Item PATH FIT 1: Movement competency trainingJuezan, Gideon I.; Eta, Mary Joan D.; Juezan, Ivan Jee I. (Dreamer Publishing Services, 2025)Item Smart office document management system with descriptive analytics and SMS alertsReyes, Joana Rose Mae U.; Origines, Domingo V., Jr. (Universitas Duta Bangsa Surakarta, 2024-09-24)This study aimed to address the inefficiencies of manual document submission and deliver a user-friendly dashboard that presents submitted document data through various visualizations and data analytics. The approach enhances decision-making processes, operational efficiency, communication, and collaboration within organizations. Descriptive data analytics methodology was employed to effectively summarize and present key data points. The project also adopted the Rapid Application Development methodology during its development. As a result, the project received favorable evaluations from its assessors, achieving high overall mean scores of 4.17 for functionality, 3.95 for reliability, and 3.98 for usability. Consequently, by integrating descriptive data analytics and SMS notification system, the implementation notably benefited the Human Resource Management Office of Davao del Sur State College by providing a Web System with dashboard equipped with visualizations such as count metrics, bar graphs, and tables. Additionally, the system facilitated seamless information updates, empowering administrators to make evidence-based decisions and identify trends within their data.Item Mangotayo!: A sustainable smart agriculture model for mango industry upliftment in Davao del Sur, PhilippinesPerito, Rhea Mae L.; Surdella, Karl Vincent A.; Restauro, Richie Boy D.; Panaligan, Nel R.; Origines, Domingo V., Jr.; Aquino, Eduardo F.; Aguilar, Razel Ann G. (Science Research Society, 2025)Mango production in the Philippines ranked seventh globally, producing high-quality mangoes and supplying different countries. However, from 2000 to 2020, the Philippine mango sector saw a steady reduction in all industry performance metrics, such as production volume, productive area, yield per unit area, and yield per tree. Furthermore, the export of mangoes is not doing as well as in earlier decades. Other problems encountered by many farmers specifically small-scale farmers are lack of pest control and nutrient management, poor induction and flowering intensity, the lack of farm-to-market roads, and low farm-gate prices. Responding to these issues, the Mango Tayo! Program developed an AI-based Smart application for mango production management, utilizing cutting-edge technologies in smart agriculture. Thus, community engagement and activities were conducted to capacitate the women and men mango growers and contractors in Digos City using the developed technology. The program was found to be successful in achieving its objectives—enabling the community partners to use cutting-edge technology in farming.Item Kappaphycus dripping enhance seed germination and production of hybrid rice (PSBRc72H – Mestizo 1)Agudera, Juan P., Jr.; Caballero, Graciela L.; Revilla, Nila Nanette S.; Gliocam, Mariz (Southern Philippines Agri-Business and Marine and Aquatic School of Technology, 2013)This study was conducted in SPAMAST-CAS, Matti, Digos City and at New Ilocos, Magsaysay, Davao del Sur. The general objective of the study was to evaluate the germination, growth and yield of PSBRc72H as influenced by different levels of Kappaphycus Drippings (KD). Findings of the study revealed that hybrid rice seeds soaked for 12 hours with 20 ml of KD per liter of water enhanced germination to 86.67%. KD as foliar fertilizer improved the agronomic characteristics such as plant height in cm (45 DAT), number of tillers per hill (60 DAT) and number of productive tiller per hill; and yield components such as number of filled spikelets per panicle and 1,000 seed weight (g) thereby increasing the grain yield (t/ha) of hybrid rice. KD did not influence the length of panicle (cm).Item Distribution and ecology of metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 in Mindanao, PhilippinesPatano, Romeo R., Jr.; Mohagan, Alma B.; Ponce, Amy G.; Guiang, Maria Melanie M.; Malinao, Rodceal; Pescuela, Gretl Rae P.; Coritico, Fulgent P. (Department of Science and Technology, 2023-02)Metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 is a Mindanao-endemic species known only in Davao del Sur. Here, we recorded the species first in Bukidnon and the Cotabato region. Moreover, we also provide ecological notes of the species specifically the identities of its food plants, description of its habitat, and potential threats.Item Locating-hop domination in graphsCanoy, Sergio R., Jr; Salasalan, Jemma P. (Kyungpook National University, 2022)A subset S of V (G), where G is a simple undirected graph, is a hop dominating set if for each v ∈ V (G) \ S, there exists w ∈ S such that dG(v, w) = 2 and it is a locating hop set if NG(v, 2) ∩ S 6= NG(v, 2) ∩ S for any two distinct vertices u, v ∈ V (G) \ S. A set S ⊆ V (G) is a locating-hop dominating set if it is both a locating-hop and a hop dominating set of G. The minimum cardinality of a locating-hop dominating set of G, denoted by γlh(G), is called the locating-hop domination number of G. In this paper, we investigate some properties of this newly defined parameter. In particular, we characterize the locating-hop dominating sets in graphs under some binary operations.Item Enhancing herbage growth, yield and quality of stevia (Stevia rebaudiana bertoni) using bio-organic nutrients in varied soil mediaCalapardo, Mara Jean Marielle; Manigo, Bryl I. (Penerbit Universiti Kebangsaan Malaysia, 2024)The present method of stevia propagation is still insufficient to meet its increasing demand. Moreover, the use of organic inputs as substitutes for inorganic fertilizers to