Tujuan penelitian untuk mengetahui kualitas fisiko kimia air sungai Kaligarang dan kandungan logam berat pada ikan mas dan ikan nila yang hidup di sungai tersebut. Penelitian ini merupakan penelitian eksperimen lapangan, menggunakan Karamba Jaring Apung. Parameter fisiko-kimia yang diukur adalah suhu, pH, DO, alkalinitas, kesadahan, kecerahan dan kecepatan arus serta kandungan logam berat di air sungai, menggunakan metode Atomic Absorption Spectrophotometry (AAS). Kadar logam berat Cd, Pb dan Hg juga dianalisis pada ikan mas dan ikan nila Hasil penelitian menunjukkan bahwa suhu, pH, DO, alkalinitas, kesadahan, kecerahan dan kecepatan arus masih berada dalam kisaran yang layak bagi kehidupan ikan. Kadar Cd, Pb dan Hg di perairan masing-masing adalah sebesar 0,006 mg/L, 0,01 mg/L dan 0,0006 mg/L. Kadar Cd, Pb dan Hg pada hati ikan nila berturut-turut 0,000407 mg/kg, 0,000812 mg/kg dan 0,000575 mg/kg, sedangkan pada ikan mas 0,000307 mg/kg, 0,000269 mg/kg dan 0,000349 mg/kg. Kesimpulan; air sungai Kaligarang terkontaminasi logam berat Cd, Pb dan Hg dan ikan yang hidup di sungai tersebut telah mengakumulasikan ketiga logam berat tadi.The aim of this study is to determine the quality of water in Kaligarang based on the physicochemical characteristics and heavy metal content in carp and tilapia fish live in the river. This study is a field experiment, by using Karamba floating net; the fish were caught and maintained. The physicochemical parameters of the water measured were temperature, pH, oxygen, alkalinity, hardness and brightness, speed of the flow and content of heavy metals. The heavy metal content was measured using Atomic Absorption Spectrophotometry (AAS). Levels of heavy metals (Cd, Pb and Hg) were also analyzed in carp and tilapia. The results showed that temperature, pH, oxygen, alkalinity, hardness, brightness and speed of the flow were still within the appropriate range for the life of the fish. Levels of Cd, Pb and Hg in water were amounted to 0.006 mg/L, 0.01 mg/L and 0.0006 mg/L, respectively. Surprisingly, the levels of Cd, Pb and Hg in liver of tilapia were 0.000407 mg/kg, 0.000812 mg/kg and 0.000575 mg/kg, respectively, whereas in carp were 0.000307 mg/kg, 0.000269 mg/kg and 0.000349 mg/kg, respectively. It can be concluded that, Kaligarang River was contaminated with heavy metals Cd, Pb and Hg. This contamination leads to the accumulation of heavy metals in fish that live in the river.

Natural Science is the study of the phenomenon that occurs in the student environment. Directly oriented learning in the student environment makes learning meaningful because students can see the real object being studied. Based on the observations in SMP Negeri 5 Pekalongan, learning activity has not utilized the environment as a learning source. Whereas the location of the school near the appropriate learning sources to study environmental pollution material. Student learning outcomes are less than optimal and students tend to be passive. Therefore, variations are made in the learning by utilizing the Kalibanger River as a source of learning environmental about environment pollution. The method used in this research is quasi experimental design type nonequivalent control group design. Determination of the sample is done by purposive sampling technique and used as experimental class is class VII F and control class is class VII D. Student retrieval data using test instrument, while student activity is taken from observation sheet and questionnaire. Learning result data obtained by posttest value is higher than pretest. Increased learning results occur due to learning activities undertaken by students. Recapitulation of experimental class student activity is 87,9% which belong to very active criteria. Based on the results of t-test calculation obtained t-count = 3.323> 2.040 so H1 accepted, it can be concluded learning Kalibanger river utilization as a source of learning about environmental pollution can increase the activity and learning outcomes of students of SMP Negeri 5 Pekalongan.

Laboratory activities and environment utilization around Madrasah Aliyah (MA) Salafiyah Pati Central Java has not been done completely in biology learning.  As a result, student learning outcomes are less than optimal. The problem is predicted by Window Shopping (WS) learning model and the surrounding nature roaming approach (JAS) as an alternative learning. The purpose of this research is to analyze the effectiveness of WS learning model and JAS approach on ecosystem material in MA Salafiyah Pati Central of Java. This type of research is Quasy Experimental using Pretest-Postetst Design. The population was nine class of X. The sampling was XE class (control), XF (WS accompanied by JAS), and XG (JAS). Samples were taken using purposive sampling technique. The research variables are cognitive learning outcomes, affectiveand psychomotor. Class of WS and JAS of  N-gain is high category, the highest grade average grade and  percentage of classical completeness higest. All classes get affective and psychomotor value with very good criteria. Based on these result can be concluded that use of learning models WS and JAS on ecosystem materials in MA Salafiyah Pati Central of Java effectively improve student learning outcomes.

Biosorption is a new waste treatment technology that can eliminate toxic heavy metals. Biosorption can be considered as an environmentally friendly alternative technology to treat industrial liquid waste that is economically proper to use. One of them is biosorption that utilizes the microorganisms’ absorption ability, especially bacteria that can absorb heavy metals in waters, such as Enterobacter agglomerans. This research aimed to determine the ability of E. agglomerans in reducing heavy metals pollution in local river. The research employed the measurement of the effect of lead (Pb) to E. agglomerans growth using Optical Density (OD) at wavelength 600 nm. The colony numbers were calculated using a standard curve. While the ability of E. agglomerans to reduce heavy metals concentration in liquid media was measured using AAS with a wavelength of 240 nm. The results showed that lead affected the growth of E. agglomerans. The OD value has a negative relationship with the concentration level of Pb. The ODs were decreased from 2.867 to 1.242, using Pb level from 0 ppm to 20 ppm. Therefore, it proved that E. agglomerans could reduce heavy metals concentration in local river in Central Java Province. This research was the first report on E. agglomerans activity on heavy metal in contaminated water. This result can be used as a reference for industrial sites near the river to treat their wastewater before discharging it to the river body to preserve its water purity.
