Abstract

The extent of national waters is a challenge for the government in efforts to secure marine areas from unlawful acts. Indonesia needs to really monitor the most vulnerable areas so that the national fish resources can be enjoyed by the community. To do this, bases for surveillance ships (KKP, Bakamla, TNI AL) need to be built in the area. One of the efforts that need to be done is to increase strict government supervision by increasing security as well as developing appropriate rules in order to prevent violations of the law. the ability of the Navy and the National Police to guard the entire sea area, they must use coastal surveillance radar. This pulse radar has electromagnetic waves that are disconnected rhythmically, and has only one antenna that is used to transmit and receive signals. To send and receive signals, these radars need a splitter called a duplexer. The duplexer serves to isolate the transmitted signal and the received signal and the main component of the duplexer is the Branch-Line Hybrid Coupler. Couplers have parameters that indicate performance such as: Return Loss, Power Coupling, Insertion Loss and insulation value. In this study, a study was conducted to determine the effect of dimensional changes on the insulation value of the Branch line coupler. Isolation is very important because it affects the performance of the duplexer. The smaller the value the better the performance of the duplexer. This research was conducted by modifying the length and width of the impedance Coupler line. Branch-Line Coupler designed. in the form of microstrips and fabricated using FR-4 substrate which has a dielectric constant of 4.6, a thickness of 1.3 mm, and an operating frequency of 3 GHz. To get the optimal value for isolation characteristics, the impedance channel must be modified, namely the length and width of the arm series (Z0 = 50 ), the length and width of the arm series (Z0 = 35.35 ), and the length and width of the shunt arm (Z0 = 50 ). The isolation optimization result is -67,786 dB.

Abstract

Global environmental issues, particularly the energy crisis and climate change, require an active and sustainable educational response. Early Childhood Education (ECE) plays a crucial role in fostering environmental awareness and shaping values and understanding of renewable energy from an early age. In coastal areas like Pangandaran, Indonesia—which has abundant potential for environmentally friendly energy sources such as solar, wind, and biomass—it is essential for communities to begin utilizing these resources sustainably. However, the implementation of this concept in ECE settings remains limited, mainly due to inadequate facilities and a lack of suitable teaching methods. As a strategic measure, the Ministry of Education, Culture, Research, and Technology (Kemendikbudristek), through the Education Standards, Curriculum, and Assessment Agency (BSKAP), issued a regulation in 2023 mandating the integration of climate change issues into curricula at all educational levels, including ECE. This policy also supports teacher training programs to enable structured teaching of green energy topics. The main challenge lies in delivering complex material in a way that aligns with the developmental stage of early childhood, which is characterized by exploration and emotional learning. This study explores the effectiveness of a digital-based approach in supporting ECE teachers in Pangandaran by utilizing platforms such as Google Spaces and Learning Management Systems (LMS). This approach is designed to help teachers present renewable energy concepts in a fun, interactive, and age-appropriate manner, thereby enhancing both teachers' and students' understanding and active engagement with environmental issues.

Abstract

The development of Internet of Things (IoT) technology has accelerated the development of Smart City, where efficient and real-time communication infrastructure is considered a very important aspect here. Mobile Ad-hoc Networks (MANETs) and Vehicular Ad-hoc Networks (VANETs) topologies offer flexible and adaptive communication models that can respond to dynamic mobility for changes in topology conditions. Generally MANETs are used for pedestrians and stationary sensors, while VANETs are used for vehicles. This study will use both topologies to be simulated for their use if applied in the development of smart cities. In this study, the feasibility and reliability of both topologies, both MANET and VANET will be tested by evaluating performance in terms of Packet Delivery Ratio (PDR) for data transmission reliability, delay (latency) for information timeliness, and throughput for data transfer capacity, which is done using NS-3 as its simulator. The number of nodes used varies from 10 - 100 for each MANET and VANET topology. Simulation results consistently show that networks using both topologies can provide superior performance. The results of this research show that combining the strengths of MANET and VANET is very suitable for future smart city applications. With its ability to provide reliable and efficient communications in highly dynamic urban environments, this technology is one of the promising solutions for building a robust and responsive communication system.
