Abstract

Selection of Third Party Logistics (3PL) services is an important focus of attention for companies in selecting suppliers in their supply chain. The wide marketing area of PT PETRONAS's lubricant products demands 3PL performance to increase the company's service level. The purpose of this study is to analyze the decision-making process in the context of selecting 3PL transportation suppliers using the TOPSIS and PROMETHE multi-criteria methods. The type of data used consists of primary data and secondary data through library research, interviews, and field surveys. The process of selecting a transportation 3PL is carried out in two stages, namely selection of criteria and the commercial aspect of the bidding price per region is evaluated as the basis for selecting the best supplier. The selected suppliers are PT Wira Logitama Saksama, PT Glory sogotrans Mandiri, PT Iron Bird Logistik, PT Sumisho Global Logistik, and PT Dunia Express Transindo. Based on the results of the analysis using the PROMETHEE method, five criteria with the highest weight were produced, namely Price, Time Delivery, Health Safety Management, Infrastructure and Office Equipment. The results of the ranking using the TOPSIS method for shipping to each destination are that PT Wira Logitama Semesta is the best supplier for five shipping destinations, namely Jabodetabek, Bandung, Surabaya, Lampung and Medan and PT Iron Bird Logistik is the best supplier for shipping to Cilegon and Semarang.

Abstract

Product and service quality factors are important aspects of business continuity. Consumers will abandon low-quality products and services. Consumers will feel satisfied if all aspects of the products and services are appropriately accommodated. Product and service quality have different tendencies because service quality dimensions are more complex than product quality. This study aims to analyze the quality of customer service at auto repair shops based on consumer preferences. Assessment of the level of satisfaction and consumer expectations of each attribute is done by filling out a questionnaire to identify the gap between the level of importance and level of performance. The consumer's assessment of each indicator of the auto repair shop is carried out through a questionnaire filled out to the consumer to find out the gap between the level of importance and the level of performance. The analytical method used is Importance Performance Analysis–IPA showing that the attributes of auto repair shops that need to be improved are [P1] improving the repair period as promised, [P2] Procedures and managerial capabilities in providing adequate service, [P3] Results following consumer recommendations, and [P4] Knowledgeable workshop managers and staff, [P5] Service speed from responsiveness quality dimensions, [P11] Credibility and honesty of workshop managers and staff, [P12] Clarity of communication and information to consumers. The priority of quality attributes of auto repair shops that will be improved can provide alternative development priorities between human resources and limited equipment servicing.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Aircraft maintenance in remote locations is a prevalent challenge for local airlines in Indonesia, leading to diminished productivity and efficiency in the maintenance division. This issue is substantiated by a significant incidence rate of 36% annually, as reported by a national airline. The current solution needed is the improvement of the Maintenance System to eliminate off-hangar maintenance for Narrow Body aircraft in the national aviation service industry. This study aims to identify the causal factors of aircraft requiring maintenance when located outside the primary maintenance facilities and to reduce these occurrences. The Reliability Centered Maintenance (RCM) method is employed to determine the most effective maintenance approach based on system and equipment reliability, and the fuzzy logic method in FMEA is utilized to address ambiguity and uncertainty in risk assessment. Primary data were obtained from Focus Group Discussions (FGD) with experts working in the airline industry. Secondary data were collected from all aircraft experiencing breakdowns outside the main hangar. The findings reveal that the primary factor for maintenance outside the main facilities is the current maintenance policy of Finding Failure (FF), which leads to unpredictable maintenance activities, resulting in damage outside the main facility areas (Batam, Cengkareng, and Surabaya). Incidents of maintenance outside the main facilities can be eliminated by shifting the policy to Time Directed (TD), enabling the company to reduce costs from an initial IDR 342,681,011,118.60 to IDR 70,370,514,198.60, achieving a cost saving of 79.47%.

