Abstract

Tujuan penelitian ini untuk mengetahui pengaruh kualitas pelayanan dan fasilitas kampus terhadap kepuasan mahasiswa angkatan 2018-2021 di Institut Teknologi & Bisnis Master Pekanbaru. Objek penelitian adalah seluruh mahasiswa Institut Teknologi & Bisnis Master Pekanbaru, dari angkatan 2018-2021 dengan total mahasiswa sebanyak 998 orang mahasiswa dengan sample sebanyak 90 orang mahasiswa. Teknik analisis yang di gunakan teknik analisis regresi linear berganda dengan menggunakan uji validitas, uji reliabilitas, uji normalitas, uji R2, uji T dan uji F. Berdasarkan hasil penelitian diperoleh bahwa variabel kualitas pelayanan dengan nilai t-hit sebesar 6,286 dan nilai t-tab sebesar 1,987. Sehingga t-hit > t-tab sehingga 6,286 > 1,987 yang artinya Kualitas Pelayanan (X1) secara parsial berpengaruh signifikan terhadap kepuasan mahasiswa (Y) di Institut Teknologi Dan Bisnis Master Pekanbaru. Sedangkan variabel fasilitas kampus dengan nilai t-hit sebesar 3,404 dan nilai t-tab sebesar 1,987. Sehingga t-hit > t-tab sehingga 3,404 > 1,987 yang artinya fasilitas kampus (X2) secara parsial berpengaruh signifikan terhadap kepuasan mahasiswa (Y) di Institut Teknologi Dan Bisnis Master Pekanbaru. Dengan demikian maka Ho ditolak dan H1 diterima. Artinya terdapat pengaruh secara signifikan antara kualitas pelayanan dan fasilitas kampus dengan kepuasan mahasiswa angkatan 2018-2021 di Institut Teknologi & Bisnis Master Pekanbaru. Kesimpulannya adalah bahwa nilai Adjusted R Square sebesar 0,704 atau 70,4% berarti kualitas pelayanan dan fasilitas kampus berpengaruh signifikan terhadap kepuasan mahasiswa angkatan 2018-2021 di Institut Teknologi & Bisnis Master Pekanbaru.

Abstract

Biosynthesis of silver nanoparticles (AgNPs) using ketapang leaf extract, modification with p-coumaric acid for detecting melamine has conducted. This research aimed to synthesize AgNPs via bio-reduction method using ketapang leaf extract followed by modification with p-coumaric acid (APK), and evaluating its application detecting melamine. The AgNPs were characterized through ultraviolet-visible absorption spectroscopy (UV-Vis) and X-ray diffraction (XRD). Observation suggested that an increase of incubation time had affected its surface Plasmon resonance trend. Further analysis of crystallite via XRD suggested that nanoparticle size at 43 nm estimated using Debye-Scherer, within the form of unit cells is cubic. The performance of product as melamine detector suggested that the AgNPs-APK had detected melamine in range of concentration from 0.1 to 1000 ppm.

Abstract

The research aims to synthesis of silver nanoparticles (AgNPs) via bio-reduction method using mangosteen skin extract. The growth of AgNPs was characterized by ultraviolet-visible spectroscopy (UV-Vis). Based on Surface Plasmon resonance (SPR) data, observation suggested that an increase of initial AgNO3 concentration along with temperature, had affected its surface Plasmon resonance trend. SPR absorption indicates that the concentration of AgNO3 and the synthesis temperature was instrumental in the formation of silver nanoparticles.

