Authors: Sari Sri Padma
Published: March 2021

Rehabilitation for people with mental disorders (PMD) plays an important role in helping the healing process. Given the limited number of mental institutions, Islamic boarding schools participate in assisting in the handling of PMD. This study aims to: (i) Identify the religious activities conducted by Islamic boarding schools in the rehabilitation of PMD, (ii) Identify the benefits of spiritual therapy and religious activities in assisting the recovery of PMD. This is a mixed-method research conducted in three boarding schools that provide rehabilitation of the PMD in Yogyakarta, namely Nurul Haromain, Al Islamy and Tetirah Dzikir in February-March 2017. Data from 84 randomly selected respondents with mental disorders were collected using Daily Spiritual Experience Scale (DSES) and PSP (Personal and Social Performance) questionnaires to see the relationship between the spiritual level with changes in personal and social functions in PMD and analyzed using spearman rank correlation test. Qualitative data is conducted by Focus Group Discussion. Results show that there was a relationship between the spiritual level and changes in the personal and social functions of the PMD (p = 0.008; r = 0.286). In addition, most of the religious activities obtained by PMD were praying, reciting the Quran and dhikr.  The perceived benefits of religious activities for the PMD were feeling healed from mental illness and the heart becomes more calm. Spiritual therapy in the form of religious activities has an important role for PMD in assisting healing and providing hopes. Activities and living in Islamic boarding schools may enhance PMD’s confidence and social function.

Published: March 2021

The prevalence of people suffering from depression in Indonesia is 21,8 percent. The percentage shows that there is a 12,1 percent higher prevalence compared to the global prevalence. Depression can affect anyone, including the freshman year students who are undergoing a transition of the development phase from secondary education to college education as late teenagers. The transition causes conflicts and adjustments as there is a culture shock that may trigger the depression. Depression is a mental disorder marked by the appearance of symptoms such as the loss of interest, feelings of guilt, mood loss, sleep disorder, and eating disorders. Thus, this research aims at figuring out the picture of depression levels based on residency among freshman year students in Sobo campus PSDKU Universitas Airlangga in Banyuwangi. This research is descriptive quantitative research using a cross-sectional study conducted on May 16, 2019, to May 20, 2019, with a total population of 83 students. The data mining technique used in this research is done by spreading the questionnaire of The Zung Self Depression Scale. The previously processed data through cleaning, coding, and tabulation stages are presented in table and description. The result showed Freshman year students who live by themselves or in boarding houses are included in the category of normal depression level with the most number of 60 people (72,29%). Meanwhile, freshmen year students who live with other people are included in the same category with less number of 8 people (9,64%). The conclusion of this reseach, depression level experienced by freshman year students of Sobo campus PSDKU Universitas Airlangga in Banyuwangi tends to be in the category of normal depression, which can be handled well to prevent the change from normal depression to mild or severe depression. The students can practice their adaptation skills and do coping according to their self-states, for instance doing physical activities.

ABSTRACT

Introduction: Poison (visha) are of plant, animal and mineral origin which produce deleterious effect to the body. Agada Tantra is the branch of Ayurveda. There is requirement of antidotes and antitoxic drugs to arrest the effect of visha. There are such drugs called vishaghna (antipoisonous/ anti-toxic) mentioned in ayurveda samhitas and textbooks. Materials and Methods: major Ayurveda samhitas viz. Charak samhita, Sushruta samhita, Astang Hridyum were looked into for references regarding vishaghna drugs. Observation and results: there are huge number of plants, animal products and minerals mentioned under various categories and groups. These drugs with similar properties and actions are grouped together, e.g. Vishaghnagana in Charak samhita, aragvadhadigana, patoladigana, anjanadigana, trapuadigana etc in Sushruta samhita. Similarly Astanga hridyum also contains similar groups. Conclusion: There is abundancy of poison in environment in various forms manifested as pollution, epidemics etc. we have such huge resources of anti-toxic drugs naturally occurring that can be utilized to address the biggest issues of the planet today. These drugs needs to be considered for experimental studies.

