Authors: Aggarwal Pragya , Singh Sushila , Sangwan Seema , Moond Monika
Published: September 2023

Studying the physiological effects of the three extraction solvents (water, methanol, and acetone) on the antioxidant activity of Khejri stem bark extract was the goal of this research (Prosopis cineraria L.). Khejri stem bark is characterized by their chemical and mineral composition. Higher phenol content, total flavonoid and antioxidant activity could be obtained using acetone as a solvent, followed by methanol and aqueous solution. The tested plant material contained a significant amount of total phenols (2.31 ± 0.13 mg GAE/g) and total flavonoids (0.88 ± 0.14 mg EC/g) in the acetone extract. With an increase in dynamically variable concentration levels, Khejri stem bark extract’s ability to scavenge DPPH free radicals rises. The total antioxidant capacity of the acetone extract was the greatest (1.180.89 mg AAE/g), and the acetone extract demonstrated the strongest free radical scavenging activity of DPPH and IC50 value was 179.44 mg/ml.

A field experiment was conducted to find out effect of salicylic acid (SA), GA3, pinching and their interaction on the growth and flowering attributes of verbena × hybrida. Three concentration each of GA3 (100,150 and 200 ppm) and SA (100, 150 and 200 ppm) was foliar sprayed at 21 days after transplanting to run-off stage and pinching was done at 40 days with three replications set in Randomized Block Design. Pinching treatment recorded significantly maximum no. of primary branches/plant, stem diameter, fresh weight and dry weight of leaves, fresh leaf biomass, leaf area, flower longevity, fresh weight of flower, no. of spikes/plant and peduncle length. However, no. pinching treatment recorded maximum plant height, early bud initiation and early flowering. Spraying of GA3 100 ppm resulted in early bud initiation. GA3 150 ppm recorded fresh weight of leaves, fresh leaf biomass and bud cluster diameter. However, maximum plant height, leaf area, no. of spikes/plant and peduncle length was observed with GA3 at 200 ppm. Among various doses of salicylic acid, SA 100 ppm recorded maximum stem diameter. Early flowering, maximum fresh and dry weight of flower was seen with SA 150 ppm. SA 200 ppm resulted in maximum no. of primary branches/plant and flower diameter. Significant effect of interaction between pinching and plant growth chemicals (GA3 and SA) was observed in most of the growth and flowering attributes.

Dye-sensitized solar cell (DSSC) is a class of third generation solar cells that are formed by placing a semiconductor between a photosensitized anode and an electrolyte, which allows the light to pass through the cell. Synthetic dyes, usually ruthenium-based and commonly used in DSSCs, are environmentally toxic and expensive than natural dyes. The aim of the study was to investigate native and cheap sources of natural dyes as photosensitizers for DSSCs using tropical plants. Dyes from four different local plant sources were successfully extracted, prepared, and characterized and were used as alternative, non-toxic, natural photosensitizers. The visible spectra of the extracts with peaks between 430-440 nm suggest that they are dominated by chlorophyll a (430-662 nm) and chlorophyll b (453-642 nm). When observed under ambient conditions, the fabricated DSSCs demonstrated high outputs for OCVmax wherein 433, 397, 311, and 203 mV were obtained using dye-sensitizers from dried talisay leaves (Terminalla catappa), spent coffee grounds (Coffea spp.), fresh talisay leaves, and alugbati fruit (Basella alba), respectively. The observed open circuit potentials were comparable with other reported DSSCs. The output current, fill factor, and cell efficiency can be improved by co-sensitization and increasing the lightscattering capability, among other methods of constructing the DSSCs. Generally, with the limited impacts to the environment and cheap production cost, this research has opened opportunities for application of natural dye from local sources for renewable energy technologies.

