This study aimed to determine the urine as a substitute of sulfuric acid as a source of energy. It was found timely and relevant to address the high cost of electricity, a common problem in the society. The researchers experimented urine to make as an alternative light energy source that can be applied in the University of Rizal System Rodriguez campus. The researchers conducted experimentation which focused on collecting and processing of urine to use as a substitute of sulfuric acid as a source of energy conducted at URSR chemlab (T105). Using the different variables such as volume of urine, voltage generated and the light duration, the research study became comprehensive. This experimental research was inspired by the different related studies about urine's potential characteristics to conduct and produce electricity. These were urine battery turned pee into power issued on National geographical news, Herriot Watt University in Edinburgh's carbamide power system, water less urinals to power parts of the city in New Delhi and in the Philippines, similar study was conducted by Mr. Roderick Siena of BJMP (Bureau of jail Management and Penology).

On the applied system of prototype using urine as substitute of sulfuric acid, it showed that one thousand ml volume of urine had a mean of two hundred twenty six hours which was very effective than four hundred ml volume of urine which measured only a mean within eighty two hours while in terms of voltage generateda four hundred ml of urine had 3.3V mean which was very effective than in a one thousand ml of urine had 3.7V mean which was slightly effective. This was because the light magnitude was very bright compared to higher voltage of light bulb. The effectiveness of urine as a substitute of Sulfuric acid (H₂SO₄) as source of energy based on the significant difference between three trials in terms of light duration, it is reflected on the table the f value is 1.47 while the p value is 0.997 which is greater than 05 level of significant. Therefore, the null hypothesis was failed to be rejected, there is no significant difference between the different trials in terms of light duration. The effectiveness of urine as a substitute of sulfuric acid (H₂SO₄) as source of energy based on the computed analysis of variance (ANOVA) as it is reflected on the table, it is reflected on the table the f value is 0.901 while the p value is 0.875 which is greater than 05 level of significant. Therefore, the null hypothesis was failed to be rejected, there is no significant difference between the different trials in terms of voltage generated. This research procedure included the preparation, gathering of information, collection of urine samples, system preparation and application of constructed system.

Based on the findings, the researchers concluded that urine was an effective substitute of sulfuric acid. Its effectiveness depends on its volume and voltage of the light bulb The higher the volume of urine is the longer the light duration The lower the voltage, the brighter the light intensity but it may vary depending on the amount of urine provided in the prototype. The researchers also found out that in a small amount of urine poured inside the lead acid battery could make the old battery charge again.

From the findings, the following were recommended. For the community that suffered most especially in some remote areas and some residences which suffered from frequently increase in electric bill, the use of urine as a substitute of sulfuric acid to generate energy by installing a mechanical charger to speed up the urine in acid lead to generate light without musing the electricity came from some substation and distributors of energy like MERALCO and NAPOCOR may be considered as an alternative. The government can also support this study by providing materials such as alternator, wires, acid lead batteries that could create light energy source using urine which can help people and society save money Moreover, these research findings can be helpful to the future generation especially when they are all eager to find ways or how the effectiveness can be speed up to power not only a light bulb but also to different appliances
