    The growth and yield performance of oyster mushroom (Pleurotus ostreatus Fries) using fish wastewater as fertilizer
    Arroyo, Karen T. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-04)
    Oyster mushroom, Pleurotus ostreatus, is an edible wood-inhabiting fungi that continues to gain popularity in the Philippines, as well as in other tropical countries. With the use of modern technology, this mushroom can be grown in the Philippines, provided sufficient moisture is present. Its present cultivation is limited, perhaps due to insufficiency of planting materials and the limited knowledge about its culture. The main objective of the study was to establish the possibility of the replacement of urea, the commonly used fertilizer for mushroom cultivation by fish wastewater. The study also aimed to compare the effects of different concentrations of fish wastewater on the growth of mushrooms and determine which treatment produced the best results. A total of five groups were used: two control groups (positive and negative - using urea and water, respectively) and three experimental groups, the latter with different concentrations of fish wastewater serving as alternative fertilizer (A: 10%, B: 20%, C: 30%). Fruiting bags were inoculated with oyster mushroom spawn, and after a month of incubation, the growing mushrooms were assessed using the parameters of number, weight, length, and diameter. Results showed that the weight of oyster mushrooms was heaviest when the substrate was sprayed with plain water. However, the number of mushrooms harvested, their length, and the width of the pilei were not affected by spraying the substrate with urea or moistening these with up to 30% fish wastewater. The conclusions reached were: 1) when using sawdust as substrate for oyster mushroom cultivation, it is best to simply use water to maintain the moisture of the material; 2) sawdust used in combination with low concentration of fish wastewater (10%) can result in good production; 3) neither nitrogen nor urea may be a critical factor for the growth of oyster mushroom on sawdust; and 4) high amount of phosphorus and low potassium content of fish wastewater are favorable for oyster mushroom growth.

    Baranugun kang tarangban: A Shounen Manga
    Bagarinao, Andrea F. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2009-04)
    Manga is a very popular form of popular literature. It is the Japanese term for comics, but outside Japan, "manga" is exclusively used to refer to Japanese comics or Japanese-style comics. Shounen manga are comics intended for male readers. They focus on action, adventures and development of male heroes. The Rescue, the latter part of the third courting adventure consisted in The Epic of Labaw Donggon, was enhanced using styles and concepts of shounen manga. The themes and characters, which are very important elements of manga, involved in the epic and the story itself were explored and improved to create the shounen manga, Baranugun kang Tarangban.

    A benchmark survey on the cyanide and protein content in the leaves and roots of cassava (Manihot esculenta Crantz) in Iloilo
    Bacolod, Hanny Joy C. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2006-04)
    The cyanide and protein content of the roots and the leaves of the cassava samples were determined. Samples were taken from five locations, namely, Mambatad, Miagao; Poblacion, Lambunao; Ambarihon, Tubungan; Naclub, Miagao; and Calampitao, Miagao. This study shows the levels of cyanide and protein in the roots and leaves of the cassava samples from the five selected locations in the province of Iloilo only. It does not establish any concrete conclusion on the cyanide and protein content of the cassava in Iloilo. Based on the results, the amount of cyanide varies among parts of the plant with an average of 229 ppm in the leaves and 100 ppm in the roots. It also varies among varieties in the same location, the white root variety having 125 ppm cyanide in the roots and 202 ppm in the leaves, while the yellow root variety has an average of 58.2 ppm cyanide in the roots and 263 ppm in the leaves. Different locations also have different levels of cyanide. Cyanide content also decreases in the roots as the period of storage is prolonged. The level of cyanide in the white root variety from Lambunao decreased by 17.1% on the 2nd day and 61.5% on the 3rd day, while the yellow root variety, also from Lambunao, decreased by only 4.3% on the 2nd day and 30.1% on the third day. Total soluble protein in the leaves (0.12%) of the samples is higher than in the roots (0.11%) . Among the roots, the amount of protein varies. It was found out that there is a significant correlation (0.750 at 0.05 level) between the amount of protein in the roots and that in the leaves of the samples.

