Abstract

Pemahaman konsep merupakan suatu aspek yang sangat penting dalam pembelajaran, dengan memahami konsep siswa dapat mengembangkan kemampuannya dalam setiap materi yang diajarkan.Penelitian ini bertujuan untuk meningkatkan pemahaman konsep siswa terhadap konsep matematika terutama pada geometri transformasi sehingga diberikan perlakuan pembelajaran matematika dengan memanfaat budaya, yaitu pada motif batik yogyakarta. Etnomatematika sebagai media dalam pembelajaran matematika juga bertujuan untuk mengenalkan dan melestarikan budaya yang ada di Indonesia. Penelitian ini di lakukan di SMA N 01 Bangunrejo, Kabupaten Lampung Tengah, Lampung. Penelitian ini merupakan penelitian eksperimen semu dengan melibatkan sampel sebanyak 41 siswa yang terbagi menjadi 2 kelas, yaitu kelas kontrol dan kelas eksperimen. Data yang terkumpul dianalisis menggunakan  . Berdasarkan hasil penelitian disimpulkan bahwa ada peningkatan pemahaman konsep geometri transformasi bermuatan etnomatematika pada motif batik ceplokan yogyakarta pada siswa kelas XI dimana diperoleh nilai   dan  , karena nilai   kurang dari   maka dapat disimpulkan bahwa etnomatematika pada motif ceplokan Yogyakarta dapat meningkatkan memahaman konsep matematika siwa.

Abstract

The grizzled leaf monkey (Presbytis comata) is a protected endemic species of West Java based on the Regulation of the Minister of Environment and Forestry Number P.106/MENLHK/SETJEN/KUM.1/12/2018 concerning Protected Plant and Animal Species. The research was conducted in May-June 2022 in the Gunung Botol Resort, Gunung Halimun Salak National Park. This research aims to identify population numbers and characteristics of the grizzled leaf monkey’s habitat. This research was carried out by observation using the modified line transect method. There were 21 grizzled leaf monkey individuals consisting of 19 individuals from five groups and two solitary individuals. The distribution of meeting points is at an altitude between 1.119-1.292 masl. The population density in the three blocks ranges from 12.5 to 60 individuals/km². The estimated grizzled leaf monkey population at the Gunung Botol Resort is 785 individuals. The group size of grizzled leaf monkeys ranges from 2-6 individuals. The age structure of grizzled leaf monkeys showed a value of 42.86% for the adults and 28.57% for the pre-adult and adolescents. The results of measurements of temperature obtained an average of 19.90-21.60°C with an air humidity of 71.87-90.51%. The slope of the research block ranges from 25-40%, and the altitude ranges from 1.119-1.292 masl. The diversity of vegetation types in the Gunung Botol Resort was found in 98 species and 43 families. The tree-level vegetation type that has the highest Importance Value Index is the ki merak (Eura javanica) at 105.69%. There were 15 species of grizzled leaf monkey fodder trees identified from 11 families. There are 6 species of grizzled leaf monkey sleeping trees identified and come from 4 families

Abstract

The COVID-19 pandemic has posed severe financial threats to companies across sectors, exposing weaknesses in traditional risk response systems. To address the increasing uncertainty and the need for rapid strategic adjustment, this study evaluates the role of the ISO 31000 risk management framework in enhancing corporate financial resilience during crises. The research aims to assess how the implementation of ISO 31000—including risk identification, analysis, evaluation, and mitigation—affects key indicators of financial stability: liquidity, solvency, operational continuity, and strategic financial adaptation. A mixed-method approach was employed, combining qualitative descriptive analysis and quantitative correlational analysis using Likert-scale questionnaire data. Regression analysis, t-tests, and F-tests were used to examine the influence of each risk management component, supported by reliability testing via Cronbach’s Alpha. The results show that the four ISO 31000 components jointly have a significant influence on all dimensions of financial resilience. Among them, risk mitigation shows the most consistent and significant effect, indicating its critical role in stabilizing companies during turbulent conditions. In contrast, risk analysis has the least statistical impact across the models. This study contributes empirical evidence supporting the strategic application of international risk management standards during global crises. The findings offer practical implications for organizations seeking to institutionalize structured risk governance and reinforce financial resilience. It also expands the academic discourse on risk-based financial management and encourages further exploration of adaptive frameworks in times of high uncertainty.
