Published: July 2021

La gestión del recurso hídrico es prioritaria en la agenda de la Organización de las Naciones Unidas. Tres vectores son esenciales, cantidad, calidad y escenarios del cambio climático en el recurso hídrico. En la región centro de Tamaulipas, México, destaca la red fluvial de la cuenca del río Soto la Marina, con los ríos Corona, Purificación y Pilón, como principales tributarios. En esta región existen importantes volúmenes de aguas residuales y otros vertimientos que ponen en riesgo las condiciones del sistema hídrico, particularmente de la presa Vicente Guerrero. El objetivo de este trabajo fue desarrollar un modelo hidrológico de disponibilidad y calidad del agua de la cuenca del río Soto la Marina (CRSLM) que considere el cambio climático mediante la regionalización de dos modelos de circulación global, los cuales son los más cercanos a la latitud en que se encuentra la cuenca (GFDL-CM3 y HAGDGEM2-ES), usando dos vías de concentración representativas (RCP): 4.5 y 8.5 con proyección al año 2100, con el propósito de analizar el comportamiento de la cuenca, a efecto de simular la vulnerabilidad hídrica. Se evaluó la calidad del sistema espacio-temporal: avenidas y sequías, mediante la determinación de demanda bioquímica de oxígeno, demanda química de oxígeno y oxígeno disuelto, además de temperatura, en 15 sitios de la cuenca del río Soto la Marina, con modelado del abatimiento del oxígeno disuelto. Se elaboraron vectores de hidrología, monitoreo y calidad del agua. Las concentraciones de los contaminantes valorados presentaron un incremento en la presa Vicente Guerrero, aunque su comportamiento estacional fue más sensible en estiaje que en avenidas. En las simulaciones con el modelo construido WEAP con escenarios de cambio climático se predijeron resultados más conservadores en período de estiaje que en época de avenidas, siendo el RCP 4.5 W/m2 para el modelo el GFDL-CM3 la proyección más adversa.

Published: July 2021

Las experiencias escolares de estudiantes con discapacidad son un recurso efectivo de información para que los sistemas educativos se vuelvan más inclusivos y equitativos. El objetivo del presente trabajo fue detectar soportes escolares, barreras y necesidades de inclusión de estudiantes con discapacidad en la Universidad Autónoma de Tamaulipas, campus Victoria, para proponer un modelo educativo más inclusivo y equitativo, basado en sus experiencias. El diseño de la investigación incluyó una modalidad cualitativa basada en estudios de caso con una perspectiva explicativa a través de la teoría fundamentada. Se entrevistó a profundidad a 10 estudiantes con discapacidad y 10 docentes que impartieron clase a estudiantes con esta condición. Los resultados reflejaron la presencia de soportes escolares en la actitud personal y social, en las becas, en apoyo entre docentes, adaptaciones curriculares y estrategias de aprendizaje. También se encontraron barreras escolares en la accesibilidad física y la estructura académica, así como actitud discriminatoria, desconocimiento de tipos de discapacidades y su tratamiento, y la ausencia de fortalecimiento institucional para la inclusión. Además, evidenciaron que la Universidad está en el camino hacia la inclusión, pero requiere afianzar acciones para el tránsito, permanencia y logro educativo del estudiantado con discapacidad. El modelo de inclusión y equidad institucional precisa reforzar al menos 8 elementos para mejorar su eficiencia: claridad en el concepto, cultura y espacios inclusivos, currículo flexible, formación de docentes, experiencias compartidas entre docentes y mejores prácticas, supervisión en la participación, evaluación del logro educativo y vinculación con el sector laboral. Lo anterior permitirá valorar la diversidad de necesidades de estudiantes universitarios con discapacidad, para otorgarles un fortalecimiento institucional que les brinde una mayor inclusión educativa.
Metabarcoding de DNA ambiental: un enfoque para el seguimiento de la biodiversidad
Authors: Padilla-García Cinthia Yedith , Camacho-Sánchez Fátima Yedith , Reyes-López Miguel Ángel
Published: July 2021

