Abstract

Machining is a metal cutting process using a machine tool. The machining process will produce the products and the chips or the scraps. The metal of machining chips made from machining processes can be recycled into new materials. The metal of machining chips can be recycled through the smelting process. This research aims to design and fabrication a crucible furnace that can support the recycling process of the metal scraps of machining chips into a new material—the stove is designed to melt non-ferrous metals using gas fuel. The tilting-pot crucible furnace type was created in this research. The crucible furnaces are used for nonferrous metals such as bronze, brass, zinc, and aluminum alloys. The crucible furnace capacities are limited to 10 kg. Liquefied Petroleum Gas (LPG) was used as the fuel for the furnace. The construction of the stove is cylindrically designed. The burner was installed upright at the bottom of the stove. The combustion process is done by mixing fuel LPG gas and air from the blower. The stove was tested on the aluminum machining chips using locally available materials in Lhokseumawe Aceh. The thermometer Lutron TM-906A was used to measure the temperature inside the crucible. From the results of the design and testing of the furnace that has been done, it can be concluded that the aluminum machining chips of 6kg are melting at a temperature of 640oC for 52 minutes, and the LPG gas fuel required is 1.30kg. The crucible furnace was designed to attain a maximum temperature of 700°C.

Abstract

This study aims to analyze the influence of social media marketing on purchase intention, mediatedby brand awareness and consumer brand engagement, among consumers of fashion clothing products in Lhokseumawe City. The background of this research is based on the increasing use of social media as a marketing tool in the fashion industry and the high consumer exposure to fashion content that does not necessarily translate into purchase intention. The method used in this study is a quantitative approach with data analysis techniques using SEM based on Partial Least Squares (PLS). Data were obtained through direct questionnaires distributed to 105 respondents who are social media users and interested in fashion clothing products in Lhokseumawe City. The results show that social media marketing has a positive and significant effect on brand awareness, consumer brand engagement, and purchase intention. Furthermore, brand awareness and consumer brand engagement have a positive and significant effect on purchase intention. Brand awareness and consumer brand engagement also mediate the effect of social media marketing on purchase intention. These findings indicate that social media marketing is a significant factor in increasing consumer purchase intention for fashion products, both directly and through increasing brand awareness and consumer engagement with the brand.

Abstract

This study aims to analyze the influence of Endorsement Influencer, Immersive Experience, and User Generated Content (UGC) on Purchase intention of Roblox virtual items, with Trust as a mediating variable. The respondents were 96 active students at the Faculty of Economics and Business, Universitas Malikussaleh, who had previously purchased virtual items on Roblox. Data were collected through questionnaires and analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) with SmartPLS. The results indicate that Immersive Experience has a positive and significant effect on Trust, Trust positively and significantly affects Purchase Intention, and UGC positively and significantly affects Purchase Intention. Conversely, Endorsement Influencer does not significantly affect Trust or Purchase Intention, Immersive Experience does not significantly affect Purchase Intention, and UGC does not significantly affect Trust. Furthermore, Trust fails to mediate the relationships between Endorsement Influencer, Immersive Experience, nor UGC on Purchase Intention. These findings suggest that Trust and UGC are the most dominant factors in driving virtual item purchase intentions, while influencer marketing and immersive experiences alone remain insufficiently effective without robust user trust.

Abstract

This study examines how travel influencer attractiveness, trustworthiness, and content expertise influence behavioral intention to visit recommended post-disaster destinations through attitude toward a travel influencer. The research focuses on Central Aceh and Bener Meriah, Indonesia, and applies the Stimulus-Organism-Response framework. An online questionnaire yielded 155 eligible responses from Aceh residents who used TikTok, had viewed travel influencer content, and had previously visited either destination. Data were analyzed using partial least squares structural equation modeling in SmartPLS. Attractiveness and content expertise positively influenced attitude, whereas trustworthiness did not have a significant effect. Attitude and attractiveness positively influenced behavioral intention, while the direct effects of trustworthiness and content expertise were not significant. Attitude partially mediated the attractiveness-intention relationship and fully mediated the content expertise-intention relationship; the trustworthiness-mediated relationship was not significant. The model explained 74.0% of the variance in attitude and 78.3% in behavioral intention. Content expertise was the strongest predictor of attitude. The findings support selecting influencers for their content competence and appealing presentation, while emphasizing favorable audience attitudes in post-disaster tourism communication.

Abstract

This study examines the role of brand awareness in mediating the effects of taste, brand trust, perceived quality, and brand love on tourist purchasing decisions for Gayo Arabica Coffee in Central Aceh Regency. All variables were measured using a Likert scale. Primary data were collected through questionnaires administered to 210 tourists who had purchased or consumed Gayo Arabica Coffee while visiting tourist destinations in Central Aceh Regency. The data were analyzed using path analysis with WarpPLS version 7.0. The results show that taste, perceived quality, and brand love significantly affect brand awareness, whereas brand trust does not. Brand awareness, brand trust, and brand love significantly affect tourist purchasing decisions, whereas taste and perceived quality do not have significant direct effects. Path analysis further shows that brand awareness mediates the effects of taste, perceived quality, and brand love on tourist purchasing decisions, but does not mediate the effect of brand trust. These findings position brand awareness as an important intervening mechanism in tourists’ purchasing decisions for Gayo Arabica Coffee.

Abstract

Rantai pasok pada industri makanan laut beku memiliki tingkat risiko yang relatif tinggi akibat ketidakpastian pasokan bahan baku, fluktuasi harga, serta tuntutan kualitas produk dan ketepatan waktu pengiriman, khususnya pada pasar ekspor. PT. XYZ sebagai perusahaan eksportir frozen seafood menghadapi berbagai risiko rantai pasok yang berpotensi mengganggu kelancaran operasional dan pencapaian kinerja perusahaan. Oleh karena itu, diperlukan suatu pendekatan manajemen risiko yang mampu menganalisis dan menentukan prioritas risiko secara sistematis dan objektif. Penelitian ini bertujuan untuk menentukan risiko prioritas, serta memberikan usulan strategi mitigasi yang tepat dan sistematis menggunakan metode Fuzzy Failure Mode and Effects Analysis (Fuzzy FMEA). Penilaian risiko dilakukan menggunakan tiga parameter utama FMEA, yaitu Severity, Occurrence, dan Detection, yang dinyatakan dalam bentuk variabel linguistik dan diolah menggunakan sistem inferensi fuzzy Mamdani untuk menghasilkan nilai Fuzzy Risk Priority Number (FRPN). Hasil penelitian yang didapat menunjukan bahwa nilai FRPN berada pada rentang 6,66 hingga 8,63, dengan nilai rata-rata sebesar 7,72 dan standar deviasi 0,63, sehingga diperoleh nilai cut-off sebesar 8,35. Berdasarkan kriteria tersebut, risiko keterlambatan pasokan bahan baku (R1) dengan nilai FRPN 8,61 dan fluktuasi harga bahan baku (R3) dengan nilai FRPN 8,63 ditetapkan sebagai risiko prioritas tinggi. Risiko prioritas selanjutnya dianalisis menggunakan metode 5 Why Analysis untuk mengidentifikasi akar penyebab utama risiko. Usulan mitigasi risiko prioritas difokuskan pada penguatan manajemen pemasok melalui evaluasi dan diversifikasi supplier, penyusunan kontrak harga jangka menengah, peningkatan sistem perencanaan pengadaan berbasis proyeksi, serta monitoring pasokan dan harga bahan baku secara berkala.
