Abstract

Terdapat beberapa fitness center di Surabaya yang membuat persaingan bisnis fitness center bertambah ketat. Oleh sebab itu fitness center harus mempunyai perbedaan dan keunggulan, yang membuatnya berbeda dari yang lain. Untuk bisa memberikan perbedaan, maka fitness center harus tahu dan menentukan jenis konsumen yang dilayani. Penelitian ini menganalisa segmentasi konsumen fitness center berdasarkan variabel-variabel yang mendasari proses pemilihan suatu fitness center (Purchasing), gaya hidup (Life Style) dan motivasi (Motive), serta keterlibatan (Involvement). Dilakukan analisa faktor untuk mereduksi dan mengelompokkan variabel menjadi 15 faktor yang mempunyai kemiripan, dan berdasarkan 15 faktor tersebut dilakukan analisa cluster untuk membagi responden. Analisa crosstab digunakan untuk mengetahui perbedaan profil responden antara cluster dan didapatkan bahwa ada perbedaan variabel pendidikan terakhir dan jenis pekerjaan pada 4 cluster yang terbentuk. Dengan demikian, dihasilkan 4 cluster/segmentasi yaitu: cluster ”kenyamanan”, cluster ”sensitivitas rendah”, cluster ”individual”, dan cluster ”kesenangan”. Dari informasi tersebut pengelola fitness center dapat menentukan target konsumen yang akan dilayani dan bagaimana pengelolaan fitness center.Keywords: Segmentasi, Psikografis, Behavioral, Cluster, Fitness Center

Abstract

Musculoskeletal Disorders (MSDs) caused by computer use have become the most common ergonomic risks. The risk experienced can be in the form of financial losses or even lives. Therefore, efforts are needed to prevent the occurrence of ergonomic risks so as not to cause large losses. The Rapid Office Strain Assessment (ROSA) has been designed to identify ergonomic risk factors and is reliable for the assessment of office workers' MSDs. This study evaluates the potential risk of ergonomics in female office workers because a previous study found that MSDs were more common in women. From the two workers observed, it was found that workers 1 and 2 received different scores on several assessment components. The different things are the length of the seat holder, armrests, spine brace, and keyboard. This difference is caused by body posture and different types of chairs. The length of the chair and the spinal brace is influenced by the different postures of the two workers. Worker 1 has a shorter upper leg length than worker 2, so she cannot use the backbone section of the chair. Although there are differences in scores on some components of the assessment, both workers have the same final ROSA score, which is 5. This indicates that further posture assessment needs to be done using tools other than ROSA to detect the specific cause of MSDs levels.

Abstract

5S method as lean concept foundation is an effective tool to achieve improvement effort in organizations. Organizations which do not have working area standard yet according to 5S method have the chance doing the improvement, as the design suggested to the publishing and bookstore chain company. The research was done in three working areas processing product ordering documents by consumers. Data collection was done by field observation and interviews to related staff. Data collected includes process flow in the three working areas, actual physical working area condition, and activity time as modeling base with ProModel 2001. Based on review related to methods, machines, environment, materials and man aspects, the three working areas need an improvement based on 5S method. The company does not have similar standards yet, so kinds of waste happen at times at the working areas. Gudang working area improvement was done based on waste identification, process flow, activity time, and current actual physical condition. At departemen administrasi, the improvement was done based on waste identification, actual physical condition, and the area necessity. At departemen keuangan, improvement was done based on waste identification, actual physical condition, and the area necessity. At the three working areas the 5S was designed from seiri (proper arrangement), seiton (orderliness), seiso (cleanliness), seiketsu (standardize), and shitsuke (discipline) activities each. Gudang working area modeling was done with the basis on activity time data to test improvement design effect according to 5S method. Modeling was based on actual condition and three alternatives.Working area improvement design with 5S method was designed as suggestions at the three working areas in the company. Success factor in the implementation is viewed based on the whole staff’s commitment, with the consideration on any obstacles, such as workers’ resistance to the 5S method suggested. Therefore, in this research workers’ psychology aspects could be taken into consideration for further details. Modeling results indicated the alternative to eliminate a certain single activity without any staff added yielded the optimum result and could be taken into consideration for the company to implement.Keywords: 5S, Lean, Waste

Abstract

PT. Garuda Metalindo, which is engaged in the manufacturing industry, is currently experiencing a product failure of 2.5% in the production process and this exceeds the failure tolerance set by the company, which amounts to 10 units of 1000 units per process function or about 1% in the production process. Failure tolerance that exceeds the limit so that improvements need to be made to reduce the number of product defects in each production process. This study uses Fault Tree Analysis (FTA) to identify the causes of product defects based on the current production process, the next stage using Failure Mode and Effect Analysis (FMEA) to identify potential failures, modes, potential effects of failure, causes of failure, detection modes, and determine the rating against severity, occurrence, and detection on the risk priority number in the production process. Based on the results of the assessment on the RPN, a cold forming process with a score of 576, surface finishing with a score of 512 was obtained, machining 1 with a score of 441, and machining 2 with a score of 392. Proposed improvements for cold forming defects by monitoring and making checking tools (jigs), defect surface finishing by supervising and making product shelves, machining defects 1 with product inspection and making tools for checking (jig), and replacement of drill bit types, machining defects 2 with lamp and insert replacement and periodic inspection. By applying these proposals it is expected to reduce the level of product disability.

Abstract

This study was carried out to characterize the formation of crystoballite crystall of silica extracted from rice husk by sintering. Extraction of silica using 5% KOH and 10% HCl solution was sintered at 750, 900, 1000,and 1100 C. The products were characterised in term of functional groups, microstructure and structure (FTIR, SEM and XRD). Characterisation of the silica using FTIR shows the presence of silanol and siloxane. XRD results confirmed that silica amorph was formed at 750C, through the intermediate formation of crystoballite 900, 1000, and 1100C. The formation of crystoballite structure increases with increasing temperature of sintering, which confirms the presence of regular particle size using SEM analysis.Keywords: Rice Husk, Silica, Crystoballite, FTIR, SEM and XRD
