Authors: Khikmah Khusnia Nurul
Published: March 2022

Natural phenomena that can cause natural changes on earth caused by increasing greenhouse gases and decreasing landthat absorbs carbon dioxide are called climate change. The elements that cause changes include rainfall and temperature.The constantly rising temperature of the earth results in changing rainfall patterns and can have various effects on theenvironment. Therefore, research on rainfall modeling with annual average temperature and rainfall data from theprovince of East Java from 2006 to 2017 which was taken from the official website of the Central Statistics Agency ofEast Java Province makes sense. This data is a data multivariate time series that is approached with Functional DataAnalysis and modeled using Functional Prediction Regression. Functional Prediction Regression is a form of modelingwith functional data that can test the overall model for high-dimensional data and one of the improved methods ofregression methods for functional data. One way to model Functional Prediction Regression is through boosting. Thisresearch conducted rainfall modeling with Functional Prediction Regression through boosting from East Java Provinceand obtained modeling results using an additional predictor model with 5-fold bootstrap and adjustment of the splineregression (knots) used, namely 16 indicated by the iteration value-boosting bootstrap where the model used to have alinear functional effect of 𝑚𝑠𝑡𝑜𝑝 for the mu parameter and 100 for the sigma parameter.

Authors: Azis Tukhfatur Rizmah
Published: March 2022

Pembelajaran online telah dilakukan oleh beberapa dosen maupun siswa dalam menyampaikan dan menerima materi. Hal ini biasa dilakukan dengan memberikan video di platform kelas online atau mengajak bergabung dalam ruang obrolan online. MOOC atau Massive Open Online Course adalah salah satu platform kursus online yang telah digunakan oleh kalangan dosen, peneliti, dan siswa dengan menyuguhkan video pembelajaran kepada siswa dari dosen. Namun setelah adanya pembelajaran online terdapat perbedaan perilaku siswa ketika menerima pembelajaran online dan offline. Tidak seperti pendidikan di kelas, di mana guru dapat menilai apakah siswa dapat memahami materi melalui pertanyaan verbal atau bahasa tubuh mereka. Maka dalam hal ini penelitian akan difokuskan pada salah satu permasalahan yakni mendeteksi tingkat kebingungan pada siswa saat menonton video pembelajaran dengan menggunakan metode Support Vector Machine (SVM) dan data sinyal electroencephalography (EEG). Analisis dilakukan dengan melakukan perbandingan nilai ketepatan klasifikasi dari tiga fungsi kernel SVM yakni linear, Radial Basic Function (RBF), serta Polinomial Regresi. Berdasarkan pengolahan data yang telah diperoleh pada metode SVM Linear pada pre-defined label mendapatkan hasil akurasi mencapai 63,16% pada user-defined label mendapatkan hasil akurasi mencapai 63,16%. Sedangkan metode Polinomial Regresi pada pre-defined label mendapatkan hasil akurasi mencapai 68,42%, pada user-defined label mendapatkan hasil akurasi mencapai 57,89%.  Serta metode RBF pada pre-defined label mendapatkan hasil akurasi mencapai 63,16% pada user-defined label mendapatkan hasil akurasi mencapai 57,89%. Hal ini menunjukkan bahwa metode SVM dapat digunakan untuk mengklasifikasikan data sinyal EEG.

Profiling Student Teachers Tendencies on Peer Review Production
Authors: Rahmawati Eva
Published: March 2022

ABSTRACT This is a report of a preliminary study focused on investigating student teachers tendencies of peer review production. The research is a basis for a more comprehensive research aiming to explain how the aforementioned tendencies affect the effectiveness of peer review. The data collected were in the form of students written commentaries taken from three expository and argumentative essay writing assignments. These data were collected from eight students, four high achievers and four low achievers. On the courses first meeting, an essay writing proficiency test was administered to determine researchs participants and dyads involved. To prepare students with peer review practice, a peer review tutorial and rubrics were also given on the first meeting of the course. Following this stage, students written commentaries were collected as data, which were then codified following the typology of written feedback by experts. Codification results were interpreted by comparing them to previous related research. In doing so, it was apparent that low achievers tend to produce commentaries on surface structure errors. As oppose to this, organization and content-focused commentaries were dominant in high achievers feedbacks. These findings are noteworthy, as they suggest a link between students proficiency level and their preferred commentary focus.Keywords: academic writing, peer review production, student teacher, commentary provision tendency.

