Abstract

This research aims to apply military mathematical models in decision making for security crisis management in DKI Jakarta Province. This research departs from the urgent need to deal with crime problems and improve regional security. Regression model is used to analyze the relationship between independent variables (Pure Participation Rate, Unemployment, Gini Index, and GRDP) and dependent variable (Criminal Risk). Historical and current data on security, education, employment, income inequality, and the economy were collected for analysis. The results show that Net Enrolment Rate and Unemployment have a negative influence on Criminal Risk, while Gini Index and GRDP have a positive influence. These findings provide a deeper understanding of the factors that contribute to the security crisis in the region. Based on the analysis results, this study concludes that the application of military mathematical models can be an important reference for the government in addressing the crime problem and improving security in DKI Jakarta Province. The proposed recommendations are to improve access to education, reduce the unemployment rate, address income inequality, and strengthen the economic sector. The implementation of integrated policies between government agencies is also considered important to achieve optimal results in overcoming the security crisis.

Abstract

IBN (National Defense Index) is an important indicator in measuring public awareness and participation in maintaining the sovereignty and stability of the country. With the increasing complexity of challenges to national resilience, a predictive approach is needed to understand the relationship between IBN and other variables that influence national resilience. The CART method is used to identify patterns and determine significant variables that play a role in strengthening national resilience. Through this model, the study aims to provide deeper insight for the formulation of more effective policies in building strong national resilience. The results of the study were obtained by identifying factors that influence the National Defense Index (IBN). The results of this study are expected to be a consideration for the basis for strategic policies in achieving the great goal of Indonesia Emas 2045 as a strong, sovereign, and sustainable country.

Abstract

This paper proposes a new model of urban security for city branding in Indonesia, which aims to address the gap in city branding indices lacking safety and security factors. The proposed model, the Urban Defense Index (UDI), measures a region's ability to manage risks and handle security threats in urban areas. The UDI is calculated based on three sub-indices: ThreatsDisruptions- Obstacles- Challenges (TDOC), Posture, and Stability, which use objective and subjective measurements. A case study uses the proposed model to measure five Kalimantan cities' urban defense readiness levels. The study found that Stability, Posture, and TDOC are essential factors in determining the level of urban defense readiness in the cities. Future research can address the limitations of the UDI model proposed in this study and expand the UDI model to include other factors that affect urban security.

Abstract

Penelitian ini menyajikan pengujian mendalam terhadap Lightweight Encryption Algorithm (LEA) pada mikrokontroler NodeMCU ESP8266. Pertama, penelitian ini mengontekstualisasikan pentingnya IoT di berbagai sektor, menggarisbawahi kebutuhan kritis akan kerahasiaan data yang kuat di tengah meningkatnya tantangan keamanan. Penelitian ini mempelajari ranah lightweight cryptography, yang menekankan perlunya solusi kriptografi yang efisien serta aman pada perangkat dengan sumber daya komputasi yang terbatas. Berfokus pada cipher LEA, penelitian ini mengevaluasi kinerjanya di berbagai ukuran kunci (128, 196, dan 256 bit) dan membandingkan kecepatan enkripsi dan dekripsinya dengan literatur yang ada. Temuan menunjukkan bahwa LEA tidak hanya memberikan pendekatan yang seimbang terhadap keamanan dan efisiensi tetapi juga beradaptasi dengan baik terhadap batasan lingkungan IoT, terutama jika dibandingkan dengan algoritme lain seperti AES-128. Penelitian ini memberikan kontribusi pada bidang keamanan IoT, menawarkan gambaran yang penting dalam implementasi solusi kriptografi di lingkungan yang memiliki keterbatasan sumber daya.
