Sampel yang digunakan dalam penelitian ini adalah beras putih AA, kukubalam, IR-64, Cap Pocy. Penelitian ini dilakukan dengan dua tahapan, tahap pertama dimulai dengan penyiapan sampel beras yang diperoleh dari berbagai jenis beras yang beredar di sekitar kota Medan, kemudian dihaluskan sehingga menjadi tepung beras. Tahap kedua dilakukan proses penanakan pada beras, setelah tanak kemudian dihaluskan kembali. Dilakukan analisa kadar arsen secara kuantitatif pada kedua jenis sampel tersebut dengan menggunakan alat spektrofotometer serapan atom pada panjang gelombang 193,7 nm. Berdasarkan hasil penelitian maka diperoleh kadar arsen tertinggi ditemukan pada beras merek AA yaitu 0,1293 mg/kg dan terendah pada beras Cap Pocy yaitu 0,0878 mg/kg. Penurunan kadar arsen pada beras AA yang tertinggi ditanak dengan menggunakan air RO yaitu 26,52 % dibandingkan menggunakan air keran, yaitu 19,52 %.","PeriodicalId":336139,"journal":{"name":"Jurnal Riset Teknologi Pangan Dan Hasil Pertanian (RETIPA)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129162327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Faktor pertama adalah konsentrasi ekstrak andaliman kode K yang terdiri dari 5 taraf yaitu: K0 = 0 ppm, K1 = 200 ppm, K2 = 400 ppm, K3 = 600 ppm, KBHT = 200 ppm (wt / vol). Faktor kedua adalah lama penyimpanan (L), dengan 4 taraf yaitu: L1 = 0 hari, L2 = 7 hari, L3 = 14 hari, L4 = 21 hari. Analisis data dilakukan dengan menggunakan uji LSR (Least Significant Ranges). Hasil penelitian menunjukkan bahwa ekstrak andaliman berpengaruh nyata terhadap asam lemak bebas, bilangan peroksida dan viskositas. Lama penyimpanan berpengaruh semakin tinggi tingkat peroksida dan tingkat viskositas, tetapi kadar asam lemak bebas semakin menurun. Kombinasi perlakuan konsentrasi ekstrak andaliman dan lama penyimpanan tidak menunjukkan perbedaan yang signifikan pada parameter yang diamati. Ketahanan oksidatif ekstrak andaliman pada K1 sebesar 40,38%, K2 sebesar 45,20%, K3 sebesar 49,05% dan KBHT sebagai pembanding sebesar 54,55% yang menunjukkan besarnya aktivitas antioksidan.
