Abstract

ABSTRACTPhosphorus (P) is a nutrient that is needed by plants. The availability of this element is greatly influenced by soil pH. As for ultisol soils classified as acid soils, most of the P in the soil is not available and is bound to Fe and Al. Pseudomonas, a phosphate solubilizing bacteria are soil microbes that can improve the availability of P in acid soils. This study aims to obtain Pseudomonas indigenous, a phosphate solubilizing bacteria from the acid soil formerly used by rubber plantations in the Institut Teknologi Sumatera. The study was conducted from April to June 2018 which included soil chemical analysis, isolation of the genus Pseudomonads on specific media, testing of phosphate solubility on solid Pikovskaya medium and simple pathogenicity test on potato tubers. The results showed that the sample soil was acidic with a pH of 4.09 with a P-availability of 0.78 ppm. From the soil samples, four potential isolates were obtained from the genus Pseudomonas, namely GSP 01, GSP 13, GSP 15 and GSP 06, with phosphate solubility indexes of 0.885, 0.639, 0.619 and 0.568, respectively. Isolates have the best phosphate solubilizing index on days 4 through 7. The four potential isolates are not pathogenic, so they can be used as isolates to improve the availability of soil nutrients, especially phosphorus needed by plants.Keywords: acid soil, phosphate solubilizing bacteria, phosphate availability, PseudomonasABSTRAKFosfor (P) merupakan unsur hara yang sangat dibutuhkan oleh tanaman.

Abstract

The peat fire events in Indonesia, particularly the South Sumatra area, changed the appearance of surface vegetation. The fires usually occur during the dry season from July to October. This study aims to evaluate land cover changes due to 2015’s peat fire in the South Sumatra peatlands. Remote sensing techniques using a Normalized Difference Vegetation Index (NDVI) method were used to identify the change of vegetation density in the study area. The results showed that 69% of the total South Sumatra peatland was burned due to the 2015 peat fire event. The level of vegetation density was considerably decreased by fire events. The degradation in the burned area was dominated by land cover class of ferns/shrub. The Peat fires during the observation period have a negative impact on the peat ecosystem, so improvements are needed in peatland management practices. Improvements need to be made in fire prevention and management practices, as well as restoration of burnt land.

Abstract

Oribatids are one of the important fauna groups in the soil. They have an important role in the decomposition of organic matter in the soil. The objection of this research was to study population dynamics of Oribatids through determining the abundance and diversity of Oribatids and to know the effect of environmental factors on Oribatids in oil palm plantation at Bajubang, Batanghari, Jambi. Soil and litter samples were taken from four different locations (25 m x 25 m) and from each location three samples were taken from litter lanes and open lanes, respectively (the size was 16 x 16 cm with a depth of soil is 5 cm). The samples were extracted using Kempson extractor. Identification of Oribatids was done to the family level and the diversity of Oribatids was measured using Shannon’s diversity index. The population dynamic of Oribatids showed a fluctuation in the sampling period. When rainfall increased >200 mm did not follow by increasing abundance and diversity (number of the family) of Oribatid mites. When rainfall between 100 – 200 mm was the optimal condition for Oribatids so abundance and diversity (the number of the family) of Oribatids increased. But, when rainfall <100 mm especially in February 2014 (the lowest rainfall 1 mm), abundance and diversity (number of the family) of Oribatids was lowest (330 individual m-2; 7 families) compared to another month. It was assumed that Oribatids may migrate into the deep soil to avoid a harsh environmental condition. Abundance and diversity (number of the family) of oribatids were significantly higher in litter lanes (4,560 individual m-2; 25 families) than in open lanes (1,570 individual m-2; 14 families). The availability of litter in the litter lanes was higher than in open lanes. In this research, There are 3 families that most abundance and always found on the sampling period, they are Scheloribatidae, Mycobatidae and Galumniidae. Keywords: Abundance, diversity, oil palm plantation, Oribatids, soil fauna

Abstract

Low-cost adsorbents from cassava leaves (CLP) were prepared by simply washing the leaf powder with deionized water. The adsorption of methylene blue (MB) from the aqueous solution was measured in order to examine the adsorbent performance. The effect of the pH of the solution was studied by varying pH from 2 to 10. The kinetics of MB adsorption onto CLP followed the pseudo-second-order kinetic model with a k-value of 0.087907 g mg-1 min-1 and 0.094081 g mg-1 min-1 for CLP before and after washing, respectively. The adsorption isotherm for both adsorbents followed the Langmuir isotherm model with qm values of 178.5 mg g-1 and 243.9 mg g-1. The existence of disturber ions was investigated by adding NaCl into the MB solutions at a variety of concentrations.

Abstract

Peat fire is one of the most environmental issues in Indonesia, particularly in the region of South Sumatra. The fires usually occur during the dry season from Juni to November. This study is designed to evaluate the impact of peat fires on changes in land cover in the Merang Kepahyang Peat Hydrological Region (MK-PHR) for the period of 2002 to 2015. The changes identified by the Normalized Difference Vegetation Index (NDVI) method using Landsat satellite imagery. The results of the study show that extreme peat fire associated with climate anomalies events occurred in 2006, 2012, and 2015. The largest peat fires during the observation period occurred in 2015 coincided with extreme climate anomalies generating negative changes in land cover in the most of MK-PHR areas. The changes occurred in almost half (49%) of the MK-PHR area, where it moved from the dense to moderate vegetation class. The spatial and temporal land cover changes will be discussed in more detail.

Abstract

Ganoderma philippii and Fusarium oxysporum 0148c are the primary pathogenic fungi that causes root rot and damping-off in young acacia plants. The best treatment to date is the use of biological control agents. Phosphate solubilizing bacteria (PSB) isolated from acid soil is a bacterial isolate classified as plant growth-promoting bacteria (PGPB). PGPB has an indirect function as a biocontrol agent for fungal pathogens. This study aimed to determine the potential of PSB isolate EF.NAP 8 in inhibiting G. philippii and F. oxysporum 0148c from acacia plants. The method used is a dual culture antagonism test and observation of abnormal hyphae after the antagonism process. The results showed that the isolate EF.NAP 8 inhibited G. philippii by 34.44% and F. oxysporum 0148c by 33.33%. The abnormality of hyphae after antagonistic activity results in hyphal malformations such as hyphae lysis and hyphae coiling. The antagonistic activity of PSB EF.NAP 8 isolate is one of part of the ability of a bacterium classified as PGPB in the form of biocontrol activity against pathogenic fungi. This provides information regarding the opportunity to utilize EF.NAP 8 as a candidate agent for controlling fungal pathogens on acacia plants.

Abstract

Waste is an environmental issue that quite unsettling right now. Hospitals are health facilities for community but also become one of waste contributor. Waste from hospital activities was called medical waste. Medical waste can be a source of disease for humans and other living organism and can disrupt environmental stability if not managed properly. The management of medical waste must be appropriate with regulations, but there are still many health facilities that have not managed according to the regulations. This study was conducted to evaluate of medical waste management in hospital to government regulation No. 101/2014 and Regulation of environment and forestry minister No. 56/2015. The research was conducted through several step from literature study to direct survey in the field through interviews and observations of the medical waste management. That information is evaluated in accordance with the waste management that has been regulated in government regulation No. 101/2014 and regulation of environment and forestry minister No. 56/2015. There are seven activities in the management of hazardous and toxic waste but this hospital only carry out two steps, such as collection and storage activities. Some of their doing in collection and storage activities was still not accordance with the regulations.
