Act No. 18 of 2008 on Waste Management mandate that the community or household is the beginning of the stage of waste management processes, which make waste separation. Up to know solid waste management in urban area is still a complex problem, either from social, management, or technology aspects. The other problem of solid waste management is due to the people behaviour, which is mostly still unaware. Community respondents do not wish to waste segregation and argued that the waste separation should be done by the government. Seen thatthe awareness for change in how to manage the waste is still low. Local governments still need to continue to disseminate the Act No. 18 of 2008 on Waste Management and provide motivation to the community or households that are willing to segregation waste at the source.Keywords : waste, waste separation, community perception of waste

Regional outonomy that is meant as right, authority and obligatory of the district (kabupaten/kota) to regulateand manage their own governance and community’s interests gave pressure impacts to the environmentalsustainability since its implementation in 2001. The spirit to utilize natural resources from the districtarea tend to explore the environment irresponsibly which resulted in degradation of the environmentalsustainability. The district policies had often not been assessed in detail before implementation especiallytheir impacts to the environment. This caused the regional autonomy went into a different direction,therefore it needs an improvement in the level of program determination, policy and regulation applied, sothat the spirit to conduct decentralised governance will be kept on the rules of sustainable developmentwhich is environmentally friendly.Key words : Sustainable Development, Regional Autonomy

Tulisan ini mencoba mengulas tentang adanya fenomena alam yang sangatlangka dan unik berupa gumuk pasir tipe "barchan", yang terbentuk sebagaiakibat adanya ekosistem Parangtritis yang khas. Pantai Parangtritis khususnya dan pantai selatan Yogyakarta umumnya saat ini telah berkembang sangat cepat di dalam pemanfaatan potensi sumber daya alam di lahan pesisir sehingga banyak pihak berkeinginan untuk memanfaatkan lahan pantai berbagai keperluan, sehingga mengancam keberadaan gumuk pasir. Dengan segala keunikan, karakteristik dan potensi pantai yang khas tersebut, maka potensi terjadinya konflik kepentingan antar sektor akan semakin besar. Gambaran konflik dan akibat yang akan ditimbulkan apabila terus dibiarkan dapat mengancam kelestarian gumuk pasir di Parangtritis tersebut. Dengan model sistem dinamik maka upaya untuk melestarikan keberadaan gumuk pasir dapat dimungkinkan melalui skenario pembangunan berkelanjutan yaitu menyeimbangkan atau mengendalikan laju pengurangan lahan dengan laju penambahan wilayah gumuk.

Sektor industri merupakan sektor yang sangat strategis untuk diandalkan dalam mendukung pertumbuhan ekonomi. Walaupun demikian dalam sisi lainsektor ini Ã‚Â memberikan kontribusi yang cukup signifikan terhadap permasalahan degradasi lingkungan dan penurunan sumberdaya alam (SDA). Untuk mencegah terjadinya pemanfaan SDA yang boros dan tidak efisien serta mengurangipotensi dampak lingkungan maka industridalam pengoperasiannyaperlu menerapkankonsep produksi bersih (clean production). Kota Probolinggo memiliki banyak industri keramik yang masih belum efisien dalam menggunakan sumber daya dalam proses produksinya. Oleh karena itu, penelitian tentang penerapan konsep Produksi Bersih di industri keramik Kota Probolinggo ini dilaksanakan dengan tujuan untukmengidentifikasikan jenis keluaran yang non-produk atau Non Product Output(NPO), upaya penanganan NPO dan memberikan rekomendasi prioritas penanganan NPO tersebut dalam upaya peningkatan efisiensi produksi, penurunan tingkat pencemaran serta penurunan biaya produksi.Mengingat industri keramik merupakan industri yang berbasis pada penggunaan energi (energy intensive based industry) maka upaya peningkatan suhu pembakaran untuk mengurangi produk yang tidak sesuai (unspecification products)akan memberikan dampak pada penurunan limbah yang keluar.Selain itu,penggantian lampu biasa dengan lampu hemat energisertapemasangan meteran listrik (alat ukur konsumsi listrik) pada setiap peralatan produksi dapat memberikan informasi bagi manajemen dalam mengambil keputusan terkait dengan penghematan.Berdasarkan data empiris, potensi penghematan yang dapat dilakukan dengan penerapan konsep produksi bersih ini berkisar antara 10% dan 30% dari biaya produksi.Kata Kunci: Produksi Bersih, Non Product Output,Sustainable Resource Management
