Published: June 2021

Soil is an essential structural material since it must be able to support the load applied, which is why soil must have sufficient bearing ability. The dry density affects the strength and deformation parameters. To achieve stable soil and meet the technological specifications for building a foundation, good embankment condition necessitates compaction. In this analysis, the updated proctor method was compared to the soil compaction energy proctor test method. Compaction energy is a crucial factor in assessing the soil’s intensity, and it must be taken into account during the planning stage. The laboratory’s Standard Proctor density was 1.63 gr/cm3, and the modified proctor density was 2.18 gr/cm3, according to the findings of this report. The outcome of the soil density sand cone test indicates that the degree of soil density is 97.31 percent for the standard proctor test process, indicating that the soil density has been achieved and the soil embankment should be used, but as applied to the soil density in the laboratory by standard proctor test, the degree of soil density is 73.54 percent lower.

Technology in the construction industry is now rapidly developing. Construction technology, which synergies with good construction management, can increase cost efficiency, time, and project quality. In conventional construction methods, there is a high level of uncertainty. The high level of uncertainty impacts poor project control resulting in project delays, high overhead costs, and a decrease in project quality. Modular home fabrication technology was developed to reduce project costs and time and improve project quality. The increasing demand for proper housing is currently encouraging Indonesia’s Government to create a Subsidized Housing Program. ‘Y’ subsidized housing is one of the subsidized housing in Indonesia. The ‘Y’ subsidized housing construction still uses conventional construction. How to compare the achievement of efficiency in cost and time plans as well as project quality between the application of modular home fabrication technology with traditional construction in ‘Y’ subsidized housing construction, with potential project cost savings of 5-15%, acceleration of project duration of 9 months from planning, and inspection the quality of the project is done in stages? The achievement of cost and time efficiency of the project and improving the quality of the project affect the choice of the construction method. Modular home fabrication technology can be implemented if the modular manufacturer meets the criteria. These criteria are: including being qualified in modernization, having a consistent level of productivity, having adequate mobilization, and commitment that is always maintained to see prospects.

Published: June 2021

The source of backup power supply at telecommunication BTS is only temporary because its power only depends on the generator and battery capacity used. However, on the other hand, the backup power system is rarely monitored due to a lack of resources such as human resources and the remote location of the equipment/site. Meanwhile, the use of Android which is open source is now widely used by the public for many things, but there are still not many Android applications used to control the power supply system. The purpose of this research is to design and analyze the automatic backup power system on the integrated power system in the telecommunication network by adding an Android application to monitor the occurrence of faults in the system. The communication used in this research is the connection of the automatic backup power control circuit, the microcontroller, the webserver, and the android application itself. Automatic backup power control circuit in the form of a main power transfer control circuit, for example, the power from State Electricity Company (PLN), if a problem occurs it will switch to the back-up power in the form of a generator and battery. The results show that the design of the automatic power system device can work properly.

Authors: Naifah  , Hasan Muttaqin , Saidi Taufiq
Published: June 2021

High strength concrete (HSC) requires high amount of cement in order to make it more dense and compact. Using diatomaceous earth (DE) is an alternative to reduce the cement content in HSC. In this study the DE was used as cement replacement at the 0%, 5%, 10% and 15% replacement levels. The water to binder ratio was 0.3. The type F superplasticizer at 1.5% of cement weight was added. The DE was first ground, sieved with sieve #200 and calcined at 600°C for 5 hours before it used as cementitious material. The 50 mm cube specimens were prepared, cured in the water for 28 days, and then immersed in 10% NaCl solusion. After 1 and 2 months of immersion period, the surface visual appearance, mass and compressive strength of the specimens were examined and compared with the unimmersed specimens. The surface visual appearance shows that the HSC with 15% has smallest damaged as well as smallest degradation of compressive strength. However, the smallest mass loss was obtained at the HSC with 5% DE content.

