Authors: Dasmasela Evangelista Militchia Christy , Sugianto Wahyu , Nur’aidha Amalia Cemara 
Published: September 2024

Microorganisms have various shapes, structures, and characteristics. This study uses the method of electrical impedance spectroscopy aimed at identifying and comparing the characteristics of Escherichia Coli, Salmonella Typhi, and Staphylococcus Aureus. Measurements from 1 Hz to 100,000 Hz show that Salmonella Typhi has the highest impedance value at low frequencies. In contrast, Escherichia Coli impedance decreases consistently, and Staphylococcus Aureus decreases sharply after 10 Hz. Significant changes are observed in the mid-frequency range of 100 Hz to 1000 Hz, with Salmonella Typhi showing the highest impedance values at 100 Hz compared to Staphylococcus Aureus and Escherichia Coli. At 100 Hz, Salmonella Typhi has the highest impedance value with a mass of 0,06 grams at approximately 39.000 Ohms, 0,08 grams at 35.000 Ohm, and 10 grams at 34.000 Ohm. This is followed by Staphylococcus Aureus, with a mass 0f 0,06 grams having an impedance value of 23.000 Ohms, 0,08 grams having a high impedance value of 31.000 Ohm, and 0,10 grams having an impedance value of 15.000 Ohm. Escherichia Coli, with a mass of 0.06 grams, has an impedance value of 9.000 Ohms, 0,08 grams with an impedance value of 5.000 Ohms, and 0,10 grams has an impedance value of 5.000 Ohms. Electrical Impedance Spectroscopy is effective for identifying and comparing Escherichia coli, Staphylococcus aureu, and Salmonella typhi as the intrinsic characteristics of bacterial cells more influence impedance than bacterial mass.

Erosi tanah adalah hilangnya tanah atau sebagian tanah dari suatu tempat ke tempat lain karena faktor air dan angin. Penggunaan lahan di lereng Gunung Argopura sebagian telah teralihkan menjadi tanaman semusim dan tanaman perkebunan, khususnya tebu. Terjadi perubahan, seperti pada musim hujan, air yang mengalir ke hilir menjadi keruh membawa lumpur tebal. Kondisi ini menandakan sedang terjadi erosi tanah. Penelitian ini bertujuan untuk mengkaji dan memprediksi tingkat bahaya erosi tanah di kawasan pegunungan Argopura dengan litologi breksi Argopura dengan menggunakan metode Universal Soil Loss Equation (USLE) dan sistem informasi geografis (GIS). Hasil penelitian menunjukkan bahwa wilayah pegunungan Argopura sebagian besar merupakan wilayah kategori berat, dengan kehilangan tanah sebesar 180–480 ton/ha/tahun dan sebaran luas mencapai 1.502,49 ha (37,59%). Sebaran pada kategori berat terdapat pada penggunaan lahan jenis tegalan dan sawah, baik irigasi maupun tadah hujan. Potensi erosi tanah kategori sangat berat dengan laju kehilangan tanah >480 ton/ha/tahun meliputi area seluas 508,52 ha (12,72%). Kategori sangat berat antara lain disebabkan oleh penggunaan lahan hutan dan lereng yang curam sehingga budidaya yang dilakukan pada lahan tersebut perlu diganti dengan konservasi tanaman yang dapat mengurangi erosi tanah.

The purpose of the work is to determine the structure and mechanical properties of sintered copper (including those containing carbon nanotubes) after intensive plastic deformation by torsion. Methodology: The research objects are samples of copper powder PMS-1 (GOST 4960-75), copper powder with a 45 microns’ fraction, copper powder PMS-1 with the carbon nanotubes addition 1 % by weight, manufactured by double pressing − sintering, with a 700 MPa final pressure, temperature of 950 °C, and subjected to intensive plastic deformation by torsion on a Bridgman anvil. The structure is investigated using a Tescan Micra 3 LMU scanning electron microscope. Micromechanical tests were carried out using the “Micron – Gamma” device. Originality. At first, the microstructure and mechanical properties of sintered copper and nanomaterial “copper − carbon nanotubes” after intensive plastic deformation by torsion were investigated. It has been established that intensive plastic deformation by torsion significantly affects the sintered copper samples structure and mechanical properties. The sintered copper grain shape changes from approximately spherical to elongated in the deformation direction, and the grain size decreases by 5−7 times. In the case of “copper + 1 % CNT” nanomaterial intensive deformation, the grain refinement effect is significantly less pronounced. A significant increase in the mechanical properties of sintered copper during intensive plastic deformation has been established. The highest indicators were obtained for the “copper + 1 % CNT” nanomaterial. Practical value. The results of the work can be used in the manufacture of copper products for electrical and thermal purposes with increased wear resistance.

