The Determinants of Capital Structure: Evidence from Indonesia
Authors: Mardani Ronny Malavia , Moeljadi  , Sumiati  , Indrawati Nur Khusniyah
Published: July 2023

Purpose:  This paper aims to examine the determinants of capital structure.
 
Theoretical framework: There is an essential gap in modern finance theory on the issue of corporate debt policy, where contemporary theory cannot explain the company’s choice of capital structure composition (Myers, 1977). Myers (1984) claimed that we have a limited understanding of capital structure. We have no idea how corporations determine whether debt, equity, or hybrid securities to issue. Furthermore, Thies & Klock (1992) claimed that capital structure is one of the most divisive topics in finance.
 
Design/methodology/approach: A hundred and three companies were observed 618 times, applying multiple regression to find out the determinants of capital structure in manufacturing companies in Indonesia from 2011 to 2017.
 
Findings: This study disclosed that five capital structure determinants (firm size, profitability, debt tax shield, growth, and liquidity) significantly affected capital structure. Firm size, debt tax shield, and growth positively correlated with capital structure, while profitability and liquidity negatively correlated with capital structure. Firm size was inequivalent with expectations, indicating that managers take advantage of firm size to increase their debt. Likewise, growth was not analogous with expectations, indicating that the company was taking advantage of its growth opportunities to increase debt. On the other hand, profitability, debt tax shield, and liquidity had the desired direction of the relationship. Furthermore, the other two variables, firm age and business risk, had no significant effect on capital structure, alluding that they were improper variables to explain variations in the sample companies’ capital structure.
 
Research, Practical & Social implications: The study focused on manufacturing companies listed on the Indonesia Stock Exchange, consisting of various industrial sectors and sub-sectors or heterogeneous. Thus, recruiting homogenous samples is recommended to generalize Indonesians’ sub-sector companies. In addition, the findings suggested that the management needed to pay attention to firm size, profitability, debt tax shield, growth, and liquidity to determine the composition of its capital structure.
 
Originality/value: Manufacturing companies listed on the Indonesia Stock Exchange were recruited as the sample of the study. However, the controversies and inconsistencies of the results are still debatable.
Modeling Interest in Visiting Through Expected Values in Tourism at Solok Regency, Indonesia
Authors: Salim Emil , Ali Hapzi , Yulasmi
Published: July 2023

Purpose: This study aims to determine the effect of Digital Marketing, Local Wisdom and Facilities on Tourist Interests in Visiting Tourism in Solok Regency.
 
Theoretical framework: Competition for tourist destinations requires understanding, apart from tourism destinations or tourism-specific factors, the inclusion of factors that affect competition for companies and organizations involved in the production of tourism "products". In other words, a tourist destination is competitive if it can attract and satisfy potential tourists and this competition is determined by tourism-specific factors and broader factors that influence tourism service providers. (Trusov, 2016)
 
Design/methodology/approach: The sample size in this study was adjusted to the Structural Equation Model, which became Structural Equation (SEM). This means that a minimum of 200 samples must be included in the SEM study using the MLE estimation model.
 
Findings: The findings in this study prove that facilities have a significant impact on the interest of visiting tourists. This proves that interest in visiting will increase along with the good facilities offered at a tourist destination, which is because the expectations of tourists who come before visiting a tourist attraction are to get satisfaction or happiness after visiting the tourist attraction.
 
Research, Practical & Social implications: The implicative suggestion from this study is that tourism managers must also prioritize developments that occur in the tourism industry so that tourism objects are not left behind in the face of competition with other tourist objects.
 
Originality/value: The drastic decrease in tourist visits to Solok Regency makes this a gap in this study. So this research focuses on analyzing the factors that are considered relevant to influence the decision to visit, namely product, price and digital marketing. The novelty in this study lies in the object under study, namely all existing tourist destinations with the research subjects being visiting tourists using the Structural Equation Modeling (SEM) approach. The results of this study are expected to contribute to the development of marketing science, especially in the tourism sector.

