No full textAs a country with a very high level of fish consumption, Japan relies heavily on the marine sector, especially in the activity of catching abundant marine products. Various types of fishing gear have been developed, ranging from traditional equipment to modern technology using machines and robots. These efforts are made by the Japanese government to ensure the availability of fresh fish for its people. This study aims to compare fish catches based on different colors of artificial bait and to identify and analyze the effect of bait color on the effectiveness of catches directly in the field. The research material focuses on the comparison of artificial bait colors to improve the catch of the pole and line method. The method used in this research is descriptive qualitative. The results showed that silver-colored bait was most effective in attracting skipjack, with the highest number of catches compared to the other two bait colors. In addition, catches were recorded significantly higher in the morning session (07:00-11:00) compared to the afternoon and evening sessions. The fishing location factor also contributed to the variation in catch, with some locations showing higher levels of productivity. These findings confirm the importance of choosing the right time, location and bait color to optimize catch using the pole and line method.Sebagai negara dengan tingkat konsumsi ikan yang sangat tinggi, Jepang sangat bergantung pada sektor kelautan, khususnya pada aktivitas penangkapan hasil laut yang melimpah.

Analisis Respon Udang Vaname (Litopenaeus Vannamei) Pada Pl 20 Terhadap Pemberian Pakan Maggot (Hermetia Illucens) : Analisis Respon Udang Vaname (Litopenaeus Vannamei) Pada Pl 20 Terhadap Pemberian Pakan Maggot (Hermetia Illucens)
No full textThis study aimed to evaluate the feeding response of vannamei shrimp (Litopenaeus vannamei) at the post- larval stage (PL20) to the administration of natural feed in the form of fresh maggots. The research was exploratory and employed a laboratory-based experimental design. A single treatment was applied : fresh maggots were provided at daily dosage of 20% of body weight, administered three times per day. The experiment was repeated ten times. Data were analyzed descriptiptively. Results showed that L. vannamei exhibited a positive feeding response to maggot supplementation. This was indicated by : (1) immediate acceptance of maggots from the first day, (2) increased pereopod activity observed by the third day as shrimp began carrying maggots, (3) improved feeding behavior over time-initial slow responses on day one transitioned to rapid movement toward the feed on subsequent days. Water quality parameters remained within suitable ranges : temperature 29-20 °C, dissolved oxygen 5.3-6.5mg/L, salinity 31 ppt, pH 7.9-8.0, and ammonia (NH3) 0.2-2.0 mg/L. These findings suggest that fresh maggot larvae are a promising natural feed alternative for L, vannamei PL 20, particularly during early feeding adaptation.

The Use of Fraction Tiles as Manipulative Media in Fraction Learning to Improve Algebraic Thinking Skills of Fourth Grade Elementary School Students
No full textAlgebraic thinking is a fundamental mathematical ability that supports students’ understanding of relationships, patterns, and structures, particularly in learning fractions at the elementary school level. This study aimed to examine the effectiveness of using Fraction Tiles as manipulative media in fraction learning to enhance fourth-grade students’ algebraic thinking skills. A pre-experimental method with a one-group pretest–posttest design was employed involving 30 elementary school students. The learning activities emphasized concrete manipulation, visual representation, pattern exploration, and symbolic expression of fraction relationships using Fraction Tiles. Students’ algebraic thinking abilities were assessed across four indicators: identifying equivalence and relationships among fractions, representing fractions in multiple forms, drawing simple generalizations from fraction patterns, and using mathematical symbols to express relationships. Data were analyzed using descriptive statistics and a paired-samples t-test. The results revealed a substantial improvement in students’ algebraic thinking, as indicated by higher mean posttest scores compared to pretest scores. The paired-samples t-test showed a statistically significant difference (p < 0.001), accompanied by a very large effect size (Cohen’s d = −48.0), indicating strong practical effectiveness. These findings suggest that the use of Fraction Tiles is highly effective in fostering algebraic thinking and provides a meaningful instructional approach for fraction learning in elementary education
