BILANGAN KROMATIK HARMONIS PADA GRAF PAYUNG, GRAF PARASUT, DAN GRAF SEMI PARASUT
Get PDFThis article discusses the harmonic coloring of simple graphs G, namely umbrella graphs, parachute graphs, and semi-parachute graphs. A vertex coloring on a graph G is a harmonic coloring if each pair of colors (based on edges or pair of vertices) appears at most once. The chromatic number associated with the harmonic coloring of graph G is called the harmonic chromatic number denoted XH(G). In this article, the exact values of harmonic chromatic numbers are obtained for umbrella graphs, parachute graphs, and semi-parachute graphs
Developing Scrabble Wall for Students’ Vocabulary Learning
Get PDFMastering vocabulary could be one of the keys to be successful in learning English. Teaching by using a certain game could be an interesting way to increase students’ vocabulary. The aim of this study is to create a scrabble wall to help students improve their vocabulary. This study employed the research and development method, as well as the ADDIE Model's theory, which is divided into five stages: analysis, design, development, implementation, and evaluation. Interviews, exams, and expert validation checklists were used as study instruments. This study used 25 students as a sample of product implementation among eleventh-grade students of SMA Putra Juang Cianjur. Data were gathered from student interviews, test results (Pre-test and Post-test), teacher replies, and expert validation results. The data analysis revealed that the product was both good and valid. The scrabble wall can be used as a means to teach English, particularly vocabulary. The scrabble wall is helpful for students as well. It may be concluded that the use of scrabble wall can enhance students’ vocabulary mastery

Analisis Iklim Mikro Kawasan Berdasarkan Kerapatan Bangunan dan Vegetasi di Kawasan Institut Teknologi Bandung (ITB) Kampus Ganesha Bagian Selatan
Get PDFThis study was conducted with the goal to identify parameters for a comfortable and cool outdoor environment, particularly in a tropical country like Indonesia. However, no previous research has been conducted to investigate the relationship between building configuration, vegetation density, and climatic conditions in campus areas, particularly the ITB Ganesha campus. As a result, the purpose of this research is to identify and analyze the microclimate on the ITB Ganesha campus using Envi-MET simulations. Thermal comfort factors affected by building configuration and vegetation density are examined in order to determine the relationship between those factors and microclimatic conditions in the campus area. This study employs quantitative methods, including simulation using ENVI-met software and comparison of the characteristics of the areas with data from the simulation. According to the findings, areas with higher vegetation density and lower yet more organized building configurations are cooler and more comfortable than areas with lower vegetation density and lower yet less organized building configurations. This research could lead to new insights for campus planning and development, as well as help create a healthy and comfortable environment on the ITB Ganesha campus while facing the global climate crisis. Aside from that, this study can be used as a reference for decision-making in the field of urban and environmental planning to improve life quality by improving outdoor environmental quality.Penelitian ini dilakukan untuk mengetahui parameter dari lingkungan luar ruangan yang nyaman dan sejuk, terutama di negara tropis seperti Indonesia. Namun, belum ada penelitian sebelumnya yang menganalisis hubungan antara konfigurasi bangunan, kerapatan vegetasi, dan kondisi iklim di kawasan kampus, seperti di kawasan Institut Teknologi Bandung kampus Ganesha. Oleh karena itu, penelitian ini bertujuan untuk mengidentifikasi dan menganalisis iklim mikro di kampus ITB Ganesha. Faktor kenyamanan termal yang dipengaruhi oleh konfigurasi bangunan dan kerapatan vegetasi dianalisis untuk memahami hubungan antara faktor-faktor tersebut dengan kondisi iklim mikro di dalam kampus. Penelitian ini dilakukan menggunakan metode kuantitatif berupa simulasi menggunakan software ENVI-met yang kemudian dilakukan perbandingan antara tiap karakteristik kawasan dengan data hasil simulasi. Hasil penelitian menunjukkan bahwa area dengan kerapatan vegetasi yang lebih tinggi serta bangunan yang lebih rendah dan teratur memiliki kondisi iklim mikro yang lebih sejuk dan nyaman dibanding area dengan kerapatan vegetasi yang lebih rendah serta konfigurasi bangunan yang lebih tinggi dan padat. Penemuan ini dapat memberikan wawasan bagi perencanaan dan pengembangan kawasan kampus, serta memberikan kontribusi dalam menciptakan lingkungan yang nyaman dan sehat di kampus ITB Ganesha dalam menghadapi perubahan iklim global. Selain itu, penelitian ini juga dapat menjadi referensi bagi pengambil keputusan di bidang perencanaan kota dan lingkungan untuk meningkatkan kualitas kehidupan manusia melalui perbaikan kualitas lingkungan luar ruangan
