Abstract

To control the production quality in terms of product weight, PT. X needs a standardization in production process. The weight standardization will help ease stocking process for both the company and the distributor. This research is used on the hollow product with chain type A with gold levels of 70%. Some of the products weight are not constant due to the variation of shrinkage percentage in every production process. The solution for this problem is to reduce the variation of shrinkage percentage levels in every production process using PDCA method. The improvement results obtained from PDCA method is shown on hammering, hollowing, and bombing process. On hammering process, a decrease in the shrinkage percentage variation is done by controlling the wire’s thick shrinkage percentage 15%-20% for a 5% shrinkage percentage. The percentage of necklace on hollowing process can’t be controlled, as a result an improvement is needed by giving an accurate range percentage standard, 49%-52% for chain A with gold levels of 70%. The weight shrinkage percentage in bombing process is depending on the size of small, medium, and large chain respectively 4%-5%, 5%-6%, 6%-7%.

Abstract

Lately the number of small and medium industry in Indonesian increase sharply, even though this growth was not followed by the development of internal organization and the innovation environment. While the development of internal organization and innovation may improve the performance of the small and medium industry. This research aims to model the increase in performance of shoes industries at Mojokerto thorugh the innovation atmosphere which can be influenced by internal organization as well. We used Structural Equation Model­ling (SEM) to model the three variables (Interanal Organization, Innovation Atmosphere, and Performance) and developed questionnaire for the latent variables. We found that the internal organization which supported by the atmosphere of innovation did not significantly influence the industry performance.

Abstract

The research is conducted to analyze the causes of new employee resigning the company. The new employee resigned during 2018 with the working period less than three months. The resigning new employee created loss in time and cost for the company. The analysis is done using paretto diagram to determine the cause that should be solved. The analysis continued using fishbone diagram. There are two factors causing the employee to resign, they are abandonment and performance. Abandonment is caused the employee getting a new job. Performance is caused by the employee having sub par performance. The research on employee performance gives solution to the resigning employee through interviewing based on interest and competence, completing the induction program, recruiting trainer, expanding the size of the training room, and adding tools and system to monitor the materials.

Abstract

5S merupakan konsep penerapan sikap kerja yang menekankan pada pengelolaan kondisi fisik tempat kerja. 5S merupakan singkatan dari Seiri, Seiton, Seiso, Seiketsu, dan Shitsuke. Bekerja pada tempat yang terorganisir, membuat pekerja tidak cepat lelah, menimbulkan kepedulian terhadap pekerjaan, partisipasi yang tinggi, dan penyelesaian kerja yang baik. Penerapan konsep 5S pada area penyimpanan sangat penting karena berpengaruh terhadap efisiensi dan efektifitas pekerjaan. Tujuan penelitian ini adalah melakukan penilaian dan evaluasi konsep 5S di area penyimpanan proyek, untuk mengetahui sejauh mana konsep 5S telah diterapkan. Penelitian ini dilakukan dengan studi kasus pada 5 proyek konstruksi di Surabaya dan Mojokerto. Hasil penelitian menunjukkan bahwa konsep 5S belum diterapkan sepenuhnya pada proyek konstruksi. Seiso mendapatkan nilai yang cukup baik, mengingat kebersihan wajib dijaga di area proyek. Sedangkan, faktor seiri, seiton, dan shitsuke mendapatkan nilai yang buruk, karena 4 dari 5 proyek yang ada masih menyimpan alat rusak, tidak ada tata letak untuk area penyimpan alat, dan kurangnya kesadaran akan kedisiplinan. Seiketsu mendapatkan nilai yang sangat buruk karena aktivitas yang dinilai merupakan lanjutan dari 3S sebelumnya. Konsep 5S belum diterapkan di proyek konstruksi karena belum dikenalnya konsep 5S, kesulitan melakukan pengarahan dan pelatihan pada pekerja, adanya deadline proyek, serta jumlah dan jenis alat yang sedikit.

Abstract

Oil and gas companies are currently facing increasingly significant production declines, requiring detailed, accurate and fast subsurface analysis. However, the complexity of large and scattered data, as well as the use of various non-integrated software, are obstacles that cause difficulties and long and inefficient analysis times. Therefore, this study aims to design an intuitive graphical user interface (GUI) dashboard to speed up and facilitate the process as part of the technology management of one of the oil and gas companies in Indonesia. The design thinking and new product development approaches are used to design the system. Qualitative methods are carried out through in-depth interviews, field observations, and surveys to identify user needs and build a subsurface dashboard GUI system, while quantitative methods are used to analyze multi-matrices from the House of Quality (HoQ) and evaluate the intuitiveness and usability of the prototype with the System Usability Scale (SUS) instrument. The analysis was carried out using user personas, customer journey maps, and HoQ to determine the main features. The results of the study indicate that visual graphics, seismic maps and cross-sections, customization, and data management are priority features in the subsurface dashboard GUI system prototype. The SUS evaluation shows that the system is intuitive, user-friendly, and can support work efficiency, as well as suit user needs.

Abstract

Nowadays, internationally recognized test results of construction materials are critical for companies handling government projects in the construction sector. A university's Concrete and Construction Laboratory sees commercialization as a way to expand its capacity and usage to this potential market. The standardization strategy employed in this research is to implement and obtain ISO 17025:2017 accreditation. Preparation of required documents is carried out as the first step in preparing for accreditation. Preparation is done by identifying document requirements, identifying business processes, identifying document completeness using a checklist, analyzing document completeness, and generating conclusions. The results of the identification and analysis of the completeness of the documents using the checklist show that the documents that need to be made by this University’s Concrete and Construction Laboratory are as many as 70 documents and the four documents that have been owned need to be adjusted according to the requirements of ISO 17025:2017.

Abstract

This research aims to analyze the technology readiness and technology acceptance rate of UT Connect application users in the heavy equipment industry using the Technology Readiness and Acceptance Model (TRAM) approach. The analysis was carried out through the Structural Equation Modeling – Partial Least Square (SEM–PLS) method, including testing the outer model, inner model, and conducting hypothesis testing to assess validity, reliability, and relationships between constructs. The results of the study showed that all constructs met the criteria for validity and reliability. In terms of technological readiness, Optimism has a significant effect on Perceived Usefulness, while Innovativeness, Discomfort, and Insecurity have no effect on either Perceived Usefulness or Perceived Ease of Use. These findings indicate that users have a good level of readiness to embrace digital innovations, even though negative factors do not have a significant influence. Regarding technology acceptance, the variables Perceived Enjoyment, Technology Self-Efficacy, Perceived Ease of Use, and Perceived Usefulness have a significant influence on user attitudes (Attitude Toward Using) and actual usage behavior (Actual Usage). The relationship between Perceived Ease of Use and Perceived Usefulness was also found to be strong, and users’ positive attitudes have an effect on their use of the application. The findings of this study provide empirical evidence that the TRAM model can explain the factors influencing the acceptance and use of digital applications and can serve as a basis for enhancing the effectiveness of UT Connect implementation.
