Sensory Acceptability and Nutritional Content of Cereal Bars formulated with Adlay (Coix lacryma-jobi L.) grains النص الكامل
2024
Nia Allison C. Juliano | Paul Alteo A. Bagabaldo
In the Philippines, an underutilized crop known as adlay has been found to contain valuable nutritive potential. Given Filipinos’ usual diet of snacks and ready-to-eat food items, the study aimed to provide an alternative choice for healthy snacks by utilizing adlay in developing cereal bars with an improved nutritional profile. The study developed cereal bars using varying proportions of oats and adlay grains as follows: control (100:0), treatment 1 (75:25), treatment 2 (50:50), and treatment 3 (25:75). The cereal bars were then subjected to sensory evaluation to determine their acceptability using a nine-point hedonic scale with 67 adult respondents. The control and the most acceptable treatment then underwent proximate and mineral analyses (iron and calcium). The sensory data was analyzed using Kruskal-Wallis H-Test with rank analysis, whereas the proximate and mineral content data were analyzed using the student’s t-test at p<0.05. Results showed no significant difference between the control and all the treatments regarding sensory characteristics, and treatment 1 got the highest rank among all treatments. Proximate and mineral analyses revealed that treatment 1 has significantly higher crude protein (11.25 ± 0.66%), crude fiber (10.79 ± 1.22%), crude fat (17.82 ± 1.10%), and calcium (1.08 ± 0%), than the control made of pure oats. The findings, therefore, suggest that adlay can be used as a value-added ingredient in making sensory-acceptable cereal bars with an improved nutritional profile.

Charmaine Samala Guno
Solar irrigation systems are sustainable practices that can improve the well-being of local communities and enhance the resilience of agriculture to climate change while reducing environmental impacts. Due to its high investment cost, small-scale farmers are inclined to use traditional fossil-based irrigation systems that can harm humans and the environment. This study aims to analyze the environmental impacts, economic feasibility, and social acceptability of shifting agricultural practices from diesel-fueled to solar irrigation systems. Taking the perspective of small-scale farmers from Calapan City, Oriental Mindoro, results found that solar irrigation system has a higher initial investment but lower maintenance and operational costs. These resulted in an attractive economic feasibility of the project with Php 19,693 of fuel cost savings per hectare per year, a project net present value of Php 10,214 per hectare, a payback period of 8.27 years, and returns on investment at 110%. Additionally, shifting to a solar irrigation system significantly reduces the greenhouse gas emissions from diesel at 199.78 CO2 eq/ha/yr, and avoids air pollutant emissions at 14.91 g/ha/yr particulate matter, 2.98 g/ha/yr nitrogen oxides,193.82 g/ha/yr sulfur oxides, and 149.09 g/ha/yr carbon monoxide. Despite the lack of in-depth environmental awareness, small-scale farmers are interested in investing in solar irrigation systems with 68% social acceptability. Results provide bases for recommendations on promoting more human ecologically and sustainable agriculture irrigation systems in the Philippines and other developing countries.

Maria Criszel Joy L. Alpe | Recylyn I. Bayna-Mariano
With the rise of video gaming trends within the Philippines, the risk of malnutrition related to escalated sedentary behavior and poor dietary habits may also occur. This research aims to describe the association between the video gaming lifestyle, dietary habits, and physical activity level (PAL) of university students aged 18-24. The study follows a descriptive study design and uses Spearman’s rank correlation coefficient to determine the relationships of the variables. After correlation tests, gaming addiction level was found to have a weak direct relationship with the frequency of consumption among all food groups (ρ = 0.138±0.047). Weak positive correlation was also discovered with excessive gaming and meal skipping (ρ = 0.184), self-reported loss of appetite (ρ = 0.070), and tendency to eat their meals in front of their gaming devices (ρ = 0.160). Furthermore, PAL is found to have a weak positive correlation with gaming addiction level (ρ = 0.074). Among the sample, excessive video game use was found to be related to all variables, whereas higher chances of becoming pathologic gamers may also imply a tendency in the participant’s increased consumption of caloric-dense foods, poor dietary habits, and moderate to high PAL.

This study aimed to assess the acceptability of arrowroot flour (Maranta arundinacea L.) in the production of salt bread (pandesal) in the country. Two experiments were conducted namely, pre-experiment and actual experiment. The pre-experiment had two trials in making pandesal wherein the first trial focused on producing traditional pandesal (T1, 0%) while the second trial used different percentages of arrowroot flour (T2, 20%; T3, 30% and T4,40%) to determine the optimum ratio with selected flours. The acceptability used a 9-point Hedonic scale wherein 9 is the highest (Like extremely) and 1 (Dislike extremely). Results showed that T1 had the highest general acceptability (7.8, ) followed by T3 (7.5) and both were labeled as ‘Like very much’ while T2 (6.8) and T4 (6.7) were both labeled as ‘Like moderately’. In terms of cost, T1 was the cheapest and T4 as the most expensive. While arrowroot-based flour pandesal is more expensive right now, it was found out to acceptable flour substitute in making pandesal. The use of this flour as alternative in producing bread can help address the problem of the country’s heavy dependence on imported flour. Result of this study and further studies on the use of arrowroot flour will support local farmers in growing arrowroot for other potential uses.

