Wildfire-Induced Changes in Flood Risk in Recreational Canyoning Areas: Lessons from the 2017 Jerte Canyons Disaster
Authors: Ortega-Becerril José A. , Garrote Julio , Vicente Álvaro , Marqués María José
Published: August 2022

Few studies identify potential hazards affecting canyoning. This activity has an increasing number of practitioners, and hence, a greater number of people are affected by potential natural hazards. Mountain rivers are located in places subject to several hydrological hazards; the risks are mostly connected with floods produced by intense storms or dam operation, but changes in hydrological factors may alter the usual basin behavior given even moderate or less severe storms. Data about flood events and the peak discharge of the 2017 flood in the two studied canyons were collected by means of a quick field survey of water levels after the flood, hydrological modeling, and soil analysis. The present research shows the dramatic consequences of a two-year return period storm affecting a guided group of canyoneers. A previous wildfire changed the soil, leading to hydrophobic conditions and increasing the flood effects. Peak discharge increased from 2 m3 s−1 in normal conditions to 12 m3 s−1 under a hydrophobic regime related to wildfire occurrence; moreover, a reduction in the time of concentration also occurred, pointing to a more powerful and dangerous flood event. In this paper, some hydrological recommendations are highlighted that will be helpful in recreational canyoning management, leading to safer practice.

Published: August 2022

In order to evaluate the proportion of old and new water in drainage runoff, we recorded air temperature, drainage discharge, drainage runoff temperature, soil temperature, precipitation totals, and temperature. The results of separation by temperature were compared with the results of chemical separation using the stable isotopes δ 18O and δ 2H measured in causal precipitation and monitored in drainage runoff. Separation was determined based on precipitation temperature in 18 rainfall–runoff events and on soil temperature in 20 rainfall–runoff events, with no significant difference between results of separation of drainage runoff based on temperature and that based on isotopes. Separation of runoff based on temperature is feasible only for simple isolated rainfall–runoff events as opposed to those involving multiple rainfalls. Time to peak discharge was identified as a viable factor to determine whether to employ separation based on soil temperature or on precipitation temperature. Time to peak discharge showed a strong correlation with the intensity of precipitation. The results suggest that, conditional on analysis of a larger dataset, isotope separation of drainage runoff and, possibly, runoff in watercourses may potentially be replaced with more economical and technically simple measurement of soil and precipitation/air temperature.

Clarifying the response of wetland changes to climate change can improve the scientific conservation and utilization capabilities of wetland ecosystems, which is vital for their sustainable development. In this study, the spatial distribution and area changes of the different types of wetlands in the Yellow-River-Source National Park (YRSNP) were obtained using the object-based classification method for the years 2000, 2010, and 2020. The relationship between wetland change and climate factors was investigated by combining grey relation analysis and correlation analysis. The response of wetland change to different climatic factors was consequently clarified. The results showed that the river wetlands and lake wetlands increased significantly from the year 2000 to 2010 (4.04% and 4.21%, respectively). However, the total wetland area demonstrated a decreasing trend (7.08%), primarily due to the significant decrease in the marsh wetlands (6.81%). The total wetland area demonstrated a slightly increasing trend from the year 2010 to 2020 (0.14%), in which river wetlands and lake wetlands increased by 3.25% and 2.09%, respectively, while the marsh wetlands demonstrated a tendency to be stable. From the year 2000 to 2010, 75.53% of precipitation and 27.68% of temperature demonstrated a significant increase and an obvious warm–humid climate trend. However, from the year 2010 to 2020, the trend of increasing precipitation weakened, the temperature decreased slightly, and the warm–humid climate trend was not significant. From the year 2000 to 2020, the YRSNP river wetlands and lake wetlands were significantly and positively correlated with temperature and precipitation, while the marsh wetlands were most affected by climate warming, especially the warm-season temperatures. The spatial–temporal difference was not obvious in the correlation coefficient between marsh wetlands area change and the precipitation and temperature. The results of the study can provide a theoretical basis and technical support for the conservation of wetland ecosystems in the Three-River-Source National Park.

