Development of fishpond automated fish feeder system prototype with GSM notification
Enanoria, Janea Rose L. (Davao del Sur State College, 2024)
Fish farmers rely on agriculture as their primary source of income, so they are looking for ways to produce higher quality of fish. Effective methods can help produce a lot of aquaculture products. The study aimed to develop a fishpond automated fish feeder system prototype with GSM notification for adult tilapia fish, addressing the persistent challenges of inconsistent feeding and insufficient awareness of water conditions. The system successfully monitors the status of water, including pH using the pH sensor and water temperature using the water temperature sensor, it also monitors the feed level in the tank using ultrasonic sensor and the time of feeding using real-time-clock (RTC). The study made it ideal for fish farmers. This reveals that using the prototype greatly enhances the agriculture field's performance, enabling the fish farmers to maintain stable growing conditions and the growth of their tilapia fish, as well as the successful sending of the readings from the sensor through SMS notification. Above all, the implementation of the fishpond automated fish feeder system prototype with GSM notification was successful in providing a convenient way for fish farmers to monitor their fish.
Water consumption and growth of spring onion (Allium fistulusom L.) under different nutrient solution depths in kratky hydroponics under shaded conditions
Dabalos, Marc Jay P. (Davao del Sur State College, 2024-06)
The study was conducted at Davao del Sur State College (DSSC), Brgy. Matti, Digos City, Davao del Sur, to investigate the effect of varying depths of nutrient solution on the water consumption and growth of spring onion. The experiment followed a Completely Randomized Design (CRD) with three treatments and three replications. The treatments were T1 (15cm depth of nutrient solution), T2 (10 cm depth of nutrient solution), T3 (5 cm depth of nutrient solution). The effect of the depths of nutrient solution was determined with regards to the water consumption, plant height, stem diameter, number of leaf, root length, number of shoots per plant and the temperature of nutrient solution. The gathered data was statistically evaluated using analysis of variance (ANOVA) at a significance level of 1% to 5% based on the results of the study, the nutrient solution depths showed no significant effect on the water consumption and growth response of spring onion (Allium fistulusom L.) and also to the nutrient solution temperature.
