The Effect of Dust on Solar PV System Energy Output Under Urban Climate of Surabaya, Indonesia
Authors: Tarigan Elieser
Published: November 2019

Solar Photovoltaic (PV) electricity is one of the most effective, eco-friendly, and sustainable source of energy. The amount of electricity produced by a PV system is directly affected by the level of solar irradiation incident to the PV panels. In the real operation, the dust from the surrounding environment falls and accumulates on PV panels. The accumulation of dust causes a decrease in the energy output of the PV system. This study was aimed to investigate the impact of dust on PV operation to its energy output under the urban climate of Surabaya, Indonesia. The study was conducted by comparing two identical PV panel systems, each of 300 Wp. For one system, the PV panels were manually cleaned regularly for the dust, while for another system is remained without any cleaning. Both systems were measured for their energy output, and the results are compared. The results showed that, during the dry season in Surabaya, the energy output from the cleaned PV panels system is higher by 20% in comparison with the uncleaned PV panels system. While, during the rainy season, both systems produce the same amount of energy. In total throughout the year, cleaning of PV panels system would increase the energy output of about 8%.

Recently, the internet of thing (IOT) has been growing rapidly in many fields including in the biomedical vital sign monitoring of a human. Heart rate and SPO2 are vital sign parameters for human life. Those parameters needed to be observed for patients in an emergency situation. In patient care at hospitals, doctors need to monitor the patients’ heart rate and SPO2 parameters continuously. Therefore, the objective of this study was to develop the heart rate and SPO2 parameters based on IOT technology. The heart rate and SPO2 parameters were detected using a finger sensor and an oximeter sensor, respectively. The digital data from those sensors, further, was processed using ESP8266 microcontroller. By using a built-in Wi-Fi module in ESP8266, the vital sign was sent to the user wirelessly to handphone or central monitor using Think Speak application, remotely. In this experiment, the sensors were placed on the finger while the patient was in the standing, lying or sitting position. In the same position, the parameters were acquired for ten times. Some analyses were conducted to find the accuracy of the measurement. The results showed that the uncertainty were 0.26 and 0.04 for heart rate and SPO2, respectively. Based on the medical standard calibration (<3%), those parameters are feasible to be used in the medical system measurement. The T-test analysis statistics for one independent sample was performed to obtain a significant difference among the data. The p-values were 0.118 and 0.000 for heart rate and SpO2, respectively. Finally, this study suggested that the IOT system was able to monitor the parameters effectively.

Published: November 2019

Proportional-Integral-Derivative (PID) control is one of the famous controllers applied in industrial and robotics world. It is quite easy to understand and to be implemented. It is known that, with a proper combination of its gain parameters, a system with good performance can be obtained. This parameter tuning can be tricky since the number of the combination is almost infinite. Hence, methods to tune the parameter gains of proportional, integral and derivative is needed. Some optimization methods that can be used in tuning parameters are Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Differential Evolution (DE). The paper will analyse the performance of those methods by applying them in PID Controller to control a Direct Current (DC) motor system by comparing the iteration time, the number of parameters, and augmented system performance. The comparison is done on MATLAB simulation by using the same computer. It results as DE as the best among them with the least number of parameters and best DC motor system performances.

Published: November 2019

Anemia is a global nutritional problem in developing countries. Oral iron supplementation is recommended for anemia treatment in pregnant woman, and adolescent girl. However, this supplementation frequently has some side effects. In a previous study, snake fruit seeds naturally contain high level of iron, which is potentially used for alternative anemia supplementation. This study aimed to investigate the effect of snake fruit seed extract (SSE) on body weight (BW) in female rat model with anemia. The study was a pre-posttests control group design, 14 female rats strain Wistar were selected based on inclusion criteria. After 10 days modelling of anemia, all rats were randomly divided to 2 groups: control and treatment groups. For the remaining days, all rats received low iron feed, but added 1.75 g/kg BW/day SSE in the T group 14 days treatment. Body weight was measured before and after treatment, and all data were analyzed using independent and paired T-tests with p<0.05. Before treatment, the average of BW in the C group is lower than T group (p=0.005). After treatment, the average of BW in T and C groups were statistically differed from BW before treatment (p<0.001). In addition, a greater number of BW was found in the T group, compared with the C group (p<0.001). The administration of 0.175 g/100 g BW/day SSE can increase BW in female rats model with anemia.

