9. BITCOIN AS A SYSTEM THAT RESISTS RECOVERY A NON-LINEAR SYSTEM DESIGN STUDY ON SCARCITY AND SECURITY
This study aims to structurally examine why loss of access to Bitcoin is permanent and to assess claims regarding the possibility of recovery, master keys, or backdoors in the Bitcoin system. This study departs from the general trend that positions Bitcoin solely as a monetary innovation, while its most radical aspect lies in its system design. Bitcoin is analyzed as a non-linear formal system that defines ownership through cryptographic facts, rather than through identity, intent, or social context. The methodology used is a conceptual-design analysis based on cryptographic studies, protocol architecture, empirical precedents of human error, and the implications of network consensus. The main results demonstrate that irreversibility and loss of access are not system failures, but rather direct consequences of Bitcoin's design axioms, which tie ownership to high-entropy private keys and reject all forms of discretionary authority. The analysis also shows that claims of backdoors, whether mathematical, implemental, hardware, or temporal, are structurally incoherent without undermining the fundamental assumptions of cryptography and decentralized consensus. The study's conclusions affirm that Bitcoin's resilience stems not from adaptive flexibility but from deliberate rule rigidity. This research's contribution lies in mapping Bitcoin as a system design artifact that resists recovery, while also expanding the Bitcoin discourse from the monetary realm to the study of system design, applied cryptography, and the philosophy of technology.

8. OPERATIONS RESEARCH MODEL IN CONVENTIONAL MILITARY DECISION-MAKING
This study aims to analyze the robustness and risk of military decisions through the application of an operations research model based on sensitivity analysis. Conventional military decision-making has historically relied on doctrine, experience, and the intuition of commanders. This approach is adaptive, but has limitations in testing the resilience of military decisions to changes in strategic and operational parameters. The research methodology uses a quantitative approach with operations research modeling and sensitivity testing for key parameters such as time, cost, and risk. The main results indicate that military decisions based on operations research models have a more consistent level of robustness than conventional approaches. The study's conclusions confirm that operations research models play an effective role as objective and measurable military decision-support systems. This research contributes to strengthening the systems and decision science approaches in the study of conventional military decisionmaking.
7. DOCTRINE TESTING FROM A COMPLEX SYSTEMS PERSPECTIVE CONVENTIONAL VERSUS CONTEMPORARY APPROACHES IN THE AXIOM-BASED DOCTRINE TESTING MODEL AND SYSTEM RESILIENCE
This study aims to methodologically analyze the limitations of conventional doc trine testing approaches and compare them with contemporary complex systems-based approaches, using doctrinal axioms and system resilience as the basis for evaluation. Operational doctrine is traditionally tested through conventional approaches that emphasize normative compliance, historical precedent, and limited scenario-based simulations. This approach is based on the assumption of strategic and operational environmental stability and the linearity of cause-and-effect relationships. However, the dynamics of contemporary strategic and operational environments which are non-linear, adaptive, and produce emergent effects demonstrate a methodological gap between the reality of the system encountered and the doctrine testing mechanisms employed. The study uses a conceptual qualitative approach through a systemic-doctrinal analysis with a comparative method of epistemic assumptions, testing logic, and validity criteria of both approaches. The analysis shows that the conventional approach is prone to pseudo-validity because it assesses doctrine primarily based on procedural compliance, rather than systemic resilience to environmental change and operational disruption. In contrast, the contemporary approach offers a more structurally consistent evaluation framework in addressing the complexity of the strategic and operational environment. Therefore, doctrine testing needs to be reoriented from a normative verification model to a complex systems-based evaluation model as a structural methodological necessity. This research contributes to the development of a doctrine evaluation methodology that is more relevant to the study of contemporary defense doctrine and strategy.
