Abstract

Kualitas  dan  harga  merupakan  dua  hal  yang  saling  berkaitan satu  sama  lain. Peningkatan kualitas  suatu produk akan menambah  biaya  yang  akan dibebankan  pada harga  jual  dari  produk  bersangkutan.  Hal  ini  menjadi  penting  untuk  merencanakan perbaikan  desain  produk  KAFO  (Knee  Ankle  Foot  Orthosis)  dalam  usaha  mencapai keberhasilan  produk  bagi  pengguna.  Kondisi  ini  juga  membawa  kepada  kreatifitas perancangan dan ketersediaan informasi mengenai tingkat utilitas konsumen dari produk yang digunakan. FAST  method  adalah  metodologi  yang  secara  lengkap  digunakan  untuk  mengidentifikasikan  yang  berkaitan  dengan  faktor-faktor yang mempengaruhi  biaya  maupun usaha  dalam  membangun  suatu  produk,  proses  ataupun  pelayanan  untuk  mencapai keseimbangan  fungsional  antara  biaya,  kehandalan  dan  performasi.  Keseimbangan fungsional  ini  dicapai  melalui  pembangkitan  alternatif  dari beberapa  ide.  Ide-ide  yang berpotensi  dalam  peningkatan  performansi  dievaluasi  melalui  Analisa  Hirarki  Proses dan ide-ide  yang tidak memenuhi persyaratan  perancangan  dikeluarkan  setelah melalui mekanisme team pakar dalam pemberi an nilai desain alternatif. Dalam pembahasan  ini terdapat lima tahap  kerja,  yang mana  implementasi  ke lima tahap kerja tersebut saling mendukung satu dengan lainnya secara sistematis. Lima tahap  kerja  tersebut  dikenal  dengan  rencana  kerja  lima  fase  yang  meliputi  tahap informasi,  tahap  kreatif,  tahap  analisa,  tahap  perkembangan,  dan  tahap  presentasi. Analisa hirarki proses berada pada tahap perkembangan produk, dan keseluruhan tahap ini  disebut  juga  sebagai  rekayasa  nilai,  team  yang  diikutsertakan  meliputi  beberapa disiplin ilmu yang sudah dikenal dalam menangani rekayasa produk KAFO Kata kunci: Rekayasa nilai, Metode FAST, Analisa Hirarki Proses.   Quality and price are two things that are related to each other. Improving the quality of a product will increase the costs to be charged on the selling price of the product concerned. It is important to plan the improvement of product design KAFO (Knee Ankle Foot Orthosis) in an effort to achieve success for new products to users. This condition also leads to creative design and availability of information regarding the level of consumer utility of the products used. FAST method is a complete methodology used to identify related factors that affect the cost and effort in building a product, process or service to achieve a functional balance between cost, reliability and performasi. Functional balance is achieved through the generation of several alternative ideas. The ideas that have the potential in improving performance is evaluated through analysis Hierarchy Process and ideas that do not meet the design requirements issued after a team of experts in the mechanism of giving an alternative design value. In this discussion there are five stages of labor, which is the implementation of the five stages of this work support each other systematically. Five stages of the work is known for its five-phase plan that includes the information stage, the creative stage, the analysis stage, developmental stage, and stage presentations.

Abstract

The pandemic has significantly impacted many shops closing and stopped production by artisans in the leather bag & shoe industry in Tanggulangin Sidoarjo. The development of e-commerce ecosystem studies shows that a deep understanding of the interactions between actors in this ecosystem can significantly improve online sales performance for SMEs. This study aims to identify the components and relationships between elements in the e-commerce ecosystem to support online sales in SMEs. This study uses the Delphi method with structured and in-depth interviews with several e-commerce SME experts. The components of the e-commerce ecosystem analyzed are marketing, platform, communication, payment, shipping & logistics, and productivity using descriptive analysis and framework visualization. The researchers proposed improving industry support components such as digital marketing training institutions, product photography and packaging design services, and product content creation services in the e-commerce ecosystem. This study is limited to the leather bag and shoe industry in Tanggulangin, Sidoarjo, which may restrict the generalizability of its findings to other sectors or regions. Additionally, the reliance on a small number of e-commerce experts and the lack of longitudinal testing for proposed solutions leave aspects like dynamic interrelationships and long-term sustainability underexplored.

