**HIGHLIGHTS**

  - Fuzzy Analytic Hierarchy Process (FAHP) has been used to determine ranking factors.

  - The primary data was collected by distributing Google Forms to six experts.

  - This study identifies the most influential factor contributing to students' selection of outstanding students.

**ABSTRACT**

*The best student award is an award that students, particularly those who perform best, look forward to receiving. It recognized students who have achieved success in both academic and extra-curricular activities during their undergraduate years. However, there are other challenges in the student selection decision such as having trouble in selecting the student with what characteristic features should be considered and prioritized. Hence, the management needs to take an initiative to make students more satisfied with the new process and result. This study aims to determine the important factors and sub-factors needed to select the student for the best student award and rank them according to the most important influence level. To achieve the objective, the Fuzzy Analytic Hierarchy Process (FAHP) has been used to determine ranking factors between including Cumulative Grade Point Average (CGPA), soft skills that students possess, discipline, and participation in extra-curricular activities. Each factor comprises three sub-factors. The primary data was collected by distributing questionnaires to six experts, consisting of three (3) academic administrators and three (3) student administrators using google form*. *Discipline, with a normalized weight of 0.363, is the most important factor in students' selection of excellent students. With a normalized weight of 0.485, sub-factor teaching and learning process is the most essential for CGPA. With a normalized weight of 0.445, self-confidence is the most important sub-factor under soft skills. Subfactors free from disciplinary action (normalized weight 0.414) are significant for the factor discipline and giving commitment (normalized weight 0.482) are significant for the factor extra-curricular activities. Based on this outcome, it shows that Fuzzy AHP is a method that can assist experts to decide under complicated situations and precisely rank all factors and sub-factors. High satisfaction among students with selection decisions will most likely lead to their high and extraordinary fighting spirit*

# INTRODUCTION

The best student award is one initiative established to award students who achieve not only in academics but also in developing important soft skills such as leadership, discipline, teamwork, and communication (Ajoi et al., 2021). Being selected as the best student is a significant thing when studying, but in terms of what is assigned to the student is one of the critical things to focus on. The standard approach in evaluating students’ performance at university is merely based on academic achievement only. Nevertheless, in real-life situations, some students have other characteristics to be the best students, such as soft skills, discipline, co-curricular participation, and many more. Evaluating a student achievement usually comprises many components, each of which involves many judgments, many of which are based on inaccurate data (Yadav and Singh, 2011). Therefore, the institution needs to ensure that the selected students are students who meet the main criteria that have been set. They should know the factor or criteria that contribute to the student selection for the best student award. Some students find it difficult to be selected as the best student as they cannot afford to get a 4.0 pointer every semester, making them feel unmotivated. Because of that, other criteria need to be looked at and consider being fairer, which will make students more motivated during their studies.

The AHP is an effective method for addressing complicated selection issues. Any complicated problem may be decomposed into numerous sub-problems using hierarchical levels, with each level reflecting a set of criteria or qualities relevant to each sub-problem (Sun, 2010). Laarhoven and Pedrycz created the FAHP in 1983, according to Othman et al. (2020), which is a technique of analysis that blends fuzzy theory and AHP. In this technique, the fuzzy theory's membership functions, such as fuzzy triangular numbers, are given as paired comparisons of matrices, which shifts expert views from previously definite values in the traditional AHP to fuzzy numbers.

Due to the essential and specialty of the best student award to the students, we need to identify the most influential factor contributing to students' selection of outstanding students. The objective of this study is to determine the important factors (characteristics) needed to select the student for the best student award, determine the important sub-factors (sub-characteristics) needed to select the best student for the best student award and to rank the factors and sub-factors needed to select the best student for the best student award using Fuzzy AHP. Chen et al. (2015) found that the hierarchical structure should be developed based on the selected factors and subfactors. The main framework to evaluate the factors is summarized in a hierarchical structure shown in Figure 1:

# METHODOLOGY

**A survey was performed to assess the important factors influencing students’ selection decisions for the best student award. The questionnaires will be distributed to six experts, consisting of three (3) academic administrators and three (3) student administrators using google form. The questionnaire comprises four (4) factors and twelve (12) sub-factors. The questionnaire has two (2) sections: part A and part B, where each piece** uses the classic Saaty's scale. Part A evaluates the factors, while part B evaluates the sub-factors of this research. Figure 2 shows the FAHP phase process in this study.

**Step 1:** A triangle fuzzy number (TFN) represented by (*l, m, u*) is used to identify a fuzzy set, where *l* is the smallest possible value, *m* is the most promising value, and *u* is the greatest possible value. Othman et al. (2020) found that the triangular fuzzy number correlates significantly to the preferred ratio scale shown in Table 1.

**Step 2:** To achieve the results, substitute the fuzzy triangular scale into the pair-wise comparison matrices for each criterion and sub-criterion. The experts' fuzzy triangular scale for pair-wise comparison matrices is created using the following equation:

**Step 11:** Since all the steps have been calculated, the factors then ranked according to the final weight after normalization. The highest normalized weight is determined as the important factor (characteristic) needed to select the student for the best student award.

