Abstract

Acid sulfate soils are one of the potential lands for agriculture with appropriate treatment. The main problem in these soils is the chemical properties, which is high in acidity and limited nutrients availability and Fe and Al toxicity. Amelioration techniques are needed to improve the chemical properties of the soil, which is oyster mushroom baglog waste compost. This research aims to study the effect of oyster mushroom baglog waste (OMBW) compost to soil chemical properties, also to know the best dosage which affects chemical properties. The research was conducted at the greenhouse of the Agroecotechnology Department and the Laboratory of the Soil Department, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The research was started from August-October 2020. One-factor completely randomized design (CRD) with five treatments and five replications was used, the b0 treatment was not OMBW compost, b1 was 5 t ha-1, b2 was 10 t ha-1, b3 was 15 t ha-1, and b4 was 20 t ha-1. The application of the OMBW compost significantly affected the soil pH and decreased soluble-Fe and Al, but did not significantly affect the Eh value at 2 WAA (Week After Application). The best concentration of dose of OMBW compost was 10 t ha-1 which improved soil pH, decreased soluble-Fe and Al.

Abstract

In recent years, the amount of coffee consumption by the Indonesian people has increased. As a result, there is an increase in coffee waste in the form of coffee grounds so it has the potential to have a negative impact on the environment. Proper management is needed so that coffee grounds are not wasted and pollute the environment. Composting is one way to convert coffee grounds into organic fertilizer. The provision of decomposers is useful for accelerating the composting process of coffee grounds so that it affects the quality of the compost produced. This study aims to determine the chemical quality of coffee grounds compost using different decomposers based on the Indonesian National Standard (SNI) 19-7030-2004. This research was carried out in the Compost House Department of Agroecotechnology and Soil Laboratory Department of Soil Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru for three months, from June to August 2021. This research uses quantitative methods (laboratory analysis) to determine the chemical quality of coffee grounds compost. The treatments were decomposers, d1 = EM4, d2 = M21, d3 = Beka, and d4 = Petro Gladiator. The results showed that the use of EM4, M21, BeKa, and Petro Gladiator decomposers produced organic C, total N, P2O5, K2O, Ca, Mg, and C/N ratio of coffee grounds compost in accordance with SNI 19-7030-2004, but the pH value of coffee grounds compost treated with EM4, M21, BeKa, and Petro Gladiator decomposers did not meet SNI 19-7030-2004.