The relevance of the work. The results is theoretically substantiated and experimentally confirmed the possibility of obtaining a dry additive-retarder of gypsum setting based on lime and polyvinyl acetate dispersions due to the formation of polyvinyl alcohol and salts of calcium acetate in the result of alkaline hydrolysis of polyvinyl acetate dispersion (PVAD) with the slaked lime in hydrated lime. The results of the work implemented in the production of dry gypsum mixes. Purpose. The development of dry building mixes based on gypsum and time increase of time of their conformance through adding of complex additives on the basis of burnt lime and polyvinyl acetate dispersions [PVAD]. Methodology. The study used standard research techniques to determine physical and mechanical properties of gypsum binders and quality of complex additives according to ДСТУ Б В.2.7-82:2010, ДСТУ Б В.2.7-23-95, ДСТУ Б В.2.7-171:2008. Study of phase composition of materials, micro – and macrostructure was carried out by x-ray diffraction, electron and light microscopy. The results. The influence of the main components of the additive (polyvinyl acetate dispersion and lime) on the properties of hemihydrate gypsum is investigated. The chemistry of the interaction of components of the complex additive, according to which the result of alkaline hydrolysis of polyvinyl acetate is formed: polyvinyl alcohol, a feature of its molecules structure is the presence of hydrophilic OH−groups and the hydrophobic component − a hydrocarbon radical. The hydrophilic part of the molecule being ion adsorbed on the surface of the particles of the binder, forms a monomolecular layer that is oriented with the hydrophobic part of the gypsum particles. It is also possible the formation of calcium acetate Ca(СН3СОО)2, which increases the concentration of calcium ions in solution. The combined effect of hydrolysis products significantly reduce the solubility of hemihydrate, the rate of formation of crystallization centers, due to the slowing effect of these supplements.

One of the efforts to prevent and stop the incidence of infection in health care facilities is to break or eliminate the chain of transmission of infection consisting of 6 components (infectious agent, reservoir, portal of exit, transmission method, portal of entry, suscptible host). Prevention can also be done by observing the risk factors and characteristics of the patient. The purpose of the study was to analyze factors that affect the incidence of HAIs (healthcare associated infections) in the inpatient of RSUD dr Iskak Tulungagung. The research design is in the form of quantitative research with case control analytical observational research methods with a retrospective approach. The research samples were some employees at RSUD dr. Iskak Tulunggung Regency as many as 83 case groups and 83 control groups with sampling techniques using the simple random sampling method. The results showed that the factors that influence the incidence of HAIs at RSUD dr. Iskak Tulungagung is an invasive action, a type of microorganism germ and the length of the day of treatment. While the most dominant factor affects the incidence of HAIs at RSUD dr. Iskak is the length of days of treatment with an OR of 5.256, meaning that the factor of length of days of care is 5 times more influential on the increase in the incidence of HAIs at RSUD dr. Iskak Tulungagung. Providing appropriate prophylactic antibiotics, balanced nutrition and vaccination to patients are steps that must be taken to help the patient's immune system remain in a state of being able to fight infection.

Cancer is a public health problem in Indonesia with a prevalence of 136.2/100,000 population. One of the most common cancers, especially in women, is breast cancer. The highest incidence of breast cancer in women is 42.1 per 100,000 population with an average death rate of 17 per 100,000 population. One of the countermeasures for breast cancer is case finding with early detection carried out through clinical breast examination (CBE) and breast self-examination (SADARI). One of the features developed by Postgraduate students of the Institute of Health Sciences STRADA Indonesia is a breast cancer early detection application called “MamoApp”. In this community service activity, 2 aspects of activities will be carried out in the Dharma Wanita group of DLHKP office in Kediri city. The first activity is to conduct a socialization in the form of providing health counseling to the Dharma Wanita group about SADARI techniques, the second activity will be carried out early detection of breast cancer using the MamoApp android application. Mamoapp application contains an educational video on awareness examination, then respondents fill out a questionnaire to detect the presence or absence of symptoms of breast cancer, the time used for filling in is approximately 10 minutes. From the results of filling out the questionnaire through the MamoApp application, we will immediately know the conclusion of the examination results, namely: “Indicated Cancer” or ‘Not Indicated Cancer’, so that participants can immediately find out whether the person concerned is indicated by breast cancer or not. From the results of the questionnaire of 38 participants, there were 2 participants who indicated breast cancer and 36 participants did not indicate breast cancer. Participants who indicated breast cancer by the facilitator were advised to do a further examination to the doctor for a more detailed examination.

DIAGNOSTICS OF THE DEVELOPMENT OF INFORMATION AND DIGITAL COMPETENCE OF FUTURE OFFICERS
Authors: Burtovy Roman 
Published: September 2024

Formulation of the problem. Today the problem of developing information and digital competence (IDC) of future officers in the context of non-formal education and the problem of designing a diagnostic apparatus to measure such development is relevant. The paper aims to develop a diagnostic apparatus (criteria and indicators) to measure the development of information and digital competence of future officers
Methods. To achieve this goal, we used the analysis and generalization of scientific sources, structural and logical analysis to identify and substantiate the indicators of the development of the IDC of future officers, as well as content analysis and comparative analysis to characterize the levels of development of the IDC of future officers.
Results. To assess the levels of development of the IDC of future officers, the criteria (motivational and value, cognitive and activity) and the relevant indicators (the presence of motives, value attitudes for self-development, knowledge about IT & DT in general and in the industry, the ability to use DT and IT to solve professional problems) have been determined. The qualitative assessment of the indicators made it possible to characterize the levels of development of future officers' IDC. Each level (low, medium, and high) reflects a different degree of IDC development, and, accordingly, a different degree of development of motives, knowledge, and skills to use IT and DT in professional activities. A low level may be sufficient for basic tasks, but medium and high levels are critical for managing complex operations and adapting to the performance of professional duties.
Conclusions. This diagnostic apparatus has been developed, and levels of development of future officers' information and digital competence have determined the ability to use modern technologies to perform official duties effectively. With the help of the diagnostic apparatus, it becomes possible to test the effectiveness of pedagogical models of future officers' IDC development.