6. PROPOSED DESIGN OF AN ACTIVE FIRE PROTECTION SYSTEM BASED ON K3 USING ALARM DETECTORS AND SPRINKLERS IN THE WORKING AREA OF AIR SQUADRON 17, HALIM PERDANAKUSUMA AIR BASE
This research aims to develop a design proposal for an alarm detector and sprinkler system in the workspace of Air Squadron 17 at Halim Perdanakusuma Air Force Base. Aircraft hangars are work facilities with a high fire risk due to aircraft maintenance activities, the use of technical equipment, the storage of chemicals, and the presence of flammable materials. From an Industrial Engineering perspective, these conditions require the design of a safe, reliable, and sustainable work system through the application of Occupational Safety and Health (OHS) principles. One effective fire risk control measure is the implementation of an active fire protection system in the form of automatic alarm detectors and sprinklers. The research methods used included identifying potential fire hazards, analyzing fire protection system requirements, calculating the number and placement of alarm detectors and sprinklers based on applicable standards, as well as designing pipelines and summarizing material requirements. References used in the design included the NFPA 13 standard and national regulations related to OHS and fire protection. The results of the study indicate that the proposed alarm detector and sprinkler system design is capable of providing optimal fire protection throughout the hangar workspace. This design is expected to improve personnel safety, protect strategic assets, and support the operational continuity of Air Squadron 17. Furthermore, the results of this study can serve as a technical reference in designing fire protection systems in similar work facilities.
5. EXPERIMENTAL FIGHTER AIRCRAFT GROUND MANEUVER SIMULATION
This study aims to explore and analyze various factors that affect ground maneuvers on fighter aircraft, focusing on the steering system and landing gear design. Fighter aircraft, as a major component in military operations, must not only have optimal air maneuverability, but also be able to maneuver on the ground effectively and efficiently. The ability to move quickly and precisely on the ground is essential. Precise ground maneuvers not only ensure the safety of the aircraft, but also affect operational efficiency and response time in dealing with emergency situations. In this study, simulations were conducted using a mathematical model developed in MATLAB/Simulink software to model and analyze aircraft movements during the ground operation phase. This model considers various important parameters such as aircraft speed, nose landing gear deflection, and weight distribution settings to obtain more accurate results. The results of this simulation show that changes in the nose landing gear deflection affect aircraft movements, including the ability to change direction with a smaller radius and shorter time. Thus, the results of this study are expected to provide new insights into fighter aircraft design to improve ground maneuver performance and improve fighter aircraft operational efficiency in various field conditions.
4. ECONOMIC ASYMMETRY IN DRONE WARFARE A CASE STUDY OF IRAN'S SHAHED-136 OPERATION AGAINST ISRAEL'S IRON DOME DEFENSE SYSTEM
The advent of low-cost loitering munitions has revolutionized modern warfare, creating a profound economic imbalance between offensive and defensive capabilities. In the Middle East, the deployment of Iran's Shahed-136 drone against Israel's Iron Dome defense system serves as a prime example of a "cost-imposing" strategy in asymmetric warfare. Objective: This study aims to quantify the economic disproportion between the production and deployment costs of the Shahed-136 drone and the operational costs of the Iron Dome system. It explores how this cost ratio impacts long-term national defense budgets and strategic sustainability. Methodology: This study uses a qualitative-descriptive approach supported by comparative economic modelling. Data are synthesized from defense budget reports, estimates of the Shahed-136 manufacturing costs, and the unit cost of the Iron Dome Tamir interceptor missile. The analysis uses the Cost-Exchange Ratio (CER) to evaluate the economic efficiency of both sides. Results: The study's findings reveal a sharp economic asymmetry, with a single Shahed-136 estimated to cost between $20,000 and $50,000, depending on configuration, while a single Tamir interceptor missile costs approximately $40,000 to $100,000, depending on configuration. When factoring in "saturation attacks" (or drone swarms), defense costs increase exponentially, not only through missile expenditure but also through the economic disruption caused by airstrike warnings and collateral infrastructure damage if interceptions fail. Conclusion: The study concludes that while Iron Dome remains tactically effective in saving lives, its current economic trajectory is unsustainable against the threat of low-cost, mass-produced drones. The study suggests that to maintain strategic stability, the defense framework must transition to lower-cost interception technologies, such as directed energy weapons (lasers/Iron Beam), to neutralize the economic advantage currently held by offensive drone platforms.
3. AIRPORT EMERGENCY DIESEL PREVENTIVE MAINTENANCE MANAGEMENT USING BATTERY INTERNAL RESISTANCE MONITORING ANALYSIS
Emergency diesel generator is a very important system in every industry including the airport industry because this system supports the electricity of important equipment when a blackout occurs. in the emergency diesel generator system, there is a battery as a starter for the diesel engine. if the battery capacity decreases, the diesel generator will not be able to start the engine, therefore in the emergency diesel generator system, regular battery maintenance is needed to maintain system reliability. in this journal, preventive maintenance on the battery will be explained, especially on the emergency diesel generator system battery. one indicator of decreased capacity in the battery is an increase in its internal resistance value. in preventive battery maintenance, analyzing the increase in internal resistance can be a reference for replacing a new battery.

