Abstract

Rapid population growth has led to greater nutritional needs and increased market demand, but this has also been accompanied by a decline in food production due to land conversion. This study aims to analyze the impact of crop variety on the growth and yield of lettuce, as well as the impact of AB mix concentration on the growth and yield of lettuce in a Nutrient Film Technique (NFT) hydroponic system. This study employs a nested design with two variables: variety and AB mix concentration. The variables studied in this research include AB mix concentration and lettuce crop variety, each with three replications. The AB mix concentrations applied were 800 ppm, 1,000 ppm, 1,200 ppm, and 1,400 ppm. The lettuce varieties used were General, Georgia, and Kanita 19. The results showed significant differences in all parameters between lettuce varieties, except for the weight of the heads. The Georgia variety showed the best suitability at a concentration of 1,000 ppm, while the General variety was suitable at a concentration of 1,200 ppm. The Georgia variety recorded the highest results in terms of leaf count and production compared to the General and Kanita 19 varieties.

Abstract

Pisang tergolong dalam buah unggulan yang bersifat klimakterik dan mudah rusak sehingga membutuhkan penanganan pascapanen yang tepat terutama pada pemanenan dan penyimpanan. Padatan yang terlarut, kadar asam dan warna dapat menjadi indikator penentu kualitas buah pisang secara kimia dan fisik. Penelitian ini bertujuan untuk mengetahui nilai Total Padatan Terlarut (TPT), Asam Titrasi Total (ATT) serta warna L, *a dan *b pada buah pisang Mas Kirana dengan umur panen dan teknik penyimpanan yang berbeda. Penelitian dilakukan menggunakan Rancangan Acak Lengkap (RAL) dua faktor dengan 4 ulangan. Faktor 1 adalah umur panen 40 dan 57 Hari Setelah Antesis (HSA). Faktor 2 adalah teknik penyimpanan tanpa box kardus, box kardus tanpa KMnO4 dan box kardus dengan KMnO4. Data yang diperoleh dianalisis menggunakan Analysis of Varians (ANOVA) dan dilanjutkan dengan Uji Duncan’s Multiple Range Test (DMRT) pada selang kepercayaan ɑ = 5%. Hasil penelitian menunjukkan bahwa umur panen memberikan pengaruh yang nyata  pada TPT dan warna kecuali nilai ATT dan warna *a pada hari ke-5 penyimpanan. Teknik penyimpanan memberikan pengaruh yang nyata pada TPT , ATT dan warna buah pisang pada hari ke-3 penyimpanan. Umur panen dan teknik penyimpanan tidak memberikan pengaruh yang nyata terhadap TPT, ATT dan warna pada hari ke-5 penyimpanan.
