Quality control of agricultural products is one of the study programs in the vocational school that applies online learning during the COVID-19 pandemic. The implementation of online learning in grade XI quality control has constraints, in which the average learning outcomes are still gaining at a low value of 58.06 in the analysis proximate material. At the time of observation, 70% of students did not understand the topic. Some students get difficulties in discovering or constructing a solution to a problem. Thus, an appropriate learning model is needed to improve student's learning outcomes. The purpose of this study was to determine the implementation of the learning cycle 5E model and discovery learning also to identify the differences in student learning outcomes between both models’ performance in the materials applying fresh milk quality standards. The research was conducted using the quasi-experimental (experiment classes used the learning cycle 5E model and control class used the discovery learning model). This study proved good analysis results. The application of the learning cycle 5E shows better results to the discovery learning model to improve student learning outcomes as evidenced by the fact that the average value of experiment classes is higher than that of the control class. The N-gain value of the experiment class is greater than that of the control class. Therefore, the learning cycle 5E model can improve students' learning outcomes.

Mosquitoes are animals that are very often found in everyday life. Starting from the home environment, to the school environment. Mosquitoes are also animals that can carry various diseases. The FMIPA UNY Biology Garden Laboratory is overgrown with trees and there is a pool of water from several ponds that are deliberately made. That is what makes mosquitoes like the environment that is included in their habitat. At the UNY Biology Garden Laboratory, which is one of the student learning locations, mosquitoes are found flying and sometimes disrupting learning activities because they can stab and cause itching. The disturbance is feared to cause mosquito-borne diseases in students who are active in biology gardens. So that mosquito traps are made that are modified and adapted to the needs and location of the target. The tool made is a simple mosquito trap that utilizes a pool of water from a fish pond and a net from mesh or paranet cloth. The target place is the FMIPA UNY Biology Garden Laboratory, especially the pool area. While the target is the larvae or seeds of mosquitoes left by the mother. It is expected that the mosquitoes will perch on the paranet to lay eggs, then the eggs will fall down and will be eaten by fish. This is in addition to reducing the growth of mosquitoes, it can also be used for alternative food for fish, which can reduce spending to buy fish feed. Key words: mosquitos, trap