SCIENTIFIC AND METHODOLOGICAL SUPPORT OF SCHOOL EDUCATION IN HISTORY IN UKRAINE (THE END OF XX – THE BEGINNING OF XXI CENTURY): HISTORIOGRAPHY OF EDUCATIONAL EDITIONS
Authors: Antybura Yuliia
Published: March 2021

The article considers the historiography of the problem of scientific and methodological support of school education in history in Ukraine. The results of the analysis of the complex of studies and scholarly publications review on the topic are presented in this paper. The general scientific research methods are defined: they are analysis, synthesis, systematization, analogy, classification, which were used to analyze the views of domestic and foreign scientists on the problems of school history education, its scientific and methodological support, updating the content and approaches to teaching history at school. The author defines the concept “scientific and methodological support” through such components as curricula, teaching aids and textbooks, methodology of teaching a subject, legislative and regulatory framework. It is noted that the problems of scientific and methodological support of school historical science were studied by both academic historians and teachers-practitioners. Nowadays, the studies devoted to the content and methods of teaching history are becoming increasingly important. Scientific papers on the topic are divided into several groups. The first group includes general pedagogical research concerning the goals and objectives of secondary education in Ukraine. Such works include teaching aids and textbooks on general pedagogy, history of pedagogy, pedagogical anthologies. The second group includes serious monographs describing the content of history education, updating programs and textbooks. The particular emphasis is placed on works covering the period from Ukraine’s independence, at the beginning of the XXI century. The third group consists of works on the methodology of teaching history in schools. Such works are focused on the practical aspects of teaching history, the structure and content of history lessons, and the like. The fourth group of scientific research consists of those papers, which are devoted to the discussions about the purpose and content of historical education. These are materials of thematic conferences and round tables. The author determined the prospects for further scientific research. Based on the analysis and synthesis of the available scientific papers, it is possible not only to give a detailed description of school history courses, textbooks, approaches to teaching history at school, but also to identify the positive and negative aspects of the content of school history education in Ukraine, to identify problems and ways to overcome them.
APPLICATION OF DIGITAL INFORMATION RESOURCES IN DISTANCE LEARNING
Authors: Hevko Ihor
Published: March 2021

The article shows that the introduction of distance learning courses, trainings, webinars, workshops, round tables, etc. at a more systematic level are the effective ways of forming digital literacy. Possibilities of using distance learning in higher education institutions are considered. The article emphasizes that digitization affects not only the content of education but also its organization. These processes have mixed implications for positioning of universities and teaching work. Digitalization of education opens up new perspectives for any professional field, as it enables to expand the context of activities, organize international cooperation, create virtual groups and communities, forums and chats, provide access to materials of various formats (texts, multimedia, television, etc.), expand communication with native speakers through various Internet systems, etc. The advent of distance education has led to a whole new understanding of the learning process and has expanded its capabilities.
The introduction of distance learning in Ukraine is currently in its active stage. At the beginning of the XXI century The Concept of Development of Distance Education in Ukraine and the Regulation on Distance Learning were approved. Today, the role and importance of digital educational resources and technologies in the educational sector is increasing; a great deal of efforts are being made to harmonize the structure of national HEIs with European requirements and to improve the quality of distance learning, which should lead to an increase in the level of training of specialists. Distance education is an important component of modern specialist training in many countries of the world, based on the use of both the best traditional teaching methods and new DER, as well as on the principles of self-study, intended for the general public irrespective of material security, place of residence, health status. A distinctive feature of distance education is interactive learning. Students have the opportunity not to attend classes, but to study at convenient time and in a convenient place. The main goal of distance learning is to ensure further development of the education system towards providing it with features and characteristics of open education (accessibility, mass, personal orientation, real continuityetc).
Thus, distance education is a 21st century specialist training system, characterized by high professionalism that strives for collaboration, self-affirmation and a high level of communication with colleagues. It is characterized by a great intensification of socially significant motives: business, cognitive, cooperation, self-realization and development, self-affirmation and communication through the use of open and computer-based learning and modern means of communication.
DEVELOPMENT PECULIARITIES OF DOMESTIC THEORY AND PRACTICE OF USING THEATER ART IN EDUCATIONAL WORK WITH CHILDREN IN THE FIRST THIRD OF THE XX CENTURY
Authors: Dergach Marharita
Published: March 2021

