Abstract

This study analyzes market reactions to the announcement of the Danantara Holding in conventional banks listed on the Indonesia Stock Exchange (IDX) using an event study methodology. Amidst the resilience of the Indonesian capital market in 2024 (IHSG: 7,036.57), the Danantara announcement on February 24, 2025, raises questions about the market's efficiency in absorbing structural policy information. The study aimed to examine the differences in Abnormal Return (AR) and Trading Volume Activity (TVA) before and after the announcement. This descriptive quantitative study used purposive sampling of 50 conventional banks, resulting in 12 samples (168 observations). Secondary data from the IDX, Yahoo Finance, and Investing.com were analyzed using a market-adjusted model, normality tests (Kolmogorov-Smirnov/Shapiro-Wilk), and the Wilcoxon Signed Rank Test using SPSS. The results show that the difference in AR is not significant (Sig. 0.827 > 0.05; mean: 0.0036 to -0.0005) but the increase in TVA is significantly positive (Sig. 0.000 < 0.05; mean: 0.0010 to 0.0016), rejecting both hypotheses. The findings confirm semi-strong market efficiency where structural policy information has been anticipated, consistent with the EMH and signaling theory.

Abstract

Background: Character education is a fundamental component of formal education, particularly in addressing moral and social challenges among students in contemporary society. Specific background: Literary texts grounded in local culture provide concrete representations of character values through narratives, traditions, and social interactions, as reflected in the novel Sanggarguri by Lalu Agus Fathurrahman. Knowledge gap: Previous studies on Sanggarguri have largely emphasized cultural and symbolic dimensions, while systematic analysis of character education values in relation to high school literature learning remains limited. Aims: This study aims to identify character education values embedded in the novel Sanggarguri and to describe their use within high school literature learning. Results: The analysis reveals five dominant values: respect, responsibility, tolerance, cooperation, and courage, manifested through characters’ attitudes, cultural rituals, and moral decision-making. Novelty: This study positions Sanggarguri as a local literary text that integrates Sasak cultural wisdom with character education values. Implications: The findings support the use of local novels as contextual teaching materials for high school literature learning, particularly in developing moral awareness, empathy, and cultural understanding in line with curriculum objectives. Highlights Identification of five core character education values in Sanggarguri. Representation of Sasak local wisdom through literary narratives and traditions. Suitability of the novel for high school literature learning contexts. Keywords Character Education, Novel Sanggarguri, Sasak Culture, High School Literature Learning, Local Wisdom

Abstract

Kasus Covid-19 telah menurun, namun tetap ada permintaan pemeriksaan Covid-19 dalam jumlah kecil. Metode ekstraksi RNA SARS CoV-2 telah banyak dikembangkan, mulai dari yang bersifat manual hingga otomatisasi. Metode otomatisasi lebih cepat dan efisien karena dapat melakukan ekstraksi banyak sampel per sekali pemeriksaan, namun biaya operasional alat cukup mahal. Jumlah permintaan pemeriksaan yang tidak banyak menyebabkan metode otomatisasi ini tidak efisien dalam hal biaya, sehingga perlu ditempuh usaha alternatif menggunakan metode manual. Perbedaan metode ekstraksi dapat memengaruhi konsentrasi RNA, sehingga pemilihan metode ekstraksi RNA yang tepat menjadi penting supaya didapatkan diagnosis yang akurat. Penelitian ini bertujuan untuk membandingkan konsentrasi RNA SARS CoV-2 dari hasil ekstraksi menggunakan metode spin column manual dan magnetic beads otomatis. Jenis penelitian ini adalah analitis numerik tidak berpasangan yang dilaksanakan di GSI Lab pada bulan April sampai Juni 2024. Penelitian ini menggunakan 30 sampel positif Covid-19 yang dilakukan ekstraksi dengan metode spin column manual dan magnetic beads otomatis. Hasil penelitian ini diuji dengan Mann Whitney. Konsentrasi RNA pada metode ekstraksi spin column manual dan magnetic beads otomatis berturut-turut adalah 3,9 (1,68 – 36,17) ng/µL dan 7,96 (2,28 – 113,59) ng/µL. Hasil uji Mann Whitney adalah 0,00 (nilai p< 0,05), yang berarti terdapat perbedaan yang bermakna antara hasil ekstraksi RNA dengan metode spin column manual dan magnetic beads otomatis. Keterbatasan penelitian ini adalah tidak mengkonfirmasi hasilnya dengan real time PCR.
