Abstract

Research on new product development (NPD) has led to tools, methods, models, and frameworks that enable researchers to develop better products. However, a comprehensive review of the methods, models and frameworks related to NPD is lacking. This literature study aims to identify research trends, methods, and frameworks used in NPD between 2010 and 2019. A systematic literature review is conducted by developing a structured research protocol. An analysis of 50 selected papers shows that research on NPD can be categorized into 15 conceptual papers, six review papers, 28 case studies, and one survey paper. This paper provides an overview of each tool and presents future research opportunities. This paper concludes that future research can be directed toward combining several methods to design products that satisfy consumer desires with shorter design times, aspects of NPD collaboration, and aspects of changing consumer preferences.

Abstract

This study examines the impact of live verification as an innovative approach to local content verification at PT Pertamina Hulu Energi (PT PHE), by comparing its efficiency and effectiveness against conventional verification methods. By analyzing 207 contracts (verified in 2022-2024), this study documents the transition from conventional verification (50 contracts in 2022) to live verification (71 contracts in 2023, 77 contracts in 2024), with little retention of conventional methods (4 and 5 contracts respectively). By applying Business Process Re-engineering (BPR), this study aims to demonstrate significant process simplification, reducing verification steps from 9 steps to 6 steps and consolidating 4 steps into 1 step. Furthermore, statistical tests were conducted to validate the significant changes before and after the live verification method was implemented. Including homogeneity test and one-way ANOVA was chosen because it was considered suitable by involving three independent variables (2022, 2023, 2024) and the dependent variable which is verification time (SLA). Statistical validation through descriptive frequency analysis showed that the average verification processing time in 2023 (25,45 working days) and 2024 (14,55 working days) was getting closer to the ideal benchmark. Furthermore, homogeneity testing and one-way ANOVA confirmed a statistically significant improvement, with significance values of <0.001 (by mean) and 0.001 (<0.05 for ANOVA), indicating a substantial reduction in SLA post-implementation. Then the implementation of verification is measured by the effectiveness test and the results show that in 2023 & 2024 the live verification process is considered effective with a cumulative achievement rate of 32%, and in terms of efficiency it is considered efficient with a cumulative achievement rate of 87,18%. This live verification method can be an effective solution to speed up the local content verification process and help solve problems in the local content verification process. The findings underscore live verification as a transformative strategy, improving process agility, cost efficiency, and compliance performance. This research contributes to the production process literature by offering a data-driven framework for process optimization, as well as actionable insights for energy sector policymakers and potential scalability in the context of global supply chain compliance.

Abstract

Perkembangan teknologi printer 3D untuk medis, memungkinkan aplikasi produksi implan pra-operasi dengan keunggulan akurasi geometri yang baik, mengurangi waktu operasi dan resiko kehilangan banyak darah. Teknologi printer 3D paling populer dan potensial untuk dikembangkan masal di Indonenesia adalah fused deposition modeling/FDM. Akan tetapi memiliki kekurangan: single material, jenis material terbatas dan temperatur yang tinggi sehingga tidak bisa dicampur dengan material/senyawa bioaktif yang sensitif terhadap panas. Pengembangan metode injection moulding berbasis printer 3D telah dilakukan pada penelitian ini dengan melakukan modifikasi alat, material, tahapan dan sistim produksi implan pra-operasi yang mengacu pada teknologi printer 3D untuk cranioplasty yang sudah dilakukan di negara maju. Untuk memastikan modifikasi ini bisa menghasilkan implan pra-operasi dengan akurasi geometri yang diinginkan, dilakukan karakterisasi terhadap deviasi dimensi implan yang diproduksi yaitu deviasi volume, deviasi tebal, deviasi panjang linear dan deviasi sudut kelengkungan permukaan implan, pada dua metode berbeda yang diuji, yaitu metode cranial/intra operatif dan metode injection moulding dengan menggunakan material polymethylmethacrylate/ PMMA. Hasil yang didapatkan adalah deviasi volume implan yaitu sebesar 1.87 ± 1.27 % (injection moulding) dibandingkan 11.39 ± 3.71 % (metode cranial), deviasi tebal sebesar 2.54 ± 0.86 % (injection moulding) dibandingkan 7.35 ± 1.43 % (metode cranial), deviasi panjang linear sebesar 2.61 ± 0.47% (injection moulding) dibandingkan 5.76 ± 0.79 % (metode cranial) dan deviasi sudut kelengkungan permukaan sebesar 0.98 ± 0 % (injection moulding) dibandingkan 15.45 ± 3.94 % (metode cranial). Dapat diambil kesimpulan bahwa metode injection moulding lebih baik daripada metode cranial/intra operatif. Manufacture of pre-surgery implant may shorten the surgery duration and blood loss risk which provide medical benefit for patient. Additive manufacturing technology (AMT) have been applied in manufacture of pre-implant for cranioplasty surgery. Application of AMT allows production of pre-surgery implant with good geometrical accuracy. The most popular and potential printer 3D technology for mass developed in medical, is fused deposition modeling/FDM, because capable of producing its porosity high with a pattern laydown and the mechanical force good. However, FDM technology have some drawbacks i.e. the use of single type material, limited types of materials, and operation at high temperatures. This research was conducted to develop pre-surgery implants based on additive manufacturing technology to reconstruct and redesign cranial bone defects in Indonesia. This research produced 3D printer-based of injection moulding method by modifying tools, materials, steps, and pre-surgery implants production system based on the additive manufacturing for cranioplasty. Geomatrical accuracy of implant was measured in term of volume deviation, thickness deviation, linear length deviation and surface curve angle deviation of implants. The study comparing two different methods tested: cranial/intra-operative method and injection moulding method using PMMA material. The result showed that implant manufactured by 3D printer based mould have a higher geometrical accuracy as compared to cranial method. Volume deviation on the produced implants is 1.87 ± 1.27 % (injection moulding) compared to 11.39 ± 3.71 % (cranial method), thickness deviation of 2.54 ± 0.86 % (injection moulding) compared to 7.35 ± 1.43 % (cranial method), linear length deviation of 2.61 ± 0.47% (injection moulding) compared to 5.76 ± 0.79 % (cranial method), curve length deviation of 1.54 ± 0.77% (injection moulding) compared to 6.34 ± 0.99 % (cranial method) and surface curve angle deviation of 0.98 ± 0 % (injection moulding) compared to 15.45 ± 3.94 % (cranial method). From the data, it can be concluded that the injection moulding method is better suited than the cranial/intra-operative method.
