Abstract

Proper vertex coloring c of a graph G is a graceful coloring if c is a graceful k-coloring for k∈{1,2,3,…}. Definition graceful k-coloring of a graph G=(V,E) is a proper vertex coloring c:V(G)→{1,2,…,k);k≥2, which induces a proper edge coloring c':E(G)→{1,2,…,k-1} defined c'(uv)=|c(u)-c(v)|. The minimum vertex coloring from graph G can  be colored with graceful coloring called a graceful chromatic number with notation χg (G). In this paper, we will investigate the graceful chromatic number of vertex amalgamation of tree graph family with some graph is path graph, centipede graph, broom and E graph.

Abstract

Morals are habits or attitudes that are deep in the human soul where actions arise easily and effortlessly without prior consideration and are carried out repeatedly until they become habits and these actions can lead to good or bad actions. Ethics is a science that studies good and bad by considering human actions rationally, especially in terms of thoughts, feelings and goals of actions, as well as discussing good and bad as well as theories about morals and how to behave in society. Morals are a set of principles, values, or standards that guide human behavior regarding what is considered right or wrong related to ethics and are usually influenced by culture, religion, education, and individual experience. The differences between morals, morals and morals are the part that discusses good and bad issues based on revelation or the Al-Qur'an and hadith.Keywords: morals, morals, ethics

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas akun Instagram @hskakseto sebagai media penyebaran informasi mengenai Homeschooling Kak Seto. Latar belakang penelitian ini adalah meningkatnya penggunaan media sosial dalam menyebarkan informasi pendidikan non-formal. Metode yang digunakan adalah pendekatan kuantitatif dengan teknik survei kuesioner kepada 100 responden aktif, dipilih secara purposive dari pengikut aktif akun Instagram @hskakseto. Instrumen penelitian berupa skala Likert 1-5 dan dianalisis menggunakan uji regresi linier sederhana. Hasil penelitian menunjukkan bahwa akun Instagram @hskakseto dinilai efektif sebagai media penyebaran informasi dengan rata-rata keseluruhan tertinggi pada dimensi kemudahan akses skor 4,47. Pada aspek kualitas visual konten, ilustrasi dan tipografi menjadi dimensi tertinggi dengan nilai rata-rata 4,44. Uji regresi menunjukkan pengaruh positif dan signifikan antara kualitas konten visual terhadap efektivitas Instagram sebagai media informasi (signifikansi 0,001), dengan koefisien determinasi sebesar 21,7%. Hal ini menunjukkan bahwa meskipun kualitas visual berpengaruh, masih terdapat 78,3% pengaruh dari faktor lain. Penelitian ini merekomendasikan pengelolaan konten visual yang konsisten untuk meningkatkan jangkauan dan efektivitas informasi.
