This research is a descriptive research that aims to describe the metacognition of high school students in solving mathematical problems regarding students' academic abilities. The subjects were students in grade XI on a High School that selected based on certain criteria with snowball sampling technique. The data were collected through problem-solving test which was supported by interview data. Based on the research result, can be concluded that students with high and low academical abilities had an awareness of the facts they had and were aware of how to use a strategy. However, only high-ability students had an awareness of when and why a strategy should be applied. It showed that in solving mathematical problems students with high academical ability involve three aspects of metacognitive knowledge namely declarative knowledge, procedural knowledge, and conditional knowledge nicely, while students with low academical ability only involve two aspects of metacognitive knowledge i.edeclarative knowledge and procedural knowledge.

This research aimed to describe the types of errors made by students in solving mathematical problems in the Two-Linear Linear Equation System and the factors causing students to make mistakes. The research subjects consisted of 2 students of class IX.A who were selected based on how many errors were made in solving math story problems. The instrument used is a written test that contains 1 item description and interview guidelines. The errors analyzed are categorized using the Newman error category which consists of 5 errors, namely reading errors, misunderstanding, errors in transforming, processing errors and errors in writing the final answer. The results showed that based on the Newman error criteria, the errors that occurred were not being able to write down what was known and what was asked, not being able to make a mathematical model correctly, unable to use procedures, wrong in using count operations and unable to conclude the final results. The cause of students making mistakes is not understanding the information in the problem, lack of accuracy of students, and lack of skills, forgetting, and hurrying in answering questions. The results of this study are expected to add insight into the types of errors made by junior high school students in the material system of linear equations of two variables, especially in working on problems related to everyday life so that in the learning process mistakes made can be minimized immediately.

This study explores the impact of transitioning from traditional paper-based worksheets to spreadsheet-based instruction on students' Opportunity to Learn (OTL) in a Linear Algebra course. Conducted with 37 undergraduate mathematics education students, the research employed a qualitative exploratory approach to examine changes in student engagement, conceptual understanding, and pedagogical awareness. The intervention began with procedural paper-based tasks and gradually introduced spreadsheet environments designed to foster conceptual exploration and mathematical argumentation. Data were collected through observations, student artifacts, and interviews, and analyzed using content analysis and learning trajectory comparison. The findings reveal that spreadsheet-based instruction enhanced computational accuracy, facilitated independent exploration, and promoted metacognitive engagement. A comparison between the hypothetical learning trajectory (HLT) and actual learning pathway (ALT) showed that students exceeded expectations, demonstrating improved conceptual reasoning and reflective thinking. The study concludes that spreadsheet integration—when embedded in argumentation-based learning—serves as a transformative pedagogical tool, expanding instructional quality and deepening students’ opportunity to learn in higher mathematics education.

Mathematical literacy is essential for students to apply mathematical reasoning in real-world contexts, yet its development often relies on foundational knowledge. Understanding how the mastery of prerequisite knowledge influences mathematical literacy can help formulate more effective teaching strategies. This study explores the relationship between students' mathematical literacy levels and their mastery of prerequisite knowledge in grade XI of high school. This study used a qualitative approach, five students were selected based on their mastery of prerequisite knowledge and mathematical literacy. Data were collected through tests and interviews, with methodological triangulation to ensure validity. The study's findings showed varying literacy outcomes according to mastery of prerequisites. Students with high-medium ability demonstrated competence in fairly complex tasks but struggled with advanced reasoning. In contrast, students with medium-high abilities could interpret and apply information well but faced challenges in solving high-level problems. This study suggests that the development of mathematical literacy is not always linear with the mastery of prerequisites, highlighting the importance of teaching strategies that integrate conceptual understanding with literacy skills. These insights contribute to mathematics education by emphasizing the role of foundational knowledge in improving students' mathematical literacy.

Climate change impacts global food productions, but its local effect on rice production, particularly on monsoon dominated regions remain less understood. Here, we assess climate change impact on rice production situated on Lampung Province, as one of the largest rice productions in Indonesia. The FAO AquaCrop model was used to predict rice productivity, incorporating climate projections from the CMIP5 model under medium (RCP 4.5) and high (RCP 8.5) emission scenarios. We simulated the model for fifteen locations representing districts in Lampung Province. Our results show that by 2050, the decreased rainfall is projected during the dry season and early rainy season, but the average monthly temperatures and evapotranspiration rates are expected to increase across all districts. AquaCrop simulated an increased rice productivity by +0.25 and +0.74 tons/ha for both scenarios in April planting season, but it decreased by -0.41 and -0.75 tons/ha in November planting season due to water stress. This research is important to provide a deeper understanding of the impact of climate change on rice productivity in Lampung Province. These findings highlight the need for adaptive strategies to sustain rice production under future climate conditions.

