Indonesia as the largest archipelago country in the world is also known as a country with plenty of natural resources that can be used as traditional medicinal plants. Pliek U is a fermented crude coconut meat has been used as an ingredient in Aceh traditional food and also used as a traditional topical medicine in Aceh. Pliek U is potential as a source of free fatty acids (FFAs) such as lauric acid and monolauric acid which have antimicrobial properties. The aim of this study is to determine the activity ethanolic Pliek U extracts (EPUE) and ethanolic of residue hexane of Pliek U extracts (ERHPUE) and also the activities of their cream formulation against Staphylococcus aureus The antibacterial activity was determined by disc difussion method with clindamycin as a positive control. The antibacterial activity results showed that EPUE has antibacterial activity against Staphylococcus aureus with diameter inhibition zone of 8.66±0.57 mm, while ERHPUE and their cream have no activity against Staphylococcus aureus.
Kosmetik hijau adalah kosmetik yang terbuat dari bahan alami, tanpa pewarna atau pengawet buatan, dan lebih ramah lingkungan. Konsumen yang sadar kesehatan akan memilih produk kosmetik hijau karena tidak mengandung bahan yang dapat membahayakan tubuh. Mikroorganisme yang berpotensi untuk dijadikan bahan kosmetik hijau adalah jamur endofit. Jamur endofit adalah mikroorganisme yang hidup di dalam jaringan tanaman, seperti bunga, akar, daun, batang, hingga biji. Jamur endofit tidak membahayakan atau merugikan tanaman inangnya. Jamur endofit merupakan sumber potensial senyawa metabolit. Kajian ini disusun berdasarkan studi literatur jurnal nasional dan internasional menggunakan basis data Google Scholar, Science Direct, dan PubMed yang kemudian dipilah sesuai kriteria inklusi dan eksklusi. Jamur endofit dari tanaman suku Zingiberaceae seperti Zingiber officinale, Kaempferia galanga, Curcuma longa, dan Curcuma xanthorrhiza menunjukkan aktivitas antibakteri terhadap strain bakteri Staphylococcus aureus. Diameter zona hambat jamur endofit tanaman tersebut berada pada rentang 8-32 mm. Selain itu, pada jamur endofit dari tanaman suku Zingiberaceae juga terdapat aktivitas antioksidan. Berbagai hasil studi tersebut menunjukkan jamur endofit dari tanaman rimpang berpeluang dikembangkan lebih lanjut sebagai bahan baku produk kosmetik, khususnya untuk produk anti jerawat dan juga anti-aging. Penelitian lebih lanjut untuk menemukan senyawa bioaktif dari jamur endofit tanaman suku Zingiberaceae perlu dilakukan untuk ekplorasi mikroorganisme dalam sebagai sumber bahan baku produk kosmetik hijau.
Pengaruh Konsentrasi 2,4-Dichlorophenoxyacetic Acid dan Benzyl Amino Purin terhadap Induksi Tunas Tanaman Nilam (Pogostemon cablin Benth.) Varietas Tapak Tuan secara In Vitro Abstrak. Nilam merupakan tumbuhan penghasil minyak atsiri potensial yang menyuplai 90 % kebutuhan minyak nilam dunia. Faktor-faktor yang menyebabkan rendahnya produktivitas nilam antara lain: mutu genetik tanaman, kurang tepatnya budidaya, pengendalian penyakit, pengelolaan panen dan pascapanen. Produksi nilam dapat ditingkatkan dengan teknik propagasi secara in vitro. Eksplan yang digunakan adalah tunas nilam varietas Tapak Tuan. Penelitian bertujuan untuk memperoleh konsentrasi 2,4-Dichlorophenoxyacetic acid (2,4-D) dan Benzyl Amino Purin (BAP) yang optimal untuk induksi tunas nilam (Pogostemon cablin Benth.) varietas Tapak Tuan secara in vitro yang dilaksanakan pada bulan Desember 2021-Mei 2022 di Laboratorium Kultur Jaringan Tanaman, Fakultas Pertanian, Universitas Syiah Kuala, Banda Aceh. Parameter yang diteliti adalah persentase hidup eksplan, persentase tumbuh tunas adventif, dan persentase muncul kalus. Hasil penelitian menunjukkan bahwa persentase hidup eksplan dan persentase muncul kalus terbaik sebesar 100 % terdapat pada 0,5 mg L-1 2,4-D + 0,5 mg L-1 BAP dan 1,5 mg L-1 2,4-D +1,5 mg L-1 BAP. Persentase tumbuh tunas adventif terbaik sebesar 66,67 % dijumpai pada 1 mg L-1 BAP. The Effect of 2,4-Dichlorophenoxyacetic acid and Benzyl Amino Purin Concentration on Shoot Induction of Patchouli (Pogostemon cablin Benth.) variety of Tapak Tuan In Vitro Abstract. Patchouli is a potential essential oil-producing plant that supplies 90% of the world's patchouli oil needs. Factors that cause low patchouli productivity include: genetic quality of the plant, less precise cultivation, disease control, harvest and post-harvest management. Patchouli production can be increased by in vitro propagation techniques. The explants used were patchouli shoots of the Tapak Tuan variety. Research aimed to obtain optimal concentrations of 2,4-Dichlorophenoxyacetic acid (2,4-D) and Benzyl Amino Purine (BAP) for the induction of patchouli shoots (Pogostemon cablin Benth.) of the Tapak Tuan variety in vitro, conducted at December-May 2022 on Plant Tissue Culture Laboratory, Faculty of Agriculture, Syiah Kuala University, Banda Aceh. The parameters studied were the percentage of explant survival, the percentage of adventitious shoot growth, and the percentage of callus emergence. The results showed that the percentage of surviving explants and the percentage of the best callus appearing 100% were found at 0.5 mg L-1 2,4-D + 0.5 mg L-1 BAP and 1.5 mg L-1 2.4 -D +1.5 mg L-1 BAP. The best growth percentage of adventitious shoots was 66.67% found at 1 mg L-1 BAP.
