Abstract

The development of the number of customers in PT PLN (Persero) Rayon Kefamenanu increases every year. PT PLN (Persero) As a power supply company must be able to meet the electricity distribution to customers continuously. In preliminary observations of customers at PT PLN (Persero) Rayon Kefamenanu often experienced blackouts both in the number of outages and a long outage. This outage will result in losses for both the customer and PLN itself, so it is necessary to study the reliability of the distribution network system by calculating SAIFI and SAIDI.From the calculation of the SAIFI and SAIDI index values in 2017, 2018 and 2019, a comparison is made with the SPLN 68-2: 1986 standard values as follows: For the SAIFI reliability index values in 2017, 2018 and 2019 when compared to the SPLN 68-2: 1986 standards with the maximum value of the SAIFI standard of 3.2 times / customer / year is categorized as not reliable because the magnitude of the SAIFI count exceeds the SPLN 68-2: 1986 standard. For the SAIDI reliability index values in 2017, 2018 and 2019 when compared to the SPLN 68-2 standard : 1986 with a maximum value of SAIDI standard of 21.09 times / customer / year there is 2019 categorized reliable because the SAIDI calculation value is smaller than the SPLN standard value of 68-2: 198 and 2017 and 2018 are categorized as not reliable due to the magnitude of SAIDI calculated Exceeds SPLN 68-2: 1986 standards.While the large number of kwh losses that were not channeled due to disruptions that occurred in 2017, 2018 and 2019 at PT. PLN (Persero) Kefamenanu Rayon is: The value of ENS (Energy Not Served) in 2017 of 24,866.1 kwh or a cost loss of Rp 36,485,513,208. The value of ENS (Energy Not Served) in 2018 is 17,122.37 kwh or a loss in cost of Rp.25,123,311,0536. The value of ENS (Energy Not Served) in 2019 is 10,402.45 kwh or a loss in costs is Rp 15,263,306,836.

Abstract

Many sites in Indonesia contain of soft soils which mainly located in farming areas, slopes, alluvials, low level areas. The main problem of soft soils for performing construction work is big settlement which is caused due to low ultimate bearing capacity of soils.These low bearing capacities occurred because of consolidation process proceeded in long time and slowly. To solve this problem the geotechnicians has tried to modify some methods to increase the ultimate bearing capacity of soft soils. There are many methods have been introduced and widely used for increasing bearing capacity. This paper discuss about four methods such as Bamboo Piles Method, Pre Loading Method, Vertical Sand Drainage Method, Geotextile Method.Bamboo Piles Method use bamboo as reinforced soft soils. Pre Loading Method used Pre Loading as the beginning loading. This loading aimed to conduct process of settlement in shortier time. Vertikal Sand Drainage Method required installation of vertical Drainage to clear sands on the soils layer. After draining and pre loading consolidation process was expected would be proceeding in shorter time. Geotextile Method used material of geotextile as tension force to reinforce soft soils so that the ultimate bearing capacity increased. The maximum bearing capacity would be obtained if users installed it as well as soil's layer condition.

Abstract

The need for energy in the world continues to increase while the fossil energy source used continue to run out, so an alternative energy is needed to supply energy needs. Electrical energy is an indispensable energy. The sun (sunlight) is one of the renewable energy, it can be used to generate electrical energy. Indonesia is a tropical country, so sunlight is available quite a lot. To get efficient and safe (consistent) electrical energy, you can use solar energy that is backed up with PLN's electrical energy (hybrid system). The planned hybrid system uses 200 WP (11 units) Solar panels, 100 Ah 12 V batteries (1 unit), Hybrid controller system with 1000 watt inverter, 12 Volt 10 A Charger Control. In use, charging the battery current for 6 hours. The way this hybrid system works is that the voltage is read using the INA219 voltage sensor, which will be processed on the Arduino Nano, and forward it to the relay to regulate the power source used, and display how much voltage is on the LCD. When the battery voltage runs out, usually at night, or the weather is cloudy, measured at 11.2 volts or below, the relay will switch the source from the battery (inverter) to the PLN source, the relay takes 1 second. And when the weather is sunny or the solar panel is exposed to a source of sunlight, measured at 12.0 volts or above, the relay will replace the power source from PLN to the battery (inverter), and the relay takes 1 second.

Abstract

The use of electrical energy and water is very critical in the hotel industry because of almost all operational equipment support are uses electrical energy and most of the hotel operation using water. However the use of electrical energy and water should be used efficiently. According to Government Regulation No. 70 year 2009 Article 10 (1), that individuals, business entities and permanent establishments in energy supply activities are obliged to carry out energy conservation. This process includes an Energy Audit, which is a method to calculating energy use in a building where the results obtained to be compared with the existing standards so that it can be seen whether the energy use in the building is efficient or not. The standard used is the USAID-ASEAN Energy Consumption Intensity (IKE), which is 300 kWh/m2/year for the electricity standard and for the water standard is using USAID|Indonesia Water Consumption Intensity (IKA) which the standard for Bali area is 3.48 m3/room occupied/year. The Energy Audit at hotel Uma Ubud Bali is obtained an IKE of 207.78 kWh/m2/year and an IKA is 2.58 m3/room occupied/year so that it can be said that the use of electricity and water at hotel Uma Ubud Bali is likely to be inefficient, so an analysis of Energy Saving Opportunities (PHE) is needed. Energy Saving Opportunities at the hotel Uma Ubud Bali can be implemented in periodic AC maintenance, the use of motion sensors, replacing conventional water heaters with heat pumps, reducing the pool water pump operating hours, replacing inefficient light bulbs into LED light and maximizing of using grey water from waste water treatment plant to watering plantation and irrigating fishpond.

