Abstract

The port of Tanjung Emas Semarang was located at the coast needed more clean water for shipping,industries and the communities. The production process of PLTU Indonesia Power produced waste wateras cooling water that caused thermal pollution. Considering the quality, quantity, and continuity of thatwaste water used as one of alternative source of clean water. It treated using by multistageflash recycleddistillation method. The purpose of this plant to fulfill clean water for shipping and port of Tanjung Emasarea with production capacity was 50 liters per seconds for duration planning about 15 years. The locationof this plant was next to PT. SRIBOGA with area 8000 m2, wherein the intake on the Canal of PLTUIndonesia Power. In order to fulfill the quality of water, this plant used oil separator and antiscalant aspretreatment. Production cost of distillation plant was Rp 13.647 per m3. This cost was too expensive so itrequired to be done crossed subsidy. The price of clean water was Rp 2000 /m3 for public, Rp 5500 per m3for industries and Rp 3000 per m3 for governmental office.

Abstract

Di Indonesia, air limbah domestik merupakan pencemar terbesar yang masuk ke badan air.Pemantauan dan pengendalian air buangan dapat dilakukan salah satunya denganmeningkatkan pelayanan dalam hal sanitasi. Pemerintah menetapkan target terhadap tahun2015-2019 antara lain 100% capaian pelayanan akses air minum, 0% proporsi rumah tanggayang menempati hunian dan permukiman tidak layak (kumuh) di kawasan perkotaan dan 100%capaian pelayanan akses sanitasi. Perencanaan masterplan ini bertujuan untuk menyediakanfasilitas sanitasi yang memadai dalam pengelolaan air limbah domestik terutama di wilayahperkotaan Kabupaten Sukoharjo. Masterplan ini akan mengkaji aspek teknis-teknologis dalamperencanaan pengelolaan air limbah domestik. Pada masterplan ini direncanakan akandibangun 3 buah IPAL skala perkotaan dan 8 buah IPAL skala permukiman besar yang akanmelayani 20% penduduk perkotaan Kabupaten Sukoharjo. IPAL skala perkotaan direncanakanterdapat 2 buah di Kecamatan Grogol dan 1 buah di Kecamatan Kartasura. IPAL skalapermukiman besar direncanakan terletak di Kecamatan Kartasura, Kecamatan Gatak, 2 buah diKecamatan Baki, masing-masing 1 buah di Kecamatan Bendosari, Gatak, Polokarto danKecamatan Sukoharjo. Selain itu, untuk pelayanan sistem setempat direncanakan 3 (tiga)daerah pelayanan IPLT yang dibangun secara bertahap. Tahap pertama yaitu optimalisasi IPLTEksisting (IPLT Mojorejo), tahap kedua yaitu pembangunan IPLT di Desa Bekonang KecamatanMojolaban, dan tahap ketiga pembangunan IPLT di Desa Grajegan Kecamatan Tawangsari.IPLT direncanakan dapat melayani sekitar  70% penduduk perkotaan.

Abstract

Jumlah sampah di Indonesia semakin meningkat, seiring dengan peningkatan jumlah penduduk. Namun, pengolahan sampah di Indonesia masih berupa penimbunan sampah di TPA yang menimbulkan dampak negatif bagi lingkungan. Oleh karena itu diperlukan suatu pengolahan sampah alternatif yang dapat meminimalisir pencemaran salah satunya adalah pencemaran udara. Biodrying merupakan salah satu metode yang menawarkan solusi berkelanjutan untuk pengolahan sampah perkotaan. Namun, proses biodrying masih menghasilkan gas rumah kaca. Tujuan penelitian ini adalah untuk mengetahui  bagaimana pengaruh penambahan debit udara dan variasi debit udara terhadap parameter emisi gas rumah kaca, terutama CO2 pada pengolahan Municipal Solid Waste (MSW) dengan metode biodrying dan mengetahui berapa besar debit udara yang optimum untuk menghasilkan emisi gas CO2 yang paling minimum pada pengolahan Municipal Solid Waste (MSW)  dengan metode biodrying. Variasi debit udara pada penelitian ini adalah 0 l/m, 2 l/m, 3 l/m, 4 l/m, 5 l/m dan 6 l/m. Pengambilan sampel emisi dilakukan pada hari ke-1,ke-2, ke-15 dan ke-30. Hasil dari penelitian ini adalah proses biodrying menghasilkan emisi dengan rata-rata CO2 sebesar 6214,66 ppm. Penambahan debit udara pada proses biodrying mampu menurunkan emisi CO2 sebesar 74,5%. Debit optimum yang diperoleh dari penelitian ini adalah sebesar 6 liter/menit

