This study successfully employed lean manufacturing techniques in conjunction with the DMAIC methodology to enhance the efficiency of a sweet manufacturing production line. By using key performance indicators (KPIs) and value stream mapping, we were able to quantify the improvements achieved. A notable 36% increase in Overall Equipment Effectiveness (OEE) was realized, driven by a 19.4% improvement in performance and a 17.58% increase in quality. While availability experienced a minor decline, the overall gains in performance and quality outweighed this effect. Value stream mapping revealed a significant reduction in rework from 388 kg to 273 kg per production shift, representing a substantial 30% decrease. This reduction directly contributed to a 18.8% increase in production yield, from 612 kg to 727 kg. These improvements were facilitated by the implementation of a Poka-Yoke device and targeted bottleneck analysis. The achievement of the present work encourages to extend the implementation of lean and DMAIC combined methodology to other production lines of the company.

The price of conventional sources of energy such as corn and wheat is high due to insufficient supply and tough competition between humans and animals. This study was done to determine the digestibility of various carbohydrate sources in the diet of native chicken (Gallus gallus domesticus) with regard to dry matter content, apparent metabolizable energy and crude protein. The study result would help poultry raisers to determine alternative, inexpensive energy sources of feed that are available in the local community. There were six dietary treatments used in this study namely: t0-commercial feeds (CF), t1-peeled cassava (PC), t2- peeled sweetpotato (PSP), t3- unpeeled cassava (UC), t4-unpeeled sweetpotato (USP) and t5-grated coconut (GC). The treatments were arranged in Complete Randomized Design (CRD) with four replicates. Native chickens undergone a 10-day digestibility trial. During the digestibility trial, homogenous feces from test diets were collected, weighed and dried as well as the endogenous feces which were collected after no feeding period. Feed sample and collected feces from each treatment were subjected to chemical analysis. The result of this study revealed that PC got the highest percent dry matter digestibility followed by GC. On the other hand, CF statistically got the lowest %dry matter digestibility (DMD) among other treatments. In terms of crude protein digestibility (CPD), PC diet obtained the highest crude protein digestibility while GC obtained the lowest percentage. When it comes to Apparent Metabolizable Energy (AME), native chicken fed with GC diets attained the highest digestibility which is significantly higher than commercial feeds and other diets. The results on the digestibility percentage of dry matter, crude protein and apparent metabolizable energy is determined through the One-way Analysis of Variance (ANOVA). Peeled cassava and grated coconut can be used as energy source of feed for native chicken.

Conflict is a fundamental part of life, emerging in many different contexts. As tertiary institutions resumed in-person classes following the pandemic’s shift to online learning, student nurses like other students encountered numerous challenges and had to make essential adjustments. This quantitative-descriptive study aimed to identify the conflicts encountered by student nurses as they transitioned from online to face-toface learning and describe the conflict management styles they employ in response. A total of 144 respondents answered a researcher-made survey questionnaire to collect necessary data, which were then analyzed using frequency count, percentage distribution, weighted mean score, and standard deviation. Findings indicated that mostly experienced conflicts were intrapersonal; moreover, collaborative and compromising styles were prominent as their conflict management styles. It can be concluded that the respondents mainly involve internal struggles as their conflicts during the transition between learning modalities, highlighting the need for interventions and training programs, which could also enhance their application of other conflict management styles. Additionally, empirical recommendations are provided for educational institutions, relevant stakeholders, and future researchers to enhance the student body’s general well-being and academic success concerning understanding and managing conflicts.

This study aimed to determine the principals’ technology leadership and its relation to the teachers’ technology integration into classroom instruction. Descriptive correlational research was employed where data was obtained using the researcher’s modified survey questionnaire intended to test the level of principals’ technology leadership and the level of teachers’ technology integration into classroom instruction. Mean and standard deviation, t-test, ANOVA, and Pearson’s correlation coefficient were the statistical tools used in the study. Findings revealed that the school principals’ technology leadership of being a visionary leader was high and in almost all of the constructs except on incorporating the school ICT plan with the strategic plans; motivating teacher(s) who needs ICT training to participate as part of their professional development; and recognizing and supporting faculty and staff with exemplary skills in the use of ICT which was very high. When grouped according to sex and age, principals’ technology leadership was high. On the other hand, the teachers’ technology integration was high but varies from low to very high when indicators of integration were considered individually. When grouped according to sex and age, teachers’ technology integration was high. There is no significant difference in the level of technology integration between male and female teachers. However, there is significant difference in the level of technology integration between younger and older teachers. This study concluded that there is no significant correlation between school principals’ technology leadership and teachers’ technology integration to classroom instruction.

Electric power is impossible to imagine in the world. Wires are typically used to transmit power. Envision a future in which wireless power transfer is probable: Mobile phones, household robots, digital audio players (DAPs), laptop computers, and bearable electronics can charge themselves, freeing us from the need to be joint to a power source by a wire. A wireless mobile charging system using the electromagnetic field is intended to clarify its concept by elucidating it. Users can charge their mobile phones wirelessly in this system without the need to plug in the mobile adapter. A charging pad demonstrates the process of charging a mobile phone, requiring users only to place their adapter circuit on it. The transmitting and receiving parts of this system are designed and built as two distinct entities, each utilizing a coupling electromagnetic field. The oscillation circuit converts DC energy into AC energy, which in turn induces a magnetic field by passing through a frequency. This causes the receiver coil to be induced with an alternating current. The magnetic field coupling between the transmitting coil and the receiving coil can be calculated using Ampere’s law, Biot-Savart’s law, and Faraday’s law. In this paper, The ability of the wireless mobile charger is calculated by varying the space between the coils in a system that utilizes an electromagnetic field for charging wirelessly.

