Maqashid Syari’ah Menjawab Tantangan Post-Truth Era: Urgensi Hifẓ Al-‘Aql Sebagai Penyaring Informasi
Authors: Al Wasim Arif
Published: February 2020

The development of information technology has an impact on the spread of false news, false data, and hate speech, which is difficult to control. Truth mixed with badness will be ambiguous and biased. This is the most visible symptom or symptom of the post-truth era. In this context, the concept of hifẓ al-‘aql in the maqāṣid syarī'ah can be used as a solution to deal with the negative symptoms above. This research is focused on how far the concept of hifẓ al-qaql can be used as an information filter. The data's research is library research. The data collection method uses the documentation method, which is: collecting, then analyzing the data collected. After that, data analysis is carried out by means of data reduction, presentation of data in narrative form, and concluding. This study concludes that the concept of hifẓ al-‘aql can be extended to mental and intellectual functions. The meaning of hifẓ al-‘aql is expanded by making reason as a guide, and controller for rationality (‘aqlaniyah). This expansion of meaning emphasizes that filtering information before it is conveyed to others is a must, and worthy of worship. Vice versa, the spread of news and hate speech received without verification is an action that is contrary to the principle of hifẓ al-qaql, prohibited acts, and has syar'i consequences. 
Islam, State, and Nationalism in Brunei Darussalam, India, Indonesia, and Malaysia: A Comparative Perspective
Authors: Royyani Muh Arif , Shobaruddin Muhammad
Published: February 2020

Islam has comprehensive roles in some aspects of human activity. It enlarged from theological aspect to political aspects. Some former colonized countries where Islam was coexisted, this religion became an embryo of nationalist movements during colonization era. This essay scrutinizes the role of Islam in escalating nationalism during colonization era and it relation with the states in post colonization era in four former colonized countries namely Brunei Darussalam, India, Indonesia, and Malaysia. By using comparative method, the essay researched some main literature (library research) related to Islam and nationalism. It was founded that Islam has significant roles in nationalist movement in the four analyzed countries through several channels. Meanwhile, in the post-independence era, the relation between Islam and state system are variably. In India, Islam is separated from state system (secular). In contrast, Islamic ideology became the main sources of state system in Brunei Darussalam (adopted entirely) and Malaysia (adopted partially). Then, Islam in Indonesia seems like “a gray zone” because the country does not using Islamic law but still adopting Islamic thoughts in several cases. 
Implementasi Maqashid Syariah dengan Pengembangan Ekonomi Hijau Melalui Urban Farming
Authors: Arinta Yusvita Nena
Published: February 2020

The trend of conventional economic in emerging countries raises problems in other sectors with systematic. This results in inconsistencies with the main objectives of carrying out economic activities. Economic goals are not only oriented towards wealth, but also protect the living ecosystem (hifdzu-n-nafsi) and also protect offspring (hifdzu-n-nasli). Fundamental corrections are needed to find new ways of economic development. Green economy as a new way to solve economic problems applying Maqashid Shariah. Green economy through Maqashid Shariah focuses on 3 concepts: 1) the quality of economic growth, 2) environmental efficiency, and 3) social growth. As a paradigm that is able to maintain sustainable ecosystems in achieving social economic growth by supporting welfare improvement. Urban farming is becoming a new path of discovery to develop the prosperity of implementing a green economy in Indonesia. Urban farming is an industrial cycle that produces, processes and sells food and energy to meet the needs of city consumers. All activities are carried out by the method of using and reusing natural resources and urban waste. Besides fulfilling the basic needs of every family that is the basis of a measure of money, urban farming is needed to get money with other household needs. The idea of returning to nature shows that urban agriculture is able to meet economic quality growth targets, save energy and social interaction in accordance with Islamic economic principles.

