Abstract

This study presents an integrated approach to vehicle vibration pattern analysis and early fault detection using Artificial Neural Network (ANN) modeling to address key maintenance challenges, including unplanned engine downtime and the limitations of conventional time-based preventive maintenance strategies. The research combines empirical vibration measurements obtained from internal combustion engines with a computational ANN model developed to automatically classify engine health conditions. The experimental phase focused on collecting vibration data under three operational states: normal, degrading, and faulty, each exhibiting distinctive vibration characteristics associated with combustion pressure variations and mechanical imbalance.A total of 500 vibration samples were recorded, with 400 used for ANN training and 100 for validation. The proposed feedforward multilayer perceptron (MLP) model achieved a classification accuracy of 94% with a mean squared error of 1.5 × 10⁻⁵. The ANN successfully identified transitional degradation patterns between normal and faulty states, demonstrating its capability for early fault diagnosis and supporting timely maintenance intervention and improved maintenance scheduling. Furthermore, the results reveal a strong correlation between combustion chamber pressure fluctuations and vibration amplitude, confirming that increased pressure irregularities lead to higher vibration energy levels. Overall, the proposed ANN-based vibration monitoring framework provides a non-invasive, cost-effective, and reliable solution for real-time engine condition assessment. By enabling early detection of mechanical degradation and reducing the risk of unexpected failures, the approach contributes to enhanced equipment availability, lower maintenance costs, and the effective implementation of predictive maintenance systems in automotive and industrial applications.

Abstract

As environmental awareness grows, fast fashion brands increasingly adopt sustainability messaging to appeal to eco-conscious consumers. However, such efforts often raise concerns about greenwashing—where environmental claims are exaggerated, vague, or unsubstantiated. This study critically examines Shein’s evoluSHEIN campaign using Stöckl and Molnar’s Eco-Advertising Framework, which integrates linguistic and visual analysis to assess how brands construct eco-friendly narratives. Five official advertisements from 2024 were analyzed using Critical Discourse Analysis and multimodal semiotics. The findings identify five recurring greenwashing strategies: vague eco-lexicon, symbolic eco-imagery, unverified eco-certifications, emotional moral framing, and unsubstantiated absolute claims. Terms like “sustainable” and “eco-safe” are used without definition or evidence, while visuals—such as leafy graphics and green color schemes—reinforce environmental connotations without transparency. Moral slogans like “Join the fight for a greener planet” shift responsibility to consumers, framing ethical purchasing as the solution while masking Shein’s ongoing high-volume, low-cost production model. These strategies construct a cohesive yet largely symbolic environmental message, aligning with broader fast fashion trends where marketing appeal outweighs operational change. The study argues that this multimodal approach to greenwashing risks misleading consumers and eroding trust in legitimate sustainability initiatives. By highlighting the interaction between language and imagery in shaping perceptions of environmental responsibility, this research underscores the need for clearer regulatory standards, credible third-party certifications, and increased consumer media literacy. It contributes to the critical understanding of how greenwashing operates systemically within fast fashion and how ethical branding narratives may conceal unsustainable practices.

Abstract

Dalam perkembangan ilmu pengetahuan dan teknologi saat ini, mobil menjadi transportasi utama dengan manfaat signifikan seperti memudahkan mobilitas dan menghemat waktu. Berdasarkan data GAIKINDO tahun 2023, penjualan mobil di Indonesia mencapai 90.835 unit, naik 15,6% dibanding tahun 2022. Peningkatan ini memicu kebutuhan material untuk komponen mobil, termasuk material isolator panas yang umumnya terbuat dari bahan sintetis seperti ceramic blanket dan glass wool. Namun, material tersebut memiliki kelemahan seperti berat, biaya tinggi, dan risiko kesehatan. Serat ampas tebu dipilih karena sifat mekaniknya yang baik, tidak korosif, ringan, murah, dan ramah lingkungan. Penelitian ini menggunakan metode ekstraksi dengan larutan NaOH 5% dan aquades selama 1 jam, serta fraksi volume serat 20% : 80%, 25% : 75%, dan 30% : 70%. Polipropilena digunakan sebagai matrik untuk mengikat serat ampas tebu. Kombinasi ini diharapkan menghasilkan komposit dengan ketahanan panas dan kekuatan tarik yang optimal. Pembuatan komposit di lakukan dengan menggunakan metode thermal bonding. Penelitian ini menganalisa ketahanan suhu dengan oven pemanas dan sifat mekanik uji tarik menggunakan standar ASTM D 638 tipe 1. Fokus penelitian ini adalah "Pengaruh Penggunaan Komposit Berbahan Serat Ampas Tebu Bermatrik Polipropilena Dengan Metode Thermal Bonding terhadap Kekuatan Tarik."Hasil penelitian menunjukkan bahwa komposisi fraksi volume 25%:75% memberikan kekuatan tarik optimal dengan nilai 21,90 N/mm³ setelah perendaman NaOH 5%.

Abstract

The type of research used in this thesis is qualitative research in which the data are taken from collecting the words, quotations, sentence and narration that stated in Coraline by Neil Gaiman. The primary data are taken from Neil Gaiman’s Coraline in the form of dialogues, sentences, and narration stated by the character about how an ideal family is represented in the novel. Then, the secondary data are taken from books, internet, and another source related to the representation of an ideal family. This research analyzes the ideal family concept in Coraline by Neil Gaiman with the theory of representation by Stuart Hall. The concept of an ideal family is explained by using the constructionist approach and focuses on the discursive formation. The discursive formation is applied to analyze the discourse of an ideal family that is shown in Coraline. The finding of this research shows that the purpose of the main character, Coraline in hoping to have an ideal family in her life is to feel loved by her parents. The representation of an ideal family in Coraline is depicted through the two aspects, those are how they define a family, and the importance of a good parenting.

Abstract

This research aims to analyze how Kathryn Stockett's The Help represents systemic racism and author's critical position towards the racial injustice issue within the novel. This research applies two theories: the representation by Stuart Hall and the theory of systemic racism by Joe. R. Feagin. This research applies a qualitative method with a narrative text analysis approach. The results of this study show that systemic racism plays a role in the level of labor exploitation, economic discrimination, social inequality, and oppressive social norms. Thus, the author's position also shows an effort to criticize the unjust system. However, she notes there are still some limitations since white characters are still central to hold primary control. This study concludes that literary works can function as a medium to voice social criticism of racism, while reflecting the complexity of the author's position in shaping representations of racial injustice.

Abstract

Myth is an important context for societies to negotiate the relationship between humans, nature and values, based on a comparative literary analysis of mythological animals in Eastern and Western Traditions. In Eastern (Asian) traditions mythological figures such as Antaboga, Nyai Roro Kidul and Barong are considered ontological mediators and manifestations of the living ecological order. In Western traditions, by contrast, they are constructed as enemies, monsters or as existential threats to civilization in opposition. In these stories, mythological creatures are ecological boundaries, not hostile boundaries. Such traditions are diametrically opposed to the dominant Western literary paradigm, Beowulf, Moby-Dick and Argonaut, which prioritizes the conquest of monsters and the realization of narrative closure through conquest and control. Within the theoretical framework of this article, carefully grounded in literary form, temporality and the development of the literary canon, legendary creatures serve as vehicles for diverse perceptions of nature. One is founded on dominance and abstraction, the other on reciprocity and moderation. Eastern stories are structured in cycles. Nature’s balance is a dynamic and fragile process. There is no ultimate victory, and it must always be preserved. Meanwhile Western stories are linear and teleological and move toward a definitive end (such as possession or accumulation of wealth) once ecological barriers are removed.
