Abstract

PT. MRP merupakan perusahaan yang bergerak dibidang produksi manufaktur seperti : Dies Product, Mold Product, Checking Fixture, Machine Product, dan standar part product, tetapi produk – produk komersil tersebut bersifat job order. Berdasarkan hasil pengamatan yang di lakukan pada perusahaan tersebut didapatkan tidak tercapainya target delivery per bulan yang dimana perusahaan mempunyai target sebesar 80 %. Aktualnya dalam waktu 6 bulan target rata - rata pengiriman hanya sampai 70 %. Dengan ini mengakibatkan beberapa pengiriman produk menjadi terlambat tidak sesuai dengan jadwal dan membuat pelanggan jadi mulai kehilangan kepercayaan serta bisa membuat pemasukan perusahaan menjadi menurun di kemudian hari. Maka dari itu perlu dilakukan analisis menggunakan metode Failure Mode and Effect Analysis,Failure Mode and Effect digunakan untuk mengindetifikasi bagaimana suatu proses pengiriman mengalami keterlambatan, tidak tercapainya target delivery sehingga menyebabkan terlambatnya barang sampai ke konsumen atau subcont. Setelah dilakukan identifikasi dengan metode Failure Mode and Effect Analysis nantinya akan menghasilkan Nilai Risk Priority Number. melakukan perhitungan RPN untuk mengetahui dan menentukan angka prioritas risiko yang didapatkan dari perkalian Severty, Occurance, Detection dari beberapa penyebab, sehingga ditemukan 3 nilai RPN tertinggi yaitu kurangnya SDM dengan nilai RPN 392, sering terjadinya repair barang setelah selesai produksi dengan nilai RPN 210, dan kurang control setiap operator dengan nilai RPN 175.Kata Kunci : Failure Mode and Effect Analysis,Failure Mode and Effect (FMEA), Keterlambatan Delivery Ontime, Risk Priority Number (RPN)

Abstract

Introduction: The rapid growth of household waste in urban areas poses a serious challenge to environmental health. The integration of the IoT into waste management is considered an innovative solution, offering real-time monitoring, collection efficiency, and greater system transparency. This study aims to examine the influence of perception, attitude, awareness, and practices on environmental health impacts in the context of IoT adoption. Methods: A cross-sectional survey was conducted with 120 households in the Greater Jakarta area, and the data were analyzed using SEM-PLS. Results: The results reveal that perception significantly influences attitude (p < 0.001), and attitude significantly influences awareness (p < 0.001). The structural model demonstrates strong predictive power with R² values of 0.566 for attitude, 0.552 for awareness, and 0.839 for environmental health impacts. Standardized path coefficients show significant effects for perception ? attitude (? = 0.752; p < 0.001), attitude ? awareness (? = 0.743; p < 0.001), and practices ? environmental health impact (? = 0.864; p < 0.001). Model diagnostics confirm reliability and validity, including AVE > 0.50, CR > 0.70, HTMT < 0.85, and VIF < 3. However, awareness does not directly affect environmental health (p > 0.05), indicating the presence of an intention–behavior gap. In contrast, actual waste management practices emerged as the most dominant predictor, with the largest effect on environmental health outcomes (p < 0.001). Conclusion: These findings highlight the necessity of policy strategies that go beyond raising awareness and digital literacy, ensuring the transformation of awareness into consistent practices through adequate infrastructure, incentive systems, and regulatory enforcement. This study contributes to strengthening the concept of smart cities and supports sustainable development strategies in urban settings.

Abstract

Introduction: Urban waste growth in metropolitan areas intensifies sanitation challenges and environmental health risks. Smart waste management offers data-driven waste services; however, its effectiveness depends on public acceptance. Despite increasing implementation of smart waste technologies, limited empirical evidence explains how behavioral and psychosocial determinants shape citizen acceptance in developing urban contexts, particularly in relation to perceived environmental health conditions rather than objectively measured environmental outcomes. This study investigates the determinants of smart waste management acceptance and its association with perceived urban environmental health in Jabodeta, Indonesia, using an extended Technology Acceptance Model that integrates digital literacy, environmental concerns, social norms, and perceived risk Methods: A cross-sectional survey of 120 respondents was conducted and analyzed using partial least squares structural equation modeling with bootstrapping. Measurement quality met recommended thresholds, including outer loadings greater than 0.70, average variance extracted ranging from 0.52 to 0.78, strong reliability, and HTMT values below 0.90. Results: The structural model explained substantial variance in perceived ease of use (R² = 0.81) and perceived usefulness (R² = 0.69), moderate-to-strong variance in acceptance (R² = 0.62), and modest variance in perceived urban environmental health (R² = 0.18). Digital literacy positively predicted perceived ease of use (? = 0.52), while perceived risk negatively predicted perceived ease of use (? = ?0.37). Perceived ease of use strongly predicted perceived usefulness (? = 0.74). Environmental concern (? = 0.26) and social norms (? = 0.15) positively predicted perceived usefulness. Perceived usefulness (? = 0.32) and perceived ease of use (? = 0.19) positively predicted acceptance, and acceptance was positively associated with perceived urban environmental health (? = 0.43). Mediation analysis identified statistically significant indirect effects for selected pathways; however, these effects should be interpreted cautiously due to inconsistencies in directional patterns. Conclusion: The findings suggest that perceived environmental health benefits associated with smart waste management are linked to sustained public acceptance. This acceptance is supported by digital literacy, socially reinforced perceptions of usefulness, and effective risk communication combined with reliable service delivery. These results highlight the importance of behavioral and perceptual factors in shaping citizen engagement with smart environmental technologies, while acknowledging that the study reflects perceived rather than objectively measured environmental outcomes.

