Studi Etnobiologi dalam Makanan Tradisional Garang Asem di Desa Dimoro Kabupaten Grobogan Jawa Tengah

2024-03-31T10:48:29+00:00

Traditional food is local wisdom passed down from generation to generation, including ayam garang asem (a type of chicken curry with a very prominent sour taste). The aim of this research is the diversity of plants used to make garang asem and the process of making it. The research method uses an ethnobotanical approach through surveys and semi-structured interviews. Data was analyzed qualitatively. Ayam garang asem is one of the traditional Javanese ethnic foods in Gumuro village with the main flavors being spicy (garang) and tamarind (asem). The taste of tamarind chicken comes from the plants used, namely spicy (chili) and tamarind (starfruit). It was found that 11 species (12 local name) belonging 8 families and 10 genera of plants were used as ingredients to prepare tamarind chicken. Plants are dominated by the Solanaceae family (4 species), followed by Liliaceae (2 species), the rest are one species for each family. The use of starfruit and bay leaves has great potential to be developed as cooking spices because they have antimicrobial bioactivity so they have great potential to be developed as natural food preservatives.

The purpose of this study was to analyze the composition of floor vegetation in the Fatunisuan Limited Production Forest Area (HPT), North Central Timor Regency. The study was conducted in July – September 2022. The method used is the plot method of 20 plots with sizes of 5 m x 5 m (bush), 2 m x 2 m (herbs), and 1 m x 1 m (shrubs). The results showed that the composition of the vegetation obtained was 22 species consisting of 7 species of shrubs, 9 species of herbs, and 6 species of shrubs. The Important Value Index (INP) was dominated by the shrub level of Chromolaena odorata L. (53.39%.), the herb Hedysarm triquetrum (50.52%), and shrub Mimosa pudica L. (61.72%). Environmental factors also play a role in the presence of floor vegetation such as soil pH with an average of 6.45, soil moisture with an average of 34.97%, air humidity with an average of 61.66%, and air temperature of 41.01ºC. The benefits of this study are to increase the knowledge of researchers about the composition, diversity and potential of floor plants, and obtain information about the diversity of plant species in the floor vegetation group.

2024-03-31T10:48:31+00:00

This research aims to overcome the problem of agricultural waste, the lack of fertilizer which is really needed by agricultural groups by utilizing agricultural waste into Biosaka fertilizer which can be used sustainably for agriculture. This research is expected to increase the growth and productivity of farmers' vegetable crops, namely white mustard (Brassica rapa). This research is a type of quantitative descriptive research with an experimental method using a Completely Randomized Design (CRD). Analysis of research data with Analysis of Variance (ANOVA) calculated using the SPSS program. The growth observed was plant height and number of leaves as well as the wet weight of white mustard plant products. Based on data from research that has been carried out, data was obtained that the P4 treatment, namely giving 80% biosaka to white mustard plants, showed the best results compared to other treatments. The conclusion obtained is that there is an effect of giving Biosaka on the growth and productivity of white mustard plants (Brassica rapa).
