Sombiro, Mae Joy A.
The study was conducted to design, fabricate and evaluate the performance of the hydraulic diaphragm pump for irrigating water. The fabrication was done in Molo, Iloilo City and the performance testing and evaluation were conducted at the Jalaur Dam located in Brgy. Moroboro, Dingle, Iloilo. The set-up consisted of the site of the source of water (dam), drive pipe, impulse valve, diaphragm body and pump end. The diaphragm body was composed of rubber diaphragm, spring, rod and gasket cup. The pump end was composed of suction valve, suction pipe, delivery valve and delivery pipe. The operation of the hydraulic diaphragm pump started when the water flowed to the drive pipe creating a water hammer effect causing the impulse valve to open or close. When the impulse valve closes, pressure is directed to the diaphragm which caused the plunger to force water to the delivery pipe. Results revealed that for a maximum vertical lift of 6 m, an average discharge flow rate of 0.054 Ips (194.4 li/hr) was recorded giving the pump a power generation of 3.167 watts. The investment cost is PHP25,000.00 for the fixed and variable costs of PHP45.89/day and PHP200.00/day, respectively, giving a total cost of PHP245.89/day. Furthermore, computations revealed that the hydraulic diaphragm pump may incur an operating cost of PHP0. 16/li.

Porque, Edilberto P.
This study was conducted at Brgy. Poblacion, New Lucena, Iloilo on December 5, 2020. Ham evaluation was done at CPU Centennial Village, Pavia, Iloilo. This study was conducted to determine the acceptability of smoked chicken ham enhanced with different plant leaves as additives for smoking materials. There were 3 experimental treatments composed of 3 different leaves namely lemongrass, tamarind, and guava leaves. Each treatment was replicated three times. The smoked chicken ham was evaluated by a taste panel according to a set of criteria. Members of the taste panel were given 10 to 15 minutes to evaluate and rate the samples, food action rating and descriptive analysis. Results revealed that as to the taste preference, smoked chicken ham enhanced with lemongrass, tamarind and guava leaves were rated as more preferred. Furthermore, ANOVA showed no significant differences on the color, saltiness and taste preference of smoked chicken ham. On the other hand, producing smoked chicken ham with tamarind and guava leaves cost less than using lemongrass leaves as additives for smoking material. The commercial ham currently sold in the market costs Php 450.00 per 1 kg which cost Php 198.24, Php 238.24 and Php 245.74 more costly than chicken ham smoked with lemongrass, tamarind, and guava leaves, respectively. Based on the results, it can be concluded that lemongrass, tamarind, and guava leaves can be used as additives for smoking materials in chicken ham given its palatability and acceptability in terms of color and taste preference.

This study was conducted at the present location of the Project in Brgy. Hamungaya, Jaro, Iloilo from May to August 2018 evaluating the actual field performance of the Solar-Powered Irrigation Project The basic components of the Solar-Powered Irrigation Project are: submersible solar pump, solar power modules, control unit or level controller, pipes, mounting structure, steel gates and reservoir. It has the major functions of pumping irrigation water, improving access to water and having no greenhouse gas emissions. This Project was field tested for 5 consecutive days each during the dry and wet seasons giving an actual discharge of 1.634 li/sec and 1.668 li/sec, respectively. The minimum pump efficiency used was 40%. The water horsepower generated for dry and wet seasons were 0.968 Hp and 0.988 Hp, respectively, while the brake horsepower was 2.41 Hp for dry season and 2.46 Hp during the wet season. Results of the performance test of the Solar-Powered Irrigation Project showed that it satisfied the required flow rate of 1.4 li/sec and 0.8 li/sec for the operation of dry and wet seasons, respectively. The 2 Hp rating of the existing pump was less than the brake horsepower computed using minimum pump efficiency which could be increased when certain factors will be applied. Furthermore, the number of solar panels on the design satisfactorily supplied the required power to run the pump efficiently both during the dry and wet seasons.