Published: February 2020

Organic symmetric disulfides have been broadly studied in various fields such
as synthetic intermediates for various organic transformations, agro-chemicals, biochemistry,
pharmacological chemistry, industrial polymers, peptidomimetics, self-assembled
monolayers (SAMs), etc. Owing to versatile applications, the search and development of
efficient, environmentally friendly, mild and inexpensive methods for the preparation of
organic disulfides play an important role in the organic functional group transformations.
Various aspects of the S–S bond formation are available in some books on organic functional
group transformations, as well as two review articles that have been published in the
years 2008 and 2014 highlighting the developments of disulfide bond formation using a
variety of reagents. However, investigations on new catalytic methods are being regularly
reported and new types of disulfides are synthesized. The present review has attempted to systematically summarize
recent catalytic advances in the process of S–S bond formation with a major focus since 2014 on highlighting
mechanistic considerations, scope, advantages, and limitations. This review does not include patent
literature.

Pregnancy, Physical Activity and Weight Control to Prevent Obesity and Future Chronic Disease Risk in Both Mother and Child
Authors: Mottola Michelle F.
Published: February 2020

Maternal obesity is accelerating world-wide and may be partly due to excessive gestational weight gain (GWG) and weight retention so that women begin a subsequent pregnancy with extra weight. Excessive GWG has been linked to chronic disease risk in the mother and also to an unhealthy foetal environment with downstream consequences for offspring health with risk for childhood obesity. Weight control during pregnancy and prevention of excessive GWG is an important issue for both mother and developing child. A healthy lifestyle through healthy eating and physical activity are key to prevention. Weight management for non-pregnant individuals has been evaluated for over 30 years, and lessons learned may assist in planning interventions for preventing excessive GWG. Many systematic reviews and meta-analyses analyzing the same studies on GWG report very different results. Recently, 10 intervention trials to prevent excessive GWG were published and only 6 of them were successful. Significant association between maternal exercise and GWG guidelines were reported, however, “one size does not fit all”. The failed trials did not have extra faceto- face sessions, were educational based and adherence was <50%. Accountability, face-to-face exercise sessions, and pedometers may motivate pregnant women to increase step counts to 10,000, which, when combined with nutrition control, prevents excessive GWG. Community walking programs that include family members and children may assist pregnant women of all body mass index categories to overcome potential barriers to promote a healthy lifestyle that will benefit them and their families for weight control and prevention of future chronic disease risk.

Authors: Kumar Manish , Shanthi Nithya , Rajnikanth P.S. , Mahato Arun Kumar
Published: February 2020

In the last few decades, researchers and pharmaceutical industries have been
developing new approaches to overcome the solubility and bioavailability limits observed
with poorly soluble drugs. With the advancement of nanotechnology, nanocrystals have
emerged as a great potential to overcome these limitations. Nanocrystals owing to its ability
to modify the physicochemical and biological properties of the drug have gained widespread
attention among the research scientists. This review provides comprehensive detail
on the associated advantages, challenges, factors affecting physicochemical properties,
and optimization parameters about the stability of nanocrystals. In this review, the evolution
of nanocrystals is discussed as first-generation simple nanocrystals, secondgeneration
nanocrystals within a carrier, and third-generation surface-modified nanocrystals.
It also provides a detailed account of various preparation methods and evaluation of
surface-modified nanocrystals. In the proposed "King Design," nanocrystals of the third
generation are placed on the top due to their advantage over other nanocarriers like high
drug payload, site-specific delivery, improved activity, commercial manufacturing, and
easy scale-up. Third generations nanocrystals can provide a novel therapeutic solution for
the site-specific, targeted, and efficient delivery for treatment of various acute as well as
chronic diseases with high stability and scale-up potential.

Peer Support in Mental Health: Literature Review
Authors: Shalaby Reham A Hameed , Agyapong Vincent I O
Published: February 2020

Background

A growing gap has emerged between people with mental illness and health care professionals, which in recent years has been successfully closed through the adoption of peer support services (PSSs). Peer support in mental health has been variously defined in the literature and is simply known as the help and support that people with lived experience of mental illness or a learning disability can give to one another. Although PSSs date back to several centuries, it is only in the last few decades that these services have formally evolved, grown, and become an integral part of the health care system. Debates around peer support in mental health have been raised frequently in the literature. Although many authors have emphasized the utmost importance of incorporating peer support into the health care system to instill hope; to improve engagement, quality of life, self-confidence, and integrity; and to reduce the burden on the health care system, other studies suggest that there are neutral effects from integrating PSSs into health care systems, with a probable waste of resources.

