Abstract

Solid waste management is a system involving all subsystems of management such as institutional, law, financing, operational, and community participation. Waste law which shelters the solid waste management is the umbrella of all local regulation (Perda). But in fact, its implementation and aplication have not run well as expected. Using a simple analisys method from personal experience as an Adipura award appraiser, thewriter tried to reveal the strengths and weaknesses in waste management all this time. The result shows that local governments, in general, haven’t considered the wastemanagement subsystems integratedly in handling the municipal garbage. They usually see the problem partially, not as an integrated system which includes all the subsystems. Municipal waste management should not become a proses which is independent fromthe other subsystems. It is recommended that the head of regional government see the waste management.

Abstract

This study was carried out to describe the characteristics of hypoxia in the tropical coastal sea. The general oceanographic surveys were conducted two times in Hurun Bay, 5-7 February and 17-19 February, 2003. And also, a day-night survey (25 hours survey) and the continuous monitoring of water temperature, current and meteorology were carried out. The monitoringdata of water temperature indicated that the seasonal variation and the spatial in temperature in Hurun Bay were small. The difference in temperature between the surface and bottom water was less than 1.3 oC. The water temperature increased from February and the highest in April.It gradually decreased to late June and a sudden decrease occurred in the early July. The lowest temperature was observed in September and then it increased again. The seasonal variation in the thermal stratification was not happened. Instead of the weak thermal stratification, a sharp picnocline was formed around 20m in the dry season. The water below the picnoline was colder and more saline and contained less DO than the overlaying water. The cold water mass which has high salinity and lower DO was situated along bottom deeper than 20m on 17-19 July. The lowest DO in this water mass was 0.4 mg/l. Such a cold water mass appeared in early July and it propagated from offshore to the coast. The oxygen consumption rate of the water column was about 0.1 mgO2/L/hour in Hurun Bay. Comparing these oxygen consumption rates and the DO of water, if the oxygen supply was restricted, the water in Hurun Bay could become hypoxic easily.

Abstract

Di waduk-waduk. yang ada di badan air sungai Citarum khususnya waduk Saguling, Cirata dan Juanda; perikanan budidaya dengan keramba jaring apung (KJA) berkembang sangat pesat; sehingga diduga telah melebihi daya dukung badan air waduk dan limbahnya telah mengancam keberlanjutan perikanan budidaya tersebutPada periode 5 tahun terakhir, setiap tahunnya KJA di waduk. Saguling diperkirakan menghasilkan limbah sebesar 29.868.750 kg organik yang mengandung 1.359.028 kg•N dan 214.059 kg•P; di Cirata sebesar 145.334.000 kg organik yang mengandung 6.611.787 kg•N dan 1.041.417 kg •P, dan Saguling sebesar 14.492.250 kg organik yang mengandung 659.397 kg•N dan 103.861kg•PDekomposisi limbah organik tersebut, selain secara langsung menurunkan konsentrasi oksigen terlarut dan menghasilkan gas-gas lain yang dapat membahayakan kehidupan organisme lain, termasuk ikan; juga meng-hasilkan nutrien yang dapat menyebabkan yutrofikasi dan mengakibatkan pertumbuhan fitoplankton secara berlebihan (blooming). Gejala tersebut telah nampak dimana dilaporkan bahwa kepadatan fitoplankton di waduk. Cirata adalah antara 44,80-62,28 x 106 sel•l-1; Saguling antara 19,03-25.39 x 106 sel•l-1 dan Juanda antara 20.04-50.42 x 106 sel•l-1Jika "blooming" ini terus berlanjut karena sumber pencemar tidak mampu dihentikan maka badan air waduk akan didominasi oleh “blue green algae” seperti microcystis sp dan dimasa datang satu demi satu ke tiga waduk. yang ada di DAS Citarum akan berubah menjadi “comberan raksasa” yang di saat ada sinar matahari perairan menjadi hijau pekat berlendir menjijikan, dan disaat mulai gelap disana sini timbul gelembung-gelembung gas.

