Analisa Tingkat Kepuasan Pelayanan pada Aplikasi PLN Mobile dengan Metode Service Quality

This study aims to analyze user satisfaction with the PLN Mobile application using the Service Quality (SERVQUAL) method. PLN Mobile is a digital innovation from PLN, offering services such as electricity payment, token purchase, and e-commerce for electrical equipment. The SERVQUAL method assesses the gap between customers' expectations and perceptions across five dimensions: tangibles, reliability, responsiveness, assurance, and empathy. Data collection involved questionnaires focusing on users' perceptions and expectations, complemented by direct observations of user interactions with the application. The findings reveal negative gaps across all Service Quality dimensions, indicating that customer perceptions fell short of their expectations. The largest gap was identified in the assurance dimension (-23.2), followed by responsiveness (-16.88). The tangibles dimension also showed significant shortcomings (-8.48), mainly concerning the application's interface and functionality. While the application performed relatively well in terms of reliability and responsiveness, substantial improvements are needed across all dimensions to enhance user satisfaction. These results offer strategic insights for improving PLN Mobile to become more responsive, reliable, and aligned with user needs in the future.

Toward sustainable environmental management: Insights from Chinese first-tier cities' consumers' response to green electricity payment policies

China's renewable energy industry is facing the challenge of overcapacity. The environmental management literature suggests that consumers' participation in the green electricity market holds immense potential in addressing renewable energy consumption concerns. However, the question of how payment policies influence China's consumers' willingness to pay for green electricity remains unresolved. Based on 2854 valid questionnaires from a survey conducted in China's four first-tier cities in 2023, our research findings reveal: (1) While 97.9% of consumers express a willingness to use green electricity, only 63.1% are willing to pay a higher cost, indicating the existence of a “value-action” gap between environmental awareness and actual willingness to pay. (2) China's consumers' willingness to pay for green electricity is approximately 38.4 RMB per month. This figure has decreased by 5.7 RMB compared to our survey in 2019. (3) Consumers' willingness to pay will be influenced by the attitudes of those around them. (4) The voluntary payment policy positively impacts consumers' willingness to pay for green electricity. (5) Male, younger, lower education level, higher income, and larger household size consumers exhibit a higher willingness to pay. (6) Electricity price sensitivity weakens the impact of payment policies on willingness to pay.

Integration of a Smart Power Meter for Monitoring Household Energy Consumption in Prepaid Electrical Systems

Indonesian households have widely embraced the prepaid electricity payment system. The system relies on electricity credits, with each electrical device consuming credits as a unit of measurement for energy usage. A common issue is the automatic cutoff of electricity supply when the credits are depleted. This research designed a smart power meter using Current Transformer and voltage sensors. The electrical token value is then stored in the Arduino's EEPROM before being transmitted to the NodeMCU. The NodeMCU transfers the data to Antares using the MQTT protocol to forward it to the subscriber, typically an Android device. The data sent to the Android application includes current, voltage, active power, frequency, cos φ, and electrical credits. The measurement of electricity consumption on a kWh meter involves subtracting the value of the input electricity token from the device-measured electricity usage. The device sends a WhatsApp message when the remaining credit exceeds 10 kWh. The prototype of the smart power meter demonstrates practical functionality, with the current sensor accuracy at 99.983% and the voltage sensor accuracy at 99.999%. The largest measurement difference of the electric credit balance between the PLN Meter and the prototype is 0.04 kWh over a test period of 72 hours.

RANCANG BANGUN WEB MONITORING SISTEM PADA MESIN KONVERSI LIMBAH ORGANIK MENJADI ENERGI LISTRIK

UD. Nadi Utama is one of the producers and distributors of traditional snacks. As a snack producer, UD Nadi Utama supplies 5 minimarkets every day. To support its business, UD Nadi Utama installs PLN electricity with an average electricity payment of IDR 750,000 per month which is considered to burden production costs. After conducting observations, the capstone project team found that UD, Nadi Utama produces 25 kg of coconut fiber and shell per day. From the problems and potential found at UD Nadi Utama, team capstone project provides a solution in the form of an incinerator. This incinerator has a converter device that can convert the heat generated from combustion into electrical energy. However, monitoring the data of voltage, current, temperature, and the power generated by this incinerator is quite difficult for ordinary users. Because the resulting data is stored in a data logger that can only be downloaded in the form of excel files and cannot be known directly (real-time). This makes it difficult to know when the temperature of the device has decreased, and the amount of power generated by the device. At UD Nadi Utama itself, its human resources have a good ability to use the web system on their mobile devices. From the problems with the conversion tool and the potential of human resources at UD Nadi Utama. A website-based monitoring system is created, which displays the data generated by the data logger in almost real time.

