Abstract

Energy needs are increasing, while the energy sources used so far have come from petroleum, natural gas and coal (fossil fuels) which are non-renewable and the amount always decreases from time to time. Energy sources derived from renewable fuels are a solution to this problem. One type of product from renewable energy sources derived from vegetable oil is biodiesel (methyl ester). Biodiesel is a monoalkyl ester of long chain fatty acids contained in vegetable oils or animal fats for use as diesel engine fuel. The implementation stage of this activity begins with the preparation of raw materials in the form of preparation of used cooking oil and filtering. The second stage is dissolving caustic soda (2-3 g) into methanol liquid (5:1 methanol water). The third stage is mixing the oil with a solution of methanol and caustic soda into a bottle and allowed to stand for 24 hours, this stage aims to separate the glycerol content in the oil. The fourth step is to separate the oil with solid glycerol and transfer it to an empty container to be mixed with warm water, this aims to remove excess methanol liquid in the oil, let stand for 24 hours. The last step is to separate the oil from the mixing water. From the results of this experiment, a ready-to-use biodiesel liquid was obtained.

Abstract

Lake Tirta Gangga is an artificial lake located in Central Lampung Regency, Seputih Banyak District, precisely in Swastika Buana Village. This lake has an area of ​​about 150 hectares and is used by the community for irrigation of about 3000 ha of agricultural land around the area. Lake Tirta Gangga has its own charm for local tourists to enjoy its natural beauty and scenery. However, some community activities cause the aspect of natural beauty to be reduced and cause problems in the supply of raw water for agriculture. So we need an action that can maintain the initial function of this lake and even add economic value to the community. This service aims to overcome these problems by mapping the potential of new geotourism that can be developed and managed by the community, educating the community in improving the quality and excellence / local wisdom which has an impact on increasing the economic value of the Tirta Gangga Lake area by utilizing information technology for media promotion (with drones) profile of the Lake Tirta Gangga tourist area. The benefits of this service are the mapping of new geotourism potentials that can be developed and managed by the community as well as the formation of video promotion media for the profile of the Lake Tirta Gangga tourist area which can be disseminated through internet media so that tourists can easily recognize and be interested in visit Tirta Gangga Lake.
