Abstract

Noni is a plant that has the potential to be used as traditional medicinal ingredients. This study aims to determine the inhibition of noni extracts (Morinda citrifolia L.) in inhibiting the growth of the fungus Candida albicans. This type of research is experimental. A total of 150 grams of dried noni fruit that has been mashed, macerated with three different types of solvents namely aquades, acetone and n-hexane to obtain thick extract. Preparation of the fungus suspension was Candida albicans made by mixing the media Nutrient Broth with 5 ose test fungus that were equated with turbidity of a standard MC. Farland. The fungus suspension made was implanted on the Sabouroud Dextrose agar to solidify and divided into 7 sterile petri dishes. Testing the inhibition of fungi using the method of wells. Each cup is made of 1 hole diameter of 3 cm in the center. Tests were carried out by adding non-solvent aquades fruit extract into the 1 cup, acetone noni fruit extract into the cup 2, n-hexane solvent noni fruit extract into the cup 3, for 3 other plates added with three solvents as negative control, while for 1 cup added to the cup fungal infection drug is nystatin as a positive control, each as much as 1 mL. Measurement data were analyzed using the formula of the percentage of inhibition. Inhibitory power of noni fruit extract using distilled water is 3.55%, noni fruit extract using acetone solvent is 50.15%, noni fruit extract using n-hexane solvent that is equal to 38.83%. negative control of aquades, acetone and n-hexane solvent has no inhibitory power while positive control of nystatin is 9.73%. Noni fruit extract using acetone solvent has the strongest inhibitory ability. It can be concluded that the noni fruit extract has fungal inhibitory effect on the growth of the fungus Candida albicans

Abstract

Generally, buildings consume around one-third of the world's total energy. Most of the energy in buildings in Indonesia is used by air conditioning systems. One effort to minimize energy waste in the building's air conditioning system is by lowering OTTV (Overall Thermal Transfer Value) to reduce external heat entering the building sheath. The study aims to analyze geometry and WWR (Window to Wall Ratio)’s influence on OTTV and building energy consumption through manual calculation and simulation processes on Autodesk Ecotect Analysis software. This research uses experimental quantitative methods by taking the Bosowa Tower located in Makassar as the research object to serve as a control variable in making alternative building models. The results showed that geometric and WWR variations in buildings were sufficient to affect OTTV values and cooling energy consumption. The smaller the ratio between the length and width of the base and the smaller the percentage of WWR in the building, the smaller the OTTV value and cooling energy consumption of the building. From this study, the most effective combination of geometry and WWR applied to buildings is the combination of 1:1 and WWR 15%.
