Long bean (Vigna sinesis L.) is a horticultural plant that is easy to cultivate. Cultivation of long bean plants certainly has several factors that can reduce production yields such as environmental factors, pest attacks, and diseases. This study aims to determine the pests and diseases that generally attack long bean plants and the symptoms they cause. This study used direct observation method (Systematic sampling) to determine the percentage of pest and disease attacks on long bean plants. From the total number of plants in the location, 5 plant samples were taken to be observed. Based on the pest and disease identification research that has been carried out, it was found that some of the symptoms that arise due to pest/disease attacks on most of the long bean plants were found. Symptoms that appear include damage to flower buds and leaves with holes caused by black ladybugs (Brachyplatys sp.); leaf curl, leaves and stems turn black due to aphids (Aphis craccivora); jagged leaf edges, and holes caused by grasshoppers (Oxya sp.) and lasiocampidae caterpillars; thickening of the leaf veins on young leaves, leaves shrinking caused by Bean Common Mosaic Virus (BCMV); The leaves turn yellow and the bone blanching occurs due to the Mungbean Yellow Mosaic Virus (MYMV).
Pakis merupakan media tanam terbaik untuk anggrek, karena dilindungi maka diperlukan solusi untuk mengurangi atau mengganti media pakis dengan campuran kompos. Pada penelitian ini dipilih kompos kulit kacang tanah dan kompos jerami sebagai campuran media. Selain mengurangi media pokok, kompos juga dapat berfungsi sebagai pupuk. Tujuan dari penelitian ini untuk mengetahui; 1. pengaruh campuran kompos pada media tanam terhadap pertumbuhan seedling anggrek Dendrobium sp 2. jenis kompos dan komposisi campuran, pada media tanam untuk pertumbuhan seedling anggrek Dendrobium sp. Waktu penelitian 2,5 bulan, objek penelitian adalah Dendrobium sp. anggrek berumur 12 bulan, lokasi penelitian di Desa Gabahan, RT 05 RW 12, Jombor Sukoharjo. Rancangan penelitian acak kelompok dengan 5 perlakuan. Perlakuan Penanaman seedling anggrek dengan media pakis dicampur kompos kulit kacang tanah 1/2 bagian (A), media dicampur kompos kulit kacang tanah 1/3 bagian (B), media dicampur kompos jerami 1/2 bagian (C), media dicampur kompos jerami 1/3 bagian (D), dan perlakuan dengan media pakis sebagai kontrol (E). Variabel yang diamati adalah jumlah daun, panjang daun, luas daun, jumlah batang, serta tinggi tanaman yang diukur 12 minggu setelah penanaman. Analisis data menggunakan Uji Varian (Uji ANOVA/Kruskal Wallis) dilanjutkan dengan Uji DMRT atau Uji Median Mood. Pemberian campuran kompos pada media tanam baik kompos kulit kacang tanah maupun kompos jerami berpengaruh terhadap pertumbuhan seedling anggrek Dendrobium sp pada variabel panjang daun dan tinggi tanaman. Sedangkan pada variabel jumlah daun, luas daun dan jumlah batang tidak terdapat pengaruh yang signifikan. Perlakuan campuran kompos B dengan campuran kompos kulit kacang tanah 1/3 bagian memberikan pengaruh paling baik pada variabel pertumbuhan panjang daun, jumlah daun, luas daun, serta jumlah batang. Pengaruh campuran kompos jerami 1/2 maupun 1/3 bagian media terhadap pertumbuhan seedling anggrek kalah bagus dibanding dengan kompos kulit kacang tanah.
