    Pagaralam is a city in South Sumatra Province with five districts: North Dempo, Central Dempo, South Dempo, North Pagaralam and South Pagaralam. The main commodity is coffee. Coffee cultivation has a major problem, namely the attack of fruit and branch borer pests because it can reduce the quality and productivity of coffee. This study was to determine the level of attack by fruit borer and branch borer in the Dempo Tengah sub-district. Coffee farmers in Pagaralam use monoculture and polyculture cultivation systems. This field practice method is observation, observation in this study, and interviews with coffee farmers. The results showed that the attack of young coffee berry borer pests can cause the fruit to wither and fall off, while ripe fruit has holes in its seeds. Branch borer attacks cause branches to wither and dry. The highest percentage of fruit and branch borer attacks on coffee plants was found in young mixed-aged coffee plantations. In conclusion, fruit borer and coffee branch borer are more susceptible to attacking coffee at a young age, because young coffee plants have soft plant organs. Lush shade creates high humidity and low temperatures, which can make it easier for pests to breed

    Organisme penganggu tanaman (OPT) merupakan semua makhluk hidup yang dapat menimbulkan kerugian tanaman. OPT tersebut terdiri dari hama, penyakit dan gulma. Semua jenis organisme pengganggu tanaman yang dapat menimbulkan kerusakan fisik yang dianggap merugikan dan tidak diinginkan kehadirannya dalam kegiatan bercocok tanam. Hama yang menyerang tanaman terdiri dari serangga, tungau, vertebrata hama dan hewan lainnya. Serangga-serangga hama menyerang tanaman dapat menimbulkan kerusakan baik secara kualitas maupun kuantitas. Hama, penyakit dan gulma merupakan organisme yang merusak tanaman pada lahan petani yang dapat menimbulkan kerugian secara ekonomis. Serangan OPT pada tanaman dari benih sampai pascpanen. Serangan serangga hama ini dapat mengakibatkan penurunan produksi tanaman dan gagal panen. Pengendalian yang sering dilakukan oleh petani dalam mengurangi serangan hama dan penyakit belum ramah lingkungan. Pengendalian di lapangan perlu dilakukan pemahaman terhadap pengendalian yang ramah lingkungan dan tidak menimbulkan residu pada produk pertani. Karena dalam kondisi masih pandemic petani harus berhati-hati dalam melakukan pengendalian terhadap OPT dilapangan. Tujuan pengabdian untuk memdapatkan metode pengelolaan hama dan penyakit terpadu pada tanaman sayuran dalam masa pandemi covid-19 untuk ketahanan pangan. Untuk memberikan informasi mengenai pengendalian yang ramah lingkungan. Metode dalam pengabdian ini dengan cara mendatangi lahan-lahan petani kemudian melakukan penyuluhan mengenai hama, penyakit dan gulma serta melakukan penyuluhan tentang pengendalian yang ramah lingkungan. Berdasarkan hasil penyuluhan terhadap petani tanaman sayuran dalam melakukan pengendalian semuanya menggunakan pestisida sintetik. Petani tidak mengetahui tentang pengendalian yang ramah lingkungan mayoritas petani masih belum mengetahui tentang pengendalian tersebut. Kemudian dilakukan penjelasan pengendalian yang ramah lingkungan seperti, musuh alami dan pestisida botani. Kemudian dilakukan evaluasi setelah penyuluhan petani sudah bisa membedakan musuh alami yang tergolong predator dan parasitoid. Petani juga dapat membedakan serangga predator dan serangga hama.
