Vegetables Waste Caused By Horticultural Activity In Bandung City

Abstract: Material Flow Analysis was used to assess the amounts of vegetables that introduced into Bandung City and become wastes in every trnasaction chain; grower, supplier, wholesale market, retail, consumer and finally collected into final disposal. A huge amount that produced by the peeling processes raised an idea from Mayor of Bandung to apply a policy „peeled vegetables“ before intoduced into Bandung City. Boundary of the mass flow in this study is Bandung City and functional unit used is a unit of weight (tons). Input data used in this research is the data amount of vegetables that go into Bandung City which is calculated based on the level of consumption of vegetables per capita population of Indonesia, adjusted for the population of Bandung City and the number of people around Bandung City who obtained the distribution of vegetable wholesale market in Bandung. Percentage of waste generated in each transaction chain obtained by observation and experiment in the field, the experiment are artificially at the household level and interviews with actors distribution. The resulting output is the number of vegetables waste in every transaction chain vegetables in Bandung City, either through modern markets and traditional markets. From the analysis it can be seen that the amount of vegetables waste in Bandung is 1,252.38 tons / week or 9.54% of 13,126.02 tonnes of waste generated in Bandung City each week. Keywords: material flow analysis, waste, vegetables, post harvest losses Introduction Vegetables create new problems in the form of waste generated from the sortingprocess prior to sale.The vegetables those are imported directlyfrom agricultural production centers around Bandung like Lembang, Cisarua, and others are notdirectly sold to consumers, but through the processof sorting again-after sorting done at the level offarmers and collectors. The total volume of wasteand waste into these need to be assessed throughthe material flow approach (Material FlowAnalysis, MFA). To reduce the burden of wastewhich is increase every day, the Mayor of BandungCity in 2014 initiated a program of reduction ofvegetable wastes origin, in particular by requiringevery vegetable that goes to Bandung City to bepacked in plastic packaging that is expected toreduce the volume of waste of vegetable origin.Perpetrators of packaging in this case is thesupplier of vegetables which are in the upstreamchain of transactions before entering into Bandung. This study has the objective todetermine the contribution due to the vegetablewaste sorting process (sorting) of the amount ofwaste generated in the markets holding inBandung. The purpose of this study was to obtaindetails of the production of vegetables in the upperlevel (the farm) and the amount of waste generatedfrom the process of segregation of the variousstages of the transaction chain and downstream (markets). Methodology Boundary of MFA systemin this study is Bandung. The waste were analysed only in the form of the number and type ofvegetables waste derived from vegetableproduction (olerikultura) resulting from productioncenters around Bandung City, such as Kertasari,Pangalengan and Ciwidey which are located inBandung. Market which is used as the location ofthe study is only a legally recognized market and isunder the management of PD PasarBermartabatKota Bandung, in terms of which have been 6markets Gedebage Wholesale Market (wholesaler),Andir Market, Kiaracondong Market, CihaurgeulisMarket, Ciroyom Market and Cijerah Market, andmarket that are under management of BadanPengelolaPusatPerdaganganCaringin (BP3C) ieCaringin Wholesale Market. Collection of data14related to waste management from relevantagencies. Data collection was performed by meansof surveys, field trials and interviews with farmers,collectors/suppliers (middlemen), merchantwholesale market, traditional market traders,hypermarkets, supermarkets and for the final stagesof the sorting is done in artificial vegetableconsumers to perform 5 attempts for each types ofvegetables. The survey was conducted by takingsamples from each population.Sampling forfarmers conducted by random sampling method.Data processing approach flow of vegetables waste material is done by analyzing theinput and output to the amount of vegetables andvegetable waste generated in Bandung andsurrounding areas, taking into account othervariables, such as the amount of vegetables thatcome from outside Bandung City. Results Material flow of vegetables and those wastes is shown in Figure 1. Conclussions The vegetables that go into Bandung City through two distribution channels or 2 chain trade system, namely traditional market distribution and modern market distribution. Based on the analysis of material flow to the 22 main types of vegetables consumed in Bandung can be seen that from the input of 5725.99 tons/week of vegetables through traditional markets and 123.56 tons / week of vegetables through modern market generated total vegetable wastes 1252.38 tons / week in Bandung, or 9.54% of the total waste generated 13126.02tons in Bandung City each week from various sources.
