PT. Telkom Indonesia is the largest telecommunications provider in Indonesia which has been serving the country for about 160 years. As the company grows, the range of service it provided also improved, starting from just a fixed line provider to internet and IP TV. Telkom always follows what its customers need. However, the occurrence of problem cannot be avoided. Problems can always appear from many aspects either it is controllable and uncontrollable. To provide the best service, Telkom offers the services to fix and repair any problem faced by its customers, but this is not an easy task, until today Telkom has not yet been able to meet the Service Level Guaranteed which it promised to its customers. There are also many outstanding tickets unresolved even when Telkom has many human resources. Therefore, this research aims to reduce the time required to fix problems and solve tickets through lean methodology for service by implementing value stream mapping and eliminating as well as improving the non-value-added activities and non-value-added but necessary. Through this approach, this paper assumes that currently it is highly possible to achieve the service level guaranteed as long as improvements are made.

The production process of the garment industry with socks products in a company often has problems with a decrease in machine productivity. Production results still cannot reach the production target and result in disruption of delivery to customers. This study aims to determine the main causes that affect the decline in production and provide solutions to increase production. The method used in this research is the Plan-Do-Check-Action (PDCA) approach and the Overall Equipment Effectiveness (OEE) method. This method is appropriate in analyzing increased production and measuring the effectiveness of the use of equipment in production efficiency. The results of this study can determine the main causes that affect production decline using Failure Models and Effects Analysis (FMEA), namely, the standard speed fluctuates 336 RPN, medium speed 245 RPN, sloping creel 150 RPN, narrow engine room 120 RPN, and dirty engine 72 RPN. The measurement of the effectiveness of the use of equipment in terms of production efficiency (OEE) before the repair is 63% and after modification is 73%, meaning that the OEE value after the change has increased by 8%. This is evidenced by an increase in production output by 112% on an average per machine/month.

The scope of this research is in one of the textile industries with elastic tape produced on the weaving machine, which has decreased production due to production defects that do not meet the target. This research aims to determine the leading causes of dominant defects, increase the sigma level with Six Sigma methods, and propose improvements to be included in the Key Performance Indicators (KPI) method. The results of this study that the dominant factor causing the defect is the curved elastic tape defect, which consists of the machine factor, and the method. Factors driving the machine include the hook like a side thread lock that is often bent and the difference in the thickness of the tape between the left, middle and right. The causative factor of this method is checking the thickness of the elastic band only in the center position. The results of corrective actions impact increasing the sigma level by 10% from 3.3339 to 3.6832. In contrast, repair defects can reduce defects before repair by 18.92% and after repair by 9.23%. It is proposed to be included in the KPI so that the weaving department can control and be enthusiastic about continuous improvement.

Salah satu jenis pemborosan yang masih cukup dominan dalam industri nasional adalah terjadinya proses atau produk atau kegiatan yang tidak memiliki nilai tambah. Pendekatan modern yang menggunakan statistik untuk mencapai tingkat cacat yang sangat rendah bahkan menuju nol cacat seperti metode DMAIC telah banyak diterapkan di Indonesia. Penerapan metode DMAIC yang terstruktur dan berkelanjutan akan mampu mengurangi tingkat kecacatan pada proses dan produk. Penurunan kualitas yang terjadi pada produksi di pertambangan batubara Indonesia, yang berapa tahun belakangan ini berkurang. Hal ini menyebabkan turunnya posisi Indonesia pada ekspor batubara. Penelitian ini bertujuan untuk memperbaiki kemampuan proses pada salah satu industri pertambangan batubara di Indonesia dengan menerapkan metode DMAIC berbasis Ilmu Statistika. Pendekatan yang digunakan adalah melalui tahapan terstruktur DMAIC dengan target keluaran pada setiap tahapan. Penerapan metode DMAIC dapat mengurangi variasi keluaran, sehingga tidak melebihi enam standar deviasi antara nilai rata-rata dan batas spesifikasi terdekat. Hasil yang diperoleh pada penelitian ini adalah peningkatan kappabilitas proses dari 2,25 sigma menjadi 2,52 sigma.

Indonesia is one of the four-wheeled vehicle manufacturers in ASEAN and is a country that is developing dramatically in the automotive sector. The ongoing challenge faced as a manufacturer of four-wheeled vehicles now is how the industry continues to improve quality and reduce waste activities in the production process in order to have a strong competitiveness in the era of increasingly fierce competition today. Lean Six Sigma is a systematic data-driven methodology that integrates two powerful business improvement strategies to improve product quality and reduce waste. In this context, this study uses the Lean Six Sigma framework with the DMAIC methodology approach with the aim of improving the quality of the process and reducing waste of defect products along the four-wheeled vehicle assembly line.. The industrial case study was carried out in one of the four-wheeled vehicle manufacturers in the GIIC Indonesia industrial area. It begins with identifying the waste that occurs with values stream mapping and taking defect data for 20 working days during October 2020. In its implementation, it has succeeded in reducing the defect of product from 4,556 DPMO to 2,047 or increasing the sigma level of the company from 4.10 to 4.38.

Vehicle type approval (VTA) total registration of electronic vehicles in Indonesia for the accumulation period until August 2023 is 81,525 units with a composition of 4-wheeled vehicles 18,300 units. The use of electric vehicles is still a tiny portion compared to the motorized vehicle population in Indonesia, which will reach more than 146 million units in 2022. It is different from developments in Europe, the United States, and China, where more research into the use of electric vehicles is being carried out. The readiness of the automotive industry system to produce electric vehicles is absolutely necessary to achieve superior productivity levels. National automotive companies need to anticipate that changes in production systems will also change along with changes in processes and components in electric vehicles. In the next few years, world-class manufacturing production systems will refer to LARG (lean, agile, resilient, and green) aspects. Lean, agile, resilient, and environmentally friendly manufacturing industrial operations are critical. This research aims to determine the level of application of LARG aspects in the electric vehicle automotive industry. The method used was exploratory, and a questionnaire was filled out with industry experts and analyzed using the analytical hierarchy process (AHP) and objective matrix (OMAX). The results of this study confirm that all aspects of LARG require improvement. Resilience (R) and green (G) have performance below 10 percent, so these two aspects are priorities for improvement by the electric car industry in Indonesia.
