Construction and Testing of an Improvised Leaf Electroscope

  • by Rex S. Rubidy (completed July 2015)

ABSTRACT

This study aimed to construct and test the improvised leaf electroscope (ILE) Physics Laboratory experiments. It was only limited on the construction and testing of ILE. The finished products replaced the existing electroscope and provide hands – on learning experiences to the students. The Improvised Leaf Electroscope was made of Erlen Meyer flask as chamber. Its major parts were the following: a) the metal rod which will serve as the stem and the knob, b) cork stopper which will hold the aluminum leaves mounted on the metal rod, and c) aluminum foil which will serve as the leaves. The materials needed are locally available and less expensive. Nine samples of ILE were constructed in order to test which samples can produce the highest approximate angle of deflection. Three various ways of test were made with three trials for each testing. Results reveal that copper rod is the best metal stem to use with an approximate measured angle of deflection of 26°. The appropriate length of the rod is 6 inches with 46° approximate measured angles of deflection. And the suitable width of aluminum leaves is 0.5 cm with 30° approximate measured angle of deflection. In order to improve the operation of the ILE, it is highly recommended to produce a good quality of plastic rod and woolen cloth in order to attain maximum results and not to depend on the imported rod and cloth.

Nutrient Composition and Antioxidant Property of Philippine Indigenous Vegetables

  • by Ilda G. Borlongan (completed August 2013)

ABSTRACT

This study determined the nutrient profile arid the anti-oxidant property of edible portions of 20 indigenous vegetables commonly consumed in the Philippines. The study conclude the most the vegetables are important sources of carbohydrates, proteins, fiber, minerals and fats. The vegetables contain minerals (Ca, P and Fe) that can supply our daily micronutrient needs and possesses an acceptable amount of anti-oxidants that can fight against many of the diseases as nutriceuticals. On the dry weight basis, the protein contents of the vegetables range between 18.4 to 35.4% with okra having the lowest and jute (saluyot) having the highest. The crude fat contents range from 0.11 to 8.5% with okra having the lowest value and malunggay having the highest. For fiber contents, the values range from 6 to 11.5% with taro (gabi) having the highest value. The digestible carbohydrate (NFE) contents of the vegetables are relatively higher in comparison with other nutrients. They range from 38 to 64%. The highest value is from okra and least is from malunggay and gabi. The ash contents range from 5% to 18 A with kolitis having the highest ash content and cowpea (paayap) and pigeon pea (kadyos) have lowest ash content. The moisture or water contents of the edible portion are high at (68 to92.5% aths’el highest ash content and cowpea (paayap) and pigeon pea (kadyo9s2)1.15aze) contents at 7.5 to 32%. Alugbati has the highest moisture conte content an therefore the lowest dry matter content Cowpea and pigeon pea have the highest dry matter content On a percent fresh weight basis, cowpea, pigeon pea and malunggay have the highest protein contents while okra and alugbati have the least. Results also reveal that malunggay has the highest crude fatamong content e fruit Among the leafy vegetable samples, malunggay has the highest fiber content while a in Kanto. or pod samples, kadyos has the highest fiber. The digestible carbohydrates are highest tops, malunggay and apat-apat among the leafy vegetables while among vegetable pod samples, highest digestible carbohydrates contents are found in kadyos and cowpea. Percent ash or mineral contents are highest in malunggay, kolitis with spine, violet lupo and ampalaya tops. As to the specific minerals, calcium (Ca) contents range from 103 to 2977 mg/ 100g dry weight with malunggay having the highest and kadyos the least Phosphorus (P) contents range from 320 to 610 mg/100g dry weight with apat-apat having the highest content Iron (Fe) contents range from 7.15 to 101 mg/ 100g dry weight with jute (saluyot) having the highest value and okra the lowest The antioxidant properties of the different indigenous vegetables measured as percent free radical scavenging activity and total polyphenolics are relatively high. The antioxidant activities of all raw leafy vegetables and okra (75.7 to 92%) are higher than those of the blanched (64 to 83.4%) and boiled (59 to 80.1%) counterparts. This indicates that blanching and boiling greatly influence the loss of antioxidant components in leafy vegetables. Blanching decreases the activity from 5 to 15% while boiling decreases the acbvity by 10 to 25%. For the vegetable pods, no significant differences in anti-oxidant activities are observed in the raw, blanched and boiled samples indicating that blanching and boiling do not affect the anti-oxidant property of these vegetables. Processing affects content, activity and bioavailability of bioactive compounds and therefore health promoting capacity of vegetables depends on their processing history. This aspect should be strictly considered to obtain the optimum nutriceutical benefits from these vegetables. The findings on the nutriceutical importance of these indigenous vegetables to humans should provide a motivation for exploring their horticultural potential.

