Abstract

Vertex coloring is a method giving colors to vertex in a graph, so that each neighborhood vertex has a different color. Chromatic numbers are the minimum number of colors that can be used to color the vertices on a graph G. The aim of this research is to optimize the storage of chemicals safely by applying the application of chromatic number of graph coloring and to determine whether the chemical storage in the laboratory is optimal or not. This study is using a qualitative observation research design. We use a graph coloring method to obtain optimal results. And we get data by observation, interview and documentation. The instrument that we used to collect data consist of chemical data form. The data analysis activity starts from collecting the lists names of chemicals until draw conclusions.The results of this study, using the Welch-Powell Algorithm we get the chromatic number is 4. So that by applying the chromatic number of graph coloring, we just need place chemical in the laboratory as many as 4 cabinets, so that the storage area more optimal laboratory compared to the previous storage area of ​​6 cabinets.

Abstract

Kondisi cuaca yang mudah berubah saat ini menyebabkan ketinggian gelombang di perairan Pulau Jawa Judul sulit untuk ditebak. Pulau Bawean adalah salah satu Pulau Kecil di tengah laut Jawa yang distribusi logistik dan aktivitas lainnya sangat dipengaruhi oleh kondisi laut Jawa. Sehingga diperlukan sebuah metode untuk mengidentifikasi model matematika ketinggian gelombang perairan Pulau Bawean agar dapat membantu instansi terkait dalam memprediksi ketinggian gelombang secara akurat. ARIMA merupakan salah satu metode dalam analisis data time series yang banyak digunakan untuk menganalisis data secara statistik untuk mendapatkan model terbaik berdasarkan perilaku data tersebut, salah satu diantaranya adalah data ketinggian gelombang. Dalam penelitian ini didapatkan bahwa ARIMA(2,1,0) merupakan model terbaik untuk ketinggian gelombang perairan Pulau Bawean.

Abstract

This study aimed to improve students' learning motivation in Mathematics through the use of Wayground software as an interactive learning medium at SMK PGRI 13 Surabaya. The study was motivated by the low level of students' learning motivation and participation in Mathematics classes, which were still dominated by conventional teaching methods, such as lectures and the use of whiteboards, making the learning process monotonous and less engaging. This study employed a quantitative approach using Classroom Action Research (CAR), which was conducted in two cycles. Each cycle consisted of four stages: planning, action, observation, and reflection. The research subjects were 37 students of Class X TKJ 1 at SMK PGRI 13 Surabaya. The research instruments included a learning motivation questionnaire using a Likert scale, student activity observation sheets, and documentation. The data were analyzed using descriptive quantitative analysis by comparing the results of the preliminary stage, Cycle I, and Cycle II. The findings showed that the implementation of Wayground effectively improved students' learning motivation. The average motivation score increased from 3.24 (81.00%) in the preliminary stage to 3.35 (83.75%) in Cycle I and 3.57 (89.25%) in Cycle II, representing an overall improvement of 8.25%. Student activity also increased from the good category (3.14) in Cycle I to the very good category (3.86) in Cycle II. Therefore, Wayground is considered an effective interactive learning medium for enhancing students' motivation in Mathematics learning at vocational high schools.

Abstract

This research was motivated by the low learning motivation of class X TKJ 1 student at SMK PGRI 13 Surabaya in mathematics. Based on initial observations, students found mathematics difficult and boring, and the teacher still used lecture methods without variations in learning media. The aims of this study were to determine students' responses and the effect of using Wayground software on students' learning motivation. The research used the Classroom Action Research (CAR) method of the Kemmis and McTaggart model conducted in two cycles. The research subjects were 37 students of class X TKJ 1. Data collection techniques used learning motivation questionnaires, observation, interviews, and documentation. The results showed that students' responses to Wayground were very positive with the average observation score increasing from 3.14 (Good) in cycle I to 4.00 (Very Good) in cycle II. Students' learning motivation also increased significantly from 83.75% in cycle I to 92.50% in cycle II, with an increase of 8.75%. The number of students in the Very High motivation category increased from 75.68% to 91.89%. All motivation indicators increased, with learning preparation being the highest increase (+0.24) and learning focus improving. The conclusion of this study is that the use of Wayground software is effective in increasing students' learning motivation and received very positive responses. This research is expected to be a reference for teachers in developing innovative and interactive technology-based mathematics learning.