Abstract

Background: Many MSMEs in Indonesia struggle to comply with the packaging label standards from the Indonesian Food and Drug Authority (BPOM). The root of this problem is knowledge gaps among MSME owners about labeling standards. Contribution:  This community services program contributes to enhance awareness of BPOM-compliant food packaging among MSMEs through counseling programs.  This program differs from previous counseling programs by incorporating digital aids, specifically in redesigning packaging that complies with BPOM standards. Method: Thirty participants attended an interactive discussion and counseling session in Purwodiningratan Village, Surakarta. Using visual aids and digital packaging design examples to show compliance, the session discussed BPOM's standards. Semi-structured interviews and post-session assessments were done to assess influence; descriptive analysis was then used for interpretation. Results:  Showed that 80% of the participants engaged actively in conversations, and 70% desired to implement what they learned in the counseling session. Conclusion: The counseling session increased participants' understanding of standard food packaging regulations and shifted their perceptions. Early signs of behavioral change supported the efficiency of participatory counseling in improving MSMEs' compliance with regulations.

Abstract

Rapid population growth has resulted in increased waste production, with projections that global waste will reach 3.4 billion tons by 2050, posing serious environmental challenges. Waste separation and recycling are essential strategies to address this issue, but community participation in waste segregation practices is still lacking. This study aims to identify and analyze the factors influencing household waste separation behavior through a systematic review conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A comprehensive literature search was conducted utilizing the Scopus database, yielding 19 relevant articles and two additional articles identified through a manual search on Google Scholar. The analysis revealed that most studies applied the Theory of Planned Behavior (TPB) to analyze the factors influencing waste separation intentions and actions. Commonly applied variables in research include attitudes, norms, awareness, knowledge, perceived behavioral control, law and regulation, and situational factors. The findings are expected to provide insights for researchers and support creating more effective policies to increase community involvement in sustainable waste management.

Abstract

Growing consumer interest in natural wellness products, particularly essential oils, highlights the need to understand key quality product attributes affecting consumer satisfaction. In the digital era, customer reviews in marketplaces have become the main source of consumer-driven insights for improving production and service processes. However, conventional approaches often fail to systematically extract actionable insights from these unstructured data sources. This study proposes an integrated machine learning framework for three market on essential oils and their derivatives. This framework transforms thousands of online customer reviews into a structured analysis of satisfaction dimensions. The approach uniquely contributes by employing regression model combined with Explainable AI (SHAP) and KANO Classification to systematically applied based on SHAP insights to develop a marketing strategy based on three market segments for essential oil products and their derivatives. Eleven critical satisfaction dimensions were extracted, including aroma, price, packaging, delivery, and others. These segment-specific insights imply that producers should prioritize reliable pricing and delivery for low-tier markets, ensure strict price fairness and value consistency for mid-tier consumers, and, for high-tier segments, focus on integrating diffuser compatibility as a basic requirement while leveraging bonuses as emotional value-adds to enhance customer delight. Theoretically, this research introduces a scalable, Explainable AI-based approach for applying the Kano model to unstructured textual data, overcoming limitations of traditional survey methods.  Despite its strengths, this study is limited by the absence of validation for the Kano categorization through survey-based procedures. Future work will address this limitation by conducting perception-based surveys or interviews to validate and refine the inferred categorizations. Nonetheless, this research contributes a methodology and provides actionable strategies for essential oil producers to align product improvements with consumer expectations in digital commerce environments.

Abstract

Higher education institutions often face a number of challenges in managing data and reporting information effectively, such as limited availability and distribution of information. This also happened in the Industrial Engineering Study Program at Sebelas Maret University (PSTI UNS). PSTI UNS needs a performance monitoring platform for study programs in the field of student and graduate affairs to support study program management and quality assurance activities. The information system currently provided by UNS is not yet able to complete PSTI's needs for monitoring and quality assurance functions at the study program level. A solution that has been proven to be able to solve similar problems is through the use of an information dashboard or dashboard. The unavailability of dashboards and PSTI's urgent need for study program performance monitoring activities led this research to design a dashboard in accordance with PSTI's needs and ensure that the design developed could be used immediately. To ensure the success of the design, this research uses a user-centric method in the design process and heuristic usability testing as an evaluation stage. This research produced a dashboard design, data filling template, and a guidebook that was used to make dashboard use easier. The successfully designed dashboard has more complete study program level information from the information system provided by UNS and has succeeded in meeting the needs of PSTI users with a user satisfaction level of 7.6. Based on the level of implementation readiness, this dashboard scored 86.83% for its usability test with minor problems. The root of the problem identified has been found and repaired.
