Abstract

Kegiatan  IbM  ini  dilakukan  untuk  mengatasi  masalah  penggerek  batang  padi (PBP);   meningkatkan pengetahuan, keterampilan dan kemampuan manajerial kelompok tani  Payo  Kering  I  dan  Kelompok  Tani  Payo  Kering  II  tentang  pengendalikan  PBP. Kegitan  ini  dilaksanakan  di  desa  Pasar  Terusan  Kecamatan  Muaro  Bulian  Kabupaten Batang Hari selama 6 bulan. Kegiatan dilaksanakan dengan penerapan metode androgogy dan partisipatory learning and action (PLA). Kegiatan yang dilaksanakan adalah pelatihan pengendalian PBP dan penerapan teknologi dan manajemen pengelolaan PBP. Evaluasi kegiatan IbM dilakukan dengan penilaian pengetahuan, keterampilan dan kemampuan manajerial kelompok sasaran tentang pengendalian PBP, serta keberasilan penerapan pengendalian PBP padi.  Metode evaluasi dilakukan dengan penyebaran questioner di awal dan   diakhir   kegiatan,   kemudian   dianalisis   secara   diskriptif.   Hasil   kegiatan   IbM menunjukan bahwa;  meningkatnya pengetahuan, keterampilan dan kemampuan manajerial petani tentang pengendalian PBP; masalah PBP pada kelompok tani Payo Kering   I dan Payo Kering II  sudah dapat dikendalikan dengan efektif.  Penyuluhan dan bimbingan teknis kepada petani perlu terus dilakukan untuk menumbuhkan kerjasama dalam kelompok dalam sekala luas dan meningkatkan efektifitas dan efisiensi pengelolaan PBP.  Disamping itu perlu dilakukan pembinaan penerapan pengelolaan hama terpadu (PHT) pada tanaman padi secara menyeluruh.   Kata kunci: pengendalain,  PBP, andogogy, PLA

Abstract

The research was conducted to analyze the diversity, dispersal and domination of the egg parasitoid species of the yellow rice stem borer Scirpophaga incertulas Walker on several land typologies in Jambi Province.  The study was conducted by survey method, from December 2010 until June 2011.  Samples of egg parasitoids of S. incertulas were collected by baiting parasitoids with eggs of S. incertulas.  The results of the research showed that there were three spesies of the egg parasitoids of S. incertulas found in Jambi Province, the most dominant was Telenomus rowani Gahan, followed by Trichogramma japonicum Ashmead and Tetrastichus schoenobii Ferriere. T. rowani and T. japonicum were found in all wetland ecosystems in Jambi Province (tidal swamp, swampy area, rainfed lowland, lowland technical irrigation, and upland technical irrigation), while T. schoenobii was found only in tidal swamp, swampy area, and lowland technical irrigation.  The highest species diversity of egg parasitoid of S. incertulas was found on tidal swamp (Shannon index 1.047), followed by swampy area, lowland technical irrigation, rainfed and upland technical irrigation area.  The average of proportion of egg masses parasitized by T. rowani, T. japonicum and T. Schoenobii were 22.58, 6.18 and 2.68% respectively. The average of individual eggs parasitized by T. rowani, T. schoenobii, and T. japnicum were 8.41, 1.67 and 1.47%   respectively.

Abstract

Diversity, domination, and distribution of rice stem borer species and its damage in various land typologies in Jambi Province.  The research was conducted to analyze the diversity, domination, species distribution of rice stem borers (RSB) and its damage on various land typologies in Jambi Province.  The research was carried out using survey method, from December 2010 until June 2011.  Samples of RSB were collected from tidal swamp in Tanjung Jabung Timur District, swampy area in Muaro Jambi District, rainfed lowland in Sarolangun District, irrigated lowland in Merangin District, and irrigated upland in Kerinci District and Sungai Penuh District.  The results showed that there were five spesies of  RSB found in Jambi Province.  Scirpophaga  incertulas Walker (yellow stem borer) was the most dominant of RSB, followed by Sesamia inferens Walker (pink stem borer), Chilo suppressalis Walker (striped stem borer), Chilo polychrysus Meyrick (dark-headed stem borer), and Scirpophaga innotata Walker (white stem borer).  The distribution of S. incertulas, S. inferens, C. suppressalis and C. polychrysus were in all of rice field in Jambi Province, but that of S. innotata was limited over tidal swamp and  rainfield  lowland area. The RSB damage rate was lower than economic thereshold.
