Abstract

Nagari Sungai Talang is one of the villages in Payakumbuh District, Lima Puluh Kota Regency which seeks to cultivate ginger plants. The type of ginger commonly developed by this Innovation farmer group is elephant ginger. This ginger has a rhizome that is larger and fatter, the rhizome segment is more bulging than other varieties of ginger. This type of ginger can be consumed both when you are young and old, both as fresh ginger and processed ginger. One of the obstacles that hinder our farmers from developing organic ginger here is the low production because the supply of nutrients is also low and the attack of pests and diseases is quite high. Therefore, it is necessary to find a treatment that can overcome this problem to increase the production of organic ginger. One of the microorganisms that is widely reported to act as biological agents is from the Plant Growth Promoting Rhizobacteria (PGPR) group or plant growth promoting rhizobacteria. Rhizobacteria have the ability to aggressively colonize the rhizosphere and some types of rhizobacteria are capable of dual roles as biofertilizers and bioprotectants in plants. The purpose of this farmer group empowerment activity is to provide knowledge about the benefits of Rhizobacterial biological agents in triggering the growth and yield of ginger plants in the field as well as plant-disturbing organisms that often attack ginger plants during cultivation, as well as effective control methods through outreach activities and direct counseling in the field. The method used is the method of socialization, counseling and direct discussion with farmer groups. The results obtained from this empowerment activity are that the farmer groups understand the benefits of Rhizobacteria biological agents as a trigger for growth and production of ginger plants, know various plant pest organisms (OPT) and know how to properly control them.

Abstract

Program pengabdian masyarakat ini dilatarbelakangi ketakpahaman masyarakat tentang manfaat dari limbah-limbah pertanian yang ada di sekitar Nagari Gunung Rajo. Limbah dari kegiatan bertani dan beternak tidak ter manfaatkan dengan baik, padahal limbah tersebut dapat digunakan kembali oleh masyarakat. Salah satu teknologi sederhana tepat guna yang dapat dilakukan adalah dengan memanfaatkan limbah dan teknologi rizobakteri sebagai pupuk organik. Salah satu jenis pupuk organik yang terbaik adalah berupa kompos, karena dapat menyediakan unsur hara bagi tanaman dan memperbaiki struktur maupun kesuburan tanah. Adapun bahan-bahan yang digunakan dalam pembuatan rizokompos adalah tumbuhan Tithonia diversifolia, sekam padi, dedak dan pupuk kandang sapi. Dalam proses dekomposisi digunakan Rizobakteri sebagai decomposer dengan cara rizobakteri disiramkan pada bahan kompos, lalu kompos dibalik dan diberi rizobakteri kembali setiap minggu dengan proses pembuatan total 3 minggu. Program ini bertujuan untuk meningkatkan pengetahuan masyarakat tentang pemanfaatan limbah pertanian dan aplikasi rizobakteri indigenos dalam pembuatan kompos. Kegiatan ini telah dilakukan dalam bentuk penyuluhan dan demonstrasi. Kegiatan ini sangat bermanfaat bagi masyarakat khususnya masyarakat Nagari Gunung Rajo. Antusias dan partisipasi aktif dari masyarakat sangat menunjang keberhasilan dari kegiatan ini. Pertumbuhan dan hasil produksi yang terbaik didapatkan pada perlakuan rizokompos dan rizobakteri dibanding diaplikasikan secara tunggal.

Abstract

Cabai merah merupakan sumber pendapatan utama bagi petani di daerah Tanah Datar. Masalah utama yang selalu dihadapi oleh petani cabai di daerah ini adalah serangan hama dan penyakit yang dapat menyebabkan kehilangan hasil yang cukup tinggi. Hingga saat ini, pengendalian hama dan penyakit sayuran masih mengandalkan pestisida sintetik yang telah menimbulkan dampak negatif. Untuk itu, perlu dicari alternatif pengendalian yang dapat mengurangi dampak negatif pestisida tersebut, yaitu menggunakan agens hayati seperti cendawan Beauveria bassiana dan Trichoderma sp.Tujuan dari kegiatan pengabdian kepada masyarakat ini adalah untuk memperkenalkan dan memasyarakatkan pengendalian hama dan penyakit menggunakan agens hayati Beauveria bassiana dan Trichoderma sp. Metode kegiatan pengabdian adalah penyuluhan, pelatihan dan praktek lapangan. Minat petani untuk menggunakan agens hayati terutama Beauveria bassiana dan Trichoderma cukup tinggi dan telah memotivasi mereka untuk mengurangi penggunaan pestisida sintetis. Petani juga telah berhasil memperbanyak agens hayati dan membuat kompos limbah pertanian menggunakan Trichoderma.
