Micro-enterprises in the community still need a helping hand in the form of a service program from the campus. It is known that the micro-enterprise community belongs to the lower middle class, so there is still a lack of interest in seeking information/literacy and this results in the absence of business development in the future in a better direction. In Karanganyar Village, Poncokusumo, Malang, a fiber business was found in the manufacture of tools made of plastic, this business has been running for 3 years and there is still no high enough development. In addition, another problem is the problem of fiber waste that has not been utilized at all. There was no processing or conversion into useful and economically valuable materials. The solution offered is the manufacture of organic pots/growing media. The method of implementing this service used three stages, namely preparation, implementation, and reporting. The data collected in the form of documentation, observation, and the results of filling out the respondent's questionnaire which was then analyzed descriptively qualitatively. The results of the service showed that organic growing media from fiberglass can be applied and attract partners' interest. Knowledge of occupational health and safety has enthusiastically educated partners. The results of the partner satisfaction questionnaire showed that this service activity has a very satisfied response category of 65.7% and a satisfied response of 34.3%. So, WBS fiberglass partners have received, supported, appreciated, and followed this service well.

Biodiesel is still being developed as a renewable fuel to replace a diesel fuel. Biodiesel production of castor oil has high potential because the oil did not compete with foods. Furthermore, a transesterification process can be optimized by heterogeneous base catalysts. Thus, this study aims to: (1) synthesize CaO/K2O catalysts to be used in the transesterification process, (2) synthesize biodiesel of castor oil and characterize it according to SNI 7182:2015, and (3) study the effect of CaO/K2O variations on biodiesel product. This laboratory experimental research was carried out in the following stages: (1) characterization of castor oil, (2) esterification, (3) preparation of CaO/K2O catalyst, (4) transesterification, and (5) characterization of the synthesized methyl ester. The results showed that the characterization of castor oil included a density of 1.074 g/mL, an acid number of 9.5 mg/g, a free fatty acid (FFA) of 5.09%, and a viscosity of 701 cSt. Stratified esterification and transesterification showed a significant effect on reducing FFA, so the characterization of the transesterified methyl ester from the best catalyst variations (CaO/K2O 1:2) included a density of 1.016 g/mL, an acid number of 1.1 mg/g, FFA content of 0.58%, moisture content of 1.1%, viscosity 43.55 cSt, and refractive index (25) of 1.466.

Youth life is closely related to spiritual activity. The phenomenon that is still encountered is Hubbu Ilahi, or the love attitude of Allah SWT. This phenomenon is presumed that adolescents only state and do not know the consequences of their attitudes. So, this study aims to determine the perceptions of today's adolescents on the phenomenon of Hubbu Ilahi. This research is descriptive qualitative research with a survey research method. This study used a purposive random sampling technique to 39 adolescents. Data collection used a questionnaire with the google form platform. Then, the data were analyzed using: data presentation, data reduction, and concluding. The results showed that adolescent respondents stated the consistency of love of the Quran, love of Rasulullah (SAW), love of the Prophet's Sunnah, and love of the Akhirat life. However, the busyness of the world blocks the proven proof of love. The analysis concluded that only 7.7% of adolescents fit Hubbu Ilahi's criteria.
