Published: June 2024

Angka kematian ibu (AKI) di Indonesia masih tinggi, yang sebagian besar disebabkan oleh komplikasi selama kehamilan, termasuk hipertensi. Pengobatan hipertensi pada ibu hamil bertujuan untuk mengontrol tekanan darah tanpa membahayakan kesehatan janin. Namun, biaya pengobatan hipertensi cenderung tinggi, sehingga perlu dilakukan penelitian farmakoekonomi untuk membandingkan efektivitas biaya obat antihipertensi yang umum digunakan. Penelitian ini menggunakan metode observasional analitik dengan pengumpulan data retrospektif dari pasien ibu hamil penderita hipertensi yang dirawat jalan di RSUD Bandung Kiwari. Sampel dibagi menjadi tiga kelompok pengobatan: dopamet (metildopa 250 mg), nifedipin 10 mg, dan adalat oros (nifedipin 30 mg). Analisis minimalisasi biaya (AMiB) digunakan untuk membandingkan biaya rata-rata per pasien dari masing-masing kelompok pengobatan. Hasil penelitian menunjukkan bahwa biaya rata-rata per pasien untuk pengobatan dengan nifedipin 10 mg lebih rendah (Rp165) dibandingkan dengan dopamet (Rp317) dan adalat oros (Rp4.247). Kesimpulannya, dari perspektif rumah sakit, penggunaan nifedipin merupakan pilihan yang lebih ekonomis dalam pengobatan hipertensi pada ibu hamil.

Published: June 2024

Lack of attention from the company and ship's crew to work safety. It can be seen from the work safety equipment supplied by the company for crew members who only use helmets and gloves, and also some crew members who carry out overhaul work on the main engine do not wear safety shoes. In dealing with and preventing work accidents on ships, especially in the engine room, workers (crew) should be equipped with Personal Protective Equipment (PPE). Lack of familiarization as new crew members, lack of skills, experience and knowledge of crew members in the engine section regarding work safety. It is interesting to note that experienced crew members are less likely to experience an accident than crew members who are new to carrying out their work.  This is because experience and length of time working in a particular skill plays a role in avoiding accidents. Based on experience, many incidents ranging from near misses to serious accidents occur on ships. Based on this, it is also something that is very important for planning safety programs, so that possibilities and losses resulting from these events can be prevented. Case Study, the fall of cylinder piston no. 3 main engines. KM. INTAN DAYA almost fell on one of the oilmen during an overhaul which caused damage to the material or piston. This is due to the lack of introduction of new crew members to awareness and the dangers of other work accidents.

Undang-Undang Nomor 6 tahun 2014 tentang Desa memberikan tanggungjawab yang besar bagi pemerintah desa, namun pemberian tanggungjawab yang besar tersebut tidak dibarengi dengan penyiapan sumber daya manusia yang baik, sehingga tata kelola pemerintahan yang baik dilingkungan pemerintahan desa masih jauh dari harapan. Hal ini terlihat dari masih adanya aparat desa yang kurang disiplin dalam menjalankan tugas dan tanggungjawabnya dan di sisi lain, pemberian otonomi desa melahirkan praktik korupsi baru di tingkat desa. Hasil penelitian menunjukkan bahwa prinsip good governance telah diterapkan dalam penyelenggaraan pemerintahan desa, sedangkan faktor yang menghambat pelaksanaan good governance dalam penyelenggaraan pemerintahan desa adalah partisipasi masyarakat, sumber daya manusia, dan disiplin aparat desa. Adapun faktor pendukung penerapan good governance dalam penyelenggaraan pemerintahan desa adalah adanya kerjasama dan komunikasi. Kata Kunci: pemerintah desa, tata kelola, good governance

