Kerangka kerja peraturan reklamasi dan pasca tambang di Indonesia menetapkan berbagai persyaratan untuk melaksanakan kegiatan reklamasi dan pasca tambang. Sebagai langkah awal, para pemangku kepentingan diwajibkan untuk berkonsultasi secara detail tentang peraturan-peraturan yang berlaku. Reklamasi timah alluvial (dan kemungkinan endapan logam alluvial lainnya) merupakan masalah yang pelik dalam mewujudkan program reklamasi pasca tambang yang berkelanjutan. Sering kali program reklamasi gagal karena adanya proses penambangan kembali di lahan yang sudah direklamasi. Masalah utama dalam proses reklamasi timah alluvial adalah bahaya geologi, hidrologi, hidrogeologi dan penambangan kembali. Dengan adanya data-data yang baik maka akan dapat dilakukan rekayasa teknik yang baik untuk mewujudkan  reklamasi yang berkelanjutan. Penerapan teknologi tepat guna untuk mengantisipasi bahaya geologi, hidrogeologi, hidrologi serta monitoringnya sehingga aspek yang akan mengurangi keberhasilan program reklamasi sudah dapat diantisipasi sejak awal sehingga program pencegahannya dapat dilakukan sejak dini. Proses sterilisasi yang baik dilakukan sejak awal proses penambangan ataupun dilakukan sebelum proses penutupan tambang agar proses reklamasi dapat berjalan secara berkelanjutan.

Vision is the science that informs us about the biological and evolutionary algorithms that our eyes, opticnerves and brains have chosen over time to see. This article is an attempt to solve the problem of colour to grey conversion, by borrowing ideas from vision science. We introduce an algorithm that measures contrast along the opponent colour directions and use the results to combine a three dimensional colour space into a grey. The results indicate that the proposed algorithm competes with the state of art algorithms.

AbstractA workshop on problems related to the analysis of nicotine and nicotine metabolites in body fluids at levels pertinent to the human situation was held in November 1974 in Stockholm. It was organized by C. Enzell, B. Holmstedt and A. Pilotti at the request of the Medical Advisory Board of the Swedish Tobacco Company. The goal of the workshop was to summarize the present state of art in the area outlined by the organizers and to discuss critically the advantages and limitations of the different analytical methods available today. EIeven experts in the field of metabolism, detection and biosynthesis of nicotine and related compounds were therefore invited to present papers on these topics and to participate in the discussions. AIl speakers invited were able to attend and the papers were arranged in the following groups:Each speaker had one hour and a half at his disposal which included the discussion which, due to the informal atmosphere and the smaII number of participants, was very lively and fruitful. The papers read at this workshop comprise a very valuable coverage of recent research in the fields of metabolism of nicotine and minor tobacco alkaloids, and of the various methods available for detection of these alkaloids. The abstracts are given below, while full papers, now edited by A. Pilotti, can be obtained on request from C. Enzell of the Swedish Tobacco Company
