ARANG AKTIF AMPAS TEBU SEBAGAI MEDIA ADSORPSI UNTUK MENINGKATKAN KUALITAS AIR SUMUR GALI
Bibliographic record
Abstract
Penelitian ini tentang pemanfaatan karbon aktif ampas tebu sebagai media adsorpsi untuk menurunkan kandungan zat besi dan kesadahan pada air sumur gali. Tujuan penelitian untuk menentukan suhu karbonasi dan konsentrasi CaCO yang paling optimum untuk pembuatan karbon aktif serta mengkaji efektifitasnya dalam menurunkan kadar logam Fe dan kesadahan. Penelitian ini terdiri atas dua tahap, tahap pertama menentukan kondisi optimum karbon aktif berdasarkan SNI 06-3730-1995 yang didasarkan pada suhu karbonasi dan konsentrasi CaCO3 tahap kedua penggunaan karbon aktif dalam penyerapan logam Fe dan kesadahan berdasarkan ketinggian media. Pengukuran kadar Fe3+ menggunakan spektrofotometer, sedangkan pengukuran kesadahan dengan menggunakan titrimeteri EDTA. Hasil penelitian menunjukkan konsentrasi CaCO3 5,5.10-5 M dan suhu karbonasi 3500C paling optimum untuk menghasilkan karbon aktif paling sesusai SNI 06-3730-1995. Serapan optimum pada waktu operasi 2 jam pada media karbonaktif ampas tebu dengan tinggi 60 cm dapat menurunkan Fe sebesar 88% dan kesadahan 60%. Kata Kunci : Adsorpsi, Ampas Tebu, Besi, Karbon Aktif, Kesadahan.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
