Keandalan Jaringan Distribusi Di Pulau Panjang Dengan Pembangkit Listrik Tenaga Diesel
Authors: Samsurizal Samsurizal , Putra Arova
Published: January 2024

By examining the issue of the electrical power distribution system's dependability, particularly on the outer islands, in this case Pulau Panjang, it can be seen that the usage of electrical energy in Indonesia is still predominantly controlled by steam power plants. It is discovered that the Diesel Power Plant is this location's primary source of electrical energy. Since 2019, the use of PLTD has been running continuously here, with four primary engines operating efficiently. However, each day, only two machines run alternately for 12 hours, raising a reliability concern that has to be looked into. The SAIDI and SAIFI values obtained using these approaches are extremely high (403,645 for SAIDI and 16 for SAIFI), Then, it was claimed that an index comparison based on SPLN 68-2: 1986, IEEE, and WCS as of January 2022 to June 2022 was erroneous. Thus, the installation of PLTS in the Long Island region is required as a substitute for electrical energy. In order to achieve optimal performance, the diesel working time limit is decreased using the PLTS technology

Published: January 2024

Penelitian ini bertujuan untuk menganalisa dan melihat sejauh mana pengaruh regulasi terhadap percepatan perkembangan Energi Baru terbarukan di Indonesian khususnya Wilayah Sulawesi Utara, Sulawesi Tengah, dan Gorontalo, sesuai dengan Peraturan Pemerintah No. 79/2014 tentang Kebijakan Energi Nasional (KEN) serta Peraturan Presiden No. 22/2017 tentang Rencana Umum Energi Nasional (RUEN) mencanangkan target bauran energi baru terbarukan sebesar 23% pada tahun 2025. Target ini setara dengan kapasitas pembangkit listrik energi baru baru terbarukan (EBT) sebesar 45 GW. Kebijakan energi nasional merupakan kebijakan Pengelolaan Energi yang berdasarkan prinsip berkeadilan, berkelanjutan, dan berwawasan lingkungan guna terciptanya Kemandirian Energi dan Ketahanan Energi nasional. Dalam Penelitian ini menggunakan metode perhitungan BPP per Regional untuk menganalisa perbandingan antara BPP dengan harga jual tenaga listrik yang ada pada Peraturan Presiden no 112 Tahun 2022 tentang Percepatan Pengembangan Energi Baru Terbarukan. Tantangan yang dihadapi terkait pencapaian target diatas tidaklah ringan dan perlu upaya yang besar untuk mengejar pencapaiannya. Hal ini dikarenakan sebagian besar pembangkit berbasis energi baru terbarukan mempunyai biaya pembangkitan yang lebih tinggi dibandingkan dengan pembangkit fosil. Pemerintah terus berupaya untuk meningkatkan pemanfaatan EBT, khususnya untuk pembangkit listrik. Upaya tersebut tertuang dalam Peraturan Presiden (PERPRES) no. 112/2022 tentang Percepatan Pengembangan Energi Terbarukan untuk Penyediaan Tenaga Listrik setelah sebelumnya diterbitkan Peraturan Menteri ESDM No. 50/2017 tentang pemanfaatan energi terbarukan untuk pembangkit listrik. Pada Perpres No 112 /2022 diatur terkait harga pembelian tenaga listrik dengan pemberlakuan Harga Patokan Tertinggi dan Harga Kesepakatan. Wilayah Sulawesi Utara, Sulawesi Tengah dan Gorontalo (Suluttenggo) khususya untuk Palu dan Poso Grid sudah mempunyai jaringan interkoneksi, hanya PLTA skala besar yang layak untuk dikembangkan. Sementara beberapa wilayah Suluttenggo lainnya yang terpencil masih memungkinkan untuk pengembangan pembangkit energi terbarukan, terutama di wilayah yang masih menggunakan PLTD namun demikian dengan lokasi Potensi Sumberdaya Air yang berada jauh dari pusat beban mengharuskan Pengoperasian PLTD tetap harus beroperasi sebagai pengangkat tegangan agar dapat mempertahankan kualitas pelayanan kepada pelanggan. Hasil Analisa yang dilakukan menunjukan bahwa BPP sistem kelistrikan yang terhubung dengan grid mendekati harga jual berdasarkan perpres no 112 tahun 2022 untuk Sulawesi tengah (Palu- Poso grid) sebesar 7.48 cent USD sedangkan BPP setempat suntuk Pembangkit < 50 MW LCOE nya masih >7.41 cent USD.

