Abstract: Penelitian ini mengkaji bentuk-bentuk kesalahan beserta faktor penyebabnya yang dialami siswa kelas VIII SMP ketika mengidentifikasi sisi, rusuk, dan titik sudut pada bangun kubus. Desain kualitatif deskriptif dipilih agar&#8230; ar respons siswa dapat ditelaah secara mendalam tanpa adanya perlakuan atau manipulasi terhadap variabel penelitian. Sebanyak 30 siswa kelas VIII dijadikan subjek melalui teknik purposive sampling, dan 6 di antaranya dipilih untuk sesi wawancara semi terstruktur yang mewakili tiga tingkat kemampuan akademik, yaitu tinggi, sedang, dan rendah. Pengumpulan data dilakukan melalui tes diagnostik tertulis, wawancara yang direkam, dan dokumentasi. Analisis data mengacu pada model interaktif Miles dan Huberman yang terdiri atas reduksi data, penyajian data, dan penarikan kesimpulan, dengan triangulasi metode untuk menjaga keterpercayaan temuan. Hasil penelitian menunjukkan bahwa 46,67% siswa melakukan setidaknya satu kesalahan dalam mengidentifikasi sisi kubus, 63,33% siswa melakukan kesalahan terkait rusuk, dan 36,67% siswa mengalami kesulitan dalam mengidentifikasi titik sudut secara tepat. Tiga kategori kesalahan yang dominan teridentifikasi, yaitu kesalahan konsep berupa kekeliruan mengidentifikasi unsur geometris, kesalahan visualisasi yang berkaitan dengan kesalahan membaca representasi tiga dimensi, dan kesalahan prosedural dalam menghitung komponen geometris secara sistematis. Faktor penyebab meliputi dimensi internal, terutama lemahnya pemahaman konsep dan rendahnya kemampuan penalaran spasial, serta dimensi eksternal seperti minimnya media pembelajaran dan dominasi strategi mengajar berbasis ceramah. Temuan ini menegaskan perlunya pendekatan pembelajaran geometri bangun ruang yang lebih eksploratif, konstruktivis, dan berbasis media di jenjang SMP. This study investigates the types and underlying causes of errors made by eighth-grade junior high school students when identifying the faces, edges, and vertices of a cube. A qualitative descriptive research design was employed to examine students' responses in depth without manipulating any research variables. Thirty students from the eighth grade were selected through purposive sampling, and six of them participated in semi-structured interview sessions representing three levels of academic ability: high, moderate, and low. Data were gathered using written diagnostic tests, audio-recorded interviews, and documentation. Analysis followed the interactive model proposed by Miles and Huberman, encompassing data reduction, data display, and conclusion drawing, with methodological triangulation applied to ensure the trustworthiness of findings. Results indicated that 46.67% of students committed at least one error in identifying cube faces, 63.33% made errors related to edges, and 36.67% had difficulty identifying vertices correctly. Three dominant error categories were identified: conceptual errors, visualization errors, and procedural errors. Causal factors encompassed internal dimensions, particularly weak conceptual understanding and limited spatial reasoning ability, and external dimensions, including insufficient instructional media and lecture-based teaching strategies.

Anggraeni, Dewi, Sri Rezki Maulina Azmi
Abstract: Abstract: Student graduation is an urgent matter that is an indicator of the success of a university in producing its learning output. Several factors influence student graduation such as GPA, attendance, late taking credits,&#8230; dits, and lack of student involvement in academic activities. The urgency of this research, universities need a method that is able to predict student graduation early so that it can provide academic intervention to students who have the potential to experience delays or fail to graduate. However, limited access to real academic data is often an obstacle in the development of predictive models, Therefore, this study aims to implement the XGBoost algorithm to predict student graduation based on several academic variables, namely the Cumulative Grade Point Average (GPA), the number of credits taken, the percentage of attendance, and the average grade of students. Model training using the XGBoost algorithm using a simulation dataset of 500 students who are labeled as graduating into two classes, namely passed and failed. The results of the study showed that the classification performance was very good with an accuracy value of 99.6%, Precision 99.7%, recall 99.4%.      Keywords: xgboost algorithm; data mining; student graduation     Abstrak: Kelulusan mahasiswa merupakan hal urgensi yang menjadi indikator keberhasilan sebuah perguruan tinggi dalam menghasilkan output pembelajarannya.

PREDICTING TEA HARVEST PRODUCTION AT BAH BUTONG USING RANDOM FOREST AND HISTORICAL DATA

Prayoga, Hafizd, Ramadhan Nasution, Yusuf
Abstract: Abstract: Accurate forecasts of tea harvest production are important for workforce planning, factory operations, and marketing decisions, yet conventional estimation in plantations often relies on field experience and can&#8230; n be biased and less adaptive to changing conditions. This study aims to develop a Random Forest Regression model to predict tea harvest production at the Bah Butong tea plantation using historical operational and climate-related data. The dataset consists of 60 monthly records (2020–2024) with six predictor variables: rainfall (mm), number of rainy days, pest level, weed level, number of harvested trees and land area. Data were split into 80% training (48 samples) and 20% testing (12 samples). Model hyperparameters were optimized using RandomizedSearchCV with RepeatedKFold cross-validation (5 folds, 3 repeats). The tuned model achieved MSE of 668,980,524.45, RMSE of 25,864.66 kg, MAE of 19,838.69 kg, and MAPE of 7.59% on the test set. The results indicate that the model can provide practical production estimates, with errors averaging about 7–8% of the actual production. Feature importance analysis shows that the number of harvested tea bushes and cultivated area contribute most to predictions. Future work should extend the historical period and incorporate time-based features (seasonality/lag) for improved forecasting.             Keywords: hyperparameter tuning; production prediction; random forest; regression; tea harvest   Abstrak: Perkiraan akurat produksi panen teh sangat penting untuk perencanaan tenaga kerja, operasional pabrik, dan keputusan pemasaran, namun estimasi konvensional di perkebunan seringkali bergantung pada pengalaman lapangan dan dapat bias serta kurang adaptif terhadap perubahan kondisi. Studi ini bertujuan untuk mengembangkan model Regresi Random Forest untuk memprediksi produksi panen teh di perkebunan teh Bah Butong menggunakan data operasional dan data terkait iklim historis. Dataset terdiri dari 60 catatan bulanan (2020–2024) dengan enam variabel prediktor: curah hujan (mm), jumlah hari hujan, tingkat hama, tingkat gulma, jumlah pokok panen, dan luas lahan. Data dibagi menjadi 80% data pelatihan (48 sampel) dan 20% data pengujian (12 sampel). Parameter model dioptimalkan menggunakan RandomizedSearchCV dengan validasi silang RepeatedKFold (5 lipatan, 3 pengulangan). Model yang telah disempurnakan mencapai MSE sebesar 668.980.524,45, RMSE sebesar 25.864,66 kg, MAE sebesar 19.838,69 kg, dan MAPE sebesar 7,59% pada set data uji. Hasil tersebut menunjukkan bahwa model dapat memberikan estimasi produksi yang praktis, dengan kesalahan rata-rata sekitar 7–8% dari produksi aktual. Analisis kepentingan fitur menunjukkan bahwa jumlah semak teh yang dipanen dan luas lahan budidaya paling berkontribusi pada prediksi. Pekerjaan selanjutnya harus memperpanjang periode historis dan menggabungkan fitur berbasis waktu (musiman/lag) untuk peramalan yang lebih baik.   Kata kunci: panen teh; prediksi produksi; random forest; regresi; tuning parameter