In our present research was focused on production of biogas and biofertilizers from biogas plants in separate studies. Our research forms a basis for production of biogas from low cost material available in environment. Important factors determining good quality biogas are: waste quality, digester design, temperature, system operation, presence of oxygen. In our present study, we have considered two factors as different wastes and design of biogas plants. Further, different kinds of wastes including plant wastes were used. Two designs of digester were used in the present study Raw materials used in our present study are chicken manure, chicken manure while from plants used straw (Oryza sativa), cabbage (Brassica oleracea) waste and water hyacinth (Eichhornia crassipes). Materials for biogas plant were gallon water cylinder, plastic bag, plastic hose, water faucet, motorcycle tyre and glue. The biogas plant differed in being an anaerobic fermentation unit. One biogas plant using motor tires as a gas container of anaerobic fermentation process while others use plastic bags. Refinement of the other part is carried out during the study such as inlet and outlet holes where there were 4 points and to be 2 hole points. Reducing the hole on biogas plant can reduce the leakage of the resulting gas. The parameters measured are the length of the gas produced by the flame test, gas volume in 15 days and the fire color. The total volume of mixture is 12 liters, its contain of 6 liters’ water and 6 liters the mixture manure and plant. Ratio of mixture between animal manure and plant are 6:0; 4:2; 3:3; 2:4; 0:6. The result show that the using of biogas plant with plastic bag is better than the using of motorcycle tires. From statistical analysis generally showed that the best mixture of yield was 3: 3 mixture based on gas production parameters and flame color. Comparatively, mixture chicken manure and goat manure had the best result for gas production.

Published: June 2021

Information and Communication Technologies (ICT tools) are the important teaching resource in modern school. Each new didactic tool is introduced into educational process in order to increase the effectiveness of this process. The paper concerns the research on the efficiency of using ICT in mathematics education. The research on effectiveness of using ICT in average secondary school in Bialystok conducted at the University of Bialystok with using research in action method is described in this paper. It was a preliminary study of what was happening at school in the classroom in the everyday didactic work with using ICT in proper didactic situations and in everyday school circumstances. Progress in using computer for change of style of work during math lesson (from drawing graphs in exercise book to concluding and structuring knowledge) was visible and quite fast. Some students noticed better results of their class tests after lessons with computer. Maybe it is a result of better understanding topics or possibility of solving more exercises instead of drawing graphs by hand. That indicates in some way the change in effectiveness of learning in new circumstances. Connection between using computers in math education and the individual development of the student and his progress in learning mathematics under the influence of using ICT in individual research work and the independent construction of mathematical knowledge will be investigated in the next stages of research.

Programming sequential motion steps in 4D-printed hygromorphs by architected mesostructure and differential hygro-responsiveness
Authors: Tahouni Yasaman , Krüger Friederike , Poppinga Simon , Wood Dylan , Pfaff Matthias , Rühe Jürgen , Speck Thomas , Menges Achim
Published: June 2021

Through their anisotropic cellular mesostructure and differential swelling and shrinking properties, hygroscopic plant structures move in response to changes in the environment without consuming metabolic energy. When the movement is choreographed in sequential time steps, either in individual structures or with a coordinated interplay of various structural elements, complex functionalities such as dispersal and protection of seeds are achieved. Inspired by the multi-phase motion in plant structures, this paper presents a method to physically program the timescale and the sequences of shape-change in 4D-printed hygromorphic structures. Using the FDM 3D-printing method, we have developed multi-layered, multi-material functional bilayers that combine highly hygroscopic active layers (printed with hygroscopic bio-composite materials) with hydrophobic restrictive and blocking layers (printed with PLA and TPC materials). The timescale of motion is programmed through the design of the mesostructured layers and 3D-printing process parameters, including thickness (number of printed active layers), porosity (filling ratio of the active layer), and water permeability (filling ratio of the blocking layer). Through a series of experiments, it is shown that the timescale of motion can be extended by increasing the thickness of the active layer, decreasing the porosity of the active layer, or increasing the filling ratio of the hydrophobic restrictive and blocking layers. Similarly, a lower thickness of the active layer and lower filling ratio of all layers result in a faster motion. As a proof of concept, we demonstrate several prototypes that exhibit sequential motion, including an aperture with overlapping elements where each completes its movement sequentially to avoid collision, and a self-locking mechanism where defined areas of the structure are choreographed to achieve a multi-step self-shaping and locking function. The presented method extends the programmability and the functional capabilities of hygromorphic 4D-printing, allowing for novel applications across fields such as robotics, smart actuators, and adaptive architecture.
The M-LED platform: advancing electricity demand assessment for communities living in energy poverty
Authors: Falchetta Giacomo , Stevanato Nicolò , Moner-Girona Magda , Mazzoni Davide , Colombo Emanuela , Hafner Manfred
Published: June 2021

