IDENTIFIKASI PEMANFAATAN DAERAH SEMPADAN SUNGAI TUKAD BADUNG
Get PDFSungai merupakan jaringan pengaliran air yang dibatasi oleh garis sempadan. Sempadan sungai merupakan kawasan yang berfungsi sebagai penyangga agar fungsi sungai dan kegiatan manusia tidak saling mengganggu. Tukad Badung adalah salah satu sungai yang melintasi Kota Denpasar yang memiliki fungsi sebagai sumber air irigasi dan saluran pembuangan. Untuk mengetahui fungsi dan pemanfaatan daerah sempadan Tukad Badung dilaksanakan kegiatan identifikasi pemanfaatan daerah sempadan sungai di sepanjang Tukad Badung dengan melakukan kajian dari berbagai literature yang terkait. Dengan dilakukannya identifikasi pemanfaatan daerah sempadan sungai diharapkan mampu memberikan gambaran tentang kondisi sempadan sungai, sehingga dapat dipergunakan sebagai dasar dalam menentukan langkah penataan dan pengelolaan wilayah sungai Tukad Badung. Hasil identifikasi menunjukkan bahwa pemanfatan lahan sempadan sungai Tukad Badung terdiri dari permukiman (79%), sawah (11%), tegalan/tanah (8%) dan tempat ibadah/pura (2%). Hasil ini menunjukkan bahwa telah terjadi ketidaksesuaian pemanfaatan terhadap daerah sempadan sungai di Tukad Badung dimana yang seharusnya merupakan daerah kosong yang berfungsi sebagai penyangga dan pengendali banjir tetapi dimanfaatkan sebagai permukiman. Hal inilah yang dapat menimbulkan permasalahan lingkungan seperti menurunnya kualitas air sungai, terjadinya penumpukan sampah yang dapat menyebabkan terjadinya banjir dan ganguan kesehatan
PERANAN EFFECTIVE MICROORGANISM 4 (EM-4) DALAM PENGELOLAAN SAMPAH TINJAUAN DARI PERSPEKTIF PENGELOLAAN LINGKUNGAN SECARA BERKELANJUTAN
Get PDFSampah yang tidak dikelola dengan baik akan menyebabkan pencemaran lingkungan yang membahayakan kesehatan manusia oleh karena itu sampah perlu dikelola dengan cara yang effektif, murah dan berwawasan lingkungan. Beberapa hasil penelitian menunjukan bahwa Effective Microorganisms 4 (EM-4) dapat digunakan sebagai dekomposer sampah organik menjadi kompos. EM-4 merupakan kultur campuran dalam medium cair berwama coklat kekuningan, berbau asam dan terdiri dari mikroorganisme yang men guntungkan bagi kesuburan tanah. Adapun jenis mikroorganisme yang berada dalam EM-4 antara lain : Lactobacillus sp., Yeast-Saccharomyces, Actinomycetes, Streptomyces. Penggunaan EM-4 sebagai dekomposer sampah selain bermanfaat dan mempunyai keunggulan sebagaimana disebutkan diatas, juga mempercepat waktu yang dibutuhkan untuk membuat kompos dibandingkan dengan cara konvensional. Waktu yang singkat berarti juga merupakan penghematan sumberdaya yang dibutuhkan untuk pengelola sampah menjadi kompos. Namun demikian penggunaa teknologi EM-4 untuk pengelolaan sampah diperkotaan yang berwawasan lingkungan belum memasyarakat
VERIFICATION OF HOURLY GSMAP RAINFALL ESTIMATES DURING THE FLOOD EVENTS IN KUMAMOTO PREFECTURE, JAPAN
Get PDFJapan and other countries have been greatly damaged by floods in the past due to heavy rainfall. Flood forecasting using rainfall data observed by satellite is a welcome development. GSMaP (Global Satellite Mapping Precipitation) data can present the amounts of rainfall with high temporal resolution. For that reason, it is important to measure the accuracy of hourly GSMaP data. Kumamoto Prefecture was chosen as the research location in this study. The aim of this research was to verify hourly GSMaP data in two type file (i.e., GSMaP_MVK and GSMaP_NRT) with rain gauge data and to define the rainfall pattern which causes flood. Verification of hourly rainfall data showed that GSMaP_MVK was reasonably good at detecting precipitation events and GSMaP_NRT was inadequate to represent the rainfall data. Two rainfall patterns were observed over Kumamoto Prefecture before the occurrence of the flood
Pemanfaatan dan Penggunaan Tanah Perspektif Hukum Investasi Berwawasan Lingkungan Untuk Kemakmuran
Get PDFThe arrangement of legal certainty of land use in investment, is done by issuing HGU, HGB or HP with a limited period of time and may be extended or renewed. However, legal uncertainty may occur when the concession period of HGU, HGB, or HP expires but the application for extension or renewal is not accepted rejected) so that the land, by- the laws, is controlled by the state. This brings about juridical impact that the productive ongoing company should be relocated or even closed so that it is clearly incompatible with the principle of sustainable investment and welfare of the people. Land use with HGU, HGB, or HP in Eco- Investment for the prosperity of the people should be based on integrated land use management with spatial planning (RTRW) of the regency / city government by determining the investment activity zone within the framework of a national land policy
