Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh secara parsial dan simultan variabel fasilitas, lokasi, promosi dan kualitas pelayanan terhadap keputusan berkunjung pada Taman Hutan Kota Langsa. Metode analisis yang digunakan menggunakan kuantitatif analisis regresi berganda. Hasil regresi linear berganda dalam penelitian ini adalah  Y= -0,995 + 0,199 X1 + 0,616 X2 + 0,075 X3  + 0,316 X4. Hasil uji t menyatakan bahwa fasilitas, lokasi dan kualitas pelayanan memiliki pengaruh yang signifikan terhadap keputusan berkunjungpada Taman Hutan Kota Langsa. Sedangkan variabel promosi (X3) tidak memiliki pengaruh yang signifikan terhadap keputusan berkunjung pada Taman Hutan Kota Langsa. Hasil uji F menyatakan bahwa variabel fasilitas (X1), lokasi (X2), promosi (X3) dan kualitas pelayanan (X4) memiliki pengaruh terhadap keputusan berkunjung (Y). Hasil uji R Square diperoleh nilai sebesar 0,690 atau 69,0%, hal ini bearti variabel fasilitas, lokasi, promosi dan kualitas pelayanan mempengaruhi keputusan berkunjung pada Taman Hutan Kota Langsa sebesar 69,0% dan sisanya sebesar 31,0% dipengaruhi oleh variabel lain yang tidak diteliti dalam penelitian ini

Abstract

This study aims to determine the effect of Fe3O4 nanocomposite composition: Graphene Oxide on the optical properties of Fe3O4 Graphene Oxide nanocomposite by obtaining the results of absorbance value, transmittance, reflectance, and band gap value based on UV-Vis test. Graphene oxide used in this study is made from biomass waste coconut shell charcoal which contains carbon elements, most of whose pores are still covered by hydrocarbons and other organic compounds and the charcoal is used as activated carbon through an activation process, then synthesized using the modified hummers method. In this study, three variations were used, namely 20%: 80%; 30%; 70%; 40%: The results show that the effect of Fe3O4-Graphene Oxide Nanocomposite Composition on coconut shell waste using a UV-Vis spectrometer, the absorbance value of each sample was obtained in the range of 200-290 nm.. In the results of gap energy research with 3 variations respectively 3.269 eV, 3.79 eV, 3.91 eV obtained that if the variation of graphene oxide is higher than the value of the energy gap produced is smaller, so the addition of graphene oxide from coconut shell waste has the effect of reducing the energy gap of graphene oxide.