The study concluded that transitioning to Structural Health Monitoring technology and fleet modernization are crucial risk mitigation measures for the global air cargo industry.
1. THE ROLE OF AIR POLICING IN ACHIEVING AIR SUPERIORITY: AN ANALYSIS WITH NATO AIR POLICING CASE STUDY
Air policing serves as a critical mechanism for maintaining airspace integrity within nations or alliances, directly contributing to air superiority in military defense contexts. This paper analyzes the role of air policing in establishing and sustaining air dominance, focusing on the NATO Air Policing case study. Employing qualitative and quantitative approaches, including literature review, historical data, statistical tables, and graphs, we explore how air policing functions as deterrence, rapid response, and a foundation for broader military operations. The NATO case since 2004 demonstrates over 300 annual interceptions in recent periods, reinforcing alliance solidarity and preventing conflict escalation. In-depth analysis, enhanced by Analytic Hierarchy Process (AHP) for prioritizing factors, Monte Carlo simulations for risk assessment, and relevant theories such as deterrence theory and air power theory, reveals air policing as a strategic element supporting modern military doctrines where air superiority is prerequisite for ground and naval operations. Findings emphasize the integration of advanced technologies like radar and fifth-generation fighters to enhance effectiveness. This paper concludes that air policing is a foundational pillar for air superiority, with implications for global defense policies in geopolitical tensions.
7. A COMPARATIVE ANALYSIS OF SPUKTA REGULATIONS: A STUDY OF VLOS OPERATIONAL PROCEDURES IN CONTROLLED AIRSPACE BETWEEN THE FAA, EASA, AND DGCA INDONESIA
This study aims to critically analyze and compare the SPUKTA VLOS operational procedure framework in the Control Area established by three major aviation authorities: the Federal Aviation Administration (FAA), the European Union Aviation Safety Agency (EASA), and the Directorate General of Civil Aviation (DGCA) Indonesia. The integration of Small Unmanned Aircraft Systems (SPUKTA) or drones into civil airspace, particularly in the Control Area (CTR), requires strict and uniform operational procedures. The most common Visual Line of Sight (VLOS) operations pose a high risk in controlled airspace if not properly regulated. Using a descriptive qualitative method with comparative content analysis of primary regulatory documents (FAA Part 107, EASA Reg. (EU) 2019/947, pm 37 of 2020 and PM 63 of 2021/CASR Part 107 Indonesia), the comparison focuses on five key procedural variables: Operational Clearance Mechanism, Operational Altitude Limit, Pilot Communication Requirements, Time Window Provisions, and Pre-flight Procedures. The results show that while the FAA and EASA offer mature systems (automated LAANC vs. risk-based Geozone), the Indonesian DGCA relies on manual permitting processes and local authority discretion. This disparity indicates a gap in regional automation and standardization. This study recommends that the Indonesian DGCA consider implementing a real-time authorization system and digital Geozone to improve compliance and efficiency of VLOS SPUKTA operations in the Control Area.
6. INCREASING LARGE-SCALE AGRICULTURAL EFFICIENCYWITH THE DJI AGRAS T25 DRONE: A CASE STUDY IN CILEGON

The variables measured are time efficiency, labor effi ciency, water efficiency, operational costs, and crop productivity during one planting season. The results show that the use of drones can save 85% of time and reduce operational labor costs per watering session, with yields that are not statistically significantly different. The operational efficiency offered by drones makes this method superior for the sustainability and profitability of large-scale agriculture
2. CYBER VULNERABILITY MITIGATION IN WI-FI NETWORKS: INTEGRATION OF PENETRATION TESTING, SOCIAL ENGINEERING, AND SECURITY AWARENESS IN XYZ EDUCATIONAL INSTITUTION
This study aims to empirically and comprehensively assess security vulnerabilities in military Wi-Fi networks at the XYZ defense educational institution, encompassing technical aspects (penetration testing with Aircrack-ng, WPA2 encryption analysis) and human factors (social engineering, personnel security awareness). A convergent mixed-methods approach was used to integrate quantitative and qualitative data. Penetration testing conducted at four strategic locations revealed that 75 percent of the network could be breached in less than 130 minutes due to weak passwords with low entropy (less than 60 bits) and default configurations. Meanwhile, a survey of 50 personnel showed that 80 percent were unable to accurately identify phishing attacks before training, and 65 percent were vulnerable to pretexting scenarios. Vulnerability analysis using the CIA Triad framework revealed violations of Confidentiality (40 percent of traffic could be intercepted within 30m), Integrity (20 percent of the network was vulnerable to Man-in-the-Middle), and Availability (DoS through deauthentication closed 80 percent of active sessions). hese findings indicate that the human factor is the biggest vulnerability (95 percent of global cyber breaches originate from human error or manipulation). Therefore, mitigation recommendations are integrative and multi-layered, encompassing technical interventions (migration to WPA3 with SAE, implementation of RADIUS and Snort IDS), behavioral interventions (regular awareness training and monthly phishing simulations), and organizational interventions (establishment of a 24/7 CSOC). This integrated framework is estimated to reduce attack success by 70 percent, which is crucial for creating military cyber resilience in accordance with the spirit of Sishankamrata and Permenhan No. 82/2014 concerning Cyber Defense.
