Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in regional economic development; however, many face challenges in integrating local cultural identity, sustainability, and digital transformation into their business practices. This study develops FoSSEI LOKALITA, an MSME empowerment model that integrates local wisdom, sustainability, digital transformation, and multi-actor collaboration to enhance MSME resilience and competitiveness in Medan City, Indonesia. The study adopts an applied participatory approach by combining Design-Based Research (DBR) and Research and Development (R&D) methods. Data were collected through literature review, observation, interviews, focus group discussions, questionnaires, and expert validation. The findings indicate that although 80% of MSMEs incorporate local cultural elements into their products, 60% have not consistently communicated their cultural identity, 65% lack systematic financial records, and only 18% utilize digital marketplaces. In response, FoSSEI LOKALITAproposes a four-stage empowerment framework comprising local potential identification, capacity building, digitalization and product innovation, and pentahelix-based collaboration and replication. The model positions local wisdom as a strategic source of innovation, sustainability as a governance principle, and digital transformation as a catalyst for market adaptation. This study contributes by introducing an integrated empowerment framework that connects enterprise capacity development with collaborative ecosystem strengthening. The proposed model provides practical guidance for policymakers and development agencies in promoting sustainable, culturally rooted, and digitally enabled MSME development, while offering a foundation for future empirical validation.

Abstract

The decline in soil quality due to the continuous use of inorganic fertilizers is one of the main obstacles in increasing corn (Zea mays L.) productivity. The use of organic materials such as rice husk charcoal and goat manure organic fertilizer is an alternative to improve the physical, chemical, and biological properties of the soil so as to increase plant growth and yield. This study aims to analyze the effect of rice husk charcoal and goat manure organic fertilizer on the growth and production of corn plants and to evaluate the response of the two treatments. The study was conducted in Klambir Lima Village, Sunggal District, Deli Serdang Regency, North Sumatra, using a factorial Randomized Block Design (RBD) with two factors and three replications. The first factor was rice husk charcoal consisting of three levels, namely A₀ (0 kg/plot), A₁ (2 kg/plot), and A₂ (4 kg/plot), while the second factor was organic goat manure fertilizer consisting of four levels, namely K₀ (0 kg/plot), K₁ (2 kg/plot), K₂ (4 kg/plot), and K₃ (6 kg/plot). Data were analyzed using analysis of variance (ANOVA) and continued with Duncan's Multiple Range Test (DMRT) at a significance level of 5%. The results showed that the administration of rice husk charcoal and organic goat manure fertilizer had a very significant effect on plant height, stem diameter, number of cobs per sample, number of cobs per plot, and cob weight per plot. The treatment of rice husk charcoal dose of 4 kg/plot (A₂) and organic goat manure fertilizer dose of 6 kg/plot (K₃) gave the best results in all observation parameters. The interaction of the two treatments did not show a significant effect. The use of rice husk charcoal and organic goat manure fertilizer has been proven to increase the growth and production of corn plants and has the potential to be applied as a cultivation technology that supports a sustainable agricultural system.

Abstract

Rose plants (Rosa damascena) are ornamental plants that have high aesthetic and economic value and are widely cultivated through cutting techniques. The success of cutting growth is greatly influenced by the availability of nutrients. This study aims to determine the effectiveness of providing cow manure and liquid organic fertilizer (POC) from banana peels on the growth of rose cuttings. The study was conducted on the land of Panca Budi Development University, Sampe Cita Village, Deli Serdang Regency, North Sumatra province, from October 2025 to January 2026. The study used a 4x4 factorial Randomized Block Design (RBD) with 3 replications. The first factor was cow manure (T) consisting of T0 = 0 g/polybag, T1 = 1,000 g/polybag, T2 = 1,500 g/polybag, and T3 = 2,000 g/polybag. The second factor was banana peel POC (K) consisting of K0 = 0 ml/L water/plot, K1 = 150 ml/L water/plot, K2 = 300 ml/L water/plot, and K3 = 450 ml/L water/plot. The parameters observed included plant height, number of branches, number of shoots, number of leaves, leaf length, and stem diameter. The results showed that the application of cow manure had a significant to very significant effect on all observed parameters, while banana peel POC had a significant effect on several parameters. The interaction between the two treatments did not show a significant effect on all growth parameters. The best treatment was the application of cow manure at a dose of T3 = 2,000 g/polybag and banana peel POC K3 = 450 ml/L water/plot.