Modified Peer Written Corrective Feedback on Dialogue Drafting of Twelfth Graders: Focusing on Linguistic Features
Authors: Lasti'ah Lasti'ah
Published: March 2022

Writing skill is regarded as troublesome for students, leading to errors occurring in the students’ writing. Thus, this paper aims to explore the linguistic feature errors in students' writing and how those errors can be minimized by modified peer-written corrective feedback. This study employed a qualitative method with Classroom Action Research (CAR) design through content analysis. The data was collected from vocational high school students’ composition of the dialogue draft on the ‘offering help’ theme. The results reveal that apart from their level of proficiency, students make errors more on linguistic features in their first phase than in their second phase. It is due to the role of modified peer-written corrective feedback given by their peers of different groups. This feedback assists the students in learning their linguistic aspect errors in their writing. In the process of writing, the modified written corrective feedback is imperative to spur students to apply good linguistic features in their writing. In such a case, learning from peer feedback is a good technique since the process becomes the priority rather than the final product. Finally, modified peer-written corrective feedback is effective in enhancing the students’ writing skills, particularly in writing dialogue.

The existence of coffee shops in Surabaya is now increasingly spreading in various areas which has now become a problem in the administrative compliance of SIUP management. So that there is a need for government efforts to bring order to business actors in obeying the administration. Surabaya Mayor Regulation N0.41/2021 concerning business licensing, non-business licensing and non-licensing services. With this regulation, the Surabaya city government issued a policy for every MSME business actor, coffee shops, cafes and coffee shops to have a SIUP. After the issuance of the policy, there are still many MSME business actors who have not pocketed SIUP. Thus, it is necessary to know how to implement the Trade Licensing Policy for coffee shop MSME business actors in Wiyung sub-district, Surabaya city. In the process of this research using descriptive qualitative research with techniques to collect data from observations and interviews with DPM-PTSP Surabaya City and District Wiyung Surabaya. From the results of research conducted by researchers, it is stated that from The Accuracy of The Policies Implemented, it can run well in line with the regulations issued by the Surabaya city government that business actors who are non-KTP Surabaya can manage SIUP. The accuracy of the implementation is not optimal because there are still business actors who have not pocketed SIUP. Target accuracy is also less than optimal because there are still business actors who have minimal technological knowledge in managing SIUP in the Online Single Submission (OSS) System online. Environmental Accuracy is also going well from the internal point of view of the policy implementer, but from the external point of view it still looks bad, namely the lack of contribution from business actors in implementing the mandatory SIUP.

Authors: Chibisa Admire , Mutambara David
Published: March 2022

Every child has a right to education and attending school is a must in South Africa. However, school attendance was severely disrupted by the Covid-19 pandemic outbreak. Regardless, the academic process has to continue, hence the use of mobile devices as pedagogical tools for learning. The aim of this study therefore is to explore the determinants of high school learners' continuous use of mobile learning in order that the academic project may continue. The study employed a survey design in which quantitative data were collected using a seven-point Likert-type scale questionnaire developed by the researchers. A stratified sample of 500 high school learners participated in the survey of which 419 of them successfully completed the survey, giving a success rate of 83.8%. The remaining 16.2% submissions were spoilt and hence discarded. The study combined three models, namely the technology acceptance model (TAM), self-determination theory (SDT), and the expectation-confirmation model (ECT) in its analysis of the developed seven-construct model which used partial least squares structural equation modelling (PLS-SEM). SmartPLS v 3.0 was used to validate the measurement and structural models of the study. Results showed that all six variables identified for the model were good predictors of high school learners’ continuous use of mobile learning with 68% explained variance for satisfaction and 39.1% for continuous use. The study developed and validated a robust mobile learning model which is recommended to stakeholders for continuous use of mobile learning. Future researchers are encouraged to search for more determinants of continuous use of mobile learning that have not been identified in this study.