Published: June 2024

The implementation of advanced digital, intelligent production technologies and robotic systems contributes to the achievement of the goal set for the agro-industrial complex for transition to a highly productive, environmentally friendly agricultural economy. Taking this into account, as well as the global trends in the development of unmanned mobile vehicles, three conceptual models for the development of unmanned mobile power tools are proposed: the creation of universal unmanned mobile vehicles of various traction classes and power based on commercially available tractors (conceptual model A), the creation of universal unmanned low-power mobile devices working in groups (conceptual model B) and the creation of energy modules (conceptual model C). In order to determine further prospects for their use, theoretical studies have been carried out on the issue of evaluating the productivity of agricultural aggregates in combination with unmanned mobile vehicles of the proposed conceptual models. The research was carried out on the basis of existing well-known methods and formulas for determining productivity. The analysis of factors affecting the productivity of an agricultural unit during field operations shows that when using unmanned mobile vehicles, an increase in the productivity of the unit can be ensured by increasing the utilization factor of the width of the grip and the time of main work by eliminating the time spent on rest and personal needs of the operator, reducing the time spent when turning the unit at the end of the rut. The developed methodological approaches to the issue of calculating the productivity of agricultural aggregates in combination with unmanned mobile agricultural vehicles made it possible to assess the increase in the productivity of aggregates using unmanned mobile means of the proposed conceptual models. The use of unmanned mobile vehicles of the considered conceptual models can increase the replaceable productivity of units for continuous cultivation compared with traditional manned tractors by a level from 3 to 24 %.
Static characteristic of angular velocity measuring transducer for adaptive control systems of hydraulic drives
Authors: Golubovsky V. V. , Simanin N. A. , Konovalov V. V.
Published: June 2024

The aim of the research is to obtain the static characteristic of the angular velocity measuring transducer of the developed design and to determine its design parameters. The research methodology provides theoretical substantiation of the static characteristic of the proposed angular velocity measuring transducer with inertial flap and nozzles. The paper considers the principle of operation of various designs of measuring transducers of angular velocity with inertial masses. The variant of constructive execution of angular velocity measuring transducer with inertial flap and nozzles is substantiated, for which the static characteristic is obtained. On the basis of the obtained expressions the main design parameters of the device are determined. The methodology of calculation of static characteristic of angular velocity measuring transducers in the adaptive control system of hydraulic drive is considered. The obtained expression of the static characteristic of the proposed design of the angular velocity measuring transducer connects the external disturbing influence (angular velocity) and the pressure drop in the interthrottle chambers in the steady-state mode of operation. The recommended parameters of the elements of the angular velocity transducer are: nozzle orifice diameter in the range of 0.5–1.5 mm, nozzle face diameter in the range of 1.2–1.5 nozzle orifice diameter, flap stroke up to 0.1 nozzle orifice diameter. It should be noted that at diameters of permanent throttle and nozzle orifices less than 0.5 mm, as well as at the flap movement less than 0.02 mm, obliteration may occur, i.e. overgrowing of resistance passage sections by polarised liquid molecules, which breaks the performance of the angular velocity transducer. The obtained expression of the static characteristic of the proposed design of the angular velocity transducer with an inertial flap and nozzles allows us to determine the design parameters of its elements and, on their basis, the dynamic characteristics.

Authors: Bozkurt Bayram , Kara Mevlüt
Published: June 2024

This study examines the mediating role of teachers’ perceived administrative support in the relationship between principals’ social justice leadership behaviors and teachers’ trust in principals. The sample of the study, which was designed in the relational survey model, consists of 903 teachers working in public schools in a metropolitan city in Southeast Turkey. In the context of the research model, the SPSS Process Macro (Model-4) application developed by Hayes (2018) was used to determine the mediation effect. Because of the analysis of the research data, it was determined that the social justice leadership behaviors exhibited by school principals predicted both teachers’ trust in the principal and teachers ’ perceived administrator support positively and statistically significantly. On the other hand, it was concluded that perceived administrator support plays a mediating role in the relationship between principals ’ social justice leadership behaviors and teachers ’ trust in principals. In this context, it can be staded that if school administrators’ social justice leadership behaviors increase, both the administrator support perceived by teachers and their trust in the principal will increase.

