The objective of research was to identify potential plants in order to be utilized as medicinal plant in the yard by community at Cimenteng village in Ujung Kulon National Park Area. Survey and interview method has been carried out with quantitative and qualitative approach. Data was collected by using explorative survey with interview and direct observation in fieldl; and analyzed descriptively. The result indicated that 48 plants have been identified and shown medicinal property; among them 20 plants cultivated in yard and 28 plants grown wildly around the yard. If the plants managed well, then Cimenteng village has an opportunity to be developed as agrotourism village. More than 30 medicinal plants area can be developed as tourism object which is economically will give a benefit for the community.
Beneng taro (Xanthasoma undipes K.koch) is a local wild taro which grows spreading the land area of Gunung Karang in Pandeglang District, Banten Province. Recently, the demand of Beneng taro tubers is increasing due to improvements in its utilization as a food crops. Therefore, Beneng taro is now being cultivated widely by the farmers. However, the use of Beneng taro is still focus on its tubers, while its leaves has not been utilized and only become an agricultural waste. The aim of research was to find out the chemical content of cultivated Beneng taro leaves as a raw material for biopesticide. The research was conducted from July to September 2018. The leaves sample of cultivated Beneng taro were taken from farmer’s field in Juhut Village, Karangtanjung Sub-district. Phytochemical analysis was accomplished in the laboratory. Further, chemical content in the form of alkaloids, flavonoids, saponins, tannins, and oxalic acid were observed. The research result showed that there were negative content for alkaloids, flavonoids, saponins in Beneng taro leaves. The cultivated Beneng taro leaves positively containing tannins, and oxalic acid as much as 3448.20 and 8361.52 mg/kg, respectively. The chemical content of tannins in Beneng taro leaves indicated the potential use of Beneng taro as a raw material for biopesticide.
AbstrakPermasalahan pengembangan tanaman vanili antara lain adalah jarak lokasi pengembangan dengan lokasi sumber bibit cukup jauh serta terbatasnya informasi tentang teknologi perbenihan vanili, terutama teknik penyimpanan bibit untuk pengiriman jarak jauh. Penelitian bertujuan untuk mengetahui media simpan dan lama periode simpan setek berakar yang tepat terhadap mutu bibit vanili. Penelitian dilaksanakan di Rumah Kaca Unit Pengelola Benih Sumber dan Laboratorium Perbenihan Balai Penelitian Tanaman Rempah dan Obat (BALITTRO), Bogor, pada bulan November 2019 sampai dengan bulan Februari 2020. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan jenis media simpan dan periode simpan sebagai perlakuan yang diulang tiga kali. Hasil penelitian menunjukkan bahwa: media simpan cocopeat dan kertas koran mampu mempertahankan mutu fisik: kadar air bibit (>92%) dan kehijauan daun (>28); mutu fisiologis: persentase daya tumbuh (>97%) dan pertumbuhan bibit vanili tetap tinggi sampai 10 hari penyimpanan. Periode simpan 10 hari masih mampu mempertahankan: kadar air (93,83%), kandungan klorofil (28,03) dan daya tumbuh (96,67%) bibit vanili tetap tinggi. Pada periode simpan 8 hari terjadi penurunan laju pertumbuhan (panjang tunas, jumlah daun, diameter tunas, jumlah ruas), namun penurunan pertumbuhan tidak bersifat permanen, karena mulai terjadi pemulihan yang mulai terlihat pada peubah panjang ruas pada minggu ke-8.Kata Kunci: cocopeat, daya tumbuh, kertas koran, kesegaran bibit setek, Vanilla planifolia
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
