Abstract

ABSTRAK

Selada merah merupakan sayuran daun yang kaya serat dan nutrisi, namun sangat mudah rusak selama penyimpanan. Maka dari itu diperlukan metode penangan pascapanen yang efektif untuk mempertahankan mutu selama penyimpanan sayur selada merah. Penelitian ini bertujuan untuk menganalisis pengaruh ketebalan plastik LDPE terhadap mutu selada merah selama penyimpanan suhu rendah. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan lima perlakuan ketebalan plastik LDPE: tanpa kemasan (kontrol), 0,2 mm, 0,3 mm, 0,4 mm, dan 0,5 mm. Parameter yang diamati meliputi susut bobot, tekstur, warna (ΔE dan chroma), serta uji organoleptik kesegaran. Hasil penelitian menunjukkan bahwa perlakuan S3 (0,4 mm) dan S4 (0,5 mm) paling efektif dalam menekan susut bobot, masing-masing mencapai hanya 4,79% dan 3,04% pada hari ke-12, jauh lebih rendah dibanding kontrol yang mencapai 55,22%. Nilai tekstur tertinggi pada hari ke-6 tercatat pada S3 sebesar 140,94 N, sedangkan nilai organoleptik kesegaran terbaik juga diperoleh pada S3 (4,31). Meskipun tidak semua parameter menunjukkan perbedaan nyata secara statistik, terdapat tren bahwa peningkatan ketebalan plastik LDPE mampu memperlambat penurunan mutu secara fisik maupun sensori. Berdasarkan hasil tersebut penggunaan plastik LDPE dengan ketebalan 0,04–0,05 mm menjadi strategi pengemasan yang optimal untuk memperpanjang umur simpan dan menjaga mutu selada merah selama penyimpanan suhu rendah hingga 12 hari.

ABSTRACK

Red lettuce is a leafy vegetable rich in fiber and nutrients, but is highly perishable during storage. Therefore, effective post-harvest handling methods are needed to maintain the quality during storage of red lettuce. This study aims to analyze the effect of LDPE plastic thickness on the quality of red lettuce during low-temperature storage. This study used a Randomized Block Design (RBD) with five LDPE plastic thickness treatments: without packaging (control), 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm. The parameters observed included weight loss, texture, color (ΔE and chroma), and organoleptic freshness test. The results showed that treatments S3 (0.4 mm) and S4 (0.5 mm) were the most effective in suppressing weight loss, reaching only 4.79% and 3.04% respectively on the 12th day, much lower than the control which reached 55.22%. The highest texture value on day 6 was recorded at S3 at 140.94 N, while the best organoleptic freshness value was also obtained at S3 (4.31). Although not all parameters showed statistically significant differences, there was a trend that increasing the thickness of LDPE plastic was able to slow down the decline in physical and sensory quality. Based on these results, the use of LDPE plastic with a thickness of 0.04–0.05 mm is the optimal packaging strategy to extend the shelf life and maintain the quality of red lettuce during low-temperature storage for up to 12 days.