Promoting Cashless Economy: The Use of Online Electricity Payment Channels in the Ibadan Metropolis, Nigeria

The study was designed to investigate the level of usage of online electricity payment channels (OEPC), as well as the influential factors determining the use of the channels. The correlation type of survey research design was adopted. The population consisted of all electricity consumers in the Ibadan metropolis, Nigeria. Out of the 236 responses, about two-thirds (65.3%) were users of OEPC, while 34.7% were not. A significant relationship, strong and positive correlation was found between usefulness, ease of use, convenience ( r = 0.710, 0.704, 0.623, respectively) and use of OEPC. The relationship between security and computer self-efficacy and the use of OEPC is also positive and significant but the correlation coefficients are low ( r = 0.279, 0.252, respectively), indicating a weak relationship. All the variables jointly predicted the use of OEPC, while a 24.0% variation in use was influenced by the variables. The study concluded that the use of OEPC by consumers in the Ibadan metropolis was moderate and that the usefulness of OEPC, ease of use, convenience of using, security of the channels and the computer self-efficacy of the users influenced the use of the channels. The implication is that these factors could be leveraged to promote an increase in awareness, adoption and use of OEPC in Nigeria.

Adaptation and application of the Algorithm for Inventive Problem Solving in the design of the automatic control system for pumping water station

The growing demand of visitors to hotels oriented to the ecological and cultural tourism approach represents a challenge for the optimization of water resources, in contrast to traditional hotels, these depend exclusively on water wells. This type of commercial establishment is growing in Latin American countries such as Mexico, El Salvador, Ecuador, as well as in European countries such as Spain. The solution to this problem is of great importance for this type of tourist establishments. The environmental and economic spheres are the most affected due to this problem. This is due to the waste of water and excessive payment for electricity. There are many advantages related to the automation of the pumping system: the ability to save fuel resources, reduce machine wear for maintenance and repair time. This cost and time savings will increase the profits of the hotels, while the workload of the maintenance Department is reduced because the constant monitoring of the water level in the tanks would not be necessary. This article focuses on the specific case of a hotel in the province of La Libertad in El Salvador. The data is analyzed to determine the initial conditions of the technical problem. An algorithm for Inventive Problem Solving is applied in order to develop a system that performs the water supply automatically, receives signals by means of level sensors, starts or stops the pumps (if necessary), and detects water leaks with the use of pressure sensors, reducing the waste of water and electricity.

Biomethane: production, economy, and opportunities for connection to gas distribution networks of Ukraine

The purpose of the work is to study the peculiarities of starting the production (generation) of biomethane in Ukraine, as well as to substantiate the economical features and the possibility of connecting the biomethane generation center to gas distribution networks in the regions of Ukraine. The methods used to study the specified problem are analytical; comparative; theoretical; empirical; systemic; functional; economic and sociological possibilities of application. The production and practical use of biomethane in various production processes of farms, as well as for its consumption by the population for domestic purposes, will contribute to a significant reduction in energy costs. It will contribute to increasing the energy independence of biomethane consumers, as well as the formation and further development of new (regional) enterprises specializing in biomethane production. The results of the research consist of: a thorough study of the concept of biogas and biomethane, raw materials and production technology; technical and economic justification for the construction of a biomethane plant; comparison of the cost of production and sale of electricity and biomethane from biogas; the regulatory and legal aspect regulating the processes of registration, maintenance of the plant, as well as further trading of biomethane; ways and conditions for connecting biomethane producers to gas distribution networks in the regions of Ukraine. All the research results listed above will contribute to the start of biomethane production in the regions of Ukraine. Summarizing the outlined features of connecting biomethane producers to gas distribution networks, the following aspects are worth noting: 1. Operators of gas distribution networks will not buy biomethane directly from producers. After all, the biomethane producer must find a supplier in Ukraine or abroad, or the producer can sell biomethane directly to an industrial consumer. In this case, a supplier's license, or the producer's consumption of biomethane is required. 2. The high level of natural gas prices is increasingly forcing large consumers to look for alternatives to natural gas. Therefore, for agricultural producers, this production cycle is closed. The high level of natural gas prices allows biomethane projects to have a high level of profitability. The process of decarbonization requires abandoning fossil fuels and replacing them with clean, new types of energy, including biomethane. 3. Biomethane compared to electricity. Today, the level of payment for electricity from the state under the "green" tariff is 30-40% of the total level of payment. The state limits payments and reduces opportunities to receive a "green" tariff, valid until 2029, and every year the rates are lower for new facilities.