The Effects of Macroeconomic Variables on the BIST 100 Index: ARDL and NARDL Approaches
Authors: Algoni Mohammed , Ivrendi Mehmet
Published: June 2024

The objective of this research is to analyse the signal, magnitude, and significance of both symmetric and asymmetric effects of interest rate, taxes, exchange rate, oil price, and gold price on the Turkish stock market (BIST100). The autoregressive distributed lag (ARDL) technique was used in both linear and non-linear formats. The F-Bounds test of the linear ARDL test suggests that the variables do not exhibit long-term integration. Nevertheless, the F-bounds test of the nonlinear ARDL (NARDL) test confirms the presence of cointegration among the variables. Therefore, the research heavily relies on the NARDL model. The empirical evidence indicates the long-term influence of the exchange rates rate, gold price, and interest rate on the BIST100 index is asymmetric. Additionally, the asymmetrical effects of interest rates, taxes, exchange rates, oil prices, and gold prices in the short term have an impact on the BIST100.

Research results and ways of applications of the electromagnetic forces method in metalworking production for the operations of parts hardening, dry-lubricant coating processes, slurry waste upgrading in grinding production, are presented. The essence and means of method techniques are revealed. Analytical dependencies, recommended modes and conditions for performing magnetodynamic treatment under technological operations are given. It is found that the main energy deposition impact factor as a target exposure for the object under treatment or waste management is a magnetically vibrating layer formed in devices that create a rotating electromagnetic field and provide an operational benefit due to the occurrence of various physical effects and the intense movement of particles of a dispersed medium. Design and technological solutions of technological systems have been developed using devices with a rotating electromagnetic field, allowing for high technical and economic efficiency to provide: hardening of slender parts having long length, as well as parts with hard-to-reach internal cavities; slurry waste management in grinding production in an attempt to obtain processed raw materials for powder metallurgy, tool and foundry production. It is shown that electromagnetic forces method is quite effective for applying dry-lubricant anti-friction coatings on the surface of parts, making it possible to form traces of shock-pulse action of indentors on the surface of the treated spherical and elliptical shape , which prove the formation of a lubricant film; allowing height reduction of the irregularities and increasing the radius of apex of salient roundness together with the true contact area between the coating and the metal surface ; ensuring the adhesion of the coating over the entire contact area of the indenter with the metal surface; providing the uniformity of the application of a lubricating film on the surfaces of parts having various complex shapes.
Ethnography of Science: A Literature Review
Authors: Diastuti Indah Mei , Ahmadi Anas
Published: June 2024

The study of how certain communities or ethnic groups perceive and comprehend science is known as ethnoscience. This discipline investigates how various communities use, comprehend, and interpret science. While some communities could be more skeptics and hesitant to adopt new science and technology, others might be more receptive to both. Beliefs, culture, and religion may all have an impact on how society applies science. In addition, ethnoscience investigates the ways in which science affects society. An educational strategy called ethnoscience links the actual knowledge of a society to scientific understanding . It is a new type of ethnography that allows cultural researchers to develop grassroots ideas based on ethno and folk without necessarily accepting western cultural theories that may be irrelevant.Ethnoscience is an interdisciplinary field of study that combines the principles of ethnography and science. This field aims to understand the relationship between culture and science. This article discusses the origins of ethnoscience, the scope of the field of ethnoscience studies, and the future of ethnoscience. Ethnoscience encompasses a variety of scientific disciplines, including anthropology, sociology, history, and philosophy of science. One of the main research areas in ethnoscience is the study of indigenous knowledge systems. Ethnoscience also studies the relationship between science and religion. Ethnoscience can help us understand how scientific knowledge is produced and used in different cultural contexts.

The feed industry plays an important role in the economy, as well as in stock investment activities. The performance of feedstock companies is highly dependent on internal and external conditions. This condition becomes an interesting thing to study related to the effect of stock returns. The method used in this study is panel data regression, with data samples from 4 companies with a quarterly period from 2017 to 2021. The quantitative approach uses an econometric approach to determine the financial and macroeconomic performance factors on stock prices in the animal feed sub-sector. The financial performance variables used are Cash Ratio (CashR), Debt Equity Ratio (DER), Net Profit Margin (NPM), Inventory Turnover (ITO), and macroeconomic variables, namely the rupiah exchange rate against the US dollar (exchange rate), international soybean prices, the price of local corn. The results show that the ratio of profitability, liquidity, solvency, and exchange rates is an important part that must be considered before investing in a feed company. Industry NPM performance is 3 percent, where the company with the highest NPM is CPIN and the lowest is SIPD. The industry average CashR performance is 0.24, with the highest CashR company CPIN and the lowest MAIN. The industry's ITO performance is 4.06 times, with the company's highest ITO ratio being CPIN and the lowest being JPFA. The industry DER value is 1.10, with the highest DER company CPIN and three other companies (JPFA, MAIN, SIPD) below average.

