Abstract

Penelitian ini bertujuan untuk mengidentifikasi, menganalisis, dan merumuskan strategi mitigasi risiko operasional pada proyek konstruksi jalan di fasilitas pengolahan gas alam darat dengan memperhatikan prinsip keberlanjutan dan ramah lingkungan. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan studi kasus. Data dikumpulkan melalui observasi lapangan, wawancara, kuesioner, dan studi dokumentasi. Analisis risiko dilakukan menggunakan metode Failure Mode and Effect Analysis (FMEA) untuk mengidentifikasi dan memprioritaskan 15 potensi risiko berdasarkan nilai Risk Priority Number (RPN). Hasil analisis menunjukkan bahwa tiga risiko dengan prioritas tertinggi adalah cuaca ekstrem (RPN = 422), kecelakaan kerja berat (RPN = 404), dan dampak lingkungan (RPN = 353). Strategi mitigasi selanjutnya dirumuskan menggunakan metode House of Risk fase 2 (HOR 2) untuk mengevaluasi efektivitas dan tingkat kesulitan implementasi dari enam tindakan pencegahan yang diusulkan. Berdasarkan hasil perhitungan Effectiveness to Difficulty (ETD), strategi Pelatihan, Pemantauan, dan Kepatuhan Berkelanjutan menjadi prioritas utama karena mampu mengurangi berbagai sumber risiko secara simultan sekaligus memperkuat budaya kerja berkelanjutan (sustainable work culture). Hasil penelitian ini memberikan kerangka kerja yang sistematis untuk pengelolaan risiko operasional pada proyek infrastruktur jalan di sektor minyak dan gas bumi, sehingga dapat mendukung pelaksanaan proyek yang lebih aman, efektif, produktif, dan selaras dengan prinsip pembangunan berkelanjutan.

Abstract

This study aims to determine the priority of chicken raw material quality risks and formulate technical responses to support supply chain risk mitigation in restaurant operations. The research object was Restoran XYZ, Surabaya, which relies on chicken as its main raw material. This study used an integrated Analytic Hierarchy Process (AHP) and Quality Function Deployment (QFD) approach. Primary data were collected through observation, interviews, and questionnaires involving restaurant stakeholders responsible for procurement, inspection, and processing of chicken raw materials. AHP was used to determine supply chain risk priorities, while QFD was used to translate quality attributes into technical responses through the House of Quality matrix. The AHP results show that the highest priority risk was chicken quality not meeting standards, with a weight of 0.422, followed by delayed delivery at 0.254, price mismatch at 0.162, inaccurate weighing at 0.104, and quantity mismatch at 0.059. The inconsistency ratio was 0.09, indicating acceptable pairwise comparisons. The QFD results show that the main quality attributes were chicken freshness, followed by feather cleanliness, cutting condition, and chicken weight. The main technical responses were worker training at 26.87%, rechecking weighing results at 22.39%, preparing delivery invoices at 22.39%, careful weighing at 17.91%, and scheduling raw material delivery at 10.45%. These findings show that integrating AHP and QFD can support structured decision-making by linking risk priorities with operational quality improvement. The results can be used to develop standard operating procedures for raw material acceptance, supplier evaluation, and supply chain risk mitigation.

