Daerah Batu Busuk, Kelurahan Lambung Bukit Kecamatan Pauh, Kotamadya Padang merupakan salah satu sentra produksi buah durian di kota Padang. Pada saat musim besar atau panen raya (in season) yang bisa berlangsung selama 1 bulan, produksi durian yang dihasilkan dari Batu Busuk diperkirakan mencapai 250–400 ton selama satu musim sedangkan pada musim panen “salek” atau panen kedua diperkirakan mencapai 150–250 ton.Walaupun nama durian Batu Busuk sudah terkenal dan banyak dicari oleh pencinta durian pada saat musim durian, namun demikian hingga kini belum ada upaya untuk mengangkat durian Batu Busuk sebagai buah identitas atau ikon kota Padang selain dari bengkuang. Juga belum ada upaya mengangkat daerah Batu Busuk sendiri sebagai kampung durian yang tidak hanya menghasilkan buah durian yang dijual keluar daerah, namun juga memiliki berbagai produk olahan hasil durian. Upaya yang dilakukan baru sejauh pemberian bantuan bibit durian oleh pemerintah daerah. 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 akan dilakukan pada kegiatan pengabdian pada masyarakat ini menggunakan beberapa metode antara lain penyuluhan dan diskusi grup, demonstrasi dan pelatihan perbanyakan vegetatif melalui teknik sambung baik sambung pucuk (topgrafting)dan sambung matatunas(okulasi) serta demplot pembibitan durian.

Most of the peatlands in Pesisir Selatan, West Sumatra have been converted into agricultural activities. Due to drainage, the peat decomposition process becomes faster. The activity of β-glucosidase is one of the enzymes that can be used as an indicator of the decomposition of organic matter and produces greenhouse gas emissions, likes CO2. Therefore, this study was conducted to identify the activity of β-glucosidase in several land uses in Pesisir Selatan peatlands. Observations were performed in several land-use types consisting of agricultural land (LP), bare land (LT), shrubs (SB), smallholder oil palm plantations (PSr), private company oil palm plantations (PSs), and forests (H). The activity of β-glucosidase was analyzed by using salicin and Na-acetate methods. The results of this study showed that the highest β-glucosidase activity was found in agricultural land use (LP). Based on the land use types, the activity of β-glucosidase follows agricultural land (LP) 3.42 μg.g-1.jam-1 > bare land (LT) 2.26 μg.g-1.jam-1 > shrubs (SB) 1.63 μg.g-1.jam-1 > smallholder oil palm plantations (PSR) 1.31 μg.g-1.jam-1 > private company oil palm plantations (PSs) 1.28 μg.g-1.jam-1 > forest (H) 0.80 μg.g-1.jam-1. Soil characteristic that significantly affects enzyme activity is water content where the higher the water content, the lower the β-glucosidase activity, and vice versa. Based on this study can be concluded that the change in land use from natural land to agricultural land triggers an increase in the activity of enzymes in decomposed peat materials.Key words: β-glucosidase, enzyme, palm plantation, land-use, peatland
