Kemampuan Literasi Numerasi Matematika Siswa pada Materi Statistika
This study aims to explore high school students’ numeracy literacy skills in understanding statistical material through a descriptive qualitative approach. The research involved 25 tenth-grade students from SMA Negeri 2 Kejuruan Muda, selected purposively based on varying levels of numeracy proficiency. Data were collected using context-based diagnostic tests and semi-structured interviews, and analyzed through the stages of data reduction, presentation, and conclusion drawing. The findings indicate that only a small portion of students were able to accurately interpret numerical information and relate it to real-life contexts. Students with moderate proficiency tended to rely on procedural routines without deeper conceptual understanding, while those with low proficiency exhibited misconceptions in interpreting symbols and contextual meaning. These results highlight the need for more contextual and interactive teaching strategies to help students develop meaningful and relevant understanding of statistical concepts.

Pengaruh Puzzle Numerasi terhadap Kemampuan Numerasi Siswa Kelas V di Sekolah Dasar
This study aims to determine the effect of numeracy puzzles on the numeracy skills of 5th grade students at Sidosari Public Elementary School through pretest and posttest results. The research method used is quantitative research with a one-group pretest-posttest pre-experimental design to measure students' numeracy skills. The population used was 22 fifth grade students. The research instrument was AKM (Minimum Competency Assessment) questions in the Teaching Campus program which included pretest and posttest. Data were analyzed using descriptive analysis, normality tests, and statistical tests to determine whether the posttest scores increased significantly compared to the pretest scores. The statistical test used was a non-parametric test because the data was not normally distributed, so it used Wilcoxon Signed Rank. The results showed that the Wilcoxon Signed Rank test showed that there was a difference between the pretest and posttest of students after using numeracy puzzles with Sig. (2-tailed) of 0.000 <0.05. It can be interpreted that H₀ is rejected and H₁ is accepted, so there is an influence of numeracy puzzles on students' numeracy abilities in grade V of Sidosari State Elementary School. In conclusion, there is a significant influence in supporting the use of puzzle-based learning methods as a way to engage students and improve their numeracy abilities, as well as contribute to broader learning in developing critical thinking and problem-solving skills.

Model Regresi Linier Berganda untuk Peramalan Hasil Panen Kelapa Sawit
This study aims to forecast oil palm production using a multiple linear regression model by considering the relationships among several independent variables: rainfall , number of productive trees , harvested area , labor , fertilizer use , and a seasonal variable . Using secondary data from the company’s Daily Work Logs (Lembar Kerja Harian/LKH), the study employs the Ordinary Least Squares (OLS) estimator to obtain the coefficient vector. The results show a coefficient of determination of 65%, indicating that 65% of the variation in production can be explained by the input variables. The findings indicate that rainfall has a negative coefficient (-0.34305) suggesting a non-linear and inconsistent relationship with production levels. Thus, the study concludes that internal plantation factors—such as the number of productive trees play a more dominant role in increasing yield, whereas higher rainfall tends to negatively affect production.

Integrasi Kurva Horizontal To Vertical Spectral Rasio (Hvsr) dan Kurva Eliptisitas Gelombang Rayleigh untuk Penentuan Indeks Kerentanan Seismik (Kg)
This study aims to determine the seismic vulnerability index using microtremor data in Parigi City. A microtremor survey was conducted at 81 sites across the city. The data were analyzed to obtain the Horizontal to Vertical Spectral Ratio (HVSR) curve and the Rayleigh wave ellipticity curve. These two curves were combined to derive the dominant frequency (f₀) and amplification factor (A₀). The Rayleigh wave ellipticity curve was used to guide the determination of the dominant frequency (f₀) and amplification factor (A₀) on the HVSR curve. The results were then used to calculate the seismic vulnerability index (Kg). The peak of the Rayleigh wave ellipticity curve (Aₑₗₗ) can assist in identifying the dominant frequency (f₀), both when the A₀ peak is clearly visible (clear peak) and when there are multiple or unclear peaks. The use of Aₑₗₗ also helps refine the determination of A₀ values, yielding more stable results. The final mapping results show that the dominant frequency values range from 0.26 Hz to 2.9 Hz, the amplification factor ranges from 1.61 to 4.77, and the seismic vulnerability index ranges from 1.47 to 113.59. Conclusion, The integration of the HVSR curve and the Rayleigh wave ellipticity curve carried out in this study shows that both can be combined and complement each other. Keywords: Dominant Frequency (f0), Amplification Factor (A0), Seismic Vulnerability Index (Kg), Rayleigh Wave Ellipticity Curve, Horizontal-to-Vertical Spectral Ratio (HVSR) Curve

