Publisher : Universitas Katolik Parahyangan

PT X merupakan perusahaan yang memproduksi paint bucket (ember cat) yang terdiri dari tiga jenis paint bucket, yaitu bucket polos, lid (tutup bucket) dan bucket berlabel. Persentase bucket polos cacat sebesar 1,95%, persentase lid cacat sebesar 0,65% dan persentase bucket berlabel cacat sebesar 6,28%. Peningkatan kualitas paint bucket dilakukan dengan menggunakan metode Six Sigma DMAIC. Pada tahap D (Define) dilakukan pembuatan deskripsi proses produksi, pembuatandiagram SIPOC dan penentuan critical to quality (CTQ). CTQ untuk bucket polos dan lid diperoleh sebanyak dua buah, sedangkan CTQ untuk bucket berlambel sebanyak delapan buah. Pada tahap M (Measure) dilakukan pengukuran performansi sebelum perbaikan berupa rata-rata DPMO.Rata-rata DPMO bucket polos, lid dan bucket berlabel berturut-turut sebesar 7.591,88, 3.420,77 dan 8.109,44. Pada tahap A (Analyze) dilakukan penentuan prioritas perbaikan CTQ dengan membuat diagram Pareto dan mencari penyebab terjadinya cacat pada bucket polos, lid dan bucket berlabel. Berdasarkan diagram Pareto, penelitian fokus memperbaiki 1 jenis cacat pada bucket polos dan lid, yaitu cacat susut dan 5 cacat pada bucket berlabel, yaitu perbedaan tinggi pada pertemuan foil, foil terkelupas, foil hanya menempel sebagian, penempelan tidak menghasilkan pertemuan foil dan bintik putih. Setelah diketahui penyebab terjadinya jenis cacat, dilakukan tahap I (Improve).Tindakan perbaikan yang dilakukan adalah penggunaan infrared thermometer, pembuatan alat bantu, penggunaan microfiber gloves, pembersihan jalur keluar bucket polos, dan lain-lain. Setelahdilakukan perbaikan, dilakukan tahap C (Control). Tindakan perbaikan mengakibatkan terjadinya penurunan nilai rata-rata DPMO pada bucket polos, lid dan bucket berlabel, yaitu berturut-turut sebesar 2.621,54, 1.169, dan 713,69.

Kue balok merupakan makanan ringan tradisional yang saat ini menjadi kegemaran bagi masyarakat kota Bandung. Semakin tinggi permintaan konsumen terhadap kue balok, akan mengakibatkan produsen kue balok semakin sering berinteraksi terhadap alat cetak kue balok. Namun ternyata alat cetak kue balok yang digunakan oleh produsen kue balok saat ini merupakan alat cetak kue balok yang belum mempertimbangkan aspek ergonomis ENASE (Efektif, Nyaman, Aman, Sehat, dan Efisien). Beberapa masalah yang dialami oleh produsen kue balok saat menggunakan alat cetak kue balok saat ini, diantaranya: pinggang dan punggung sakit karena terlalu sering membungkuk, panas yang berasal dari arang sebagai bahan bakar alat cetak kue balok langsung memapar tubuh produsen, tidak adanya bahan isolator pada pegangan alat cetak kue balok, dll. Masalah ini akan berisiko terhadap keselamatan para produsen alat cetak kue balok, bila semakin sering berinteraksi dengan alat cetak kue balok saat ini tersebut. Jika semakin sering produsen kue balok berinteraksi, maka akan semakin tinggi pula kemungkinan masalah-masalah tersebut dirasakan oleh produsen. Oleh sebab itu dalam penelitian ini dilakukan perancangan alat cetak kue balok dengan menggunakan metode EFD (Ergonomic Function Deployment). Dalam metode ini perancangan produk dilakukan dengan mempertimbangkan aspek-aspek ergonomis ENASE

The purpose of this study is Â to evaluate the effect of shift work on level of fatigue and Â performance of railway controller. Seventeen participants are the railway controller of Bandung Station. Fatigue was measured using subjective questionaire Swedish Occupational Fatigue Inventory (SOFI) and performance was measured using Psychomotor Vigilance Task based on reaction time.Â Friedman test and Bonferonni-Dunn test were used to process data. Statistical analysis indicates there was significant difference level of fatigue and human performance between shift work. Fatigue occurs at sleepiness, phsysical discomfort and lack of motivation dimensions, while performance occurs at mean 1/RT, fastest 1/RT and slowest 1/RT (P < 0,10). %. The highest fatigue and the worst performance occurs after night shift. After night shift, the level of fatigue increased about 37% to 162%, meanwhile performance were decreased about 3% to 11%. Although there were significant difference of level fatigue, the average scores are below 1 (score 0-7). This result indicates that the fatigue of controllers Â are very low.Â Although maybe is not really necessary to redesign shift work system, but working hours on each shift still need to be concerned.Â

