Abstract

One of the causes of the low productivity of rice grown on peat soils was the high levels of of toxic phenolic compounds in the soil. Development of tolerant rice varieties is one of strategies to grow rice on peat soils. The aims of this research were to select rice varieties tolerant to peat soils and to study the correlation between the plant phenolic acid content with plant tolerance to peat soil. This research was conducted at the Seed Farm Centre Lubuk Minturun, Padang from February to July 2009. The research consisted of two experiments i.e. in peat soil and in mineral soil. The experiments used a completely randomized design using 21 varieties of rice as treatments which were replicated four times. The results showed that there were nine rice varieties categorized as tolerant to peat soil. These tolerant varieties showed higher stress tolerance index (STI), demonstrated by a high level of phenolic acids (coumaric, syringic, and ferulic) in the plant tissues. The STI value had positive correlation with the content of plant phenolic acids, thus the level of plant phenolic acids can be used as an indicator to determine tolerant rice varieties in peat soils. Keywords: peat soil, phenolic acids, tolerant rice, STI

Abstract

Penelitian ini ditujukan untuk mempelajari perilaku asam fenolat pada tanah gambut danbagaimana kaitannya dengan unsur kalsium dan magnesium. Asam fenolat yang diteliti pada penelitian iniadalah asam hidroksi benzoat dan asam p- kumarat, Sampel yang digunakan tanah gambut dari daerahRimbo Panjang . Km 18 dari kota Pekanbaru.Hasil yang diperoleh dari penelitian ini adalah pemberian fly ash terhadap tanah gambut ternyatadapat menurunkan kandungan asam hidroksi benzoate dari 27,42 ppm ke 0,20 ppm; asam p-kumarat 17,22ppm ke 0,11 ppm serta dapat meningkatkan pH dari 3,5 ke 6,47 , ketersediaan hara kalsium 595,24 ppmke 2569,36 ppm dan magnesium dari 365,05 ppm ke 469,45 ppm pada tanah gambut.Penurunan kandungan asam fenolat sebagai akibat pemberian fly ash dapat meningkatkanketersediaan unsur hara kalsium ( Ca) dan Magnesium.Key word : Gambut, fly ash. Asam fenolat,kalsium, magnesium

Abstract

ABSTRAK: Kampung Batu Busuk Kelurahan Lambung Bukit Kecamatan Pauh merupakan salah satu sentra produksi buah durian di Sumatera Barat.Walaupun nama durian Batu Busuk sudah terkenal dan banyak dicari oleh pencinta durian pada saat musim durian, namun belum ada upaya untuk mengangkat durian Batu Busuk untuk bisa dikenal lebih luas. Langkah awal untuk mengangkat nama durian Batu Busuk adalah membenahi identitas varietas durian Batu Busuk, karena sampai sekarang karakteristik dari durian Batu Busuk yang sesungguhnya tidak jelas.Tanaman yang sudah dikarakterisasi juga perlu diperbanyak agar kedepan, buah yang dihasilkan oleh kelurahan Batu Busuk adalah buah dengan karakter unggul tertentu. Masyarakat atau petani yang menanam durian juga perlu memiliki keahlian memperbanyak durian unggulnya. Penerapan ipteks yang dilakukan pada kegiatan pengabdian pada masyarakat ini menggunakan beberapa metode antara lain penyuluhan, demonstrasi aplikasi dan demplot pembibitan durian. Hasil kegiatan menunjukkan bahwa kegiatan penyuluhan yang dilakukan berhasil meningkatkan pengetahuan masyarakat Batu Busuk mengenai arti penting pendaftaran varietas durian. Kegiatan demplot pembibitan durian dan demonstrasi teknik sambung meningkatkan pengetahuan dan keterampilan masyarakat mengenai propagasi durian. Kata kunci: Durian ungggul, Pendaftaran varietas, Teknologi tepat guna, Teknik sambung Development of Durian Batu Busuak, Lambung Bukit Village, Padang CityABSTRACT: Batu Busuk area, Lambung Bukit Village, Pauh Subdistrict, is one area of the centers of durian fruit production in West Sumatra. Although the Batu Busuk durian is already well-known and is sought after by durian lovers during the durian season, there is no attempt to lift the Batu Busuk durian to be known more widely. The first step to lifting the Batu Busuk durian is to fix the varieties identity of the Batu Busuk durian because until now the characteristics of the real Batu Busuk durian are not clear. Plants that have been characterized also need to be propagated so that in the future, the fruit produced by the Batu Busuk village is a fruit with certain superior characters. The community or farmers who plant durian also need to have the expertise to increase their superior durian. The application of science and technology conducted in community service activities uses several methods including counseling, demonstrations of applicationand demonstration plots of durian nurseries. The results of the activity showed the extension activities conducted succeeded in increasing the knowledge of the Batu Busuk community regarding the importance of registering durian varieties. The activities of the durian nursery demonstration plot and demonstration of connection techniques can increase the knowledge and skills of the community regarding the propagation of durian.Keywords: Superior durian, Varieties registration, Appropriate technology, Connection technique
