Abstract

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.

Abstract

Pineapple productivity in West Borneo ranks second after bananas. One of the obstacles in pineapple cultivation is the presence of diseases that attack pineapple plantations. Symptoms of pineapple plant disease are an indication that the plant is attacked by pathogens. This study aims to identify pathogens that cause rot symptoms in pineapple fruit. The methods used in this study include surveys, survey evaluations, observation of symptoms in pineapple plantations, and laboratory tests of pathogens that cause pineapple fruit rot disease in Kubu Raya, West Borneo. Sampling was carried out by purposive sampling on pineapples with rot symptoms. Based on the results of the study obtained, it shows that the symptoms of pineapple fruit rot disease are characterized by the presence of soft rot that is blackish brown in color, rotten inside and emits a distinctive odor. Pineapple fruit rot is caused by the pathogens Curvularia sp. and Fusarium sp.