Impact Survey on the CPU Integrated Outreach Activity for Barangay Ilongbukid, San Rafael, Iloilo

  • by Aries Roda D. Romallosa, Hope G. Patricio and Margen A. Java (completed June 2016)

ABSTRACT

This study evaluated the impact of Central Philippine University (CPU) outreach interventions and activities for Brgy. Ilongbukid and adjacent communities in San Rafael, Iloilo based on recently obtained cross-sectional data vis-a-vis the 2006 and 2012 baseline results. The “post-test” or the “one shot” survey design and focus group discussion with toy stakeholders were done to measure the qualitative and quantitative changes brought about by outreach implementation. Results showed that the awareness level on the CPU outreach activities was high but availment of the services among the respondents was low (18.0) since only households with children enrolled at Ilongbukid National High School were reportedly prioritized. Those who benefited front the outreach activities claimed definite satisfaction or satisfaction. Most of the respondents (90.6%) considered the outreach activities to be important. The great majority of the respondents (94.0%) believed that the CPU outreach activities had positive impact in their barangays. Specifically, the residual earnings from the swine chain dispersal project helped finance the children’s education, contributed to house improvement, provided basic needs, and increased household income. It is, therefore, recommended that the outreach activities should be extended to other barangay residents for inclusive growth.

Tracer Study for the CARES Graduates from 2006-2011

  • by Reynaldo N. Dusaran (completed October 2015)

ABSTRACT

This tracer study was conducted to gather relevant information as to the employment of CPU College of Agriculture, Resources and Environmental Sciences (CARES) graduates from 2006 to 2011 and compare the present findings with the previous findings. Data mere collected through a self-administered questionnaire among 51 out of the 82 (62.2%) graduates of the CPU CARES from 2006 to 2011. Results revealed that except for the single civil status of the respondents in the present study (2006-2011) and married in the first survey (1995-2005). the respondents in both surveys were males, not more than 30 years of age, from Region VI, specifically from Iloilo and residents of municipalities. A greater proportion of respondents in the present than the first survey had acquired professional skills but a greater proportion of the respondents in the first survey had passed any professional examination than those in the present survey. A greater proportion of the respondents in the present survey than in the first survey had attended any training and had advance studies and were employed, however, a much greater proportion of the respondents in the first than in the present survey were regular or permanent. A greater proportion of the respondents in the present survey are working abroad and claimed their present employment as their first job. In both surveys, the respondents claimed that their first job is related to their course. Most of the respondents in the first survey stayed in their first job for one to six months only while most of those in the present survey stayed in their first job from one year to less than two years. In both surveys. the respondents were able to find their first job recommended by someone within six months with a greater proportion of respondents in the present than in the first survey finding their first job as recommended by someone and within six months. The level of the first and present job of the respondents in both surveys is more or less the similar as professional, technical or supervisory. The initial gross monthly earnings of the respondents in the present survey are higher than those in the first survey. In both surveys, the respondents claimed that their curriculum was relevant to their first job and the major competencies they learned in college that they find very useful in their first job included technical skills and human relations skills plus communications skills in the first survey and critical thinking skills in the present survey. Generally, they did not make any suggestions to improve their course curriculum and their program. The respondents in both surveys took their course at CARES because of the quality of its graduates as seen from its alumni, known standard of instruction and performance of its graduates in the field. Among the five major program components, in both surveys, farm practice had the highest mean significance rating while extension had the lowest rating. Overall mean significance rating was slightly higher in the first survey than in the present survey. Among the nine different services/areas of the university/college, in the first survey, highest mean satisfaction rating was on library while the lowest satisfaction rating was on laboratory. In the present survey, highest mean satisfaction rating was on faculty while the lowest rating was on physical plant. The overall mean satisfaction rating has improved.

