Abstract

Solid waste from “agar-agar” (gelation made of seaweed) factory in huge amount and has potency to pollute the environment if it is not well managed, obviously has opportunity to be used as compost. The purpose of this research is to find out the characteristic of composting process of agar-agar factory’s waste, and the quality of its compost product,based on 2 ( two ) treatments i.e. with and without the use chicken manure starter. In general, result of the research showing that there is no significant different between using chicken manure starter and not using chiken manure starter, with understanding that both composting process can be done in aerobic condition (normal) with compost quality according to mature compost criteria. However, specifically the rate of waste decomposition (composting process) of using chicken manure starter looks faster in initial period of decomposition.Key words : compost, “agar-agar” factory waste, chiken manure starter.

Abstract

The objective of this study was to utilize the superiority of agricultural waste in form of soybean hull and shrimp wastes and their combination on egg layer duck. This feed contains starbio probiotic functions for fiber digestion (soybean hull waste) and chitin (from shrimp waste). The expectation was that there would be duck ration which is able to increase egg production and quality and brighter reddish egg-yolk which is attractive and full of nutritions. The research was conducted in three stages. Stage I is Nutrient Digestional Value Test on the formula of soybean hull and shrimp wastes mixture on Duck Feed Contained Starbio." Stage II : experiment on "Mixture Formulation of soybean hull and shrimp wastes mixture on Duck Feed Contained Starbio Probiotik for Increasing The Performance of Egg Layer Duck" and III experiment on "The Production of Reddish Duck Egg-Yolk With Feed Contained soybean hull and Shrimp Wastes Mixture". The experiment concluded that : I) the provision of soybean hull andshrimp had significant effects on digestability of feed dried materials, but conversely had no effects on protein digestability and crude fiber, as well as on egg produktion and quality.There was no interaction between two materials in the treatment. 2) Shrimp waste tended to have effects on daily egg production of egg layer duck; 3) Yellow color of the eggs couldn't change to be reddish yet, since xanthophyl content had already lost in over-dried and alreadyexpired shrimp wastes.Key Words : shrimp waste, soybean hull, probiotic, egg-yolk color

Abstract

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

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

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

Abstract

Mercury (Hg) which is contained in aquatic ecosystem can enter and be accumulated to organism’s body, like on petek fish (Leiognathus equulus). The research aimed to see mercury concentration in aquatic ecosystem, to see mercury concentration in organ of petek fish by AAS (Atomic Absorption Spectrophotometer) and its histopathology response in organs of petek fish. The research was done at Ancol, Jakarta Bay on October-December 2004. There are 16 samples of water and fish from 3 stations.The analysis result of water quality is compared by standard quality of sea water for sea organism life (Kepmen LH No. 51, 2004), mercu ry concentration in fish organ is compared by maximum mercury concentration in fish body by classification of Palar (2004). Ancol water quality is still on normal condition. Mercury concentration in water and petek fish organs had low concentration. Gill and lever contaminated by mercuryis only in station 1 fish, but it is still on normal concentration. Histopathology of petek fish gill is not abnormal, while the lever is necrosis. Water and petek fish is not a good indicator to detect mercury in aquatic ecosystem.Keywords: mercury, petek fish, water, lever, gill, histopathology, accumulation,indicator

Abstract

Pollution in the rivers is generally caused by domestic and industrial waste. Some treatments to solve it can be done individually or collectively. The effort can be physical, chemical, or biological treatments chosen by its form, character, kind, quality, quantity. PT Van Melle Indonesia is a candy company which produces a high biological waste with COD concentration 10000-30000 mg/litre. This paper reports activated sludge reactor performance to decrease the waste’s organic content. The reactor is a biological waste water treatment, as a sequence of earlier anaerob process which still has a high COD (700-4000 mg/litre). A continued reactor operation done with retention time variation 24 hours, 18 hours, 12 hours, and 6 hours show reduced COD varied 80-90%. The highest efficiency was 97.59% from the 24 hours retention time, and the lowest efficiency was 89.5% from the 6 hours retention time. Keywords: activated sludge reactor, candy industry wastewater
