ON “CORRECT” CLASSIFICATION OF TASKS OF FORENSIC EXAMINATION
Authors: Humenskyi Olexandr
Published: August 2022

To date, the issues of classification of the tasks of forensic examination are debatable, there are several points of view on the problems covered in the article, and all of them are related to the differentiation of these tasks, that is, ultimately, to the establishment of the boundaries of the methods that are used to solve them.

Classification of expert tasks is conducted on the basis of the “vector of induction of expert tasks” (hereinafter referred to as VIET), which is directed from the most “private” task of establishment of individual identity to the most universal task of establishing causative connections of the explored objects and phenomena with the purpose of establishment of a mechanism of an incident; as well as from the establishment of particular features of an individual object, as the basis for achieving the goal of the study, to the determination of the maximum possible set of all features and properties of several studied objects and their relationships.

The division of tasks of judicial examinations based on VIET enables their “correct” classification, in that sense, that vector is those “rule”, by which monosemantic classification of tasks is real depending on their position on the scale of this vector and, as a result, monosemantic attributing of any concrete expert task to the certain kind.

Certain by us: 1) multitude set of identification tasks with a subset of group identification of the first type; 2) classification tasks; 3) group identification of second type (classification and diagnostic tasks); 4) diagnostic (with a subset of causally-diagnostic); 5) situational tasks of forensic examination.

The following definitions have been adopted.

Identification is the process of establishing (excluding) the identity of the identified and identifying objects by a combination of general features. Considering the influence of the ratio of general and features when making a decision about identity, we dwell on the position that identification can be individual and group.

Expert diagnostics is a scientific method of cognition, the essence of which is to recognize the typical state of the diagnosed object, as well as the presence or absence of a deviation from the norm.

Classification is the assignment of an object to one of the established classification groups. The group, judging from the above definition, must be strictly defined.

Classification can be based on groups of different degrees of generality, but it does
not cease to be a classification.

Situational examination – a type of examination that establishes the mechanism of an incident in its tracks, objects, and environment and is implemented as part of comprehensive studies.

Key words: classification of tasks of forensic examinations, vector of induction of expert tasks, identification, classification, group identification of second type, diagnostics, situational tasks.
Efecto de tres técnicas de polinización sobre el rendimiento de Palma Aceitera (Elaeis guineensis Jacq.) de 4 años
Authors: Huaringa Daniel
Published: August 2022

La palma aceitera es un cultivo con un creciente aumento en su producción, la deficiente producción de frutos durante los primeros años de este cultivo se debe a la poca presencia de inflorescencias masculinas y por ende una baja población de insectos polinizadores.  El objetivo de este estudio fue comparar técnicas de polinización que permitan incrementar el rendimiento de la palma aceitera durante sus primeros 4 años de producción. Se evaluaron tres técnicas de polinización para mejorar rendimientos productivos: polinización natural, polinización entomófila dirigida y polinización asistida. Se asignó 5 repeticiones por tratamiento y el diseño usado fue un DCA, para el análisis de los datos se usó el software estadístico Minitab17. Las variables consideradas fueron: peso de racimo, número de frutos normales, número de frutos partenocárpicos rojos y blancos, y número de frutos abortados. El análisis estadístico indico diferencias significativas (p<0,05) para las variables peso de racimo, número de frutos normales y número de frutos partenocárpicos blancos; mientras que para las variables número de frutos partenocárpicos rojos y número de frutos abortados no se hallaron diferencias significativas (p>0,05). En el análisis comparativo de promedios el tratamiento con polinización entomófila dirigida mostro ser superior al resto. Los resultados indican que la polinización entomófila dirigida puede ser la solución para mejorar el bajo rendimiento de la palma aceitera durante sus primeros años de producción. En conclusión, en el presente ensayo la polinización entomófila dirigida mejoro los parámetros productivos en una plantación joven de palma aceitera.