Published: January 2024

ABSTRACT

Air balloon is a type of airplane that is used as a recreational vehicle. Apart from being a vehicle, air balloons are also used for other needs such as watering agricultural land. The development of this watering tool still needs further research. So that a air balloon can fly and move up and down is greatly influenced by the size and size of the burning flame. The size of the combustion flame is determined by the opening of the tap on the gas cylinder. Therefore, the tap opening on the gas cylinder must be controlled remotely so that the movement of the air balloon can be controlled. The aim of this research is to create a combustion flame control for a hot balloon using a PS2 stick. The method used is that controlling the opening of the gas tap must be done remotely, so it requires radio frequency communication to give commands. From the results of the PS2 stick communication test and the connection was lost at a distance of 34 m. Trials were carried out by varying the sizes of 2 m, 4 m and 7 m balloons. Based on the tests that have been carried out, the balloon can be lifted well, but it cannot lift the load it is carrying.

ABSTRAK

Balon udara merupakan jenis dari pesawat terbang yang digunakan sebagai wahana rekreasi. Selain sebagai wahana, balon udara juga untuk kebutuhan lain seperti penyiraman pada lahan pertanian. Pengembangan alat penyiraman tersebut masih perlu penelitian lebih lanjut. Agar balon udara dapat terbang dan bergerak naik turun sangat dipengaruhi oleh besar dan kecil api pembakaran. Besar dan kecil api pembakaran ditentukan oleh bukaan keran pada tabung gas. Oleh karena itu, bukaan keran pada tabung gas harus bisa dikontrol secara jarak jauh agar gerak balon udara dapat dikendalikan. Tujuan dari penelian ini adalah membuat kontrol api pembakaran untuk balon udara menggunakan stick PS2. Metode yang digunakan yaitu kontrol bukaan keran gas harus dilakukan secara jarak jauh, sehingga memerlukan komunikasi radio frekuensi untuk memeberikan perintah. Dari hasil pengujian komunikasi stick ps2 dan kontroler koneksi terputus pada jarak 34 m. Ujicoba dilakukan dengan memvariasikan balon dengan ukuran 2 m, 4 m, dan 7 m. berdasarkan pengujian yang telah dilakukan, balon dapat terangkat dengan baik, namun tidak berhasil mengangkat beban yang dibawa.

Penelitian ini berfokus pada pengaturan frekuensi kritis dalam sistem jaringan listrik di wilayah Jawa Bali, khususnya melalui penerapan Automatic Generation Control (AGC) dan Free Governor (FG) di PLTU Cilacap unit 3. Studi ini penting karena kapasitas pembangkit di wilayah ini mencapai 41.800,90 MW pada tahun 2022. Dengan metode pengumpulan data dari PLN Dispatch Center dan Load Rejection Test (LRT) dari PLTGU Tambaklorok Blok 3, studi ini mengamati respons frekuensi jaringan terhadap berbagai beban operasional dan kondisi AGC serta FG. Hasilnya mencakup pengamatan respon unit pembangkit terhadap fluktuasi frekuensi, di mana AGC dan FG berperan penting dalam pemulihan dan normalisasi frekuensi. Misalnya, pada beban 350 MW, respons terhadap frekuensi 50,09 Hz hingga 50,18 Hz menunjukkan penurunan beban 1-3 MW di bawah setting LOL. Pada beban 575 MW, fluktuasi frekuensi dari 49,89 Hz hingga 50,00 Hz mengindikasikan stabilitas frekuensi yang konsisten dengan AGC dan FG. Selama LRT dengan beban 746 MW, frekuensi berfluktuasi dari 50,09 Hz ke 49,86 Hz, dengan Pact berkisar antara 432 MW hingga 459 MW, menunjukkan respon yang cepat dan efisien dalam menstabilkan frekuensi jaringan. Penelitian ini memberikan wawasan berharga untuk pengembangan dan optimisasi sistem regulasi frekuensi di jaringan listrik skala besar.
From the Absorptive Capacity of Middle Managers and Their Employees to the Commitment in the Implementation of New Work Routines
Authors: Chevrette Nancie , Jean Eric
Published: January 2024