Authors: Tang Xiaodong , Huang Mutao
Published: August 2022

Lake eutrophication is a global water environmental problem and has become a research focus nowadays. Chlorophyll a concentration is an important index in terms of evaluating lake eutrophication. The aim of this study was to build an effective and universal empirical model for simulation of chlorophyll a concentration in Donghu Lake. On the basis of the relationship between chlorophyll a concentration and dissolved oxygen (DO), water temperature (T), total nitrogen (TN), and total phosphorus (TP), models for simulating chlorophyll a concentration were built by using simulated annealing (SA), genetic algorithm (GA), artificial bee colony (ABC), and particle swarm optimization (PSO) to optimize parameters of support vector machine (SVM). Moreover, a collaborative mode (Col-SVM model) was built by introducing data assimilation, and meanwhile, accuracy and universality of the model were studied. Modeling results showed that the application of optimization algorithms and data assimilation improved the performance of modeling based on SVM. Model simulation results demonstrated that the Col-SVM model has high accuracy, decent stability, and good simulation effect; the root mean square error (RMSE), mean absolute percentage error (MAPE), Nash–Sutcliffe efficiency coefficient (NSE), bias, and mean relative error (MRE) between simulated values and observed values were 10.07 μg/L, 0.31, 0.96, −0.050, and 0.15, respectively. In addition, model universality analysis results revealed that the Col-SVM model has good universality and can be used to simulate the chlorophyll a concentration of Donghu Lake at different times. Overall, we have built an effective and universal simulation model of chlorophyll a concentration that provides a new idea and method for chlorophyll a concentration modeling.

Authors: Surendra Kumar Jyothi Roopa , Pakka Vijayanarasimha Hindupur
Published: August 2022

The Arkavathi River, one of the major tributaries of the Cauvery River in southern India, is a major source of drinking water and agricultural irrigation to villages and townships in the region. Surface water quality distribution and characteristics of the Arkavathi Reservoir catchment and command area were evaluated using multivariate statistical analysis on 29 water quality parameters collected across 30 monitoring stations over a two-year, three-season period. Factor analysis (FA), agglomerative hierarchical clustering (AHC), analysis of variance (ANOVA) and t-tests were used to reveal strong links between parameters and to reveal significant variations in their concentration levels with respect to monsoon seasons and sampling locations across the sub-watersheds. Results from factor analysis showed strong groupings of specific parameters across seasons, while results from clustering revealed distinct clusters of sampling points around the river, upstream from the reservoir (where human activity is high), in the command area downstream from the reservoir (where irrigation activity is similar), in hilly regions towards the northeast of the study area and in the scrubland regions. Based on multivariate analysis findings, specific recommendations are made for water quality improvement in the reservoir catchment and command area.

Published: August 2022

The present research brings an input of information regarding the evolution of several physico-chemical parameters of two salt lakes (Lake Ocnei and Lake Rotund), part of the ”Salina Turda” resort, Cluj County, Romania, by means of on-site determinations. Measurements were carried out at six depths for each sampling point. We attempted to describe the behaviors of the two lakes under different natural conditions, in order to identify the impact of anthropogenic activities on the quality parameters of the two lakes. Our studies showed that the qualitative parameters of the water fluctuate as an effect of anthropogenic activities. A comparative analysis of the results gathered during three monitoring campaigns in 2016, 2018, and 2020 indicated that water quality was affected by anthropogenic activities such as mixing water layers which were characterized by different salinity values. The lakes tended to lose basicity, pH values varying between 9 at the surface level and 7 at −4 m. The thermal stratification phenomenon was only evident in the first year of monitoring; later on, the waters of both lakes appeared thermally homogenous down to the depth of −2 m. It was determined that the lakes had an uppermost freshwater layer, which disappeared during the bathing season because of vertical mixing. Interestingly, the two lakes showcased different behaviors at depths beyond −3 m. In addition, the infiltration of meteoric water that was polluted with nitrites and nitrates demonstrated the fact that anthropogenic activities that take place in the vicinity of the lakes generate negative effects on water quality. The presence of the heliothermal phenomenon was confirmed by the measurements made in the upper segment of the lakes. This layer of water consists of a mixture of fresh and salt water. The purpose of the research was to evaluate the water quality of the lakes, monitor its evolution during the bathing season and update the situation regarding the water quality of the two salt lakes by testing specific parameters.

