Abstract

Hydrophyte merupakan penggambaran habitat dari tumbuhan yang hidup di air baik terendam sebagian atau seluruhnya. Indonesia memiliki kekayaan jenis hydrophyte yang sangat tinggi, namun penelitian terkait inventarisasi belum dilakukan secara menyeluruh. Tujuan penelitian ini adalah untuk mengetahui kekayaan jenis hydrophyte air tawar yang ada di Sumatera Barat dan dikelompokkan berdasarkan life-form. Penelitian ini telah dilaksanakan pada November 2020 hingga Maret 2021. Metode yang digunakan adalah observasi dan data diperoleh menggunakan metode herbarium. Semua informasi pada label spesimen (occurence, taxon information dan event) diamati dan dicatat. Dari penelitian ini didapatkan 78 spesies dengan 54 genus dari 28 famili hydrophyte di Herbarium ANDA. Sebanyak 11 famili merupakan kelas Liliopsida dan 17 famili kelas Magnoliopsida. Berdasarkan life-form 2 jenis merupakan free-floating, 4 jenis floating-leaves, 7 jenis submersed dan 65 jenis lainnya merupakan emergent. Informasi penting secara konservasi pada penelitian yaitu ditemukan 4 spesies endemik dan 2 spesies new occurence. Tiga spesies endemik Sumatera, yaitu Apoballis okadae, Furtadoa sumatrensis (Araceae) dan Potamogeton sumatranus (Potamogetonaceae). Satu spesies endemik Sumatera Barat, yaitu Homalomena rusdii (Araceae). Taksa new occurence, Eleocharis acicularis (Cyperaceae) sebelumnya di Indonesia hanya ditemukan di Sumatera Utara, pada penelitian ini ditemukan di Sumatera Barat, Kabupaten Lima Puluh Kota. Heteranthera reniformis (Pontederiaceae) sebelumnya di Indonesia hanya ditemukan di Bogor, Jawa Barat, pada penelitian ini ditemukan di Kabupaten Tanah Datar, Sumatera Barat.

Abstract

Homalomena is a genus from the family Aracaceae that is characterized by scent. Most Homalomena species from Indonesia have limited information on the chemical components of their essential oils, including those found in West Sumatra Province. The species of Homalomena aff. pendula (Blume) Bakh. F. is found in large amounts in Padang city, and it has the potential to explore its profile of essential oil substances in its leaves, petioles, and rhizomes. In this research, the antioxidant activity of the essential oils was screened using three methods: DPPH, ABTS, and FRAP. The essential oils are extracted through hydro-distillation, and their components are analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). The results show that the three major components in the leaves and petioles were β-bisabolene, α-selinene, and α-bergamotene with different percentages. The rhizomes had the same higher component as β-bisabolene, followed by trans-caryophyllene and α-bergamotene. The antioxidant activity, as measured by DPPH and ABTS, showed an IC50 greater than 200 μg/mL. That result is also supported by the FRAP value of leaves, petioles, and rhizomes, 0.165±0.0081;  0.168±0.0019;  0.191±0.0003 µmol Fe(II)/mg sample and 0.013±0.0006; 0.014±0.0001; 0.015±0.0001 µmol trolox/mg sample, respectively. Although the essential oils from H. aff. pendula do not exhibit antioxidant activity, the primary compound, β-bisabolene, has been shown to possess other potential activities.

