Single-sided lapping is one of the most effective planarization technologies. The process has relatively complex kinematics and it is determined by a number of inputs parameters. It has been noted that prediction of the tool wear during the process is critical for product quality control. To determine the profile wear of the lapping plate, a computer model which simulates abrasive grains trajectories was developed in MATLAB. Moreover, a data-driven technique was investigated to indicate the relationship between the tool wear uniformity and lapping parameters such as the position of conditioning rings and rotational speed of the lapping plate and conditioning rings.

Various problems that occur related to the use of a management accounting system (SAM) that has not been maximized resulted in a decrease in product quality that is influenced by various conditions of environmental uncertainty. This study aims to determine and analyze the effect of broad scope, timeliness, aggregated and integrated SAM on product quality control with environmental uncertainty as a moderating variable at PT. SINAR SOSRO KPB PALEMBANG. The results of this study indicate that partially it is known that SAM Broad Scope, SAM Aggregated, and SAM Integrated significantly influence Product Quality Control, whereas SAM Timelines does not significantly affect the variable Quality Control. Simultaneously it is known that SAM Broad Scope, SAM Timeliness, SAM Aggregated, and SAM Integrated significantly influence Product Quality Control. Partially, it is known that Environmental Uncertainty does not significantly moderate the relationship between SAM Broad Scope, SAM Timeliness, SAM Aggregated, and SAM Integrated on Product Quality Control, and all moderation relationships what happens is the moderator predictor. The influence between SAM Broad Scope, SAM Timeliness, SAM Aggregated, and SAM Integrated significantly influence Product Quality Control with Environmental Uncertainty proved to be strong where Adjusted R Square value of 0.684 or 68.4% while the remaining 31.6% is explained by other factors outside the research model.   Abstrak Berbagai permasalahan yang terjadi terkait penggunaan sistem akuntansi manajemen (SAM) yang belum maksimal mengakibatkan penurunan kualitas produk yang dipengaruhi oleh berbagai kondisi ketidakpastian lingkungan. Penelitian ini bertujuan untuk mengetahui dan menganalisis pengaruh cakupan luas, ketepatan waktu, agregat, dan SAM terintegrasi terhadap pengendalian kualitas produk dengan ketidakpastian lingkungan sebagai variabel moderasi pada PT. SINAR SOSRO KPB PALEMBANG. Hasil penelitian ini menunjukkan bahwa secara parsial diketahui bahwa SAM Broad Scope, SAM Aggregated dan SAM Integrated berpengaruh signifikan terhadap Product Quality Control, sedangkan SAM Timelines tidak berpengaruh signifikan terhadap variabel Quality Control. Secara simultan diketahui bahwa SAM Broad Scope, SAM Timeliness, SAM Aggregated dan SAM Integrated berpengaruh signifikan terhadap Pengendalian Kualitas Produk. Secara parsial diketahui bahwa ketidakpastian lingkungan tidak secara signifikan memoderasi hubungan antara SAM Broad Scope, SAM Timeliness, SAM Aggregated dan SAM Integrated, terhadap pengendalian kualitas produk, dan semua hubungan moderasi yang terjadi adalah moderator predictor. Pengaruh SAM Broad Scope, SAM Timeliness, SAM Aggregated dan SAM Integrated berpengaruh signifikan terhadap Pengendalian Kualitas Produk dengan Ketidakpastian Lingkungan terbukti kuat dimana nilai Adjusted R Square sebesar 0.684 atau 68.4% sedangkan sisanya sebesar 31.6% dijelaskan oleh faktor lain di luar penelitian. model. Kata kunci: SAM Broad scope, SAM Timeliness, SAM Aggregated, SAM Integrated, Ketidakpastian Lingkungan, Pengendalian Kualitas Produk.