The article presents the results of the analysis of historical materials on the use of theatrical art as a means of education, training and socialization of children by teachers and theatrical practitioners of Ukraine in the early twentieth century. The in-depth analysis of archival sources, manuscripts, and old printed works allowed to distinguish teachers whose achievements allow us to understand the peculiarities of the formation of the theoretical foundations and practice of introducing theatrical art into the educational system of Ukraine.
During this historical period, the following issues were raised: the age limits of children's involvement in theatrical creativity, the specifics of the audience; mechanisms of children's dramatic creativity and development of appropriate approaches to the organization of theatrical work with children; requirements for repertoire selection; stages of acquainting children with theatrical art, methods of organizing and conducting rehearsal work, etc.
Scholars and educators of the time noted that children and adolescents who played only for their peers and parents could be involved in theatrical work; acquaintance with theatrical art should begin with simple theatrical forms, dramatized games, acting out charades, proverbs, "living pictures" and gradually move on to staging dramatic works; the basis of children's theatrical play are emotional experiences, and therefore the task of the leader is to emotionally captivate the child, put him/her in the right emotional state.
Based on the analysis of culturological aspects of the functioning of theatrical art in society, theoretical approaches to understanding the pedagogical possibilities of theater and the practice of using theatrical art in school, it was determined that pedagogical materials of the early twentieth century emphasized the importance of theater for the development of human aesthetics, moral and ethical qualities of the personality, activation of his/her creative forces, psychological and psychophysical characteristics of a child: imagination, memory; self-awareness, emotions, feelings, empathy, communication skills and abilities. Possibilities of theatrical art in fostering children’s mastering a native language, in the training of attentive and competent spectators were defined.

Fueling Agricultural Growth In Madhya Pradesh Through Formal Credit- A
Way Towards Financial Inclusion
Authors: Rathi Meenakshi , Sharma Prof. Dr.Vivek
Published: March 2021

Financial inclusion is emerging as new paradigm of economic growth. In India 68.84% (census 2011) population lives in rural area out of which 25.70% people are poor and rural finance is a matter of credit concern in the economy. Madhya Pradesh has reported the best productivity growth in terms of Agriculture over past few years, and has improved its infrastructure. This kind of change in one sector – agriculture – is initiating growth in the entire economy of the state. Agriculture in Madhya Pradesh (MP) grew at 9.7 per cent per annum during the decade (2008-18). The last five years have been spectacular when agricultural growth rate stood at 18% per cent per annum. The study intend to examine the influence of access to credit on agricultural productivity in Madhya Pradesh, It is based on the secondary data compiled from several sources, has revealed that the formal credit to agriculture in real terms has increased during the
past decade. The nature and availability of panel dataset constrained the study to examine the pooled data analysis for arriving at results. The analysis was carried out with the data of selected districts of Madhya Pradesh over the period 2008-2018. The findings of the study shows the evidence of long run relationship between agriculture production and agricultural credits provided to small and marginal farmers. The results revealed that total credit to agriculture has a positive and significant impact on the level of agriculture production in the region. The Study also examines nature of the relationship between formal agricultural credit and productivity of crops which ultimately led to an improvement in state GDP. One of the major findings was related to inadequacy of credit to small and marginal farmers. Therefore more innovative models are required to be formulated using Econometric Financial Models for making the credit availability and accessibility more convenient. Thus it can be concluded that formal agriculture credit is required for the inclusive growth of the economy of the state.