Abstract

Kearifan lokal adalah pengetahuan dan pandangan hidup yang diwujudkan dalam bentuk kegiatan yang dilakukan oleh masyarakat setempat dalam memenuhi kebutuhan hidup mereka. Adat istiadat dan kebiasaan yang secara turun-temurun telah dilakukan oleh sekelompok orang selama beberapa generasi dan masih dipertahankan oleh komunitas-komunitas yang menganut hukum adat di wilayah-wilayah tertentu. Pandangan hidup masyarakat tersebut tercermin dalam pemanfaatan keanekaragaman hayati lokal yang tetap menjaga keberlanjutannya. Keanekaragaman hayati meningkatkan ketahanan sistem alam, sedangkan keanekaragaman budaya memiliki kemampuan untuk meningkatkan ketahanan sistem sosial. Penelitian ini bertujuan untuk menganalisis pola kearifan lokal dalam pengelolaan keanekaragaman hayati lokal di Talago Gunung Sawahlunto. Penelitian ini dilakukan di Kecamatan Talago Gunuang, Kota Sawahlunto, dari bulan Juli hingga Oktober 2022. Metode penelitian ini adalah penelitian survei dengan pengumpulan data lapangan berupa observasi, wawancara mendalam, dan wawancara mendalam. Analisis data dilakukan melalui reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa dalam pemanfaatan keanekaragaman hayati di Nagari Talago Gunuang, terlihat masyarakat memanfaatkan tanaman lokal sebagai tanaman obat, bahan masakan, serta buah-buahan lokal untuk dikonsumsi. Beberapa tanaman obat menjadi bagian dari nilai tradisi dan budaya lokal dalam menyembuhkan berbagai penyakit serta memiliki nilai filosofis. Hutan bagi masyarakat merupakan tempat tumbuhnya tanaman lokal yang dapat dimanfaatkan sebagai lahan pertanian dan sumber kayu, namun terdapat pula hutan terlarang yang tidak boleh dimanfaatkan oleh masyarakat. Oleh karena itu, nilai-nilai kearifan lokal sangat erat kaitannya dengan perlindungan keanekaragaman hayati lokal di Nagari Talago Gunuang, Kota Sawahlunto.Kata kunci: kearifan lokal, konservasi, keanekaragaman hayati, masyarakat adat, Nagari Talago Gunuang.

Abstract

Studi mikromorfologi polen dan analisis numerik karakter morfologi telah dilakukan terhadap lima taksa Plagiostachys yang terdistribusi di Sumatra. Observasi mikromorfologi polen dilakukan menggunakan mikroskop cahaya (Light Microscope/LM) dan mikroskop elektron pemindai (Scanning Electron Microscope/SEM). Pengelompokan taksa dilakukan secara numerik menggunakan analisis UPGMA berdasarkan 16 karakter makromorfologi dan mikromorfologi. Butir polen yang diamati tergolong tipe monad, berbentuk prolate-sphaeroidal, tidak memiliki apertur (inaperturate), berukuran sedang (medium), dengan tipe ornamentasi dinding polen micro-rugulate, psilate, dan echinate-reticulate. Ornamentasi berduri (echinate) ditemukan pada sebagian besar spesies Plagiostachys, dan pada tingkat spesies, karakter ini memberikan evidensi tambahan yang signifikan untuk membedakan P. roseiflora dan P. crocydocalyx. Analisis numerik menghasilkan dua kelompok utama, dengan P. crocydocalyx dan P. roseiflora pada kelompok A, dan kelompok B terbagi menjadi 2 subkelompok: subkelompok I terdiri dari seluruh individu P. mucida dan Plagiostachys sp. sedangkan subkelompok II terdiri dari seluruh individu P. sumatrensis. Sebagai kesimpulan, karakter mikromorfologi polen memberikan kontribusi secara sistematis untuk memperkuat klasifikasi genus Plagiostachys.

