Evaluation of nitrate and phosphate content in seawater of Jungwok Beach, Gunungkidul District, Yogyakarta, was the aim of this study. The method used was a survey with a quantitative approach. Sampling in the eastern, central and western regions of Jungw... see more

The production of phosphate concentrates is confronted with problems of treatment of wastes, of which the quantities are considerable. These wastes contain a large number of elements that are harmful to the environment. In this case, of phosphate wastes f... see more

AbstractPhosphate scarcity will occur if humans do not currently manage the phosphates available in nature with good management. Phosphorus rocks are a natural source of phosphates, whose availability in nature is dwindling due to the large demand for pho... see more

A composite of hydroxyapatite modified silica (HASiO2) and 10% (w/w) polyeugenol (PE) was synthesized to produce a calcium phosphate cement with antibacterial activity. The compatibility of the composite (HASiO2_PE) with bone filler requirements was deter... see more

Eutrophication / Fertility of waters is an event of increasing organic matter and nutrients (especially nitrogen and phosphorus elements) that accumulate in water bodies. Eutrophication can occur due to two factors, internal factors and external factors. ... see more

Nanotechnology fertilizers are fertilizers associated with objects measuring 1 nm to 100 nm capable of controlling or manipulating at an atomic scale. Phosphorus is one of the essential nutrients needed by plants in large amounts. Maize is a strategic com... see more

In soil, a large amount of supplemented phosphorus (P) are immediately transferred into insoluble forms and only 0.1 % of them is available for plant uptake. Therefore, exploring naturally occurring phosphate-solubilizing microorganisms is an essenti... see more

The clay used taken from Lontor Village, Central Maluku Regency, Banda Besar Island. The clay was activated at 350 °C for 3 hours using a furnace. This study aims to determine the effectiveness of physically activated Lontor natural clay in reducing level... see more

Amorphous iron phosphate, FePO4.2H2O, was synthesized at ambient temperature using an inorganic sol-gel method coupled with a microwave route. The experimental conditions for the gelling of the Fe (III)-H3PO4 system are defined.  Potentiometric Time ... see more
