Business Strategies of Micro, Small, and Medium Enterprises in Response to the COVID-19 Pandemic
No full textThe COVID-19 pandemic health protocols have adversely impacted the economic profit and business operations of micro, small, and medium enterprises (MSMEs). This study aimed to evaluate the business strategies employed by MSMEs as they are facing the public health crisis in Bato, Leyte, Philippines. A random sample of 200 MSMEs were surveyed using a structured questionnaire. Some descriptive statistics and Chi-square test for independence were used to summarize and determine the relationship among variables, respectively. Results showed that dominantly more of the MSMEs are operated by owner-managers during the pandemic. On average, most (97.5%) of the enterprise operating are micro and operates for about 3 years. About 63.5% of the MSMEs during the pandemic has adopted a new strategies to cope with COVID-19’s negative impact and most of them are micro in nature. The major business strategies adopted to survive the adverse impact of the pandemic are as follows: following health protocols (50%), finding suppliers in nearby towns (33.8%), seeking alternative sources (26%), increasing prices of items sold (24.5%), and local outsourcing (22.5%), among others. It is concluded that age is a significant factor in implementing business strategies (p-value<0.019). This implies that owner-managers with higher age (average is 40 years old) are more likely to adopt business strategies. Moreover, as they are experiencing vulnerability to the pandemic such as economic profits being significantly reduced, then they are more likely to implement strategies (p-value<0.001). Short and long term plans are considered in order to survive and sustain its business operations. Hence, the study recommends that the government should help and enhance the capability of enterprises in managing risk as well as ensuring MSME’s continuity amidst the pandemic
Another look at sensory attributes of broiler chickens fed with non-fermented and fermented diets
No full textThis study aimed to assess the sensory attributes and general acceptability of steamed meat of broiler chickens fed with non-fermented (control) and fermented diets. The study used water, water + coco vinegar, and water + RPL8+AKE probiotic as fermenting causal agents. A total of thirty (30) breast carcass (steamed at 100oC for 10-15 minutes) samples per treatment at five grams (5g) per sample were utilized for evaluation. A group of thirty trained taste panelists composed of Food Technology students assessed the sensory attributes using the quality score and Hedonic scale sheets. Descriptive statistics were used in the sensory evaluation, and analysis of variance (ANOVA), and multiple comparison test using Tukey’s honestly significant difference (HSD) test was used to compare the treatment means of the sensory attributes of the steamed meat samples in terms of skin color, flesh color, aroma, texture, taste, and general acceptability. The rating scores on skin colors (p-value=0.050), and texture (p-value=0.013) of steamed meat of broiler chickens fed with non-fermented and fermented diets were significantly different at a 5% level. Results revealed that the fermented diets have improved the broilers\u27 skin colors (yellowish cream) and improved the texture quality of meat (moderately firm). Based on ANOVA, there is no significant difference observed in the descriptive scores in relation to flesh color (p-value=0.171), aroma (p-value=0.621), taste (p-value=0.723) and general acceptability (p-value=0.491). However, the steamed carcass of broiler-fed fermented diets (coco vinegar and probiotic) is slightly preferred based on ranks. Hence, fermented diets can modify the meat quality of broilers to meet consumers’ expectations
Improving Students\u27 Conceptual Knowledge in Online Distance Learning through the Use of Micro-Lectures: A Photosynthesis Example
