Abstract

Abiu (Pouteria caimito Radlk.) is a plant of Sapotaceae family that can be consumed fresh, processed, or as a medical product. The fruit and leaves of this plant contain bioactive compounds. This research aims to inform the interaction between leaf:fruit ratio treatment and foliar fertilizer on the quality of the abiu fruit. The study was conducted at Kebun Balungbang Jaya, Dramaga, Bogor, West Java Province, from July 2022 to November 2022. The experiment used a factorial split plot design. The main plot was a leaf:fruit ratio treatment (N1, 45 leaves:1 fruit, and N2, 30 leaves:1 fruit) on each tertiary branch, and the tiller plot was foliar fertilizer (P1: 1 g L-1, P2: 2 g L-1, and P3: 3 g L-1), which consisted of 3 replications. The results showed that treatment of the leaf-fruit ratio and foliar fertilizer did not affect the quality of the abiu fruit. The interaction between leaf:fruit ratio and foliar fertilizer had a significant effect on ATT, as indicated by the lowest acidity value in the leaf:fruit ratio treatment of 45:1 and a fertilizer concentration of 1 g L-1 with a value of 0.12% but has no significant effect on the external and internal quality of other fruits. Keywords: Bioactive compounds, sapotaceae, tertiary branch, titratable acidity

Abstract. Ruwaida IP, Santosa E, Susila AD, Widodo WD, Wachjar A, Nasrullah N. 2022. Perceived biodiversity of fruit species for urban greenery in Indonesia: Case studies in Bogor, Jakarta, and Yogyakarta. Biodiversitas 23: 3166-3177. Urban greenery planning considering biodiversity scenarios is still rarely studied in Indonesia. This study aims to demonstrate edible fruit species (FS) as the scenario for urban greenery based on interviews with citizens in Indonesian cities. The study was carried out in the cities that have implemented smart city models i.e., Bogor, Jakarta, and Yogyakarta-Indonesia. Interviews were conducted in July-December 2019, involving 420 respondents. The results showed that 77.7% of all respondents agreed with the planting of FS as city greenery. In total for all cities, there were 79 species belonging to 32 families mentioned by the respondents consisting of 41 commercial and 38 underutilized FS. Each respondent was able to mention between 20.4 and 22.8 fruit species, irrespective of city. The ability to mention fruit species was affected by the respondent’s background, especially exposure during childhood to FS, frequency as a domestic tourist, mobility mode, and frequency of visiting city parks. The rationale for selecting FS was the benefit of fruit as a food source, followed by the benefit of ecology, economy, aesthetics, and health. Based on the significant cultural index, mango ranked first as the most preferred commercial fruit species, followed by rambutan, rose apple, orange, papaya, starfruit, guava, avocado, sapodilla, and longan; and for underutilized FS were shoe-button, pinang, nam nam, mulberry, cactus, canistel, cherry, and pear. Value of species richness, Shannon-Wienner, and Simpson diversity indices of FS within a city ranged 0.97 to 1.06, 3.62 to 3.83, and 0.97, respectively. Biodiversity scenarios could be useful information in the greenery planning of smart cities to coop with evolving broader environmental services.