Abstract

Biogas was a gas produced from biological activities in anaerobic fermentation processes and as  a renewable  energy.  This  research  was  to  find  out  the  effect  between  elephant  manure, elephant urine, water and starter to reduce biogas production and calorie value. This research is divided  into  three groups  based  on  the  raw  material,  i.e.,  elephant  manure,  elephant  urine, water  and  starter  as independent  variabels.  Observation  is  consisted  of  biogas  production volume and calorie value. This result showed that in 21 days, elephant manure mixtured with elephant urine with ratios of 1:2  was the best material to produce biogas, that was 60,800 ml of biogas and 5345.39 cal/liters of calorie value.

Abstract

Water  was  the  fundamental  needs  for  industrial  in  every  production  process  and  all  the activities. Apac  Inti  Corpora  company  was  the  textile  industrial  with  production  process  are spinning  and weaving.  It  usually  required  water  with  high  quality  such  as  lowest  pH  and hardness. They needed high quality water by water treatment plant. They treated ground water that contained manganese and iron to fulfill domestic needs by aerasi and filtrasi with filter sand. They  treated  water  from  Bade  river  and Sarana  Tirta  Ungaran  to  fulfill  non  domestic  needs. Water  from  Bade  river  contained  highest colour  and  turbidity  and  processed  with  screening, coagulation, flokulalation, sedimentation and filtration. To eliminate content of hardness, these water continued to treat by  softener unit. Softener  unit will degrade kesadahan less than 5 ppm CaCO 3 . Quality of treated water has been fulfilled Permenkes RI No.907/MENKES/SK/VII/2002, except colour content from Bade river.

Abstract

Small laundry was one of home industries that grown rapidly. Small laundry industries usually disposed their  wastewater  straightly  to  the  city  drain  system  without  any  treatment  before.  It caused a large amount of phosphate accumulating in the sewage. Because of the environment was  unable  to handle  it  by  themselves,  we  needed  a  simple,  cheap,  and  applicative  way  to reduce phosphate. Phytoremediation was one of methods to remove phosphate. This research used  water  hyacinth. Phytoremediation  was  be  done  by  planting  water  hyacinth  in  the phosphate  wastewater.  By  doing this  we  expected  that  water  hyacinth  would  absorb  the phosphate  from  the  water.  The experiments  was  taken  for  5  days  with  phosphate concentrations of 200 mg/liters; 250 mg/liters; 300mg/liters. At early concentrations of 200mg/l showed that water hyacinth could reduce phosphate until 24.03% or about 144,1603 mg, for the early  concentrations  of  250  mg/l  showed  that  water  hyacinth could  reduce  22.95%  or  about 172.1209 mg and for the early concentrations of 300 mg/liters showed that water hyacinth could absorb about 20,87 % or around 187.860 mg. From the statistic test showed that life time in the wastewater gave a significant result to the ability in absorbing phosphate by the water hyacinth.

Abstract

Abstract Offset industries produced waste water contained lead contaminant and had pollution potential for environment. One of method to remove waste water contained lead was used bottom ash as adsorbent. This research was to know the ability of  bottom ash to reduce lead in artificial waste water with concentration of lead was 20.64 mg/l in the batch and continuous processes. For the batch processes, bottom ash was used as independent variable of 0, 1, 3, 5, and 7 weight gram and highest removal efficiency up to 72.09-90.84%. While in continuous process experimental used column with diameter of 2 inch, discharge of 760 ml/minute, and influent concentration of 15 mg/l, 20mg/1, and 25 mg/l. Highest efficiency of removing lead was 73%-92.93%. With velocity constanst was 0.416-0.490 ml/mg. Second while operational capacity was 0.069-0.081 mg/g. Keywords:offset, adsorption, waste water, lead, coal bottom ash