No full textThe shift to online distance learning due to the COVID-19 pandemic presented a challenge to develop instructional materials that could compensate for the limitations of the prevailing learning modality. Micro-lectures are short instructor-made videos that are meant to deliver lessons in ways that do not overwhelm the learners\u27 working memory in understanding conceptually challenging topics such as photosynthesis. This action research used a Quasi-experimental mixed-method approach through micro-lectures in teaching photosynthesis to an intact group of 60 grade 12 STEM students. The instruments and methods used were pre-test and post-test, survey forms, journal entries, and focus group discussions. The results showed that watching micro-lectures positively affected students\u27 test performance and knowledge gain in the different concepts in photosynthesis. Students view micro-lectures as an effective learning material appropriate for online learning due to their ability to declutter and segment the lessons, enhance engagement levels, provide a sense of teacher presence, and encourage flexible learning
Response of Mungbean (Vigna radiata (L.) Wilczek) to the Combined Application of Carabao Manure and Inorganic Phosphorus in Calcareous Soil
No full textProper fertilization in calcareous soil is necessary to enhance higher crop productivity. This was evaluated through a study that aimed to determine the outcome of the blended application of carabao dung and synthetic phosphorus on the response of mungbean in calcareous soil. To evaluate the correct amount of the blended application of aforesaid materials for effective growth and high seed yield of mungbean grown in calcareous soil. The experiment adopted six treatments such as T0 = No fertilizer application (control), T1 = 30-30-30 kg ha-1 N, P2O5, K2O, T2 = 2.5 t ha-1 carabao manure, T3 = 2.5 t ha-1 carabao manure + 10 kg ha-1 P2O5, T4 = 2.5 t ha-1 carabao manure + 20 kg ha-1 P2O5, and T5 = 2.5 t ha-1 carabao manure + 30 kg ha-1 P2O5. This was laid out in a Complete Randomized Design (CRD) with three replications. Soil analysis revealed that phosphorus application with carabao dung promoted the accumulation of soil organic phosphorus. Statistical analysis showed significant effects (p ≥ 0.01 & p ≥ 0.05) was achieved in all parameters gathered except on the period from sowing to heading and maturity, the production of seeds pod-1, root: shoot ratio, and harvest index. The blended application of carabao dung (2.5 t ha-1) and inert phosphorus regardless of dosage produced a remarkably higher number of pods plant-1 (6.13 – 11.53 pods±0.0000) and higher seed yield (0.70 to 1.40 g plant-1±0.0001) than unfertilized control. The combined application of carabao dung (2.5 t ha-1) and synthetic phosphorus (30 kg ha-1) is an appropriate fertilization strategy for mungbean production in calcareous soil to affect higher productivity
PERFORMANCE OF PROMISING PEANUT (Arachis hypogaea L.) GENOTYPES GROWN IN DRY AND WET SEASON CROPPING
No full textThe development of promising genotypes is a continuing activity by the breeders to give the farmers more choices of varieties to plant. This study aimed to evaluate, determine, and select promising peanut genotypes to be recommended to NSIC as new peanut varieties. There are 10 treatments, including the 3 check varieties, used in this study: T1-JONES, T2- ILOCOS RED, T3- LG Pn 06-36-2, T4- LG Pn 08-4a-2, T5-LG Pn 06-3-4-3a, T6-CVRC Pn 2011-002, T7- CVRC Pn 2011-001, T8-NSIC Pn19, T9- NSIC Pn14, T10- NSIC Pn18. The experiment was arranged in a Randomized Complete Block Design (RCBD) having the 10 treatments replicated 3 times. Results showed that genotypes LG Pn 06-3-4-3a (T5), CVRC Pn 2011- 002 (T6), and CVRC Pn 2011-001 (T7) matured the earliest at 82-90 days comparable to check variety NSIC Pn14. Moreover, LG Pn 06-36-2 (T3), LG Pn 08-4a-2 (T4), LG Pn 06-3-4-3a (T5), CVRC Pn 2011- 002 (T6) attained the shortest plant height at 84-94 cm, comparable to the 2 check varieties NSIC Pn14 and NSIC Pn18. Genotypes planted during dry season produced a significantly higher weight of pods at an average of 2,862 kgha-1 and average total seed yield of 1,796 kgha-1 than wet season cropping at 2,361 kgha-1 mean pod yield and 1,523 kg ha-1 seed yield. Moreover, all peanut genotypes are resistant to moderately resistant to insect pests and diseases. Hence, it is recommended to plant peanuts during dry season cropping as it provides a higher grain yield than wet season cropping under Leyte conditions
