Abstract

Accurate carbon market price prediction is one of the fundamentals in assessing the risks associated with carbon trading. Related studies on carbon price prediction were mainly focused on two major approaches: mathematical and/or machine learning models. Geometric Brownian Motion (GBM) is one of the mathematical models that can represent carbon price movements but requires modifying the sample size and the number of parameters for compiling the simulation numerically. Moreover, two critical parameters: (μ) mu and (σ) sigma need to be estimated to simulate the carbon price movements. In this study, the parameters μ and σ estimation are based on the average return value and standard deviation. However, if the carbon price movement is very volatile, we need to recognize its trend and characteristics by estimating the parameters precisely until there is no significant change (or stable) patterns. That is very expensive and may be intractable on high-dimensional data with less precise prediction. Therefore, we propose a hybrid model for carbon price prediction based on GBM with the parameter estimation using the Long Short-Term Memory (LSTM) model. The LSTM model was chosen because it has high accuracy in parameter estimation without losing the characteristics of the GBM stochastic model. Furthermore, Value at Risk (VaR) is utilized to measure the risk of carbon price volatility predictions. The simulation results showed the proposed model has higher prediction accuracy with a not-too-significant time difference, and the model is proven reliable in measuring future risks.

Abstract

Abstract Electricity sales represent a crucial aspect of the business operations of the Perusahaan Listrik Negara (PLN). PLN is required to continuously improve its electricity sales strategies and enhance its services to meet the growing demands of its customers. PLN’s Customer Service Unit (ULP) Belawan is located in the northern part of Medan City, North Sumatra Province. PLN ULP Belawan serves a total of 75,931 customers with a total installed capacity of 220.28 MVA. In 2023, electricity sales reached 484.86 GWh, which is 105.63% of the target. The sales target for 2024 has been set at 524.46 GWh. This thesis aims to present the results of customer zoning prioritization that can be used to improve service delivery more effectively within PLN ULP Belawan. Through the weighting process using Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP), as multi-criteria decision-making methods, were to optimize criteria and contribute to enhancing electricity sales performance. Each customer zone was evaluated based on several criteria, including system reliability, electricity usage regulation (P2TL), improvement of disturbance and complaint services, replacement of electricity meters, enforcement of the 720-hour usage regulation, connection criteria, cash-in performance, and accurate meter reading. The research successfully identified customer zones based on priority criteria. For the criterion of Electricity Usage Regulation (P2TL), the total energy recorded was 341,841 kWh across 173 kWh meters. Of this total, Zone 12 contributed the most with 277,019 kWh, followed by Zone 14 with 43,098 kWh, and Zone 6 with 20,914 kWh. In the Accurate Meter Reading criterion, the total energy achieved was 157,311 kWh from 815 kWh meters. Zone 14 contributed the highest amount at 67,564 kWh, followed by Zone 12 with 48,580 kWh, and Zone 6 with 41,167 kWh. Meanwhile, for the criterion of Electricity Meter Replacement, the total energy gained was 65,559 kWh from 505 kWh meters, with the largest contribution coming from Zone 6 (26,910 kWh), followed by Zone 12 (26,688 kWh), and Zone 14 (11,961 kWh).

Abstract

Reliable carbon price prediction can help to stabilize the carbon market, minimize financial risks for investors, and encourage innovation in green industries. The forecasts have a crucial role in reaching advanced goals for reducing emissions, aiding the shift toward an economy with reduced carbon emissions, and lessening the adverse effects of climate change overall. This paper proposes applications of LSTM with Temporal Pattern Attention (TPA-LSTM) to predict carbon price fluctuations. The prediction of carbon price fluctuations not only draws on its own historical information but also from its main predictors, including fossil fuel prices from 2018 to 2023. The TPA-LSTM method is a combined method that uses the LSTM layer as the initial input of the model. Furthermore, the output generated by the LSTM layer serves as the input to the TPA layer, which is then used to predict the carbon price for the following day. The model is tested by predicting the test data and calculating the evaluation results. The experimental results indicate that TPA-LSTM has surpassed other models in accuracy by showing better performance based on MSE, RMSE, MAE, and MAPE metrics.

