Analisis Kesediaan untuk Membayar (Willingness to Pay) Kompensasi Pengembangan Kawasan Naturalisasi Sungai oleh Badan Usaha Milik Swasta: Studi Kasus DKI
Authors: Sanjaya R Bayu
Published: July 2022

Floor area ratio (FAR) is one of the aspects regulated legally in the detailed spatial planning process in Indonesia. The Special Capital Region of Jakarta is not an exclusion. Although the compensation procedure regarding excessing legally regulated FAR has been set out in the regional law in the form of river border area development and naturalization, the exact value of compensation has not been legally determined. The present research aims to measure and analyse the willingness to pay of the private companies in Jakarta for excessing FAR. Cross-tabulation analysis and ANOVA are employed to analyse the sample of 24 private companies located in river border areas in Jakarta. This study yielded several results: the willingness to pay of the private companies is lower than the offered value, there are variations in willingness to pay between the companies’ characteristics, and there is a significant difference in average willingness to pay between the companies which are willing to let the compensation value be set by the government and those which are not willing to do so. From the results, several policy implications can be recommended to the government

Published: July 2022

In order to provide accident free timber rafting on small and medium-sized rivers, it is necessary to consider in detail the features of ensuring the raft flexibility with all the necessary calculations. The research aims at developing an improved methodology for calculating the parameters that ensure the flexibility of a raft made of flat raft units. The raft flexibility is formed through the optimal interval between flat raft units, which directly affects the flexibility index. The minimum allowable interval between raft units depends on the length of guard rails in the section line: the guard rail laying along the section line convex side and the guard rail laying along the section line concave side. Length of the guard rails in the timber transportation unit will be determined by the minimum turning radius of the rafting course, the section line width, the length of flat raft units and the distance from the raft board to the guard rail. When determining the optimal interval between the flat raft units and the raft flexibility, it is assumed that the section line of flat raft units, regardless of a strong piling current, passes within the raft course dimensions, where the raft course axis coincides with the raft axis, and the flat raft units located between the 1st and the last flat raft units can move freely in the longitudinal direction. We have studied the dependences of the interval between flat raft solid units on the minimum turning radius of the raft course, the section line width and the length of flat raft units, using the proposed methodology for calculating raft flexibility. We have found that with increasing turning radius of the rafting course, the interval between the flat raft units decreases, and the raft flexibility index increases. The interval between flat raft units becomes larger as the width of flat raft units increases and the coefficient of raft section density decreases in this case. As the length of the flat raft unit increases, the interval between flat raft units increases; the coefficient of raft section density decreases.

Organizational and engineering models provide a formalized description of the construction process, including a list of operations, their sequence, description of the relationship between the operations, and the features of the work technology. Network models have the most complete mathematical description. However, a number of authors in their works point to serious shortcomings inherent in the network modeling of construction flow. The network model allows displaying accurately enough only the relationship of specialized traffic flows when the object is divided into sections equal in size to interchangeable grips. Such schedules are quite effective in planning and operational management of road works in a short planning period (decade or month). The adequacy of the real construction representation is violated when the network model is enlarged for long-term planning of the flow. The currently developed so-called generalized network models achieve process combination and continuity by introducing links between the operations, characterized by temporal parameters assuming any values, including negative values. However, the complexity of the mathematical description of these models still prevents their use in solving optimization problems. The research aims at developing a mathematical model and an algorithm for calculating the operational control of the groundwork volume during the construction of logging roads. A model of a complex object flow is proposed, where the flow operation time has a discrete nature. This condition is realized in the model by dividing the planned operation period of a complex flow into equal time intervals – scheduling intervals. The below described model of complex road construction flow can be presented on the basis of the scheduling task classification scheme and the analysis of existing economic and mathematical models and methods. The scheduling model developed for the purpose of determining the optimal groundwork for the road construction elements is a deterministic (at the 1st stage), discrete in time, engineering model with variable speeds of operations.

