Abstract

Research on the Morphological Diversity of Lansium domesticum Corr in South Sumatra aims to examine the morphological diversity of L. domesticum in South Sumatra. The research was conducted in April 2017 to June 2017. This research was conducted by means of exploration carried out in seven districts covering, East Ogan Komering Ulu District, South Ogan Komering Ulu District, Ogan Komering Ulu District, Musirawas District, Ogan Komering Ilir District, Muara Enim District and Musi Banyuasin District. Sampling was done using purposive sampling method. Observation of morphological diversity was done by characterization of morphology and analyzed by the descriptive method. The result of this research shows that in South Sumatera, there were two variants of L. domesticum namely L. domesticum variant duku and L. domesticum variant langsat. Morphological characters that distinguish between duku and langsat variants were found under canopy conditions, the presence of hair on top and bottom surfaces of leaves, fruit shape, fruit skin thickness, fruit taste, and the presence of sap on ripe fruit.

Abstract

The study aims to determine the diversity of vegetation in the Green Open Space of the Gasing Industrial Area. The study was conducted from April to July 2017. The method of analysis used quadratic method with 2 plots at different location with three repetitions, quantitative data analysis was done on density value, dominance, frequency, important value and diversity index of each plant species. The results showed that vegetation consists of 16 tribes and 19 species, dominated by Pteridophyta and Spermatophyta. Value of vegetation diversity (2,24) and uniformity value 0,30. The higher number of the species, the higher diversity index of the species. Such characteristics are caused by environmental influences such as organic matter content and low pH and factors derived from human intervention. Keywords: Vegetation, Diversity, industrial area

Halimi ES, Negara ZP, Siringoringo VVB. 2022. Growth and productivity water spinach and potential  to  produce seeds  at  suboptimal land. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 178-188. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Water spinach (Ipomea reptans Poir.) is a very popular vegetable crop in Indonesia mostly cultivated by the famers at sub-optimal-dry land. Research was carried out at Expermental Station Faculty of Agriculture, Universitas Sriwijaya in August 2020-April 2021. The obyectives were to identify superior variety in growth, productivity, and potency to produce their seeds for next period of planting. Research was designed as a Randomized Block Design (RBD) with 3 blocks and 3 varieties of Bangkok, Bisi, and Hapsari planted in 40 cm x 20 cm. Plant samples were taken separately for vegetable and for seed production. Research indicated that Hapsari variety showed better growth, higher yield, and performed better appearance, freshness, scent, and flavor valued by the local respondens.  Furthermore, this research revealed that seed production by the farmer could possibly made by maintaining 11-16 plants that were not harvested for fresh-vegetable product.  At about 180 days after planting, those plants were flowering and able to produce about 16.8-25 g seeds per plant or totally about 957-988 seeds that approximately enough for about  100 m2 cultivation area.
