Multiple-Criteria Decision Analysis for Effect of Shoot Growth at Difference Combination Nutrient Fertiliser NPK for Harumanis Mango

Erdy Sulino Mohd Muslim Tan — 2024-04-01

It is vital to have the correct fertiliser arrangement for effective tree development, fruit yield, and essential fruit quality. The amount of fertiliser suggested with adequate nutrition will be maintained in the soil to supply the needs of the trees as they grow throughout the various growth stages. This study evaluated the effect of different combinations of Nitrogen(N), Phosphorus(P), and Potassium(K) on the vegetative flush physiology of Harumanis mango (Mangifera Indica. L). Single and combinations of N (511g), P(511g), and K(255g) fertilisers were used, which were N, P, NP, and NPK throughout May 2021. The results revealed that the minimum number of mature green leaves and a higher number of healthy panicles were observed in the NPK-treated plants. Moreover, NPK treatment showed the lowest malformation intensity percentage compared to other fertiliser treatments. The data were analysed to obtain the best regrowth pattern of shoots using Multiple-Criteria Decision Analysis (MCDA) techniques. The results on the pattern of regrowth after pruning when federalised with NPK fertiliser showed that the maximum percentage of total vegetative flush was 87.5% and the remaining 12.5% did not reach a satisfactory level according to the MCDA analysis.

Enhancing Vegetable Price Forecasting Accuracy: A Hybrid SARIMA- DWT-GANN Approach

Kar Yan Choong — 2024-04-01

In the context of Malaysia's agricultural sector, the development of a robust vegetable price forecasting model holds paramount importance. The pricing dynamics of vegetables can significantly affect various stakeholders, including farmers, distributors, and consumers. The agricultural sector in Malaysia encounters persistent challenges such as supply-demand imbalances, seasonal variations, and market uncertainties, which can lead to income disparities for farmers and disruption in supply chains. Addressing these issues requires accurate and timely predictions of vegetable prices to enhance planning, resource allocation, and decision-making. This study introduces an innovative SARIMA-DWT-GANN hybrid model for vegetable price forecasting. By fusing the strengths of traditional time series modeling with the capabilities of neural networks, the proposed model offers a comprehensive solution to capture both linear and non-linear price patterns. The results demonstrate the superiority of the SARIMA-DWT-GANN model over the individual SARIMA model, as evident from correlation coefficients that closely approach unity and p-values confirming statistical significance. The model's ability to predict price changes has significant implications for making informed decisions throughout the agricultural supply chain. This research provides a robust forecasting tool that not only enhances market efficiency and profitability but also offers a promising solution to address the challenges in Malaysia's agricultural sector.

Investigating the Effectiveness of Maximum Power Point Tracking (MPPT) with Perturb and Observe (P&O) Algorithm in Solar Power Battery Charging System

Mohd Nadzim Mat Yusoof — 2024-04-01

Solar energy has emerged as one of the most promising and crucial renewable energy sources in our efforts to reduce reliance on fossil fuels and mitigate their adverse impact on the environment. One of the primary applications of solar energy is in the solar power battery charging system. This system harnesses solar energy emitted by the sun through solar panels to charge batteries used as energy storage. At the heart of the solar power battery charging system lies the technology of Maximum Power Point Tracking (MPPT). MPPT is a method used to achieve maximum efficiency from solar panels by adjusting their voltage and current to ensure they constantly operate at their maximum power point, irrespective of varying light conditions. In this article, the solar power battery charging system with the use of the MPPT method employing the Perturb and Observe (P&O) algorithm will be explored. The proposed of modeling the solar battery charging system with the implementation of a DC-DC buck converter and lead-acid battery incorporated with P&O algorithm will be elaborated through MATLAB/Simulink simulation software. Additionally, the performance analysis of the system will be investigated by considering the state of charge (SOC), power (W), current (A), and voltage (V) variables. The simulation results indicate the effectiveness of the proposed P&O algorithm in maintaining the panel’s operating maximum power in multi-stage charging system.

Norliza Hamir Basah — 2024-04-01

The purpose of this study is to examine the influence of relationship quality between Malaysia SMEs exporter and their intermediaries. This paper draws insights from three integrating theories such as social capital theory (SCT), internationalization process (IP) theory and relational exchange theory (RET) to examine the synergistic outcome of several constructs on export performance. The model is tested using Structural Equation Modeling (SEM) via Smart PLS on a sample of SME exporters in Malaysia. The findings reveal that all hypotheses are supported. The research highlights that cultural similarity is a catalyst in the internationalization process and show the mechanism of how it (cultural similarity) can influence effective communication and lead to knowledge sharing process thus impetus trust which finally reflect the performance outcomes. Results also confirm that trust serves as a mediator between cultural similarity and export performance. The findings extended the application of the underpinning theories and their tenets in explaining the Malaysian SMEs’ export performance use foreign intermediaries.