The objective of this proposal is to present a theoretical reflection on the concept of projects absorptive (absorption) capacity and the role of managers’ and employees’ commitment in the implementation of work routines. The general problem lies in a context of simultaneous project implementation, which can create additional pressure on employees with regard to available resources. The development of a theoretical framework, highlighting project implementation demands, absorptive capacity, routines and commitment, thus leads to the proposal of a three stage conceptual framework. The first moment represents the project during its implementation. The second moment specifically concerns absorptive capacity as a resource and the final moment highlights the relationship between absorptive capacity and commitment. Ultimately, this theoretical approach attempts to demonstrate that examining the project’s absorptive capacity reveals a significant theoretical originality, and that digging deeper into the concepts of commitment and work routines pushes the limits of project management research.

Published: January 2024

A comprehensive store-level data set of 9 dairy product categories across 149 stores of a supermarket retailer chain over 32 weeks in 2021 was used to examine the impact of store brands on overall category performance as measured by net margin dollars. The study examines results on both the overall dairy department and category specific performance. The results for the overall dairy department indicate there is not a significant positive relationship between a change in overall store brand sales penetration and profitability. There is, however, a significant positive relationship between overall store brand net margin dollar penetration and category profitability.
Integrating ESG in a Managerial Accounting Class
Authors: Diala Lucy U.
Published: January 2024

Among organizations and businesses, there has been a growing global attention on companies’ approach to climate change and sustainable development. Concurrently, the United States, Securities and Exchange Commission (SEC) has announced the intent to require publicly traded companies to disclose information on climate-related risks (SEC, 2022), signaling a need for carbon emission reporting integrated with financial statements. Accounting practitioners and educators are thus concerned with accounting students’ preparedness in developing skillsets that will meet the current demands for integrated reporting of climate-related and other sustainability or ESG mitigation measures (AAA, 2023). Despite this growing concern, few accounting cases address sustainability/ESG management. This case requires students to use data analysis to estimate the cost-benefit analysis across three variable costing budgets in a production cycle of a manufacturing plant while integrating the estimation of carbon emissions attributed to a number of products produced and sold. Students could synthesize relevant information on ESG issues related to production and make decisions on sustainable approaches to inventory production.
Panel Granger Causality Between Financial Development and Economic Growth
Authors: Ferreira Cândida
Published: January 2024

This paper uses panel Granger causality estimations with the approaches developed by Nair-Reichert and Weinhold (2001), and Bangake and Eggoh (2011) to analyse the causality relations between all the nine IMF financial development indices, and the real GDP growth considering a sample of 46 countries spread by all continents over the interval 1990-2017. The results revealed the dynamic character of these causality relations. Overall, no significant differences were found when comparing the results obtained for the financial institutions indices with those regarding the financial markets indices. The results confirm the existence of bidirectional causality, although not with the same statistical robustness for all the IMF indices addressing relevant aspects of financial development: access, depth, and efficiency of the financial institutions and markets.
An Appreciative Journey to the Formulation of a Business School Credo
Authors: Wallis Joseph
Published: January 2024

This paper narrates how a community outreach initiative to interview local leaders on organizational adaptation to COVID morphed into a systematic reflection on Emirati-expatriate leadership relations in the UAE with an eclectic mix of thinkers serving as guides along the journey. Influenced by Cooperrider’s call for an appreciative inquiry into the tragic as well as the ordinary and extraordinary, a deep dive is undertaken into the following questions:

Why and for whom do Emiratis and expatriates sustain their pursuit of excellence?

Why and how do Emiratis seek to engage expatriates in this pursuit?

Why are expatriates initially charmed but often prematurely ‘exit’ as this engagement runs its course?