This research paper investigates the effectiveness of gamification as a pedagogical strategy for enhancing cognitive skills development among students in higher education, with a particular focus on learners specializing in Electronics and Sensors. In recent years, gamification has become a promising strategy to engage students and promote active learning experiences. However, its impact on cognitive skill development, especially in specialized academic domains, remains relatively underexplored. Through a case study methodology, this research assesses the influence of gamified learning interventions on students’ cognitive abilities, encompassing skills like problem-solving, critical thinking, and decision-making. Data was collected through pre- and post-intervention assessments, student surveys, and qualitative feedback sessions. Results indicate significant improvements in cognitive skills among participants exposed to gamified learning experiences compared to those in traditional instructional settings. The findings suggest that gamification holds promise as a viable educational tool for fostering cognitive skill development in higher education contexts, particularly within specialized fields such as Electronics and Sensors. This study adds to the expanding body of research on gamification in education and provides valuable insights into its potential to enhance learning outcomes in technical disciplines. Future research directions and implications for practice are discussed to further leverage the benefits of gamification approaches in higher education settings.

This study aimed to identify the learning gaps in Filipino sa Piling Larangan (Teknikal-Bokasyunal) during the first quarter of the 2022-2023 academic year. A quasi-experimental study using quantitative method with a design involving assessments before and after were utilized. The research was carried out with 33 TVL 12th Grade learners in the first quarter of the school year 2022-2023 at St. Paul University Surigao. The researcher administered an authenticated assessment for the preliminary and concluding evaluation, finding the disparities in learning in Filipino sa Piling Larangan (Teknikal-Bokasyunal). Significant improvement was observed in five competencies that were initially least mastered. Nevertheless, even with the interventions applied, the resulting mastery level was only partial. Regarding preliminary evaluation performance, most students scored in the fair range. After the interventions, most students achieved a satisfactory level in the concluding evaluation. Additionally, a notable distinction existed on the preliminary and concluding evaluation scores following the intervention. It is suggested that Filipino teachers at St. Paul University Surigao review the instructional areas that need further enhancement to close the ongoing learning gaps and attain full mastery, notwithstanding the implemented interventions.

In order to assess the degree of sustainable leadership components—such as creating a vision and setting direction, getting to know and support peers, overseeing the teaching and learning program, and restructuring the way the 32 public schools district supervisors (PSDS) in the Division of Negros Occidental are organized—this study used a descriptive research design. The majority of the participants were 47 years old and below and mostly were female with master’s degree holders, also were 14 years and below as PSDS almost were married, and with low monthly income. The profile of the participants implies that the variables of age, gender, civil status, and monthly income are not factors or characteristics to influence the sustainable leadership of public schools district supervisors. Therefore, these factors have no bearing on the public school district supervisors’ dedication to carrying out their roles. With the exception of high-level responses on the indicators, where PSDS made sure that appropriate support, like professional development, teaching materials, and planning time, was provided when they were classified according to age, sex, highest educational attainment, length of service, civil status, and monthly income, there was a very high level of building the vision and setting direction, redesigning the organization, understanding, and developing peers in this context. In order to improve the program even further, we close with a prediction regarding the future directions of sustainable leadership research.

This research intends to assess the level of implementation, performance, and compliance in a subset of barangays, as well as awareness of the Katarungang Pambarangay (KP) system in some barangays of Bacnotan, La Union, Philippines. Of the survey conducted, a total of 6,005 respondents participated, in which the respondents include members of the Lupong Tagapamayapa, Pangkat Tagapagkasundo, and Sangguniang Barangay. From the determination of the sample size, the Slovin method was applied using a 5% marginal error. Results showed that all the barangays have highly implemented the KP system, with Barangay Ortega achieving an ‘excellent’ implementation score of 3.99. The result thus indicated good performance of the system in acceptance around 3.50, an indicator that the community education and conflict resolution were effective. The subsequence of the KP processes were also graded, especially in matters concerning the processing of complaints, sending out summonses, conciliation, and support of unresolved matters in court. Lower compliance with physical and infrastructure difficulties, however, was noted in Barangay Arosip. The success of the KP system between the authorities and people of the community was attributed to the high degree of knowledge about the system. On the other hand, the level of knowledge was found to be lower in Barangay Arosip, most likely because of the cultural setting that characterizes this barangay and its tendency to rely fully upon the traditional mechanisms in place to solve conflicts. In conclusion, the KP system of Bacnotan, La Union, is a system required in the promotion of access to local justice, law, and order. Even though it is very effective, it would be to make some improvements for its application in the other localities. It will ensure the system that remains viable to improve the community’s education programs and institutionalize the use of traditional conflict resolution mechanisms in the formal KP structures.

Methyl orange (p-Me2NC6H4N=NC6H4SO3Na; MO) is one of commonly used azo dyes known as an acid-base indicator, along with phenolphthalein. The chemical structural changes of MO with respect to its acid-base equilibrium in aqueous solutions have been learnt in chemical education. The reaction equations vary among analytical chemistry textbooks. Thus, details on the structures of MO are overviewed from historical perspectives for teaching materials in chemistry. Since protonation of MO potentially occurs not only at the azo group (–N=N–) but also at the dimethylamino group (Me2N–), two different chemical species can be considered; i.e., azonium (–N=NH+–) and ammonium (Me2NH+–). In fact, these tautomers of the two protonated MO species exist, and their equilibrium constants have been reported previously. However, ammonium species has not been presented as protonated MO in most textbooks. Misunderstandingly, another confusion concerning the ‘resonance’ between ammonium and quinonediiminium (p-Me2N+=C6H4=N–NHC6H4SO3–) of MO is also presented; exactly, there should be among azonium and quiononediiminium. In order to avoid misconceptions about the chemical structures of MO, these cases should be introduced to chemical educators and learners.