Effects of Alloying Element and Heat Treatment on Mechanical Properties of Alloy Steels
Authors: Abdullahi Umma
Published: July 2023

The effects of Cr and Ni on three different types of steel with different carbon ratios under constant conditions such as the welding current 120A, voltage 80V, Diameter 10 mm and angle 60 degree was observed. Nickel percentage of up to 0.147% and Chromium 0.083% contributed to affecting the mechanical properties of the steel. Undissolved carbide particles refine the austenite grain size. In the presence of nickel, chromium carbide is less effective in austenite grain refinement than chromium carbide in absence of nickel at temperature below 975°C. Nickel does not produce any austenite grain refinement but presence of nickel promotes the formation of acicular ferrites. It was also found that Ni and Cr as chromium carbide also refines the ferrite grain size and morphology. Cr as chromium carbide is more effective in refining ferrite grain size than nickel. The microstructure of the base metal as a reference material was analysed before heating to support the results of chemical analysis. Nickel percentage of up to 0.147% and Chromium 0.083%. Molybdenum was 0.03% which contributed to affecting the mechanical properties of the steel.Keyword: Alloy steel, Heat treatment, Chromium, Nickel, Grain size

Función de Producción Cobb-Douglas. Una Revisión Bibliográfica
Authors: Mejía-Matute Silvia Raquel , Pinos-Luzuriaga Luis Gabriel , Tonon-Ordóñez Luis Bernardo
Published: July 2023

Para la ciencia económica, el análisis de la función de producción es una práctica generalizada, ya que se la aborda desde el punto de vista microeconómico con el análisis de la teoría de la producción y también desde la perspectiva macroeconómica para explicar en qué medida los cambios en los factores de producción determinan el producto. La función de producción Cobb-Douglas ha sido una de las más aplicadas para medir estos parámetros, que implican a nivel agregado la productividad y crecimiento económico. Entonces, surgió la interrogante de si ¿es realmente esta función apropiada para interpretar las fuentes de crecimiento, así como estimar la productividad de los factores y así conocer el desempeño productivo de un país? Para abordar este problema, se realizó una revisión bibliográfica sistemática que recoge históricamente las más notables contribuciones sobre esta función, aplicada desde aproximadamente cien años. Se analizaron las principales características y supuestos, así como las fuertes críticas que se realizan, teniendo en cuenta el debate del capital-trabajo y la distribución primaria de la renta. Lo cierto es que, sigue aplicándose ahora con modelos econométricos más sofisticados, como panel de datos desbalanceados de los Modelos Generalizados de Momentos.
Estabilidad Económica y Política para América Latina

Published: July 2023

Los albores del siglo XXI han generado varias encrucijadas en el ámbito político, económico, social, tecnológico e incluso académico; de ahí que en América Latina se viva una lucha de poderes basada en intereses partidistas y su consecuente alejamiento de una objetiva visión de futuro para el desarrollo y consolidación de una sociedad que aspira impulsar su situación laboral y los preceptos de fortalecer una generación de emprendedores, que por obvias razones podrían abrir el camino necesario para el impulso empresarial. Las estrategias propuestas en los planes de gobierno de los países de la región han sido replanteadas luego de la presencia del Covid-19, buscando repotenciar sus procesos políticos y económicos frente a elevados niveles de endeudamiento externo, presiones inflacionarias, incremento de la delincuencia organizada y la posibilidad de establecer nexos con economías del primer mundo. Parte del análisis refleja que para el 2023 el panorama para la región no es muy alentador; sin embargo, cada país cuenta con su propio manejo político-económico con base en una realidad que se asemeja en los altos niveles de inflación, acelerada crisis migratoria, incremento de la violencia, desarticulación política y aumento de la extrema pobreza. Todo esto, frente a limitados planes de desarrollo social que en el corto o mediano plazo puedan dar las orientaciones mínimas necesarias para que el complejo momento por el que atraviesan, permita instaurar planes sobre la base de estrategias de madurez social y política.

Taking count: A computational analysis of data resources on academic LibGuides
Authors: Hennesy Cody , Kubas Alicia , McBurney Jenny
Published: July 2023

The LibGuides platform is a ubiquitous tool in academic libraries and is commonly used by librarians to compile and share lists of recommended social science numerical data resources with users. This study leverages the machine-accessible nature of the LibGuides platform to collect links to data and statistical resources from over 10,000 LibGuide pages at 123 R1 research institutions. After substantial data cleaning and normalization, an analysis of the most common resources on those guides provides a unique window into the data repositories, libraries, archives, statistical data platforms, and other machine-readable data sources that are most popular on academic library guides. Results show that freely available resources from U.S. government agencies are among the most common to be included on data and statistical resources guides across institutions. Resources requiring paid licenses or memberships for full access, such as Statistical Insight (ProQuest), Social Explorer, and ICPSR are linked to most frequently overall, regardless of the percentage of institutions that include them. Findings also suggest that libraries are more likely to share traditional licensed statistical resources (e.g., Cambridge’s Historical Statistics of the United States) and collections of simple charts and graphs (e.g., Statista) than more robust and complex microdata resources (e.g., IPUMS).

