Abstract

The seawater of Karang Jahe, Rembang Regency, provides a highly saline, chloride-rich environment that accelerates the corrosion of iron materials widely used in local fishing activities. Although synthetic corrosion inhibitors are effective, their long-term application raises ecological concerns due to toxicity. Plant-based extracts offer a biodegradable and environmentally safer alternative. However, studies investigating locally sourced coastal plants under natural seawater conditions remain limited. This study is novel in that it evaluates locally sourced teak leaf (Tectona grandis L.f.) and tengar bark (Ceriops tagal) extracts from the Karang Jahe coastal area as eco-friendly corrosion inhibitors in natural seawater media. Immersion experiments showed a consistent decrease in corrosion rates with increasing inhibitor concentrations. After 20 days of immersion at 20 ppm, inhibition efficiencies of 90.75% for teak leaf extract and 93.49% for tengar bark extract were achieved, demonstrating strong and sustained corrosion protection under realistic marine conditions. Peak efficiencies were observed after 10 days, suggesting effective early stage adsorption of the inhibitor molecules on the iron surface. Overall, tengar bark extract demonstrated stronger corrosion protection. This finding highlights its potential as a locally sourced and environmentally friendly inhibitor for marine applications.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh bahan ajar berbasis website terhadap pemahaman konseptual siswa tentang kinematika gerak lurus. Penelitian ini menggunakan pendekatan kuantitatif menggunakan desain eksperimental pretest-posttest satu kelompok. Sampel terdiri dari 35 siswa kelas X.1 SMA N 1 Tuntang yang diseleksi melalui random sampling. Data dikumpulkan menggunakan tes pilihan ganda tiga tingkat untuk mengukur pemahaman konseptual siswa. Hasil penelitian menunjukkan bahwa rata-rata nilai pretest adalah 58,54, yang meningkat menjadi 81,00 pada posttest. Persentase kelengkapan pembelajaran meningkat dari 22,86% menjadi 82,86%. Analisis N-Gain menghasilkan skor rata-rata 0,51, dikategorikan sebagai peningkatan sedang. Temuan ini menunjukkan bahwa bahan ajar berbasis situs web efektif dalam meningkatkan pemahaman konseptual siswa tentang kinematika gerak lurus. Oleh karena itu, integrasi media digital interaktif direkomendasikan untuk mendukung pembelajaran fisika di era digital.

Abstract

This study aims to develop and validate an Arduino-based system for monitoring water quality using NodeMCU ESP8266 to measure Total Dissolved Solids (TDS), Electrical Conductivity (EC), and water temperature in fish farming in buckets (Budikdamber). Budikdamber monitoring has never been done in real-time with TDS–EC–temperature at the same time, as well as analyzing the influence of fish density variations on water quality dynamics. ADDIE's development model is used through the stages of analysis, design, development, implementation, and evaluation. The prototype was validated and calibrated with standard instruments, and its accuracy was tested using Pearson, MAE, RMSE, and MAPE correlation. The results showed a high measurement agreement between the prototype and the standard tool, with Pearson correlation values of 0.907 (TDS), 0.973 (EC), and 0.936 (temperature), respectively, signifying the high validity and precision of the measurements. Regression equations result in an effective calibration model to correct measurement bias. water- quality dynamics & density effect to Observations of various fish densities indicate that an increase in the number of fish increases TDS, EC, and pH fluctuations and also affects the thermal characteristics of the water. Regression analysis showed that fish density was a strong predictor of increased TDS (R² = 0.9098) and EC (R² = 0.8988). The study concluded that the prototype is feasible to be used for real-time monitoring and that the ideal density of Budikdamber ranges from 55 to 70 heads per 80-liter bucket to maintain water quality stability. Water management: the safest and optimal time to change pool water is in the afternoon, around 5:30–7:00 PM, with a waiting period of 4-5 days, offering a scalable physics-based monitoring framework for micro-aquaponics systems