Studi Karakteristik Gelombang di Perairan Selat Makassar Menggunakan Model Numerik Spektrum Gelombang Resolusi Tinggi
Penelitian ini bertujuan untuk menganalisis karakteristik gelombang dan swell di Selat Makassar selama tahun 2021 menggunakan model numerik SWAN beresolusi tinggi. Data angin dari GFS dan kondisi batas dari BMKG digunakan untuk simulasi gelombang signifikan, dengan resolusi spasial 0,01°. Hasil simulasi dianalisis secara deskriptif kuantitatif untuk memahami pola spasial dan temporal gelombang. Penelitian ini menunjukkan bahwa dinamika gelombang di Selat Makassar dipengaruhi oleh monsun barat laut dan tenggara, dengan tinggi gelombang signifikan rata-rata dalam kategori rendah (0,5–1,25 meter) selama musim barat laut, dan rendah hingga sedang (0,5–2,5 meter) selama musim tenggara. Arah swell mencerminkan pola monsun dengan kategori dominan tenang (0,1–0,5 meter). Korelasi positif antara kecepatan angin dan tinggi gelombang (koefisien korelasi 0,36) menunjukkan kontribusi angin terhadap pembentukan gelombang, meskipun faktor lain seperti arus laut turut memengaruhi. Hasil penelitian menunjukkan bahwa pola angin, gelombang signifikan, dan swell di Selat Makassar tahun 2021 dipengaruhi oleh dinamika monsun barat laut dan tenggara. Monsun barat laut menghasilkan angin lemah hingga sedang (2–15 knot) dengan gelombang rendah (0,5–1,25 m), sedangkan monsun tenggara menghasilkan angin lebih kuat dengan gelombang rendah hingga sedang (0,5–2,5 m). Swell didominasi kategori tenang (0,1–0,5 m) sepanjang tahun, mengikuti perubahan arah monsun. Simpulan, korelasi antara kecepatan angin dan tinggi gelombang menunjukkan hubungan lemah (r = 0,36), menandakan adanya pengaruh faktor lain seperti arus laut dan swell regional. Kata Kunci: Gelombang Signifikan, Selat Makassar, Swell, SWAN, Monsun.

Pengembangan Soal Matematika Tipe Pisa Konten Bilangan untuk Literasi Matematis Siswa SMP
This study aims to develop a PISA-type test set based on real-world contexts integrated with strategies to see its effectiveness on junior high school students' mathematical literacy skills. The background of this study is the low achievement of Indonesian students' mathematical literacy in PISA, especially in Quantity content. The method used is design research with the Tessmer model through preliminary and formative evaluation stages (self-evaluation, expert review, one-to-one, and small group). The research subjects were students of class VIII.5 of SMP Negeri 11 Palembang. The results showed that the developed test set was very valid (82.9%) and practical (80%), and had very high reliability (α = 0.959). Students' mathematical literacy skills were in the high (33%), medium (50%), and low (17%) categories. The achievement of the Formulate indicator was 80.83%, Employ 76.94%, and Interpret 70.56%. These findings indicate that the problem set can strengthen students' mathematical literacy skills, especially in understanding context and developing problem-solving strategies, although mathematical interpretation and justification skills still need to be improved.

Analisis Kesalahan Peserta Didik dalam Menyelesaikan Soal Literasi dan Numerasi Berdasarkan Tahapan Kastolan
This study aims to analyze students' errors in solving literacy and numeracy problems based on Kastolan's stages and to identify the factors that contribute to these errors in order to minimize them during the learning process. This research employs a qualitative method with a study case. The subjects selected were six students out of a total of 36 students in class X-2 at SMAN 94 Jakarta. The results of the study indicate that the level of students’ literacy and numeracy skills influences the types and frequency of errors made. The conclusion reveals the factors behind each type of error: (1) conceptual errors occur due to a lack of understanding of the material and basic concepts, which leads students to choose incorrect formulas; (2) procedural errors arise from students’ inability to organize the steps of problem-solving in a sequential and systematic manner; and (3) technical errors result from inaccuracy in modeling the problem into mathematical form, such as writing incorrect variables or numbers. Keywords: Erros Analysis, Kastolan Stages, Literacy and Numeracy Issues