This research uses the historical method by conducting a study of a number of libraries, especially the De Sumatra Post newspaper and is supported by other references from books, magazines, journals which the author considers appropriate and credible. The findings of this study were that in the beginning, cinema was only intended by the elite and Europeans. However, after the Ethical Politics the film can be enjoyed by everyone. Films reached Medan in the late 19th century. The first cinema that was built in Medan was De Oranje Bioscoop in 1889. Then it was followed by other theaters that enlivened the entertainment business in Medan. In its journey, this industry has gone through many challenges of the times. The cinema comes as a cheap and quality new entertainment facility. In addition, the cinema is also a meeting place of various cultures and social status.Keywords: Film history, cinema, entertainment business.
Kebijakan Umar ibn Abdul Aziz dalam Pemberantasan Korupsi
Authors: Ali Muhammad Nasihudin
Published: August 2022

Bani Umayah is a dynasty founded by Muawiyah ibn Abu Sofyan. The name Umayyah is addressed to Umayyah ibn Abd Syams ibn Abdi Manaf, who was a Quraish figure during the era of ignorance. The reign of this dynasty experienced peace during the time of Umar ibn Abdul Aziz. He succeeded in uniting the warring groups. In addition, Umar ibn Abdul Aziz managed to eradicate the corruptors. This can be seen when Umar II fired offensive officials, one of which was the Governor of Khurasan, Yazid ibn Muhallab who committed evasion of provincial taxes. Umar II also replaced the second sermon at Friday prayers which previously denounced Ali ibn Abu Thali and his family, and replaced it with a verse of the Koran. The realization of peace and security of the people is the priority of Umar ibn Abdul Aziz rather than the expansion of power and the State. Research used by the author is to use library research, namely research whose data sources are taken from books and writings.

Published: August 2022

This study aims to look at the history, myths, and community perspectives regarding the Fort Putri Hijau site located in Deli Tua, Deli Serdang Regency. Putri Hijau Fort is a natural defense fort that is thought to be a relic of the Aru Kingdom. However, the existence of this site is often associated with history and myths that are still believed by the local community. This research is included in the type of field research using historical research methods. The results of this study indicate that the existence of the Putri Hijau Fort site as a cultural heritage is not widely known by the general public, let alone the surrounding community. People are much more aware that the site is just a place for bathing tours without any historical, mythical, and cultural heritage values in it. In addition, not many people know that the site is a former relic of the Aru Kingdom. Even some people from the age range of around 20-50 years who live around the location of this site, do not know about the existence of the Aru Kingdom. Some of them only know a few myths about the beauty of Putri Hijau and the greatness of Putri Hijau's brother named Mambang Yazid which has been told from generation to generation.

Published: August 2022

Key Points

A pilot randomized controlled trial of integrated palliative and nephrology care in patients with CKD stage 5 not on dialysis is feasible.

A pilot randomized controlled trial of integrated palliative and nephrology care in patients with nondialysis CKD 5 is acceptable.

Participants in the integrated care arm had lower symptom burden scores at the end of the trial, whereas the control group had higher scores.

Background

There has been a call by both patients and health professionals for the integration of palliative care with nephrology care, yet there is little evidence describing the effect of this approach. The objective of this paper is to report the feasibility and acceptability of a pilot randomized controlled trial testing the efficacy of integrated palliative and nephrology care.

Methods

English speaking patients with CKD stage 5 were randomized to monthly palliative care visits for 3 months in addition to their usual care, as compared with usual nephrology care. Feasibility of recruitment, retention, completion of intervention processes, and feedback on participation was measured. Other outcomes included differences in symptom burden change, measured by the Integrated Palliative Outcome Scale–Renal, and change in quality of life, measured by the Kidney Disease Quality of Life questionnaire and completion of advance care planning documents.

Results

Of the 67 patients approached, 45 (67%) provided informed consent. Of these, 27 patients completed the study (60%), and 14 (74%) of those in the intervention group completed all visits. We found small improvements in overall symptom burden (−2.92 versus 1.57) and physical symptom burden scores (−1.92 versus 1.79) in the intervention group. We did not see improvements in the quality-of-life scores, with the exception of the physical component score. The intervention group completed more advance care planning documents than controls (five health care proxy forms completed versus one, nine Medical Orders for Life Sustaining Treatment forms versus none).