Abstract

This study evaluates the comparison between conventional methods and the firefly method in the protection coordination of power systems with the addition of Distributed Generators (DG). DG is a crucial component in modern systems that can influence the performance of protection and existing protection coordination. Conventional methods involve relay setting adjustments and fault current coordination, but the addition of DG can significantly alter system characteristics, affecting the performance of conventional methods. This study introduces the firefly method, which utilizes an optimization algorithm inspired by the light-emitting behavior of fireflies to dynamically adjust relay settings, considering system changes due to the addition of DG. The results indicate that the firefly method enhances protection coordination performance by being more adaptive to system changes. Compared to conventional methods, the firefly method provides better responsiveness to dynamic variations in power flow and fault currents. Thus, this study concludes that implementing the firefly method in power system protection coordination with DG integration can improve system reliability and the overall efficiency of DG utilization. This method offers a more adaptive and responsive solution to changes in modern power systems.

Abstract

Solar Power Plants (SPP) are one of the main solutions in the utilisation of renewable energy. However, their efficiency is often hampered by the variability of solar radiation and ambient temperature. To overcome this, Maximum Power Point Tracking (MPPT) technology is required so that solar panels always operate at the maximum power point (MPP). This study develops a Mamdani fuzzy logic-based MPPT system using MATLAB Simulink on a 10 WP PLTS prototype. The fuzzy algorithm is designed with two inputs, namely power and voltage, and one output in the form of a PWM signal to regulate energy conversion efficiency. Five test scenarios were conducted with different input combinations to compare the results of MATLAB simulations and manual calculations using the centroid weighted average method. The results show that the difference between simulation and manual calculations ranges from 1 to 11 PWM units (average <5%), with output classification remaining consistent in the Low, Medium, and High categories. This demonstrates that the Mamdani fuzzy manual method is valid and reliable as an adaptive control solution for PLTS systems. This implementation is expected to significantly improve energy conversion efficiency and support the achievement of national clean energy targets.

Abstract

Karimunjawa Island, as one of the very small islands in Indonesia, faces serious challenges in meeting raw water needs due to limited surface water resources and high evaporation rates. Evaluating water availability is essential to support the needs of the local population and the tourism sector. This study aims to compare two methods of estimating raw water availability, namely the NRECA and FJ Mock methods, using data on rainfall, climatology, hydrology, geography, topography, population, vegetation, evapotranspiration, and infiltration. The analysis results show that the NRECA method produces a maximum discharge of 0.726 m³/s in January and a minimum discharge of 0.000 m³/s in August. Meanwhile, the FJ Mock method yields a maximum discharge of 0.927 m³/s in December and a minimum discharge of 0.004 m³/s in August. In addition to the analysis results, this journal also presents sample calculations using both methods. Based on the findings, the NRECA method is considered more suitable for application in small island areas with limited data and complex hydrogeological conditions.

Abstract

Prof. Muhammad Yamin Street in Tegal Regency is a primary collector road with a two-lane, two-way undivided configuration, stretching for 2.2 kilometers. This road serves as a connector between sub-districts and is frequently used by the public, especially during school rush hours. The increase in traffic activity in this area creates potential conflicts between vehicles and pedestrians, particularly students. This study aims to identify the level of traffic accident risk along this road segment. The method used is HIRARC (Hazard Identification, Risk Assessment, and Risk Control), which allows for a systematic analysis of potential hazards, risk assessment, and control strategies. Survey results indicate that the condition of road markings and traffic signs falls into the moderate-risk category, while physical road damage such as ravelling, cracking, and potholes is classified as extreme risk. Several signs were also found to be covered by vegetation or vandalized. Recommended control measures include repainting road markings, maintaining traffic signs, and repairing pavement damage. These findings are expected to contribute to tangible improvements in road safety and serve as a consideration for policymakers in managing safer and more sustainable road infrastructure.

Abstract

The appreciation and speed of technological development and deployment in artificial intelligence (AI) bring enormous risks and opportunities to the developing world. Developing countries are likely to have less vested systems of regulation which risk ethical liability, legal liability, and social inclusion. This article presents an interdisciplinary legal framework for AI regulation for developing countries for the responsible deployment of AI vis-a-vis innovation relative to fundamental human rights and ethical safeguards. Using a huge trove of scholarly articles, policy documents, and case studies dating from 2017 to 2025 from journals such as Springer, IEEE Access, Wiley, MDPI, and ACM, this research synthesizes interdisciplinary lessons in computer science, law, ethics, and social sciences. The review of the troves of data highlighted important aspects of regulation, risk management, and governance principles towards AI regulations in emerging economies. The model proposed in this paper includes a mandatory assessment process for AI, deal with standards for algorithmic explain ability, autonomous regulatory agencies, sectoral risks, principle of inclusive design, public education in digital literacy, and strong protections for human rights. Developing countries require a rights-based, multi-stakeholder regulatory approach that addresses the technical, ethical, and legal complexities of AI. Implementing such a framework will promote equitable AI innovation while safeguarding human rights and fostering sustainable development.
