Background: Covid-19, caused by a new type of coronavirus named SARS-CoV-2, has become a pandemic. Together with SARS-CoV and MERS-CoV, Covid-19 is a large global outbreak of coronavirus infection; however, its rate of spread is much higher. Since the vaccines and anti-SARS-CoV-2 have not been found, a faster control mechanism is needed. Traditional herbs have shown the potential for this purpose, as has been demonstrated by the Chinese Government with a high success rate. One of the herbs used was Lindera aggregata, which is part of the collection in Purwodadi Botanic Garden. Objectives: Through in silico study, this research aims to reveal the secondary metabolites contained in L. aggregata that have the potential to serve as anti-SARS-CoV-2 medication as well as showcase their inhibitory mechanisms. Methods: The research was conducted through molecular docking analysis of terpenoids and alkaloids contained in the root of L. aggregata, with target proteins 3CLpro, PLpro, Spike, and ACE 2 playing a role in SARS-CoV-2 infection. Result: All analyzed compounds tended to interact with all four target proteins with different binding affinity values, but the interaction seemed stronger with 3CLpro and Spike. Terpenoids, linderane and linderalactone, had the strongest interaction tendency with 3CLpro, PLpro, and Spike; the compound norboldine, an alkaloid, had the strongest interaction with ACE 2, with a binding affinity value of -8.2 kcal/mol. Conclusion: Terpenoids and alkaloids contained in the root of L. aggregata, which caused inhibition of adsorption and replication of SARS-CoV-2, could serve as anti-SARS-CoV-2.

Purwodadi Botanic Garden (KR Purwodadi) is an ex situ conservation institution for dry climate lowland plants aiming at saving and protecting biodiversity from extinction. In supporting ex situ conservation efforts, plant exploration activities in their natural habitat need to be carried out. Alas Purwo National Park has a lowland forest area with abundant plant diversity. In addition to functioning as a conservation forest, this area is also a natural and religious tourist attraction, so it is likely to undergo ecosystem damage. Therefore, this plant diversity study with the activity of plants exploration and collection was carried out for the purpose of ex situ conservation in KR Purwodadi. This study was conducted in August to September 2019 using an explorative method. A total of 24 species were obtained, of which 8 species were not yet cultivated by KR Purwodadi. Besides, there were 5 species included in the IUCN red list, namely Aglaonema simplex, Brucea javanica, Cycas rumphii, Melanolepis multiglandulosa, and Musa acuminata. This study has increased the number of plant collections in KR Purwodadi and contribute positively to the comprehensiveness of plant species data in Alas Purwo National Park.

<p>Tumbuhan telah dikenal sebagai sumber obat alami yang dapat menyembuhkan berbagai macam penyakit karena mengandung senyawa metabolit sekunder dengan aktivitas biomedik. Tumbuhan paku merupakan kelompok tumbuhan tertua di bumi yang memiliki lebih dari 12.000 jenis. Tumbuhan paku mengandung senyawa metabolit sekunder yang berpotensi obat berdasarkan<br />studi etnobotani dan farmakologi. Sebanyak 20 suku dan 38 marga tumbuhan paku dikoleksi dan dikonservasi secara ex situ oleh Kebun Raya (KR) Purwodadi. Nephrolepis merupakan salah satu marga dari koleksi tumbuhan paku KR Purwodadi dengan jumlah spesimen paling banyak. Nephrolepis termasuk kelompok tumbuhan paku epifit atau setengah epifit yang daunnya tersusun<br />menyirip tunggal seperti pedang. Selama ini Nephrolepis hanya dikenal sebagai bahan sayuran dan tanaman hias oleh masyarakat. Namun belum ada informasi mengenai potensi obat dari koleksi Nephrolepis tersebut. Oleh karena itu, penelitian ini dilakukan untuk menginventarisasi dan mengarakterisasi potensi koleksi Nephrolepis di KR Purwodadi sebagai tanaman obat. Metode yang<br />digunakan pada penelitian ini adalah inventarisasi data dari Sistem Informasi Katalog Koleksi Tanaman (SIKATAN), pengamatan langsung di rumah kaca, dan studi etnomedisin dan fitokimia berdasarkan literatur. Berdasarkan hasil inventarisasi, telah diperoleh 36 spesimen yang termasuk dalam 6 jenis Nephrolepis. Spesimen tersebut memiliki potensi mengobati berbagai macam penyakit, baik yang telah dikenal dalam pengobatan tradisional maupun dari hasil penelitian. Koleksi Nephrolepis tersebut mengandung berbagai senyawa, seperti alkaloid, flavonoid, dan terpenoid yang memiliki aktivitas farmakologi, di antaranya antioksidan, antiinflamasi, antimikroba, antivirus, dan antikanker. Di samping itu, jenis N. cordifolia merupakan koleksi yang paling potensial<br />sebagai obat karena bagian daun, rimpang, hingga umbinya memiliki aktivitas antiinflamasi, antimikroba, antikanker, antimalaria, dan antioksidan.</p>

Purwodadi Botanical Garden is a botanical garden that specifically designated to ex situ plant conservation with typical habitats of low lands and dry areas. In an effort to protect and maintain the collection of plants, one of the things that must be carried out is the monitoring of plant pests and diseases. The research aimed to find out the plant pests and diseases that infect in plant collections at Vak I-V in Purwodadi Botanical Gardens. The method used was a descriptive observation and literature study, while the secondary data were books and environmental maps. There were nine types of pests and nine types of diseases. Pests and diseases are dominated by Leaf Spot Disease, Black Ants, Red Ants, and Lawana candida. They attack some plants, such as from family of Sapotaceae, Sterculiaceae, Mimosaceae, Moraceae, etc. The results of this study can be used as a material consideration in efforts to prevent and increase ex-situ conservation in the Purwodadi Botanical Garden.