1. DEGREE OF SUPERIORITY IN AIR OPERATIONS THEORETICAL ANALYSIS, DETERMINING FACTORS, AND STRATEGIC CASE STUDY
This study aims to analyze the degree of air superiority, a strategic concept that plays a central role in the planning and implementation of modern air operations. This term refers to the degree of control of an air force over a specific area that allows the execution of missions without significant interference from opposing air forces. In general, the degree of air superiority is classified into three categories: air parity, air superiority, and air supremacy, each of which indicates a different degree of dominance over potential enemy air threats. Air dominance is a strategic prerequisite that determines the outcome of modern conflicts. The concept of degree of superiority evolves along with changes in technology, doctrine, and the complexity of global geopolitics. In the context of air operations, achieving degree of air superiority is influenced by various factors, including technological capabilities, the effectiveness of air defense systems, information mastery, and the efficiency of command, control, communications, computers, intelligence, reconnaissance, and surveillance (C4ISR) systems. The interaction of these factors contributes to the success of joint operations and the ability to maintain long-term air dominance. Effective air superiority also directly impacts the freedom of action of one's own forces in conducting cross-service operations. A comprehensive understanding of the degree of air superiority is a key factor in strategic decision-making at the operational level. Integration of technological capabilities, information superiority, and cross-service coordination is necessary to achieve sustainable air dominance. Therefore, analyzing the degree of air superiority is not only crucial for tactical purposes but also serves as the basis for developing comprehensive air defense doctrine and strategy. This article discusses the theoretical framework in depth, the factors influencing its achievement, and presents case studies from various conflicts ranging from World War II to potential conflicts in the Indo-Pacific. This study confirms that successfully achieving air superiority depends not only on air power alone, but also on multi-domain integration, defense industry readiness, and political and diplomatic support.
9. STRATEGIES, CHALLENGES, AND IMPLEMENTATION OF GENDER EQUALITY IN THE POLICE
This study aims to analyze the implementation of gender mainstreaming policies within the Indonesian National Police (Polri) and identify challenges and gaps in their implementation. This study uses a qualitative approach with descriptive analysis methods to evaluate how the Indonesian National Police (Polri) has integrated gender equality principles into its operations and human resource policies, including policy documents, internal reports, and interviews with Polri personnel. The results indicate that although the Polri has demonstrated its commitment to gender mainstreaming through the issuance of Police Chief Regulation Number 1 of 2022, its implementation remains suboptimal. Significant disparities exist between male and female police officers in recruitment, promotion, and job placement. Female police officers (Polwan) often face certain limitations not experienced by male police officers (Polki), such as specific recruitment criteria and a lack of opportunities for open promotions. Consequently, the majority of female police officers remain confined to administrative and health roles, with few reaching senior leadership positions.

This study aimed to analyze the causes of sensor failure at PT GMF AeroAsia Tbk. The methodology used was observation, interviews, and document analysis. Data were analyzed using Pareto charts and Fault Tree Analysis to identify the root cause. The results indicated that corrosion was the primary cause, exacerbated by environmental factors, weak inspection procedures, and a lack of technician understanding. In conclusion, the sensor failure was caused by a combination of technical, procedural, and human factors. This research helps develop better aircraft maintenance strategies to improve safety.