Where in some of the stories told about Sheikh Zayed can be found a more life-giving purpose?

The journey eventually returns home by discussing how it influenced the formulation of a philosophy to guide the strategic process in my business school and could be relevant to other academic ‘place shapers’ seeking cross-cultural enrichment.

Authors: Park Hyung-Jin , Kang Taeuk , Chen Hui-chuan
Published: January 2024

In order to better understand how team composition is related to performance, this research investigates new product development (NPD) team composition and performance based on the individual team member’s knowledge rather than the function to which he or she is currently assigned. A survey of 174 technology firms in Korea, rated as “excellent” companies, shows that the inclusion of multi knowledge members with both marketing and technological knowledge in NPD teams significantly improves innovativeness and time efficiency in comparison to NPD teams without such diverse membership. These findings help illuminate previous contradictory findings in the NPD literature and show the important role of multi knowledge members in NPD performance for senior managers to consider when staffing such teams.

Authors: Chen Alexander , Rodrigues João , Elkhouly Sayed ElSayed , EIDayem Mohamed Abd
Published: January 2024

The global rise of electronic payment services necessitates understanding the factors shaping adoption and usage patterns in Egypt, experiencing rapid growth in e-payment and economy. The implications of the interval’s perception of the COVID-19 pandemic and vaccination are noteworthy. To explore these dynamics, a survey was conducted among students and faculty at a public University in Cairo, Egypt. We examined e-payment adoption using frequency of usage, money spent, percentage of expenditures, and an aggregated measure. Among demographics, working status and income had more influence than age, gender, and education. Regression models showed that gender, income, perceived ease of use, perceived risk, and social influence significantly predicted various dependent variables. However, perceived usefulness, incentives, perceived trust, and vaccine importance had limited relevance in e-payment adoption post-COVID-19. Given the limited sample size, further research is recommended.

Cardiorenalis-metabolikus szemlélet az orvoslásban – gondolatok, tudnivalók az új ajánlások nyomán az SGLT-2-gátlókkal és GLP-1-receptor-agonistákkal kapcsolatban
Authors: Wagner László
Published: January 2024

A 2-es típusú cukorbetegség gyakori szövődményei a krónikus veseelégtelenség és a krónikus szívelégtelenség. A krónikus veseelégtelenség és a krónikus szívelégtelenség azonban egymás kialakulását és romlását is segíthetik, illetve korábban és súlyosabban jelentkezhetnek cukorbetegség esetén. Továbbá, a krónikus vese-, illetve szívelégtelenség esetén a 2-es típusú cukorbetegség is gyakrabban fordulhat elő. Mindezekhez gyakran társul atheroscleroticus cardiovascularis betegség, illetve hypertonia. A 2-es típusú cukorbetegség kezelésében bevezetett SGLT-2-gátlók és GLP-1-receptor-agonisták kardiológiai kimenetelre vonatkozó biztonságossági vizsgálatai kapcsán kiderült a kardioprotektív hatások mellett vesevédő hatásuk is. Az SGLT-2-gátlók kifejezett kardio- és nefroprotektív előnyt mutattak – 2-es típusú diabetes fennállása nélkül is, míg a GLP-1-receptor-agonisták 2-es típusú cukorbetegség jelenléte esetén bizonyultak jótékonynak. A nevezett betegségek konkordáns előfordulása és az említett szerek pleiotrop hatásai alapján felmerül az átfedés a háttérben álló patomechanizmusok és a lehetséges terápiák között. E betegségek népegészségügyi szinten jelentenek problémát, emiatt felismerésük és kezelésük cardiorenalis-metabolikus szemléletet igényel, interdiszciplináris összefogással. Ennek megvalósulása közös munkafolyamat-modell létrehozását sürgeti, amely a közvetlen betegellátástól kezdve a szakmai társaságok közös irányelveinek megjelentetéséig integratív hozzáállást tesz szükségessé.

