Effect of Endopytic Bionematicide Bacillus SP. on the Infection of Meloidogyne SP. of Coffee Plant

Meloidogyne sp. is an important pathogen of coffee plant. Bacillus sp. is commonly used to control the nematode as it is environmentally friendly. The study aimed to determine the effect of endophytic bacteria Bacillus sp. PG76 formulated in the molasses, talc or compost on the infection of Meloidogyne sp. The experiments were conducted in the laboratory and greenhouse of the Indonesian Industrial and Beverage Crops Research Institute, Sukabumi from December 2013 to May 2014. The experimental design was a completely randomized, 6 treatments and 10 replications of six months-old coffee plants. Six treatments were tested (Bacillus sp. PG76 formulated in molasses, compost, or talc; carbofuran; plant inoculated with the nematode only, and plant neither treated with the formula nor the nematode). Population of Bacillus sp. PG76 in each formula was 109 cfu/ml. Number of formulas applied per plant was 100 ml of molasses, 100 g of talc, or 100 g of compost. One week after the treatments, the plants were inoculated with 500 larvae-2 Meloidogyne sp. Parameters observed were the number of gall, nematode population in the roots and soil, and the coffee plant growth. The results showed that all the treatments (molasses, compost, and talc) suppressed the population of Meloidogyne sp. The best formulas were molasses and compost that reduced the nematode infection up to 74.0% and 73.2%, respectively, similar to that of carbofuran (i.e. 73.3%). Furthermore, application of the formulas increased coffee plant growth. The study suggests that Bacillus sp. PG76 formulation is prospective to control the nematode

Pertumbuhan Benihikan Baung (Hemibagrus Nemurus) Dalam Keramba Jaring Apung Yang Diberi Pakan Buatan Dengan Kadar Protein Berbeda [Growth of Green Catfish (Hemibagrus Nemurus) Fry in Floating Net Cage Feed by Artificial Food with Different Protein Content]

The study was conducted to evaluate different protein content of feed on the growth performances of green catfish (Hemibagrus nemurus). Two thousands fingerlings (3.92 ± 0.32 g in averaging of individual body weights) were stocked in each of floating net cage (3x3x3) m3. They were fed daily for four months with diets containing protein content of 27% and 31%. The feed was given in pellet form at 4-8 % of total body weight. Result of this study showed that the fish feed with 31 % protein content gave better growth performances than it with 27 % protein feed. The feed contain of 31% protein was optimum for green catfish fingerlings and gave a higher average individual weight gain (80.48 g), specific growth rate (2.67%), fat retention (29.48%), and better feed conversion ratio (2.28). Survival rates were si-milar for two treatments and ranged between 94.17 to 95.18%

Application of Electrical Resistivity Tomography (ERT) and Arial Photographs Techniques in Geo Hazard Assessment of Karst Features in Constructing Sites in Perak, Peninsular Malaysia

This paper illustrates the application of geophysical survey, aerial photographs and satellite images as identification techniques for geohazard assessment of karst features in housing complexes construction sites north of Ipoh city, Perak state, Peninsular Malaysia. The engineers in Perak  face numerous problems while designing structures that would be situated over marbleized limestone (carbonate) karst terrains, due to its categorization to various bedrock solution features such as sinkholes, caves, cavities, depressions, conduits enlarged joints and fractures, and internal drainages, which directly exerts a negative impact on the use of this land for construction projects and structures. Furthermore, it can also indirectly have the potential to cause catastrophic damages in the near future perhaps many years after the project has ended.  The subsidence damages which result in construction works will cause massive losses which maximize the project overall cost leading to enormous financial costs, to the developers and the lands. In this study, Two-dimensional (2D) electrical resistivity tomography (ERT) survey was performed across three housing complex construction sites north of Ipoh in order to image the subsurface and locate evidence for near surface karstic features such as voids or cavities, including sinkholes and to estimate the depth of the bedrock. It is also done in order to estimate whether geophysical techniques are capable of identifying such features.  Six resistivity traverses or profiles were conducted along the survey area at each of the three construction sites. The orientation, extension and the degree of inclination of those profiles are shown in Google’s satellite map. The interpretation of the geophysical data indicated that both low resistivity and high conductivity anomalies extends along the proposed area in all of the construction sites. The ambiguous anomalies observed in construction site # 1 indicated that the area has been exaggerated by a sinkhole, thus it contains non-stiff clay and is saturated with water, rendering it less resistant to electrical currents (high conductivity). The ambiguous anomalies observed in construction site #2 indicated that the area has been affected by several sinkholes and tubular anomalies containing both stiff and sandy clay. The anomaly observed in construction site #3 indicated that the area has been affected by several soil cover collapse sinkholes and tubular anomalies containing stiff, non-stiff and sandy clays. This study also demonstrated that high-resolution Electrical Resistivity Tomography (ERT) can be effectively applied to reflect and differentiate surficial soil, clay, weathered rocks, compact or intact rocks, and air-filled karstic voids or cavities. The appearance of many sinkholes in the area is mostly attributed to karstic activity. In accordance to the classification of the characteristics of morphological features of karstic ground conditions by (A. C. Waltham and P. G. Fookes, 2005), the karst in construction site site#1 found between profile 1 and profile 6 is an older or complex karst type KIV, while the karst in construction site#2 found between profile 1 and profile 3 is a youthful karst type KII. Afterwards, the karst type changed over profile#5 to profile #6 to mature into karst type KIII. The karst in construction site#3, found between profile 1 and profile 3, is a youthful karst type KII. Then, the karsts change in profile 4 to an older, mature karst type KIII. The karsts found between profile #5 and profile#6 is of the older or complex karst type KIV. Early planning is needed to mitigate or minimize the risk of structures in these construction sites over karstified carbonate bedrock. Initial consolidation of geo grids, driven piles to rock head pinnacles, and control drainage works must be put into operation in these respective sites.
