Silalahi M, Nisyawati. 2018. The ethnobotanical study of edible and medicinal plants in the home garden of Batak Karo sub-ethnic in North Sumatra, Indonesia. Biodiversitas 19: 229-238. The ...cultivation of plants in home gardens for self-sufficiency is a long tradition in Karo District, but the documentation of local knowledge about edible and medicinal plants in home gardens in Karo District is limited. This study aimed to (i) document the uses of the edible and medicinal plants in home gardens; (ii) to analyze the diversity of edible and medicinal plants in home gardens. Data were collected using the ethnobotanical surveys and interviews methods. The Shannon Weiner and Margalef indices were calculated to determine the diversity levels of medicinal and edible species in the home gardens of Karo ethnic. The surveys were conducted in 30 home gardens (7 villages), Karo District, North Sumatra. The 85 recorded species belonged to 43 families, and 73 genera were used as edible and medicinal plants. The plants studied in the home gardens used for human consumption were i.e. fruits, vegetables, spices, tubers and medicinal plants. Among 85 plant species growing in home gardens, 52 species were cultivated, and the rest were semi cultivated. Home gardens had the Shannon Wiener index ranging from 1.164 to 3.123 while Margalef index ranging from 0.929-2.531.
Silalahi M, Khairiah A, Nisyawati. 2020. Ethnomedicinal plants and practices related to pregnancy, childbirth, and postpartum healthcare of Minangkabau ethnic group, West Sumatra, Indonesia. ...Biodiversitas 21: 4597-4605. In the Minangkabau ethnic cultures, medicinal plants have been used to treat health problems associated with pregnancy, childbirth, and postpartum period (PCP). The objectives of this study were to (i) document the medicinal plants used during pregnancy, childbirth, and postpartum recovery by Minangkabau ethnics and the associated ethnomedicinal practices, and (ii) identify plants that have the potential to be developed as ingredients to increase the production of breast milk. Data were collected in three villages, namely Guguak Sarai, Taruang Taruang, and Sungai Durian in West Sumatra, Indonesia, by interviewing a total of 141 informants, involving 9 key informants and 132 general respondents. A total of 42 species of medicinal plants were found to be used for PCP healthcare by Minangkabau people. These medicinal plants are used to facilitate childbirth, alleviate menstruation problems, assist recovery after miscarriage, mitigate postpartum hemorrhage, aid in postpartum recovery, and for infant care. A total of 26 species were represented by 9 families i.e. Poaceae (7 species), Arecaceae, Fabaceae, Zingiberaceae (3 species respectively), Euphorbiaceae, Lamiaceae, Meliaceae, Musaceae, and Asteraceae (2 species each). Majority of the used medicinal preparations are administered by drinking (35 species), bathing (4 species), and as a paste (3 species). Use of Musa balbisiana, Carallia brachiata, Lansium domesticum, and Toona sureni for treating problems related to pregnancy, childbirth, and postpartum period need to be further investigated for their phytochemistry and pharmacological properties. Plectranthus ambonicus and Sauropus androgynus are used to increase breast milk production, and further research is needed for standardizing processing and commercialization of these species.
Silalahi M, Supriatna J, Walujo EB, Nisyawati. 2015. Local knowledge of medicinal plants in sub-ethnic Batak Simalungun of North Sumatra, Indonesia. Biodiversitas 16: 44-54. Research on the local ...knowledge of medicinal plants by sub-ethnic BatakSimalungun of North Sumatra was conducted, using an ethnobotanical approach. The sample consisted of 8 key informants and 32general respondents, who were grouped into two, namely those who were 30-50 years old and >50 years old. Data were analyzed bothqualitatively by descriptive statistics and quantitatively by calculating the index of cultural significance (ICS) and the use value (UVs).It was found that 239 species (170 genera, 70 families) of medicinal plants were used to cure 18 kinds of natural diseases and 2 kinds ofsupra natural diseases. Almost half of those plants (119 species) had leaves used as medicines. Among the diseases, gastrointestinaldisorders had the highest number of medicinal plants used (72 species), followed by fever (64 species), and fractures (41 species). Itseemed that younger generation had lost their knowledge in the medicinal plants because their knowledge of medicinal plants (48.19 ±8.35 species) was lower than the that of older generation (170.19 ± 18.38 species), while our key informants had the highest knowledgeof medicinal plants among respondents (202.00 ± 12.32 species).

Zulkarnaen RN, Nisyawati, Witono JR. 2019. Population study and habitat preferences of Pinang Jawa (Pinanga javana) in Mt. Slamet, Central Java, Indonesia. Biodiversitas 20: 712-718. Conservation ...effort of Pinang Jawa is hampered due to lack of information on its ecology and population biology. The species is an endemic palm species to Java. The study aimed to assess the population study and habitat preference of Pinang Jawa in Mt. Slamet, Central Java. The research design used a purposive sampling method with a plot measuring 10x10 m. The observation plot was successfully made with a total of 183 plots. The result showed that the population was dominated by adult palm (mature) with the number of 1023 individuals on the southern slope of Mt. Slamet. Individuals growth dominated in hill slope. Population structure was dominated by individuals with stem heights of 6.1-8.1 m and stem diameters of 7-8.9 cm. The stem height and stem diameter class distribution showed that high mortality rate occurs in the seedlings stage class, although this stage should be high recruitment due to the seed production is perennial continuously. Predators were identified as the main threat for seedlings of Pinang Jawa. The result of statistical analysis clearly provides reveals that abiotic factors in which influencing the density of Pinang Jawa was slope, litter thickness, and crown cover.

Putrika A, Nabella DM, Salamah A, Nisyawati, Dwiranti A. 2020. Ultrastructure of Lejeunea spp. leaves surface in a lowland tropical urban forest of Universitas Indonesia Campus, Depok, Indonesia. ...Biodiversitas 21: 4184-4191. Lejeunea is one of liverworts genera that have a wide distribution in the world. It has many variations of the character that have not been revealed, such as variations of the cell surface. The purpose of this research was to study the ultrastructure of Lejeunea spp. leaves surface in a lowland tropical urban forest of Universitas Indonesia (UI) Campus, Depok, Indonesia. Six species of Lejeunea spp. were studied, i.e., L. anisophylla, L. cocoes, L. exilis, L. papilionacea, L. catanduana, and L. curviloba. The research methods carried out in this study consisted of the sample observation using a light microscope, sample preparation for Scanning Electron Microscope (SEM) observation (fixation, post-fixation, dehydration, drying, mounting), and observations using SEM. The results of observation using a light microscope showed the smooth cell surface of all samples studied. Meanwhile, the differences between six species of Lejeunea in the UI campus could be differentiated under SEM. L. catanduana could be distinguished from other species from its cell wall thickness and texture, ornamentation types, and the number of ornamentations per cell. The texture of the cell wall of L. catanduana was the roughest than the other species due to abundant ornamentation such as papillae on its the cell wall surface. Furthermore, only this species has mamillae on the cell surface. The number of papillae or mamillae was 1-4 per cell. On the other hand, L. cocoes has the thinnest cell wall and slightly rough texture. Only this species has the simple papillae on the cell surface. Thus, the results of this study suggested that the cell surface variations in Lejeunea might be potential to be used as taxonomic characters in grouping species.