Speaking skills can be considered a key measure of success in learning a language. Learning Tamil, as an elective language in Malaysian National Primary schools, is extremely difficult for beginners compared to students in National Type Tamil Primary Schools in Malaysia. The aim of the research is to apply digital storytelling as a pedagogical approach in speaking classes in national primary schools with a view to promote Tamil speaking abilities of children. A collaborative quasi-experimental action research design was adopted to measure the efficacy of digital storytelling in enhancing students’ Tamil speaking skills. Action research was conducted with thirteen 2nd standard students aged between 7 and 8 years old, in a national primary school, in Pasir Gudang district, Johor, on a pilot project. The Tamil digital storytelling modules were developed in a mobile application with pre-and post-test survey tools and the respective class teachers were trained on the module to work with children in a regular classroom setting. The results showed that significant improvements were observed in students' comprehension, vocabulary, and fluency elements of the speaking skills after their participation in the digital storytelling sessions. As a result, the study suggests that digital storytelling may be an effective pedagogical approach to enhance students’ speaking abilities in the classroom and beyond to improve the students’ mother-tongue as second-language learning in schools.

O cenário atual permite compreender que a comunicação organizacional se caracteriza, cada vez mais, como um movimento de interpretação e reinterpretação das relações sociais, nas quais os diversos atores envolvidos, de diversas culturas, agora também produtores de informação, atuam na construção de sentido. Frente a esse cenário, apresenta-se a problemática da pesquisa que motivou o presente artigo: como promover competências interculturais e em comunicação, em graduandos de Relações Públicas, por meio de plataformas digitais, considerando aspectos interacionais e a cultura da conexão? O objetivo central foi analisar o uso de uma mídia social por um grupo de alunos do Brasil e de Portugal à luz da interação intercultural. O percurso metodológico foi desenvolvido em duas etapas: 1) pesquisa bibliográfica e 2) análise da interação entre o grupo de alunos a partir de uma mídia social, com recursos educacionais abertos e voltada à coaprendizagem. A análise dos resultados baseada na netnografia e na análise de conteúdo aponta para a necessidade de criar meios concretos de interação na formação do profissional de Relações Públicas.

A proposta deste artigo é apresentar os resultados preliminares do Observatório Brasileiro de Violência Online, o qual promoveu uma análise do material jornalístico publicado nos portais G1 e Uol no período de 12 anos, de 2007 a 2019. Tais resultados contribuem porque apresentam dados primários sobre a questão da violência online no país, visto que tal fenômeno padece de profunda escassez de dados e de produção científica de maneira geral. Como base teórica, buscou-se referências nacionais e internacionais que tratam do tema violência online. Desde de um ponto de vista metodológico, utilizou-se a pesquisa exploratória amparada na técnica de coleta e análise de dados de observação sistemática associada à Análise de Conteúdo, com abordagem qualitativa e quantitativa. No total, foram coletados 3.517 materiais jornalísticos que tratavam sobre algum tipo de violência e destes 390, especificamente, sobre violência online. Como principais achados, destacamos o crescente número de casos publicados nos supracitados jornais. Além disso, constatamos que a grande maioria dos casos traz como vítima mulheres e como agressores homens. Destacamos também que os principais tipos de violência são crimes contra honra, vazamento de imagens íntimas sem consentimento e discurso de ódio.

Authors: Bona Rafael José , Wosniak Cristiane
Published: March 2022

Through interdisciplinary research involving education and cinema, the article aims to analyze the narrative of the film Central Station (1998), directed by Walter Salles, and identify elements for teaching three-act narratives in a script. The research is classified as descriptive and documentary, with a qualitative approach, and uses the film analysis technique. The main result was the realization that the practice of teaching scripts, from the cinema itself, is an essential issue to encourage discussions, deepen studies and instigate creative ideas. It is also found that Central Station is not a film that only allows the teaching of three-act narrative, but also promotes discussions in the most different spheres, whether to issues related to the Brazilian social scene, senior people, and their relationship with work, culture, and national folklore.
Los Sentidos del anticorreísmo: análisis de los memes de Crudo Ecuador
Authors: Gordillo Vargas Edison
Published: March 2022

