Hierarchical clustering for crime rate mapping in Indonesia

Abstract

The Sustainable Development Goals (SDGs) are a blueprint for improving the human life quality. Goal 16 (G16) is related to security, and it is in line with the Universal Declaration of Human Rights and the Preamble to the 1945 Constitution. To support the implementation of the G16 achievement, the Indonesian National Police (Polri) has made serious efforts to provide a sense of safety for the community and to minimize crime rates. One of the efforts that could be made is to map areas based on the level of crimes so that the Polri can determine the appropriate strategy/priority of action for mitigation. Therefore, this study aimed to cluster provinces in Indonesia based on the four G16 indicators of the SDGs related to security, namely the number of homicide cases, the victim proportion, the proportion of people who feel safe walking alone in the area where they live, and the proportion of victims of violence that reported to the police in the past year using five hierarchical clustering methods, namely: Single-Linkage, Average-Linkage, Complete-Linkage, Ward, and Division Analysis. Then, methods were validated and compared using six cluster validations to obtain the most compact method. The results showed that Ward's method outperformed the others and produced three clusters. Clusters 1, 2, and 3 contained 18, 5, and 11 provinces respectively.

“…Untuk itu 193 negara termasuk Indonesia yang tergabung sebagai anggota PBB menyepakati agenda pembangunan berkelanjutan yang disebut sebagai Tujuan Pembangunan Berkelanjutan (Sustainable Development Goals/SDG's) sebagai upaya penyelesaian polemik yang belum terselesaikan dari agenda pembangunan sebelumnya. Pemerintah Indonesia berkomitmen dalam pelaksanaan agenda SDG's ini salah satunya dengan menerbitkan Peraturan Presiden (Perpres) nomor 59 tahun 2017 tentang pelaksanaan pencapaian agenda SDG's (Rendra, dkk, 2022). Dengan adanya Perpres ini seluruh provinsi di Indoensia ikut serta dalam pelaksanaan agenda SDG's ini termasuk Provinsi Sumatera Barat.…”

Toddlers’ Nutritional Status Prediction Using the Multinomial Logistics Regression Method

“…Outliers, duplicate data, and null data are removed from the dataset. Boxplot diagrams are used to identify outliers (Gustriansyah et al, 2022b), while Histograms are used to determine each variable's normal distribution. If the amount of data for each class on the target variable (toddler status) is not balanced, the modest amount of data in the class will serve as the foundation for regulation.…”
