Abstract

Research has been carried out by developing an optimization information system for scheduling production machines by applying the Android-based GUPTA method. This android-based application is able to optimize production time, because in the android application it implements the GUPTA algorithm which uses the calculation of the comparative processing time on every machine in the company by prioritizing the smallest processing time for scheduling which aims to optimize production scheduling time, by paying attention to the value of makespan to produce product size 12 griddle, size 14 griddle, 16 size griddle, 18 size griddle and 20 size griddle so that an optimal makespan value is obtained. The GUPTA method can be used in problems with more than two machines, because this method combines the time of each process on the first and subsequent machines to find the minimum value and can only be used in pure flow shop scheduling. The advantage of this method is that it determines scheduling only on one machine group. This research resulted in an Android-based application that can schedule products to be produced by machines automatically. From the results of testing with a total of 12 pieces of production in each product with a total of 5 different sizes, the minimum value of makespan is obtained, namely 2054569 minutes with the sequence of product processing with work order 12 griddle, griddle 18, griddle 20, griddle 16, and griddle 14 The accuracy of the application test results shows 98.87% for the first time and 98.84% for the second time when compared with manual calculations.

Abstract

Research on optimizing production time using the dudek smith campbell algorithm (CDS) in scheduling the production process aims to makepan optimization for machine operations to produce 12 size griddle products, 14 griddle sizes, 16 griddle sizes, 18 griddle sizes and 20 griddle sizes to get the makepan values. optimal. The method applied by the Campbell Dudek and Smith (CDS) algorithm, CDS is a method used in flowshop scheduling developed from Johnson's rule which is able to minimize the makespan of 2 machines arranged in series. The CDS method is very suitable for production characters who apply machine sequences to the production process. CDS produces several iterations that have the value of makespan, from those iterations, the minimum value of makespan is to determine the order of products to be produced. This research resulted in an application that can schedule products to be produced by machines automatically. From the test results with a total production of 12 pieces on each product with 6 repetitions, the minimum value of makespan is 210.12 minutes with a sequence of product works 20 pans, 18 pans, 16 pans, 14 pans, and 12 pans. Accuracy of results Application testing shows 99.99% for the first time and 99.96% for the second time when compared to manual calculations

Abstract

 Beberapa Perguruan Tinggi Swasta (PTS) di Jombang menerapkan proses seleksi Penerimaan Mahasiswa Baru (PMB) online, sehingga pendaftar cukup mendaftar melalui website PMB online milik masing-masing PTS, tanpa perlu ke Perguruan Tinggi (PT) tersebut. Namun dalam pelaksanaanya masih terdapat calon mahasiswa yang mendaftar secara langsung ke kantor PMB PTS, hal tersebut menjadikan perlunya pengukuran tingkat kesuksesan penerapan website PMB online di PTS. Selain itu, selama ini website PMB online PTS di Jombang belum pernah dilakukan evaluasi untuk mengetahui tingkat keberhasilannya. HOT (Human Organization Technology) Fit model merupakan model kesuksesan yang dapat dijadikan model dalam mengevaluasi sistem informasi. Terdapat 7 variabel yang digunakan HOT Fit, yaitu kualitas sistem (system quality), kualitas informasi (information quality), kualitas layanan (service quality), pengguna sistem (system use), kepuasan pengguna (user satisfaction), manfaat (net beneFits), struktur organisasi (organization structure). Hasil penelitian menunjukkan terdapat 3 indikator penilaian dengan nilai kepuasan di bawah 85%, yaitu kecepatan waktu respon 76,1%; adanya fasilitas bantuan 71,6%; dan kepuasan tampilan 64,2%. Sehingga 3 indikator tersebut perlu ditingkat lagi untuk mendapatkan hasil yang lebih baik dan dapat mengoptimalkan penerapan website PMB online PTS di Jombang.   Private Higher Education (PHE) in Jombang apply online admission of new students selection process, so applicants simply register through admission of new students online website owned by their respective private universities, without needing to the university. But in the implementation there are still prospective students who apply directly to the office of admission of new students PHE, it makes the need to measure the success rate of admission of new students website online application in PHE. Also, so far admission of new students online website PHE in Jombang has never been evaluated to determine the success rate. HOT (Human Organization Technology) Fit model is a model of success that can be used as a model for evaluating information systems. There are seven variables used by HOT Fit, i.e., system quality, information quality, service quality, system use, user satisfaction, net beneFits, organizational structure (organization structure). The result of the research shows that there are three assessment indicators with satisfaction value below 85%, the response time is 76,1%; the availability of 71.6% of aid facilities; and 64.2% display satisfaction. So that three indicators need to be increased again to get better results and can optimize the implementation of admission of new students website online PHE in Jombang.