La contienda entre el Correísmo y el anticorreísmo se hace visible en una página de Facebook,  por un lado el poder de las redes sociales, por el otro el poder estatal. Ambos personajes de esta contienda  al día de hoy son actores muy importantes de la política ecuatoriana. Esta disputa llegaría hasta oídos de Oliver Stone en Inglaterra produciendo su mofa ante las cámaras y televidentes. Correa denunciaba a Crudo Ecuador por un ataque sistemático en contra de su figura, Crudo Ecuador se defendía tras la libertad de expresión. Todos estos sucesos bajo el manto de memes y producción audio visual. Este trabajo presenta a los memes y sus marcos de sentido como minúsculos mensajes compartidos a través de las redes produciendo significados. Para el estudio de los memes se propone una metodología mixta: cuantitativa y cualitativa, entorno a la obtención de datos y clasificación en función de marcos de sentido empleados.
Resistencia y flexibilidad de la escritura en internet o cómo la territorialidad digital puede influir su mutación.
Authors: Nava La Corte Fernando
Published: March 2022

Las dinámicas comunicacionales que se viven en la actualidad se deben primordialmente a la tecnología y a las narrativas de diferentes públicos contemporáneos en el ámbito de los medios digitales, lo anterior vislumbra también una cierta resistencia y flexibilidad en la realidad de las personas tanto en escritura como en locución. Para comprender con mayor profundidad y transcendencia estos procesos comunicativos en este artículo nos interesó explorar la mutación de palabras y expresiones escritas dentro de las diversas formas de comunicación digital que circulan en Instagram, Twitter y WhatsApp. Se utilizó el método de análisis de contenido para dilucidar el tratamiento simbólico dado a cada una de ellas y el impacto que logran en la cultura digital. Posteriormente se estudió la función informativa que desempeñan estos ensamblajes en la acción de escribir, de la cual se obtuvo una narrativa heteróclita que logró captar la atención a partir del uso de la coherencia, vituperios, contracciones o errores ortográficos intencionales; distinguir estas transgresiones ortográficas conlleva a una tendencia de la lengua escrita en internet que es clave indispensable para la comprensión de preocupaciones y prácticas socio digitales. Los resultados obtenidos sugieren la existencia de mecanismos de inmediatez comunicativa y autenticidad que pueden ser aprovechados en el ámbito cultural y educativo, pues ayudan a reproducir estrategias lúdicas de aprendizaje y lenguajes múltiples que superan la formalidad sin caer en lo superficial.

crisis institucional del SARS-CoV-2 en México: percepciones y representaciones sociales
Authors: Espinosa Marquez Araceli , Rios Calleja Carla Irene , Hermida Quezada Rosa María
Published: March 2022

a comunicación institucional, como fuente de primer orden, influye en los medios de comunicación y en la ciudadanía (McNair, 2011).  Partimos de la idea de que la palabra, como concentradora de grandes significados, permite a los individuos asociar sus interacciones bajo narrativas comunes en un mismo contexto, resultando así, una realidad social consensuada (Berger y Luckmann, 2003; Schrøder, 2015). De tal manera que, al interpretar la representación social del SARS-CoV-2 (Covid-19) enunciada por el vocero oficial de salud en México, y compararla con los primeros resultados de una encuesta nacional, aplicada a mayores de 18 años con diferentes grados de escolaridad y que estuvieran viviendo en el país durante la pandemia, se amplía y enriquece la comprensión de la percepción ciudadana. De manera que resulta posible analizar la forma en que los mensajes institucionales incidieron en el constructo social de la ciudadanía. Esta investigación se centra en conocer cómo perciben los ciudadanos en México el manejo institucional sobre esta crisis sanitaria emergente durante el mes de abril de 2020, contrastándolo con las versiones estenográficas de las primeras conferencias vespertinas del vocero de salud aplicando el análisis crítico de discurso como herramienta teórico-metodológica.
Contienda discursiva entre multilateralismo y nacionalismo entorno a la paz global, el cambio climático y la pandemia: Los discursos de Trump, Bolsonaro, Jinping y Putin en la ONU
Authors: Cunha-Mata Argenis , Mila Maldonado Andrea del Carmen , Mila Juan
Published: March 2022