Este artigo é parte integrante da Dissertação de Mestrado em Direção Estratégica do pesquisador, pela Universidad Internacional Iberoamericana – UNINI PORTO RICO. No entanto, estudar o campo da gestão de talentos, em especial, o recrutamento e a seleção de pessoal pelo vértice da gestão por competências e por habilidades é de fato uma questão desafiadora para aqueles que usam o termo competências de gestão. Embora, a competência e nem a habilidade estejam no rol profissional dos recursos humanos da instituição podemos avaliar e rever que o caminho de um processo de realização de seleção e gestão de talentos nos parecem caminhar por outras dimensões; ou seja, selecionar e recrutar por habilidades e por competências não são traços básicos, únicos e evidentes em síntese. Por isso, o cenário da gestão de talentos, especificamente, o recrutamento e seleção de pessoal deságuam em uma análise na qual as práticas de gestão por competências e por habilidades são visto por muitos profissionais da área como apenas um custo e vem à tona a crítica pela ótica de que qualquer pessoa pode recrutar, selecionar e manter os recursos humanos na instituição. Por isso, existem pontos de convergência e divergência em relação à prática de recrutar, selecionar, reter e manter os recursos humanos na instituição de Ensino Superior.
Modelling the influence of biotic plant stress on atmospheric aerosol
particle processes throughout a growing season
Authors: Taipale Ditte , Kerminen Veli-Matti , Ehn Mikael , Kulmala Markku , Niinemets Ülo
Published: March 2021

Abstract. Most trees emit volatile organic compounds (VOCs) continuously throughout their life, but the rate of emission, and spectrum of emitted VOCs, become substantially altered when the trees experience stress. Still, models to predict the emissions of VOCs do not account for perturbations caused by biotic plant stress. Considering that such stresses have generally been forecast to increase in both frequency and severity in future climate, the neglect of plant stress-induced emissions in models might be one of the key obstacles for realistic climate change predictions, since changes in VOC concentrations are known to greatly influence atmospheric aerosol processes. Thus, we constructed a model to study the impact of biotic plant stresses on new particle formation and growth throughout a full growing season. We simulated the influence on aerosol processes caused by herbivory by European gypsy moth (Lymantria dispar) and autumnal moth (Epirrita autumnata) feeding on pedunculate oak (Quercus robur) and mountain birch (Betula pubescens var. pumila), respectively, and also fungal infections of pedunculate oak and balsam poplar (Populus balsamifera var. suaveolens) by oak powdery mildew (Erysiphe alphitoides) and poplar rust (Melampsora larici-populina), respectively. Our modelling results indicate that all the investigated plant stresses are capable of substantially perturbing both the number and size of aerosol particles in atmospherically relevant conditions, with increases in the amount of newly formed particles by up to about one order of magnitude and additional daily growth of up to almost 50 nm. We also showed that it can be more important to account for biotic plant stresses in models than significant variations in e.g. leaf area index, and temperature and light conditions, which are currently the main parameters controlling predictions of VOC emissions. Our study, thus, demonstrates that biotic plant stress can be highly atmospherically relevant and it supports biotic plant stress emissions to be integrated into numerical models for prediction of atmospheric chemistry and physics, including climate change projection models.
Technical note: sea salt interference with black carbon quantification
in snow samples using the single particle soot photometer
Authors: Zanatta Marco , Herber Andreas , Jurányi Zsófia , Eppers Oliver , Schneider Johannes , Schwarz Joshua P.
Published: March 2021

Abstract. After deposition from the atmosphere, black carbon aerosol (BC) takes part in the snow albedo feedback contributing to modification of the Arctic radiative budget. With the initial goal of quantifying the concentration of BC in the Arctic snow and subsequent climatic impacts, snow samples were collected during the Polarstern expedition PASCAL (Polarstern cruise 106) in the sea ice covered Fram Strait in early summer 2017. The content of refractory BC (rBC) was then quantified in the laboratory of the Alfred Wegener Institute with the single particles soot photometer (SP2). We found strong correlations between both rBC mass concentration and rBC diameter with snow salinity. Therefore, we formulated the hypothesis of a salt-induced matrix effect interfering with the SP2 analysis. By replicating realistic salinity conditions, laboratory experiments indicated a dramatic six-fold reduction in observed rBC concentration with increasing salinity. In the salinity conditions tested in the present work (salt concentration below 0.4 g l−1) the impact of salt on nebulization of water droplets might be negligible. However, the SP2 mass detection efficiency systematically decreased with salinity, with the smaller rBC particles being preferentially undetected. The high concentration of suspended salt particles and the formation of thick salt coating on rBC cores might have caused problems to the SP2 analog-to-digital conversion of the signal and incandescence quenching, respectively. Changes to signal acquisition parameters and laser power of the SP2 improved the mass detection efficiency, which, nonetheless, never attained unity values. The present work provides the evidence that high concentration of sea salt undermines the quantification of rBC in snow performed with the SP2. This interference was never reported and might affect future analysis of rBC particles in snow collected, especially, over sea ice or coastal regions strongly affected by sea salt deposition.
Measurement report: PM2.5-bound nitrated aromatic compounds in Xi'an, Northwest China – seasonal variations and contributions to optical properties of brown carbon

