Published: August 2024

According to the Audit Reports of BPK Representative in West Sumatera Province with title “LHP on Compliance Audit of Regional Expenditures of West Sumatera Province for Fiscal Year of 2021”, and “LHP on Financial Statements Audit of West Sumatera Province for Fiscal Year of 2021” as well as the auction data from Electronic Procurement Portal (LPSE), it is known that there were 293 construction packages with tender procurement in West Sumatera Province during Fiscal Year of 2021. Of those 293 packages, there were 81 packages has caused public budget losses and potential budget losses with total amount of Rp1.935.987.094,02, lacks of revenue with total amount of Rp9.660.218.603,31, and there were 8 packages experienced contract termination. Of those 8 packages with contract termination, 5 packages were known to be under bid price or using bid price that was too low (less than 80% of the HPS Value). Termination of the contract has resulted in the work not being utilized for the community in a timely manner, the risk of quality degression of the abandoned work until the work is resumed, and the risk of public budget losses. This research was conducted by seeing and analyzing the bid price that is too low (under bid price) which has potential impact on contract termination and the risk of public budget losses as well as the relationship between bid price fixing issues and the causes of contract termination. This needs to be done so that the contract termination can be avoided and the results of construction works can be completed and utilized immediately. This study aims to find a causal relationship between under bid price issues and contract terminations and the risk of public budget losses through the causes that influence the occurrence of contract termination, starting from the determination of HPS and under bid price, the selection process, the preparation and the implementation of the works according to timeline. From this study, it can be concluded that under bid price has a lot of influences and is a trigger for contract termination which resulted in the risk of public budget losses. There needs to be a calculation of the real bid price by considering overhead expenses, potential increases in material and wage prices, other expenses, and unexpected expenses. In addition, the parties involved in the construction works should make a risk map in order to mitigate problems which occur during the contract implementation period. This research takes the study of water resources building construction projects. Thus, further research is still needed on the occurrence of contract termination in road and bridge construction projects.

The housing crisis in various cities in Indonesia has become an increasingly urgent issue. Rapid population growth and urbanization are major factors contributing to this crisis. One proposed solution is the development of high-rise building projects as a more practical and space-saving housing solution. However, in the context of high-rise construction, economic planning is crucial to ensure project sustainability. This research utilizes a quantitative method with secondary data collection. Life Cycle Cost (LCC) analysis is employed to control project costs from the initial stage to project completion, including construction, operational, maintenance, and demolition costs. The analysis results indicate that initial construction costs, operational costs, maintenance costs, and demolition costs all need to be considered in project planning. Maintenance and upkeep costs are crucial aspects in ensuring the building's sustainability throughout its economic life. By considering all these factors, the total life cycle cost of the construction of Rusun Polresta Bukittinggi during its operational period of 50 years amounts to Rp 32,064,519,750.22. The Annual Equivalent (AE) analysis shows an average annual cost of is Rp. 6,287,507,789.17.

Published: August 2024

Choosing the right roofing material is an important aspect of building design and construction. Both residential and commercial buildings have roof-related needs. But basically, the selection of roofing materials is not only for protection from but also based on energy efficiency, aesthetics, and longevity of the building. In addition, the design of roof shape selection must be done carefully because the wrong selection can cause rainwater seepage or leakage on the roof and high repair costs. This research aims to explore by comparing the characteristics of roof covering materials and provide the best choice based on needs. The research method used is a qualitative research method with the stages carried out, namely data collection techniques, sample determination, data analysis and research conclusions. Based on the analysis, it is concluded that for residential houses, tile roofs and concrete deck roofs are the best choice because they offer an optimal combination of aesthetics, durability, energy efficiency, and cost that is suitable for the Indonesian climate. While for commercial buildings, metal tile roof is an excellent choice due to its durability, energy efficiency, and modern aesthetics that suit the needs of commercial buildings.