Imbalance in liver metabolism lead to oxidative stress mainly caused by free radicals or termed as reactive oxidative oxygen (ROS). Prolonged ROS exposure without proper treatment induce severe liver damage and serious hepatic diseases including cirrhosis. Eugenol (4-allyl 2-methoxyphenol) is phenolic derivative compound that showed antioxidant, anti-inflammatory, analgesic, antibacterial, antifungal, and antitumor activities. This study aims to evaluate the hepatoprotective effect of eugenol through biochemical markers analysis. Cytotoxic assay was performed in various concentrations of eugenol (3,125; 6,25; 12,5; 25; 50; 100 μg/mL) using (3-(4,5-dimethylthiazol-2yl)-5-(3-carboxymethoxyphenkyl)-2-(4-sulfophenyl)-2H-tetrazolium) to determine the safe concentrations for next assays. Aspartate aminotransferase (AST), alanin aminotransferase (ALT), and lactate dehydrogenase (LDH) assay were performed using colorimetric method to evaluate the levels and activity of liver-related enzymes which are elevated in damaged liver as they were used as hepatotoxicity markers. The viability of HepG2 cells increased in eugenol concentration 3.125 μg/mL and then decreased along with the rise of eugenol concentrations. From this cytotoxic assay, two concentrations of eugenol were choosen (6.25 and 25 ug/ml) to be evaluated in the next assays. The level of LDH, ALT, and AST decreased after eugenol treatment compared to negative control. The most effective concentration of eugenol to seemed different in certain hepatotoxicity markers. This study suggests that eugenol was safe to use for cells culture environment in large ranges of concentrations and shows hepatoprotective effect in APAP-induced hepatotoxicity model by the decrease of LDH level and AST and ALT activities.

Physiologically, the influence of inundated conditions on many plants varies. The eco-physiological response of most plantations to flooding is wilt and stomata closure, root damage, reduction of root biomass2. This results in a decrease in the production of bioactive compounds, which have an effect on decreasing antioxidant activity. Various methods of measuring antioxidant activity still use chemicals through extraction processes that require a long time. So, it is necessary to examine alternative methods that are cheap, easy and fast. This method is digital processing. The leaf samples were then photographed for image analysis in the Telkom School Banjarbaru Multimedia Laboratory. Antioxidant activity was analyzed through the hydroxyl scavenging method at the laboratory of Biochemistry and Biomolecular, Faculty of Medicine, Lambung Mangkurat University, Banjarbaru. The results of image analysis showed that the antioxidant activity model of RGB values was AA= -54.9592 +1.0295 R + 0.3757 G + 2,006 B -0,0004 R*G - 0.0012 R*B + 0.004 G*B (AA = antioxidant activity; R = red; G = green; B = blue) with p = 0.001 (p <0.005) and r = 0.76. In this model, the R value has a significant effect on antioxidant activity. Image analysis using RGB can be used to measure leaf antioxidant activity. However, further research is needed.

Published: November 2019

Changes in groundwater levels in the indutrial area were seen on ground air maps from the Directorate of Environmental Geology in 2003 and 2010. Digitization of groundwater level maps was carried out and then the changes were analyzed for getting the volume of water used. Time-lapse microgravity is sensitive to density changes. To get the value of density changes of groundwater, we need information such as rock porosity and water density. In this case we assumed that the porosity value is 30% and the water density value is 1 gr / cc, so the value of water density changes is 0.3 gr/cc. The value of density changes is distributed across the entire volume of groundwater changes during 2003 to 2010. The volume of groundwater changes in interval 2003 to 2010 was around 33,971,200 m3. From calculation of time-lapse microgravity for geometry the reduction of groundwater in the Dayeuhkolot industrial area shows the highest value about -125 microGal. The time-lapse microgravity of the Dayeuhkolot industrial area during 2003 to 2010 shows a value -125 microGal which is very detectable with a gravimeter like Scintrex CG-5 which has accuracy up to 1 microGal.