Rainfed lowland rice ecosystem occupies ~30% (~1.4 M ha) of the total rice production area in the Philippines. In this ecosystem, other rice varieties or ecotypes not bred for this ecosystem are also cultivated and may suffer from severe yield loss when drought occurs. Under such stress condition, paclobutrazol (PBZ) was reported to improve physiological processes and enhance yield of tillering crops by increasing the number of tillers and panicles. This study aimed to determine the effects of PBZ on the growth and yield response of different rice ecotypes under rainfed condition. The experiment was laid out in split-plot design with PBZ concentrations (0, 250, 500 ppm) as main plot applied at 14 days after transplanting. Rice ecotypes, namely rainfed lowland (PSB Rc14), irrigated lowland (NSIC Rc222), upland-special quality (Dinorado) and lowland-special quality (NSIC Rc216) as subplot, were arranged in randomized complete block design with three replications. Results showed that PBZ temporarily suppressed plant height of different rice ecotypes as they were able to recover resulting in increased plant height at maturity. PBZ also improved the tillering and tiller’s ability to produce panicles resulting in a higher number of panicles at maturity. Other yield components, namely panicle length, number of spikelets and filled spikelets per panicle, especially percent filled grains, were also improved. Grain yield likewise increased with different optimum PBZ concentrations for each rice ecotype. A lower concentration (250 ppm) gave the highest grain yield for lowland rice ecotype while higher concentration (500 ppm) for special-quality rice.

The use and reuse function of chalkboard produces chalk dust particles in the classroom entering into the classroom occupants’ respiratory system through their mouths and nasopharyngeal regions while talking or breathing. The potential impact of dust particles of the respiratory system includes airflow resistance, lung volumes impairment and lung damage. This study measured the expired volume of air from the lungs during a guided maximal expiration to determine the effect of chalk dust particles on the ultimate lung function in the classroom. The sociodemographic characteristics of the participants were assessed using oral interview while the assessment of the anthropometric data and the participants’ lung function indices was done through the use of a stadiometer and digital spirometer, respectively. This study employed a quasiexperimental research design. It involved the exposed (n = 120) and control (n = 120) groups selected from classrooms where chalkboards and marker boards were used, respectively. The results revealed that among the lung functions indices investigated, there were statistical significant differences between the exposed and the control groups in FEV1 (%) (0.002), PEFR (L/s) (0.000), FEF25 (L/s) (0.000) FEF75 (L/s) (0.000), FEF25-75 (L/s) (0.000), FEV1 (%) (0.002) but no significant differences in FEV1 (0.135), FVC (0.493) and FVC (L) (0.506). Therefore, chalk dust particles from chalkboard usage had a negative effect on the respiratory function (lung function indices) in the classrooms.

The three-month-old native species of Anonang (Cordia dichotoma Forst) were planted in potting bags in a nursery to determine its growth progress as influenced by different soil enhancers. The study was laid out in a completely randomized design with five treatments and four replications per treatment. Each treatment had 16 plants having a total of 80 plants. Growth parameters used were percent survival, height, stem diameter, leaf number, leaf area, total fresh weight, and total plant biomass. Results and analyses revealed that among treatments, the most suited one was the decomposed rice hay, which obtained the highest survival rate (93.75%), tallest height (39.48 cm), biggest stem diameter (0.61 mm), highest number of leaves (14 counts), largest leaf area (46.62 cm2 ), and heaviest shoot (10.94 g), root (1.79 g) and total plant (12.73 g) biomass. Hence, it is recommended to establish tree nurseries for raising Anonang seedlings. Since the duration of the study was only six months, future work should focus on testing the survival of Anonang in the field with a prolonged time of at least one year to achieve more valuable results.