Heilongjiang Province is located in the northeastern part of China and is the province with the highest latitude in China. As Heilongjiang Province is the most important grain production base in China, the Chinese government attaches great importance to the quality of the ecological environment in Heilongjiang Province, especially the analysis of changes in the quality of the water environment and their driving factors. We studied the changes in the environmental quality of surface water in Heilongjiang Province during the “13th Five-Year Plan” period (2016–2020), and analyzed the surface water for four major pollutants including the permanganate index, chemical oxygen demand, ammonia nitrogen and total phosphorus, and the change trends of the proportion of the water quality of class I–III and the proportion of the water quality of inferior class V. The results show that the environmental quality of surface water in Heilongjiang Province has improved significantly during the “13th Five-Year Plan”. The analysis of the driving factors of the change of surface water environment quality shows that the population, the primary industry, the tertiary industry and forestry are the main factors affecting the change of water environment quality in Heilongjiang Province.
Performance Assessment for Increasing Connection Rates of Private Water Supply Operators in Cambodia
Authors: Phea Sinat , Kazama Shinobu , Takizawa Satoshi
Published: August 2022

Private water supply operators (PWSOs) play an important role in extending piped water services in small cities in Cambodia. However, the connection rates to PWSOs are highly varied. Therefore, this study aimed to find the reasons for the low connection rates of PWSOs and to propose ways to increase the connection rates. The three PWSOs selected for this study supply water continuously, with sufficiently high pressure and good water quality except for the low concentration of residual chlorine, while the per capita supply volume varies significantly. Households with alternative water sources, namely rainwater and well water, consume less piped water than those without alternative water sources. Scattered service areas far away from water treatment plants had coverage rates that were lower than in compact service areas. The present connection costs and water tariffs are higher than those that non-connected households are willing to pay, though they pay high costs for bottled water. Due to the high variation in household income, connection fees and water tariffs are a financial burden for low-income households. Because the operating rates of the PWSOs are 21–47%, it is advised that PWSOs reduce their connection fees and water tariffs to obtain more connected households in their service areas.
Streamflow Measurement Using Mean Surface Velocity
Authors: Chen Yen-Chang , Hsu Yung-Chia , Zai Eben Oktavianus
Published: August 2022

This study developed an efficient discharge measurement method that can be applied to estimate the streamflow of natural streams and artificial channels. The conventional methods that apply current meters to measure discharge are costly, time-consuming, and labor-intensive. Owing to a shortage of observers in streamflow measurement and for the safety of hydrologists and with advances in measurement techniques, many have strongly suggested the use of non-contact methods when determining streamflow. The non-contact methods that use floats or surface velocity radar to determine the streamflow are becoming more and more popular especially during periods of high water. However, it is not easy to estimate the surface velocity coefficient of each vertical directly for determining the mean velocity in each subsection. As the relationship between the mean surface velocity and mean velocity of a stream cross-section is constant, an efficient and accurate non-contact method of streamflow measurement could be further developed. Thus, streamflow can be estimated by the constant, the mean surface velocity, and cross-sectional area of a stream. The mean velocity of a cross-section, used for parameter calibration, is usually obtained from the discharge made based on the velocity-area principle and cross-sectional area. The surface velocity was measured at the vertical that is then used to estimate mean velocity of a subsection. Once the parameter is determined, streamflow can be obtained from the surface velocity. This approach was further applied to a natural stream and an artificial channel. Measurements were made to verify the reliability and accuracy of the proposed approach. The results show that the relationship between mean channel velocity and mean surface velocity is very stable in both a natural stream and an artificial channel because the streamflow differences, given by the proposed and the conventional method, are relatively insignificant. As a result, mean surface velocity can be used to determine the streamflow quickly and provides for a reliable and accurate measurement of streamflow.

