Abstract

Using leaf explants, this research aimed at identifying the type of growth response that can be created and the optimal mix of media for the growth of Cattleya sp orchid. This was an experimental investigation employing the RAL method (completely randomized design) with a combination of 2.4-D (0;1; 2; 3 ppm) and Kinetin  (0;0.3;0.6 ppm) repeated three times. According to the results of this study, the growth regulators 2.4-D and kinetin  were unable to promote the development of all explants. Explants transferred to media containing polyvinylpyrrolidone (PVP) to prevent browning after 12 weeks of observation. Then the results of the study also found the emergence of shoots in the treatment P0 (control), P2 (2,4-D 0 + Kinetin  0.6 ppm), P8 (2,4-D 2 + Kinetin  0.6) and P11 (2.4- D 3 + K 0.6 ppm) in the 3rd week of observation, the appearance of callus at P5 (2.4-D 1 + Kinetin  0.6 ppm) in the 4th week of observation

Abstract

The use of natural pesticides, such as mahogany seed extract, can control crop pests without negative health effects. However, farmers' awareness of its benefits remains low. This study aims to socialize the utilization of mahogany seed extract as a natural pesticide to farmers in Kolam Village, Percut Sei Tuan District, North Sumatra. The activity, involving 30 farmers, was conducted in March 2024 and included socialization, training on production, application, and evaluation of natural pesticide use. The results showed high enthusiasm among farmers, indicating the potential for sustainable application of this natural pesticide in their agricultural practices.ABSTRAKPenggunaan pestisida alami, seperti ekstrak biji mahoni, dapat mengendalikan hama tanaman tanpa dampak negatif bagi kesehatan manusia. Namun, kesadaran petani tentang manfaatnya masih rendah. Penelitian ini bertujuan mensosialisasikan pemanfaatan ekstrak biji mahoni sebagai pestisida alami kepada petani di Desa Kolam, Kecamatan Percut Sei Tuan, Sumatera Utara. Kegiatan yang melibatkan 30 petani ini dilaksanakan pada Maret 2024, mencakup sosialisasi, pelatihan pembuatan, aplikasi, dan evaluasi penggunaan pestisida alami. Hasilnya menunjukkan antusiasme tinggi dari para petani, mengindikasikan potensi penerapan pestisida alami ini secara berkelanjutan dalam praktik pertanian mereka.