The paper studies the influence of geoecological factors on the content of phenolic compounds (PCs) in lichens of the genus Cladonia in the Velsko-Ustyansky and Kholmogorsky tectonic knots (TKs). Lichens were sampled from the test plots (TPs) laid out in the center of the knots and outside the knots (control). The geochemical situation, soil-climatic and environmental conditions in the zone of TKs influence the lichens chemical composition. It is found that the ash content of lichens growing in the center of the TK is 1.8–2.3 times higher than in the control, which indicates a significant accumulation of lithogenic elements in the lichen thallus in the tectonic fault zone. Lichens are exposed to multifactorial adverse effects (increased radiation background and heat flux, electromagnetic radiation, electric and magnetic fields, etc.) in the territory of TKs. This provokes excessive generation of active oxygen radicals and contributes to the rearrangement of lichen metabolism, changing the dynamics of accumulation of PCs and their biosynthesis. The content of the water-insoluble fraction of PCs in lichens was found to increase from the control point to the center of the TK, while the relative share of the water-soluble fraction of PCs in the total composition decreases. This is probably due to an increase in oxidative processes and a decrease in reductive processes in lichens under adverse conditions. The paper shows that the biosynthesis of PCs in lichens is most active in the spring-summer (April and July) vegetation period. The impact of geoecological factors enhances the biosynthesis of secondary metabolites of phenolic nature in lichens in the conditions of the TKs: usnic acid (UA) and atranorin. The content of UA in the composition of the water-insoluble fraction of PCs in lichens growing in the center of the TK is 1.5–1.7 times higher during the spring-summer vegetation period than in lichens growing outside the TK. The quantitative distribution of the water-insoluble fraction of PCs depends on the lichen thallus part and has a gradient character. Their content in the upper growing parts of lichens growing in the center of the TK and in the control is 2 and 1.7 times higher than in the old zones, respectively. Thus, PCs in lichens are active metabolites and their content in thallus can serve as a biomarker of the state of the environment.

The research aims at estimating phytomass reserves of northern taiga green-moss and sphagnum pine forests growing in the Komi Republic. The study was carried out in pine forests at the Zelenoborsk forest research station of the Institute of Biology of Komi Science Centre of the Ural Branch of the Russian Academy of Sciences (IB Komi SC UB RAS) in 2016–2019. We analyzed sample trees data and derived power equations of the dependence of the individual fractions weight on the stem diameter at the breast height (1.3 m) for the main forest-forming species (pine, spruce, larch, and birch) of green-moss and sphagnum forest are characterized by rather large phytomass reserves, 136–211 t/ha. While in sphagnum pine forests there are 89–96 t/ha of phytomass. Despite the admixture of other wood species, the leading pool is represented by pine trees, and the main fraction (46–56 %) is wood of stem. The input of stem wood and stem as a whole (bark and wood) is greater in green-moss pine forests compared to sphagnum pine forests, while the share of roots in these two types is approximately the same. Participation of tree crowns (needles/leaves and branches) in the total phytomass reserves of pine stands on automorphic soils is significantly lower (17 % on average) than in communities on semihydromorphic and hydromorphic soils (22 % on average). The relatively greater mass of needles and leaves resulted in a high LAI, which varied from 8.8 to 17.8 and from 7.7 to 9.8 ha/ha, respectively, in green-moss and sphagnum pine forests. We found a high reliable (R = 0.88; p = 0.004) relationship between LAI and the tree basal areas sum, whereas it is statistically insignificant with density and wood supply. The conversion factors were calculated to convert timber volume into phytomass reserves of both individual fractions and species as a whole. The presented data are useful for assessing the productivity of pine ecosystems in different growing conditions during forest monitoring (including remote sensing methods) and also when planning forest management measures in order to increase the productivity of pine forests.
Microbiota intestinal y modulación del tejido adiposo en la patogénesis de la obesidad
Authors: Leonario-Rodriguez Marcell , Saavedra Nicolás
Published: July 2022