Computer games, especially First Person Shooter (FPS) have become one of the fastest growing and most economically sucessful software in Indonesia. Given the potential economic benefits of the FPS games, it is important to design its user interface as usable as possible to win the market. In accordance, it is crucial to find out what user interface factors should be considered in designing an FPS game. These factors can be used as a designing guide for game developers in Indonesia. The purpose of this paper is to discover the main user interface factors that should be considered in designing an FPS game especially from usability point of view and to suggest improvement of the user interface in current FPS game.Fourty (40) usabilty attributes from literature review are qualitatively grouped into 5 factors. Those factors are: Basic FPS Feature (BFF), Basic Game Feature (BGF), Display & Sounds (D&S), Help & Hints (H&H), and Enjoyment (E). Usability testing on the factors is conducted in three different groups of players: Novice, Experienced, and Expert. Mann-Withney Test are conducted to understand performance difference for each group. The result shows that BGF and H&H are not significantly difference for all groups. While for BFF, the novice group tend to have different preference rather than other groups since there is not enough time duration given on novice users accessing the FPS feature. For D&S, expert tend to have different preference rather than other groups. Some future research potentials are also proposed in this paper.

Lighting is one of the human basic needs that must be fullfiled. Compact fluorescent lamps is the most used lamp as source of lighting. However, they contain mercury, which is classified as heavy metals, that can potentially harm the environment. Even as mercury container, many people didnt know that. Many people dont know the method to handle the broken or used compact fluorescent lamp. They just dispose the broken compact fluorescent lamp to trash without considering the effect of mercury contained.Inverse Manufacturing concept is about designing product life cycle that aims to repair and reuse product components so that the negative impact can be reduced and minimized. In this research, the concept of Inverse Manufacturing is applied on handling the compact fluorescent lamp product in Bandung, West Java. The study is begun with designing the Inverse Manufacturing conceptâs model by adding the step of collecting back (two scenarios), sorting, repairing, remanufacturing, and recycling into the life cycle of compact fluorescent lamp. The results of recycling rates of 15 Watt compact fluorescent lampÂ (about 234 grams) starts from the lowest value,Â and the maximum value are 27,51 % (64,366 grams),Â and 27,61 % (64,609 grams). By applying this concept, the result are the reduction on the amount of compact fluorescent lamp waste dumped into the environment and the achievement ofÂ the conservation of natural resources through the reuse of used components.

Safety climate is an important component of the responsibility of health services and the safety climate survey provides a measure of the safety climate within the organization and identifies opportunities to improve service. Implementation of safety climate in healthcare has been done in many developing countries or developed countries, assessment of safety climate on healthcare by using questionnaires. Low safety culture has a positive contribution to the errors in health services, unsafe therapy, and a variety of other unexpected accidents (medical errors, unsafe therapies, and unintended injuries). Based on this background, this study aims to evaluate the existing safety climate at the regional general hospital in Yogyakarta province, and to know the general picture of the safety climate condition in the hospital. This study was conducted at the emergency department at the hospital with 3 hospitals in Yogyakarta with 84 respondents consisting of nurses, doctors and midwives working in the unit. The results obtained from this study resulted in a valid and reliable questionnaire for each dimension with validity> 0.3 and reliable over 0.6, and also the validity results from questionnaires on other hospitals resulted in consistency of psychometric questionnaires. In this study also shows the index level of each dimension to the hospital. Overview of each hospital on the safety climate can be illustrated based on the level obtained that RSUD II and RSUD I leadership, communication, and also teamwork already has a pretty good level, while RSUD III 3 dimensions that are at level 1 for the dimension of leadership , personal and communication. The personal dimensions of the three hospitals are at level 1 explaining that personal dimensions are still poor in all three hospitals. And also from result of test of Mann Whitney can be seen that there is no difference of perception between doctor and nurse so that equation of perception toward interest of safety climate same between doctor and nurse at RSUD Yogyakarta
