Abstract

Asuransi Indonesia pernah alami kegagalan besar (Jiwasraya 2020-an, Prolife diinvestigasi). Hal itu mempertegas pentingnya pengawasan ketat pada emiten asuransi di BEI, terutama yang berkapitalisasi kecil dan likuiditas timpang. Penelitian ini menerapkan Isolation Forest untuk mendeteksi anomali volume dan harga saham sektor asuransi IDX menggunakan data harian End-of-Day periode 2 Januari 2020 hingga 29 Mei 2026. Audit likuiditas meloloskan 14 dari 18 saham (77,8%) ke tahap pemodelan; 4 saham (LPGI, ASRM, LIFE, ABDA) dikeluarkan karena proporsi hari tanpa transaksi berlebihan. Tiga fitur, yaitu log return, rasio volume relatif terhadap MA-20, dan rentang intraday relatif, melatih model per saham dengan ambang anomali pada persentil ke-5; fitur keempat yang direncanakan, yaitu rasio ukuran transaksi, tidak dapat dihitung karena keterbatasan data. Model mengidentifikasi 1.036 hari anomali (rata-rata 5,0% per saham, akibat konstruksi ambang batas, bukan temuan independen). Triangulasi terhadap kalender peristiwa hanya mengonfirmasi 42 anomali (4,1%), sementara enam anomali paling ekstrem tidak berkaitan dengan peristiwa mana pun. Anomali didominasi pola idiosyncratic (97,5% dari hari beranomali) dibanding sector-wide (2,5%), dengan satu hari ekstrem (5 Januari 2026) mencatat keserentakan penuh pada seluruh 14 saham yang memerlukan verifikasi lanjutan. Temuan ini mendukung kelayakan Isolation Forest sebagai alat pemantauan awal bagi investor dan regulator, dengan batasan metodologis yang ditandai eksplisit. Anomalies were dominated by idiosyncratic patterns (97.5% of anomalous days) rather than sector-wide patterns (2.5%), with one extreme day (January 5, 2026) showing complete synchrony across all 14 stocks, which requires further verification. These findings support the viability of Isolation Forest as an early-warning monitoring tool for investors and regulators, with its methodological limitations explicitly noted.

Abstract

 Abstract: Reading is a crucial basic skill for elementary school students as it forms the basis for understanding various subjects. However, some second-grade elementary school students still experience reading difficulties, such as not being fluent, not understanding the content, and having a low interest in reading. This study aims to determine the effect of picture storybooks containing character values ​​on the reading ability of second-grade elementary school students. This study used a quantitative approach with a pre-experimental design, a one-group pretest-posttest design. The subjects were 25 second-grade elementary school students. Data collection techniques included reading tests, observation, and documentation. Data were analyzed using normality tests, homogeneity tests, and t-tests. The results showed that the use of picture storybooks containing character values ​​can improve students' reading ability. This is evident in the increase in students' average scores before and after treatment, from 64.8 to 83.2. In addition to improving reading ability, picture storybooks also help instill character values ​​such as discipline, responsibility, cooperation, and honesty in students. Based on the results of the study, it can be concluded that picture storybooks containing character values ​​have a positive and significant effect on the reading ability of second-grade elementary school students. Keywords: picture story books, character values, reading ability, elementary school students Abstrak Kemampuan membaca merupakan keterampilan dasar yang sangat penting bagi siswa sekolah dasar karena menjadi dasar dalam memahami berbagai mata pelajaran.

Abstract

Abstract: The Government has transformed procurement from an administrative task into a tool for sustainable development that balances economic, social, and environmental dimensions. The Free Nutritious Meals (MBG) Program, as a strategic national policy, requires a procurement system that not only ensures the availability of nutritious food but also food commodities, supporting services, food processing, distribution, and the management of food residues and waste on a large scale This study aims to analyze the implementation of green procurement in the MBG Program based on Presidential Regulation Number 46 of 2025 concerning Government Procurement of Goods and Services, identify the challenges in its implementation, and formulate strategies for policy optimization. This research employs a normative legal research (doctrinal legal research) method using statutory, conceptual, and analytical approaches. The findings indicate that the application of Green Procurement principles in the MBG Program can be realized through the procurement of locally sourced food, efficient distribution systems, the use of environmentally friendly packaging, waste reduction initiatives, and strengthened supplier governance. The main challenges include the limited availability of green suppliers, inadequate human resource capacity, and insufficient monitoring systems. Policy optimization requires the digitalization of green procurement, the strengthening of technical regulations, and enhanced multi-stakeholder collaboration. Keywords: Green Procurement; Free Nutritious Meals; Presidential Regulation Number 46 of 2025   Abstrak: Perubahan paradigma pengadaan barang/jasa pemerintah (PBJP) mulai terjadi dari pendekatan administratif sampai dengan instrumen pembangunan berkelanjutan yang mengintegrasikan aspek ekonomi, sosial, dan lingkungan. Program Makan Bergizi Gratis (MBG) merupakan program nasional yang melibatkan pengadaan bahan pangan, jasa pendukung, pengolahan, distribusi, serta pengelolaan sisa pangan dan limbah dalam skala besar. Besarnya rantai pasok tersebut menjadikan pengadaan sebagai instrumen strategis untuk menerapkan prinsip ramah lingkungan. Penelitian ini bertujuan menganalisis implementasi pengadaan ramah lingkungan pada Program MBG berdasarkan Peraturan Presiden Nomor 46 Tahun 2025 tentang Pengadaan Barang/Jasa Pemerintah, mengidentifikasi tantangan pelaksanaannya, serta merumuskan strategi optimalisasi kebijakan. Metode peneliuttian menggunakan penelitian hukum normatif (doctrinal legal research) dengan pendekatan peraturan perundang-undangan (statute approach), konseptual (conceptual approach), dan analitis (analytical approach). Hasil penelitian menunjukkan bahwa penerapan prinsip Green Procurement dalam MBG dapat diwujudkan melalui pengadaan pangan lokal, efisiensi distribusi, penggunaan kemasan ramah lingkungan, pengurangan limbah, serta penguatan tata kelola penyedia. Tantangan utama meliputi keterbatasan penyedia hijau, kapasitas sumber daya manusia, dan sistem monitoring. Optimalisasi diperlukan melalui digitalisasi pengadaan hijau, penguatan regulasi teknis, serta kolaborasi multipihak. Kata kunci: Pengadaan Ramah Lingkungan; Makan Bergizi Gratis; Perpres 46 Tahun 2025.
