Abstract

Tujuan penelitian ini adalah untuk memperoleh deskripsi mengenai penerapan model pembelajaran problem based learning untuk meningkatkan hasil belajar siswa kelas X MIPA 3 SMA Negeri 5 Palu pada materi fungsi komposisi. Jenis penelitian adalah Penelitian Tindakan Kelas. Desain penelitian mengacu pada model Kemmis dan Mc. Taggart. Penelitian ini berlokasi di SMA Negeri 5 Palu. Subjek penelitian ini adalah siswa kelas X MIPA 3 yang berjumlah 30 siswa. Hasil penelitian menunjukkan bahwa penerapan model pembelajaran problem based learning dapat meningkatkan hasil belajar siswa, dengan tahapannya yaitu: 1) konsep dasar; 2) pendefinisian masalah; 3) belajar mandiri; 4) belajar kelompok; dan 5) penilaian; Hasil Peningkatan hasil belajar maatematika siswa dari hasil tes akhir tidakan siklus I sebesar 73,33% Pada siklus II sebesar 83,33%. Hasil observasi aktivitas guru dan siklus pada siklus I berada pada kategori cukup. Pada siklus II skor total hasil observasi aktivitas guru dan siswa siklus II berada pada kategori baik. Dari hasil penelitian menunjukkan bahwa penerapan model Problem Based Learning (PBL) dapat meningkatkan hasil belajar siswa pada materi fungsi kompossisi di kelas X MIPA 3 SMA Negeri 5 Palu. Abstract: This research aims to obtain a description of the implementation of problem based learning model to improve student learning outcomes in grade X MIPA 3 SMA Negeri 5 Palu on composition of function. This type of research was Classroom Action Research. The research design refers to the model of Kemmis and Mc. Taggart. This research was located at SMA Negeri 5 Palu. The subjects of this study were 30 students of grade X MIPA 3. The results of the research show that the implementation of problem-based learning modelcan improve student learning outcomes, with the following stages: 1) basic concepts;. 2) defining the problem; 3) self-study; 4) study groups; 5) assessment; The increase of students learning outcomes based on the results final test: Action in cycle I is 73.33% and cycle II is 83.33%. The result of observation of teacher activity in cycle I is in the category of sufficient. In cycle II, the total score on the result of the observation of teacher and student activity in cycle II is in good category. The resultindicates that the implementation of Problem Based Learning (PBL) model can improve students learning outcomes on composition of function in grade X of MIPA 3 SMA Negeri 5 Palu. Keywords: problem based learning; learning outcomes; composition of function

Abstract

Tujuan penelitian ini adalah menghasilkan model pembelajaran berbasis pengajuan masalah matematika yang dapat meningkatkan kemampuan berpikir kritis matematis siswa SMP yang valid. Penelitian ini menggunakan pendekatan penelitian dan pengembangan (R&D) yang merupakan tahap pengembangan sebagai lanjutan dari tahap Studi Pendahuluan. Hasil dari tahap pengembangan menghasilkan model pembelajaran berbasis pengajuan masalah matematika yang valid. Kesimpulan penelitian ini bahwa model pembelajaran berbasis pengajuan masalah matematika memuat komponen sintaks yang terdiri atas 6 fase yaitu 1 Persiapan, 2, Penyajian informasi, 3 Pemberian Rangsangan, 4 Pengajuan soal, 5 Pembimbingan dan 6 Evaluasi, sistem sosialnya yaitu pembelajaran berpusat pada proses pengajuan soal, prinsip reaksinya yaitu guru membimbing, mengevaluasi dan memberikan umpan balik proses pengajuan masalah matematika, sistem pendukungnya adalah situasi masalah atau soal-soal yang merangsang siswa untuk mengajukan soal. Dampak instruksionalnya yaitu meningkatnya kemampuan berpikir kritis, sedangkan dampak pengiringnya yaitu kepercayaan diri, kemampuan untuk mengendalikan diri, dan memotivasi.

Abstract

Drought is one of the hydrometeorological disasters that has a significant impact on the agricultural sector, water availability, and food security, thus requiring an accurate and adaptive early warning system. This study aims to develop and evaluate a drought Early Warning System (EWS) model based on a combination of multi-variable agrometeorological parameters using a hybrid approach of Singular Spectrum Analysis (SSA) and Adaptive Model-Based Prediction (AMBP). The agrometeorological data used includes rainfall, air temperature, humidity, solar radiation, wind speed, and other supporting variables processed in the form of monthly time series over a period of ten years. The SSA method is used to perform signal denoising and extract dominant components from the data, while AMBP is applied as an adaptive predictive model to generate SPI-6 drought index forecasts. Model performance is evaluated using RMSE and the coefficient of determination (R²) in the model training and evaluation phases. The results show that the hybrid SSA–AMBP model has the best performance compared to single methods, with an RMSE value of 0.149 and R² of 0.983 in the model training phase, and an RMSE of 0.176 and R² of 0.941 in the model evaluation phase. In addition, the 2026 prediction results show a seasonal pattern with indications of a moderate dry period from October to November. These findings indicate that the developed model demonstrates relatively high predictive accuracy and stability based on RMSE and R² evaluation metrics within the SPI-6 dataset used in this study, and it has the potential to serve as a conceptual basis for decision-support in drought risk mitigation, water resource management, and sustainable agricultural planning.
