Abstract

LMS (Learning Management System) 'Virlenda' is one of the options of PGRI University Adi Buana Surabaya in developing modern learning (e-learning). The LMS Virlenda 'will be studied whether to have an effect on the variable specified by using the Technology Acceptance Model (TAM). There are 4 variables studied, namely the  perceived usefulness (X1), perceived ease of use (X2), Internet access (X3), and actual usage (Y1). Researchers took 174 sample students of LMS users 'virlenda'. The study also uses data analysis technique with the Structural Equation Model (SEM) approach with AMOS Graphics count tools for Technology Accepted Model (TAM) modeling. The results show that the technology acceptance model accepts the effect of perceived usefulness with actual usage with CR = 3.118 or CR > 1.96 for a significance level of 5% and the resulting p-value is 0.002. The technology acceptance model does not accept the effect of perceived ease of use on actual usage because CR = -0.475 or CR 1.96 for a significance level of 5% and the resulting p-value is 0.634. And the technology acceptance model accepts the effect of internet access on actual usage with CR = 2.633 or CR > 1.96 for a significance level of 5% and the resulting p-value is 0.008.LMS (Learning Management System) VIRLENDA menjadi salah satu pilihan Universitas PGRI Adi Buana Surabaya dalam mengembangkan pembelajaran secara modern (e-learning).

Abstract

Surabaya locomotive warehouse is one part of the company PT. Kereta Api Indonesia (Persero) as a place to store spare parts for repair and maintenance purposes, especially locomotives. The implementation of these inspections and repairs, of course, requires spare parts to facilitate the maintenance process which generally spare parts are placed in storage or warehouses. The problem in the Surabaya locomotive warehouse is that the arrangement of spare parts for bin boxes for each type of group is not always fixed so that the search becomes a bit hampered. This study aims to review the repair of bin box spare parts placement on a regular basis by using the First-In First-Out (FIFO) approach to sort bin box spare parts based on their movement flow. Based on the results of the analysis, the classification of bin boxes in each type of spare parts rack group based on the flow of movement in sequence is fast moving, medium moving, and slow moving. In the fast moving spare parts bin boxes are placed on the bottom row of shelves, bin boxes that have medium moving spare parts are placed on the second and third rows of shelves. Meanwhile, bin boxes that have slow-moving spare parts will be placed on the top shelf. After classifying the spare parts in the bin box, an addressing area is made on each row of the rack to determine the location of the spare part position.

Abstract

Bioplastics is a plastic composite material that can decompose quickly and is environmentally friendly when interacting with soil and microorganisms. The aims of the research are: to examine the optimal composition of bioplastics made from tapioca waste by adding blood clam shell chitosan and glycerol, to determine the quality of production bioplastics from tapioca waste with the addition of blood clam shell chitosan and glycerol, and to determine the chemical content of the clam shells. bioplastic function of tapioca with the addition of blood clam shell chitosan and glycerol. The method used is experimental. Production of bioplastic by mixing waste tapioca flour, chitosan, and glycerol with a composition of 65%:35%:5mL, 70%:30%:5mL, and 75%:25%:5mL and additional water. The sample was put into a water bath and stirred at a temperature of 80oC for 15 minutes. Bioplastics were printed in aluminum foil, dried at 100oC for 90 minutes and cooled at room temperature for 6 hours. Laboratory test samples with tensile strength, elongation at break, FTIR, and biodegradation tests according to SNI 7188.7:2016 in the category of bioplastic easily decomposed. The results of the tensile strength on PBA1 samples were 0.75 Mpa, PBA2 samples were 0.54 Mpa, and PBA3 samples were 0.34 Mpa. Test value for elongation at break the PBA1 sample is 23.68%, the PBA2 sample is 15.33%, and the PBA3 sample is 12.12%. The sample test results do not meet the quality standard value of SNI 7188.7:2016 for the bioplastic category. The optimal composition of bioplastics is found in the PBA2 sample using tapioca flour as raw material with chitosan and glycerol as much as 70%:30%:5mL with a tensile strength 0.54%, an elongation at break 15.33%, biodegradation of 43%, and has a bioplastic content with functional groups (C=C), (CO), (CH),(OH), (C=C), and (CH2)n in the FTIR test results.

Abstract

Non Destructive Test (NDT) merupakan langkah visual dalam pengawasan terhadap kualitas hasil pengelasan logam. Kebutuhan dasar ini merupakan rangkaian dari pembuatan Welding Procedure Specification (WPS). Pelaksanaan uji NDT dilakukan dengan Penetrant Test. Tujuan penelitian ini mengetahui kecacatan untuk 21 logam yang di las dengan arus 90 ampere dan 21 logam yang dilas dengan arus 100 ampere. Analisa data menggunakan odds ratio. Hasil penelitian diperoleh analisis bahwa arus mesin las SMAW yang menggunakan 90 ampere lebih banyak menyebabkan kecacatan berupa indikasi rounded mencapai 33,3 persen. Sedangkan arus mesin las 100 ampere lebih banyak menyebabkan kecacatan berupa indikasi linier mencapai 28,2 persen. Hasil analisis menunjukkan nilai odds ratio OR = 2,200 (95 persen CI 0,632 < OR < 7,660) artinya arus mesin las 100 ampere cenderung menyebabkan kecacatan indikasi rounded 2,2 kali lebih besar daripada yang arus mesin las 90 ampere.