The investigations carried out during the last century related to the description of the Gut Microbiota (GM) suggest a concrete relationship between its composition and the health of the host. Its deregulation called intestinal dysbiosis has been associated with different types of gastrointestinal, metabolic, oncological and even psychiatric diseases. Numerous reports that have described the condition of dysbiosis in obesity stand out, both in animal and human models of different age groups and regions of the world. In turn, the composition of the microbiome has also been associated with the different comorbidities of obesity, postulating that MI has an influence on adipose tissue (AT) dysfunction, understanding that it corresponds to the main modulator of the pathogenesis of obesity. However, it is not yet possible to establish a plausible mechanistic explanation. Currently, the use of multi-omics technologies, together with the evaluation of physiological variables, could provide us with a better understanding of the question raised. In view of this, this review aims to review the latest advances in understanding the influence of the intestinal microbiota on AT and its contribution to the mechanisms related to the pathogenesis of obesity. Among the main mechanisms identified, the evidence reports physiological links between the composition of GM and the modulation of inflammation, intestinal permeability and adipogenesis. The pathways involved derive from the influence of intestinal dysbiosis on the action of short-chain fatty acids, claudins, macrophages, oligosaccharides, among others. The mechanisms involved, mainly studied in animal models, should be considered for evaluation in future longitudinal and experimental studies in humans in order to obtain a better understanding of the implication of each mechanism in the global pathogenesis of obesity.

Hay que tener presente que, mediante la figura de la hipoteca, se sujeta directa e inmediatamente los bienes sobre que se impone, cualquiera que sea su poseedor, al cumplimiento de la obligación para cuya seguridad fue constituida. De forma más amplia, la hipoteca puede entenderse como el contrato en virtud del cual una persona llamada deudor hipotecario, constituye un derecho real sobre un bien generalmente inmueble, determinado y enajenable, a favor de la otra parte llamada acreedor hipotecario, para garantizar el cumplimiento de una obligación, sin desposeer al deudor del bien gravado y que le da derechos al acreedor, de persecución y en caso de incumplimiento de la obligación, de enajenación y de preferencia para ser pagado con el producto de la enajenación. En ese contexto, conforme la normativa civil panameña, medularmente pueden ser objeto de hipoteca: los bienes inmuebles, los derechos reales enajenables, con arreglo a las leyes, los bienes muebles susceptibles de determinación o individualización. Ahora bien, siendo el contrato de hipoteca solemne para su validez constitutiva, además de los requisitos comunes exigidos a los contratos conforme el Código Civil, es indispensable, que la escritura donde se constituya se inscriba en el Registro Público de la República de Panamá o institución específica cuando aplique sobre bienes no sujetos de inscripción en dicho ente registral.

Published: July 2022

El objetivo de este ensayo es hacer una revisión histórica del desarrollo de las ciencias y hacer una aproximación a las bases de la investigación científica. Se tiene una idea errónea al limitar la ciencia al conocimiento encerrado en las paredes de un laboratorio, o al remitirnos a algunas áreas del conocimiento, cuando es cierto que cada vez que el hombre, desde sus inicios empezó a formularse interrogantes sobre él mismo, y sobre el mundo que lo rodeaba, empezó a hacer y producir ciencia. Siendo así, los interrogantes, las indagaciones, la búsqueda, y las preguntas, el camino para grandes hallazgos que le han permitido al ser humano entender, entenderse, explicar y explicarse a sí mismo y a otros sobre asuntos existenciales y del porqué de las cosas. En este ensayo se esbozará como el hombre, como ser razonable, es capaz a través de la investigación de crear ciencia, por las capacidades innatas de observación, reflexión, e innovación que este tiene. No se debe ser científico para investigar, sino tener una capacidad y disposición crítica, metódica y una sensibilidad social para generar transformación no solo en la propia existencia sino también en lo que para muchos puede ser inalcanzable.