Conclusions

We found that pilot testing through a randomized controlled trial of an ambulatory integrated palliative and nephrology care clinical program was feasible and acceptable to participants. This intervention has the potential to improve the disease experience for those with nondialysis CKD and should be tested in other CKD populations with longer follow-up.

Mathematical model and method of solving the generalized Dirichle problem of heat exchange of a cut count
Authors: Berdnyk M.
Published: August 2022

The choice of thermal protection of the rocket fairing is approached with special care, because the fairing must protect against aerodynamic heating, radiation, temperature changes. Currents with large Mach numbers are accompanied by gas-dynamic and physicochemical effects. When flowing around the blunt body, a shock wave is formed, which departs from the body, remaining in the vicinity of the frontal point almost equidistant to its surface. Physico-chemical effects are due to rising temperatures caused by the inhibition of gas by the shock wave. At the same time there is a transition of kinetic energy of a stream rushing in thermal, fluctuating degrees of freedoms of gas molecules are excited, its dissociation and even ionization begins. Therefore, among the problems of great theoretical and practical interest is the problem of studying the temperature fields arising in the fairings for missiles in the form of a truncated cone, which rotate around its axis, given the finiteness of the rate of heat propagation. In the article the mathematical model of calculation of temperature fields for a truncated cone is constructed for the first time which approximately models distribution of temperature fields which arise in fairings for rockets, with taking into account the angular velocity and the final speed heat distribution in the form of a boundary value problem of mathematical physics for hyperbolic equation of thermal conduc-tivity with boundary conditions Dirichlet. A new integral transformation for a two-dimensional finite space is constructed, in the application of which the temperature field in the form of a convergent series is found. The solution found can be used to predict the possible value of thermomechanical stresses, to promote the correct choice of technological parameters, objective control, allows to identify ways to improve the thermal protection of fairings for missiles.

Published: August 2022

The irrigation process is one of the most important elements of technologies for growing crops on irrigated soils. The tasks of ensuring optimal soil water regime, eliminating gravita-tional water losses outside the zone of active moisture exchange and promoting the fullest use of plants of bioclimatic potential of the region require modeling of soil moisture dynamics in the process of wetting, as well as structures and technologies related to irrigation facilities. Soil moistening in the south of Ukraine is carried out mainly by sprinkling with the use of a Frigate sprinkler, which is largely close to the natural processes of moisture in soil structures, especially with the use of the latest Xi-Wob sprinklers, which provide uniform irrigation and uniform droplet size. The aim of the article is to develop a model of soil moisture change, which will determine the moisture content in both the root and near-surface layers of the soil and prognoses the movement parameters of the "Frigate" sprinkler elements. The designs of sprinklers currently available allow to provide uniform intensity of spraying of drops on all working area of "Frigate" sprinkler, therefore it is possible to choose a separate point for modeling. The data obtained for one point can be extended to the entire work area. The Darcy equation is used to mathematically describe the movement of water in the soil. The finite difference method was used to solve the Darcy equation based on the initial and boundary conditions. Assuming that within each soil element the humidity changes linearly, and replacing the partial derivatives of moisture in depth and time with the analogues, the discretized model of soil moisture dynamics in the final differences was obtained, which allows you to predict moisture at any time due to hydro-soil characteristics in previous time and boundary conditions. Discretization of the Darcy equation made it possible to obtain a model of the dynamics of the humidity of the root layer in the space of states. It turned out to be nonlinear due to the hydrophysical characteristics of the soil and was linearized by transformation into the Taylor series. The developed mathematical model of soil moisture change in the space of states allows to determine the moisture content in both the root and near-surface soil layer depending on its hydrological characteristics, type of cultivated plants, volume of water entering the fields from irrigation systems or in the form of random precipitation used to predict the movement parameters of the "Frigate" sprinkler elements.
Semantic analysis of the basic concepts of research on the construction of an information-analytical system for the training of scientific personnel
Authors: Rostoka M.
Published: August 2022

