Persebaran Total Petroleum Hidrokarbon (TPH) pada Tanah Tercemar Minyak Mentah (Crude Oil) di Kelurahan Kampung Enam, Kecamatan Tarakan Timur, Kota Tarakan
Bibliographic record
Abstract
Proses produksi minyak bumi yang dilakukan di Kelurahan Kampung Enam mengakibatkan tanahterkontaminasi minyak bumi. Tanah yang terkontaminasi minyak bumi berubah warna menjadi kehitaman.Aktivitas industri minyak bumi tersebut berpotensi mencemari lahan di permukiman penduduk sekitar.Penelitian ini bertujuan mengkaji tingkat pencemaran minyak bumi pada lahan sekitar sumur minyak bumi dankarakteristik sifat fisik tanah di Kelurahan Kampung Enam. Metode penelitian ini dilakukan dengan melakukanobservasi dan survey lapangan diikuti dengan pengambilan sampel di lapangan. Pengambilan sampel dilakukanpada 1 titik di sekitar sumur aktif, 3 titik di sekitar sumur mati, dan 3 titik prakiraan arah persebaran.Karakteristik sampel yang dilakukan adalah uji kandungan TPH tanah, tekstur, pH dan kadar air tanah. Hasil ujilaboratorium menunjukkan tanah memiliki tekstur pasir berlempung, dengan pH 7, memiliki kadar air sebesar4,5%-5,76%, dan memiliki kisaran TPH 2,03% – 14,47%. Berdasarkan hasil uji lab tersebut perlu dilakukanupaya pengelolaan agar kandungan TPH dapat terdegradasi lebih cepat dalam tanah.Kata Kunci : Minyak Bumi; Tanah; Pencemaran; TPH; Persebaran

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.
