Abstract

Crude oil has important role in global economy, including Indonesia with considerable dependence on crude oil energy consumption. The increase in crude oil prices can be triggered by several factors, one of which is geopolitical conflict that occurred due to Russia's invasion of Ukraine on February 24, 2022. As the result, world crude oil prices rose above US$100 per barrel for the first time since 2014. Therefore, this study uses pulse function intervention analysis approach to evaluate the impact of certain events in predicting data over the next few periods. The pulse function is used because the intervention occurs at the moment t only. The data used starts from June 8, 2020 to September 19, 2022 on weekly basis with the proportion of training and testing data is 90:10. The best intervention model obtained is ARIMA (3,2,0) with b=0, s=1, r=2, and intervention point at T=91. The prediction results for the next 12 periods obtained MAPE value of 2.8982% and MSE of 10.2687. This study is expected to help reduce risks due to uncertainty in world crude oil prices and in line with the goals of the Sustainable Development Goals (SDGs) to ensure access to reliable, sustainable, and affordable energy.

Abstract

Perundungan di Sekolah Dasar (SD) merupakan masalah serius yang berdampak negatif terhadap perkembangan siswa. Penelitian ini bertujuan untuk mendeskripsikan strategi penanggulangan perundungan di SD, dengan menekankan urgensi dan dukungan stakeholder. Menggunakan pendekatan kuasi kualitatif dengan analisis tematik berbantuan perangkat lunak NVivo, data dikumpulkan melalui wawancara terhadap 14 guru SD di Kabupaten Belitung dan Kabupaten Bogor yang memiliki pengalaman menangani kasus perundungan dengan teknik purposive sampling Hasil penelitian menunjukkan bahwa strategi yang digunakan meliputi pendekatan emosional, bimbingan dan konseling, mediasi, dan sanksi edukatif. Kendala yang dihadapi antara lain siswa yang tidak melapor, ketidaksadaran pelaku, dan minimnya kolaborasi dengan orang tua. Meskipun sekolah telah memiliki Standar Operasional Prosedur (SOP), keberhasilan implementasi tetap bergantung pada komitmen para pelaksana di lapangan. Komitmen tersebut perlu didukung oleh kolaborasi antara kepala sekolah, konselor, orang tua, dan komunitas eksternal agar strategi yang diterapkan berjalan secara sistematis, berbasis nilai, dan berkelanjutan. Hasil temuan ini dapat diimplementasikan dengan memperkuat komunikasi dan koordinasi antar pihak terkait sehingga pelaksanaan program di sekolah menjadi lebih konsisten dan efektif.

Another problem is the worship and student monitoring reports can be lost because they are only summarized on paper. Not infrequently students are less honest when filling out their worship records because worship reports are not made routinely by the teacher. This is what motivates the author to design a web-based daily worship monitoring application.For students this application is designed with the hope of helping and making it easier for teachers and students to monitor the daily worship that has taken place. The research method used by the author is a research and development method. This method is a research method used to develop or validate products for use in education and learning. The research model used is the ADDIE model which is the Waterfall version of the development model, namely design, develop, implement, evaluate and SDLC. Monitoring of student worship, which is one of the activities in schools designed to monitor the performance of students' daily worship. This application is designed by the author using the PHP MySQLprogramming language. In this study, the authors conducted a trial for the product, namely using the effectiveness test, practicality test and effectiveness test. The research conducted by the author resulted in a web-based student worship monitoring application at SMA Negeri 1 V Koto Kampung Dalam. This app is available for students and teachers.

Abstract

This study investigates the impact of Problem-Based Learning (PBL) on the ecoliteracy abilities of grade VII junior high school students compared to conventional lecture-based instruction. Conducted at SMP Muhammadiyah 6 Krian, the quasi-experimental research involved 40 students divided into experimental and control groups. Pre-test and post-test assessments using ecoliteracy indicators were conducted. Results from T-tests showed no significant difference in ecoliteracy abilities between the two groups (experimental group: p = 0.090, control group: p = 0.270), suggesting that PBL did not significantly improve ecoliteracy skills among grade VII students. These findings underscore the need for further exploration of instructional methods to enhance ecoliteracy in junior high school settings. Highlight: PBL's Effect on Ecoliteracy: Assessing PBL's impact on junior high ecoliteracy. Quasi-Experimental Design: Non-equivalent control group method in research design. Call for Further Research: Identifying effective environmental education strategies.

Abstract

Indonesia is located in the ring of fire region. This condition causes Indonesia to have the potential to experience various disasters, such as volcano eruptions. In addition, rapid population growth has led to rampant land conversions that cause floods, landslides, tornadoes, droughts, and forest fires. The research aims to map natural disasters in Indonesia, especially Java Island to find out the provinces and their natural disasters tendency using Biplot analysis. Based on the results, Central Java, East Java, and West Java have a tendency to have floods and landslides. East Java tends to undergo earthquakes and Central Java has the potential to experience volcano eruptions. Through the natural disasters mapping, the government, especially the BMKG, will be able to find various solutions to overcome the natural disasters that have great potential to occur in provinces in Indonesia, especially Java Island as the manifestation toward SDGs Target 2030.

Abstract

Kriminalitas merupakan suatu perilaku yang melanggar hukum dan aturan dalam masyarakat. Penelitian ini dilakukan untuk menganalisis data biplot jumlah kejahatan di berbagai provinsi di Indonesia. Biplot merupakan analisis yang berguna untuk menafsirkan hubungan antara variabel dan objek dalam bentuk grafik tunggal. Sumber data dalam penelitian ini adalah data sekunder yang berasal dari website Badan Pusat Statistik yang berjudul “Statistik Kriminal 2022”. 34 kepolisian daerah yang mewakili setiap provinsi di Indonesia menjadi objek pengamatan dan 9 klasifikasi kejahatan menjadi variabel. Metode penelitian ini menggunakan analisis biplot dengan bantuan fiton. Dari nilai Dekomposisi Nilai Singular, keragaman data yang dapat dijelaskan sebesar 73,714%. Pada grafik analisis biplot hubungan antar observasi diperoleh bahwa observasi atau objek polda dari setiap provinsi tersebar terpusat pada satu kuadran. Hubungan antar variabel yang paling tinggi adalah korelasi antara variabel kejahatan narkotika dengan kejahatan yang berkaitan dengan penggelapan, penipuan, dan korupsi, sedangkan hubungan yang paling rendah adalah korelasi antara kejahatan narkotika dengan kejahatan terhadap ketertiban umum. Dalam hubungan observasi dengan variabel diperoleh 4 kelompok. Keberagaman variabel yang paling tinggi terletak pada kejahatan terhadap kebebasan masyarakat, sedangkan keberagaman variabel yang paling rendah terletak pada kejahatan terhadap kesusilaan.