Abstract

Krisis lingkungan akibat dominasi limbah plastik dalam sektor pangan mendorong urgensi pembaruan desain kemasan produk yang ramah lingkungan namun tetap memenuhi ekspektasi kenyamanan konsumen. Penelitian ini bertujuan untuk mengembangkan strategi dan prototipe desain kemasan makanan inovatif yang mengintegrasikan pendekatan Ergonomic Function Development (EFD) dengan prinsip keberlanjutan secara menyeluruh guna mendukung pencapaian Sustainable Development Goals (SDGs). Riset terapan ini menggunakan pendekatan metode kombinasi (mixed method). Data primer dihimpun dari minimal 30 responden konsumen melalui observasi interaksi fisik, kuesioner Voice of Customer (VoC), serta Focus Group Discussion (FGD) bersama pelaku usaha, yang selanjutnya dianalisis secara terstruktur menggunakan matriks House of Ergonomics (HoE). Hasil penelitian menunjukkan bahwa parameter prioritas konsumen bertumpu pada kemasan biodegradabel bebas kontaminasi kimia, fungsionalitas fitur fisik berupa pegangan (handle), sistem penutup tahan lama, serta stabilitas penjagaan suhu makanan. Karakteristik teknis tersebut diwujudkan ke dalam pengembangan dua model prototipe kemasan berbahan sirkular ampas tebu dan kulit jagung, yakni Model Artistik Natural untuk segmentasi pasar lokal/organik, serta Model Modern Fungsional dengan handle terintegrasi yang dioptimalkan untuk kebutuhan logistik ritel skala besar. Integrasi model desain ini terbukti berkontribusi nyata pada pemenuhan target SDG 3, SDG 9, SDG 12, dan SDG 14. Meskipun implementasi pada skala UMKM masih menghadapi tantangan biaya dan investasi teknologi awal, strategi digitalisasi desain dapat menjadi solusi akselerasi pengembangan kemasan makanan masa depan yang human-centered dan eco-efficient.

Abstract

Maternal mental health education and depression screening had not been integrated into the routine antenatal classes conducted at Posyandu Seroja, within the service area of UPTD Parigi Public Health Center, South Tangerang City, limiting the early identification of psychological problems among pregnant women. This community service program aimed to improve maternal mental health literacy by integrating mental health education and depression screening into antenatal classes. The program involved 19 pregnant women and employed a participatory educational approach consisting of program socialization, pre-test, depression risk screening using the Edinburgh Postnatal Depression Scale (EPDS), interactive lectures, group discussions, and post-test. Participants' knowledge and attitudes were assessed using validated and reliable questionnaires, while the screening results were analyzed descriptively. The findings showed an increase in the mean knowledge score from 6.95 to 7.42 and the mean attitude score from 21.21 to 21.95 following the educational intervention. In addition, four of the 19 participants (21.1%) were identified as being at risk of depression and were referred for further follow-up according to the existing health service procedures. The program improved participants' understanding of maternal mental health while providing preliminary information to support early detection of psychological problems in primary healthcare settings. Integrating mental health education and depression screening into antenatal classes is a feasible community-based approach to strengthening maternal mental health promotion, prevention, and early detection within primary healthcare services.

Abstract

The external audit findings of the Quality Control Laboratory indicate that the chemistry and microbiology laboratories share the same operational area, causing overlapping flows of activities, personnel, and materials and increasing the risk of cross-contamination. This study aims to develop an improved laboratory layout in accordance with ISO/IEC 17025:2017, evaluate its operational performance using ProModel, and assess time efficiency and potential labor cost savings. CORELAP was used to generate an initial layout based on activity proximity, while CRAFT was applied to refine the layout based on movement frequency and inter-area distances. The proposed layouts included a new microbiology laboratory and a redesigned chemistry laboratory. The Total Load Distance of the chemistry laboratory decreased from 371.50 to 341.50, representing an 8.08% reduction, while the microbiology laboratory decreased from 617 to 389, representing a 36.95% reduction. Simulation results showed that the proposed layout reduced the Average Time in System for 6 of 7 sample types, with the highest efficiency reaching 68.07%. The reduced processing time also indicated potential labor cost savings, based on the actual sample volume and the labor cost per minute. Therefore, the CRAFT-generated layout provides an alternative to improve contamination control, process efficiency, and laboratory operating costs.
