Abstract

In today’s digital era, integrating technology into education has become essential for enhancing learning experiences and outcomes. This study adopted a descriptive survey design to investigate the use of technology integration among Home Economics students in Food and Nutrition programs in Colleges of Education in Anambra State. A sample of 55 students was selected through proportionate stratified random sampling. Data were collected using a validated questionnaire (TIFNEQ), with Cronbach Alpha coefficients of 0.86 (awareness), 0.77 (extent of use), and 0.81 (perceived benefits). The researcher personally administered the instrument, achieving a 100% response rate. Data analysis involved descriptive statistics, ANOVA, Duncan post-hoc test, and Pearson correlation, using SPSS version 25, with significance set at the 0.05 level. The study involved 55 Home Economics students, of which (12.7%) were below 20 years, (36.4%) between 20–25 years, (27.3%) aged 26–30, and (23.6%) above 30. By level of study, (16.4%) were in Year I, (27.3%) in Year II, (38.2%) in Year III, and (18.2%) in Year IV. Females represented a majority (89.1%) compared to males (10.9%). In terms of technology availability, the overall mean scores indicated moderate access to tools (mean = 2.96, SD = 1.19), with Year I students reporting the highest availability (mean = 2.73). A significant difference was found across levels of study in technology availability (F (3,51) = 4.03, p = .012). A strong positive correlation existed between availability and extent of use (r = .860, p < .001). Similarly, extent of technology use differed significantly across levels (F (3,51) = 3.33, p = .027), with Year I students again reporting the highest use (mean = 3.11). Perceived benefits of technology also varied significantly (F (3,51) = 3.94, p = .013). A very strong correlation was found between extent of use and perceived benefits (r = .964, p < .001), confirming a meaningful link between practice and value perception. The study concludes that while some digital tools are in use, technology integration is not uniformly implemented, and its potential is underutilized. The study recommends improved provision and equitable access to digital resources to enhance learning in Home Economics

Abstract

This study examined the teaching of English Language through Artificial intelligence in a globalised world focusing on how AI assisted language learning and teaching across the globe. These areas such as vocabulary, syntax and lexis have been greatly influenced by AI, hence making the learning and teaching of English Language accessible, understandable and simpler. Even though, the English Language has gained wider acceptance and used in virtually all the sectors, yet second language learners still have problems navigating in the areas of forming correct sentences, right spellings and correct usage of words. The study relied on systemic functional linguistic theory by M.A.K Halliday which stated that language is viewed as a source for making not only one meaning at a time but several strands of meaning simultaneously. It is equally excellent in understanding how English is used in context focusing on the function of language to create meaning in social situations. The study would also rely on technological mediation theory by Verbeek which asserted that AI is not just a neutral tool but as an agent that shapes linguistic practices and identities. A descriptive qualitative design was used to examine grammar conformity, lexical choices and syntactic structures. Data were collected using structured questionnaires. Findings from the study revealed that wrong syntactic structure, poor lexical choices and inadequate grammar conformity were the problems encountered in the teaching and learning of English Language. The study concluded that teaching and learning of English language through artificial intelligence is crucial because it makes the learning of English easier and simpler for language learners. The following recommendations among others were made which includes that teachers should master the use of proper lexical words, adequate grammar conformity and syntactic structure in to enhance English Language teaching and learning. The study contributed to existing knowledge by providing rich empirical data on the relationship between English Language and artificial intelligence for efficient language teaching and learning.

Abstract

The study examined the difficulties students encountered in pronouncing diphthongs. Specifically, the study highlighted some areas that posed problems for students in articulating diphthong sounds. The study was anchored in language acquisition theory, which posited that learners have acquired a first language and that their L1 might hamper the articulation of sounds, and in error analysis theory, which stated that a learner’s errors reflect their learning process. Here, the errors an L2 learner makes are traceable to either intra-lingual or developmental in nature or inter–lingual (transfer). A descriptive research design was adopted to describe the areas students find difficult when pronouncing diphthongs. Data were collected through structured questionnaires. Data were equally analyzed using mean scores. The study's findings revealed that ignoring glides in pronunciation and overemphasizing the first vowel were among the problematic areas that students couldn’t articulate properly. The study concluded that students should be exposed to continuous drilling to improve their pronunciation skills. This is because a second language learner has not gained veritable knowledge of how these diphthongs are pronounced. It was recommended, amongst others, that teachers attend workshops on the training prevalent in these diphthongs and possibly teach the students more effectively.

