This study aims to analyze the deterioration of the quality of the chayote during storage using several packaging methods. The research method was carried out experimentally and the data were processed descriptively which consisted of three treatments, namely: vacuum packed, without vacuum, and open. Each treatment was carried out 3 (three) times with each weight of 250 grams. Research shows that minimally processed chayote which is vacuum packed and stored at a temperature range of 5oC - 9.6oC can last for 12 days, experiencing a weight loss of 0.90%. The color changed from Faded Yellow to Gray Yellow. The texture becomes soft with a hardness value of 8.80 N. The water content changes from 91.98% to 94.70%.In conclusion, the storage life of vacuum packed minimally processed chayote could be prolonged up to 12 days at 5oC – 9,6oC, grey-yellow in color, texture softened, and weight loss as much as 0.90%. Keywords: Chayote, minimally processed, vacuum packed.

This study aimed to obtain the concentration and duration of immersion Giberalin type GA 3 the most effective way to extend the shelf life of gladiolus flowers, and to get the type of packaging and the right temperature in prolonging the shelf life of gladiolus flowers to prolong shelf life. Descriptive method was used in two experiments. The first experiment was GA3 concentration and immersion time on the shelf life of gladiolus flowers. The second experiment was the type of packaging and cold temperatures on the shelf life of gladiolus flowers. The result of first experiment showed that gladiolus flowers soaked at a concentration of 250 ppm GA3 and 1 hour immersion time gives had the lowest value. CO2 production was ranged from mlCO2/kg.hours 18:43 to 33.30 mlCO2/kg.hours. Severe shrinkage rates in day two ,four and six were 27.92%, 36.31% and 40.27% respectively. The degree of gladiolus flowers bloom in the day two was 42.85% and degree of on day four was 33.63%. The results of second experiment showed that gladiolus flowers packed in polypropylene plastic storage temperature of 5 0 C for 12 days resulted the lowest value. CO2 production were ranged from 8.68 mlCO2/kg.hours -15:10 mlCO2/kg.hours. The severe shrinkage in first day was 1 27.29%. The degree of blooming in the 8 th day was 9.63%. Degree of wilting during 12 days storage was 0%. ABSTRAKPenelitian ini bertujuan mendapatkan konsentrasi dan lama perendaman Giberalin jenis GA3 yang paling efektif untuk memperpanjang masa simpan bunga gladiol, dan mendapatkan jenis kemasan dan suhu yang tepat dalam memperpanjang masa simpan bunga gladiol untuk memperpanjang masa simpan. Penelitian ini menggunakan metode deskriptif, dalam 2 eksperimen yaitu 1) Kajian konsentrasi GA3 dan lama perendaman terhadap masa simpan bunga gladiol 2) Kajian jenis kemasan dan suhu dingin terhadap masa simpan bunga gladiol Hasil penelitian tahap 1 menunjukkan bunga gladiol yang direndam pada konsentrasi GA3 250 ppm dan lama perendaman 1 jam memberikan nilai yang paling rendah. Produksi CO2 berkisar 18.43 mlCO2/kg.jam -33.30 mlCO2/kg.jam, susut berat bunga di hari ke-2 yaitu 27.92%, hari ke-4 sebesar 36.31% dan hari ke-6 40.27% sebesar. Derajat mekar bunga gladiol di hari ke-2 sebesar 42.85% dan derajat layu dihari ke 4 sebesar 33.63%. Hasil penelitian tahap 2 menunjukkan bunga gladiol yang dikemas plastik polipropilen pada suhu penyimpanan 5 o C selama 12 hari memberikan nilai yang paling rendah. Produksi CO2 berkisar 8.68 mlCO2/kg.jam -15.10 mlCO2/kg.jam, susut berat di hari ke-1 27.29%, derajat mekar di hari ke-8 sebesar 9.63% dan derajat layu 0% selama penyimpanan 12 hari.
