This research aims to develop a method of mapping soil organic matter content in oil palm land using image processing technology. The data includes oil palm and bare land images and field measurements in pH, humidity, temperature, TDS, and EC. Correlation analysis showed a significant relationship between image spectral components (especially in the blue channel with r=0.3640) and soil organic matter content. The distribution of organic matter content showed concentrations in the 4.5-5.5% range with an average value of about 5%. The image processing-based predictive model successfully mapped the spatial variation of organic matter content with sufficient accuracy. The mapping results show spatial heterogeneity that can be used as a basis for implementing precision agriculture in oil palm lands. This research proves the potential of image processing technology as a non-destructive method for characterising and monitoring soil quality in oil palm plantations.

This study aims to obtain a description of student errors in the results of the mathematics final exams for the 2022/2023 school year based on the Newman Procedure. This type of research is qualitative. The research subjects used in this study were 29 students of class IX B MTs Hi Hayyun Salumpaga. The results of this study are in the form of descriptions of student errors and the causes of errors made by class IX B MTs Hi Hayyun Salumpaga. Based on the research results, it has been found that the most dominant errors are process errors with a percentage of 77%, transformation errors with a percentage of 82%, errors in understanding the problem with a percentage of 75%, and errors in writing the final answer with a percentage of 72%. The mistakes made in (1) the error in understanding the problem is where students do not write down what is known and what is asked, (2) transformation errors that occur, namely students misunderstand the meaning or concept to be used, (3) the process error made was not being able to carry out the process correctly and not being thorough, (4) errors in writing the final answer, namely the student made a mistake in writing the final answer and got an incorrect answer.

This study investigated the effect of numeracy skills on mathematics learning outcomes, specifically in the area of 2 plane figures, among 61 fifth-grade students in Labuan Regency. Using a quantitative correlational design, descriptive results showed that students' numeracy skills were in the good category (average 75.90) and learning outcomes were in the fair category (average 70.33). The Spearman rank correlation test showed a positive and significant effect, but the relationship was weak (r = 0.292; p = 0.023 < 0.05). These findings confirm that better numeracy skills contribute to higher learning outcomes, but the weak correlation underscores the important role of other factors (e.g., teaching methods, motivation). This study implies that teachers should optimize contextual numeracy-based learning to improve achievement, especially for complex concepts such as the area of a trapezoid.

Karies gigi merupakan salah satu penyakit terbanyak pada anak-anak di seluruh dunia. Pada rentang usia 3-6 tahun, sembilan dari sepuluh anak di Indonesia mengalami karies gigi. Silver diamine fluoride (SDF) merupakan salah satu pilihan dalam manajemen karies untuk menghambat aktivitas karies pada gigi sulung. Akhir-akhir ini SDF telah mendapatkan banyak perhatian karena kemudahan aplikasinya, efektivitas, harga yang terjangkau, dan waktu kerja yang singkat. Artikel ini bertujuan mengulas tentang perawatan silver diamine fluoride pada praktik kedokteran gigi anak.

The growing demand for twenty-first century competencies has increased the need for mathematics instruction that promotes conceptual understanding, reflective reasoning, and active student engagement. However, trigonometry learning in many secondary schools remains dominated by procedural instruction and formula memorization, causing students to experience difficulties in understanding conceptual relationships. This study aimed to investigate the implementation of the discovery learning model in improving students’ conceptual understanding of trigonometry among class XI students at SMA IT Persis Palu, Indonesia. The study employed a qualitative-dominant Classroom Action Research design conducted through two iterative cycles consisting of planning, action, observation, and reflection stages. The participants involved 23 students, with three focal informants selected purposively based on preliminary conceptual difficulties. Data were collected through conceptual understanding tests, classroom observations, interviews, field notes, and documentation. The findings revealed substantial improvement in students’ conceptual understanding across all indicators, including the ability to restate concepts, identify conceptual relationships, distinguish examples and non-examples, and apply trigonometric concepts accurately in contextual problem-solving situations. Learning mastery increased progressively until 88.24% of students achieved the minimum competency criterion in Cycle II. The study concludes that discovery learning effectively facilitates conceptual reconstruction, collaborative inquiry, and meaningful mathematical understanding in secondary trigonometry learning.
