Abstract

Frequent complaints about the gap between the number, quality and ability of graduates with the criteria needed by the world of work appear in the field and the still low Index of Technology Development, Information and Communication in Indonesia are two national problems that must be addressed carefully. In this regard, the Indonesian National Qualifications Framework (KKNI) policy is a solution that has been established by the government to improve the quality of Indonesia's human resources. In order to support the efforts to manifest Indonesian people who are superior and have global competitiveness, the researchers want to analyze the implementation of KKNI-based learning in the Industrial Revolution Era 4.0 in the Mathematics Education Study Program of HKBP Nommensen Pematangsiantar University (UHKBP-NP). It is hoped that this research can become a reference material for the government in reviewing and evaluating the effectiveness of the KKNI program so that different policies can be formulated according to the reality on the ground. This research problem will be revealed with a qualitative method approach because the things to be revealed are phenomenological. To collect all the required research data and information, the researcher will use three techniques, namely interviews; observation; and documentation. The data that has been collected will then be analyzed using focused observation techniques and interactive analysis techniques.

Abstract

Dalam hal pendistribusian barang, setiap kantor pos pasti memiliki wilayah distribusi tujuan. Begitu juga dengan Kantor Pos di Jl. Sutomo no. 2 Pematangsiantar, dimana mereka bertugas mendistribusikan barang di wilayah Kota Pematangsiantar yang merupakan puncak simalungun. Agar barang tersebut dapat didistribusikan dengan cepat maka diperlukan rute yang efisien dari segi jarak. Pendistribusian barang dimulai dan diakhiri di Kantor Pos kota Pematangsiantar. Masalah tersebut dapat dikategorikan sebagai Travelling Salesman Problem (TSP) yaitu suatu masalah dimana seorang salesman harus mengunjungi semua daerah yang setiap daerahnya hanya dikunjungi satu kali, dan harus kembali kekampung halaman. Tujuan dari penelitian ini adalah untuk mengetahui waktu tersingkat dalam menyampaikan pesanan, membantu perusahaan dalam menekan biaya operasional, mendapatkan jalur terpendek menggunakan dua cara yaitu dengan cara perhitungan manual dan bahasa pemrograman sehingga menjadi bahan acuan bagi mahasiswa Universitas HKBP-N Pematangsiantar, Kantor Pos, serta perbandingan efisiensi menggunakan pascal.

Abstract

The three-dimensional linear log model is an equation in the form of a model in statistics that is used to describe whether there is a relationship between two or more variables and the pattern of their relationship at the same time to find out which cells cause dependencies. The number of variables discussed in this study was three variables. After the variables are investigated, the formation of a log-linear model becomes important because not all the model factor interactions that exist in the complete model are significant in the resulting model. This study aims to perform linear log modelling to obtain a suitable final model, using the Forward method for case examples of qualitative data. From the examples of cases that have been worked on, it is known that the Forward method is the best model building method because this method is used more as a process of adding one by one the interaction between factors in the model to evaluate the fit of a model. This will provide an alternative choice in determining the best model after going through the fittest for each model that is formed.

Abstract

The population growth rate of an area is influenced by several factors including fertility, mortality and migration. Meanwhile, population counts are usually carried out through a population census which is carried out every 10 years. As a metropolitan area, every year North Sumatra experiences a very rapid population growth rate. The population growth rate can be modelled with a stochastic model. In stochastic modelling refers to the percentage calculations for fertility, mortality and migration in predicting for the next census year period. Meanwhile, to calculate the population, you can use numerical methods, namely, forward newton Gregory polynomial and reverse newton Gregory polynomial. The method used in this study is a literature study where the data source used is secondary data and in this case, the researcher analyzes between three census periods, namely the period 1980 to 2010 and then predicts the period of the next census year. The purpose of this study was to determine the effectiveness of the three models in predicting the population of North Sumatra in the census period. For stochastic modelling, the prediction results obtained for the year 2010 are the percentage of total birth rate or fertility reaching ± 17.67%, the mortality reaches ± 39.61% and the migration reaches ± 42.72%. For 2020, the probability that the percentage of total birth or fertility is ± 16.83%, the mortality is ± 33.85% and the migration is ± 49.36% and for 2030 the probability of the percentage of total birth or fertility is ± 16.98%. the mortality reached ± 34.28% and the migration reached ± 48.74%. And for the forward newton Gregory polynomial method and the reverse Gregory newton polynomial, the total relative error is obtained respectively while for the reverse newton Gregory polynomial method the total error value is. Referring to the error value, the advanced Newton Gregory polynomial method has better accuracy.
