      Abstract
      Filtrasi merupakan suatu metode umum dalam produksi produk-produk minuman. Pemakaian filter katrid (CF) di PT XYZ tidak dapat dipakai ulang, karena bagian gasket yang rusak oleh penutup yang tajam. Tujuan penelitian ini adalah mengevaluasi kondisi filter agar dapat dipakai kembali dan produk akhir memenuhi standar kualitas. Tahap pra-percobaan digunakan CF mini merek B. Berdasarkan evaluasi sensori, hasil pre-percobaan dapat digunakan CF merek A 1 mikron dan merek B 20 mikron. Kedua CF tersebut digunakan dalam tahap percobaan pertama. Tekanan diferensial dari kedua filter lebih rendah dari tekanan maksimum (< 2,5 bar). Kekeruhan, pH dan °Brix tidak dipengaruhi dari kedua filtrasi katrid atau kedua tahap percobaan. Setelah percobaan pertama, katrid merek B disanitasi dan disimpan. Permukaan filter tersebut ditemukan pertumbuhan kapang karena pengeringan filter yang belum merata saat disimpan. Setelah disanitasi dan disimpan pada lemari penyimpanan filter, pertumbuhan jamur tidak ditemukan pada percobaan kedua. Uji stabilitas dari produk akhir sampai 6 minggu hampir seluruhnya memenuhi kualitas untuk evaluasi sensori, uji kimia, dan mikrobiologi.
       
      Filtration is a general method in beverages production. Cartridge filter (CF) usage at PT XYZ is not reusable, because the gasket is damaged by the sharp cap. The objectives of this research are evaluating filter conditions that can be reusable, and the final isotonic drink products meet the quality standard. Pre-trial step used mini CF brand B. The pre-trial outcome is to utilize CF 1 micron of brand A and 20 microns of brand B based on sensory evaluation. In the first experiment, both CFs were used. When applied in product filtering or sanitizing-in-place (SIP), the pressure drop of both filters is less than the maximum pressure (< 2,5 bar). Turbidity, pH and Brix degree are not significantly affected by both cartridge filtration or both trials. After the first trial, the brand B cartridge was sanitized and stored. Mold growth was discovered on the filter's surface as a result of the filter's uneven drying when it was stored. After being cleaned and placed in filter storage and vacuum packaged in the second trial, no mould growth was observed on the cartridge filters. Stability test of the final products until 6 weeks has almost fulfilled of quality for the sensory evaluation, chemistry, and microbiology test.
