| Abstract: | Tomat merupakan salah satu dari produk hortikultura yang bersifat mudah
rusak sehingga memiliki umur simpan yang pendek. Teknologi ozonisasi yang
dikombinasikan dengan perlakuan suhu sebagai penanganan pascapanen dapat
memperpanjang umur simpan produk hortikultura. Ozon terlarut dalam air yang
digunakan untuk merendam atau mencuci buah dapat menghambat pertumbuhan
mikroorganisme patogen pada produk pascapanen. Studi ini bertujuan untuk
memperoleh konsentrasi ozon dan suhu penyimpanan yang dapat memperpanjang
umur simpan buah tomat. Percobaan dilaksanakan dengan rancangan petak terbagi
dalam acak lengkap dengan 3 ulangan. Petak utama yaitu perlakuan suhu yang
terdiri atas suhu kamar (23 ± 2 °C) dan suhu rendah (10 ± 1 °C). Petak bagian yaitu
konsentrasi ozon yang terdiri atas kontrol tanpa perendaman, kontrol dengan
perendaman (air biasa), ozon 0.15 ppm direndam 5 dan 10 menit, serta ozon 0.25
ppm direndam 5 dan 10 menit. Peubah yang diamati yaitu susut bobot, perubahan
warna, perhitungan insidensi penyakit (%) dan keparahan penyakit (%), dan total
plate count (TPC). Interaksi ozonisasi dengan perlakuan suhu berpengaruh nyata
terhadap peubah yang diamati. Perlakuan perendaman ozon 0.25 ppm selama 10
menit dan suhu penyimpanan 10 °C merupakan perlakuan terbaik untuk
memperpanjang umur simpan buah tomat. Perpanjangan umur simpan hingga 2
minggu, nampak dari kemampuan mempertahankan warna buah tomat pada kisaran
warna pink dan menghambat perkembangan insidensi dan keparahan penyakit
bercak coklat (Alternaria solani). Tomato is one of the horticulture product which is perishable so that have a short shelf life. Ozonisation technology that combine with temperature treatment as a postharvest treatment can lengthen the shelf life of horticulture produtcs. The ozone dissolved in water to soak and wash fruit can inhibit the growth of pathogen microorganisms in postharvest products. This study aim to find the accurate ozone concentration and storage temperature that can lengthen the shelf life of tomato fruit. This study was conducted using a split plot design in a randomized complete with 3 replications. The main plot is temperature treatment consist of room temperature (23 ± 2 °C) and low temperature (10 ± 1 °C). The sub plot is ozone concentration consist of control without immersion, control with immersion (ordinary water), ozone 0.15 ppm soaked for 5 and 10 minutes, and ozone 0.25 ppm soaked for 5 and 10 minutes. The variables have been observed were weight loss, colour change, disease incidence (%) and disease severity (%) calculation, and total plate count. Interaction of ozonisation and temperature treatment has a significant effect on the observed variables. Ozone immersion treatment 0.25 ppm for 10 minutes and temperature storage 10 °C is the best treatment to lengthen the shelf life of tomato fruit. Extended the shelf life up to 2 weeks, show from the ability to maintain the colour of tomato fruit in stage pink and inhibit the growth of disease incidence and disease severity of brown spot (Alternaria solani). |
