Abstract

Sweet corn Zea mays Saccharata Sturt is a food crop commodity that is in high demand because it contains carbohydrates The most important factor in increasing sweet corn production is improving soil nutrients by fertilizing The purpose of this study was to determine the effect of several types of organic matter on the growth and production of sweet corn This research was conducted at the Kassa House of the Faculty of Agriculture University of Pasir Pengaraian in Rokan Hulu Regency Riau Province from March to May 2022 This research was carried out using a Completely Randomized Design CRD method with 4 treatments P0 Without Addition of Organic Materials P1 75g solid plant P2 75g empty oil palm bunches tankos plant P3 75g rice husk plant The parameters in this observation were plant height number of leaves leaf width leaf length corn weight and level of sweetness sweetness but significant effect on corn weight parameters The P2 treatment 75 g of tankos plant tended to give the highest value on the parameters of the number of leaves leaf width and corn weight.

Abstract

RIZKI HANDAYANI, NIM 1827028. "The Effect of Giving Rice Husk Charcoal on the Growth and Production of Shallot Plants (Allium ascolanicum. L)". Supervised by Lufita Nur Alfiah, SP., M.Si and Rizah Rizwana Wahyuni, S.TP., M.Sc.Onion (Allium ascalonicum L) is a horticultural plant belonging to the vegetable and spice group as a food flavoring. Shallots are one of the leading vegetable commodities that have been intensively cultivated by farmers for a long time. Acidic soil is soil that has a low pH, generally acidic soil will reduce the level of land productivity for some plants. Soil conditions with low productivity levels require the addition of ameliorant. The ameliorant that can be used is rice husk charcoal. Rice husk charcoal can be used to improve the place where a plant grows and can function as a builder of soil fertility. This research was conducted to determine the effect of giving various doses of rice husk charcoal on the growth and production of shallot plants. This research was carried out at the Kassa House of the Faculty of Agriculture, Pasir Pengaraian University from May to August 2022. The design used in the study was a Completely Randomized Design (CRD) with 5 treatments, namely R0 = 0 g/polybag, R1 = 20 g/polybag , R2 = 40 g/polybag, R3 = 60 g/polybag, and R4 = 80 g/polybag. The results showed that the results were not significantly different with the administration of several doses of rice husk charcoal on all observation parameters. Parameters of plant height and fresh weight of tubers tended to be higher by administering a dose of rice husk charcoal 80 g/polybag. While administration at a dose of 40 g/polybag tends to be higher for the number of tubers planted compared to other doses.

Abstract

This research on the effectiveness test of Melastoma malabathricum L. plants as antibacterial agents for Salmonella was conducted from September to October 2023. The purpose of this study was to prove that Senduduk leaf extract (Melastoma malabathricum L.) is effective as an antibacterial against Salmonella typhi. The disc diffusion method was used as an antibacterial fraction to be tested by being absorbed on disc paper, the descriptive method was used to see the antibacterial ability which was arranged based on variations in solutions with 5 treatments in duplicate. Treatment with variations in senduduk leaf extract solutions of 20%, 40%, 60% and 80% and sterile aquadest as a control. The results of the study showed that the Melastoma malabathricum L. plant originating from the land of the Faculty of Agriculture is a plant that has a content in accordance with the phytochemical content described by (Afrianti M, Dwiloka B, Setiani B E, 2013). In The Inhibition Test, The Variation Of The 80% Leaf extract solution produced an inhibition zone with the largest diameter of 18.25 mm, this indicates that the Melastoma malabathricum L. leaf extract has better inhibition compared to the 20%, 40% and 60% leaf extract concentrations.
