Abstract

The Baitul Quran located in Pekanbaru, is relatively new, which means it has a lot of vacant land. As a result, tree planting is necessary to beautify the environment. Similarly, Pekanbaru Sports High School also has vacant land that needs to be utilized. The methods employed sosialization, planting practise, and evaluation. Sosialization is conducted to enhance the partners' knowledge about the role of trees in mitigating the effects of climate change. Tree planting and maintenance practices are implemented to ensure that partners are capable of planting and caring for trees, contributing to the reduction of global warming. The results at Ponpes Baitul Quran and Pekanbaru Sports High School indicate an increase in student knowledge about climate change. Although students at both schools have a similar understanding of climate change, students at Pekanbaru Sports High School demonstrate a stronger grasp of climate change. In contrast, students at Ponpes Baitul Quran show a better understanding of the practical aspects of planting and maintaining trees. Tree planting on the vacant land at these schools creates microclimate. The survival of the trees ranges from 95% to 99%. The best growth in durian trees, followed by eucalyptus, with areca nut trees showing the lowest.

Abstract

Jerawat merupakan salah satu masalah kulit yang umumnya disebabkan oleh aktivitas bakteri, salah satunya adalah Staphylococcus aureus. Saat ini, penggunaan obat jerawat sintetis masih menjadi pilihan utama dalam penanganannya. Namun, pemakaian jangka panjang terus-menerus berpotensi menimbulkan efek samping dan resitensi bakteri. Oleh karena itu, pemanfaatan bahan alam sebagai antiacne alami terus dikembangkan karena dinilai lebih aman. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri kombinasi ekstrak Cymbopogon nardus dan Curcuma longa terhadap Staphylococcus aureus. Uji antibakteri dilakukan menggunakan metode difusi cakram pada pada ekstrak tunggal dan kombinasi. Hasil penelitian menunjukan bahwa pada konsentrasi 50% dan 75%, ekstrak tunggal Cymbopogon  nardus menghasilkan zona hambat sebesar 7,32 dan 8,25 mm, sedangkan Curcuma longa dengan zona hambat 8,35 dan 8,60 mm. Kombinasi ekstrak Curcuma longa + Cymbopogon nardus pada konsentrasi 75 % (50% Curcuma longa dan 25% Cymbopogon nardus) menunjukan zona hambat yang lebih besar, yakni 11,29 mm, dibandingkan kombinasi ekstrak Cymbopogon nardus + Curcuma longa pada konsentrasi yang sama dengan zona hambat sebesar 10,31 mm. Meskipun demikian, kedua kombinasi ekstrak menunjukkan adanya efek sinergis, sehingga ekstrak Cymbopogon nardus dan Curcuma longa berpotensi dikembangkan sebagai bahan aktif kosmetik alami antiacne.
