Abstract

In the ever-changing landscape of the global economy, the role of the United States Dollar (USD) as the backbone of the international financial system significantly influences market stability and dynamics. The close correlation between fluctuations in the USD exchange rate and internal and external factors demands effective prediction methods to understand and manage associated risks. This study aims to compare the performance of three main prediction methods: Single Exponential Smoothing (SES), Holt's Method, and Holt-Winters Method, in forecasting USD exchange rates. Utilizing historical data from the Central Statistics Agency (BPS) and testing under three training data distribution scenarios (45%, 55%, and 75%), this research provides in-depth findings on the strengths and weaknesses of each prediction method. Performance evaluations include the time required, Mean Absolute Error (MAE), Mean Squared Error (MSE), Mean Absolute Percentage Error (MAPE), R-Squared, and correlation for the implementation of each method. If averaged, the results are as follows for SES, Holt’s, and Holt’s Winter, respectively: SES (1.58; 284.20; 68,768.26; 440.07; 0.03; -2.12; Nan), Holt’s (1.39; 890.23; 426,377.44; 1,043.28; 0.06; -24.28; -0.66), and Holt’s Winter (1.20; 997.45; 513,657.58; 1,168.00; 0.07; -30.62; -1.55). Overall, this indicates that the Holt-Winters Method stands out with significant performance, especially in scenarios with larger training data distributions, with a low R-Squared value (-4.618) and satisfactory correlation (0.417). Holt's Method also shows improved accuracy, while Single Exponential Smoothing (SES) offers time efficiency, albeit with limitations in explaining data variations. In conclusion, this research provides valuable guidance for business stakeholders, investors, and policymakers in selecting prediction methods suitable for their data characteristics and analysis goals, with the potential for a positive impact on business strategies, competitiveness, and risk management amid the uncertainty of USD exchange rate fluctuations.

Abstract

Manusia tak lepas dari aktifitas sehari-hari. Seorang pekerja harus berangkat ke kantor untuk bekerja. Seorang pelajar harus berangkat ke kampus ataupun ke sekolah untuk belajar, dan sebagainya. Terkadang seseorang tersebut berangkat untuk melakukan aktifitas masing-masing menuju tempatnya menggunakan kendaraan yaitu mobil. Harga mobil yang begitu mahal dan hanya dimiliki oleh kalangan tertentu, membuat pemilik cenderung menambahkan sebuah alat yang dapat memberikan tingkat keamanan yang lebih tinggi agar terhindar dari tindak kriminalitas pencurian mobil yaitu dengan menambahkan fingerprint car starter. Pemanfaatan fingerprint car starter digunakan ketika pemilik akan menghidupkan mesin mobil. Fingerprint car starter ini menggunakan metode support vector machine (SVM). SVM adalah salah satu metode jaringan syaraf tiruan pada pengenalan sidik jari. SVM mengimplementasikan prinsip structural risk minimization yang bertujuan untuk meminimalisasi sebuah hubungan dari kesalahan umum. Keuntungan lain menggunakan metode SVM adalah hasil pelatihan dari SVM dapat menyelesaikan solusi yang unik dan optimal. Cara kerja dari sistem ini yaitu meng-input-kan sidik jari ke dalam alat ini. Sebelum sidik jari diproses, sidik jari telah tersimpan ke dalam database. Kemudian sidik jari diklasifikasi ke salah satu database sidik jari yang telah tersimpan. Jika sidik jari tersebut sesuai dengan database sidik jari yang tersimpan, maka mesin mobil akan menyala dan mobil siap untuk digunakan.

Abstract

Problem-solving skills are essential competencies for vocational graduates in aviation education, where professional tasks are characterized by high risk, time pressure, and technological complexity. This study examined the effectiveness of Problem-Based Learning (PBL), Project-Based Learning (PJBL), and a combined PBL–PJBL approach in improving the problem-solving skills of cadets at an Aviation Polytechnic in Surabaya. A quantitative method with a quasi-experimental design was employed. A total of 100 first-year cadets were selected through purposive sampling and assigned to four groups: PBL, PJBL, combined PBL–PJBL, and a control group. Data were collected using a validated and reliable questionnaire administered as pretest and posttest, and analyzed using one-way ANOVA, Tukey’s HSD post hoc test, and N-Gain analysis. The results indicate that all experimental learning models significantly improved cadets’ problem-solving skills compared to the control group. The combined PBL–PJBL model demonstrated the strongest overall effect, yielding the highest statistical improvement and a very large effect size. When examined as single-method implementations, PBL produced higher learning gains than PJBL, indicating greater practical efficiency in developing problem-solving skills. These findings suggest that while PBL alone is an effective and efficient instructional approach, integrating PBL and PJBL provides a more comprehensive learning experience that maximizes problem-solving development in aviation vocational education. The study highlights the importance of aligning instructional strategies with the cognitive and operational demands of aviation training contexts.

