Abstract

Tanaman siomak (selada wangi, nama latin Lactuca sativa L. var. augustuna) merupakan salah satu tanaman jenis selada yang mulai di tanam di Indonesia, salah satunya berada di Komunitas Pertanian Organik Brenjonk. Tanaman siomak kurang populer di Indonesia karena hanya sebagian orang yang mengetahui serta pemasaran dari tanaman siomak lebih banyak ditemukan di pasar swalayan. Tanaman siomak menjadi tanaman budidaya unggulan di Brenjonk, tetapi ditemukan terserang oleh penyakit bercak daun. Petani siomak Brenjonk melakukan beberapa pengendalian meskipun para petani memiliki informasi yang kurang mengenai penyebab penyakit yang menyerang. Tujuan dari penelitian yang dilakukan yaitu untuk mengetahui perilaku petani dalam mengendalikan penyakit bercak daun dan melakukan identifikasi patogen penyebab penyakit bercak daun pada tanaman siomak sehingga dapat menambah informasi penyakit pada tanaman siomak. Penelitian dilakukan di areal pertanaman Komunitas Pertanian Organik Brenjonk, Desa Penanggungan, Kecamatan Trawas, Kabupaten Mojokerto, Jawa Timur serta dilakukan kegiatan identifikasi di Lab Wilker Proteksi TPH Pasuruan. Penelitian dilaksanakan pada tanggal 18 September – 25 November 2023. Kegiatan penelitian diawali dengan melakukan survei petani dan lokasi pertanaman siomak yang ada di Brenjonk, melakukan pembuatan kuisioner, melakukan wawancara kepada petani siomak, dan melakukan pengamatan di lapang mengenai budidaya petani, teknik pengendalian oleh petani, serta penyakit yang menyerang di lapang. Metode selanjutnya yaitu dilakukan identifikasi penyebab penyakit bercak daun pada tanaman siomak. Berdasarkan hasil penelitian yang dilakukan terhadap tiga petani siomak Brenjonk, areal pertanaman siomak terbagi menjadi tiga lokasi yaitu greenhouse, pekarangan, dan lahan terbuka. Seluruh areal pertanaman menunjukkan bahwa tanaman siomak terserang penyakit bercak daun. Petani melakukan beberapa pengendalian meskipun tanpa mengetahui penyebab penyakit bercak daun. Petani siomak Brenjonk menerapkan pengendalian kultur teknis, hayati, mekanis, dan fisik karena berkonsep pertanian organik sehingga tidak dilakukan pengendalian kimiawi. Pengendalian yang dilakukan petani masih kurang efektif tetapi masih dapat menekan penyebaran dan perkembangan penyakit di lapang. Hasil identifikasi patogen penyebab penyakit bercak daun pada tanaman siomak disebabkan oleh Cercospora sp. yang menyebabkan kerusakan mencapai 50% sehingga mengurangi hasil produksi dan pendapatan petani.

English Abstract

The siomak plant, also known as fragrant lettuce (Lactuca sativa L. var. augustuna), is a type of lettuce that has recently been introduced to Indonesia. Despite its potential, the siomak plant is not yet widely known in Indonesia and is mainly sold in supermarkets. It is grown in the Brenjonk Organic Farming Community, where it is the flagship crop. Unfortunately, it has been found to be susceptible to leaf spot disease. Siomak farmers exercise some control over leaf spot disease, despite having limited information about its cause. The research aimed to identify the pathogen responsible for leaf spot disease in siomak plants and to observe the behaviour of farmers in controlling the disease. The research aimed to identify the pathogen responsible for leaf spot disease in siomak plants and to observe the behaviour of farmers in controlling the disease. The findings will contribute to the understanding of diseases affecting siomak plants. The research was conducted in the plantation area of Brenjonk Organic Farming Community, Penanggungan Village, Trawas Subdistrict, Mojokerto Regency, East Java. Identification activities were carried out at the Laboratory of the Pasuruan TPH Protection work area. The research was conducted from 18 September to 25 November 2023. The research activities commenced with a survey of farmers and siomak plantation locations in Brenjonk. Questionnaires were created, and interviews were conducted with siomak farmers. Observations were made in the field regarding farmer cultivation, control techniques, and diseases that affect the crops. The subsequent step involved identifying the cause of leaf spot disease in siomak plants. The planting area for siomak, as determined by research conducted on three Brenjonk farmers, is divided into three locations: greenhouses, yards, and open land. The entire planting area was affected by leaf spot disease. The farmers implemented some control measures without knowing the cause of the disease. Brenjonk siomak farmers implement a range of technical, biological, mechanical, and physical controls in line with the principles of organic farming, in order to avoid the use of chemical controls. While these controls may be less effective, they are still able to suppress the spread and development of disease in the field. Leaf spot disease in siomak plants is caused by Cercospora sp., resulting in up to 50% damage and reduced production and income for farmers.