Developing countries are confronted with general issues of municipal wastewater management and treatment. Untreated wastewater and faecal sludge from septic tanks and traditional toilets are often discharged into rivers and used for urban agriculture without any treatment to minimize potential biorisks. Such practices result in potential environmental and public health risks. In this study, a wastewater treatment plant prototype coupled with Moringa oleifera seeds treatment was developed to evaluate their effectiveness for the reduction of faecal indicator bacteria and antibiotic-resistant bacteria in domestic wastewater. We demonstrated that that the proposed wastewater treatment plant prototype reduces bacteria by 99.34%. A high removal of the bacteria load was obtained after the addition of Moringa oleifera seeds into waters, with removal rates of 36.6–78.8% for E. coli, 28.3–84.6% for faecal coliform, 35.3–95.6% for Vibrio cholera and 32.1–92.4% for total flora. A similar effect of Moringa oleifera seeds was noted for the removal of antibiotic-resistant bacteria, extended-spectrum beta-lactamases and carbapenem-resistant Enterobacteriaceae, with a removal rate of up to 98% for E. coli and faecal coliform, 100% for Vibrio cholera and 91.96% for total flora. This study demonstrated the high removal efficiency pathogens and antibiotic-resistant bacteria from domestic wastewater using Moringa oleifera seeds.
A Dynamic Modeling Approach to Predict Water Inflow during Karst Tunnel Excavation
Authors: Bai Yang , Wu Zheng , Huang Tao , Peng Daoping
Published: August 2022

During tunnel construction in strongly developed karst terrain, water inrush hazards often occur due to the complex hydrogeological conditions, which require accurate prediction of water inflow. In this study, a dynamic modeling approach for water inflow prediction of karst tunnels using the conduit flow process (CFP) is developed that considers both karst duality and changing boundary conditions of the tunnel. The CFP model has a good agreement with field-observed hydraulic head after calibration, and the Nash–Sutcliffe model efficiency (NSE) for the CFP model is 97.3%. Numerical calculation of water inflow was conducted in a successive drilling scenario with permeability change of the surrounding rocks. Additionally, a modular three-dimensional finite-difference ground-water flow model (MODFLOW) has been applied to predict the water inflow, for comparison with the CFP model. The prediction results obtained from the CFP model are generally in close agreement with the field-observed results; the percentage errors were 13.3% and 5.4%, respectively. For the MODFLOW model, the percentage errors were 34.2% and 36.8%, respectively. The proposed CFP model is both closer to reality and more reasonable than the MODFLOW model in predictive analysis of water inflow into karst tunnels, reflecting the influence of karst conduits on the water inflow process.

Authors: Zavras Dimitris
Published: August 2022

The confinement measures implemented to limit the spread of SARS-CoV-2 disrupted daily life and increased the risk of poor mental and physical health. The COVID-19 pandemic also resulted in unprecedented disruptions to healthcare access due to both supply and demand factors, creating barriers to disease management. Thus, the objective of this study was to investigate the factors that influenced views on coping with confinement measures. For this study, we used data from the Eurobarometer 93.1. The sample consisted of 1016 individuals aged 15 years and over. The sample design was multi-staged and random (probability). For the purpose of the study, a multinomial logistic regression model was fitted and used views on the experience of coping with confinement measures as the outcome variable. Several demographic, health-related, and economic factors were used as independent variables. According to the results, residents of more densely populated areas, females, and individuals who consider their personal health an important issue had more negative views of their experience during confinement measures. This was also true for individuals from financially worse-off households. The study results indicate a direct influence of economic and health-related factors on the experience of coping with the implemented confinement measures.

