Minyak bekas pakai (jelantah) merupakan minyak tumbuhan yang sudah digunakan untuk menggoreng. Penggunaan minyak bekas pakai mengakibatkan nilai ekonomis minyak tersebut turun dibanding minyak yang belum digunakan. Disamping itu, dengan sifat karsinogenik minyak bekas pakai sangat berbahaya bagi tubuh. Pemanfaatan minyak jelantah belum dilakukan secara optimal, karena banyaknya minyak bekas pakai yang sudah beberapa kali digunakan oleh restoran, kemudian setelahnya hanya dibuang begitu saja, tidak dimanfaatkan untuk produk lainnya. Proses pembuatan pengharum ruangan dari minyak goreng jelantah menjadi alternatif penyelesaian masalah yang patut dipertimbangkan. Pada pembuatan pengharum ruangan, minyak bekas pakai ini digunakan sebagai pengganti natural oil, yakni bahan utama untuk pengharum. Kegiatan pengabdian masyarakat melalui penyuluhan pembuatan pengharum ruangan dari minyak jelantah, dilakukan terhadap Ibu-ibu PKK Perumahan Pamulang Park Residence, Pamulang Barat, Kota Tangerang, Banten. Penyuluhan dilakukan dengan metode ceramah dan demo langsung di depan peserta kegiatan. Hasil yang diperoleh dari kegiatan ini adalah peserta dengan rasa suka cita ikut serta dalam demo kegiatan pembuatan minyak bekas pakai (jelantah) untuk pengharum ruangan. Peserta pun merasa senang karena bertambahnya pengetahuan tentang pemanfaatan minyak jelantah. Harapannya dengan melakukan kegiatan penyuluhan ini, maka Ibu - Ibu PKK pada perumahan tersebut dapat ikut serta dalam upaya meningkatkan daya saing wilayahnya dengan memanfaatkan minyak jelantah. Kata kunci: Limbah Minyak Jelantah, Penyuluhan, Pengharum Ruangan, ABDIMAS, Ibu-ibu PKK ABSTRACT The used oil (waste cooking oil) is a vegetable oil that has been used for frying. The use of cooking oil affects the economic value of the cooking oil lower than unused oil. Besides that, the carcinogenic nature of used oil is very dangerous for the body. Utilization of used cooking oil has not been carried out optimally, because of the amount of used oil that has been used several times by restaurants, and afterward only available just like that, is not used for other products. The process of making room air freshener from used cooking oil becomes an alternative solution to the problem raised. In the manufacture of air fresheners, used oil is used as a substitute for natural oils, which are the main ingredients for fragrances. Community service activities through counseling on the manufacture of air freshener made from used cooking oil were carried out on PKK women in Pamulang Park Residence, Pamulang Barat, Tangerang City, Banten. Counseling was conducted using the lecture and demo method directly in front of the activity participants. The results obtained from this activity were participants who liked to take part in the demonstration of used cooking oil (waste cooking oil) for air freshener. The participants were happy because they were adding knowledge about the use of used cooking oil. It is hoped that by conducting this outreach activity, PKK ladies in this housing can participate in efforts to improve the competitiveness of their region by using used cooking oil.

Waste cooking oil is used oil that has been used for domestic purposes and has undergone changes, both physically and chemically. One effort that can be done to reduce the adverse effects of used cooking oil is changed the material used cooking oil into biodiesel. In this study of biodiesel production from waste cooking oil is done by using biodiesel transesterification reaction as generally through a pretreatment in order to reduce the number of Free Fatty Acid in cooking oil. The high number of Free Fatty Acid will complicate the separation of glycerol from biodiesel so that production of biodiesel will be slight. Test parameters of biodiesel quality produced by  transesterification process refers to the Indonesian biodiesel quality standard ISO 7182: 2015. The production of biodiesel from used cooking oil in this experiment using variations methanol and sodium hydroxide solution ratio to the used cooking oil is 1: 2; 1: 4 and 1: 8. Test results showed that the quality of biodiesel is in compliance with ISO 7182: 2015 on the parameters of viscosity, density and flame test. While the Free Fatty Acids remained above the quality standard ISO 7182: 2015.Keywords :    Waste cooking oil, Transesterification, Biodiesel