Social work involving child protection investigations is extensive within social services. The largest proportion of investigations are initiated due to reports of concern. Between the years 2010 and 2021, national statistics indicates that reports of concern increased by 200 percent. This article analyses the social services’ handling of child protection investigations initiated due to concerns about violence. The article is part of a larger study of privatisation in child protection investigations in six municipalities, with comparisons between investigations carried out by municipally employed social workers and private consultants. A high proportion of the investigations examined were initiated due to concerns about violence. The article analyses child protection investigations regarding 70 children, where the reports of concern contain information about violence, either concern about violence against the child or concern that the child experienced violence in close relationships. The article is based on qualitative and quantitative content analyses of the investigations and interviews with professionals. The results show that violence could tend to disappear in the documentation during the investigation process. The investigator could reformulate the questions that guided the investigation and reformulate the statements about violence from one person (father) towards another person (mother) into parental “conflicts”. Instead of a focus on violence, the focus of the investigation could be directed towards the parents’ own problems or the child’s behaviour. One explanation could be that, according to the reports of concern, children who were exposed to violence did not always have the opportunity to express themselves in safe and secure ways during the investigation process. The study shows differences between investigations carried out by private consultants and employed social workers in terms of children’s participation and the extent to which investigations led to any intervention.

Foxg1 is a key regulator of the early development of the vertebrate forebrain and sensory organs. In this study, we describe for the first time three foxg1 paralogues in lamprey, representative of one of two basally diverged lineages of vertebrates—the agnathans. We also first describe three foxg1 genes in sterlet—representative of one of the evolutionarily ancient clades of gnathostomes. According to the analysis of local genomic synteny, three foxg1 genes of agnathans and gnathostomes have a common origin as a result of two rounds of genomic duplications in the early evolution of vertebrates. At the same time, it is difficult to reliably establish pairwise orthology between foxg1 genes of agnathans and gnathostomes based on the analysis of phylogeny and local genomic synteny, as well as our studies of the spatiotemporal expression of foxg1 genes in the river lamprey Lampetra fluviatilis and the sterlet Acipenser ruthenus. Thus, the appearance of three foxg1 paralogues in agnathans and gnathostomes could have occurred either as a result of two rounds of duplication of the vertebrate common ancestor genome (2R hypothesis) or as a result of the first common round followed by subsequent independent polyploidizations in two evolutionary lineages (1R hypothesis).

The Effect of pH on the Viscoelastic Response of Alginate–Montmorillonite Nanocomposite Hydrogels

Ionically cross-linked alginate hydrogels are used in a wide range of applications, such as drug delivery, tissue engineering, and food packaging. A shortcoming of these gels is that they lose their strength and degrade at low pH values. To develop gels able to preserve their integrity in a wide range of pH values, Ca-alginate–montmorillonite nanocomposite gels are prepared, and their chemical structure, morphology, and mechanical response are analyzed. As the uniformity of nanocomposite gels is strongly affected by concentrations of MMT and CaCl2, it is revealed that homogeneous gels can be prepared with 4 wt.% MMT and 0.5 M CaCl2 at the highest. The viscoelastic behavior of nanocomposite gels in aqueous solutions with pH = 7 and pH = 2 is investigated by means of small-amplitude compressive oscillatory tests. It is shown that Ca-alginate–MMT nanocomposite gels preserve their integrity while being swollen at pH = 2. The experimental data are fitted by a model with only two material parameters, which shows that the elastic moduli increase linearly with a concentration of MMT at all pH values under investigation due to formation of physical bonds between alginate chains and MMT platelets. The presence of these bonds is confirmed by ATR-FTIR spectroscopy. The morphology of nanocomposite gels is studied by means of wide-angle X-ray diffraction, which reveals that intercalation of polymer chains between clay platelets increases the interlayer gallery spacing.

