Quantification of Bioethanol Derived from Selected Renewable Coconut Raw Materials Using Simple Fermentation-Distillation Process

2024-12-04T00:36:17+00:00

Coconut (Cocos nucifera L.) is a major crop in the Philippines which entails a large volume of young coconut water (YCW), mature coconut water (MCW), young coconut husk juice (YCHJ), and coconut sap (CS) can be produced all year. The growing demand of bioethanol as a fuel blend to gasoline paves the way to the search for feedstock that can contribute to the bioethanol need of the country. YCW is normally processed as a refreshment product but due to the large volume of consumption, young coconut water is normally discarded. Moreover, MCW is considered as waste in the market after the extraction of coconut meat. The young coconut husk is considered waste and can be processed as a potential source of bioethanol. The coconut sap was explored considering the number of coconut trees in the country. The initial sugar concentration of the YCW, MCW, CS, and YCHJ are 4.39 + 0.3, 3.76 + 0.44 , 9.51 + 1.86, and 4.85 + 0.65 ⁰Bx, respectively. The fermentation process was done for 72 hours using Saccharomyces cerevisiae as the fermenting yeast. The obtained bioethanol yields for YCW, MCW, YCHJ, and CS were 31.67, 15.71, 16.89, and 64.42 mL of ethanol per liter of their raw materials, respectively. The highest bioethanol yield was obtained using the CS and a lower energy is required in the process because of its high initial sugar concentration. The production cost was computed for each raw material that was shown to be higher compared to the bioethanol price index of Php 81.68 per liter using sugarcane molasses as feedstock.

Improving Work Quality in Painting Between Wall and Ceiling Areas Using a Paint Edger

2025-05-02T06:24:31+00:00

In the painting process, many tools have been proposed to paint the wall and keep the ceiling from being exposed to the paint color. The workers’ main problem is that they have to use a ladder to reach the ceiling and place tape between the wall and ceiling. This technique was employed to shield the paint-exposed area, particularly when the ceiling and wall were painted in contrasting colors. Because the tape absorbs the color of the painting, its quality typically does not match the ceiling’s surface, and when the worker tries to remove it, the color is still visible on the ceiling. The objective of the study is to implement a new additional tool to attach to the paintbrush in order to paint between the ceiling and wall area smoothly and neatly. To complete this study, the primary data collection was conducted through interviews with the painters at a construction site in Padang Besar, Perlis. The techniques of brainstorming, benchmarking, and morphological charting are used to produce and develop good ideas, which are expressed in detailed sketches and technical drawings. The polylactic acid (PLA) material was used in the 3D printing process to create the tangible prototype. The new additional tool that is called a paint edger, is attached to the paintbrush and this product can save working time to paint the area of the ceiling and wall by 32.9% compared to the conventional method. Moreover, the risk of the fall can be reduced by using the paint edger, whereas it uses the extended pole to complete the work with the same quality.
