The failure of students in studying complex analysis courses is based on student learning habits that only focus on memorizing concepts from the material studied without understanding it properly, and lack of motivation to repeat the material that has been studied. The teaching materials used in this course are textbooks. However, the textbook used still does not contain activities for students' mathematical reasoning abilities, students cannot learn independently from the book, because the material presented is difficult to understand, even lecturers who teach this complex analysis course have to redesign the material, writing in written form. hand is then given to the student. One effort that could be to improve students' mathematical reasoning abilities is to facilitate learning resources with supporting teaching materials. In this study, teaching materials will be designed based on mathematical reasoning activities using the Missauri Mathematical Project (MMP) learning model. The research method used in this research is the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) development model. The development of complex analysis textbooks based on reasoning activities using the Missauri Mathematical Project learning model is feasible to be developed with the percentage of assessment by media expert validators obtained an average score of 91.79% in the "very valid" categories, and media expert validators obtained the average score. a score of 88.62% with the "very valid" categories. The results of the small group validation obtained a score of 83.5% with the "very valid" criteria. The results of the large group trial obtained a score of 85.5% with the "very practical" criteria. Abstrak Salah satu kendala dalam mata kuliah analisis kompleks adalah kegagalan mahasiswa dalam mempelajari materi yang disebabkan oleh kebiasaan belajar mahasiswa yang hanya terfokus untuk menghafal konsep dari materi yang diajarkan tanpa memahaminya secara mendalam, serta kurangnya motivasi untuk mengkaji ulang materi yang telah dipelajari. Sumber utama yang digunakan sebagai bahan ajar pada mata kuliah ini yaitu buku paket. Namun, buku paket yang digunakan masih belum memuat aktivitas kemampuan penalaran matematis mahasiswa, mahasiswa tidak bisa belajar secara mandiri dari buku tersebut, karena materi yang disajikan sulit untuk dipahami, bahkan dosen yang mengajarkan mata kuliah analisis kompleks ini harus mendesain ulang materinya, menulis dengan tulisan tangan kemudian diberikan kepada mahasiswa. Salah satu usaha yang bisa dilakukan untuk meningkatkan kemampuan penalaran matematis mahasiswa adalah dengan memfasilitasi sumber belajar dengan bahan ajar yang mendukung. Dalam penelitian pengembangan ini, bahan ajar akan disusun dengan berbasis aktivitas penalaran matematis menggunakan model pembelajaran missauri mathematic project. Metode penelitian yang dipakai dalam penelitian ini yaitu model pengembangan analysis, design, development, implementation, and evaluation. Pengembangan buku ajar analisis kompleks berbasis aktivitas penlaran dengan menggunakan model pembelajaran missauri mathematic project layak dikembangkan dengan persentase penilaian oleh validator ahli media diperoleh skor rata-rata sebesar 91,79% dengan kriteria “sangat valid”, dan validator ahli media didapat hasil skor rata-rata sebesar 88,62% dengan kriteria “sangat valid”. Hasil validasi kelompok kecil didapat nilai sebesar 83,5% dengan kriteria “sangat valid”. Hasil uji coba kelompok besar didapat nilai sebesar 85,5% dengan kriteria “sangat praktis”.

This study was motivated by problems and unrest against the number of cases of victims exposed to COVID-19 increased during the Covid-19 Pandemic period. In this study, the authors analyzed five banner texts that focused on the appeal on how to minimize the spread of COVID-19. This study aims to determine messages related to how to overcome the application of the application of 5 M application found in banners, benner, and community service advertisements. As well as the meaning contained in the text of the 5 M application message about Covid-19. Data collection techniques with library research or library research with a hermeneutics approach. This thesis uses hermeneutics theory Hans-Georg Gadamer. With this hermenetuika theory, a message of 5 m is found through historical, dialectics and application. The results of this study indicate that in the text found a message related to the application of 5 m, namely the distribution of messages invites the public to comply with the things that have been determined by the government about the dangers of Covid-19, containing relevant sentences that cause close relationships and relationships related to the problem being faced in the middle public. In receiving a message it needs to be considered related to the truth of the message itself. Given that a message that is not clear truth can lead to chaos and the increasing number of Covid-19 cases among the people. Thus, researchers also suggest that people always do a message of application of 5 M that has been implemented by the government.

The purpose of this study is to investigate the impact of environmental innovation which is product innovation (PDI) and process innovation (PCI) on firm’s financial performance (FFP). And also, to investigate mediating role of the environment management accounting (EMA) against innovation and FFP. Data were collected from 98 respondents, worked in management positions in Indonesia’s manufacturing sectors. The study uses PLS-SEM (partial least square based structural equation modeling) software for the data analysis. The results showed that PDI has positive and significant impacts on FFP. But PCI has not significant impacts on FFP. Furthermore, PDI and PCI have significant impacts on EMA. This study also indicated that EMA mediate the relationship between innovation and FFP in the manufacturing sector of Indonesia. This study suggests the managers of the manufacturing companies or similar sectors to introduce innovations in their products and processes for developing a better EMA system. The current study also tends to assist policymakers in developing appropriate policies for the manufacturing sector of Indonesia by realizing the importance of environmental innovation, EMA, so that their environmental and economic impacts can be managed and regulated.

Mechanisms for motivating and involving teachers in learning and working together with their colleagues are currently quite scarce. This study aims to explore the conditions that support teacher professional development in inquiry based learning through learning communities and examine how teacher professional development will impact students learning outcomes. The five teachers selected were a group of teachers who were members of the lesson study community at SMP Negeri 11 Bengkulu city and participated in this study. The qualitative results in this study reveal that the interactive domain, in which the teacher’s professional learning community works collaboratively by sharing teaching experiences and developing assessment tools, plays an important role in promoting teacher professional development. These results reinforce the understanding that conditions and important supporting mechanisms that must be possessed by an effective model for teachers professional development can lead to improved students learning outcomes.