Objective

In this general review, we aimed to examine the literature, exploring the evolution, growth, types, function, generating tools, evaluation, challenges, and the effect of PSSs in the field of mental health and addiction. In addition, we aimed to describe PSSs in different, nonexhaustive contexts, as shown in the literature, that aims to draw attention to the proposed values of PSSs in such fields.

Methods

The review was conducted through a general search of the literature on MEDLINE, Google Scholar, EMBASE, Scopus, Chemical Abstracts, and PsycINFO. Search terms included peer support, peer support in mental health, social support, peer, family support, and integrated care.

Results

There is abundant literature defining and describing PSSs in different contexts as well as tracking their origins. Two main transformational concepts have been described, namely, intentional peer support and transformation from patients to peer support providers. The effects of PSSs are extensive and integrated into different fields, such as forensic PSSs, addiction, and mental health, and in different age groups and mental health condition severity. Satisfaction of and challenges to PSS integration have been clearly dependent on a number of factors and consequently impact the future prospect of this workforce.

Conclusions

There is an internationally growing trend to adopt PSSs within addiction and mental health services, and despite the ongoing challenges, large sections of the current literature support the inclusion of peer support workers in the mental health care workforce. The feasibility and maintenance of a robust PSS in health care would only be possible through collaborative efforts and ongoing support and engagement from all health care practitioners, managers, and other stakeholders.
Using the Preparation Phase of the Multiphase Optimization Strategy to Develop a Messaging Component for Weight Loss: Formative and Pilot Research
Authors: Pfammatter Angela Fidler , Marchese Sara Hoffman , Pellegrini Christine , Daly Elyse , Davidson Miriam , Spring Bonnie
Published: February 2020

Background

Mobile messaging is often used in behavioral weight loss interventions, yet little is known as to the extent to which they contribute to weight loss when part of a multicomponent treatment package. The multiphase optimization strategy (MOST) is a framework that researchers can use to systematically investigate interventions that achieve desirable outcomes given specified constraints.

Objective

This study describes the use of MOST to develop a messaging intervention as a component to test as part of a weight loss treatment package in a subsequent optimization trial.

Methods

On the basis of our conceptual model, a text message intervention was created to support self-regulation of weight-related behaviors. We tested the messages in the ENLIGHTEN feasibility pilot study. Adults with overweight and obesity were recruited to participate in an 8-week weight loss program. Participants received a commercially available self-monitoring smartphone app, coaching calls, and text messages. The number and frequency of text messages sent were determined by individual preferences, and weight was assessed at 8 weeks.

Results

Participants (n=9) in the feasibility pilot study lost 3.2% of their initial body weight over the 8-week intervention and preferred to receive 1.8 texts per day for 4.3 days per week. Researcher burden in manually sending messages was high, and the cost of receiving text messages was a concern. Therefore, a fully automated push notification system was developed to facilitate sending tailored daily messages to participants to support weight loss.

Conclusions

Following the completion of specifying the conceptual model and the feasibility pilot study, the message intervention went through a final iteration. Theory and feasibility pilot study results during the preparation phase informed critical decisions about automation, frequency, triggers, and content before inclusion as a treatment component in a factorial optimization trial.

Predictive Modeling for Frailty Conditions in Elderly People: Machine Learning Approaches
Authors: Tarekegn Adane , Ricceri Fulvio , Costa Giuseppe , Ferracin Elisa , Giacobini Mario
Published: February 2020

Background

Frailty is one of the most critical age-related conditions in older adults. It is often recognized as a syndrome of physiological decline in late life, characterized by a marked vulnerability to adverse health outcomes. A clear operational definition of frailty, however, has not been agreed so far. There is a wide range of studies on the detection of frailty and their association with mortality. Several of these studies have focused on the possible risk factors associated with frailty in the elderly population while predicting who will be at increased risk of frailty is still overlooked in clinical settings.

