PERTANGGUNGJAWABAN NEGARA DALAM KEBOCORAN DATA PADA PLATFORM E-GOVERNMENT: ANALISIS HUKUM ADMINISTRASI ATAS KASUS SATU SEHAT DAN DPMPTSP ONLINE
Data breaches on digital public service platforms represent a critical phenomenon that tests the commitment of a constitutional state. This study analyzes state accountability under administrative law regarding data breach incidents on E-Government platforms, using case studies of Satu Sehat and DPMPTSP Online. The research employs a normative juridical method through case study and document analysis approaches. The findings indicate that although the legal framework for state accountability has been established under the Personal Data Protection Law (UU PDP) and its implementing regulations, its implementation has not fully realized the principle of legal certainty. The state’s responsibility as the data controller remains hindered by regulatory disparities, limited cybersecurity capacity, and incident response mechanisms that are slow and lack transparency. Forms of accountability that should be procedural and predictable such as the obligation of 72-hour notification, proportional administrative sanctions, and civil lawsuit mechanisms through the State Administrative Court (PTUN) are still not optimal in practice. This study concludes that strengthening state accountability requires regulatory harmonization, enhanced institutional capacity of the Personal Data Protection Authority (OPDP) and the National Cyber and Crypto Agency (BSSN), and standardized incident response protocols. Policy recommendations are directed toward reinforcing state accountability in protecting citizens' personal data in the digital sphere.

Pengaruh Lingkungan Kerja Fisik Dan Gaji Terhadap Kinerja Karyawan Pada KSP Credit Union Bererod Gratia Pusat Jakarta Timur
Abstract This study aims to analyze the influence of the Physical Work Environment and Salary on Employee Performance, both partially and simultaneously, at KSP Credit Union Bererod Gratia East Jakarta Center. The research background is based on the condition of the physical work environment that still requires improvement in several aspects and a relatively uniform salary structure that does not fully consider the workload and responsibilities of each position. The type of research used is associative quantitative with a survey method. The research population consisted of all 60 permanent employees, all of whom were used as the sample (census). Data was collected through a Likert scale 1-5 questionnaire and analyzed using multiple linear regression analysis with the help of SPSS 27 software. The hypothesis testing results show that: (1) Partially, the Physical Work Environment has no significant effect on Employee Performance (sig. 0.801 > 0.05). (2) Partially, Salary has a positive and significant effect on Employee Performance (sig. 0.001 < 0.05). (3) Simultaneously, the Physical Work Environment and Salary together have a positive and significant effect on Employee Performance (F sig. 0.000 < 0.05) with a contribution of 35.4% (R Square = 0.354). Based on these findings, it is concluded that although the physical work environment is not yet the main individual driver, the combination of improving the quality of the physical work environment and a fair and competitive salary system is an effective strategy for improving employee performance. The suggestions provided are that management needs to review the salary structure based on workload and responsibilities, as well as periodically maintain and improve physical work environment facilities, while still paying attention to other non-financial factors that influence performance.

Analisis Tegangan Output Dan Tegangan Diode Penyearah Jembatan Gelombang Penuh 1 Phase Menggunakan MATLAB SIMULINK
A rectifier is a power electronics circuit that functions to convert alternating current (AC) voltage into direct current (DC) voltage required by various electronic devices. This study aims to analyze the characteristics of the output voltage and the voltage across the diodes in a single-phase full-wave bridge rectifier circuit using MATLAB Simulink software. The research method used is a simulation method by designing a circuit model consisting of an AC voltage source, four diodes arranged as a bridge rectifier, a load, and a filter capacitor. The simulation results show that the input voltage has a sinusoidal waveform with a peak value of approximately 120 V. After the rectification process, the output voltage becomes a pulsating DC voltage with a peak value of about 93 V, which is influenced by the voltage drop across the diodes. The addition of a filter capacitor is able to reduce the voltage ripple, resulting in a more stable load voltage in the range of 84 V to 87 V. The results of this study indicate that the full-wave bridge rectifier circuit is capable of converting AC voltage into DC voltage effectively, and MATLAB Simulink simulation can be used as an effective analysis tool for studying the characteristics of power electronics circuits before implementation in real systems.

The system uses several key parameters, namely pH, temperature, turbidity, and Total Dissolved Solids (TDS), which at the design stage are simulated using a potentiometer. Data from the sensors is processed by the ESP32 through an analogue-to-digital conversion process, then displayed in real-time on a 16×2 LCD and potentially sent to an Internet of Things (IoT) based platform. The design results indicate that the system is able to read and display data accurately according to input changes, and operates according to the designed algorithm. This system has advantages in terms of efficiency, ease of development, as well as multi-parameter monitoring capability. Thus, the designed system can serve as an alternative solution for more effective water quality monitoring and has the potential to be developed into an IoT-based remote monitoring system.
Implementasi Smart Integrated Garden Light Berbasis IoT: Sistem Penerangan Adaptif dengan Monitoring Mikroklimat dan Kualitas Udara untuk Area Terbuka Hijau
Conventional lighting systems in green open spaces, such as city parks and residential gardens, predominantly rely on manual controls or static timers. This conventional approach often leads to significant electrical energy waste, as the lights continuously operate at maximum intensity regardless of the presence of visitors or activity in the area. In addition, the increasingly urgent issue of environmental pollution necessitates the availability of microclimate monitoring data that the public can easily access prior to engaging in outdoor activities. This research aims to design and implement an Internet of Things (IoT)-based Smart Integrated Garden Light prototype as an intelligent solution that integrates energy efficiency with an environmental monitoring station. The prototype utilizes the ESP32 DevKit V1 microcontroller as the central processing unit, interfaced with four primary sensors: a Light Dependent Resistor (LDR) to detect day and night ambient lighting conditions, a Passive Infrared (PIR) sensor to detect visitor movements, a DHT11 sensor for temperature and humidity monitoring, and an MQ-135 sensor to detect fluctuations in harmful gases (air quality). The methodology employed includes literature review, hardware and software design using a multitasking approach in the Arduino IDE, physical assembly, and functional testing scenarios. Through this design, the system is expected to significantly reduce energy consumption by implementing an adaptive lighting mechanism (dimming), wherein the light will operate in a dim state (standby mode) when the park is empty at night, and automatically switch to full brightness upon detecting visitor presence. Furthermore, the system is designed to transmit microclimate parameter data continuously and in real-time to a cloud platform via the Blynk application, allowing users to transparently access environmental information using a smartphone. It is concluded that this innovation has the potential to transform garden lamp posts from mere conventional lighting devices into intelligent infrastructures (smart nodes) that support security, energy efficiency, and a sustainable Smart City concept
