"Annual export-import traffic in live-reef-fish commerce in Asia was confirmed not less than 25,000 tons caught using tons of cyanides. This was not included domestic consumption and deadfishes caused by cyanides. This condition clearly menaces the conversation of coral reef ecosystems and its related biota especially in Indonesia where utilization of 'potas' is growing. By environmental law set up since 1982, this kind of commerce is illegal. Legal matters on this issue became difficult to pursue because physical evidence required to determine whether an action or transaction was against the law or not oftenly difficult to prove. The police is usually faced with fish samples or other marine animals exposed to cyanides and to determine cyanide concentration, a sensitive, reliable and accurate method is needed even down to ppb level. The development of such method is urgently required for two reasons. First, the large and unique Indonesia must have handling system that is able to manage natural conservation process appropriately. Rapid sampling and analysis in the field as well as preparation of human resource in modern analytical proficiency are examples of the problems. Secondly, it may help law practitioners in providing them some scientific physical evidence for legal cases especially in marine environment protection. It is concluded that the role of marine analytical chemistry is very decisive in marine science development as well as in law enforcement."

"A unique approach to the chemistry of water, this textbook by top environmental author Stanley Manahan focuses on water as a renewable resource from a green chemistry and sustainability perspective."

"Tesis ini membahas tentang penilaian kualitas perairan dalam upaya pengendalian pencemaran di wilayah pesisir kota pekalongan. Pada umumnya wilayah pesisir Kota Pekalongan digunakan oleh masyarakat sebagai lahan budidaya pertambakan, namun karena kondisi perairan yang keruh dan telah tercemar oleh beberapa bahan pencemar, kegiatan budidaya menjadi tidak maksimal dilakukan. Informasi terkini tentang kondisi karakteristik fisika, kimia dan biologi di perairan Kota Pekalongan dianggap masih terbatas. Oleh karena itu, diperlukan ketersediaan data parameter perairan di Kota Pekalongan. Penelitian dilakukan pada bulan September 2012 yang ditetapkan secara purposive, berdasarkan baku mutu lingkungan yang telah ditetapkan pemerintah (KepMen KLH No.51/men-KLH/2004). Berdsarkan nilai TSS, TDS, DO, total fosfat, dan NH3 yang dibandingkan dengan baku mutu lingkungan dalam KepMen KLH No.51/men-KLH/2004, wilayah laut pesisir Kota Pekalongan sudah tercemar. Total beban cemaran tertinggi di muara sungai adalah TSS sebesar 8,317,79 mg/L. Adapun alternatif upaya yang perlu dilakukan adalah pengendalian pertumbuhan penduduk, penerapan teknologi melaui penerapan konsep 3R (reduce, reuse, recycle), pembangunan Instalasi Pengolahan Air Limbah (IPAL) serta mengupayakan keberlanjutan pengelolaan sampah terpadu berbasis masyarakat.

The focus of this study is water quality assessment on control pollution effort in coastal areas of Pekalongan District. Generally, coastal areas of Pekalongan District was used as ponds culture, but as its waters condition and has been pollution by certain contaminant materials, its land culture activity has decreased and not maximally utilized. Recent information on physical, chemical and biological characteristic condition around Pekalongan District waters is limited. Therefore, parameter data availability was needed. Research was conducted in September 2012, which was determined as purposive, based on environmental quality standard enacted by government (Ministry of Environment Ministerial Decree No. 51/MEN-KLH/2004). Based on TSS, TDS, DO, phosphate total, and NH3 compared with environment quality standard in Ministry of Environment Ministerial Decree No. 51/MEN-KLH/2004, it realized that coastal areas of Pekalongan District were in polluted condition. Highest contaminant load total in outfall was TSS as amount 8,317,79 mg/L. Another alternative effort worth to be conducted is population growth control, applied technology based on 3R concept (reduce, reuse, recycle), Waste Water Plant, and conducting integrated communal solid waste management sustainability."
