Chengi a major river of Khagrachari district is getting polluted day by day due to unplanned river management. Both primary and secondary data have been used to conduct this work. Primary data have been collected through extensive field work, questionnaire and sample collection. Water samples have been collected from three sampling station, namely Ganjapara, Chengi Bridge and Rubber factory sites. Water temperature is higher at different sampling stations in the study site than Bangladesh standards (25°C) due to the direct hit of the sun. The maximum DO value is 5.8 mg/l at the sampling station one and the minimum is 5.3 mg/l at station three. So, it concluded that the DO value of the Chengi river is comparatively lower than the Bangladesh Standards. The water Temperature and pH is higher than the Bangladesh standards and the value of other parameters are very lower than the Bangladesh standards. In fish diversity, 10 families belonging to 6 orders were recorded and identified by the fin formula. The order Cypriniformes occupied 40%, the order Perciformes which occupies 25% and the order Beloniformes, Siluriformes, Cyprinodontiformes occupied 10% and Mollusks and other invertebrates occupied 25%, respectively in all cases. This work provides a complete picture of the water quality and also the fish diversity of the Chengi River. It will be helpful for water resource management and planning. Bangladesh J.

AbstractMadarsa education is very common among the Muslims in India. Hundreds of thousands of Muslim children acquire their primary, and perhaps the only, formal education in these madarsas with a cursory knowledge of modern education. As a result they are lagging behind in science education and their representation and participation in the scientific activity of the country is woefully low. As such they are unable to earn sufficiently to lead a comfortable life and provide proper leadership to their community to face the challenges of the modern world. The purpose of the present study is to analyse whether madarsa education becomes a barrier in promoting modern and higher education and secondly how far these institutions helped improve socio-economic conditions of madarsa trained persons in the District of Mewat (Haryana). In the absence of secondary data, the present study is based on the primary data collected through both extensive and intensive field work. A total of 2,350 households were surveyed and information regarding demographic, socio-economic and environmental conditions of these households was collected. Such a varied nature of data was assigned weightage according to their importance and finally the composite score was calculated to find out the levels of the socio-economic conditions of madarsa trained persons.

This article is about the agreement and consensus between government and rebellion groups during war politics with special reference to Ampara district in Sri Lanka. The article argues that war causes transforming normal pattern of politics if we perceive of war as power struggle. The article further argues that to understand politics and power struggle during war requires conceptualization of war politics. Therefore, this article has attempted to conceptualize war politics and applied it to understand the nature and content of war politics in Sri Lanka in general and in Ampara district in particular during the period of protracted civil war. The data for the study were collected from both primary and secondary sources. Primary data were extracted from the extensive field works while secondary data were collected from desk analysis. The above data were descriptively analyzed and presented in this paper as summaries of arguments and author’s interpretation. This study has found that war causes dual power making civilians and officers becoming clueless on whose orders were to be obeyed because war resulted in crisis of the state. The study has also found that war politics results in syndromes of incapacitated, establishment of dual power and existence of reciprocal understanding between government and rebellion groups during war. The study concludes that there is a probability of an emerging agreement and consensus between actors of governmental politics and war politics during wars to achieve their strategic objectives.

ABSTRACT This research aims to analyze the condition of seagrass ecosystem to see water quality data of the seagrass habitat and percentage cover of seagrass in the waters of the Pramuka Island, Seribu Islands. The research was conducted over two months from October to November 2014.This research used a descriptive method with field survey approach. The population in this study is the seagrass in Waters Pramuka Island. Determining the location with purposive sampling of the sampling is divided into three stations is North, East and South. Data collection techniques include primary data and secondary data. Primary data is data of seagrass (type, percentage cover and density of seagrass) and data of seagrass habitat environmental parameters (water temperature, current speed, brightness, depth, salinity, substrate, TSS, DO, pH) were obtained by direct measurement in the field, while secondary data include the general state of the research sites. Data analysis techniques used in this study using analysis of community structure of seagrass and water quality analysis. The results showed that seagrass species found in the Pramuka Island there are 6 types of seagrass Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halophila ovalis, Halodule uninervis, Thalassia hemprichii. Conditions of seagrass in the waters of the Pramuka Island included into the category of less healthy-poor seagrass. At station 1 percentage by 31% classified seagrass less healthy conditions, while the other two stations are stations 2 and 3 belong to the category of the poor condition of seagrass, with each percentage cover of seagrass 19.4% and 20.3%. Of all water quality parameters measured, all the parameters are still in normal circumstances, but there are some parameters whose value is high at some stations TSS and pH value is high at station 2 with a value of TSS 18 mg/l and a pH value of 8.2. Water quality and seagrass communities in station 1 is still in good condition for the growth of seagrass, because at this station is an unspoiled area away from human activity, while the stations 2 and 3 have undergone changes in community structure of seagrass because at this station has several anthropogenic activities that disrupt the lives of seagrass, mostly from human activities such as domestic sewage and hoarding/reclamation, which affects the condition of seagrass at station 2 and 3 are poor seagrass.

The data used for multivariate analysis and the method of primary data is storet direct measurement results (in-situ) sea water quality is Saleh Bay, Sumbawa district Nusa Tenggara Barat were taken on July 8-10 in 2012 at several stations. Analysis of water quality were conducted in a laboratory Environment IPB. Water sampling station parameters of Chemical Physics waters performed on five stations: station 1 taken on coastal areas; Station 2 is taken on the middle of the waters; Station 3 taken at the Mouth of the Bay area 1; station 4 taken on the Mouth of the Bay area 2; station 5 taken in outdoor areas. Based on the results of the analysis of the Storet against physical parameters of chemical and heavy metal waters Saleh Bay, Sumabawa obtained the value of final score totaled-30, this value indicates that the waters of the Gulf of Pious Sumbawa are on the status light polluted (Grade C). This calculation is calculation of the total for all stations, this was desebabkan sampling only do as much as one time. Parameters give the value of the score is negative physical parameters include temperature, chemical parameters i.e., i.e. the parameters of phosphate (PO4) and Total Organic Matter (TOM). From the results of the analysis of PCA looks there are two components that can represent the diversity of PC1 and PC2 total i.e., water quality parameters are dominant i.e. ammonia, nitrate, pb and temperature, in addition there are special characteristics in station 1 which is different with the other stations (score plot). There is a link between some physical chemical variables Saleh Bay waters of regression analysis. Seen that the relationship has the pb parameters very closely with other response i.e. ammonia, nitrate and temperature on the waters of Saleh Bay, with a value of R2 amounted to 96.6%.Keywords: grouper, PCA, Storet, Saleh Bay AbstrakPenelitian ini menjelaskan keterkaitan kondisi fisika dan kimia perairan teluk saleh dalam pemilihan lokasi untuk budidaya ikan  kerapu.