Published: March 2021

Abstract. Nitrated aromatic compounds (NACs) are a group of key chromophores for brown
carbon (light-absorbing organic carbon, i.e., BrC) aerosol, which affects
radiative forcing. The chemical composition and sources of NACs and their
contributions to BrC absorption, however, are still not well understood. In
this study, PM2.5-bound NACs in Xi'an, Northwest China, were
investigated for 112 daily PM2.5 filter samples from 2015 to 2016. Both
the total concentrations and contributions from individual species of NACs
show distinct seasonal variations. The seasonally averaged concentrations of
NACs are 2.1 (spring), 1.1 (summer), 12.9 (fall), and 56 ng m−3
(winter). Thereinto, 4-nitrophenol is the major NAC component in spring
(58 %). The concentrations of 5-nitrosalicylic acid and 4-nitrophenol
dominate in summer (70 %), and the concentrations of 4-nitrocatechol and
4-nitrophenol dominate in fall (58 %) and winter (55 %). The NAC species
show different seasonal patterns in concentrations, indicating differences
in emissions and formation pathways. Source apportionment results using
positive matrix factorization (PMF) further show large seasonal differences
in the sources of NACs. Specifically, in summer, NACs were highly influenced
by secondary formation and vehicle emissions (∼ 80 %), while
in winter, biomass burning and coal combustion contributed the most
(∼ 75 %). Furthermore, the light absorption contributions of
NACs to BrC are wavelength-dependent and vary greatly by season, with maximum contributions at ∼ 330 nm in winter and fall and
∼ 320 nm in summer and spring. The differences in the
contribution to light absorption are associated with the higher mass
fractions of 4-nitrocatechol (λmax⁡= 345 nm) and 4-nitrophenol
(λmax⁡= 310 nm) in fall and winter, 4-nitrophenol in spring,
and 5-nitrosalicylic acid (λmax⁡= 315 nm) and 4-nitrophenol in
summer. The mean contributions of NACs to BrC light absorption at a
wavelength of 365 nm in different seasons are 0.14 % (spring), 0.09 %
(summer), 0.36 % (fall), and 0.91 % (winter), which are about 6–9 times
higher than their mass fractional contributions of carbon in total organic
carbon. Our results indicate that the composition and sources of NACs have
profound impacts on the BrC light absorption.

Abstract. Magnetosheath jets are regions of high dynamic pressure, which can traverse
from the bow shock towards the magnetopause. Recent modelling efforts, limited
to a single jet and a single set of upstream conditions, have provided the
first estimations about how the jet parameters behave as a function of
position within the magnetosheath. Here we expand the earlier results by
doing the first statistical investigation of the jet dimensions and
parameters as a function of their lifetime within the magnetosheath. To verify
the simulation behaviour, we first identify jets from Magnetosphere
Multiscale (MMS) spacecraft data (6142 in total) and confirm the Vlasiator
jet general behaviour using statistics of 924 simulated individual jets. We
find that the jets in the simulation are in quantitative agreement with the
observations, confirming earlier findings related to jets using Vlasiator. The
jet density, dynamic pressure, and magnetic field intensity show a sharp jump
at the bow shock, which decreases towards the magnetopause. The jets appear
compressive and cooler than the magnetosheath at the bow shock, while during
their propagation towards the magnetopause they thermalise. Further, the shape
of the jets flatten as they progress through the magnetosheath. They are able
to maintain their flow velocity and direction within the magnetosheath flow,
and they end up preferentially to the side of the magnetosheath behind the
quasi-parallel shock. Finally, we find that Vlasiator jets during low solar
wind Alfvén Mach number MA are shorter in duration, smaller in their extent, and
weaker in terms of dynamic pressure and magnetic field intensity as compared
to the jets during high MA.
Benchmarking Data-Driven Rainfall-Runoff Models in Great
Britain: A comparison of LSTM-based models with four lumped
conceptual models