New conditions for applying surcharges (discounts) to electricity payments for generation and consumption of harmonic component currents

Technical means of suppression of harmonic component currents installed in the consumer's electric network are able to reduce the level of harmonic component currents and reduce the harmful effects of their flow. The consumer's interest in installing such means is significantly increased when discounts (surcharges) are applied to the payment for electricity consumed for generation and consumption of harmonic currents. However, the attempt to apply allowances (discounts) has failed in the past. The article proposes to review and discuss new conditions for the application of surcharges (discounts) to the payment for electricity for generation and consumption of harmonic currents, taking into account the unsuccessful experience of use in the past. The article proposes a methodology for calculating and using surcharges (discounts) to the payment for electricity consumption for generation and consumption of harmonic component currents to manage the power quality in the power supply systems of consumers of a grid organization with nonlinear loads.

This article solves the problem of forecasting a time series which describesing electricity payments of individualfor electricity by physical customers of a power supplyn energy marketing company. The complex and non-stationary nature of the time series, along with it is complex and non-stationary, seasonality and trend are expressed in it, which limits indicates that it is impossible to choose using simpler forecasting methods, such as extrapolation or naive forecasting method. Therefore in this regard, various machine learning methods and neural networks were chosen to solve the problem, various machine learning methods and neural networks were chosen which can find complex dependencies in data and learn to predict them. To solve the problem, several regression models of machine learning were chosen, often used in solving time-series forecasting problems, for example, XGBoost, SVM, LSSVM, LGBM, and Gradient Boosting, as well as neural networks, such as LSTM, RNN, and CNN. The best result was obtained using a regression support vector regression machine (SVR) machine. This implementation of this model has been integrated into a web application for time-series forecasting. The article also discusses an algorithm for determining the stationarity of a series using the Dickey–Fuller test and bringing a time series to a stationary series one by differentiating the former one a time series. In addition, the article addresses discusses the problem of forecasting emissions (peaks). Most forecasting methods do not solve the problem of predicting peaks because they consider them statistical outliers. In the article, this problem is solved by separating the peaks into a separate time series and predicting them separately from the main series with further connection of the two forecasts.

Residential power scheduling based on cost-coupling constraint with distributed generation

Power scheduling is a major task for demand response (DR) to cope with the electricity consumption during the peak period in smart grid. In the residential sector, consumers trend to trigger their electrical appliances when the electric price is low. However, power scheduling including load curtailment, time delay and equipment power adjustment will change consumer’s comfort level to produce discomfort cost. Thus, electricity payment and discomfort cost are coupled to constraint the DR. In this paper, we focus on renewable energy use by smart homes and consider cost-coupling constraints, taking an approach whereby we decouple the primary problem into several independent subproblems. A novel DR algorithm based on cost-coupling constraint with distributed generation is developed to reduce consumers’ expenditure while improving their comfort. To that end, a day-ahead bidding price mechanism including real-time charging management is introduced, and a cost efficiency algorithm is designed based on electricity payments, discomfort and distributed generation. Simulation results demonstrate that the proposed method is effective and feasible when tested in real application scenarios.