Tendencias y desafíos de los sistemas educativos para el siglo XXI
Authors: López Valencia Delia Liset
Published: July 2022

El presente ensayo analiza las tendencias de los sistemas educativos, como parte de un proceso que determina su importancia para afrontar cuatro desafíos de la educación en el siglo XXI. La internacionalización, la modernización y el aprendizaje de las emociones; son configuraciones teóricas básicas para comprender adecuadamente la revolución 4.0, el cuarto objetivo del desarrollo sostenible (ODS), el modelo STEAM (Science, Technology, Engineering, Arts, Math) y la transformación digital; como palancas para avanzar cualitativamente en la búsqueda de calidad, innovación y pertinencia. Lo más importante es efectuar dichas transformaciones de manera creativa, inteligente y sin perder de vista que el ser humano es el que aprende y el que piensa, que la pedagogía antecede a la tecnología, que las emociones no pueden dejarse al azar y que la educación no debe competir con los educandos en los terrenos de los dispositivos electrónicos, porque ellos en su calidad de nativos digitales caminan mucho más adelante que sus maestros, padres de familia e incluso que las mismas instituciones. La formación que se pretende desde estas perspectivas es un insumo conceptual, metodológico y práctico, para que la escuela ajuste sus modelos mentales, organizacionales, pedagógicos, didácticos y curriculares; con el propósito de fortalecer las competencias de los educandos, que mejoren sus procesos de interpretación, argumentación, razonamiento, autonomía, investigación e innovación; en un marco de creencias, valores, principios y presupuestos ontológicos y éticos de un alto contenido humanizador.
clima escolar como eje fundamental para el mejoramiento de la calidad educativa
Authors: Ruiz Gloria Mayerly
Published: July 2022

Cada vez es más importante prestar atención a los factores que inciden en el mejoramiento de la calidad educativa, de hecho, este aspecto se encuentra enmarcado dentro de las políticas educativas colombianas. Frente a ello, en este ensayo se relaciona a la calidad educativa con el clima escolar, entendido como el estado de la percepción generalizada que poseen los actores que componen toda la comunidad educativa dentro de un proceso complejo de interacción social y cultural. Para hacer frente a este relacionamiento, se ubica a la gestión escolar como un proceso de participación activo y constructivo de escuela, donde se pone de relieve la idea de comunidad educativa, permitiendo centrarse en elementos constitutivos importantes dentro de dicha gestión como la convivencia, la pedagogía para la paz, el rol del docente y del estudiante, además, de los procesos de enseñanza y aprendizaje donde se haga foco en el contexto sociocultural. En efecto, el mejoramiento de la calidad educativa desde las bases del clima escolar, está, por consiguiente, condicionado al reconocimiento tanto de las diferentes posibilidades que tienen las instituciones educativas dentro de su entorno sociocultural como del respeto por los procesos de maduración, relación interpersonal y planes de acción y fortalecimiento que deban tomarse colectivamente.

Yo empecé en esto en la secundaria; tenía catorce años, y de pronto sucedió. Era un virus esto del grafiti, acá en mi tierra Monterrey, México. Agarré unas letras de mi nombre y empecé a firmarme en mis libretas; de ahí brinqué a los baños de la secundaria, los cuales estaban “tapizados”. Fui practicando cuando, de pronto, ya estaba en la calle firmando con lo que tuviera al alcance: crayones industriales, pintura de zapatos y, finalmente, con mi compañero fiel, pintura en aerosol. Fue por allá, en 1994.

Desafortunadamente me metí en muchos líos, y tuve que dejarlo tres años después. Pero seguía practicando en libretas, en la tierra que se queda en los vidrios de los coches y así hasta que, después de tantas cosas que pasaron en mi vida, un día estaba pintando un casco de motociclista, ya que a eso me dedico, y se me ocurrió hacer una firma en el patio de mi casa; pero hablo de mi casa, no la de mis papás, y me entraron las ganas de volver a hacerlo. Para entonces ya había pasado de los dieciocho años; recuerdo que fue en 2015. Fui dándole poco a poco, regresando a las calles. Ya no había crayones industriales, ni pintura de zapatos; ya era pura pintura en aerosol, pues un adulto con gustos de niño, imagínense, y pues ahora ya tengo casi siete años en esto, y aquí seguimos, dándole color a la ciudad.
Use Of Micro-Void Content Growth Rates To Validate And Add Value To Electrical Insulation Tan-Delta Aging Testing
Authors: Horvath David A. , Hostetter Greg M.
Published: July 2022