El término ácido desoxirribonucleico ambiental o DNA ambiental (eDNA) se acuñó para definir al ácido desoxirribonucleico (DNA) que se puede recuperar o detectar del ambiente (por ejemplo: suelo, aire o agua) sin necesidad de que el espécimen esté físicamente presente. El objetivo del presente trabajo fue analizar y ejemplificar los usos, aplicaciones y potencial del eDNA. El estudio del eDNA es utilizado para la evaluación de especies, que va desde la reconstrucción histórica de sus comunidades, la restauración del ecosistema, hasta la salud humana, lo que lo convierte en una herramienta versátil e importante para el futuro en investigación, permitiendo estudios de conservación, taxonómicos o de reconstrucción filogenéticos. Para lograr esto, se usa el procedimiento de metabarcoding, el cual se basa en obtener DNA de cualquier origen (en este caso eDNA), en ausencia física o no del organismo, con apoyo de la reacción en cadena de la polimerasa (PCR), para finalmente, secuenciarlos y obtener códigos de barras. Los estudios de eDNA probablemente se constituirán como un enfoque esencial para diversas tareas científicas no solo en el seguimiento de la biodiversidad, sino en el análisis de la salud humana o la generación de códigos de barras de DNA.

Published: July 2021

Las ventajas de incorporar abonos orgánicos (AO) disminuyen cuando sus propiedades físicas, químicas y microbiológicas no son las adecuadas. El objetivo de la presente investigación fue caracterizar abonos orgánicos destinados a suelos florícolas y analizar las repercusiones de su aplicación. Se determinaron las propiedades de 10 AO: potencial de hidrógeno (pH), conductividad eléctrica (CE), materia orgánica (MO), contenido de nitrógeno, fósforo, potasio y nitratos. Se utilizó un diseño completo al azar y análisis de varianza (P ≤ 0.05) para evaluar el índice germinativo (IG) en semillas de rábano y maíz, con lixiviados de AO al 5 %, así como la actividad microbiana de tres AO incorporados al suelo en incubaciones aerobias. El pH promedio fue de 8.2 ± 0.81, y el intervalo de la CE en AO fue de 0.15 dS/m a 6.7 dS/m, mientras que el de la MO fue de 28.8 % a 80 %. El IG fue diferente estadísticamente (P < 0.05) en cada especie de semilla. Asimismo, la incorporación de AO incrementó significativamente (P < 0.05) la actividad microbiana del suelo. Se concluye que la heterogeneidad de la materia prima genera una gran variabilidad en las características de los AO, sin embargo, en todos los casos, su aplicación mejoró las propiedades de los suelos florícolas.

Published: July 2021

Los hongos micorrízicos arbusculares (HMA) son importantes para el desarrollo y supervivencia de las plantas. Esto ha motivado el análisis del uso de algunas especies de HMA de uso comercial como biofertilizantes de cultivos a nivel nacional. En Tamaulipas, el conocimiento acerca de la diversidad de HMA es escaso. El objetivo del presente trabajo fue determinar la presencia e identidad taxonómica de hongos micorrízicos arbusculares asociados a la familia Euphorbiaceae (sensu lato) en el Área Natural Protegida Altas Cumbres. Las esporas fueron obtenidas a través de propágulos extraídos de plantas trampa de diferentes especies, cultivadas en suelo y raíces de la zona de estudio. El estatus micorrízico se determinó mediante la técnica de tinción de Phillips y Hayman y la identificación de HMA, a través de la extracción de esporas por el método de tamizado húmedo con centrifugación con sacarosa, y su caracterización morfológica. Todas las raíces mostraron estructuras típicas de los HMA, evidenciando la presencia de esta asociación en los 74 taxones de euforbiáceas. Se registró una riqueza de 9 especies de HMA ubicadas dentro de 6 géneros, 4 familias y 3 órdenes, siendo Glomus (Familia Glomeraceae) el género con mayor riqueza específica. Se detectó la presencia de los géneros Entrophospora, Funneliformis y Rhizophagus por primera vez en Tamaulipas. Los resultados denotan lo ampliamente distribuidos que se encuentran los HMA en las plantas de la familia Euphorbiaceae en el Área Natural Protegida Altas Cumbres y la necesidad e importancia de continuar con investigaciones sobre las micorrizas arbusculares.

