This article aims to determine the level of anthocyanins in natural colors derived from dragon fruit, especially on the skin. Completely Randomized Design (CRD) with SPSS was used as the research method for this article, as well as two treatments, namely variations in solvent volume A and immersion time (B). Each treatment consisted of three levels and three repetitions, namely the first factor of variation in solvent volume (A) consisted of (A1) 0.29%, (A2) 0.432%, (A3) 0.576%. The second factor is the immersion time (B1) 42 hours, (B2) 48 hours, (B3) 72 hours. Extraction of anthocyanin pigment from red dragon fruit skin was carried out using maceration extraction. The test parameters in this study were the color stability test, anthocyanin content test and the yield of dragon fruit peel extract. The pH value was measured using a pocket pH meter. In this study, a spectrophotometer was used to determine the brightness level of anthocyanins. Measurement of the weight % yield of anthocyanin pigment was carried out using the yield formula below. The research results show; (1) the best treatment resulted in extraction using citric acid solvent: water which produced an absorbance of 0.479 – 0.439 at λmax 517 nm; (2) radar antioxidant activity in anthocyanins from dragon fruit peels of 76.71%; (3) the stability of anthocyanin dyes is stable at acidic pH from pH 2 – pH 5, at a temperature of 80˚C and the effect of long exposure to the lamp makes the anthocyanin dyes unstable; and (4) dragon fruit syrup was stable at almost the same pH of dragon fruit syrup without coloring and added dragon fruit syrup, namely 3.42 and 3.89.

This community service aims to provide an understanding of simple bookkeeping for TAPE business actors in Pakem village, Pakem sub-district, Bondowoso district. Entrepreneurship is something that is very hotly discussed, starting from creating types of business such as permits from the relevant government to setting the concept which must be more measurable so that the business being developed becomes more useful and produces positive results. The method used is based on the criteria for achieving maximum understanding and outcomes regarding bookkeeping. so that business actors can do it well. Based on understanding through counseling activities and workshops regarding bookkeeping using the TAPEntar type, the pre-questionnaire results were 93.2% in the category of never having attended training, while the post-questionnaire results at the end could increase drastically to 98.2% who already understood bookkeeping using TAPEntar.

Developing the quality of educators in Islamic boarding schools plays a crucial role in realizing competitive Islamic boarding schools, adapting to current developments, and being open to renewal. This study aims to describe the planning, implementation, evaluation, and follow-up of collaborative development with educators to create competitive Islamic boarding schools. The study employed a qualitative approach with a multi-site case study design at Darunnajah Islamic Boarding School and Amanatullah Islamic Boarding School. Data were collected through observation, interviews, and documentation using purposive sampling techniques, and analyzed using triangulation. The research results show that, first, educator quality development planning tends to be conducted periodically, taking into account the complexity of the problems, the characteristics of human resources, and the needs of the development program. Second, the implementation pattern of educator quality development varies according to the governance and leadership style applied; the more participatory and adaptive the leadership, the greater the opportunity for integration between traditional values and modern management practices. Third, educator quality evaluation generally includes aspects of institutional performance, the effectiveness of the learning process, educator self-reflection, and analysis of the institutional context. Fourth, follow-up to mutual development requires the implementation of sustainable mutual management principles realized through training programs, a tiered evaluation system, and consistent stakeholder involvement. This finding confirms that systematic and contextual development of educator quality is an important factor in building the competitiveness of Islamic boarding schools in the modern era.
