Abstract
Penelitian ini bertujuan menduga umur simpan kemplang microwave dalam kemasan PP (polypropylene) menggunakan perhitungan kadar air kritis dilaksanakan di Laboratorium Pengolahan Hasil Pertanian, Laboratorium Kimia Hasil Pertanian Jurusan Teknologi Pertanian, Fakultas Pertanian, Universitas Sriwijaya, pada bulan Mei 2020 sampai April 2021. Pendugaan umur simpan didekati dengan metode Kadar Air Kritis. Kemplang yang digunakan ada empat jenis yaitu keriting panjang, keriting bulat, bulat kecil dan bulat besar. Parameter yang diamati adalah perhitungan kadar air awal (Mo), kadar air kritis (Mc), kadar air keseimbangan (Me), konstanta permeabilitas uap air kemasan (k/x), Tekanan uap jenuh (Po), berat padatan per kemasan (Ws), luas kemasan (A) serta parameter pendukung kadar lemak dan peroksida. Hasil penelitian menunjukan bahwa kemplang bulat besar memiliki pendugaan umur simpan 22 hari pada RH 75%, 20 hari padar RH 80% dan 17 hari pada RH 90%. Kemplang keriting panjang memiliki pendugaan umur simpan 18 hari pada RH 75%, 16 hari pada RH 80% dan 13 hari pada RH 90%. Kemplang keriting bulat memiliki pendugaan umur simpan 15 hari pada RH 75%, 13 hari pada RH 80% dan 11 hari pada RH 90%. Kemplang bulat kecil memiliki pendugaan umur simpan 15 hari pada RH 75%, 13 hari pada RH 80% dan 11 hari pada RH 90%. Kadar lemak kemplang ikan microwave sebesar 0,16% dan kadar peroksidanya tidak terdeteksi.
