Abstract

Quality improvement helps companies increase sales and reduce costs, both of which can increase profitability. PP Sinar Tani Palembang is a manufacturing industry engaged in rice milling. Quality control is still very lacking, this is indicated by the data from the scales which entirely pass the prescribed standards of 5 Kg, 10 Kg and 20 Kg. defective products: for 5 Kg packaged rice as much as 0.585 or 58.5%, 10 Kg rice as much as 0.604 or 60.4% and 20 Kg rice as much as 0.612 or 61.2%. It can be seen from the percentage of PP Sinar Tani Palembang every month experiencing a loss of 21,363 Kg or 1,068 kg per day with a nominal value of Rp 228,390.00 per month. By using the Six Sigma method, it is found that there are 2 factors that cause this loss is the occurrence of excess when filling and the balance scales of shear/oil scales used do not have accuracy so that the results of the scales all exceed the specified limit. One proposal that can be done is to replace the balance scales/shear scales/oil scales with digital scales so that the measuring results are more accurate. There was a decrease in the percentage of defects, namely for the weight of 5 kg from 0.585 to 0.166; weight of 10 kg from 0.604 to 0.145; weight of 20 kg from 0.612 to 0.139. Whereas from DPMO the increase from 2 sigma to 3 sigma.

Abstract

Persediaan adalah sumber daya menganggur yang menunggu untuk diproses lebih lanjut. Persediaan bahan baku memiliki waktu penggunaan yang terbatas. Keterbatasan ini disebabkan pertimbangan kerusakan barang. Produk perishable adalah produk dengan beberapa ciri khusus yang membuat persediaannya berbeda dengan jenis produk lainnya. Untuk industri pengolahan makanan, waktu kadaluarsa merupakan masalah yang harus diperhatikan. Selain berdampak pada kesehatan, sifat kadaluarsa suatu produk juga mempengaruhi nilai jual suatu produk. Bakery “X” merupakan salah satu bakery tertua di kota Palembang. Bahan-bahan yang diolah seperti gandum, margarin, mentega, dan telur memiliki batasan waktu pemakaian. Model persediaan produk perishable adalah model yang mengacu pada model Economic Order Quantity (EOQ) dimana kondisi sistem memiliki permintaan yang konstan dan produk yang dapat rusak. Tujuan dari penggunaan model ini adalah untuk menentukan jumlah pemesanan produk yang optimal, kapan melakukan pemesanan, berapa jumlah produk kadaluarsa yang dapat dikembalikan untuk meminimalkan total biaya persediaan. Hasil perhitungan menghasilkan total penghematan biaya persediaan sebesar Rp9.502.349 atau 1,68% per tahun.

Abstract

The increasingly intense competition, the number of customer choice options and the more selective customers in choosing medical equipment products require PT SPU as one of the Indonesian National Medical Device (Alkes) industry engaged in the production process of medical devices and rehabilitation to always improve a better work system. To improve product quality PT SPU has implemented the SNI ISO 9001: 2008 Quality Management System which contains standard requirements used to measure the organisation's ability to meet customer requirements and appropriate regulations. The purpose of this research is to identify and assess how much influence each component of the work system has on the satisfaction of customers, employees and leaders. The method used is Macro Ergonomics. The magnitude of the contribution of the work assessment process of SNI ISO 9001: 2008 implementation to the influence of significant macro ergonomic aspects on organisational conditions (52.45%), physical environment (37.37%), production processes (12.53%), infrastructure (9.69%), production process services (5.90%), and R&D activities (2.82%).(3) Proposed recommendations for improving organisational conditions by confirming the roles and responsibilities of each person so that there are no undisciplined employees between sections, improving communication. Physical work environment by rearranging the place and rejuvenating production process support tools that are not ergonomic and have been damaged, redesigning a conducive and comfortable work environment. Production process improvements including employees actively communicating with each other and development of standard operating procedures (SOPs) with legacy competencies through knowledge transfer. Improvements to Facilities and Infrastructure by adding air conditioning, such as blower/exhaust ventilators, and sufficient room ventilation. Improvements to R&D: by facilitating employee exchanges for R&D activities, training, technical guidance, and experience exchange; increasing access to cooperation with government and private organisations.

Abstract

Manual wheelchairs remain widely used in Indonesian health-care facilities, yet their design often does not fully accommodate local anthropometric characteristics and work patterns. The SM-8018 patient wheelchair used at PT SPU is operated by caregivers, exposing both patients and caregivers to potential ergonomic risks. This study aims to evaluate and redesign the SM-8018 wheelchair using an integrated Ergo-Total Function Deployment (ETFD) and House of Ergonomics (HoE) approach within a Total Ergonomics framework. A pre–post experimental design was applied involving 32 adult users and caregivers with at least six months of experience using or pushing the SM-8018. Data collection included anthropometric measurements, musculoskeletal complaints using the Nordic Body Map (NBM), subjective fatigue using the Japan Association of Industrial Health (JAIH) questionnaire, boredom scores, satisfaction using the Minnesota Satisfaction Questionnaire (MSQ) and voice of customers (VoC). VoC and ergonomic findings were mapped into a HoE matrix to derive priority design specifications through ETFD. Results showed notable mismatches between user anthropometry and key wheelchair dimensions, particularly seat depth and width, backrest and headrest height and angle, and push-handle height, which were associated with high levels of discomfort in the lower back, buttocks, shoulders and upper arms and with considerable fatigue. The ETFD–HoE analysis identified four primary redesign priorities: adjustment of push-handle height, optimisation of backrest and headrest geometry, refinement of seat dimensions and improvement of front-wheel stability. Pre–post comparisons indicated that musculoskeletal complaints and fatigue remained relatively high and in some cases increased, whereas boredom and satisfaction tended to change in a more favourable direction. These findings suggest that the first iteration of the SM-8018 redesign, although guided by Total Ergonomics principles, requires further refinement and system-level support. Nonetheless, the study demonstrates the feasibility of integrating ETFD, HoE and Total Ergonomics to systematically guide the improvement of low-cost hospital wheelchairs in the Indonesian context.
