Abstract

The research aimed to determine the type of foliar fertilizer and container for the flowering phase of lunar orchids. The study was conducted from November 2021 to February 2022, using a completely randomized design with two treatment factors and eight treatment combinations repeated three times. The combinations of these treatments are (a) Type of plastic container and Gandasil B leaf fertilizer 1 g/l (P1G1); (b) Type of plastic container and Gandasil B leaf fertilizer 2 g/l (P1G2); (c) Type of plastic container and Vanda's leaf fertilizer 1 g/l (P1G3); (d) Type of plastic container and Vanda's leaf fertilizer 2 g/l (P1G4); (e) Type of container for coconut coir and Gandasil B leaf fertilizer 1 g/l (P2G1); (f) Type of container for coconut coir and Gandasil B leaf fertilizer 2 g/l (P2G2); (g) Type of container for coconut coir and Vanda's leaf fertilizer 1 g/l (P2G3) and (h) Type of container for coconut coir and Vanda's leaf fertilizer 1 g/l (P2G4). Observations included parameters: number of leaves, leaf width, leaf length, when the stalk appears, stalk length, and number of flowers. The results showed that there is an interaction between the type of container and foliar fertilizer in supporting the flowering of Phalaenopsis sp. This type of coir container with Gardasil B fertilization of 2 g/l can produce flower stalks about seven months after transplanting and at the age of 8 months, the flower stalk length reaches 12 cm with the number of flower buds 2 – 3 buds per plant.

Abstract

The research aims to obtain the concentration and immersion time to increase the essential oil content, growth, and yield of ginger plants. This research used a split-plot design, with the main plots of ginger varieties and subplots of colchicine immersion time. Parameters observed included stem morphology, leaf morphology, root morphology, rhizome morphology, and essential oil content. The research results show that the optimal immersion time of colchicine with a four ppm dose to increase productivity in the three varieties of ginger was 12 hours. Immersion of 16 hours would reduce the productivity of ginger plants. Immersion using colchicine for 12 hours on white ginger and small white ginger varieties was able to increase the essential oil content to 1.79% and 2.31%, and also increasing essential oil would optimize for red ginger with immersion time for 16 hours was become 2.75%.

Abstract

This study aimed to produce a recommendation to the public and the government related to efforts to deal with the problem of the visual aesthetic quality of the landscape, especially in the garden landscape. The garden landscape is necessary to evaluate visual quality using assessment methods, namely Scenic Beauty Estimation (SBE). The methods produce low, medium, and high visual aesthetic quality categories where the relationship between them supports or does not support each other. The result showed dominant results are mutually supportive or appropriate on high-value playground areas and low-value soccer fields. The Welcome Area, Rest Area, and Infiltration Area have result that does not support each other with different quality values for each photo. Recommendations in this area are adjusted to the results of the assessment based on each method in the form of design concept recommendations that lead to the SBE method.

Abstract

This study aimed to identify and know the associated insects and their role in sweet corn plants. This study used a non-factorial randomized block design (RBD) with three kinds of treatment; yellow traps, net traps, and ground traps. Each treatment was repeated nine times so that there were 27 experimental units. In each treatment plot, the sample size is 3m x 1m. Sampling of insects on corn plants using net traps, yellow traps, and soil traps. The result showed that found 1,012 insects, from 8 Ordo and 25 families in sweet corn plants. In the vegetative phase found 636 insects in various roles. 408 insects are pests and 228 insects that are natural enemies. A total of 406 insects were found in the generative phase, 196 of which were pests and 210 were natural enemies.
