Abstract

Indonesian students’ scientific literacy remains relatively low, as indicated by PISA results, which placed Indonesia among the bottom 10 countries, and AKMI data shows that 51% of madrasah students are at the "basic" level. This study aims to develop scientific literacy-based Student Worksheets (LKPD) on classifying living organisms for learning. The research method employed is Research and Development (R&D) using the 3D model, which includes the Define, Design, and Develop stages. The research subjects included material and media expert validators, a class X biology teacher, and 25 class X students at MAN 1 Bandung. The instruments used were validation sheets, readability questionnaires, and student response questionnaires. Data analysis was conducted using qualitative and quantitative approaches with the help of a Likert scale. The results showed that the developed LKPD is feasible for use, with material expert validation at 85.556% (highly valid), media expert validation at 72.25% (valid), teacher readability at 80.80% (easy to understand), student readability at 85.35% (easy to understand), and student responses at 86% (highly positive). Therefore, the scientific literacy-based LKPD on the classification of living organisms is suitable for use and can serve as effective teaching material to support the learning process.

Abstract

Scientific literacy is recognized by the World Economic Forum as one of the 16 essential skills for the 21st century. However, the scientific literacy of Indonesian students remains relatively low based on PISA results. This study aims to examine the enhancement of students' scientific literacy through implementation of Problem Based Learning (PBL) model based on socio-scientific issues (SSI) on ecosystem learning. This research used a quasi-experimental study with a non-equivalent control group design. The population consisted off all 7th grade in the academic year 2024/2025, totaling 108 students. Two classes were selected as samples: 28 students in the experimental class and 26 students in the control class. Data collection instruments include tests, observation, and questionnaire. The data were analyzed using N-Gain to measure improvement and inferential statistics to test significance. These findings suggest that Problem Based Learning (PBL) based on socio-scientific issues (SSI) effectively enhances students' scientific literacy. This research can be an alternative strategy, and reference for teachers and schools in implementing innovative learning that supports scientific literacy development.

Abstract

The increasing demand for halal-friendly gelatin, combined with concerns over health risks associated with mammalian sources, has created a need for alternative raw materials. Fish scales from local species, such as parrotfish, offer a sustainable and promising option that has yet to be extensively explored. The study aims to investigate the physicochemical properties of gelatin extracted from the scales of the parrotfish (Scarus quoyi) scales. Response Surface Methodology (RSM) was employed to determine the optimal concentration of hydrochloric acid (HCl) and immersion time to maximize yield and quality. Physicochemical properties, including yield, moisture content, ash content, pH, and viscosity, were evaluated, and the structural characteristics of the gelatin were analyzed using Fourier-Transform Infrared Spectroscopy (FTIR). All processing steps were conducted in compliance with Halal Critical Control Points (HCCPs) to ensure the final product remained free from cross-contamination with non-halal substances. Response surface methodology optimization identified 4% HCl concentration and 29.4 hours of immersion as optimal conditions. These conditions produce gelatin with a yield, moisture, ash, pH, and viscosity are 14.5%, 4%, 0.48%, 4.15, and 1.78 cP, respectively. FTIR analysis confirmed that the extracted gelatin exhibited absorption peaks consistent with those of commercial gelatin, indicating a functional group similarity. Compared to gelatin from other fish species, parrotfish gelatin demonstrated a competitive yield and notably low moisture content, thereby enhancing its stability and storage potential. These findings highlight the potential of parrotfish scales as a sustainable source of halal gelatin, contributing to waste reduction and offering a viable alternative to mammalian gelatin.

Abstract

Abstract: Mercury is a dangerous contaminant for aquatic organisms. Seurukan fish (Osteochilus vittatus) is a type of fish in the Krueng Sabee river that is vulnerable to mercury exposure. The study's purposes were to investigate the effect of mercury on the biometric conditions of Seurukan Fish in the Krueng Sabee River, Aceh Jaya Regency. A total of 90 Seurukan fish consisting of 50 males and 40 females were collected from 3 research stations. The research stations represent the upstream area (Station 1), median river bodies (Station 2), and the downstream area (Station 3). Fish samples were taken from July to August 2019. The main parameters observed included class interval, sex ratio, length-weight relationship, condition factors, mercury concentration in sediment and liver, and hepatosomatic index. The results showed that the mercury content in the sediments of the Krung Sabee River was increased both spatially and temporally. Station 1, located in the upstream area, has the highest mercury content in the sediment was 6.278 ± 0.987 mg/kg. Mercury content in liver of Seurukan Fish ranged from 0.182 ± 0.100 mg/kg to 0.198±0.152 mg/kg. Mercury contamination in the Krueng Sabee river caused a decrease in biometric conditions of Seurukan Fish. Seurukan Fish exposed to mercury tended to have smaller size, an unbalanced sex ratio, low hepatosomatic index value, and negative allometric growth pattern.Abstrak: Merkuri merupakan salah satu jenis kontaminan berbahaya bagi organisme akuatik. Ikan seurukan (Osteochilus vittatus) merupakan salah satu jenis ikan di sungai Krueng Sabee yang rentan terpapar merkuri. Penelitian ini bertujuan untuk mengkaji pengaruh merkuri terhadap kondisi biometrik ikan seurukan di sungai Krueng Sabee, Kabupaten Aceh Jaya. Sebanyak 90 ekor ikan Seurukan yang terdiri dari 50 ekor jantan dan 40 ekor betina dikoleksi dari 3 stasiun penelitian. Stasiun penelitian mewakili wilayah hulu (stasiun 1), badan sungai (stasiun 2) dan wilayah hilir (stasiun 3). Pengambilan  sampel ikan dilakukan pada bulan Juli hingga Agustus 2019. Parameter utama yang diamati meliputi selang kelas, nisbah kelamin dan hubungan panjang bobot ikan, faktor kondisi, konsentrasi merkuri pada sedimen dan hati serta indeks hepatosomatik. Hasil penelitian menunjukkan bahwa kandungan merkuri di sedimen Sungai Krung Sabee mengalami peningkatan baik secara spasial dan temporal. Stasiun 1 yang terletak di wilayah hulu memiliki kandungan merkuri dalam sedimen paling tinggi yaitu sebesar 6,278 ± 0,987 mg/kg. Kandungan merkuri pada hati ikan seurukan di Sungai Krueng Sabee berkisar antara 0,182 ± 0,100 mg/kg hingga 0,198 ± 0,152 mg/kg. Kontaminasi merkuri pada sungai Krueng Sabee menyebabkan dampak negatif terhadap kondisi biometrik ikan seurukan. Ikan seurukan yang terpapar merkuri cenderung memiliki ukuran panjang dan bobot yang lebih kecil, nisbah kelamin yang tidak seimbang, dan nilai indeks hepatosomatik yang rendah serta pola pertumbuhan alometrik negatif.
