“…According to studies by Martin et al [25], the element nitrogen is important for the division and growth of cells that take place in the apical meristem, which is why it is required for the development of buds and leaves. Supported by Muningsih's assertion that, in addition to the nitrogen content, which actively contributes to the growth of leaves, coffee grounds also contain magnesium and carbohydrates that can aid in the production of chlorophyll and speed up the development of leaves.…”

“…This is because composted coffee grounds contain nitrogen, which can promote the increase of the number of leaves that contribute to the creation of chlorophyll, making leaves greener and promoting shoot growth. Providing enough nitrogen can boost protein synthesis and plant development.According to studies by Martin et al[25], the element nitrogen is important for the division and growth of cells that take place in the apical meristem, which is why it is required for the development of buds and leaves.

The deficiency of productive agricultural land was an obstacle to the development of mustard green cultivation. The utilization of acid-dry land is a solution for the development of mustard green cultivation. South Kalimantan has acid-dry land covering an area of 87.61% of the total dry land. The use of coffee grounds compost is an alternative technology for improving soil fertility in acid dry land. Coffee grounds compost can increase soil organic matter, so it can fertilize the soil and increase crop production. This study aims to determine the quality of coffee grounds compost and determine the best dosage of coffee grounds compost to increase soil pH, growth, and production of mustard greens in acid dry land. This research method used a single-factor randomized block design (RBD), namely the dose of coffee grounds compost: k0 = 0 t ha−1; k1 = 10 t ha−1; k2 = 20 t ha−1; and k3 = 30 t ha−1. The physical and chemical characteristics of coffee waste compost have met the criteria for quality compost based on SNI No. 19-7030-2004. The results showed the effect of coffee grounds compost on increasing soil pH, growth, and production of mustard greens. The best dose of coffee grounds compost in increasing soil pH, plant fresh weight, and mustard productivity was found in the K3 treatment with increases of 18.05%, 67.21%, and 67.21% respectively compared to the control. The best treatment for increasing plant height, number of leaves, and width of mustard leaves was treatment k1 with an increase of 51.34%, 31.03%, and 40.60% respectively compared to the control.

Arbuscular mycorrhizal fungi (AMF) are naturally found in the soil. The population of this fungus is influenced by environmental factors such as soil type. Different soil types have different characteristics and will affect the AMF population in the soil. Therefore, this study was carried out to determine the AMF population in the soil based on the number of spores in the rhizosphere of oil palm planted in 4 different soil types, namely Dystrudepts, Paleudults, Haplohumods, and Haplosaprists. Soil samples were taken from each soil type at 4 sample points. At each sample point, soil samples were taken from 5 adjacent oil palm trees. Rhizosphere soil samples were taken at 4 points inside the oil palm circle at a depth of up to 15 cm and 4 points from the outside and then composited to represent 1 sample point for inside and outside the circle. Extraction of AMF spores from soil samples was carried out by the wet sieving method. The results showed that the average number of AMF spores per 50 g of rhizosphere soil from inside and outside the oil palm circle were 66,7 and 53,5 spores for Dystrudepts, 115,5 and 91,5 spores for Paleudults, 27 and 71,8 spores for Haplohumods, and 83,3 and 55 spores for Haplosaprists respectively. In Dystrudepts, Paleudults, and Haplosaprists soil types, the number of spores in the rhizosphere of oil palm inside the circle was higher than outside. On the other hand, for Haplohumods soil types, the number of spores inside the circle was lower than outside the circle.

This study aims to determine the best clone species and the best dosage of Salvinia natans compost on the growth and physiological character of lowland tea. This study aims to determine the best types of clones and dosage of Salvinia natans compost for growth and physiological character of lowland tea. This study used a randomized block design experiment with three replications arranged in factorial 2x4. The first factor is a type of clones consists of two (2) levels, namely: Gambung 6 (G1) and Gambung 7 (G2). The second factor is the dosage of Salvinia natans compost with topsoil 100% (K0), topsoil and Salvinia natans compost comparison by1: 1(K1), topsoil and Salvinia natans compost comparison by2: 1(K2), dan topsoil and Salvinia natans compost comparison by3: 1(K3). All data were analyzed for the variance. Analysis followed by separation of means using LSD test with significance level of 5%. The results showed that the clones of Gambung 7 showed the higher value for observation variability in higher growth of seedlings (40,75) and better dry weight(10,78 g). Topsoil planting medium comparison by Salvinia natans compost (1: 1) showed the higher value for observation variability in higher growth of seedlings (42,25) and better dry weight (10,95 g). So, the conclusion is Gambung 7 for the best clone species on the growth and physiological character of lowland tea. The best dosage of Salvinia natans compost on the growth and physiological character of lowland tea is topsoil planting medium comparison by Salvinia natans compost (1: 1).
