Abstract

INDONESIA:

Kentang (Solanum tuberosum L.) merupakan salah satu pangan utama dunia setelah padi, gandum, dan jagung. Kentang juga termasuk komoditas unggulan hortikultura nasional sebagai bahan pangan alternatif yang dapat menunjang program diversifikasi pangan dan komoditas yang paling berpeluang untuk pengembangan agribisnis dan agroindustri namun, di Indonesia masih mengalami penurunan pada tingkat rata-rata produksi. Kendala utama disebabkan oleh serangan organisme pengganggu tumbuhan (OPT) Nematoda Sista Kuning (NSK) Globodera rostochiensis (Wollenweber). Pertama kali terjadi Maret 2003 di Desa Tulung Rejo, Bumiaji, Kota Batu (Jawa Timur). Pada stadium dorman, nematoda lebih resisten terhadap nematisida. Pengendalian biologi dengan menggunakan bakteri endofit merupakan alternatif pengendalian nematoda parasit tanaman. Tujuan penelitian ini adalah untuk mengetahui pengaruh jenis filtrat bakteri endofit, lama perendaman filtrat bakteri endofit dan interaksi dari kedua variabel tersebut terhadap penetasan telur NSK (G. rostochiensis (Wollenweber)).

Penelitian ini merupakan penelitian eksperimen. Penelitian ini yang dilaksanakan bulan Februari 2012 sampai dengan Maret 2013, di Laboratorium Mikrobiologi dan Laboratorium Optik Jurusan Biologi Fakultas Sains dan Teknologi Universitas Islam Negeri (UIN) Maulana Malik Ibrahim Malang. Teknik analisis data menggunakan program SPSS 17.0. menggunakan uji normalitas, dilanjutkan dengan analisis deskriptif dan regresi.

Hasil penelitian ini menunjukkan bahwa filtrat bakteri endofit tidak memberikan pengaruh terhadap penetasan telur NSK (G. rostochiensis (Wollenweber)). Filtrat bakteri endofit yang digunakan tidak menetaskan telur NSK (G. rostochiensis (Wollenweber)) dengan lama perendaman yang sama, yaitu sampai hari ke-18. Interaksi antar variabel jenis filtrat bakteri endofit dan lama perendaman, keduanya tidak memiliki hubungan, sebab pengaruh yang diberikan oleh variabel yang diuji hanya 5,2%

ENGLISH:

Potato (Solanum tuberosum L.) is the fourth most important food crop after corn, rice and wheat. The potato also includes the flagship national horticulture commodities as alternative feedstocks that can support the food and commodity diversification program the most likely for the development of agribusiness and agro-industries in Indonesia is still experiencing a decrease in the average rate of production. The main barriers are caused by organisms attacking plantsof yellow cyst nematode (YCN) Globodera rostochiensis (Wollenweber). It first took place in March 2003 in the village of Tulung Rejo, Bumiaji, Batu City (East Java). On stadium dorman, nematodes are more resistant to nematisida. Biological control of bacterial endophyte is using alternative control of nematodes parasite of plants. The purpose of this study was to determine the influence of bacterial endophyte filtrate, filtrate prolonged submersion bacterial filtrate endophyte and the interaction of these two variables of hatching eggs of YCN (G. rostochiensis (Wollenweber)).

This research is a research experiment. This research was carried out in February 2012 to March 2013, in the laboratory of Microbiology and Optical Laboratory of Biology Department of the Faculty of Science and Technology Maulana Malik Ibrahim State Islamic University (UIN) of Malang. Technique of using SPSS 17.0 data analysis program. Using the test of normality, continued with a descriptive analysis and regression.

The results of this research show that all six isolates of bacterial endophyte filtrate provides no effect on hatching eggs of YCN (G. rostochiensis (Wollenweber)). Bacterial endophyte filtrate with long soaking up the 18th-day, not hatching eggs of YCN (G. rostochiensis (Wollenweber)). Interactions that occur between these two variables being tested is not the only factor that hampered hatching eggs, the influence exerted by both the variables tested, they have no relationship, because of the influence exerted by the variables tested only 5,2%.

The results of this research show that the bacterial filtrate endophyte provides no effect on hatching eggs of YCN (G. rostochiensis (Wollenweber)). Bacterial endophyte filtrate with long soaking up the 18th day, not hatching eggs of YCN (G. rostochiensis (Wollenweber)). Interactions between variable types of bacterial endophyte filtrate and long soaking, they have no relationship, because of the influence exerted by the variables tested only 5,2%.
