Abstract
The field practice was conducted at Central Luzon State University-Center for Renewable Energy and Technology (CLSU-CREaTe) located at CLSU compound, Science City of Muñoz, Nueva Ecija from October to December 2023. The field practice Activity 1 aimed to evaluate a 250L semi-automated bioreactor using AC and solar powered source. The objectives of this activity were to 1) evaluate the semi-automated bioreactor using AC and solar-powered source; 2) determine the fermentation efficiency of the semi-automated bioreactor using AC and solar-powered source; and 3) comparison of power consumption of AC and solar powered source.
The field practice activity 2 aimed to design an 800L tank capacity of bioethanol distiller. the specific objectives of this activity were to 1) determine the optimum area and height of an 800L tank capacity bioethanol distiller; 2) determine the other components of the bioethanol distiller.; 3) layout a design of a bioethanol distiller and 4) prepare a bill of materials of the bioethanol distiller.
The field practice activity 3 aimed to perform other activities. The specific objectives of this activity were to: 1) perform other activities that will be assigned by the director of center, the supervisor of student-trainee or any CLSU-CREaTe personnels; and 2) promote the student's readiness and flexibility in their respective specialization.
The 250L semi-automated bioreactor was evaluated for fermentation efficiency using AC and solar power sources. The results showed a fermentation efficiency of 81.7% for the AC which consumed 6.25 pesos, and 83.5% for solar power source. The fermentation efficiency is almost identical however, using solar-powered source saves money than using AC. But, the cost to build the solar-powered source is much greater.
The bioethanol distillers' design, which holds a capacity of 800L, has been up scaled to a larger size. The design includes a tank, reflux column, primary condenser, slanted secondary condenser, vertical secondary condenser and frame. the final dimensions were calculated to ensure the machine's efficiency and durability.
Moreover, the student gained experience with several aspects of renewable energy. the study participated in events, conducting and evaluating machines, and engaging in equipment assembly, which are all agricultural and biosystems-related tasks during the time frame of the field practice.
