Produktivitas cabai besar di Provinsi Lampung menurun pada tahun 2018 sebesar 24,7%, dari 88,23 kuintal/ha pada tahun 2017 menurun menjadi 66,41 kuintal/ha pada tahun 2018. Hal tersebut salah satunya disebabkan karena kandungan C-organik tanah yang rendah dan tingginya kerontokan bunga cabai. Limbah baglog jamur merupakan bahan yang potensial digunakan sebagai bahan pembenah tanah karena memiliki sifat porous, sehingga mudah menyerap dan menyimpan air, serta mengalirkan air dalam jumlah yang banyak dan mengandung nutrisi untuk tanaman. Untuk mengurangi serangan kerontokan bunga cabai dapat digunakan sungkup plastik berbentuk melengkung yang dapat menahan jatuhnya air hujan secara langsung pada tanaman dan mengoptimalkan penggunaan pestisida dan pupuk daun. Penelitian ini dilaksanakan dengan tujuan mengkaji pengaruh pemberian limbah baglog dan sungkup plastik terhadap pertumbuhan dan hasil cabai, dan mengkaji pengaruh interaksi antara pemberian limbah baglog dan sungkup plastik terhadap pertumbuhan dan hasil cabai. Penelitian ini telah dilaksanakan di lahan praktik hortikultura Politeknik Negeri Lampung, Bandar Lampung. Waktu penelitian dimulai bulan Juli sampai Oktober 2020. Penelitian ini merupakan percobaan faktorial 3 x 2 dengan menggunakan Rancangan Acak Kelompok (RAK) dengan tiga ulangan. Faktor pertama yang dicoba yaitu dosis limbah baglog yang terdiri dari 0 (kontrol), 20 ton/ha dan 40 ton/ha. Faktor kedua adalah penggunaan sungkup plastik yang terdiri dari tanpa sungkup (kontrol) dan pemberian sungkup plastik. Data yang diperoleh dianalisis dengan menggunakan uji F, jika nyata dilanjutkan dengan Uji BNJ pada taraf 5%. Hasil penelitian menunjukkan pemberian limbah baglog jamur meningkatkan tinggi tanaman, jumlah cabang dan bobot buah cabai per petak. Dosis limbah baglog 40 ton/ha memberikan hasil terbaik pada jumlah cabang dan bobot buah cabai per petak. Penggunaan sungkup plastik tidak berpengaruh terhadap pertumbuhan dan hasil cabai, dan tidak terjadi interaksi antara pemberian limbah baglog jamur dengan penggunaan sungkup plastik terhadap semua variabel pengamatan.

Curly red chilies are one of the horticultural products that have the potential to be developed because they have high economic value, however the production of curly red chilies in Lampung Province has continued to decline in the last 4 years. One way to increase production value is to increase soil fertility by increasing fertilization. Fertilization is carried out to replace nutrients lost due to rainwater by using fertilizer containing the elements N, P and K, one of which is KNO3 and KH2PO4 fertilizer. The aim of this research is to find out which combination of KNO3 and KH2PO4 is better and to find out whether the single application of KNO3 and KH2PO4 is good for the growth and yield of curly red chili plants. The research used a factorial randomized block design consisting of 2 factors. The first factor is the concentration of KNO3 fertilizer, with 3 levels, namely 3; 4; 5g/l. The second factor is the concentration of KH2PO4 Fertilizer, with 3 levels of 3,5; 4,5; 5,5g/l. Each treatment was repeated 3 times, so there were 9 treatment combinations and 27 experimental units. The variables observed were plant height, stem diameter, number of shoots, fruit weight per plant, number of fruit per plant and root length. Potassium nitrate (KNO3) fertilizer treatment with a concentration of 5 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth in plant height. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth including the number of branches and stem diameter. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 4,5 g/l had a significant effect on plant yields including the number of fruit/plants and the weight of the fruit/plant.
