<![CDATA[Juwana city is one of a developed potential region that include in a WANARAKUTI (Juwana-Jepara-Kudus Pati) economic unity region. It has 43,282 populations in 2005 with the growth rate  of  populations  was about  1.308%  per  year. The  developing  of  populations  was  followed with the increasing of consumption quantities and other activities which increased production of solid wastes. In 2005, the amount of solid wastes was 133.896 m3/day and the development of bulk sizes of these wastes was 0.4% per year. Ranking of waste management service was 39% and service distribution was 50,47%. One of important aspects that caused low quality of waste management  services  was  the  aspects  operational technology  usage.  It  included  of  waste handling, storage, collection, transfer and transport. The evaluation and development program of waste operational technology was to increase the distribution area and service management of solid wastes up to 90%.]]>

<![CDATA[Fly Ash PT. Pabrik Kertas Tjiwi Kimia, Tbk, memiliki kandungan logam berat Pb sebesar 1,012 ppm dan Cr sebesar 0,811 ppm. Kandungan oksida silika sebesar 71,88%, sehingga berpotensi sebagai material  campuran  pada  pembuatan  bahan  bangunan.  Penelitian  ini  bertujuan  untuk  mengetahui waktu tinggal Pb dan Cr dalam paving block pada variasi volume perendaman yang berbeda. Hasil uji perlindian  dengan  media  perendaman  aquades  menunjukkan  bahwa  semakin  besar  volume  air perendaman semakin kecil konsentrasi logam berat Pb dan Cr.  Sedangkan untuk media perendaman air sumur (studi kasus) menunjukkan bahwa semakin besar volume air perendaman semakin kecil konsentrasi logam berat  Cr dan logam Pb tidak terdeksi. Waktu tinggal logam berat Pb dan Cr pada paving block dengan volume air (aquades) perendaman 7,6 liter pada hari yang ke 22, sedang untuk volume air perendaman 15,2 liter pada hari ke 25. waktu tinggal logam berat Cr pada paving block dengan air sumur (studi kasus) pada perendaman  7,6 liter,  15,2 liter serta 22,8 liter pada hari yang ke 21.]]>

<![CDATA[Pembuangan lindi ini berpotensi mencemari lingkungan dan mengakibatkan gangguan kesehatan. Air lindi TPA Jatibarang dikategorikan sebagai lindi tua karena telah berusia lebih dari 10 tahun dengan nilai COD sebesar 4000 mg/l. Pengolahan lindi menggunakan proses fenton bertujuan untuk mengetahui efisiensi penyisihan kadar BOD, COD, warna di dalam lindi. Â Variasi penelitian meliputi jumlah penambahan H2O2, dan Fe2O3. Reaksi penelitian menggunakan kolom batch yang diaduk menggunakan stirer. Pengolahan air lindi menggunakan fenton menunjukkaan hasil yang cukup baik dalam munurunkan beban limbah organik. Hal ini nampak secara jelas dari penguraian warna berkurang dari 3800 ptco dan 750 ptco. Pada pengolahan fenton Pada dosis Fe/H2O2 sebesar 1,14 gr dan 3,8 ml, penurunan warna yang paling signifikan mencapai 82% sebesar 140 ptco pada waktu proses 2 jam. fluktuasi penyisihan pada penurunan nilai COD. Proses fenton menunjukkan bahwa waktu pengolahan cukup mempengaruhi efisiensi penurunan parameter COD. Pada proses fenton terjadi presentase penurunan hingga 56 % pada 240 menit pada variasi 0,38 gr FeSO4 dan 3,8 ml H2O2. Beban organik yang ditunjukan dengan COD pada lindi awal berkisar 3800 mg/l kemudian di koagulasi flokulasi menjadi 2700 mg/l dan ketika di lakukan proses fenton berakhir pada 1000 mg/l untuk hasil terbaik Fluktuasi penurunan COD pada menit 60 hingga 180. Hasil pengolahan belum dapat memenuhi baku mutu air lindi pada yang terlampir pada Peraturan Daerah Provinsi Jawa Tengah Nomor: 5 Tahun 2012. Namun, penguraian beban organik dan peningkatan rasio BOD/COD pada proses fenton dapat mengoptimalakan pengolahan biologi IPL eksisting berupa kolam oksidasi dapat berjalan dengan baik.]]>