Graph theoretical analysis plays a vital role in various fields. In Graph theory, Graph labeling is the major area of application. Graph labeling is the assignment of labels to the vertices and edges of a graph pertaining to certain conditions. Graph theory finds its applications in Coding theory, Radar, Astronomy, Circuit designs, Communication networks, X-ray crystallography, Data base management and a major role in medical field like Brain network, Forensics and Cephalometric analysis. Here we would like to enhance the graph theory applications in the field of Psychology. This paper gives an overview of graph techniques applied in Sociometry using Sociogram. Sociometry is a quantitative method for measuring social relationships and Sociogram is a tool to find Sociometry of a social space. In this article, an analysis in a classroom climate with of a group of 50 college students was done after they were subjected to answer a series of questions probing for affiliations with other classmates. A graphical representation (sociogram) of the social links of each student was constructed by plotting the structure of interpersonal relations in the group. This graphical representation depicts the social relations, channels of influence, attraction towards others, hatred, isolation and lines of communication of the group.
Application of Fractals to Detect Breast Cancer
Authors: Datta Debabrata , Sathish Shakeela
Published: November 2019

Breast cancer is one of the major causes of death among women. Small clusters of micro calcifications appearing as collection of white spots on mammograms show an early warning of breast cancer. Image segmentation is an important element of Digital Image processing that subdivides the image into discrete regions/objects, each identified by the property of homogeneity of pixels. X-ray mammography is used as diagnostic tool for diagnosis of breast cancer. Edge detection of micro calcification clusters in mammogram images is the main issue of early detection of breast cancer. Fractals are of rough or fragmented geometric shape that can be subdivided in parts, each of which is a reduced similar of the whole. Fractal dimension and Hurst exponent are used to locate the micro calcifications in the mammogram. The concept of fractal is associated with geometrical objects satisfying criteria such as self-similarity and fractal dimensionality. Present method of edge detection is superior compared to conventional Sobel method, in which detection of edges of the regions or objects in an image takes place by the Fudge factor. The paper presents the application of fractals for early detection of breast cancer.

Solution of Multi Objective Transportation Problem Under Fuzzy Environment
Authors: Gowthami R , Prabakaran K
Published: November 2019

The crisp transportation problem is one of the special case of linear programming problems. It is explained with the hypothesis that the cost parameters are indicated inaccurate way. But in the present world, the transportation parameters may be uncertain due to many uncontrolled factors; this gives rise to fuzzy environment. Here, we proposed a method for the solution of fully fuzzy multi objective transportation problems involving triangular fuzzy numbers. We solve the fully fuzzy multi objective transportation problems without converting it into crisp form. A numerical example is discussed to demonstrate the theory formulated in this article.
Effective heat action plans: research to interventions
Authors: Ebi Kristie L
Published: November 2019

Strengthening the links between research and interventions would mean new insights could be translated more quickly into actions to protect and promote population health. Doing so requires strong collaboration among funders, the research community, and stakeholders, to understand stakeholder needs, constraints, and opportunities, and to focus research questions so results are useful, useable, and used. Continuing increases in the frequency, intensity, and duration of heatwaves underscores the urgency of fostering two-way communications between researchers and those responsible for designing and implementing heat action plans, to ensure research is effectively targeted to further reduce heat-related morbidity and mortality in a changing climate.
Changes of tropical cyclone activity in a warming world are sensitive to sea surface temperature environment

While there is considerable agreement in the scientific community about the intensification of tropical cyclones (TCs) in a warming world, that consensus does not exist for TC frequency. In order to shed new light on this uncertainty, we classified the global oceans into three pools based on SST percentiles: the (a) warm (≥90th percentiles), (a) moderate (65th–90th percentiles) and (c) cool (<65th percentiles) pools, and found that TC frequency increases significantly over the cool SST pool but decreases in the warm and moderate SST pools. The differences in TC frequency change is large among the three pools, contrasting to the small trend differences of TC intensity.
Features of reforestation in the longterm agricultural use of geosystems of the Tunkinskaya depression
Authors: Atutova Zh V
Published: November 2019

