Abstract

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.

Abstract

Limbah dari bengkel mobil berpotensi mencemari lingkungan jika tidak dikelola dengan baik. Bengkel Mobil Pantas belum menerapkan praktik manajemen pengelolaan limbah dengan tepat. Oleh karena itu, sosialisasi ini bertujuan untuk meningkatkan pemahaman dan wawasan pihak bengkel mobil mengenai pentingnya pengelolaan limbah dengan tepat. Kegiatan ini diawali dengan survei pendahuluan untuk mengetahui permasalahan di lapangan. Selanjutnya, dilakukan perumusan solusi dan implementasi yaitu berupa sosialisasi praktik terbaik manajemen pengelolaan limbah bengkel mobil, jenis-jenis limbah yang dihasilkan, cara pemilahan limbah, serta potensi pemanfaatan kembali limbah. Sosialisasi ini menyasar langsung kepada pengusaha bengkel mobil, baik pemilik maupun pekerja. Hasil survei pendahuluan menunjukkan bahwa pihak bengkel masih kurang memahami manajemen pengelolaan limbah. Setelah mengikuti sosialisasi, pengusaha bengkel menunjukkan antusiasme dan komitmen untuk menerapkan praktik pengelolaan limbah yang baik di bisnisnya. Kegiatan ini diharapkan dapat menjadi langkah awal dalam menciptakan lingkungan yang lebih bersih dan sehat.

Abstract

Stunting remains a serious health challenge in Indonesia. This study analyzes the role of Posyandu in reducing stunting in Sidomulyo Village, Cepiring Sub-district, Kendal District. Using analytical descriptive methods, this study evaluates program implementation, challenges and outcomes. Posyandu plays an important role in child growth monitoring, nutrition counseling, supplementation, mother-child health services, early intervention, and increasing community awareness. Collaboration with various parties, including KKN-T students, strengthens these efforts. Although comprehensive, there is still room for improvement, especially in integrating technology. This holistic and collaborative approach is in line with the Indonesian government's target of reducing the stunting rate to 14%.

Abstract

Students who are working on their thesis often experience stress due to demands to immediately complete their studies. This makes students feel easily anxious and afraid. One way students deal with stress is by writing about how they feel. This can be referred to as expressive writing. This study aims to determine the effectiveness of expressive writing on reducing academic stress levels for students of the Faculty of Psychology UNM. 13 participants were divided into the experimental group and the control group. This research uses quantitative methods with an experimental approach in the form of Pretest-posttest Control Group Design. This study showed a decrease in the mean academic stress score of the experimental group, from 63,3 to 47,3 and an increase in the mean academic stress score of the control group, from 55,3 to 57,8. The results of hypothesis testing also show that expressive writing is effective in reducing students' academic stress levels (t = 0.500, p = 0.004 < 0.05). Expressive writing which is done by writing topics related to emotional problems and trauma is proven to be able to reduce student academic stress. The result of this research can be a consideration for education provides to apply expressive writing for students who are working on their theses.

Abstract

The increase in consumption of plastic bottled drinking water (AMDK) has led to an increase in the amount of plastic waste that requires special handling. One of the main challenges in managing this waste is the process of cutting plastic cup rings, which has been done manually using a cutter or small knife. This manual method is not only less effective but also increases the risk of injury for waste pickers. This research aims to develop a safer and more effective plastic cup ring cutter. Through a socialisation programme and implementation of the tool at Bank Sampah SiHatin, the effectiveness of the tool was tested by comparing the manual method and the use of the cutting tool. The results of the analysis show that the use of this tool is able to increase the cutting speed by 58%, produce more uniform cuts, and eliminate the risk of injury due to the use of cutters. In addition, this tool also improves occupational safety and health (K3) aspects and has a positive impact on the economic value of cutting products. Thus, this innovation is an effective solution in plastic waste management in the informal sector and can be adopted more widely in various other Waste Banks

Abstract

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.

Abstract

Shrimp shell waste is a chitin-rich biopolymer with high potential for microbial bioconversion into value-added products. This study aimed to analyze the microstructural degradation of shrimp shells by the actinomycete isolate 18D38A1 under solid-state fermentation, using Scanning Electron Microscopy (SEM). A fresh sample preparation method was applied, involving washing and immersion in 70% ethanol, followed by vacuum drying and gold sputter-coating. Fermentation was conducted over a period of 1 to 4 days. SEM analysis revealed progressive structural deterioration of the shrimp shell matrix, including increased surface erosion, pore formation, and breakdown of chitin fibers, which became more pronounced each day. These observations indicate active and time-dependent biodegradation by isolate 18D38A1. The sample preparation protocol proved effective in preserving morphological features and enhancing SEM image clarity, enabling precise visualization of degradation stages. The combination of solid-state fermentation and optimized SEM preparation provides a reliable approach to evaluate the biodegradation process of chitinous waste by actinomycetes over time. This study demonstrates a practical SEM sample preparation method for visualizing the progressive biodegradation of shrimp shell by actinomycete isolate 18D38A1 from day 1 to day 4.