Objective

The objective of our study was to develop predictive models for frailty conditions in older people using different machine learning methods based on a database of clinical characteristics and socioeconomic factors.

Methods

An administrative health database containing 1,095,612 elderly people aged 65 or older with 58 input variables and 6 output variables was used. We first identify and define six problems/outputs as surrogates of frailty. We then resolve the imbalanced nature of the data through resampling process and a comparative study between the different machine learning (ML) algorithms – Artificial neural network (ANN), Genetic programming (GP), Support vector machines (SVM), Random Forest (RF), Logistic regression (LR) and Decision tree (DT) – was carried out. The performance of each model was evaluated using a separate unseen dataset.

Results

Predicting mortality outcome has shown higher performance with ANN (TPR 0.81, TNR 0.76, accuracy 0.78, F1-score 0.79) and SVM (TPR 0.77, TNR 0.80, accuracy 0.79, F1-score 0.78) than predicting the other outcomes. On average, over the six problems, the DT classifier has shown the lowest accuracy, while other models (GP, LR, RF, ANN, and SVM) performed better. All models have shown lower accuracy in predicting an event of an emergency admission with red code than predicting fracture and disability. In predicting urgent hospitalization, only SVM achieved better performance (TPR 0.75, TNR 0.77, accuracy 0.73, F1-score 0.76) with the 10-fold cross validation compared with other models in all evaluation metrics.

Conclusions

We developed machine learning models for predicting frailty conditions (mortality, urgent hospitalization, disability, fracture, and emergency admission). The results show that the prediction performance of machine learning models significantly varies from problem to problem in terms of different evaluation metrics. Through further improvement, the model that performs better can be used as a base for developing decision-support tools to improve early identification and prediction of frail older adults.
Developing a Shared Understanding of a Sense of Community in Large Classes
Authors: Francis Tryon , Kennedy-Clark Shannon , Eddles-Hirsch Katrina , A’Beckett Cynthia
Published: February 2020

Over the past ten years, universities and other tertiary level institutions have seen a considerable increase in student enrolment. This has led to larger class sizes both in the lecture hall and tutorial classroom. Research has indicated that larger classes at the tertiary level have not only burdened teaching staff, but have also led to student disengagement in the lecture hall. Students, new to university life, have been found to be particularly unprepared for this type of learning environment. This project explores the shared understanding of how to create a sense of community in large class sizes within a School of Education. Three academics formed a partnership in an effort to share techniques that actively created a sense of community in lecture halls of over 200 students. This research is relevant not only in highlighting this problem, but in the sharing of recommendations and suggestions for large group teaching.

Published: February 2020

La política de diversificación de la carga instaurada en los noventa dio auge a acciones encaminadas a la formación de redes y cuerpos académicos, la introducción del concepto de perfil de desempeño equilibrado, y el comienzo de los programas de estímulo al desempeño académico. A su vez, se trató de una política que incrementó las demandas laborales transformando el quehacer académico. Este artículo analiza cómo ha sido la diversificación de las funciones de los investigadores, el rol que han jugado los programas de incentivos, y la forma en la que han respondido tanto los investigadores como los integrantes de los espacios en los que se desempeñan. Éste es un trabajo que abona a los estudios organizacionales de la universidad ayudándonos a entender cómo cambia la naturaleza de las figuras, sus roles y funciones, conjuntamente con la universidad que los acoge. Ilustra algunas de las disyuntivas enfrentadas por los investigadores a partir de la implementación de políticas financieras impulsadas por mecanismos de evaluación, medición y recompensa.