Objectives: The prevalence of fatigue in patients receiving hemodialysis is high. This study aimed to investigate the effect of Rosa damascena oil on fatigue severity in patients receiving hemodialysis. Materials and Methods: This randomized controlled trial was performed on 74 patients receiving hemodialysis in Tabriz, Iran from January 21 to February 21, 2019. The patients were conveniently recruited and assigned into two groups of intervention and control using a block randomization method with block sizes of four and six and a sequence of 1:1. Patients in the intervention group were trained to inhale three drops of R. damascena oil each night for one month. We used the Fatigue Severity Scale (FSS) for data collection and analyzed the data using the independent samples and paired t tests. Results: No significant difference was found between the two groups respecting the mean baseline fatigue scores (P=0.12). However, at the end of the study, the mean fatigue score was significantly lower in the intervention group compared to the control group (P=0.001). Conclusions: We witnessed that R. damascena oil aromatherapy significantly reduced the severity of fatigue in patients receiving hemodialysis. This useful and inexpensive technique can be utilized as a complementary method to relieve fatigue in patients receiving hemodialysis.

Published: August 2022

Background. The purpose of the present study was to investigate the relationship between perceived organizational support and job crafting considering the moderating role of job embeddedness of nurses in this relationship. The three main dimensions considered for job crafting concept were: task crafting, relational crafting and cognitive crafting. Methods. This research is an applied one in terms of purpose, and a descriptive survey research in terms of data gathering method. The statistical population of this study was the nurses of hospitals affiliated to Qom University of Medical Sciences. The sample consisted of 269 nurses and the sampling method was random. The standard questionnaires of Slemp &Vella-Brodrick (2013), Eisenberger et al., (1986) and Felps et al., (2009) were used for data collection on three main variables of the study i.e., job crafting, perceived organizational support and job embeddedness. The data were analyzed by structural equation modeling using Smart PLS3.2.6 software. Results. The findings showed that perceived organizational support had a significant positive effect on the relational (0/651 path coefficient) and cognitive (0/681 path coefficient) dimensions of job crafting. But this relationship for task crafting was not confirmed (0.836 T Value). In addition, job embeddedness had a significant moderating role in the relationship between perceived organizational support and all aspects of job crafting (0/461, 0.472 and 0.642 path coefficients). That is to say, employees with job embeddedness, upon perceiving organizational support, were more likely to do job crafting in all three task, relational and cognitive dimensions. Conclusion. Since the results showed that perceived organizational support affects job crafting in relational and cognitive dimensions, we suggest managers of Qom University of Medical Sciences pay due attention to perceived organizational support in the complexity of today's jobs and the need to consider the role of employees in designing their jobs

Our forefathers gave our mother Tamil as Muthamil. Among them, the prose flourished and became influential in both the prose and poetry. The effects of the changes brought about by the dominance of the highlanders were also seen in the literature. Prose arose from the syllabic form, just as new poetry arose from traditional poetry. This prose is based on the method of revealing the material as it is without concealing it. After the development of prose, fields like religion, history, medicine were written in prose. Thus the poet Mitra is a modern literary creator. His prose works are based on research skills. He did not limit his knowledge with literature and broadened his knowledge in the world of research and prose. The purpose of this article is to examine the prose skills of the poet Mitra whose real name is V. Unnamalai.

Transfer of Analogies in Traditional Programming Languages to Teaching VHDL
Authors: Öztekin Halit , Gülbağ Ali
Published: August 2022

One of the languages available to describe a digital system in FPGA is the VHDL language. Since programming in hardware requires a different way of thinking than developing software, the students face some difficulties when trying to design in VHDL language with the previous and long experiences kept in mind in the learning of software imperative programming. These are its concurrency, parallel and sequential model. Due to the insufficient understanding of these topics, it is difficult for students to master the VHDL language. Analogies change the conceptual system of existing knowledge by linking the known to the unknown and by changing and strengthening their relationships. This study contributes to overcoming the problems that students encounter in the coding of the above-mentioned topics in VHDL language by using their experiences in traditional programming languages through analogies. Analogies were used in an undergraduate embedded systems course to explain complex concepts such as those related to signals, concurrent/parallel process; and to encourage comprehensive projects in digital circuit design. In feedback from students, the discussion and negotiation of analogies seems to minimize confusion and from using inappropriate expressions in using VHDL language.