O sistema de Economia Circular e a Agenda 2030: análise da evolução em Portugal
Authors: Pereira Raquel
Published: July 2021

A crescente consciencialização da sociedade para os problemas ambientais, aquecimento global, consumo massivo de recursos e aumento das desigualdades, tem exercido uma forte pressão sobre os países e organizações, estando na base da Agenda Global 2030, adotada pelas Nações Unidas, e na definição dos Objetivos de Desenvolvimento Sustentável. Neste contexto, a Economia Circular é considerada uma abordagem fundamental para alcançar alguns desses objetivos uma vez que procura a implementação de processos de produção tecnologicamente inovadores e eficientes, que se traduzam na redução do consumo e extração de recursos finitos, na reconversão e reutilização dos resíduos e na utilização de “energias limpas”. Este trabalho pretende discutir a relação entre a Economia Circular e o Desenvolvimento Sustentável e fazer uma análise comparativa, no contexto europeu, à evolução de Portugal para alguns dos indicadores específicos estabelecidos na Agenda 2030. A análise indica que, apesar da evolução positiva, em vários dos indicadores analisados, o desempenho português, em termos globais, está abaixo do desempenho médio europeu. Adicionalmente, para alguns indicadores a evolução ocorreu em sentido contrário ao desejável. Apesar de termos uma sociedade e cidadãos cada vez mais conscientes e atentos a produtos, processos e entidades “sustentáveis”, há ainda um longo caminho a percorrer para que os pressupostos da Economia Circular e do Desenvolvimento Sustentável sejam plenamente reconhecidos e aplicados.

Produksi Bersih Pengolahan Limbah Cair Menggunakan Decanter pada PT Aetra Air Jakarta
Authors: Sukwika Tatan , Muhammad Said Azmi
Published: July 2021

ABSTRACT
Clean water process production by PT Aetra Air Jakarta (AAJ) emits a lot of wastewater. All this time, a sludge drying bed is used for its production activities, where the sludge produced is not proportional to the area and length of drying time, so the unsatisfied sludge is eventually dumped into the water body. In line with the need to improve the quality of operational activities, clean water service providers are trying to create zero waste. They are environmentally friendly through the use of a decanter. The research objective was to determine the amount of sludge treated in the wastewater treatment process and measure water removal efficiency in sludge using a decanter. Methods of data collection through observation and testing of wastewater treatment using a decanter. The decanter treatment process starts from taking the sludge sample before it is processed; the sludge treatment process begins entering the decanter until the sludge is finished processing. The results showed that the average volume of sludge was 24.84 m3, and the water removal efficiency was between 89–91%. The conclusion is that the set inflow rate is directly proportional to TSS while the efficiency of TSS water removal in the sludge is smaller so that the use of a decanter is greater. It recommended that the residual processing sludge be used as raw material for fertilizer production. The Pb and Zn content in the sludge does not exceed the quality standard.
Keywords: decanter, clean production, TSS, sludge volume
 