    Treatment of Vibrio harveyi-infected Penaeus monodon using Alibutbut (Tabernaemontana pandacaqui Poir.) plant powder
    Bacaling, Marivic T. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2005-04)
    The cytotoxicity test of crude methanolic leaf extract using Brine Shrimp Lethality Assay revealed that Alibutbut (Tabernaemontana pandacaqui Poir.) is safe to use in treating vibrio-infected penaeid shrimps. The effectiveness of the alibutbut powder against vibriosis was examined through the determination of the post-larvae 20 (PL 20) penaeid shrimp mortality and the water microbial assay after 48 hours. Percent penaied shrimp mortality (0-6.67%) and microbial count (2.91 x 10^4- 3.26 x 104 cfu/mL) of the plant treatments were significantly lower compared to the negative control (no treatment) that exhibited 50% penaeid shrimp mortality and a microbial count greater than 6.00 x 10^4 cfu/mL. The results of the experiment showed that Alibutbut plant powder is indeed effective in controlling Vibrio harveyi bacteria.

    Cytotoxicity and anti-vibriotic activity of Noni as an ethnobotanical
    Arrojo, Marley C. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2005-12)
    The crude methanolic extract of Acacia, Alibutbut, Bayabas, Biab, Botolan, Bulobitu-un, Buyo, Kamunsil, Kasla, Kayos, Langka-langka, Noni, Pasaw, Sampaguita, Tabong, Talisay, Yellow bell, were bioassayed for their cytotoxicity using brine shrimp nauplii assay. Among the plant extracts, Noni gave the highest LCso equal to 943.329 pg/mL. Noni was the least toxic among the plants tested and its crude methanolic extract was found to have activity against V. harveyi with an anti-vibriotic index of 0.256. Sequential extraction using solvents with increasing polarity gave fractions that exhibited anti-vibriotic property but the more polar ethyl acetate fraction gave the highest anti-vibriotic index of 0.513. It appears that the anti-vibrio constituent is polar. Using VLC, the ethyl acetate fraction was further separated into eighteen fractions which were in turn pooled into five fractions, Fa, Fb, Fc, Fd, and Fe based on their TLC profile. Anti-vibriotic activity of each fraction was determined. Fraction Fa has the highest anti-vibriotic index (0.192) but this is much lower than 0.513. There must be some synergy among the polar constituents that exhibited a higher anti-vibriotic index in the ethyl acetate fraction compared to fraction Fa. Based on several color reactions, ethyl acetate fraction may contain any of the following plant metabolites such as tannins, saponins, phenolic groups, conjugated double bonds, flavonoids, sterols, terpenes, except alkaloids.

    Alvizo, Marjorie V.; Laura, Cecille R. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)
    Generally, this study aimed to evaluate or assess the profitability of van operation in Miag-ao, Iloilo. It specifically dealt with the cost and return structures of the said business. The study was conducted in the municipality of Miag-ao, which is one of the towns in the province of Iloilo. There were 11 respondents who are all van operators and at the same time members of the Miag-ao Association of Van Owners and Drivers, Inc. (MAVAD). Two of them owned or operate two vans, so in the data presented there were 13 vans. A one-shot survey using recall method was used as a source of data. An interview schedule was also utilized in gathering the needed data for the study. In analyzing the data, frequency distribution, percentage, ranking and weighted mean were employed. Likewise, cost and return analysis was used to determine the profitability of the van operation. Results of the study showed that almost half of the respondents have an age range of 30-40 years. Majority (73%) of them were males and already married. All van operators earned college degrees and have well-paying jobs. Roman Catholic was the dominant religion and most of them have or belong to medium family size. The cost and return analysis of the study showed that the average initial investment in the van operation was P 238,000. The total annual operating cost was P 434,366. Forty nine percent of it was paid for the salaries and allowances of the laborers. The annual gross revenue was P 505,210 with a net income (or pure economic profit) of P 70,844. Rate of return on investment was 30% and it will take 3.4 years for the business to recover its initial capital outlay. Based on the results presented, with positive net profit and gross revenue it is profitable to engage in this business venture.