Abstract

Proses pemotongan panel kayu secara manual pada simulasi lini perakitan menunjukkan waktu siklus yang tinggi dan tidak stabil sehingga stasiun cutting menjadi pembatas aliran produksi. Penelitian ini mengevaluasi pengaruh jig sederhana terhadap perbaikan metode kerja melalui pengurangan aktivitas tidak bernilai tambah dan penstabilan posisi material sebelum pemotongan. Data dikumpulkan melalui studi waktu menggunakan stopwatch, masing-masing lima pengamatan pada kondisi tanpa jig dan lima pengamatan menggunakan jig. Analisis mencakup waktu normal, waktu standar, output standar, peta proses operasi, peta aliran proses, dan pengujian statistik. Hasil menunjukkan waktu standar turun dari 55,37 detik menjadi 34,74 detik, sedangkan output standar meningkat dari 65,02 menjadi 103,63 unit/jam. Simpangan baku sampel turun dari 1,03 detik menjadi 0,11 detik, dan empat aktivitas tidak bernilai tambah yang menjadi target perbaikan berhasil dihilangkan. Uji Welch menunjukkan perbedaan signifikan antara kedua kondisi (t = 37,74; df = 4,10; p < 0,01). Temuan ini menegaskan bahwa penggunaan jig efektif mengurangi bottleneck yang diamati dan meningkatkan kestabilan proses pada simulasi laboratorium.  Keywords: Assembly Line, Bottleneck Elimination, Jig Design, Work Measurement, Work Method Improvement

Abstract

Kegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh kebutuhan pelaku usaha mikro, kecil, dan menengah (UMKM) untuk memahami kesiapan dokumen sebelum mengajukan sertifikasi halal. Banyak pelaku usaha telah menjalankan produksi pangan secara rutin, tetapi belum seluruhnya menyusun dokumen dasar seperti Nomor Induk Berusaha (NIB), data produk, daftar bahan baku, label, dan alur produksi tertulis. Kegiatan dilakukan di Kelurahan Keputih, Kecamatan Sukolilo, Kota Surabaya pada 26 November 2025 dengan melibatkan 34 peserta, terdiri atas 24 pelaku UMKM dan 10 warga yang sedang merintis usaha. Metode kegiatan meliputi sosialisasi, inventarisasi dokumen, pemetaan alur proses, diskusi kendala, dan penyusunan rekomendasi pendampingan. Hasil pemetaan menunjukkan bahwa 9 pelaku UMKM atau 37,5% telah memiliki NIB, sedangkan 15 pelaku UMKM atau 62,5% belum memilikinya. Sebanyak 18 pelaku UMKM atau 75,0% mampu menjelaskan alur produksi secara lisan, tetapi hanya 6 pelaku UMKM atau 25,0% yang telah menuliskannya. Kegiatan ini menunjukkan bahwa persoalan utama peserta bukan hanya kurangnya informasi, tetapi juga belum tersusunnya dokumen kerja yang diperlukan untuk sertifikasi halal. Pemetaan berbasis alur proses membantu peserta melihat urutan dokumen yang harus disiapkan dan menjadi dasar pendampingan lanjutan secara lebih terarah.

Abstract

The modern era has made freelance workers a trend, freelance employees work individually from their workplace. Freelance employees provide the freedom to choose the work they want without being tied to a contract, but in practice, freelance workers are very unfulfilled, such as in the health sector and field facilities. PT. X, which is a well-known provider company in Indonesia, has problems with employees who often experience complaints such as body aches, sprains and minor injuries after work. Improving work posture is very necessary to help freelance employees feel comfortable working, so it is necessary to analyze work posture using the Rapid Upper Limb Assessment (RULA) method. The research results show that action level 4 is obtained which requires the company to immediately carry out inspections and changes (right now). The proposed improvement in this research is that there is a need to improve work methods or systems (SOP) when carrying out the cable planting fireplace process and provide complete work facilities.

Abstract

Value Engineering (VE) has evolved from a cost-control technique into a Value Management approach integrating function, life-cycle cost, quality, sustainability, digitalization, and organizational capability. This study maps the themes, methods, and contributions of VE across engineering systems through a systematic literature review. The search generated 1,000 initial records. After deduplication, multistage screening, DOI and full-text verification, quality appraisal, and replacement of ineligible studies, a final corpus of 80 articles published in 2020–2026 was established. The articles were coded into seven themes, 21 subthemes, nine primary methods, ten integrative techniques, and ten contribution categories. Construction and infrastructure formed the largest theme (26.25%), while technical-economic case studies were the dominant method (31.25%). The most frequently reported contributions were cost efficiency (82.50%), decision quality (68.75%), and technical function or performance (55.00%). The review also identifies the growth of sustainability, BIM, automation, multi-criteria decision methods, and life-cycle costing. Major gaps concern inconsistent value metrics, the dominance of single-case studies, limited post-implementation evaluation, and uneven evidence across engineering systems. The study’s novelty lies in a quality-informed theme, method, and contribution evidence map.

