Lemongrass (Cymbopogon citratus (DC.) Stapf, Poaceae) has been known for demonstrating anti-microbial activity against food spoilage bacteria. These antimicrobial properties can be further utilized for the development of natural food preservatives. In this study, the compounds present in water extract and essential oil of lemongrass were analyzed and their potential as tofu preservatives was evaluated. The water extract was prepared by the infusion method, while the essential oil was made by steam and water distillation. The phyto-chemicals composition of the water extract and essential oil was analyzed by qualitative colorimetric phyto-chemical screening and Gas Chromatography-Mass Spectroscopy (GC-MS) technique, respectively. Their preservative activity on tofu was evaluated by observing their ability to inhibit the growth of bacteria on the tofu and the physical changes of tofu during 10 days of preservation at room temperature. The results showed that lemongrass water extract contained terpenoids, tannins, and saponins. The GC-MS analysis identified 13 compounds in the essential oil. Neral, geranial, β-myrcene, juniper camphor, and viridiflorol were found as the major compounds. At concentration of 20%, lemongrass water extract demonstrated inhibition of bacterial growth during 10 day storage of tofu and improved the shelf life by 4 days longer from those of the negative control. In contrast, lemongrass essential oil did not show inhibitory activity in bacterial growth in tofu but it was capable of maintaining the color, odor, and texture of tofu as well as delaying the slime formation up to 4 days.

Galangal (Alpinia galanga (L.) Willd.) has been long used for medicinal purposes. It showed promising effects on the food-spoilage microorganisms and is commonly used as spices in various cuisines. This study aimed to evaluate the microbial growth inhibitory activity and the preservation potential of galangal water extracts on tofu. The water extracts were prepared by infundation method in the concentrations of 5, 10, and 20%w/v. The phytochemical compounds in the extracts were screened as per standard methods. The tofu was preserved by immersion method for eight days under room temperature with an evaluation time point of two days. The microbial growth inhibitory activity was evaluated by indirect optical density (OD)-based enumeration, and the OD reduction by the extracts was calculated accordingly. The preservation potential was calculated from the changes of the physical characters on tofu evaluated by sensorial analysis. Galangal water extracts contained tannins and terpenoids. It concentration- dependently inhibited microbial growth on tofu, and the extract showed the best OD reduction at a concentration of 20%. It changed the color of tofu but maintained its texture. It also masked the odor of fresh tofu with the aromatic galangal scent. All three tested concentrations showed an equal preservation potential of 2 days. Our data suggested galangal water extract in the optimum concentration of 20% inhibited the microbial growth on tofu and potentially preserved it for two days. This moderate preservation effect might be attributable to its tannins and terpenoids content.

Cattle manure contains high organic matter, so that this material is commonly used as plant nutrients in a form of organic fertilizer. In order to get a better understanding on the use of cow manure, the objectives of this research are (1) to determine the influence of liquid waste and solid livestock as fertilizer on soil quality and (2) to study the effect of both liquid and solid fertilizer on coffee plant growth. In this research, Completely Randomized Design (CRD) was employed as a research design, while data analysis was conducted using ANOVA. The F statistical test was applied to measure whether all independent variables could influence the dependent variable by using 5% and 1% (Alpha) degrees. The results showed that one time application of livestock wastewater improved C-organic chemical properties, N, P, CEC, Ca and Mg while soil chemical properties of pH, K, Na decreased. Two times application of livestock liquid fertilizer treatment improved soil chemical properties pH, N total, Ca, Mg and saturation bases. As for solid waste, one time treatment increased chemical properties of pH, C organic, N total, Ca and saturation of the base. The two times treatment could improve soil chemical properties of pH, N. total, P, Ca, Mg, base number and base saturation. Liquid waste fertilizer also found to provide significant effect on plant height and coffee plants quality. Additionally, (3) solid waste (compost) was found to have a significant effect on plant height, plant height rate and number of buds.