    Fourier transform -infrared-attenuated total reflectance spectroscopy in conjunction with the principal component analysis and agglomerative hierarchical clustering to classify virgin coconut oil and other edible oils
    Aloba, Eugene J. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2006-04)
    This work investigates the potential of Fourier Transform Infrared-Attenuated Total Reflectance (FTIR-ATR) Spectroscopy in conjunction with Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) to classify virgin coconut oil (VCO) from other different edible oils in the test set. Among the PCA types, Pearson produced the best biplot graphs that showed both the separation of VCO and coconut oil (only in one group) from other oils, and the separation of VCO and coconut oil (CCO) into two distinct groups using the fingerprint region of the spectra. Kendall dissimilarity/Ward’s method successfully clustered VCO and CCO as separate classes using the same region of the spectra. These results showed that the highest percent variability in the spectra of different oils occurs in the fingerprint region, and hence where spectroscopic classification of oils can be performed best.

    Perceived body image of female college students
    Almonte, Darby April Gaye Q.; Tinsay, Shiela Mae B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)
    The study aims to describe the perceived body image of female college students. Specifically, it wants to find out the activities of female college students relative to their body image; their exposure to the mass media in terms of enhancing body image; and to find out the influence of mass media exposure to their perceived body image. The study was conducted in the College of Arts and Sciences, University of the Philippines in the Visayas, Miag-ao, Iloilo. Sixty respondents were obtained from the population of Social Sciences students using the fishbowl method of simple random sampling. The Body Parts Satisfaction Scale (Spainhour, 2000), together with a set of questions developed by the researchers, were used in gathering the data. Generally, the results showed that the female college students have a positive perception of their body image. Also, the female college students do not engage in any activity related to body image, such as dieting and exercising. Lastly, they are well exposed to the mass mediated messages about body image in the television and the magazine but they are not negatively influenced by those messages, that is, they neither compare their bodies with nor do they want to look like the models in television and magazine.

    Television viewing patterns of children in a rural community
    Allones, Christine Marie G; Montalvo, Nica M. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-03)
    The general objective of the study is to find out if there is a relationship between TV viewing patterns of children in a rural community and the socio-demographic characteristics such as age, sex, and the parents’ educational attainment. Specifically, it aims to (1) describe the socio-demographic profile of the respondents; (2) determine if there is a relationship between children’s age and their TV viewing pattern; (3) determine if there is a relationship between children’s sex and their TV viewing pattern; (4) determine if there is a relationship between parents’ educational attainment and TV viewing pattern. The data analyzed in this study are obtained through conducting guided interviews with 80 children. The areas included by the researchers in the study are the hours and days of TV viewing of children, their program preferences, their sleeping time, and the frequency of scolding of the parents. It was found that majority of the respondents are 10-12 years olds, males, and have parents who have both high educational attainments. Results reveal that majority of respondents spend between one to five hours watching television everyday. Their usual sleeping time is before or at nine in the evening. Nonetheless, many are scolded for watching television on weekdays but never on weekends. The results of the study concluded that there is a significant relationship between sex and hours of television viewing while age and parent’s educational attainment have no significant relationship in the hours of television viewing. There is no apparent difference between the number of hours of television viewing and the age and parent’s educational attainment. The only difference is that majority of male children watch television for one to five hours a day, while most female children watch more than five hours of TV viewing. Thus, there is a significant relationship between sex and hours of television viewing. On the other hand, there is no significant relationship between the days of TV viewing and the socio-demographic characteristics of the respondents. The researchers recommended that a similar study could be conducted in an urban area, covering a bigger sample size, and using other set of variables that can affect the TV viewing patterns of children. Other researchers are also encouraged to explore the field since there are not so many studies about them in the country.