The relevance of support for research on the methodology of building information and analytical systems is determined by the separation and justification of basic concepts. In this context, based on view of the relevance of the topic of the article on the results obtained analytically, before proceeding to the practical aspects of building any information-analytical system, given the transdisciplinarity of scientific knowledge, it is always appropriate to conduct structural-logical or semantic analysis terminology. This makes it possible to clarify the essence and content of the basic concepts of research and to outline the vector of further research. It is noted that in the conditions of modern information communications all objects of information-analytical interaction, regardless of their origin, are directly or indirectly interconnected. The purpose of the research is to provide basic categorical-conceptual support for doctoral research on the methodology of building information and analytical systems. In this sense, the methods of content analysis, semantic and comparative analysis, ontological modelling, etc. were used, which allowed identifying several types of approaches to determining the amount of information exchanged by objects in the process of information interaction: algorithmic, entropic, combinatorial, ontological, semantic, synergistic, transdisciplinary and pragmatic. The results and conclusions of the research are in the range of issues that allow us to understand the essence of the definition of «Information-Analytical System»; the semantics of the terms «Information», «Information Object», «Information Environment», «Information Space», «Information-Analytical Interaction», «Semantic Environment», etc.; the special nature of information as such, which distinguishes it from matter and energy, is emphasized; it is noted that information exists only in the presence of its carriers, which have a material and energy form; the relationship between the concepts of «Information Environment», «Information-Analytical Field» and «Information Space» is revealed, which is derived from the content of the basic concept of «Information». The ontological approach as a basic tool of semantic (informational) analysis is studied (within which it is possible to calculate the semantic similarity of semantic interpretations of text tokens in relation to the immediate semantic environment, i.e. context); it is noted that the construction of ontologies is based on the fixation of logical constructions that contain dictionaries of terms of the thematic area and on the description of the definitions of these terms, their theoretically possible and impossible semantic connections; it is noted that the basis for building an ontology can be user requests; the mathematics of the process of ontological modeling is briefly presented. The current definition of «Information-Analytical System» based on the results of semantic analysis is given.

Modern technologies for creating and maintaining web applications are focused on platforms that allow you to effectively manage the content and data coming from visitors. One of the popular technologies for creating web pages with code snippets running on a server is PHP (Personal Home Pages). This technology is based on the use of CGI applica-tions that interpret embedded HTML page code in a scripting language. The main feature of the PHP language is its practicality. PHP provides the programmer with a tool to quickly and efficiently solve problems. It is characterized by exceptional flexibility to the needs of the de-veloper. When teaching the course of study "Software tools for creating server-side web applica-tions" the main attention is paid to the study of PHP language. Students are also introduced to the SQL language and the MySQL database management system. A separate topic is the study of AJAX technology. The AJAX-based approach allows you to increase the intensity of data exchange between the user and the server application, thereby reducing server downtime and, most importantly, improve the friendliness of the interface. Due to the asynchronous interaction of the interface with the server part, the user opens up new facets of convenience. Several lectures are devoted to the basics of information security. Web application in-formation security threats (cross-site scripting (XSS), SQL injection, CRLF attack, XXE, CSRF, DDoS attack), ways to prevent the above threats; search for web resource vulnerabilities, security analysis tools web applications. During the lectures, attention is paid to the correct structure of sites, taking into account the principles of SEO and the basic principles of Usability - a qualitative assessment of the sim-plicity and comfort of working with the site. Thus, the educational course "Software tools for creating server web-applications" is designed to teach students to develop their own sites and web-applications and use them in professional activities. Prospects for further improvement of teaching the course of study we see in the supplemented with modern material on web-technologies that are developing rapidly.

