Abstract

Persaingan ketat di sektor Industri telah memaksa setiap perusahaan untuk berinovasi pada produknya. Sebagai salah satu hasil penelitian dan pengembangan di sektor industri, prototipe memainkan peran untuk mendukung terciptanya inovasi produk. Tujuan penelitian ini adalah untuk memodelkan dampak belanja, jumlah personil, skema jenis kerjasama litbang dan skala industri terhadap status penciptaan prototipe dalam lingkup industri. Analisis dilakukan pada data hasil Survei Litbang Industri Indonesia tahun 2021 melalui regresi logistik. Adapun regresi yang dilakukan menggunakan stepwise untuk menghasilkan model dengan variabel yang memiliki tingkat signifikansi terbaik. Hasil penelitian menyebutkan bahwa jumlah personil litbang, skala industri, kerjasama SDM dengan institusi asing dan kerjasama pendanaan dengan pemerintah pusat menjadi faktor yang signifikan dalam menghasilkan luaran prototipe. Industri skala menengah cenderung lebih banyak menghasilkan prototipe jika dibandingkan skala besar. Adapun kerjasama pendanaan dari Pemerintah Pusat merupakan aspek yang memiliki signifikansi paling tinggi dalam mempengaruhi luaran prototipe. Investasi SDM litbang yang kompeten bisa menjadi solusi untuk mengantisipasi kecilnya nilai odds ratio pada variabel jumlah SDM litbang. Selain itu, otoritas yang berwenang perlu terus meningkatkan ekosistem pendanaan riset industri yang lebih baik. [Logistic Regression Model of Prototype Creation as an Output of Industrial R&D Activities] Intense competition has forced every company to innovate its products. As one of the research and development outputs in the industrial sector, prototypes play a role to support the creation of product innovation. The purpose of this study is to model the impact of expenditure, number of personnel, type of R&D cooperation scheme and industry scale on the status of prototype creation in the industrial scope. The analysis was carried out on the data from the Indonesian Industrial R&D Survey 2021 through logistic regression. The regression was carried out using stepwise to produce the best model. The results stated that the number of R&D personnel, industry scale, HR cooperation with foreign institutions and funding cooperation with the central government were significant factors in producing prototype output. Medium-scale industries tend to produce more prototypes than large-scale ones. Funding cooperation from the central government is the aspect that has the highest significance in influencing prototype output. Investment in competent R&D human resources can be a solution to anticipate the small value of the odds ratio on the variable number of R&D human resources. In addition, the competent authority needs to continue to improve a better industrial research funding ecosystem.Keywords: industrial R&D; prototypes; R&D expenditure; R&D personnel; R&D cooperation; R&D resources

Abstract

The poor and hazardous work conditions of small businesses are prevalent, including the Indonesian small food-producing businesses. Observations have been commonly used to examine and describe the work conditions, although with some limitations. Despite the seemingly useful application, the ILO-PATRIS and its IPR calculation have not been used to observe the work conditions of Indonesian small food-producing businesses. This study aimed to demonstrate the applicability and usefulness of ILO-PATRIS, as an instrument to observe the working conditions of  Indonesian small food-producing businesses. A small business of tempe chips was purposively selected, with three respondents involved in the scoring of the ILO-PATRIS monitoring items. The results indicated relatively poor working conditions with ILO-PATRIS score of 30 out of 58. The IPR calculations led to the understanding that several aspects could be improved, such as the personal protective equipment and physical environment. This study demonstrated that the ILO-PATRIS and its IPR calculation are useful in observing the working conditions of an Indonesian small food-producing business. However, some recommendations of the use should be considered, which may be investigated in further studies.

Abstract

The implementation of Six Sigma methodology has demonstrated significant effectiveness in enhancing quality and reducing defects in manufacturing processes. This study examines the application of Six Sigma principles to minimize defects in automotive cylinder block production. Employing the Define, Measure, Analyze, Improve, and Control (DMAIC) framework, the research identifies critical factors contributing to defects and implements strategic improvements to address quality issues. The Define phase established key elements related to quality products, including processes, suppliers, customers, and their requirements, utilizing SIPOC diagrams and Critical to Quality (CTQ) factors. In the Measure phase, data collection focused on determining process baselines and root causes, employing Defects Per Million Opportunities (DPMO) and Control Charts. Analysis revealed a DPMO value of 4,987 with a sigma level of 4.077σ. The Analyze phase identified causes of production process failures, with "Sunakui" (sand hole) emerging as the predominant defect type in cylinder block production. The study concluded that unsuitable sand composition was the root cause leading to defects. To address this issue, the research recommends implementing a Poka-Yoke system with an integrated alarm to monitor and ensure appropriate sand composition, thereby enhancing overall product quality.

Abstract

Prolonged length of stay (LOS) in emergency departments (EDs) negatively impacts patient care and operational efficiency. This study applies simulation modeling using ARENA software to analyze and optimize ED operations at Anna Medika General Hospital in Madura, Indonesia. Three improvement scenarios were evaluated: adding one nurse, one bed, and one general practitioner. The results show that adding a general practitioner reduced LOS significantly, from 184.64 minutes (3.08 hours) to 154.37 minutes (2.57 hours), making it the most effective intervention. However, the findings emphasize the importance of a holistic approach, as standalone interventions may only address isolated bottlenecks. Combining targeted staffing increases with process optimizations provides the most sustainable improvements. This study highlights simulation’s value in evaluating operational strategies, enabling hospitals to make data-driven decisions that balance cost, resource allocation, and patient satisfaction.
