Tujuan dari penelitian ini adalah untuk mencapai pengurangan biaya dan peningkatan kualitas di Industri Manufaktur Kereta Api dengan menerapkan tahap define, measure, analyze, improve and control (DMAIC) dari Six Sigma. Penerapan metode DMAIC dilakukan di sebuah perusahaan manufaktur komponen kereta api di Indonesia yang memproduksi Single Part Side Frame sebagai objek penelitian. Penyebab dari tingginya cacat produk diketahui pada tahap define. Pada tahap measure, detail dari data lapangan dikumpulkan dan level sigma ditentukan. Penelitian ini menggunakan diagram fishbone untuk mengetahui penyebab permasalahan yang terjadi dan dianalisis sehingga diketahui bahwa permasalahan material terjadi akibat penyimpanan material pada ruang terbuka yang meningkatkan potensi korosi pada material baja ST52. Hasil dari analisis solusi permasalahan menggunakan metode 5W+2H didapatkan solusi untuk perbaikan penyimpanan material dan layout penyimpanan material. Selain itu, perbaikan juga dinilai dari tingkat korosi material pada sebelum dan sesudah perbaikan berdasarkan kandungan kimia material baja ST52. Perbaikan dengan menggunakan pendekatan DMAIC ini perlu dilakukan pada tahap improve agar dapat melakukan perbaikan secara terus menerus. Hasil dari penelitian mampu menurunkan tingkat korosi berdasarkan peningkatan level sigma dari 0,66 menjadi 2,40 dan cost of quality yang signifikan sebesar Rp. 39.100.000.

Efforts to support the provision of fast public services, for that we need a government system that supports the creation of quality public service delivery. This research was conducted to determine the factors that determine and influence community satisfaction in Palembang City samsat. The factors studied were the influence of service quality, service procedures, work environment, and policy implementation on community satisfaction partially and simultaneously. This research was collected by sampling techniques using purposive sampling which is part of nonprobability sampling with the help of research instruments in the form of 124 sheets / respondents which were distributed directly to the SAMSAT Office of Palembang City aimed directly at the people in the office. in this study analyzed using multiple linear regression models with the help of SPSS version 22.0 software. The results are estimated to have the effect of independent variables on dependents both partially and simultaneously. The dominant coefficient of influence on satisfaction is Policy Implementation of 0.288 and the lowest is the service procedure of 0.181. The independent variable can explain 48% (R2, RSquare) and the remaining 52% is influenced by other factors not included in this study.

After the COVID-19 pandemic, the government experienced a new challenge, namely restoring public trust in the government due to the reduction of individual freedom of the community based on emergency crisis conditions. This study focuses on explaining (1) the dynamics of public trust in the government in the post-pandemic phase (2) the tendency of the government to take strategic steps on a top-down basis so that it threatens individual freedoms affected by applicable policies and regulations (3) frameworks that can be applied to build public trust so that collaboration between sectors in dealing with the after effects of the pandemi can be achieved. The research method used in this article is a Systematic Literature Review by collecting primary data sourced from accredited journal articles and media news sources. The results of this study reveal that civil liberty in an emergency is limited and this has an impact on the crisis of Indonesian people's confidence in the government and has logical consequences for public stability in responding to policies. At the end of the discussion, the researcher offers a framework to build public trust after the COVID-19 pandemic that is oriented towards citizen engagement.
