Abstract

Penelitian ini dilakukan pada kondisi musim kemarau (Agustus 2003, monsun Timur), dan pada kondisi musim hujan (Maret 2004, kondisi monsun Barat), pada tiga kondisi lingkungan, yaitu: sungai dan muara Sungai Demaan, dan perairan pantai Kartini Jepara. Pengukuran beberapa parameter kualitas air dan pengambilan sampel air dilakukan pada 12 stasion. Dengan menggunakan metoda Indeks Pencemaran (pollution indexs) diketahui bahwa indeks pencemaran pada kondisi musim kemarau mempunyai nilai yang lebih tinggi dari pada kondisi musim hujan, baik di lingkungan sungai, muara, naupun perairan pantai. Kondisi lingkungan sungai pada kondisi musim kemarau mempunyai kriteria pencemaran cemar berat, dengan IP 11,48, pada kondisi musim hujan menjadi cemar ringan, dengan IP 4,49. Pada kondisi lingkungan muara saat musim kemarau, termasuk cemar sedang dengan IP 6,71, sedangkan pada kondisi musim hujan menjadi cemar ringan, dengan IP menjadi 3,11. Status mutu air di perairan pantai ke arah laut hingga stasiun kontrol termasuk dalam cemar ringan, baik pada kondisi musim kemarau maupun kondisi musim hujan. Secara umum pola penyebaran Indeks Pencemaran pada monsun Timur dan monsun Barat, mempunyai pola yang relatif tinggi di sekitar muara dan menurun dengan meningkatnya jarak dari muara, dan tersebar mengikuti dinamikaperairan ke Selatan, kemudian ke Baratdaya mengikuti bentuk pantai Teluk Kartini.Kata kunci: indeks pencemaran, monsun, muara, perairan pantai, sungaiThis research was conducted on the condition of dry season (August 2003, East monsoon), and the condition of wet season (March 2004, West monsoon), on three environmental conditions: river and river mouth ofDemaan River, and Kartini coastal waters, Jepara. Measurement of several water quality parameters and collecting of water samples was carried out at 12 stations. By using Pollution Index method, it could be recognized that pollution indexes (PI) in the river, river mouth, and coastal waters during dry season were higher than during wet season. In the river environment during dry season was heavy polluted with PI 11.48,and during wet season became light polluted with PI 4.49. River mouth environment during dry season was fairly polluted with PI 6.71, and during wet season became light polluted with PI 3.11. The status waterquality of coastal water to the sea direction until control station was in light polluted, both in dry and wet seasons. In general, the pattern distribution of PI in East and West monsoon were relatively higher around theriver mouth and decreased with increasing of distance from the river mouth, and distributed by dynamic of waters to the South, and then to the Southwest went along the coast of Kartini Bay.Key words: pollution index, monsoon, river mouth, coastal waters, river.

Abstract

The development of science and technology has brought great influence to educational technology which further influences learning technology and ultimately to the patterns of learning from conventional/ traditional (textual and teacher only learning) patterns to transition patterns (semi textual and teacher together media) and finally to modern patterns (contextual and media as learning resources). This is very influential on the pattern of learning Civic that is conventional/traditional textual to contextual learning patterns. The current reality in Indonesia is that civic learning is still dominated by conventional systems, so that the application of contextualized oriented learning is still far from expectations, as evidenced by the still serious learning problem, where most students can not relate what they have learned and applications in his current and future life. This occurs because the lesson of civics is less related to the material with the reality of student life, not contextual, consequently civics fails in carrying out its mission to develop civics competence namely civics knowledge, civics disposition and citizenship skills. In carrying the contextualized oriented civics learning, conventional learning system in schools is increasingly believed to be a system that is not effective anymore and resulted in learning Civics felt less meaningful for students To solve the problem of learning civics less meaningful, it is necessary to use contextual teaching approach learning) as one effective alternative. The application of contextual learning is an urgent need to solve the civic problems.DOI: 10.17977/um022v3i12018p001
