In this research, the concept of designing a tool for automatically pulling cassava using the Quality Function Deployment (QFD) method is intended to design a cassava pulling tool by considering the needs and customer wants of cassava farmers as tool users. The aim of the research is to redesign the initial concept which is a continuation of previous research that carried out, because design activities or product design are important and absolute things to do before the production process and with QFD can be designed and developed the new products that are able to integrate quality into designs that meet consumer wants and needs which are translated into technical requirements. Based on the results of data processing and analysis, it is known that consumers wants for cassava pulling tools can be described in the customer requirements attribute, where the cassava pulling tool is made of light material, affordable price, can remove more than one stem, the tool is durable, safe to use and has additional functions besides pulling. And the technical characteristics (technical requirements) that influence the tool making process are the capability and strength of the driving machine, the quality of the driving machine, the quality of the light and non-corrosive frame, components for the driving system, the right finishing process. The conclusion from the HOQ analysis shows the greatest weight of importance with a value of 30% where the tool made can remove more than one cassava stem at once. This became the basic reference for developing a redesign of the automatic cassava pulling tool that was made. Keywords: Automatic, cassava pulling tool, design, the Quality Function Deployment

“…Tab. 1, adapted according to[20], presents the concept of the two-stage model of the second QFD stage used for material selection decisions.This material selection model can be used for each product component or for its systems or subsystems[21]. It connects the design or technical requirements for each product with the material properties and then selects the most suitable material based on a prioritization matrix and correlation links.…”

The inspiration for the research was a customer request for 3D printing of face shield frames during the COVID-19 pandemic. In this context, but also due to the possibilities of relatively cheap 3D printing of various products, a large amount of waste started to be generated that needed to be disposed of. The overall aim of the research was to contribute to the development of new products printed using the 3D Fused Filament Fabrication (FFF) technology from thermoplastic materials, with a view to maximizing the quality level and minimizing the environmental footprint and cost of production. A modified Quality Function Development (QFD) methodology was applied, supplemented by a material planning matrix and a 3D model planning matrix which is the scientific contribution of the research. According to an extended QFD methodology taking into account the particular characteristics of 3D printing quality control and material selection decisions in terms of minimizing environmental impact, frames were printed from biodegradable PHA Biowood 3D Rosa filament. Waste management improvement is proposed by using filaments from biologically degradable materials or recycled filaments.

“…However, as batik printers are highly customized products and are not commonly used, competitive assessment based on customer feedback was not performed to avoid faulty judgment. Several HOQ studies have also been performed without benchmarking and competitive assessments [45,46]. The customer's requirements (CR) for a batik printer include printing speed, the ability to adjust and maintain wax temperature, ease of operation, ability to maintain consistency of wax line thickness and quality, ability to deliver a variety of complex designs, equipment costs, 2D printer size, and maintenance (Room 1).…”

Malaysian batik production is dominated by two techniques known as hand-drawn batik, or batik tjanting, and stamp batik, or batik block. In comparison to batik block, the more popular batik tjanting takes a longer time to produce. A Standardized Nordic Questionnaire (SNQ) for musculoskeletal symptom examination involving batik artisans in Kelantan and Terengganu identified high rates of musculoskeletal disorders in respondents due to their working posture during the batik tjanting process. It was also observed that the number of workers and artisans willing to participate in the traditional batik industry is on the decline. These problems have led to a systematic Quality Functional Deployment approach to facilitate the decision-making process for the conceptual design of an automatic batik printer. In this study, house of quality (HOQ) was applied to identify the critical features for a batik printer based on the voice of the customer (VOC). A survey done to rate the importance of VOC using an 8-point Likert scale revealed that the batik practitioners topmost priority for the batik printer feature is the 'ability to adjust and maintain the temperature of wax' (17.54%) while the non-batik practitioners chose 'ability to deliver a variety of complex designs' (15.94%). The least required feature for the batik printer was related to the size of the batik printer. The mapping between customer requirements (VOC) and technical requirements identified that the extruder design (21.3%), the heating element (18%), and nozzle diameter (17.8%) were the most critical components for the batik printer. Several conceptual designs of the extrusion unit, cartesian-based batik printer, and 2D image conversion using open-sourced software were proposed at the end of this work. ABSTRAK: Pengeluaran batik Malaysia telah didominasi oleh dua teknik yang dikenali sebagai batik lukisan-tangan (batik canting) dan batik cap (batik blok). Sebagai perbandingan, batik canting yang popular mengambil masa lebih lama bagi dihasilkan. Soal Selidik Nordic Standad (SNQ) bagi meneliti gejala muskuloskeletal melibatkan tukang batik di Kelantan dan Terengganu telah menunjukkan persamaan kadar muskuloskeletal yang tinggi pada postur badan semasa bekerja canting batik. Bilangan pekerja yang terlibat dalam industri tradisional batik ini turut terjejas. Masalah-masalah ini telah mengarah kepada kaedah Pengerahan Fungsi Kualiti bagi membantu proses membuat keputusan dalam rekaan konsep pencetak batik automatik. Kajian ini telah mengadaptasi Kualiti Rumah (HOQ) bagi mengesan ciri-ciri kritikal pada pencetak batik berdasarkan suara pelanggan (VOC). Kaji selidik telah dilakukan bagi menilai kepentingan VOC menggunakan skala Likert 8-poin. Didapati keutamaan yang diperlukan oleh 17.54% ahli batik adalah; ciri pencetak batik ini perlu mempunyai ‘keupayaan dalam menyelaras dan menetapkan suhu lilin’, manakala sebanyak 15.94% bukan ahli batik memilih ‘keupayaan pencetak ini harus berjaya menghasilkan pelbagai rekaan yang kompleks’. Ciri yang kurang diberi tumpuan adalah berkaitan saiz pencetak batik. Persamaan antara kehendak pelanggan (VOC) dan kehendak teknikal dalam mengenal pasti komponen-komponen penting bagi pencetak batik adalah rekaan penyemperit (21.3%), elemen pemanas (18%), dan diameter nozel (17.8%). Pelbagai rekaan konsep bagi unit penyemperit, pencetak batik canting, dan imej konversi 2D menggunakan perisian sumber terbuka telah dicadangkan di bahagian akhir kajian ini.