Published: August 2024

The foundation is the most essential structural element of a building structure. A solid and stable foundation is a critical factor in ensuring the sustainability and safety of a building. Proper planning and calculations are essential in designing the foundation to withstand the structural loads from the building above it and ensure that the foundation does not experience dangerous settlement or collapse. In this research, the author conducted a study or examination of the condition of Silo Foundation PT XYZ is located in the Tangerang. The number of silo foundations built was 7 units (silo 17, silo 18, silo 19, silo 20, silo 21, silo 22 and silo 23). This silo is a vertical storage structure that functions as a place to store raw materials for animal feed. The condition of the silo foundation structure is known to have decreased after being filled to a maximum capacity of 5000T. To determine the condition of the foundation structure, it is necessary to carry out a measurement survey by checking levelling and verticality using reference standards or rules used by SNI 8640:2017. The results of foundation levelling tests for silo 17, silo 18, silo 19, silo 20, silo 21, silo 22 and silo 23 in Balaraja District, Tangerang Regency, there is the most significant elevation difference occurring at silo 19, namely 127 mm, which is based on SNI Geotechnical 8460-2017 Maximum building settlement is included in High Risk because the settlement is > 75 mm. The elevation differences in the other silos fall into the Small Risk to Medium Risk categories. Meanwhile, based on the results of checking verticality, it was found that the slope value of the structure in Silos 18, 19 and 21 experienced a slope that exceeded the maximum required permit limit of 20mm. Therefore, it is necessary to carry out regular inspections to monitor the movement or decline of the silo foundation so as not to cause risks or conditions of structural failure.

Published: August 2024

Gunung Sari Village, Batu City is a hilly mountainous area. Where the elevation contour of the land is at an altitude of ± 800 meters above sea level. Because of its hilly location, there are many steep slopes around the location. These slopes have the potential to experience landslides, considering that the rainfall in these locations is very high. Potential slopes with such conditions are suspected to have a safety factor (SF) < 1. For this reason, researchers are interested in analyzing the slopes on these slopes using the limit equilibrium method. In this study the method that will be used is to analyze the factor of safety in the existing conditions and the factor of safety after the slope is given geotextile reinforcement which will be modeled with the Geoslope/W 2012 application. The results of the safety factor analysis of existing conditions at cross 1 using the Geo Slope/W 2012 Program, the Bishop method, is 0.851, while for the Morgenstern method it is 0.961. Both methods show a safety factor value of less than 1 (F<1), which means the slope is unstable and has a high potential for landslides. The value of the safety factor with geotextile reinforcement for both methods has increased, making the slope more stable (F>1). The safety factor value for cross 1 of the Bishop method is 1.698 while for the Morgenstern method it is 1.702.

Learning at UPT SMPN 1 Sutera seems to be still low, this is because the learning model used by teachers is still not appropriate and the discussion process has not been carried out well. One way to overcome this problem is to apply the STEM integrated Problem-Based Learning (PBL) model. This research aims to determine the effect of the STEM integrated Problem-Based Learning (PBL) model on student learning outcomes in human respiratory and excretory system material at UPT SMPN 1 Sutera. The type of research used in the research is Quasi Experiment, namely a research method to find the effect of certain treatments on others under controlled conditions. The design used in this research is the Non-Equivalent Control Group Design. The population in this study were class VIII students at UPT SMPN 1 Sutera. The sample in this study consisted of two classes, namely the experimental class and the control class which were taken using a purposive sampling technique. The instruments used consisted of an observation sheet on the implementation of the STEM integrated PBL model, pre-test and post-test questions. The research data obtained was then analyzed through descriptive statistical tests and inferential statistics using SPSS version 25. Based on the results of the analysis in hypothesis testing, it showed that there was a significant average difference between the control and experimental classes. The results of research hypothesis testing were found to be 0.000 and smaller than 0.05. Thus, it can be seen that the significant difference between Ha is accepted and H0 is rejected, so there is an influence. The conclusion from the hypothesis test is that there is a significant influence between students' scores using the STEM integrated PBL learning model. So H0 is rejected and Ha is accepted. So there is an influence of the STEM integrated PBL model on student learning outcomes.

