Kopi merupakan salah satu tanaman yang sudah banyak dikenal oleh masyarakat umumnya. Kopi merupakan tanaman yang memiliki kandungan kafein dengan salah satu manfaatnya untuk meningkatkan stamina dan menahan rasa kantuk karena mengandung senyawa alkaloid yaitu kafein. Selain itu, kopi juga memiliki kandungan lain seperti flavonoid, tanin, saponin, dan steroid yang bermanfaat untuk menghambat pertumbuhan bakteri gram postif dan bakteri gram negatif. Penelitian ini bertujuan untuk meneliti aktivitas antibakteri ekstrak etanol biji kopi hijau arabika dan robusta terhadap bakteri Propionibacterium acness. Biji kopi yang digunakan adalah biji kopi yang masih hijau yang belum disanggrai. Metode penelitian yang digunakan adalah penelitian eksperimental laboratorik. Pengujian aktivitas antibakteri dari ekstrak etanol biji kopi arabika dan robusta terhadap bakteri Propionibacterium acnes menggunakan metode difusi sumuran dengan pengukuran diameter zona hambatan. Data dianalisis dengan uji parametrik one way ANOVA. Hasil menunjukkan pada konsentrasi 25%, 50%, dan 75%, ekstrak etanol biji kopi arabika (Coffea arabica) dan robusta (Coffea canephora) memiliki aktivitas antibakteri terhadap bakteri Propionibacterium acness. Diameter zona hambat ekstrak etanol biji kopi arabika konsentrasi 25%, 50%, dan 75% berturut-turut adalah 9,79± 0,36 mm, 11,10 ± 0,34mm, dan 13,90 ± 0,32 mm. Diameter zona hambat ekstrak etanol biji kopi hijau robusta konsentrasi 25%, 50%, dan 75% berturut-turut adalah 8,81± 0,49 mm, 10,37 ± 0,43 mm, dan 10,76 ± 0,29 mm. Hasil uji ANOVA two ways mendapatkan nilai sig < 0,05, sehingga dapat disimpulkan bahwa kedua uji berbeda secara bermakna. Oleh karena itu disimpulkan bahwa ekstrak etanol biji kopi arabika lebih baik dibandingkan ekstrak etanol biji kopi robusta dalam menghambat bakteri Propionibacterium acnes. Meskipun zona hambat konsentrasi ekstrak etanol biji kopi arabika konsentrasi 75% lebih besar dari pada konsentrasi 50%, namun secara statistik ke duanya tidak berbeda bermakna. Oleh karena itu konsentrasi yang paling baik dalam menghambat pertumbuhan bakteri Propionibacterium acnes adalah konsentrasi ekstrak etanol biji kopi arabika 50% atau 75%. Kata kunci : Kopi arabika, kopi robusta, aktivitas antibakteri, Propionibacterium acnes

This study analyzes the fiscal implications of the 3 kg LPG subsidy policy in Indonesia, focusing on its impact on national revenue and regional finance in West Java Province. Employing a descriptive qualitative approach supported by empirical data, the research reveals that although the subsidy aims to improve social welfare by providing affordable energy access for low-income households, it also creates significant fiscal pressure on both national and regional budgets. The findings indicate that the subsidy reduces potential state revenue, narrows fiscal space, and leads to inefficiencies due to mis-targeting and distribution leakages. At the regional level, the subsidy affects budget allocations, limits fiscal flexibility, and increases administrative burdens for monitoring and implementation. The case study in West Java illustrates how the suboptimal management of the subsidy generates a trade-off between achieving social goals and maintaining fiscal sustainability. Therefore, policy reforms are needed, including digitalized distribution systems, improved beneficiary targeting, and stronger fiscal coordination between central and local governments. This research contributes to the development of more efficient and sustainable energy subsidy policies and supports the improvement of public financial governance that is transparent and accountable at both national and subnational levels.

This study aims to analyze public awareness, perception, and acceptance of the implementation of the Digital Population Identity (DIC) policy in Pontianak City. Using a theoretical framework that integrates the technology acceptance model (TAM), the theory of risk and negative consequences, and the theory of organizational trust, this study explores factors such as usefulness, ease of use, user experience, social influence, facilitating conditions, awareness, perception, and public acceptance of DIC. A questionnaire-based survey was applied to the Pontianak City community selected through a stratified random sampling method. Data analysis was carried out using descriptive and inferential statistics to identify relationships between variables and evaluate factors that influence DIC adoption. The findings of this study are expected to provide relevant information for policymakers to develop strategies for implementing more adaptive and inclusive DIC policies. In addition, this study also identifies local challenges in implementing DIC, including data security and technology access, which can be a basis for developing digital policies in the future.