Published: August 2022

Formulation of the problem. An actual problem when creating web resources is the test-ing of the designed design, which is the direction of testing the user interface. This paper con-siders ways to automate the analysis of the interface of web pages in terms of visual perception of man. The aim of the work. The aim of the work is to improve the quality of automated testing of the graphical user interface based on the use of methods of analysis of color digital images and detection of graphic objects. Methods of selecting objects on digital images. The traditional method of segmentation is described – threshold binarization, which results in a binary image. The JSEG algorithm is more advanced. According to this method, instead of estimating the parameters of the texture model, the homogeneity of each image fragment is checked, which leads to a reduction in the amount of computation. Website interface evaluation methods. In order to qualitatively evaluate the user interface, it is necessary to identify the basic principles on which designers rely when designing interfaces. Basic principles of interface construction: shape, size, brightness, color, direction, location. Determining the brightness characteristics of the image. To estimate the brightness pa-rameters, you can use the estimation of the image histogram, which displays the brightness value. The optimal type of brightness histogram is the normal distribution. Determining the number of primary colors in the image. Performed by constructing a histogram for an indexed image on a given color map. It is optimal to use no more than 3 primary colors. Selectionobjects in the image. The methods of image segmentation described above are implemented and the imperfection of these methods is shown. The application of the JSEG algorithm gave a more positive result, but requires additional adaptation to our tasks. Conclusions. The study and comparative analysis of digital image processing methods to automate the process of assessing the quality of the graphical user interface. It is concluded that the application of the classical approach to image segmentation did not give the desired result for image analysis of web pages, namely there are problems of inability to separate adjacent graphics at the threshold binarization, and combine text characters into one block. The JSEG algorithm includes color quantization and spatial segmentation operations, due to which the result of object selection is better, but still requires further settings.
Models of monitoring of self-like traffic of information and communication networks for attack detection systems

Published: August 2022

Autoregressive, fractal and multifractal models of network self-similar traffic are con-sidered, which allow to form an adequate reference model (template) of "normal" traffic and to detect traffic anomalies in attack detection and prevention systems. Models of fractal Brownian motion and fractal Gaussian noise were considered as models of fractal motions, because they have self-similarity and long-term dependence properties that correspond to the properties of experimental data, as well as the possibility of their analytical interpretation. When evaluating and identifying processes for the implementation of autoregressive models use adaptive filters-approximators, among which there are neural network and neuro-wavelet. The following were used as multifractal models: a multifractal wavelet model with a beta distribution and a hybrid multifractal wavelet model in which the beta distribution is used on a coarse scale and the dis-tribution of point masses on an accurate scale By modeling as a result of adaptation and learning of models, autocorrelation functions, spectra and variances of model signals qualitatively correspond to the graphs of the experimental signal. In addition, the qualitative and numerical values of the characteristics of the model signals generally correspond to the characteristics of the experimental signal. In this case, beta multifractal wavelet models have a smaller error of determination of characteristics than hybrid multifractal wavelet models, and the relative root mean square error of approximation of the experimental signal using a neural network adaptive filter approximator does not exceed 0.046. Statistical verification by non-parametric criterion of signs allowed to establish the adequacy of experimental and model signals with a significance level of 0.01. Further research should be aimed at developing and using predictive models of self-similar traffic in attack detection and prevention systems, which will increase the efficiency of attack detection.

Published: August 2022

The problem of improving progressive and creating new technologies in metallurgy and foundry production is relevant for obtaining high-quality cast metal and castings. The microscopic and macroscopic properties of casting templates significantly depend on the thermophysical parameters of the casting system and the casting mold, namely, the width of the two-phase zone of melt solidification, the initial temperature of the melt, the cooling rate of the casting, the cooling gradient of the melt, and the temperature on the surface of the casting mold. In order to obtain a fine-grained metal structure. The article presents the results of experimental studies, indicating the fractal nature of structure formation in a two-phase zone of the solidifying metal melt. The thermodynamic statement of the non-stationary problem solidifying of binary systems is considered. Transfer equations are described that are adequate for media with fractal geometry. The mathematical apparatus for describing the curing process from the standpoint of heat and mass transfer in a two-phase zone and diffusion in fractal media is presented. It is shown that the mathematical apparatus of fractional calculation makes it possible to effectively describe the fractal nature of diffuse processes. The analysis of the thermal and mass transfer processes in the melt of the metal, which is in the rare state, and their description using the mathematical apparatus of fractional calculation, have been carried out.

