Abstract

Along with the increasing number of urban population and urbanization, it will grow a lot of waste generated as well. According to the Department of Hygiene and the city, the rate of domestic waste generation in the Purbalingga is 2,734 L / person / day, so that waste generation in the Purbalingga each day is 132,40 m3/day. But the ministry is still 84%. To reduce the amount of waste generated in the Purbalingga district has made ​​the electoral garbage in their respective homes. Given the role of such a society, the waste produced by the settlement will be slightly reduced, where the waste could still be recycled back can still be useful. Based on the need to evaluate the condition of the existing waste management and to the development of waste management systems in the Purbalingga.

Abstract

With the increasing amount of human needs for energy, a new energy source is needed to replace the use of fossil fuel which existence becoming rare. One alternative energy than can be used is biogas. Biogas is a gas formed from organic matter decomposition in an anaerob condition. Biogas can be made from materials easily found in the environment, such as restaurant waste that has high organic components. To improve biogas production, there are several treatments that can be done, such as dilution and mixing. This study uses 10 digesters, each of it filled with 4 kg restaurant waste and 1.5 L cow rumen, with the addition of water varies as follows: 6000 ml, 4000 ml, 2600 ml, 1500 ml and 670 ml. The first five digesters were being mixed while the other five were not. The observation runs for 22 days.  Result shown that in both digesters with water content as much as 6000 ml, with mixing or not, are the ones that produce the most gas. First digester produces 1032.02 ml gas while sixth digester produces 1196.99 ml gas. To compare the effect of mixing, gas production on digesters with no mixing produce more gas than the one that are being mixed.

Abstract

Presence of garbage is still likely to be perceived as something useless and harmfull. Problems that often arise in the handling of municipal solid waste is the growing number of population and PDRB causing amount of waste generated will also increase. Waste management conditions in district Bringin, Pabelan, Tengaran, and Suruh is still not optimum when viewed from the operational techniques aspect. This can be seen from the new service area reaches 9%, 10%, 10%, and 7% from total amount of the whole district. Under these conditions need to be planning for waste management systems to unserved areas that could potentially result in high waste generation. With this planning area is expected garbage management services in district Bringin, Pabelan, Tengaran, and Suruh can be increased.

Abstract

 Ngronggo landfill which classified as young landfills is young are less than 10 years old so it still has a high organic content. So it needs some treatment system to treat leachate which generated by the waste degradation process so it does not pollute the environment. In this study the parameters that will be examined are the Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS). Biofilter treatment used is a combination of aerobic to anaerobic. In this research, variations in time detention to obtain the greatest removal efficiency. Additionally, it also will be seen how the differences between each of the processing efficiency of pollutant removal parameters based on variations in the time detention for BOD5 reached 65%, reaching 29.21% for COD and TSS reached 39.50%. The results of these three parameters occurred at the longest time detention, ie 25 hours for anaerobic biofilter and 17.5 hours for aerobic biofilter. Therefore it can be said that the longer residence time in the biofilter treatment processes, the greater the value of removal efficiency that occurs in the BOD5, COD and TSS.
