Implementasi Perbaikan Proses Spot Welding melalui Integrasi Teknologi Industri 4.0 dan Pokayoke untuk Meningkatkan Kualitas dan Stabilitas Produksi

Adidya Rangga Pratama — 2026-01-02

PT X faced quality challenges in its spot-welding process, resulting in a high product defect rate and reduced competitiveness. Reliance on manual processes led to inconsistencies, which impacted customer satisfaction and the company's reputation. To address this issue, researchers initiated an Industry 4.0 based transformation with a Six Sigma approach. Improvements were made by implementing servo robots to automate the spot-welding process. This step was accompanied by modifications to the jig, the use of Jundate pallets, and the adoption of Zirconium cup tips to overcome downtime due to sticking. As a result, the company succeeded in significantly reducing the DPMO from 255 to 12, increasing productivity by 16%, and generating significant annual cost savings. In addition to tangible benefits, these improvements also resulted in increased customer trust, the acquisition of new projects, and an improved corporate image.

Analisis Keberlanjutan Sistem Pengelolaan Sampah Berbasis 3R (Studi Kasus MRF, TPST Kota Hijau, dan Bank Sampah Kota Hijau Balikpapan)

As a buffer zone for the new National Capital (IKN), Balikpapan City is experiencing rapid population growth accompanied by increasing waste generation. In 2023, the city produced 528.87 tons of waste per day, an increase of 2.74% from the previous year. Projections indicate that the Manggar Landfill will reach full capacity by 2026, rendering it unable to accommodate additional waste. To address this issue, in 2017 the Balikpapan City Government, in collaboration with the Ministry of Environment and Forestry (KLHK) and JICA, implemented a 3R-based waste management program through the integration of Material Recovery Facilities (MRF), Integrated Waste Processing Facilities (TPST), and the Waste Bank Program. This study aims to analyze the factors influencing the sustainability of the waste management system at the MRF, TPST Kota Hijau, and Kota Hijau Waste Bank, and to formulate appropriate development strategies. The research applies Multidimensional Scaling (MDS) with the RAPFISH approach combined with SWOT analysis. The results show that the Kota Hijau Waste Bank has the highest sustainability status, supported by financial independence and strong community participation, and is classified as fairly sustainable. The MRF is also considered fairly sustainable but remains highly dependent on the municipal budget. Meanwhile, the TPST Kota Hijau records the lowest sustainability level due to operational-technical challenges and limited community involvement. Overall, the three infrastructures fall within the fairly sustainable category. To advance their status to sustainable or highly sustainable, several strategic measures are required, including the optimization of local policies and regulations, program synchronization across stakeholders, strengthening institutional and human resource capacities, diversifying funding sources, enhancing community engagement, and improving technical-operational performance.

Analisis Variabel Penentu Keberlanjutan TPA Jalupang Kabupaten Karawang: Perspektif Masyarakat melalui Structural Equation Modeling (SEM)

Ninne Sevtiana Dewi — 2025-09-28

Jalupang Landfill is the only official final disposal facility in Karawang Regency, which is still operated using an open dumping system. This management practice has created several environmental issues, including a fire incident in October 2023, and has raised concerns about the sustainability of its operations. This study was conducted to identify the variables that influence the sustainability of Jalupang Landfill by employing a reflective Structural Equation Modeling (SEM) approach. Primary data were collected through questionnaires distributed to 100 respondents across nine districts who are involved in waste transportation to the landfill. The questionnaire applied a Likert scale and was analyzed using SmartPLS 4.0 through a series of tests, including model fit, construct validity, and path coefficient analysis. The results indicated that the developed model met the fit criteria, with an R² value of 0.622 or 62.2%. The regulatory variable was found to be the most dominant factor, with a path coefficient of 0.400 (p-value = 0.002), followed by the financing variable with a coefficient of 0.286 (p-value = 0.041). These findings highlight that the sustainability of Jalupang Landfill is largely determined by strengthening regulatory aspects and ensuring adequate financial support.