<![CDATA[The exploration and production process of oil and its supporting operations always generates wasteas by-product. If they are uncontrolled, it might decrease the environmental quality. Thus, it isnecessary to manage and treat the waste in order to meet the regulation standard of quality andquantity. PT XYZ is an energy company, particularly oil and gas production, which its productionactivity generate a large amount of waste as well as produced water. Thus, PT XYZ must havefacilities or produced water handling plant which could minimize pollution caused by produced water.PT XYZ already has a system of produced water handling with recycling principle. After oil and waterseparation including water treating at Water Treating Plant (WTP), produced water will be used forsteam injection. This is the part of enhanced oil recovery by steam flooding in Duri Field. Besides,produced water could be used as backwash water at WTP, that is Oil Removal Filter (ORF) and WaterSoftener, which is called brine water. If the produced water and brine water is over load the capacity ofoil enhanced recovery injection, it might be disposed through injection to Disposal Well and there arecertain condition that produced water should be discharged into canal. The objective f this study is toanalyze the performance of a water treating plant in PT XYZ. Water Treating Plant is a facility fortreating produced water. Basically, WTP is on good condition and each unit has high efficiency forseparating oil and water (60-99%). Horizontal velocity at pit #A of API Separator was larger than thedesign criteria. In addition, Water Softeners have efficiency until 99% for the hardness.]]>

<![CDATA[Liner merupakan komponen terpenting dalam fasilitas tempat pengolahan akhir (TPA) sampah untuk mencegah lindi mencemari tanah. Bahan yang sering digunakan sebagai liner adalah tanah lempung yang memiliki permeabilitas rendah. Salah satu tanah lempung alami yang dapat digunakan sebagai liner TPA adalah bentonit. Bentonit memiliki permeabilitas yang sangat rendah, namun stabilitas gesernya tidak begitu kuat sehingga berpotensi mengalami keruntuhan apabila digunakan di daerah lereng.Di sisi lain, limbah bangunan yang berupa pecahan batu bata, campuran pasir dan semen, serta beton memiliki kuat geser yang tinggi dan berpotensi sebagai campuran bentonit. Pada penelitian ini, limbah bangunan sebanyak 5%, 10%, dan 15% ditambahkan pada bentonit untuk meningkatkan kekuatan geser bentonit sehingga didapatkan campuran bahan semi kedap dengan stabilitas yang lebih tinggi dan permeabilitas rendah. Hasil uji stabilitas geser yang dilakukan pada tegangan normal 50 kPa , 100 kPa, dan 200 kPa menunjukkan bahwa semakin meningkatnya konsentrasi campuran bahan bangunan, maka semakin meningkat pula nilai tegangan geser yang dihasilkan]]>

<![CDATA[Flood  mitigation  is  a  part  of  water  resources  management  widely  with  scope  are  consist of conservation, controlled and water used. The concept of water controlled is called Flood Control or Flood Mitigation/Flood Damage Mitigation. There are two kinds of flood control, structural and non structural effort. Structural effort is an effort which tends to engineering technique which is aimed to modification the flood discharge and the stage of flood damage. Flood discharge (Q, m3/sec) is the function of velocity (V, m/sec) and cross section area of the river/channel (A, m2). Efforts  of  flood  control  can be  carried  out by  justified  of  the  third  components.  Non-structural  effort  is  aimed  to  avoid  and  press  the problem  that  caused by  flood  with  some  activities  like arrangement  of  flood  plain  and  watershed development.   Non-structural   effort  usually  is conducted  for  long  period  goal.  Therefore  carrying this  effort  need  consistency  all  of stakeholder.  Participatory  approach  from  stakeholder  is  the  key of  success  of  non  structural effort.]]>

<![CDATA[During this time, the remaining milk that has been consumed only wasted. Milk content is strongly associated with nutrients to increase crop productivity. This requires innovations in the manufacture of organic fertilizer products. The purpose of this study was to determine the best composition comparison between stale milk, EM4 solution and cocopeat in the process of making liquid and solid organic fertilizer and determine the c-organic value, Ntotal, P2O5total, K2Ototal, and pH value. Initial analysis of liquid organic fertilizer obtained pH values of 5.10, P2O5total  of 0.342% and Ntotal of 0.569% at initial control (stale milk only) and final values of 1.010% of P2O5total, 1.113% of Ntotal and 10.480% of organic carbon in R3 ( 30: 5: 1). Initial analysis of solid organic fertilizer obtained pH values 5.26%, 2.668% P2O5total, 0.952% K2Ototal and 2.780% Ntotal at R1 (10: 5: 1) and final values obtained 1.578% P2O5total at R1 (10: 5: 1) , 2.937% Ntotal in R2 and 43.912% carbon organic in R3. This shows that stale milk with the addition of EM4 and cocopeat solutions has an effect on phosphorus and nitrogen nutrients in liquid and solid organic fertilizer.]]>
