Abstract

3D Printing is the process of making products from a digital design into three-dimensional shapes that can be seen and can be held, and have volume. Where 3D Printer is a technology that has a bright future, even the technology is still growing and supporting humans for technological advancement. 3D Printer Type FDM (Fused Deposition Modelling) is very often used because it is easy to print three-dimensional objects at low cost and also filament material that has been widely available. By using the Taguchi method to find out the optimal process parameters, where finding the larger value is better in the results of the tensile test plot means and S/N ratio using analysis software and manual calculations. Using the SOVOL SV06 brand 3D Printer machine and SUNLU brand PETG filaments, it was found that the Print Speed factor or parameter greatly affects the tensile test strength according to ASTM D638 Type IV standards. Where after tensile tests and data processing both manually and with the help of software, the S/N ratio value was found with a sequence of parameters, namely Print Speed (50 mm/s), Layer Height (0.24 mm), Print Temperature (250 °C) and Infill Density (50%).

Abstract

This research aims to determine whether there is a relationship between perceptions of organizational support and perceptions of workload and work-life balance among electronic service employees in Bojonegoro. A quantitative approach was used in this research. The sampling technique used was saturated sampling using electronic service employees in Bojonegoro who were tasked with handling electronic service in workshops and on call, totaling 30 employees. The instruments used in collecting data were a scale of perceptions of organizational support, a workload scale, and a work-life balance scale, which were presented in the form of a Likert scale. Hypothesis testing the data analysis method used is the multiple correlation test using SPSS 22 software. Based on the results of the analysis, it can be seen that the significance value (p value) is 0.002 with a significance level of 0.05. So, it can be concluded that p < 0.05. From the calculation results, the calculated F is obtained at 5,881. The F table value with three variables and N=30 respondents obtained a value of 3.316. So that F count > F table. Thus, it can be concluded that one research hypothesis can be accepted, namely that there is a relationship between perceptions of organizational support and perceptions of workload and work-life balance. At the correlation coefficient level, it is known that this research has a correlation coefficient value that is included in the moderate relationship level, namely 0.551. This means that there is a relationship between perceived organizational support, perceived workload, and work-life balance.

Abstract

Lumintu is one of the SMEs engaged in the production of 'balung kuwuk' and banana chips. In marketing its products, Lumintu faces a challenge of unstable sales. This research utilizes the SWOT Matrix IFE-EFE and Quantitative Strategic Planning Matrix (QSPM) methods. The IFE-EFE matrices are used to identify the Internal and External factors that influence the product sales in Lumintu SME. The purpose of the IFE and EFE matrices is to determine the ranking value and weight of each internal and external factor. The analysis is then continued using the Quantitative Strategic Planning Matrix (QSPM). The result of the methods used indicates that the marketing strategy for 'balung kuwuk' and banana chips products falls into quadrant 4, which represents the 'Grow and Build' strategy. This quadrant is derived from the total score of IFE matrix weight (3.11) and the total score of EFE matrix weight (2.93)."

Abstract

Basically, the control of maintenance/maintenance can be determined according to business needs and operating conditions. However, changes may occur and require adjustment from time to time. So every part of the maintenance needs to organize the system effectively. In this regard, it is important for management to pay attention to analyzing the implementation of Total Productive Maintenance (TPM) on maintenance work. At the SKN Plant which is the Central Gas Plant there are several gas processing processes, one of which is the Amine System or CO2 Removal which functions to reduce the level of CO2 contained in gas production. In the Amine System or CO2 removal process there are several equipment to support the process One of these is the Amine Circulation Pump (SK 25 P 05 A/B) which runs continuously alternately unit A and unit B. To maintain the pump's performance, the company performs maintenance by implementing a Total Productive Maintenance (TPM) system. The extent to which the effectiveness of the implementation of the TPM system carried out by Pertamina Hulu Rokan Jambi Merang, the author will analyze using the Overall Equipment Effectiveness (OEE) approach to the Amine Circulation Pump (SK 25 P 05 A/B). The formulation of the problem in this research is the application of Total Productifities Maintenance (TPM) on the Amine Circulation Pump (SK 25 P 05 A/B) in the CO2 removal process (Amine System) using the Overall Equipment Effectiveness (OEE) approach with the aim of knowing the level of reliability of the pump. Amine Circulation (SK 25 P 05 A/B) in the CO2 removal process (Amine System) using the Overall Equipment Effectiveness (OEE) approach. The results of this study are the average Overral Equipment Effectiveness value at PT Pertamina Hulu Rokan Jambi Merang on the amine circulation pump engine SK 25 P05 A/B from January-December is 56.68%. Based on the analysis of Overall Equipment Effectiveness, the current maintenance system is not optimal because it is not in accordance with the standards set by JIPM of > 85%.

Abstract

Abstrak: Poliester (Polyester) merupakan jenis material polimer thermosetting yaitu jenis material diman terbentuknya ikatan dibantu oleh panas, katalis atau gabungannya. Matriks ini dapat menghasilkan keserasian matriks-penguat dengan mengontrol faktor jenis dan jumlah komponen, katalis, waktu, dan suhu. Sifatnya tahan creep, memadai selaku perekat struktur berbeban berat, serta tahan kondisi ekstrim panas, radiasi, kelembaban, dan tahan kimia.Bunyi merupakan penyimpangan tekanan pada medium pengantar akibat energi yang dirambatkan dalam bentuk gelombang oleh sumber getar (Latifa, 2015). Koefisien penyerapan bunyi (α) adalah angka yang menunjukan kemampuan material menyerap energi bunyi. Makin besar koefisiennya, daya serapnya makin tinggi. Penelitian ini dilakukan untuk mengetahui efektivitas peredam kebisingan komposit resin polyester dan serat sabut kelapa. Hasil pengujian akustik komposit ini diperoleh untuk sampel 20 gram, 30 gram dan 40 gram sabut kelapa terlihat bahwa kemampuan meredam bunyi/coefisien absorption (α) terendah adalah -0,006 pada sampel 20 gram sabut kelapa dengan frekuensi 125 Hz dan tertinggi adalah 0,428 untuk sampel 40 gram sabut kelapa pada frekuensi 1000 Hz. Kata Kunci : Komposit, Peredam Kebisingan, Sabut Kelapa
