Pengaruh ketidakseimbangan tegangan pada suplai daya listrik terhadap kecepatan putaran dan efisiensi motor induksi 3-fasa
Authors: Kurnia Mutiara Zahra , Kastawan I Made Wiwit , Raharjo Parno
Published: August 2023

Motor induksi 3-fasa akan beroperasi pada keadaan ideal ketika disuplai dengan sumber tegangan 3-fasa sinusoidal yang memiliki tegangan per-fasa dengan frekuensi sama, magnitudo sama serta saling berbeda fasa 120°. Namun dalam keadaan riilnya motor induksi 3-fasa seringkali beroperasi dalam kondisi tak ideal, sebagai akibat ketidakseimbangan tegangan pada suplai daya listrik yang dapat mempengaruhi unjuk kerjanya. Dalam kegiatan penelitian ini dilakukan pengujian motor induksi 3-fasa dengan dua kondisi ketidakseimbangan tegangan suplai berbeda yaitu ketidakseimbangan magnitudo serta ketidakseimbangan magnitudo dan fasa. Motor induksi 3-fasa disuplai melalui satu buah auto transformator tiga-fasa, satu buah auto transformator satu-fasa serta sebuah kapasitor daya yang dipasang pada salah satu fasa. Keadaan ketidakseimbangan magnitudo tegangan yang dibuat pada pengujian ini adalah sebesar 3%, sementara ketidakseimbangan beda fasanya adalah sebesar 2?. Hasil pengujian menunjukkan terjadinya penurunan putaran dan efisiensi pada motor induksi 3-fasa. Semakin tinggi nilai ketidakseimbangan suplai daya listriknya maka putaran dan efisiensi motor induksi 3-fasa semakin menurun. Penurunan kecepatan putaran dan efisiensi tertinggi terjadi pada kondisi ketidakseimbangan magnitudo 3% dan ketidakseimbangan beda fasa 2? dengan kondisi pembebanan 70%. Putaran nominal motor turun dari 2989 rpm ke 2953 rpm sehingga terjadi penurunan putaran sebesar 36 rpm dengan slip sebesar 1,20 %. Penurunan efisiensinya adalah sebesar 5%, turun dari 82% menjadi 77%.

Published: August 2023

Histórica y psicológicamente, la noción de la relación amorosa, se transforma y cambia con cada época y según la región. En este sentido, el presente trabajo se centra en definir el concepto de amor en la danza del Huayño, baile más representativo y antiguo de la cultura Aymara. Para responder a los objetivos, como herramienta cualitativa de estudio, se realizan entrevistas en profundidad a directores de grupos de danza escénica folclórica boliviana que llevan más de veinticinco años de trayectoria como estudiosos de la danza. En la danza del Huayño, durante la época precolonial, el amor es simplemente fatuo o necio, pues estaba ligado en mayor medida a la pasión y en menor medida, al compromiso. En la época contemporánea, el significado de amor está predominado por el sentido del compromiso y de la intimidad, es entonces un amor de compañeros. La notable división de las épocas precolonial y contemporáneo y la evolución del concepto de amor entre éstas, marcadas por la llegada de la colonización española, es el resultado de esta investigación realizada en torno a la danza del Huayño.

Authors: Bazzari Firas , Bazzari Amjad
Published: August 2023

Alzheimer’s disease (AD) is a multifactorial neurodegenerative disorder linked to multiple genetic and environmental factors. Despite its complex pathology and still undetermined etiology, a number of factors have been found to be closely associated with the incidence of AD. Although the molecular mechanisms linking many of these factors with AD are unclear and not necessarily causative, their identification and control might be key preventative measures. Cardiovascular diseases, diabetes, obesity and other life-style habits are recognized as established risk factors for AD. Other emerging factors investigated as potential contributors to the overall risk of dementia include anemia, obstructive respiratory diseases, vitamin D deficiency, thyroid imbalance, inflammation and depression. This review summarizes established risk factors; it also provides an insight into emerging factors as modifiable elements, the control of which may reduce the risk of AD and dementia.

