Abstract

Leaf diseases are one of the primary factors contributing to reduced agricultural productivity, especially in tropical regions such as Indonesia. Early identification of infected areas is crucial to prevent further disease spread and minimize crop losses. This study proposes the application of YOLOv8 instance segmentation with an in-training augmentation strategy to precisely detect and segment leaf disease areas. The dataset consists of 3,528 diseased leaf images, with 588 original images used for validation and 2,940 augmented images for training. The augmentation process includes mosaic, HSV adjustment, spatial transformations, RandAugment, and other techniques to enhance the model’s generalization capability. Model performance was evaluated using mAP, precision, recall, and Intersection over Union (IoU) metrics. Experimental results demonstrate that the model achieved stable performance with high mAP@50, precision and recall approaching optimal values, and an average IoU above 0.5. This approach is effective and has strong potential for implementation in early plant disease detection systems, supporting farmers in making timely and accurate decisions.

Abstract

Indonesia has the potential for new and renewable energy (EBT), including solar energy as a source of power generation. Energy efficiency can be defined as the ratio between the electrical power generated and the input power received. Low efficiency impacts the electrical power output of solar modules. This underlies the use of Solar Power Plants (PLTS) as a new and renewable electrical energy source to replace fossil fuels that have limited quantities and pollute the environment. Solar cells as PLTS units have the constraint of insufficient output power and are highly dependent on natural conditions. One method of optimizing solar cells is by using sunlight-reflecting glass (reflectors). Sunlight is a renewable energy source that can be utilized as a new power generator. However, in the process, certain additions are required to the solar cell module to optimize the output voltage produced. Efforts to optimize electrical output in solar modules by maximizing the intensity of light falling on the surface of the solar module by using direct sunlight. The results obtained are in the form of a comparison.

Abstract

The development of electric vehicle technology continues to experience rapid progress, especially in terms of energy efficiency and power storage systems. One of the main components in an electric vehicle is the battery, which plays a crucial role in determining the vehicle's range, performance, and energy efficiency. This study aims to analyze the battery life of a BLDC (Brushless DC) motor used in a mini electric car prototype. Testing was conducted at the Electrical Engineering Laboratory of Panca Budi Development University with various load scenarios and operating times to evaluate battery life performance. The research method was carried out through an experimental approach by directly measuring voltage, current, temperature, and operating duration using a digital measuring instrument and periodically recording the data. The test results showed that the battery has optimal performance within a certain current range, but experienced a decrease in capacity as the load and operating temperature increased. From the test results, it was concluded that battery life is greatly influenced by operational conditions and charging system management. This study provides an initial overview for the development of a battery management system (BMS) and energy efficiency design in a laboratory-scale mini electric vehicle. Development recommendations are directed at temperature control and load power regulation so that the battery can be used more optimally and sustainably.

Abstract

Advertisements play a significant role in shaping gender representation through the construction of signs and visual meanings. This study is motivated by the phenomenon of shifting gender roles in the domestic sphere, as represented in the ABC Soy Sauce advertisement “Suami Sejati Mau Masak, Terima Kasih Kecap ABC” (“A Real Husband Cooks, Thanks to ABC Soy Sauce”). The research aims to analyze how the advertisement constructs, negotiates, and deconstructs the meanings of masculinity and femininity. A qualitative descriptive method is applied using Jacques Derrida’s deconstruction. The data consist of dialogues, audio narration, and visual representations of characters in the advertisement. The findings reveal that the advertisement portrays the image of a modern man who is willing to cook as an effort to challenge traditional gender dichotomies. However, it simultaneously reproduces subtle patriarchal values. Women remain positioned at the center of domestic labor through the narrative of “helping” and specific visual symbols, while gender equality is commodified through the product’s role as a mediator. The study concludes that the advertisement offers only a pseudo-deconstruction: it appears progressive on the surface but ideologically maintains patriarchal myths within the domestic sphere.

Abstract

Low grounding resistance is an important factor in ensuring the safety and reliability of electric power systems, especially on High Voltage Overhead Lines (SUTT). This study aims to analyze and improve the grounding resistance values on 150 kV SUTT towers on the Glang–Namorambe line using the three-point measurement method. Measurements were conducted to determine the actual condition of the grounding system and evaluate the effectiveness of the improvements made. Initial measurements showed that several towers had resistance values exceeding the maximum PLN standard limit of 10 ohms. To address this, improvements were made by installing additional electrodes, adding conductors, and using ground enhancement materials. After the improvements, remeasurements were conducted for each tower. The analysis results showed that the applied improvement method succeeded in reducing the grounding resistance value significantly, with an average reduction of 40–60%. The final resistance values of all towers were below the specified threshold, so that the grounding system can function properly in protecting equipment and personnel safety from overvoltage disturbances caused by lightning and ground faults.