Abstract

Okra is a plant that has many benefits and nutritional content contained in its fruit. The purpose of this study was to determine the response of goat manure and liquid organic fertilizer from agricultural waste on the growth and production of okra plants. This study used a Factorial Randomized Block Design (RAK) consisting of 2 treatment factors, 16 treatment combinations and 3 blocks so that the total number of plots was 48 research treatment plots. Factor I was goat manure (K) which consisted of 4 treatment levels, namely K0 = 0 g/plot, K1 = 600 g/plot, K2 = 1200 g/plot, and K3 = 1800 g/plot. Factor II was agricultural waste POC (L) which consisted of 4 treatment levels, namely L0 = 0 ml/liter of water/plot, L1 = 15 ml/liter of water/plot, L2 = 30 ml/liter of water/plot, and L3 = 45 ml/liter of water/plot. The results of the study with the provision of goat manure on the growth and production of okra plants provided a very significant response from all observation parameters. The best level was found in the K3 treatment. The application of agricultural waste POC to okra plant growth and production showed no significant response across all observed parameters. However, the number of leaves at 4 weeks post-planting showed a significant response. The best level was found in the L1 treatment.

Abstract

The reliability of the electricity distribution network and the implementation of Occupational Safety and Health (K3L) are crucial factors in maintaining the continuity of electricity supply and minimizing the risk of work accidents. This study aims to analyze the risk management of electrical network disruptions at PT PLN (Persero) ULP. The trading period of July–December 2025 used the Failure Mode and Effect Analysis (FMEA), Hazard Identification, Risk Assessment and Risk Control (HIRARC), and Integrated Risk Framework (IRF) methods. Data were collected through field observations, structured interviews, and documentation of disruption reports. The Risk Priority Number (RPN) value was calculated based on the parameters of Severity, Occurrence, and Detection, while the K3L Risk Rating (RR) was obtained from the multiplication of Severity and Likelihood. The results showed that the Short/Flashover Transformer had the highest Integrated Risk Index value of 3150 with the Critical category, followed by Broken Lightning Arrester (IRI=2940) and Broken HUTM Cable (IRI=2400) in the High Risk category. The integration of FMEA and HIRARC through the IRF approach has been proven to provide a more comprehensive basis for risk-based decision-making than using a single method, while strengthening the K3L management system and systematically improving the reliability of the distribution system.

Abstract

The reliability of the electric power system is greatly influenced by the system's ability to maintain the loading of the main equipment within safe limits during a disturbance. In the Sumbagselteng system, conductor disturbances have the potential to cause excessive loads on the Inter Bus Transformer (IBT) due to the concentration of generation in the South Sumatra region. Therefore, the implementation of the Over Generation Shedding (OGS) scheme is required as part of the defense scheme to protect the IBT from overloading conditions. This study aims to analyze the effectiveness of the OGS scheme in limiting the fault current and improving the dynamic stability of the system. The method used is a dynamic simulation using DigSILENT software with a short circuit fault scenario and a two-stage generator shedding based on definite time characteristics. The parameters analyzed include the IBT current, loading percentage, rotor angle, logarithmic decrement, and damping ratio. The simulation results show that the IBT current increases to around 1800 A with a loading reaching 110–133% during the disturbance. After the 340 MW generator shedding in two stages, the current drops to around 490 A and the loading returns below 65%. The damping ratio ranged from 0.017 to 0.069, indicating the system remained stable with improved damping. The OGS scheme proved effective in reducing IBT loading and improving system stability under disturbance conditions.