El presente artículo tiene como objetivo, a partir de criterios teóricos del nacionalismo y el multilateralismo, analizar las construcciones discursivas (en perspectiva comparada) de los líderes de Estados Unidos, Brasil, Rusia y China en la 75ª sesión de la Asamblea General de la Organización de Naciones Unidas, en torno al brote epidémico de SARS-COV-2. Se parte del Análisis de Discurso, que aborda el lenguaje como elemento de persuasión y transmisión de preceptos ideológicos y mensajes, a través del cual se analizaron 1017 palabras del discurso de Donald Trump, 2055 de Xi Jinping, 1967 de Vladimir Putin y 2548 de Jair Bolsonaro en una matriz de codificación de acuerdo a los postulados de Bajtín (2011) (estilo, contenido temático y sub-temático) y Van Dijk (2005) (contexto, ideología, acción y poder). Los resultados demuestran que existe una división en dos bandos en el torno a la pandemia. Por un lado, Trump y Bolsonaro se escudan en un discurso populista para señalar a enemigos externos entorno a la situación sanitaria, por otro lado, Jinping y Putin insisten en la necesidad de cooperar y trabajar en conjunto para superar dicha situación. Sin embargo, al profundizar el análisis centrado en la autopercepción se evidencian grandes diferencias: Trump se presenta como defensor de la paz a través de la fuerza, invita a adoptar el nacionalismo y responsabiliza a China del alcance del virus; Jinping defiende el multilateralismo y el modelo de desarrollo pacífico de China, a la par que rechaza el unilateralismo; Bolsonaro se presenta como responsable de la seguridad alimentaria de 1/6 de la población mundial y aunque defiende el multilateralismo, pide que se respete su soberanía sobre la Amazonía brasileña; y Putin recalca la necesidad de nuevos enfoques de multilateralismo y cooperación para lograr nuevas formas de desarrollo e integración.
La inteligencia artificial contra la desinformación: una visión desde la comunicación política
Authors: López-López Paulo Carlos , Díez Nieves Lagares , Puentes-Rivera Iván
Published: March 2022

La comunicación política se reinventa con conceptos tales como la comunicación política algorítmica, fruto de la intersección entre la computación científica y las ciencias sociales, caracterizada por la microsegmentación, por los diagnósticos personalizados, por la generación automatizada de contenidos o por el hecho de que se desdibujan los límites entre lo qué es y lo qué no es ficción. Su investigación como disciplina general, y la desinformación y las notiticas falsas como fenómeno particular, pasa irremediablemente por introducir en la ecuación a la Inteligencia Artificial y su uso por partes de partidos políticos, medios de comunicación y ciudadanía. Unos partidos políticos que sustentarán una democracia algorítmica con grandes efectos sobre las formas de informarse y de participar en un espacio público cada vez más ensanchado; unos medios de comunicación que deben garantizar la autenticidad y trazabilidad de las noticias como mejor barrera ante la desinformación y una ciudadanía que, se observa, empieza a generar ciertas resistencias y mecanismos colectivos de autoverificación a través de sus comunidades digitales.
Study on the relationship between traffic dominance and land use efficiency in Shanghai
Authors:   KANG Chenyuan1*, ZHOU wenqiang2
Published: March 2022

