Abstract
Cadangan minyak bumi Indonesia yang semakin menipis mendorong manusia untuk terus mencari dan mengembangkan bahan bakar alternatif, salah satunya adalah kombinasi sistem bahan bakar minyak bumi dan gas atau biasa disebut diesel dual fuel (DDF) system. Jenis penelitian yang digunakan adalah metode eksperimental dengan tujuan desain rancang bangun sistem bahan bakar hingga menghasilkan suplai yang optimal dengan memanfaatkan kombinasi bahan bakar antara biosolar dan CNG (Compressed natural gas). Instalasi system DDF ini sedikit berbeda dengan instalasi mesin pada umumnya karena menggunakan alat pengontrol otomasi yang mengatur timing injection bahan bakar CNG, sedangkan pada sistem bahan bakar biosolar dilakukan modifikasi injektor (packing Injektor) untuk mencapai tingkat komposisi bahan bakar yang ideal. Penelitian ini menunjukkan performa mesin yang paling baik pada sampel DF CNG 1 dengan SFC 263 gr/kW.h dan efisiensi termal sebesar 32,91%. Penambahan CNG pada mesin DDF memberikan tingkat efisiensi biosolar mulai dari 39% hingga 74% dibandingkan menggunakan bahan bakar biosolar murni. ====================================================================================================== Ariana, I.M.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