En la pandemia Covid 19, el sector textil, abordó con desigual efectividad su producción y venta, enfrentando el desafío de crear nuevos productos, y hacer frente a problemas de abastecimiento, confinamiento y esfuerzo por permanecer en el mercado, pues el uso de prendas livianas se redujo significativamente. El objetivo del estudio es analizar los efectos postpandemia, en el desempeño del sector industrial textil de ropa liviana, periodo 2020-2021 en Ecuador, mediante enfoque mixto, análisis documental de datos oficiales, y aplicación de la prueba estadística T o test de media, que permitió determinar las ventas del sector. Los principales hallazgos establecen notable impacto, con decrecimiento de ventas, sumado, falta de apoyo e incentivos por parte del gobierno, a diferencia de lo actuado con otros sectores, además, la competencia de productos importados a bajo costo, ocasionando una represión que provocó que la balanza comercial se desestabilice y existan pocas alternativas compensatorias.

El cultivo de limón es una actividad importante en la parroquia Riochico del cantón Portoviejo, estudios anteriores no han logrado determinar el proceso de producción, la cadena de comercialización y la rentabilidad hasta llegar al consumidor final. El objetivo de la presente investigación es analizar la producción y comercialización del limón sutil en la parroquia Rio chico y los efectos causados en la economía de productores. Se aplicó el estudio de caso Bestlog basado en la entrevista a productores seleccionados a través de una muestra no aleatoria preferencial y el método de observación, recopilando información sobre la cadena del limón. Se realizó la caracterización de la cadena del limón, facilitando información del manejo de fincas para aplicar estrategias que generen un mejor rendimiento en producción y rentabilidad. Los resultados muestran productores utilizando técnicas de producción que impiden mejor desarrollo y mayor rendimiento, recomendándose mejor tecnificación a través del manejo integral del cultivo. La comercialización es deficiente en la forma realizada, motivo que propone alternativas de negociación, apertura de nuevos mercados o darle valor agregado a la fruta.

En los programas de inseminación artificial (IA), las repeticiones del celo y las pérdidas embrionarias (ME) y fetales son causas importantes de la baja eficiencia reproductiva en los climas cálidos. Esta revisión bibliográfica tiene como objetivo mostrar las causas y estrategias para disminuir las pérdidas de la preñez en la vaca. En el ganado bovino, la tasa de fertilización es alta y ocurre aproximadamente entre el 75 al 90% de las hembras inseminadas. Las mermas embrionarias se producen en más del 25% de los servicios y de ellas la mayor proporción se produce, entre 15 a 17 días del servicio y las seis semanas de inicio de la preñez. Los procedimientos biotécnicas utilizados para prevenir las repeticiones del celo y la mortalidad embrionaria y fetal tales como: el uso de hormonas exógenos que incluyen la progesterona, los estrógenos, la hormona del crecimiento, la gonadotropina coriónica humana, los factores de liberación hormonal y el alfa interferón recombinante con el fin de potenciar las funciones del cuerpo lúteo e inhibir el mecanismo de la luteólisis. Otros procedimientos incluyen la aplicación de diversos procedimientos biotécnicas de sincronización y resincronización del celo para mejorar la eficiencia de los servicios de IA y corregir la baja eficiencia en la detección del celo. La suplementación alimentaría con grasa no saturada y sustancias antioxidantes y medidas de manejo para reducir el impacto del estrés del calor. Estos procedimientos pueden contribuir a mejorar la fertilidad del ganado bovino en climas cálidos.

Purpose : Debriefing is essential for the simulation practice, but the educational varies depending on the debriefing guide. The purpose of this study is to present the effects of attempting debriefing for meaningful learning (DML) for the simulation practice on the critical thinking disposition, problem-solving processes, learning self-efficacy and debriefing experience scale. Methods : This study is based on the single group pre-post test experimental design study, with 58 fourth graders of nursing students were targeted. The application of DML for the simulation practice was conducted for 7 weeks on the subject of nursing care after gastric cancer surgery was completed from May 8 to June 16, 2023. The collected data were analyzed using SPSS 27.0 through the frequency, percentage, mean, standard deviation and paired t-test. Results : After DML, the results present that there were significant differences in the problem-solving processes(t＝-2.79, p＝.007) and learning self-efficacy(t ＝-3.90, p＜.001), while the critical thinking disposition(t＝-1.61, p＝.111) demonstrated no significant differences. Conclusion : In the simulation-based education, debriefing with DML can be used as an effective strategy, and the comparative and repetitive studies using other debriefing will be needed in the future.