improve soil quality and productivity is also desired. In this study, the effects of bio-organic nutrients and different growing media compositions on Stevia’s herbage growth, yield and quality were determined. A completely randomized design was used with 20 rooted stem cuttings per replication at one cutting per potting bag, laid in a 4 × 4 factorial arrangement. Growing Media (garden soil alone [GS]; GS + rice hull [RH]; GS + vermicompost [VC]; and GS+RH+VC) served as factor A while bio-organic nutrients (fermented fruit juice [FFJ]; vermi tea [VT]; seaweed tea [ST] and control) as factor B. There were 16 treatment combinations replicated four times. Results showed that GS+RH+VC consistently improved the survival rate, plant height, leaf and shoot count per plant, weight (fresh and dry), and herbage yield of Stevia. Furthermore, VT boosted the herbage yield and visual quality. In terms of interaction effects, plants grown in garden soil mixed with vermicompost (GS+VC) with VT application developed more leaves than other treatment combinations. Hence, these bio-nutrients and growing media composition significantly enhanced the production of Stevia.Item Seaweed-based dripping stimulates root growth of dragon fruit (Hylocereus undatus [Haw.] Britton & Rose) stem cuttingsPotente, Mayalene M.; Manigo, Bryl I. (Penerbit Universiti Kebangsaan Malaysia, 2023)Developing a solid root system is essential in dragon fruit propagation not only for securing the succulent stem but also for facilitating the absorption of water and essential minerals from the soil. However, dragon fruit stem cuttings normally develop good root system for about 4-6 months after planting. There are commercially available growth hormones which hasten rooting, but these are relatively expensive. Hence, alternative hormones from natural materials that possess the ability to stimulate rooting are extensively explored. The efficacy of seaweed-based drippings (SD) as potential rooting bio-stimulant for dragon fruit cuttings were evaluated under nursery condition. Branch cuttings (30 cm long) were soaked at 6, 12 and 18 h at the rate of 50 mL, 100 mL and 150 mL SD per liter of water (H2O), with H2O, and ANAA (5 mL/L of H2O) served as positive and negative control treatments, respectively. There were 18 cuttings in each experimental units, replicated thrice and arranged in a 3 × 5 Completely Randomized Design (CRD). Results showed that 12 h soaking initiated more and longer roots and shoots. In addition, it appeared that the application of a solution containing SD at 100 mL/L of H20 resulted in the development of numerous and longer roots and shoots, a larger number of lateral roots, and a greater root-shoot ratio than other treatments. Furthermore, application of SD at 100 mL/L of H20 through dipping for 12 h developed more lateral roots compared to other treatment combinations. In conclusion, it can be inferred that the presence of phytohormones, such as auxins, in seaweed concentrates has the potential to effectively stimulate root formation in pitaya.Item Identifying suitable sites for pump irrigation system from open source and shallow tube well in selected areas of Davao Del Sur through geographic information system-based water resources assessmentTrondillo, M. J. F.; Generallao, I. C .; Valleser, R. A. R.; Lopez, M. T.; Janson, A. Z., Jr.; Bejarasco, J. A.; Toriales, I. R., Jr. (2019-05)This paper features the Geographic Information System (GIS) in identifying suitable sites for small scale irrigation projects (SSIP) particularly pump irrigation system from open source (PISOs) and shallow tube well (STW) through water resource assessment. The development of GIS-based assessment model for SSIP and resource map in aid of SSIP planning and development is limited in some municipalities. To develop a reliable GIS-base framework, the ArcGIS tool and spatial method was used in compiling specific factors with field analysis and developing regional resource map for SSIP. The results showed that STW in Digos City and Municipality of Hagonoy is 117 units and 17 units respectively. The average water depth in existing STW is within the 6.5 meters with capacity to irrigate 3 to 5 hectares per unit, low investment with high water use efficiency and simple to operate. It was found out that most STW is provided by Department of Agriculture-Regional Field Office XI and Local Government Units. The STW is suitable for Digos City with an area of 379.32 hectares. While the PISOS were identified with different range of pump horsepower. There are 10 units of PISOS in Digos City and 15 units in Hagonoy mostly provided by National Irrigation Administration-XI. It was found out that in Digos City the 1,855.53 hectares are highly suitable and 14,377.55 hectares are not suitable for PISOS. The results of this study may assist the decision making processes for planning and development of SSIP using the developed protocol and tools for different purpose in agricultural production in Davao del Sur, Region XI and the whole country.Item Revisiting domination, hop domination, and global hop domination in graphsSalasalan, Gemma; Canoy, Sergio Jr. R. (New York Business Global, 2021)A set S ⊆ V (G) is a hop dominating set of G if for each v ∈ V (G) \ S, there exists w ∈ S such that dG(v, w) = 2. It is a global hop dominating set of G if it is a hop dominating set of both G and the complement G of G. The minimum cardinality of a hop dominating (global hop dominating) set of G, denoted by γh(G) (resp. γgh(G)), is called the hop domination (resp. global hop domination) number of G. In this paper, we give some realization results involving domination, hop domination, and global hop domination parameters. Also, we give a rectification of a result found in a recent paper of the authors and use this to prove some results in this paper.
