Abstract

According to preliminary research conducted at Balai Besar Keramik, it is found out that “Batako Padalarang” products  available in the market are still below the Indonesian National Standard requirement (SNI 03.2113.91). This research  is conducted to obtain optimum process parameters to meet  the  requirements of Indonesian National Standard. The method  used is Taguchi Parameter Design to fulfill the criteria for compression strength of Indonesian National Standard. From the analysis of Taguchi method, we get to know that the factors and level that affect the batako’s strength of compressive significantly are factor A (forming pressure) with level 2 (4  ton),  factor B (material composition) with level 1 (1 : 3), factor C (texture of tras) with level 1 (0,3 mm), factor D (mixing time) with level 2 (10 minutes), factor E (water percentage) with level 2 (15%), and factor F (curing time)  with level 3 (28 days). And from the confirmation experiment we get percentage of increase after using Taguchi method amounting to 72.75% and the decrease of loss 92.82%. Keywords : Taguchi, batako, loss fuction

Abstract

PT X is a spinning company which produces sewing thread. The company has some quality problems at twisting area, where defects are detected. To improve the quality performance in that area, DMAIC method is used . The result of the study and analysis reveals that the first priority of defect that has to be fixed is curly thread, then hairy thread, and last is the thread that has abnormal TPI. The research suggests some improvement proposals: the use of ultraviolet light sensor forthread, installation of automatic system at some parts of the machine, cooperation with raw thread suppliers and/or spare-part machine suppliers to look for solutions by collaborating with SISIR, the possibility of finding alternative suppliers, the use of the original spare parts, some training andmentoring how to maintain the machine for relevant staff and technicians , utilization of check-sheet form in work inspection which is to be filled, completed by operators and to be checked by chief operator, and the use of picture image of assembly thread line as a guide for operators.Keywords: Thread Defect, Quality, DMAIC, 5W+1H

Abstract

This applied research is done at Seteran Semarang Restaurant in Bandung as a business development model by opening a new branch at Paskal Hyper Square Bandung. The variables used for the service qualities of what consumers want are variables derived from 5 main dimensions according to Parasuraman V. A Zeithaml and L.L Berry. Those five main dimensions are tangibles, reliability, responsiveness, assurance, and empathy. The result of QFD part 1 shows that there are 35consumer needs, which are arranged according to priority scale as proposed by the previous 5 main dimensions and there are 43 technical efforts needed to meet these consumer needs. The 43 technical efforts require 47 design characteristics which are shown in QFD part 2 and to be further deployed to part 3. The third part of QFD produces 68 characterictics of process which must be done in order to fulfill the 47 design characterictics in the second part. The goal of this research is to design servicedevelopment model by deploying from consumer needs into the process characteristics according to the priority scale.Keywords: QFD ( Quality Function Development ), Service Quality.

Abstract

Ho Kie San Noodle Factory is one of the MSMEs in Patikraja District, Central Java that produces traditional noodles. Previously, the community service team had assisted this partner in increasing its production potential. However, there are still many improvements that can be made. The management conveyed the need for Kaizen (continuous improvement) material. Therefore, community service activities were carried out again in this factory. The method used is training. There were 9 participants who attended, representing the human resource department, finance department, general department, administration department, technical department, production department, inventory department and marketing department. The stages of the activities carried out were factory surveys and interviews with management, training implementation preparation, compiling training materials, filling preliminary questionnaires, training to representatives of each department within the company regarding the concept of continuous improvement and streamlined, and filling evaluation questionnaires. Based on the results of the questionnaire, it was found that the level of understanding of the participants increased after the training. Providing materials of Kaizen (continuous improvement) as well as production flow streamlining can help participants in streamlining the flow in each department and can also give motivation to continue making improvements in each department.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) berperan dalam menciptakan lapangan kerja dan mendorong pertumbuhan ekonomi. Sebuah Perguruan Tinggi melalui kegiatan Pengabdian kepada Masyarakat (PkM) dapat mendukung peran UMKM tersebut. Pido’a Sepuh Collection, berlokasi di Bandung, merupakan UMKM yang bergerak dalam bidang pembuatan boneka dengan beragam jenis dan ukuran. Program Sarjana Teknik Industri bermaksud membantu UMKM ini dalam merancang fasilitas produksi dan penataan stasiun kerja agar kapasitas produksi setiap stasiun kerja dapat ditingkatkan dan pekerja dapat bekerja dengan nyaman. PkM dilakukan dalam empat tahapan utama yaitu tahapan kunjungan dan wawancara, dilanjutkan dengan tahapan survei lapangan untuk pengamatan dan pengumpulan data. Tahapan ketiga adalah perancangan fasilitas produksi dan usulan penataan stasiun kerja, dan tahapan terakhir adalah penerapan usulan dengan harapan terjadi peningkatan kapasitas produksi dan pembukaan lapangan kerja baru untuk masyarakat sekitar. Penataan stasiun kerja yang dilakukan dan perancangan fasilitas produksi yang diusulkan dapat meningkatkan kenyamanan operator dalam bekerja, karena stasiun kerja tertata lebih rapi. Selain itu, kapasitas produksi meningkat sebesar 21,43% untuk stasiun penggambaran dan pemotongan pola, 10,71% untuk stasiun penjahitan dan 22,38% untuk stasiun penjahitan mulut boneka.