Transportation infrastructure promotes the interconnection of production factors between regions and enhances the efficiency of land use, while land use patterns also have an impact on transportation development patterns and mixes. Although the development of different regions within megacities tends to be integrated, different transportation mixes and land inputs still bring differentiated dynamics to the development of the blocks. In order to explore the relationship between regional traffic conditions and land use efficiency, this paper investigates the traffic development conditions and land use efficiency of each district in Shanghai by using the traffic dominance degree model and the three-stage Super-SBM model, and explores the relevant role relationship between them by using the coupled coordination degree model. The results show that: (1) the central city has the highest traffic dominance, and the suburban areas, especially the distant suburban areas, have low traffic dominance; (2) the land use efficiency of the eastern area of Shanghai is significantly higher than that of the western area, and the land use efficiency of the southern area is higher than that of the northern area; (3) in terms of coupling coordination, the traffic development and land use efficiency of most districts are coordinated, but the degree of coordination varies greatly, with Huangpu District, Yangpu District, Pudong New Area, and Hongqiao District. Yangpu District, Pudong New Area and Hongkou District are at a high level of coordinated development, Chongming District and Changning District are at an uncoordinated development, and the rest of the districts are at a medium level of coordinated development.

The decline of ticket prices to reasonable levels, the increase of airports and the change in the perception of geographical distance have also increased interest in the airline passenger transportation sector. Therefore, it’s important to determine the attitudes and behaviors of passengers as consumers for all segments of the sector. In this study, the effect of social media on consumer behavior and attitudes of passengers in air passenger transportation, whose role in consumer behavior has been shown by different studies in recent years, has been examined with an experimental study. The findings of the study show that there are significant differences in consumer attitudes and behaviors of those who are exposed to social media content compared to those who are not. Also, attitudes and perceptions of the consumers may change according to gender and age. It’s hoped that the results will contribute to marketing practitioners in the industry and expand the social media literature.

Analytical expressions for the steady-state solutions of modified Stokes’ second problem of a class of incompressible Maxwell fluids with power-law dependence of viscosity on the pressure are determined when the gravity effects are considered. Fluid motion is generated by a flat plate that oscillates in its plane. We discuss similar solutions for the simple Couette flow of the same fluids. Obtained results can be used by the experimentalists who want to know the required time to reach the steady or permanent state. Furthermore, we discuss the accuracy of results by graphical comparisons between the solutions corresponding to the motion due to cosine oscillations of the plate and simple Couette flow. Similar solutions for incompressible Newtonian fluids with power-law dependence of viscosity on the pressure performing the same motions and some known solutions from the literature are obtained as limiting cases of the present results. The influence of pertinent parameters on fluid motion is graphically underlined and discussed.
On the inverse sum indeg index (\(ISI\)), spectral radius of \(ISI\) matrix and \(ISI\) energy

Published: March 2022

The inverse sum indeg index \(ISI(G)\) of a graph is equal to the sum over all edges \(uv\in E(G)\) of weights \(\frac{d_{u}d_{v}}{d_{u}+d_{v}}\). This paper presents the relation between the inverse sum indeg index and the chromatic number. The bounds for the spectral radius of the inverse sum indeg matrix and the inverse sum indeg energy are obtained. Additionally, the Nordhaus-Gaddum-type results for the inverse sum indeg index, the inverse sum indeg energy and the spectral radius of the inverse sum index matrix are given.
From quasilinear structures to population dynamics: Global stability analysis of an uncertain nonlinear delay system with interval approach
Authors:   Inönü University, Department of Mathematics, Malatya, 44280, Turkey, Çakan Sümeyye
Published: March 2022

In this paper, we analyze a new continuous-time epidemic model including nonlinear delay differential equations by using parameters and functions selected from a class of intervals whose algebraic basis is based on quasilinear spaces. The main idea in the model’s generic structure is based on uncertainties in the values of parameters and functions forming the model. Therefore, using an interval coefficient approach rather than the exact value of parameters and functions that define transmissions between the compartments in the population dynamics will better represent the reality. Furthermore, preferring such an approach provides more realistic scenarios for temporal and stability dynamics of a population exposed to a disease. In this study, the quasilinear space is defined to explain the mathematical background of the interval approach in the fictional chain of the model. Next, descriptions belonging to the introduced model are included. After this compartmental system is presented as two systems formed by the lower and upper endpoints of the intervals determining parameters and functions, local and global dynamics related to stabilities of the models are analyzed separately for each. Then, using some interval analysis and functional analysis methods, these results are combined, and a conclusion about the stability of the proposed epidemic model has been reached. Alongside, the performance of the proposed approach is demonstrated by a visual simulation.

