Waste Cooking Oil (WCO) is the waste that came from household. WCO become a threat to community because it will come back to food chains again as residual bulk oil that have cheaper price than branded cooking oil. Lintas Winongo Waste Bank in Bumijo, Jetis, Yogyakarta City are trying to manage the waste cooking oil into recycled products. One of their products is aromatherapy candles. However, they had problem to produce the candles and sell it. They also faced problem about the odor of candle that came from WCO as raw material. The purpose of community service were to provide knowledge and skills to produce aromatherapy candles and to calculate the Cost of Goods Sold (CoGS). The methods in this activity were carried out in two stage. The first activity has organized by training and assistance in producing aromatherapy candles that mixed WCO and other ingredients. The second activity focused in calculating CoGS of candles. The results from these community service activities were increased knowledge and skills about producing aromatherapy candles.

Due to the high cost of feedstock and catalyst in biodiesel production, the viability of the biodiesel industry has been dependent on government subsidies or tax incentives. In order to reduce the cost of production, food wastes including eggshells and oyster shells have been used to prepare calcium oxide (CaO) catalysts for the transesterification reaction of biodiesel synthesis. The shells were calcined at 1000 °C for 4 hours to obtain CaO powders which were investigated as catalysts for the transesterification of waste cooking oil. The catalysts were characterized by Fourier Transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), and X-ray fluorescence (XRF) spectroscopy. Reaction parameters such as methanol-to-oil molar ratio, CaO catalyst concentration, and reaction time were evaluated and optimized for the percentage conversion of cooking oil to biodiesel esters. The oyster-based CaO showed better catalytic activity when compared to the eggshell-based CaO under the same set of reaction conditions.

Cooking oil waste that has been disposed could contamine the environment. However, if it is processed well, it can potentially become a raw material of polyurethane. The aim of this study was to determine the best polyurethane on the tensile strength, impact strength, elongation at break, water absorption, characterization of Fourier Transform Infra-Red (FTIR) and the characterization of Scanning Electron Microscopy (SEM). The variables used in this study were ambient process temperature with 440 rpm stirring speed, 1-minute stirring time, the ratio of polyoland WCO was 7:3 (% w/w), and the ratio of Toluene Diisocyanate (TDI) and WCO was 1:1; 1:2; 1:3; 1:4 (% w/w). The results obtained from the analysis of the best tensile strength against the polyurethane synthetic was in the 1:1 ratio of mixed variations between oil and TDI with a value of 0.403 MPa. The best impact strength was in the ratio of mixed variations between oil and TDI with 1:4 (% w/w) with a value of 600.975 J/m2. The best elongation at break against polyurethane foam synthetic was in the 1:3 ratio of mixture variations of oil and TDI with a value of 4.506%.

Waste cooking oil (WCO) can be a useful secondary raw material, if properly managed. On the contrary, uncontrolled disposal generates negative environmental impacts as well as economic loss. Therefore, improving WCO recovery rate, with the cooperation of citizens and effective collection programs, is fundamental. The aim of the study was to investigate the reason for the low recovery of WCO in those areas suffering serious waste management problems such as the Campania region in Southern Italy. For this purpose, the case of a WCO collection program adopted in Angri, a town of around 34,000 people with a high population density, was studied. In 2015, the collection program was managed by a social cooperative, while, in 2016, after the change of the local government, the collection of WCO was entrusted to a private company. In 2015, the households’ participation in the collection program was surveyed through a structured questionnaire. The results revealed that the collection of WCO was practiced by 53% of the respondents. Among those not collecting WCO, 76% of the sample wrongly disposed of WCO in their home (kitchen or toilet). Misinformation was the main reason why they did not adhere to the collection program. Therefore, it was suggested to support information and environmental education campaigns to promote environmental awareness of citizens. Unfortunately, the change of management, together with serious problems in the collection of municipal waste in the whole region, due to the continuous closures of the mechanical and biological plants, produced a sharp decline in the collection from 7730 kg in 2015 to an average of 3800 kg for the period 2016–2019, with a loss of more than 15,000 kg of WCO wrongly disposed with consequent environmental and economic damage. Therefore, information and awareness campaigns are important but the form of entrusting the collection service is equally important, especially in areas with long-standing waste management problems.

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.