The traditional production of kefir uses raw milk as a fermentation substrate which is not acceptable due to food safety issues. However, kefir grains were reported to have antimicrobial properties. Hence, this study determined if kefir grains inhibited certain spoilage and pathogenic microorganisms by comparing the chemical and microbiological properties of the initial substrates: raw milk (RM) and pasteurized milk (PM) to the final products: raw milk kefir (RMK) and pasteurized milk kefir (PMK). Both final products had a significant decrease in fat, moisture, and pH, and a significant increase in protein, total solids, and titratable acidity than RM and PM, respectively. Total solids, titratable acidity, pH, total alcohol, and ethanol were significantly higher in PMK than RMK. RMK had a significantly lower coliform count than RM while both RMK and PMK had significantly higher lactic acid bacteria, yeast and mold count than RM and PM, respectively. Kefir grains’ microbial inhibiting activity was examined if plates were positive or negative against spoilage and pathogenic microorganisms. Escherichia coli-positive plates in Levine’s eosin methylene blue agar decreased in RMK. Salmonella spp.-positive plates in bismuth sulphite agar (BSA), Hektoen enteric agar, and xylose lysine deoxycholate agar decreased in RMK and PMK except for RMK in BSA. Staphylococcus aureus-positive plates in Baird-Parker agar decreased in RMK. RMK and PMK attained the kefir’s standard values for the chemical composition, lactic acid bacteria, yeast and mold count. Nonetheless, the mere presence of spoilage and pathogenic microorganisms in the final products made it unsafe for consumption.

Increasing concern on the efficacy of antimicrobials has spurred a demand for research on natural-based alternatives. This study assessed the efficacy of Carica papaya, Chromolaena odorata and Piper betle leaves extracts against mites (Sarcoptes scabiei var. canis). Efficacy was defined as the percent reduction in the number of live mites after 6 h of exposure to the treatments. The study utilized 100% fresh crude extract (FCE), 50% fresh crude extract in water (FCW), 50% ethanolic extract reconstituted in 60% ethanol (EEE) and 50% ethanolic extract reconstituted in distilled water (EEW) of the plants for the in vitro assay against S. scabiei var. canis. All plants exhibited varying acaricidal efficacy at different extraction procedures. Their FCW, EEE and EEW showed excellent acaricidal efficacy with P. betle showing maximum efficacy within 30 min of exposure. Thus, the three plants are potential sources of natural-based products for the treatment of canine sarcoptic mange. Further pharmacological and in vivo studies are recommended to validate their acaricidal efficacy.

The restaurant industry has grown over the years along with the modernization of technology. Like any other area of this industry, the menu presentation also demands improvement. Possessing smartphones proved to be a necessity nowadays and regular restaurant customers with their phones bring an opportunity to materialize the concept. The idea of accessing the restaurant menu through smartphones is new to a restaurant in Oriental Mindoro, Philippines. Hence, the proponents were motivated to develop the eCarte – an interactive restaurant menu with feedback collection. The development of this system can improve the customer's experience which would be beneficial to the restaurant. Proponents used incremental development as a software development method to come up with an efficient system. The developed system is userfriendly and interactive. The customers will be able to see the actual picture of the dish with a short description, and other customers’ reviews. Selected Information Technology Faculty, restaurant owners and customers evaluated the system. The five evaluation criteria used were adapted from ISO 25010 software quality standards. Based on the evaluation result, eCarte is usable and met its expected functions in terms of functional suitability (4.93), performance efficiency (4.88), usability (4.84), security (4.83), and maintainability (4.84). The system is generic, not expensive, easy to maintain and suitable to any smartphone regardless of its operating system which makes it applicable to any local restaurant. For further improvement, the proponent recommends applying an algorithm like the High Adjective Count algorithm and Max Opinion Score algorithm to effectively analyze the customer's feedback.