Biomass Yield of Moringa Oleifera as Influenced by Plant Density and Harvest Population

  • by Manuel C. Palada, Hope G. Patricio and Diaden E. Garcia (completed June 2015)

ABSTRACT

This study was conducted to determine the of biomass yield of Moringa (Moringa Oleifera) as influenced by plant spacing and frequency of harvesting. Moringa plants were grown at four plant spacing and densities: a) 1m x 1m (10,000 plants per hectare-pph); b) 1 m x 0.5 m (20,000 pph); c) 0.9 m x 0.37 m (30,000 pph) and d) 0.5 m x 0.5 m (40,000 pph), and harvested at three frequencies: 4, 6, and 8 weeks. The field trial was established in a factorial randomized block design with three replications. Moringa seeds cultivar PKM-1 were directly sown in various plots on December 12, 2013. Optimum soil moisture for germination and seedling growth was maintained and complete fertilizer was applied at one tablespoon per plant three weeks after emergence. Seed germination and plant height were recorded on periodic basis. Initial harvest for all treatments was perform 116 days after sowing. Thereafter, harvesting frequencies were followed according to treatments. Results showed that the effect of plant density, harvest frequency, and interaction between plant density and harvest frequency were significant. Overall, fresh leaf biomass increased as plant population increased from 10,000 to 40,000 pph. There was a positive correlation between plant density and biomass yield. Similarly, the longer the harvest frequency the higher was leaf biomass. Based on this study and growing conditions, the optimum plant density for fresh leaf production can be from 20,000 to 30,000 pph. Although leaf production was low at 4-week harvest interval, this frequency may be desirable when there is a need for monthly supply of Moringa raw material for processing into leaf powder and other by-products.

Design and performance evaluation of a jack-driven briquetting machine for briquette production

  • by Aries Roda D. Romallosa (completed October 2014)

ABSTRACT

This study was conducted to design and evaluate an improvement version of a briquetting machine that utilizes a hydraulic-type bottle-jack for better compression in producing briquettes. The machine can compact 16 cylindrical (with a hole at the center) briquettes resting or about 200-240 pcs/hr. The jack creates the needed pressure by thrusting the molders up to fully compact the materials. With the aid of one spring each both sides, which jointly holds together the molder and jack flooring supports, the piston of the jack when loosened is pulled back to its normal position allowing a semi-automatic type of operation. The briquettes produced by the machine functioned well as fuel when subjected to cooking and boiling tests indicating its potential as alternative source energy. This was also highlighted by a higher percentage (81%) of willingness by waste reclaimer-respondents to buy them as fuel for various cooking and heat applications. The production cost per hour for briquettes ranged from about Php23 to Php 26. Leveling-up of operation may even increase production giving an annual potential earnings of about Php46,000.00 to Php85,000.00. The quality of the three briquettes produced slightly varied and some of the parameters analyzed like bulk density, heating value, moisture, N and S closely met or have met the requirements of DIN 51731.

Genotype-by-Environment Interactions of Traditional Chicken (Gallus gallus domesticus L.) Groups in Western Visayas, Philippines

  • by Jaime C. Cabarles, Jr. (completed March 2012)

ABSTRACT

There are three major groups of traditional chicken in Western Visayas, Philippines namely: Bisaya I, Bisaya II, and Jolo chickens. This study was conducted to determine the interactions of these groups with environmental parameters in the expression of production performance. This study employed purposive sampling covering the provinces of Aklan, Antique, Guimaras, Iloilo, and Negros Occidental A total of 270 raisers were surveyed and 810 chickens were characterized. Collected data were analyzed using correlation and general linear model. Results showed highly significant (P<0.01) correlation between mean daily temperature with relative humidity (r=-0.310), rainfall (r=-0.634), and wind speed (-0.341), and relative humidity with rainfall (r=0.275) and wind speed (-0.301). Jolo chickens had heavier (P<0.01) adult weight (1.65 kg) than Bisaya I (1.238 kg) and Bisaya II (1.504 kg). These chickens can be raised in any slope and production systems without significant effects in their performance in terms of hatching percentage and survival rate. On the other hand, only the Bisaya I adult liveweight becomes lighter when grown in warmer areas.
