Evaluation of Public Involvement in the Formulation of Local Government Work Plans in Langkat Regency
type: item
description: Community participation in the preparation of the Local Government Work Plan (RKPD) is an important aspect in realizing transparent and accountable governance. This research aims to involve the level of community involvement in the preparation of the RKPD in Langkat Regency and identify the obstacles and opportunities faced in this participatory process. The method used is a qualitative approach with interview, observation, and documentation study techniques to obtain comprehensive data. The results of the study show that despite the existence of formal mechanisms such as the Development Planning Conference (Musrenbang), public involvement is still relatively low due to limited access to information, low transparency, lack of use of digital technology, and low capacity of apparatus in facilitating participatory discussions. In addition, people tend to be passive in making proposals because they feel that their aspirations are rarely accommodated in the final policy. Therefore, this study recommends increasing socialization and education, the use of digital technology in Musrenbang, increasing the capacity of apparatus, and strengthening civil society in the planning process. With these steps, it is hoped that public participation in the preparation of the RKPD can be more optimal, so that the resulting policies are more in line with the needs of the community.

Settlement Patterns and Availability of Environmental Infrastructure in Flood-Prone Areas along the Bingai Riverbanks: A Study on Community Risk and Resilience
type: item
description: Flooding is a recurring disaster in the riverbank areas of the Bingai River, Binjai, North Sumatra, largely influenced by settlement patterns and inadequate environmental infrastructure. This study aims to analyze the relationship between settlement patterns and the availability of environmental infrastructure with the level of risk and community resilience in facing flood disasters. Using a qualitative descriptive method with a SWOT analysis approach, the research involved 100 respondents, consisting of 80 residents and 20 business actors affected by flooding. The findings indicate a relatively strong sense of community, with 85% of residents actively participating in communal work (gotong royong), and 78% having developed survival strategies. However, 90% of residents face challenges related to micro-infrastructure, such as poor drainage systems and a lack of evacuation routes. Additionally, 73% of resident experience limited access to disaster mitigation information, resulting in low community preparedness for flood events. In terms of opportunities, 50% of the community has begun utilizing local technology, while 60% of business actors have adapted more resilient business models in response to flooding. Key challenges include changes in river flow patterns caused by human activity (88%) and increased migration to riverbank areas (60%), both of which could elevate future flood risks. Based on these findings, several strategic recommendations are proposed, including the enhancement of flood-adaptive micro-infrastructure, community education on disaster mitigation, the development of environmentally based economic models, and more sustainable settlement management. Through the implementation of these strategies, it is expected that communities along the Bingai Riverbanks will be better prepared to face floods and build stronger resilience systems against environmental changes.

Utilization of Soil Moisture Sensor as an Early Warning of Drought in Plants with Arduino Microcontroller
type: item
description: Drought in plants is one of the common problems that often occurs, especially in potted plants that are indoors and completely dependent on manual watering by the owner. This research aims to design and implement a soil drought early warning system using a soil moisture sensor (FC-28) integrated with an Arduino UNO microcontroller. The system is designed to read the soil moisture level in real-time and provide visual notification through a 5 mm LED indicator. The method used includes designing an electronic circuit consisting of a moisture sensor, Arduino, LED, and other supporting components. The FC-28 sensor detects soil moisture and sends an analog signal to the Arduino for processing. If the moisture value is lower than a predetermined threshold, the Arduino will activate the LED as a sign that the soil is dry. Tests were conducted on three types of planting media (loose soil, clay, and husk mixture) in three different moisture conditions (wet, humid, and dry). The test results show that the system can detect drought conditions with consistent accuracy across different types of growing media. The system is effective as a simple monitoring solution that is easy to apply for household-scale plant monitoring. In addition, the system has the potential to be further developed towards watering automation and integration with the Internet of Things (IoT).

