Abstract

Every company desires a profit, and its production system must continually develop and become more productive. Companies can boost their production productivity in a variety of ways, including by enhancing their production process system and removing impediments. This research was conducted at a company in Tangerang that specialized in manufacturing brake linings. On the basis of the results of field research, manufacturing department defects and inventory have been detected. The research phases employ the DMAIC model. The define phase employs SIPOC and CTQ diagrams. Using WAM to identify waste that happens through the distribution of questionnaires during the measurement phase. According to the measure stage's calculation, the company's current efficiency level is 26.85 percent. The DPMO value is 6,222.71 and sigma number indicates a quality level of 4.91. After learning the company's status, the research continued with an FMEA examination of the root cause. On the basis of the results of the analysis, proposals for changes to the brake linings production steps were made. The research was continued in the third phase, known as control, which consisted of recalculating the company's status after the implementation of modifications. The calculation findings demonstrate an increase in process cycle efficiency to 35.33 percent. In addition, a reduction in the value of faults per million opportunities resulted in the production of 4,524.88 products and an increase in the sigma level to 5.12. This demonstrates a gain in efficiency of 8.48%, a drop-in DPMO of 1,697.83 products, and a 0.21 increase in sigma value.

Abstract

Infeksi Saluran Pernafasan Akut (ISPA) merupakan kondisi kesehatan yang ditandai dengan infeksi pada saluran pernafasan bagian atas yang menyebabkan gejala seperti batuk, pilek dan demam. Penyakit ini sangat mudah menular terutama pada anak-anak dan orang dewasa lanjut usia. Beberapa faktor yang memicu ISPA antara lain kondisi cuaca, tingginya tingkat polusi udara, dan pencemar udara dari sumber tertentu. Perkembangan teknologi memungkinkan masyarakat mengakses informasi kesehatan secara mandiri tanpa harus ke rumah sakit. Hal ini membantu masyarakat mendapatkan informasi awal penyakit dan mencegah penularan di RS. Penerapan sistem pakar dirancang untuk memberikan informasi diagnosis awal ISPA kepada masyarakat. Sistem ini berfungsi membantu dokter dalam pengambilan keputusan diagnosis secara otomatis. Sebelumnya diagnosis hanya bisa dilakukan langsung dengan dokter yang menimbulkan berbagai kendala. Oleh karena itu, metode certainty factor digunakan sistem pakar untuk memperoleh diagnosis berdasarkan gejala dan keahlian dokter.

Abstract

Nowadays, more and more SkinCare is emerging from countries around the world which then results in SkinCare trends. Various Skincare Brands have sprung up on the Shopee e-commerce site and one of them is the Garnier Skincare Brand. This study seeks to explore how the influence of Flash Sale, Cashback, Free Shipping on purchasing decisions for Garnier products at Shopee. This study uses quantitative data analysis methods using Structural Equation Modeling (SEM) based on Partial Least Square (PLS) with the help of SmartPLS 3.0 software. Primary data was collected by distributing questionnaires to 180 consumers who shop for garnier skincare using the Shopee application and live in Cirebon City. The results showed that flash sales had a significant effect on purchasing decisions with a T table value of 12.480 and a p value of 0.000, as well as cashback had a significant effect on purchasing decisions with a T table value of 6.020 and a p value of 0.000 and finally free shipping also had a significant effect on purchasing decisions with a T table value of 10.020 and a p value of 0.000.

Abstract

Food quality is very important so that food processing must be done properly to ensure food safety, namely by implementing the HACCP system. HACCP is often considered a complex system so that not many companies use it. This study aims to prevent hazards that may arise using the HACCP system and evaluate the quality control of shrimp crackers to reduce defective products.. This study uses a case study approach to a small and medium-sized company that produces raw shrimp crackers. Data were collected through literature reviews, interviews, and observations. The techniques used are quality control, Good Manufacturing Practices – GMP, Sanitation Standard Operating Procedure – SSOP, and Hazard Analysis Critical Control Point – HACCP. The results of the quality control analysis show that products that are included in the Not Good category have the characteristics of being incomplete, untidy, clean, not uniform, and of uneven thickness. The GMP & SSOP analysis results show that this company is at level IV, and is included in the "Unfit" category and HACCP analysis show that there are three processes included in the Critical Control Point (CCP), namely storage of raw and packaging materials, drying, and storage of finished materials. Suggestions for improvement are this company needs to pay more attention to quality control, improves the implementation of GMP and SSOP so that they can reach Level I in GMP and the "Meet" category in SSOP, and only then can implement the HACCP plan.

Abstract

The objective of this research is to develop prioritized indicators for companies by designing performance measurement using the Green Supply Chain Management (GSCM) approach, Key Performance Indicators (KPI), Supply Chain Operations Reference (SCOR) model, Objective Matrix (OMAX), and Traffic Light System to analyze environmentally friendly logistics strategies and concepts in support of corporate sustainability and efficiency. This study was conducted on a footwear manufacturing company. The performance measurement design, based on the green supply chain management concept aligned with the company's vision and mission, resulted in the identification of 45 key performance indicators. The company then selected 20 indicators out of the 45 proposed for further modeling using the Green SCOR method, which includes five perspectives: plan, source, make, deliver, and return. Performance scores were then calculated using the Objective Matrix (OMAX) and the Traffic Light System. The results showed that 12 indicators were marked green, 6 were yellow, and 2 were red. Each perspective received a score as follows, return 9.090, delivery 8.402, source 7.589, make 7.333, and plan 6. The plan perspective received the lowest score, indicating that immediate improvements should be made in the plan perspective, particularly regarding unmet indicators, to achieve the company’s performance targets.

Abstract

This manufacturing company operates in the automotive industry with a Make to Order (MTO) production system, producing motorcycle engine components. Observations revealed production inefficiencies due to waste in the form of waiting time and excessive motion, leading to increased operational time and costs. This study aims to identify sources of waste, analyze root causes, and propose improvements using the Green Lean Manufacturing approach, which emphasizes both production efficiency and environmental considerations. The methods applied include Value Stream Mapping (VSM), Fishbone Diagram, 5 Why’s analysis, and system dynamics simulation. Based on the Current VSM analysis, the lead time was 268.21 minutes with a Process Cycle Efficiency (PCE) of 77.32%. Proposed improvements include relocating materials closer to machines, preparing tools before production, and adding workplace facilities. The Future VSM showed a lead time reduction of 17.92 minutes and a PCE increase of 1.17%. From the three simulated scenarios, ANOVA test results indicated that Scenario 3 was the most effective in reducing motion waste, while Scenario 2 best reduced waiting time. Both scenarios demonstrated the effectiveness of continuous lean implementation over a five-year period.