Our research as well as others has shown that micro-void content in electric insulation polymers grows in a way that can be correlated to the degree of aging. Specific results of our experiments combined with research by others have led us to conclude that a promising technique for predicting remaining life in electric cable insulation, based on micro-void content and proximity to void limiting parameters, can be developed. This approach involves use of acoustic or optical microscopy to establish an estimate of void content in polymers by determining micro-void sizes and density. Separate research is used to establish limiting values for percent void content correlating to material failure. The mode of failure varies depending on the applied voltage regime. For example, at medium and high voltage levels, partial discharge detection can be considered indicative of pending end of life. Whereas for low voltage regimes, brittleness to the point of cracking susceptibility would allow the potential for moisture ingress and shorting and can be considered end of life. It has been separately shown that void growth rate is a function of temperature and radiation dose rate both during normal and nuclear accident conditions and is predictable based on the known polymer chemical degradation equations, which produce gaseous products in the form of oxygen, water vapor, carbon dioxide, and carbon monoxide. Thus if end of life void content is known, the degree of void content growth occurring during a design basis accident is properly accounted for, and void content growth rates during normal temperature and radiation conditions are considered, then remaining life in electrical insulation can be accurately predicted. In recent years, several techniques have been proposed to assess electrical insulation aging. One of the more promising approaches for use with medium voltage cable is the tan-delta technique. This paper will demonstrate how the mirco-void content approach can be used to validate other techniques such as tan-delta and add additional meaning and value not otherwise available from tan-delta alone.
Nuclear Fuel Modelling During Power Ramp
Authors: Cantini Federico , Adorni Martina , D’Auria Francesco
Published: July 2022

Fuel rods operating for several years in a LWR can experience fuel-cladding gap closure as a result of the phenomena due to temperature and irradiation. Local power increase induces circumferential stresses in the cladding as a result of the different expansion in the cladding and the pellet. In presence of corrosive fission products (i.e. Iodine) and beyond specific stress threshold and level of burnup, cracks may grow-up from the internal to the external cladding surface, causing fuel rod failure. The phenomenon, known as pellet cladding interaction-stress corrosion cracking PCI/SCC, or PCI, has been identified as a problem since the 70's. The PWR Super-Ramp experiment (part of OECD/NEA “International Fuel Performance Experiments (IFPE) database”) twenty eight fuel rods behaviour has been simulated using TRANSURANUS code version “v1m1j11”. Two sets (“Reference” and “Improved”) of suitable input decks modelling the fuel rods, based on the available literature are used to run the simulations. Focus is given to the main phenomena which are involved or may influence the cladding failure. Systematic comparison of the code results with the experimental data are performed for the parameters relevant for the PCI phenomenon. Sensitivity calculations on fission gas release models implemented in TRANSURANUS code are also performed in order to address the impact on the results. The results show the ability of TRANSURANUS version “v1m1j11” in conservatively predicting the rods failure due to PCI in PWR fuel and Zircaloy-4 cladding. Increased availability of experimental data would help to perform a deeper analysis.
Liquid-salt-cooled Reactor Start-up with Natural Circulation
Authors: Gros Emilien , Petrović Bojan , Grgić Davor
Published: July 2022