Physicochemical Properties and Sensory Attributes of Sweetcorn (Zea Mays L. var. Macho F1) to Combined Application of Organic and Inorganic Fertilizers
No full textFertilizer application does not only influence the growth and yield of sweetcorn but also its physicochemical and sensory attributes. This study was conducted to determine the effects of the combined application of organic and inorganic fertilizers on the total soluble solids (TSS), titratable acidity (TA), pH and sugar contents of freshly harvested sweetcorn, and on the sensory qualities of newly cooked and five (5) day stored sweetcorn. The treatments were designated as follows: T0- Control (without fertilizer applied), T1 - Inorganic fertilizer at 90-60-60 kg ha-1 N, P2O5, K2O, T2- 5,000 kg ha-1 of vermicompost + 45-30-30 kg ha-1 N, P2O5, K2O, T3- 5,000 kg ha-1 of poultry manure + 45-30-30 kg ha-1 N, P2O5, K2O, T4- 5,000 kg ha-1 of cow manure + 45-30-30 kg ha-1 N, P2O5, K2O, T5- 5, 000 kg ha-1 of goat manure + 45-30-30 kg ha-1 N, P2O5, K2O, T6 – 5,000 kg ha-1 of mudpress + 45-30-30 kg ha-1 N, P2O5, K2O, T7 - Foliar spray (Fermented Golden Snail applied five times at 150ml/16liters of water) + 45-30-30 kg ha-1 N, P2O5, K2O. These were laid out in RCBD with three replications. Results showed that the highest pH values and sugar contents were detected from plants applied with 5,000 kg ha-1 regardless of organic fertilizer and half of the recommended rate of inorganic fertilizers. Likewise, sweetcorn stored for five days in an ambient condition maintains its color, taste, aroma, and texture when applied with organic and inorganic fertilizer regardless of the sources of organic materials. It is advisable not to dehusk the sweetcorn during harvest to preserve its marketing potential, especially when it is to be stored. Likewise, only the sweetness/taste of sweetcorn was reduced after five days of storage but still acceptable by the consumers` preference. These results suggested that fertilizer, either pure inorganic or in combination with organic, can significantly increase the yield and also influence its sweetness
Effects of Vermicompost Amelioration on the Soil Properties, Yield, and Profitability of Mungbean (Vigna radiata L.)
No full textVermicompost amelioration is essential to the development of any crop. Mungbean does not need more nutrients, especially Nitrogen, because it can produce N through microbial nitrification. This study aimed to determine the effects on the soil properties, appropriate rates, and the profitability of vermicompost amelioration on mungbean production. The treatments were as follows; T1 - no vermicompost (control); T2 - 1 t ha-1 vermicompost; T3- 2 t ha-1 vermicompost; T4 - 3 t ha-1 vermicompost; T5 - 4 t ha-1 vermicompost and T6-30-30-30 kg ha-1 N, P205, K20 as the positive control. The study was laid in RCB Design with three (3) replications. The results revealed that the application of 4 tha-1 of vermicompost significantly increased the number of days from planting to flowering but high in LAI. Likewise, the weight (g) of 1,000 seeds and the total grain yield (tha-1) were also increased. The heaviest weight of 1,000 seeds was obtained with 4 t ha-1 of vermicompost and 30-30-30 kg ha-1 N, P205, K2O resulted in obtaining the highest grain yield. Application vermicompost 4 t ha-1 vermicompost obtained a higher gross margin of PhP28,300.00 among the vermicompost applied plants comparable to the positive inorganic control plants of PhP30,410.00. Therefore, it is recommended that the farmers use an organic fertilizer at 4 tha-1 of vermicompost for legume production to sustain the soil\u27s fertility and productivity
Problem-Solving Skills of Indigenous People Students Under Inclusive Classroom: A Sex Disparity