Published: August 2024

The transformation in the media landscape in Indonesia is underscored by the emergence of digital-centric media entities and a new mode of news production distinctly divergent from traditional journalism. The purpose of this study is to examine the evolving business model of digital journalism, a sector experiencing rapid growth following the advent of the internet, social media, and the consolidation of online journalism since 2010. Employing a qualitative-descriptive method, this research is designed to capture the digital journalism business model in Indonesia's post-traditional print and broadcast media systems. From 2021 to 2023, the authors meticulously observed the contents and management of selected news media outlets, conducted semi-structured interviews, and gathered pertinent documents. The key question of this study centers on the nature of the business model underpinning journalism on digital platforms and its repercussions for the interest of news production and publication. The study reveals that business models for digital news media remain unstandardized, and the ecosystem of platform-based journalism has yet to achieve a healthy climate. From the perspective of digital news consumption, the prevailing culture of gratuitous (free) news culture and the concern of keeping trusted news media pose significant obstacles for news corporations in sustaining their operations.
Lo que puede un lector en El aire
Authors: Carreras Mariano
Published: August 2024

El contexto de publicación de El aire, de Sergio Chejfec, coincide con el momento de consolidación hegemónica del neoliberalismo, cuyo rasgo fundamental consiste en el desplazamiento de la precariedad desde los márgenes que el capitalismo no puede integrar hacia el centro de la sociedad. Escrita y publicada en un tiempo que se caracteriza por un proceso de normalización de la precariedad, la novela produce, paradójicamente, un extrañamiento de la normalización. Chejfec propone una reflexión oblicua sobre la relación entre la novela como enunciado y sus propias condiciones de enunciación. Dicha reflexión se puede leer en las posiciones que asume el protagonista como consumidor cultural frente a distintos materiales textuales y en la distancia que lo separa de las condiciones de posibilidad de una poética particular, que en la novela se articula en la palabra del narrador.

In Kotabaru, there is a culture known as bakiauan for wedding banquets. It is an attitude of mutual cooperation between residents as a family and emotional strength to work together to minimize the high cost of wedding parties in their area that has been carried out for generations by the community. This article will analyze the culture in depth by considering two values, namely Islamic and socio-cultural values. This research aims to find out about how the culture of social norms and religiosity of the community integrate each other in this bakiauan culture. The method used in this research is the analysis of primary legal materials in the form of the Koran and relevant Hadiths, literature studies, and interviews with several Kotabaru people who have carried out this culture for generations with a sociological approach. Based on this, the results show that the preservation of this culture is motivated by a sense of family and strong emotional ties. So that with the announcement of a wedding party in their community, residents automatically come to help each other fulfill the various needs of the wedding event. The Islamic perspective is used to provide a view that the importance of a sense of Taawun (helping) between fellow humans to ease each other's burdens and an unbroken sense of friendship. The Socio-cultural perspective is used to explain the sociological aspects contained in this culture so that the sense of kinship between communities is getting stronger which goes straight with the noble culture of the Indonesian nation. This discussion leads to the importance of preserving this culture which has a positive influence on society, especially helping during sacred ceremonies, namely marriage events that require a lot of money. This article is expected to be able to contribute to readers about the importance of helping in matters of worship to get closer to God through the Bakiauan culture.

Published: August 2024

The COVID-19 pandemic has brought about a significant transformation in the global educational landscape, which has far-reaching implications for learning systems. This study focuses on the impact of the pandemic on India’s education sector, exploring its long-term consequences. The research delves into the enduring effects of COVID-19 and how it has reshaped traditional educational methods. The Indian education system has undergone a dynamic evolution, from the rapid integration of digital technologies to the redefinition of pedagogical approaches. The study employs surveys to comprehensively assess the multifaceted dimensions of adaptation. By synthesizing qualitative insights from 386 respondents, the research aims to contribute to a better understanding of the challenges, opportunities, and long-term implications of COVID-19. The hypothesis results show a significant difference among genders for factors 2 (consequences of COVID-19 on teachers, students, and teaching), 3 (impact of COVID-19 on education), and 4 (education system responses to COVID-19). In contrast, factor 3 is significant for education. Likewise, awareness factors 1 and 3 show that factors 1 (policies and strategies on education during COVID-19) and 5 (possible solutions and implementation) are significant for an application. Finally, binary logistic regression demonstrates that for gender factors three, education factors four, and five, online participation is significant for awareness factors one, three, and four. However, all of the factors are insignificant for an application. These findings can guide policy decisions, inform educational practices, and lay a valuable foundation for future research endeavours to shape a resilient, equitable, and innovative educational future.

