Abstract

Various types of plants are found in Lemor Botanical Garden Forest (located in Suela Village, East Lombok Regency), one of which is epiphytic plants. Epiphytic plant are plants that live attached to other plants. This study aims to determine the types of epiphytic in the Lemor Botanical Garden Forest and the most dominating epiphytic species based on the environmental characteristics of the Lemor Botanical Garden Forest. This research is a descriptive research. Data collection was carried out using the cruisi method from October to November 2024. Data were analyzed qualitatively. The results showed that in the Lemor Botanical Garden Forest, 15 species of epiphytic were found consisting of 8 families and 797 individuals.  The types of epiphytic found include: Grosourdya appendiculata, Nephrolepis exaltata, Microlepia todayensis, Goniophlebium verrucosum, Goniophlebium persicifolium, Drynaria quercifolia, Drynaria sparsisora, Pyrrosia eleagnifolia, Pyrrosia longifolia, Microsorum punctatum, Cryptogonium phyllogonioides, Thuidium glaucinoides, Rhaphidophora pinnata, Syngonium podophyllum, and Piper betle. The most dominating epiphytic species based on the environmental characteristics of Lemor Botanical Garden Forest are epiphytic found growing in the watershed many as 13 species, 3 of which are: Drynaria quercifolia, Microsorum punctatum, and Rhaphidophora pinnata, with a percentage of 37%. The most dominant species found was Drynaria quercifolia from the Polypodiaceae family with 148 individuals.

Abstract

Land kale (Ipomea reptans P.) is a popular leafy vegetable in Indonesia due to its fast growth and high nutritional value. Its productivity relies heavily on the proper application of fertilizer. This study investigates the effects of NPK fertilizer, Bokashi fertilizer, and their combination on land kale's vegetative growth and chlorophyll content. Conducted from May to July 2025 at the Faculty of Agriculture, University of Mataram's greenhouse, the experiment employed a Completely Randomized Design (CRD) with two factors: five levels of NPK fertilizer (0–2 gr/100 ml water) and five levels of Bokashi fertilizer (0–400 gr/polybag). Growth parameters measured included plant height, number of leaves, stem diameter, fresh weight, dry weight, and chlorophyll content. Data analysis involved two-way ANOVA and Duncan’s Multiple Range Test (DMRT). Results indicated NPK fertilizer significantly affected all growth parameters and chlorophyll content, while Bokashi fertilizer significantly influenced stem diameter, fresh weight, and dry weight, but not plant height, leaf number, and chlorophyll content. The interaction between NPK and Bokashi fertilizers significantly impacted plant height, fresh weight, and dry weight, though it had no significant effect on leaf number, stem diameter, and chlorophyll content.

Abstract

The availability of vital macronutrients from NPK fertilizer and the enhancement of soil fertility with bokashi organic fertilizer have a significant impact on the vegetative growth of green eggplant (Solanum melongena L.). This study aims to determine the effect of NPK, bokashi, and a combination of both on the chlorophyll content and vegetative growth of green eggplant. NPK fertilizer dosage (0 g, 1 g, 1.5 g, and 2 g) and bokashi fertilizer dosage (0 g, 100 g, 200 g, 300 g, and 400 g) were the two components in this study, which employed a completely randomized design (CRD) with three replicates. Plant height, leaf count, leaf area, fresh weight, dry weight, and chlorophyll content were among the metrics measured. ANOVA at the 5% level and DMRT were used to analyze the data. The findings demonstrated that the chlorophyll content and other vegetative growth indices were significantly impacted by NPK fertilizer. Chlorophyll content was not considerably impacted by the bokashi fertilizer application, however all vegetative growth indices were significantly impacted. With the exception of leaf area, the combination of NPK and bokashi fertilizers did not substantially affect most measures. The combination of 400 g bokashi and 2 g NPK yielded the highest vegetative growth indices and was the best treatment. Meanwhile, the combination of NPK 2 g and bokashi 300 g produced the maximum chlorophyll content. Through the use of integrated organic and inorganic fertilization, this study demonstrates how adding bokashi to NPK fertilizer can boost plant growth and nutrient use efficiency, helping to create sustainable farming methods.