Published: March 2021

Abstract. Long short-term memory models (LSTMs) are recurrent neural networks from the emerging field of Deep Learning (DL), which have shown recent promise when predicting time-series especially when data are abundant. Rainfall-runoff modelling presents a challenge, yet accurate hydrological models are vital for flood forecasting, hazard impact assessment, and to assess the potential effects of climate change on floods and water resources. In this study, we compare the performance of two DL-based models, a LSTM and an Entity Aware LSTM (EA LSTM). The DL models were trained using a newly published data set, CAMELS-GB, for a sample of 518 catchments across Great Britain. To identify spatial and seasonal patterns in model performance, we compare the DL models against benchmark outputs from four lumped conceptual models recently configured for rainfall-runoff modelling in Great Britain. Our findings show that the LSTM models simulate discharge with consistently high model performance scores, including in catchments typically considered difficult to model. The LSTM achieves a mean catchment NSE of 0.88 (0.86 for the EALSTM), which represents a performance improvement of 10 %–16 % compared with the benchmark conceptual models. Seasonal and spatial patterns indicate that the largest performance improvement relative to the benchmark is in the drier summer months and in drier catchments in the South East of England. By comparing LSTMs with conceptual models, we diagnose possible reasons for their different performance. We suggest that LSTMs offer useful predictive capability for rainfall-runoff modelling in Great Britain and elsewhere and note their value to support process understanding in locations where processes are less well understood.
On the Contribution of Grain Boundary Sliding to Firn
Densification – an Assessment using an Optimisation Approach
Authors: Schultz Timm , Müller Ralf , Gross Dietmar , Humbert Angelika

Abstract. Physics based simulation approaches to firn densification often rely on the assumption that grain boundary sliding,first introduced by Alley (1987) to firn, is the leading process driving the first stage of densification. However, often so calledsemi empirical models are favored against the description of grain boundary sliding due to simplicity and uncertainties regard-ing model parameters. In this study, we are assessing the applicability of grain boundary sliding to firn using a numeric firn5densification model and an optimisation approach, for which we formulate variants of the constitutive relation by Alley (1987).The efficient model implementation based on an updated Lagrangian numerical scheme enables us to perform a large numberof simulations testing different model parameters, to find simulation results suiting 159 firn density profiles from Greenlandand Antarctica best. For most of the investigated locations a good agreement of simulated and measured firn density profileswas found. This implies that the constitutive relation by Alley (1987) characterises the fist stage of firn densification well, if10suitable model parameter are used. An analysis of the parameters that lead to best matches reveals a dependency on the meansurface mass balance. This may indicate an insufficient description of the load situation, as horizontal components of the stresstensor are usually neglected in one dimensional models of the firn column.
Do modelo cooperativo ao ambiente de negociação processual na Justiça do Trabalho: relevância da autonomia privada na nova divisão de trabalho com o juiz
Authors: Reis Sérgio
Published: March 2021

O presente artigo tem como finalidade estudar as bases ideológicas do modelo cooperativo de processo e a sua influência sobre a admissibilidade de realização de negócios jurídicos processuais atípicos. De forma específica, porém, pretende-se demonstrar que esse novo paradigma processual, que interfere, diretamente, na relação entre o juiz e as partes, deve ser aplicado na Justiça do Trabalho, rompendo com a sua tradição excessivamente voltada ao publicismo processual.
LA IMPARCIALIDAD JUDICIAL: UN TÓPICO SIEMPRE RENOVADO
Authors: ANDREA MEROI
Published: March 2021

Hace ya tiempo que la “imparcialidad judicial” reconoce límites insuperables que los avances en otras ciencias han venido a reafirmar. Si la imparcialidad es un concepto que se construye y que opera como ideal regulatorio, afirmamos que existen diseños procesales que tendencialmente favorecen la imparcialidad y diseños procesales que tendencialmente conspiran contra ella. Muchas de las opciones de los sistemas procesales que aquí se analizan reflejan, precisamente, este debate.