Abstract

The increasingly competitive footwear MSME business environment requires business owners to improve service quality while maintaining customer satisfaction and loyalty. However, many MSMEs still face challenges related to response speed, service consistency, and personal communication. This study aims to analyze the service quality of footwear MSMEs in Bungah District using the SERVQUAL, Value Engineering, and TOPSIS approaches to determine priority strategies for service improvement. The study employed a quantitative method involving 70 customers of footwear MSMEs. The results showed that the average SERVQUAL gap was −0.75, indicating that service quality had not yet met customer expectations. The responsiveness dimension became the most critical aspect with a gap value of −1.25, followed by empathy at −1.00, while reliability had a gap of −0.60. These findings indicate that customers highly demand fast, responsive, and personalized services. Based on value engineering analysis, the service functions that contributed most significantly to quality improvement were rapid response, service accuracy, and customer communication. Furthermore, the TOPSIS method identified WhatsApp Business implementation as the top priority strategy for improving response speed, with a preference value of 0.78, followed by production and delivery scheduling with a value of 0.72. This study contributes to the development of MSME service quality improvement strategies that are more systematic, measurable, and customer-oriented.

Abstract

PT. AFS is a Limited Liability Company engaged in catering services. One of the most important divisions in this field is in the warehousing department. Receiving is the place where the goods are entered, while the store is the place where the goods are stored for a period of time with reference to the expiration date of the product. Goods collection is done when receiving incoming goods, moving goods from the receptionist to the store, and when requesting goods from the production room. Body posture is a determining factor in analyzing the effectiveness of a warehouse operator's work. If the operator's work attitude is wrong or not ergonomic, the employee will tire easily and bone abnormalities can occur. Complaints of Musculoskeletal Disorders are complaints of skeletal muscles that are felt by a person from very mild to severe complaints. For the RULA and OWAS methods, posture analysis is only carried out in the main warehouse. The final Rapid Upper Body Limb Assessment (RULA) score for both workers was Score 7 (Action Level 4) which indicates that this condition is dangerous and requires immediate inspection and changes (on the spot). And the Ovako Work Posture Analysis System (OWAS) shows category 4 (This attitude is very dangerous for the musculoskeletal system. Needs to be corrected immediately/currently) and Category 1 (in this system problems in the musculoskeletal system don't need to be fixed).PT.

Abstract

Digital work-system transformation intensifies human-technology interaction and creates a need to understand how cognitive ergonomics is applied, measured, and associated with human and system outcomes. This study maps cognitive ergonomics applications, mental-workload measurement approaches, and their relationships with performance, safety, usability, technology acceptance, and worker well-being. A systematic literature review was conducted on 52 full-text journal articles published from 2020 to 2026. Articles were selected through deduplication, multistage screening, DOI verification, quality appraisal, and extraction of 29 variables. The findings identify five application mechanisms: task and interface redesign, human-technology function allocation, cognitive-state monitoring, decision support and training, and integration into work systems. Measurement approaches include subjective ratings, performance measures, behavioral indicators, physiological and neurophysiological signals, task analysis, and multimodal assessment. Associations with outcomes are conditional because they vary according to task complexity, experience, age, duration, technology transparency, and environmental conditions. The review proposes a three-layer application-measurement-outcome framework in which workload functions as a linking mechanism and a source of feedback for redesign. The findings support multi-indicator evaluation, field validation, and designs that preserve cognitive fit, predictability, control, situation awareness, and recovery.