3-Phase Electrical Power Factor Improvement Simulator System Design Based on Automatic Control
type: item
description: This research aims to design and test a three-phase power factor improvement simulator based on Power Factor Controller (PFC) to improve power efficiency in industrial electrical systems. This simulator is equipped with two modes of operation, namely manual and automatic, and uses a capacitor bank to improve the power factor. Tests were conducted with two types of loads, namely resistive loads (light bulbs) and inductive loads (three-phase induction motors). The test results showed that in manual mode, the gradual addition of capacitors succeeded in increasing the power factor from 0.22 to 0.71. While in automatic mode, the power factor reached 0.73, although slightly lower than the desired set point value (0.85). This improvement in power factor has the effect of reducing reactive power consumption and operating costs. This research proves that the use of a Power Factor Controller can improve energy efficiency and reduce operational costs in three-phase induction motor-based electrical systems. Further development can involve the use of capacitors with smaller capacities and the integration of IoT-based monitoring systems for performance optimization.

Based on the results of the measurements that have been made, it is found that the low voltage value in the Dusun Nangka area is 170 volts against the one-phase source voltage to neutral (226 V) and occurs during peak loads or in other words the voltage drop. According to SPLN 1: 1995, the service line voltage tolerance (SP) is + 5% of the standard low voltage stress at the base side and -10% at the end side. At 19.00 when there is a peak load, consumers cannot make electronic devices such as water pumps, refrigerators, air conditioners and others. With such conditions, it is necessary to simulate ETAP 12.6.0 to make improvements, namely the construction of an in-line transformer and uprating the HUTR 3x35mm2 + 1x25mm2 to 3x70mm2 + 1x50mm2 in that area. For this reason, several assumptions are made, namely direct measurement calculations and simulations so that the low voltage value in the area is 219 Volts.

Grounding System With Top Grounding Method on Overhead Transmission Lines of Langsa - Lhokseumawe
type: item
description: Continuity of electricity distribution is the most important thing in the industrial sector. A momentary disruption in distribution can cause significant losses. This is certainly a challenge so that the electricity supply is always available in any condition. One way that can be done to overcome the increase in excess current in the channel due to lightning strikes is by installing grounding with the Top Grounding method. It is known that the overhead transmission lines of Langsa - Lhokseumawe is one of the radial backbone lines of the Aceh system. Based on the disturbance in the first semester of 2024, there have been 4 lightning strikes on this line. This is certainly a small number, but every year there are always lightning strikes that cause equipment trips. The consequences are very significant because they can disrupt the optimization of the Arun PLTMG and Nagan Raya PLTU. Furthermore, if these two power plants are not ready when the Langsa - Lhokseumawe SUTT trip occurs, the Aceh system could enter a Black Out condition or total blackout. The factors that influence the determination of the location point for placing Top Grounding are based on the tower that is most often struck by lightning and including the resistance of the soil around the tower. Before being implemented, this system was simulated using the ATP Draw application.

Analysis of the Soiling System on Peatland at the Distribution Substation of PT PLN (Persero) ULP Bagan Siapi Api
type: item
description: The grounding system is an important component in the reliability and safety of the electric power distribution system. This study aims to analyze the performance of the grounding system at the distribution substation owned by PT. PLN (Persero) ULP Bagan Siapi Api, especially on peatland. The data collection method was carried out by measuring the grounding resistance using the Fall-of-Potential method with a Digital Earth Tester. The study was conducted on two types of soil, namely peatland and barren land, to compare their resistance values. The measurement results showed that peatland has a very low resistance, with an average of 1.25 Ω using a single electrode (single rod), far below the maximum limit set by the 2011 PUIL standard of 5 Ω. Meanwhile, the barren land showed a high resistance (14.30 Ω) which could only be reduced to meet the standard by adding electrodes in parallel. These findings conclude that the peatland in the Bagan Siapi Api area actually supports an effective and efficient grounding system, contrary to the general assumption that peatland has a high resistance. These results can be the basis for making technical policies for installing grounding systems in similar areas.

type: item
description: The use of induction motors in industrial applications continues to grow due to their robustness, low cost, and minimal maintenance requirements. However, maintaining optimal performance under varying load conditions remains a challenge. This research aims to analyze the performance of an induction motor control system that integrates a Variable Frequency Drive (VFD) and a Neural Network-based controller to improve efficiency and dynamic response under different load variations. The VFD serves as a tool to regulate the motor’s frequency and voltage, enabling precise speed control. Meanwhile, the neural network algorithm is designed to learn and adapt in real time, adjusting control parameters according to load conditions to maintain stability and efficiency. Experimental tests were conducted by applying different load scenarios to the induction motor and recording key parameters such as motor speed, torque, current, and efficiency. The results showed that the integration of the neural network with the VFD enhanced the system's adaptability and performance, especially during sudden changes in load. Compared to traditional PID control, the proposed system provided faster response times, better energy utilization, and improved motor protection. This study demonstrates that a hybrid control system combining VFD and neural networks offers a promising solution for modern motor control systems requiring intelligent and adaptive behavior.