The paper focuses on identifying the features of natural reforestation after abandonment of agricultural land. That was achieved by the annual monitoring (2014 to 2018) of current state of 22 fallow land sites within the most agrarian-developed areas of the Tunkinskaya depression (Republic of Buryatia). Geobotanical analysis of the species composition of woody and grass covers of fallow lands was carried out. The main options for overgrowing fallow lands were determined. This is a restoration through birch, pine or mixed undergrowth, as well as meadow succession. Natural reforestation on fallow lands flows more intensively around the perimeter of the fields. The species composition of the undergrowth is identical to the forest canopy of the adjacent forests. In the grass cover of fallow lands in most cases there is a dominance of meadow species. In the grass cover of the surrounding forests, forest species prevail. Our research confirmed the dependence of distribution intensity of tree undergrowth on the degree of remoteness from the forests surrounding the abandoned lands. A decrease in the excess growth of tree species was observed with increasing distance from the periphery of the field to its centre.
Natural resource zoning: theoretical and methodological approaches
Authors: Ya Baklanov P
Published: November 2019

We propose to delineate the territorial combinations of natural resources as a basis for natural resource zoning. The territorial combinations of natural resources are distinguished by the presence of the inter-resource ties of two types: the direct and indirect links of resource-containing components in natural geosystems, and the indirect links of resource-containing components through the components of territorial socio-economic systems that are formed in the process of mastering natural resources. We offer the following algorithm of a natural resource zoning: delineation of a relatively holistic natural geosystem: definition of its allocated resource-containing components, including the deposits of mineral resources, areas of land and forest resources; determination of geosystem inter-resource links, primarily, the links of separate natural resources with the largest ones; setting, as a result, the territorial combinations of natural resources existing in this natural geosystem; exploration of the inter-resource ties, which either exist or can be established in the process of extracting and using certain natural resources through the components of territorial socio-economic systems, including the links of transport systems and certain settlements. These inter-resource ties are superimposed on the geosystem links, and more complete territorial combinations of natural resources are allotted as a basis of natural resource areas.

Published: November 2019

Compliance with environmental priorities in the economic activities of the regions should be an important direction in solving socio-economic problems in order to transition to “green” economic growth and sustainable development. For the regions of the Baikal natural territory (BNT) the paramount importance is to assess the intensity of the main types of environmental pollution in order to determine the ratio of the results of economic activity to the level of its negative impact on the environment. The paper presents a comparative analysis of indicators of environmental capacity, such as eco-intensity and per capita emissions on the example of the regions that are part of the BNT, which include the Republic of Buryatia, Irkutsk region and Zabaykalsky Krai. Also, it was necessary to determine whether there is a mismatch in economic activity between the rate of economic growth and the consumption of resources and the environmental impact on the environment, that is, the achievement of a decoupling effect. The obtained results of modeling to assess the current economic situation on the example of the Republic of Buryatia, taking into account environmental parameters, allowed identifying the main factors that have the greatest impact on per capita emissions. A positive aspect of the economic activity of the Republic of Buryatia is the observed decrease in per capita emissions, with an increase in the growth rate of the main economic indicators, which indicates the presence of the decoupling effect.

Published: November 2019

The article is devoted to the problem to solve the contradiction between economic development and environmental protection in the Baikal Natural Territory (BNT). We reveal the problems of unbalanced economic and environmental development of the Republic of Buryatia. We have conducted the economic losses analysis of the republic caused by the impact of environmental restrictions. We have carried out a territorial analysis of the economic development of Buryatia. We substantiate the necessity of distinguishing two types of economic policy in certain territories of the Republic of Buryatia, depending on the nature management regime: for the northeast of the republic and another part of Buryatia, which is part of BNT. We indicate the necessity of developing special mechanisms for the strategic management of the socio-economic development of Buryatia, including targeted support of the Government of the Russian Federation. Moreover, we have developed proposals for public authorities on a balanced solution of socioeconomic and environmental problems in BNT. We show the necessity of developing separate documents for strategic planning of the development of the Republic of Buryatia, taking into account the “Baikal factor” and the preparation of conditions for the new types of products produced in the republic intended for environmental protection.
