In order to overcome the disadvantages of conventional method, innovations on how to produce coconut oil were applied with the technique of PENDAWA (Pendayagunaan Asam Jawa). Coconut oil comes from coconut milk which is the substance between oil and water (emulsion). So to get coconut oil, acid is needed as an emulgator to break down emulsifying substances. In this case, Tamarind is used because it is cheap, available, contains a lot of antioxidants, and is efficacious. Coconut oil contains medium chain saturated fatty acids, namely MCT (Medium-chain triglycerides) where MCT provides extraordinary health enhancing properties. We compared three types of coconut oil, namely coconut oil in the traditional way, coconut oil with the addition of tamarind, and packaging oil on the market. The result was coconut oil with the Pendawa method very good in quality and quality with FFA 0.0067% and peroxide number of 1.5 mg ek/kg. In conclusion, this oil production with the PENDAWA method is very effective, efficient, high in quality, and provides high profit for the industry that wants to produce it.

Oil-rich plants are widely cultivated as raw materials for the biofuel industry in developing countries. However, this plant is mainly also a potential source for food supply. Therefore, the supply of food crops and oil competes, making a solution to this conflict very desirable. Technological developments aimed at contributing to an increase in food and fuel supply to meet market demand is the next step in increasing existing food and oil production. Renewable energy is renewable energy and, if managed properly, these resources will not be used up. Renewable energy types include biomass, geothermal, solar energy, water energy, wind energy, and ocean energy. This method promises an economical and environmentally friendly process. Ozone is a strong oxidant for potential use in the degradation process of lignocellulosic materials. This can be produced by air flow through a plasma micro-reactor. Utilization of water as a solvent will produce a solution that is rich in ozone. This research aims to develop a degradation scheme for lignocellulosic materials using an ozonolysis reactor. The novelty of this research is the use of ozone in dissolved water for the degradation of lignocellulosic materials. Water is used as a solvent for ozone dissolving where water molecules with dissolved ozone can be separated into OH radicals which are very reactive oxidants.