Authors: Mishchanka V. N.
Published: August 2023

The results of modeling the properties of graphene modified with fluorine atoms are presented. The creation of modern semiconductor devices requires the introduction of new materials. Graphene is one of them that is of interest to researchers. The addition of fluorine, hydrogen, and other chemical elements to graphene makes it possible to create its modifications. On this basis, it is possible to develop semiconductor devices and devices with improved output characteristics. The basic characteristics of graphene modification with the use of fluorine atoms, namely, the band diagram, the dependences of the density of state (DOS parameter) of electrons and holes on the energy value, were obtained by first-principles modeling. The dependences of charge carrier mobility on temperature are determined for the iterative solution of the Boltzmann transport equation The dependences and parameters obtained for fluorinated graphene can serve as a basis for creating new heterostructural devices containing layers of modified graphene and other semiconductor materials.
Working together. A longitudinal study on the management of deontic rights in joint activities
Authors:   , Jones Adam
Published: August 2023

Everyone at some point in their life enters a new community. People enter new schools, they start new jobs, they pick up hobbies and make friends. Entering a new community of practice can be an incredibly complex, exciting, and sometimes frightening endeavor. The object of this thesis is to examine the trajectory of the newcomer in workplace settings. Specifically, this thesis focuses on cooperation and resistance, and how newly acquainted co-workers navigate to delicate issues when working together. Power and cooperation are conceptualized in this thesis as participants deontic rights, and the ability to decide on one’s own actions or the actions of another. Drawing on ethnomethodologically informed and longitudinal conversation analysis (CA) this study looks at speakers’ multimodal practices for navigating through joint courses of action in a semiotically rich, workplace environment. Data consists of audio-video recordings collected longitudinally of a newcomer and co-worker working in a physics laboratory. The analytical focus of the thesis focuses on (1) the organizational structure of initiating, engaging, and delegating responsibilities in joint actions, (2) the practices for displaying resistance to joint actions through disagreement and non-compliance, and (3) how participants alter a recipient’s ongoing actions to resolve troubles. Using multimodal conversation analysis, these chapters document the complex, assemblies of language, multimodal resources, and objects at different levels of sequential and synchronous organization to accomplish the above actions. Documenting how participants recipient design their actions at various levels of joint activities, shows the local, temporally emergent routines that arise out of the practical need to conduct coordinated workplace interactions. Furthermore, by adopting a longitudinal approach, the study also shows how the management of deontic rights is a longitudinal, interactional accomplishment that changes with participants shared interactional histories and evolving social relationships. The study presents a novel contribution to longitudinal CA, multimodal interaction, and workplace studies while providing further empirical evidence for the fundamentally rich, socially and materially distributed nature of social interaction.
Analyzing Domestic Violence in the Qur’an through Hermeneutics of H.G. Gadamer: Views of Amina Wadud
Authors: Maksum Imam , Huda Sokhi , Suadi Suadi , Hananta Yor
Published: August 2023

This study is motivated by interpretation and followed by an understanding of the position of men and women, which discredits one party. This research focuses on the thoughts of the philosopher Amina Wadud, a reformist Muslim thinker, in interpreting the Qur'an with her work Qur'an and Women. The purpose of this study is to discuss domestic violence further. This research is qualitative; the data were obtained from library sources, with the primary source from the Qur'an and Women. Data processing is done by grouping, reduction, and codification. Meanwhile, in data analysis, Hans-Georg Gadamer's Hermeneutical approach is that of intelligence subtility–how to understand (das Verstehen), explicandi subtility–how to explain (dem Auslegen), and applicandi subtility–how to apply (das Anwenden). The research results obtained in this article demonstrate that the interpretation of Amina Wadud does not violate Islamic teachings. Values and forms of deconstruction of understanding are by and refer to the Qur'an. Amina Wadud said that the Qur'an, in substance, never teaches the use of violence to solve family problems, especially in marital relations. The meaning that can be concluded is deliberation in solving issues by placing husband and wife in the same position because all human beings are equal before God.

