Abstract

Situ Sipatahunan serves as a source of irrigation, a tourist attraction, and a provider of domestic drinking water, making it important to the community of Baleendah. Monitoring water quality is necessary to detect potential pollution and ensure its suitability in supporting these functions. Phytoplankton is used as a bioindicator because it is sensitive to environmental changes. This study aims to assess the water quality of Situ Sipatahunan based on the phytoplankton community and its relationship with the physical and chemical parameters of the water. Sampling was carried out at three stations using purposive sampling based on different environmental conditions, using a 400 µm plankton net. 25. Data analysis used abundance, diversity, evenness, dominance, saprobic indices, and correlation tests. The results showed that there were 44 phytoplankton species in the waters of Situ Sipatahunan, consisting of the classes Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, Xanthophyceae, Euglenophyceae, and Rhodophyceae. Abundance ranged from 855 to 1096 cells/L/L. Diversity levels were moderate (1.79–1.94), evenness was moderate (0.60–0.69), and dominance was low (0.22–0.29). There is a significant relationship between nitrate and phosphate levels and the level of phytoplankton diversity. Water quality is classified as β–Meso/oligosaprobic or lightly polluted.

Abstract

Seed plants (Spermatophyta) are a group of plants with a very high level of diversity and are widely distributed throughout the world. This group of plants is known as higher plants or Phanerogamae, namely plants that have seeds and reproduce sexually. Spermatophyta can be divided into two main groups, namely Gymnospermae or plants that have characteristics of open seeds and Angiospermae or plants that have characteristics of closed seeds. Research on the structure of internal reproductive organs of seed plants was carried out at the Instructional Laboratory 1 on Campus I UIN SGD Bandung, Cipadung Village, Cibiru District, Bandung City, West Java Province. Qualitative methods were used in this study by conducting direct observations on the objects being observed. This study aims to see and observe how the reproductive structure is in seed plants. Based on data from observations made on paper flowers (Bougainvillea), the flower has no petals, 3 crowns attached to 27 stamens, and 4 pistils with the flower formula K0 [C3 A27] G4. Meanwhile, in the study of lilies (Crinum jagus) have 5 petals, 6 crowns attached to 6 stamens, and 1 pistil with a flower formula of K5 [C6 A6 ] G1.

Abstract

Seed plants or spermatophytes are divided into two, namely angiosperms (open seed plants) and gymnosperms (closed seed plants). These seeds are a means of generative development of spermatophytes. This research aims to observe the internal structure of the reproductive organs of seed plants and observe the phases of embryo development in seed plants.  The method used is observing the structure of internal plant organs and is supported by literature studies related to the research carried out. The objects of this research are lilies (Hippeastrum sp.), pine (Pinus merkusii), and preserved corn (Zea mays).

Abstract

This study aims to test the viability and growth of mung bean (Vigna radiata) sprouts for 11 days. Mung beans were chosen as the object of research because of the ease of the germination process and high nutritional value. The methods used include preparing germination media with moistened opaque paper, as well as observing the parameters of normal, abnormal, and dead seeds. The results showed that in the first repetition, the number of normal sprouts reached 17 seeds with a germination power of 68%, while in the second repetition there were only 11 normal seeds. This study indicates that environmental conditions and proper treatment greatly affect seed viability. Thus, it is important to maintain optimal conditions to increase germination and plant growth results.