Published: July 2023

MSMEs (Micro, Small and Medium Enterprises) also contribute to Indonesia's economic growth. In running a business that is engaged in the MSME sector, there are many obstacles faced by most of the perpetrators, one of which is in terms of marketing. Based on research on MSMEs in the province of NTB, the number of MSMEs in Mataram City as of December 31, 2018 was 58,139 businesses. Although the government has made efforts to help MSME actors, there are still many MSMEs that are not yet known by the public so that sellers must promote their products in various places so that their products can be sold, one of which is by utilizing technology such as selling their products through applications. For this reason, in this study, the author builds an Android-based MSME marketplace application in the culinary field in the city of Mataram so that culinary MSME actors in the city of Mataram can promote and sell their products through the application. The process of making the application uses the SDLC (System Development Life Cycle) method with the waterfall model and testing with black box testing. In its design, the application is built using the Kotlin programming language and Firebase services. From testing after the application development process, the results from black box testing show that all test scenarios that have been made have been as expected. Furthermore, testing with MOS (Most Opinion Scrore) was also carried out and the results obtained were the average value of all respondents for a strongly agree score of 45.33%, agree at 34%, 16.67% for moderate, and 4.67% for disagree.

The effects of natural forest on the chemical properties of soil at different depths (0 to 30, 30 to 60 and 60 to 90 cm) were studied. There was a slight increase in pH in the sites under vegetation compared to open space, whereas no appreciable change in EC was observed. But substantial increase in cation exchange capacity, organic carbon content, total and available primary nutrients were recorded in the sites under vegetation compared to the contents in the open space. The effect of natural forest was more in surface soil (0 to 30cm) than in subsurface soil (30 to 60 and 60 to 90cm ). The underwood vegetation in the study area, leaf litter production over the period of establishment and nutrient concentration in leaf litter were also recorded.

Heterosis for seed yield and ilts components was estimated in 56 crosses obtained by crossing 4 cytoplasmic male sterile lines with 14 testers in L x T fashion. Co 4 and KBSH-1 were used as checks. The positive heterosis value ranged from 18.11 to 93.28 and 13.68 to 96.97 for seed yield respectively over mid parent and better parent. About 10 hybrids are recommended for further breeding work. It is inferred that parents with high mean values give high heterosis in combination.

A survey was conducted in Tamil Nadu to examine nodulation and Vesicular Arbuscular Mycorrhizal colonization of Casuarina equisetifolia using soil samples and root nodules (for use as a Frankia inoculum) collected from 23 provinces. Nodulation occurred more frequently on soils of higher available phosphorus status. This experiment supported the hypothesis that low phosphorus supply and the absence of infective Frankia were two of the factors responsible for the low frequency of nodulation in some soils. The VA-mycorrhizal fungi exhibited distinct distribution patterns when associated with Casuarina equisetifolia host in different habitats. The reduction in mycorrhizal activity was attributed to the high-P availability in the soil. The greater effectiveness of some inoculum for increasing P concentration in the host plant may indicate adaptation in these mycorrhizal fungi to low P soil conditions. Thus differences in nodulation and mycorrhizal infection may occur among native Frankia and VA-mycorrhizal fungi when the native soils are different yet contiguous.

Different animal excrements were assayed for fungitoxicity against Fusarium oxysporum f.sp. lycopersici, the causal agent of tomato wilt. Among them, cold and hot water extract of buffalo urine at 10 per cent concentration recorded complete inhibition of the mycelial growth. Physical properties like autoclaving at temperature 90°C for 10 minutes did not alter the toxicity. Toxin and hydrolytic enzyme production was also inhibited by buffalo urine. Seed treatment with buffalo urine enhanced the seed germination, growth and vigour of tomato seedlings.

Genetic diversity in 51 genotypes of Guinea grass was estimated through D analysis. The genotypes were grouped into seven clusters. The clustering pattern indicated no relationship between the genetic divergence and geographic distribution. The intra cluster generalised distance was the highest in cluster. 1 (35 genotypes) and lowest in cluster III (2 genotypes). The inter cluster distance was the highest between clusters IV and VII and was the least between clusters II and III. Cluster VI exhibited the maximum mean values for plant height, leaf weight, leaf-stem ratio and crude protein content and least value for crude fibre content. Cluster V recorded the maximum mean values for stem weight and green fodder yield per plant. The best genotypes from different clusters were identified for future crossing programme for improvement of green fodder yield and quality..