3. APU STARTER MOTOR RELIABILITY ANALYSIS P/N 2704506 – 4 AIRBUS A320S USING WEIBULL DISTRIBUTION AND FAILURE MODE AND EFFECT ANALYSIS AT PT INDONESIA AIRASIA
This study aims to determine the reliability value and failure characteristics of the APU starter motor P/N 2704506-4, as well as to identify the failure mode qualitatively to provide improvement recommendations for PT Indonesia AirAsia. The starter motor in the auxiliary power unit (APU) is a vital component that functions to start the operating cycle. The method used is a mixed method, with quantitative analysis through processing historical time to failure data from 20 unscheduled removal cases using the Weibull distribution, and qualitative analysis through failure mode and effect analysis. Data were obtained from the Aircraft Maintenance Manual, Component Maintenance Manual, and semi-structured interviews with engineers. The analysis results show a value of β = 2.029 (β>1) which indicates a wear-out failure pattern. The scale parameter η recorded 3,095.71 flight hours with a mean time to failure of 2,742.85 hours. Reliability projections show that at 2,800 hours, reliability drops to 44.23% with a failure probability of 55.77%. The FMEA analysis identified three failure modes: brush wear, terminal winding burn, and oil contamination. Of these, brush wear was the dominant failure mode, with 12 cases and the highest RPN value (252). The study concluded that starter motor failure is predictive and dominated by brush wear. The primary recommendation is to transition to a preventive maintenance strategy through visual inspection of brush wear indicators and scheduled replacement at 2,500–2,600 flight hours to reduce unscheduled removals and increase aircraft availability.
5. WEATHER RADAR SYSTEM FAILURE ANALYSIS ON AN AIRBUS 320-200 AIRCRAFT AT PT GMF AEROASIA USING FMEA AND RCA TO IMPROVE RELIABILITY AND SAFETY
This study aims to analyze the failure of the Weather Radar System using a mixed-methods sequential explanatory approach. Flight safety is highly dependent on the reliability of avionics systems, one of which is the Weather Radar System that functions to detect extreme weather phenomena. Damage to this system is categorized as a no-go item in the MEL and based on data from the Top Delay Report of PT GMF Aero Asia Tbk for the period 2020–2024, it ranks fifth as the highest cause of delays on the Airbus A320-200, with 341 failure reports. The quantitative stage uses Failure Mode and Effects Analysis (FMEA) and Pareto Diagrams to identify critical components, while the qualitative stage uses Root Cause Analysis (RCA) and Fishbone Diagrams to explore the root causes of failure. The results show that the Transceiver is the most problematic component with 39% of unscheduled removals with the dominant failure mode being Intermittent Signal with an RPN value of 336. RCA reveals the main causal factors including human error, non-compliance with procedures, limited tools, low material quality, and exposure to extreme environments. Recommendations for improvement include improving technician competency, tool procurement and calibration, stringent material vendor selection, and system protection from extreme weather. This research is expected to support increased maintenance effectiveness, reduce delays, and strengthen the safety culture at GMF.

8. DESAIN PERANCANGAN LOWCOST VIBRATION SENSOR UNTUK PEMANTAUAN KONDISI BEARING PADA SISTEM ROTASI ANTENA RADAR
Penelitian ini bertujuan untuk mendeteksi getaran bearing dalam mendukung kegiatan pemeliharaan berkelanjutan secara real-time, sebagai alternatif penggunaan sensor. Kinerja sistem radar sangat bergantung pada beberapa faktor, salah satunya pada fungsi mekanik yang bertumpu pada bearing untuk menopang antenna saat berputar. Adanya gangguan pada rotasi yang dapat disebabkan oleh kondisi bearing yang tidak baik akan menurunkan performa kinerja radar, bahkan dapat menyebabkan kegiatan operasional sistem berhenti secara keseluruhan. Oleh karenanya, pemantauan kondisi bearing menjadi hal penting untuk mendeteksi secara dini gejala kerusakan melalui analisis getaran dengan menggunakan sensor getaran. Penelitian ini menawarkan solusi low cost vibration sensor berbasis Arduino Nano dengan memanfaatkan akselerometer ADXL345 untuk mendeteksi getaran bearing dalam mendukung kegiatan pemeliharaan berkelanjutan secara real-time, sebagai alternatif penggunaan sensor getaran komersial yang mahal. Melalui desain perangkat keras berupa Arduino Nano dan sensor ADXL345, dilakukan pemrograman sistem untuk akuisisi data getaran, serta analisis data dalam domain waktu dan frekuensi menggunakan Fast Fourier Transform (FFT). Sensor tersebut diuji pada bearing antena radar di salah satu satuan radar TNI AU, sehingga hasilnya dapat mensimulasikan baik kondisi normal, tidak seimbang (unbalance) maupun misalignment. Hasil eksperimen menunjukkan bahwa dengan analisa yang tepat dan teliti menggunakan software Matlab, sistem mampu membedakan pola getaran antara kondisi normal dan abnormal dengan akurasi cukup baik. Kontribusi utama penelitian ini adalah pengembangan sistem sensor getaran yang efisien dengan harga terjangkau, mudah dibawa (portable) dan efektif diimplementasikan untuk pemantauan kondisi bearing pada sistem rotasi radar dengan harapan dapat menjadi dasar pengembangan sensor pada penerapan Condition Based Maintenance (CBM) untuk mendukung operasional radar.