ABSTRAK
Air bersih yang diproduksi oleh PT Aetra Air Jakarta (AAJ) mengeluarkan banyak limbah cair. Selama ini, kegiatan produksinya digunakan sludge drying bed, dimana lumpur yang dihasilkan tidak sebanding dengan luas dan lamanya waktu pengeringan, sehingga lumpur yang tidak tertampung akhirnya terbuang ke badan air. Seiring kebutuhan perbaikan kualitas kegiatan operasional, penyedia layanan air bersih berupaya menciptakan zero waste dan ramah lingkungan melalui penggunaan decanter. Tujuan penelitian menentukan jumlah lumpur yang diolah pada proses pengolahan limbah cair dan mengukur efisiensi penyisihan air pada limbah lumpur menggunakan alat decanter. Metode pengumpulan data melalui pengamatan dan pengujian pengolahan limbah cair menggunakan decanter. Proses pengolahan decanter dimulai dari pengambilan sampel lumpur sebelum diolah, proses pengolahan lumpur dari awal masuk ke decanter sampai lumpur selesai diolah. Hasil penelitian menunjukkan rata-rata volume lumpur sebesar 24,84 m3, dan efisiensi penyisihan air antara 89–91%. Kesimpulannya adalah set inflow rate berbanding lurus dengan TSS sedangkan efisiensi penyisihan air TSS pada limbah lumpur semakin kecil sehingga penggunaan decanter menjadi lebih besar. Direkomendasikan agar lumpur sisa pengolahan dimanfaatkan sebagai bahan baku untuk pembuatan pupuk dengan syarat kandungan Pb dan Zn dalam lumpur tidak melebihi baku mutu.

Cockatoo (Cacatua sp.) is one of birds that is widely distributed in Indonesia and often kept as pet, thus threatening the Cacatua population in the wild. Environmental condition may affect the behavior of Cockatoo. Some unnatural behavior may arise due to living in the captive. Different cage conditions may result in different behavior performance in Cockatoo. Research on daily behavior at animal rescue sites at ASTI Bogor has never been conducted. This study aimed to analyze natural and stereotype behavior of Cacatua sp. at animal rescue center due to foreclosure, and analyze the relationship between cage condition and environmental factors. This study used focal instantaneous sampling, using eight individuals Cacatua sp. Cacatua sp. in ASTI performed natural behavior more than unnatural behavior, therefore ASTI can be a good place for animal rescue. The dominant natural behaviors were Resting (Re), Preening (Pr), Feeding (Fe), Locomotion (Lo), and Fighting (Fg), while unnatural behaviors were play, bite, abnormal vocalization, feather picking and aggressive. There are no difference in behavior between male and female, and also behavior in the morning and afternoon (p>0.05), but cage condition had a significant effect to daily behavior of Cacatua sp. (<0.05).

The main purpose of this article is to present the most important conditions and variables characterizing the role of the Middle East in Yugoslavia’s foreign policy strategy in the 1970s, based on available literature and documentation. I also intend to analyze the conditions that contributed to intensifying Yugoslavia’s position in the region and led to a decrease in Yugoslavia’s importance in the Middle East in the second half of the decade. Firstly, I will describe Yugoslavia’s relations with the countries of the Middle East in 1970–1973, especially with Egypt, where Gamal Abdel Nasser, after his death, was succeeded by the country’s Vice President, Anwar Al-Sadat. It will also be important to shed light on the Yugoslav Government’s stance regarding the Middle East conflict from the point of view of the situation in Europe. Next, I will present the significance of the Yom Kippur War for Yugoslavia’s foreign policy and its implications for Belgrade’s relations with Cairo and Tel-Aviv. Moreover, it will be extremely important to explain why Yugoslavia’s importance in the Middle East gradually diminished as of the middle of the decade. In addition, I will address the issue of Yugoslav President Josip Broz-Tito’s position toward the Islamic Revolution in Iran and the fading of Yugoslavia’s interest in the region following Tito’s death and the Soviet invasion of Afghanistan. In the summary, I want to note that the period under analysis in Yugoslav-Middle Eastern relations was decisive for the country’s foreign policy and its internal situation, as Yugoslavia never again played a significant role in the Arab world.

