Organic material from municipal solid wastes can be recycled by compostingtechnology become organic fertilizer. One kind of composting technologies isvermicomposting that use earthworm as ‘machine” of composting process. Thereare two products from the process: biomass of worm and casting. Vermicomposting consists of three phases of activities such as preparation,processing, and nursing phase. Preparation phase consists of choosing oflocation, system, building, and equipment. Processing phase consists of making of worm media, preparation of worm and planting. Nursing phase consists of feeding, turning, cropping of casting and controlling of the disease. This article talk about those phases and the classification and characterization of earthworm.

Cassava peels is one of agriculture waste having potency as feed for poultry. CassavaÃ‚Â peels represent waste product from cassava industry with amount 1,998 million ton inÃ‚Â the year 2006 in Indonesia (10 percentage of corm of yielded cassava). The weaknessÃ‚Â of cassava peels are low crude protein content, less palatable for ruminant and haveÃ‚Â voluminous characteristic. One of the effort to increase usefulness of cassava peels isÃ‚Â by using cassava peels as fibre source in pellet complete ration for poultry. The aim ofÃ‚Â this research was to know best level from utilization of cassava peels as physic qualityÃ‚Â in poultry complete ration. This study used Completely Randomized Design that consistsof three treatments and three replications. The treatments were: 1). Control feeds + 0%Ã‚Â cassava peels (R1), 2). Control feeds + 30% dry matter cassava peels (R2), 3). ControlÃ‚Â feeds + 30% boiling matter cassava peels (R3). Data was analysed with ANOVA andÃ‚Â continued with Duncan Test. The result indicated that effect of water content pelletÃ‚Â ration with moisture tool is higher than using infrared tool. Pellet rations with dry matterÃ‚Â and boiling matter control treatment before saving have physic qualities that still meetÃ‚Â the quality standar of poultry ration. Eventhough, on treatment after saving, the physicÃ‚Â qualities decrease and relatively less meet the quality standar of poultry rationKey word: waste, cassava peels, poultry ration, pellet complete.

ABSTRACTWater pollution is a problem that often arises and gives a serious impact to the environment. Therefore, it should be reduced by conventional methods or modern methods. The submerged biofilter is a biological waste treatment plant that utilizing microorganisms grown in a packing medium. The advantages of submerged biofilter as a waste treatment plant are easy to use and low energy consumption so the operational cost is cheaper. This study aims to determine the operational parameters of the submerged biofilter and to develop a model that can be used to estimate the rate of elimination of each pollutant using nitrification reactor for ammonia and denitrification reactor for phosphate. The experiments were conducted with draining the wastewater in a cylindrical bio-filter column in which the hight is 90 cm. At first, the microorganism was grown for two weeks with the residence time of one day. Furthermore, the wastewater removals are conducted with hydraulic loading rate (HLR) variation of 0.44; 0.55; 0.74; 1.11; 1.66; 2.21; and 3.32 m3/m2/day. Then the effluent from the outlet is analyzed using UV-Vis Spectrophotometer. The results showed that the optimum ammonia and phosphate removal was obtained in 0.44 m3/m2/day for ammonia removal and 1.66 m3/m2/day for phosphate removal. While the removal of ammonia and phosphate percentage from both conditions are 97.41% and 27.16% respectively. The changes of HLR will give an effect on substrate reduction rate (SRR), and the percentage of substrate removal. The model developed based on efficiency factors presented a good approach to represent the concentration of substrate effluent at various HLR. Keywords: wasteswater, nitrification, denitrification, submerged biofilter ABSTRAKPencemaran air merupakan permasalahan yang sering muncul dan berpengaruh serius pada lingkungan. Oleh karena itu, perlu dilakukan usaha yang berkelanjutan untuk dapat mengurangi dampak dari pencemaran tersebut, baik dengan cara-cara konvensional maupun inovasi teknologi terbaru. Biofilter tercelup (submergedÃ‚Â biofilter)Ã‚Â adalah suatu alat pengolah limbah secara biologi dengan memanfaatkan mikroorganisme yang ditumbuhkan dalam media packing di dalamnya. Kelebihan penggunaan biofilterÃ‚Â tercelupÃ‚Â sebagai alat pengolah air limbah adalah pengelolaannya yang mudah dan konsumsi energi yang rendah sehingga biaya operasionalnya murah. Penelitian ini bertujuan untuk mengetahui parameter operasional biofilter tercelup dan mengembangkan model untuk memperkirakanÃ‚Â laju penyisihan setiap polutan menggunakan reaktor nitrifikasi untuk limbah amonia dan reaktor denitrifikasi untuk fosfat. Percobaan dilakukan dengan mengalirkan limbah pada sebuah kolom biofilter berbentuk silinderÃ‚Â dengan ketinggian 90 cm. Pada mulanya mikroorganisme ditumbuhkan dengan mengalirkan limbah selama dua minggu dengan waktu tinggal cairan satu hari. Selanjutnya dilakukan penyisihan limbah dengan variasi kecepatan beban hidrolik (HLR)Ã‚Â sebesar 0,44; 0,55; 0,74; 1,11; 1,66; 2,21; dan 3,32Ã‚Â m3/m2/hari. EffluentÃ‚Â dari keluaran reaktorÃ‚Â kemudian dianalisis menggunakan Spektrofotometer UV-Vis. Hasil penelitian menunjukkan bahwa kondisi optimumÃ‚Â penyisihan amonia dan fosfatÃ‚Â adalah 0,44 m3/m2/hari untuk penyisihan amonia dan 1,66Ã‚Â m3/m2/hari untuk penyisihan fosfat. Persentase removalÃ‚Â amonia dan fosfatÃ‚Â dari kedua kondisi tersebut berturut-turut sebesar 97,41% dan 27,16%. Perubahan HLR berpengaruh terhadap kecepatan penyisihan limbah (SRR), dan persentase limbahÃ‚Â tersisihkan. Model yang dikembangkan berdasarkan faktor efisiensi memberikan hasil yang cukup baik untuk merepresentasikan besarnya konsentrasi effluentÃ‚Â limbahÃ‚Â pada berbagai variasi HLRKata kunci: limbah cair, nitrikasi, denitrifikasi, biofilterÃ‚Â tercelupÃ‚Â

