Anaerobic Digestion of Cow Dung as an Alternative Biogas for Cooking in Barangay Dumantay, Batangas City

Abstract

INTRODUCTION

The challenges in energy supply have been prevailing in the global community. This situation has become a problem for many countries across the world, and the Philippines is no exemption. Energy is very essential in meeting the basic needs of the people, but the rising price of the commercial fuel, mostly used by the Filipinos, remains unresolved. Given such an alarming dilemma, the researchers became aware of the difficulty for a simple family to afford the commercial fuel available in the market, especially now that prices of commodities tend to balloon each year. in this study, the researchers intended to create an elective wellspring of fuel that will solidly enhance the life of the occupants and help mitigate this growing problem.

METHODS

Using a quasi-experimental strategy for investigation, the researchers exploited the focus group by purposive sampling. They utilized polls where 20 residents living in Barangay Dumantay, Batangas City served as participants. A portion of the methodology that they used in the investigation were planning, experimentation and the making of the alternative fuel.

RESULTS

The anaerobic digestion of cow manure as the main ingredient for biogas production offers different properties: the cow manure's odor does not affect the biogas production and it can be repeated as long as there is cow manure. Furthermore, the residents agreed that cow manure is an effective source of fuel for cooking, and it does not leave a bad effect on the household. in addition, they strongly agree that the alternative source of fuel is more affordable than the commercial one. The null hypothesis is rejected that the anaerobic digestion of cow manure is not as effective as an alternative source of fuel for cooking. The main ingredient of the alternative source of fuel can be easily found in the surroundings, making it very feasible for a common family.

DISCUSSIONS

The results showed that the biogas production from the anaerobic digestion of cow manure is an effective alternative source of fuel for cooking. It can be beneficial not only for the residents but for the environment as well. It may be considered as a useful component in different aspects of the community’s. Moreover, the Department of Agriculture may consider cow manure as a means of improving the lives of the residents as well as the cow owners. However, future researchers may work with a better product with ample and better materials and equipment.