The communication between microcontrollers and PLC has become an important technology development that needs to be enhanced. One of the reasons for the communication between these two devices is to facilitate the input process of data or information from sensors, which are responsible for detecting or measuring specific parameters. Not all sensors can be directly read by PLC, as some sensors have their own communication protocols or specific libraries that are not directly supported by PLC. Microcontrollers are often used as intermediaries between sensors and PLC. Microcontrollers can read sensor data and then convert it into a format that can be understood by PLC. Microcontrollers can perform flat processing tasks such as conversion and status evaluation to provide more relevant data, and then send this data to the PLC through a compatible communication protocol. In this study, the communication protocol used is the Host Link serial communication using the C-mode Command method. The communication testing conducted using 10 different data samples resulted in accurate values with an error percentage of 0%.
Pengaruh Metode Quenching dan Tempering Terhadap Kekerasan Material Hot rolled Plate (HRP) Steel
Authors: Nurhidayat Akhlis Rahman Sari , Laksana Nur Akhlis Sarihidaya , Yurianto Yurianto
Published: August 2023

Hot rolled plate steel as a material to be used for steel armor needs to have the characteristics of a high hardness value. Medium carbon steel as the basic material is quenched at a temperature of 900 oC and tempering is carried out at a temperature of 125 oC and 175 oC with a holding time of 30 minutes. The Ms value is a benchmark for changes in martensite which is influenced by the constituent elements of the material. The use of water as a quench medium changes the structure of austenite to martensite. The martensite structure that occurs increases the optimum hardness value in HRP Steel material. The tempering process carried out above the Ms value causes a decrease in the hardness value. The highest hardness value was obtained in the quenching process with 542 HV which was influenced by the distribution of martensite. The decrease in hardness value occurs due to the tempering process, the average hardness value at temper 125 oC is 524.4 HV and 175 oC is 524 HV.

Cooking ware that is made of aluminum is used in different nations, particularly developing nations, and are a free source of aluminum. Due to its possible harmful effects on human health, aluminum is acknowledged as a public health problem. The goal of the current investigation is to evaluate curcumin's (CUR) capacity to decrease aluminium’s toxicity by forming stable complexes. Rhizomes that are sold in the local marketplaces have an 8.5% crude pigment content of CUR. At various pH levels, CUR's maximum absorbance was identified. Citric acid was used as a catalyst to create the CUR-Al+3 combination at various pH levels, which correspond to the rates at which Al+3 was eliminated from the solution. At pH 2.5, 3.0, 3.5, and 4.0, the highly complexation was seen. At such pH levels, the Al+3 elimination was 79.22, 78.28, 79.26, and 79.41%, respectively. The CUR-Al+3 complexes’ stability represent, respectively, 96.94, 96.29, 95.55, and 95.52% of the initial concentration at 25o, 50o, 75o, and 100o C for 60 min at pH value of 2.50. Using Fourier-transform infrared spectroscopy (FT-IR), it has been possible to identify CUR and its complex with Al+3. At varied pH levels, 1.5, 2.5, 3.5, 4.5, 5.5, and 6.5 at boiling point, the leached aluminium from 3 regions of the aluminium cooking ware (Syrian, Iranian and local) was specified. Comparatively to Syrian and local cooking wares, Iranian cooking ware generally leached more aluminum. In comparison to other pH values, the percentages of the elimination of the aluminum that is leached by utilizing the most leaching cookware (Iranian) have been 79.23 and 79.26% at pH values of 2.50 and 3.50, respectively.

