Social welfare can be improved in various ways that can be done, for example, through communityempowerment programs. The part of the community that can be empowered are housewives who aremembers of the PKK organization, especially in Wangen Village, Polanharjo District, Klaten Regency. Theimpact of environmental pollution is due to the disposal of used cooking oil and is followed by an increasein the use of cooking oil due to the appeal to stay at home during the Covid-19 pandemic. The existence ofthis makes a training program and assistance for the utilization of cooking oil waste into soap is the rightthing to deal with this problem. The specific goals and targets to be achieved in this activity are that PKKmothers are interested and motivated to become entrepreneurs, to form groups of PKK members whobecome economically independent by producing soap. In order to achieve this goal, a community serviceprogram was carried out by a lecturer at the University of Duta Bangsa Surakarta who provided soapproduction training conducted by PKK women in Wangen Village. The result of this service is an increasein the skills of PKK Village women in Wangen in making soap from used cooking oil waste.

The area around of Jember University has potential as a trading area because the majority of its citizens are immigrants. This potential is utilized by street food vendors located around the University of Jember. Most street vendors dispose of waste i.e used cooking oil directly around trading locations. One methode to determine waste seepage in the soil is to use the geoelectric method with crosshole dipole-dipole configuration. This research is a laboratory scale research. The sample of soil and waste of used cooking oil were taken from the location of street vendors around Jember University. Based on the research results, the soil resistivity value before being given the waste is 2.78 Ωm to 7.52 Ωm. While the value of soil resistivity after given the waste of used cooking oil ranged from 0.01 Ωm to 5.15 Ωm. Observations from the first day to the seventh day indicate that the movement of waste used cooking oil occurs vertically due to gravity and in all directions due to capillarity.

To slow down the spread of the Coronavirus, the population has been instructed to stay<br>at home if possible. This measure consequently has a major impact on our daily mobility<br>behaviour. But who is being affected, and how? The MOBIS-COVID-19 research project,<br>an initiative of ETH Zurich and the University of Basel, is a continuation of the original<br>MOBIS study. The aim of the project is to get a picture of how the crisis is affecting<br>mobility and everyday life in Switzerland.

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.

Abstract Background Many community-dwelling older adults experience limitations in (instrumental) activities of daily living, resulting in the need for homecare services. Whereas services should ideally aim at maintaining independence, homecare staff often take over activities, thereby undermining older adults’ self-care skills and jeopardizing their ability to continue living at home. Reablement is an innovative care approach aimed at optimizing independence. The reablement training program ‘Stay Active at Home’ for homecare staff was designed to support the implementation of reablement in the delivery of homecare services. This study evaluated the implementation, mechanisms of impact and context of the program. Methods We conducted a process evaluation alongside a 12-month cluster randomized controlled trial, using an embedded mixed-methods design. One hundred fifty-four homecare staff members (23 nurses, 34 nurse assistants, 8 nurse aides and 89 domestic workers) from five working areas received the program. Data on the implementation (reach, dose, fidelity, adaptations and acceptability), possible mechanisms of impact (homecare staff's knowledge, attitude, skills and support) and context were collected using logbooks, registration forms, checklists, log data and focus group interviews with homecare staff (n = 23) and program trainers (n = 4). Results The program was largely implemented as intended. Homecare staff's average compliance to the program meetings was 73.4%; staff members accepted the program, and particularly valued its practical elements and team approach. They experienced positive changes in their knowledge, attitude and skills about reablement, and perceived social and organizational support from colleagues and team managers to implement reablement. However, the extent to which homecare staff implemented reablement in practice, varied. Perceived facilitators included digital care plans, the organization’s lump sum funding and newly referred clients. Perceived barriers included resistance to change from clients or their social network, complex care situations, time pressure and staff shortages. Conclusions The program was feasible to implement in the Dutch homecare setting, and was perceived as useful in daily practice. Nevertheless, integrating reablement into homecare staff's working practices remained challenging due to various personal and contextual factors. Future implementation of the program may benefit from minor program adaptations and a more stimulating work environment. Trial registration ClinicalTrials.gov (Identifier NCT03293303).
