Abstract

The effect of shallot peel (Allium ascalonicum L.) as a natural growth regulatory substance on root growth of cassava stem cuttings (Manihot utilissima). This study aims to determine the effect of shallot peel extract on root growth of cassava stem cuttings and determine the most effective treatment for root growth of cassava stem cuttings. This study used a completely randomized design consisting of 1 factor, namely the treatment of shallot peel extract concentration which had 10 levels (concentration 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80 %, 90% and 100% of shallot peel extract) and 3 replicates. The variables observed in this study were the number of roots and the longest root length from the roots of cassava stem cuttings. The data obtained were analyzed using the ANOVA test and the HSD (Honestly Significance Different) follow-up test with an error rate of 5%. The results showed that the treatment of shallot peel extract had a significant effect on the root growth of cassava stem cuttings. The most effective concenstration of shallot peel for root number growth was 20%, while for root length growth the most effective concentration was 30%.

Abstract

Seagrass has high productivity so it is said to be a complex shallow marine ecosystem. The role of seagrass ecosystems is very important, especially in terms of ecological and economic functions. The purpose of this research is to reveal the existing condition of the seagrass ecosystem. Data collection used the line transect method with a square measuring 1m x 1m. The sampling technique uses a systematic random sampling method. The results of the study obtained 4 species and 2 families, among others: Hyddrocharitaceae including Enhalus acoroides, and Thalassia hemprichii. The Potamogetonaceae family consists of Cymodocea rotundata, and Syringodium isoetifolium. Seagrass species that have a high enough influence on seagrass ecosystems in Gili Sulat waters are Thalassia hemprinchii, with an important value index (INP) of 184.74, a density value of 65.59% (rather dense status), a frequency of 48.21% (wide enough distribution), and 70.84% coverage (rich/healthy status).

Abstract

Long beans are plants of the Leguminoceae family that grow on vines. Long bean growth rate is influenced by various factors. Some of the external factors that determine the growth rate of long beans are the availability of nutrients and the application of mulch on agricultural land. Research on the vegetative growth response of long bean due to different types of mulch and doses of vermicompost fertilizer has been carried out in Mertak Umbak Village, Central Lombok. This study aims to analyze: (1) the vegetative growth response of long bean due to different types of mulch, (2) the vegetative growth response of long bean due to different doses of vermicompost, (3) the effect of a combination of types of mulch and vermicompost dosage on long bean growth. Research data were analyzed using Anova. The research results show that: (1) the vermicompost treatment significantly affected the increase in total leaf and plant height, but did not have a significant effect on the length and width of long bean leaves, (2) the application of mulch had a significant effect on all observed growth parameters, the highest growth parameters were observed in the application of plastic mulch black silver, (3) the interaction of mulch type and vermicompost dosage had a significant effect on plant height but did not have a significant effect on other growth parameters.

Abstract

This study aims to determine the effect of vermicompost, urea fertilizer and the interaction of vermicompost and urea fertilizer treatments on corn vegetative growth. The research design used was a 2-factor design. The first factor was the application of vermicompost and the second factor was the application of urea fertilizer which was carried out with 3 replications. The doses of vermicompost were 0, 0.5, 1.0, 1.5, and 2.0 kg. The doses of urea fertilizer were 0, 0.6, 1.2, and 1.8 g. The research data were analyzed using Anova. The results of the study were: Vermicompost treatment had a significant effect on stem height, number of leaves and leaf length but had no significant effect on leaf width and corn stem diameter; application of urea fertilizer could increase all measured corn growth parameters; interaction between urea fertilizer and vermicompost treatment had no significant effect on all measured corn growth parameters.
