Damaris Lalang1, Samuel Rex Mulyadi Making2, Imanuel Yosafat Hadi Manapa3 1Department of Mathematics, Universitas Tribuana Kalabahi, 85812 Kalabahi 2Mathematics Education Department, STKIP weetebula, 87254 Sumba Barat Daya 3Department of Mathematics, Universitas Tribuana Kalabhi, 85812 Kalabahi Email: dhamar.ipb14@gmail.com; rexmaking@gmail.com, manuelmathematics@gmail.com
Distribution is the process of distributing goods from producers to consumers. This distribution process requires operational costs and costs when using vehicles to distribute goods. In the process of distribution, all producers must expect to be able to minimize costs. Therefore, the company must be able to find a solution to minimize the costs incurred. One such solution is by using the services of the driver occasionally. Occasional drivers, referred to here, are ordinary people, who are not from shipping companies, who have vehicles that are not fully used in everyday life; these vehicles can be used to deliver goods from producers to consumers. There are several problems that are often faced in the distribution of goods including the determination of routes that can minimize total costs. In determining the route, each producer has different constraints, such as the number of vehicles used, vehicle capacity, consumer demand, distance between consumers, and there are also cases where consumers want to be served according to the time windows they have. The problem of determining the optimal route can be solved by a model in optimization, namely Vehicle Routing Problem (VRP). This VRP is modelling in optimization that aims to optimize the ability to minimize distribution costs. This scientific work aims to formulate the problem of distribution in model multi-depot vehicle routing problem (MDVRP) that has a time limit by using the services of the driver occasionally to minimize total costs. The MDVRP settlement, with occasional drivers, has more than one depot that acts as a company or producer of a product. The results of this model formulation show that this model can be used to minimize distribution costs. Page 39 to 60 |

Pikir Wisnu Wijayanto Telkom University, Bandung, Indonesia Email: pikirwisnu@telkomuniversity.ac.id
This research aims to identify the meaning of sentences, in detail, from a discourse semantics’ perspectives, through metafunctions analysis of ideation systems introduced by James Martin and David Rose (Martin & Rose, 2003). This research makes use of qualitative and descriptive methods with data obtained from the "Opinion Forum" of the Jakarta Post published on February 18th, 2019, entitled “Islam Nusantara: A Soft Power Diplomacy” written by Arifi Saiman. According to a metafunctions analysis of the phase ideation sequence and ‘circumstances’ process, the sentences expressed the writer’s opinion, expectation, and suggestions with regards to Islam Nusantara concepts. In the sequence of activities and descriptions, each clause mostly expressed what they act, speak or feel. There were also some circumstantial processes that have been proven by a ‘wh-items’ in this article, such as ‘doing’, ‘saying’, and ‘sensing’. These are used to express the writer opinion, suggestion, and ‘high’ expectation to the Islam Nusantara concepts as an extension of its now well-known soft power diplomacy of organizing interfaith dialogues.

Putu Agus Indrawan and Andriyani E. Lay Guidance and Counseling Study Program, Faculty of education and Teacher Training, University Of Nusa Cendana Email: putu.indrawan@staf.undana.ac.id; andriyanielay@staf.undana.ac.id
This study discusses the competencies that must be owned by guidance and counselling teachers in schools in this era of industrial revolution 4.0. A guidance and counselling teacher is trained in higher education to fulfil four competencies and make them integrated. The competencies are 1) pedagogical competency, 2) professional competency, 3) social competency, and 4) personality competency. In this era of industrial revolution 4.0, guidance and counselling teachers need a change of perspective in giving service to students in order to be able to have higher competitiveness and competencies. BK teachers are also expected to be able to balance the development of students in the millennial era with a more efficient, effective, and flexible approach. Therefore, guidance and counselling teachers need to develop four additional competencies namely; 1) critical competency, 2) creative competency, 3) communicative competency, and 4) collaborative competency. The development of these competencies is obtained through lecture activities, seminars, training/courses, and other relevant development activities. Pages 147 to 161 |

Sediono, Eko Tjahjono, and Retno Dwi Puspitasari Department of Mathematics Airlangga University Email: sediono101@gmail.com
The transfer function model is one of the quantitative prediction models that is often used for multivariate time series data prediction. This model combines several characteristics of regression analysis with ARIMA periodical characteristics. This research explained the application of a single input transfer function model in predicting the amount of electricity consumption (Yt) in Jombang Regency based on the influence of the average air temperature (Xt)). In conducting modelling, the data used electricity consumption and the average air temperature from January 2011 to June 2017. The stages that need to be done are to see the stationary data of the output series (Yt) and input series (Xt), determine the best ARIMA model output series (Yt) and input series (Xt), do prewhitening, determine the order (b, r, s) through cross correlations (CCF) plots, and determine the best model of the transfer function by describing the order (b, r, s) along with the sequence (nt). From the model produced it can be explained that the amount of electricity consumption in Jombang is influenced by the increase in electricity consumption 1 month before (), minus 1202862.9 times the average air temperature this month () minus the average air temperature 12 months ago (), minus the average air temperature 13 months ago () ̇ plus the residual this month () minus 0.83127 times the residual 1 month ago ().