A common problem in a developing tropical country like the Philippines is the flooding during downpours. One of the causes is the clogging of drainages due to garbage accumulation, which results in overflowing. A countermeasure to minimize this problem is the deployment of an internet of things-based garbage monitoring system. In this system, the ultrasonic sensors were used to provide input data on the level of the garbage in the drainage. These data were then transmitted to the web application for visualization. A message, informing the status of the garbage level in real-time, was sent to the registered user. Also, a strainer was used to serve as a stopper of the accumulated garbage in the drainage. This strainer was set up in the middle of the manhole so that the detected level of garbage and water would be compared. In addition, the ultrasonic sensors were mounted on the top and the back of the strainer to detect the garbage level and serve as a comparative sensor, respectively. Furthermore, to assess the performance of the developed system, several tests were conducted in Cebu City, Philippines. These tests included the short message service delay, internet speed, and the garbage level. The results showed that the developed system can effectively deliver its desired operations. However, since the system is reliant on internet connectivity, it is highly recommended to use such in a 5G network.

The increase in the degree of soil saturation by rainwater infiltration is detrimental to the stability of slopes. For an accurate assessment of the potential triggering of rainfall-induced slope instabilities, the use of analytical assessment methods must be complemented with more precise information regarding the dynamic saturation behavior of the investigated soil. To obtain such soil-specific data, this study conducted a series of laboratory saturation simulations by exposing the variably sloped soil sample to artificial rains of moderate and typhoon-patterned intensities. The recorded data were consolidated to profile the temporal saturation responses of the soil, provide empirical equations for estimation of the normal movement of the infiltration front, and determine the saturation threshold of the tested soil. Based on the results, it was found out that the wettest possible soil state could be attained under partially saturated conditions but only for gentle slopes of up to 20°. The fully saturated zone originated at the bottom as opposed to the wetting front concept. For steeper slopes of 30° and above, surface runoff was more dominant that the infiltrated water could barely increase the soil moisture content at a depth of 0.626 m by less than 5%. High saturation thresholds were observed at the bottom (0.626 m depth) at values ranging from 83.7 to 99.7%.

Renewable energy system development includes necessary and precise planning for identifying the energy potentials involving the selection of sufficient factors, criteria, methods and techniques. Establishing a solar energy system in Cagayan Valley Region is very suggestive; however, scientific reports and literature about it are lacking. This study aimed to determine a suitable location for solar energy system development and potential energy generation in Cagayan province, Philippines. It employed and demonstrated the application and combination of the geographic information system (GIS) and multi-criteria decision-making (MCDM) technique, particularly the analytical hierarchy process (AHP). Three criteria were considered, namely technical aspect (solar insolation), environmental aspect (land use-land cover and protection buffers) and economic aspect (slope, elevation and road proximity). Results showed that only 18.47% (1716.9 km2) of the total land area was suitable for solar photovoltaic system development. With the total suitable area, a solar electricity generation potential of 139.9 TWh/year can be attained even considering the least module efficiency of 10%. This solar energy generation potential is generally higher than that of the household electricity consumption of the Cagayan Valley Region, which could be a great avenue for energy sustainability for the province and the region. With sufficient factors and criteria, the combination of GIS and AHP tool is a great technique in identifying renewable energy projects’ suitability in a certain location.

Published: September 2023

Food security is of global concern, which requires more attention on the identification of alternative sources. To combat and marginally prevent the issue, human edible grains can be excluded from the livestock feed. These grains can be substituted by nutrient rich process discards and by-products such as citrus pulp. In this study, four mathematical models were used to describe the ruminal disappearance of dry matter (DM) and crude protein (CP) of orange, grapefruit, lemon, and tangerine pulps: (I) non-lagged simple Mitscherlich or exponential, (II) lagged simple Mitscherlich or exponential, (III) Gompertz and (IV) generalized Mitscherlich. Results of DM and CP degradability characteristics showed that all the models fitted well (r2 > 0.95) to the disappearance data and there were minor differences between the models in terms of statistical evaluations. Results also revealed that the models differed in the estimated parameters depending on the nature and structure of the model, and parameters included. Model III estimated negative values for the studied parameters making those biologically unacceptable. Only models I and II can be used for estimating the degradability of DM and CP of citrus pulps. Citrus pulps, containing a large amount of ruminal degradable fractions, can be used as feed source in ruminants.