The experiments were conducted to investigate the resistance levels among forty‑five lowland rice accessions at the Teaching and Research Farm, Federal College of Agriculture, Ishiagu (Latitude 5°56″N and Longitude 7°41″E) Ebonyi State, Nigeria. Forty‑five rice accessions were screened for their resistance to the blast disease in row planting during the 2017 and 2019 cropping seasons using Randomised Complete Block Design (RCBD) and were replicated thrice. The data on disease intensity and agronomic performance were subjected to Analysis of Variance and the significant means were separated with the Tukey HSD test at p < 0.05. Assessment of blast disease showed that the incidence, severity, and resistance levels varied significantly among rice tested. Accession NG / SA / JAN / 023 had the highest disease incidence (59.06 %) while accessions NG / SA / DEC / 07 / 0300, TOG 5453, TOG 6804, FARO‑22 and FARO‑57 had no blast symptoms for the two cropping seasons. The disease severity ranged from 0.00 to 3.43 for the two cropping seasons. Five accessions (NG / SA / DEC / 07 / 0300, TOG‑5453, TOG‑6804, FARO‑22, and FARO‑57) were highly resistant, 10 were resistant, 14 moderately resistant, and 16 were moderately susceptible to the disease. In the 2017 cropping season, the result of the grain yield showed that accession Local Foreign and FARO 26 had the value of 46.77 g apiece while NG / SA / DEC / 07 / 0278 had the least (11.00 g). However, in the 2019 cropping season, the results of the grain yield showed that accession Local Foreign produced the highest yield (56.00 g), FARO 26 had 40.31 g grain yield while NG / SA / DEC / 07 / 0285 (22.0 g) had the lowest grain yield. The study concluded that using the blast‑resistant cultivars is the best option in managing blast disease, and the five highly resistant accessions could be planted out in other agroecological zones for further studies on managing rice blast disease in the field.
Exploring and counteracting stage specific course completion risk factors in open higher education distance learning
Authors: Lyyra Pessi , Anttonen Sanna , Waselius Tomi
Published: August 2024

A major challenge for distance learning in higher education is supporting course completion. Counteracting completion risk factors requires investigating their significance across (non)completion stages. We tested the predictability of known risk factors at each completion stage. Not initiating was explained by available time, low motivation and completion methods. Abandonment was predicted by life situation and inappropriate completion methods. Failed submissions were explained by difficulty level and material availability. At early stages, supporting motivation by designing suitable course completion methods seems the most effective risk countermeasure. At later stages, academic skills protect from non-completion. Intrinsic motivation requires experiencing competence, autonomy and relatedness. Flexible distance learning methods with constructive, informational feedback and social interaction in the instructional design might best support course completion.
Electroless brassing of historical artefacts
Authors: Gerstner V. , Bureš R. , Stoulil J.
Published: August 2024

The topic of this work was the investigation of an alternative brassing technique consisting of electroless zinc plating of a copper object in a strongly alkaline solution and subsequent annealing to achieve a characteristic brass appearance. Within the scope of the work was the determination of the mechanism of zinc deposition on the copper surface, the optimisation of the NaOH concentration (30 and 40 wt. %), time of deposition (5-120 min), as well as temperature (150 and 200 °C) and annealing time (15 – 60 min). Electrochemical methods (potentiodynamic curves and open-circuit potential), metallography, X-ray diffraction (XRD), and glow-discharge optical emission spectroscopy (GD-OES) were used to study the brassing mechanism. Electrochemical measurements have shown that zinc powder significantly decreases the surface potential of copper to the value of zinc itself and also acts as a reducing agent. The diffusion of zinc in copper was found to occur during the primary deposition of zinc with the formation of the γ phase (Cu5Zn8). The optimal NaOH concentration is 40 wt.% and the deposition time is 60 min. The optimal conditions of annealing are 200 °C and 60 min. The primary γ phase is transformed during the annealing process into β and α phases.
Using green corrosion inhibitor to reduce maintenance cost for carbon steel saline water storage systems in the oil industry
Authors: Namus R. M. , Abass M. H. , Alali M. , Zedin N. K.
Published: August 2024

