Abstract

Abstract. Real options are one of the most interesting research topics in Finance since 1977 Stewart C. Myers from MIT Sloan School of Management published his pioneering article on this subject in the Journal of Financial Economics. Real options are techniques for supporting capital budgeting decisions that adapt techniques developed for financial securities options. The purpose of using this real option is to capture the options contained in projects that cannot be captured by the discounted cash flow model which operates as a basic framework for almost all financial analyzes. The process of valuing real options will be complemented by the stochastic interest rate and stochastic volatility to better capture the flexibility and volatility of the existing economic and financial situation. The valuation will use a Monte Carlo simulation with the MATLAB programming language on crude oil data from the North Sea oil field. Data were obtained from the thesis of Charlie Grafström and Leo Lundquist with the title "Real Option Valuation vs. DCF Evaluation – An Application to a North Sea oilfield".Keyword: real options, stochastic interest rate model, stochastic volatility model, simulation

Abstract

Learning Management System (LMS) is an innovation in the learning process that allows online learning to be more effective and efficient. Like many other higher education institutions, Universitas Negeri Malang provides opportunities for innovation and easy access to knowledge by utilizing an LMS called the Sistem Pengelolaan Pembelajaran (SIPEJAR). SIPEJAR is an open-source system that can be modified according to the user's needs and desires. The aim of this research is to develop SIPEJAR content packages by using the ADDIE model for statistics for education courses with drone-based learning. SIPEJAR development products include lesson plans, textbooks, and SIPEJAR content packages for 16 meetings. Drone-based development is focused on developing explanatory videos, presentation slides, and student interaction with learning materials. The finding results indicated that the drone-based development of SIPEJAR content packages is valid with an average score of 3.77 out of 4, practical with an average score of 4.19 out of 5, and quite effective with classical completeness percentage obtained was 60% with an average score of 74.63. This means that drone-based SIPEJAR content packages have been well developed, even though they can be improved further. Our research findings indicated that the E-LKPD is valid with a percentage of 91.00%, practical with a percentage of 89.05%, and effective with a classical learning completeness percentage of 82.76%

Abstract

This study aims to explain the procedural fluency of students in numerical methods courses. Procedural fluency refers to knowledge of procedures, about when and how to use them appropriately, and the skills to carry out procedures flexibly, accurately, and efficiently. The method in this study uses a descriptive method with a qualitative approach and data analysis techniques for the Miles and Huberman models. In this study also performed triangulation of techniques by conducting interviews to strengthen the test result data. From the data analysis, it can be concluded that regarding the smoothness in students' procedural procedures in solving problems related to numerical methods courses, students are able to solve problems with more than one method. However, some students have not been able to streamline steps and make accurate calculations. In addition, mastery in operating a scientific calculator needs to be improved so that students can be more efficient and get more accurate answers.

Abstract

Kurangnya pelatihan teknis dan pendampingan praktis terkait penerapan deep learning pada guru menjadi hambatan bagi sekolah untuk mengoptimalisasi implementasi Kurikulum Merdeka. Kegiatan pengabdian ini memiliki tujuan untuk melatih 54 guru SMP 9 Malang agar mampu menyusun modul ajar berbasis deep learning secara mandiri dan kontekstual, membangun sistem pendampingan berkelanjutan melalui pembentukan community of practice (CoP), serta memublikasikan modul ajar inovatif hasil kegiatan ini sebagai model yang dapat direplikasi oleh sekolah-sekolah lain guna mendukung penerapan Kurikulum Merdeka secara lebih adaptif dan bermakna. Metode pengabdian menggunakan pendekatan Participatory Action Research (PAR) meliputi tiga tahap, yaitu persiapan, pelaksanaan inti, dan evaluasi. Hasil dari evaluasi menunjukkan bahwa pelatihan ini mampu memantik kesadaran guru akan pentingnya penyusunan modul berbasis deep learning dan mendorong untuk mengaplikasikannya secara nyata. Pemantauan dan pendampingan jarak jauh akan diterapkan agar guru dapat saling mendampingi dan menyempurkan modul dengan baik. Pelatihan ini menjadi contoh kolaborasi baik antara akademisi dan praktisi untuk mewujudkan pembelajaran mendalam di sekolah.