No full textDrawing solutions to mathematics problems through converting abstract to fundamental and concrete concepts has also been a challenge for learners. Unquestionably true for Indigenous People (IP) students, especially those in mainstream education. The study focused on determining the problem-solving skill level of IP learners under an inclusive classroom setting. Specifically, it aimed to describe and compare the male and female Mangyan students’ non- routine problem-solving skill levels, focusing on strategic and mathematical knowledge and procedural understanding. This study utilized a quantitative research method employing descriptive design, specifically descriptive-comparative analysis. A total of 60 male and female indigenous students were the study respondents selected thru a stratified random sampling technique. The proponent utilized the adjusted scale of the Illinois Rubric for Mathematics (IRM) to gauge and describe the respondents’ skills in problem-solving. The results revealed that when solving non-routine problems, male IP students are better than females in analyzing and applying appropriate mathematical concepts and strategies but have the same procedural understanding. These indicate male IP students\u27 higher exposure to real-life problems and active participation during class discussions and practice drills. Moreover, results showed those female IP students are timid and intimidated by their non -IP classmates, depriving them of enough exposure to practice problem-solving during practice drills. That is why, when teaching mathematics to IP students, especially problem-solving, teachers should give them relevant knowledge rooted from previous experiences so that they can effectively relate it when solving non-routine problems
Design of a Concentrated Solar Power System Using Computational Fluid Dynamics
No full textConcentrated solar power (CSP) is an alternative approach to harnessing the sun\u27s power to generate renewable energy. As the requirement for the generation of energy grows, the demand for concentrated solar power also increases. Recently, efforts in using CSP technology to generate renewable energy have been adopted globally, with a 6.45 GW capacity installed. With plans of the Philippines to further strengthen the country\u27s energy production and enhance the production of renewable energy in Mindanao, this study proposes to design a CSP specifically for Davao City using a computational fluid dynamics approach. The parabolic dish and a receiver can accommodate a concentrator dish of 10 meters in aperture diameter for installation in Davao City. The design scale-up of the concentrator is then assessed with its efficiency using ANSYS Fluent. In addition, SolTrace and the fluent discrete ordinates radiation model can predict the potential thermal energy extracted from solar radiation. The results show the heat flux pattern in the CSP receiver entrance
The Simulation of Water Level Using Delft3D Hydrodynamic Model to analyze the case of coastal Inundation in Pontianak
No full textSeveral Indonesian coastal areas are prone to tidal flooding, one of which is Pontianak. High tides can trigger floods due to astronomical and meteorological factors. This study discusses the Delft3D hydrodynamics model’s performance in alluding to sea level and wave height in 4 cases of tidal flood events. Final Data (FNL) Global Operational Analysis from NOAA and tidal component data from oceananomatics are used to the Delft3D model. The model output consists of sea level is verified using tide gauge observation data from BIG. This is then used to analyze sea level to 4 flood events with the accumulated rainfall data from GSMaP, wind, pressure from ECMWF, and rainfall observations to describe the hydro-meteorological conditions. Based on four sea-level simulation cases, the Delft3D hydrodynamic model can perfectly reproduce the sea-level rise pattern. This can be seen from the correlation value of 0.93 - 0.96. Even though the simulated seawater level\u27s value has a high error, it was significantly resolved after the datum correction (with a decrease in error of ±7-11 cm). Generally, the most dominant hydro-meteorological conditions affecting the level of flood events are waves and the direction (45°-90° towards the Pontianak Coast) and speed (4-16 knots) of the wind.
In some cases, heavy rain can exacerbate tidal flooding conditions if it coincides with high sea-level conditions. It can obstruct the river\u27s flow into the sea and cause water to overflow on land. This research can be used to consider making early warnings of tidal flooding in coastal areas, especially Pontianak. In addition, it is better to use forecast data (GFS) to make predictions and early warnings of tidal flooding