The development of biodiesel which is currently increasing has helped increase glycerol as a by-product. The glycerol can be obtained from a transesterification reaction in either vegetable or animal oils or fats and even used cooking oil. Glycerol buildup without further processing can reduce the selling price of glycerol. One solution to overcome this is to convert it to surfactants such as glycerol esters which are widely used in various industries such as chemistry, food, cosmetics, medicine and textiles. This study aims to utilize used cooking oil as a source of glycerol used in the synthesis of glycerol ester surfactants, as well as to compare the quality of glycerol ester surfactants produced by the use of commercial glycerol. The process begins by isolating glycerol from used cooking oil and then purifying it to improve its quality. Then glycerol ester was synthesized by using stearic acid, palmitic acid and oleic acid at reaction times of 120, 150 and 180 minutes. The highest yield of ester glycerol produced was at the reaction time of 180 minutes for each use of fatty acids. The test results showed that the glycerol ester produced was able to reduce the surface tension of the water. The value of hydrophylic-lipophylic balance (HLB) is not much different in the range of 5, and the use of various fatty acids and different sources of glycerol results in % of the stability of different emulsions.

Used Cooking Oil has a negative impact if it is dumped carelessly into the environment and has a positive impact if one of them is used is soap. In this study, corn cobs were used. This soap-making dedication activity aims to provide knowledge to the public regarding the economic potential of used cooking oil waste and corn cobs, skills training for the community regarding the processing of used cooking oil and corn cobs as laundry soap. The method is carried out in two stages: (a) Making soap with used cooking oil and corn cobs. Soap making is done using KOH as a reactant and fragrance to provide an attractive soap product. (b) Training activities for the community. Before and after training measured participants knowledge and attitudes with the questionnaire. The training activities were carried out in Kampung Sawah RW 06, attended by 16 participants. The Data analyzed univariate to see the characteristics of respondents and bivariate with a postwar test to assess the increase in knowledge and test Mc Nemar to assess the change in attitudes. There were increasing knowledge from an average of 3,52 to 4,08 (P = 0,004). Attitude changes also occurred before the training of positive attitudes as much as 43% to 94% after training (P = 0,021). The increased knowledge and attitudes that are statistic significan are expected to increase the increase in good behaviour in the processing of household waste, especially processing the waste oil and corn cobs.

Abstract This article examines young people’s experiences of open access youth work in settings in the UK, Finland, Estonia, Italy and France. It analyses 844 individual narratives from young people, which communicate the impact of youthwork on their lives. These accounts are then analysed in the light of the European youth work policy goals. It concludes that it is encouraging that what young people identify as the positive impact of youth work are broadly consistent with many of these goals. There are however some disparities which require attention. These include the importance young people place on the social context of youth work, such as friendship, which is largely absent in EU youth work policy; as well as the importance placed on experiential learning. The paper also highlights a tension between ‘top down’ policy formulation and the ‘youth centric’ practices of youth work. It concludes with a reminder to policy makers that for youth work to remain successful the spaces and places for young people must remain meaningful to them ‘on their terms’.

In this study, ultrasound was used to accelerate two-stage (esterification–transesterification) catalytic synthesis of biodiesel from used cooking oil, which originally had a high acid value (4.35 mg KOH/g). In the first stage, acid-catalyzed esterification reaction conditions were developed with a 9:1 methanol/oil molar ratio, sulfuric acid dosage at 2 wt %, and a reaction temperature of 60 °C. Under ultrasound irradiation for 40 min, the acid value was effectively decreased from 4.35 to 1.67 mg KOH/g, which was decreased to a sufficient level (<2 mg KOH/g) to avoid the saponification problem for the subsequent transesterification reaction. In the following stage, base-catalyzed transesterification reactions were carried out with a 12:1 methanol/oil molar ratio, a sodium hydroxide dosage of 1 wt %, and a reaction temperature of 65 °C. Under ultrasound-assisted transesterification for 40 min, the conversion rate of biodiesel reached 97.05%, which met the requirement of EN 14214 standard, i.e., 96.5% minimum. In order to evaluate and explore the improvement of the ultrasound-assisted two-stage (esterification–transesterification) process in shortening the reaction time, additional two-stage biodiesel synthesis experiments using the traditional mechanical stirring method under the optimal conditions were further carried out in this study. It was found that, under the same optimal conditions, using the ultrasound-assisted two-stage process, the total reaction time was significantly reduced to only 80 min, which was much shorter than the total time required by the conventional method of 140 min. It is worth noting that compared with the traditional method without ultrasound, the intensification of the ultrasound-assisted two-stage process significantly shortened the total time from 140 min to 80 min, which is a reduction of 42.9%. It was concluded that the ultrasound-assisted two-stage (esterification–transesterification) catalytic process is an effective and time-saving method for synthesizing biodiesel from used cooking oil with a high acid value.
