Abstract

Health is one of the main factors contributing to the quality of life. Good health is resulted from various factors. including the quality and quantity of food intake. Many researches show that nutritional factors contribute in the prevention of degenerative diseases, such as heart disease and cancer. Carrot is one kind of root vegetables that widely consumed, contains health promoting compounds. particularly carotenoids. Boiling is one of ca"ot processing methods usually done at household level. The boiling of ca"ot was supposed to influence carotene content of carrot and therefore would change its antioxidant activity. The aim of this study was to study the changes of carotene content and antioxidant activity of carrot during boiling process. The carotene content and antioxidant activity were analyzed by open-column chromatography (OCC) followed by spectrophotometer and by 2,2-diphenylI- picrylhydrazy/ (DPPH) methods, respectively. This study found that carrot boiledfor 24-30 minutes had the highest antioxidant activity. and more than 30 minutes of boiling. the antioxidant activity was decreased. In order to get the highest carotene content and antioxidant activity of boiled ca"ot {with usual shape made in household processing. which is cross-sectional slices with 2-4 mm thickness}. the boiling time therefore should be 24-30 minutes.

Abstract

Badung Regency is the fourth city which is the largest waste producer in Bali Province, with the amount of waste production in Badung Regency in 2022 reaching 119,475 tons per year. On the other hand, the generated waste is only disposed of at the Suwung Final Disposal Site (TPA), without prior processing. However, as of March 2023, the Bali Provincial Government has begun to gradually close the Suwung TPA, due to waste overcapacity, as evidenced by the presence of rubbish piles as high as 25 meters. In response to this, the Badung Regency Environmental Service (DLH) built the Mengwitani Integrated Waste Processing Site (TPST), where waste is processed into Refuse Derived Fuel (RDF) with the aim of reducing waste generation in Badung Regency. This research aims to evaluate the process of processing waste into RDF at the Mengwitani TPST, so that it can be seen how much waste generation can be reduced through RDF processing at the Mengwitani TPST. The method used is a quantitative method, with a mass balance analysis approach. Therefore, it was found that processing waste into RDF was carried out by going through 5 stages of filtering or segregation. So, after processing the waste into RDF, it was found that the potential for waste reduction at the Mengwitani TPST reached 72% every day, and on the other hand, the RDF produced by the Mengwitani TPST had been adjusted to standards, namely SNI 8966:2021.
