Abstract

Terminalia merupakan salah satu genus pohon besar dalam keluarga Combretaceae. Salah satu spesies dari genus Terminalia yaitu Terminalia mantaly. Memiliki kandungan senyawa kimia yang terdiri dari tanin, flavonoid, terpenoid, lignan, fenol, glikosida, dan poliol yang sering digunakan sebagai obat-obatan. Terminalia memiliki 250 spesies dan 41 spesies yang baru dikaji, 2 diantaranya berasal dari spesies T.mantaly. Pada bagian batang T.mantaly terdapat senyawa yang bersifat semi polar dan belum banyak dieksplorasi maka penelitian ini bertujuan untuk memperoleh isolat murni dari ekstrak etil asetat batang ketapang kencana T.mantaly dan untuk mengetahui senyawa metabolit sekunder yang terkandung dalam isolat murni ekstrak etil asetat batang ketapang kencana T.mantaly. Metode penelitian ini menggunakan true experiment, dimana isolasi pada penelitian ini dilakukan dengan berbagai metode kromatografi. Struktur kimia diidentifikasi berdasarkan 1H-NMR, 13C-NMR, Spektrum FTIR dan massa. Berdasarkan hasil analisis spektroskopi NMR dapat diprediksi bahwa senyawa yang diperoleh dari hasil isolasi ekstrak etil asetat batang ketapang kencana T.mantaly yaitu Stigmasterol.

Abstract

Background: Hand sanitizers generally contain alcohol. However, it can cause dry and irritated skin. Therefore, it is necessary to find antibacterial alternatives that are safe for the skin. One of the plants that has antibacterial activity is Terminalia mantaly (T. mantaly). This study aimed to investigate the antibacterial activity of ethanol extract and hand sanitizer gel of T. mantaly.Methods: The antibacterial activity test against gram-positive (Staphylococcus aureus and Streptococcus pyogenes) and gram-negative bacteria (Escherichia coli and Shigella dysenteriae) was carried out using the liquid micro dilution method. The phytochemical tests were also performed. This study was conducted at the Chemistry Laboratory, Faculty of Sains and Informatics, Universitas Jenderal Achmad Yani in April-June 2022.Results: The ethanol extract of T. mantaly stem contained secondary metabolites of alkaloids, tannins, quinones, saponins, steroids, and flavonoids. The minimum inhibitory concentration (MIC) values of T. mantaly stem ethanol extract against Escherichia coli, Shigella dysenteriae, Staphylococcus aureus, Streptococcus pyogenes were 0.63%, 0.63%, 0.16%, and 0.16%, whereas the hand sanitizer gel gave MIC values of 0.63%; 0.31%; 0.16%; and 0.16% respectively. The minimum bactericidal concentration (MBC) values of T. mantaly stem ethanol extract and hand sanitizer gel had the same results, namely 2.50%, 0.16%, 1.25%, and 1.25%. The physical stability of the hand sanitizer gel from the ethanol extract of T. mantaly stem met the physical stability standards of the gel. Conclusions: The ethanol extract of the T. mantaly stems has stronger antibacterial activity against gram-positive bacteria than against gram- negative bacteria.

Abstract

Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri dari ekstrak etanol daun binahong dan formulasi sabun padatnya. Maserasi menggunakan pelarut etanol 70% digunakan untuk mendapatkan ekstrak etanol daun binahong. Metabolit sekunder dari daun binahong diperoleh dari maserasi menggunakan pelarut etanol 70%. Ekstrak yang diperoleh kemudian dilakukan uji fitokimia, formulasi sabun padat, uji antibakteri, dan uji hedonik. Ekstrak etanol daun binahong mengandung metabolit sekunder golongan flavonoid, saponin, kuinon, dan fenol. Pengujian terhadap sabun padat ekstrak etanol daun binahong mengacu pada SNI 3532-2016. Berdasarkan uji SNI terhadap sabun padat binahong, kadar air berkisar 26 - 28% (SNI <15%); rata-rata pH yaitu 9 (pH SNI 9 – 11), %FFA atau % asam lemak bebas yaitu 0,7896 – 0,9137% (SNI < 2,5%), dan %bahan tak larut dalam etanol yaitu 3,9% dan 4,4% (SNI <5%). Berdasarkan hasil uji sensitivitas, seluruh panelis (n=30) tidak mengalami iritasi. metode kertas digunakan untuk pengujian antibakteri pada ekstrak etanol daun binahong dan sabun padatnya. Hasil pengujian antibakteri menunjukkan bahwa ekstrak etanol daun binahong dan sabun padatnya memiliki daya hambat dengan kategori sedang untuk bakteri Staphylococcusaureus dan Pseudomonas aeruginosa.

Abstract

The rise in perfume usage has led to many brands or companies establishing refill perfume businesses. The refill perfume industry currently faces challenges in building a strong brand image. This research aims to examine the influence of customer experience and word of mouth in establishing the brand image of the refill perfume industry. The method used in this study is a quantitative descriptive approach with Structural Equation Modeling-Partial Least Square (SEM-PLS). The analysis tool used is SmartPLS. The population for this study consists of refill perfume consumers from each branch of refill perfume stores in five major cities in West Java Province: Bandung, Tasikmalaya, Garut, Bekasi, and Cirebon. The minimum sample size taken is 332 respondents, using cluster sampling. The results of this study indicate the influence and significance of customer experience and word of mouth in building the brand image of the refill perfume industry.

Abstract

Brand image remains pivotal in contemporary marketing discourse, particularly within niche industries. This study advances brand theory by empirically examining how product attributes, pricing strategies, service quality, and social media engagement collectively shape the brand image of refill perfumes through customer experience mediation. Employing Structural Equation Modeling–Partial Least Squares (SEM-PLS) via SmartPLS, data from 332 refill perfume customers across five cities in West Java, Indonesia were analyzed using cluster sampling. Findings indicate that all examined factors significantly enhance brand image, with customer experience acting as a crucial mediator. Practically, this suggests that refill perfume businesses can strategically leverage product quality, competitive pricing, superior service, and dynamic social media presence to cultivate a robust brand identity.

Abstract

The company's reputation is one of the most valuable, essential, strategic, and enduring intangible assets a company owned. Reputation is an asset that allows a company to differentiate itself and even allow consumers to pay a premium for products with an exclusive character. This study aims to determine the influence of the E-Value Creation Model and Social Media Marketing in Increasing the E-Reputation of the Perfume Refill Industry. Descriptive quantitative research includes in this study. This study focused on the Malang City refill perfume industry and employed random sampling as a sampling method. As a result, the sample for the study consisted of 159 refill perfume businesses. The data analysis technique in this study used Partial Least Square (PLS). PLS is a structural equation model modeling (SEM) approach based on variance or component-based structural equation modeling. The results showed that E-Value Creation and Social Media Marketing significantly positively influence E-reputation.