Authors: Gràcia Marta , Jarque Maria-Josep , Astals Marta , Rouaz Kholoud
Published: February 2020

La educación de los futuros maestros necesariamente debe incluir el desarrollo de la competencia comunicativa por su carácter fundamental como instrumento de comunicación, de producción y transformación del conocimiento y para la mejora de la calidad de los aprendizajes, así como para favorecer el desarrollo del pensamiento crítico, tanto en relación con los propios estudios como con su posterior desempeño profesional. A pesar de ello, son pocos los estudios e investigaciones dedicados a ello. El propósito de este artículo es contribuir a llenar este vacío mediante la presentación de los resultados de un estudio, cuyo objetivo estriba en la mejora de la construcción de textos orales argumentativos y la reflexión metalingüística sobre sus elementos, mediante el desarrollo e introducción de estrategias e instrumentos docentes. Se utilizó un método mixto, que incluye análisis cuantitativos y cualitativos. Los instrumentos utilizados fueron la EVALOE o Escala de Evaluación de la Lengua Oral en contexto Escolar (Gràcia et al., 2015a) y una rúbrica construida al efecto. Los resultados muestran que si se introducen estrategias e instrumentos docentes ajustados, los estudiantes aprenden a construir textos (monogestionados y plurigestionados) y a reflexionar sobre ellos.
DIVERSIFICATION OF THE PEASANTS’ RATIONALITY AS STREET VENDORS IN JUNREJO, BATU CITY
Authors: Rosyidin Aditya Danan
Published: February 2020

In the range of 2009 to 2013, agricultural production in Batu City declined. The impact of this decline in agriculture has made farm labor economically difficult. This makes the farm laborers begin to abandon their fighting activities. This phenomenon makes the diversification of the rationality of the work of farm labors into street vendors. The purpose of this study was to describe the scheme of voluntaristic action of farm laborers in achieving their economic needs in the street vendor sector, as well as to describe the rationality of the diversification of farm laborers’ jobs into street vendors in the Junrejo District of Batu City. This study uses a qualitative approach with descriptive type. The subjects of the study were farm laborers who chose to leave work as farm laborers to turn into street vendors and farm laborers who still remained farm laborers but also worked as street vendors. The technique of collecting data uses observation, interviews, and documentation, while the data analysis technique uses data reduction, data categorization, synthesis. The technique of checking the validity of the data uses persistent observation, triangulation, and peerderieting. The results of this study are that the scheme of voluntaristic action of farm laborers in achieving their economic needs in the street vendors sector starts from the rapid tourism in Batu City. Farm workers have actions towards sluggish agriculture by utilizing the development of tourism in Batu City. Some of their actions were to become street vendors in the Batu City Square area, open another business and become an online driver. One of the rational actions of farm workers is to diversify work. Farmers in diversifying their work are based on consideration of the work of farm labors who are very heavy and have little income. The aim of farm workers in diversifying their work is to obtain greater profits compared to the work of farm workers.
Technoliberalism in Iceland: The Fog of Information Infrastructure
Authors: Von Bargen Julian , Fish Adam
Published: February 2020

Background  In the wake of the 2007–2008 financial crisis in Iceland, some citizens believed the calamity was the outcome of a cultural of secrecy among the political and financial elites.Analysis  By examining an effort to legislate for a “data haven” in Iceland, this article discusses a shift in how data activists attempted to achieve data justice. This shift challenges existing ideas about cyberlibertarian and technoliberal approaches to social change. In attempting to address the inequalities inherent to the centralization of data and the internet, data activists moved away from advocacy and adopted two previously rejected strategies: formal political organizing and territorial authority.Conclusion and implications  Activism for data equity was insufficient to counter existing data power in Iceland. What comes after technoliberalism?Contexte  Suivant la crise financière de 2007-2008 en Islande, certains citoyens se mirent à penser que ce désastre était le résultat d’une culture du secret parmi les élites politiques et financières du pays.Analyse  Par l’examen d’efforts pour légiférer un « havre de données » en Islande, cet article discute d’un changement dans la manière dont des militants ont tenté d’établir un accès plus juste aux données. Ce changement pose un défi à des idées courantes prônant une approche cyberlibertaire et technolibérale envers le changement social. Les militants, en tentant de s’adresser aux inégalités inhérentes à la centralisation des données et d’internet, se sont éloignés du plaidoyer pour adopter deux stratégies rejetées antérieurement : l’organisation politique formelle et l’autorité territoriale.Conclusion et implications  Le militantisme pour l’égalité des données s’est avéré insuffisant pour démocratiser le contrôle des données en Islande. Dans ces circonstances, qu’est-ce qui pourrait suivre au technolibéralisme?