Authors: C Arunan
Published: August 2022

Kapilar is a much-revered Sangam poet. He is also known as Kurinji Kapilar as he has highlighted the Thinai, Kurinji. The great Sangam literature contains many poems of Kapilar. Kapilar was mostly with the common people and rendered songs on their contributions to art, craft, cultural values and their living styles in tune with the nature.Instead of singing the praise of Chera, Chola and Pandya, the trinity of Tamizhagam, Kapilar rendered wonderful songs on the greatness of Paari, the ruler of Parambu land. Kapilar praised the humility and generosity of Paari. Paari’s kindness towards poets, artists and guests turned at his doorsteps was uncomparable. He was also full of compassion even towards creatures living around him. The greatest quality of sharing all his wealth with poets touched the heart of Kapilar who became the greatest admirer and bossom friend of him. Paari’s humanitarian gestures towards the downtrodden made Kapilar narrate the contribution of the lay- men to up- keep the Tamil Culture, language and values alive. The author of this research article articulates how significant it is to learn the socio-economic, cultural life of the commoners of Sangam period through the Puram songs of Kapilar.
Religious Beliefs in "Silambu"

Published: August 2022

Man is not only an animal that eats, dresses, and lives, but also an animal with religious knowledge. Only man, unlike animals, has discovered a superhuman power to protect himself from threatening evil and to obtain what he desires. How the ancient people came to think about religion is an unending debate among anthropologists and realists. He mentions that scholars like "Periluite" and others like "Thurkiyam" think that the fear that appeared in the people is the reason for the emergence of religion. The text says that there was a principle behind the fact that Veeduperu (Salvation), Meyporul (Reality), Illatthuravu (Give up material life), Vethanambikkai (Belief in Vedas), Nadukal Vanakkam (Salutation to Hero Stone), the number three, Veda and Velvi (Veda and Sacrifice), are considered to be religious as well as subjected to scrutiny and appropriate that being religious is wise. Therefore, Ilango has also indicated the state of meditation of the saints of Jainism. It can be seen in three places in Silapathikaram that the people of that time gave importance to the number three in their lives. Countless sounds are heard in the city of Madurai. Then it can be known that the Vedas have been used in a faith-based manner by the fact that they are recited and the sound is heard. During the Silapathikaram era, virtuous Brahmins lived all over Tamil Nadu. They recited the Vedas, made prayers, and performed their six types of activities, such as reciting, desiring, conducting prayers, and offering gifts. The Epic emphasises the excellence of the Vedas by praising the maadalan. "Gods are peerless warriors who do good." According to the Greek philosopher, Euchemerus, after the deaths of these heroes, the people began to worship them as gods. But he also accepts the worship of dead ancestors as the root cause of religion. Despite these differences of opinion, religion is a very deep subject that resonates with man's deep experiences. A place where the thoughts and dreams of billions of minds flash, explaining the religious beliefs of the Silapathikaram period.
Investigation of the potential of greenhouse post-harvest wastes for bioenergy production and utilization for heating and carbon dioxide application
Authors: Şen Burak
Published: August 2022

In this study, raw biomass feedstock characterization of greenhouse post-harvest residues of tomato, pepper, and eggplant has been investigated using the wastes of stem and leaves as a source of energy gained from palletization. The characterization was compared to both sawdust and the relevant ISO and EU pellet standards. The proximate and ultimate analyses results of all the tested feedstock materials have proven to be successful candidates for pelletizing and combustion process. The bulk density of tomato, pepper, and eggplant pellets were found to be 568 kg/m3, 575 kg/m3, 589 kg/m3, respectively, and the higher heating values of these produces were found to be 17.25 MJ/kg, 17.45 MJ/kg, and 17.80 MJ/kg, respectively. Based on the results, it is possible to generate 10 tons of waste per hectare capable of producing almost 50 MWh of heating energy. Furthermore, this waste could generate more than 6.5 tons of CO2 per hectare. The study results suggest that the heating energy potential and the amount of CO2 emitted could be used in greenhouses to support photosynthesis during low temperature and low solar radiation periods.