The Liquid-Salt-Cooled Very High-Temperature Reactor (LS-VHTR) was modeled using the neutronics analysis code SCALE6.0 and the thermal-hydraulics and kinetics modeling code RELAP5-3D with objective to devise, analyze, and evaluate the feasibility and stability of a start-up procedure for this reactor using natural circulation of the coolant and under the Loss Of Offsite Power (LOOP) conditions. This Generation IV reactor design has been initially developed by Oak Ridge National Laboratory and studied by researchers worldwide for almost a decade. While neutronics and thermal-hydraulics analyses have been previously performed to show the performance of the reactor during normal operation and for shutdown scenarios, no study has heretofore been published to examine the active or passive start-up of the reactor. The fuel temperature (Doppler) and coolant density coefficient of reactivity of the LSVHTR were examined using the CSAS6 module of the SCALE6.0 code. Negative Doppler and coolant density feedback coefficients were calculated. Two initial RELAP5 simulations were performed to obtain the steady-state conditions of the model and to predict the changes of the thermal-hydraulic parameters during the shutdown of the reactor. Next, a series of step reactivity additions to the core were simulated to determine how much reactivity can be inserted without jeopardizing the safety and stability of the core. Finally, a start-up procedure was developed, and the restart of the reactor with natural convection of the coolant was simulated. The results of the simulations demonstrated the potential for natural circulation start-up of the LS-VHTR.

Any mechanical system can easily be analyzed with the help of proper designing or modeling. All kinematical constrains are also been considered at the time of modeling. Generally the traditional dynamical differential equations are solved to predict the nature of the system. In this work, some typical types of dynamical mechanical system in taken into consideration and further the dynamical equations are being solved using ‘Series Solutions Technique’ for the analysis of the nonlinear system. The solution is consisting of two sections. Using frequency response analysis via simulation, which section of the solution is more suitable or effective for the designing purpose has also been explained in detail. Finally, the local stability analysis of the entire system is studied in detail with proper numerical simulation.

The Internet of Things (IoT) or Eye Tracking Knowledge (ETK) has a major impact on educational institutions. Education institutions are adopting the IoT ecosystem and implementing a variety of strategies, like augmented reality and cloud computing. While the corona virus has had a global influence on education and the education-based sector, it is commonly accepted that until the corona virus is eradicated, drastic adjustments in the education sector are needed. The economy has been the most affected by Lockdown, but we cannot ignore the influence on education, as the traditional education that Lockdown provided to students has now been completely shut down someplace. Online education has now become a vital aspect of the education system in the modern world because of modern scientific and technical advancements. Prior to the Covid-19, however, online education in the most region of India was implementing continuously but it became mandatory due to the havoc of pandemic. Meanwhile, there are difficulties and challenges have been facing higher education sectors, notably in Uttarakhand universities, in successfully sustaining online education. Considering this, present study aims to supply insight into the influence of Covid-19 on the teaching and learning processes of Pharmacy students. According to the findings of the study, the academic institution met multiple issues in terms of digital platform, problems with practical tests administered via online mode, evaluation, examination etc. Authors are concluding the relation between the IOTs aided online and flipped classroom when university resumed. Certainly, this analysis guides us for the future preparation related to such adverse condition in education system. Keywords: Internet of Things, Covid-19, virtual learning, evaluation, lockdown

We modeled photometric observations of mutual events (eclipses and occultations) between the components of the binary near-Earth asteroid (65803) Didymos, the target of the Double Asteroid Redirection Test (DART) space mission, which were taken from 2003 to 2021. We derived parameters of the modified Keplerian mutual orbit (allowing for a quadratic drift in the mean anomaly, which is presumably caused by an interplay between the BYORP effect and mutual tides, or by differential Yarkovsky force) of the secondary, called Dimorphos, around the Didymos primary and estimated its diameter. The J2000 ecliptic longitude and latitude of the orbital pole are 320.°6 ± 13.°7 and −78.°6 ± 1.°8, respectively, and the orbital period is 11.921624 ± 0.000018 hr at epoch JD 2,455,873.0 (asterocentric UTC; all quoted uncertainties correspond to 3σ, except the density estimate below). We obtained the quadratic drift of the mean anomaly of 0.15 ± 0.14 deg yr−2. The orbital eccentricity is ≤0.03. We determined the ecliptic longitude and latitude of the radius vector of Dimorphos with respect to Didymos at the nominal time of the DART impact to Dimorphos (JD 2,459,849.46875 geocentric UTC) to be 222.°8 ± 7.°0 and −1.°6 ± 4.°2, respectively. We also estimated the bulk density of the system to be 2.37 ± 0.30 g cm−3 (1σ uncertainty).