This article investigates the infrequently used vocabulary in the Batu Belah area through a combined methodological approach of observation and survey. By observing linguistic interactions and administering surveys to local inhabitants, this study aims to identify and analyze words and phrases that are rarely employed in everyday discourse within the region. Through a systematic analysis of survey responses and observational data, we delve into the socio-cultural, historical, and geographical factors contributing to the usage patterns of these lexical rarities. The findings not only provide insights into the linguistic landscape of Batu Belah but also offer a deeper understanding of the preservation and evolution of regional dialects. This research contributes to the broader discourse on linguistic diversity and sheds light on the intricate relationship between language, culture, and identity in the Batu Belah area.
Inhibitory effect of plant essential oils on controlling Alternaria species
Authors: Erdoğan Oktay
Published: June 2024

The use of natural products in the control of fungal diseases in plants is considered an alternative to synthetic fungicides due to their less negative effects on the environment. In this study, in vitro inhibitory effect of plant essential oils (PEOs) of black cumin, cumin, chamomile, cedarwood, and ginger were investigated for controlling two species of Alternaria, including Alternari solani and Alternaria alternata on tomato and cabbage under in vitro conditions, respectively. Aiming to evaluate the mycelial growth of the pathogen, mycelial discs were placed in Petri plates with 0, 500, 1000, 1500, 2000, and 2500 μL/L of PEOs. The experiment was carried out in a randomized plot design with three replications. Chemical analysis of PEO components were determined by Gas Chromatography and Mass Spectrometry methods. A total of 69 chemical compounds were determined in five different PEOs. As the main chemical compounds, Cuminaldehyde was detected in cumin PEO, Sesquithujene was found in ginger PEO, and Eucalyptol (1,8-cineole) was determined in black cumin, chamomile, and cedarwood PEOs. All five PEOs were found to inhibit the growth of Alternaria species in a dose-dependent manner, whereas cumin EO was determined more inhibitory effect against A. solani and A. alternata. Cumin PEO showed the highest effect against Alternaria species because it contains a Cuminaldehyde chemical compound. The lowest inhibition percentage was found in chamomile PEO compared to other PEOs. This study suggested that cumin PEO has the potential as an antifungal agent for controlling of Alternaria diseases.
Historical Philosophical Analysis of Social Reality
Authors: Tetenkov Nikolay
Published: June 2024

The philosophical analysis of social reality is necessarily carried out in the ratio “man-society”. After all, a person can realize his essence only in society, therefore, the subject of social philosophy is society as an integral system. Social philosophy as a branch of philosophy considers and explains social phenomena and processes at the most general level, and this allows us to present society as a system capable of self-development and self-reproduction. Based on the accumulated knowledge over the entire history of studying this problem, a number of philosophical concepts have been formed regarding the interpretation of the concept of society: naturalistic, sociological, psychological, active, dialectical-materialistic, praxeological, etc.

Published: June 2024

The Survey Quality Predictor (SQP) is an open-access system to predict the quality, i.e., the reliability and validity, of survey questions based on the characteristics of the questions. The prediction is based on a meta-regression of many multitrait-multimethod (MTMM) experiments in which characteristics of the survey questions were systematically varied. The release of SQP 3.0 that is based on an expanded data base as compared to previous SQP versions raised the need for a new meta-regression. To find the best method for analyzing the complex data structure of SQP (e.g., the existence of various uncorrelated predictors), we compared four suitable machine learning methods in terms of their ability to predict both survey quality indicators: LASSO, elastic net, boosting and random forest. The article discusses the performance of the models and illustrates the importance of the individual item characteristics in the random forest model, which was chosen for SQP 3.0.
