Abstract

The unemployment rate in Indonesia is quite high, where the average value in Indonesia is 18%, the largest among Cambodia, Nigeria, and lower-middle-class countries, which show an average of 12%. The high unemployment rate is caused by the level of motivation of students to continue working, studying or participating in competency training with a lack of interest. To increase students' interest, it is necessary to have a large number of critical communications to arouse students' enthusiasm and motivation. The method used is qualitative and quantitative where to design the system design and system validation, the technique used is the System Development Life Cycle Waterfall. The results obtained by the Heuristic Evaluation stated that not many things needed to be improved for the system that was created and the SUS (System Usability Score) stated that it was good with a minimum score of 68 given by 5 experts. The Blockchain system can already be run or applied to the wider community. Keywords: Blockchain, Heuristic Evaluation, System Usability Scale, Siswa, System Development Cycle

Abstract

The increase in consumption of bottled drinking water (AMDK) reached 54.11% from 2018 to 2020, which has a negative impact on the environment. SiHatin Waste Bank is a community formed to manage the waste. Waste Bank officers face the risk of injury and infection, especially to the hands, due to the lack of Personal Protective Equipment (PPE) during the processing of plastic glass AMDK waste. This condition creates new problems for Waste Bank officers, the purpose of this activity is to implement education on the use of finger protection in sorting and cutting plastic glass AMDK. The method of implementation of the activity involves observation, preparation of educational materials, direct training at the Waste Bank location, and evaluation of the impact through monitoring changes in officer behavior. The implementation of education on the use of PPE succeeded in increasing staff understanding by 41%, which is expected to reduce the incidence of injury and infection in the process of cutting plastic bottled water. It also contributed positively to the overall operations of the Waste Bank. In the next stage, there is a need for comprehensive monitoring by involving stakeholders to support the implementation of education holistically in an effort to manage sustainable waste.

Abstract

Food Additives (BTP) in current consumer products increase the risk of non-communicable diseases such as diabetes, kidney failure, and cancer, particularly in children. Housewives play a central role in managing family consumption to minimize these risks. This community service activity aims to enhance the knowledge and awareness of 'Aisyiyah women in Buluspesantren, Kebumen Regency, regarding food safety and BTP regulations. The implementation method included preparing materials based on BPOM regulations, interactive education, product discussions, and simulations on reading nutrition labels. The results showed high enthusiasm from participants who are now more critical in distinguishing between natural and synthetic additives. Participants reported a significant improvement in their ability to identify food ingredients and additives in everyday products. The final evaluation recorded a 22.2-point increase in participant understanding. By establishing the habit of reading food labels, it is expected that the risk of non-communicable diseases within the family environment can be reduced, thus improving public health literacy and dietary choices within the community.

Abstract

This study addresses the need for affordable visual inspection support in micro, small, and medium enterprises (MSMEs) engaged in screen-printing production. Although machine vision and deep learning have been widely applied in manufacturing quality control, many existing systems are designed for relatively controlled industrial settings and require stable cameras, lighting, computing resources, and technical expertise. This condition limits direct adoption by small MSMEs, where image acquisition is often performed with operator-level devices under variable lighting and background conditions. This study designed and evaluated an initial low-resource visual inspection pipeline consisting of low-cost image acquisition, five-class defect labeling, MobileNetV3-based transfer learning, performance evaluation, and TensorFlow Lite conversion. The dataset consisted of 160 screen-printing images grouped into five classes: good, misalignment, bleeding, pinholes, and ghosting. The preliminary evaluation yielded 24.38% multiclass accuracy and a loss of 2.5635, indicating that the model could not yet reliably distinguish detailed defect categories. The converted TensorFlow Lite model was 5.43 MB, indicating that the technical conversion path was feasible. A binary quality-control interpretation produced 75.63% accuracy, but 27 defective images were still predicted as pass QC. Therefore, the pipeline cannot be treated as a final quality-control decision system. The main contribution of this study is empirical evidence that image-acquisition quality, dataset sufficiency, class separability, and training configuration are critical bottlenecks in developing lightweight deep-learning-based inspection for low-resource MSME environments.

Abstract

This study examined whether wall color conditions were associated with differences in repetitive assembly performance during a controlled simulated task. A quasi-experimental between-subjects design was applied involving 116 student participants aged 18–22 years. Participants were allocated through stratified randomization based on age and sex into four identical rooms with matte-painted red, white, blue, or green walls, with 29 participants in each condition, consisting of 15 male and 14 female participants. Environmental and procedural factors, including lighting at 550 lux, temperature at 24 °C, ambient noise at 75 dBA, equipment, instructions, task model, and 30-minute session duration, were standardized. All groups were tested concurrently to minimize temporal variation. After an initial practice opportunity, participants completed the same 10-component toy truck assembly task. Performance was assessed using completion time, accuracy, and productivity. Because the data did not fully satisfy parametric assumptions, Kruskal-Wallis tests were used, followed by Holm-adjusted Mann-Whitney comparisons. The results showed significant differences across wall color conditions for completion time, accuracy, and productivity. Green produced the strongest observed performance profile, with a mean completion time of 3.38 minutes, accuracy of 92.24%, and productivity of 6.30 correct assemblies per minute, followed by blue. These findings suggest that wall color may function as a supplementary environmental ergonomics factor in repetitive manual assembly settings. However, the results should be interpreted as evidence for controlled pilot evaluation rather than as a definitive industrial color standard. Keywords: Workspace Color; Environmental Ergonomics; Repetitive Assembly; Productivity; Accuracy

Abstract

Penelitian ini bertujuan untuk menganalisis kondisi ergonomi lingkungan kerja pada UMKM Tonight Sablon dengan fokus pada tiga parameter utama, yaitu suhu, tingkat kebisingan, dan intensitas pencahayaan. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan teknik observasi langsung dan pengukuran empiris menggunakan alat termometer digital, pengukur tingkat suara, dan lux meter. Hasil pengukuran menunjukkan bahwa suhu dan kelembaban pada beberapa ruang produksi berada di luar ambang batas yang direkomendasikan yaitu suhu diatas 28 derajat celcius dan kelembaban diatas 60%, yang berpotensi menyebabkan ketidaknyamanan dan stres panas pada pekerja. Tingkat kebisingan di ruang sablon melebihi nilai ambang batas 85 dB, sehingga berisiko terhadap kesehatan pendengaran dan menurunkan produktivitas. Selain itu, pencahayaan di seluruh area kerja juga tidak memenuhi standar minimum 500 lux untuk pekerjaan agak halus, yang dapat mempengaruhi ketelitian kerja dan kesehatan mata. Temuan ini menegaskan pentingnya penerapan prinsip ergonomi dan K3 dalam menciptakan lingkungan kerja yang aman, nyaman, dan produktif. Rekomendasi perbaikan meliputi peningkatan sistem ventilasi, penggunaan alat pelindung diri, serta optimalisasi pencahayaan buatan.