Abstract. Pitopang R, Umrah, Harso W, Nurainas, Zubair MS. 2020. Some botanical aspects and antifungal activity of Etlingera flexuosa (Zingiberaceae) from Central Sulawesi, Indonesia. Biodiversitas 21: 3547-3553. Etlingera flexuosa is a species of Etlingera endemic to the island of Sulawesi and its natural distribution is restricted to Central and South Sulawesi, where it has been utilized for different purposes. Despite the limited knowledge in the aspects of botany and its antimicrobial activities, the use of plants as a source of alternative solutions to health problems is on the rise. The objectives of this study were to obtain some information about the several botanical aspects of E. flexuosa and its antifungal activity. This research was conducted from March to December 2019 and samples were collected from the montane forest of Lore Lindu National Park (LLNP) near Sedoa Village, Lore Utara Sub-district, Poso District, Indonesia. The identification of plant specimens and extractions was carried out at the Laboratory of Plant Biosystematics, Tadulako University, Palu, Indonesia. The antifungal activity was tested using agar diffusion methods. The results showed that E. flexuosa is a perennial herb naturally distributed in Sulawesi island. It usually grows in the pristine submontane and montane forests, sometimes in light and open condition or on the slope of natural disturbed forest at the altitude of 1500 -1700 m a.s.l. The forest is dominated by Fagaceae family, of which E. flexuosa has been utilized extensively by local community of Topo Baria ethnic for various purposes such as flavor enhancer in food, vegetable, traditional medicine, and as roofing materials. It contains some secondary metabolites such as flavonoids, tannins, saponins, terpenoids, alkaloids and steroids, and also shows antioxidant activity. Conclusively, the extract of E. flexuosa could be used as inhibiting agent for the growth of Candida albicans yeast.

Abstract. Syamsuardi, Nurainas, Taufiq A, Harmawan T, Suwardi AB. 2021. Aneuk Jamee traditional foods in the South Aceh District, Indonesia. Biodiversitas 23: 443-454. The traditional foods of the Aneuk Jamee Tribe have a long history and unique traditions passed down for thousands of years. However, a lack of information about indigenous and traditional foods of the Aneuk Jamee Tribe will lead to a decline in local knowledge of traditional foods, particularly among the younger generation. Therefore, this study aimed to investigate the variety of Aneuk Jamee traditional foods in the South Aceh District of Indonesia. The study was conducted in South Aceh, Indonesia, Labuhan Haji Timur, Kota Bahagia, and Kluet Selatan Sub-districts. The study involved 90 respondents (30 from each sub-district) chosen at random. The interview was conducted using a questionnaire covering the respondents' backgrounds, traditional food names, food composition, mode of preparation, and uses. As a result, 52 Aneuk Jamee's traditional foods were identified from three sub-districts of South Aceh District, including 41 types of traditional cuisine and 11 types of traditional snacks. All respondents recognised Gulai ciik minyak, Gulai taleh, Gulai paku, Gulai cabadak, Gulai kabau, Gulai kambieng, Gulai ikan panjang, Gulai kitang, Kue kakareh, Limpieng sagu, and Limpieng ubi as Aneuk Jamee traditional foods. On the other hand, less than 20% of respondents were familiar with other traditional foods, such as Lamang ubi. The Aneuk Jamee Tribe has an excellent system for passing down traditional knowledge from generation to generation. Fifty-six plant species consisting of 47 genera and 28 families were used as Aneuk Jamee traditional food. The Aneuk Jamee Tribe prepares various foods from various plant species to maintain their health and contribute to household income and conservation efforts.

Abstract. Harapan TS, Nurainas, Syamsuardi, Taufiq A. 2022. Identifying the potential geographic distribution for Castanopsis argentea and Castanopsis tungurrut (Family: Fagaceae) in the Sumatra Conservation Area Network, Indonesia. Biodiversitas 23: 1726-1733. Recently, Castanopsis argentea (Blume) A.DC. and Castanopsis tungurrut (Blume) A.DC. have been listed as endangered species by the International Union for the Conservation of Nature (IUCN). For conservation planning, it is important to know the full distribution of species. This study aimed to predict the potential distribution of C. argentea and C. tungurrut using MaxEnt, and understand key factors responsible for the distribution of these species. A total of 53 occurrences and six environmental variables were used to model their distribution. The AUC values of C. argentea and C. tungurrut were 0.86 and 0.91, respectively, and the models suggest the distribution of both species is mainly influenced by elevation, and temperature seasonality for C. tungurrut. The predicted distributions of the species are in the mountains of the western part of Sumatra, and their range includes 12 conservation areas that have highly suitable habitats for both species. After generating the MaxEnt prediction map, we conducted field validation to validate the model predictions. Field surveys in two predicted areas showed that the predicted distribution maps accurately estimated the distribution of C. argentea and C. tungurrut at those localities.