Augmented Reality adalah teknologi yang menggabungkan objek maya kedalam sebuah lingkungan nyata tiga dimensi dan menampilkannya dalam waktu nyata. Tidak seperti realitas maya yang sepenuhnya menggantikan kenyataan, augmented reality hanya sekedar menambahkan atau melengkapi kenyataan dengan mengijinkan penggunanya untuk berinteraksi secara real time terhadap sistem. Pada tugas akhir ini, penulis mencoba membuat salah satu metode pembelajaran dengan menggunakan bantuan augmented reality agar pembelajaran tentang sistem rotasi tata surya menjadi semakin menarik dan interaktif serta dapat menumbuhkan minat belajar masyarakat.

SMA Negeri 5 Dumai merupakan sekolah menengah negeri atas yang terletak di jalan M.Yusuf Kecamatan Medang kampai. Posisi sekolah tersebut termasuk salah satu sekolah yang jauh dari jangkauan Kota Dumai, sehingga untuk akses internet sebagai media pembelajaran secara online sangatlah minim didaerah ini. Untuk proses Ujian Nasional Berbasis Komputer (UNBK) SMAN 5 Negeri Dumai mengandalkan tower dengan jaringan internet yang telah disubsidi dari dinaspendidikan kota Dumai. Minimnya fasilitas internet untuk belajar mencari referensi secara online dan latar belakang siswa yang kurang mampu menyebabkan siswa dilingkungan SMAN 5 Dumai kurang memahami dalam pengoperasian dan penggunaan komputer sebagai media pembelajaran, sementara proses UNBK dilakukan secara online dan saat ini hampir semua sekolah yang mengikuti UNBK termasuk SMAN 5 Dumai tidak memiliki aplikasi UNBK yang bersifat lokal yang dapat digunakan siswa sebagai media training atau pelatihan. Kesenjangan antara kemampuan terhadap pengetahuan penggunaan komputer dengan kompetensi ujian yang dilakukan secara komputer membuat angka kegagalan dalam menghadapi UNBK tersebut sangat tinggi. Untuk meningkatkan kualitas siswa dalam menghadapi UNBK tersebut diperlukan suatu aplikasi e-learning ujiann online yang memuat mteri pembelajaran sebagai training atau pelatihan pembekalan kemampuan siswa sebelum menghadapi UNBK tersebut. Aplikasi E-learning ujian online tersebut dapat dijalankan secara intranet maupun secara online dengan memanfaatkan internet disekolah, dan dengan adanya Aplikasi E-learning ujian online ini menjadi solusi dalam meminimalisir angka kegagalan siswa dalam menghadapi UNBK khususnya pada SMAN 5 Dumai.

Daerah pesisir adalah daerah yang dinamis, di mana daerah pesisir mengalami proses perubahan terus-menerus dan dapat terjadi setiap saat. Oleh karena itu, dengan kemajuan teknologi dapat diamati melalui tingkat abrasi dan perubahan garis pantai terjadi di Tanjung Leban dengan menggunakan data gambar Landsat 17 tahun terakhir. Tingkat perubahan garis pantai dianalisis dengan regresi linier digital Shoreline Analysis System (DSAS). Hasil penelitian ini menunjukkan bahwa sebagian besar pantai di desa Tanjung Leban terjadi abrasi dengan berbagai tingkat abrasi. Dalam 17 tahun terakhir telah terjadi abrasi terbesar dengan 11,2 m yang terletak di jalan desa Tanjung Leban di Sungai Gayo yang posisinya jauh di ujung yang juga dekat dengan pantai Jl. Imam barokah. Hal ini mengindikasikan bahwa Tanjung Leban mengalami pengurangan luas lahan. Oleh karena itu disarankan bahwa di pantai kritis mengalami tingkat abrasi maksimum ditangani segera sehingga peristiwa abrasi tidak terus di tahun-tahun berikutnya.
