Abstract

Tempuyung (Sonchus arvensis L.) is known in Indonesia as traditional medicine. This study was conducted to observe diseases that attack tempuyung in organic cultivation. Ten accessions of sowthistle were collected from Dramaga, Cibadak, Cicurug, Lembang, Matesih, Sekipan, Tawangmangu, Batu, Banjararum, and Sumbersekar, with altitudes between 186-1280 m above sea level and rainfall of 988-2573 mm. The research was carried out in the organic experimental field of Cikarawang, IPB, Bogor, with a geographical location of 6o30' - 6o45' SL and 106o30'-106o45ยด EL and an altitude of 190 m above sea level. The research location is a lowland with 1618 mm of rainfall during the study. Pest identification was carried out in the Plant Clinic laboratory of the Plant Protection Department of IPB. Disease identification was carried out by taking symptomatic plants, then isolated and grown in PDA media and then identified. The results showed that the disease that attacked the sowthistle in this experiment was caused by the bacterium Pseudomonas sp and fungi Fusarium sp. The disease attack rate ranges from 32 to 60%. Disease attacks were controlled by removing the affected plants and then spraying with turmeric solution in a ratio of 1: 10. Pests that attacked sowthistle were snails, grasshoppers, fruit borer caterpillars, and panicle-sucking insects.

Abstract

Terdapat kecenderungan penurunan penggunaan benih bersertifikat, hal ini disebabkan adanya kecenderungan penurunan anggaran pemerintah yang dialokasikan pada sektor pendistribusian benih (bibit) perkebunan, sehingga praktis usaha penjualan benih banyak ditopang dari pangsa pasar non anggaran pemerintah. Rendahnya daya serap pasar benih bersertifikat dikarenakan beberapa faktor, yaitu : (1) Kesadaran masyarakat tentang mutu benih relatif rendah dan berdasarkan data perhitungan pendistribusian benih pada tahun 2010 penggunaan benih palsu dimasyarakat mencapai 60%, (2) Maraknya peredaran benih palsu dengan berbagai modus operandinya, (3) Minimnya jumlah pengusaha penangkaran benih bersertifikat, dan disamping itu (4) Harga benih bersertifikat relatif lebih tinggi bagi masyarakat pemula yang berusaha dibidang perkebunan. Usaha penangkaran benih bersertifikat cukup potensial dalam meningkatkan Pendapatan Asli Daerah (PAD). Penarikan bea retribusi dari kegiatan sertifikasi benih perkebunan selama ini didasarkan atas Surat Keputusan Gubernur Bengkulu nomor 329 tahun 2001. Pengutipan retribusi dari sertifikasi benih bukan merupakan investasi langsung dari masyarakat dan disamping itu berperan untuk menekan peredaran benih ilegitim (palsu), serta mendukung kemudahan masyarakat petani pekebun untuk mencari benih yang berkualitas.
