Mathematical literacy ability is one of the indispensable abilities in the development of mathematics education today. Currently, the mathematical literacy ability of students in Indonesia is still low. In the field of education, the era of society 5.0 has a great impact, so education must be able to produce human resources who have good mathematical literacy and are able to apply technology well with their literacy abilities. This study aims to determine how the quality of a project-based learning model with math trails assisted by augmented reality in the context of Blenduk Church is able to promote students' mathematical literacy. The research method used is design research. The data were analysed using qualitative and quantitative data analysis techniques. Qualitative data analysis techniques were used to analyse the results of student response questionnaires after conducting project-based learning with augmented reality-assisted math trails at Blenduk Church. Meanwhile, quantitative analysis techniques are used to analyse students' mathematical literacy skills obtained from student test results before and after conducting project-based learning with augmented reality-assisted math trails at Blenduk Church. However, further research is needed on the development of augmented reality-assisted learning instruments and media in other contexts to promote students' literacy skills.

Introduction The study area is located between Yiikselen-Osmancik and Kadinhani towns, about 40 km northwest of Konya. The area is included in the Afyon-Bolkardagi Zone (Okay, 1984), or in the Kiitahya-Bolkardag belt (Ozcan et al., 1988). Bozdag formation was first named by Dogan (1975) and its general field descriptions were reported by Eren (1993) and Kurt (1994). Bozdag formation, which can be observed as various shaped and isolated masses, include different grade metamorphosed limestone, dolomitic limestone and dolomite. The limestone is light grey, white in colour and generally massive to medium bedded (10-50 cm). The dolomite and dolomitic limestone are medium to thick bedded, black and dark grey in colour, which caused by very high contents of bituminous, and insoluble residue. They show very fine lamination and comprise widespread biostromes of Amphipora. When broken, all the dolomite and dolomitic limestone regardless of colour, give off a strong, petroliferous odour. The rocks of this formation, which metachert beds and chert lenses generally occurs in metacarbonate, are interfingering with each other laterally and vertically. The metacarbonate rocks contain corals, which are T h a m n o p o r a , S y r i n g o p o r a and C a n i n a , Stromatoporoid which is Amphipora, crinoids, fusulinide and algae. These fossils indicate a middle Devonian and early Carboniferous age for the formation. Otherwise the formation contains an abundant microfauna which is difficult to identify, due to metamorphism and recrystallization. These metacarbonates are cut by intrusive dykes and active volcanism and metasedimentary rocks also recorded in the surrounding area (Eren, 1993; Kurt, 1994). The aim of this research is to investigate the petrography and geochemistry of the metacarbonate rocks studied. Mineral identifications were made optically by X-ray diffraction methods. An analysis of major and trace elements was made by the X-ray fluorescence. Petrography The light coloured metacarbonate is composed of micrite cement, calcite, dolomite, biomicrite, coral and Fe-oxide. The calcite grain boundaries are sutured and are fragmented and set in a secondary calcite cement. Some coarse calcite crystals show deformation twinning, kinking and inclusion trails. The grain size distribution is unimodal. An abundance of such twinned lenses characterises as the twinning regime. Very small calcite grains are found mainly in the groundmass, but sometimes fill fossil cavities. Noncarbonate minerals accumulated along stylolites as insoluble residues, these residues also form the boundaries of veins, and this relationship indicates that some veins formed by void filling after formation of stylolite. Insoluble residues contain iron oxides, organic materials and sericite. The rocks show laminated zones and mosaic textures. Dark coloured, bituminous and partly dolomitized limestone consist of fine to medium crystalline sucrosic dolomite, biomicrites, pelmicrites, corals, with well developed crystalline microvuggy porosity. Dolomite has almost obliterated the original structure of the fossils. Very small calcite grains fill fossil cavities. The fine grained (0.1-1 mm) dolomite crystals are brownish and clearer rims. The texture is dominated largely elongation and characteristically have irregular and inter locking boundaries. Stylolitization occurs typically as a haphazard replacement of matrix and sparry calcite by irregular. Lithification after burial is partly supported by the preferred orientation of microfossil test and other grains (long axes are parallel with bedding) which is result of compaction and deformation. Geochemistry Two samples from dolomitized limestone were analysed for mineral compositions by XRD. Dolomitized limestone consist mainly dolomite (Fig. 1). 5 samples from limestone and 3 samples from dolomitized limestones were analysed for major and trace element composition by XRF method (Table 1).

