Abstract

Productions of crude palm oil (CPO) produce waste which include the empty oil palm fruit bunch (EOPFB), palm oil mill effluent, shells, and fiber. The combustions of shell and fiber as boiler feed produce waste in the form of boiler ash. Boiler ash is very potential to use as an additive to improve quality of the EOPFB compost. The objectives of this research were to study : 1) effect of boiler ash on the quality of the EOPFB compost, 2) effect of  EOPFB compost on the chemical properties of Ultisol, and the yield of mustard. The first experiment was about quality improvement of compost from EOPFB by the addition of boiler ash. The treatments applied were four dose levels of boiler ash: K1= 0%, K2 = 15%, K3 = 25%, and K4 = 35%. The second experiment was greenhouse pot experiment. This experiment was consisted of thirteen treatments with three replications arranged in completely randomized design (CRD). The treatments applied were: four types of compost from the first experimental results aplied to the soil with four dose levels, i.e : 0, 10, 20 and 30 Mg ha-1. The results showed that the addition of boiler ash at the beginning of the composting process improved the quality of  the EOPFB compost: which increased pH, amount of humic acids, macro and micro nutrients content and decreased content of Pb. The aplication of all compost –K1, K2, K3, K4– to Ultisol increased pH H2O, P2O5, organic-C, total-N, exchangeable-Ca, exchangeable-K and yield of mustard and decreased  exchangeable-H, exchangeable-Al. Moreover the yield of mustard was increased about 84% (33.9 g plant-1) with K4 at doses 20 Mg ha-1 and 85% (34.1 g plant-1) with K3 at doses 10 Mg ha-1.

Abstract

Coal ash and humic substances can be used as soil ameliorant in the reclamation of formerly mined land. Due to its high pH and nutrients content, coal ash can be used to improve the chemical properties of the soil, such as increasing of pH, and increasing the levels of nutrients availability in the soil. Humic substances may also be used to complement, as they can increase the release of nutrients from the coal ash. Thus, the objective of this study was to assess the influence of coal ash and humic substances on soil chemical characteristics, nutrient absorption, and plant growth. This study was conducted in two locations - in a nursery area, involving two treatment factors: coal ash at different dosages (0, 200, and 400 g polybag-1), and humic material also at varying dosages (0, 0.04, and 0.08 g C polybag-1); and in a post-mining field using similar treatments: coal ash dosage (0, 2.5, and 5.0 kg planting-1 hole) and humic material dosage (0, 0.56, and 1.12 g C planting hole-1). The results showed that coal ash and humic materials significantly increased the soil pH, available P, and exchangeable K, Ca and Mg. Coal ash also contained a number of heavy metals but in quantities that are far below the limits set by both Indonesian Government Regulation and the US Environmental Protection Agency (USEPA). The above soil amelioration effects mean that. applicaton of coal ash and humic substances can significantly increase the growth of Jabon trees in the reclaimed post-mining land.[How to Cite: Ade MO, Sudarsono, Iskandar and DT Suryaningtyas. 2014.

Abstract

This research was aimed to determine the differences of physical and chemical characteristics from three natural zeolites from Tasikmalaya, Bayah and Lampung areas and to examine the characteristics of the natural zeolite adsorption capability to the micro-nutrients. The zeolite characterization analysis included some variables i.e. mineral types, morphologyand pH, CEC (Cation Exchange Capacity), BSP (Base Saturation Point), Cu and Zn content of zeolite.  Analysis of natural zeolite adsorption characteristics were done by Batch System. Data interpretation were done by  using the isothermal adsorption equation of Langmuir, Freundlich and Brunauer-Emmett-Teller (BET).The results showed that zeolite from Bayah and Tasikmalaya had a similiar morphology and it was categorized as mordenite types and platy structure, while zeolite from Lampung was a clinoptilolite type and tabular structure. The CEC of Tasikmalaya zeolite (137.58 cmol(-)kg-1) was higher than Bayah (96.75 cmol(-)kg-1) and Lampung (87.72 cmol(-)kg-1). Adsorption capability at the Langmuir equation of Cu by Bayah zeolite (47.619 mg g-1) was higher than Lampung (33.333 mgg-1) and Tasikmalaya (28.571 mg g-1). Effective adsorption of Zn by Bayah zeolite 19.417 mg g-1 was higher than  Lampung (16.949 mg g-1) and Tasikmalaya (1.395 mg g-1).
