Abstract

Misuse of formalin and borax is still common, including processing and preserving fish. Therefore, this study aims to identify the presence of formalin and borax in tuna on the market Ngemplak, Tulungagung regency. The samples used in this study were fresh tuna in the Ngemplak market originating from the beaches of Prigi, Sine, Tambakrejo, Popoh and Sidem. The samples were tested qualitatively using the colorimetric method by Schryver reagent for formalin and curcumin paper for borax. The results obtained in this study, from the five tuna samples not detected contained formalin and borax which were marked by no change in color in the test. Tuna sold in the Ngemplak market Tulungagung regency negatively contains formalin and borax, making it safe for consumption. It is hoped that the relevant office will carry out routine checks on the misuse of food additives, especially preservatives circulating in the community and the public should always be careful in choosing safe food.

Abstract

Farmers in Pucung Kidul Village often use pesticides to eradicate pests, diseases, and weeds on plants. Pesticides contain several kinds of metals, including cadmium (Cd) and copper (Cu). High levels of cadmium in the blood can interfere with the process of erythropoiesis and heme synthesis caused by the accumulation of cadmium. While copper poisoning can cause degenerative processes in the brain and cirrhosis of the liver. This research is a descriptive study that aims to measure the levels of cadmium and copper in the blood of farmers in Pucung Kidul Village. Measurements were made using atomic absorption spectroscopy (AAS). The sample used in this study was 15 samples obtained by the purposive sampling technique. The results showed that all respondents did not use PPE and 2 respondents with a working period of > 5 years obtained cadmium levels from 15 samples, there was 1 sample with cadmium levels above the threshold, which was 0.047 mg/L. Meanwhile, the copper content of the 15 samples contained 1 sample with the copper content above the threshold, which was 1.27 mg/L. This shows that the proper use of PPE, also years of service, and age can affect blood levels of cadmium and copper. Where the longer the working period, the more exposure that occurs and causes high levels of cadmium and copper in the blood. With the results of this study, it is hoped that farmers will continue to use personal protective equipment (PPE) when using pesticides and wash their hands after using them.