The purpose of this study is to evaluate Corporate Social Responsibility (CSR) programs for local communities around mining companies in Kalimantan, Indonesia, based on environmental, economic, and social perspectives. We create evaluation criteria consisting of; six on the environmental perspective, three on the economic perspective, and two on the social perspective. CSR reports are collected from the company website. Each company was given a score based on whether these evaluation criteria were present (1) or absent (0). The evaluation scores of the CSR mining companies programs’ in Kalimantan, Indonesia are high in considering cleaner production, waste reduction, material flow management, and recycling, committed to managing energy and water, developing infrastructures surrounding mining companies, has good corporate ethics, and encourages employees to volunteer for social causes and provides incentives for these activities; medium in committed to following all applicable laws and policies concerning environmental standards and policies, committed to conserving biodiversity, committed to managing sound and vibration from mining activities as well as protecting the air quality around the mining area, and enhancing self-employment options for local communities; low in taking long-term factors into accounts, such as global climate change and other environmental threats, and providing jobs opportunities for local communities. From the evaluations above, access to information, public participation, and transparency in discussing areas of corporate-community issues are all things that mining companies must improve. If there is a lack of congruence between aim, activity, and effect, civil society organizations should frequently criticize mining companies' CSR operations.

For Universidad de Costa Rica, updating the questionnaire used to evaluate teaching performance through student perceptions is important because, as a public higher education institution, it is informed by the ongoing reflection on its actions. This article aims to describe the construction of a new version of the evaluation questionnaire, which is relevant to the field of academic excellence. A mixed approach was used through the combination of both quantitative and qualitative analysis techniques. Among the quantitative techniques, statistical calculation was used wiuniversity through the first semester in 2024; and among the qualitative techniques, focus groups were conducted by experts on the item bank constructed from the new teaching competency framework, as well as cognitive interviews. The result was a shorter questionnaire than the one previously used, adjusted to the new professional teaching competency framework. It is recommended that you consult the methodological process developed in this construction for future review, updating, or generation of new questionnaires.

The primary function of safety systems is avoiding personal injuries or death and environmental pollution. Major problem is that, at this moment, there is no standardised method for the assessment for safety in the process industry. Many companies and institutes use qualitative techniques for safety analysis while other companies and institutes use quantitative techniques. The authors of this paper will compare different quantitative and qualitative techniques and will show that different analysis techniques show widely different results. It will also be shown that the qualitative techniques are highly dependent on human judgement while the quantitative techniques suffer from highly uncertain underlying data. Therefore in the second part of the paper a new quantitative technique will be presented that can be used for the assessment of safety, availability and triprate in the process industry. This technique can take into account effects of uncertain data and identify parameters that influence safety and/or availability dominantly. Finally the paper presents an example of the new technique applied to a practical system used in Dutch petrochemical industry.

Background: Since the release of the King III report in 2009, and the adoption of these principles in the Johannesburg Securities Exchange (JSE) listing requirements, there has been a surge in integrated reporting guidelines, including the release of the International Integrated Reporting Council (IIRC) framework and Global Reporting Initiative (GRI) sustainability reporting standards, with an updated code for corporate governance, King IV, subsequently being published. These introductions have simulated a growth in research on integrated reporting; however, the impact of these initiatives on the annual integrated report (AIR) composition or format has not been explored. Aim: The objective of this article is to examine, compare and contrast identified trends in the composition of published AIRs following the release of the aforementioned guidelines. Setting: JSE-listed companies in the food and drug retail sector were analysed from 2009 to 2018. Methods: The study applied both qualitative and quantitative content analysis techniques to analyse the composition of AIRs. Results: The composition of AIRs of companies within the given sector and timespan has shifted, shown through a decrease in the number of pages containing annual financial statements and an increase in governance, strategy and sustainability information. Annual integrated reports have moved to explaining financial results with reference to full financial statements published online, with the other identified shifts coinciding closely with the release of integrated reporting developments. These results suggest that there has been an uptake in application of new reporting initiatives. Contribution: The article revealed that new reporting guidelines had been applied, generating a change in the composition of AIRs over the years, contributing to the body of knowledge on the reporting of economic, environmental and social perspectives. Conclusion: A comprehensive foundational study has been created that has illustrated that AIRs have developed in relation to new reporting initiatives.

Business sustainability has become the company ambition to ensure their business existence in the long term. Companies are competing to adopt sustainability objectives in every aspect of their operations. In the context of sustainability, the term triple bottom line (TBL) is widely known as an integration of economic perspectives, environmental perspectives, and social perspectives that underlie business operations. PT ABC is a bottled water company that adopt sustainability objective since the supplier selection process. It aims to ensure that only the right suppliers which deserve to enter the company's business ecosystem. Unfortunately, supplier selection criteria at PT ABC currently only focus on economic perspective. Environmental and social perspective have not yet significantly influenced supplier selection decisions. Therefore, this study aims to determine supplier selection criteria in PT ABC based on integration of economic, environmental, and social perspective. Integration of these three perspectives is important to strengthen supplier selection decisions alignment with business sustainability objectives. Researchers reviewed 100 scientific journals which discussed supplier selection criteria from 2012 to 2023. As a result, researchers set 13 selection criteria and 20 indicators that can be used to select suppliers at PT ABC.
