Lindi merupakan salah satu penyebab pencemaran air di sekitar TPA. Lindi adalah cairan yang telah melewati sampah dan mengekstraksi material terlarut dan tersuspensi yang sangat halus dari sampah yang ditimbun di TPA, mengandung sejumlah zat-zat kimia beracun, bakteri patogen, senyawa organik dan konstituen lainnya yang terlarut dan tersuspensi di dalam tanah. Hal ini menyebabkan kandungan logam dan material organik dalam lindi sangat tinggi, seperti Fe 19,205 mg/l dan nitrit 1,48 mg/l. Pada penelitian ini akan dilihat penurunan konsentrasi Fe, nitrat dan konsentrasi nitrit pada lindi TPA Piyungan dengan proses elektrokoagulasi – sedimentasi dan filtrasi menggunakan elektroda tembaga dan aluminium. Dengan variasi dosis tawas (1500 ppm dan 2000 ppm) dan waktu kontak (25 menit, 50 menit, 75 menit dan 100 menit). Hasil dari penelitian ini didapatkan efisiensi penurunan terbaik 84 % untuk parameter Fe, 77 % untuk parameter nitrat dan 97 % untuk parameter nitrit pada bak filtrasi dengan koagulan tawas 1500 ppm dan waktu kontak 25 menit. Efluen hasil elektrokoagulasi bila didasarkan pada baku mutu kualitas air golongan empat PP. No. 82 Tahun 2001 nilai konsentrasi Fe, nitrat dan nitrit sudah memenuhi baku mutu dipersyaratkan yaitu konsentrasi Fe sebesar ≤ 5 mg/l, nitrat sebesar 20 mg/l dan nitrit sebesar 0.06 mg/l.Kata kunci: Elektrokoagulasi, Filtrasi, Lindi, Sedimentasi

Palm Oil Mill Effluent treatment produces sludge as byproduct. The sludge produced will cause problems for environment if there are no actions and treatments taken toward the sludge. The purpose of this research is to reduce the pollution of palm oilmill effluent with aerob composting methods using sludge, boiler ash and palm oil fiber. The instrument used is a simple composter with 60 cm height and 30 cm diameter. The sludge is mixed with boiler ash, fiber and organic waste, and then EM-4 was added as an activator. This research used the addition of 0,7 % EM-4activator, with variations of stack’s height are 40, 45 and 50 cm to find out the optimal height to achieve thermophylic condition and the quality of the compost produced. The result of this research shows that compost with 50 cm stack’s height reached the highest temperature of 47,30C. The quality of the compost produced meets the SNI’s 19-7030-2004 requirement. The compost is mature at the 21st day with result Rasio C/N= 12,2. The conversion of palm’s oil sludge into compost can beused as an alternative in utilization waste into valuable product.Keywords: boiler ash, compost, EM-4 activator, fiber, palm’s sludge

The increase in vehicle ownership causes transportation activities to increaase. The tendency to increase the number of motorized vehicles operating, will add to the burden of traffic one example is the increase in noise intensity. This study aims to map the pattern of noise distribution and to determine the level of noise that occurs in Jenderal Sudirman street Pekanbaru city by taking data in the form of noise data and several other traffic variables such as vehicle volume and speed. This research was conducted using a Sound Level Meter (SLM) and with a noise mapping method for 2 days, namely on Monday which represents peak hours and Saturdays which represent vehicle quiet hours. The results showed that from 180 measurement points the highest noise level was 97.9 dB which was a point with high traffic volume and the lowest noise level was 68.4 dB which had low traffic volume. Comparison of noise level with KepmenLH No.48 / MENLH / 11/1996 quality standard results obtained 4 points in the Sukaramai Market. Noise mapping using the ArcGis 10.3 software program.From this study it can also be concluded that the greater the volume of the vehicle, the vehicle speed will be lower so as to produce a high noise level, and vice versa so that the volume of the vehicle is directly proportional to the noise level, while the vehicle speed is inversely proportional to the noise levelKeywords: Noise, Traffic, Jenderal Sudirman Street

The process of palm oil mill wastewater treatment produced by-product as sludge. Sludge generated made a problem for environment and for industry when no handling and processing of the sludge. The purpose of this research is to reduce the pollution of palm oil mill wastewater by composting method with sludge, boiler ash and fiber (fiber) material of palm oil. Sludge mixed with boiler ash, fiber, and domestic wastethen added activator EM-4. Thisstudy used variety of activators EM-4 for 0,5%, 0,7%, 0,9% and control as comparator to optimize the composting process. The result showed that the compost with activator EM-4 for 0,7% likely matured faster because C/N ratio was suitable of SNI 19-7030-2004 and did not shows significant differences. Compost matured in the 21th day with result (C-org 27.22; Ratio of C/N = 10.76;). Based on these results, palm oil sludge can be used as compost by using activators EM-4.

The increasing amount of plastic waste raises its own problem for the enviroment. The prolem is caused by the difficulty of biologically decomposing of the plastic waste. Various efforts have been made to reduce plastic waste. One way to use plastic waste is to process it into liquid fuel through the pyrolysis process. The study aims to determine the effect of each temperature variation and percent of catalyst from the activated carbon on the yield produced by the polypropylene type plastic, and characterization of the resulting liquid fuel. The pyrolysis was carried out at a temperature variation of 3000C, 3500C, 4000C, and the percent of the catalyst variaton from the activated from 5%, 6%, 7%, and without the catalyst, with a reation time of 120 minutes. The results of this study produced the highest yield of 70,03% at 4000C by adding catalyst from activated carbon by 7%. The characterization of the fuel produced was 0,870 gram/ml in density, kinemati viscosity at 2,868 eSt, flash point at 520C, and calor value at 44,696 Mj/kg.Keyword: liquid fuel, heating value, pyrolysis, polypropylene, active carbon.

The production process at PT. Lembah Karet which processes raw rubber into crumb rubber is divided into wet and dry production stages. Which in the production process produces noise from the use of machines. Noise arising from the use of machines unwittingly will cause disruption of bodily functions in workers, especially in hearing loss. The purpose of this research is to know the intensity of noise resulting from the use of machines, noise mapping, evaluation of noise intensity, exposure time and noise control efforts. In this research measurements of temperature, wind speed and noise intensity using a Sound Level Meter (SLM). The results of this research found that the highest temperature reached 35,5oC and the lowest temperature reached 29 oCKeywords: Temperature, PT. Lembah Karet, Noise