ГІБРИДНА ФОТОЕЛЕКТРИЧНА СИСТЕМА З АКУМУЛЯТОРНОЮ БАТАРЕЮ ДЛЯ ЛОКАЛЬНОГО ОБ’ЄКТУ З ЗАВДАННЯМ ПОТУЖНОСТІ, ЩО СПОЖИВАЄТЬСЯ З МЕРЕЖІ

The issues of increasing the efficiency of a hybrid photovoltaic system with a storage battery used to meet the own needs of a local object are considered. This is achieved in the case of a setting according to the forecast of power consumption from the grid, which ensures the formation of the necessary graph of the degree of charge of the battery. A technique for determining the parameters is substantiated when achieving the maximum reduction in the cost of electricity consumed from the grid for the accepted load schedule for the average monthly generation of a photovoltaic battery in summer. Implementation scenarios are proposed in accordance with the accepted billing of payment for electricity. The possibility of leveling the graph of power consumed from the network and reducing consumption during peak hours is shown. The invariance of control is confirmed under the conditions of load changes over time within a certain energy value at intervals in the daytime and in the evening. The possibilities of implementing the proposed control scenarios are confirmed by modeling energy processes in the daily cycle. At the same time, archival data on the generation of a photovoltaic battery from open web resources were used. The solutions obtained are the basis for the design of software control complexes for photovoltaic systems with batteries with improved energy efficiency.

LOSISH—LOad Scheduling In Smart Homes based on demand response: Application to smart grids

The evolution towards Smart Grids (SGs) represents an important opportunity for modernization of the energy industry. It is characterized by a bidirectional flow of information and energy between consumers and suppliers. However, the rapid increase of energy demands in residential areas is becoming a challenging problem. In order to address this issue, Demand-Side Management (DSM) has proven to be an effective solution. In this paper, we propose LOSISH, a price-based Demand Response (DR) system for load scheduling in residential Smart Homes (SHs) that achieves a trade-off between electricity payments and consumer’s discomfort. Our proposed system considers Renewable Energy Sources (RESs), Battery Energy Storage System (BESS) and Plug-in Electric Vehicle (PEV). We formulate our scheduling as a constrained optimization problem and we propose a new hybrid algorithm to solve it. The latter combines two well known heuristic algorithms: Particle Swarm Optimization (PSO) and Binary Particle Swarm Optimization (BPSO). Moreover, we propose a new clustering algorithm based on Machine Learning (ML) to extract consumer’s preferences from a real dataset that contains the historical consumption patterns of his smart appliances. We test our approach on real data traces obtained from a SH and we set up an experiment to evaluate our algorithm on a Raspberry Pi and measure its energy consumption. To prove the effectiveness of our approach, we compare our results with another approach from the literature in terms of electricity bill, Peak-to-Average Ratio (PAR), energy consumption, and execution time. Numerical results show that LOSISH outperforms the other approach in terms of electricity bill (up to 52.92% cheaper), PAR (up to 44% decrease in peak demands), energy consumption (up to 69.44% less consumption), and execution time (up to 63.15% faster).

Penerapan Data Mining Pada Penjualan Produk Digital Konter Leppangeng Cell Menggunakan Metode K-Means Clustering

The Leppangeng Cell counter is a counter that sells digital products in the form of Credit, Data Packages, PLN Electricity Tokens, Electricity Payments, BPJS Payments, PDAM Payments. Spidy or Indihome Payments, Home Phone Payments, Postpaid Payments, Game Voucher Sales, Cable TV Payments, Credit Installment Payments, Train Ticket Payments, PGN/Gas Payments, Shope Payments and Cash Transfer Services and Top Up. However, from the counter sales, of course, not all of them sell well, there are also products that don't sell. Sales data, purchases and unexpected expenses at the Leppangeng Cell Counter are not well structured, so the data only serves as a store archive and cannot be used to develop marketing strategies. Therefore, it is necessary to apply data mining using K-Means at the Leppangeng Cell Counter. The K-Means method can be applied to the Leppangeng Cell Counter to determine sales of digital products that are selling well and not selling well. The application of the K-Means method at the Leppangeng Cell Counter is by grouping digital product stock data. Then select 3 random grub as initial centroid. After the data for each group does not change, the results of data processing are obtained in the form of 114 products that sell, 5 underperforming, and 14 not sold. Then, the application of the K-Means method to Rapidminer is carried out by entering the initial product stock, the sold stock and the final stock to be changed and form K-Means. After that, Rapidminer will produce which products have high and low demand