Abstract

Distribution transformer maintenance plays a critical role in ensuring the continuity and reliability of PLN’s electricity supply. Currently, PLN employs a Condition-Based Maintenance (CBM) approach, relying on a Health Index (HI) derived from Tier 1 and Tier 2 inspection outcomes. However, in practice, determining maintenance priorities remains largely dependent on the intuition and technical experience of decision-makers, leading to potential inconsistencies in decision-making. Additionally, the absence of a structured weighting mechanism among HI parameters and unclear relevance of indicators used further hampers valid and reliable decision-making aligned with current operational conditions. This research aims to propose a structured and adaptive Health Index evaluation method through the integration of the Delphi and Analytical Hierarchy Process (AHP) methods. The Delphi method was employed to identify the most relevant parameters based on expert consensus, while the AHP method provided logical and consistent weighting among these parameters. Although AHP does not entirely eliminate subjectivity, as it still depends on expert judgments, it offers a systematic and transparent way to manage conflicting criteria effectively. The Delphi application yielded seven sub-criteria parameters grouped into three main criteria: oil leakage, transformer body temperature, load percentage, grounding value, physical condition, transformer age, and neutral current percentage. Based on AHP analysis, the oil leakage parameter was identified as having the highest weighting (0.23), indicating its significant impact on transformer performance. Applying this methodology to 253 distribution transformers resulted in prioritizing maintenance into three categories: Priority I (4 transformers), Priority II (54 transformers), and Priority III (195 transformers). The findings and validation from this study demonstrate that a structured, weighting-based approach significantly enhances the accuracy and transparency of decision-making processes in asset maintenance management.

Abstract

PLN (Persero) East Bali Customer Service Implementation Unit is responsible for supplying electricity in Gianyar, Klungkung, Bangli, and Karangasem regencies. The high number of feeder disturbances, especially those caused by animals, significantly impacts the reliability and continuity of electricity supply, accounting for 115 incidents (37.33%) out of a total of 308 trips in the first semester of 2023. This study aims to determine the priority program for reducing animal-related disturbances using the hybrid Analytical Hierarchy Process (AHP) - Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method and to monitor its implementation using The Four Disciplines of Execution (4DX). The Delphi method established four evaluation criteria: ease of implementation, material cost, effectiveness, and power outage (KWH lost). Four alternatives were evaluated: installing palm fiber barriers, animal shields, heat shrink tubes, and tree pruning. The results indicated that tree pruning was the priority program. Implementation was monitored during the first semester of 2024 using the 4DX method, which showed a significant reduction in animal-related disturbances, decreasing from 115 incidents in the first semester of 2023 to 55 incidents in the first semester of 2024, representing a 52.21% year-over-year reduction. The implications of this study demonstrate that the hybrid AHP-TOPSIS and 4DX approaches effectively determine priorities and monitor program execution, significantly improving electricity supply reliability.

Abstract

Monkeypox is a zoonotic disease that can be transmitted from animals to humans. The monkeypox virus is the cause of monkeypox disease, which belongs to the orthopoxvirus family. Although the mortality rate from monkeypox is not as high as COVID-19, this virus can be the cause of the next global pandemic if the epidemic worsens. Therefore, it is very important to carry out proper surveillance and prevention to prevent the spread of this disease. In this study, researchers developed another method to detect monkeypox disease based on its symptoms using the classification by association (CBA) method. CBA integrates the advantages of classification and association analysis, allowing the classification process and a deeper understanding of the strength of the relationship between features in the dataset through the analysis of metrics such as support and confidence. Based on the results of the experiments in this study, an accuracy of 68.64%, a precision of 92.21%, and a sensitivity of 71.09% were obtained. In this case, the accuracy obtained is still low, but the results of other metrics show that the CBA model performs fairly well in predicting the positive class with high precision.