Carbon steel has long been used in storing the saline water that results from oil washing in the oil industry. However, a high corrosion rate is reported, resulting in significant economic losses for oil companies. In the Middle East oil field, the temperature touches 50⁰C in Summer, causing increasing in corrosion rate for saline water steel storage tanks and pipes. In the present work, abundantly available wheat straw was used to prepare a cost-effective silicate inhibitor. The high inhibition efficiency of up to 94 % decreased the corrosion rate from severe corrosion for no-inhibitor specimen to close to low corrosion category for optimum inhibitor concentration specimen. The mechanism of the inhibition effect is the formation of a chemically adsorbed layer on the steel surface, which is successfully described by Langmuir isotherm. Additionally, at high concentrations of nano-silica, complex aggregates might form and be physically adsorbed on the surface of steel above the chemically adsorbed nano-silicate monolayer.

[2-(3,4-epoxycyclohexyl) ethyl] triphenylsilane was synthesized, using triphenylsilane and 1,2-epoxy-4-vinylcyclohexane as the main raw materials. When the molar ratio of triphenylsilane to 1,2-epoxy-4-vinylcyclohexane was 1.0:1.2, the content of Wilkinson catalyst was 0.4%, the reaction temperature was 90°C, and the reaction time was 6 hours, the yield of [2-(3,4-epoxycyclohexyl) ethyl] triphenylsilane could reach 95.21%. The structure of the synthesized product was analyzed and characterized using FT-IR and 1H-NMR. The synthesized product was added to a bisphenol A-type epoxy resin (E-51) and a modified amine (593 amine) to prepare an adhesive. Then, the adhesive was poured into the mold and cured at 35°C for 8 hours. The cured sample exhibited the best performance when the ECETPS: E-51:593 amine molar ratio was 0.8:7.2:2. Thermal gravimetric analysis (TG) showed that the thermal stability of the cured samples increased relative to pure E-51 amine-cured samples with the synthesized product added. The mechanical properties of the samples were tested using a universal material testing machine, and the results showed a tensile strength of 37.95 MPa and a bending strength of 39.10 MPa.

This paper presents, describes and analyzes globalization and the global trending dimensions of the labor market and business in a challenging context. The research method started with an initial literature review then it focused on data analysis, interpretation and description, the research focus as well on creating frameworks illustrated in the part of analysis to analyze and illustrate some results and ideas. The research question is “how could globalization lead the labor market to a challenging context with and within the global trending dimensions? The results showed that globalization structured the labor market and economies and extended their global dimensions by facing facts such as skills, inflation, trade options, different economic sectors and societies, wage effects and even immigration. However, it always faces the question of employment and unemployment that affect the economy and the global society since it divided the world between developed and developing economies. In conclusion, globalization has led the labor market to a challenging context with global trending dimensions, negotiations and political adjustments are important to balance social and economic needs in order to avoid a global crisis, the labor market and its trends are important for both economic and social development.
Una Aproximación Conceptual a los Derechos Bioculturales. Origen y Consolidación
Authors: López Daza Germán Alfonso
Published: August 2024

