The Impact of Reduced Non-technical Distribution Losses on GHG Emissions by Implementing Advanced Metering Infrastructure
Authors: PRILIANI MEILY , I NYOMAN JENRA
Published: January 2024

The distribution losses in the electrical system demonstrate the reliability and efficacy of the network in providing electricity to the customers. The PLN Statistical Report 2022 stated that 20,236 GWh of electricity became losses at PLN’s distribution network across Indonesia. Not only causing the financial disadvantage, but these losses are also believed to have an adverse effect on the environment since they raise the amount of greenhouse gas (GHG) emissions because energy losses need to be compensated. Thus, various initiatives are conducted to improve the performance of distribution network system, including in Bali. In attempt to minimize losses, PLN Bali Distribution Unit has gradually implemented Advanced Metering Infrastructure (AMI) technology throughout 2023. This research is supposed to examine the impact of the AMI installation on the value of losses and GHG emissions. Our findings suggest that AMI technology has a positive impact on non-technical losses but an insignificant impact on total losses, defying the widely held belief that it can notably reduce losses. The environmental impact then can be quantified by converting the losses value to GHG emissions.

Published: January 2024

Water wheels are one of the examples of renewable energy generators that have been used for a long time. However, the improvement of the performance of simple water wheels still needs further investigation, especially regarding the influence of materials, as there has been limited research on this aspect. This study aims to conduct a comparative study of materials that can enhance the performance of a simple water wheel in harnessing hydro energy. In this research, the performance of water wheels made of wood, aluminum, and plastic was examined. Testing was carried out by measuring the voltage and electric current generated by the water wheels using a multimeter. The water wheels made of wood, aluminum, and plastic produced voltage and electric current values of 2.80 V and 6.90 mA, 2.88 V and 7.82 mA, and 2.93 V and 9.64 mA, respectively. The results of the study indicate that plastic exhibits better performance, as it generates higher voltage and electric current compared to wood and aluminum. The larger the values of voltage and electric current produced by the water wheel, the better its performance. Hence, the materials used in constructing a simple water wheel have an impact on its performance

As a peaking power plant, Semarang PGU runs a 1.4 GW combined cycle gas turbine (CCGT). Our power plants must start and stop on a regular basis, as well as respond to sudden spikes and drops in load caused by the peaking function. Operating this 30-year-old power plant is likewise getting tougher; the chief factors are component obsolescence and asset age. Tambak Lorok CCGT, on the other hand, was able to achieve less than 0.51% EFOR (Equivalent Forced Outage Rates) in 2022, which was a notable success given the power plant's age in terms of its ability to sustain dependability. Our company created a "end-to-end asset healthiness monitoring dashboard" that reduced the WMATL WO backlog by 14.65%. Semarang PGU completed maintenance efficiently in order to sustain the firm by increasing efficiency and minimizing OPEX. Our principal means of attaining this goal are to improve reliability management, develop a quality-based maintenance approach, and ensure shorter and safer outages. This strategy resulted in an Inventory Turn Over of 6.36 and a profit of IDR 722,695,530,067 for the firm. Our company also combines risk management into outage operations and innovates in asset management pillars integration, which uses real-time monitoring for an asset's life cycle.

Pengaruh Pembebanan Terhadap Efisiensi Transformator Distribusi Di PT. PLN (Persero) UP3 Garut
Authors: Hidayat M. Reza , Fadilah Iqbal
Published: January 2024

Transformer efficiency is defined as the ratio of the incoming power to the outgoing electric power. Even so the ideal transformer has 100% efficiency, this ideal transformer does not exist, because the energy that goes out is always less than the energy that goes in, meaning that there is energy loss. Load imbalance in an electric power distribution system always occurs and the imbalance is in single-phase loads in low-voltage network subscribers. Due to the load imbalance, a current appears in the neutral of the transformer. Perform analysis and compare efficiency. Analysis of used load capacity is not efficient. Analysis of the results of current and voltage measurements at the substation to obtain efficiency, and transformer losses in day and night conditions using LWBP and WBP methods. In this study, observations were made regarding the transformer efficiency analysis using the Outside Peak Load Time (LWBP) and Peak Load Time (WBP) methods. The LWBP method is carried out during the day for 20 hours, while the WBP method is carried out at night for 4 hours, from 18.00 to 22.00. Then measurements were made at PT. PLN (Persero) UP3 Garut. For the highest percentage of loading which is close to the standard of 80%, namely the afternoon loading at the PDDK substation, which is 50.93%, the load used is 50.93 kVA. The night load at the CITL substation is 77.49%, the load used is 77.49 kVA. For the lowest percentage of loading that deviates from the standard 80%, namely the daytime loading at the SJRK substation, which is 16.32%, the load used is 16.32 kVA. The night load at the SJRK substation is 21.52%, the load used is 21.52 kVA. Based on observations, it is not efficient because the unused load is very large, it is recommended to use a smaller transformer capacity. The highest efficiency in the LWBP method is at the CITK substation 97.87%, the lowest at the PDDK substation 94.55%. The highest efficiency in the WBP method is at SJRK substations 95.5%, the lowest at PDDK substations is 92.1%.