Analysis of Drop Voltage in Low Voltage Network (JTR) 380/220 Volt Distribution Substation of PT PLN (Persero) ULP Tanah Jawa
type: item
description: One of the reliability requirements of the electric power distribution system that must be met for service to consumers is good and stable voltage quality. Most loads have a lagging power factor and basically at peak load times, the reactive power required by the load increases and can be greater than that generated by the system. Voltage changes are basically caused by the relationship between voltage and reactive power. The voltage drop across a conductor is proportional to the reactive power flowing across the conductor. Within ± 2 years (2022-2024), the addition of a significant load to the distribution substation, especially PT PLN (Persero) Tanah Jawa, does not take into account the cross-sectional area of the conductor. This has an impact on consumers, where there is a difference between the initial voltage (220 V) and the final voltage (211 V) with a conductor length of ± 1.95 km, the voltage regulation that occurs in the house connection of this channel is 1.6%. The results of the load flow calculation using 25 mm2 and 16 mm2 AAAC cable channels, there is a voltage drop of 2.86÷3.52 Volts on all buses, the voltage regulation for all buses is above 1%. Based on (SPLN No. 56-1, 1993), the allowable voltage drop tolerance at the house connection (SR) is 1% of the nominal voltage, thus all nodes or buses have exceeded the maximum allowable tolerance limit. The results of the power flow calculation (load flow) after replacement using 35 mm2 AAAC and 25 mm2 SR channel cables, there is a voltage drop of 0.22÷0.3 Volts on all buses, the voltage regulation for all buses is below 1%

DVOR & DME Building Power Network Monitoring Labuan Bajo Sub-Branch Uses Telegram API Bot Notifications Through Netwatch Mikrotik
type: item
description: The development of information technology in tandem with the flow of globalization has brought major changes to the way humans access and disseminate information. One of the impacts is to make the internet a primary need, both in the world of work, education, and government. Easy access and instant communication are indispensable in the management of information systems, especially in network infrastructure monitoring. Telegram is one of the cloud-based instant messaging applications that is open source. The app not only offers basic communication features, but it also supports the development of advanced functions through the Telegram Bot API. This feature allows developers to create automation systems, including in terms of network monitoring. On the other hand, Netwatch is one of the features of the Mikrotik RB2011UiAS-RM device that functions to monitor network connections to certain destination addresses on a regular basis. When a connection interruption occurs, Netwatch may take automated actions, such as sending notifications or executing certain scripts. By combining Netwatch and Telegram's Bot API, a network monitoring system can be built to provide real-time notifications to network administrators. One of the implementations of this system was carried out at the DVOR & DME Building of the Labuan Bajo Sub-Branch which is located on a hill, about 500 meters to the north of the Tower Building. Access to the location is quite difficult because it is not equipped with street lighting, has rocky and steep terrain, and can only be passed by two-wheeled vehicles, especially during the rainy season. In these conditions, a network monitoring system that is able to provide up/down internet status information directly through Telegram is very important. This notification can be an indicator of whether the power grid at the location is still active or has been out, so that technicians can respond faster without having to check directly to the location.

However, the main challenge in its implementation is the ability to adapt to a dynamic and unstructured work environment. This study aims to analyze the development of an artificial intelligence-based (AI)-based control algorithm on robot manipulators, with an initial approach using the inverse kinematics (IK) method, Pixy2 visual sensor, and PID control. The system was tested in a controlled environment and showed an average position error of only 1–4 mm, with relatively low and stable power consumption. However, this approach still relies on static environmental conditions and system parameters that must be calculated manually. To improve flexibility and adaptability, the Deep Reinforcement Learning (DRL) method was identified as a more advanced AI solution. DRLs allow the system to learn from experience and respond to environmental changes autonomously, but with the consequent greater power requirements due to high computing loads and dynamic motor control. The results of the analysis show that the integration of DRLs can improve the intelligence and independence of manipulator robots, but requires more complex electrical system planning and energy management. In conclusion, the IK approach is suitable for systems with limited resources and structured environments, while DRLs are more suitable for dynamic and complex industrial scenarios with adequate power infrastructure support.

