Abstract

Siamese oranges are a member of the tangerines which have the scientific name Citrus nobilis var.Microcarpa. It is called Siamese orange because it comes from Siam (Muangthai). The quality of Siamese oranges is determined by their physical properties. These physical properties include size, weight, volume and diameter. Post-harvest technology for Siamese oranges can be done by grading to obtain quality Siamese oranges according to standards. This research aims to determine the physical properties of Siamese oranges used in the grading process. Determination of sphericity and roundness is measured using a caliper. Determination of volume and density is measured using a beaker. Analysis of research data used a one-way z-test normal distribution to the left. The results of data analysis show that the z-count value of roundness, roundness, volume and density is 1.05; 0.79; 0.55; 0.53 and -ztable of -1.645. This means zcount ≥ -ztable, where the average value of the physical properties of Siamese oranges is greater than or equal to the research object, roundness is 0.92, roundness is 0.93, volume is 87 cm3 and density is 1.02 g/ cm3. Thus, the results of these physical properties can be used as a reference when grading Siamese oranges code size 2.

Abstract

Cilok is a food product from West Java made from cassava flour, meat and spices. This product is very popular among the people of Bondowoso Subdistrict, Bondowoso Regency. Unfortunately, there are some cilok sellers who have indicated that they add borax in the processing process to extend the shelf life of the cilok. In fact, borax should not be consumed as it can be harmful to human health. This study aims to determine the presence of borax in cilok sold by vendors at various locations in the Bondowoso sub-district. This type of research is descriptive. The sampling technique used was cluster sampling. The samples used in the study were cilok sold by 4 cilok sellers at different locations in Bondowoso District, Bondowoso Regency. The data analysis technique used in this study was qualitative descriptive analysis. The results showed that all four cilok samples tested were negative for borax and therefore safe for consumption. This shows that cilok sellers are aware of good and safe food processing.
