Abstract

Like other Cities in Indonesia, Kota Probolinggo also faces municipal solid waste problems. To overcome it, Kota Probolinggo is trying to do activity of garbage recycle at household scale and also in neighbour scale. One of the efforts is converting it to become organic fertilizer with a good quality, a real fertilizer required by the farmers to improve soil fertility which becoming decreases. To support the activity, in year budget 2008/2009, Pusat Teknologi Lingkungan - BPPT has done a disemination technology of Accelerated Revolver Windrow Composting (ARWC) for optimization of composting which have been done in Kota Probolinggo. Technology ARWC was developed by BPPT which has been checked and tested. Technology ARWC is fermentation system of organic garbage done aerobically by the way of heaped (windrow) and revolved regularly, turns into stable matter like humus in accelerated time. The product is compost, either in the form of ordinary compost and also compost granule, with a good quality and fulfi lls national standard. Processing activity of garbage becomes organic fertilizer has opened new employment and increases management system effi ciency and lengthens TPA age.Key Words: Municipal solid waste, Composting

Abstract

Application of chemical fertilizer without adding organic mater causing land poor in nutrients and low of microbial diversity. It causes dedradation of land fertility. This situation can be solved by applying of compost. Nevertheless, macronutriens content of compost are low, it has advantages such as improving physical soil properties, soil permeability, porosity, structure, water holding capacity, etc.Compost application effect is depend on the type of plant and physico-chemical properties of soil, compost characteristics, doses and time of compost application. Compost aplication is agronomically and economically benefit for farming activities that is in line with the organic farming.Key words: Compost, fertilizer, agricultural

Abstract

Proses pembakaran sampah kota melalui insinerator akan menghasilkan uap panas yang bisa dimanfaatkan  untuk membangkitkan energi listrik, akan tetapi pada proses ini juga menghasilkan output berupa flue gas yang didominasi oleh partikel (fly ash) dan gas beracun seperti: HCl, SO2, NOx, HF, Hg, Cd dan Dioxin. Sebelum dibuang ke udara bebas, flue gas tersebut harus diolah agar memenuhi baku mutu lingkungan. Teknologi penanganan partikel dan gas polutan tersedia dan dapat dibuat dengan berbagai kapasitas. Untuk menangani flue gas dari insinerator sampah digunakan Quencher untuk menekan laju pembentukan kembali dioksin dan furan setelah proses pembakaran,  Spray Drying Absorption (SDA) untuk mengikat gas asam dan  logam berat serta bag filter untuk menangkap partikel. Selain itu digunakan ID Fan dan Cerobong Asap untuk pengatasi pressure drop yang terjadi akibat pengoperasian peralatan APC dan melepas ke udara.

Abstract

The end of municipal solid waste operations is landfill. Almost all of the Indonesia city’s landfills use the open dumping system. Generally, wastes dumped in the landfill are dominated by organic materials that potentially used for cow feeding. So that, in some landfills there are cow pasturing with the low cost operation related to the free feeding materials. According to UU No 18/2008, in the year of 2013 open dumping landfill is prohibited operate changed by sanitary landfill. Related to this change, the cow pasturingin landfill will be affected. So that the cow pasturing in landfill need to be assessed in the aspect of waste reduction, economic values, landfill operation, social conflict, and safety cow meat. The goals of this study are assessing positive and negative impacts from cow pasturing in the Piyungan Landfill, Yogjakarta. Research methods used are references study, interview, counting the cow and direct investigation of landfill operation. This study concluded that cow pasturing in landfill has positive impacts for waste reductionand increasing economic level of people live in surrounds of landfill. Unfortunately, the cow pasturing has also negative impact such as disturbing daily landfill operation, high potent social conflict during landfill rehabilitation, and high content of some heavy metals in the cow organ. Based on those impacts, the policy of the cow pasturing has to be reviewed because of the importance of sanitary landfill operation in the near future andthe issue of safely consuming meat free from heavy metals.Key Words: landfill, waste, cow pasturing

Abstract

The goal of this research is to study the dynamics changing of temperature, weight and volume of wastes during composting process in Cakung Slaughterhouse. The composting process was done using windrow system for 65 days. Windrow was turned mechanically using compost turning machine once a week. Composition of input wastes was calculated based on its volume and specific weight. Regularly, windrows were measured of their volume, weight and temperature. The composting shows that weight and volume reduction was exponentially done in the two of the first weeks. The temperature also exponentially increased in that time. Those indicated that the increasing of metabolisms and development of microbiology during composting process. Weight and volume reduction reached about 80 percent, and their temperature reached above 55oC during first weeks. The dynamics changing of the temperature and volume/weight reduction was the key parameter for evaluating composting process.

Abstract

The application of high technology (hitech) for solid waste management andtreatment in Singapore is one of examples of solving the municipal solid waste problem. Singapore with more than 4 million inhabitants produced 7676 ton wastes per day in 2001. Now, all the combustible solid wastes goes to the incinerator plant that can convert the heat into electricity. The ash from incinerator and the incombustible solid wastes are transported via waste harbour in Tuas to the Semakau off shore landfill. Also, before incinerating in the plant, the activities of collecting and transporting of munocipal solid wastes are suported by such kind of new technologies for example pneumatic refuse transport system. The typical of the high tecnology is need high cost for building, operating and maintaining and should be operated by high skill staff. Singapore has all the need and also has a strong political will in combating the solid waste problems. So that, Singapore is one of the cleanest metropolitan cities in the world.

Abstract

ABSTRACTHigh population growth rate has stimulated the increase of energy consumption. Therefore, the use of renewable energy sources such as methane gas from landfill has also been encouraged. It is necessary that landfill methane gas is purified to increase its concentration. Common method to purify methane gas is water scrubber method. The aim of this research was to evaluate the effectiveness of landfill methane gas purification using a spray water scrubber (water scrubber method), a water column scrubber (bubbling methods) and the combination of both methods to increase the content of landfill methane. The experiment was conducted in the dry season and rainy season. Results of the study concluded that water scrubber was the most effective method for increasing methane gas concentration. The average increase of methane gas in the dry season were 33.32% (water scrubber) and 23.79% (combination of bubbling and water scrubber), and in the rainy season 8.89% (water bubbling) and 2.75% (combination of water scrubber and water bubbling). The increase in methane gas was due to a decrease in CO2 gas. In addition, there was an increase of H2O content in biogas from landfill after the purification process.Keywords: Landfill, methane gas, purification, water scrubberABSTRAKTingginya laju pertumbuhan penduduk telah memacu konsumsi energi yang terus meningkat.
