AUTO2000 Basuki Rahmat is one of the branches dealer Toyota, which is located in the city of Surabaya, is engaged in services such as sales, maintenance, repair and supply of Toyota spare parts whose management is fully handled by the Astra Group. The company always strives to provide fast and accurate service, but customers spend quite a long time waiting because the car service process is relatively long. The long service time is caused by an unorganized operational system that causes waste (waste). Based on these problems, it is necessary to analyze Basuki Rahmat's car service services at AUTO2000 using the concept lean service by using the method value stream mapping, fishbone, and 5 whys. The research results obtained weight waste motion or transportation of 0.1481; waiting or delay of 0.1325; incorrect inventory of 0.1273; lack of customer’s focus of 0.1195; defect of 0.1065; duplication of 0.0935; overproduction of 0.0779; unclear communication of 0.0675; underutilized employees of 0.0675; And variation of 0.0597. Research recommendations that can be proposed to reduce waste including repairs layout, adding monitors on the service floor for matters of sending and receiving information, increasing the number of mechanics, making plans booking with different hours, making and applying the system tracking of the presence of the tool. Therefore, lead time the initial service service process of 170 minutes becomes lead time 128 minutes.

Waste problems that have not been resolved so far have also been experienced in the Tanjung Market area, Jember Regency. The waste problems at Tanjung Market are an ineffective management system, the accumulation of waste that is not sorted into one, and the absence of a special party assigned by the market manager to handle and control hygiene problems and waste in the market which causes a lot of waste to be scattered around the market. everywhere. Not only from the traders side but this is also caused by the visitors or buyers at the market, most of them do not have the sensitivity and awareness to be able to dispose of waste in its place. So we need an environmentally sound waste management system with 3R techniques such as converting waste into useful materials efficiently and economically with minimal environmental impact.

Efforts to reduce the use of polluting chemicals environment needs innovation to overcome these problems. One of them is by replacing the chemicals contained in the battery by utilizing mango skin waste became bio-battery. Even mango skin waste in the community is not properly utilized so that mango skin becomes waste that has no value. The purpose of this research is to utilize mango skin as a bio-battery material not only to produce current and voltage sources but it is also expected to be able to reduce the negative effects of disposing of community mango skin waste residue into the environment and reduce dependence on chemicals as battery electrolyte paste which has been used so far. The test parameters carried out were the electricity of the bio-baterry using mango skin and salt samples. This research used 3 weight ratios between mango skin solution and salt solution, namely 15:5 gr, 20 gr:5 gr, and 25:5 gr. The main stages of this research consisted of 3 stages, namely preparation, pH testing, characterization of electrical properties, and electrical analysis of mango skin. The results of the research that has been done, it can be concluded that the smallest measurements of pH, electric voltage, and electric current are produced at a volume of 30 ml (15 gr) of 3.55, 0.53 V, and 1.8 mA. While the highest was produced at a volume of 44 ml of 3.53, 1.53 V, and 1.9 mA.