Background: Burnout syndrome is found in health workers who are directly related to services and a high prevalence in care because they always experience stressful condition in workplace.  So, this condition needs attention from the hospitals. One of the effort to lower the burnout is self leadership and emotional intelligence mentoring.
Aim: This study aimed to analyzing the effect of self-leadership and emotional intelligence mentoring as an effort to lower the burnout rates of nurses
Methods: This study used a quantitative approach with a quasi-experimental method using a pretest-posttest with control group design. The population of this study was nurses at RSUD Noongan and RSU GMIM Bethesda Tomohon with a total of 344 nurses. Based on the sampling, a sample of 159 nurses was obtained. This study used the Maslach Burnout Inventory questionnaire on nurses to see the level of fatigue experienced before the intervention was given and The Revised Self-Leadership Questionnaire was adapted to measure nurses' self-leadership and a questionnaire to see the knowledge of research subjects (nurses) related to emotional intelligence. Data Analysis Methods used in this study was a structural equation modeling using partial least squares (PLS).
Results: The results shows that before the interventions, there was an effect of Self-Leadership on Burnout (0.000 <0.05) and there was an effect of Emotional Intelligence on Burnout (0.001 <0.05) at GMIM Bethesda Hospital. Also, after the interventions, there is an effect of Self-Leadership on Burnout (0.000 <0.05) and there is an effect of Emotional Intelligence on Burnout (0.001 <0.05) at GMIM Bethesda Hospital. Furthermore, before the interventions, there was an effect of Self-Leadership on Burnout (0.000 <0.05) and there is an effect of Emotional Intelligence on Burnout (0.000 <0.05).  Also, after the interventions, there is an effect of Self-Leadership on Burnout (0.000 <0.05) and there is an effect of Emotional Intelligence on Burnout (0.001 <0.05)
Conclusion: It can be seen that Self-Leadership and Emotional Intelligence have an effect on reducing the burnout levels of nurses at GMIM Bethesda Hospital and Noongan Hospital.

Tempeh is a traditional fermented soybean product widely consumed as part of the staple Indonesian diet. Besides its role as a protein source, the consumption of tempeh has been associated with health benefits, such as those from antioxidants. The fermentation of soybean by tempeh starter (Rhizopus oligosporus) determines the antioxidant capacities of tempeh. Updated studies reporting the fermentation conditions effect on tempeh are limited. Therefore, this research aimed to evaluate various fermentation conditions (lactic acid addition, fermentation time, fermentation temperature) on antioxidant capacities and physical characteristics of tempeh. In this study, soybean was soaked for 4 h, dehulled and boiled in water containing lactic acid with different concentrations (0.8%, 0.9% and 1.0%) for 30 mins. After cooling, the tempeh starter (106 CFU/g of Rhizopus oligosporus) was inoculated into the soybean. Afterward, the soybean was incubated at three different temperatures (25, 30 and 35 ℃) for 2, 3 and 4 days. For each fermentation condition, the physical characteristic (L*a*b* color value), antioxidant capacities and isoflavones contents of the tempeh powder were observed. The results showed that the tempeh fermented for more than 2 days was overripe, and higher incubation temperature could intensify the speed of fermentation, resulting in darker tempeh. A significant decrease in the L* value and increases in the a* and b* values were observed on tempeh stored at longer incubation time at various storage temperatures and various lactic acid concentrations (p < 0.05). Tempeh incubated at a higher temperature and longer incubation time exhibited lower EC­ 50 values of 2, 2'-Azino-Bis-3-Ethylbenzothiazoline-6-Sulfonic Acid (ABTS) scavenging and ferrous chelating ability, increase total phenolic contents and significantly increase aglycone isoflavones (p < 0.05). Therefore, the highest antioxidant capacity, the highest total phenolic content and the highest aglycone isoflavones were found in the tempeh incubated for 4 days at 35 ℃. The 1% lactic acid-tempeh had the highest antioxidant of chelating ability, highest total phenolic content and highest aglycone isoflavone increase.
