    Analysis of the factors to sugarcane production and farmers' planting intentions in the provinces of Davao del Sur, Sarangani and South Cotabato
    Granada, Ijade T. (Davao del Sur State College, 2025-06)
    The study aimed to analyze the factors to sugarcane production and planting intentions of sugarcane farmers in Davao del Sur, Sarangani and South Cotabato. The study utilized a descriptive-quantitative survey research design, administered to the 89 selected medium-large scale sugarcane farmers using sampling technique. The study used statistical tools to analyze and describe the study. The results showed that the sector was largely composed of aging farmers with limited formal education, which may hinder the adoption of modern farming techniques. Farm-related issues such as hilly/rolling terrains and dependence on rainwater heightened vulnerability to climate variability. Economic and social factors highlight farmers' strong influence sugarcane production. Consistently, correlational analysis showed that economic factors had the strongest and appeared most significant to farmers' planting intentions. Multiple regression confirmed economic factors as the sole predictor on farmers' planting intentions. Based on the findings, the Department of Agriculture and State Universities and Colleges should launch youth-targeted agricultural programs in modern sugarcane farming techniques. The government agencies should introduce mechanization suited for hilly/rolling terrains including irrigation projects to reduce reliance on rainwater and provide production support programs and policy efforts in strengthening market prices, minimizing costs and access to affordable credit for the sustainability of sugarcane farming.

    Yield and quality analysis of bioethanol produced from waste coconut water (Cocos nucifera L.) and sugarcane molasses under different fermentation conditions
    Rom, Ferly Jane N. (Davao del Sur State College, 2024-05)
    Bioethanol production involves materials containing sugar to be converted into alcohol. It is a process that requires fermentation, where active organisms are utilized to break down sugar and turns them into alcohol. The purpose of this study was to determine the ideal conditions in the fermentation of waste coconut water and sugarcane molasses with initial pH level between 4.0 - 5.0 for six days in order to produce good quality of bioethanol. the experimental samples were laid in complete randomized design (CRD) with three treatments, namely; T 1 (Aerobic), T2 (Anaerobic) and T3 (Aerobic-anaerobic) and each was replicated four times. The parameters assessed were pH level after fermentation, alcohol content (%), ethanol content (%) of the bioethanol. The gathered data was analyzed using One-way ANOVA and LSD at 5% level of significance. Based on the results, T3 obtained the highest mean pH level of 3.15 after fermentation and alcohol content of 1.6%, followed by T2 with a mean pH level of 3.0 and an alcohol content of 1.1%. T1 obtained the lowest mean pH level of 2.92 after fermentation and an alcohol content of 0.4%. The results revealed further that T3 produced highest percentage of ethanol content of 24.4% and yielding 2.8% bioethanol, followed by T2 obtaining 16.4% ethanol content and yielding 1.8% bioethanol. Lastly, T1 got the lowest ethanol content of 3.01% and yielding 1% bioethanol among the tree treatments. The ANOVA results revealed that there's a high significant difference in terms on the pH level after fermentation and alcohol content (%) among the means of the three treatments. Generally, based on the results, the researcher concludes that, T3 (Aerobic-anaerobic) is the most effective condition in the fermentation process of waste coconut water (Cocos nucifera L.) and sugarcane molasses utilizing Saccharomyces cerevisiae for bioethanol production.