Increasing population and rapid economic growth result in waste management problems in the Municipality of Bay, Laguna. In response, the municipality is planning to invest in an Integrated Waste Management Technology System (IWMTS) that aims to generate public revenue. Key informant interviews, surveys, and focus group discussions were utilized for data collection. Results showed that respondents lack knowledge about IWMTS but perceive positive impacts on waste volume reduction and municipal waste management and little to no negative impacts on health, livelihood, and accessibility. Meanwhile, economic analysis showed that it is estimated to generate an annual revenue of PHP 11.986 million (USD 214,036) with yearly expenses of PHP 3.7 million (USD 66,071). These cash flows are expected to recover the overall capital outlay of PHP 48.14 million (USD 859,642). A net present value (NPV) of PHP 3.164 million (USD 56,500) and a 5.77-year payback period (PBP) were calculated through cost-benefit analysis. The environmental analysis revealed positive impacts on reducing the volume of wastes, water resources, and quality, odor and air quality, and soil and nutrients. Considering these, the study provided recommendations on project implementation to achieve sustainable waste management and circular economy in the municipality.

Cassandra Kyle Chamen | Emilia S. Visco
This study was conducted to assess the role of Butuanon River Watershed Management Board (BRWMB) in rehabilitating the Butuanon River in Cebu, Philippines. Data was gathered through key informant interviews with officials of the Board and a self-administered questionnaire for the members of the Board and was analyzed through descriptive and thematic analyses.Results showed that since the creation of the Butuanon River Watershed Water Quality Management Area (BRW WQMA) in 2014, the river’s biological oxygen demand (BOD) level has decreased. While the level has yet to meet the water quality guidelines of DENR’s Class D rivers, the Board’s initiatives like clean-up activities, information, education, and communication (IEC), and the relocation of informal settlers residing at riverbanks contributed to the improvement of the river’s water quality. The activities conducted by the Board strengthened the linkages with other stakeholders. The good working relationship among the stakeholders facilitated the convergence of their resources, making their efforts to rehabilitate the Butuanon River more coordinated and sustainable. Furthermore, Mandaue LGU, the chair of BRWMB, integrated its efforts in its Comprehensive Land Use Plan (CLUP) and the 10-year Action Plan of the BRW WQMA in its Butuanon River Rehabilitation Plan.Results revealed that the existence of BRWMB played a vital role in the Butuanon River’s rehabilitation, and such efforts are hoped to be sustained with the participation of the various stakeholders and formulation of policies to support all efforts of the Board.

Sandra S. Samantela | Karl Sam M. Maquiling
Leveraging the increase in property values emerges as an innovative financing method, enabling property owners and developers to contribute to collective benefit. The special assessment tax or special levy is a land value capture tool used to recover the costs of government infrastructure projects. Despite its long-standing existence in the Philippines’ Local Government Code, it is underutilized and its potentials as revenue sources have not been realized. This qualitative study combines extensive literature reviews and semi-structured interviews, including a self-assessment scoring of government staff in the cities of Metro Manila, citing perspectives and experiences in land taxation to examine institutional challenges in utilizing the special assessment tax. Findings reveal that institutional, financial, and technical capacity problems have prevented its utilization despite existing legal mechanisms. Moreover, there is a noteworthy gap in understanding and application at the local level, as the concept of land value capture is yet to be mainstreamed in local public finance. The discussions aim to inform cities and municipalities about the untapped potential of the special assessment tax as a viable revenue source for local development and the regulation of urban growth. Additionally, the study advocates for the importance of building capacities in land-based financing. It emphasizes the need for support and improvements in the current institutional arrangements of land valuation to address socio-economic inequalities.

In the Philippines, approximately 13% of adolescents become pregnant, resulting in 180, 916 births to girls aged 10-19. The study aims to understand the driving factors and challenges of adolescent teenage pregnancy. It also aims to propose a strategic intervention and implementation plan to address the rising number of teenage pregnancies. It was conducted in the 12 barangays who has the highest rate of teenage pregnancy in Lucena City. A total of 103 conveniently selected teenage mothers in the 12 barangays served as respondents of the study. The study is a descriptive research that utilized the qualitative method. Data were collected from interviews and focus group discussions. It was revealed that the impelling causes of teenage pregnancy were social media use, natural causes, pornography, peers, parents, chores, poverty, materialism, and female enticement. The respondents identified several challenges in terms of their social lives, health, schooling, and finances. Challenges in terms of social lives include access to public health facilities, child rearing, self-care, assistance in parenting, and limited supplies and services in Barangay Health Centers. The educational challenges include education disruption, financial hardships, the need for alternative forms of learning, and support from partners and immediate family to continue education. Meanwhile, for economic issues, financial hardship, future education plans, and plans to secure well-paid jobs were identified. Lastly, for social issues, the thematic analysis revealed the following: negative acceptance from the family and the community, normalizing being pregnant at a very young age, and feeling judged and becoming the center of gossip. The developed strategic intervention program includes three approaches: healthy sexuality, a comprehensive teenage program, and a societal approach. Parents and adults discomforted with their sexuality family approach, consistent adult involvement for the child, healthy communities, media responsibility, and reaffirming the importance of values and involvement of religious and other organizations may be targeted.

Liyao Zou | Liqing Zhang
Current research has revealed significant benefits of green space exposure (GSE) on psychological stress. However, few studies have explained the cumulative effects of GSE and how these effects vary across different demographic groups, such as gender and education level. This research aims to evaluate the long-term effects of GSE on psychological stress and heart rate variability (HRV) while examining how these effects vary across different demographic groups, such as gender and education level, utilizing Apple Watch data to provide a more objective measure of these effects. In a 6-week experiment, 43 college students were required to engage in GSE at least three times a week, each lasting no less than 10 minutes, based on their schedules. During the experiment, participants wore the Apple Watch continuously to collect physiological data automatically. This study demonstrates a significant reduction in emotional disturbance and notable changes in HRV amplitude following GSE, with variations observed based on gender and education levels. These findings underscore the substantial psychological health benefits of GSE.