Abstract

This study aims to analyze the verification process of temperature transmitters in control systems using the 4–20 mA linear current method. Temperature transmitters are a critical component in industrial instrumentation systems, converting temperature signals from sensors into analog current signals that can be processed by the control system. The accuracy of the transmitter output signal significantly impacts the performance of the process control system. The research method used is a verification method with a calibration approach and testing the linear relationship between the input resistance and the transmitter output current. Testing is carried out by varying the resistance value at several measurement points, then comparing the resulting output current value with the theoretical current value in the 4–20 mA range. The measurement data are then analyzed to determine the error value, percentage deviation, and linearity characteristics of the transmitter. Thus, the linear current method can be used as an effective approach in the process of verifying the performance of temperature transmitters in industrial control systems.

Abstract

Electrical energy losses in distribution systems are one indicator of the efficiency of electricity transmission. One factor influencing the magnitude of technical energy losses is changes in conductor temperature, which cause an increase in conductor resistance. This study aims to analyze the effect of conductor temperature on energy loss in the LA-03 feeder of PT. PLN (Persero) ULP Langsa. The research method used is quantitative analysis with a mathematical calculation approach based on the relationship between conductor temperature, electrical resistance, power losses, and energy loss. The data used includes a feeder length of 6.72 km, A3CS/AAAC conductor type, resistance at a reference temperature of 20°C of 0.3 Ω/km, an average load current of 150 A, a temperature coefficient of 0.004/°C, and an operating time of 24 hours. Calculations were performed at temperatures of 20°C, 40°C, and 60°C. The analysis results show that an increase in conductor temperature from 20°C to 60°C causes resistance to rise from 2.016 Ω to 2.338 Ω. Power losses increased from 45,360 Watts to 52,605 Watts, while daily energy losses increased from 1,088.64 kWh to 1,262.52 kWh. A temperature increase of 40°C resulted in an increase in energy losses of approximately 15.97%. The research results indicate that conductor temperature has a significant effect on the magnitude of energy loss in distribution lines. Therefore, loss calculations in distribution networks should consider actual operating temperatures to obtain more accurate and realistic estimates of energy loss

Abstract

This study develops a sustainable coastal resort design at Pantai Mangrove, Serdang Bedagai, as a response to the rapidly growing tourism pressure in an area lacking environmentally responsible facilities. A sustainable architectural approach grounded in biophilic design is applied to translate human–nature connectivity into spatial strategies and building performance. The design principles include the use of locally sourced, low-carbon materials; optimization of cross-ventilation and natural lighting; integration of vegetation for both aesthetic and ecological functions; efficient rainwater and wastewater management; and site planning that respects the sensitivity of coastal ecosystems. The design methodology encompasses site observations, space programming, and environmental standards review to ensure measurable performance outcomes. The resulting proposal features an organically inspired morphology derived from seashell and wave forms, reinforcing the identity of the coastal setting while enhancing visitor comfort, reducing operational energy loads, and supporting the local economy. This design has the potential to serve as a replicable model for sustainable coastal tourism development in North Sumatra.

Abstract

This study aims to analyze the effect of optimizing the Electricity Usage Control Program (Penertiban Pemakaian Tenaga Listrik – P2TL) on the reduction of non-technical losses at PT PLN (Persero) ULP Sukadana. Non-technical losses are generally caused by electricity theft, meter reading errors, and misuse of customer installations, which can lead to significant financial losses for the company. The research employed a quantitative approach, with data collected through documentation, field observations, and interviews with P2TL officers. Data analysis was conducted using linear regression to determine the relationship between the effectiveness of the P2TL program and the level of non-technical loss reduction. The results indicate that P2TL optimization has a positive and significant effect on reducing non-technical losses. Improvements in P2TL effectiveness, such as increased inspection intensity, the use of more accurate detection equipment, and stricter enforcement of sanctions for violations, were proven to reduce energy losses. These findings confirm that a well-managed P2TL program can serve as an effective strategy for PLN to enhance operational efficiency and minimize losses resulting from non-technical factors.
