Abstract

Penelitian ini bertujuan untuk menemukan rute perjalanan kendaraan pengangkut sampah di Kota Yogyakarta. Manfaat penelitian ini yaitu sebagai bahan evaluasi serta pertimbangan dalam pemilihan rute alternatif pengangkutan sampah Kota Yogyakarta. Menggunakan metode dengan perpaduan ilmu matematika secara teori, logika pemikiran, dan ilmu komputasi dengan mengambil lokasi penelitian di Sektor Gunung Ketur yang merupakan bagian dari tanggung jawab Dinas Lingkungan Hidup Kota Yogyakarta. Teori yang digunakan yaitu penggunaan graf berupa graf berbobot dan berarah. Sedangkan algoritma yang digunakan yaitu Cheapest Insertion Heuristic (CIH) yang merupakan bagian dari algoritma Insertion dengan modifikasi Route Construction (RC) yang merupakan salah satu dari metode algoritma Artificial Immune System (AIS). Dengan demikian, penerapan ilmu matematika secara teori dan diperkuat komputasi dapat diterapkan secara nyata. Permasalahan penentuan jalur tercepat maupun efektivitas suatu perjalanan sebenarnya tidak memiliki suatu solusi yang pasti. Tentunya setiap metode memiliki pendekatan masing-masing. Namun, yang perlu diperhatikan adalah kepastian langkah yang digunakan agar langkah tersebut dapat menghasilkan output yang sama meskipun menggunakan metode pendekatan yang berbeda. Hasil yang diperoleh pun sebenarnya tidak sepenuhnya sempurna tetapi hanya menghasilkan beberapa solusi ataupun pilihan yang dapat dijadikan bahan pertimbangan untuk menyelesaikan suatu permasalahan. [This research aims to find the route of the garbage truck in Yogyakarta City. The benefit of this research is to produce the evaluation and the consideration of the selection of alternative routes for transporting the waste in Yogyakarta City. The research has been done by combining theoretical mathematical science, logic, and computational science by focusing on solving the problem at Gunung Ketur Sector, which is under the Environmental Agency of Yogyakarta City. The research used the theory of weighted and directed graphs. Furthermore, the researchers used the Cheapest Insertion Heuristic (CIH), which is a part of the Insertion algorithm with a modified Route Construction (RC), which is one of the methods of Artificial Immune System (AIS) algorithm. Therefore, the application of theoretical mathematical science and computationally could be applied in a real problem. Indeed, the determination of the fastest and the most effective routes has no concrete solutions. Each method has its own approach. However, it is crucial to consider the certainty of the procedure used to produce the same output even though using different ways. The result obtained is not entirely perfect, but the research outcome has made some solutions or alternatives as considerations to solve a problem.]

Abstract

The extent to which adolescents are able to recognize and understand their emotions determines their ability to manage emotions. This community service discusses the socialization of psychoeducation as an early intervention in adolescent emotion management. Adolescents in orphanages who have not been able to recognize the various emotions they have need attention, because this can affect the way they manage emotions, thus having a negative impact on the learning process. Therefore, this service program is focused on psychoeducation related to the recognition of emotions, the function of emotions, the kinds of emotions, the application of emotions, and how to manage emotions, and express emotions properly. The method used includes the PAR (Participatory Action Research) method by involving active participation from the community or research subjects in every stage, from problem identification to implementation and evaluation. The results of the community service showed that the psychoeducational socialization activities related to adolescent emotional management consisted of a pre-test, two sessions of material (i.e., session 1 on the socialization of the seminar on self-awareness of emotions, and session 2 on the delivery of material on how to manage emotions and express emotions appropriately), and concluded with a post-test related to emotional management. In addition, there was a significant increase in understanding of emotions and how to manage them. The psychoeducational socialization activities helped adolescents in the orphanage to better recognize their feelings and learn how to express them appropriately. This program contributes to shaping the next generation of a superior and noble nation. Psychoeducation can also be an initial solution for adolescent emotion management and can be applied in other orphanages.