Profitability Level Modelling of Manufacturing Companies based on Binary Logistic Regression with Random Effect on Panel Data
Email: suliyanto@fst.unair.ac.id
The manufacturing company is the main pillar of industrial development in a country. The development of manufacturing industry can be used as a benchmark to see national industrial development in the country. The performance of a good manufacturing company can be seen from profitability. Profitability is the ability of companies to earn profits in relation to sales, total assets capital. Profitability ratios are measured by Net Profit Margin (NPM). This ratio measures the ability of a company to generate profitability at a certain level of sales, assets, and capital stock. The greater the Net Profit Margin, the more efficient the company is in issuing the costs associated with its operations. The relationship between profitability and the factors that influence it will be studied to obtain a mathematical model. This mathematical model will show the factors that influence profitability significantly. Predictor variables which determine profitability are Leverage, Manufacturers’ Size, Liquidity, and Tangibility. In conducting research on profitability, the data used is a combination of cross section and time series or panel data. This data is used because it is necessary to observe the behavior of research units at various time periods. This study used secondary data of 2008 – 2016 Annual Reports which were downloaded from 21 related manufacturers’ official websites. One of the statistical analysis tools used, to observe the behavior of research units at various time periods, is ordered logistic regression analysis in panel data, which is an extension of logistic regression when it is used in panel data. Estimation of binary logistic model parameters in panel data using maximum likelihood estimation method with Gauss-Hermitte Quadrature iteration. Based on the best model obtained, the factors that influence manufacturers’ profitability, in Indonesia, are leverage and tangibility. The result of the Likelihood Ratio Test shows that the random effect panel binary logistic regression model is better model than standard binary logistic regression with a classification of accuracy of 73.54%.

How Does Metacognition of Senior High School Students Participate in Mathematical Problem Solving Process
Kristiana Reinildis Aek, Imam Sujadi and Sri Subanti Universitas Sebelas Maret, Surakarta, Indonesia Email: aekrenny@gmail.com
Metacognition is an important factor in mathematical problem solving. It is the ability to monitor and control our own thoughts, how to approach the problem, how to choose the strategies to find a solution, or to ask ourselves about the problem. In other word, metacognition can be defined as think about thinking. By using metacognition, students will solve mathematical problems precisely because they are aware of the thinking process to plan, monitor and evaluate each step taken. This study was conducted to identify students' metacognition profiles in solving mathematical problems. It is descriptive qualitative research. The research was conducted in Class X SMAN 1 Surakarta. Data was collected using a written test and task-based interviews. Based on data analysis, the subjects cannot fulfill all indicators of the stages of metacognition, namely planning, monitoring and evaluation. So it can be concluded that not all students can use their metacognitive abilities well. Pages 217 to 226 |

Development of Geographically Weighted Regression Using Polynomial Function Approach and Its Application on Life Expectancy Data
Toha Saifudin, Suliyanto, Elly Ana Department of Mathematics Faculty of Science and Technology University of Airlangga Email: tohasaifudin@fst.unair.ac.id
Geographically Weighted Regression (GWR) is a varying coefficient model. However, as an extension of Ordinary Linear Regression (OLR), it models a dependent variable at each location as a linear function of a set of independent variables. In real life, one or more independent variables involved in the model may have nonlinear relationships with the dependent variable. For this case, the GWR model is no longer realistic to use since the resulted analysis lead to be misleading. To overcome the problem, we develop the GWR by using a polynomial function approach. Here, the model is called Geographically Weighted Polynomial Regression (GWPolR). This paper aims to provide an algorithm, based on Akaike Information Criterion (AIC), for finding the optimal bandwidth and polynomial degrees. Furthermore, this paper aims to analyze life expectancy data in East Java province, Indonesia based on human development index and per capita expenditure. Compared with OLR and GWR models, GWPolR gave a significant improvement of goodness of fit measures and a more complete explanation of how each independent variable was related to the life expectancy.
