Abstract

Kurangnya pemahaman investor pemula mengenai analisis saham IPO menyebabkan keputusan investasi sering dilakukan tanpa pertimbangan kuantitatif yang memadai. Kegiatan Pengabdian Kepada Masyarakat (PKM) ini bertujuan memberikan edukasi dan pelatihan mengenai penggunaan model matematika sederhana dalam menentukan harga wajar saham IPO menggunakan metode Price Earning Ratio (P/E Ratio) serta estimasi peluang penjatahan saham melalui pendekatan probabilitas. Kegiatan dilaksanakan selama satu hari secara daring menggunakan aplikasi Zoom Meeting dengan metode ceramah, demonstrasi, praktik perhitungan, dan diskusi interaktif kepada 50 peserta yang terdiri dari mahasiswa dan masyarakat umum. Contoh saham IPO yang digunakan meliputi PT Wira Bakti Sejahtera Tbk (WBSA), PT Chandra Daya Investasi Tbk (CDIA), dan PT Hartadinata Abadi Tbk (EMAS). Hasil evaluasi pre-test dan post-test menunjukkan peningkatan rata-rata pemahaman peserta sebesar 47,8%, dari nilai rata-rata pre-test 34,4% menjadi 82,2% pada post-test. Sebanyak 74% peserta mencapai kategori nilai Sangat Baik (≥80) pada post-test. Peserta juga mampu melakukan simulasi perhitungan harga wajar dan probabilitas penjatahan secara mandiri. Kegiatan ini diharapkan dapat meningkatkan literasi keuangan masyarakat serta membantu investor pemula dalam mengambil keputusan investasi yang lebih rasional dan terukur.

Abstract

This research aims to develop LKPD based on Problem Based Instruction (PBI) for students' mathematical problem solving abilities. This type of research is the research and development (R&D) ADDIE development model. Validity, practicality and effectiveness are the three kinds of instruments to be analyzed. The research subjects for the validity test are lecturers as media experts and teachers as material experts. While the practical and effectiveness test subjects were thirty eighth graders. The research instruments used are questionnaires and tests. The data analysis techniques used are qualitative data analysis from validator comments and suggestions and quantitative data analysis in the form of scoring the percentage of validity, practicality and effectiveness of LKPD. Research conclusions: (1) Problem Based Instruction (PBI)-based LKPD on opportunity material meets the criteria, is very valid, very practical and very effective and can be used in the student learning process (2) Student learning outcomes after participating in learning using Problem Based Instruction (PBI)-based LKPD have met the expected problem-solving ability indicators.
