Abstract

This study aims to determine the impact of controversial figures in marketing strategies in the skincare industry. The research focuses on three public figures: Nikita Mirzani, Dr. Richard Lee, and “Dokter Detektif." This study uses a qualitative study approach to explore the polarization of public image and the role of celebrities in influencing consumer perceptions, brand trust, and purchase intent. Data was collected through social media content analysis, online media documentation, and a literature review of previous studies. The findings reveal three core themes: (1) controversial personal branding attracts engagement and emotional resonance, (2) buzz marketing tactics trigger virality through peripheral cues rather than rational persuasion, and (3) consumer ambivalence emerges between entertainment value and brand credibility. However, the use of controversy also poses long-term reputational risks for the associated brands. Although this study is limited to qualitative methods, it offers theoretical insights and practical recommendations for ethically managing influencer campaigns in culturally sensitive digital markets.

Abstract

Digital transformation can increase competitiveness and customer loyalty and become a business strategy, especially in the context of data security and trust. This study aims to empirically analyze the impact of digital transformation on customer loyalty, emphasizing the mediating role of customer trust at PT Pos Indonesia Pematangsiantar branch. Quantitative research using explanatory surveys of 100 customers selected by purposive sampling technique. The data collection instrument, with the distribution of questionnaires with a Likert scale of 5, has been tested for validity and reliability. Partial Least Squares-Structural Modeling based on SmartPLS 3. The results showed that digital transformation had a significant impact on customer loyalty trust (β = 0.836; p < 0.001) and loyalty (β = 0.906; p < 0.001). However, trust did not significantly impact loyalty (β = 0.076; p < 0.181). The study found that digital transformation can foster loyalty by providing a personalized, secure, and transparent service experience.

Abstract

This study investigates the strategic role of gold as a haven asset amid the anticipated 2025 global tax war, characterised by rising fiscal protectionism, currency volatility, and geopolitical fragmentation. Employing a qualitative literature review, the research synthesises scholarly findings, institutional data, and financial commentary to examine how gold performs under fiscal-driven crises. The findings reveal that gold remains a reliable hedge against inflation, exchange rate risk, and systemic policy shocks, supported by strong institutional trust and long-term investor demand. However, most prior studies focus on financial or monetary crises, leaving a significant gap in understanding gold's behaviour during state-led fiscal confrontations. This paper contributes by framing gold's relevance through a multi-dimensional lens, incorporating macroeconomic policy, digital investment behaviour, and central bank strategy. Further research is recommended to explore the impact of digital gold adoption in emerging markets and its implications for retail investor behaviour.

Abstract

Persediaan adalah salah satu persyaratan utama yang harus dipenuhi dan dimiliki oleh bisnis dalam aktivitas perdagangannya, karena persediaan merupakan tempat transaksi dilakukan. Manajemen persediaan yang kurang baik juga bisa jadi dikarenakan para pelaku usaha yang masa bodoh dan acuh terhadap bagaimana mengelola persediaannya karena beranggapan bahwa yang penting usahanya dapat terus berjalan tanpa tahu sewaktu-waktu usahanya harus tutup karena semakin banyak persediaan yang tidak terjual karena habis masa layak pakainya. CV. Cikini Raya merupakan salah satu usaha yang menyediakan jasa konstruksi di kota Medan. CV. Cikini Raya sendiri dalam memenuhi kebutuhan semen, melakukan pemesanan dengan melihat persediaan bahan baku yang akan habis dan mengakibatkan proses produksi menjadi terhambat. Berdasarkan kondisi tersebut penulis tertarik untuk melakukan kajian ataupun analisis terhadap manajemen persediaan dari CV. Cikini Raya. Jenis penelitian ini merupakan penelitian deskriptif analitik. Hasil dari penelitian ini adalah peramalan terhadap pemakaian semen untuk 48 minggu selanjunya.

Abstract

This study was conducted to analyze the effect of suction power effectiveness on cyclones in Light Tenera Dust Separator (LTDS) 1 and 2 units on the level of palm kernel losses at PTPN IV Regional II Plantation Unit and Adolina Palm Oil Mill (POM). Palm kernel loss is a significant factor that can reduce production efficiency, as palm kernel has high economic value and is the main product in the palm oil industry. Kernel losses not only reduce production efficiency but also create significant economic disadvantages for the palm oil mill. The research method used was a gravimetric method with a field experiment approach. The research process included sampling from LTDS waste, separating kernels from shells, and measuring suction speed using an anemometer to determine cyclone performance. The gravimetric method was applied to quantify the proportion of kernel mixed with shell waste, providing measurable data on suction efficiency. The results showed that low suction power effectiveness was directly proportional to the increasing number of kernels that were thrown away with the shells. In other words, poor suction performance directly correlates with higher kernel losses. The main contributing factors include leaks in the cyclone, suboptimal blower settings, and inadequate operator skills. Operational skills and equipment maintenance were identified as crucial determinants of system performance. Based on these findings, improvements to the suction system are recommended through routine maintenance, leak checks, and blower setting calibration. Furthermore, operator training is required to precisely adjust suction power. By maintaining suction effectiveness and optimizing blower settings, kernel losses can be reduced below the standard threshold of 2.0%. Thus, mills can improve operational efficiency while minimizing economic losses due to palm kernel loss.
