Abstract

Oil palm fronds are waste products of oil palm plantations that are not utilized, yet oil palm fronds can be converted to biochar to improve soil fertility. This study aimed to analyze the chemical properties of the biochar generated from oil palm fronds. A pot experiment was conducted in Negeri Lama Seberang Village, Labuhanbatu District, Rantauprapat. The biochar formulation consisted of two formulations, i.e., A = pure biochar  (biochar in its original form) and B = granule biochar (biochar + tapioca flour). Each biochar form was repeated five times to obtain ten samples. The results of biochar laboratory analysis were continued with statistical tests based on the dependent t-test at the 5% level using Microsoft Excel. The results showed that biochar granules had chemical characteristics such as organic C of 32.78%, N of 2.39%, P of  0.18, K of 0.75%, and pH of 8.07. These values showed that granule biochar has better chemical characteristics than pure biochar.

Abstract

Soil biological properties are various aspects related to the life of microorganisms and macroorganisms in the soil and biological activities. This study aims to understand how soil organisms and their biological activities contribute to soil fertility and plant health. This study used a purposive sampling method and was analyzed using descriptive analysis. Soil biological properties, including the total number of bacteria and fungi, were observed to assess the effect of Black Soldier Fly larvae (kasgot) fertilizer application. The results showed that treatment variations had a significant effect on the population of fungi and bacteria in the rhizosphere. The highest value of the fungal population was recorded in the M1 treatment without the first treatment, while the lowest value was in the M1 treatment with the first treatment, indicating that the type and frequency of treatment can drastically affect fungal growth. For the bacterial population, the M3 treatment in the first application showed the highest effectiveness, while the M2 treatment in the second application showed the lowest results, highlighting the importance of the dose and application stage in increasing the bacterial population. Overall, this study emphasizes the importance of selecting the right treatment to optimize the soil microbial population in agricultural practices.

Abstract

Regular use of organic fertilizer can improve soil health, reduce erosion, and increase agricultural sustainability by reducing dependence on synthetic chemicals. Kasgot fertilizer or used maggot fertilizer is a type of organic fertilizer produced from maggot droppings (larva lalat Black Soldier Fly) after they decompose organic waste. This fertilizer is rich in essential nutrients such as nitrogen, phosphorus and potassium, and contains various beneficial microorganisms that help increase soil fertility. This research aims to determine the effect of cassava fertilizer on the growth of cucumber plants (Cucumis sativus L.).This study used non-factorial RAK with 4 administration dose levels, namely: M0= 0 grams/planting hole, M1= 5 grams/planting hole, M2= 10 grams/planting hole and M3= 20 grams/planting hole. Data were analyzed using analysis of variance tests on the parameters of plant height, number of leaves and root weight. The results of the research showed that the parameters of plant height and number of leaves showed significant differences between plants aged 2 WAP and 4 WAP, while root weight did not have a significant difference between treatments and each replication. Additional doses or other organic materials are needed to increase the macro nutrients available in the soil.

Abstract

Chili pepper (Capsicum frutescens) is one of the important horticultural commodities in Indonesia, widely cultivated due to its spicy flavor and high economic value. This study aims to compare the effectiveness of various planting media and fertilizers in promoting the environmentally friendly growth of chili pepper plants. The study employed a Factorial Randomized Block Design (RAK) with treatments including: Control (without cow manure), 2 kg of cocopeat and 1 ounce of cow manure, 2 kg of cocopeat and 1.5 ounces of cow manure, 2 kg of cocopeat and 2 ounces of cow manure, 2 kg of soil and 1 ounce of cow manure, 2 kg of soil and 1.5 ounces of cow manure, and 2 kg of soil and 2 ounces of cow manure. Data analysis was conducted using ANOVA and BNT post-hoc tests. The results showed that the planting media did not significantly affect plant height or the number of leaves, though variations in values were observed across treatments. In cocopeat media, the treatment of 2 kg of cocopeat and 1.5 ounces of cow manure resulted in the highest plant height at week 4, measuring 30.03 cm, followed by 2 kg of cocopeat and 1 ounce of cow manure (29.23 cm), 2 kg of cocopeat and 2 ounces of cow manure (29.20 cm), and the control treatment (28.46 cm). The highest number of leaves was also found in the 2 kg of cocopeat and 1.5 ounces of cow manure treatment, with 16.66 leaves, although in the second week, the control treatment recorded only 6.33 leaves. In soil media, the 2 kg of soil and 2 ounces of cow manure treatment produced 17.66 leaves, with variations in the second week noted between the cow manure treatments and the control group.