Digestive enzyme activities of Yellow Rasbora (Rasbora lateristriata) had been reported, but only focused on a daily feeding strategy. The effect of starvation and refeeding on the growth, body composition, and digestive enzyme activities in Yellow Rasbora has never been reported. This study aimed to know the most efficient feeding strategy for growth, body composition, and digestive enzyme activities of Yellow Rasbora. The experiment was conducted in 20 aquariums using two months old fingerling. Four different feeding strategies were tested; twice feeding a day, one-day starvation and six days refeeding, two days starvation and five days refeeding, and four days starvation and ten days refeeding. The result showed that different feeding strategies had no significant effect on all growth parameters. The result proved that Yellow Rasbora could compensate for starvation through absolute growth, with the highest value achieved in two days of starvation and five refeeding. No significant value was also observed on crude protein, and lipid contents indicate that starvation does not affect the utilization of protein and lipid reserves. This result was consistent with fish condition factors which did not differ among treatments. The feeding strategy did not significantly affect total protease, trypsin, and amylase activities, but significantly affected chymotrypsin, lipase, and alkaline phosphatase activities. All parameter indicated that two days starvation and five days refed duration showed similar values to daily feeding. Therefore, it is concluded that two days starvation and five days refeeding method is the most efficient feeding strategy for Yellow Rasbora cultivation.

Rice-fish farming system that is purposed to maximize land use by adding fish farming to its systems. In the Rice-fish farming system, the fish farm serves as a solution to overcome pests so it can provide benefits for the farmers. Fish farm maintenance is considered to be a solution to reduce farmers expenditures in the use of fertilizers. The reason is in the fish-maintaining process, fish will naturally excrete dirt which has a function as organic fertilizer which will increase the fertility of the waters. The purpose of this study was to determine the composition of phytoplankton as well as the physical and chemical quality of the water in several Rice-fish farming system stations in Panembangan Village so that the condition of the ecosystem can be detected whether it is in good or bad condition. The Results showed that the diversity index value ranged from 0.61-1.99. The uniformity index value was obtained in the range of 0.15 – 0.50 and the dominance index value was obtained in the range of 0.20 – 0.72. While, the four stations still have good water quality, the conditions in the Rice-fish farming system area of Panembangan Village are still suitable for the growth of organisms.

Published: August 2023

In a general suspension system ride comfort and suspension performance are inversely related.Whenever the vibrations are damped in a periodic and slow manner, the ride comfort improves but the suspension performance degrades. This project presents a frequency-based controller for active suspension using the H-infinity algorithm. The implementation includes performing the analysis using a general quarter car model. This is done to reduce the complexity of the model and at the same time helps to carry out the analysis without any compromise. In the implementation, the quarter car model is converted into a state-space model to make further analysis easier. The next part includes the development of a robust controller so that the system response is acceptable even in the case of uncertain input. In the model developed, the output states to be monitored are taken as suspension deflection and body acceleration. The input state to the controller is taken as the actuator force input. Intent of the model development is to mitigate the general trade-off between ride comfort and suspension performance.

This article presents a novel numerical approach aimed at finding a distribution network expansion plan that prevents future congestion and voltage issues. Forecasted duration and intensity of thermal and voltage violation events are used to determine a pool of potential candidates for infrastructure (i.e., line/cable) upgrade, voltage regulator, and energy storage system installations. This is complemented with an algorithm to obtain the minimum-cost list of these candidates that solves all constraint violation events using binary linear programming. This approach is validated using the modified IEEE 33-bus network and a real 1171-bus feeder in the West of Ireland through numerous high-resolution quasi-static time series simulations. Three pools of candidates and three cost projections were considered to explore the method’s sensitivity to different scenarios. Results show that the proposed methodology is a versatile tool for designers, planners and policymakers. The methodology can ensure that the investment plan solves all forecasted violation events. Nevertheless, we show that accepting a marginal degree of violations may be acceptable and would significantly reduce investment costs.
