Abstract

In Yogyakarta City, the most waste comes from markets and settlements. One market that produceshighest waste is Kranggan Market which produces 95% of organic waste, containing vegetablesand citrus fruit waste. The purpose of this study was to determine the effect of ingredientscomposition of citrus waste on the chemical content (N, P, K and pH) of organic liquid fertilizer.The study was a quasi experiment with post test only design. The study data was analysedusing one way anova at 0.05 significant level, and the results show that the N content obtainedp-value 0.961, the P content was 0.962, the K content was 0.948, and the pH was 0.702. The Ncontent had the highest average at 2 kg, i.e. 0.08%; meanwhile the K content was at 3 kg composition,0.05%; and pH was at 3 kg composition, 3.7. It can be concluded that the all compositionshave not meet the required minimum standards, meanwhile the P content has fulfilledSNI 19-7030-2004 with standard >0.10%, i.e. at 1 kg composition has an average of 0.10%, at 2kg composition, of 0.11%, and at 3 kg composition, of 0,11%. It can be concluded that the overallliquid organic fertilizer from citrus fruit waste have not meet the 2004 Standards. Therefore, itadvised for subsequent studies to add raw materials consists of vegetables or fruit which containhigh levels of nitrogen, phosphorus and potassium.

Abstract

Food security is an effort needed to prevent food from possible biological, chemical or physicalcontamination that can endanger human health. Wingko is a semi-wet food that can be easilyovergrown with mold. Wingko production activities are closely related to the use of packagingpaper and the type of coating paper. One natural ingredients containing essential oils, flavonoids,and tannins as antimicrobials are galangal. The aim of the study was to know the concentrationvariation of galangal coated paper to inhibit of mold contamination on wingko. The studywas an experiment with post test only control group design. The data collection techniqueswas visual observation and using a checklist. The observation was carried out on wingko afterhave been exposed to galangal coated paper during the end of the shelf life or the appearanceof mold. The observation of the mold was on top, bottom, right and left sides of the wingko surface.The results showed that among the 3 variations of treatment (30%, 40%, 50%) and thecontrol, the mean of the shelf life of Wingko after intervention, were 5; 5; 5,3; and 4.1 days, respectively.Based on data analysis, it can be concluded that the addition of galangal liquid with50% concentration to coateing paper is the best variation of for inhibiting mold contamination onwingko and is able to extend the shelf life of wingko.