Abstract

This study aims to optimize the performance of the distribution substation in maintaining the stability of the electricity network, especially in reducing the effects of voltage drops in the Kuta-cane Customer Service Unit (ULP). Significant voltage drops can affect the quality of electricity supply and cause instability that impacts the performance of customers' electrical equipment. This study includes data collection on distribution substations and network conditions, voltage drop measurements at critical points in the network, and voltage distribution simulations using electrical analysis software. Based on the results of the analysis, optimization of the distribution substation was carried out by adjusting the transformer capacity, installing load balancing devices, and rearranging the load distribution to reduce voltage drops. The optimization results showed an increase in voltage stability in the Kuta-cane ULP electricity network, as indicated by a decrease in voltage drops in previously problematic areas. This optimization has proven effective in maintaining distribution stability and improving the quality of electricity supply to customers. This study produces technical recommendations that can be implemented by the Kutacane ULP in maintaining the performance of distribution substations sustainably, so as to improve the reliability of the electricity network in the region.

Abstract

Environmental management and village cleanliness through social movements in community empowerment efforts in Sei Nagalawan Village, Perbaungan District, Serdang Bedagai Regency, are still constrained by various factors. These include: the limited capacity of the village community to reduce the rapidly increasing volume of waste, the low level of community knowledge regarding waste management and household yard cleanliness, and weak partnerships in community-based waste management initiatives. This situation needs to be addressed through community service programs. The activities are designed to empower the PKK (Family Welfare Movement) Women’s Group, village Posyandu (Integrated Health Post) cadres, and the broader community by providing outreach and awareness-raising on the importance of maintaining a clean, waste-free environment through social movements. The objectives of this independent community service program are to: (1) contribute to reducing the alarming rate of waste generation, (2) increase the knowledge of PKK members and Posyandu cadres on waste management, and (3) strengthen local institutions as a means of fostering community-based social movements for waste management. The methods used in this program include: socialization and training on environmental management with a focus on preventing yard waste, and a participatory approach to social movements that integrates the role of local institutions. The results of this community service initiative demonstrate increased community motivation to manage waste and maintain clean household yards through social movement-based approaches.

Abstract

This study aims to analyze the implementation of the HIV/AIDS prevention policy at the Kedungwaringin Community Health Center (Puskesmas), Bekasi Regency, based on the Van Meter and Van Horn policy implementation model, which includes six variables: policy standards and objectives, resources, inter-organizational communication, implementing characteristics, socio-economic-political conditions, and implementers’ disposition. The research employed a descriptive qualitative method, with data collected through in-depth interviews with program managers, health workers, and PLWHA (People Living with HIV/AIDS). The results show that the implementation of the policy has a clear legal basis and standard operating procedures (SOPs), but they are not yet fully understood by all implementers, particularly cadres who have not received further training. Limited human resources, operational funds, and training are the main obstacles to program effectiveness. Vertical communication with the Health Office functions well through the SIHA 2.1 application, but horizontal communication with village authorities, NGOs, and the community remains suboptimal. In addition, social stigma against PLWHA and economic barriers among the community hinder sustainable access to health services. Program implementers’ motivation tends to decline due to high workloads, lack of incentives, and insufficient supervision. In conclusion, the implementation of the HIV/AIDS prevention policy at the Kedungwaringin Community Health Center has been carried out but is not yet optimal. Strengthening human resource capacity, regional budget support, cross-sectoral coordination, and educational and inclusive approaches are needed to reduce stigma and expand service coverage. Support from all stakeholders is essential for the policy to be implemented effectively and sustainably.

Abstract

This study analyzes the implementation of the Bedas Digital Service (BDS) policy system at the Population and Civil Registration Office (Disdukcapil) of Bandung Regency using the Van Meter and Van Horn (1975) model. BDS was launched as a response to weaknesses in the manual system for monitoring and supervising population administration services. This qualitative research, employing a single case study design, utilized in-depth interviews, participatory observation, and document analysis. Data were analyzed using Miles and Huberman’s interactive model, along with source and method triangulation. The findings show that BDS implementation achieved 75% of its target. Based on the six variables of the Van Meter and Van Horn model: the policy standards are clear, emphasizing efficiency, monitoring, and transparency; resources are supported by the regional budget (APBD) and free WiFi in 280 locations, although human resources remain limited (only 10 IT operators); vertical and horizontal communication runs effectively; Disdukcapil possesses adequate competence; the environmental conditions show strong political support but digital gaps persist among adult and elderly groups; and implementers’ dispositions are positive. Supporting factors include political backing, competent human resources, WiFi infrastructure, inter-agency coordination, and adoption by younger generations. Inhibiting factors involve server instability, limited personnel, digital divides, dependence on central systems, geographical blank spots, and cautious behavior among staff. BDS has successfully reduced illegal intermediaries, improved transparency (trust index rising from 65% to 88%), and increased time efficiency (from several months to 2–3 days). The one-day service target has not been fully achieved due to technical and operational challenges. Overall, BDS implementation shows significant progress but still requires infrastructure strengthening, additional personnel, and digital literacy programs for optimal outcomes.
