The aim of this paper is to identify and analyze the role that the use of the computer has in stimulating the logical thinking of young schoolchildren. Through this, the purpose of the activity of solving operations with natural numbers, is to develop logical thinking, properly combining intuitive elements with abstract ones. Solving arithmetic problems, we can activate young students in the formation of skills and abilities to analyze the given situation, to intuit and discover the way to get what is required in the mathematical problem. This paper aims to prove that, if both traditional methods and computer-based teaching methods are used in the instructive-educational process, then school performance will register a significant increase in terms of quantity and quality. This experimental study started from the premise that solving arithmetic problems with the help of computer, using e-learning platforms is an important activity in the mathematics lesson in primary school through which we stimulate young students’ logical thinking.

Abstract Water pollution is now a major threat to the existence of living beings. Accordingly, Water quality monitoring is an important activity toward restoring water quality. As wetland eutrophication is one of the essential ecosystem elements, devastation of this element is a significant issue. The Trophic State Index (TSI) provides information about trophic condition of water bodies. This paper aims to conduct spatiotemporal monitoring for the eutrophication of the west part of Al-Hammar Marsh for the period 2013-2020. To this end, a satellite-based TSI computation model was developed and implemented by using a series of OLI Landsat satellite images. The results showed that there was no improvement in the eutrophication state in the marsh, the percentage of the low class of TSI decreased in 2015 and 2018 to 7.9% and 2.6% and increased in 2017 and 2020 to 39.8%, and 56.3%. In general, the TSI was in the poor class in all the considered periods. Fluctuation of quantity and quality of the inflow prevents restoring the eutrophication of the marsh because this process requires stability in the levels of inundation above the critical limits for the water depth and periods. Therefore, it is necessary to find suitable alternatives to provide water drainage in quantities and quality that ensure the sustainability of the marsh ecosystem.

The border is framed as a political/administrative element, as a space of contact of cultures and geographies, as a line of separation and permeability, generator of mobilities of different scales. During the last decades, the Iberian border has experienced depopulation dynamics and socio-economic reorganisations that have transformed the ways of working, the models of social organisation, occupation, and land use. In this context of growing mobility, tourism has become an important activity for the border due to its ability to generate employment and foster economic and social development. The mobilization of natural and cultural resources assumes significance in the valorization of these spaces, in line with the current policies of cross-border cooperation promoted by the EU and the efforts of the two Iberian countries. The border between central Portugal and Spain is taken as a study object, highlighting the existing dynamics and forms of cooperation, given the heritage values, capable of generating new attractions and functions in the oldest European border.

<p><strong>Abstract:</strong> Argumentation is an important activity in scientific exploration which has been agreed as a major component in science education. Quality argumentation skills are formed with the understanding of concepts owned by students. The current low level of argumentation skills is caused by the learning process. Application of guided inquiry learning with the STEM approach is expected to provide space to practice arguments based on the results of the constructs of students' concepts during learning. The results of the study stated that differences in initial abilities, the application of guided inquiry with the STEM approach affect the concepts understanding and argumentation skills of students. Also there is no interaction, between models and learning approaches and initial abilities towards understanding concepts and argumentation skills.</p><strong>Abstrak:</strong><em> </em>Argumentasi merupakan aktivitas penting pada eksplorasi ilmiah yang telah disepakati sebagai komponen utama dalam pendidikan sains. Keterampilan argumentasi yang berkualitas dibentuk dengan modal pemahaman konsep yang dimiliki siswa. Rendahnya keterampilan argumentasi saat ini salah satunya disebabkan oleh proses pembelajaran. Penerapan model pembelajaran inkuiri terbimbing dengan pendekatan STEM diharapkan dapat menyediakan ruang untuk melatih argumentasi berdasarkan hasil konstruk konsep siswa selama pembelajaran. Hasil penelitian menyatakan bahwa perbedaan kemampuan awal, penerapan inkuiri terbimbing dengan pendekatan STEM berpengaruh terhadap pemahaman konsep dan keterampilan argumentasi siswa namun tidak ditemukan adanya interaksi antara model maupun pendekatan pembelajaran dan kemampuan awal terhadap keterampilan argumentasi dan pemahaman konsep.

