Abstract

Tempat Pembuangan Akhir Sampah (TPA) Supit Urang Malang memiliki Jumlah sampah yang potensial menghasilkan gas Metana. Teknologi tepat guna ekstraksi gas metana dan pemasangannya diperlukan mengingat tidak tersedianya peralatan yang memadai kecuali backhoe ekscavator. Peralatan flaring dengan sistem monitoringnya diperlukan untuk memperoleh karakteristik produksi gas metana. Disain peralatan dan pemasangan pipa ekstraksi menggunakan metode Pahl & Beitz. Backhoe excavator yang dipergunakan dalam percobaan ini, ternyata kurang kuat untuk menekan pipa pendorong, Disarankan untuk pemasangan pipa ekstraksi sebaiknya menggunakan pile hammer, yang dipakai untuk pemasangan tiang pancang pada tegangan tanah 700 kg/cm2 karena tegangan yang pada timbunan sampah 200 kg/cm2. Produksi gas metan sedikit pada malam sampai pagi, produksi membaik mulai pukul 7 pagi dan puncaknya sekitar pukul 2 siang dengan konsentrasi mencapai 47 hingga 55 kemudian produksi metana berkurang, dan turun drastis mulai pukul 5 sore.

Abstract

o simplify the planning process needs reinforcement in reinforced concrete structures in simplehouses, which meet the requirements of security and comfort, requires the calculation process byusing a formula that is long enough that perhaps could only be understood by an engineer in thefield of Civil Engineering. In this subprogram II will be built a Dimension Beam OptimizationProgram Child and Parent Beams in Neutron Numerical approach Moment Style, Style and StyleNormal latitude necessary to determine the need for reinforcement beams. By simply entering someform of data input length of the beam on the program this application will get installed on thereinforcement requirements for reinforced concrete structures along with their material needs onthe job for the House Story Concrete Simple. Thus it is possible people will be able to calculateawampun needs reinforcement and concrete materials that are required on the job simple storyhouse.

Abstract

Village Donowarih Karangploso District of Malang Regency is one of the areas that havetrouble and waste management in the central (dumped in landfills / TPA) where the existing landfillis very far from the village Donowarih with a distance of approximately more dari15 miles by roadup kontour conditions down so it can be concluded is not likely to be transported to a landfill. Sothat the Village Donowarih require a landfill area (TPA) that is close and be able to serve the communityin the surrounding area.With topography at the foot of the mountain Arjuno the Landfill to be built so the potential topollute the environment, especially water and soil in areas that have a height below the surfaceDonowarih village, so it becomes very important that a comprehensive landfill design which focuseson health aspects of the environment.With reference to kaedah comprehensive planning Landfill is expected to have DonowarihVillage Landfill that meet environmental health standards are accompanied by a simple application ofwaste regulations for the village community Donowarih so it will get additional revenue through therecycling process that accumulates.

Desain Interkoneksi Bioreaktor Sampah Padat Perkotaan Dengan Model Sirkulasi Air Lindi Anaerob Untuk Meningkatkan Produksi Gas MethaneZamzami SeptiropaStaf Pengajar Jurusan Teknik Sipil , Fakultas TeknikUniversitas Muhammadiyah Malang,e-mail :  zamseptiropa@umm.ac.idABSTRACTThe existence of gravity of the pressing weight of its own garbage heap of garbage will be squeezed to make trash (pressing) and out of the leachate (Leachate). Contained in the waste leachate has elements glokosa (C6H12O6), Amino Acid and Ammonia (NH3), which will help the growth of anaerobic  bacteria  that  produce  methane  (CH4)  and  carbon  diaoksida  (CO2).  Humidity  will  be reduced as the discharge of garbage in garbage leachate resulting decline in productivity of anaerobic bacteria, thus maintaining levels of humidity (moisture content) is very important in stabilizing the productivity of anaerobic bacteria.In  the  humidity  of  59.85%  productivity  waste  anaerobic  bacteria  produce  landfill  gas  in stagnant in the  range  of  less  than  10%  CH4.  With  a  circulation  process  of  garbage  leachate  to maintain moisture of 67.25% are able to stabilize the production  of landfill  gases, especially CH4 concentration more than 25%. Leachate circulation periodically able to stabilize the moisture content of waste, from which the waste water content, it makes the productivity of stable anaerobic bacteria produce methane gas in concentrations between 20% -25% is quite a power plant of energy.Renewable energy was from waste to be more realistic to be implemented in full scale in place of final processing (TPA) / Landfill.  So the need for energy for the benefit of the power plant could help meet the electricity needs of the community.Keywords: bioreactor anaerobic, leachate circulation

Abstract

Drilling system on a pile of waste to get the methane gas is very difficult because the majority of waste that is made from plastic so it can get caught in the drill. Manual excavationis not allowed because it is very dangerous, while digging with heavy equipment has not been able to do because it requires a special tool that is able to push and pull waste surface. Makingholes with arrow system method that is larger arrowhead from the arrow shaft, is one alternative that can be tried to get a hole / gas extraction wells at the Landfill Supit Urang - Malang.Results hole larger than the arrow shaft is then filled with gravels as well extration methane in the landfill. The force required pile (arrow system) to the pole with pole diameter 26.7 cm and a maximum depth of 5.20 m (at point 1, the arrows point of 30Ëš and 45Ëš) is a row of 63,087 kg and 79,717 kg . Optimum angle in terms of penetration force needs is the pole with arrowhead angle 30Ëš.
