Abstract

fetched live from OpenAlex

Permintaan akan buah nanas di dalam negeri terus meningkat, seiring dengan pertambahan jumlah penduduk dan meningkatnya kesadaran masyarakat terhadap manfaat vitamin yang terkandung di dalamnya. Namun demikian, keberadaan patogen menjadi kendala karena dapat menurunkan produksi tanaman nanas. Berbagai gejala bercak pada daun tampak di lapangan, yang mengindikasikan adanya serangan patogen. Penelitian ini bertujuan untuk mengidentifikasi gejala dan patogen penyebab penyakit bercak daun pada tanaman nanas serta menganalisis faktor-faktor yang mempengaruhi penyebarannya, guna memberikan dasar informasi bagi pengendalian penyakit yang lebih efektif. Penelitian dilaksanakan melalui sejumlah tahapan, seperti survei, evaluasi hasil survei, pengamatan gejala di lapangan, dan pengujian laboratorium terhadap patogen penyebab bercak daun. Sampel diambil secara purposive sampling dari tanaman nanas yang menunjukkan gejala bercak daun di Kabupaten Kubu Raya, Kalimantan Barat. Hasil penelitian menunjukkan bahwa tanaman nanas di wilayah tersebut terserang penyakit bercak daun dengan gejala berupa bercak berbentuk bulat dan teratur. Berdasarkan gejala tersebut, ditemukan keberadaan tiga jenis patogen, yaitu Curvularia sp., Fusarium sp., dan Discosia sp., yang diduga menjadi penyebab utama penyakit bercak daun pada tanaman nanas.

Not 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.