En la actualidad, los movimientos ecologistas están fortaleciendo su discurso sobre la protección de los derechos ecológicos y el medio ambiente, con creciente reconocimiento en las cartas constitucionales y, en algunos casos, a través de la judicialización en diferentes países. Se está introduciendo un nuevo concepto que considera al medio ambiente y los ecosistemas no solo como objetos de cuidado, sino como elementos centrales en el desarrollo de las comunidades y sociedades. El siglo XXI ha visto una intensa degradación ambiental causada por la actividad humana, lo que ha llevado a un análisis profundo sobre las alternativas disponibles para la protección ambiental y la recuperación de ecosistemas dañados.
El derecho, como ciencia, no está ajeno a estos problemas y debe integrarse con otros campos del conocimiento para encontrar soluciones globales que afectan a toda la humanidad y comprometen a las futuras generaciones. Hay un debate en curso sobre una nueva categoría de derechos, que no se limita a los humanos sino que también podría incluir a elementos inanimados de la naturaleza, basándose en la creciente argumentación sobre el tema. Se está desarrollando una nueva categoría de derechos que considera a la naturaleza como sujeto de derechos, lo cual profundiza nuestra responsabilidad sobre el uso de los recursos naturales y nuestra intervención a través de principios jurídicos para defender este bien común.
La discusión actual sobre los derechos ecológicos ha sido más reactiva que preventiva, surgiendo principalmente de la necesidad de recuperar ecosistemas ya colapsados debido a la explotación de recursos y la contaminación. Ejemplos como el río Whanganui en Nueva Zelanda, el río Ganges en India y el río Atrato en Colombia muestran los primeros pasos hacia el reconocimiento de los derechos de los ríos, abriendo debates sobre su validez jurídica. El impulso para desarrollar y definir esta nueva categoría de derechos surge del ámbito académico y científico, con la expectativa de que la investigación conduzca a bases argumentativas sólidas y resultados científicos robustos.
Este enfoque tiene implicaciones nacionales e internacionales, incluyendo la determinación de acciones de protección, la identificación de partes legítimamente interesadas, y la revisión de la eficacia de las decisiones judiciales relacionadas. En resumen, este artículo explora la emergencia y aplicación de los derechos bioculturales, considerando la complejidad del cambio climático y ecosistémico del siglo XXI, junto con la emergencia del concepto de “Antropoceno” y las nuevas visiones de la “naturaleza-cultura”, en busca de justicia climática en un marco jurídico global.

The study was conducted at Horo district on six (6) farmers’ fields to investigate the effect of integrated vermicompost and chemical nitrogen fertilizer for bread wheat and the soil nutrient content. The treatments consist of without any fertilizer, recommended chemical NP fertilizer, 100% N equivalent vermicompost + recommended P2O5, 75% N equivalent Vermicompost + 25% recommended N + recommended P2O5, 50% equivalent Vermicompost + 50% recommended N + recommended P2O5 and 25% equivalent Vermicompost + 75% recommended N + recommended P2O5. The experimental design was a randomized complete block design (RCBD) with three replications. Dendea seed variety with a rate of 150 Kg ha-1 was used for the trial. ANOVA analysis for after harvesting soil parameters showed significant (P<0.05) differences among treatments for available phosphorus, organic carbon, exchangeable acidity and cations exchange capacity while pH and exchangeable Ca and Mg were not statistically significant among the treatments. ANOVA showed that the treatments significantly influenced all collected yield and yield related parameters of the crop. Relatively the highest crop yield and yield related traits were obtained from T2 (recommended chemical fertilizer) while the lowest was from control (without fertilizer). The highest net income (91971.70 birr/ha) was obtained from 25% equivalence vermicompost + 75% recommended N + recommended P2O5. To have more confidence in the technology; it should be verified in the same area with the same management procedure.

Orbital Impulsive Pursuit–Evasion Game Formulation and Stackelberg Equilibrium Solutions
Authors: Li Zhenyu , Luo Yazhong
Published: August 2024

The spacecraft pursuit–evasion game in orbit with impulsive maneuvers is investigated based on dynamic game theory. First, the game models are developed progressively from the single-impulse game to the multi-impulse game. In the models, the two-sided optimal strategies of both players form a Stackelberg equilibrium in single-impulse games and constitute a multistage Stackelberg equilibrium in multi-impulse games. Then, the optimality necessary conditions for the two equilibriums are derived and simplified as two multipoint boundary value problems (MPBVPs). To handle the complicated MPBVPs, a rolling backward induction based on the Lambert algorithm accompanied by a homotopy shooting method is proposed to solve the equilibrium solutions. Simulations showed the effectiveness of the proposed methods and verified that the obtained solutions are the (multistage) Stackelberg equilibrium. Meanwhile, the differences between the Stackelberg equilibrium and the Nash equilibrium are illustrated in detail. Finally, an analysis of the influence of the observation delay on the game results is provided.