Wireless Sensor Network Performance Analysis for Indoor Air Quality Monitoring
type: item
description: Air pollution involves physical, chemical, and biological substances that can harm health and cause disease in living beings. Therefore, understanding air quality is very important. This research aims to design and develop a prototype of a web-based air quality monitoring system using Wireless Sensor Network (WSN) technology. Communication between the client and the server uses WebSocket.io protocols to reduce latency in the network. The system design is divided into two parts: the design of the server hardware and software, the microcontroller, as well as the user client interface. The study involves evaluating key performance metrics such as data reliability, latency, and power efficiency. Various sensor nodes are used to measure parameters including temperature, humidity, volatile organic compounds (VOCs), and particulate matter (PM). The nodes communicate with the central coordinator nodes, forming a mesh network topology to ensure reliable data transmission and coverage. The results of the performance analysis demonstrate the effectiveness of WSN in providing accurate and timely indoor air quality (IAQ) data. Challenges such as signal interference and node placement optimization are addressed to improve network reliability and coverage. The insights gained from this study contribute to the development of a more efficient IAQ monitoring system, encourage a healthier indoor environment and improve overall well-being.

Design and Build a Solar Panel-Based Water Level Detection Device with LED Indicator and Buzzer
type: item
description: The electrical system in Kenari Hamlet is supplied by the PR 072 distribution transformer through PU.08 feeders. The PR 072 transformer is located on Jalan Melati, Desa Melati II with a capacity of 160 kVA which is used to supply electricity to the Dusun Nangka area. Based on the results of the measurements that have been made, it is found that the low voltage value in the Dusun Nangka area is 170 volts against the one-phase source voltage to neutral (226 V) and occurs during peak loads or in other words the voltage drop. According to SPLN 1: 1995, the service line voltage tolerance (SP) is + 5% of the standard low voltage stress at the base side and -10% at the end side. At 19.00 when there is a peak load, consumers cannot make electronic devices such as water pumps, refrigerators, air conditioners and others. With such conditions, it is necessary to simulate ETAP 12.6.0 to make improvements, namely the construction of an in-line transformer and uprating the HUTR 3x35mm2 + 1x25mm2 to 3x70mm2 + 1x50mm2 in that area. For this reason, several assumptions are made, namely direct measurement calculations and simulations so that the low voltage value in the area is 219 Volts.

Evaluation of Information Technology Governance Using the Cobit 5 Framework at Putra Abadi University Langkat
type: item
description: Information Technology (IT) governance plays an important role because IT is now not only a supporting factor, but also a strategic element in improving efficiency and supporting the achievement of organizational goals. Universitas Putra Abadi Langkat (UNIPAL) has utilized various IT-based systems such as Academic Information Systems and E-Learning to support the institution's main processes. However, the results of interviews indicate challenges in the implementation and oversight of IT, insufficient optimization of resources, and an imbalance between investment costs and the results obtained. This study aims to assess the level of IT governance capability at UNIPAL using the COBIT 5 framework because this framework emphasizes resource optimization, in line with institutional needs. The evaluation was conducted on 16 relevant COBIT 5 domains, including EDM02, EDM04, APO01, APO07, BAI01, DSS01, and MEA01. The analysis results show that all domains are at Level 1 (Partially Achieved), except for APO01, which reaches the Largely Achieved category, although overall it remains at Level 1. The average capability level obtained is 0.30315 (30.315%). Although basic practices (Base Practice) are mostly running well, evidence of documentation (Work Product) is generally not available. The expected target is Level 2, resulting in a gap of 1.69685. Therefore, it is recommended that UNIPAL strengthen documentation, establish formal policies, and improve IT oversight and utilization to achieve a more optimal level of capability.