Abstract

Globalization increasingly demands graduates who are able to communicate across cultures confidently and appropriately. However, limited evidence explains how culturally diverse students in semi-military vocational settings experience intercultural learning, particularly when language barriers and differing expectations shape their academic and social adjustment. This study explores the motivations, perceived benefits, challenges, and intercultural learning experiences of foreign students enrolled at Surabaya Aviation Polytechnic. Using a qualitative case study approach, data were collected from 18 Timor-Leste students through semi-structured interviews and open-ended questionnaires, and analyzed using deductive–inductive thematic analysis with data triangulation. The conceptual frameworks of intercultural communicative competence (ICC), cultural intelligence (CQ), and self-efficacy in English use informed the construction of interview guides and the interpretation of findings. Results reveal six key motivations for studying abroad, mainly career advancement, institutional reputation, and program practicality. Nevertheless, students experienced a clear gap between expectations and reality. Limited interaction with local peers, regional language accents, and low confidence in using English led to reduced frequency of intercultural encounters, social withdrawal, and stagnation in ICC development. Personal factors such as introversion and language anxiety further constrained participation. The findings suggest that authentic intercultural exposure, confidence-building strategies, and structured cultural preparation are essential to support students’ integration and learning. Practically, institutions should provide mentoring, communication simulations, and media-based cultural orientation to improve students’ readiness, emotional regulation, and self-efficacy. The study contributes to the literature by highlighting how intercultural learning unfolds in a unique vocational aviation context and by proposing practical approaches to enhance students’ intercultural development.

Abstract

Airport signage is a core wayfinding facility that can reduce uncertainty and support passenger movement in complex terminal environments. This study examined the effect of signage quality—operationalized through clarity, placement, and lighting—on passenger satisfaction in the departure area of Terminal 1, Juanda International Airport. A quantitative cross-sectional design was applied to 100 passengers using a 24-item, five-point Likert questionnaire. Twelve items measured signage quality and twelve measured passenger satisfaction. Instrument quality was assessed through item-total validity and Cronbach’s alpha, followed by normality testing, Pearson correlation, and simple linear regression. All items were valid; reliability was high for signage (α = 0.957) and passenger satisfaction (α = 0.936). Signage quality was strongly associated with passenger satisfaction (r = 0.959, 95% CI [0.940, 0.972], p < 0.001), and explained 92.0% of the observed variance (R² = 0.920). Lower-scoring items concerned ease of locating signs, orientation, reduction of confusion, and overall satisfaction with directional clarity. The novelty of the study lies in isolating the physical characteristics of airport signage as a specific service-quality determinant in an Indonesian terminal context rather than treating signage as a minor part of a broad facility index. The findings extend airport service-quality research by linking tangible information infrastructure with passenger satisfaction and provide a practical basis for signage audits, decision-point placement, lighting improvement, and passenger-centered terminal planning. Because both variables were measured through the same cross-sectional questionnaire, the unusually high R² should be interpreted cautiously and verified through multi-airport and multi-method studies.

Abstract

The potential of regional airports as living laboratories for child-friendly educational tourism is often constrained by the readiness of front-line service personnel. This community service initiative aimed to enhance the understanding and capacity of 34 operational staff at Abdulrachman Saleh Airport, Malang, in facilitating aviation educational tourism. Utilizing a Participatory Action Research approach, the program was conducted through socialization, child-friendly interaction simulations, and Focus Group Discussions (FGDs). Data were evaluated using a 4-point scale assessment and qualitative thematic analysis. Quantitative results demonstrated program success, with a total average score of 3.52 (Good category). Attendance achieved the highest score (3.85), while practical simulation scored the lowest (3.47) due to psychological barriers in shifting from a rigid work demeanor to a flexible attitude. In conclusion, the program successfully transformed staff into non-formal educational agents. Program sustainability requires written SOPs to integrate aviation safety protocols with children's tour routes.
