Daftar Isi:
- The determination of profenofos pesticidal residue in the lettuce (Lactuca sativa L.) by using gas chromatography using flame photometric detector (FPD) had been investigated. The lettuce was collected from Padang Luar area, Agam distric, West Sumatera. Sample for determination of profenofos residue divided into three groups: unwashed (A), washed with water (B), and washed with detergent (C). Maceration with sonication was used for the extraction using ethylacetateas a solvent. The results showed that profenofos pesticide residue in sample A, B and C were 0.204, 0.080 and 0.061 ppm, respectively. These profenofos pesticidal residue are over than the Maximum Residue Limits (MRL) that established by The Japan Food Chemical Research Foundation (0.05 ppm) even though World Health Organization (WHO) has not established Maximum Residue Limits (MRL) profenofos on lettuce. Based on the statistical analysis one-way method (Anova) using SPSS 20.0 showed that there was a significant concentrations difference between lettuce A from lettuce B and lettuce C with p < 0.05.
- Telah dilakukan pemeriksaan residu pestisida profenofos pada selada (Lactuca sativa L.) menggunakan metode kromatografi gas detektor fotometri nyala. Sampel sayuran selada di ambil dari daerah Padang Luar, Kabupaten Agam, Sumatera Barat. Sampel untuk penentuan kadar residu profenofos dibagi atas tiga kelompok yaitu tidak dicuci (A), dicuci dengan air (B), dan dicuci dengan deterjen pencuci sayuran (C). Maserasi dengan sonikasi digunakan untuk ekstraksi menggunakan pelarut etil asetat. Hasil penelitian menunjukkan bahwa residu pestisida profenofos pada selada A, B dan C berturut-turut adalah 0,204; 0,080 dan 0,061 ppm. Residu pestisida profenofos ini melewati Batas Maksimum Residu (BMR) yang ditetapkan oleh The Japan Food Chemical Research Foundation (0,05 ppm) sedangkan World Health Organization (WHO) belum menetapkan Batas Maksimum Residu (BMR) profenofos pada selada. Hasil analisis statistik Anova satu arah menggunakan SPSS 20.0 menunjukkan bahwa terdapat perbedaan konsentrasi yang signifikan antara selada A dengan selada B dan selada C dengan nilai p < 0,05.