Published: January 2024

El artículo científico analiza la parasitosis intestinal y sus complicaciones en menores de 5 años en países subdesarrollados, donde la presencia de parásitos intestinales se asocia con malas condiciones higiénicas, socioeconómicas, geográficas y ecológicas. Los niños son especialmente vulnerables debido a la inmadurez de su sistema inmunológico y la falta de prácticas sanitarias adecuadas. Las infecciones pueden causar problemas digestivos, malnutrición y afectar el crecimiento y las capacidades cognitivas de los niños. La principal vía de transmisión es oral, a través del contacto con agua, alimentos o superficies contaminadas. La metodología empleada en el estudio es descriptiva y se basa en una revisión documental de artículos científicos. Se realizaron búsquedas en diversas bases de datos, utilizando descriptores y palabras clave relacionadas con el tema. Tras aplicar criterios de inclusión, se seleccionaron 32 documentos para su análisis. Los resultados muestran una alta prevalencia de parasitosis intestinales en regiones tropicales y subtropicales, con variaciones en la distribución de agentes infecciosos como protozoos y helmintos. Los protozoos, seres vivos unicelulares y altamente contagiosos, se transmiten principalmente por la vía fecal-oral. Los nematodos, también conocidos como gusanos cilíndricos, experimentan fases larvarias y presentan dimorfismo sexual. Ambos tipos de parásitos pueden causar enfermedades en los niños, siendo un problema importante de salud pública en países como Perú. La investigación destaca la necesidad de mejorar las condiciones sanitarias y educativas para prevenir y tratar las parasitosis intestinales en menores de 5 años.

The Effects of Uncertainty Disclosures on REIT Returns
Authors: Sahin Olgun Fuat , Koch Ethan
Published: January 2024

We examine the relationship between uncertainty-related disclosures in annual filings and market returns of REITs. We search annual filings (10-K) of Real Estate Investment Trusts (REITs) with the Securities and Exchange Commission (SEC) for uncertainty words. We then form rolling portfolios of REITs based on occurrences of uncertainty words in annual filing and track the returns. Our main finding is that there are no statically significant abnormal returns to these REIT portfolios. This supports the notion that the stock market is efficient in quickly incorporating any new information revealed in annual reports when the information becomes available.

This text outlines the executive decisions of “El Libertador” Simón Bolívar, based on accounting as he managed the redirection of the Republican Treasury, seeking a point of equilibrium between costs and income that would allow delaying the imminent transfer of financial control of Gran Colombia to the hands of international creditors. This a theoretical reflection on an ignored side of “El Libertador” as an accountant, scheduler, and manager of public finances, these emerged booths among the products of historical-educational research on the accounting system adopted by the authorities in charge of the republican destinies of Gran Colombia. The points of attention, on which Bolivar’s accounting actions are revealed, are condensed in the inability of the republican project to develop an accounting policy that envisioned the way to meet the needs of information and control required by the treasury and, in the ideological polarization between the departments of New Granada, Venezuela and Ecuador that prevented the implementation of any feasibility plan to avoid the trauma of the dissolution of the republic.

Ready for Robot Assistance? Exploring Gender Influences on Service Robot Adoption in Luxury vs. Economy Hotels
Authors: Lee HyeRyeon , Ma Han , Xiao Ge
Published: January 2024

The hospitality and service industries have rapidly integrated advanced robotics and artificial intelligence (AI) to elevate guest service, assist human staff, and provide unique experiences. During the COVID-19 pandemic, this trend accelerated as hotels particularly adopted technology-oriented services to meet stringent health and safety standards. Despite the evolution of consumption behaviors and preferences, a gap remains in understanding guests’ service preferences, specifically concerning the acceptance of service robots in the post pandemic hotel sector. In response, this study examines the role of gender in adopting service robots following the COVID-19 pandemic. The findings indicate that different hotel segments influence guests’ attitudes toward service robot adoption. Furthermore, the pandemic has shifted the perceptions of female hotel guests regarding service robots, making them more receptive to such services in luxury hotels, particularly when there are pronounced health and safety concerns.
Advertising and the Republic of Letters
Authors: Lopera Chaves María Teresa
Published: January 2024

Towards the end of the 19th century, in Colombia, men of letters dominated the cultural and political world, so it can be said that this country was the Republic of Letters. However, the economic and social changes that occurred with the turn of the centur y allowed new groups, such as entrepreneurs, to begin disputing political power, and for this, the use of images rather than words was decisive.

