Abstract

Pollution in Jakarta Bay associated with terrestrial run-off and eutrophication. Bivalves have been recognized as aquatic organisms that play the most dominant role in aquatic ecosystems. Pb is an element that in many cases causes health problems in the liver, kidneys, hematopoietic system and nervous system. This study aims to analyze the bioaccumulation of Pb in the gills of P. viridis in Jakarta Bay, and its histological changes. Bioaccumulation analysis using the AAS and histology changes using transmission electron microscopy (TEM) methods. The results of AAS, showed that the value of Pb concentration in gill tissue at the two seasons did not show a noticeable difference. Pb concentrations in gills were lower at 1, 4, and 5 than at 2 and 3 stations. The results of ultrastructure analysis as an impact of Pb accumulation showed that thickening of the nucleus membrane, and a decrease in the number of microvilli. The thickening of the nucleus membrane, and the decrease in the number of microvilli are cellular responses to the entry of the Pb heavy metal into the cell. Besides, the results of this study showed inflammation, a decrease in the number of mitochondria, as well as causing cristae to be empty.

Abstract

Project Based Learning (PjBL) has many advantages but has not been widely implemented, let alone linked to entrepreneurial activities in schools. Entrepreneurship in schools, especially those taught by chemistry teachers, still has not produced crafts that link chemical knowledge therein. The aim of the research carried out was to analyze how much influence the application of the PjBL model has in improving students' creative thinking skills and entrepreneurial interest. The research method uses a one group pretest-posttest design approach. The research sample was selected using proportional sampling with data collection techniques, namely test techniques and distributing questionnaires which were then analyzed using the paired sample t test. Based on the results of the research that has been carried out, it can be concluded that there is a positive significant difference between before and after treatment. This shows an increase in students' creative thinking abilities and entrepreneurial interest after implementing the PjBL learning model.

Abstract

This research paper proposes the development of an application to support an intelligent learning environment in a project-based cooperative learning model on Java programming courses. The application is built using the Laravel framework where the end result later lecturers can easily see the student portfolio of each learning access on the java programming course. An intelligent learning environment will enable students to learn from their experiences, adapt to new input, and perform project tasks already assigned to lecturers. This application will also help teachers in groups that are adapted from the cooperative learning model of the STAD type. The proposed application will be designed to make it easier for teachers to form groups based on the ability of students from high, medium and low, so that the groups formed are not homogeneous groups. This application will be useful for a variety of study programmer that have practical programming courses devised. This paper will discuss the benefits of cooperative learning, project-based learning, and intelligent learning environments in the context of Java programming courses. It will also provide insights into the proposed application development process.  This application facilitates communication and discussion among students in a group that is easily connected with their lecturer, so that the lecturer can also monitor the activity of the group members. This paper will conclude with a discussion of the potential impact of the proposed applications on the field of education and the future in the learning environment.

Abstract

A flag is a rectangular or triangular piece of cloth or paper used as a symbol of the state, association, body, etc. or as a sign. It is often also used to symbolize a country to show its sovereignty. Along with the large number of countries, the country's flag also has many varieties and colors. The use of computers as a human aid is expected to the extent that the computer's ability can replace the limitations that humans have. Humans can recognize an object by using their eyes and brain, but if the eyes and brain cannot work properly it will hamper human work. In this research, training will be conducted on the Back Propagation Neural Network Architecture. Characteristic data for image recognition is obtained by extracting texture features and RGB color features. So that the network can recognize the flags by matching the feature data obtained from the training carried out. Characteristic data obtained from 24 data consisting of 16 training images and 8 testing images. From the results of the image network training can be identified properly, the accuracy rate of object identification is 87.50%. GUI users are able to identify flag images based on RGB text and color features.
