Cuban Primary Education has the social responsibility of contributing to the comprehensive formation of the student's personality. However, the increasing level of complexity of social and educational environments, associated with the increase in anti-values, the poor perception of risk with minors from home, among other causes, generates the need for educational practices, even when working the cognitive and affective component, give more weight to the socio-affective aspect in the training process. In this order, the proposal made favors the educational influence for the socio-affective development of the primary school child based on the integration of school - family - community in the rural context.

The effect of temperature on compressive strength of concrete with the addition of kaolin as a substitute some fine aggregate

Fri, 21 Jun 2024 00:00:00 +0000

This research aims to; (1) Determine the feasibility of using kaolin from Pawangi Village, Capkala District, Bengkayang Regency, West Kalimantan Province when used as a substitute for some fine aggregate (sand). (2) To find out the description of compressive strength after burning and the model of the relationship between temperature and compressive strength of concrete with mixture, kaolin is used as a substitute for some fine aggregate (sand). (3) Determine the most optimal composition of kaolin mixture against the compressive strength of normal concrete and also due to the influence of temperature. The type of research used in this study is a qualitative experiment on the structure of concrete materials using kaolin as a substitute for fine aggregate. The concrete that is planned is of K-250 quality, in line with the quality standards of concrete used in residential structures (1 to 2 floors). The kaolin mixture used is a percentage of 0%, 25%, and 50% of the weight of sand according to the job mix formula for the quality of K-250 concrete. After 28 days the resulting concrete sample is fired in an oven (kiln).

Maintenance and upkeep of railway facilities is important to reduce the risk of work accidents. However, in some cases, there is equipment that is damaged and the equipment is very old. This is due to a lack of attention to public railway depot maintenance and maintenance work. This research discusses the evaluation of financing for maintenance and upkeep work, where in reality in the field, many railway maintenance facilities cannot be used properly due to negligence in the maintenance process. The aim of this research is to improve the maintenance and maintenance performance of railway depots in the aspects of structural buildings, rails and equipment supporting maintenance of railway facilities. The method used in this research is a literature review, case study, and survey conducted by distributing questionnaires to several experts, namely those carrying out maintenance activities at PT Kereta Api Indonesia (Persero), PT LRT Jakarta, and several sources who participated in the construction of the railway depot. The results of this research are the WBS of maintenance and upkeep work which is used to improve the maintenance and maintenance performance of railway depots.

Impact of virtual environments on learning binary inorganic compounds

Sun, 30 Jun 2024 00:00:00 +0000

The purpose of the research was to determine the effectiveness of virtual environments in learning binary inorganic compounds at the BGU level of the “San Isidro” Educational Unit. For this purpose, the research had a quantitative approach. Data collection was carried out through knowledge tests on the students (control and experimental group). The results obtained showed that at the control group level a mean of 3.86 was calculated, showing a standard deviation of 1.509 and a mean standard error of 0.302. On the other hand, the calculation showed that, for the experimental group, a mean of 4.46, a standard deviation of 1.576 and a mean standard error of 0.384 were calculated, which indicated that there was no significant difference between both groups when evaluating their knowledge Finally, as a conclusion, the importance of incorporating the “Virtual Quimi Project” project into the teaching activity, whose fundamental purpose is to introduce virtual environments oriented to the learning of binary inorganic compounds. In this sense, the main contribution that the research offers is to ensure that the teaching-learning process of this subject is more affective and effective for the teacher.

Development of operational standards procedures for maintenance and maintenance of public railway infrastructure infrastructure and electrical mechanical and architectural components in Wbs-based station buildings to improve maintenance and maintenance performance

A railway station is a place of departure and stoppage for trains. Poor, inappropriate maintenance and upkeep of infrastructure without strict supervision can result in physical damage to the infrastructure itself, thus losing its initial value and reducing the service life of the infrastructure. If the maintenance and upkeep of infrastructure in the transportation sector is not done properly, it can cause delays or, in the worst case, accidents. To ensure a high level of reliability and availability, the implementation of an effective maintenance program is very important. This is then clarified if poor maintenance and upkeep practices, such as in the transportation sector, can also affect the reliability of the transportation system and even cause life-threatening accidents. Damage or accidents that occur can also lower the company's image and customer or consumer trust. This research aims to develop Standard Operating Procedures (SOP) for maintenance and upkeep work on station buildings, architectural components, and mechanical electrical. The method used is based on a Literature Study, survey, and case study. The result of this research is the development of SOP maintenance and upkeep work on architectural components and mechanical electrical to improve maintenance performance.