Globally about 800 million people live without electricity at home, over two thirds of which are in sub-Saharan Africa. Planning electricity access infrastructure and allocating resources efficiently requires a careful assessment of the diverse energy needs across space, time, and sectors. Because of data scarcity, most country or regional-scale electrification planning studies have however assumed a spatio-temporally homogeneous (top-down) potential electricity demand. Poorly representing the heterogeneity in the potential electricity demand across space, time, and energy sectors can lead to inappropriate energy planning, inaccurate energy system sizing, and misleading cost assessments. Here we introduce M-LED, a Multi-sectoral Latent Electricity Demand geospatial data processing platform to estimate electricity demand in communities that live in energy poverty. The platform shows how big data and bottom-up energy modelling can be leveraged together to represent the potential electricity demand with high spatio-temporal and sectoral granularity. We apply the methodology to Kenya as a country-study and devote specific attention to the implications for water-energy-agriculture-development interlinkages. A more detailed representation of the demand-side in large-scale electrification planning tools bears a potential for improving energy planning and policy.

Authors: Kadhim Hadaf Mahdi , Munn C. B. , Gilpin M. L.
Published: June 2021

The halophilic bacterium Vibrio parahaemolyticus is widely distributed as a natural inhabitant of marine and estuarine environments throughout the world. Many strains are avirulent in humans, but virulent strains are the causative agent of gastroenteritis acquired through consumption of contaminated raw or undercooked seafood. Therefore, it is likely that most V. parahaemolyticus isolates from the marine environment are harmless to humans. Virulent isolates are difficult to differentiate from the majority of avirulent environmental isolates. A total of 55 V. parahaemolyticus isolates (22 clinical, 31 environmental and 2 reference strains) were examined for the carriage of plasmids, whole cell protein profiles; their haemolytic, lipase, phospholipase, protease and urease activities; and the cytotoxicity of their extracellular products (ECPs). Analysis of variance for V. parahaemolyticus isolates showed that Kanagawa haemolysis, phospholipase, protease and urease activities were significantly related to cytotoxicity as assayed by measuring relative extracellular lactate dehydrogenase as an indicator of damage of CHO-K1 cells. The difference between the mean values of cytotoxicity of ECPs of clinical and environmental isolates was significant at a p value of < 0.05.

The design of the experiment was randomized complete blocks (RCBD) in a factorial arrangement consisting of two factors with three replicates (3 plant species × 11 fungicides concentrations × 3 replicates); the first factor of three species of Brassicaceae plants: Arugula (Eruca sativa Mill.), Radish (Raphanus
sativus L.) and Garden cress (Lepidium
sativum L.), while the second factor included eleven concentrations of fungicides (Bayfidan, Tapsen 50 and Sigal). The mean of the treatments was compared with a significant difference in the use of less significant difference (LSD) when referred to significant effect at P ≤ 0.05 probability level, the results showed the superiority of radish plant on arugula and garden cress by statistically significant in enzymatic activity of α-amylase and protease. While the increase of enzymatic activity of polyphenol oxidase and concentration of MDA for arugula plant compared to radish or garden cress, and the latter had the most catalase activity and significant in terms of arugula and radish. The significant effect of triple mixture of fungicide treatment (Bayfidan + Tapsen 50 + Sigal) in increasing the enzymatic activity of the majority of enzymes and MDA, except for the enzymatic effect of catalase which was reduced by the treatment of different fungicides concentrations. Significant interference between plants and fungicides returned with positive statistical results by recording the treatment with the triple mixture of fungicides (Bayfidan + Tapsen 50 + Sigal) achieved the highest enzymatic activity of polyphenol oxidase and protease, as well as MDA concentration in arugula plant.

