Nile tilapia (Oreochromis niloticus) culture requires an efficient and low-cost feeding strategy that can support fry growth and survival. This study aimed to analyze the effects of three types of natural feed, namely silk worms, earthworms, and snails, on absolute length growth, absolute weight growth, and survival of Nile tilapia fry. The study was conducted at the Aquaculture Laboratory, Faculty of Science and Computer Science, Universitas Muhammadiyah Gorontalo, from January 31 to March 2, 2026. An experimental method was applied using a Completely Randomized Design consisting of three treatments and three replications. A total of 45 Nile tilapia fry were reared in 9 plastic containers filled with 10 L of water, with 5 fish in each container. Growth and survival data were analyzed using ANOVA at the 5% significance level, while water quality was analyzed descriptively. The results showed that the type of natural feed had no significant effect on absolute length growth, absolute weight growth, and survival. Descriptively, silk worms produced the highest length and weight growth, with values of 2.99 cm and 6.37 g, respectively. Snails produced the highest survival rate of 86.66%. Water quality remained stable, with temperature ranging from 26.3 to 26.8°C, pH from 7.6 to 7.9, and dissolved oxygen from 5.2 to 5.6 mg/L. These findings indicate that silk worms are potential natural feed for improving growth, while snails support the survival of Nile tilapia fry.

This study investigates the use of experimental statistical analysis as an instructional approach to enhance students’ understanding of variable relationships in science learning. Many students tend to memorize experimental results without comprehending the underlying relationships between variables, resulting in limited analytical reasoning and superficial understanding. To address this issue, the present study explores how integrating basic statistical tools-such as mean, correlation, and regression-into experimental activities can strengthen conceptual comprehension, analytical reasoning, and scientific literacy. Grounded in constructivist and inquiry-based learning frameworks, the research emphasizes active engagement, where students participate in data collection, analysis, and interpretation to draw evidence-based conclusions. The study employed a quasi-experimental design involving science students divided into experimental and control groups. Both groups conducted similar laboratory experiments, but only the experimental group received explicit instruction in statistical analysis. Data were collected through pre-tests and post-tests to measure changes in students’ understanding of variable relationships. The results indicated a 25% improvement in the experimental group’s comprehension and reasoning ability compared to the control group. Students who applied statistical analysis demonstrated greater proficiency in interpreting data, identifying causal patterns, and connecting theoretical knowledge to experimental findings. In contrast, students taught through traditional narrative-based instruction showed minimal gains and relied heavily on memorization. The findings highlight the effectiveness of integrating statistical reasoning in promoting critical thinking, problem-solving, and scientific reasoning skills.

Science process skills and conceptual mastery are two crucial aspects. Conceptual mastery involves understanding scientific concepts, while science process skills encompass the ability to conduct scientific work, apply concepts, predict and inquire, interpret and communicate, hypothesize, conclude, plan, and conduct experiments. The aim of this study is to determine the relationship between science process skills and conceptual mastery through practical methods. The research method employed is quantitative with a correlational design. The study population includes all 11th-grade MIPA students at SMA Negeri 1 Bumi Agung, Lampung, with cluster random sampling used to select Class XI MIPA 1 as the sample. Data collection involved observation sheets and tests. Data analysis was conducted using Pearson product-moment correlation coefficient. The correlation analysis began with testing prerequisites such as normality and linearity, confirming that the data were normally distributed and linear. The correlation between science process skills and conceptual mastery yielded an pearson correlation coefficient (r) of 0.940 with N = 32. The critical value (r-table) was 0.349. Since 0.940 > 0.349 and the significance value (2-tailed) was 0.00 < 0.05, H0 was rejected and H1 was accepted, indicating a very strong relationship between science process skills and conceptual mastery through practical methods. Theoretically, these findings affirm the importance of practice-based learning in strengthening conceptual understanding. Practically, the results recommend integrating structured laboratory activities to enhance students’ scientific inquiry skills and conceptual mastery.