The nilem fish (Osteochilus vittatus) has high economic value, but its growth rate is relatively slow. One potential solution to accelerate its cultivation period is the use of recombinant growth hormone (rGH). This study aimed to evaluate the effect of oral administration of rGH derived from Epinephelus lanceolatus (rElGH) on the growth rate of nilem fish juveniles at different stocking densities. A completely randomized design with three replications was used in this study. Juvenile fish with an average length of 4.43±0.03 cm and weight of 0.96±0.03 g were reared in aquaria measuring 100 × 50 × 50 cm with a water height of 20 cm for 30 days. The fish were fed commercial feed containing 31–33% protein, with rElGH-supplemented feed given to satiation twice daily (at 08:00 and 16:00) during the first seven days, followed by regular feed without rElGH. The best production performance was obtained in the R30 treatment group (30 fish per 100 L with rElGH), with an absolute weight gain (AWG) of 3.4 g, a survival rate of 98.89%, and a specific growth rate (SGR) of 4.8% per day, indicating that nilem fish given rElGH grew faster.

Penelitian tentang analisis disparitas pemidanaan terhadap penyuapan dalam perkara tindak pidana korupsi. Penelitian ini dibuat untuk menganalisis akibat hukum adanya disparitas pemidanaan terhadap penyuapan dalam tindak pidana korupsi. Menganalisis bagaimana upaya menimalisir terjadinya disparitas pemidanaan terhadap penyuapan dalam tindak pidana korupsi. Analisis konsep disparitas pemidanaan terhadap penyuapan dalam tindak pidana korupsi di masa depan. Pendekatan yang digunakan adalah pendekatan hukum yuridis normatif, yang bersifat deskriptif analisis. Dari data diatas maka disparitas pemidanaan dalam tindak pidana korupsi dibutuhkan komitmen semua lembaga Negara yang memiliki kewenangan dalam penanganan dan penindakan kejahatan extra ordinary crime. Tindak pidana penyuapan dalam tindak pidana korupsi merupakan pekerjaan rumah bagi penegakan hukum di dalam pemberantasan korupsi, meskipun di beberapa sektor tingkat korupsi mengalami penurunan tapi di sektor politik mengalami peningkatan. Penyebab tingkat korupsi di sektor politik mengalami peningkatan mungkin salah satu penyebabnya adalah disparitas pemidanaan dalam pidana korupsi, mengingat dengan pengenaan pasal yang sama dan kerugian yang hampir sama ketika sebuah kasus korupsi melibatkan politisi maka vonis berbeda akan dialami politisi tersebut dimana kecenderungan yang ada vonis yang dijatuhkan lebih ringan dibandingkan dengan pelaku pidana korupsi dari non politisi. Hakim ujung tombak terdepan dalam memberikan putusan yang tegas dan memberikan efek jera, maka adanya pedoman pemidanaan yang dikeluarkan dalam bentuk Peraturan Mahkmah Agung dalam pemidanaan khusus terkait dengan Pasal 2 dan Pasal 3, maka PERMA No 1 tahun 2020 tidak banyak memberikan pengaruh dalam mengurangi dampak dari Disparitas Pemidanaan yang diujung tombaknya ada pada Hakim, sehingga regulasi yang ada saling kontradisi dimana undang-undang pemberantasan tindak pidana korupsi saling Tarik ulur dengan peraturan yang ada pada KPK, Kejaksaan, Pengadilan Tipikor (Hakim), sehingga masih belum dapat menciptakan suatu peradilan yang menlahirkan keadilan dan kesetaraan hukum pemberian pidana, yang memberikan kemungkinan bagi Hakim untuk memperhitungkan berat ringannya delik. Pendekatan diatas dapat dipergunakan dalam memperkecil dampak, menimalisir disparitas pemidanaan terhadap penyuapan dalam pidana korupsi di masa depan.