Abstract. Syamsuardi, Mukhtar E, Nurainas, Suwardi AB. 2022. Diversity and use of wild edible fruits in the Bukit Rimbang - Bukit Baling Wildlife Reserve, Kampar, Riau, Indonesia. Biodiversitas 23: 5035-5042. The Bukit Rimbang-Bukit Baling Wildlife Reserve is a protected area with a diverse ecosystem and vegetation. The area provides many ecosystem services that are critical to life, particularly for humans. The aim of this study is to document wild edible fruits and their use by the community surrounding the Bukit Rimbang-Bukit Baling Wildlife Reserve. The study was carried out in eight villages of Kampar district, Riau province, namely Tanjung Belit, Tanjung Belit Selatan, Gema, Kota Lama, Muara Bio, Muara Selayah, IV Koto Setingkai, and Sungai Rambai. This study was based on field surveys, plant collection, and interviews with the local people. Interviews were performed with 334 respondents selected by using the random sampling technique. A total of 67 wild edible fruit plant species, consisting of 29 families, have been documented in the study area. Artocarpus integer, Mangifera odorata, Mangifera foetida, Nephelium maingayi, Durio oxleyanus, Syzygium polyanthum, Pometia pinnata, Baccaurea deflexa, Garcinia xanthochymus, and Bellucia pentamera were among the plants recognized and frequently harvested by respondents. Local communities use wild edible fruits as food, either eaten raw or processed into candy, snacks, or vegetables. About 54% of the respondents reported traditional knowledge linked to wild edible fruits is transferred from the parents/grandparents to the next generations in the study area. The expansion of agricultural lands and the decline in traditional knowledge are the main threats to the sustainability of wild edible fruits in the study area.

Abstract. Ritonga MA, Syamsuardi, Nurainas, Damayanto IPGP. 2023. Bamboo diversity in Weh Island, Aceh, Indonesia. Biodiversitas 24: 2563-2576. Bamboo is an important plant resource in Indonesia, whose inventories were mostly conducted on the main islands. In contrast, the inventory for small islands, such as Weh Island in Northern Sumatra, has never been done. Weh Island, however, is an atoll island that has been raised above sea level and is suspected to have a unique diversity of flora, especially bamboo. This study aimed to understand the diversity of bamboo on Weh Island. Fieldwork was conducted in August-September 2022 in Weh Island, Aceh, Indonesia. Bamboo specimens were collected by collecting flora diversity method and deposited in Herbarium Andalas and Herbarium Bogoriense. Morphological characteristics were observed to identify and arrange species descriptions and as a determination key. The spatial distribution of bamboo was analyzed using QGIS software and overlaid with a land cover and altitude map. We also performed a similarities analysis using morphological characteristic. There are eight species of bamboo on Weh Island: Bambusa multiplex (Lour.) Raeusch. ex Schult.f., Bambusa spinosa Roxb., Bambusa tuldoides Munro,Bambusa vulgaris Schrad. ex J.C.Wendl., Dendrocalamus asper (Schult.f.) Backer, Schizostachyum brachycladum (Kurz ex Munro) Kurz, Schizostachyum silicatum Widjaja, and Thyrsostachys siamensis Gamble. B. vulgarisis most abundant and widespread on Weh Island; meanwhile, B. multiplexand B. tuldoidesare the least common. The presence of S. silicatum on Weh Island and Bangka Island was additional information on the expansion of these species distributions outside the mainland of Sumatra. Bamboos on Weh Island were found around settlements, plantations, and forests at 1 to 212 m asl. Bamboo species on Weh Island can be clustered into four groups based on their morphological characteristics.
