“…Pada serangan berat mengakibatkan daun menjadi mengering dan gugur sebelum waktunya sehingga kualitas dan kuantitas bawang merah menjadi menurun. Seranggan hama ini dapat menyebabkan kehilangan hasil hingga 100% (Pratiwi et al, 2022). Salah satu kendala yang sangat penting dan sering kita jumpai yaitu adanya penyakit bercak ungu yang disebabkan oleh jamur patogen Alternaria porri (Ruswandari et al, 2020).…”

There is a pest of shallots (Allium ascalonicum L.) with the most common cases being onion caterpillars and purple spot which must be controlled to get good yields. This study aims to determine the properties of the stability of the model by examining the stability analysis by determining the model equation, equilibrium point, basic reproduction number, analysis of the equilibrium point by linearization of the Jacobian matrix to obtain eigenvalues and stability properties. The simulation shows the effect of pesticide treatment using the fourth order Runge-Kutta method and the Matlab program. There are two equilibrium points: (1) Point (E0) free of pests and diseases is stable if R0 < 1. (2) Endemic point (E1) is stable if R0 > 1. The simulation shows that the greater the pesticide treatment, the faster the susceptible population and infected decreased, the faster the recovering population has increased.

“…Pada tanaman padi, tanaman refugia mampu menekan keberadaan hama wereng batang coklat [3] dan penggerek batang [4] dengan cara meningkatkan pola kunjungan serangga pada tanaman padi [5], [6]. Kegiatan penanaman tanaman refugia juga telah berhasil menekan serangan hama dan penyakit pada tanaman kentang [7] dan bawang merah [8]. Lebih lanjut bekerjasama dengan kelompok tani untuk penanaman refugia dan melakukan penyuluhan manfaat tanaman refugia bersama penyuluh pertanian setempat.…”

Kegiatan pengabdian masyarakat ini dilakukan dengan tujuan untuk meningkatkan peran Kelompok Wanita Tani (KWT) melalui kegiatan pembibitan atau nursery pada Kebun Bibit Desa (KBD). Kegiatan nursery yang dilakukan oleh Kelompok Wanita Tani dalam pengabdian masyarakat ini adalah pembibitan tanaman refugia (refugia plant nursery). Tanaman refugia merupakan tanaman yang ditanam atau dibudidayakan disekitar tanaman utama sebagai tempat hidup musuh alami. Keberadaan musuh alami sangat bermanfaat menekan serangan hama penyakit pada tanaman utama. Dalam pelaksanaannya pengabdi akan bekerjasama dengan kelompok tani, dinas pertanian, serta penyuluh setempat. Bentuk pengabdian yang dilakukan yaitu sosialisi dan penyuluhan manfaat tanaman refugia serta pelatihan dan pendampingan pembibitan sampai penanaman tanaman refugia. Manfaat dari kegiatan pengabdian ini adalah meningkatkan peran aktif kelompok wanita tani dalam kegiatan usaha tani, mengoptimalisasi kebun bibit desa yang ada, lingkungan persawahan dan jalan desa menjadi lebih indah dengan tanaman refugia, meningkatnya musuh alami sehingga mengurangi serangan hama dan penyakit tanaman utama yaitu padi, mengurangi penggunaan pestisida, dan meningkatkan keseimbangan ekosistem sawah

“…If no control is done, it will have an impact on reducing the productivity of onion farmers' crops. Pest attacks occur at the age of 7-42 days after planting until the tuber maturation phase (Suharti, 2018). This can result in crop failure because the damage caused can reach 57%-100% (Prasetyo, 2016).…”

Spodoptera exigua is the main pest that attacks the onion crop. S.exigua attack can cause crop failure reaching 57%-100%. The use of natural ingredients from plants for vegetable pesticides such as papaya leaves and mahogany leaves containing secondary metabolite compounds: alkaloids, papain, saponins, tannins, terpenoids, flavonoids and steroids that can damage the feeding activity system and damage the pest growth system which eventually the pest will die. This study uses a non-factorial RAL (Completely Randomized Rack) method with 7 treatments M0= Control, M1= Papaya leaf extract 30%, M2= Papaya leaf extract 60%, M3= Mahogany leaf extract 30%, M4= Mahogany leaf extract 60%, M5 = Papaya leaf extract 15% + mahogany leaf extract 15%, M6= Papaya leaf extract 30% + mahogany leaf extract 30%. The highest mortality result is 72.50% with the treatment of 60% papaya extract vegetable pesticide and the lowest is 27.50% with the treatment of 30% mahogany extract vegetable pesticide. The initial symptoms of death of S. exigua caterpillars are characterized by larvae that are less active in moving, moving to the surface of the container, moving away from the feed, convulsing and finally dying. The mortality of S. exigua larvae at 24 JSA killed a total of 14 larvae and increased with each subsequent treatment. The results of the vegetable pesticide test on natural enemies using extracts that produce the highest percentage of mortality on S. exigua is 100%. This indicates that the extract is safe for the survival of natural enemies. Plant-based pesticides papaya leaf extract, mahogany leaves and a combination of papaya and mahogany leaves have an effect on the mortality of S. exigua caterpillars
