Abstract

Mangrove di kawasan Desa Banyuurip, Kecamatan Ujungpangkah Kabupaten Gresik Jawa Timur merupakan hasil penanaman oleh warga sekitar yang saat ini menjadi basis aktivitas jasa lingkungan, perikanan, dan pariwisata bahari serta memberikan nilai estetik tersendiri. Fokus penelitian ini adalah identifikasi mangrove dan penilaian total ekonomi mangrove di Desa Banyuurip Kecamatan Ujungpangkah Kabupaten Gresik. Metode pengukuran dan pengambilan data vegetasi mangrove menggunakan metode garis lurus atau transek garis. Nilai ekonomi total dilakukan dengan cara wawancara untuk memperkirakan nilai ekonomi hutan mangrove berupa manfaat langsung, tidak langsung, pilihan, dan keberadaan. Jenis mangrove yang mendominasi di wilayah pesisir Desa Banyuurip yaitu jenis Avicenia marina dengan kerapatan dan tutupan yang baik. Jenis lain yang ditemukan adalah Rhizopora mucronata, Bruguiera silindrica, dan Rhizopora apiculata. Nilai ekonomi total mangrove di wilayah pesisir Desa Banyuurip yaitu Rp. 21.423.890.000,00 yang diperoleh dari (1) manfaat langsung penangkapan kepiting sebesar Rp.1.836.480.000,00, kerang sebesar Rp. 18.534.720.000,00, dan tambak ikan bandeng sebesar Rp. 34.200.000,00; (2) nilai guna tak langsung yang dihitung sebagai penahan abrasi sebesar Rp. 315.353.520,00 per tahun; (3) manfaat pilihan (nilai biodiversitas) sebesar Rp. 1.057.500,00 per tahun; dan (4) nilai keberadaan dari ekosistem mangrove sebesar Rp. 182.400.000,00.

Abstract

Tingginya kepadatan trafik di pelabuhan Tanjung Perak Surabaya dapat menimbulkan masalah baru yaitu peningkatan kapasitas pengisian minyak solar pada kapal sehingga mengakibatkan volume buangan yang mengandung minyak (oily waste) cenderung meningkat. Alternatif penanggulangan secara tepat dan tidak menganggu lingkungan yaitu dengan cara menggunakan bakteri yang mampu mendegradasi minyak solar. Tujuan dari penelitian ini untuk mengetahui bakteri yang berpotensi mendegradasi minyak solar di pelabuhan Tanjung Perak dan dapat mengetahui kemampuan isolat bakteri tersebut dalam mendegradasi minyak solar. Penelitian ini menggunakan metode purposive sampling pada pengambilan sampel air laut dan menggunakan metode observasi di laboratorium untuk isolasi bakteri pendegradasi minyak, karakterisasi pengamatan bakteri, dan uji biodegradasi minyak solar. Hasil penelitian menunjukkan bahwa pada perairan pelabuhan Tanjung Perak diperoleh tujuh isolat bakteri pendegradasi minyak solar. Lima isolat terdapat pada Stasiun 1, area dimana potensi pencemaran minyak solar lebih tinggi, yaitu genus Pseudomonas, Bacillus, Klebsiella, Enterobacter, dan Citrobacter. Dua isolat lainnya yaitu genus Bacillus dan Klebsiella diperoleh dari Stasiun 2. Hasil identifikasi bakteri yang mampu mendegradasi minyak solar secara signifikan adalah konsorsium (isolat campuran pada genus Pseudomonas, Bacillus, Klebsiella, Enterobacter dan Citrobacter) dengan persentase biodegradasi sebesar 94,57%. Pada isolat tunggal, pada Stasiun 1 yang memiliki persentase biodegradasi tertinggi adalah genus Pseudomonas dan Bacillus dengan persentase biodegradasi masing – masing sebesar 91,94 % dan 89,99%. Pada Stasiun 2, bakteri pendegradasi yang memiliki persentase tertinggi adalah genus Bacillus dengan persentase 88,61 %.

Abstract

Gresik Regency is one of the industrial development areas in East Java Province due to its strategic location. This region has the opportunity to actively integrate the ecosystem into development planning. Management of integrated coastal areas is widely advocated at all levels of government as a means of delivering sustainable development in coastal areas. This study was conducted to determine the level of impact caused by each activity cumulatively on coastal and marine ecosystems in Gresik Regency. In general, this study is oriented towards collecting data of marine pollution level from various substances and sources, as well as changes over time in the status of the marine environment in Gresik Regency. The results showed that the increase in population growth accompanied by an increase in the amount of waste, as well as an increase in industry, port and agricultural activities in coastal areas of Gresik Regency require special attention in the management of the coastal and marine environment in Gresik Regency. The use of coastal and marine areas of Gresik Regency can lead to loss of biodiversity, as well as decreased stability and resilience of ecosystems in coastal and marine areas. It is necessary to take into account the pressures and impacts due to activities in coastal and marine areas and then propose the most appropriate development solutions within the framework of Integrated Coastal Zone Management in Gresik Regency.

Abstract

Environmental pollution is not a new problem in the Kenjeran, Surabaya coastal area. There are numerous studies show that these waters have been polluted. However, there is no specific study on the economic valuation of environmental impacts due to pollution that occurs in the area. The purpose of this study was to estimate the costs incurred from pollution that occurred in the Kenjeran coastal area. The estimation of the cost of pollution is done by calculating the decrease in fishery productivity and the tourism sector, and the increase in health and water treatment costs. Data collection techniques were carried out through secondary data collection, interviews, questionnaires, field surveys, and focused group discussions. The calculation results show that the costs incurred from pollution that occur in the coastal area of Kenjeran are Rp. 452,724,903,588,63 include (1) a decrease in fishery productivity in the form of lost fisherman income of Rp. 28,728,000,000.00; (2) a decrease in the tourism sector by Rp. 27,728,112,300.00; (3) the increase in health costs includes the cost of carcinogenic risk of Rp. 363,626,479,099.79 and gastroenteritis of Rp. 32,552,893,425.42; and (4) an increase in the cost of water treatment by Rp. 89,418,763.42. This effort is needed to remind policy makers of the importance of paying attention to the impacts arising from an activity on the environment and society as well as to show that environmental aspects are an important potential for long-term sustainable development activities and not as an obstacle to development.
