Domestic demand for petroleum is increasing while Indonesia's oil reserves are running low leading to high world oil prices. To overcome this it is necessary to develop alternative renewable energy derived from vegetable oil, one of which is biodiesel. Purposes of this research were to produce biodiesel from CPO, having study the effect of different weight of the catalyst and reaction time on process of palm oil biodiesel, determine the characteristics of catalyst La/ZnO. The La/ZnO catalyst is made by impregnate 3 % La into ZnO, then dried using oven and calcination, oxidation and reduction. Production of biodiesel is carried out through two stages: esterification and transesterification. The highest yield resulted on La/ZnO catalyst weight 1% which is 92.46%. Production biodiesel from CPO using La/ZnO catalyst produces biodiesel which can be used as alternative energy, catalyst weight and reaction time are directly proportional to the yield of biodiesel from CPO, La/ZnO catalysts have good selectivity against biodiesel from CPO.Keywords: biodiesel, CPO, La/ZnO, transesterification

Total petroleum reserves are declining causing high world oil prices, to overcome this it is necessary to develop alternative renewable energy derived from vegetable oil, one of which is biodiesel. Purposes of this research were to produce biodiesel from CPO, determine the characteristics of catalyst and biodiesel. The La/NZA catalyst is made by activation the natural zeolite, then La is impregnated into NZA having continued variations of 0, 1 and 3% (w/w) of NZA, then dried using oven and calcination, oxidation and reduction. Production of biodiesel is carried out through two stages: esterification and transesterification. The highest yield resulted on using 1%La/NZA catalyst with catalyst weight 3% which is 85.37%. Characteristics of the catalyst that has a surface area and morphology. Biodiesel characterization in accordance with national standards.Keywords: biodiesel, CPO, La/NZA, transesterification

Excessive use of hand sanitizers can cause negative side effects on the skin such as irritation. This is because hand sanitizers on the market are made from alcohol. Therefore, the effort that can be done is by making innovative hand sanitizer products that utilize natural ingredients. Community service activities carried out in Tanjung Berulak Village located in Kampar District, Kampar Regency, Riau Province aimed to provide knowledge about training in making natural hand sanitizers from betel leaves and lime. This activity aims to educate the people of Tanjung Berulak Village, especially PKK women so that they can make their own hand sanitizers at home by utilizing materials available in the surrounding environment such as betel leaves and lime with mixing method. The stages of activities carried out in this service program include the socialization stage, the demonstration stage for making hand sanitizers, and the discussion stage. The implementation of the activity of making natural hand sanitizers was demonstrated directly to PKK women in Tanjung Berulak Village. The number of participants who took part in the socialization was 20 PKK women from Tanjung Berulak Village. The results of the service show that the people of Tanjung Berulak Village are very enthusiastic about participating in the socialization of making hand sanitizers from betel leaf and lime and can practice it in their respective homes.

Batu Belah Village is one of the villages located in the Air Tiris sub-district, Kampar Regency, with residents who mostly have a livelihood in agriculture. To increase the fertility of agricultural soil, fertilizer is needed. So far, the fertilizer commonly used is chemical fertilizer, but the price is relatively expensive, especially during the growing season, so it is necessary to find a solution to replace this chemical fertilizer. Organic solid fertilizer is a fertilizer that is friendly to the environment. This fertilizer can be made from agricultural and livestock waste, so it is very suitable to be developed in Batu Belah Village. The purpose of this activity is to provide knowledge and skills of the community in the technology of making organic solid fertilizer from agricultural and livestock waste. This service activity consists of two stages, namely a presentation on fertilizer manufacturing technology and the practice of making solid organic fertilizer with the farming community of Batu Belah village. The benefit of this activity is that the farming community can make their own organic solid fertilizer from agricultural and livestock waste, so that the cost of fertilizing on agricultural land can be reduced. Thus the income of the farming community can increase.