Major changes in the position of Kosovo and Metohija’s autonomy in the late 1960s affected the province’s relations with Albania. In 1967, the Yugoslav State Secretariat of Foreign Affairs and the Yugoslav Federal Executive Council began to encourage cultural and economic ties between Kosovo and Metohija and Albania, justifying this as a strategy for the normalization of relations between Yugoslavia and Albania. Following the joint commemorations of the anniversary of Skanderbeg’s death in Priština and Tirana, an agreement was reached on the use of textbooks from Albania in the Kosovo and Metohija school system. The two sides organized mutual visits of folklore and art groups, as well as friendly matches of soccer teams. Kosovo companies were allowed small border traffic with Albania without any prior interstate agreements between Belgrade and Tirana. Constitutional changes in Serbia in 1969 enabled the expansion of economic and cultural cooperation between Kosovo and Albania. The University of Priština and the University of Tirana signed an agreement to hire professors from Tirana as lecturers at Priština faculties. In 1971, scientists from Tirana participated in the work of the Kosovo Archives, the Provincial Library, and the Priština Museum, while 41 Albanian professors gave lectures at the University of Priština. Reports by Albanian lecturers from Kosovo enabled the Albanian state leadership to be acquainted in detail with the political situation in Yugoslavia.

Abstract – Broiler chickens or broiler chickens are one of the popular sources of nutrition in Indonesia. The production of broilers reaches 3.15 billion heads, with the most production center on Java’s island. The Covid-19 disaster that hit Indonesia caused broilers’ production to decrease due to the government’s social restrictions. To maximize production and reduce production efficiency, artificial Intelligent application innovations are carried out for temperature, humidity, and gas control in broiler chicken coops. Artificial Intelligent methods of developing machines can think like humans to help control and make decisions. This artificial Intelligent model uses a fuzzy logic  Pulse Width Modulator (PWM)model. The device used for control utilizes Internet of Things technology with a microcontroller as its primary device and sensor as an environmental data reader. The microcontroller used is ESP32 which has been embedded with Wifi to facilitate the transmission of data to the server. To read the sensors’ environmental conditions used by temperature sensors, humidity uses DHT11 and ammonia gas using MQ2. Environment data is sent to the server, which is useful for the user monitoring the cage environment’s condition remotely and, if needed, can be controlled by using the application interface. In this research, the process of system development using waterfall method, namely needs analysis, design, implementation and testing. The system’s application results were tested using two models, namely, trying the sensor reading value compared to the weight on the hygrometer and observation of the reaction of chickens in the cage. The test results obtained the difference in value between the sensor and hygrometer can be tolerated and the chicken reaction following the system’s cooling status.

Coronavirus disease (Covid-19) or commonly called coronavirus. This virus spreads very quickly and even almost infects the whole world, including Indonesia. A large number of cases and the rapid spread of this virus make people worry and even fear the increasing spread of the Covid-19 virus. Information about this virus has also been spread on various social media, one of which is Twitter. Various public opinions regarding the Covid-19 virus are also widely expressed on Twitter. Opinions on a tweet contain positive or negative sentiments. Sentiments of sentiment contained in a tweet can be used as material for consideration and evaluation for the government in dealing with the Covid-19 virus. Based on these problems, a sentiment analysis classification is needed to find out public opinion on the Covid-19 virus. This research uses Artificial Neural Network (ANN) algorithm with the Backpropagation method. The results of this test get 88.62% accuracy, 91.5% precision, and 95.73% recall. The results obtained show that the ANN model is quite good for classifying text mining.

School magazines are a medium for students to practice and develop their journalistic potential. A student must have qualified journalistic knowledge to produce good writing in a magazine. For this reason, training and assistance in magazine writing are necessary so that school magazines continue to exist and are of higher quality. One school that has a school magazine is MA Al-Muayyad Surakarta. Journalism training is essential at this school because many students have not developed their writings properly. The methods used in this training are interviews, presentations, discussions, and article writing training. This training was held in April 2018. This training activity provides good benefits, especially for the training participants, because before the training was held, most of the magazine's contents took sources from the internet. However, after the training, the students' writing became original, the language used got better, and the rubric content more diverse.