Abstract

Indonesia is the third largest quantity of rice production country in the world with 64 millions metric tons per year. The quantity of rice that produced is running parallel to the quantity of hay, it can be seen from the harvest per kg to produce 1 to 1,5 kg of rice straw or 64-96 million tons per year. 62% of rice straw burned or used as animal feed, so that when burned, it will cause global warming and also pollution. One effort to provide more value of straw material is to process into products of small medium enterprises (SME), straw treatment alternative chosen was to compacting presses using heat and environmentally friendly adhesives. The method can be a new alternative in the processing of SME products that made by rice straw materials, because rice straw is mostly processed usingwoven. Press method is also a simple method that is commonly found in several SMEs in Indonesia. The output of this research is SMEs product and stationary product was choosen as the sample.Experiments structural adhesive is used internally (binderless) and external (gum rosin and gum damar cat’s eye). Visual experiment divided into the natural character, natural dyes and primarystaining. From the experimental results, we conclude that the best structure is generated from an external adhesive resins cat eye with the quantity of adhesive 20% and visual experiment results isvariation to create a design with a variety of natural visual character of rice straw to modern. Keywords: rice straw, press, environmentally friendly, SMEAbstrakIndonesia merupakan negara dengan kuantitas produksi padi terbesar ketiga di dunia yaitu 64 juta metrik ton. Kuantitas padi yang melimpah tersebut berjalan paralel dengan kuantitas jerami yangdihasilkan, hal ini dapat dilihat dari per 1 kg beras menghasilkan 1 sampai 1,5 kg jerami atau 64-96 juta ton per tahunnya. Mayoritas (62%) jerami dibakar atau dijadikan pakan ternak, apabila dibakarsecara tidak langsung akan menyebabkan pemanasan global serta polusi disekitarnya. Salah satu upaya untuk memberikan nilai lebih material jerami yaitu dengan mengolahnya menjadi produk UKM,alternatif pengolahan jerami yang dipilih adalah dengan metode pemadatan melalui proses kempa panas dan perekat ramah lingkungan. Metode tersebut bisa menjadi variasi baru dalam pengolahan produk UKM jerami, karena saat ini kebanyakan jerami diolah dengan menggunakan teknik anyam. Metode press merupakan metode sederhana yang sudah biasa ditemukan di beberapa UKM diIndonesia. Output dari penelitian ini adalah produk UKM dengan sampel produk perkantoran stationary yang ramah lingkungan. Eksperimen struktur menggunakan perekat internal (binderless)dan eksternal (gondorukem dan getah damar mata kucing), eksperimen visual dibagi atas karakter natural, pewarnaan alam dan primer. Dari hasil eksperimen tersebut dapat disimpulkan bahwastruktur terbaik adalah yang dihasilkan dari perekat eksternal damar mata kucing dengan kuantitas perekat 20 % dan visual adalah variasi desain dengan berbagai karakter visual dari natural hinggamodern.

Abstract

Salah satu isu penting dalam pemanfaatan air tanah di Kabupaten Serang adalah tingginya salinitas di bagian Utara DAS Ciujung dan Cidurian. Masyarakat yang tinggal di area ini umumnya tidak mau menggunakan air sumur dangkal sebagai air minum karena rasanya yang payau. Tingginya salinitas air tanah dangkal berhubungan dengan batuan penyusun dalam bentuk endapan aluvial di bagian utara kedua DAS yang memungkinkan terjadinya intrusi air laut ke daratan. Tujuan dari penelitian ini adalah untuk menjelaskan tentang pola distribusi spasial salinitas air tanah dangkal di bagian hilir DAS Ciujung dan Cidurian berdasarkan kepada hasil pengukuran salinitas secara in-situ. Salinitas air diukur pada 16 sumur dangkal di kedua DAS. Berdasarkan hasil pengukuran, salinitas air tanah dangkal pada wilayah studi dapat dikelompokan pada dua kategori yaitu : air tawar dan payau. Dengan melakukan interpolasi nilai-nilai salinitas menggunakan software ArcGIS extension 3D Analyst, maka diperoleh bahwa telah terjadi intrusi air laut di bagian utara kedua DAS. Berdasarkan hasil analisis, dapat diidentifikasi adanya jebakan air laut di dalam akuifer menggantung di DAS Cidurian dengan nilai salinitas tertinggi ditemukan di Kecamatan Carenang. Salinitas air tanah dangkal di DAS Ciujung dan Cidurian menurun secara eksponesial dari pantai Utara ke arah Selatan. Hasil yang diperoleh diharapkan dapat menjadi bahan pertimbangan dalam pengelolaan air tanah dangkal sebagai air baku air minum di Kabupaten Serang.Kata kunci: salinitas, air tanah, intrusi, jebakan air laut, akuifer menggantung