Published: August 2022

Abstract
Background: In this study, we aimed to investigate the outcomes of the first coitus injuries in newly married couples, which are common in our society.

Material and Methods: This is a retrospective study involving 89 patients admitted to the obstetrics and gynecology clinic of our hospital with the complaint of bleeding secondary to postcoital vaginal discharge between January 2017 and December 2020.

Results: The mean age of 89 patients admitted due to postcoital genital injury was 26 ± 8 years. All 89 of the patients had genital injury in the first coitus. The mean number of lesions was 1.4 ± 0.73 and their dimensions were 2.7 ± 0.96 cm. 65% of the patients were in primary and lower education groups.
The main localizations of genital injuries were 29 in the vaginal introitus, 13 in the right lateral, 10 in the left lateral, and 10 in the posterior fourchette. Preoperative mean hemoglobin level was 11.2 ± 1.78 and postoperative hemoglobin level was 9.8 ± 1.3. The mean operation time was 21.2 ± 7 minutes and the hospital stay was 1.04 ±0.2 days. 19 of the interventions were repaired under local anesthesia under office conditions and 70 were repaired under spinal anesthesia or sedoanalgesia in the operating room.

Conclusions: Vaginal injuries after coitus are considerably high. After these injuries, there is rapidly developing and life-threatening bleeding. Premarital couples receiving psychosexual education, preventing pregnancies at an early age, and conducting socio cultural-based studies may help to reduce genital injuries after the first coitus.

Stakeholders’ concern about the dwindling quality of teachers’ instructional tasks and students’ academic performance in Nigeria secondary schools could be attributed to the perceive inadequacies in instructional planning. This study therefore investigated teachers’ instructional planning and productivity in public secondary schools in Ondo North Senatorial District of Ondo State, Nigeria. Descriptive survey research design was adopted, and 600 teachers and 30 principals were sampled using multi-stage and simple randomly sampling techniques. Data were collected using Instructional Planning Questionnaire (IPQ), and Teachers’ Productivity Questionnaire (TPQ). Three research questions and two hypotheses guided the study. The research questions were answered using descriptive statistics while the hypotheses were tested at 0.05 level of significance using Pearson Product Moment Correlation (PPMC). Results indicated a moderate level of teachers’ instructional planning (Mean = 2.97); teachers demonstrated high performance in the preparation of lesson notes, content knowledge, classroom management and record-keeping while the least performed tasks included the use of instructional materials, learners’ assessment, performance feedback and review of academic activities. Teachers’ instructional planning has significant relationship with instructional task performance [r = 0.896 p<0.05], and students’ academic performance [r = 0.851 p<0.05]. The study concluded that teachers performed instructional planning at a moderate level while concerted efforts are needed to boost productivity. It was recommended that the State Ministry of Education and relevant professional bodies should organize capacity training seminars/workshops to improve teachers’ instructional tasks performance in secondary schools.

University core courses are basic courses set by the university which are also certified by the Ministry of Higher Education (MOHE). This course is also subject as a course prescribed by the university senate to ensure that a comprehensive education can be given to a student. Students must take and must pass this course at the same time will qualify students to graduate according to the time set. At Universiti Teknologi Mara (UiTM), one of the university's core courses of Ethics and Civilization which is a compulsory course under the auspices of the Academy of Contemporary Islamic Studies (ACIS) and offered to students at the diploma and bachelor's degree levels at each branch campus entire Malaysia. However, it is questionable whether this course is effective in fostering racial unity among UiTM students because as far as we know, all university students consist of Bumiputera students only. In line with that, the objective of this study is to identify the level of student acceptance of the course content and will then analyze how the effectiveness of this course in shaping racial unity among UiTM students. The measurement tools used in data collection include questionnaires distributed online using google form software to 455 UiTM students in Malaysia at random. The data obtained from this random sample were then analyzed using descriptive analysis through quantitative software to see the overall continuity of the analysis of the study findings. The results obtained will then draw conclusions on the characteristics of the studied population. The results of the study found that the university's core courses are dynamic and flexible, as well as in line with current needs and requirements in an effort to fulfill the components of Malaysian nationhood as well as have their own role in fostering racial unity in particular.