<p><em>Tea leaf plucking is an important activity that can determine the quantity and quality of tea production. Tea plantations characteristically have variations of slopes that affect the performance of the picking process. This study aimed to analyze the performance efficiency of tea plucking activities using plucking machines and scissors. Field data were collected from several blocks in the South Gambung and North Gambung afdeling. Data collected consisted of the elevation of the place, the slope of the land, the plucking area, plucking time, the number of pluckers, the plots length of the plucking activity, the width of the plots, and the harvested tea's weight. The data collected were processed into field capacity and tea plucking performance efficiency, which were then analyzed descriptively. Results showed that the slope of the land has an effect on work efficiency of 3.00%-8.68%. The effective and theoretical field capacity of tea plucking machines is 0.14 hectares per hour and 0.20 hectares per hour, respectively, while the scissors is 0.015 hectares per hour and 0.020 hectares per hour. The quality of tea harvested with machines that meet the requirements is 44.10%, better than scissors harvested, which is only 28.09%.</em></p>

Beekeeping is an important activity for the country, generating jobs and income for several rural families. However, the lack of technical assistance reduces the chances of success in production. So our objective with this work was to create a chatbot capable of taking technical assistance to small producers. We created the chatbee and delivered it to beekeepers and small producers who intend to enter the area, and at the end of 90 days we sent a form with some questions to be answered, and from the answers we realized that the function of bringing technical assistance was carried out by the chatbot.

AbstractThis article synthesizes current insights into supplier management practices that professional buyers can apply in the public procurement context. Specifically, it discusses the practices, rationale, and challenges associated with implementing supplier development as an important activity within supplier management practices. Drawing from the literature, the main arguments are on the applicability of indirect supplier development practices in the public procurement context. Therefore, it is concluded that public buyers can consider applying these practices in public organizations. However, caution should be exercised regarding the legal and regulatory structure that governs the country’s public procurement system. It further recommends empirical studies to be done on supplier development practices for local suppliers in specific public procurement projects.

The survey of the distribution and damage of the new pest Spodoptera frugiperda is an important activity to determine appropriate control measures. In addition, the search for natural enemies is also needed as an alternative to controlling these pests. The purpose of this study was to determine the level of damage and the types of natural enemies found in several locations in Banyumas Regency. The method used is perposive random sampling in Banyumas Regency in five sub-districts, namely Ajibarang, Baturaden, Gumelar, Kedungbanteng, and Sumpiuh. Observations were made at 08.00-11.00 WIB from March to June 2021. The results showed that the attack rate of Spodoptera frugiperda larvae varied at each observation location. The highest attack rate was in Sumpiuh and Gumelar Districts, followed by Ajibarang, Kedungbanteng and Baturaden Districts. One species of parasitoid was found, namely Apanteles sp. and 9 predators, namely Oxyopes salticus, Dermaptera, Holcocephala sp., Rainieria sp., Orius insidiosus, Dolichoderus sp., Paratrechina sp., Oecophylla sp. and Conocephalus longipennis. At the individual paraistoid level, Apanteles sp. became the most common, followed by the predatory fly Holcocephala sp. and ants Dolichoderus sp., fly Rainieria sp., ladybug Orius insidiosus, Dermaptera, ant Paratrechina sp., ant Oecophylla sp. and the grasshopper Conocephalus longipennis.

The translation of legal texts has become a very important activity in our modern, international societies. Globalization has created a great need for multilingual versions of all kinds of legal texts. However, both law itself and legal language and terminology have a special characteristic: they are system-bound. Every country or autonomous region sets up its own legal system, and this has far-reaching consequences not only for the drawing up and especially the translation of legal texts, but also for comparative law and international and European law. In this article, we describe certain typical features of the terminology of labour law and expand on one particular term to show the problems in translation work. The multilingual character of European law, the need for translation and the specific wording of labour law texts in the individual member states lead to many translation problems and to legal insecurity for citizens. By analysing relevant terms in the transport sector, we discuss current research that compares concepts and terms in European, Polish, Dutch and Belgian labour law.

Writing scientific papers is an important activity to improve teachers' quality, competence, and professionalism. Its implementation is marked by, among others, self-improvement through scientific research in the form of Classroom Action Research. During teaching and learning activities, teachers can research by developing various instruments and learning strategies. However, teachers rarely put their research results in writing in research reports and scientific articles. This community service activity aims to assist teachers in compiling Classroom Action Research reports and articles and explaining tricks to publish Classroom Action Research articles in reputable national journals. The implementation of the activities uses the methods of training, discussion, and direct mentoring so that the teacher can feel the process. This service activity received a good response, with the teacher's enthusiasm during the exercise, active discussions, and scientific reports and articles compilation. In the final discussion of this community service activity, teachers are very interested in publishing the results of their research, and it's just that teachers lack information about reputable journals. Through this activity, the ability of teachers to research and publish their research results can become practical innovations in the world of education, especially classroom learning.
