Nanas merupakan salah satu komoditas ekspor utama di Indonesia. Dari total ekspor nanas pada tahun 2017, sebanyak 95% nanas di ekspor dalam bentuk olahan dan sisanya dalam bentuk segar. Hal ini disebabkan oleh kadar air buah yang tinggi sehingga, buah bersifat perishable (mudah rusak). Salah satu upaya yang dapat dilakukan adalah dengan aplikasi coating berbasis pati. Penelitian ini bertujuan untuk 1)  Mengetahui pengaruh aplikasi coating berbasis pati ganyong, kentang, dan ubi jalar terhadap karakteristik fisik dan kimia buah nanas selama penyimpanan; 2) Mengetahui pengaruh aplikasi coating metode spraying dengan ukuran nozzle yang berbeda terhadap karakteristik fisik dan kimia buah nanas selama penyimpanan; 3) Mengetahui kombinasi perlakuan ukuran nozzle sprayer dan jenis pati terpilih terhadap kualitas buah nanas selama penyimpanan. Penelitian ini merupakan jenis penelitian eksperimentasl Rancangan Acak Lengkap (RAL) faktorial. Faktor yang diteliti adalah jenis bahan coating (P) dengan 3 jenis yaitu coating berbahan pati ganyong (P1), coating berbahan pati kentang (P2), dan coating berbahan pati ubi jalar (P3); ukuran nozzle sprayer (N) dengan 3 jenis yaitu ukuran nozzle sprayer 0,6 mm (N1), ukuran nozzle sprayer 1 mm (N2), ukuran nozzle sprayer 1,5 mm (N3). Hasil uji F menunjukkan bahwa secara keseluruhan interaksi kedua faktor berpengaruh sangat nyata terhadap kadar air, vitamin C, total padatan terlarut, tingkat kekerasan, da tingkat kecerahan pada buah nanas.

Pineapple has becoming one of major commodity in Indonesia. Based on pineapple export data in 2017, as much as 95% of pineapple exported in a processed type of form and the rest are most likely exported in a fresh form of fruit. This is caused mainly by how high does water of one pineapple can content, therefore pineapple tend to be characterized as perishable. One of the way to better managed the post-harvesting is by the applicational concept of starch-based coating. The purpose of this research is: 1) To determine the application of canna, potato, and sweet-potato’s starch-based coatings to the physical as well as chemical characteristics of pineapple during storagement; 2) To understand the application of spraying method with different nozzle sizes may affect the physical and also chemical characteristics of pineapple during storagement; 3) To study the combination of the nozzle sprayer size setting and which type of the selected-starch on the quality of pineapple during storagement. This research is an experimental type of factorial research based on Completely Randomized Design. The determining factor is the type of coating material (P) with 3 types, namely canary starch (P1), potato starch (P2), sweet-potato starch (P3); the size of the sprayer nozzle 0,6 mm (N1), the size of the sprayer nozzle 1 mm (N2), the size of the sprayer nozzle 1,5 mm (N3). The results of the F test showed that overall the interaction of two factors had a very significant effect on water content, vitamin C, total  dissolved solids (TDS), hardness level and the brightness level.
