Abstract

Environtmental conditions in which plants grow are always changing which when exceeding the tolerance limit will result in stress. Water and light stress affect the pigment content of photosynthesis such as chlorophyll and carotenoids. Dendrobium crumenatum is one of orchid species that is judged to be resistant to various types of environtmental conditions, so it can grow well in any environtment. This research aims to determine the comparison of chlorophyll and carotenoid levels of D. crumenatum from Bantul lowland population, Special Region of Yogyakarta which is given water and light stress treatment. The methods used are extraction with alcohol solvent (96%) and absorbtion level measurements with spectrophotometry at wavelengths 470, 645, and 663 nm. The highest chlorophyll a level contained in the leaves of D. crumenatum which is given water stress treatment, highest chlorophyll b level in control plant, highest total chlorophyll in the leaves which is given water stress treatment, and highest carotenoid level found in the leaves which is given light stress treatment.

Abstract

Kunir asem is one of the traditional drinks that still survive in Javanese society. The young generation needs to be introduced to the heritage of traditional herbal medicine, so that its existence is maintained. Some people judge that herbal medicine is an ancient traditional drink and does not keep up with the times. The objectives of this study are: (1) Explain the study of etnobotany which make up turmeric acid; (2) Explain how the principle of the benefits of kunir asem is based on the understanding of the seller of herbs in the Province of Yogyakarta. This study uses a qualitative method. The research data was taken with documentation, interviews, and documentation. The research data were analyzed by qualitative descriptive. The conclusion of this study is that biopharmaca plants in kunir asem are turmeric and tamarind, and some are added spices in the form of brown sugar, lemongrass, cardamom, cloves, kedawung, lime, and cinnamon. Herb sellers reveal that kunir asem can promote haids, facilitate digestion, reduce stomach acid, as an antibiotic, fresh body, and eliminate acne.

Abstract

AbstrakEkowisata Ayunan Langit memiliki kondisi geografis yang mendukung bagi pertumbuhan anggrek, sehingga daerah tersebut memiliki diversitas anggrek alam yang tinggi sebagai salah satu daya tarik wisata. Beberapa spesies anggrek dapat memiliki kemiripan secara morfologi meskipun tidak berkerabat dekat. Dalam rangka pengembangan Kawasan Wisata Terpadu Ayunan Langit diperlukan data keragaman spesies-spesies anggrek di kawasan ini. Penelitian ini bertujuan untuk melakukan inventarisasi, identifikasi, dan melihat hubungan kekerabatan antar spesies anggrek alam di Kawasan Ayunan Langit. Metode yang digunakan dalam penelitian ini adalah koleksi spesimen, identifikasi, dan karakterisasi morfologi organ vegetatif spesimen, serta analisis hubungan kekerabatan. Analisis kekerabatan menggunakan software Ms Excel dan MVSP. Terdapat 14 spesies anggrek alam yang ditemukan di Kawasan Ayunan Langit. Anggrek alam di kawasan tersebut didominasi dari anggota Subfamili Epidendroideae dan anggrek epifit. Semua spesies masuk dalam kategori Appendix II CITES. Berdasarkan analisis kekerabatan fenetik, dendogram terbagi dalam dua kluster berdasarkan karakter morfologi organ vegetatifnya. Spesies anggrek yang berasal dari genus yang sama belum tentu dapat mengelompok pada klaster yang sama, misalnya pada Dendrobium. Karakter morfologi organ vegetatif belum dapat digunakan untuk melihat hubungan kekerabatan fenetik secara akurat pada anggrek. Karakter organ generatif berperan penting dalam memberikan hasil visualisasi kekerabatan antar spesies anggrek yang lebih akurat.AbstractAyunan Langit ecotourism has favorable geographical conditions for orchid growth, hence the area has a high diversity of wild orchids as a tourist attraction. Several orchid species can be morphologically similar even though they are not closely related. For Ayunan Langit integrated tourism area development, orchid diversity data are required. This study aimed to conduct an inventory, identification, and relationship analysis between wild orchid species in Ayunan Langit ecotourism. Specimen collection, identification, and morphological characterization were conducted on specimen's vegetative organs. Relationship analysis was conducted with Ms Excel and MVSP. There are 14 wild orchid species found in the Ayunan Langit, dominated by Epidendroideae members and epiphytic orchids. All species are included in the CITES Appendix II category. Based on the phenetic relationship analysis, the dendrogram was divided into two clusters based on the morphological characters of the vegetative organs. Orchid species belongs to the same genus may not necessarily be grouped in the same cluster, for example in Dendrobium. Morphological characters of vegetative organs cannot be used to visualize the phenetic relationship accurately in orchids. Generative organ characters play an important role in providing a more accurate visualization of the relationship between orchid species.

Abstract

Konservasi anggrek alam diperlukan melihat semakin menurunnya keanekaragaman spesies di bumi akibat aktivitas manusia dan degradasi lingkungan. Dengan mengetahui pola distribusi dan kemelimpahan dari spesies anggrek alam dapat membantu dalam upaya konservasi. Hutan Wanagama merupakan hutan buatan yang bersifat kering, tandus dengan topografi berupa batuan gamping dan kandungan air yang minimal. Selain dijumpai 100 flora di Hutan Wanagama, spesies anggrek alam juga dapat dijumpai pada wilayah tersebut. Penelitian ini bertujuan untuk mengetahui distribusi, kemelimpahan dan strategi konservasi yang dapat diterapkan bagi anggrek epifit yang ada di Hutan wanagama. Metode yang digunakan adalah metode plotless. Jalur yang dilewati direkam menggunakan GPS Esensial dan divisualisasi dengan Google Earth Pro. Berdsarkan hasil inventarisasi ditemukan empat spesies anggrek epifit yaitu Rhynchostylis retusa, Aerides odorata, Dendrobium crumenatum, dan Dendrobium secundum dengan pola persebaran mengelompok (clump). R. retusa merupakan anggrek epifit dengan kemelimpahan tertinggi. Kemelimpahan dan distribusi anggrek epifit dipengaruhi oleh kondisi iklim mikro, ketinggian, tipe habitat, persebaran biji dan tipe reproduksi vegetatif. Strategi konservasi yang dapat diterapkan di Hutan Wanagama yaitu penerapan ekowisata berbasis edukasi konservasi anggrek alam dan konservasi in situ.