This article analyzes what happened to letters and images when they functioned simultaneously in the 1920s, taking the Antioquia case as a reference. There, Humberto Chaves, a master painter who also worked as a graphic designer and advertiser, was respons ible for creating images of the modern, which the entrepreneurs sought to use to dominate both the market and the national political sphere.
Legal Forms for Social Entrepreneurship in the Republic of Kazakhstan
Authors: Karagussov Farkhad
Published: January 2024

This article analyzes the first steps taken in Kazakhstan to create a legal and organizational framework for social entrepreneurship. The expediency to distinguish a specific type of legal entities (along with commercial and non-commercial legal entities) in the Civil Code of the Republic of Kazakhstan and to regulate special organizational and legal forms for conducting social entrepreneurship, is substantiated. The absence (at least in most cases) of traditionally understood financial investment relations in the establishment and financing of the activities of social entrepreneurship entities is stressed out. The need for the State to declare (as its political task) its focus on formation of a social and solidarity economy in Kazakhstan as a special sector of the national economy, together with the obligatory development of constitutional foundations to ensure the common good, recognition and observance of public interest, is emphasized. The objective needs to create an effective system of social finance to support and develop social economy in Kazakhstan is emphasized.
The Negative Effect and Consequences of Employee Turnover on the Saudi Oil and Gas Companies
Authors: Alamaj Waleed
Published: January 2024

The oil and gas sector in Middle East is facing many challenges regarding employee turnover especially in (DLPS) company. Employee turnover leads to reduce the employee's performance and productivity. Moreover, employee turnover also affects the organizational performance in general. High rates of employees' turnover cause many challenges to the organizations. Employee turnover has escalated to 14.2% in 2018 (DPLS, 2018). Likewise, many companies keep long service and loyal) employees intact while there are also other types of employees who leave their organization. The main idea behind choosing this topic is to address the reasons that cause the high rate of employees’ turnover and how to solve the issue. Moreover, the researcher aimed to investigate in depth the concept of how reward system and training could improve employee retention. To make this action researcher done, the researcher gathered data in questionnaire form (30 questionnaires) from previous and existed employees at DLPS Company and made five (5) interviews with departments managers to get valid data to build the study on. The results showed that, most of the targeted sample were not satisfied about their wages and the working time. In addition, due to the analysis of the quantitative and qualitative data, there is positive relationship between the hypotheses and the high rate of employees’ turnover.
False Face Must Hide What the False Heart Doth Know: Review and Model of Workplace Microaggression
Authors: Lee Raymond T. , O’Farrell Grace
Published: January 2024

Microaggression contains elements of workplace aggression, bullying, incivility, stigmatization, and ostracism. We argue that studies of the phenomenon should be broadened to cover all workplace members. Anyone with distinctly different ascribed status, physical and/or psychological characteristics from the mainstream may be subjected to negative micro-acts. We address two questions of concern: Why microaggression has not been recognized to be as problematic in “normalized” work settings as with bullying and harassment, and how workers exposed to such micro-aggressive acts might respond. Theories of signal detection and coordinated management of meaning are used to explain how targets attribute the reasons for these negative acts, and manage to either mitigate or prevent them. We suggest ways of reducing the prevalence of microaggression by coordinating the management of meaning between the perceiver-as-target and the perpetrator. This leads to adaptive coping (Marrs, 2012) and fosters supportive workplace climates (Kim et al., 2018). Implications for workplace practices and policies are provided.
Is Trusting Your Gut a Good Idea? Implications from The Emotional Mind
Authors: Whiting Elizabeth
Published: January 2024

What exactly does it mean to “trust your gut”? What use are gut-level insights when a person is attempting to consciously and deliberately navigate life altering decisions, such as those surrounding marriage, divorce, job changes, home buying, etc.? This essay provides a partial answer to those questions by leveraging the account of “emotional bodily feelings” offered in Tom Cochrane’s The Emotional Mind: A Control Theory of Affective States. This essay shows why “trusting your gut” is a reasonably good path to emotional self-awareness in decision-making. The first half of the essay offers an analysis of what many people mean by the colloquial advice to “trust your gut,” at least when they deploy that advice in context of an ongoing dialogue about a friend or family member’s major life-decision.
