%T EFEK KD-112 DAN PLASTIC WRAPPING TERHADAP MUTU DAN  MASA SIMPAN BUAH PEPAYA ‘CALIFORNIA’
%U http://digilib.unila.ac.id/25611/
%X Pepaya ‘California’ merupakan buah klimakterik. Setelah panen buah pepaya  ‘California’ masih melakukan proses metabolisme, antara lain respirasi dan  transpirasi. Selain itu juga, buah pepaya ‘California’ ini tanggap terhadap gas  etilen baik etilen dari luar maupun etilen yang dihasilkan oleh buah  pepaya‘Caifornia’. Pengaplikasian pelapis buah KD-112 dan plastic wrapping  merupakan salah satu cara untuk meningkatkan masa simpan dan memperlambat  penurunan mutu buah dengan menekan proses fisiologis yang terjadi di dalam  buah.  Penelitian ini bertujuan untuk mempelajari perubahan mutu buah pepaya  ‘California’ selama masa simpan sebagai tanggapan dari aplikasi (1) KD-112, (2)  plastic wrapping, dan (3) kombinasi pelapis buah KD-112 dan plastic wrapping.  Peneilitian ini dilaksanakan di Laboratorium Pascapanen Hortikultura, Jurusan  Agroteknologi, Fakultas Pertanian, Universitas Lampung. Penelitian  iv  dilaksanakan pada Juli hingga Agustus 2015. Penelitian ini menggunakan  Rancangan Teracak Sempurna (RTS), dengan enam kombinasi perlakuan, yaitu  kombinasi dari pelapis buah KD-112 (0, 7, dan 14%) dengan plastic wrapping  (tanpa dan dengan satu lapis plastic wrapping). Kombinasi masing-masing  perlakuan diulang sebanyak tiga kali sehingga jumlah satuan percobaannya adalah  18 satuan percobaan.  Hasil penelitian menunjukkan bahwa (1) aplikasi KD 112 14% mampu  memperpanjang masa simpan buah 3,66 hari lebih lama dibandingkan tanpa  aplikasi KD 112, walaupun tidak mempengaruhi mutu buah, (2) aplikasi plastic  wrapping mampu memperpanjang masa simpan 8,44 hari lebih lama dan menekan  susut bobot dan pelunakan buah namun tidak mempengaruhi mutu kimia buah  dibandingkan tanpa aplikasi plastic wrapping, dan (3) kombinasi perlakuan KD-  112 14% dan plastic wrapping paling efektif dalam mempertahankan mutu buah  pepaya ‘California’ hingga 19 hari simpan.

After harvest papaya 'California' is still in  the process of metabolism, such as respiration and transpiration. In addition,  papaya fruit 'California' is responsive to both ethylene gases from outside and  ethylene produced by pepaya fruits 'California '. An application of KD-112 is a  ways to increase the shelf-life and to slow fruit detioration by lowering the  processes.  This research was aimed at studying the changes in the qualities of papaya  'California' during storage due to the application of (1) KD-112, (2) plastic  wrapping, and (3) combinations of fruit coatings KD-112 and plastic wrapping.  The research was conducted in the Laboratory of Horticultural Postharvest,  Department of Agrotechnology, Faculty of Agriculture, University of Lampung.  The research was conducted in July to August 2015. Treatments were arranged in  a completely randomized design, with six treatment combinations of fruit coatings  KD-112 (0, 7, and 14%) and the plastic wrapping  ii  (without and with a layer of plastic wrapping). The combination of each treatment  was repeated three times so that the number of units of the experiments was 18  units.  The results showed that (1) the application of KD 112 14% was able to extend the  fruit shelf-life by 3.66 days longer than without the application of KD 112,  although it did not affect the fruit quality, (2) the application of plastic wrapping  was able to extend the fruit shelf-life by 8.44 days longer and to supress fruit  weight loss and fruit softening, but did not affect the chemical qualities of the fruit  compared to control, and (3) the combination application of KD-112 14% and  plastic wrapping was the best treatment in maintaining the qualities of papaya  fruit 'California' up to 19 days storage.