Pada abad 18 telah dimulai revolusi industri antara lain dengan dibuatnya pabrik-pabrik, pembangkit listrik, kendaraan transportasi dan pertanian. Dua ratus tahun kemudian, negara-negara industri baru bermunculan baik di Eropa, Amerika bahkan di Asia. Industri memang membuat wajah dunia tampak semakin maju, misalnya kendaraan bermotor sebagai salah satu produk industri. Namun di sisi lain berdampak negatif terhadap lingkungan hidup manusia. Mesin-mesin kendaraan itu menggunakan bahan bakar dari bumi. Hasil pembakaran bahan bakar tersebut menghasilkan unsur CO dan CO2 yang menumpuk di udara dan akan menghasilkan efek seperti rumah kaca terhadap cahaya matahari yang akan masuk ke bumi. Bumi seolah-olah dilapisi oleh kedua gas tadi. Akibatnya, bumi terasa lebih panas dari biasanya. Hal ini disebut sebagai pemanasan global (Global Warming)

The green revolution in the 19th century, has met expectations in an effort to increase the productivity of food supply, in the world at least in Indonesia. In the course of time the green revolution movement has given the systemic impact not only on the degradation of ecosystems, but also the productivity of land, especially paddy fields due to the use of agrochemicals that have been over threshold. The impact on soil in Indonesia become ill, there is a change of soil structure, become poorer and finally lost as the land carrying capacity of production. Systemic Degradation covering 18 000 ha of wetland, contamination levels of heavy metals such as Hg, Fe, Cd, Cu has been on conditions that endanger human health also pesticide has an impact resistance to pests.Recovery efforts of agricultural land, will take time, and cost is not cheap. Various studies have been done, to remediation land by using acid-humic substances, and gives results quite encouraging, because itÃ¢â‚¬â„¢s quite effective, efficient and inexpensive, compared with conventional methods is to provide an organic material such as kompost.

