Abstract

Abstrak Graf pangkat pada semigrup adalah sebuah graf tak berarah yang himpunan titiknya adalah dan dua titik berhubungan langsung jika dan hanya jika dan atau untuk suatu bilangan bulat positif Setiap titik di graf pangkat berhubungan langsung dengan satu dan hanya satu elemen idempoten di semigrup dan tidak ada dua idempoten yang terhubung oleh sebuah lintasan yaitu setiap komponen di graf pangkat memuat idempoten tunggal untuk setiap titik pada komponen yang berhubungan langsung. Selain itu, graf pangkat terhubung jika dan hanya jika memuat idempoten tunggal. Sehingga semigrup paling banyak memiliki satu idempoten. Akibatnya jika grup hingga, maka graf pangkat selalu terhubung dan graf pangkat lengkap jika dan hanya jika grup siklik berorder atau Kata Kunci: Graf pangkat, berhubungan langsung, terhubung, lintasan, semigrup, grup, graf lengkap, grup siklik. Abstract Power graphs of semigroups is an undirected graph whose vertex set is and two vertices are adjacent if and only if and or for some positive integer Every vertex in P(S) is adjacent to one and only one idempotent in and no two idempotens are connected by path i.e., each component of contains a unique idempotent to which every other vertices of that coomponent are adjacent. Moreover, is connected if and only if contains a single idempotent. So that, contains at most one idempotent. As consequence, is connected for any finite group and is complete if and only if is a cyclic group of order or Keywords: Power graph, Adjacent, Connected, Path, Semigroup, Group, Complete graph, Cyclic group

Abstract

Red Spinach (Amaranthus tricolor L.) has many health benefits, one of which is in the healing process of burns. The aim of this research was to determine the effectiveness and concentration of ethanol extract of Red Spinach leaves (Amaranthus tricolor L.) which is effective in the healing process of burn wounds in male white rats (Rattus norvegicus). The research method used is experimental. The results of the phytochemical screening of the ethanol extract of red spinach leaves contain flavonoids, alkaloids, saponins and tannins. The effectiveness test in the healing process of burn wounds used 25 experimental animals which were divided into 5 treatment groups, namely negative control group (HPMC base), positive control (Bioplacenton), and extract group with concentration variants of 5%, 10%, and 20%. Observation of the burn wound healing process was carried out by measuring the diameter of the wound on days 2, 4, 6, 8, 10, 12, 14 where the average diameter was calculated as the percentage of burn wound healing. Statistical analysis was carried out using the One Way Anova test with a significant value of p: 0.000 and continued with the LSD test. The results of the study stated that 70% ethanol extract of red spinach leaves had activity in the healing process of burn wounds in male white rats. The concentration dose that was most effective in healing burns in male white rats was 70% ethanol extract of red spinach leaves with a 20% concentration.
