots and symbols for displaying the obtained indicators on the map has been developed. New types of cartographic support for regional emergency management bodies for organizing operational actions in the flood zone are proposed. A new method for calculating the individual risk of flooding for each object in the flood zone is described. The scheme of the new geoinformation model of flooding is given.

Authors: Adakhovskiy D.A.
Published: October 2021

The article analyzes the zonal landscape distribution and the structure of the diurnal lepidoptera ranges on the territory of the Udmurt Republic. The zonal indicators of the dynamics of the species richness of lepidoptera in the region have the following form: the southern taiga - 100 species, the subtaiga as a whole-122 species, including the northern band of the subtaiga-107 species, the southern band of the subtaiga-119 species. The zonal trend is based on the significant participation of the regional fauna of the regional representatives. The general indicators of the numerical participation of structural and arealographic groups in the fauna are as follows: 46 species are located within the generalized part of the area in the region; 22 species are located near the periphery of the area; 42 species are located on the border of the area; 13 species are located on the periphery of the area. The main share of lepidoptera located in the marginal parts of their ranges is made up of southern subboreal (steppe and non-morale) and subboreal-subtropical representatives (72 species). The proportion of such species among the northern geographical groups - the Hypo-Arctic and boreal (16 species) is significantly lower. The most important biochorological units that determine the conditions for the distribution and localization of bulavous are uplands, forest landscapes on the sands, as well as the valleys of large and medium-sized rivers in the southern part of the region.
THE NEEDS OF THE POPULATION OF KIROV REGION AS THE FACTOR OF THE TOURIST AND RECREATIONAL SPACE CREATION
Authors: Konyshev E.V.
Published: October 2021

The tourist and recreational needs of the population are major factors in the tourist and recreational space creation. The identification of needs should be systematic and involve all components of tourism and recreation. The relevance of this paper due to the need to provide scientific support to the processes of spatial planning and management of tourism and recreation in the Kirov region. The regulators currently overlook the recreation focusing only on tourism. The aim of this examination is study of the needs of Kirov region population and research on the specificities of the organization of recreational activities of the population in enterprises, in free time after work, on weekends and during long vacation. The survey has been used in order to achieve the objective. The survey was conducted among 2125 persons in online form. Several types of questions have been selected to identify features of inclusive and daily recreation, recreational activities on weekends and during long vacation. In addition, the attitude of residents to the advantages and disadvantages of rest within the Kirov region, the sums of money allocated for leisure and travel, and the attitude to services of travel firms were determined. The results have been found out the low level of satisfaction with leisure activities in the workplace, a lack of recreational areas and occasional breaks, which have a negative impact on overall productivity. The organization of recreational activities on weekends and vacation is less problematic for residents, but is often implemented in the cheapest and passive forms and on an independent basis. The research results can be used to improve the processes of territorial planning and management of the regional tourist and recreational system of the Kirov region.

INTISARIBanjir adalah bencana alam yang sulit di deteksi kapan akan datang terutama di musim hujan. Meskipun sudah dilakukan upaya dengan melakukan analisis terhadap data curah hujan serta tinggi permukaan air setiap periodenya, namun upaya tersebut dirasa masih belum dapat menyelesaikan permasalahan yang ada. Selain dari sisi manusia nya sendiri, solusi dari sisi teknologi juga diharapkan dapat penyelesaian permasalahan ini. Teknologi untuk deteksi dini bencana banjir akan dibutuhkan sebagai alternatif untuk membantu menyelesaikan permasalahan serta membantu dalam proses pengambilan keputusan guna meningkatkan kinerja instansi yang bekerja untuk memantau volume air sungai sehingga memperoleh kondisi air yang lebih cepat dan akurat. Tinggi permukaan air tentu menjadi salah satu faktor yang menyebabkan potensi banjir dimana permukaan air dapat diukur. DTMF merupakan metode pensinyalan yang nantinya akan dipadukan dengan sensor yang dapat digunakan untuk mengukur ketinggian permukaan air yang hasilnya nanti akan dikirim melalui gelombang radio. Dengan pengiriman sinyal melalui gelombang radio ini maka akan lebih efektif karena tidak memerlukan biaya seperti halnya melalui sms dan IoT.Kata kunci— DTMF, Arduino, Pendeteksi Banjir, SWOT, Gelombang Radio ABSTRACTFloods are natural disasters that are difficult in the detection of when it will come mainly in the rainy season. Despite efforts by conducting an analysis of the data of rainfall and high water levels at each, but those efforts proved still unable to resolve the existing problems. Aside from the human side of his own, the solution from the tech side is also expected to be the resolution of this issue. Technology for early detection of catastrophic flooding will be required as an alternative to help solve problems as well as help in the decision-making process in order to improve the performance of agencies who work to monitor the volume of river water so obtain water conditions more quickly and accurately. High water levels would certainly be one of the factors that lead to potential flooding where water levels can be measured. DTMF signalling is a method which will be combined with sensors that can be used to measure the height of the surface of the water which results will be sent via radio waves. With the delivery of the signal via radio waves it then it will be more effective because it doesn't cost as much as through sms and IoT.Keyword — DTMF, Arduino, Flood Detection, SWOT, Radio Wave
