Abstract

This research aims to analyze the dynamics of oil and gas exports in Indonesia during the period from 2012 to 2022 using the GARCH approach for forecasting volatility. The data utilized in this study encompass the monthly published volumes of Indonesia's oil and gas exports, sourced from the Indonesian Central Statistics Agency's website. The analysis involves a substantial amount of data, comprising 132 monthly time series spanning a significant timeframe. The findings indicate that the most suitable model for predicting oil and gas volumes is the GARCH (1,1) model. The GARCH approach is employed to model the volatility within the data of oil and gas exports. The results reveal the utilization of information criteria, including Akaike (14.73), Bayes (14.86), Shibata (14.73), and Hannan-Quinn (14.79). Moreover, the forecast analysis for the next ten periods depicts a consistent upward trend. Generally, these forecast results suggest that while the mean values of the data remain relatively stable, the volatility levels are anticipated to increase over the forthcoming periods. The implications of this research are crucial within the context of economic and international trade, as the volatility in oil and gas exports can significantly impact national economic policies and corporate decisions.

Abstract

Pembelajaran geometri di sekolah dasar menghadapi tantangan mengkonkretkan konsep abstrak spasial. Siswa kelas 3 SD Islam Nusantara mengalami kesulitan memahami orientasi ruang, bentuk geometri, dan visualisasi spasial karena keterbatasan pengalaman konkret. Penelitian ini mengeksplorasi pengalaman fenomenologis siswa dalam memahami konsep spasial melalui permainan tradisional engklek sebagai medium pembelajaran geometri yang otentik. Metode penelitian menggunakan pendekatan kualitatif fenomenologi dengan 12 siswa kelas 3 SD Islam Nusantara Kota Pekalongan yang dipilih purposive sampling. Pengumpulan data dilakukan melalui observasi partisipatif, wawancara mendalam, dan dokumentasi selama 8 minggu dengan frekuensi 3 kali pertemuan per minggu. Aspek observasi difokuskan pada pola gerakan tubuh, interaksi dengan bentuk geometri petak engklek, strategi spasial lompatan, kolaborasi matematika, ekspresi pemahaman konsep, dan transfer pengetahuan geometri. Aspek wawancara meliputi persepsi bentuk geometri, pengalaman embodied orientasi ruang, strategi kognitif visualisasi spasial, makna personal pembelajaran geometri, refleksi perubahan pemahaman, dan kemampuan mengaitkan konsep dengan lingkungan sekitar. Analisis data menggunakan model Colaizzi dengan triangulasi melalui member checking dan peer debriefing. Hasil menunjukkan permainan engklek memfasilitasi pemahaman konsep spasial melalui tiga dimensi: orientasi spasial embodied melalui gerakan tubuh terstruktur, pemahaman geometri kontekstual melalui interaksi pola petak beragam, dan pengembangan visualisasi ruang kolaboratif melalui strategi lompatan dan diskusi kelompok. Siswa mengalami transformasi dari pemahaman abstrak menjadi embodied cognition bermakna dengan peningkatan akurasi identifikasi bentuk geometri 89%. Interaksi sosial memperkuat konstruksi pengetahuan spasial melalui collaborative learning.

Abstract

This qualitative study aims to analyze the implementation of corn seed media as an innovation in learning addition and subtraction arithmetic operations in Class 2 of SD Negeri 02 Sokosari. This study uses a case study approach with data collection techniques through participatory observation, in-depth interviews with teachers and students, and analysis of learning documents. The results of the study indicate that corn seed media is effective in improving students' conceptual understanding, especially for students with kinesthetic learning styles. The learning process goes through three main phases: introduction, operational, and evaluation, with 75% of students showing significant improvement in solving math problems. The findings also reveal that this media acts as a scaffolding that facilitates the transition of understanding from the concrete to the abstract stage, in accordance with Bruner's theory. The main obstacles include time management and classroom cleanliness, while positive responses come from teachers and students who consider this media fun and easy to access. This study recommends further development with the DECO (Discover, Engage, Contextualize, Optimize) approach and the need for school policies that support the use of local resources in learning. The implications of the study emphasize the importance of context-based media to create meaningful mathematics learning in elementary schools.

Abstract

One of the most widely used methods of survival analysis is Cox proportional hazard regression. It is a semiparametric regression used to investigate the effects of a number of variables on the dependent variable based on survival time. Using the Cox proportional hazard regression method, this study aims to estimate the factors that influence the survival of patients with type 2 diabetes mellitus. The estimated parameter values, as well as the Cox Regression equation model, were also investigated. A total of 1293 diabetic patients with type 2 diabetes were studied, with data taken from medical records at PKU Muhammadiyah Hospital in Yogyakarta, Indonesia. These variables have regression coefficients of 1.36, 1.59, -0.63, 0.11, and 0.51, respectively. Furthermore, the results showed the hazard ratio for female patients was 1.16 times male patients. Patients on insulin treatment had a 4.92-fold higher risk of death than those on other therapy profiles. Patients with normal blood sugar levels (GDS 140 mg/dl) had a 1.12 times higher risk of death than those with other blood glucose levels. Type 2 diabetes mellitus is a challenge for many Indonesians, in addition to being a deadly condition that was initially difficult to diagnose. As a result, patient survival analysis is needed to reduce the patient's risk of death.
