Abstract

Banjir tanggal 11 Februari 2002 mengejutkan banyak pihak karenadatangnya tiba-tiba dan tidak terduga besarnya, sehingga hampir 30% wilayah Jakarta tergenang air , transportasi lumpuh , dan memakan korban jiwa akibat tanah lingsor, tenggelam, hanyut dan tersengat aliran listrik. Total aliran air permukaan diperkirakan mencapai 70 juta meter kubik, dimana jumlah tersebut tidak dapat tertampung oleh badan-badan sungai yang ada dan meluap menggenangi daerah dataran banjir sungai (floodplain area) yang saat ini banyak ditempati oleh pemukiman penduduk. Berdasarkan hasil studi yang dilakukan oleh Kelompok Pengkajian Sitem Pengelolaan Air (BPPT) dalam Studi Studi Model Optimisasi Pengelolaan Air Tanah Jakarta, maka besarnya imbuhan buatan yang harus dimasukkan kembali kedalam akuifer dangkal untuk daerah seluas 25 km2 berkisar antara 1.082.419- 54.120.960 m3/tahun atau antara 1,08 - 54,12 m3/tahun/m2. Lokasi imbuhan buatan dapat dilihat pada Peta Lokasi Imbuhan Buatan Berdasarkan Hasil Optimisasi Pengelolaan Air Tanah. Jika diasumsikan 1 (satu) sumur resapan dengan diameter 0,8 meter, lebar bidang resapan 1 meter pada tanah dengan permeabilitas rendah (0,00105 m/hari), maka kapasitas sumur resapan adalah 0,592 m3/tahun/unit. Dengan demikian untuk daerah Jakarta dan sekitarnya dibutuhkan kurang lebih 2 juta sumur resapan. Pelestarian lingkungan merupakan tanggung jawab pemerintah dan masyarakat. Walaupun sudah ada Surat Keputusan GubernurDKI yang mengatur tentang sumur resapan, pelaksanaan dilapangan masihsulit pengawasannya. Dalam kondisi krismon ini perlu langkah terobosan untuk membuat sumur resapan dengan program jaring pengaman sosial, dengan demikian pemerintah membuka lapangan pekerjaan bersamaan dengan perbaikan lingkungan.

Abstract

Sejauhmana masyarakat, termasuk industri menggunakan teknologi lingkungan yang tersedia terkait erat dengan tingkat kesadaran dan kepedulian (awareness) masyarakat terhadap lingkungan. Salah satu penyebab keterbatasan penggunaan teknologi lingkungan di Indonesia saat ini adalah pengetahuan dan kepedulian masyarakat (public awareness) terhadap lingkungan yang masih sangat kurang. Oleh sebab itu, penyediaan teknologi lingkungan perlu didukung oleh penyelenggaraan pendidikan lingkungan secara intesif. Demikian pula dalam proses terjadinya perubahan pola perlakuan masyarakat terhadap lingkunga sebagai dampak kenerhasilan penyelenggaraan pendidikan lingkungan, maka diperlukan dukungan ketersediaan teknologi lingkungan yang dibutuhkan untuk melakukan tindakan-tindakan penyelesaian masalah lingkungan yang dihadapi. Terbentuknya keterkaitan antara kedua aspek tersebut diharapkan dapat memebrikan kontribusi yang berarti dalam mewujudkan pembangunan yang berwawasan lingkungan dan berkelanjutan. Pembahasan berikut merupakan ulasan berdasarkan referensi dan pengamatan kondisi penyediaan teknologi lingkungan dan pendidikan lingkungan di Indonesia saat ini.

Abstract

Sebagian besar sumber daya lahan di Indonesia merupakan lahan kering yang memiliki potensi untuk usaha pertanian. Pada umumnya kawasan lahan kering tersebut memiliki topografi dari landai sampai terjal, sehingga apabila dimanfaatkan untuk usahatani sangat rentan terhadap erosi. Tingkat erosi yang tinggi merupakan masalah serius terhadap kelestarian sumberdaya lahan di Daerah Aliran Sungai (DAS) dibagian hulu, dan menimbulkan pengaruh negatif di DAS bagian hilir.Usahatani pada lahan kering menghadapi problema yang sangat kompleks,beragam dan beresiko tinggi, oleh karena itu diperlukan penelitian dengan strategi pendekatan pengelolaan secara terpadu. Penelitian dan pengembangannya melibatkan berbagai disimplin ilmu (interdisipliner). institusi (interinstitusi) dan petani sebagai pengelola utamanya.Pengembangan sistem usaha tani konservasi terpadu pada sub DAS Prambanan hulu dengan tujuan mencari solusi pengembangan teknologi alternatif serta upaya mengendalikan erosi, ternyata telah mendapat respon positif baik oleh petani binaan maupun non-binaan.

Abstract

In attempt to know the trophic status and phytoplankton community in Juandareservoir this research was conducted. This research revealed that based onsecchi disk and concentration of Chlorophyll-a the Juanda reservoir have become eutrophic, with phytoplankton density was about 27,779-43,439 x 10-3 cell/l. The phytoplankton community was dominated by Synedra sp. (22.4-33.8%) and Microcystis sp. (10.2 –31.4 %;). However this result was about 1000 x bigger than previous publication which reported the phytoplankton density in Juanda reservoir was only about 621- 35,514 cell/l, and the phytoplankton community was dominated by Microcystis sp. which always > 85%. These differences were suggested due to using net-plankton in the sampling of phytoplankton.

Abstract

Integrated watershed management, which aims at restoration of a soundhydrologic regime in the watershed considering water resources utilization,appropriate landuse, water quality control and environmental conservation, is becoming crucially important in Indonesia. Because, the land degradation of watershed in Indonesia more increases every time. There is a growing concern that many parts of the Indonesia watershed will continue to face problems of watershed degradation. The basic problem in most watershed area, especially in Java, is too many people being concentrated on too small land base. Besides that, the causes of watershed degradation are complex and interrelated, such as too much emphasis being placed on economic growth in the management of natural resources, and the continuing presence of poverty, population growth, infrastructural and industrial development. Thus, the exisiting environmental problems and their overall impacts are not only biophysical in nature, but also social.The integrated watershed approach stresses the interaction of all activities that take place throughout the watershed. The strategy of watershed management approach uses new paradigm with people of participation and using community development in operational, practices and bottom up approach.

Abstract

Anaerobic fixed bed reactor is a fermentation anaerobic reactor used microorganism attached growth system, where degradation of organic material done by microorganism that growth in support material as fixed film. This system mostly used for organic wastewater treatment now. The assessment is carried out for the Slaughterhouse wastewater treatmentwhere the support material for microorganism growth is a fabricated media. Plant is a demonstration scale by digester volume of 600 m . Wastewater is feeding to the digester by up flow system. The wastewater pumped from the bottom of the digester, flow through the support material, contact with the microorganism fixed on the media. Degradation of the organic waste process is take place along wastewater contact with the fixed film.Observation is on the performance of the reactor by the influence of organic loading to the pollution degradation of slaughterhouse wastewater called reactor efficiency. Fixed Bed Reactor performance still reached until 3 days hydraulic retention on organic loading rate about 3.05 kg COD/m hr, and efficiency 75 %.
