Abstract

Infrastructure Improvement which is located on Jl.Tumbang Talaken - Jl.Tumbang Jutuh with a length of 40,920 meters and a distance of 141 km to the capital city of Palangka Raya. The condition of the remote location and the fluctuating price of diesel fuel will require large costs. While around the project is an oil palm plantation and the waste is piling up. If left untreated, palm shell waste will have a negative impact and cause disease, by utilizing palm shell waste as a dryer heater in Hotmix production as a substitute for diesel fuel with the hotmix production cost efficiency analysis method on AMP so that it can reduce production costs in the project. The results of the analysis of validity and reliability show that production by gasifying palm shell waste is feasible to replace diesel fuel. The results of the BEP analysis, that the use of shells as a substitute for diesel fuel has great potential to reduce production costs, when hotmix production is at a volume of 3,826 tons. So, with a planned hotmix production volume of 22,667 tons, it is feasible to procure or invest in shell combustion equipment. Suggestions from this study that replacing dryers with palm shell waste material as a substitute for diesel fuel can be done if the road infrastructure development project is around oil palm plantations, because in addition to being able to reduce hotmix production costs on AMP it is also an environmentally friendly waste management because it has no impact negative on the environment. If the project is not located in the vicinity of an oil palm plantation, then the use of palm shell waste as a substitute for diesel fuel needs to be further researched because the efficiency value will be different

Traditional market is the place which represents the transaction between sellers and buyers. However, by the development of the period rapidly, the existence of traditional market begins to be threatened. It is because the proliferation of retail business from foreign funds, for example is Minimarket. Due to the proliferation of the Minimarket, people has been prefer to visit Minimarket rather than traditional market. Clean place and free from the word of dirty have made visitors more comfortable to visit Minimarket. And this condition is in opposite with the traditional market which seems slum, muddy and far from hygienic. This situation has succesfully made the traditional market left behind of the modern market. This research aims to know the characteristic of location of the traditional market and its operational impact and recommend the traditional market model. The model of market location can enhance the competitiveness of traditional market with modern markets. As for which becomes the object of this research are, traditional market data that listed in the Market Service of Semarang city, that market conditions are obtained by means of direct observation or interviews to the merchant market, the market manager and the buyer's market. As for the secondary data used is DED of market, the number of market stalls, number of floor los data, data number of traders, market land area data, and data market building area. The conclusions of this research was obtained some variables from location factors that affect the success of the revitalization, covering a distance of main street market, broad visibility, parking lots, the amount of market traders, the number of entry to the market, and the number of transport towards the market. As for the success of the revitalization of the market was also influenced by his market in the populous region. Because there is still no recommendations placement location a strategic market, for it is this research make a model of market location recommendations and a population density of traditional market.