Panorama histórico da formação dos professores de ciências
Authors: Santos Claudení Marques , Souza Lucia Helena Pralon de
Published: February 2020

Este artigo pretende compreender de que maneira as Leis de Diretrizes e Bases da Educação Nacional (LDB) e respectivas alterações contemplaram a formação dos professores de Ciências e Biologia apontando as principais problemáticas e implicações, a partir de uma perspectiva histórica. Por meio de análise documental e bibliográfica destacou-se que há uma herança histórica na licenciatura do modelo “3 + 1”, caracterizada como apêndice do bacharelado, levando a não identificação do perfil do professor formado; a separação dos conhecimentos em científicos e pedagógicos desse modelo fragmentou ainda mais o currículo do curso; a má qualidade das licenciaturas criadas, principalmente via iniciativa privada, após LDB/96, formou professores desqualificados prejudicando a aprendizagem do ensino. Em última análise, atuais modificações na LDB retrocedem ao atestar a possibilidade de se atribuir o exercício da docência a pessoas com “notório saber”. Pontua-se a relevância de se recorrer aos textos legais, uma vez que a forma como a formação de professores é abordada revela, também, a importância atribuída a este campo por determinado grupo social em seu conjunto.

Untuk mendapatkan bahan kimia yang ramah lingkungan adalah memanfaatkan potensi alam yaitu tanaman yang mengandung bioinsektisida. Salah satu tanaman yang sangat potensial untuk dikembangkan sebagai bioinsektisida adalah Dioscorea hispida Dennst atau dikenal dengan nama gadung. Tujuan penelitian ini adalah untuk mengetahui efektivitas ekstrak tanaman gadung dalam mengendalikan jentik nyamuk. Jenis penelitian yang digunakan yaitu true eksperimental dengan desain posttest only control group design. Sampel dalam penelitian ini adalah jentik instar III yang tersedia di Laboratorium Litbang P2B2 Tanah Bumbu. Jumlah pengulangan untuk setiap kelompok sebanyak 9 kali dan setiap pot percobaan diisi 15 jentik instar III. Setiap pos berisikan air 100 ml dengan konsentrasi ekstrak umbi dan daun gadung 0,20%. Untuk melihat perbedaan rerata kematian jentik antara kelompok intervensi dilakukan analisis Uji Kruskal Wallis. Kematian jentik terjadi pada seluruh kelompok intervensi. Kelompok intervensi yang efektif adalah ekstrak umbi gadung 0,2% karena dapat mematikan rata-rata 45% jentik selama 24 jam waktu perlakuan. Ada perbedaan yang bermakna dari ekstrak tanaman gadung terhadap kematian jentik, p value= 0,000  (0,05). Perlu dilakukan penelitian lanjutan dengan membandingkan ekstrak tanaman yang berbeda dan berpotensi sebagai insektisida alami dalam mengendalikan jentik.

Når man kigger på det internationale bibliotekslandskab, står især ét land særligt skarpt for tiden, og det er Finland. Med store satsninger inden for Open Science, virtual reality og kunstig intelligens på tværs af bibliotekssektoren - og ikke mindst publikumssuccesser som Helsinkis storslåede nye hovedbibliotek, Oodi, - har finnerne positioneret sig som en frontløber, og et land vi andre kan lade os inspirere af. I december 2019 sendte Det Kgl. Bibliotek derfor en delegation afsted til det kolde nord for at undersøge, hvad vi kan lære af vores biblioteksglade naboer mod nordøst.