Abstract

Kegiatan perawatan dan pemeliharaan merupakan salah satu penyebab terjadinya keterlambatan jadwal penerbangan suatu maskapai. Berdasarkan laporan dari salah satu maskapai penerbangan nasional terdapat 39% pekerjaan maintenance tidak dapat terselesaikan pada periode Januari 2022 - Juni 2023. Peningkatan produktivitas maintenance diperlukan agar dapat meningkatkan jumlah pekerjaan selesai dan memperkecil kontibusinya terhadap keterlambatan. Penelitian ini bertujuan untuk meningkatkan produktivitas pada divisi maintenance. Penelitian ini menggunakan metode Overall Equipment Effectiveness (OEE) untuk mengetahui nilai perbaikan sebelum dan sesudah dilakukan perbaikan, metode Maintenance Value Stream Maping (MVSM) untuk membuat peta aliran proses kegiatan  maintenance sehingga dapat mengetahui penyebab efektivitas dan efisiensi yang tidak tercapai dengan metode fishbone diagram. Penelitian ini mengungkapkan bahwa efisiensi keseluruhan peralatan (OEE) yang pada awalnya hanya 29,38% sebelum dilakukannya perbaikan dapat meningkat secara signifikan mencapai nilai 54,49% pada akhir perbaikan. Setelah melakukan pemetaan proses dengan Current MVSM didapatkan nilai sebesar 38,70% yang disebabkan oleh faktor -faktor utama yang berkontribusi pada rendahnya efektivitas dan efisiensi termasuk kekurangan dalam keterampilan, pengalaman, dan motivasi tim, hambatan dalam komunikasi dan strategi perencanaan, kurangnya pemeriksaan terhadap peralatan dan penggunaan alat yang tidak efektif, manajemen persediaan sparepart yang tidak memadai, serta lingkungan kerja yang kurang mendukung. Melalui simulasi yang melibatkan sebuah tim kecil yang dikondisikan secara ideal, nilai Value Added dari pemetaan Future MVSM meningkat menjadi 45,54%.

Abstract

The industrial sector is the backbone of the country in building the defense sector and economic stability that needs to maintain productivity and be competitive. One of the companies that manufacture automotive components, Mitsubishi, manufactures automotive components and must have zero defect requirements. However, in practice, it was found that 1 (one) unit of CJM had a brake caliper malfunction in the condition that the unit was ready to be sent to the carpool consumer of a company that produces automotive components. The damage is a discrepancy in the diameter of the piston seal, which closes the gap between the piston and the piston housing, allowing for brake fluid leakage, which affects the "zero defect" commitment. Through the application of the Root Cause Corrective Action (RCCA) method with the formation of a Root Cause Investigation (RCI) team, an investigation was carried out to find the root cause of the failure. However, the data processing results of the diameter of the seal thickness obtained have a Cp value of 0.98 and a Cpk of 0.81, which means the process has not been able to work optimally. Therefore, we decided to make some improvements, adding Standard Operating Procedures (SOP), Work Instructions (WI), and making Poka-Yokes as corrective actions in dealing with this problem. After almost 3 months since the investigation began, the data processing results on the piston seal were Cp = 1.86 and Cpk = 1.80.

Abstract

Peralatan industri yang ideal adalah ketika semua semua perlengkapan yang dibutuhkan dapat berfungsi dengan baik. Salah satu indikator efektifitas mesin dan peralatan adalah mengetahui nilai OEE (Overall Equipment Effectiveness). Nilai OEE merupakan akumulasi dari nilai-nilai Availability, Performance, dan Quality. Tujuan kegiatan Pengabdian Kepada Masyarakat ini adalah untuk mengedukasi industri dalam menghitung dan menganalisis nilai OEE nya sehingga mempunyai gambaran seberapa besar capaian efektivitas mesin dan peralatannya. Digunakan beberapa metode pelatihan, yaitu: metode ceramah, metode tanya jawab, dan metode simulasi perhitungan nilai OEE dengan data-data internal perusahaan. Perhitungan nilai OEE secara rutin umumnya jarang dilakukan, padahal ini penting agar semua pihak terkait dapat mengetahui level capaian OEE dan berupaya meningkatkannya. Data-data basis perhitungan nilai OEE harus dilakukan secara benar, agar angka atau nilai OEE hasil perhitungan mencerminkan capaian ril yang sesungguhnya. Kondisi OEE yang ideal (85%) mungkin akan sulit dicapai, namun dengan perbaikan nilai OEE secara berkesinambungan akan bermanfaat bagi peningkatan daya saing perusahaan di masa yang akan datang.
