Abstract

Kiambang (Salvinia natans) which a water plant became a seriously problem in the use of Reservoir Batutegi, because nearly 80% of its surface covered by Salvinia natans. The presence of highly abundant of Salvinia natans have highly potential to be used as a source of organic fertilizer. The purpose of this study was to examine the effect of the application of biological technology (decomposers) and cow manure on the quality of the resulting compost kiambang. This study used randomized block design and experiment arranged in factorial 4 x 4 with three replications. The first factor was the dose of decomposers which consists of 4 levels, namely A1 = 0 ml, A2 = 20 ml, 30 ml dose = A3, and A4 = 40 ml decomposers per quintal kiambang respectively. The second factor was the dose of cattle dung, i.e. B1 = 0 kg, B2 = 10 kg, 20kg = B3, and B4 = 30 kg manure per quintal kiambang. The results showed the compost that has the best quality in terms of physical and chemical compost was the compost derived from the treatment of 30 ml and 40 ml decomposers per quintal kiambang which combined with 10 kg, 20 kg or 30 kg manure per quintal kiambang.

Abstract

Indonesia is one of the world's most enormous vanilla (Vanilla planifolia A.) producing countries. Propagation of vanilla plants by vegetative means using cuttings consisting of 1-3 segments, each node of vanilla has the potential to remove roots and shoots so that with this potential, it is possible for vanilla to be propagated by cuttings. Still, the growing ability is meagre, so special treatment is needed by giving plant growth regulators (PGR). Information regarding using NAA on the growth of vanilla cuttings has not been found. Therefore, this study was conducted to obtain the best NAA concentration for the growth of vanilla seedlings. This research was carried out from July - November 2021 in the experimental garden of the Politeknik Negeri Lampung. The method used was a single factor Randomized Block Design (RBD) with five treatments and five replications, so there were 25 experimental units. The treatment consisted of five levels, namely 0 ppm (R0), 100 ppm (R1), 200 ppm (R2), 300 ppm (R3), and 400 ppm (R4). The data was analysed using the F test. If there is a difference, proceed with the HSD test at the 5% level. The results showed that the 200 ppm (R2) NAA concentration gave the highest average value for several variables, namely, shoot height (16.86 cm), number of leaves (4.68), number of internodes (4.84), and root length (57.05 cm) at the age of 30 DAP to 120 DAP.

Abstract

Weeds are highly undesirable plants in plantation areas, including robusta coffee plants. This is as a result of the presence of weeds that might minimise the productivity of robusta coffee plants. Currently, various types of weeds found in robusta coffee plants are known. This study aimed to enumerate the types of weeds found in robusta coffee plants. The research was conducted in June 2023 in robusta coffee plantations in Wiyono Village, Gedong Tataan, Pesawaran, Lampung Province. The research was conducted by purposive sampling with the plot method. The analysis showed that the composition of weeds in coffee plants consisted of 9 families and 14 species. Ageratum conyzoides appeared to dominate the coffee plants with the highest Summed Dominance Ratio (SDR) value (46.08%).  The weeds diversity index (H') in coffee plants was 0.823 and the dominance index was 0.636576.
