Abstract

Background: Phalaenopsis amabilis, or the moon orchid, is a popular type of orchid with high market demand. Planting media is a factor that can be successful in caring for the Phalaenopsis amabilis, which is an epiphytic orchid type or attaches to other plants. Most orchid planting techniques have not been adapted to their natural habitat in nature that attaches to other plants. The planting medium generally used for epiphytic orchids such as Phalaenopsis amabilis is fern boards, which are limited in nature. Researchers see the potential for coffee wood. Many can be used as a planting medium for Phalaenopsis amabilis because this plant is also found growing naturally in coffee plants. Methods: The research used comparative studies between coffee sticks and fern boards as planting media for Phalaenopsis amabilis on their vegetative growth according to their natural habitat by attaching to other plants. The analysis results were obtained by statistical tests t–test unpaired) using SPSS. Results: The analysis showed p ≤ 0.05 on the four parameters of Phalaenopsis amabilis growth. There are differences in the use of planting media types of coffee logs (M1) and fern boards (M2) on the vegetative growth of Phalaenopsis amabilis orchid plants, including the number of leaves, leaf span, leaf width, and root length. Conclusions: The vegetative growth on M1 and M2 is significantly different. The fern board planting media (M2) tends to be more recommended for use. After all, it can be optimal in providing vegetative growth consisting of the number of leaves, leaf span, leaf width, and root length because its growth is more stable.

Abstract

Background: Combining the right bioactivator and biochar dosage can speed up the process and increase the compost quality. Using compost in agriculture can reduce the excessive use of chemical fertilizers, improve soil health and crop yields, and contribute to overall agricultural sustainability. Methods: The research was conducted in March-August 2021 in Kemantren Village, Tulangan District, Sidoarjo Regency. Analysis activities were conducted at the Land Resources Laboratory, Faculty of Agriculture, UPN "Veteran" East Java. This research uses a factorial experimental design based on CRD (Completely Randomized Design) and consists of two factors. Factor 1 is the type of bioactivator, namely: A0: Control; A1: Cattle Farmer; A2: Tapai; and A3: Banana Beetle. Factor 2 provides biochar: B0: Control; B1: 200 grams; and B2: 300 grams. Observation data were analyzed using Analysis Of Variance (ANOVA). Then, if there is a real difference between treatments, the Honest Significant Difference (BNJ) test is carried out with an error rate of 5%. Results: The research results showed that the best compost was the use of a banana hump cultivator, while the best biochar was 200 g. The best results from the combination of bioactivator and biochar were the application of 200 g of cow manure and banana hump bioactivator. Conclusions: The combination of banana stem bioactivators and cow dung with 0 gr biochar (control) improved the quality of the chemical properties of the compost. In contrast, adding biochar at both 200 g and 300 g concentrations showed improvements in the physical quality of the compost texture.
