Abstract

Marine plastic waste in Palang Village, Tuban Regency, has caused serious environmental problems, such as water pollution, declining fish catches, and health disturbances due to microplastics. This community service initiative aims to address these issues through the implementation of RECYFUEL pyrolysis technology, which converts plastic waste into alternative energy (diesel) while empowering the Putera Bahari Youth Group. Implementation methods include socialization, technology application training, mentoring and evaluation, and program sustainability measures. The results show an increase in the partners' empowerment level in Management Aspects (100% of partners mastered waste management and financial reporting), Production Aspects (90% of partners were able to independently produce diesel), and Marketing Aspects (90% of partners were able to market diesel products to local fishermen). A total of 50% of plastic waste was successfully processed into diesel, with a conversion rate of 1 kg of plastic yielding 300–400 ml of diesel, along with the creation of a new profitable business opportunity. This program not only reduces environmental pollution but also enhances the economic income of the community. Thus, RECYFUEL technology proves to be an effective and sustainable solution for plastic waste management and the empowerment of coastal communities

Abstract

Pioneer plants are plants with high adaptability, so they can grow in disturbed environments, such as ex-limestone mining areas. This adaptability is supported by the ability of these plants to associate with soil bacteria in their rhizosphere area. The presence of these bacteria can support the growth of pioneer plants on disturbed land. The purpose of this study was to characterize the soil bacteria around the rhizosphere of pioneer plants in the former limestone mining areas. Soil samples in the rhizosphere area of 5 pioneer plants from ex-mining lime were then isolated using the Pour plate method to obtain bacterial isolates. The bacterial isolates obtained were then identified their colony morphology. Based on the results of colony morphological identification, 21 isolates were obtained from the rhizosphere of 5 pioneer plants from the former limestone mining area. The highest number of isolates was obtained from the rhizosphere of the Waltheria indica with 9 isolates, 8 isolates of each Lamium barbatum and Digitaria sanguinalis, 7 isolates of Chromoleana odoratum, and 5 isolates of Tridax procumbens.
