Abstract

The research aimed to improve the quality problem from the previous plant that contributed to the Rate of Quality (RQ) and Overall Equipment Effectiveness (OEE) value in Cylinder Block Machining (CBM). The research was done in one of an automotive company in Indonesia. It had been applying Total Productive Maintenance (TPM) with Kaizen spirit to make continuous improvement even though this company had reached a world-class level on the Japan Institute of Plant Maintenance (JIPM) standard. To express the needs and wants of the current machining plant and improve quality problems from the previous process in the casting plant, the researchers used Quality Function Deployment (QFD) method. From the result, it is known that shrinkage defect at a casting product becomes the priority of the kaizen team to achieve next process customer satisfaction in a machining plant to increase the RQ and OEE value. By implementing improvement based on the highest value of Technical Priorities (TP) from House of Quality (HOQ), it can increase RQ value in CBM from 96,4% in December 2018 to 97,9% in February 2019. Then, OEE value increases from 92% to 93% within two months.

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.

Abstract

Proses curing pada industri manufaktur ban merupakan tahap kritis dengan konsumsi energi tinggi yang berkontribusi signifikan terhadap emisi karbon dan biaya produksi. Penelitian ini bertujuan untuk mengidentifikasi penyebab utama downtime mesin curing dan mengembangkan strategi perbaikan berbasis Total Productive Maintenance (TPM) dan Root Cause Failure Analysis (RCFA). Data dikumpulkan dari 240 unit mesin curing selama periode Januari–Juni 2025, mencakup durasi downtime dan konsumsi energi dalam kondisi idle. Hasil analisis menunjukkan bahwa implementasi perbaikan seperti autonomus maintenance, pemasangan andon system, dan pelatihan operator mampu menurunkan downtime hingga 45% dalam tiga bulan. Dampaknya, konsumsi energi idle turun signifikan, menghasilkan penghematan energi sebesar ±76 juta kWh listrik, ±152 juta kg steam, dan ±24 juta Nm³ nitrogen.  Hal ini setara dengan pengurangan emisi sebesar ±84.912 ton CO₂ dan efisiensi biaya mencapai Rp 181,8 miliar dalam tiga bulan operasional. Jika diekstrapolasi secara tahunan, penghematan ini berpotensi mencapai ±Rp 727 miliar atau sekitar 18% dari total biaya operasional tahunan proses curing. Penelitian ini memberikan bukti bahwa pendekatan TPM dan RCFA tidak hanya meningkatkan keandalan mesin, tetapi juga mendukung transformasi industri menuju energi rendah emisi.

Abstract

Distribusi produk pertanian, khususnya buah-buahan yang mudah rusak, memegang peranan vital dalam menjaga kualitas produk dan efisiensi logistik. Keterlambatan pengiriman menjadi masalah utama dalam distribusi buah di Provinsi Jawa Barat, dengan tingkat keterlambatan mencapai 15–20% dan tingkat kerusakan produk 10–15%. Penelitian ini bertujuan untuk membandingkan efektivitas dua metode optimasi rute distribusi, yaitu metode Saving Matrix dan Algoritma Genetika, dalam konteks pengiriman buah dari berbagai wilayah di Jawa Barat menuju Bandung. Penelitian ini mengintegrasikan parameter degradasi kualitas buah berdasarkan waktu pengiriman dan karakteristik komoditas, seperti masa simpan. Pendekatan mixed-method eksplanatori sekuensial digunakan dalam penelitian ini. Tahap kualitatif dilakukan melalui wawancara dan observasi terhadap delapan stakeholder industri logistik pertanian. Temuan kualitatif menjadi dasar perancangan model optimasi. Pada tahap kuantitatif, Saving Matrix dan Algoritma Genetika diimplementasikan menggunakan bahasa pemrograman Python dengan library seperti geopy, DEAP, dan matplotlib. Data jarak antar titik diperoleh dari koordinat geografis, dan model optimasi dikembangkan berdasarkan formulasi Vehicle Routing Problem (VRP) yang disesuaikan. Hasil penelitian menunjukkan bahwa Algoritma Genetika lebih unggul dalam konteks kompleksitas tinggi, dengan kemampuan mengurangi waktu pengiriman hingga 22% dan penurunan kerusakan stroberi dari 15% menjadi 7%. Sementara itu, Saving Matrix lebih unggul dari sisi kecepatan komputasi dan efisiensi awal, namun kurang adaptif terhadap variasi karakteristik produk dan medan geografis. Penelitian ini memberikan kontribusi pada praktik logistik pertanian dengan menawarkan solusi berbasis algoritma untuk distribusi buah yang lebih efisien dan adaptif terhadap kondisi riil. Hasil ini juga memperkaya literatur tentang penerapan heuristik dan evolusioner dalam konteks distribusi produk perishable di negara berkembang seperti Indonesia.

Abstract

Developing new products based on sustainable product development is not easy. It is necessary to consider various aspects such as price, quality, consumers, competitors, and others. Large-scale companies have the resource capacity to develop new products. However, for small and medium enterprises (SMEs) with limited capital and equipment, developing new products that are successful in the market response is a complicated job. This community service activity aims to educate SMEs about sustainable new product development and the basic procedures for developing a new product. It is carried out in collaboration with partners from PERMAI Penang, targeting Indonesian workers in Malaysia who may be trying to develop independent businesses. Specifically, this training will help participants 1) Identify the type of product to be developed, 2) Understand all aspects related to new product development, 3) Understand the standard stages of product development. By increasing the knowledge of independent entrepreneurship among workers in Pulau Pineng Malaysia, we hope that more SMEs will succeed in developing products or services for consumers. Empowering employees to prioritize their welfare by knowing the basics of new product development will create additional income for migrant workers who take part in this training.Contribution to Sustainable Development Goals (SDGs):SDG 9: Industrial Innovation & Responsible ProductionSDG 12: Sustainable Production & ConsumptionSDG 11: Sustainable Cities and CommunitiesSDG 17: Partnership for Sustainability

Abstract

This study aims to implement the Six Sigma method on formal men's jacket products in the garment industry to increase the level of sigma. The methodology is based on the Define, Measure, Analyze, Improve, and Control (DMAIC) approach. The new approach in this study is the determination of 5W+1H using a Focus Group Discussion (FGD) with five expert judgments. The design of this study has applied the Six Sigma method at the Measure stage. It is a measurement before improvement and after the Control stage as a measurement after improvement. The results of this study have increased the level of sigma from 3.5765 to 3.7839, so there is an increase of 5.48%. Increasing the sigma level contributes to a decrease in defects at the finish line by 44.09% every month. Implementing the Six Sigma method to the DMAIC approach has succeeded in increasing the level of sigma, automatically reducing the percentage of defects and increasing the productivity of formal men's jackets in the garment industry.