Analysis of Electrical Energy Consumption Due to the Influence of Passenger Weight on the Medan Fair Plaza Elevator
type: item
description: An elevator is a mechanical device designed to facilitate vertical transportation of people or goods between floors within a building. This system operates automatically through a drive motor and specific control mechanisms, enabling time and energy efficiency in multi-story structures. This study aims to evaluate the extent to which passenger load influences the power and electrical energy consumption of the elevator drive motor at Plaza Medan Fair, particularly when operated at 0%, 50%, and 100% of its maximum load capacity. The method applied in this research involved direct data collection on-site. Observations revealed that under no-load conditions (0 kg), the power required for upward movement reached 4.62 kW, with a total energy usage of 55.44 kWh over a 12-hour period. At 50% load (approximately 525 kg), the power increased to 7.61 kW, and energy consumption rose to 91.32 kWh. At full load (±1050 kg), the elevator consumed 8.21 kW. During downward movement, the elevator with no load consumed 5.51 kW of power and 66.12 kWh of energy. With a 50% load, the power used was 7.12 kW and energy consumption reached 85.44 kWh. At full capacity during descent, power consumption was recorded at 7.34 kW with 88.08 kWh of energy used.These findings confirm that variations in passenger load significantly affect both the power demand and energy usage of the elevator’s drive motor. Therefore, regular maintenance and performance checks are essential to ensure the lift operates efficiently and reliably.

Repair of Donggo Feeder Voltage with the Power Evacuation Method to the Substation at PT. PLN (Persero) ULP Woha
type: item
description: In the distribution network, there is one problem, namely the rating capacity that exceeds the feeder load and the length of the feeder. This will cause the current distributed by a conductor to be greater and the distance of the load served is too far so that it can cause power losses and voltage drops to customers. One way to overcome the problem of overloading the feeder is to perform power evacuation. Based on the results of the study, it shows that at PT. PLN (Persero) the Donggo Feeder experienced a voltage drop at the end voltage. One of the causes of the end voltage drop is the length of the electrical system circuit from the source. One solution to this problem is to perform power evacuation. In this case, the working principle of power evacuation is to build a new feeder to increase the voltage. By carrying out this power evacuation, it has a good impact on improving the end voltage at the feeder load, where the end voltage drop must follow the standard, namely a minimum limit of +5% and -10% set by PT. PLN (Persero) in the standard voltage (SPLN No. 72,1987).

Design and Build an Automatic Chair Wheel Control System with Microcontroller-Based Arduino Flex Sensors
type: item
description: This research aims to design and build an automatic chair wheel control system that can help improve the independence and mobility of people with disabilities. The system uses an Arduino Uno R3 microcontroller as the control center, as well as a joystick and flex sensor as motion command inputs. Other key components include a 24V DC motor, a driver motor, an I2C LCD, and a 24V 30Ah lithium-ion battery as a power source. The system is designed to respond to gesture commands such as forward, backward, left turn, right turn, and stop based on input from the user. The test results showed that the system successfully recognized the direction of movement through the signal from the joystick, controlled the DC motor in the direction, and displayed the motion status information in real-time on the LCD. The whole system works well, is responsive, and synchronous. Thus, this system can be an effective, economical, and applicative auxiliary technology solution for wheelchair users. Further development can be directed at the addition of security sensor features and body movement-based control (flex sensor).

Implementation and Analysis of PID Control System Visually GeoGebra-Based
type: item
description: PID (Proportional-Integral-Derivative) control systems are a control method that is widely used in various engineering applications because of its ability to maintain stability and improve system performance. However, understanding the working mechanism of PID is often challenging, especially for learners or users without a strong control background. This study aims to implement and visually analyze the PID control system using GeoGebra software. Through interactive modeling, each controlling component (proportional, integral, and derivative) is visualized separately to show the influence of each on the system's response. In addition, the GeoGebra construction protocol is leveraged to construct dynamic simulations that allow users to adjust PID parameters directly. The results of the study show that GeoGebra is effectively used as a learning and exploration medium for the concept of the PID control system, as well as facilitating the process of visually tuning parameters. Thus, this approach can be an intuitive educational alternative to understanding and analyzing the PID control system.
