Abstract

The lack of knowledge and skills of the weaver community in Amol Village, North Central Timor Regency to prepare natural dye from natural resources that are difficult to be found in dry season is the main reason to conduct this service activity. This training was aimed to improve the knowledge and skills of the weaver group and providing them indigo paste as a natural color stock that can be stored and used during dry season. Service activities were carried out through 2 steps, namely counseling and training, which begins with a demonstration by service team and then continues with independent practice while being accompanied by the team. The knowledge of the weaver group to extract natural dyes from natural resources has been improved, as evidenced by the evaluation results. Members of the weaver group became more skilled in preparing indigo paste from Indigofera tinctoria leaves. At the end of the activity, indigo paste products were obtained which were applied to Timor woven fabric.

Abstract

Waste cooking oil is heated at a high temperature of 160-250°C for a long time, causing oxidation, hydrolysis, and polymerization to produce ketones, aldehydes, and polymers that are detrimental to human health. Therefore, it is not recommended for reuse. Waste cooking oil in Amol Village was abundant and accommodated, often used repeatedly and then dumped into the environment without any further treatment. The initial survey showed that most of Amol Village's people do not yet know about the dangers of reusing used cooking oil or the dangers to the environment. On the other hand, high free fatty acids have the potential to be converted into soap through the saponification process with a base. Thus, the socialization of the dangers of waste cooking oil for human health and the environment and training on making solid soap from used cooking oil was carried out in Amol Village to assist the community in dealing with used cooking oil waste and save spending on soap purchases. Problem-solving was carried out through several stages of activities, namely observation, preparatory activities, socialization; manufacture of solid soap product from used cooking oil. Those stages were carried out through demonstrations and practices independently by participants, followed by monitoring, evaluation, and reporting. The knowledge and skills of participants have been improved, regarding to handling the used cooking oil and its processing into solid soap.