The study period started from summer 2019 to winter 2020 included measuring the concentration of three heavy elements, (lead, cadmium and copper) for two types of aquatic plants (Phragmites australis and Syllibium marianum), for two seasons summer and winter. The results of measurement of the concentration of heavy elements are shown, the highest average concentration of elemental Lead was 63.51 ppm in the reed plant Phragmites australis during the winter season. For Cadmium concentrations, the highest concentration in plants was 0.434 ppm in thistle Syllibium marianum samples during the winter season. The concentration of the copper element in the plant samples reached the highest significant concentration of 20.84 ppm in the reed plant Phragmites australis during the summer. The element concentrations in the models were estimated with the English made Flame Atomic Absorption Spectrometry Buck 210 VGP. The result and levels obtained from the study were higher than the cheeks allowed by the world health organization (WHO) for drinking water.

Objective : Gram-negative bacteria with Extended-Spectrum β-Lactamase (ESBL) genes are of concern due to their susceptibility to multi-drug resistance. The goal of this research is to investigate the gene coding of resistance of ESBLs encoded by the VEB gene and GES gene to modern β-lactams. Method : seventy wound swabs were taken from diabetic foot ulcer patients in period from October (2019) to February (2020). The collected samples were cultured on different media agar to identify by morphological, biochemical tests and Vitek 2 system. To determine VEB gene and GES gene using the methodology of Polymerase chain reaction (PCR) on the isolated bacteria. Result : a total of 50 Gram negative bacteria. The distribution of VEB gene was Proteus ssp. 7, Morganella morganii.ssp. 2, Klebsiella oxytoca 1, Acinetobacter baumannii 2. While the GES gene distribution was Escherichia coli 1, Proteus
ssp 1, Morganella morganii. ssp 4, Acinetobacter baumannii 1. Conclusion : The VEB gene and GES gene plays an important role in the resistance to new β-lactams of ESBL-producing isolates.

Antimicrobial resistance (AMR) is one of the greatest public health challenges of our time, primarily due to inappropriate antimicrobial use. Addressing this threat is a public health priority that requires a collaborative global approach in all areas. The rational use of antimicrobials is the main strategy for the prevention of antimicrobial resistance, which can be achieved by changing the behavior and knowledge of the prescribers. So, for the success of any problem management program, the most important prerequisite is community participation. Therefore, this study aimed to assess the knowledge and attitude of the samples of community members, pharmacists and health professionals in the city of Al-Suwaria, in the province of Wasit, in the Middle East of Iraq, with respect to antimicrobial resistance, which helps to rationalize the use of antimicrobials. In this survey, a cross-sectional study of 102 random contributing samples was performed. From January to March 2020. Knowledge and attitudes were assessed using a typical self-administered questionnaire. Descriptive analyzes were used to express the results. A total of 102 participants answered the questionnaire. Overall, collaborators have established good knowledge and positive attitudes toward antimicrobial resistance based on 13 knowledge questions and nine attitude statements. Gaps were identified in the knowledge of the possibility of addressing resistance through the discovery of a new drug (21.6%), the possibility of using antibiotics as an effective drug against viral diseases (36.3%) and the possibility of accelerate the treatment of diseases with antibiotics (38.2%). The majority of respondents (72.5%) agreed that antibiotic resistance induces serious global problems that affect public health. Furthermore, the majority of those interviewed (69.6%) believe that this phenomenon affects our health and that of our families. Similarly, (13.7%) of the participants totally agreed, while (65.7%) agreed that pharmacists played an important role in the appearance of this problem, and (37, 3%) of the participants fully agreed, while (58.8%) agreed that it is necessary to follow the recommendations and guidelines for life-saving antibiotics in the hospital. In contrast, 27.5% of the participants expressed a weak attitude towards the possibility of fighting antimicrobial resistance in their region through infection control practices by health professionals. Contributors in this study had good knowledge and positive attitudes toward antimicrobial resistance. Although the data is indicative of gaps in the knowledge of residents of the city of Al-Suwaria/Wasit province.
