Abstract

Small and medium enterprises (SMEs) often struggle with implementing effective quality management practices, especially in traditional industries like batik production. These challenges include ensuring consistent product quality to differentiate from competitors and attract customers. This study focuses on addressing quality control issues in small-scale Batik Tanah Liek production, where significant defects persist. The research aims to assess existing practices, identify defect causes, and propose solutions to enhance product quality and reduce rejection rates. These efforts contribute to improving production efficiency and supporting the sustainability of this traditional craft. The study employs a systematic approach combining quality management methodologies, including data collection, problem identification, brainstorming, the Failure Mode and Effects Analysis (FMEA) approach, and actionable recommendations. Data was gathered through a questionnaire to capture perspectives on defects and quality control issues in batik production. Key quality challenges identified include faded batik, torn fabric, and incorrect motifs. Analysis revealed that the primary cause of incorrect motifs is the malfunctioning canting tool, which hinders proper wax application. Additionally, defects in dyeing and boiling processes contribute to fabric fading and tearing, exacerbating quality issues. The findings underscore the need for systematic solutions, such as creating clear work instructions, designing Standard Operating Procedures (SOPs) for process consistency, and implementing preventive maintenance schedules for equipment. By addressing these issues, the study provides practical interventions to improve production quality. These measures not only enhance the economic viability of SMEs but also play a crucial role in preserving the cultural heritage of Batik Tanah Liek. The implications of this research highlight the potential for broader adoption of quality management practices in traditional industries to ensure their sustainability in competitive markets.

Abstract

The growth of the Wastes from Electric and Electronic Equipments (WEEEs) or e-waste is presently considered to be one of the rapid increasing wastes streams in the large city of Indonesia. Concurrently, the urban mining activities for e-waste by informal sectors have potential on the economic, social and environment dimension. The three dimensions form a triple bottom line that supports the principles of sustainability in the manufacturing. In this research, the observation in some remote areas in Padang is conducted to find out the model of e-waste collection system activities from the household and its economic potential, especially for refrigerators e-waste. The result shows that minimaly there are three models of the e-waste collecting system for refrigerator e-wastes. The model involves all the parties in urban mining activities such as e-waste collectorsfrom household, repair shops, collectors who continue the re-assembly and classify the e-waste and final collectors who did the cleaning, crushing, packing and transporting e-waste to another city to do the recycling process. In this e-waste collecting model the components of refrigerator e-waste could be reused, remanufactured and recycled. From the reassembly of therefrigerators it is obtained the material composition of 58.1% iron, 26.3% plastic,10.9% styrofoam 10.9%, 2.1% aluminum, 1.8% copper pipe, and 0.8% others. The highest cumulative retained value is obtained from this collecting system ranged between IDR 230.200 to 355.200, where some second-hand components may still be inreuse and remanufacture. This price is equivalent to 14.9% to 22.1% the purchase price of a new refrigerator.

Abstract

Karya tulis ini berkenaan dengan pengembangan perangkat lunak berbasiskan Web untuk perhitungan waktu kerja standar yang merupakan sebuah modul tambahan pada aplikasi perangkat lunak untuk perancangan sistem kerja berbasiskan Web atau yang diberi nama @WebPlan® yang sudah dikembangkan oleh penulis. @WebPlan ini merupakan integrasi dari beberapa modul untuk perancangan tataletak dan disain stasiun kerja secara virtual 3D. Beberapa modul sudah dirancang sebelumnya yaitu modul untuk visualisasi produk dan strukturnya sehingga dimungkinkan visualisasi yang interaktif untuk proses perakitannya. Sedangkan modul utama dalam @WebPlan ini adalah 3D Facilities Layout dan disain/layout stasiun kerja. Untuk tujuan ini juga sudah dibuat beberapa alat bantu yaitu model manusia 3D untuk beberapa persentil dan beberapa analisa dan checklist ergonomi. Pengembangan aplikasi @WebPlan ini untuk perhitungan waktu standar pada produksi serial merupakan suatu yang sangat diperlukan untuk menentukan waktu total yang diperlukan dalam memproduksi/merakit sebuah produk. Waktu total ini merupakan data penting dalam membuat konfigurasi stasiun kerja untuk pembuatan produk. Metoda Pengukuran waktu perakitan yang dipakai dalam hal ini adalah MTM-UAS (Universal Analysing System) yang sangat cocok untuk perakitan manual. Hasil perhitungan waktu proses perakitan ini divalidasi dengan proses perakitan yang sebenarnya dan tidak menunjukkan perbedaan harga yang cukup signifikan. Beberapa kemudahan yang didapat pada metoda ini adalah MTM-UAS menggabungkan beberapa gerakan dan tidak terlalu detail dibandingkan metoda pengukuran waktu lainnya. Akan tetapi memiliki hasil yang cukup mendekati hasil yang sebenarnya. Modul aplikasi perhitungan waktu standar ini merupakan bagian yang diintergrasikan nantinya dalam perancangan tataletak dan stasiun kerja secara virtual 3D

Abstract

Cloud Manufacturing is an advanced manufacturing model which provides services by utilizing a shared resource pool such as computers, servers, networking, Internet and application softwares. The term Cloud Manufacturing in the engineering literature is still fairly new. it comes from the term Cloud Computing which is earlier known as Internet services on demand. Here includes Software as a Service (SaaS) along with infrastructure, platform and other delieveries as a service. First introduced by F. Tao in 2011, Cloud Manufacturing combines the latest technologies such as cloud computing, internet of thing, manufacturing object virtualizations and service-oriented computing services. The advanced manufacturing service models related to this terminology will be described as literatur reviews in this paper. At the end of this paper was given a case study of the application of the Cloud Manufacturing for designing a web-based production facilities layout as a cloud software as a service for the users.

Abstract

This paper is concerned with the measurement of customer satisfaction a motorcycle repair shop in the city of Padang on the quality of service received by the SERVQUAL method. The method was developed in the 1980s by Zeithaml, Parasuraman & Berry used a questionnaire to measure quality of service. With this, it is known how big the gap (gap) that exists between perceptions and expectations of customers of a service company. Method of quantitatively measuring the quality of this service, contains dimensions such as tangibles (physical facilities and personnel), responsiveness (responsiveness), realibility (reliability), assurance (security) and empathy (empathy). The purpose of the use of the SERVQUAL dimensions is to make program improvements in the control of service-oriented to customer satisfaction, as one of the company's strategy to empower Total Quality Service. From the analysis of 84 samples without weighting the data of interest can be concluded that there is a gap between perception with expectations in every dimension. The sequence starts from the dimensions of each dimension with the largest gap is tangible dimension, followed by the dimensions of assurance, reliability, empathy and responsiveness of the last dimension. The average total gap of each dimension is equal to -0.8664. This suggests that the quality of service expected by customers has not been achieved. From the analysis of the value obtained by the dimensional weight of the interests of tangible (physical facilities and personnel) should get the greatest attention to be fixed.
