PENGHITUNGAN EMISI GAS RUMAH KACA (GRK) DARI SEKTOR SAMPAH PERKOTAAN DI INDONESIA
Authors: Purwanta Wahyu
Published: January 2019

Indonesia produced 48.8 Mt/year of Municipal Solid Waste (MSW) with populationnumber of 218.8 million and rate of waste generation 0.61 kg/cap/day. Most ofMSW (40%) are transported to the Solid Waste Disposal Site (TPA) in urban area.The landfill site which is unmanaged will become a source of the GHGs emission,mainly the methane emission. Based on the Indonesian population, using FODIPCC Tier-2 method, CH4 generated from MSW sector (landfill only) in 2006 is109.96 Gg CH4 and will be increased up to 259 Gg in 2010, 504 Gg in 2015 and1,065 Gg in 2025. The increase number of this CH4 emission is caused by theincrease of population number that will increase the waste production and alsoincrease the volume waste that is collected in the disposal area. The future scenarioby referring to the national strategic plan which is developed by the Public WorkDepartment is that the waste should be reduced from the source, so the totalvolume will be reduced by 20% in 2010. In 2015, refers to the MDGs target, 80% ofthe MSW in urban area and 50% of the MSW in rural area should be transported tothe final disposal site. As stated in Solid Waste Management Act No 18/2008 andin accordance with the raw water protection, improvement of landfill quality fromopen dumping to sanitary landfill or controlled landfill and development of regionallandfill are the priority programs with national financial support as an initial investment.

In the last ten years Indonesia has already developed more than 15 CrudePalm Oil Factories (CPOF). Unfortunately the major of them do not have properwastewater treatment plants (WWTP) yet. General speaking that in Indonesia thepalm area has been increasing rapidly. Because of the very large palm area, almostall CPOF use a large area for the WWTP and the main processes of WWTP areanaerobic and aerobic system using large ponds as lagoons. The most environmentalproblems appear such as the bad quality of the effluent from WWTP and inmaintaining units of the WWTP. The aim of this assessment is to compare theWWTP belong to 3 CPOF (PT. Kertajaya, PTP Nusantara IV Bah Jambi and PT.Smart Tbk) and RANUT as a research product from Palm Research Center locatedin Medan. Wastewater (produced by CPOF) used for Land application is alsodiscussed and it is well known in using the wastewater to fertilize the palm plantation.A recommendation for the wastewater treatment system has been proposed. Thesystem has eight processes including oil separation or first sedimentation,neutralization, equalization, anaerobic degradation, aerobic degradation, finalsedimentation and sludge drying.

Cassava peels is one of agriculture waste having potency as feed for poultry. Cassava peels represent waste product from cassava industry with amount 1,998 million ton in the year 2006 in Indonesia (10 percentage of corm of yielded cassava). The weakness of cassava peels are low crude protein content, less palatable for ruminant and have voluminous characteristic. One of the effort to increase usefulness of cassava peels is by using cassava peels as fibre source in pellet complete ration for poultry. The aim of this research was to know best level from utilization of cassava peels as physic quality in poultry complete ration. This study used Completely Randomized Design that consistsof three treatments and three replications. The treatments were: 1). Control feeds + 0% cassava peels (R1), 2). Control feeds + 30% dry matter cassava peels (R2), 3). Control feeds + 30% boiling matter cassava peels (R3). Data was analysed with ANOVA and continued with Duncan Test. The result indicated that effect of water content pellet ration with moisture tool is higher than using infrared tool. Pellet rations with dry matter and boiling matter control treatment before saving have physic qualities that still meet the quality standar of poultry ration. Eventhough, on treatment after saving, the physic qualities decrease and relatively less meet the quality standar of poultry rationKey word: waste, cassava peels, poultry ration, pellet complete.

Presl (Eceng) for Hg phytoextraction on paddy field contaminated with Hg from illegal mining. The plants were grown on contaminated media from paddy field in Pongkor (68.269 ppm Hg) added by NPK fertilizer (0, 3 and 6 g/pot) and ammonium thiosulphate chelating agent (0, 20 ppm). The result showed that the growth of kiambang,eceng, genjer and padi are significantly different. Chelating agent did not significantly affect the plant growth, meanwhile fertilizer significantly affected the plant growth. Thetreatments resulted in different Hg concentration in the plants. Fertilizer increased plant biomass and so plant Hg content since Hg contents is a function of total biomass and Hg concentration. It can be concluded that based on the criteria of accumulator plant,kiambang is the most potentially Hg accumulator followed by genjer and eceng.Key words: Phytoextraction, Hg, Salvinia molesta, Limnocharis flava, Monochoriavaginalis

In general, coastal areas have the physical and chemical properties of lessfertile land with an extreme dry climate, so that only a few plants that can live,including Jatropha curcas L. To enhance fertility and improve soil physicalproperties, need the addition of organic fertilizer. Source of compost canbe derived from a variety of wastes, including household waste and landfill.Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organic C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfill has an obstacle in the form of heavy metal containing high Cu and Pb. To prevent accumulation heavy metals into plant tissue or clean up heavy metals from the soil it was attempted by phytoremediation using jatropha plantation and bio-fertilizer that contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biological fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) Biofertilizers could inhibit the accumulation of copper (Cu) and lead (Pb) into Jatropha curcas L., (3)Jatropha plant can be classified as phytoremediation plants, because it can absorption heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals

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
PEMANFAATAN DIMETHYL ETHER (DME) SEBAGAI SUBSTITUSI BAHAN BAKAR MINYAK DAN LPG
Authors: Boedoyo Mohamad Sidik
Published: January 2019

As a developing country, currently the energy demand in Indonesia increases rapidly.Although Indonesia has a huge of oil reserves the production of oil fuels as the main energy consumption has not been enough and should be imported. It is devised to substitute oil fuel with other resources such as liquefied coal, natural gas, biofuels and dimethyl ether (DME). In the short future, the use of DME as an alternative fuel appears to be a promising approach for reducing the uses of diesel oil and LPG. It can be described in to two approaches. First, due to the high cetane number of DME, it can be used for compression ignition engines which have higher thermal efficiencies compared to spark ignition engines. Second, due to the physical properties of DME, it can substitute oil fuels and LPG uses in industries, commercials, and households for lighting and cooking. Hence, DME production is not limited to one feedstock. DME canbe derived from fossil fuel feedstocks, including natural gas and coal, as well as from renewable feedstock sources such as biomass. Since Indonesia have abundant of energy sources as DME raw material, such as natural gas, coal and biomass, utilization of DME into Indonesia energy system is necessary to be developed.Key words :Energy Potential, Dimethyl Ether, Diesel Oil and LPG Substitution
