Shrimp shell waste is a potential marine biomass resource rich in bioactive compounds such as astaxanthin and chitin, yet remains underutilized in the livestock sector. This study aimed to evaluate the effect of incorporating shrimp shell meal into duck (Anas sp.) feed rations on the yolk color intensity of duck eggs. The experimental design applied a completely randomized design (CRD) with a single factor and four treatments: D0 (100% rice bran, control), A1 (rice bran + 2% shrimp shell meal), A2 (rice bran + 6%), and A3 (rice bran + 10%), with a 21-day observation period. The primary parameter measured was yolk color intensity, assessed visually using a standardized color scale. The results indicated that the addition of shrimp shell meal significantly enhanced yolk color intensity, with the highest pigmentation observed in the A3 treatment. Astaxanthin, functioning as a natural carotenoid pigment, was biologically absorbed and distributed into the yolk via lipophilic pathways, while chitin supported gut health and nutrient absorption efficiency. This study aligns with the principles of the circular economy by valorizing marine processing waste as a functional feed ingredient. A 10% inclusion rate was found to be visually optimal; however, further studies are required to assess its physiological impacts and economic feasibility in broader production contexts.

CV. Rasyid is a business unit specializing in the production of ecoprints. Currently, one of the most sought-after clothing colors by consumers is burnt coral red. However, CV. Rasyid has been unable to meet this demand due to challenges in the production process, specifically the deterioration of the color during the fixation stage. To address this issue, the community service team from the Industrial Engineering Study Program at Muhammadiyah University of Gombong (Unimugo) provided facilitation and support. The program aims to equip participants with the knowledge and skills needed to produce burnt coral red for ecoprints using secang dye. The activities include preparation, implementation, monitoring, and evaluation. The implementation process was conducted with guidance on color extraction, mordanting, design printing, and fixation. Monitoring results indicate that CV. Rasyid successfully carried out the burnt coral red ecoprint production process independently without significant issues. While the colors produced may vary slightly, this is not a concern, as such variations are a unique characteristic of ecoprint products.

Reading the Al-Qur'an is one of the religious practices which is a good practice with the hope of being able to read the Al-Qur'an accurately, with tartil, and with good pronunciation. To form an Islamic character by being able to create the character of the Qur'an, it is also important to get used to reading the Qur'an. The method in this service is a persuasive method for recitation participants, then the children are given material about planting Islamic characters, so that children can learn to read the Koran. Providing guidance to children in the process of this activity is carried out by providing Islamic character material to children, as well as teaching reading the Qur'an, so that children in Lakambau Village can maximize their academic work activities at the University of Muhammadiyah Buton. The results of the participants' posttest showed that participants reached the high category of 10 people or 66.67%, the medium category was 4 people or 26.66%, while the low category was 1 person or 6.67%. The conclusion in this service is that children are very enthusiastic about participating in the Al-Qur'an learning activity program, so that students can instill Islamic character in children in Lakambau Village, South Buton Regency.