The pattern of the land, natural resources and environment used will influence the sustainability of a city. Nowadays, many cities in Indonesia have been developed without consideration of ecological aspects. The development of built areas that tends to be sprawling and convert natural environments such as forests and other green areas, wetlands, and lakes that have ecological functions has been causing the increasing environmental problems such as floods, groundwater shortage, and micro climate change in many cities. Spatial planning that considers thesustainability of ecological functions is a strategic tool to manage the city’s land allocation so as to achieve sustainable cities. However, most spatial planning products of cities have been made without the support of ecological data and analysis in the planning process. The paper discusses the importance of maintaining the ecological spaces as a part of an urban ecosystem and decribes the concept of sustainable spatial planning, including data and analysis should be prepared in order to integrate ecological consideration in the sustainable spatial planning process.

Neraca air spasial DAS Cerucuk, pulau Belitung telah dikembangkan untuk mengevaluasi ketersediaan sumberdaya air dalamrangka pengelolaan sumberdaya air yang berkelanjutan. Pendugaan neraca airspasial bulanan dilakukan dengan metoda SCS, distribusi tegangan pori dan perbedaan konduktivitas hidraulik berdasarkanpenggunaan Sistem Informasi Geografis (SIG). Data dasar yang digunakanyaitudata curah hujan harian dari 5 (lima) stasiun pencatat hujan yang berasal dari milik BMKG (2 stasiun) dan milik perkebunan kelapa sawit (3 stasiun), data citra satelit Landsat 8 tahun 2013, peta tanah dan peta geologi pulau Belitung. Hasil perhitungan menunjukkan bahwa air permukaan dan airtanah dangkal cukup tersedia untuk keseluruhan DAS Cerucuk. Airtanah dangkal tersedia pada setiap bulan sepanjang tahun,bahkan pada bulan Agustus ketersediaan air masih cukup banyak. Pengisian airtanah dalam relatif sedikit karena sebagian besar DAS Cerucuk tersusun oleh formasi granit Tanjung pandan yang hampir tidak memiliki kelulusan. Akifer airtanah dalam tidak ditemukan. Total curahhujan yang jatuh di DAS Cerucuk akan lepasmelalui evapotranspirasi (36%), menjadi air larian (34%), mengisi airtanah dangkal (28%) dan mengisi airtanah dalam (1,7%). Hasil penerapan model terhadapsetiap jenis tutupan lahan memperlihatkan bahwa air hujan yang jatuh pada jenis tutupan lahan hutan, perkebunan dan pertanian lahan kering menghasilkan jumlah imbuhan airtanah dangkal cukup besar, sedangkan untuk lahan basah, pemukiman dan kolong area tambang sebagian besar mengalir sebagai air larian.Hal ini menyebabkandi daerah pemukiman pada musim kemarau dirasakan adanya periodedefisit air.Pengendalian daerah pemukiman dan pelestarian daerah bervegetasi di selatan DAS Cerucuk sangat diperlukan untuk menjamin kelestarian sumberdaya air.Kata kunci: neraca air, spasial, metode SCS, ketersediaan sumberdaya air.

Dalam rangka memperbaiki kualitas perairan Sungai, vetiver (Chrysopogon zizanioides) telah ditanampada kawasan bantaran Sungai CIkapundung selama 63 hari. Dua wadah dialiri dengan sumber air yangberbeda, yaitu air sungai dan air tanah (sumur). Produksi biomassa diukur setiap 20 harian sekali,dengan fokus pengukuran pada pertumbuhan tunas dan akar vetiver. Secara umum, pertumbuhan tunasdan akar vetiver yang ditanam pada wadah yang dialiri air sungai tumbuh lebih baik (panjang) daripadavetiver yang ditanam pada wadah yang dialiri air tanah. Data pengukuran berat kering biomassamenunjukkan bahwa hingga waktu ketiga pengambilan contoh, perpanjangan akar lebih cepat daripadaperpanjangan tunas. Data-data tersebut menunjukkan bahwa vetiver memiliki kemampuan yang sangatbaik dalam memanfaatkan nutrien yang berasal dari limbah organik Sungai Cikapundung. Oleh karenaitu, vetiver dapat diusulkan sebagai tanaman untuk aktivitas fitoremediasi di kawasan bantaran SungaiCikapundung. Pertambahan panjang akar vetiver yang lebih cepat daripada pertambahan panjangtunasnya juga dapat dimanfaatkan sebagai tanaman anti longsor di sepanjang kawasan bantaran sungai.