The SPPIV evaluation system is an innovation project that has been implemented to facilitate the monitoring process and the preparation of evaluation scores for the Innovation and Invention Competition Through Exhibition (iCompEx'2020). This qualitative study was conducted to evaluate the effectiveness using computer based system to replace the manual system that has been used in icompex’19. Therefore, the SSPIV system is developed using Microsoft Access 365 which allows system users namely the Scoring System Committee (JSP) and the Assessing Panel Committee (JPP). Then, its should make considering three things, to identify the effectiveness of the SPPIV system, performance of JPP evaluation activities and minimize time and cost management. The findings of this study found that the use of SPPIV system is is the best way of improving the innovation project. According to Boer's, this activity helps technological innovation to produce products and material services that will meet the needs of consumers (Boer,2002). Similarly Mohd Azizol also viewed that a new technology that was introduced in an organization, a study should be conducted to find out what are the benefits obtained by the organization.

Kegiatan pembelajaran kimia untuk siswa SMA agar lebih menarik dapat dilakukan dengan inovasi media pembelajaran. Media pembelajaran yang sesuai untuk bisa diterapkan pada saat ini adalah media berbasis blended learning. Pembentukan karakter yang perlu dikem-bangkan dalam model pembelajaran blended learning salah satunya adalah karakter religius. Karakter religius pada pelajaran kimia dapat dikaitkan dengan ayat yang ada pada Al-Qur'an salah satunya adalah materi laju reaksi. Tujuan penelitian ini adalah untuk mengetahui keefektifan modul, respon siswa, dan kelayakan modul bagi siswa kelas XI pada materi laju reaksi. Metode penelitian ini menggunakan R&D (Research and Development) Borg & Gall. Hasil penelitian menunjukkan bahwa uji validasi modul laju reaksi terintegrasi karakter religius menunjukkan nilai yang sangat tinggi dengan rata-rata skor materi 87,6% dan media 89%. Pada uji coba skala kecil hasil respon tanggapan siswa terhadap modul terintegrasi dengan karakter religius dikategorikan sangat layak. Berdasarkan hasil pembahasan, dapat disimpulkan bahwa modul laju reaksi berkarakter religius dapat digunakan sebagai media alternatif bagi siswa kelas XI.
Chemistry learning activities for high school students to make it more attractive can be done with learning media innovations. The appropriate learning media to be applied at this time is blended learning-based media. One of the characteristics that need to be developed in the blended learning model is religious character. The religious character in chemistry lessons can be related to the verses in the Qur'an, one of which is the material on the rate of reaction. The purpose of this study was to determine the effectiveness of the module, student responses, and the feasibility of the module for class XI students on the reaction rate material. This research method uses R&D ( Research and Development) Borg & Gall. The results showed that the validation test of the integrated reaction rate module of religious characters showed a very high value with an average material score of 87.6% and media of 89%. In the small-scale trial, the results of student responses to the integrated module with religious character were categorized as very feasible. Based on the results of the discussion, it can be concluded that the reaction rate module with religious characteristics can be used as an alternative medium for class XI students.

The atmospheric pressure non-thermal plasma generated by low-frequency (LF)-microwave hybrid discharge has been employed to investigate the effects of plasma treatment on the germination and growth of radish (Raphanus sativus L.) sprout seeds. The plasma generated with admixture discharge gas of Ar-O2 was adopted for the irradiation of seeds. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analyses were performed to elucidate the physical and chemical state changes of seed surfaces after plasma treatment. The reactive species produced in the plasma were investigated using optical emission spectroscopy (OES) and chemical indicator (CI). The results demonstrate that higher reactive oxygen species were generated from the LF-microwave hybrid plasma compared to conventional LF plasma jet. Moreover, the higher germination percentage and shorter germination time were obtained with the LF-microwave hybrid plasma compared to LF plasma jet and control group. It is considered that reactive species produced in the LF-microwave hybrid plasma are related to the germination time of the radish sprout seed.