Abstract

Biosynthesis of silver nanoparticles (AgNPs) using mangosteen bark extract, modification and its application in detecting melamine has conducted. This research aimed to synthesize AgNPs via bio-reduction method using mangosteen bark extract followed by modification with p-coumaric acid (APK), and evaluating its application detecting melamine. The AgNPs were characterized through ultraviolet-visible absorption spectroscopy (UV-Vis), Fourier transform infrared absorption spectroscopy (FTIR), and X-ray diffraction (XRD). Observation suggested that an increase of incubation time had affected its surface Plasmon resonance trend. Observation of functional group by FTIR showed that carbonyl group (1707 cm-1) suspected from hydroxyl group (3414 cm-1). Further analysis of crystallite via XRD suggested that nanoparticle size at 30 nm estimated using Debye-Scherer, within the form of unit cells is cubic. Modified AgNPs showed an interaction between APK and particle surface through C=C alkenes (1598 cm-1) and aromatics (1672 cm-1), =C-H aromatic (3070 cm-1), aliphatic C-H (2501 cm-1), C-O (1107 cm-1) and C=O carboxylate (1774 cm-1). The performance of product as melamine detector suggested that the AgNPs-APK had detected melamine in range of concentration from 0.1 to 1000 ppm.

Abstract

The adsorption of Bismarck Brown R (BBR) dye has been conducted using mesoporous silica (MCM-48). We synthesized the adsorbent using Ludox HS-40 as a silica source and surfactants of Cetyl Trimethylammonium Bromide (CTAB) and Triton X-100. The characterization of MCM-48 was performed using Fourier transform infrared (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Various contact times were used to study the adsorption kinetics, and concentrations were used to study the adsorption isotherm. The optimum contact time of Bismarck Brown R dye was 120 minutes, and the adsorption followed a pseudo-second-order model. Based on the equation Langmuir and Freundlich adsorption isotherms, the adsorption capacity values of each are obtained 158.7301 mg g-1 and 4.3601 mg g-1. Our results showed that the material can be used as a new dye adsorbent.

Abstract

Our present study describes the green synthesis of copper oxide nanoparticles (CuONPs) using a leaf extract from Anredera cordifolia (AC). The presence of flavonoids, saponins, and alkaloids in the plant extract was confirmed by phytochemical analysis, and these chemicals can be used as reducing, stabilizing, and capping agents. UV-Vis Spectrophotometry, XRD, FT-IR, and SEM-EDS were used to characterize the CuONPs. The UV-Vis spectroscopy of the biosynthesized CuONPs revealed an absorption peak at 325 nm. The XRD graph also revealed that the Debye-Scherrer formula observed an average crystalline size of around 43.47 nm. EDS analysis confirmed the composition and purity of CuONPs. The presence of functional groups -OH, C=O, and C-O triggers the synthesis of CuONPs, according to FT-IR analysis. Furthermore, the CuONPs antioxidant property inhibited free radicals as antioxidants with an IC50 value of 34.20 g/mL.

Abstract

This research aims to synthesize and characterize reduced graphene oxide (RGO), as well as analyse its electrochemical properties. The synthesis of RGO material from corn cobs went through several stage: carbonization, oxidation and reduction. The synthesis of RGO used a modified Hummer method, and was reduced using the reducing agent ascorbic acid. The synthesized RGO was then characterized using Fourier Transform Independent Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Energy Dispersive Spectroscopy (EDS). Electrochemical analysis using the cyclic voltammetry method, the specific capacitance value obtained showed that RGO had a higher capacitance value than GO. The research results showed that carbon from corn cobs, which has not been utilized optimally, can be synthesized as a basic material for making RGO as a quite promising material.

Abstract

This research aims to examine the transformation of Multi Level Marketing (MLM) marketing strategies in facing global challenges caused by developments in digital technology, changes in consumer behavior and globalization. In this context, this research focuses on how MLM companies adapt and implement new marketing strategies to remain relevant and competitive. The research method used is a qualitative method with a case study approach. Data was collected through in-depth interviews with executives, marketing managers, and main distributors from several different MLM companies. In addition, content analysis was carried out on the digital marketing materials used by these companies. Data analysis was carried out using thematic analysis techniques to identify main patterns and themes that emerged from the data. The research results show that MLM companies that are successful in transforming their marketing strategy tend to integrate digital technology such as social media, mobile applications and e-commerce platforms in their operations. Additionally, they emphasize transparency and building trust with customers and distributors through open and honest communication. This research also found that adapting to local needs and preferences is very important in global marketing strategies. Innovation in products and services as well as compliance with regulations and business ethics are key factors that support the successful transformation of MLM marketing strategies.
