Abstract

The purpose of this research is to examine the use of mathematics in the field of fisheries. This literature review research examines scientific articles or research journals consisting of 7 national journals and 5 international journals. The study is limited to taking the results of previous research which includes results related to the use of mathematics in the field of fisheries. The results of the study show that mathematics in the field of fisheries is proven to be widely used, both in the use of mathematics on basic matters or entrenched habits (ethnomathematics) such as counting the number of fish, calculating feed, calculating the area of ponds, calculating buying and selling, weighing seeds and feed and predicting schedules. harvest and others. The use of more specific mathematics, for example ethnomathematics in the cultivation process by Indramayu shrimp cultivators, application of mathematical modeling to determine the growth in weight of a fish species, construction and dynamic analysis of mathematical models of fishing systems (a case study of the Nusantara Brondong fishing port), mathematics as a tool for efficient fisheries management and economic growth in Gashua, application of optimum control on fish harvesting models in non-reserved zones taking into account reserve zones, mathematical modeling applied to renewable fisheries management, mathematical modeling of predator-prey fisheries in polluted water ecosystems, mathematical modeling applied to sustainable management of marine resources, marine capture fisheries production, rainfall, and sea surface temperature with vector autoregressive (VAR) models, mathematical models of fish harvesting with selective harvest policies, and least square method mathematical models (least square method) on body shape fishing boat

Abstract

Cognitive learning outcomes are one measure of the success of learning in the classroom. Learning outcomes will be related to the learning environment and learning processes related to the learning methods applied by educators. Choosing an appropriate method in a learning environment requires a study or research. The aim of this research is to find out whether the project based learning method can improve students' cognitive learning outcomes. This type of research is Classroom Action Research (PTK) by measuring students' cognitive learning outcomes using multiple choice tests for high school level in Geography lessons. The research results show that the application of the project based learning method can improve students' cognitive learning outcomes both classically and individually. The increase in learning outcomes can be seen from the increase in student learning outcomes from an average of 75.24 to 76.67 and individually from a very high percentage of 14.29 to 23.81 with learning implementation of 86.66% to 93.33%.

Abstract

Ornamental fish are a fishery commodity that has high economic value because of their attractive pattern, shape and color, especially freshwater ornamental fish. Betta fish (Betta sp.) is a type of ornamental fish that is very popular among Indonesian people, from children to adults because it does not require difficult care. One of the main attractions of betta fish is their unique fin shape and color pattern. This research aims to describe the effect of the color of the container on the brightness of the color of Betta fish (Betta sp.). This research is a type of experimental research that uses a Completely Randomized Design (CRD). Data collection uses observation and documentation techniques. This research used 4 different container treatments, namely: A: clear container, B: black container, C: blue container, and D: red container. Primary data collected included: (1) Changes in the brightness of the color of the betta fish, (2). Fish survival rate, and (3) Water quality parameters (temperature, pH, DO, ammonia). The observation results showed that treatment C (blue container) gave the highest increase in color brightness for betta fish, namely 2.25. Meanwhile, the lowest brightness value was found in treatment A (clear) = 0.75. However, the results of the Anova test showed that the use of different container colors did not have a real effect on increasing the brightness of the color of the betta fish