The implementation of the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation had been viewed to be the most ambitious chemicals legislation in the world and had placed a great challenge among the European Union (EU) member states. While government regulatory agencies were focused on how they can successfully implement and enforce the legislation, the industries’ concern was to guarantee the compliance with the regulation. Despite the progress, implementation of the regulation still experienced significant problems in the quality of the information provided by companies in their registration dossiers. Given that the success of the REACH process depended primarily on the adequate and reliable information supplied by industries, there was a need to document and manage the knowledge gained and generated since its implementation. Data from survey questionnaires revealed that major issues and concerns identified by industries consisted of communication problems among participants in the implementation of the Substance Information Exchange Forum (SIEF), failure to reach an agreement on the sharing of existing data, testing cost and lack of response from suppliers in the use of substance and correction of errors in the safety data sheet. To address these issues and concerns, the European Chemicals Agency (ECHA) implemented the SIEF for EU-based chemical industries to form consortiums and jointly carry out registration and dossier submission. Participants identified SIEF as the best practice enabling companies to complete their registration and dossier submission, as well as the most efficient method in complying with REACH regulation.

Published: September 2023

By 2030, the number of cows in the U.S. will have fallen by 50% and the cattle farming industry will be all but bankrupt. All other livestock industries will suffer a similar fate, while the knock-on effects for crop farmers and businesses throughout the value chain will be severe. Rethinking Food and Agriculture shows how the modern food disruption, made possible by rapid advances in precision biology and an entirely new model of production we call Food-as-Software, will have profound implications not just for the industrial agriculture industry, but for the wider economy, society, and the environment.

Madzhab Syafi’i merupakan madzhab yang tersebar luas ke berbagai pelosok dunia. Imam Syafi’i mempunyai murid-murid yang menyebarkan Mazhabnya keberbagai daerah. Pada akhir abad ke-3 muncullah thariqat Khurasan dan Iraq. Tentang faktor munculnya thariqat ini beserta pengaruhnya terhadap madzhab Syafi’i dan kenapa hanya ada dua thariqat ini, belum ada pembahasan khusus dari kitab-kitab klasik dan kontemporer. Karena itu penulis ingin mengkaji faktor munculnya thariqat Khurasan dan Iraq beserta Pengaruhnya Terhadap mazhab Syafi’i, agar bisa di pahami oleh pembaca. Penelitian ini menggunakan metode penelitian kualitatif yang memfokuskan pada penelitian perkembangan fiqh berkaitan thariqat Khurasan dan Iraq. Teknik Analisa data dilakukan dengan pendekatan content analisis. Adapun kesimpulannya ada 4 yaitu: 1) Faktor munculnya thariqat Khurasan dan Iraq ada empat yaitu: Banyaknya para ulama dan karangan dalam madzhab Syafi’i, Imam Syafi’i sering melakukan rihlah untuk mencari ilmu dan menyebarkan mazhabnya sendiri, tersebarnya murid Imam Syafi’i di berbagai tempat, berjauhan tempat tinggal para fuqaha syafi’iyyah, konsistennya para Ashhab dalam menyebarkan madzhab. Kemudian terkhususnya thariqat hanya kepada Khurasan dan Iraq karena ada empat alasan: Negara Islam pada masa itu tidak terpisah, Islam Ketika adalah satu negara besar yang tidak ada pembatasan-pembatasan, Rihlah dalam mencari ilmu adalah kebiasan ulama kita, Murid Imam Syafi’i bukan cuma orang Mesir. Namun, banyak dari luar mesir yang belajar ke Mesir. Dan tidak semuanya menetap di Mesir. 2) Pengaruh dari munculnya thariqat Khurasan dan Irak ada tiga yaitu: Terjadi kontradiksi dalam meriwayatkan pendapat dalam madzhab, terjadi kontradiksi dalam mentarjih pendapat dalam madzhab, dan bertambahnya bahan kajian terkait perkembangan madzhab Syafi’i.

