Strategi Influencer Marketing dan Tantangan Vampire Effect dalam Pembentukan Identitas Merek di Kalangan Gen Z
Get PDFThis study aims to analyze the effect of influencer credibility on influencer popularity, as well as to examine the role of the vampire effect as a moderating variable in the context of digital marketing strategies targeting Gen Z. The background of this research is driven by the growing use of influencers in digital marketing strategies, while challenges remain when the influencer’s persona becomes more dominant than the brand message delivered. A quantitative approach was employed, using a survey method targeting Gen Z respondents in Indonesia. Data were analyzed using linear regression and moderation testing. The results indicate that influencer credibility has a positive but insignificant effect on influencer popularity. Meanwhile, the vampire effect has a direct influence on influencer popularity but does not significantly moderate the relationship between influencer credibility and popularity. The managerial implication of this study suggests that companies should carefully consider influencer credibility while anticipating the potential impact of the vampire effect when selecting influencers as part of digital marketing strategies. Furthermore, this research opens opportunities for future studies using a mixed-method approach, as well as exploring other variables such as audience involvement and emotional engagement

Get PDFTuberkulosis paru (TBC paru) masih menjadi masalah kesehatan utama di Indonesia, terutama bila disertai diabetes melitus tipe 2 (DM tipe 2) yang dapat menurunkan imunitas dan meningkatkan inflamasi sistemik. Rasio neutrofil-limfosit (NLR) merupakan indikator sederhana untuk menilai tingkat inflamasi, sedangkan derajat lesi radiografi toraks menggambarkan tingkat keparahan penyakit paru. Penelitian ini bertujuan untuk mengetahui karakter luas derajat lesi dan hubungan antara derajat lesi radiografi toraks dengan nilai NLR pada pasien TBC paru dewasa disertai DM tipe 2 terkontrol di RSU Royal Prima Medan periode 2024. Desain penelitian menggunakan metode observasional analitik dengan pendekatan cross sectional pada 32 pasien. Data diperoleh dari hasil pemeriksaan radiografi toraks, laboratorium, dan rekam medis, kemudian dianalisis menggunakan uji Chi-Square dengan tingkat signifikansi p < 0,05. Hasil menunjukkan bahwa sebagian besar pasien memiliki derajat lesi Moderately Advanced (37,5%), dan kategori NLR terbanyak adalah intermediate inflammation (43,8%). Uji Chi-Square menghasilkan p = 0,960 (p > 0,05), sehingga tidak terdapat hubungan signifikan antara derajat lesi radiografi toraks dan nilai NLR. Kesimpulannya, tingkat keparahan lesi paru tidak selalu berbanding lurus dengan tingkat inflamasi sistemik pada pasien TBC paru dengan DM tipe 2 terkontrol. Disarankan pasien tetap menjaga kontrol glukosa darah, sementara fasilitas kesehatan memperkuat skrining TB-DM dan pemantauan biomarker inflamasi

Get PDFThis study analyzes the budget efficiency of the Mamminasata Bypass Road and Bridge Construction Project Segment I and II using the Cost Performance Index (CPI) from the Earned Value Management (EVM) method. This project has a contract value of IDR 139.90 billion and an implementation period from November 2022 to March 2024. The data used is secondary data in the form of monthly progress reports, financial statements, and contract documents. The parameters analyzed included Planned Value (PV), Earned Value (EV), Actual Cost (AC), CPI, Cost Variance (CV), and Schedule Performance Index (SPI). The results showed an average CPI value of 0.99, which indicates excellent budget efficiency with a cost overrun of only 0.99%. CPI fluctuations over the course of the project are relatively minimal, indicating the stability of cost performance. Multiple regression analysis identified four significant factors that affect budget efficiency, namely soil conditions (β = -0.412, p = 0.005), design changes (β = -0.289, p = 0.010), volume changes (β = -0.198, p = 0.043), and price escalation (β = -0.367, p = 0.001), with the regression model having R² = 0.847. A comparison of budget efficiency between Segments I and II showed no significant difference (p-value = 0.682), with Segment I CPI 0.990 and Segment II 0.989. This study contributes to the implementation of EVM in road projects in Indonesia and recommends the use of CPI as an effective monitoring tool for controlling the cost of infrastructure projects