Published: March 2022

Stature is an essential anatomical parameter for creating the biological profile of persons in forensic analysis. The aim of the study was to establish regression formulae for the estimation of stature from plain radiographs of humerus. A total of 90 subjects (49 males and 41 Females) were recruited randomly for the study at the Lulu-Briggs Health centre, University of Port Harcourt. An x-ray of the humerus was taken after measuring the heights of volunteers. The films obtained were later fixed to an x-ray illuminator where the humeral length (HML) was measured using a lead pencil and ruler. Statistical analysis was done for all parameters (stature and humeral length) using SPSS. Pearson’s co-efficient of stature versus HML were 0.66 for males and 0.50 for females. The regression equation for estimation of stature were 2.45 (HML) + 89.20 for males and 2.16 (HML) + 97.17 for females. Standard error for regression formula derived was observed to be 0.41cm in males and 0.59 cm in females which indicates a high level of reliability on the formula and proves further to show that the humerus is a good predictor of stature. In conclusion, the use of x-ray is a reliable procedure and a practical approach in stature estimation and the humerus is a good predictor of stature in the Nigerian population.

Published: March 2022

Meat eating aids in the absorption of proteins and vital amino acids, as well as vitamins and minerals such as vitamin B, vitamin A, zinc, and iron, all of which are required for a balanced diet. This evaluation looked into the many types of hydrocolloids and whether they may be used as a new, safe natural meat preservative. Natural, semi-synthetic, and synthetic hydrocolloids are classified according to their origin. Hydrophilic polymers generated from natural sources such as plants, animals, microbes, and seaweeds are known as natural hydrocolloids. Semi-synthetic hydrocolloids, on the other hand, are modifications of naturally formed hydrocolloids, whereas synthetic hydrocolloids are chemically manufactured from petroleum-derived base materials to produce a product with a structure comparable to natural polysaccharides. In recent years, natural hydrocolloids have been widely preferred in the food industry for improving the stability, functionality, quality, safety, nutritional and health benefits of various food products over semi-synthetic and synthetic hydrocolloids due to: Extracted from renewable sources, readily available and easy to handle, Biocompatible, Non-toxic, Capable of physical and chemical modification, Eco-friendly and cost-effective, More acceptance by the general public. According to the study, the growth is a direct outcome of the increased use of hydrocolloids. In the food industry, functional qualities are still the most common application of hydrocolloids.
Pemanfaatan Lahan Pekarangan Daerah Perkotaan Melalui Pemberdayaan Masyarakat dan Teknologi Hidroponik Skala Kecil

Published: March 2022

Teknik hidroponik merupakan teknik budidaya tanaman tanpa menggunakan media tanah. Budidaya tanaman ini tidak memerlukan lahan yang luas, bisa juga dilakukan di pekarangan atau di teras rumah sehingga sistem hidroponik bisa digunakan untuk mengatasi masalah kekurangan lahan. Seperti halnya perumahan-perumahan di perkotaan pada umumnya, rumah-rumah di perumahan Sapphire Regency mempunyai lahan pekarangan yang relatif sempit dan terbatas. Lahan pekarangan yang sempit menjadikan pemanfaatannya kurang maksimal. Warga perumahan juga pada umumnya belum memiliki pengetahuan tentang cara pembuatan dan instalasi hidroponik untuk tanaman sayuran. Dari permasalahan mitra tersebut, solusi yang ditawarkan dari kegiatan pengabdian ini adalah kegiatan alih teknologi tentang pemanfaatan lahan pekarangan dan pembuatan instalasi hidroponik skala kecil (Small-Scale Hydroponics Farming System). Hasil kegiatan pengabdian menunjukkan bahwa minat masyarakat sasaran sangat tinggi terhadap budidaya tanaman secara hidroponik dengan memanfaatkan halaman rumah daerah perkotaan yang tidak terlalu luas, serta pemahaman masyarakat terhadap budidaya tanaman secara hidroponik meningkat dengan adanya kegiatan penyuluhan dan alih teknologi.