Secara garis besar bekerjanya SSR seperti halnya sistem komunikasi (elektronik) point-to-point antara Interrogator (yang berada di darat), dengan mengirimkan Mode signal, pada frekuensi 1030 MHz, dan Transponder (yang ada di pesawat udara) yang mengirimkan Code signal pada frekuensi 1090 MHz sebagai respon. (Interrogator requires an airborne Transponder on the airplane which responds to the receipt of pulses from a ground-based antenna; This response signal (CODE) can contain much more information, e.g. an altitude, an identification code or also any technical problems on board such as a radio contact loss, etc.)
5. ANALISIS PENJADWALAN ULANG PROYEK RUMAH SUSUN TIGA LANTAI DI AKADEMI ANGKATAN LAUT (AAL) SURABAYA DENGAN MENGGUNAKAN METODE PERT
Penelitian ini bertujuan untuk memberikan gambaran proses pembangunan rumah susun bertingkat. Proyek pembangunan rumah susun tiga lantai di kota X mengalami masalah keterlambatan dibandingkan dengan jadwal yang telah ditetapkan. Kekurangan sumber daya alam menjadi salah satu penyebab keterlambatan proyek ini. Keterlambatan pasokan material mengakibatkan banyaknya pekerja yang menunggu. P enelitian ini menggunakan metode CPM (Critical Path Method) dan PERT (Program Evaluation Review Technique) untuk merencanakan, menjadwalkan, dan mengendalikan proyek. Pendekatan tersebut digunakan untuk menentukan lintasan, mengidentifikasi aktivitas penting, menghitung durasi, dan memperkirakan waktu penyelesaian. Hasil analisis menunjukkan bahwa jadwal awal adalah 411 hari dan progres saat ini adalah 72% atau sekitar 296 hari, setelah dilakukan perhitungan ulang terdapat 12 aktivitas kritis yang terlewati, sehingga proyek diperkirakan selesai dalam waktu 306 hari. Penjadwalan awal yang terlalu optimis perlu dilakukan penyesuaian. Jam kerja proyek adalah pukul 08.00 WIB sampai dengan 17.00 WIB setiap hari. Penelitian ini menyarankan agar dilakukan penjadwalan ulang agar proyek selesai tepat waktu dan efisien.
Penelitian ini dilaksanakan bertujuan untuk mendeteksi pesawat terbang yang sedang mendekat dari jarak 40 mil (sekitar 64 km). Radar primer atau Primary Surveillance Radar (PSR) termasuk jenis radar aktif dengan respon pasif, dan merupakan radar konvensional yang memancarkan signal gelombang elektromagnetik terarah ke ruang udara dan menerima serta mengolah signal gelombang elektromagnetik yang dipantulkan (echo signal) dari sasaran (objek) yang umumnya bersifat logam. Radar primer tidak memerlukan peralatan tertentu pada sasaran (objek), berbeda dengan radar sekunder (SSR) yang memerlukan peralatan tertentu pada sasaran (objek) yang disebut transponder. Radar (PSR) ini menggunakan system antena yang berputar baik secara mekanik maupun elektronik untuk memindai (scanning) ruang udara dengan cakupan (coverage) 360 derajat (360o ) azimuth. Radar ini dapat memberikan informasi jarak, azimuth, kecepatan, dan ketinggian (elevasi) sasaran (objek) baik yang bergerak maupun sasaran yang diam. Selain itu, radar primer memerlukan daya pancar yang kuat untuk dapat menjangkau sasaran (objek) yang jaraknya jauh (ratusan NM).