**FINDINGS AND DISCUSSIONS**

The relative weight of factors that have been normalized using the FAHP approach is shown in Table 3. From the normalized weight shown in Table 3, Discipline is the key factor that most influences in determining the selection of outstanding students with the highest normalized weight of 0.363. According to the academic rules of diploma and bachelor's degree UiTM, one condition for receiving the vice chancellor's award and the dean's award is that the student has never been convicted of disciplinary action while being a student at UiTM (ICEPS, 2021). Next, the important factor is the soft skill of the student, Cumulative Grade Point Average, and Extra-Curricular Activities with normalized weight 0.333, 0.246 and 0.058, respectively.

**Table 3:** Non-Fuzzy Weight and Normalized Weight of Factor to Determine the Important Factor

| Extra-Curricular Activities    | 0.06                 | 0.058                 |

Table 4 shows the weight of the sub-factor of each factor. Based on the result obtained, the important subfactor for Cumulative Grade Point Average is the teaching and learning process with the normalized weight of 0.485. For soft skills, the self-confidence of students has the highest normalized weight, which is 0.445, and it means that is the most important sub-factor for “Soft Skills”. For the discipline factor, the free-from disciplinary action is more important that needs to be considered with the normalized weight 0.414. Lastly, for the factor extra-curricular activities, commitment has the highest normalized weight, which is 0.482.

Table 5 shows that the discipline of the students is the most influential factor needed in selecting the best student for the best student award, with a normalized weight of 0.363. It means that students are positively always take care of and values ​​their discipline throughout their studies at the university. Discipline refers to the scheme of regulations, penalties, and behavioural tactics suitable to the ruling of university students and the upholding of order in the universities. The next factor that influences the selection of outstanding students is soft skills with a normalized weight of 0.333, followed by Cumulative Grade Point Average with a normalized weight of 0.246, and extra-curricular activities with a normalized weight of 0.058.

**Table 5:** Ranking of the Factors

| **Factor**                     | **Non-Fuzzy Weight** | **Normalized weight** | **Rank** |
| ------------------------------ | -------------------- | --------------------- | -------- |
| Cumulative Grade Point Average | 0.251                | 0.246                 | 3        |
| Soft Skills                    | 0.340                | 0.333                 | 2        |
| Discipline                     | 0.372                | 0.363                 | 1        |
| Extra-Curricular Activities    | 0.060                | 0.058                 | 4        |

After ranking the factors, the next step is to rank the sub-factors that influence the best students’ selection decision from students’ views. From Table 6 the experts indicate that teaching and learning process is the most important to an excellent CGPA with a normalized weight of 0.485 than self-motivation with a normalized weight of 0.276 and attitude of students towards the course with a normalized weight 0.239. That means lecturers should improve their teaching methods to encourage students to actively participate in class. A positive teaching and learning environment could have a significant impact on their CGPA. Next, Table 6 shows that self-confidence under soft skills of students has a higher normalized weight is 0.445 higher than the impact of society and awareness and preference. The experts agree that being self-confident will make students improve their soft skills. Having high self-confidence will make students feel courageous in trying things.

Furthermore, for factor discipline in Table 6, the experts recognize that sub-factor have a free from disciplinary action play an important part than good manners and obey the instruction with normalized weight 0.414, 0.367 and 0.219 respectively. It shows that the expert agrees that having a satisfactory level of discipline allows students to complete more work in less time, because their attention is focused, and they are not wasting time on distractions such as social media because of the disciplined approach to time management for the example. Furthermore, students can finish their work on time, stay involved in their studies, and have more time free to pursue things that are important to them, such as sports, hobbies, youth group, and spending time with friends and family, by managing their time well.

Based on Table 6, giving commitment is particularly important in the involvement of extra-curricular activities than being an excellent organizer and having effective communication with normalized weight 0.482, 0.290 and 0.228, respectively. It shows that the experts prefer students who are fully committed to the responsibilities held as a key sub-factor for extra-curricular activities. Thus, commitment to extra-curricular activities will provide opportunities to demonstrate leadership and character.

Therefore, based on an all ranking of sub-factor, the university needs to take more consideration on the involvement and commitment of students in extra-curricular activities because most of the students are satisfied with the selection decision by the university if they take precedence of student’s commitment. With regards to students obeying the instruction under the discipline factor, the experts recognize it should be the least sub-factor that affects students’ selection for the best student award.

**CONCLUSION AND RECOMMENDATIONS**

This study aims to determine and rank the factors and sub-factors that influence the selection decision of outstanding students. The selected factors used in this research are Cumulative Grade Average Point (CGPA), soft skills that students have, discipline, and extra-curricular activities. The data used were collected from six experts consisting of 3 academic administrators and 3 student administrators based on UiTM Perlis. The FAHP method which combines the fuzzy theory and AHP has been applied and has successfully achieved the objectives of this study, specifically to determine and rank the important factors and sub-factors that influence the selection decision of outstanding students for the best student award. Hence, based on the results using FAHP, this study concludes that the most important factors are the level of student discipline throughout their studies at the university, followed by soft skills that students have factor, CGPA factor, and lastly extra-curricular activities factor. For the sub-factor under discipline, the most important is free from disciplinary action. Furthermore, the important sub-factor for soft skills is self-confident. As for the CGPA, the teaching and learning process is the important sub-factor that needs to be considered while for Extra-Curricular Activities, the most important sub-factor is the students’ commitment.
