Abstract

Degradation of Metanil yellow has been done. In this research the degradation process was done by photolysis and sunlighting method by using TiO2-SnO2 catalysis. The residu of metanil yellow was centrifuged and measured by UV/Vis Spectrophotometer at 300 – 600 nm after degradation. 6 mg/L of Metanil yellow and addition of 0,03 g TiO2-anatase and SnO2 for 150 min, gave the percentage of degradation 27,38 % and 25,00 % after photolysis. 6 mg/L of Metanil yellow and addition of 0,03 g TiO2-anatase and SnO2 for 150 min, gave the percentage of degradation 94,84% and 93,25% after lighted by sun with 1,13256 1015 foton cm-2/s intensity. From the results percentage of degradation showed that degradation with the addition of TiO2-anatase and SnO2 can improve the degradation of methanil yellow. The percentage of degradation proves that the addition of TiO2-anatase and SnO2 which is lighted by sun is better than photolysis process.

Abstract

Peredaran minuman ringan tak berlabel yang dijual oleh pedagang kaki lima dalam proses produksi masih diragukan keamanannya sehingga menimbulkan keresahan pada masyarakat. Oleh karena itu, perlu pengetahuan tentang food safety knowladge and practice. Untuk meningkatkan kualitas dan keamanan produk dibutuhkan penerapan HACCP. HACCP menggunakan Panduan Penyusunan Rencana HACCP yang direkomendasikan oleh Standar Nasional Indonesia. Hasil HACCP menunjukan bahwa yang ditetapkan sebagai CCP adalah proses perebusan air mineral, penambahan pewarna/sirup/bubuk pop ice dan pengemasan. Penerapan HACCP yang sesuai akan meningkatkan kualitas dan keamanan produk minuman ringan tak berlabel yang dijual pedagang kaki lima.

Abstract

Degradation of malachite green has been done. In this research, degradation process of malachite green was done by ozonolisis method, using TiO2- anatase and ZnO catalyst. The residu of malachite green was centrifuged and measured by spectroscopy UV / Vis at 200-800 nm after degradation. 6 mg / L malachite green diozonolisis for 5 minutes obtained pH optimum at pH 7. 6 mg / L malachite green was added 0.025 mg TiO2-anatase catalyst, and 0.025 mg ZnO at pH 7 with a variation time obtained optimum time of 5 minutes. Percent degradation of malachite green is generated by the addition of 0.0250 grams of TiO2-anatase 99.77% and 0.0250 grams of ZnO 93.59%. Percent of the results showed that the degradation of degradation with the addition of TiO2-anatase is greater than the addition of ZnO, because of the stability of TiO2- anatase is large.
