Sperm motility is the main problem for honeybee's reproduction both in natural and in artificial insemination. Sperm produced only by sexually mature drone. Drone with high semen volumes can be seen by the external morphology like hairy in back and the existence of yellow stripes on their black abdomen. Semen samples were collected from the drone by the massage technique; these consist of massaging the abdomen of drone. This massage proceeded until penis and semen cream to yellow color, was Lea Tarliyah; Arief Boediono; Djoko Walujo

Abstract

Sperm motility is the main problem for honeybee's reproduction both in natural and in artificial insemination. Sperm produced only by sexually mature drone. Drone with high semen volumes can be seen by the external morphology like hairy in back and the existence of yellow stripes on their black abdomen. Semen samples were collected from the drone by the massage technique; these consist of massaging the abdomen of drone. This massage proceeded until penis and semen cream to yellow color, was produced. Semen taken out with spuit (3 ml) that contain a modification dilution media called "Kiev". Semen samples were collected; volume, abnormalities and motility were measured. The sexually mature drones were observed in 99.06% (213/215) drones with rare hair in back and 76.28% (164/215) with existence of the yellow stripes in the black abdomen. The color of sperm is yellowish white, which is different from mucous that is white. The average volume of semen samples from each drone is 1.11 μl. The average length of sperm is 217.57 μm (107.50-412.50 μm). The average length of sperm is 7,52 μm (5-1O μm). It's flipped tails, broken tails, double tails, and double heads with an average of 19.83%, 12.75%, 6.42%, and 2,25% respectively can determine abnormalities of the sperm. To conduct the artificial insemination, drone sperm should always be available. For this reason sperm should be preserved in an optimal condition storage temperature (5°C, 27 °c and 37°C) and glucose concentration (0%, 0,3%, 0,6%, and 0,9%) containing in the dilution media. This condition can be affecting the sperm motility. The highest motility is achieved when the sperm is kept in 0,9% glucose concentration and storage in 5 °C temperature. In this condition 0.19x106 sperm/ml can survive up to 36 hours. Moreover, the higher concentration of sperm motility up to 36 hours is achieved when sperm is kept in 5 Celsius temperature with different leves of glucose in dilution media. However statistically interaction between glucose concentration and temperature levels does not give significant affects.

Abstract

Learning media is one of the important things of learning tools that can increase students' interest in learning. This study aims to develop KALIKA (Five Character Cards) learning media on the classification of living things using the Educational Design Research (EDR) method to enhance student achievement. The development model refers to ADDIE with a design thinking framework. The research was carried out at one of the Junior High School in Bandung City, during the even semester of 2023/2024, with a focus on students in class VII, totaling 21 participants. Convenient sampling was utilized for subject selection. The data collection techniques in this research data are validation sheet, assessment formative (pretest and posttest), and questionnaire user response. The validation sheet and user response questionnaire were processed into percentage data using Microsoft Excel, while the formative test results were processed using the Wilcoxon Signed Rank Test statistical test and N-gain using SPSS. The results of this study showed that the validation test data obtained a validity percentage of 92.4% which categorized as very valid criteria, the Wilcoxon Signed Rank Test results state p <0.05 which means there is a significant difference between the pretest and post-test, and the results of the effectiveness test with N-gain effectiveness results of 0.31 which means the effectiveness of student learning is in the moderate category, and 95% students give positive response to KALIKA as learning media. This shows that using KALIKA learning media is quite effective as a support to improve student learning outcomes on the classification of living things. Previous researchers have never developed card-learning media using ADDIE with a design thinking framework, which contains five characters of 5 kingdoms of living things.