The steam turbine is one of the main components in the Geothermal Power Plant which acts as the prime mover is used to convert heat energy in steam into rotation energy. At PLTP X, steam is used to drive the turbine is in saturation conditions. The principle of the steam turbine is dry steam plant cycle. From July to August, it was known that there have been several decreases in generating power at Unit 2 at PLTP X. The efforts that can be done to overcome this problem is by turbine washing. This study aims to compare the performance of steam turbines based on thermal efficiency, isentropic efficiency and steam turbine generator power before and after turbine washing from the calculation results based on CEI/IEC 953-1, CEI/IEC 60953-3 and ASME PTC 6-2004 standards using the actual steam system operating parameter data collection, interviews and analysis. So that it gets an average increase in isentropic efficiency of 0,0564 %, thermal efficiency of 0,0082 %, the actual power generation of steam turbine is 162,72 kW and the largest power generation reaches 54.500 kW after the turbine washing steam rate of 7,5963 kg/kWh and the turbine heat rate of 3.607,3453 kJ/kWh.

Inside the electric car charger there is a controller where one of the components is the Disc Ceramic Capacitor (DCC) type SCF2E472M10 coated with epoxy powder EF150AB. The faster the charging, the higher the temperature, for that we need good performance on the capacitor layer. The method used in this study is to test the Pressure Cycle Temperature (PCT) with a temperature of 121 ° C, a pressure of 2 bar and a holding time of 48 hours and a Thermal Shock Test with a temperature parameter of -40 ° C to 125 ° C for each temperature change. 30 minutes for 100 hours, the number of test samples for each test is 20. From the test results, it was found that the average capacitance value on the PCT test was 4439.9 pF with a standard limit value of 3760 to 5640 pF, then the average value of Insulation resistance (IR) after the PCT test was 14183 Ω with the standard limit of the IR value of 10000 Ω. From these results it can be concluded that epoxy powder EF150AB is good for DCC coatings because the coating is resistant to low and high temperatures, which ranges from -40 ° C to 125 ° C.

Painting is a process to make a thin layer of paint over an object. Factors to beautify the results of painting on the vehicle body are given a layer of varnish. To produce a quality varnish coating, it is necessary to pay attention to the ratio between the varnish-solvent used and the drying method used. This study aims to determine the mixture of varnish - solvent (1:0,1 and 1:0,2) with a drying temperature method of 40°C, 60°C, and 80°C on gloss, thickness, and adhesion to the motor vehicle body. The lower the oven temperature, the higher the gloss and the thicker the coating. The best adhesion at the oven temperature of 40ºC and 60ºC on all varnish-solvent compositions. The higher of the solvent mixture would result glossier and less thickness of the layer form.

With the decrease in world oil reserves, energy savings have begun to be launched in almost all countries of the world. Indonesia has now become one of the crude oil importing countries, so efforts are needed to reduce dependence on oil and gas fuels. The sustainability of biomass gasification technology, especially in Indonesia, is highly guaranteed because of the abundant availability of biomass in Indonesia. The purpose of this study is to determine the performance of a 5 kW diesel generator against variations in loading with diesel fuel. The second is to know the performance of a 5 kW diesel generator against variations in loading with diesel fuel and rice husk syngas. Data collection on the performance characterization of the 5 Kw diesel generator set from syngas rice husks against variations in loading was carried out at the New Renewable Energy Engineering Laboratory. The loading carried out in this study was using a 5200 Watt halogen lamp. The power used in this study is only up to a maximum of 3200 Watt. The test result shows that the power generated by the generator is greater when using diesel fuel compared to using a mixture of diesel fuel with syngas. The value of the generator power for each loading variable increased when using low electrical load and decreasing when using high electrical load.
