Tujuan penelitian ini untuk menganalisis faktor apa saja yang berpengaruh terhadap keputusan pembelian konsumen kopi di Coffee Shop, menganalisis faktor apa saja yang berpengaruh terhadap perilaku konsumen dalam melakukan pembelian kopi di coffee shop. Penelitian ini dilakukan dengan metode survei Metode pengambilan sampel pada penelitian ini akan dilakukan dengan metode Non-Probability Sampling yaitu convenience sampling. Teknik analisis yang digunakan yakni analisis deskriptif kuantitatif menggunakan Structural Equation Modelling (SEM) PLS. Hasil analisis menunjukan bahwa dari lima variabel yakni atmosfir, harga, kualitas pelayanan, kualitas produk, dan lingkungan, hanya variabel harga yang berpengaruh terhadap keputusan pembelian kopi di coffee shop dengan P-values sebesar 0,013 (<0,05). Diantara tiga variabel yakni, kualitas pelayanan, kepuasan konsumen dan kualitas produk, hanya variabel kepuasan konsumen yang berpengaruh terhadap loyalitas kondumen, dengan P-values sebesar 0,000 (<0,05). Sementara, hanya variabel kualitas pelayanan yang berpengaruh signifikan terhadap kepuasan konsumen dengan P-values sebesar 0,000 (<0,05).

“…Ethanol extracts from C. taxifolia and C. peltata have strong activity with IC50 values of 12.31 mg/L and 12.69 mg/L. Analianasari et al (2022) stated that an IC50 value of less than 50 mg/L is classified as having strong antioxidant activity, 50-100 mg/L is moderate, 150-200 mg/L is weak, and more than 200 mg/L is very weak. A low IC50 value indicates a strong ability of the extract to act as a hydrogen atom donor (Cao et al 2023).…”

Abstract. Akbar SA, Hasan M, Afriani S, Nuzlia C. 2023. Evaluation of phytochemical composition and metabolite profiling of macroalgae Caulerpa taxifolia and C. peltata from the Banda Aceh coast, Indonesia. Biodiversitas 24: 5283-5292. The study of seaweeds to extract their bioactive compounds has become increasingly important from the standpoint of broader applications. This study aimed to examine the metabolite profiles and phytochemical content of Caulerpa peltata and Caulerpa taxifolia along the coast of Banda Aceh in Indonesia. Readers interested in learning more about the biological activities of C. peltata and C. taxifolia can refer to the material gathered from this study. The three steps proposed by this study were phytochemical composition, antioxidant scavenging, and in vivo metabolite profiling by the use of Gas Chromatography-Mass Spectrometry (GC-MS), Fourier Transform Infrared (FTIR) characterization, and the 2,2-diphenylpicrylhydrazyl (DPPH) test. Using DPPH to measure antioxidant activity, both extracts demonstrated greater scavenging capability, with inhibition values of 42.59% and 39.81%, respectively. In both macroalgae, the GC-MS methodology has shown to be a quick, sensitive, and trustworthy way to monitor individual components and the entire chemical composition. In C. taxifolia, there are 29 phytochemical compounds, whereas in C. peltata, there are 26 types. The ethanol extract of the macroalgae C. taxifolia and C. peltata was then subjected to an FTIR spectrum. These findings at 3352 cm-1, 1654 cm-1, and 1019 cm-1 proved that alkanes, alkenes, and hydroxyl groups were present, corresponding to several compounds in the GC-MS measurement results. Caulerpa taxifolia and C. peltata are potential antibacterial agents; the bioactive compounds for this activity are Heptadecane, Hexadecanoic acid, and other ester derivatives.

“…Refers to the results, the IC50 of the ethyl acetate and ethanol leaves extracts of Blumea balsamifera and Cordyline fruticosa extracts were determined as shown in Table 3. The antioxidant activity of IC50 had a classification of the antioxidant activities compound based on the acquisition of the IC50 value as shown as Table 4 (Analianasari et al, 2022). Several studies about Blumea balsamifera, especially the leaves part informed fresh and dry leaves had antioxidant activity with boiling water method, antidiabetic activity with hydro-ethanol extract, antitumor activity with essential oil extract and also anticancer activity of ethyl acetate extract fraction (Widhiantara & Jawi, 2021).…”

Plant use as traditional medicine is still widely practiced in Indonesia. Muara Tae tribe people, West Kutai regency are one of the regions that still rely on Blumea balsamifera and Cordyline fruticosa plants as traditional medicine. This study aims to determine the potential of Blumea balsamifera and Cordyline fruticosa leaves as medicinal plants with phytochemicals and antioxidants. Phytochemical analysis was tested using Harborne and Kokate methods. Antioxidant activity was evaluated by DPPH radical scavenging assay with slight modification. The results of the phytochemical analysis showed that the extracts of n-hexane, ethyl acetate, and ethanol from the leaves of Blumea balsamifera and Cordyline fruticosa contained alkaloids, tannins, and triterpenoids. Antioxidant activity of Blumea balsamifera leaves extract showed that the n-hexane extract display an ability to inhibit DPPH free radical by 50% at 100 ppm concentration, while ethyl acetate and ethanol extracts display an ability by 77% and 81% at 50 ppm concentration. IC50 value of ethyl acetate and ethanol extracts of Blumea balsamifera leaves sequentially were 23.68 µg/mL and 17.59 µg/mL. Antioxidant activity of Cordyline fruticosa leaves extract showed that the n-hexane and ethyl acetate extract display an ability to inhibit DPPH free radical by 45% and 56% at 100 ppm concentration, while ethanol extracts display an ability by 76% at 50 ppm concentration. IC50 value of ethyl acetate and ethanol extracts of Cordyline fruticosa leaves sequentially were 73.72 µg/mL and 20.17 µg/mL. Based on the results, Blumea balsamifera and Cordyline fruticosa leaves extracts had the potential to develop as natural antioxidants.
