Judul: Penjadwalan Pekerjaan dan Sistem Kanban pada PT Toyota Motor Manufacturing Indonesia
Abstrak: Toyota Production System (TPS) dikenal sebagai sistem produksi terbaik dalam mengelola manufaktur. Tujuan magang ini adalah mempelajari penerapan praktik TPS pada Divisi Stamping PT Toyota Motor Manufacturing Indonesia (TMMIN), serta memberi usulan pada permasalahan yang ada, yaitu adanya keterlambatan pengiriman press part yang dicek dan diperbaiki oleh Quality Gate. Analisis 5 Whys menemukan bahwa akar permasalahannya adalah Quality Gate belum memiliki panduan urutan pekerjaan. Perbaikan yang diusulkan adalah pembuatan panduan urutan pekerjaan yang diberi nama “Pattern Quality Gate” untuk Outlet 1. Pattern dibuat berdasarkan metode pengurutan pekerjaan Earliest Due Date). Pattern dilengkapi oleh sistem kanban sebagai instruksi kerja untuk meningkatkan manajemen visual pada sistem produksi Quality Gate. Hasil implementasi pattern adalah Quality Gate melakukan pengecekan dan perbaikan sesuai urutan. Hasil implementasi sistem kanban adalah kondisi normal atau abnormal pada sistem produksi di Quality Gate dapat terlihat.

Judul: Implementasi Toyota Business Practices (TBP) dalam Analisis Peningkatan Akurasi Sistem Manajemen Material (Studi Kasus : Material F1 atau Pigmen)
Abstrak: Although it has been supported by various kinds of modern facilities in a production system, PT Toyota Motor Manufacturing Indonesia (TMMIN) still face problems in material management system. Fluctuations in unit cost per vehicle produced from Toso Shop in each month are one of the problems faced by PT TMMIN. In addition, there are also differences between the monthly reports of the item budget control with the actual use of some materials. Hence, it is necessary to analyze the situation in order to improve the accuracy of the material management system. TBP are measures used by Toyota in solving a problem in an effective and focused way. TBP consists of 8 stages: Problem Clarification, Breakdown Analysis, Target Setting, Root Cause Analysis, Countermeasure, See Countermeasure Through, Evaluation, and Standardization. Based on the number of steps to analyze the problems of accuracy, it is known that the material that has the lowest accuracy is F1 material (pigment) with 69.45% accuracy level. This caused bycheck sheet filling that are not orderly carried out. The solution of theproblem is by making new check sheet and developing Standard Operating Procedure’sfor sheet filling. The changes in the new check sheet is related with some additional explanation in the form of information-time option, the symbol A-Z, formula calculation, Bulk filling column, the column totals and summary columns in a month.

Judul: Durability of Specific Immunoglobulin (Ig) Y Againts Influenza and Covid-19 in Sunscreen
Abstrak: The benefit of specific immunoglobulin Y (Ig Y) as an active ingredient in personal care products such as sunscreen has not been properly studied. Our study aims to evaluate the reliability of specific IgY against influenza and the COVID-19 virus in a sample sunscreen product. Specific IgY influenza and COVID-19 viruses were inserted in the sample sunscreen at two concentrations of 0.1% and 0.25%. Three treatments were observed: control (C) sunscreen without IgY, treatment 1 (T1) sunscreen with 0.1% IgY, and treatment 2 (T2) sunscreen with 0.25% IgY. Organoleptic observations were carried out to monitor changes in aroma, color, and texture, and sunscreen sampling was done every week for 6 weeks. The durability of IgY was evaluated using an enzyme-linked immunosorbent assay (ELISA) and a neutralization assay. Organoleptic observation from weeks 1 to 6 showed consistency in its aroma, color, and texture. Enzyme-linked immunosorbent assay and neutralization assay (NA) results of the T1 and T2 groups showed negative results except for sample T1 at week 5, which showed a positive result in the Influenza A ELISA. Based on the results, it seems that IgY concentrations of 0.1% or 0.25% were not optimal. However, this negative result might be due to low concentration of the IgY and the presence of beeswax, which inhibits IgY and causes it to dissolve in distilled water, thus preventing it from being detected in the assay.
