Abstract

Pemindangan is one of the traditional fish preservation efforts by boiling and salting methods that are mostly carried out by the people of Indonesia, especially in Bali. Pemindangan process does not only produce products in the form of pindang, but also produces residual products or waste that pollutes the environment. Eco-enzyme is a solution of complex organic substances produced from the fermentation process of organic waste, sugar, and water. Until now, research on eco-enzyme with the basic ingredients of orange peels is still very little. Differences in raw materials will of course produce different products. In addition, research to see the application or effect of eco-enzyme on waste, especially pemindangan waste has never been carried out. The research used an experimental method includes the manufacture of eco-enzyme and treatment of pemindangan waste with an eco-enzyme. A total of 6kg of samples of Siamese Kintamani Orange (Citrus nobilis) peels waste used for the manufacture of eco-enzymes were selected by purposive sampling. The eco enzyme was made by mixing Siamese Kintamani orange peels, water, and sugar in a ratio of 3:10:1, afterwards, the mixture was put in a closed container. Fermentation was carried out for 3 months. The treatment was given to the pemindangan liquid waste taken from Kusamba village as the centre of pemindangan in Bali and separated into 3 containers based on the treatment, namely treatment A without eco-enzyme, treatment B with addition of eco-enzyme 10%, and treatment C with addition of eco enzyme 50%. Eco-enzyme based on Siamese Kintamani orange peels waste can reduce the levels of TSS, TDS, PH, and ammonia levels in pemindangan waste, both at 10% and 50% dilution. However, the eco-enzyme is not able to reduce the BOD and COD parameters in the pemindangan waste. Eco-enzyme requires a longer therapeutic time to be an alternative chemical treatment for pemindangan waste.