Abstract

The utilization of solar energy is an important solution in meeting renewable energy needs, especially in Indonesia which has high irradiation potential. However, photovoltaic (PV) systems face challenges in the form of irradiation fluctuations and partial shading effects that reduce efficiency. To overcome this, a reliable Maximum Power Point Tracking (MPPT) algorithm is needed. This study analyzes the performance of the Queen Honeybee Migration (QHBM) algorithm in tracking the maximum power point (MPP) under uncertain irradiation conditions in the Tulungagung region, using a Monte Carlo simulation approach. Simulations were conducted using MATLAB in two scenarios: standard conditions (1000 W/m²) and fluctuating conditions based on historical data. Results show that the QHBM achieves 99.98% efficiency with the fastest convergence time (5 iterations) under STC conditions, as well as an average efficiency of 98.99% (normal) and 97.86% (abnormal) under fluctuating conditions. In addition, the system successfully charged the battery, with SOC increasing by 0.038% (optimal) and 0.026% (volatile). The QHBM algorithm is proven to be adaptive to irradiation dynamics and superior to GWO, PSO, and P&O, making it a potentially effective solution for PV systems operating under changing irradiation conditions throughout the day

Abstract

This research aims to optimize a hybrid photovoltaic (PV) energy system for a coffee shop business in Malang City by incorporating economic, environmental, and social dimensions. The optimization process employs the Queen Honeybee Migration (QHBM) algorithm, a multi-objective heuristic approach. Key performance indicators include Cost of Energy (COE), Carbon Emissions, Renewable Fraction (RF), and Community Acceptance, which is evaluated using the Technology Acceptance Model (TAM) through a structured questionnaire. The system is designed to meet a daily energy demand of 28.8 kWh, under an average solar irradiation of 3.86 kWh/m²/day. Simulation and optimization were conducted using Python-based programming. The results demonstrate that the optimal configuration consists of 20 solar panels (550 Wp) and 10 battery units (200 Ah), achieving a COE of IDR 320.04/kWh and an RF of 99.87%. Compared to conventional grid electricity, the proposed system offers significant cost savings and emission reductions. Furthermore, the TAM-based survey yielded an average acceptance score of 3.72, indicating a favorable public perception of hybrid PV system adoption in small business contexts.

Abstract

Solar power system is a renewable energy generator which is currently experiencing quite rapid development. One of the most important components of PLTS is the inverter. Inverter is a component that is used to convert direct voltage (DC) into alternating voltage (AC). However, in its implementation, the AC wave generated by the inverter is not yet a pure sinusoidal waveform. This is because there is harmonic distortion that exceeds the permitted standards. Based on IEEE STD 519-2014, the permitted Total Harmonic Distortion (THD) is not to exceed 5%. This study aims to analyze the reduction of harmonic distortion on Multilevel Inverters by using SPWM modulation and passive filter optimization. Harmonic distortion is reduced to not exceed the permissible standard, namely 5%. This study uses the Cascaded H-Bridges Multilevel Inverter (CHB-MLI) topology using PODPWM as the modulation technique. After that, the LCL passive filter is designed using the PSO Algorithm to optimize the parameters that make up the LCL filter. The results showed that the PSO Algorithm was able to optimize the passive LCL filter design used to reduce harmonic distortion in Multilevel Inverters. With parameter values L1, L2, and Cf each of 22.163 mH, 8.888mH, and 7.0984 μF; able to reduce the THD value to 3.06%.

Abstract

Energi listrik merupakan salah satu hal yang menjadi kebutuhan pokok bagi banyak orang. Hal tersebut mengakibatkan tuntutan pelanggan terhadap penyedia listrik semakin tinggi, dari sisi kualitas dan kontinuitas sistem distribusiKeandalan sistem distribusi dapat dinilai dari frekuensi pemadaman listrik, durasi terjadinya pemadaman dan durasi perbaikan kegagalan. Analisis keandalan seperti SAIFI, MAIFI, SAIDI dan CAIDI dapat dilakukan untuk menentukan keandalan sistem. Pada studi penelitian ini, dilakukan analisis keandalan sistem distribusi pada penyulang Glagahwero menggunakan Metode RIA (Reliability Index Assessment) untuk memprediksi kegagalan keandalan komponen dan topologi sistem. Analisis akan dilakukan dengan dua syarat, yaitu penyatuan sempurna dan penyatuan tidak lengkap. Berdasarkan hasil perhitungan dan analisa pada saat sistem dalam kondisi switching sempurna, nilai maksimum diperoleh pada item 2 dengan SAIFI = 4,118157662 kali/tahun dan MAIFI = 0,061772365 kali/tahun, SAIDI = 4.3766 jam/tahun, CAIDI = 1,0768 jam/tahun. Pada kondisi konversi tidak sempurna, nilai tertinggi juga diperoleh dari paragraf 2 dengan SAIFI = 4.1273 kali/tahun dan MAIFI = 0.06177 kali/tahun, SAIDI = 4.4193 jam/tahun, CAIDI = 1 ,0833 jam/tahun. Hal ini dikarenakan jumlah pelanggan yang ada pada section 2 lebih banyak dari pada section lain. Pada hasil perhitungan dan analisa dari data pemadaman diperoleh nilai SAIFI yang sama pada semua kegagalan adalah 2,311 kali/tahun, sedangkan nilai SAIDI tertinggi adalah 0,6145 jam/tahun. Dibandingkan dengan standar PLN, khususnya SPLN 68-2: Tahun 1986 dengan SAIFI 3,2 kali/jam dan SAIFI 21 jam/tahun. Maka, berdasarkan hasil nilai SAIDI pada pasal 2 dapat dinyatakan tidak andal dan tidak memenuhi kriteria PLN. Sedangkan berdasarkan hasil nilai SAIDI pada bagian 1, 3, 4, 5 dan 6, serta hasil nilai CAIDI pada semua bagian, sistem distribusi dapat dinyatakan handal dan sesuai dengan standar PLN.