Penelitian ini merupakan penelitian fikih, dengan menggunakan metode pendekatan kualitatif. Pendekatan kualitatif adalah suatu proses penelitian dan pemahaman yang berdasarkan metodologi yang menyelidiki suatu fenomena sosial Yakni, pendekatan yang berupaya memahami gejala-gejala yang dihadapi sehingga gejala-gejala yang ditemukan tidak memungkinkan untuk diukur oleh angka. Hukum dasar bunuh diri adalah haram namun jika Dalam kondisi perang membela agar tegaknya kalimat tauhid Allah maka diperbolehkan melakukan pengorbanan diri baik menggunakan bom ataupun tidak hal ini sesuai dengan keputusan Hasil Keputusan Musyawarah Nasional Alim Ulama Nahdlatul Ulama Tentang Masail Maudhuiyyah As-Siyasiayh dengan jelas diterangkan bahwa “Bunuh diri dalam Islam adalah diharamkan oleh agama dan termasuk dosa besar", perlu pemahaman dan pertimbangan yang serius dalam menentukan hukum bom bunuh diri. Bom bunuh diri dapat dikategorikan sebagi jihad yang dianjurkan agama, dan bisa dikategorikan sebagai teror yang diharamkan. Dikategorikan sebagai jihad apabila dilakukan sebagai aksi perlawanan terhadap penjajahan dan dilakukan di daerah yang sedang dijajah.

This research is motivated by the results of observations and results of the assessment results of lesson plans for Physical Education teachers at MTsN 4 Padang. Where the number of Penjasorkes teachers is 4 people and teachers are still not able to compile lesson plans in accordance with the limitations of writing lesson plans. To overcome this problem, a lesson plan preparation workshop will be held at the MGMP Activities at MTsN 4 Padang. This research is a madrasah action research. The research procedure in this study includes planning, action, observation and reflection. This study consisted of two cycles with four meetings. The subjects of this study were 4 Physical Education teachers at MTsN 4 Padang. Research data was collected using observation sheets. Based on the results of the research and discussion that have been put forward in the previous chapter, it can be concluded that the RPP Preparation Workshop through the MGMP can improve teachers' abilities in making RPP in Physical Education subjects. This is evidenced by an increase in the ability of teachers to prepare lesson plans from cycle I to cycle II. The average teacher's ability to prepare lesson plans in the first cycle was 73.06 in the sufficient category and in the second cycle was 84.23 in the good category.

The independent curriculum is a curriculum with various intra-curricular learning so that students are more optimal and have concepts and strengthen their competencies. The approach in this study uses a qualitative approach. Analysis of this research data using descriptive analysis. In this analysis, the data is interpreted descriptively and presented in a narrative manner. The results of the study revealed several problems found when implementing the 2022 independent curriculum in the two schools. In this independent curriculum, teachers are required to be more creative in designing teaching modules, learning objectives and the flow of learning objectives so that a teacher can no longer be careless in making lesson plans to design teaching and learning activities every week. The purpose of school work is only to strengthen the profile of Pancasila students. PS is still given to students every day but not only in class learning. Learning also needs to be carried out outside the classroom in order to increase the activity of students and innovate themselves
FORMACIÓN DOCENTES Y ESTUDIANTES EN REDES Brasil y Colombia: Una experiencia de pensar sobre las interacciones de culturas y saberes