The stability and convergence time become an essential factor in network availability performance. Multiprotocol Label Switching (MPLS) is one of the Virtual Private Network (VPN) technologies that can support the quality of communication media on the high-speed backbone network. Therefore, it is necessary to determine the proper protocol routing in espousing VPN technology based on MPLS supported by direct-link backup to improve network availability in the Data Center. The purpose of this study is comparing the convergence time and Quality of Service (QoS) among the three IGP protocols routing, namely Routing Information Protocol version 2 (RIP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP) based on two autonomous system number using Ring topology design between Data Center and DRC. Network scenario is created using the Graphic Network Simulator (GNS3) application to measure convergence time and QoS parameters of the three protocols routing and the use of MPLS-TE and RR in enhancing MPLS backbone performance. The results revealed that QoS in the three protocols routing has a good quality level according to TIPHON’s standard with the number of indexes up to 3.25 (Good). On the other hand, the fastest convergence time when interruption on the main link (VPN) is EIGRP with convergence time for about 15 seconds.
THE EFFECT OF POLYSILAZANE ON THE DENSIFICATION AND MECHANICAL PROPERTIES OF SICF/SIC COMPOSITES
Authors: Noviyanto Alfian
Published: February 2020

The effect of polysilazane on the densification and mechanical properties of SiCf/SiC composites was examined thoroughly. The polysilazane was infiltrated into the fiber area, followed by pyrolysis at 1450°C for 4 h in an argon atmosphere. Furthermore, the SiC fabrics contain the pyrolyzed polysilazane was infiltrated by β-SiC slurry and sintered at 1750°C for 2 h in an argon atmosphere. The density of SiCf/SiC composites with and without the addition of polysilazane was 2.65 and 3.05 g/cm3, respectively. The pores in the fiber area were observed for the SiCf/SiC composites with the addition of polysilazane. However, the fine-grained size in the matrix area was obtained by the addition of polysilazane. The average grain size of the SiCf/SiC composite with and without the addition of polysilazane was 253 and 740 nm, respectively. Indeed, the hardness of the matrix area for SiCf/SiC composites with the addition of polysilazane (31.6 ± 1.8 GPa) was higher compared to SiCf/SiC composites without polysilazane (27.4 ± 1.6 GPa).
ELMAN-RECURRENT NEURAL NETWORK FOR LOAD SHEDDING OPTIMIZATION
Authors: Aribowo Widi
Published: February 2020

Load shedding plays a key part in the avoidance of the power system outage. The frequency and voltage fluidity leads to the spread of a power system into sub-systems and leads to the outage as well as the severe breakdown of the system utility.  In recent years, Neural networks have been very victorious in several signal processing and control applications.  Recurrent Neural networks are capable of handling complex and non-linear problems. This paper provides an algorithm for load shedding using ELMAN Recurrent Neural Networks (RNN). Elman has proposed a partially RNN, where the feedforward connections are modifiable and the recurrent connections are fixed. The research is implemented in MATLAB and the performance is tested with a 6 bus system. The results are compared with the Genetic Algorithm (GA), Combining Genetic Algorithm with Feed Forward Neural Network (hybrid) and RNN. The proposed method is capable of assigning load releases needed and more efficient than other methods.

The telecommunication has a tremendous improvement in terms of data rates and bandwidth requiring sufficient frequency allocation and wideband spectrum availability. The millimeter-wave frequency band is one of the solution to these requirements, however communications in this band is facing new challenges on the climate effect to the channel propagation  In this paper, we propose a 5G channel model considering the effect of humidity based on the characteristic of the natural environment of Palembang city. The channel model is represented by power levels and delay called a Power Delay Profile (PDP and is derived based on a series of computer simulations using parameters of nature in Palembang. The 5G channel model is important to further derive the outage performance to be used as the theoretical performance of 5G in Palembang since the the Shannon Channel Capacity Theorem is involved in the derivation. We conduct a series of computer simulations to evaluate the validity of the proposed channel model and its characteristics. We found that humidity affect to the performances, where high humidity makes the performances of outage and BER slightly worse, although the effect may be ignored for some applications. The results of this paper are expected to be the references for the development and implementation of 5G Networks especially at the mm-Wave band in Palembang.
