Abstract

Abstrak Daun cabe jawa (Piper retrofractum Vahl.) telah terbukti berkhasiat sebagai bahan antimikroba, akan tetapi belum ada informasi lebih lanjut tentang mekanisme aksi antibakteri dari minyak atsiri daun cabe jawa. Penelitian ini untuk mengetahui pengaruh minyak atsiri daun cabe jawa terhadap bakteri uji sensitif serta difokuskan untuk melihat kerusakan membran sel bakteri melalui analisis protein, asam nukleat dan ion-ion logam kalsium dan kalium. Distilasi uap minyak atsiri dari daun segar cabe jawa (Piper retrofractum Vahl.) menghasilkan 0.03% cairan kental kekuningan. Analisis dengan GC-MS mengidentifikasi 4 senyawa sebagai komponen utama, yaitu germakren D (24.20%), tetrametilsiklo[5.3.1.0(4.11)]-undek-8-ena (17.73%), ar-turmeron (11.55%) dan benzil benzoat (6.28%). Minyak atsiri cabe jawa terbukti aktif melawan beberapa bakteri patogen antara lain Staphylococcus aureus, Bacillus subtilis and Micrococcus luteus dengan diameter daya hambat berturut-turut 8.0; 9.7; 8.5 mm. Pengamatan lebih lanjut memperlihatkan nilai MIC dari minyak atsiri cabe jawa  terhadap B. subtilis adalah 2% (v/v), dan juga merubah morfologi sel dari bakteri yang diobservasi menggunakan SEM. Kata kunci: Piper retrofractum Vah., cabe jawa, minyak atsiri, aktivitas antibakteri Abstract The leaves of Javaneese pepper (Piper retrofractum Vahl.) has been proven efficacious as antimicrobial agent, however, there was no further information about action mechanism of antibacterial of Javaneese pepper leaves essential oil. This study was to determine the effect of essential oils of javaneese pepper leaves against bacterial sensitive test and is focused on investigating the damage of cell membranes of bacteria through the analysis of proteins, nucleic acids and metal ions, calcium and potassium. Steam distillation of essential oil from fresh leaves of Javaneese pepper (Piper retrofractum Vahl.) gave 0.03 % yellowish viscous liquid. Germacrene D (24.20 %), tetramethylcyclo[5.3.1.0(4.11)]-undec-8-ene (17.73 %), Ar-turmeron (11.55 %) and benzyl benzoate (6.28 %) were identified as major constituents analyzed by GC-MS. Javaneese pepper essential oil was active against pathogenic bacteria Staphylococcus aureus, Bacillus subtilis and Micrococcus luteus with diameter of clear zone of 8.0, 9.7 and 8.5 mm respectively. Further investigation showed MIC value of the oil against B. subtilis was 2 % (v/v), and was also alter the cell morphology of tested bacterium observed by SEM. Key words: Piper retrofractum Vahl., Javeneese pepper, essential oil, antibacterial activity

Abstract

In the era of the Industrial Revolution 4.0, the development of digital technology and the internet has changed the way people work, interact and access information. Geography plays an important role in managing this change, including in the development of digital infrastructure, spatial data analysis, and supply chain management. Geography also plays a role in supporting integration between physical and digital sectors, such as location-based logistics and smart city center development. Society 5.0, which emphasizes combining digital technology with a human-centred society, requires a deep understanding of the interrelationships between humans, the environment and technology. Geography can help map and analyze social, cultural and economic dynamics in society 5.0. Through a geospatial approach, geography can also integrate data and knowledge across sectors to facilitate better decision-making in addressing complex challenges, such as climate change, social inequality and natural resource management. In this era, geography also plays a role in developing sustainable development concepts and strategies. By considering geographical aspects such as location, environmental conditions, and resource availability, geography can help plan environmentally friendly infrastructure development, increase resilience to natural disasters, and optimize the efficient use of resources. In conclusion, geography has an important role as the axis of development in the era of the Industrial Revolution 4.0 and Society 5.0. The discipline of geography starting from elementary school to the highest level is needed to assist in the management of technological and societal changes, socio-economic analysis, and the development of sustainable development strategies. In facing future challenges, the application of geographic knowledge is the key to achieving sustainable and inclusive development.

Abstract

The development of culinary tourism as one of the fastest-growing tourism segments requires strategic decision-making that is responsive to tourist preferences, market dynamics, and local culture. This article examines the role of intuitive decision-making in formulating and implementing business strategies for culinary tourism, with a case focus on Tanjungpinang. Using a literature review method, the article synthesizes theories and empirical findings on intuition in managerial decision-making as well as practices in culinary tourism development in Indonesia and the Riau Islands region. The results show that intuitive decisions—shaped by experience, tacit knowledge, and rapid information processing—play an important role when information is limited, time is constrained, or market conditions change quickly. However, intuition becomes effective when combined with data-based verification mechanisms and stakeholder collaboration. Practical implications for business actors and local policymakers include: (1) strengthening the experiential capabilities of culinary business managers; (2) integrating intuition with practices of monitoring visitor data and tourist feedback; and (3) developing culinary experience packages that highlight the local uniqueness of Tanjungpinang. Suggestions for future research emphasize empirical field studies on the relationship between intuition, business performance, and tourist satisfaction in Tanjungpinang.