The reflections presented that make up this text present a practical experience that emerges from the concrete action signed between teachers, from Brazil and Colombia, at some point in our articulations and discussions in relation to the action plans that took place in the VIII Ibero-American Meeting of Collectives and Networks of Teachers and Educators that carry out Research and Innovation from the School and the Community, held in Mexico, in July 2017. From the beginning of the formation in networks, we assume the experiences of the pedagogical expeditions promoting the debate and transformation of ideas, we plan teaching practices marked by the cultural exchange of knowledge between teachers and students of the respective countries. Adopting a critical stance of traditional educational and pedagogical systems, the proposed practices were systematized and based on the perspective of peer training (Suárez, 2006), as practicing subjects (Certeau, 1994, 1996) focused on pedagogical research in relation to the school experience (Larrosa, 2004), in and with the everyday (Certeau, 1994; Ferraço, 2003, 2007), this being thought of as the place of production of knowledge. In this article we aim to present sequences of teaching practices with vision and political-inventive dimension of everyday life. Invention that gives another meaning to the curriculum, articulating the teaching of philosophy favoring the awakening of our consciences, about ourselves and about the world in which we are inserted and how we relate to it, various strategies were adopted so that the teaching process and learning lead students to the experience of thinking about childhood (Kohan, 2013).
Sympletic Hamiltonian finite elements for semilinear wave and nonlinear Schrödinger equations

Published: September 2023

Las ondas no lineales modelan una variedad de escenarios, por ejemplo dinámica de fluxones, contracciones musculares y óptica no lineal. Dentro de los sistemas de onda no lineal más conocidos, suele ocurrir que estos también corresponden a sistemas Hamiltonianos, tales como la ecuación de onda semilineal y la ecuación de Schrödinger no lineal. El hecho que sean Hamiltonianos alza un problema que debe ser atacado al momento de simular numéricamente. Este es el de preservar el Hamiltoniano en largos periodos de cómputo. Esta tesis presenta un conjunto de esquemas de Elementos Finitos con estructura Hamiltoniana para los sistemas anteriormente mencionados. Estos métodos pertenecen a la clase de métodos Mixtos, de Galerkin Discontuno (DG) y Galerkin Discontinuo Hibridizado (HDG). Se muestran resultados numéricos para los métodos HDG para onda semilineal, donde se logra ver que el Hamiltoniano se preserva en cómputos largos, observando convergencia óptima con respecto a cotas de error derivadas para un análogo a este método para onda acústica.
Impacto del largo del ciclo semafórico en la operación de buses de transporte público

Published: September 2023

El transporte público de buses enfrenta actualmente como principal dificultad la continua disminución en las velocidades de desplazamiento, debido entre otras causas a la congestión vehicular, derivando en tiempos de viaje cada vez mayores para sus usuarios. Por este motivo, la infraestructura especializada para priorizar la circulación de buses se debe complementar con programaciones semafóricas adecuadas, ayudando así a reducir los tiempos de viaje. En base a esto último, el presente trabajo busca determinar cuáles son las programaciones semafóricas más adecuadas para la circulación y operación del transporte público, con foco en el impacto que el largo de ciclo tiene en dicha operación. Para evaluar el desempeño de distintas programaciones semafóricas, incluyendo largo de ciclo, porcentaje de reparto y desfase, se realizaron microsimulaciones utilizando como modelo de seguimiento vehicular el Intelligent Driver Model (IDM). Para la calibración del modelo se grabó mediante dron, en 3 puntos de la ciudad de Santiago, un total de 13.969 trayectorias, de las cuales 6.864 corresponden a automóviles, 584 a buses, 1.777 a otro tipo de vehículos y 4.744 a peatones. Estas trayectorias se procesaron mediante software de análisis de video y algoritmo genético, obteniendo 37 conjuntos de parámetros calibrados, 15 para automóviles y 22 para buses. Posteriormente, utilizando los parámetros calibrados se microsimularon mediante SUMO 6.804 configuraciones, realizando 6 réplicas para cada una, resultando en un total de 40.824 corridas de simulación ejecutadas. A partir de éstas, se determinó que, excepto en aquellas situaciones en las que la parada de buses se transforma en cuello de botella, tanto para las configuraciones que consideran corredor como vía mixta, el ciclo de 40 segundos (el más corto evaluado) es el que minimiza los tiempos de viaje obtenidos.
