Suppose $ G $ is a graph, where $ G = \{V (G), E (G) \} $. Graceful coloring is defined by $ c: V (G) \to \{1,2, ..., k \} $ which induces a proper edge coloring $ c': E (G) \to \{1,2, ..., k- 1 \}$ defined by $c'(xy)=|c(x)-c(y)|$, where $ k \geq 2 $, $ k \in N $. Coloring is said to be graceful if these 3 conditions are satisfied, namely the proper vertex color, the proper edge color, and the edge color, which are the absolute difference between the color of the accident vertex. The subgraph $H$ on that graceful coloring is smaller than the $G$. Furthermore, one of the subgraphs in the unicyclic graph family is a cycle graph. The graceful chromatic number on a graph denoted by $ \chi_g (G) $, is the optimum number of graceful colors from graph $G$. This research aims to find graceful chromatic numbers in the unicyclic graph family, namely bull graphs, net graphs, cricket graphs, caveman graphs, peach graphs, and flowerpot graphs. The results of this study indicate that $\chi_g(C_l) \geq 4$, where $C_l$ is a unicyclic graphs.

All graph in this paper is a simple and connected graph. We define $l: V(G) \to \{ 1, 2, 3,...k\} $ is called vertex irregular k-labeling and $w: (G) \to N$ the weight function with $[\sum_{u \epsilon N} l(u) + l(v) ]$. A local irregularity inclusive coloring if every $u, v \epsilon E(G), w(u) \ne w(v) $ and $max (l) = min \{ max (l_i), l_i label function\}$. The chromatic number of local irregularity inclusive coloring of $G$ denoted by $\chi_{lis}^{i}$, is the minimum cardinality of local irregularity inclusive coloring. We study about the local irregularity inclusive coloring of some family tree graph and we have found the exact value of their chromatic number.

Dalam menyelesaikan persoalan matematika, terlebih yang mengintegrasikan permasalahan di kehidupan sehari hari diperlukan kemampuan metaliterasi siswa. Metaliterasi merupakan kerangka berpikir yang menyeluruh dan menjadi sumber referensi mandiri yang bersifat luas dibandingkan dengan jenis literasi lainnnya. Kemampuan metaliterasi siswa saat ini dapat dibilang rendah karena masih tergolong baru dan pembelajaran belum sepenuhnya menggunakan Internet of Things dalam pelaksanaannya. Oleh karena itu, dalam penelitian ini menggunakan model pembelajaran Research Based Learning dengan pendekatan STEM yang berfokus pada pemecahan masalah dekorasi teselasi wallpaper. Pada permasalahan ini, siswa merepresentasikan model dekorasi wallpaper kedalam bentuk titik dan garis untuk menemukan kombinasi warna yang sesuai. Selanjutnya dengan menggunakan konsep relasi fungsi, siswa dapat menemukan pola pewarnaan dari dekorasi tersebut. Dalam kegiatan pembelajaran, permasalahan STEM yang diangkat akan dikembangkan framework integrasi RBL-STEM untuk meningkatkan metaliterasi siswa. Hasil penelitian yang diperoleh berupa sintaks baru yang efektif dalam memecahkan permasalahan teselasi wallpaper dengan model RBL-STEM yang melibatkan relasi fungsi, perangkat pembelajaran RBL-STEM dan potret fase kemampuan metaliterasi siswa

The ability of metaliteracy is very important in the industrial era 4.0. Metaliteracy is a comprehensive framework of thinking that goes beyond other literacies with the main literacy being information literacy. It is indicated that the metaliteracy of students is still low, it is because this literacy is still relatively new. The use of the IoT in learning is also still uneven, including the learning model used by teachers has not been able to fully support the formation of this ability. Therefore, in this study, the Research-Based Learning model which is integrated with the STEM approach (Science, Technology, Engineering, Mathematics) will be applied to solve the STEM problem of flight scheduling. Students are introduced to the application in the form of a set of sequential pairs, then with the representation of the set of points and lines a specific schedule is drawn up and includes its generalizations. The next step is how to bring STEM problem solving in learning class, then the developed RBL and STEM tools in learning to improve students' metaliteracy. From the results of the study, it was found that the RBL device with the STEM approach developed met the valid, effective, and practice criteria.

Abstract:Indonesia is a producer of various types of fruit. Production and area of plantations tend to increase every time. However, its quality and safety still need attention. In general, the low quality of fruit is caused by postharvest management, one of which is in the packaging process. Specific temperatures and pressures will affect air circulation in the fruit packaging container. Besides, the good packaging design of containers will result in proper air circulation. The finite volume method is used to analyze air circulation in the optimization of postharvest technology based on packaging procedures. The results showed the higher the incoming air pressure, the temperature of the air formed in the packaging container would be even higher. The air holes with the up and down position help in the process of air circulation more evenly. More air holes will increase the temperature of the air inside the packaging container.Abstrak:Indonesia merupakan penghasil beragam jenis buah. Produksi dan luas pertanaman cenderung meningkat setiap waktu. Namun demikian mutu dan keamanannya masih perlu mendapat perhatian. Secara umum, rendahnya mutu buah disebabkan oleh pengelolahan pascapanen, salah satunya dalam proses pengemasan. Suhu dan tekanan tertentu akan mempengaruhi sirkulasi udara di dalam wadah kemasan buah. Selain itu, desain wadah kemasan yang baik akan mengakibatkan sirkulasi udara yang baik. Metode volume hingga digunakan untuk menganalisis sirkulasi udara dalam optimasi teknologi pascapanen buah berdasarkan prosedur pengemasan. Hasil penelitian menunjukkan semakin besar tekanan udara yang masuk maka suhu udara yang terbentuk di dalam wadah kemasan akan semakin besar. Posisi lubang udara dengan posisi atas dan bawah membantu dalam proses sirkulasi udara yang lebih merata. Semakin banyak lubang udara akan meningkatkan suhu udara di dalam wadah pengemasan.

Goal Programming is a method of solving problems by allocating company resources with several objectives to obtain an optimal solution. The solution can be obtained by using the QM for Windows program. The results showed that the objective function could be achieved well. The solution to the problem obtained from the QM For Windows application was that the optimal value for the budget cost of the window, storefront, and wardrobe raw materials was the same as the budget cost that had been issued by the furniture production owner, which was Rp. 22,850.000,00 per month. Then the upper limit can be minimized to raw material from aluminum (b1), which was 28.1 meters from the original 610 meters. In order to reach the target of the production process, the average working hours was 55 hours. For a good and correct production volume recommendation, the number of products produced must be optimal to produce 20 units of products consisting of 10 units of windows, five units of show windows, and five wardrobe units per month.
